Restore SIGCHLD to SIG_DFL where we care about waitpid().
It was reported that under one implementation of socks client
"git clone" fails with "error: waitpid failed (No child processes)",
because "git" is spawned after setting SIGCHLD to SIG_IGN.
Arguably it may be a broken setting, but we should protect
ourselves so that we can get reliable results from waitpid() for
the children we care about.
This patch resets SIGCHLD to SIG_DFL in three places:
- connect.c::git_connect() - initiators of git native
protocol transfer are covered with this.
- daemon.c::main() - obviously.
- merge-index.c::main() - obviously.
There are other programs that do fork() but do not waitpid():
http-push, imap-send. upload-pack does not either, but in the
case of that program, each of the forked halves runs exec()
another program, so this change would not have much effect
there.

Add specialized object allocator
This creates a simple specialized object allocator for basic
objects.
This avoids wasting space with malloc overhead (metadata and
extra alignment), since the specialized allocator knows the
alignment, and that objects, once allocated, are never freed.
It also allows us to track some basic statistics about object
allocations. For example, for the mozilla import, it shows
object usage as follows:
blobs: 627629 (14710 kB)
trees:
1119035 (34969 kB)
commits: 196423 (8440 kB)
tags: 1336 (46 kB)
and the simpler allocator shaves off about 2.5% off the memory
footprint off a "git-rev-list --all --objects", and is a bit
faster too.
[ Side note: this concludes the series of "save memory in object storage".
The thing is, there simply isn't much more to be saved on the objects.
Doing "git-rev-list --all --objects" on the mozilla archive has a final
total RSS of 131498 pages for me: that's about 513MB. Of that, the
object overhead is now just 56MB, the rest is going somewhere else (put
another way: the fact that this patch shaves off 2.5% of the total
memory overhead, considering that objects are now not much more than 10%
of the total shows how big the wasted space really was: this makes
object allocations much more memory- and time-efficient).
I haven't looked at where the rest is, but I suspect the bulk of it is
just the pack-file loading. It may be that we should pack the tree
objects separately from the blob objects: for git-rev-list --objects, we
don't actually ever need to even look at the blobs, but since trees and
blobs are interspersed in the pack-file, we end up not being dense in
the tree accesses, so we end up looking at more pages than we strictly
need to.
So with a 535MB pack-file, it's entirely possible - even likely - that
most of the remaining RSS is just the mmap of the pack-file itself. We
don't need to map in _all_ of it, but we do end up mapping a fair
amount. ]

Remove "refs" field from "struct object"
This shrinks "struct object" to the absolutely minimal size possible.
It now contains /only/ the object flags and the SHA1 hash name of the

The "refs" field, which is really needed only for fsck, is maintained in
a separate hashed lookup-table, allowing all normal users to totally
ignore it.
This helps memory usage, although not as much as I hoped: it looks like
the allocation overhead of malloc (and the alignment constraints in
particular) means that while the structure size shrinks, the actual
allocation overhead mostly does not.
[ That said: memory usage is actually down, but not as much as it should
be: I suspect just one of the object types actually ended up shrinking
its effective allocation size.
To get to the next level, we probably need specialized allocators that

Some more memory leak avoidance
This is really the dregs of my effort to not waste memory in git-rev-list,
and makes barely one percent of a difference in the memory footprint, but
hey, it's also a pretty small patch.
It discards the parent lists and the commit buffer after the commit has
been shown by git-rev-list (and "git log" - which already did the commit
buffer part), and frees the commit list entry that was used by the
revision walker.
The big win would be to get rid of the "refs" pointer in the object
structure (another 5%), because it's only used by fsck. That would require
some pretty major surgery to fsck, though, so I'm timid and did the less
interesting but much easier part instead.
This (percentually) makes a bigger difference to "git log" and friends,
since those are walking _just_ commits, and thus the list entries tend to
be a bigger percentage of the memory use. But the "list all objects" case
does improve too.

Shrink "struct object" a bit
This shrinks "struct object" by a small amount, by getting rid of the
"struct type *" pointer and replacing it with a 3-bit bitfield instead.
In addition, we merge the bitfields and the "flags" field, which
incidentally should also remove a useless 4-byte padding from the object
when in 64-bit mode.
Now, our "struct object" is still too damn large, but it's now less
obviously bloated, and of the remaining fields, only the "util" (which is
not used by most things) is clearly something that should be eventually
discarded.
This shrinks the "git-rev-list --all" memory use by about 2.5% on the
kernel archive (and, perhaps more importantly, on the larger mozilla
archive). That may not sound like much, but I suspect it's more on a
64-bit platform.
There are other remaining inefficiencies (the parent lists, for example,
probably have horrible malloc overhead), but this was pretty obvious.
Most of the patch is just changing the comparison of the "type" pointer
from one of the constant string pointers to the appropriate new TYPE_xxx
small integer constant.

gitweb.cgi history not shown

- add a "rev.simplify_history" flag which defaults to on
- it turns it off for "git whatchanged" (which thus now has real

- it adds a command line flag ("--full-history") to turn it off for
others (ie you can make "git log" and "gitk" etc get the semantics if
you want to.
Now, just as an example of _why_ you really really really want to simplify
history by default, apply this patch, install it, and try these two
command lines:
gitk --full-history -- git.c
gitk -- git.c
and compare the output.
So with this, you can also now do
git whatchanged -p -- gitweb.cgi
git log -p --full-history -- gitweb.cgi
and it will show the old history of gitweb.cgi, even though it's not
relevant to the _current_ state of the name "gitweb.cgi"
NOTE NOTE NOTE! It will still actually simplify away merges that didn't
change anything at all into either child. That creates these bogus strange
discontinuities if you look at it with "gitk" (look at the --full-history
gitk output for git.c, and you'll see a few strange cases).
So the whole "--parent" thing ends up somewhat bogus with --full-history
because of this, but I'm not sure it's worth even worrying about. I don't
think you'd ever want to really use "--full-history" with the graphical
representation, I just give it as an example exactly to show _why_ doing

Pass the -d flag to git repack by default. That's the
main reason we will want automatic pack generation, to
save space and improve disk cache performance. I won't
add -a by default since it can generate extremely large
packs that make RAM-starved systems unhappy.
We no longer generate the .git/svn/$GIT_SVN_ID/info/uuid
file, either. It was never read in the first place.
Check for and create .rev_db if we need to during fetch (in case
somebody manually blew away their .rev_db and wanted to start
over. Mainly makes debugging easier).
Croak with $? instead of $! if there's an error closing pipes
Quiet down some of the chatter, too.

git-svn: make the $GIT_DIR/svn/*/revs directory obsolete
This is a very intrusive change, so I've beefed up the tests
significantly. Added 'full-test' a target to the Makefile,
to test different possible configurations. This is intended
for maintainers only. Users should only be concerned with
'test' succeeding.
We now have a very simple custom database format for handling
mapping of svn revisions => git commits. Of course, we're
not really using it yet, either.
Also disabled automatic branch-finding on new trees for now.
It's too easily broken. revisions_eq() function should be
helpful for branch detection.
Also removed an extra assertion in fetch_cmd() that wasn't
correctly done. This bug was found by full-test.

git-svn: add support for Perl SVN::* libraries
This means we no longer have to deal with having bloated SVN
working copies around and we get a nice performance increase as
well because we don't have to exec the SVN binary and start a
new server connection each time.
Of course we have to manually manage memory with SVN::Pool
whenever we can, and hack around cases where SVN just eats
memory despite pools (I blame Perl, too). I would like to
keep memory usage as stable as possible during long fetch/commit
processes since I still use computers with only 256-512M RAM.
commit should always be faster with the SVN library code. The
SVN::Delta interface is leaky (or I'm not using it with pools
correctly), so I'm forking on every commit, but that doesn't
seem to hurt performance too much (at least on normal Unix/Linux
systems where fork() is pretty cheap).
fetch should be faster in most common cases, but probably not all.
fetches will be faster where client/server delta generation is
the bottleneck and not bandwidth. Of course, full-files are
generated server-side via deltas, too. Full files are always
transferred when they're updated, just like git-svnimport and
unlike command-line svn. I'm also hacking around memory leaks
(see comments) here by using some more forks.
I've tested fetch with http://, https://, file://, and svn://
repositories, so we should be reasonably covered in terms of
error handling for fetching.
Of course, we'll keep plain command-line svn compatibility as a
fallback for people running SVN 1.1 (I'm looking into library
support for 1.1.x SVN, too). If you want to force command-line
SVN usage, set GIT_SVN_NO_LIB=1 in your environment.
We also require two simultaneous connections (just like
git-svnimport), but this shouldn't be a problem for most
servers.
Less important commands:
show-ignore is slower because it requires repository
access, but -r/--revision <num> can be specified.
graft-branches may use more memory, but it's a
short-term process and is funky-filename-safe.

git-svn: add some functionality to better support branches in svn
New commands:
graft-branches - The most interesting command of the bunch. It
detects branches in SVN via various techniques (currently
regexes and file copies). It can be later extended to handle
svk and other properties people may use to track merges in svk.
Basically, merge tracking is not standardized at all in the SVN
world, and git grafts are perfect for dealing with this
situation.
Existing branch support (via tree matches) is only handled at
fetch time.
The following tow were originally implemented as shell scripts
several months ago, but I just decided to streamline things a
bit and added them to the main script.
multi-init - supports git-svnimport-like command-line syntax for
importing repositories that are layed out as recommended by the
SVN folks. This is a bit more tolerant than the git-svnimport
command-line syntax and doesn't require the user to figure out
where the repository URL ends and where the repository path
begins.
multi-fetch - runs fetch on all known SVN branches we're
tracking. This will NOT discover new branches (unlike
git-svnimport), so multi-init will need to be re-run (it's
idempotent).
Consider these three to be auxilliary commands (like
show-ignore, and rebuild) so their behavior won't receive as
much testing or scrutiny as the core commands (fetch and
commit).
