I know this has come up a few times in the past but I wanted to bring this up again.
The lucene-solr ASF git mirror has been behind by about a day. I was speaking with the infra people and they say that the size of the repo needs more and more ram. Forcing a sync causes a fork-bomb: Can't fork: Cannot allocate memory at /usr/share/perl5/Git.pm line 1517. They tried a few things but it's almost certain that it needs even more RAM, which still is a band-aid as they'd soon need even more RAM. Also, adding RAM involves downtime for git.a.o which needs to be planned. As a stop gap arrangement attached a volume to the instance and are using it as swap to work around the "adding RAM requires restart" issue. FAQ: How would the memory requirement change if we moved to git instead of mirroring? Answer: svn -> git mirroring is a weird process and has quite the memory leak. Using git directly is much cleaner. I personally think git does make things easier to manage when you're working on multiple overlapping things and so we should re-evaluate moving to it. I would have been fine had the mirroring worked, as all I want is a way to be able to work on multiple (local) branches without having to create and maintain directories like: lucene-solr-trunk1, lucene-solr-trunk2, or SOLR-XXXX, etc. Opinions? -- Anshum Gupta
