annotate src/os/unix/ngx_thread_cond.c @ 7605:02a539522be4
Tolerate '\0' in URI when mapping URI to path.
If a rewritten URI has the null character, only a part of URI was
copied to a memory buffer allocated for path. In some setups this
could be exploited to expose uninitialized memory via the Location
header.
