Re: [jgit-dev] Shallow clone using JGit
|
Support for shallow clones is coming along bit by bit I think - JGit can now serve shallow clones (ie when used in server mode) and apparently RevWalk now supports traversing shallow clones:
However, I don't think the JGit library currently supports doing a shallow clone as a client - if you look at the JGit CloneCommand, there's no sign of it:
I used to miss this feature too, but I've come to be less convinced of it's use - what do you feel it's useful for? For a reasonably 'sane' repo (one that has slowly grown over time) the brilliant packfile storage format means that saving on transmitted data (between shallow and non-shallow) is often less than 10% - so is the shallow clone worth the hassle?
For a repo that is relatively sane now (but had a psychotic episode a few years back when someone checked in a big file) the savings will be better - the shallow clone will mean you probably don't have to download that massive blob - but if the repo is under your control, it's probably just better to clean the repo history up using git-filter-branch or similar, so that everyone gets the benefit of a saner history.
best regards,
Roberto
