2013-02-11Merge of r5027, r5028, r5029: fastcgi_keep_conn fixes.Maxim Dounin1-58/+43
*) FastCGI: fixed wrong connection close with fastcgi_keep_conn. With fastcgi_keep_conn it was possible that connection was closed after FCGI_STDERR record with zero padding and without any further data read yet. This happended as f->state was set to ngx_http_fastcgi_st_padding and then "break" happened, resulting in p->length being set to f->padding, i.e. 0 (which in turn resulted in connection close). Fix is to make sure we continue the loop after f->state is set. *) FastCGI: unconditional state transitions. Checks for f->padding before state transitions make code hard to follow, remove them and make sure we always do another loop iteration after f->state is set to ngx_http_fastcgi_st_padding. *) FastCGI: proper handling of split fastcgi end request. If fastcgi end request record was split between several network packets, with fastcgi_keep_conn it was possible that connection was saved in incorrect state (e.g. with padding bytes not yet read).
2013-02-10Merge of r4948, r4949, r4964, r4973, r5011: variables.Maxim Dounin1-1/+1
*) Allow the complex value to be defined as an empty string. This makes conversion from strings to complex values possible without the loss of functionality. *) The "auth_basic" directive gained support of variables. *) Fixed variable syntax checking in "set", "geo", "limit_conn_zone", and "perl_set" directives. *) Added checks that disallow adding a variable with an empty name. Added variable name syntax checks to "geo" and "map" directives. *) Variables $pipe, $request_length, $time_iso8601, and $time_local. Log module counterparts are preserved for efficiency. Based on patch by Kiril Kalchev.
2012-09-24Merge of r4785, r4795, r4811, r4812, r4816, r4822: coverity.Maxim Dounin1-0/+3
*) Resolver: fixed possible memory leak in ngx_resolver_create(). *) Explicitly ignore returned value from unlink() in ngx_open_tempfile(). *) Explicitly ignore returned value from close() in ngx_event_core_init_conf(). *) Added three missing checks for NULL after ngx_array_push() calls. *) Crypt: fixed handling of corrupted SSHA entries in password file. *) Mark logically dead code with corresponding comment. Found by / prodded by Coverity.
2012-06-04Merge of r4617: fastcgi padding fix.Maxim Dounin1-4/+23
Fastcgi: fixed padding handling on fixed-size records. Padding was incorrectly ignored on end request, empty stdout and stderr fastcgi records. This resulted in protocol desynchronization if fastcgi application used these records with padding for some reason. Reported by Ilia Vinokurov.
2012-06-04Merge of r4616: r->state fix.Maxim Dounin1-0/+3
Added r->state reset on fastcgi/scgi/uwsgi request start. Failing to do so results in problems if 400 or 414 requests are redirected to fastcgi/scgi/uwsgi upstream, as well as after invalid headers got from upstream. This was already fixed for proxy in r3478, but fastcgi (the only affected protocol at that time) was missed. Reported by Matthieu Tourne.
2012-04-12Fixed grammar in error messages.Ruslan Ermilov1-7/+7
2012-03-15Fixed incorrect ngx_cpystrn() usage in ngx_http_*_process_header().Maxim Dounin1-4/+4
This resulted in a disclosure of previously freed memory if upstream server returned specially crafted response, potentially exposing sensitive information. Reported by Matthew Daley.

2011-11-14Fixed fastcgi/scgi/uwsgi_param inheritance.Maxim Dounin1-30/+58
The following problems were fixed: 1. Directive fastcgi_cache affected headers sent to backends in unrelated servers / locations (see ticket #45). 2. If-Unmodified-Since, If-Match and If-Range headers were sent to backends if fastcgi_cache was used. 3. Cache-related headers were sent to backends if there were no fastcgi_param directives and fastcgi_cache was used at server level.

2011-09-15Keepalive support in fastcgi.Maxim Dounin1-7/+69
By default follow the old behaviour, i.e. FASTCGI_KEEP_CONN flag isn't set in request and application is responsible for closing connection once request is done. To keep connections alive fastcgi_keep_conn must be activated.
