Move 'builtin-*' into a 'builtin/' subdirectory

2010-02-22T22:29:41+00:00

This shrinks the top-level directory a bit, and makes it much more
pleasant to use auto-completion on the thing. Instead of

	[torvalds@nehalem git]$ em buil
	Display all 180 possibilities? (y or n)
	[torvalds@nehalem git]$ em builtin-sh
	builtin-shortlog.c     builtin-show-branch.c  builtin-show-ref.c
	builtin-shortlog.o     builtin-show-branch.o  builtin-show-ref.o
	[torvalds@nehalem git]$ em builtin-shor
	builtin-shortlog.c  builtin-shortlog.o
	[torvalds@nehalem git]$ em builtin-shortlog.c

you get

	[torvalds@nehalem git]$ em buil		[type]
	builtin/   builtin.h
	[torvalds@nehalem git]$ em builtin		[auto-completes to]
	[torvalds@nehalem git]$ em builtin/sh	[type]
	shortlog.c     shortlog.o     show-branch.c  show-branch.o  show-ref.c     show-ref.o
	[torvalds@nehalem git]$ em builtin/sho		[auto-completes to]
	[torvalds@nehalem git]$ em builtin/shor	[type]
	shortlog.c  shortlog.o
	[torvalds@nehalem git]$ em builtin/shortlog.c

which doesn't seem all that different, but not having that annoying
break in "Display all 180 possibilities?" is quite a relief.

NOTE! If you do this in a clean tree (no object files etc), or using an
editor that has auto-completion rules that ignores '*.o' files, you
won't see that annoying 'Display all 180 possibilities?' message - it
will just show the choices instead.  I think bash has some cut-off
around 100 choices or something.

So the reason I see this is that I'm using an odd editory, and thus
don't have the rules to cut down on auto-completion.  But you can
simulate that by using 'ls' instead, or something similar.

Revert "pack-objects: fix pack generation when using pack_size_limit"

2010-02-08T18:56:21+00:00

This reverts most of commit a2430dde8ceaaaabf05937438249397b883ca77a.

That commit made the situation better for repositories with relatively
small number of objects.  However with many objects and a small pack size
limit, the time required to complete the repack tends towards O(n^2),
or even much worse with long delta chains.

make --max-pack-size argument to 'git pack-object' count in bytes

2010-02-04T04:39:56+00:00

The value passed to --max-pack-size used to count in MiB which was
inconsistent with the corresponding configuration variable as well as
other command arguments which are defined to count in bytes with an
optional unit suffix.  This brings --max-pack-size in line with the
rest of Git.

Also, in order not to cause havoc with people used to the previous
megabyte scale, and because this is a sane thing to do anyway, a
minimum size of 1 MiB is enforced to avoid an explosion of pack files.

Adjust and extend test suite accordingly.

pack-objects: fix pack generation when using pack_size_limit

2010-02-04T04:39:24+00:00

Current handling of pack_size_limit is quite suboptimal.  Let's consider
a list of objects to pack which contain alternatively big and small
objects (which pretty matches reality when big blobs are interlaced
with tree objects).  Currently, the code simply close the pack and opens
a new one when the next object in line breaks the size limit.

The current code may degenerate into:

  - small tree object => store into pack #1
  - big blob object busting the pack size limit => store into pack #2
  - small blob but pack #2 is over the limit already => pack #3
  - big blob busting the size limit => pack #4
  - small tree but pack #4 is over the limit => pack #5
  - big blob => pack #6
  - small tree => pack #7
  - ... and so on.

The reality is that the content of packs 1, 3, 5 and 7 could well be
stored more efficiently (and delta compressed) together in pack #1 if
the big blobs were not forcing an immediate transition to a new pack.

Incidentally this can be fixed pretty easily by simply skipping over
those objects that are too big to fit in the current pack while trying
the whole list of unwritten objects, and then that list considered from
the beginning again when a new pack is opened.  This creates much fewer
smallish pack files and help making more predictable test cases for the
test suite.

This change made one of the self sanity checks useless so it is removed
as well. That check was rather redundant already anyway.

Make NO_PTHREADS the sole thread configuration variable

2010-01-31T19:50:50+00:00

When the first piece of threaded code was introduced in commit 8ecce684, it
came with its own THREADED_DELTA_SEARCH Makefile option. Since this time,
more threaded code has come into the codebase and a NO_PTHREADS option has
also been added. Get rid of the original option as the newer, more generic
option covers everything we need.

make "index-pack" a built-in

2010-01-22T18:10:27+00:00

This required some fairly trivial packfile function 'const' cleanup,
since the builtin commands get a const char *argv[] array.

git_attr(): fix function signature

2010-01-17T04:39:59+00:00

The function took (name, namelen) as its arguments, but all the public
callers wanted to pass a full string.

Demote the counted-string interface to an internal API status, and allow
public callers to just pass the string to the function.

MSVC: Windows-native implementation for subset of Pthreads API

2010-01-17T02:16:06+00:00

This patch implements native to Windows subset of pthreads API used by Git.
It allows to remove Pthreads for Win32 dependency for MSVC, msysgit and
Cygwin.

[J6t: If the MinGW build was built as part of the msysgit build
environment, then threading was already enabled because the
pthreads-win32 package is available in msysgit. With this patch, we can now
enable threaded code unconditionally.]
