Add test that detects persistent caches without defaults

The test detects that the following caches miss their defaults:
* comment_context
* gerrit_file_diff
* git_file_diff
* git_modified_files
* git_tags
* groups_byuuid_persisted
* modified_files

They were muted for the time being and defaults will be provided in the
follow up.

Non-blocking and super-fast on-disk cache libModule for Gerrit Code Review based on ChronicleMap on-disk implementation.

How to build

This libModule is built like a Gerrit in-tree plugin, using Bazelisk. See the build instructions for more details.


  • Install cache-chronicalmap module

Install the chronicle-map module into the $GERRIT_SITE/lib directory.

Add the cache-chroniclemap module to $GERRIT_SITE/etc/gerrit.config as follows:

  installModule = com.googlesource.gerrit.modules.cache.chroniclemap.ChronicleMapCacheModule

For further information and supported options, refer to config documentation.
