annotate src/core/ngx_murmurhash.c @ 634:23ef0645ea57 NGINX_1_1_1
nginx 1.1.1
*) Change: now cache loader processes either as many files as specified
by "loader_files" parameter or works no more than time specified by
"loader_threshold" parameter during each iteration.
*) Change: now SIGWINCH signal works only in deamon mode.
*) Feature: now shared zones and caches use POSIX semaphores on
Solaris.
Thanks to Den Ivanov.
*) Feature: accept filters are now supported on NetBSD.
*) Bugfix: nginx could not be build on Linux 3.0.
*) Bugfix: nginx did not use gzipping in some cases; the bug had
appeared in 1.1.0.
*) Bugfix: request body might be incorrectly processed if client used
pipelining.
*) Bugfix: in the "request_body_in_single_buf" directive.
*) Bugfix: in "proxy_set_body" and "proxy_pass_request_body" directives
if SSL connection to backend was used.
*) Bugfix: nginx hogged CPU if all servers in an upstream were marked
as "down".
*) Bugfix: a segmentation fault might occur during reconfiguration if
ssl_session_cache was defined but not used in a previous
configuration.
*) Bugfix: a segmentation fault might occur in a worker process if many
backup servers were used in an upstream.
*) Bugfix: a segmentation fault might occur in a worker process if
"fastcgi/scgi/uwsgi_param" directives were used with values starting
with "HTTP_"; the bug had appeared in 0.8.40.
