gitweb / cg-export

gitweb / cg-export

[Toby White]

I was wondering if a feature like the following would be of
use to anyone except me: I'd like to be able to download
the full source of a given tree from gitweb.

Use cases:

a) I'm browsing history through gitweb, find the tree
I'm interested in & want to download the whole tree without
cutting and pasting hashes.

b) I want to be able to quickly let people grab my latest
revision who don't have git installed, without faffing
about creating tarballs & emailing them; I'd like to be
able to paste a URL straight into my IM client.

I've quickly hacked gitweb to do this for me - patch below.

It adds an extra link to the 'commit' page. Next to the link
that would lead you to 'tree', there is 'tar.gz' which simply
returns the tar.gz of the same tree.

The patch is against the version of gitweb currently in
Debian, which is, erm, '264-1', apparently, because that's
what I had to hand.

Anyway. I'm no git expert so perhaps this is a really bad
idea, but I find it useful.

Argh - sorry, patch got mangled somehow in previous message.

Correct patch below.

So you want to have snapshot of a tree. Why not snapshot of a commit, 
or of a tag?

It is really better to hack git with git. And you can use current gitweb
with old git (well, not always, as current gitweb requires --full-history
option to git-rev-list to be available).

It is usefull idea, as it was implemented independently by Sven Verdoolaege
in http://marc.theaimsgroup.com/?l=git&m=111909432415478&w=2 directly in
gitweb, and by Sham Chukoury in gitweb-xmms2 using snapshot.cgi in Python
in "Snapshot links support" commit
http://git.xmms.se/?p=gitweb-xmms2.git;a=commit;h=3d0284bb784041907de33df5cff8449f8aeb072e
and "Add xmms2 project's snapshot.cgi" commit
http://git.xmms.se/?p=gitweb-xmms2.git;a=commit;h=3d0284bb784041907de33df5cff8449f8aeb072e

I have planned to add snapshot support, see "[RFC] gitweb wishlist and TODO
list" thread in mailing list archives, check
   http://git.or.cz/gitwiki/GitCommunity
for list, but I was planning to do some refactoring, including 
<td class="link"> links refactoring (that is where snapshot links would be
added).

Add it to git_commit too. The patch contains the pervious changes also.

It might be better to use -6 (the default compression/speed trade-off)
instead of using -9 (best but slowest compression) here.  Or maybe
even make it configurable. On some servers it is probably preferable
to make the snapshot (slightly) larger and gain some cpu time.

To get some numbers I made a small benchmark with the current git
tree. I get the following on my machine:

Compression/speed    Size   Time
-1                   1.1M   0.16s
-6                   923K   0.36s
-9                   917K   0.50s

This looks Ok (except "$project" needs to be shell quoted on the
pipe-open line and possibly in the URL; there may be some other
minor details I missed).  It needs to be protected by elective,
opt-in configuration variable, similarly to how "blame" is done,
since I suspect this would be rather expensive.

These -Mixed-Case, '-sometimes-quoted', spaces sometimes around
double-arrow sometimes missing, parameters bother me.  Perhaps:

	print $cgi->header(-type => 'application/x-tar',
                           -content-encoding => 'x-gzip',
                           -content-disposition =>
                               "inline; filename=\"$project.tar.gz\"",
                           -status => '200 OK');

RFC 2616 says that "gzip" content-coding is registered with
IANA, so I do not think you need to say "x-gzip".

> +	open my $fd, "-|", "$GIT tar-tree $hash \'$project\' | gzip -c6" or die_error(undef, "Execute git-tar-tree failed.");

I think this "6" is because somebody suggested to use the
default "6" instead of "9" in your original and the suggestion
was because "9" tends to be too expensive.  

But if we do not have a good, specific, reason to use "6" (as
opposed to, say, "5" or "7") and have "6" here only because we
happen to know "6" is the current gzip default, then probably we
are better off just letting gzip decide what compression level
to use without specifying it ourselves?

Please feel free to change the code. Or if you want me to send another
patch with the changes suggested i can do the same. Let me know.

yes that is correct. I  changed it because it was suggested.

Wouldn't it be better to put $hash somewhere in the name?

And please remember that $project can contain slashes, so it should be processed
(only basename of $project, perhaps).

Isn't there some other way to tell the webbroser how to name the file?
I thought there is some HTML header to explicitly give one file name.

Something like in line 1923?
  $cgi->header(-type => "$type", '-content-disposition' => "inline; filename=\"$save_as\"");
