qpid-dispatch fails to build with Python 3.13.0a1.

This report is automated and not very verbose, but we'll try to get back here with details.


/builddir/build/BUILD/qpid-dispatch-1.19.0/src/dispatch.c:82:5: error: implicit declaration of function ‘gettimeofday’ [-Wimplicit-function-declaration]

/builddir/build/BUILD/qpid-dispatch-1.19.0/src/dispatch.c:412:26: error: implicit declaration of function ‘getpid’; did you mean ‘getpt’? [-Wimplicit-function-declaration]

From https://docs.python.org/3.13/whatsnew/3.13.html:

- Python.h no longer includes the <unistd.h> standard header file. If needed, it should now be included explicitly. For example, it provides the functions: read(), write(), close(), isatty(), lseek(), getpid(), getcwd(), sysconf() and getpagesize(). As a consequence, _POSIX_SEMAPHORES and _POSIX_THREADS macros are no longer defined by Python.h. The HAVE_UNISTD_H and HAVE_PTHREAD_H macros defined by Python.h can be used to decide if <unistd.h> and <pthread.h> header files can be included. (Contributed by Victor Stinner in gh-108765.)

- Python.h no longer includes these standard header files: <time.h>, <sys/select.h> and <sys/time.h>. If needed, they should now be included explicitly. For example, <time.h> provides the clock() and gmtime() functions, <sys/select.h> provides the select() function, and <sys/time.h> provides the futimes(), gettimeofday() and setitimer() functions.

For all our attempts to build qpid-dispatch with Python 3.13, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.13/package/qpid-dispatch/

Testing and mass rebuild of packages is happening in copr.
You can follow these instructions to test locally in mock if your package builds with Python 3.13:
https://copr.fedorainfracloud.org/coprs/g/python/python3.13/

Let us know here if you have any questions.

Python 3.13 is planned to be included in Fedora 41.
To make that update smoother, we're building Fedora packages with all pre-releases of Python 3.13.
A build failure prevents us from testing all dependent packages (transitive [Build]Requires),
so if this package is required a lot, it's important for us to get it fixed soon.

We'd appreciate help from the people who know this package best,
but if you don't want to work on this now, let us know so we can try to work around it on our side.
