Merge branch 'nd/no-more-fnmatch'

2014-03-14T21:25:31+00:00

We started using wildmatch() in place of fnmatch(3); complete the
process and stop using fnmatch(3).

* nd/no-more-fnmatch:
  actually remove compat fnmatch source code
  stop using fnmatch (either native or compat)
  Revert "test-wildmatch: add "perf" command to compare wildmatch and fnmatch"
  use wildmatch() directly without fnmatch() wrapper

Merge branch 'jk/pack-bitmap'

2014-02-27T22:01:48+00:00

Borrow the bitmap index into packfiles from JGit to speed up
enumeration of objects involved in a commit range without having to
fully traverse the history.

* jk/pack-bitmap: (26 commits)
  ewah: unconditionally ntohll ewah data
  ewah: support platforms that require aligned reads
  read-cache: use get_be32 instead of hand-rolled ntoh_l
  block-sha1: factor out get_be and put_be wrappers
  do not discard revindex when re-preparing packfiles
  pack-bitmap: implement optional name_hash cache
  t/perf: add tests for pack bitmaps
  t: add basic bitmap functionality tests
  count-objects: recognize .bitmap in garbage-checking
  repack: consider bitmaps when performing repacks
  repack: handle optional files created by pack-objects
  repack: turn exts array into array-of-struct
  repack: stop using magic number for ARRAY_SIZE(exts)
  pack-objects: implement bitmap writing
  rev-list: add bitmap mode to speed up object lists
  pack-objects: use bitmaps when packing objects
  pack-objects: split add_object_entry
  pack-bitmap: add support for bitmap indexes
  documentation: add documentation for the bitmap format
  ewah: compressed bitmap implementation
  ...

* ef/mingw-write:
  mingw: remove mingw_write
  prefer xwrite instead of write

read-cache: use get_be32 instead of hand-rolled ntoh_l

2014-01-23T22:03:48+00:00

Commit d60c49c (read-cache.c: allow unaligned mapping of the
index file, 2012-04-03) introduced helpers to access
unaligned data. However, we already have get_be32, which has
a few advantages:

  1. It's already written, so we avoid duplication.

  2. It's probably faster, since it does the endian
     conversion and the alignment fix at the same time.

  3. The get_be32 code is well-tested, having been in
     block-sha1 for a long time. By contrast, our custom
     helpers were probably almost never used, since the user
     needed to manually define a macro to enable them.

We have to add a get_be16 implementation to the existing
get_be32, but that is very simple to do.

block-sha1: factor out get_be and put_be wrappers

2014-01-23T22:03:21+00:00

The BLK_SHA1 code has optimized wrappers for doing endian
conversions on memory that may not be aligned. Let's pull
them out so that we can use them elsewhere, especially the
time-tested list of platforms that prefer each strategy.

mingw: remove mingw_write

2014-01-17T20:09:52+00:00

Since 0b6806b9 ("xread, xwrite: limit size of IO to 8MB"), this
wrapper is no longer needed, as read and write are already split
into small chunks.

mark Windows build scripts executable

2013-11-25T23:01:22+00:00

On Windows the convention is to rely on filename extensions to decide
whether a file is executable so Windows users are probably not relying
on the executable bit of these scripts, but on other platforms it can
be useful documentation.

compat: add endianness helpers

2013-11-18T18:57:42+00:00

The POSIX standard doesn't currently define a `ntohll`/`htonll`
function pair to perform network-to-host and host-to-network
swaps of 64-bit data. These 64-bit swaps are necessary for the on-disk
storage of EWAH bitmaps if they are not in native byte order.

Many thanks to Ramsay Jones  and
Torsten Bögershausen  for cygwin/mingw/msvc
portability fixes.

C: have space around && and || operators

2013-10-16T17:26:39+00:00

Correct all hits from

    git grep -e '\(&&\|||\)[^ ]' -e '[^	 ]\(&&\|||\)' -- '*.c'

i.e. && or || operators that are followed by anything but a SP,
or that follow something other than a SP or a HT, so that these
operators have a SP around it when necessary.

We usually refrain from making this kind of a tree-wide change in
order to avoid unnecessary conflicts with other "real work" patches,
but in this case, the end result does not have a potentially
cumbersome tree-wide impact, while this is a tree-wide cleanup.

Fixes to compat/regex/regcomp.c and xdiff/xemit.c are to replace a
HT immediately after && with a SP.

This is based on Felipe's patch to bultin/symbolic-ref.c; I did all
the finding out what other files in the whole tree need to be fixed
and did the fix and also the log message while reviewing that single
liner, so any screw-ups in this version are mine.
