Distribution size

[Marc Weber]

Hi,

Has anyone thought about reducing distribution size ?

comparison:

git-1.6.4.4 i%du -hs .
115M    .

mercurial-1.0.2 i%du -hs .
5.4M    .

bazaar-1.10rc1 i%du -hs
21M     .

darcs-2.2.1 i%du -hs    /nix/store/8xwfavyv22pvm3s60wvzcbq561fjk5di-darcs-2.2.1 nixos   
32M	.

There was an attempt to reduce size by using a shared library in 2007:

So is there a reason why git takes up so much more disk space other than
that its using many small executables?

Funny.  Git for Windows is less than 12MB [*1*].  And it includes a bash 
and Perl.  (Did you count Python on Windows?)

So maybe your analysis is severely borked.

Well, the portable Git bundle compressed with 7zip is approx. 11MB, the Git
installer (maybe also using 7zip internally) is at approx. the same size.
Unpacked/installed on disk they are at 138MB/131MB. If you try to compress
it with zip, it will reduce to approx. 70MB which still is quite large.

We are interested, too, in having a small(er) bundle, because we want to
distribute Git binaries with our Git GUI front-end, SmartGit, so the user
will (have the option to) get an all-inclusive-bundle.

Of course, the Git installer does nothing like you claim.

If I see something in it for myself, I might want to help.

[Please, never ever top-post on the Git mailing list, thanks]

Most of the git-*.exe are identical duplicates, so most of that can be 
nuked. Also, you don't need everything in msysgit to distribute, only 
for development. You should be able to make a fairly small 
distribution for usage only.

Hi Marius,

How should I find out what is required to *run* all git commands, except of
trying it myself? Is there a document available somewhere?

Thomas, are you seriously asking to work for you for free?  What's in it 
for us?

Errr... what?

  $ du -hs /usr/libexec/git-core/
  8.0M

  $ du -shc `rpm -ql git`
  ...
  27M
 
But

  $ du -sh git/.git
  49M

(there is some of my commits there, some old branches pinned, and some
commits with other git(web) forks).

And

  $ git archive HEAD --output=tmp.tar
  $ du -sh tmp.tar 
  11M     tmp.tar

Are you sure you are comparing the same thing in all cases?
And not in some cases after "make", with all object files?

perhaps it's due to usage of hard links?
