2018-11-13replace: Add check for variable program_invocation_short_nameMartin Schwenke1-0/+1
It appears that wafsamba's configure() defines _GNU_SOURCE unconditionally, so checking _GNU_SOURCE isn't enough to know if this variable is available. For example, it isn't available on AIX with the xlc compiler: [ 6/10] Compiling lib/replace/replace.c ... "../../lib/replace/replace.c", line 991.16: 1506-045 (S) Undeclared identifier program_invocation_short_name. Instead, add a configure check for program_invocation_short_name and use it.

There is closefrom in some BSDs, but Linux ships this only as part of libbsd. Add a new implementation of it in libreplace. The one in libbsd of jessie and upstream differ and it has for example optimizations for FreeBSD, but it gets some of the array calculations slightly wrong from my point of view. If you want those, use libbsd. This replacement is optimized on Linux only looking at /proc/self/fd/, everything else would do the OPEN_MAX brute force fallback.

CHECK_CODE already wraps the code with main(). Adding another layer results in a nested function, eg int main(void) { int main(void) { __sync_fetch_and_add(); } } Since the inner function isn't called it is optimized out at cc -O2, thus the linker doesn't fail if __sync_fetch_and_add() isn't available.

2015-11-06build:wafsamba: Remove samba_utils.runonceThomas Nagy1-2/+2
The decorator order matters in the following: """ @runonce @conf function() """ First, the @conf decorator binds the function to the configuration context and then returns the same function. The @runonce decorator then takes the output function and replaces it by another that performs caching. This new function remains in the current script and is never bound to the configuration context, so caching never occurs. The declaration would have been correct if written like this: """ @conf @runonce function() """ Yet the decorator @run_once does not keep the function name (__name__), so the annotation with @conf would fail. The straightforward approach is to remove all the incorrect @runonce occurrences. Besides that, the function Utils.run_once is already present in the Waf library, and is sufficient for the current needs of the Samba code (it caches only the first argument). Therefore samba_utils.runonce can be safely replaced by Utils.run_once, which is also present in Waf 1.8. Note: at runtime, only SETUP_BUILD_GROUPS seems to actually use caching.
