This commit changes wxExecute() to handle SIGCHLD to be notified about the
child process termination instead of detecting when the file descriptor
corresponding to the other end of a pipe opened in the parent process was
closed in the child as this was not reliable and could (and did) result in not
detecting the termination of the child processes that closed all their file
descriptors before exiting.
This commit also removes a lot of platform-specific code duplicating the
generic event loop sources support and reuses it for wxExecute() purposes too.
Final big change is that wxEndProcessData was merged into wxExecuteData and we
don't have two similar but quite different classes any more but just one,
which is used both to pass the information from wxExecute() to wxAppTraits
methods and to store this information until the child termination.
This method always returns some valid traits, even if we don't have wxTheApp
(which is possible in the console applications) or if its GetTraits() was
overridden to return NULL (which shouldn't be, but still guard against this).
Treat G_IO_HUP as read, not error, event because EOF is not exceptional.
When EOF is reached on a file descriptor, call the handler OnReadWaiting()
because this is not really different from getting to the EOF while reading
data in the same function. Only call OnExceptionWaiting() for the real errors.
Make Unix wxAppConsole signal handling more flexible.
Instead of hardcoding the call to WakeUpIdle() in the signal handler itself,
just wake up the event loop when we catch a signal. This will still result in
WakeUpIdle() being called, before the next event loop iteration, but it will
also allow us to do other things on wakeup from signal as it will be done in
the upcoming wxExecute() changes to support wxEXEC_NOEVENTS in console
applications.
Change wxWakeUpPipe to be a wxEventLoopSourceHandler.
No real changes but use wxEventLoopSource::AddSourceForFD() instead of
wxFDIODispatcher::RegisterFD() for this pipe because this is the preferred way
and because it will allow reusing this class for wxExecute() purposes later.
This is necessary to ensure that wxUSE_EVENTLOOP_SOURCE which wraps the entire
contents of this header is defined if it's included directly and not after
already including wx/evtloop.h.
This just reads everything remaining in the stream in a blocking way and will
be used to get the data remaining in the stream buffers after the child
process had been already closed (and hence can't write any more to it and
there is no risk of deadlock).
Use CFSocket instead of CFFileDescriptor in wxCFEventLoopSource.
Use OS X socket APIs for monitoring file descriptors. They are more flexible
than CFFileDescriptor functions and can be used with any descriptors, not
necessarily the socket ones.
Any event sources should be registered with all the event loops, including the
ones that will be started in the future, and not only the current (and
potentially not even existing yet) one. So make AddSourceForFD() method static.
To still allow it to do different things in console and GUI applications, as
it must, virtualize it via the new wxEventLoopSourcesManager class which has
different implementations in the two cases, returned via wxAppTraits as usual.
Notice that this required moving the implementation of this method from
src/osx/core/evtloop_cf.cpp to src/osx/core/utilsexc_cf.cpp as the former file
is base-only and didn't have access to wxGUIAppTraits.
Split wxWakeUpPipe class in MT-unsafe and MT-safe parts.
This class can also be useful when it's used in the main thread only, so
leave the lock-less part of the code in wxWakeUpPipe and derive a separate
wxWakeUpPipeMT from it for the use in wxConsoleEventLoop where it can be used
by multiple threads.
No changes, move wxStreamTempInputBuffer to a header file.
Get rid of the surprising src/common/execcmn.cpp which had a .cpp extension
but was supposed to be used as an included file only and move its contents to
a new private header to make using wxStreamTempInputBuffer class simpler.
Extract wxPipeInputStream and wxPipeOutputStream in a header.
No real changes, just put these classes in a private header. They're still not
part of the public API but at least it will be easier to reuse them inside the
library itself in the upcoming commits.
This method allows to request exiting from the given event loop even if it's
not the currently active one, unlike Exit() which would assert in this case.
With it, it becomes possible to ask the loop to terminate as soon as possible
even if a nested loop is currently running.
Don't create an event loop manually, let the port-specific code do it and run
it as usual in the GUI unit tests.
This has several advantages:
- No need to manage the event loop manually in the test.
- No need for Mac-specific code in the test itself.
- Code being tested runs in the same context as in a normal GUI program,
which is especially important for event-loop related tests under wxOSX as
the main event loop is special there.
This is a simple wrapper for wxTimer::Start(timeout, wxTIMER_ONE_SHOT) but is
often more readable and is definitely better than Start(timeout, true) which
many people still use in spite of wxTIMER_ONE_SHOT existence.
Better fix for duplicate wxContextMenuEvent generation under MSW.
Fix the bug with multiple wxContextMenuEvent being generated for a single
WM_CONTEXTMENU without breaking context menus for wxTextCtrl (and all the
other native controls). Do this by ensuring that WM_CONTEXTMENU is still
passed to DefWindowProc() if we don't process it instead of just being eaten
completely in any case.
Also add a unit test checking for this bug to ensure it stays fixed.
Avoid forcing wxYield() after wxUIActionSimulator::MouseMove() in wxGTK.
Yield (for input events only) inside this function itself instead of forcing
all the code using this function to call wxYield() after it as otherwise the
mouse position change is not taken into account by the subsequent simulated
events.
Optimize wxImage::Scale() by pre-calculating the values used.
Precompute the values used by various resampling algorithms once instead of
doing it for each pixel. This dramatically speeds them up: more than 3 times
faster in wxImage benchmark with the small images and up to 5 times faster
with larger images.
Check that resizing the test horse image produces the same results in the
future as it does now, by saving the current results in files and verifying
that images resized directly and loaded from these files are the same.

Fix missing documentation for several GDI functions.

Forward events to active child in wxMDIParentFrameBase, not only wxMSW.
Menu, toolbar and update UI events should be forwarded to the active child
under all platforms in MDI applications and not only MSW, so move TryBefore()

This should make things more consistent in general and notably fixes the lack
of toolbar events in wxDocChildFrame since the changes of r73928.

We always appended the default extension (for the currently selected pattern)

Also propagate wxEVT_UPDATE_UI to the child MDI frame.

Use child MDI frame menu items in preference to the parent frame ones.
Look for the item with the given ID in the child frame menu bar first, before
looking in the parent frame menu bar. This ensures that if an item is disabled
by the parent frame but then reenabled by the child one, it still generates
commands as expected instead of being completely ignored.
