Initial support for clipboard on OS X. Rather than trying to get my existing hugely complicated X-style clipboard code to somehow work with the Quartz GTK back end, I've written an entirely new and much simpler alternative clipboard handler usnig the higher-leve GtkClipboard interface. It assumes all clipboard text can be converted to and from UTF-8 sensibly (which isn't a good assumption on all front ends, but on OS X I think it's reasonable), and it talks to GDK_SELECTION_CLIPBOARD rather than PRIMARY, which is the only clipboard OS X has. I had to do a fiddly thing to cope with the fact that each call to gtk_clipboard_set_with_data caused a call to the clipboard clear function left over from the previous set of data, so I had to avoid mistaking that for a clipboard-clear for the _new_ data and immediately deselecting it. I did that by allocating a distinct placeholder object in memory for each instance of the copy operation, so that I can tell whether a clipboard-clear is for the current copy or a previous one. This is only very basic support which demonstrates successful copying and pasting is at least possible. For a sensible OS X implementation we'll need a more believable means of generating a paste UI action (it's quite easy to find a Mac on which neither Shift-Ins nor the third mouse button even exists!). Also, after the trouble I had with the clipboard-clear event, it's a bit annoying to find that it _doesn't_ seem to get called when another application becomes the clipboard owner. That may just be something we have to put up with, if I can't find any reason why it's failing.

Stop using the GTK "configure-event" signal. I've been using that signal since the very first commit of this source file, as a combined way to be notified when the size of the drawing area changes (typically due to user window resizing actions) and also when the drawing area is first created and available to be drawn on. Unfortunately, testing on Ubuntu 18.04, I ran into an oddity, in which the call to gtk_widget_show(inst->window) in new_session_window() has the side effect of delivering a spurious configure_event on the drawing area with size 1x46 pixels. This causes the terminal to resize itself to 1 column wide, and the mistake isn't rectified until a followup configure-event arrives after new_session_window returns to the GTK main loop. But that means terminal output can occur between those two configure events (the connection-sharing "Reusing a shared connection to host.name" is a good example), and when it does, it gets embarrassingly wrapped at one character per line down the left column. I briefly tried to bodge around this by trying to heuristically guess which configure events were real and which were spurious, but I have no faith in that strategy continuing to work. I think a better approach is to abandon configure-event completely, and move to a system in which the two purposes I was using it for are handled by two _different_ GTK signals, namely "size-allocate" (for knowing when we get resized) and "realize" (for knowing when the drawing area physically exists for us to start setting up Cairo or GDK machinery). The result seems to have fixed the silly one-column wrapping bug, and retained the ability to handle window resizes, on every GTK version I have conveniently available to test on, including GTK 3 both before and after these spurious configures started to happen.

Basic support for running under GDK Wayland back end. GTK 3 PuTTY/pterm has always assumed that if it was compiled with _support_ for talking to the raw X11 layer underneath GTK and GDK, then it was entitled to expect that raw X11 layer to exist at all times, i.e. that GDK_DISPLAY_XDISPLAY would return a meaningful X display that it could do useful things with. So if you ran it over the GDK Wayland backend, it would immediately segfault. Modern GTK applications need to cope with multiple GDK backends at run time. It's fine for GTK PuTTY to _contain_ the code to find and use underlying X11 primitives like the display and the X window id, but it should be prepared to find that it's running on Wayland (or something else again!) so those functions don't return anything useful - in which case it should degrade gracefully to the subset of functionality that can be accessed through backend-independent GTK calls. Accordingly, I've centralised the use of GDK_DISPLAY_XDISPLAY into a support function get_x_display() in gtkmisc.c, which starts by checking that there actually is one first. All previous direct uses of GDK_*_XDISPLAY now go via that function, and check the result for NULL afterwards. (To save faffing about calling that function too many times, I'm also caching the display pointer in more places, and passing it as an extra argument to various subfunctions, mostly in gtkfont.c.) Similarly, the get_windowid() function that retrieves the window id to put in the environment of pterm's child process has to be prepared for there not to be a window id. This isn't a complete fix for all Wayland-related problems. The other one I'm currently aware of is that the default font is "server:fixed", which is a bad default now that it won't be available on all backends. And I expect that further problems will show up with more testing. But it's a start.

Use a Cairo image surface as a client-side cache. In any DRAWTYPE_CAIRO mode, we now do all our Cairo drawing to a Cairo image surface which lives on the client; then we either blit directly from that to the window (if we're in GTK3 mode, or GTK2 without deprecated pieces of API), or else we blit from the Cairo surface to the server-side pixmap and then from there to the actual window. In DRAWTYPE_GDK mode, nothing much has changed: we still draw directly to the server-side pixmap using the GDK drawing API, then blit from there to the window. But there is one change, namely that the blit is no longer done proactively - instead, we queue a redraw of the affected rectangle, and wait until we're called back by the expose handler. The main aim of all this is to arrange that the only time we ever draw to the real window is in response to expose/draw events. The experimental GTK3 OS X port stopped working a week or two ago (I presume in response to an OS update) with the symptoms that attempts to draw on the window outside the context of a "draw" event handler just didn't seem to work any more; this change fixes it. In addition to that benefit, this change also has obvious performance advantages in principle. No more expensive text rendering in response to an expose event - just re-copy to the window from the bitmap we already have, from wherever it's stored that's nearest. Moreover, this seems to have fixed the significant performance problem with X server-side fonts under GTK. I didn't expect _that_! I'd guessed that the approach of downloading character bitmaps and rendering them manually via Cairo was just inherently slow for some reason. I've no real idea _why_ this change improves matters so much; my best guess is that perhaps there's an overhead in each drawing operation to a GDK Cairo surface, so we win by doing lots of operations to a much faster image surface and then batching them up into one GDK Cairo operation. But whyever it is, I'm certainly not complaining! (In fact, it now seems to be noticeably _faster_, at least on my usual local X displays, to draw server-side fonts using that technique than using the old GDK approach. I may yet decide to switch over...)

GTK 3: be aware of the window's scale factor. In GTK 3.10 and above, high-DPI support is arranged by each window having a property called a 'scale factor', which translates logical pixels as seen by most of the GTK API (widget and window sizes and positions, coordinates in the "draw" event, etc) into the physical pixels on the screen. This is handled more or less transparently, except that one side effect is that your Cairo-based drawing code had better be able to cope with that scaling without getting confused. PuTTY's isn't, because we do all our serious drawing on a separate Cairo surface we made ourselves, and then blit subrectangles of that to the window during updates. This has two bad consequences. Firstly, our surface has a size derived from what GTK told us the drawing area size is, i.e. corresponding to GTK's _logical_ pixels, so when the scale factor is (say) 2, our drawing takes place at half size and then gets scaled up by the final blit in the draw event, making it look blurry and unpleasant. Secondly, those final blits seem to end up offset by half a pixel, so that a second blit over the same subrectangle doesn't _quite_ completely wipe out the previously blitted data - so there's a ghostly rectangle left behind everywhere the cursor has been. It's not that GTK doesn't _let_ you find out the scale factor; it's just that it's in an out-of-the-way piece of API that you have to call specially. So now we do: our backing surface is now created at a pixel resolution matching the screen's real pixels, and we translate GTK's scale factor into an ordinary cairo_scale() before we commence drawing. So we still end up drawing the same text at the same size - and this strategy also means that non-text elements like cursor outlines and underlining will be scaled up with the screen DPI rather than stubbornly staying one physical pixel thick - but now it's nice and sharp at full screen resolution, and the subrectangle blits in the draw event are back to affecting the exact set of pixels we expect them to. One silly consequence is that, immediately after removing the last one, I've installed a handler for the GTK "configure-event" signal! That's because the GTK 3 docs claim that that's how you get notified that your scale factor has changed at run time (e.g. if you reconfigure the scale factor of a whole monitor in the GNOME settings dialog). Actually in practice I seem to find out via the "draw" event before "configure" bothers to tell me, but now I've got a usefully idempotent function for 'check whether the scale factor has changed and sort it out if so', I don't see any harm in calling it from anywhere it _might_ be useful.

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

Refactor the GTK drawing system to do both GDK and Cairo. We're going to have to use Cairo in the GTK3 port, because that's all GTK3 supports; but we still need old-style GDK for GTK1 support, and also for performance reasons in GTK2 (see below). Hence, this change completely restructures GTK PuTTY's drawing code so that there's a central 'drawing context' structure which contains a type code indicating GDK or Cairo, and then either some GDK gubbins or some Cairo gubbins as appropriate; all actual drawing is abstracted through a set of routines which test the type code in that structure and do one thing or another. And because the type code is tested at run time, both sets of drawing primitives can be compiled in at once, and where possible, they will be. X server-side bitmap fonts are still supported in the Cairo world, but because Cairo drawing is entirely client-side, they have to work by cheekily downloading each glyph bitmap from the server when it's first needed, and building up a client-side cache of 'cairo_surface_t's containing the bitmaps with which we then draw on the window. This technique works, but it's rather slow; hence, even in GTK2, we keep the GDK drawing back end compiled in, and switch over to it when the main selected font is a bitmap one. One visible effect of the new Cairo routines is in the double-width and double-height text you can get by sending ESC # 3, ESC # 4 and ESC # 6 escape sequences. In GDK, that's always been done by a really horrible process of manually scaling the bitmap, server-side, column by column and row by row, causing each pixel to be exactly doubled or quadrupled. But in Cairo, we can just set a transformation matrix, and then that takes effect _before_ the scalable fonts are rendered - so the results are visibly nicer, and use all the available resolution. (Sadly, if you're using a server-side bitmap font as your primary one, then the GDK backend will be selected for all drawing in the terminal as a whole - so in that situation, even fallback characters absent from the primary font and rendered by Pango will get the old GDK scaling treatment. It's only if your main font is scalable, so that the Cairo backend is selected, that DW/DH characters will come out looking nice.)

Hence, this change completely restructures GTK PuTTY's drawing code so that there's a central 'drawing context' structure which contains a type code indicating GDK or Cairo, and then either some GDK gubbins or some Cairo gubbins as appropriate; all actual drawing is abstracted through a set of routines which test the type code in that structure and do one thing or another. And because the type code is tested at run time, both sets of drawing primitives can be compiled in at once, and where possible, they will be. X server-side bitmap fonts are still supported in the Cairo world, but because Cairo drawing is entirely client-side, they have to work by cheekily downloading each glyph bitmap from the server when it's first needed, and building up a client-side cache of 'cairo_surface_t's containing the bitmaps with which we then draw on the window. This technique works, but it's rather slow; hence, even in GTK2, we keep the GDK drawing back end compiled in, and switch over to it when the main selected font is a bitmap one. One visible effect of the new Cairo routines is in the double-width and double-height text you can get by sending ESC # 3, ESC # 4 and ESC # 6 escape sequences. In GDK, that's always been done by a really horrible process of manually scaling the bitmap, server-side, column by column and row by row, causing each pixel to be exactly doubled or quadrupled. But in Cairo, we can just set a transformation matrix, and then that takes effect _before_ the scalable fonts are rendered - so the results are visibly nicer, and use all the available resolution. (Sadly, if you're using a server-side bitmap font as your primary one, then the GDK backend will be selected for all drawing in the terminal as a whole - so in that situation, even fallback characters absent from the primary font and rendered by Pango will get the old GDK scaling treatment. It's only if your main font is scalable, so that the Cairo backend is selected, that DW/DH characters will come out looking nice.)

I've been using that signal since the very first commit of this source file, as a combined way to be notified when the size of the drawing area changes (typically due to user window resizing actions) and also when the drawing area is first created and available to be drawn on. Unfortunately, testing on Ubuntu 18.04, I ran into an oddity, in which the call to gtk_widget_show(inst->window) in new_session_window() has the side effect of delivering a spurious configure_event on the drawing area with size 1x46 pixels. This causes the terminal to resize itself to 1 column wide, and the mistake isn't rectified until a followup configure-event arrives after new_session_window returns to the GTK main loop. But that means terminal output can occur between those two configure events (the connection-sharing "Reusing a shared connection to host.name" is a good example), and when it does, it gets embarrassingly wrapped at one character per line down the left column. I briefly tried to bodge around this by trying to heuristically guess which configure events were real and which were spurious, but I have no faith in that strategy continuing to work. I think a better approach is to abandon configure-event completely, and move to a system in which the two purposes I was using it for are handled by two _different_ GTK signals, namely "size-allocate" (for knowing when we get resized) and "realize" (for knowing when the drawing area physically exists for us to start setting up Cairo or GDK machinery). The result seems to have fixed the silly one-column wrapping bug, and retained the ability to handle window resizes, on every GTK version I have conveniently available to test on, including GTK 3 both before and after these spurious configures started to happen.

GTK 3: be aware of the window's scale factor. In GTK 3.10 and above, high-DPI support is arranged by each window having a property called a 'scale factor', which translates logical pixels as seen by most of the GTK API (widget and window sizes and positions, coordinates in the "draw" event, etc) into the physical pixels on the screen. This is handled more or less transparently, except that one side effect is that your Cairo-based drawing code had better be able to cope with that scaling without getting confused. PuTTY's isn't, because we do all our serious drawing on a separate Cairo surface we made ourselves, and then blit subrectangles of that to the window during updates. This has two bad consequences. Firstly, our surface has a size derived from what GTK told us the drawing area size is, i.e. corresponding to GTK's _logical_ pixels, so when the scale factor is (say) 2, our drawing takes place at half size and then gets scaled up by the final blit in the draw event, making it look blurry and unpleasant. Secondly, those final blits seem to end up offset by half a pixel, so that a second blit over the same subrectangle doesn't _quite_ completely wipe out the previously blitted data - so there's a ghostly rectangle left behind everywhere the cursor has been. It's not that GTK doesn't _let_ you find out the scale factor; it's just that it's in an out-of-the-way piece of API that you have to call specially. So now we do: our backing surface is now created at a pixel resolution matching the screen's real pixels, and we translate GTK's scale factor into an ordinary cairo_scale() before we commence drawing. So we still end up drawing the same text at the same size - and this strategy also means that non-text elements like cursor outlines and underlining will be scaled up with the screen DPI rather than stubbornly staying one physical pixel thick - but now it's nice and sharp at full screen resolution, and the subrectangle blits in the draw event are back to affecting the exact set of pixels we expect them to. One silly consequence is that, immediately after removing the last one, I've installed a handler for the GTK "configure-event" signal! That's because the GTK 3 docs claim that that's how you get notified that your scale factor has changed at run time (e.g. if you reconfigure the scale factor of a whole monitor in the GNOME settings dialog). Actually in practice I seem to find out via the "draw" event before "configure" bothers to tell me, but now I've got a usefully idempotent function for 'check whether the scale factor has changed and sort it out if so', I don't see any harm in calling it from anywhere it _might_ be useful.

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

Use a Cairo image surface as a client-side cache. In any DRAWTYPE_CAIRO mode, we now do all our Cairo drawing to a Cairo image surface which lives on the client; then we either blit directly from that to the window (if we're in GTK3 mode, or GTK2 without deprecated pieces of API), or else we blit from the Cairo surface to the server-side pixmap and then from there to the actual window. In DRAWTYPE_GDK mode, nothing much has changed: we still draw directly to the server-side pixmap using the GDK drawing API, then blit from there to the window. But there is one change, namely that the blit is no longer done proactively - instead, we queue a redraw of the affected rectangle, and wait until we're called back by the expose handler. The main aim of all this is to arrange that the only time we ever draw to the real window is in response to expose/draw events. The experimental GTK3 OS X port stopped working a week or two ago (I presume in response to an OS update) with the symptoms that attempts to draw on the window outside the context of a "draw" event handler just didn't seem to work any more; this change fixes it. In addition to that benefit, this change also has obvious performance advantages in principle. No more expensive text rendering in response to an expose event - just re-copy to the window from the bitmap we already have, from wherever it's stored that's nearest. Moreover, this seems to have fixed the significant performance problem with X server-side fonts under GTK. I didn't expect _that_! I'd guessed that the approach of downloading character bitmaps and rendering them manually via Cairo was just inherently slow for some reason. I've no real idea _why_ this change improves matters so much; my best guess is that perhaps there's an overhead in each drawing operation to a GDK Cairo surface, so we win by doing lots of operations to a much faster image surface and then batching them up into one GDK Cairo operation. But whyever it is, I'm certainly not complaining! (In fact, it now seems to be noticeably _faster_, at least on my usual local X displays, to draw server-side fonts using that technique than using the old GDK approach. I may yet decide to switch over...)

Change Cairo image surface type from RGB24 to ARGB32. This seems to work around a GTK 3.22 display bug that Colin Watson and I have both observed on Ubuntu (though I found that proxying the X server, e.g. by SSH X forwarding or xtruss, inhibited the bug). The effect of the bug was that the terminal window would appear completely black and nothing would ever be displayed in it, though the terminal session was still actually running and keystrokes would be sent to it. But changing the call to cairo_set_source_surface() to some other cairo_set_source_foo caused successful drawing of whatever other source I selected; the problem seemed specific to the image surface. Also, when I popped up the Ctrl-right-click menu over the terminal window, the menu didn't disappear when dismissed, i.e. the drawing area's redraw operation was not drawing in black, but failing to draw _anything_. That led me to hypothesise that the draw event handler for the terminal drawing area might somehow be accidentally inventing 0 rather than 255 for the implicit alpha channel when using our RGB-type image surface as a source; so I tried setting the surface type to one with an explicit alpha channel in the hope that there would no longer be a need to make up any alpha value at all. And indeed, that seems to solve the problem for me, so I might as well commit it. However, I don't know the full details of what the previous problem was, so this is only an empirical workaround. If it turns out I was making some other mistake without which a RGB source surface would have worked for me, then I should probably revert this and do whatever other fix turns out to be a better plan.

Use a Cairo image surface as a client-side cache. In any DRAWTYPE_CAIRO mode, we now do all our Cairo drawing to a Cairo image surface which lives on the client; then we either blit directly from that to the window (if we're in GTK3 mode, or GTK2 without deprecated pieces of API), or else we blit from the Cairo surface to the server-side pixmap and then from there to the actual window. In DRAWTYPE_GDK mode, nothing much has changed: we still draw directly to the server-side pixmap using the GDK drawing API, then blit from there to the window. But there is one change, namely that the blit is no longer done proactively - instead, we queue a redraw of the affected rectangle, and wait until we're called back by the expose handler. The main aim of all this is to arrange that the only time we ever draw to the real window is in response to expose/draw events. The experimental GTK3 OS X port stopped working a week or two ago (I presume in response to an OS update) with the symptoms that attempts to draw on the window outside the context of a "draw" event handler just didn't seem to work any more; this change fixes it.

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

Stop using the GTK "configure-event" signal. I've been using that signal since the very first commit of this source file, as a combined way to be notified when the size of the drawing area changes (typically due to user window resizing actions) and also when the drawing area is first created and available to be drawn on. Unfortunately, testing on Ubuntu 18.04, I ran into an oddity, in which the call to gtk_widget_show(inst->window) in new_session_window() has the side effect of delivering a spurious configure_event on the drawing area with size 1x46 pixels. This causes the terminal to resize itself to 1 column wide, and the mistake isn't rectified until a followup configure-event arrives after new_session_window returns to the GTK main loop. But that means terminal output can occur between those two configure events (the connection-sharing "Reusing a shared connection to host.name" is a good example), and when it does, it gets embarrassingly wrapped at one character per line down the left column. I briefly tried to bodge around this by trying to heuristically guess which configure events were real and which were spurious, but I have no faith in that strategy continuing to work. I think a better approach is to abandon configure-event completely, and move to a system in which the two purposes I was using it for are handled by two _different_ GTK signals, namely "size-allocate" (for knowing when we get resized) and "realize" (for knowing when the drawing area physically exists for us to start setting up Cairo or GDK machinery). The result seems to have fixed the silly one-column wrapping bug, and retained the ability to handle window resizes, on every GTK version I have conveniently available to test on, including GTK 3 both before and after these spurious configures started to happen.

GTK 3: be aware of the window's scale factor. In GTK 3.10 and above, high-DPI support is arranged by each window having a property called a 'scale factor', which translates logical pixels as seen by most of the GTK API (widget and window sizes and positions, coordinates in the "draw" event, etc) into the physical pixels on the screen. This is handled more or less transparently, except that one side effect is that your Cairo-based drawing code had better be able to cope with that scaling without getting confused. PuTTY's isn't, because we do all our serious drawing on a separate Cairo surface we made ourselves, and then blit subrectangles of that to the window during updates. This has two bad consequences. Firstly, our surface has a size derived from what GTK told us the drawing area size is, i.e. corresponding to GTK's _logical_ pixels, so when the scale factor is (say) 2, our drawing takes place at half size and then gets scaled up by the final blit in the draw event, making it look blurry and unpleasant. Secondly, those final blits seem to end up offset by half a pixel, so that a second blit over the same subrectangle doesn't _quite_ completely wipe out the previously blitted data - so there's a ghostly rectangle left behind everywhere the cursor has been. It's not that GTK doesn't _let_ you find out the scale factor; it's just that it's in an out-of-the-way piece of API that you have to call specially. So now we do: our backing surface is now created at a pixel resolution matching the screen's real pixels, and we translate GTK's scale factor into an ordinary cairo_scale() before we commence drawing. So we still end up drawing the same text at the same size - and this strategy also means that non-text elements like cursor outlines and underlining will be scaled up with the screen DPI rather than stubbornly staying one physical pixel thick - but now it's nice and sharp at full screen resolution, and the subrectangle blits in the draw event are back to affecting the exact set of pixels we expect them to. One silly consequence is that, immediately after removing the last one, I've installed a handler for the GTK "configure-event" signal! That's because the GTK 3 docs claim that that's how you get notified that your scale factor has changed at run time (e.g. if you reconfigure the scale factor of a whole monitor in the GNOME settings dialog). Actually in practice I seem to find out via the "draw" event before "configure" bothers to tell me, but now I've got a usefully idempotent function for 'check whether the scale factor has changed and sort it out if so', I don't see any harm in calling it from anywhere it _might_ be useful.

Use a Cairo image surface as a client-side cache. In any DRAWTYPE_CAIRO mode, we now do all our Cairo drawing to a Cairo image surface which lives on the client; then we either blit directly from that to the window (if we're in GTK3 mode, or GTK2 without deprecated pieces of API), or else we blit from the Cairo surface to the server-side pixmap and then from there to the actual window. In DRAWTYPE_GDK mode, nothing much has changed: we still draw directly to the server-side pixmap using the GDK drawing API, then blit from there to the window. But there is one change, namely that the blit is no longer done proactively - instead, we queue a redraw of the affected rectangle, and wait until we're called back by the expose handler. The main aim of all this is to arrange that the only time we ever draw to the real window is in response to expose/draw events. The experimental GTK3 OS X port stopped working a week or two ago (I presume in response to an OS update) with the symptoms that attempts to draw on the window outside the context of a "draw" event handler just didn't seem to work any more; this change fixes it. In addition to that benefit, this change also has obvious performance advantages in principle. No more expensive text rendering in response to an expose event - just re-copy to the window from the bitmap we already have, from wherever it's stored that's nearest. Moreover, this seems to have fixed the significant performance problem with X server-side fonts under GTK. I didn't expect _that_! I'd guessed that the approach of downloading character bitmaps and rendering them manually via Cairo was just inherently slow for some reason. I've no real idea _why_ this change improves matters so much; my best guess is that perhaps there's an overhead in each drawing operation to a GDK Cairo surface, so we win by doing lots of operations to a much faster image surface and then batching them up into one GDK Cairo operation. But whyever it is, I'm certainly not complaining! (In fact, it now seems to be noticeably _faster_, at least on my usual local X displays, to draw server-side fonts using that technique than using the old GDK approach. I may yet decide to switch over...)

GTK 3: be aware of the window's scale factor. In GTK 3.10 and above, high-DPI support is arranged by each window having a property called a 'scale factor', which translates logical pixels as seen by most of the GTK API (widget and window sizes and positions, coordinates in the "draw" event, etc) into the physical pixels on the screen. This is handled more or less transparently, except that one side effect is that your Cairo-based drawing code had better be able to cope with that scaling without getting confused. PuTTY's isn't, because we do all our serious drawing on a separate Cairo surface we made ourselves, and then blit subrectangles of that to the window during updates. This has two bad consequences. Firstly, our surface has a size derived from what GTK told us the drawing area size is, i.e. corresponding to GTK's _logical_ pixels, so when the scale factor is (say) 2, our drawing takes place at half size and then gets scaled up by the final blit in the draw event, making it look blurry and unpleasant. Secondly, those final blits seem to end up offset by half a pixel, so that a second blit over the same subrectangle doesn't _quite_ completely wipe out the previously blitted data - so there's a ghostly rectangle left behind everywhere the cursor has been. It's not that GTK doesn't _let_ you find out the scale factor; it's just that it's in an out-of-the-way piece of API that you have to call specially. So now we do: our backing surface is now created at a pixel resolution matching the screen's real pixels, and we translate GTK's scale factor into an ordinary cairo_scale() before we commence drawing. So we still end up drawing the same text at the same size - and this strategy also means that non-text elements like cursor outlines and underlining will be scaled up with the screen DPI rather than stubbornly staying one physical pixel thick - but now it's nice and sharp at full screen resolution, and the subrectangle blits in the draw event are back to affecting the exact set of pixels we expect them to. One silly consequence is that, immediately after removing the last one, I've installed a handler for the GTK "configure-event" signal! That's because the GTK 3 docs claim that that's how you get notified that your scale factor has changed at run time (e.g. if you reconfigure the scale factor of a whole monitor in the GNOME settings dialog). Actually in practice I seem to find out via the "draw" event before "configure" bothers to tell me, but now I've got a usefully idempotent function for 'check whether the scale factor has changed and sort it out if so', I don't see any harm in calling it from anywhere it _might_ be useful.

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

Initial support for clipboard on OS X. Rather than trying to get my existing hugely complicated X-style clipboard code to somehow work with the Quartz GTK back end, I've written an entirely new and much simpler alternative clipboard handler usnig the higher-leve GtkClipboard interface. It assumes all clipboard text can be converted to and from UTF-8 sensibly (which isn't a good assumption on all front ends, but on OS X I think it's reasonable), and it talks to GDK_SELECTION_CLIPBOARD rather than PRIMARY, which is the only clipboard OS X has. I had to do a fiddly thing to cope with the fact that each call to gtk_clipboard_set_with_data caused a call to the clipboard clear function left over from the previous set of data, so I had to avoid mistaking that for a clipboard-clear for the _new_ data and immediately deselecting it. I did that by allocating a distinct placeholder object in memory for each instance of the copy operation, so that I can tell whether a clipboard-clear is for the current copy or a previous one. This is only very basic support which demonstrates successful copying and pasting is at least possible. For a sensible OS X implementation we'll need a more believable means of generating a paste UI action (it's quite easy to find a Mac on which neither Shift-Ins nor the third mouse button even exists!). Also, after the trouble I had with the clipboard-clear event, it's a bit annoying to find that it _doesn't_ seem to get called when another application becomes the clipboard owner. That may just be something we have to put up with, if I can't find any reason why it's failing.

Initial support for clipboard on OS X. Rather than trying to get my existing hugely complicated X-style clipboard code to somehow work with the Quartz GTK back end, I've written an entirely new and much simpler alternative clipboard handler usnig the higher-leve GtkClipboard interface. It assumes all clipboard text can be converted to and from UTF-8 sensibly (which isn't a good assumption on all front ends, but on OS X I think it's reasonable), and it talks to GDK_SELECTION_CLIPBOARD rather than PRIMARY, which is the only clipboard OS X has. I had to do a fiddly thing to cope with the fact that each call to gtk_clipboard_set_with_data caused a call to the clipboard clear function left over from the previous set of data, so I had to avoid mistaking that for a clipboard-clear for the _new_ data and immediately deselecting it. I did that by allocating a distinct placeholder object in memory for each instance of the copy operation, so that I can tell whether a clipboard-clear is for the current copy or a previous one. This is only very basic support which demonstrates successful copying and pasting is at least possible. For a sensible OS X implementation we'll need a more believable means of generating a paste UI action (it's quite easy to find a Mac on which neither Shift-Ins nor the third mouse button even exists!). Also, after the trouble I had with the clipboard-clear event, it's a bit annoying to find that it _doesn't_ seem to get called when another application becomes the clipboard owner.

Basic support for running under GDK Wayland back end. GTK 3 PuTTY/pterm has always assumed that if it was compiled with _support_ for talking to the raw X11 layer underneath GTK and GDK, then it was entitled to expect that raw X11 layer to exist at all times, i.e. that GDK_DISPLAY_XDISPLAY would return a meaningful X display that it could do useful things with. So if you ran it over the GDK Wayland backend, it would immediately segfault. Modern GTK applications need to cope with multiple GDK backends at run time. It's fine for GTK PuTTY to _contain_ the code to find and use underlying X11 primitives like the display and the X window id, but it should be prepared to find that it's running on Wayland (or something else again!) so those functions don't return anything useful - in which case it should degrade gracefully to the subset of functionality that can be accessed through backend-independent GTK calls. Accordingly, I've centralised the use of GDK_DISPLAY_XDISPLAY into a support function get_x_display() in gtkmisc.c, which starts by checking that there actually is one first. All previous direct uses of GDK_*_XDISPLAY now go via that function, and check the result for NULL afterwards. (To save faffing about calling that function too many times, I'm also caching the display pointer in more places, and passing it as an extra argument to various subfunctions, mostly in gtkfont.c.) Similarly, the get_windowid() function that retrieves the window id to put in the environment of pterm's child process has to be prepared for there not to be a window id. This isn't a complete fix for all Wayland-related problems. The other one I'm currently aware of is that the default font is "server:fixed", which is a bad default now that it won't be available on all backends. And I expect that further problems will show up with more testing. But it's a start.

Initial support for clipboard on OS X. Rather than trying to get my existing hugely complicated X-style clipboard code to somehow work with the Quartz GTK back end, I've written an entirely new and much simpler alternative clipboard handler usnig the higher-leve GtkClipboard interface. It assumes all clipboard text can be converted to and from UTF-8 sensibly (which isn't a good assumption on all front ends, but on OS X I think it's reasonable), and it talks to GDK_SELECTION_CLIPBOARD rather than PRIMARY, which is the only clipboard OS X has. I had to do a fiddly thing to cope with the fact that each call to gtk_clipboard_set_with_data caused a call to the clipboard clear function left over from the previous set of data, so I had to avoid mistaking that for a clipboard-clear for the _new_ data and immediately deselecting it. I did that by allocating a distinct placeholder object in memory for each instance of the copy operation, so that I can tell whether a clipboard-clear is for the current copy or a previous one. This is only very basic support which demonstrates successful copying and pasting is at least possible. For a sensible OS X implementation we'll need a more believable means of generating a paste UI action (it's quite easy to find a Mac on which neither Shift-Ins nor the third mouse button even exists!). Also, after the trouble I had with the clipboard-clear event, it's a bit annoying to find that it _doesn't_ seem to get called when another application becomes the clipboard owner. That may just be something we have to put up with, if I can't find any reason why it's failing.

Initial support for clipboard on OS X. Rather than trying to get my existing hugely complicated X-style clipboard code to somehow work with the Quartz GTK back end, I've written an entirely new and much simpler alternative clipboard handler usnig the higher-leve GtkClipboard interface. It assumes all clipboard text can be converted to and from UTF-8 sensibly (which isn't a good assumption on all front ends, but on OS X I think it's reasonable), and it talks to GDK_SELECTION_CLIPBOARD rather than PRIMARY, which is the only clipboard OS X has. I had to do a fiddly thing to cope with the fact that each call to gtk_clipboard_set_with_data caused a call to the clipboard clear function left over from the previous set of data, so I had to avoid mistaking that for a clipboard-clear for the _new_ data and immediately deselecting it. I did that by allocating a distinct placeholder object in memory for each instance of the copy operation, so that I can tell whether a clipboard-clear is for the current copy or a previous one. This is only very basic support which demonstrates successful copying and pasting is at least possible. For a sensible OS X implementation we'll need a more believable means of generating a paste UI action (it's quite easy to find a Mac on which neither Shift-Ins nor the third mouse button even exists!). Also, after the trouble I had with the clipboard-clear event, it's a bit annoying to find that it _doesn't_ seem to get called when another application becomes the clipboard owner. That may just be something we have to put up with, if I can't find any reason why it's failing.

Basic support for running under GDK Wayland back end. GTK 3 PuTTY/pterm has always assumed that if it was compiled with _support_ for talking to the raw X11 layer underneath GTK and GDK, then it was entitled to expect that raw X11 layer to exist at all times, i.e. that GDK_DISPLAY_XDISPLAY would return a meaningful X display that it could do useful things with. So if you ran it over the GDK Wayland backend, it would immediately segfault. Modern GTK applications need to cope with multiple GDK backends at run time. It's fine for GTK PuTTY to _contain_ the code to find and use underlying X11 primitives like the display and the X window id, but it should be prepared to find that it's running on Wayland (or something else again!) so those functions don't return anything useful - in which case it should degrade gracefully to the subset of functionality that can be accessed through backend-independent GTK calls. Accordingly, I've centralised the use of GDK_DISPLAY_XDISPLAY into a support function get_x_display() in gtkmisc.c, which starts by checking that there actually is one first. All previous direct uses of GDK_*_XDISPLAY now go via that function, and check the result for NULL afterwards. (To save faffing about calling that function too many times, I'm also caching the display pointer in more places, and passing it as an extra argument to various subfunctions, mostly in gtkfont.c.) Similarly, the get_windowid() function that retrieves the window id to put in the environment of pterm's child process has to be prepared for there not to be a window id. This isn't a complete fix for all Wayland-related problems. The other one I'm currently aware of is that the default font is "server:fixed", which is a bad default now that it won't be available on all backends. And I expect that further problems will show up with more testing. But it's a start.

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

Refactor the GTK drawing system to do both GDK and Cairo. We're going to have to use Cairo in the GTK3 port, because that's all GTK3 supports; but we still need old-style GDK for GTK1 support, and also for performance reasons in GTK2 (see below). Hence, this change completely restructures GTK PuTTY's drawing code so that there's a central 'drawing context' structure which contains a type code indicating GDK or Cairo, and then either some GDK gubbins or some Cairo gubbins as appropriate; all actual drawing is abstracted through a set of routines which test the type code in that structure and do one thing or another. And because the type code is tested at run time, both sets of drawing primitives can be compiled in at once, and where possible, they will be. X server-side bitmap fonts are still supported in the Cairo world, but because Cairo drawing is entirely client-side, they have to work by cheekily downloading each glyph bitmap from the server when it's first needed, and building up a client-side cache of 'cairo_surface_t's containing the bitmaps with which we then draw on the window. This technique works, but it's rather slow; hence, even in GTK2, we keep the GDK drawing back end compiled in, and switch over to it when the main selected font is a bitmap one. One visible effect of the new Cairo routines is in the double-width and double-height text you can get by sending ESC # 3, ESC # 4 and ESC # 6 escape sequences. In GDK, that's always been done by a really horrible process of manually scaling the bitmap, server-side, column by column and row by row, causing each pixel to be exactly doubled or quadrupled. But in Cairo, we can just set a transformation matrix, and then that takes effect _before_ the scalable fonts are rendered - so the results are visibly nicer, and use all the available resolution. (Sadly, if you're using a server-side bitmap font as your primary one, then the GDK backend will be selected for all drawing in the terminal as a whole - so in that situation, even fallback characters absent from the primary font and rendered by Pango will get the old GDK scaling treatment. It's only if your main font is scalable, so that the Cairo backend is selected, that DW/DH characters will come out looking nice.)

I've no real idea _why_ this change improves matters so much; my best guess is that perhaps there's an overhead in each drawing operation to a GDK Cairo surface, so we win by doing lots of operations to a much faster image surface and then batching them up into one GDK Cairo operation. But whyever it is, I'm certainly not complaining! (In fact, it now seems to be noticeably _faster_, at least on my usual local X displays, to draw server-side fonts using that technique than using the old GDK approach.

GTK 3: be aware of the window's scale factor. In GTK 3.10 and above, high-DPI support is arranged by each window having a property called a 'scale factor', which translates logical pixels as seen by most of the GTK API (widget and window sizes and positions, coordinates in the "draw" event, etc) into the physical pixels on the screen. This is handled more or less transparently, except that one side effect is that your Cairo-based drawing code had better be able to cope with that scaling without getting confused. PuTTY's isn't, because we do all our serious drawing on a separate Cairo surface we made ourselves, and then blit subrectangles of that to the window during updates. This has two bad consequences. Firstly, our surface has a size derived from what GTK told us the drawing area size is, i.e. corresponding to GTK's _logical_ pixels, so when the scale factor is (say) 2, our drawing takes place at half size and then gets scaled up by the final blit in the draw event, making it look blurry and unpleasant. Secondly, those final blits seem to end up offset by half a pixel, so that a second blit over the same subrectangle doesn't _quite_ completely wipe out the previously blitted data - so there's a ghostly rectangle left behind everywhere the cursor has been. It's not that GTK doesn't _let_ you find out the scale factor; it's just that it's in an out-of-the-way piece of API that you have to call specially. So now we do: our backing surface is now created at a pixel resolution matching the screen's real pixels, and we translate GTK's scale factor into an ordinary cairo_scale() before we commence drawing. So we still end up drawing the same text at the same size - and this strategy also means that non-text elements like cursor outlines and underlining will be scaled up with the screen DPI rather than stubbornly staying one physical pixel thick - but now it's nice and sharp at full screen resolution, and the subrectangle blits in the draw event are back to affecting the exact set of pixels we expect them to. One silly consequence is that, immediately after removing the last one, I've installed a handler for the GTK "configure-event" signal! That's because the GTK 3 docs claim that that's how you get notified that your scale factor has changed at run time (e.g. if you reconfigure the scale factor of a whole monitor in the GNOME settings dialog). Actually in practice I seem to find out via the "draw" event before "configure" bothers to tell me, but now I've got a usefully idempotent function for 'check whether the scale factor has changed and sort it out if so', I don't see any harm in calling it from anywhere it _might_ be useful.

Use a Cairo image surface as a client-side cache. In any DRAWTYPE_CAIRO mode, we now do all our Cairo drawing to a Cairo image surface which lives on the client; then we either blit directly from that to the window (if we're in GTK3 mode, or GTK2 without deprecated pieces of API), or else we blit from the Cairo surface to the server-side pixmap and then from there to the actual window. In DRAWTYPE_GDK mode, nothing much has changed: we still draw directly to the server-side pixmap using the GDK drawing API, then blit from there to the window. But there is one change, namely that the blit is no longer done proactively - instead, we queue a redraw of the affected rectangle, and wait until we're called back by the expose handler. The main aim of all this is to arrange that the only time we ever draw to the real window is in response to expose/draw events. The experimental GTK3 OS X port stopped working a week or two ago (I presume in response to an OS update) with the symptoms that attempts to draw on the window outside the context of a "draw" event handler just didn't seem to work any more; this change fixes it. In addition to that benefit, this change also has obvious performance advantages in principle. No more expensive text rendering in response to an expose event - just re-copy to the window from the bitmap we already have, from wherever it's stored that's nearest. Moreover, this seems to have fixed the significant performance problem with X server-side fonts under GTK. I didn't expect _that_! I'd guessed that the approach of downloading character bitmaps and rendering them manually via Cairo was just inherently slow for some reason. I've no real idea _why_ this change improves matters so much; my best guess is that perhaps there's an overhead in each drawing operation to a GDK Cairo surface, so we win by doing lots of operations to a much faster image surface and then batching them up into one GDK Cairo operation. But whyever it is, I'm certainly not complaining! (In fact, it now seems to be noticeably _faster_, at least on my usual local X displays, to draw server-side fonts using that technique than using the old GDK approach. I may yet decide to switch over...)

And because the type code is tested at run time, both sets of drawing primitives can be compiled in at once, and where possible, they will be. X server-side bitmap fonts are still supported in the Cairo world, but because Cairo drawing is entirely client-side, they have to work by cheekily downloading each glyph bitmap from the server when it's first needed, and building up a client-side cache of 'cairo_surface_t's containing the bitmaps with which we then draw on the window. This technique works, but it's rather slow; hence, even in GTK2, we keep the GDK drawing back end compiled in, and switch over to it when the main selected font is a bitmap one. One visible effect of the new Cairo routines is in the double-width and double-height text you can get by sending ESC # 3, ESC # 4 and ESC # 6 escape sequences. In GDK, that's always been done by a really horrible process of manually scaling the bitmap, server-side, column by column and row by row, causing each pixel to be exactly doubled or quadrupled. But in Cairo, we can just set a transformation matrix, and then that takes effect _before_ the scalable fonts are rendered - so the results are visibly nicer, and use all the available resolution. (Sadly, if you're using a server-side bitmap font as your primary one, then the GDK backend will be selected for all drawing in the terminal as a whole - so in that situation, even fallback characters absent from the primary font and rendered by Pango will get the old GDK scaling treatment.

We're going to have to use Cairo in the GTK3 port, because that's all GTK3 supports; but we still need old-style GDK for GTK1 support, and also for performance reasons in GTK2 (see below). Hence, this change completely restructures GTK PuTTY's drawing code so that there's a central 'drawing context' structure which contains a type code indicating GDK or Cairo, and then either some GDK gubbins or some Cairo gubbins as appropriate; all actual drawing is abstracted through a set of routines which test the type code in that structure and do one thing or another. And because the type code is tested at run time, both sets of drawing primitives can be compiled in at once, and where possible, they will be. X server-side bitmap fonts are still supported in the Cairo world, but because Cairo drawing is entirely client-side, they have to work by cheekily downloading each glyph bitmap from the server when it's first needed, and building up a client-side cache of 'cairo_surface_t's containing the bitmaps with which we then draw on the window. This technique works, but it's rather slow; hence, even in GTK2, we keep the GDK drawing back end compiled in, and switch over to it when the main selected font is a bitmap one. One visible effect of the new Cairo routines is in the double-width and double-height text you can get by sending ESC # 3, ESC # 4 and ESC # 6 escape sequences. In GDK, that's always been done by a really horrible process of manually scaling the bitmap, server-side, column by column and row by row, causing each pixel to be exactly doubled or quadrupled. But in Cairo, we can just set a transformation matrix, and then that takes effect _before_ the scalable fonts are rendered - so the results are visibly nicer, and use all the available resolution. (Sadly, if you're using a server-side bitmap font as your primary one, then the GDK backend will be selected for all drawing in the terminal as a whole - so in that situation, even fallback characters absent from the primary font and rendered by Pango will get the old GDK scaling treatment. It's only if your main font is scalable, so that the Cairo backend is selected, that DW/DH characters will come out looking nice.)

Stop using the GTK "configure-event" signal. I've been using that signal since the very first commit of this source file, as a combined way to be notified when the size of the drawing area changes (typically due to user window resizing actions) and also when the drawing area is first created and available to be drawn on. Unfortunately, testing on Ubuntu 18.04, I ran into an oddity, in which the call to gtk_widget_show(inst->window) in new_session_window() has the side effect of delivering a spurious configure_event on the drawing area with size 1x46 pixels. This causes the terminal to resize itself to 1 column wide, and the mistake isn't rectified until a followup configure-event arrives after new_session_window returns to the GTK main loop. But that means terminal output can occur between those two configure events (the connection-sharing "Reusing a shared connection to host.name" is a good example), and when it does, it gets embarrassingly wrapped at one character per line down the left column. I briefly tried to bodge around this by trying to heuristically guess which configure events were real and which were spurious, but I have no faith in that strategy continuing to work. I think a better approach is to abandon configure-event completely, and move to a system in which the two purposes I was using it for are handled by two _different_ GTK signals, namely "size-allocate" (for knowing when we get resized) and "realize" (for knowing when the drawing area physically exists for us to start setting up Cairo or GDK machinery). The result seems to have fixed the silly one-column wrapping bug, and retained the ability to handle window resizes, on every GTK version I have conveniently available to test on, including GTK 3 both before and after these spurious configures started to happen.

Use a Cairo image surface as a client-side cache. In any DRAWTYPE_CAIRO mode, we now do all our Cairo drawing to a Cairo image surface which lives on the client; then we either blit directly from that to the window (if we're in GTK3 mode, or GTK2 without deprecated pieces of API), or else we blit from the Cairo surface to the server-side pixmap and then from there to the actual window. In DRAWTYPE_GDK mode, nothing much has changed: we still draw directly to the server-side pixmap using the GDK drawing API, then blit from there to the window. But there is one change, namely that the blit is no longer done proactively - instead, we queue a redraw of the affected rectangle, and wait until we're called back by the expose handler. The main aim of all this is to arrange that the only time we ever draw to the real window is in response to expose/draw events. The experimental GTK3 OS X port stopped working a week or two ago (I presume in response to an OS update) with the symptoms that attempts to draw on the window outside the context of a "draw" event handler just didn't seem to work any more; this change fixes it. In addition to that benefit, this change also has obvious performance advantages in principle. No more expensive text rendering in response to an expose event - just re-copy to the window from the bitmap we already have, from wherever it's stored that's nearest. Moreover, this seems to have fixed the significant performance problem with X server-side fonts under GTK. I didn't expect _that_! I'd guessed that the approach of downloading character bitmaps and rendering them manually via Cairo was just inherently slow for some reason. I've no real idea _why_ this change improves matters so much; my best guess is that perhaps there's an overhead in each drawing operation to a GDK Cairo surface, so we win by doing lots of operations to a much faster image surface and then batching them up into one GDK Cairo operation. But whyever it is, I'm certainly not complaining! (In fact, it now seems to be noticeably _faster_, at least on my usual local X displays, to draw server-side fonts using that technique than using the old GDK approach. I may yet decide to switch over...)

Re-engineering of terminal emulator, phase 1. The active terminal screen is no longer an array of `unsigned long' encoding 16-bit Unicode plus 16 attribute bits. Now it's an array of `termchar' structures, which currently have 32-bit Unicode and 32 attribute bits but which will probably expand further in future. To prevent bloat of the memory footprint, I've introduced a mostly RLE-like compression scheme for storing scrollback: each line is compressed into a compact (but hard to modify) form when it moves into the term->scrollback tree, and is temporarily decompressed when the user wants to scroll back over it. My initial tests suggest that this compression averages about 1/4 of the previous (32 bits per character cell) data size in typical output, which means this is an improvement even without counting the new ability to extend the information stored in each character cell. Another beneficial side effect is that the insane format in which Unicode was passed to front ends through do_text() has now been rendered sane. Testing is incomplete; this _may_ still have instabilities. Windows and Unix front ends both seem to work as far as I've looked, but I haven't yet looked very hard. The Mac front end I've edited (it seemed obvious how to change it) but I can't compile or test it. As an immediate functional effect, the terminal emulator now supports full 32-bit Unicode to whatever extent the host platform allows it to. For example, if you output a 4-or-more-byte UTF-8 character in Unix pterm, it will not display it properly, but it will correctly paste it back out in a UTF8_STRING selection. Windows is more restricted, sadly. [originally from svn r4609]

Hence, this change completely restructures GTK PuTTY's drawing code so that there's a central 'drawing context' structure which contains a type code indicating GDK or Cairo, and then either some GDK gubbins or some Cairo gubbins as appropriate; all actual drawing is abstracted through a set of routines which test the type code in that structure and do one thing or another. And because the type code is tested at run time, both sets of drawing primitives can be compiled in at once, and where possible, they will be. X server-side bitmap fonts are still supported in the Cairo world, but because Cairo drawing is entirely client-side, they have to work by cheekily downloading each glyph bitmap from the server when it's first needed, and building up a client-side cache of 'cairo_surface_t's containing the bitmaps with which we then draw on the window. This technique works, but it's rather slow; hence, even in GTK2, we keep the GDK drawing back end compiled in, and switch over to it when the main selected font is a bitmap one. One visible effect of the new Cairo routines is in the double-width and double-height text you can get by sending ESC # 3, ESC # 4 and ESC # 6 escape sequences. In GDK, that's always been done by a really horrible process of manually scaling the bitmap, server-side, column by column and row by row, causing each pixel to be exactly doubled or quadrupled. But in Cairo, we can just set a transformation matrix, and then that takes effect _before_ the scalable fonts are rendered - so the results are visibly nicer, and use all the available resolution. (Sadly, if you're using a server-side bitmap font as your primary one, then the GDK backend will be selected for all drawing in the terminal as a whole - so in that situation, even fallback characters absent from the primary font and rendered by Pango will get the old GDK scaling treatment. It's only if your main font is scalable, so that the Cairo backend is selected, that DW/DH characters will come out looking nice.)

Re-engineering of terminal emulator, phase 1. The active terminal screen is no longer an array of `unsigned long' encoding 16-bit Unicode plus 16 attribute bits. Now it's an array of `termchar' structures, which currently have 32-bit Unicode and 32 attribute bits but which will probably expand further in future. To prevent bloat of the memory footprint, I've introduced a mostly RLE-like compression scheme for storing scrollback: each line is compressed into a compact (but hard to modify) form when it moves into the term->scrollback tree, and is temporarily decompressed when the user wants to scroll back over it. My initial tests suggest that this compression averages about 1/4 of the previous (32 bits per character cell) data size in typical output, which means this is an improvement even without counting the new ability to extend the information stored in each character cell. Another beneficial side effect is that the insane format in which Unicode was passed to front ends through do_text() has now been rendered sane. Testing is incomplete; this _may_ still have instabilities. Windows and Unix front ends both seem to work as far as I've looked, but I haven't yet looked very hard. The Mac front end I've edited (it seemed obvious how to change it) but I can't compile or test it. As an immediate functional effect, the terminal emulator now supports full 32-bit Unicode to whatever extent the host platform allows it to. For example, if you output a 4-or-more-byte UTF-8 character in Unix pterm, it will not display it properly, but it will correctly paste it back out in a UTF8_STRING selection. Windows is more restricted, sadly. [originally from svn r4609]

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place).

When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session.

Refactor the GTK drawing system to do both GDK and Cairo. We're going to have to use Cairo in the GTK3 port, because that's all GTK3 supports; but we still need old-style GDK for GTK1 support, and also for performance reasons in GTK2 (see below). Hence, this change completely restructures GTK PuTTY's drawing code so that there's a central 'drawing context' structure which contains a type code indicating GDK or Cairo, and then either some GDK gubbins or some Cairo gubbins as appropriate; all actual drawing is abstracted through a set of routines which test the type code in that structure and do one thing or another. And because the type code is tested at run time, both sets of drawing primitives can be compiled in at once, and where possible, they will be. X server-side bitmap fonts are still supported in the Cairo world, but because Cairo drawing is entirely client-side, they have to work by cheekily downloading each glyph bitmap from the server when it's first needed, and building up a client-side cache of 'cairo_surface_t's containing the bitmaps with which we then draw on the window. This technique works, but it's rather slow; hence, even in GTK2, we keep the GDK drawing back end compiled in, and switch over to it when the main selected font is a bitmap one. One visible effect of the new Cairo routines is in the double-width and double-height text you can get by sending ESC # 3, ESC # 4 and ESC # 6 escape sequences. In GDK, that's always been done by a really horrible process of manually scaling the bitmap, server-side, column by column and row by row, causing each pixel to be exactly doubled or quadrupled. But in Cairo, we can just set a transformation matrix, and then that takes effect _before_ the scalable fonts are rendered - so the results are visibly nicer, and use all the available resolution. (Sadly, if you're using a server-side bitmap font as your primary one, then the GDK backend will be selected for all drawing in the terminal as a whole - so in that situation, even fallback characters absent from the primary font and rendered by Pango will get the old GDK scaling treatment. It's only if your main font is scalable, so that the Cairo backend is selected, that DW/DH characters will come out looking nice.)

Basic support for running under GDK Wayland back end. GTK 3 PuTTY/pterm has always assumed that if it was compiled with _support_ for talking to the raw X11 layer underneath GTK and GDK, then it was entitled to expect that raw X11 layer to exist at all times, i.e. that GDK_DISPLAY_XDISPLAY would return a meaningful X display that it could do useful things with. So if you ran it over the GDK Wayland backend, it would immediately segfault. Modern GTK applications need to cope with multiple GDK backends at run time. It's fine for GTK PuTTY to _contain_ the code to find and use underlying X11 primitives like the display and the X window id, but it should be prepared to find that it's running on Wayland (or something else again!) so those functions don't return anything useful - in which case it should degrade gracefully to the subset of functionality that can be accessed through backend-independent GTK calls. Accordingly, I've centralised the use of GDK_DISPLAY_XDISPLAY into a support function get_x_display() in gtkmisc.c, which starts by checking that there actually is one first. All previous direct uses of GDK_*_XDISPLAY now go via that function, and check the result for NULL afterwards. (To save faffing about calling that function too many times, I'm also caching the display pointer in more places, and passing it as an extra argument to various subfunctions, mostly in gtkfont.c.) Similarly, the get_windowid() function that retrieves the window id to put in the environment of pterm's child process has to be prepared for there not to be a window id. This isn't a complete fix for all Wayland-related problems. The other one I'm currently aware of is that the default font is "server:fixed", which is a bad default now that it won't be available on all backends. And I expect that further problems will show up with more testing. But it's a start.

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

Refactor the GTK drawing system to do both GDK and Cairo. We're going to have to use Cairo in the GTK3 port, because that's all GTK3 supports; but we still need old-style GDK for GTK1 support, and also for performance reasons in GTK2 (see below). Hence, this change completely restructures GTK PuTTY's drawing code so that there's a central 'drawing context' structure which contains a type code indicating GDK or Cairo, and then either some GDK gubbins or some Cairo gubbins as appropriate; all actual drawing is abstracted through a set of routines which test the type code in that structure and do one thing or another. And because the type code is tested at run time, both sets of drawing primitives can be compiled in at once, and where possible, they will be. X server-side bitmap fonts are still supported in the Cairo world, but because Cairo drawing is entirely client-side, they have to work by cheekily downloading each glyph bitmap from the server when it's first needed, and building up a client-side cache of 'cairo_surface_t's containing the bitmaps with which we then draw on the window. This technique works, but it's rather slow; hence, even in GTK2, we keep the GDK drawing back end compiled in, and switch over to it when the main selected font is a bitmap one. One visible effect of the new Cairo routines is in the double-width and double-height text you can get by sending ESC # 3, ESC # 4 and ESC # 6 escape sequences. In GDK, that's always been done by a really horrible process of manually scaling the bitmap, server-side, column by column and row by row, causing each pixel to be exactly doubled or quadrupled. But in Cairo, we can just set a transformation matrix, and then that takes effect _before_ the scalable fonts are rendered - so the results are visibly nicer, and use all the available resolution. (Sadly, if you're using a server-side bitmap font as your primary one, then the GDK backend will be selected for all drawing in the terminal as a whole - so in that situation, even fallback characters absent from the primary font and rendered by Pango will get the old GDK scaling treatment. It's only if your main font is scalable, so that the Cairo backend is selected, that DW/DH characters will come out looking nice.)

When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.

Divide the whole of gtkwin.c into three parts. This lays further groundwork for the OS X GTK3 port, which is going to have to deal with multiple sessions sharing the same process. gtkwin.c was a bit too monolithic for this, since it included some process-global runtime state (timers, toplevel callbacks), some process startup stuff (gtk_init, gtk_main, argv processing) and some per-session-window stuff. The per-session stuff remains in gtkwin.c, with the top-level function now being new_session_window() taking a Conf. The new gtkmain.c contains the outer skeleton of pt_main(), handling argv processing and one-off startup stuff like setlocale; and the new gtkcomm.c contains the pieces of PuTTY infrastructure like timers and uxsel that are shared between multiple sessions rather than reinstantiated per session, which have been rewritten to use global variables rather than fields in 'inst' (since it's now clear to me that they'll have to apply to all the insts in existence at once). There are still some lurking assumptions of one-session-per-process, e.g. the use of gtk_main_quit when a session finishes, and the fact that the config box insists on running as a separate invocation of gtk_main so that one session's preliminary config box can't coexist with another session already active. But this should make it possible to at least write an OS X app good enough to start testing with, even if it doesn't get everything quite right yet. This change is almost entirely rearranging existing code, so it shouldn't be seriously destabilising. But two noticeable actual changes have happened, both pleasantly simplifying: Firstly, the global-variables rewrite of gtkcomm.c has allowed the post_main edifice to become a great deal simpler. Most of its complexity was about remembering what 'inst' it had to call back to, and in fact the right answer is that it shouldn't be calling back to one at all. So now the post_main() called by gtkdlg.c has become the same function as the old inst_post_main() that actually did the work, instead of the two having to be connected by a piece of ugly plumbing. Secondly, a piece of code that's vanished completely in this refactoring is the temporary blocking of SIGCHLD around most of the session setup code. This turns out to have been introduced in 2002, _before_ I switched to using the intra-process signal pipe strategy for SIGCHLD handling in 2003. So I now expect that we should be robust in any case against receiving SIGCHLD at an inconvenient moment, and hence there's no need to block it.

Divide the whole of gtkwin.c into three parts. This lays further groundwork for the OS X GTK3 port, which is going to have to deal with multiple sessions sharing the same process. gtkwin.c was a bit too monolithic for this, since it included some process-global runtime state (timers, toplevel callbacks), some process startup stuff (gtk_init, gtk_main, argv processing) and some per-session-window stuff. The per-session stuff remains in gtkwin.c, with the top-level function now being new_session_window() taking a Conf. The new gtkmain.c contains the outer skeleton of pt_main(), handling argv processing and one-off startup stuff like setlocale; and the new gtkcomm.c contains the pieces of PuTTY infrastructure like timers and uxsel that are shared between multiple sessions rather than reinstantiated per session, which have been rewritten to use global variables rather than fields in 'inst' (since it's now clear to me that they'll have to apply to all the insts in existence at once). There are still some lurking assumptions of one-session-per-process, e.g. the use of gtk_main_quit when a session finishes, and the fact that the config box insists on running as a separate invocation of gtk_main so that one session's preliminary config box can't coexist with another session already active. But this should make it possible to at least write an OS X app good enough to start testing with, even if it doesn't get everything quite right yet. This change is almost entirely rearranging existing code, so it shouldn't be seriously destabilising. But two noticeable actual changes have happened, both pleasantly simplifying: Firstly, the global-variables rewrite of gtkcomm.c has allowed the post_main edifice to become a great deal simpler. Most of its complexity was about remembering what 'inst' it had to call back to, and in fact the right answer is that it shouldn't be calling back to one at all. So now the post_main() called by gtkdlg.c has become the same function as the old inst_post_main() that actually did the work, instead of the two having to be connected by a piece of ugly plumbing. Secondly, a piece of code that's vanished completely in this refactoring is the temporary blocking of SIGCHLD around most of the session setup code. This turns out to have been introduced in 2002, _before_ I switched to using the intra-process signal pipe strategy for SIGCHLD handling in 2003. So I now expect that we should be robust in any case against receiving SIGCHLD at an inconvenient moment, and hence there's no need to block it.

Refactor the GTK drawing system to do both GDK and Cairo. We're going to have to use Cairo in the GTK3 port, because that's all GTK3 supports; but we still need old-style GDK for GTK1 support, and also for performance reasons in GTK2 (see below). Hence, this change completely restructures GTK PuTTY's drawing code so that there's a central 'drawing context' structure which contains a type code indicating GDK or Cairo, and then either some GDK gubbins or some Cairo gubbins as appropriate; all actual drawing is abstracted through a set of routines which test the type code in that structure and do one thing or another. And because the type code is tested at run time, both sets of drawing primitives can be compiled in at once, and where possible, they will be. X server-side bitmap fonts are still supported in the Cairo world, but because Cairo drawing is entirely client-side, they have to work by cheekily downloading each glyph bitmap from the server when it's first needed, and building up a client-side cache of 'cairo_surface_t's containing the bitmaps with which we then draw on the window. This technique works, but it's rather slow; hence, even in GTK2, we keep the GDK drawing back end compiled in, and switch over to it when the main selected font is a bitmap one. One visible effect of the new Cairo routines is in the double-width and double-height text you can get by sending ESC # 3, ESC # 4 and ESC # 6 escape sequences. In GDK, that's always been done by a really horrible process of manually scaling the bitmap, server-side, column by column and row by row, causing each pixel to be exactly doubled or quadrupled. But in Cairo, we can just set a transformation matrix, and then that takes effect _before_ the scalable fonts are rendered - so the results are visibly nicer, and use all the available resolution. (Sadly, if you're using a server-side bitmap font as your primary one, then the GDK backend will be selected for all drawing in the terminal as a whole - so in that situation, even fallback characters absent from the primary font and rendered by Pango will get the old GDK scaling treatment. It's only if your main font is scalable, so that the Cairo backend is selected, that DW/DH characters will come out looking nice.)

Basic support for running under GDK Wayland back end. GTK 3 PuTTY/pterm has always assumed that if it was compiled with _support_ for talking to the raw X11 layer underneath GTK and GDK, then it was entitled to expect that raw X11 layer to exist at all times, i.e. that GDK_DISPLAY_XDISPLAY would return a meaningful X display that it could do useful things with. So if you ran it over the GDK Wayland backend, it would immediately segfault. Modern GTK applications need to cope with multiple GDK backends at run time. It's fine for GTK PuTTY to _contain_ the code to find and use underlying X11 primitives like the display and the X window id, but it should be prepared to find that it's running on Wayland (or something else again!) so those functions don't return anything useful - in which case it should degrade gracefully to the subset of functionality that can be accessed through backend-independent GTK calls. Accordingly, I've centralised the use of GDK_DISPLAY_XDISPLAY into a support function get_x_display() in gtkmisc.c, which starts by checking that there actually is one first. All previous direct uses of GDK_*_XDISPLAY now go via that function, and check the result for NULL afterwards. (To save faffing about calling that function too many times, I'm also caching the display pointer in more places, and passing it as an extra argument to various subfunctions, mostly in gtkfont.c.) Similarly, the get_windowid() function that retrieves the window id to put in the environment of pterm's child process has to be prepared for there not to be a window id. This isn't a complete fix for all Wayland-related problems. The other one I'm currently aware of is that the default font is "server:fixed", which is a bad default now that it won't be available on all backends. And I expect that further problems will show up with more testing. But it's a start.

Similarly, the get_windowid() function that retrieves the window id to put in the environment of pterm's child process has to be prepared for there not to be a window id. This isn't a complete fix for all Wayland-related problems. The other one I'm currently aware of is that the default font is "server:fixed", which is a bad default now that it won't be available on all backends. And I expect that further problems will show up with more testing. But it's a start.

Basic support for running under GDK Wayland back end. GTK 3 PuTTY/pterm has always assumed that if it was compiled with _support_ for talking to the raw X11 layer underneath GTK and GDK, then it was entitled to expect that raw X11 layer to exist at all times, i.e. that GDK_DISPLAY_XDISPLAY would return a meaningful X display that it could do useful things with. So if you ran it over the GDK Wayland backend, it would immediately segfault. Modern GTK applications need to cope with multiple GDK backends at run time. It's fine for GTK PuTTY to _contain_ the code to find and use underlying X11 primitives like the display and the X window id, but it should be prepared to find that it's running on Wayland (or something else again!) so those functions don't return anything useful - in which case it should degrade gracefully to the subset of functionality that can be accessed through backend-independent GTK calls. Accordingly, I've centralised the use of GDK_DISPLAY_XDISPLAY into a support function get_x_display() in gtkmisc.c, which starts by checking that there actually is one first. All previous direct uses of GDK_*_XDISPLAY now go via that function, and check the result for NULL afterwards. (To save faffing about calling that function too many times, I'm also caching the display pointer in more places, and passing it as an extra argument to various subfunctions, mostly in gtkfont.c.)

Post-release destabilisation!

Initial support for clipboard on OS X. Rather than trying to get my existing hugely complicated X-style clipboard code to somehow work with the Quartz GTK back end, I've written an entirely new and much simpler alternative clipboard handler usnig the higher-leve GtkClipboard interface. It assumes all clipboard text can be converted to and from UTF-8 sensibly (which isn't a good assumption on all front ends, but on OS X I think it's reasonable), and it talks to GDK_SELECTION_CLIPBOARD rather than PRIMARY, which is the only clipboard OS X has. I had to do a fiddly thing to cope with the fact that each call to gtk_clipboard_set_with_data caused a call to the clipboard clear function left over from the previous set of data, so I had to avoid mistaking that for a clipboard-clear for the _new_ data and immediately deselecting it. I did that by allocating a distinct placeholder object in memory for each instance of the copy operation, so that I can tell whether a clipboard-clear is for the current copy or a previous one. This is only very basic support which demonstrates successful copying and pasting is at least possible. For a sensible OS X implementation we'll need a more believable means of generating a paste UI action (it's quite easy to find a Mac on which neither Shift-Ins nor the third mouse button even exists!). Also, after the trouble I had with the clipboard-clear event, it's a bit annoying to find that it _doesn't_ seem to get called when another application becomes the clipboard owner. That may just be something we have to put up with, if I can't find any reason why it's failing.

Stop using the GTK "configure-event" signal. I've been using that signal since the very first commit of this source file, as a combined way to be notified when the size of the drawing area changes (typically due to user window resizing actions) and also when the drawing area is first created and available to be drawn on. Unfortunately, testing on Ubuntu 18.04, I ran into an oddity, in which the call to gtk_widget_show(inst->window) in new_session_window() has the side effect of delivering a spurious configure_event on the drawing area with size 1x46 pixels. This causes the terminal to resize itself to 1 column wide, and the mistake isn't rectified until a followup configure-event arrives after new_session_window returns to the GTK main loop. But that means terminal output can occur between those two configure events (the connection-sharing "Reusing a shared connection to host.name" is a good example), and when it does, it gets embarrassingly wrapped at one character per line down the left column. I briefly tried to bodge around this by trying to heuristically guess which configure events were real and which were spurious, but I have no faith in that strategy continuing to work. I think a better approach is to abandon configure-event completely, and move to a system in which the two purposes I was using it for are handled by two _different_ GTK signals, namely "size-allocate" (for knowing when we get resized) and "realize" (for knowing when the drawing area physically exists for us to start setting up Cairo or GDK machinery). The result seems to have fixed the silly one-column wrapping bug, and retained the ability to handle window resizes, on every GTK version I have conveniently available to test on, including GTK 3 both before and after these spurious configures started to happen.

GTK 3: be aware of the window's scale factor. In GTK 3.10 and above, high-DPI support is arranged by each window having a property called a 'scale factor', which translates logical pixels as seen by most of the GTK API (widget and window sizes and positions, coordinates in the "draw" event, etc) into the physical pixels on the screen. This is handled more or less transparently, except that one side effect is that your Cairo-based drawing code had better be able to cope with that scaling without getting confused. PuTTY's isn't, because we do all our serious drawing on a separate Cairo surface we made ourselves, and then blit subrectangles of that to the window during updates. This has two bad consequences. Firstly, our surface has a size derived from what GTK told us the drawing area size is, i.e. corresponding to GTK's _logical_ pixels, so when the scale factor is (say) 2, our drawing takes place at half size and then gets scaled up by the final blit in the draw event, making it look blurry and unpleasant. Secondly, those final blits seem to end up offset by half a pixel, so that a second blit over the same subrectangle doesn't _quite_ completely wipe out the previously blitted data - so there's a ghostly rectangle left behind everywhere the cursor has been. It's not that GTK doesn't _let_ you find out the scale factor; it's just that it's in an out-of-the-way piece of API that you have to call specially. So now we do: our backing surface is now created at a pixel resolution matching the screen's real pixels, and we translate GTK's scale factor into an ordinary cairo_scale() before we commence drawing. So we still end up drawing the same text at the same size - and this strategy also means that non-text elements like cursor outlines and underlining will be scaled up with the screen DPI rather than stubbornly staying one physical pixel thick - but now it's nice and sharp at full screen resolution, and the subrectangle blits in the draw event are back to affecting the exact set of pixels we expect them to. One silly consequence is that, immediately after removing the last one, I've installed a handler for the GTK "configure-event" signal! That's because the GTK 3 docs claim that that's how you get notified that your scale factor has changed at run time (e.g. if you reconfigure the scale factor of a whole monitor in the GNOME settings dialog). Actually in practice I seem to find out via the "draw" event before "configure" bothers to tell me, but now I've got a usefully idempotent function for 'check whether the scale factor has changed and sort it out if so', I don't see any harm in calling it from anywhere it _might_ be useful.

Post-release destabilisation! Completely remove the struct type 'Config' in putty.h, which stores all PuTTY's settings and includes an arbitrary length limit on every single one of those settings which is stored in string form. In place of it is 'Conf', an opaque data type everywhere outside the new file conf.c, which stores a list of (key, value) pairs in which every key contains an integer identifying a configuration setting, and for some of those integers the key also contains extra parts (so that, for instance, CONF_environmt is a string-to-string mapping). Everywhere that a Config was previously used, a Conf is now; everywhere there was a Config structure copy, conf_copy() is called; every lookup, adjustment, load and save operation on a Config has been rewritten; and there's a mechanism for serialising a Conf into a binary blob and back for use with Duplicate Session. User-visible effects of this change _should_ be minimal, though I don't doubt I've introduced one or two bugs here and there which will eventually be found. The _intended_ visible effects of this change are that all arbitrary limits on configuration strings and lists (e.g. limit on number of port forwardings) should now disappear; that list boxes in the configuration will now be displayed in a sorted order rather than the arbitrary order in which they were added to the list (since the underlying data structure is now a sorted tree234 rather than an ad-hoc comma-separated string); and one more specific change, which is that local and dynamic port forwardings on the same port number are now mutually exclusive in the configuration (putting 'D' in the key rather than the value was a mistake in the first place). One other reorganisation as a result of this is that I've moved all the dialog.c standard handlers (dlg_stdeditbox_handler and friends) out into config.c, because I can't really justify calling them generic any more. When they took a pointer to an arbitrary structure type and the offset of a field within that structure, they were independent of whether that structure was a Config or something completely different, but now they really do expect to talk to a Conf, which can _only_ be used for PuTTY configuration, so I've renamed them all things like conf_editbox_handler and moved them out of the nominally independent dialog-box management module into the PuTTY-specific config.c.
