18 years agoSome more memory leak avoidance

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.

Move "void *util" from "struct object" into "struct commit"

Every single user actually wanted this only for commit objects, and we
have no reason to waste space on it for other object types. So just move
the structure member from the low-level "struct object" into the "struct
commit".

This leaves the commit object the same size, and removes one unnecessary
pointer from all other object allocations.

This shrinks memory usage (still at a fairly hefty half-gig, admittedly)
of "git-rev-list --all --objects" on the mozilla repo by another 5% in my

Linus Torvalds [Wed, 14 Jun 2006 23:45:13 +0000 (16:45 -0700)]
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

This does:

 - add a "rev.simplify_history" flag which defaults to on
 - it turns it off for "git whatchanged" (which thus now has real
   semantics outside of "git log")
 - 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
so would be insane.

I think this is trivial enough and useful enough to be worth merging into

Eric Wong [Mon, 12 Jun 2006 22:23:48 +0000 (15:23 -0700)]
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.

18 years agogit-svn: add some functionality to better support branches in svn
Eric Wong [Mon, 12 Jun 2006 22:53:13 +0000 (15:53 -0700)]
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).

Linus Torvalds [Mon, 5 Jun 2006 19:03:31 +0000 (12:03 -0700)]
pack-objects: improve path grouping heuristics.

This trivial patch not only simplifies the name hashing, it actually
improves packing for both git and the kernel.

The git archive pack shrinks from 6824090->6622627 bytes (a 3%
improvement), and the kernel pack shrinks from 108756213 to 108219021 (a
mere 0.5% improvement, but still, it's an improvement from making the
hashing much simpler!)

We just create a 32-bit hash, where we "age" previous characters by two
bits, so the last characters in a filename count most. So when we then
compare the hashes in the sort routine, filenames that end the same way
sort the same way.

It takes the subdirectory into account (unless the filename is > 16
characters), but files with the same name within the same subdirectory
will obviously sort closer than files in different subdirectories.

And, incidentally (which is why I tried the hash change in the first
place, of course) builtin-rev-list.c will sort fairly close to rev-list.c.

And no, it's not a "good hash" in the sense of being secure or unique, but
that's not what we're looking for. The whole "hash" thing is misnamed
here. It's not so much a hash as a "sorting number".
