Jeff King [Tue, 18 Feb 2014 22:58:52 +0000 (00:58 +0200)] 
config: disallow relative include paths from blobs

When we see a relative config include like:

  [include]
  path = foo

we make it relative to the containing directory of the file
that contains the snippet. This makes no sense for config
read from a blob, as it is not on the filesystem.  Something
like "HEAD:some/path" could have a relative path within the
tree, but:

  1. It would not be part of include.path, which explicitly
     refers to the filesystem.

  2. It would need different parsing rules anyway to
     determine that it is a tree path.

The current code just uses the "name" field, which is wrong.
Let's split that into "name" and "path" fields, use the
latter for relative includes, and fill in only the former
for blobs.

repack.c: rename and unlink pack file if it exists

When a repo was fully repacked, and is repacked again, we may run
into the situation that "new" packfiles have the same name as
already existing ones (traditionally packfiles have been named after
the list of names of objects in them, so repacking all the objects
in a single pack would have produced a packfile with the same name).

The logic is to rename the existing ones into filename like
"old-XXX", create the new ones and then remove the "old-" ones.
When something went wrong in the middle, this sequence is rolled
back by renaming the "old-" files back.

The renaming into "old-" did not work as intended, because
file_exists() was done on "XXX", not "pack-XXX".  Also when rolling
back the change, the code tried to rename "old-pack-XXX" but the
saved ones are named "old-XXX", so this couldn't have worked.

a feature of test-chmtime, but fortunately this fix is even
easier.

The test does not care about the timestamp of the .keep file it

10 years agot7501: fix "empty commit" test with NO_PERL
Jeff King [Thu, 23 Jan 2014 19:54:57 +0000 (14:54 -0500)] 
t7501: fix "empty commit" test with NO_PERL

t7501.9 tries to check that "git commit" will fail when the
index is unchanged. It relies on previous tests not to have
modified the index. When it was originally written, this was
always the case. However, commit c65dc35 (t7501: test the
right kind of breakage, 2012-03-30) changed earlier tests (4
and 5) to leave a modification in the index.

We never noticed, however, because t7501.7, between the two,
clears the index state as a side effect. However, that test
depends on the PERL prerequisite, and so it does not always
run. Therefore if NO_PERL is set, we do not run the
intervening test, the index is left unclean, and t7501.9
fails.

We could fix this by moving t7501.9 up in the script.
However, this patch instead leaves it in place and adds a
"git reset" before the commit. This makes the test more
explicit about its preconditions, and will future-proof it
against any other changes in the test state.

10 years agorepack: propagate pack-objects options as strings
Jeff King [Thu, 23 Jan 2014 01:30:13 +0000 (20:30 -0500)] 
repack: propagate pack-objects options as strings

In the original shell version of git-repack, any options
destined for pack-objects were left as strings, and passed
as a whole. Since the C rewrite in commit a1bbc6c (repack:
rewrite the shell script in C, 2013-09-15), we now parse
these values to integers internally, then reformat the
integers when passing the option to pack-objects.

This has the advantage that we catch format errors earlier
(i.e., when repack is invoked, rather than when pack-objects
is invoked).

It has three disadvantages, though:

  1. Our internal data types may not be the right size. In
     the case of "--window-memory" and "--max-pack-size",
     these are "unsigned long" in pack-objects, but we can
     only represent a regular "int".

  2. Our parsing routines might not be the same as those of
     pack-objects. For the two options above, pack-objects
     understands "100m" to mean "100 megabytes", but repack
     does not.

  3. We have to keep a sentinel value to know whether it is
     worth passing the option along. In the case of
     "--window-memory", we currently do not pass it if the
     value is "0". But that is a meaningful value to
     pack-objects, where it overrides any configured value.

We can fix all of these by simply passing the strings from
the user along to pack-objects verbatim. This does not
actually fix anything for "--depth" or "--window", but these
are converted, too, for consistency.

Makefile: Fix compilation of Windows resource file

If the git version number consists of less than three period
separated numbers, then the Windows resource file compilation
issues a syntax error:

  $ touch git.rc
  $ make V=1 git.res

  make: *** [git.res] Error 1
  $

Note that -DPATCH=rc0.

The values passed via -DMAJOR=, -DMINOR=, and -DPATCH= are used in
FILEVERSION and PRODUCTVERSION statements, which expect up to four numeric
values. These version numbers are intended for machine consumption. They
are typically inspected by installers to decide whether a file to be
installed is newer than one that exists on the system, but are not used
for much else.

We can be pretty certain that there are no tools that look at these
version numbers, not even the installer of Git for Windows does.
Therefore, to fix the syntax error, fill in only the first two numbers,
which we are guaranteed to find in Git version numbers.
