Hi Git's community!
I'd like to ask you for some details about "histogram diff" and "libgit"
enhancement/git-merge tasks for this year's GSOC.
Histogram diff:
There is no mentor mentioned in [1]. Does it mean that there is no person
who can be a mentor for this task or is that assignment possible to be
mentored by everyone mentioned in other tasks? I'd like to do this task
very
much. After doing a small observing around source code of git/jgit it looks
feasible for me.
There is a goal "Get this feature merged to the upstream git." -- but I
have
one theoretical question -- what if the benchmarking/study of histogram
diff
leads to conclusion that this algorithm will not be useful for upstream?
Does it mean "fail" in terms of GSOC? I have to think about it even if it
looks that there should be speedup quite obvious. I don't want to fail
a priory :).
libgit2:
I really like the concept of libraries for to be binding-able from dozens
of
languages - this leads to expanding functionality among masses users
almost everywhere. In this part I like the idea of implementing new
features
inside library (diff, config file parsing) but also maybe the task of
merging
libgit2 into git upstream. Basically I don't know much about that.. and
you wrote that this task is more difficult then others, so I probably need
to study git's and libgit's architecture very precisely beforehand .. but
could you tell me some details about that? Is it impossible to do it before
GSOC deadline and is it worth making a serious big efforts to this task
(from your point of view onto project objectives)? How big are requirements
for this task in term of GSOC?
Now it is quite hectic time because of my study :) it's been a long time
since I've had time for myself but I'd like to prepare some patch for to
proof my interests and abilities.

And now not so important part of message (you can skip).. I plan to write
this informations later on to google-melange more precisely.
Something about me || I am:
-- I like C language but there is no problem to study more deeply other
commonly used languages (I need only little brainstorming),
-- interested in Open Source in general, programming (especially in
parallel), chess playing and challenges,
-- student of master's degree BUT (CZ), penultimate year of study, my last
summer :(
-- a fan of Git because of many reasons, I'd like to become a contributor
even
if the GSOC opportunity wont come.
-- not so good English speaker so sometimes my messages could be a little
harder to understand.
Experiences:
In most cases I have only school projects experiences (even if programming
projects are some kind of evergreen here in Brno). But I've had one Open
Source experience -- enhancement for Daniel Stenberg's libcurl [2] followed
with some continuing patches. The main patch implements shell-like wildcard
pattern matching functionality for FTP protocol and makes an enhancement of
API to allow implementing of this functionality among other protocols.
(I've done implementation of wildcard "*.txt, [a-z]???.txt" compiler, auto
testing script, enhancement for testing FTP server inside libcurl, man
pages,
.. )
The most difficult part was to understand how it works inside curl library
-- but now I think I'm better in that aspect so I think I can make some
useful
work for Git too.

Don't worry please, my next messages will be much briefer :)
