[PATCH] Improved "git add"

This fixes everybodys favourite complaint about "git add", namely that it
doesn't take directories.

We use "git-ls-files --others" to generate an arbitrary list of filenames,
and thus also automatically honor ignore-files while we're at it.

Side note: there's a lot of room for improvement here. In particular, if
we have a long list of filenames (importing a big archive), this will just
do a big stupid for-loop and add them one at a time. Maybe it should use

generate-list | xargs -0 git-update-idex --add --

instead.

Also, I think we should have a default ignore list if we don't find a
.git/info/exclude file. Ignoring "*.o" and ".*" by default would probably
be the right thing to do.

However, nothing else really needs it, and it's quite expensive for

So, exactly like the commit buffer save thing, add a global flag to

Before:

particular object list has shrunk from 26,718 (104 MB) to 18,509 (72 MB).

Calculating the total object difference between two git revisions is still

[PATCH] Re-organize "git-rev-list --objects" logic

The logic to calculate the full object list used to be very inter-twined
with the logic that looked up the commits.

For no good reason - it's actually a lot simpler to just do that logic
as a separate pass.

This improves performance a bit, and uses slightly less memory in my
tests, but more importantly it makes the code simpler to work with and
follow what it does.

The performance win is less than I had hoped for, but I get:

Before:

[torvalds@g5 linux]$ /usr/bin/time git-rev-list --objects v2.6.12..HEAD | wc -l

ie it improved by 2 seconds, and took a 5000+ fewer pages (hey, that's
20MB out of 174MB to go). And got the same number of objects (in theory,
the more expensive one might find some more shared objects to avoid. In
practice it obviously doesn't).

I know how to make it use _lots_ less memory, which will probably speed it
up. But that's for another time, and I'd prefer to see this go in first.

Linus Torvalds [Thu, 15 Sep 2005 21:43:17 +0000 (14:43 -0700)]
[PATCH] Avoid wasting memory in git-rev-list

As pointed out on the list, git-rev-list can use a lot of memory.

One low-hanging fruit is to free the commit buffer for commits that we
parse. By default, parse_commit() will save away the buffer, since a lot
of cases do want it, and re-reading it continually would be unnecessary.
However, in many cases the buffer isn't actually necessary and saving it
just wastes memory.

We could just free the buffer ourselves, but especially in git-rev-list,
we actually end up using the helper functions that automatically add
parent commits to the commit lists, so we don't actually control the
commit parsing directly.

Instead, just make this behaviour of "parse_commit()" a global flag.
Maybe this is a bit tasteless, but it's very simple, and it makes a
noticable difference in memory usage.

Before the change:

[torvalds@g5 linux]$ /usr/bin/time git-rev-list v2.6.12..HEAD > /dev/null

0inputs+0outputs (0major+2433minor)pagefaults 0swaps

note how the minor faults have decreased from 3714 pages to 2433 pages.
That's all due to the fewer anonymous pages allocated to hold the comment
buffers and their metadata.

[PATCH] There are several undocumented dependencies

There are several undocumented dependencies in the .spec and in the
INSTALL files. The following is from Fedora, perhaps other RPM
distributions call the packages differently.

Also, the manpages aren't always installed gzipped.

Updates to git-core.spec.in file:
 - Some git scripts use Perl
 - gitk needs wish, which is part of TCL/Tk.
 - curl is used all over
 - Need the ssh program from openssh-clients

Updates to INSTALL:
 - Mention wish
 - Mention ssh

Improve "git grep" flags handling

This allows any arbitrary flags to "grep", and knows about the few
special grep flags that take an argument too.

It also allows some flags for git-ls-files, although their usefulness
is questionable.

With this, something line

git grep -w -1 pattern

works, without the script enumerating every possible flag.

[jc: this is the version Linus sent out after I showed him a
 barf-o-meter test version that avoids shell arrays.  He must
 have typed this version blindly, since he said:

    I'm not barfing, but that's probably because my brain just shut

Multi-backend merge driver.

The new command 'git merge' takes the current head and one or more
remote heads, with the commit log message for the automated case.

If the heads being merged are simple fast-forwards, it acts the
same way as the current 'git resolve'.  Otherwise, it tries
different merge strategies and takes the result from the one that
succeeded auto-merging, if there is any.

If no merge strategy succeeds auto-merging, their results are
evaluated for number of paths needed for hand resolving, and the
one with the least number of such paths is left in the working
tree.  The user is asked to resolve them by hand and make a
commit manually.

The calling convention from the 'git merge' driver to merge
strategy programs is very simple:

 - A strategy program is to be called 'git-merge-<strategy>'.

 - They take input of this form:

<common1> <common2> ... '--' <head> <remote1> <remote2>...

   That is, one or more the common ancestors, double dash, the
   current head, and one or more remote heads being merged into
   the current branch.

 - Before a strategy program is called, the working tree is
   matched to the current <head>.

 - The strategy program exits with status code 0 when it
   successfully auto-merges the given heads.  It should do
   update-cache for all the merged paths when it does so -- the
   index file will be used to record the merge result as a
   commit by the driver.

 - The strategy program exits with status code 1 when it leaves
   conflicts behind.  It should do update-cache for all the
   merged paths that it successfully auto-merged, and leave the
   cache entry in the index file as the same as <head> for paths
   it could not auto-merge, and leave its best-effort result
   with conflict markers in the working tree when it does so.

 - The strategy program exists with status code other than 0 or
   1 if it does not handle the given merge at all.

As examples, this commit comes with merge strategies based on
'git resolve' and 'git octopus'.
