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.
