[jgit-dev] Writing list method using JGit

["ilya.ivanov@xxxxxxxxxxx" <ilya.ivanov@xxxxxxxxxxx>]

Hi!

Sorry, if it's not a correct place for the question.

I'm writing method that should list children of one tree in git repo. 
For each entry (file/dir) it must get info about last changed version, 
author, modification date (like github repo browser shows).
My implementation does the following:

1. Gets list of directory children (using TreeWalk). I will call this 
list <interesting paths>

2. Creating RevWalk. Traversing through commits and searching where each 
file was last changed.
For every commit returned by RevWalk I create a TreeWalk for two trees: 
from current commit and from previous commit. This allows to find paths 
changed in current commit.
If I find that one of <interesting paths> is changed between two commits 
I take commit info for that path.

Could you suggest some optimization for that? What can be the bottleneck 
in this implementation?
I think comparing paths in takes lot of time, but have no idea how to 
improve it. I tried to use PathFilterGroup

This algorithm must be as fast as possible.

Thanks,
Ilya
