In iconv/gconv_conf.c, __gconv_get_path unnecessarily obtains a lock when populating the array pointed to by __gconv_path_elem. The locking is not necessary because all calls to __gconv_read_conf (which in turn calls __gconv_get_path) are serialized using __libc_once. This patch: - removes all locking in __gconv_get_path; - replaces all explicitly serialized __gconv_read_conf calls with calls to __gconv_load_conf, a new wrapper that is serialized internally; - adds a new test, iconv/tst-iconv_mt.c, to exercise iconv initialization, usage, and cleanup in a multi-threaded program; - indents __gconv_get_path correctly, removing tab characters (which makes the patch look a little bigger than it really is). After removing the unnecessary locking, it was confirmed that the test case fails if the relevant __libc_once is removed. Additionally, four localedata and iconvdata tests also fail. This gives confidence that the testsuite sufficiently guards against some regressions relating to multi-threading with iconv. Tested on x86_64 and i686. |
