Adapt to the removal of cache diff

The "diff" cache has been removed in stable-3.5 (I52738c85), in favour
of two new caches, the git_file_diff cache (introduced in  Ia278881c0f)
and the gerrit_file_diff cache (introduced in I23f616d1).

Adapt the migration servlet accordingly and adjust the tests
expectations.

Persistent cache for Gerrit, based on ChronicleMap

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.

Setup

  • 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:

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

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