2011-11-14Introduction of simple ngx_write_stderr() instead of ngx_log_stderr()Igor Sysoev4-18/+38
for output of ./configure options, etc., since ngx_log_stderr() output length is limited by 2048 characters defined as NGX_MAX_ERROR_STR.
2011-11-14Fix of "Content-Length" header of MP4 response if start argument was used.Igor Sysoev1-1/+2
Patch by Piotr Sikora.
2011-11-14Renamed ngx_http_limit_zone_module to ngx_http_limit_conn_module.Valentin Bartenev2-103/+103
2011-11-14Reverted incorrect change in internal md5 (part of r3928).Maxim Dounin1-1/+2
2011-11-14Fixed fastcgi/scgi/uwsgi_param inheritance.Maxim Dounin3-90/+174
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.
2011-11-14Separate functions to merge fastcgi/scgi/uwsgi params.Maxim Dounin3-87/+123
No functional changes.
2011-11-14Fixed Upgrade header clearing with proxy_cache.Maxim Dounin1-0/+1
This was missed in proxy HTTP/1.1 support commit (r4127).
2011-11-14Fixed proxy_set_header inheritance with proxy_set_body.Maxim Dounin1-17/+12
2011-11-14Fixed proxy_set_header inheritance with proxy_cache (ticket #45).Maxim Dounin1-9/+23
Headers cleared with cache enabled (If-Modified-Since etc.) might be cleared in unrelated servers/locations without proxy_cache enabled if proxy_cache was used in some server/location. Example config which triggered the problem: proxy_set_header X-Test "test"; server { location /1 { proxy_cache name; proxy_pass ... } } server { location /2 { proxy_pass ... } } Another one: server { proxy_cache name; location /1 { proxy_pass ... } location /2 { proxy_cache off; proxy_pass ... } } In both cases If-Modified-Since header wasn't sent to backend in location /2. Fix is to not modify conf->headers_source, but instead merge user-supplied headers from conf->headers_source and default headers (either cache or not) into separate headers_merged array.
2011-11-14Fixed NGX_CONF_TAKE1/NGX_CONF_FLAG misuse.Sergey Budnevitch4-5/+5
2011-11-10Limit zone: added the "limit_conn_zone" directive.Valentin Bartenev1-3/+132
It supersedes old "limit_zone" directive (deprecated accordingly) and uses syntax consistent with the "limit_req_zone" directive.
2011-11-10Limit zone: support for multiple "limit_conn" limits.Valentin Bartenev1-73/+117
2011-11-10Limit zone: rbtree lookup moved to a separate function.Valentin Bartenev1-51/+73
No functional changes.
2011-11-10Changed error message to be more appropriate in the imaginaryRuslan Ermilov1-1/+1
"open_file_cache max=0" case.
2011-11-09Fixed compression pointer processing in DNS response greater than 255 bytes.Igor Sysoev1-7/+7
Thanks to Ben Hawkes.
2011-11-08Fix of "keepalive_disable" directive.Igor Sysoev1-6/+8
2011-11-08The "image_filter_sharpen" directive.Igor Sysoev1-1/+71

2011-11-01Version bump.Igor Sysoev2-3/+3
2011-10-31Silently ignoring a stale global SSL error left after disabled renegotiation.Igor Sysoev1-0/+7
2011-10-31Fixed segfault on configuration testing with ssl (ticket #37).Maxim Dounin1-1/+10
The following config caused segmentation fault due to conf->file not being properly set if "ssl on" was inherited from the http level: http { ssl on; server { } }
2011-10-31Event pipe: reduced number of file buffers used.Maxim Dounin2-22/+55
If possible we now just extend already present file buffer in p->out chain instead of keeping ngx_buf_t for each buffer we've flushed to disk. This saves about 120 bytes of memory per buffer flushed to disk, and resolves high CPU usage observed in edge cases (due to coalescing these buffers on send).
2011-10-31Event pipe: fixes for complex protocols.Maxim Dounin1-63/+20
1. In ngx_event_pipe_write_chain_to_temp_file() make sure to fully write all shadow buffers up to last_shadow. With this change recycled buffers cannot appear in p->out anymore. This also fixes segmentation faults observed due to ngx_event_pipe_write_chain_to_temp() not freeing any raw buffers while still returning NGX_OK. 2. In ngx_event_pipe_write_to_downstream() we now properly check for busy size as a size of buffers, not a size of data in these buffers. This fixes situations where all available buffers became busy (including segmentation faults due to this). 3. The ngx_event_pipe_free_shadow_raw_buf() function is dropped. It's incorrect and not needed.

2011-10-24malloc() debugging on MacOSX.Igor Sysoev13-9/+48
2011-10-24FreeBSD's MALLOC_OPTIONS must be set before any malloc() call.Igor Sysoev1-4/+4
The bug has been introduced in r3799.
2011-10-21Fixed another return in unix ngx_write_chain_to_file().Maxim Dounin1-2/+9
Previous patch missed special case for one iovec, it needs total bytes written to be returned as well.
2011-10-20Fixed unix ngx_write_chain_to_file() to return total bytes written.Maxim Dounin1-2/+5
Previously result of last iteration's writev() was returned. This was unnoticed as return value was only used if chain contained only one or two buffers.

Patch by Alexey Kuts.
2011-10-13Skipping location rewrite phase for server null location.Igor Sysoev1-0/+12
2011-10-12Better recheck of dead upstream servers.Maxim Dounin3-8/+18
Previously nginx used to mark backend again as live as soon as fail_timeout passes (10s by default) since last failure. On the other hand, detecting dead backend takes up to 60s (proxy_connect_timeout) in typical situation "backend is down and doesn't respond to any packets". This resulted in suboptimal behaviour in the above situation (up to 23% of requests were directed to dead backend with default settings). More detailed description of the problem may be found here (in Russian): http://mailman.nginx.org/pipermail/nginx-ru/2011-August/042172.html Fix is to only allow one request after fail_timeout passes, and mark backend as "live" only if this request succeeds. Note that with new code backend will not be marked "live" unless "check" request is completed, and this may take a while in some specific workloads (e.g. streaming). This is believed to be acceptable.
2011-10-12Clear old Location header (if any) while adding a new one.Maxim Dounin5-0/+17
This prevents incorrect behaviour when another redirect is issued within error_page 302 handler.
2011-10-12Wording fix, "many data" is incorrect.Maxim Dounin1-1/+1
Noted by Piotr Sikora.

2011-10-12Removed old warning that suggested to use "server_name_in_redirect off"Ruslan Ermilov1-7/+0
(now the default) in place of no longer supported "server_name *".
2011-10-11Additional headers for proxy/fastcgi/uwsgi/scgi_ignore_headers.Maxim Dounin2-6/+29
Now the following headers may be ignored as well: X-Accel-Limit-Rate, X-Accel-Buffering, X-Accel-Charset.
