2016-09-22hurdmalloc: Run fork handler as late as possible [BZ #19431]Samuel Thibault
This is the hurd-specific follow-up for 29d794863cd6e03115d3670707cc873a9965ba92 : hurdmalloc also needs the same fix * hurd/hurdmalloc.c (malloc_fork_prepare): Rename to _hurd_malloc_fork_prepare. (malloc_fork_parent): Rename to _hurd_malloc_fork_parent. (malloc_fork_child): Rename to _hurd_malloc_fork_child. (_hurd_fork_prepare_hook): Drop malloc_fork_prepare. (_hurd_fork_parent_hook): Drop malloc_fork_parent. (_hurd_fork_child_hook): Drop malloc_fork_child. * hurd/hurdmalloc.h (_hurd_malloc_fork_prepare, _hurd_malloc_fork_parent, _hurd_malloc_fork_child): Add declarations. * sysdeps/mach/hurd/fork.c (__fork): Call __malloc_fork_lock_parent after locking locks (notably hurd_dtable_lock). Call _hurd_malloc_fork_prepare after that. Call _hurd_malloc_fork_parent before __malloc_fork_unlock_parent and _hurd_malloc_fork_child before __malloc_fork_unlock_child.
2015-10-20Convert 113 more function definitions to prototype style (files with ↵Joseph Myers
assertions). This mostly automatically-generated patch converts 113 function definitions in glibc from old-style K&R to prototype-style. Following my other recent such patches, this one deals with the case of function definitions in files that either contain assertions or where grep suggested they might contain assertions - and thus where it isn't possible to use a simple object code comparison as a sanity check on the correctness of the patch, because line numbers are changed. A few such automatically-generated changes needed to be supplemented by manual changes for the result to compile. openat64 had a prototype declaration with "..." but an old-style definition in sysdeps/unix/sysv/linux/dl-openat64.c, and "..." needed adding to the generated prototype in the definition (I've filed <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68024> for diagnosing such cases in GCC; the old state was undefined behavior not requiring a diagnostic, but one seems a good idea). In addition, as Florian has noted regparm attribute mismatches between declaration and definition are only diagnosed for prototype definitions, and five functions needed internal_function added to their definitions (in the case of __pthread_mutex_cond_lock, via the macro definition of __pthread_mutex_lock) to compile on i386. After this patch is in, remaining old-style definitions are probably most readily fixed manually before we can turn on -Wold-style-definition for all builds.
