AbstractChangeNotes: Lazily create RevWalk In the common case where there is a ChangeNotesCache hit, we only need the meta ID from the LoadHandle and not the RevWalk. Creating RevWalks is cheap, but it's not free. For example, it creates an ObjectIdOwnerMap which allocates two object arrays of size 1024 and 2048, totaling several KiB. A loaded server may have hundreds of ChangeNotesCache hits per second, adding up to megabytes per second of completely unused garbage. This isn't just theoretical: I observed megabytes of garbage being generated by this path in a live frontend. Change-Id: I583a3f5cac8b7be4832d49cf8cbdea54b1b3bf8e
Gerrit is a code review and project management tool for Git based projects.
Gerrit makes reviews easier by showing changes in a side-by-side display, and allowing inline comments to be added by any reviewer.
Gerrit simplifies Git based project maintainership by permitting any authorized user to submit changes to the master Git repository, rather than requiring all approved changes to be merged in by hand by the project maintainer.
For information about how to install and use Gerrit, refer to the documentation.
Our canonical Git repository is located on googlesource.com. There is a mirror of the repository on Github.
Please report bugs on the issue tracker.
Gerrit is the work of hundreds of contributors. We appreciate your help!
Please read the contribution guidelines.
Note that we do not accept Pull Requests via the Github mirror.
The IRC channel on freenode is #gerrit. An archive is available at: echelog.com.
The Developer Mailing list is repo-discuss on Google Groups.
Gerrit is provided under the Apache License 2.0.
