nginx.git/src/http/modules/ngx_http_limit_conn_module.c, branch release-1.28.3

Limit conn: added shared context.

2019-11-18T16:50:59+00:00

Previously only an rbtree was associated with a limit_conn.  To make it
possible to associate more data with a limit_conn, shared context is introduced
similar to limit_req.  Also, shared pool pointer is kept in a way similar to
limit_req.

Limit conn: $limit_conn_status variable.

2019-11-18T14:48:32+00:00

The variable takes one of the values: PASSED, REJECTED or REJECTED_DRY_RUN.

Limit conn: limit_conn_dry_run directive.

2019-11-19T08:30:41+00:00

A new directive limit_conn_dry_run allows enabling the dry run mode.  In this
mode connections are not rejected, but reject status is logged as usual.

Fixed logging.

Limit conn: aligned field names in structures.

2014-09-24T17:55:19+00:00

No functional changes.

Limit conn: use complex value in limit_conn_zone (ticket #121).

2014-09-24T17:55:19+00:00

One intentional side effect of this change is that key is allowed only
in the first position.  Previously, it was possible to specify the key
variable at any position, but that was never documented, and is contrary
to nginx configuration practice for positional parameters.

Limit conn: removed deprecated "limit_zone" directive.

2014-09-24T17:55:19+00:00

It's deprecated since 260d591cb6a3 (1.1.8).  The "limit_conn_zone" directive
should be used instead.

The limit_req_status and limit_conn_status directives.

2013-03-18T14:50:29+00:00

Patch by Nick Marden, with minor changes.

Added checks that disallow adding a variable with an empty name.

2012-12-17T19:03:33+00:00

Added variable name syntax checks to "geo" and "map" directives.

Fixed variable syntax checking in "set", "geo", "limit_conn_zone",

2012-12-13T15:05:19+00:00

and "perl_set" directives.
