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.
2012-12-14Geo: fixed the "ranges" without ranges case.Ruslan Ermilov1-15/+18
The following configuration returned an empty value for $geo: geo $geo { ranges; default default; }
2012-12-14Geo: improved ngx_http_geo_block() code readability.Ruslan Ermilov1-3/+2
2012-12-14Gzip: fixed zlib memLevel adjusting.Valentin Bartenev1-0/+4
An incorrect memLevel (lower than 1) might be passed to deflateInit2() if the "gzip_hash" directive is set to a value less than the value of "gzip_window" directive. This resulted in "deflateInit2() failed: -2" alert and an empty reply.
2012-12-13Upstream: fixed SIGSEGV with the "if" directive.Maxim Dounin1-0/+8
Configuration like location / { set $true 1; if ($true) { proxy_pass http://backend; } if ($true) { # nothing } } resulted in segmentation fault due to NULL pointer dereference as the upstream configuration wasn't initialized in an implicit location created by the last if(), but the r->content_handler was set due to first if(). Instead of committing a suicide by dereferencing a NULL pointer, return 500 (Internal Server Error) in such cases, i.e. if uscf is NULL. Better fix would be to avoid such cases by fixing the "if" directive handling, but it's out of scope of this patch. Prodded by Piotr Sikora.
2012-12-13Fixed variable syntax checking in "set", "geo", "limit_conn_zone",Ruslan Ermilov4-4/+11
and "perl_set" directives.
2012-12-13Proxy: better error message about unexpected data.Maxim Dounin1-1/+2
Requested by Igor Sysoev.
2012-12-12Limit rate: fixed integer overflow in limit calculation (ticket #256).Valentin Bartenev1-1/+1
Patch by Alexey Antropov.
2012-12-10The "auth_basic" directive gained support of variables.Ruslan Ermilov1-47/+36
2012-12-06Allow the complex value to be defined as an empty string.Ruslan Ermilov8-18/+14
This makes conversion from strings to complex values possible without the loss of functionality.
2012-12-06Xslt: prevented infinite loop.Ruslan Ermilov1-2/+2
If XSLT transformation failed and error 500 was handled in the same location, an infinite loop occured that exhausted the stack.
2012-12-03Fixed build with embedded perl in certain setups (ticket #48).Ruslan Ermilov1-14/+3
2012-11-29Version bump.Maxim Dounin1-1/+1
2012-11-26Gunzip: added missing ngx_http_clear_etag().Maxim Dounin1-0/+1
2012-11-26Request body: block write events while reading body.Maxim Dounin1-0/+2
If write events are not blocked, an extra write event might happen for various reasons (e.g. as a result of a http pipelining), resulting in incorrect body being passed to a post handler. The problem manifested itself with the dav module only, as this is the only module which reads the body from a content phase handler (in contrast to exclusive content handlers like proxy). Additionally, dav module used to dump core in such situations due to ticket #238. See reports here: http://mailman.nginx.org/pipermail/nginx-devel/2012-November/002981.html http://serverfault.com/questions/449195/nginx-webdav-server-with-auth-request
2012-11-26Request body: error checking fixes, negative rb->rest handling.Maxim Dounin1-2/+11
Negative rb->rest can't happen with current code, but it's good to have it handled anyway. Found by Coverity (CID 744846, 744847, 744848).
2012-11-26Request body: improved handling of incorrect chunked request body.Maxim Dounin2-5/+16
While discarding chunked request body in some cases after detecting request body corruption no error was returned, while it was possible to correctly return 400 Bad Request. If error is detected too late, make sure to properly close connection. Additionally, in ngx_http_special_response_handler() don't return body of 500 Internal Server Error to a client if ngx_http_discard_request_body() fails, but disable keepalive and continue.
