diff src/http/modules/ngx_http_limit_zone_module.c @ 356:b743d290eb3b NGINX_0_6_22
nginx 0.6.22
*) Change: now all ngx_http_perl_module methods return values copied to
perl's allocated memory.
*) Bugfix: if nginx was built with ngx_http_perl_module, the perl
before 5.8.6 was used, and perl supported threads, then during
reconfiguration the master process aborted; bug appeared in
0.5.9.
Thanks to Boris Zhmurov.
*) Bugfix: the ngx_http_perl_module methods may get invalid values of
the regex captures.
*) Bugfix: a segmentation fault occurred in worker process, if the
$r->has_request_body() method was called for a request whose small
request body was already received.
*) Bugfix: large_client_header_buffers did not freed before going to
keep-alive state.
Thanks to Olexander Shtepa.
*) Bugfix: the last address was missed in the $upstream_addr variable;
bug appeared in 0.6.18.
*) Bugfix: the "fastcgi_catch_stderr" directive did return error code;
now it returns 502 code, that can be rerouted to a next server using
the "fastcgi_next_upstream invalid_header" directive.
*) Bugfix: a segmentation fault occurred in master process if the
"fastcgi_catch_stderr" directive was used; bug appeared in
0.6.10.
Thanks to Manlio Perillo.
