- Pass null scope objects into nsIScriptContext::Compile{EventHandler,Script}
when precompiling for brutal sharing. The JS engine does not need a non-null
object parameter for static scope. That parameter can be non-null only if it
helps the compiler "pre-bind" functions to the same scope object that they'll
be parented by when executing, but with brutal sharing, functions are
precompiled once and executed against many different scope objects.
- A problem in XUL FastLoad was that it would serialize master .xul document
out-of-line scripts (those included via script src= from non-overlay, "master"
.xul docs) far from the place in the FastLoad file where XUL prototype script
info was serialized for the <script src=> tag itself. I fixed that so that,
unless the out-of-line script was previously serialized (by a different src=
reference from another .xul file), the OOL script data immediately follows the
proto-script info in the FastLoad file.
This required adding a SerializeOutOfLine method to nsXULPrototypeScript, which
restores symmetry by matching the existing DeserializeOutOfLine(Script) (note:
I dropped the redundant "Script" from the end of the latter method's name. We
need SerializeOutOfLine to handle overlay OOL scripts. They are serialized by
nsXULDocument::OnStreamComplete, because that code knows the difference between
an overlay and a master doc. This removes all trace of FastLoad writing from
nsXULPrototypeScript::Compile -- FastLoad stuff didn't belong there, not only
because we now want to write master OOL scripts later, when walking the master
XUL prototype doc's element tree, but also for modularity reasons. The caller
knows about FastLoad, nsXULPrototypeScript::Compile does just what its name
implies.
There are 132 seeks with the patch, only 49 of which dump the underlying file
stream's buffer, vs. 133 seeks without the patch, 87 of which dump the buffer.
- Nit-picked some comments to fit in 80 columns, and made other cosmetic fixes.
- Implicated the nsXULDocument::mIsWritingFastLoad flag from the useXULCache
"is the XUL cache enabled?" flag, so other places that test mIsWritingFastLoad
don't have to query whether the cache is enabled.
- Added METERING synchronous meter-dumping to /tmp/bufstats, only ifdef
DEBUG_brendan, in netwerk/base/src/nsBufferedStreams.cpp.
- Added the deferred seek optimization from the first patch in bug 195010 to
nsFastLoadFile.cpp.
- Fixed nsFastLoadFileReader so it overrides readSegments as well as read.
This catches up with the interface extension made to nsIInputStream to add
readSegments. The nsFastLoadFileReader extends nsBinaryInputStream, which is
a concrete class, and overrides Read in order to snoop on *all* bytes read.
It does this in order to demultiplex documents interleaved when the FastLoad
file was written.
But since the readSegments move into nsIInputStream.idl, certain primitives
in nsBinaryStream.cpp, e.g., nsBinaryInputStream::ReadCString, have used
ReadSegments, not Read, to consume parts of the underlying stream (to read
the C string's chars, in that example), and the FastLoad file implementation
has not accounted for those bytes.
- Added a new method to nsIFastLoadFileControl and its impls: hasMuxedDocument.
This is needed when serializing master XUL doc OOL scripts, because we must
not serialize twice, and any OOL script that other XUL docs can include via
script src= could already be in the FastLoad mux.

Moved nsFileSpec and related classes into this obsolete library.
Moved nsRegistry and related libreg functionality into the obsolete library.
Updated many callers using the obsolete nsFile spec to use nsIFile and Necko to do file IO.
Combined the following DLLs (source -> dest)
uriloader -> docshell
shistory -> docshell
jsurl -> jsdom
gkview -> gklayout
Moved nsAdapterEnumerator out of xpcom/ds and into mailnews, since they're the only consumer
Modifed the xpt_link tool so that you can specify a �only include� cid list that can mask CID�s that you are not interested in.
Added build options:
Prevent the building of xpinstall (--disable-xpinstall)
Prevent the building js component loader (--disable-jsloader)
A build option to only build a single profile (--enable-single-profile)
A build flag to only built the required xpfe components (--disable-xpfe-components).
Removal or hiding of unused functions and classes including nsEscape*, nsDequeIterator, nsRecyclingAllocatorImpl, nsDiscriminatedUnion, nsOpaqueKey, nsCRT::strlen, NS_NewCommandLineService
Bug 194240, r/sr = darin, alec.
Add stub declaration for _mbstr which isn't defined in the current mingw headers but is present in the libs.
Fix GRE definition of XPCOM_DLL for mingw.
Bug #134113 r=dougt
- hide Fill() (or remove it where not necessary)
- add ReadSegments() so that we can do reads without copying
- remove the extra offset parameter to Read()
r=dougt, sr=darin
is never 0, and make the memset-to-zero required for these assertions be
#ifdef NS_DEBUG.
- Extend FastLoad file format to encode a singleton flag in the high bit of
nsFastLoadSharpObjectInfo.mWeakRefCnt. The updater code needs to test this
bit in order to deserialize a singleton that was not read by the updater's
reader during this FastLoad episode. Otherwise the updater is likely to
reserialize the singleton, leading to multiple entries in the object map
for the same object, and UMRs when loading from the writer's object map
enumeration (objvec) in nsFastLoadFileWriter::WriteFooter.
- Remove bogus assertion that worked only when an XPCOM data structure being
serialized was still alive at the time the writer closed. In general, there
is no relationship between the strong ref-counts in a FastLoad file and the
XPCOM refcnts in memory at close time.
