gpgme/src/posix-io.c, branch gpgme-1.10.0

core: use getdents64 syscall on linux instead of getdents.

2017-10-12T07:00:09Z

* src/posix-io.c (get_max_fds): use getdents64 instead of getdents. -- getdents64 was introduced in linux 2.4, so it should be widely available. some Linux architectures which post-date 2.4 (e.g. arm64) appear to not have getdents at all, so it's probably better to use the more modern interface.

core: Allow disabling the use of SYS_getdents for Linux.

* configure.ac (USE_LINUX_GETDENTS): New ac_define. Add option --disable-linux-getdents. * src/posix-io.c: Make use of USE_LINUX_GETDENTS. Signed-off-by: Werner Koch

core: Restore get_max_fds optimization on Linux

2017-10-04T15:26:39Z

* src/posix-io.c (get_max_fds): Restore Linux optimization, this time using open/getdents/close rather than opendir/readdir/closedir. -- opendir/readdir/closedir may allocate/free memory, and aren't required to do so in an async-signal-safe way. On the other hand, opening /proc/self/fd directly and iterating over it using getdents is safe. (getdents is not strictly speaking documented to be async-signal-safe because it's not in POSIX. However, the Linux implementation is essentially just a souped-up read. Python >= 3.2.3 makes the same assumption.) Signed-off-by: Colin Watson

FreeBSD's closefrom(2) does not return errors

core: Optimize fork/exec for *BSD and Solaris.

2017-02-03T12:56:23Z

* configure.ac (closefrom): Add to ac_check_funcs. * src/posix-io.c (_gpgme_io_spawn): Use closefrom. Signed-off-by: Werner Koch

core: Fix possible deadlock due to get_max_fds.

2017-02-03T12:13:22Z

* src/posix-io.c (get_max_fds): Do not use the Linux optimization. -- Signed-off-by: Werner Koch

doc: Replace http: by https: in core source files.

core: Use better error code when using select with a too high fd.

2016-11-10T18:49:58Z

* src/posix-io.c (_gpgme_io_select): Return EMFILE instead of EBADF. -- Also EBADF seem more correct, EMFILE (Too man open files) gives a clearer message to the user that there are somehow too many files open. The problem can be exhibited by running lots of threads, We should eventually move to poll but that would be a large change and so we better fix it with the planned migration of the I/O subsystem to libgpgrt (currently known as libgpg-error).

core: Use const char * where appropriate.
