This library provides thread-unsafe fgets()- and fread()-like
functions where the caller does not have to supply a buffer. It
maintains a couple of static buffers and provides an API to use
them.

Intern strings so they can be compared by address and stored without
wasting space.
This library uses the macros in the obj_pool.h and trp.h to create a
memory pool for strings and expose an API for handling them.

Provide macros to generate a type-specific treap implementation and
various functions to operate on it. It uses obj_pool.h to store memory
nodes in a treap. Previously committed nodes are never removed from
the pool; after any *_commit operation, it is assumed (correctly, in
the case of svn-fast-export) that someone else must care about them.
Treaps provide a memory-efficient binary search tree structure.
Insertion/deletion/search are about as about as fast in the average
case as red-black trees and the chances of worst-case behavior are
vanishingly small, thanks to (pseudo-)randomness. The bad worst-case
behavior is a small price to pay, given that treaps are much simpler
to implement.

Add a memory pool library implemented using C macros. The
obj_pool_gen() macro creates a type-specific memory pool.
The memory pool library is distinguished from the existing specialized
allocators in alloc.c by using a contiguous block for all allocations.
This means that on one hand, long-lived pointers have to be written as
offsets, since the base address changes as the pool grows, but on the
other hand, the entire pool can be easily written to the file system.
This could allow the memory pool to persist between runs of an
application.
For the svn importer, such a facility is useful because each svn
revision can copy trees and files from any previous revision. The
relevant information for all revisions has to persist somehow to
support incremental runs.

fast-import: export correctly marks larger than 2^20-1
t/lib-git-svn.sh: use $PERL_PATH for perl, not perl from $PATH
diff: strip extra "/" when stripping prefix
|
|
dump_marks_helper() has a bug when dumping marks larger than 2^20-1,
i.e., when the sparse array has more than two levels. The bug was
that the 'base' counter was being shifted by 20 bits at level 3, and
then again by 10 bits at level 2, rather than a total shift of 20 bits
in this argument to the recursive call:
(base + k) << m->shift
There are two ways to fix this correctly, the elegant:
(base + k) << 10
and the one I chose due to edit distance:
base + (k << m->shift)

Change the git-svn tests to use $PERL_PATH, not the "perl" in $PATH.
Using perl in $PATH was added by Sam Vilain in v1.6.6-rc0~95^2~3,
Philippe Bruhat introduced $PERL_PATH to the test suite in
v1.6.6-rc0~9^2, but the lib-git-svn.sh tests weren't updated to use
the new convention.
This resulted in the git-svn tests always being skipped on my
system. My /usr/bin/perl has access to SVN::Core and SVN::Repos, but
the perl in my $PATH does not.

There are two ways a user might want to use "diff --relative":
1. For a file in a directory, like "subdir/file", the user
can use "--relative=subdir/" to strip the directory.
2. To strip part of a filename, like "foo-10", they can
use "--relative=foo-".
We currently handle both of those situations. However, if the user passes
"--relative=subdir" (without the trailing slash), we produce inconsistent
results. For the unified diff format, we collapse the double-slash of
"a//file" correctly into "a/file". But for other formats (raw, stat,
name-status), we end up with "/file".
We can do what the user means here and strip the extra "/" (and only a
slash). We are not hurting any existing users of (2) above with this
behavior change because the existing output for this case was nonsensical.

The test would not fail if the filtering failed to do anything, since
in
test -z "$(git diff HEAD directorymoved:newsubdir)"'
'directorymoved:newsubdir' is not valid, so git-diff fails without
printing anything on stdout. But then the exit status of git-diff is
lost, whereas test -z "" succeeds.
Use 'git diff --exit-code' instead, which does the right thing and has
the added bonus of showing the differences if there are any.

The dcommit command fails if an otherwise unmodified file has
been touched in the working directory:
Cannot dcommit with a dirty index. Commit your changes
first, or stash them with `git stash'.
This happens because "git diff-index" reports a difference
between the index and the filesystem:
:100644 100644 d00491...... 000000...... M file
The fix is to run "git update-index --refresh" before
"git diff-index" as is done in git-rebase and
git-rebase--interactive before "git diff-files".
This changes dcommit to display a list of modified files before
exiting.
Also add a similar test case for "git svn rebase".

Running the tests with --quiet under a TAP harness will always fail,
since a TAP harness always needs actual test output to go along with
the plan that's being emitted.
Change the test-lib.sh to ignore the --quiet option under
HARNESS_ACTIVE to work around this. Then users that have --quiet in
their GIT_TEST_OPTS can run tests under prove(1) without everything
breaking.

When performing a non-interactive rebase, sometimes
"git rebase --continue" will fail if an unmodified file is
touched in the working directory:
You must edit all merge conflicts and then
mark them as resolved using git add
This is caused by "git diff-files" reporting a difference
between the index and the filesystem:
:100644 100644 d00491...... 000000...... M file
The fix is to run "git update-index --refresh" before
"git diff-files" as is done in git-rebase--interactive.

One test case checked the stdout and stderr of 'git add' by constructing a
single 'expect' file that contained both streams. But when the command
runs, the order of stdout and stderr output is unpredictable because it
depends on how the streams are buffered. At least on Windows, the buffering
is different from what the test case expected. Hence, check the two output
texts separately.

On systems with an echo which defaults to the XSI-conformant behavior
(Solaris, or others using Ksh), echo will interpret certain backslashed
characters as control sequences. This can cause a problem for interactive
rebase when it is used to rebase commits whose commit "subject" (the first
line) contains any of these backslashed sequences. In this case, echo will
substitute the control sequence for the backslashed characters and either
the rebased commit message will differ from the original, or the rebase
process will fail. Neither is desirable.
So work around this issue by replacing the echo statements used to print
out portions of the commit message, with printf.
Also, add a test to test for this breakage.

These two tests weren't about how "git reflog show <branch>" exits when
there is no reflog, but were about "checkout" and "branch" create or not
create reflog when creating a new <branch>. Update the tests to check
what we are interested in, using "git rev-parse --verify".
Also lose tests based on "test -f .git/logs/refs/heads/<branch>" from
nearby, to avoid exposing this particular implementation detail
unnecessarily.

The correct advice should have been taken from c289c31 (t/t7006: ignore
return status of shell's unset builtin, 2010-06-02). A real-life issue
we experienced was with "unset", not with "export" (exporting an
unset variable may have similar portability issues, though).

The '!()' notation is interpreted as a pattern-list on Ksh. The Ksh man
page describe it as follows:
!(pattern-list)
Matches anything except one of the given patterns.
Ksh performs a file glob using the pattern-list and then tries to execute
the first file in the list. If a space is added between the '!' and the
open parens, then Ksh will not interpret it as a pattern list, but in this
case, it is preferred to use test_must_fail, so lets do so.

These two lines use the negation '!' operator to negate the result of a
simple command. Since these commands do not contain any pipes or other
complexities, the test_must_fail function can be used and is preferred
since it will additionally detect termination due to a signal.
This was noticed because the second use of '!' does not include a space
between the '!' and the opening parens. Ksh interprets this as follows:
!(pattern-list)
Matches anything except one of the given patterns.

Some have found the wording of the description to be somewhat ambiguous
with respect to when it is desirable to use test_must_fail instead of
"! <git-command>". Tweak the wording somewhat to hopefully clarify that
it is _because_ test_must_fail can detect segmentation fault that it is
desirable to use it instead of "! <git-command>".
