Currently, ipc/chromium detects sparc64 by checking whether
__sparc64__ is defined. However, this definition is used on BSD
targets only. Linux targets define both __sparc__ and __arch64__
on sparc64. Since this also works on BSD, rather use __sparc__
and __arch64__ instead of __sparc64__ to detect sparc64 targets.
This is gnarly IPDL code, but the generated code is probably easier to
review. Before when sending a sync message, we had:
bool sendok__ = (GetIPCChannel())->Send(msg__, (&(reply__)));
if ((!(sendok__))) {
return false;
}
Now, we have:
bool sendok__;
{
GeckoProfilerTracingRAII syncIPCTracer(
"IPC",
"PJavaScript::Msg_PreventExtensions");
sendok__ = (GetIPCChannel())->Send(msg__, (&(reply__)));
}
if ((!(sendok__))) {
return false;
}
Every new PBrowser, whether it's created by the parent or the child, needs
to get a TabGroup assigned to it. That way IPC messages for the PBrowser will
be dispatched to that TabGroup.
For new PBrowsers created by the child, we just create a new TabGroup or reuse
the opener's TabGroup.
For PBrowsers created by the parent, the child needs to intercept the
PBrowserConstructor message and assign a TabGroup immediately. PBrowsers created
by the parent never have an opener so we can always create a new TabGroup.
In both cases, the nsGlobalWindow::TabGroupOuter logic needs to be updated to
read the TabGroup out of the IPC code. Otherwise the DOM and IPC code will get
out of sync about TabGroups.

This patch removes all user-specified state machine support from the
IPDL parser, then deletes all of the code related to it from the AST,
type checking, and code generation. The default state machine code
relating to tracking whether the protocol is dead or not will still be

generated for any protocol that does not use the custom state machine
syntax.

MessageId has the production "'~' ID", but if you use it, it produces

The IPDL parser handles include statements by using a stack of
parsers. If an inner parser encounters a parsing error, it will print
out an error message, which is maybe okay, but then it makes two
mistakes:
1. It does not pop the current parser off of the parser stack. This
means that the file that included the syntactically invalid file will
be parsed as though it were the invalid file. In bkelly's case, an
.ipdl file included an invalid .ipdlh file, so he got a bizarre error
message about how you can't define a protocol in a header, because the
parser was treating the protocol in the .ipdl file as though it were
in the .ipdlh file. I fixed this by using a "finally" clause to pop
the parser stack, ensuring that it is correct even in case of error.
2. A parse error in the include should cause the entire parse to fail,
but instead it will keep going. inc.tu will get set to None, which
eventually causes an error later in type checking, when it attempts to
examine inc.tu. I fixed this by only catching the parse error where we
invoke the outermost parser. This has the drawback that later errors
in other files will not be reported. An alternate fix would set a
global flag to indicate that a parse error had occured, and somehow
report that to the caller.
I think this bug was introduced in 2009 by commit
cb8189926a69872c73508fba50830f0d07af341f.

Giving '0' (literal zero) to RefPtr is now ambiguous, as both
RefPtr(decltype(nullptr)) and RefPtr(T*) could be used.
In any case, our coding standards mandate the use of 'nullptr' for pointers.

This patch moves FatalError to IProtocol. I had to make a few changes.
- I added a ProtocolName() method to find the name of the protocol.
- I gave the two-argument version of FatalError its own name. Otherwise
C++ doesn't like there to be two virtual methods with the same name
in cases where one is overridden and the other isn't (as happens
in IToplevelProtocol).
Moves OnProcessingError, OnChannelError, OnChannelConnected so that they're
only generated for toplevel protocols. For some reason APZCTreeManagerChild
implemented OnProcessingError. I'm not sure what the intention was there so
I removed it.
This moves some of the generated methods in subprotocols that simply defer
to the parent protocol to IProtocol. These methods are still overridden in
the toplevel protocol.
This patch stores mManager in IProtocol rather than in each individual
PFoo. It also adds a generic accessor for that field. Note that each
individual protocol still defines a Manager() function that returns
PFooParent or whatever. I tried to get rid of that but it was a lot
of work.
With this change, MessageChannel stores mListener as an IToplevelProtocol
rather than a MessageListener (which isn't really a useful concept on
its own). The MessageListener methods are split out to IProtocol and
IToplevelProtocol. MessageListener gets deleted. Some of the inline
functions in MessageChannel had to be moved to MessageChannel.cpp since
IToplevelProtocol isn't defined in MessageChannel.h.
Currently toplevel protocols inherit from both IProtocolManager<IProtocol>
and IToplevelProtocol. This change makes IToplevelProtocol inherit from
IProtocol, so now toplevel protocols only inherit from
IToplevelProtocol.
Currently all our protocols inherit from IProtocolManager<IProtocol>. I have
no idea why. This patch switches everything over to IProtocol, without any
templates. I had to move ReadActor to the .cpp file to avoid redefinition
errors.
This way they'll continue to be at the beginning of the symbol search
path after mozsandbox returns to being a shared library instead of
statically linked into plugin-container.

clang has recently made |x $RELATIONAL_OP 0|, where |x| is a variable of
pointer type, to be an error. On Windows,
GeckoChildProcessHost::mChildProcessHandle is a HANDLE, which is really
just a pointer. So the comparison |> 0| in ~GeckoChildProcessHost is
invalid. Fortunately, we can use an equality comparison here and it
amounts to the same thing.
For every protocol's RemoveManagee method, and every sub-protocol that
protocol manages, we generate:
MOZ_DIAGNOSTIC_ASSERT(mManagedPSubProtcolChild.Contains(actor), "...");
which dumps strings into the binary like:
(mManagedPAsmJSCacheEntryChild).Contains(actor) (actor not managed by this!)
MOZ_RELEASE_ASSERT((mManagedPAsmJSCacheEntryChild).Contains(actor)) (actor not managed by this!)
The linker is capable of merging multiple strings together, but
including the sub-protocol in every assert expression effectively
defeats this linker optimization, resulting in ~40KB of unnecessary
strings.
We can improve this situation by taking a reference to the managee
container, and using that reference in the assertion expression. All
the assertion expressions are identical, and the linker can perform the
expected string merging, for a savings of ~40KB.
