2020-09-17nscd: bump GC cycle during cache pruning (bug 26130)Andreas Schwab
While nscd prunes a cache it becomes inconsistent temporarily, which is visible to clients if that cache is shared. Bump the GC cycle counter so that the clients notice the modification window. Uniformly use atomic_fetch_add to modify the GC cycle counter.

Also, change sources.redhat.com to sourceware.org. This patch was automatically generated by running the following shell script, which uses GNU sed, and which avoids modifying files imported from upstream: sed -ri ' s,(http|ftp)(://(.*\.)?(gnu|fsf|sourceware)\.org($|[^.]|\.[^a-z])),https\2,g s,(http|ftp)(://(.*\.)?)sources\.redhat\.com($|[^.]|\.[^a-z]),https\2sourceware.org\4,g ' \ $(find $(git ls-files) -prune -type f \ ! -name '*.po' \ ! -name 'ChangeLog*' \ ! -path COPYING ! -path COPYING.LIB \ ! -path manual/fdl-1.3.texi ! -path manual/lgpl-2.1.texi \ ! -path manual/texinfo.tex ! -path scripts/config.guess \ ! -path scripts/config.sub ! -path scripts/install-sh \ ! -path scripts/mkinstalldirs ! -path scripts/move-if-change \ ! -path INSTALL ! -path locale/programs/charmap-kw.h \ ! -path po/libc.pot ! -path sysdeps/gnu/errlist.c \ !

2009-07-17Revert "Fix lock handling in memory hander of nscd."Ulrich Drepper
This reverts commit 137028b4d7e50f71906c1656c27079eac5a1d085. Conflicts: ChangeLog
2009-07-16Fix lock handling in memory hander of nscd.Petr Baudis
The commit 20e498bd removes the pthread_mutex_rdlock() calls, but not the corresponding pthread_mutex_unlock() calls. Also, the database lock is never unlocked in one branch of the mempool_alloc() if. I think unreproducible random assert(dh->usable) crashes in prune_cache() were caused by this. But an easy way to make nscd threads hang with the broken locking was.
