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.
See #10258.

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.
See #10258.

We need a space between the command and stderr redirection to avoid the "2"
from being taken as part of the last option on the command line.

Redirect stderr to /dev/null in wxGetCommandOutput() to avoid errors from the
shell if the command we're trying to run doesn't exist.

This fixes compilation of non-wxOSX ports (e.g. wxGTK) under OS X.
Also make the difference between the two symbols more clear in the
documentation.
Closes#14503.

This compiler doesn't exist any more and was probably unsupported even in 2.8,
let alone 2.9, so remove all the __MWERKS__ tests to simplify things.

The code closing all file descriptors inherited from the parent in the child
process created by wxExecute() was removed in r57324 by mistake (probably
due the fact that its meaning was poorly explained) but we still do need to do
this, of course, to avoid descriptor "leaks" (e.g. the parent couldn't really
close any of them).
Restore the code for closing all unneeded file descriptors in the child in
slightly modified form and add a comment pointing to an URL explaining how to
do it better in the future.
Closes#12636.

Since the child pipe was made non-blocking in r65993, it became possible to
write to child process without deadlocking when the pipe became full. However
this still resulted in an error from wxFileOutputStream as it didn't handle
EAGAIN returned from write() any differently than any other error, even though
it is an expected situation in this particular case.
Change Unix wxExecute() to use wxPipeOutputStream which ignores EAGAIN unlike
wxFileOutputStream to fix this.
See #12636.

Renamed the symbol indicating whether pipe-based streams are available from
HAS_PIPE_INPUT_STREAM to HAS_PIPE_STREAMS as it's not really input-specific.
See #12636.

No real changes, just add some wxUnusedVar() to avoid warnings about
parameters unused in some non-default build configurations.
git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@66090 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
We need to make at least one end of the pipe used to communicate with
wxExecute() child process non-blocking to avoid deadlocks, so unblock the
write end of the pipe. It seems to be unnecessary to unblock the reading ends
of std{out,err} pipes as we can already check for the presence of input there.
This is also consistent with wxMSW behaviour.
Closes#12636.

Add an optional wxExecuteEnv parameter to wxExecute() which allows to specify
the initial working directory and custom environment for the child process.
Closes#12163.

The caller expects the function to return -1 if the child process exited with
-1 error code and not 255 that was returned before. The function is also
documented as returning -1 if the execution fails which wasn't true neither.
Fix this by explicitly handling the exit code as signed.
Closes#11824.

This commit is huge but there are no non-white-space changes in it.
Some files containing third-party sources (src/msw/wince/time.cpp,
src/x11/pango*.cpp) were left unchanged.

idea why the current code used for Intel Macs doesn't work but it's not
working for me at all. This should probably be backported to 2.8.
