This can be useful when working on the support for private jenkins, since many
of those changes can only be tested as a pull request, and they also tend to
include a lot of commits (because nothing can be tested locally).
So until whatever needs implementing for private jenkins is complete and
working, there's no need for the public bots to do anything for such pull
requests.
A few general categories of fixes:
* Sprinkle lots of quotes everywhere.
* Don't use environment variables in the format string to printf, instead pass them as arguments.
* Don't use backticks to execute commands (it's deprecated), use the new "$(...)" syntax instead.
* [jenkins] Create comment file for PR builds. (#3799)
* [jenkins] Create comment file for PR builds.
* [tools] Create stamp file after doing things that might modify files we care about. (#3864)
We have consistency checks to verify that no unexpected files are modified
done when comparing APIs in for a pull request.
Unfortunately the check didn't take into account that checking out the
revision to do the API check against might modify some of the files in the
consistency check itself, thus triggering the consistency check.
Fix this by only verify timestamps of files modified after checkout out the
revision, which is the only thing we care about anyway.
For examples see PR #3855 or PR #3850.
* [jenkins] Don't succeed if something went wrong when creating API or generator diff. (#3865)
