This module provides a way to generate universally unique identifiers (UUID) as specified in RFC 4122. The UUID is provided as a string representation by reading the $uuid pseudo-variable or calling the uuid() script function.
The $uuid variable returns a newly generated version 4 UUID based on high-quality randomness from /dev/urandom, if available. Otherwise, a version 1 UUID (based on current time and the local ethernet MAC address) will be generated.
Generates a new UUID.
out_var - an output variable to return the generated UUID.
version (optional) - UUID version number. The supported values are:
0 - a RFC version 4 or version 1 UUID will be generated, depending on the availability of high-quality randomness from /dev/urandom. This is the default behavior, if the version parameter is missing.
1 - version 1 UUID based on current time and the local ethernet MAC address
4 - version 4 UUID based on a high-quality random number generator. If not available, a pseudo-random generator will be substituted.
If UUID version 1 is used, the function will return the value 2 if the UUID was generated in an unsafe manner. This refers to the posibility of two concurrently running processes generating the same UUID, in cases where synchronization mechanisms are not available (more details can be found in the uuid_generate man pages of libuuid).
This function can be used from any route.
Table 2.1. Top contributors by DevScore(1), authored commits(2) and lines added/removed(3)
(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
