Module description


1.2.1.OpenSIPS Modules

The following modules must be loaded before this module:

  • No dependencies on other OpenSIPS modules.

1.2.2.External Libraries or Applications

The following libraries or applications must be installed before running OpenSIPS with this module loaded:

  • PostgreSQL library - e.g., libpq5.

  • PostgreSQL devel library - to compile the module (e.g., libpq-dev).

1.3.Exported Parameters

1.3.1.exec_query_threshold (integer)

If queries take longer than 'exec_query_threshold' microseconds, warning messages will be written to logging facility.

Default value is 0 - disabled.

Example1.1.Set exec_query_threshold parameter

modparam("db_postgres", "exec_query_threshold", 60000)

1.3.2.max_db_queries (integer)

The maximum number of database queries to be executed. If this parameter is set improperly, it is set to default value.

Default value is 2.

Example1.2.Set max_db_queries parameter

modparam("db_postgres", "max_db_queries", 2)

1.4.1.timeout (integer)

The number of seconds the PostgreSQL library waits to connect and query the server. If the connection does not succeed within the given timeout, the connection fails.

Note:If the timeout is a negative value and connection does not succeed, OpenSIPS will block until the connection becomes back available and gets successfully established. This is the default behavior of the library and is the behavior prior to the adition of this parameter.

Default value is 5.

Example1.3.Set timeout parameter

modparam("db_postgres", "timeout", 2)

1.5.Exported Functions


1.6.Installation and Running

(1) DevScore = author_commits + author_lines_added / (project_lines_added / project_commits) + author_lines_deleted / (project_lines_deleted / project_commits)

(2) including any documentation-related commits, excluding merge commits. Regarding imported patches/code, we do our best to count the work on behalf of the proper owner, as per the "fix_authors" and "mod_renames" arrays in opensips/doc/build-contrib.sh. If you identify any patches/commits which do not get properly attributed to you, please submit a pull request which extends "fix_authors" and/or "mod_renames".

(3) ignoring whitespace edits, renamed files and auto-generated files
