2013-02-27SNI: ignore captures in server_name regexes when matching by SNI.Valentin Bartenev1-43/+103
This change helps to decouple ngx_http_ssl_servername() from the request object. Note: now we close connection in case of error during server name lookup for request. Previously, we did so only for HTTP/0.9 requests.
2013-02-27Changed interface of ngx_http_validate_host().Valentin Bartenev1-42/+44
2013-02-27Introduced the ngx_http_set_connection_log() macro.Valentin Bartenev3-13/+12
No functional changes.
2013-02-27The default server lookup is now done only once per connection.Valentin Bartenev3-126/+126
Previously, it was done for every request in a connection.
2013-02-27Correctly handle multiple X-Forwarded-For headers (ticket #106).Ruslan Ermilov9-67/+139
2013-02-27Fixed separator in $sent_http_cache_control.Ruslan Ermilov1-6/+27
In case multiple "Cache-Control" headers are sent to a client, multiple values in $sent_http_cache_control were incorrectly split by a semicolon. Now they are split by a comma.
2013-02-23Fixed potential segfault in ngx_http_keepalive_handler().Valentin Bartenev1-0/+1
In case of error in the read event handling we close a connection by calling ngx_http_close_connection(), that also destroys connection pool. Thereafter, an attempt to free a buffer (added in r4892) that was allocated from the pool could cause SIGSEGV and is meaningless as well (the buffer already freed with the pool).
2013-02-23Trailing whitespace fix.Maxim Dounin2-2/+2
2013-02-21Introduced variables in ngx_http_stub_status module.Andrey Belov1-1/+80
Three new variables were added: $connections_active, $connections_reading and $connections_writing.
2013-02-20Connection upgrade support in uwsgi and scgi modules.Maxim Dounin2-2/+18
Prodded by Roberto De Ioris.
2013-02-19Removed zero termination of shm zone names.Valentin Bartenev2-3/+0
It was added in r2717 and no longer needed since r2721, where the termination was added to ngx_shm_alloc() and ngx_init_zone_pool(). So then it only corrupts error messages about ivalid zones.
2013-02-19Version bump.Valentin Bartenev1-1/+1
2013-02-18Proxy: fixed do_write handling in previous commit.Maxim Dounin1-9/+8
As rightfully complained by MSVC, do_write variable was used uninitialized. Correct fix is to set it's initial value based on event happened.
2013-02-18Proxy: support for connection upgrade (101 Switching Protocols).Maxim Dounin8-3/+323
This allows to proxy WebSockets by using configuration like this: location /chat/ { proxy_pass http://backend; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; } Connection upgrade is allowed as long as it was requested by a client via the Upgrade request header.
2013-02-13Fixed false memset warning on Linux with -O3 (ticket #275).Maxim Dounin1-2/+5
Prodded by John Leach.
2013-02-07Version bump.Maxim Dounin1-1/+1
2013-02-04GeoIP: removed pseudo-support of "proxy" and "netspeed" databases.Ruslan Ermilov1-2/+0
2013-02-01FastCGI: proper handling of split fastcgi end request.Maxim Dounin1-7/+37
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).
2013-02-01FastCGI: unconditional state transitions.Maxim Dounin1-49/+8
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.
2013-02-01FastCGI: fixed wrong connection close with fastcgi_keep_conn.Maxim Dounin1-4/+0
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.
2013-02-01Request body: fixed client_body_in_file_only.Maxim Dounin1-1/+17
After introduction of chunked request body reading support in 1.3.9 (r4931), the rb->bufs wasn't set if request body was fully preread while calling the ngx_http_read_client_request_body() function. Reported by Yichun Zhang (agentzh).
2013-01-28Secure_link: fixed configuration inheritance.Ruslan Ermilov1-2/+15
The "secure_link_secret" directive was always inherited from the outer configuration level even when "secure_link" and "secure_link_md5" were specified on the inner level.
2013-01-24GeoIP: IPv6 support.Ruslan Ermilov1-13/+145
When using IPv6 databases, IPv4 addresses are looked up as IPv4-mapped IPv6 addresses. Mostly based on a patch by Gregor Kališnik (ticket #250).
2013-01-22Proxy: fixed proxy_method to always add space.Maxim Dounin1-4/+5
Before the patch if proxy_method was specified at http{} level the code to add trailing space wasn't executed, resulting in incorrect requests to upstream.
2013-01-21Variables $pipe, $request_length, $time_iso8601, and $time_local.Ruslan Ermilov1-0/+102
Log module counterparts are preserved for efficiency. Based on patch by Kiril Kalchev.
2013-01-17Version bump.Ruslan Ermilov1-1/+1
2013-01-16Fixed and improved the "*_bind" directives of proxying modules.Ruslan Ermilov8-12/+131
The "proxy_bind", "fastcgi_bind", "uwsgi_bind", "scgi_bind" and "memcached_bind" directives are now inherited; inherited value can be reset by the "off" parameter. Duplicate directives are now detected. Parameter value can now contain variables.
2013-01-10Fixed "proxy_pass" with IP address and no port (ticket #276).Ruslan Ermilov3-5/+10
Upstreams created by "proxy_pass" with IP address and no port were broken in 1.3.10, by not initializing port in u->sockaddr. API change: ngx_parse_url() was modified to always initialize port (in u->sockaddr and in u->port), even for the u->no_resolve case; ngx_http_upstream() and ngx_http_upstream_add() were adopted.
2012-12-27Geo: improved code readability.Ruslan Ermilov1-54/+61
2012-12-26Upstream keepalive: detect duplicate "keepalive" directive.Ruslan Ermilov1-0/+4
A failure to detect duplicate "keepalive" directive resulted in stack exhaustion.
2012-12-26Version bump.Ruslan Ermilov1-1/+1
2012-12-26Geo: made "default" affect both IPv4 and IPv6 when using prefixes.Ruslan Ermilov1-48/+77
Previously, "default" was equivalent to specifying 0.0.0.0/0, now it's equivalent to specifying both 0.0.0.0/0 and ::/0 (if support for IPv6 is enabled) with the same value.
2012-12-25Geo: properly initialize ngx_cidr_t when dealing with "default".Ruslan Ermilov1-1/+1
2012-12-25Geo: IPv6 support.Ruslan Ermilov1-79/+236
The "ranges" mode is still limited to IPv4 only.
2012-12-25Upstream: fixed state resetting when switching to backup servers.Valentin Bartenev2-2/+6
Based on patch by Thomas Chen (ticket #257).
2012-12-24Fixed HEAD requests handling when proxying is used (closes #261).Valentin Bartenev2-1/+2
2012-12-24Trailing whitespace fix.Ruslan Ermilov1-2/+2
2012-12-23Access log: the "gzip" parameter of the "access_log" directive.Valentin Bartenev1-5/+213
Note: this requires zlib version 1.2.0.4 or above to work.
2012-12-23Access log: the "flush" parameter of the "access_log" directive.Valentin Bartenev1-23/+97
2012-12-23Reopening log files code moved to a separate function.Valentin Bartenev1-19/+71
The code refactored in a way to call custom handler that can do appropriate cleanup work (if any), like flushing buffers, finishing compress streams, finalizing connections to log daemon, etc..
2012-12-23Access log: fixed redundant buffer reallocation.Valentin Bartenev1-5/+9
Previously a new buffer was allocated for every "access_log" directive with the same file path and "buffer=" parameters, while only one buffer per file is used.
2012-12-21Image filter: fixed image_filter rotate inheritance.Maxim Dounin1-9/+15
Configurations like location /i/ { image_filter resize 200 200; image_filter rotate 180; location /i/foo/ { image_filter resize 200 200; } } resulted in rotation incorrectly applied in the location /i/foo, without any way to clear it. Fix is to handle conf->angle/conf->acv consistently with other filter variables and do not try to inherit them if there are transformations defined for current location.
2012-12-21Geo: ensure that default entry is always present.Ruslan Ermilov1-4/+2
If 0.0.0.0/32 entry was present and there was no explicit "default", we failed to add an empty string as a default value.
2012-12-21There's no need to normalize address returned by ngx_ptocidr().Ruslan Ermilov1-1/+1
2012-12-20Image filter: configuration inheritance fixes.Maxim Dounin1-10/+18
The image_filter_jpeg_quality, image_filter_sharpen and "image_filter rotate" were inherited incorrectly if a directive with variables was defined, and then redefined to a literal value, i.e. in configurations like image_filter_jpeg_quality $arg_q; location / { image_filter_jpeg_quality 50; } Patch by Ian Babrou, with minor changes.
2012-12-20Brought the link to ngx_http_perl_module documentation up to date.Ruslan Ermilov1-1/+1
2012-12-19Let "add_header" affect 201 responses (ticket #125).Ruslan Ermilov1-0/+1
2012-12-19Slightly optimized code that handles special headers in "add_header".Ruslan Ermilov1-29/+21
2012-12-18Avoid sending "100 Continue" on 413 Request Entity Too Large.Maxim Dounin1-0/+1
Patch by Igor Sysoev.
2012-12-17Added checks that disallow adding a variable with an empty name.Ruslan Ermilov7-6/+32
Added variable name syntax checks to "geo" and "map" directives.
