Add script to bump up version on bleeding edge.
The version.cc file will from now on be controlled on bleeding edge and on trunk. The next version to use will always be max(bleeding_edge_version, trunk_version) + 1. The trunk and bleeding_edge versions are not semantically tied together. The trunk branch can be used to make independent point releases of bleeding_edge revisions. The version on bleeding_edge will be increased if: - the lkgr version is smaller than the version of the latest revision, - the lkgr version is not a version change itself, - the tree is not closed for maintenance. This will allow chromium to refer directly to bleeding_edge revisions of v8. The v8 versions will not be unique, but they will change as often as possible, dependent on the lkgr cycle time and the frequency this script is called.

Script for auto-increasing the version on bleeding_edge.
|
||||
|
||||
The script can be run regularly by a cron job. It will increase the build
|
||||
level of the version on bleeding_edge if:
|
||||
- the lkgr version is smaller than the version of the latest revision,
|
||||
- the lkgr version is not a version change itself,
|
||||
- the tree is not closed for maintenance.
|
||||
|
||||
The new version will be the maximum of the bleeding_edge and trunk versions +1.
|
||||
E.g. latest bleeding_edge version: 3.22.11.0 and latest trunk 3.23.0.0 gives
|
||||
the new version 3.23.1.0.
|
||||
|
||||
This script requires a depot tools git checkout. I.e. 'fetch v8'.
