Subject [jira] [Commented] (INFRA-18499) Migrate primary VCS from SVN to Git for Apache JMeter
Date Mon, 17 Jun 2019 15:09:00 GMT


Vladimir Sitnikov commented on INFRA-18499:

> What is the problem you are trying to achieve

Daniel, we have a bunch of jar files in the repository (see id, size, name below) which were
created and removed "long ago".
Those blobs still count towards the repository size, and those increase fork size/download
size for everybody (people often tend to use full clones).

So I'm trying to minimize the repository size. Of course the saving of 1.5M is not tremendous,
however we are 4 trivial commits past "cleanup" migration, so it is not like I'm trying to
rewrite "the whole history" for the sake of saving 1.5M.

The amount of "rewritten" history would be 4 trivial commits. The rest is kept in SVN anyway.

The js.jar was removed in 2009, and I see no reason I could delete the blob by adding more
Git commits:

> There's an agreement to migrate from SVN to GitBox for Apache JMeter.
> Here's the vote thread:
> One of the ideas is to cleanup Git repository as a part of migration (e.g. remove accidentally
committed multi-megabyte jar files)
> Can you please clarify if that is a viable approach?
> My understanding is that it is valid to alter history (e.g. remove unrelated files) during
SVN->Git migration.
> Note: I do understand that "GitHub pull requests will need to be rebased", so the question
is more like "are there limitations on history edits during migration?"
> Current SVN:
> Desired Git:
> "git cleanup" is an automatic script:
> The result is as follows:
> As far as I understand, the process is as follows:
> * JMeter committers settle on a timeframe so they do not commit to SVN/Git repositories
> * Infra disables SVN->Git sync
> * Infra disables mail notifications for
> * Infra makes SVN repository a read-only one
> * Infra (or someone from JMeter comitters?) populates
> * Infra enables mail notifications for
