Change the tests that skipped due to unavailable SYMLINKS support to
use the three-arg prereq form of test_expect_success.
This is like the "tests: implicitly skip SYMLINKS tests using
<prereq>" change, but I needed to create an additional test for some
setup code. It's in a separate change as suggested by Jonathan Nieder
for ease of reviewing.

Probably belongs in a separate patch. More importantly, it is missing
&&-chaining (not a regression, but it is best to set a good example).

Change the smoke testing portion of t/Makefile not to include
GIT-BUILD-OPTIONS. It's a shellscript, not a Makefile snippet, so it
had the nasty side-effect of sneaking e.g. SHELL_PATH = '/bin/sh'
(with quotes) everywhere.
Just add our own PERL_PATH variable as a workaround. The t/Makefile
already has e.g. an equivalent SHELL_PATH and TAR option which
duplicate the definitions in GIT-BUILD-OPTIONS.

Add the capability to send smoke reports from the Git test suite.
Currently we only notice bugs in the test suite when it's run
manually. Bugs in Git that only occur on obscure platforms or setups
that the core developers aren't using can thus go unnoticed.
This series aims to change that. With it, anyone that's interested in
avoiding bitrot in Git can volunteer to run a smoke tester. A smoke
tester periodically compiles the latest version of Git, runs the test
suite, and submits a report to a central server indicating how the
test run went.
A smoke tester might run something like this in cron:
#!/bin/sh
cd ~/g/git
git fetch
for branch in maint master next pu; do
git checkout origin/$i &&
make clean all &&
cd t &&
make smoke_report
done
The smoker might want to compile git with non-default flags, include
bisecting functionality or run the tests under valgrind. Doing that is
outside the scope of this patch, this just adds a report submission
mechanism. But including a canonical smoke runner is something we'll
want to include eventually.
What this does now is add smoke and smoke_report targets to t/Makefile
(this example only uses a few tests for demonstration):
$ make clean smoke
rm -f -r 'trash directory'.* test-results
rm -f t????/cvsroot/CVSROOT/?*
rm -f -r valgrind/bin
rm -f .prove
perl ./harness --git-version="1.7.2.1.173.gc9b40" \

The support for multiple test prerequisites added by me in "test-lib:
Add support for multiple test prerequisites" was broken.
The for iterated over each prerequisite and returned true/false within
a case statement, but since it missed a return statement only the last
prerequisite in the list of prerequisites was ever considered, the
rest were ignored.
Fix that by changing the test_have_prereq code to something less
clever that keeps a count of the total prereqs and the ones we have
and compares the count at the end.
This comes with the added advantage that it's easy to list the missing
prerequisites in the test output, implement that while I'm at it.

Some tests depend on not being able to write to files after chmod
-w. This doesn't work when running the tests as root.
Change test-lib.sh to test if this works, and if so it sets a new

when run under root.
There was already a test for this in t3600-rm.sh, added by Junio C
Hamano in 2283645 in 2006. That check now uses the new SANITY
prerequisite.

Change the test output to print needed prerequisites as part of the
TAP. This makes it easy to see at a glance why a test was
skipped. Before:
ok 7 # skip <message>
ok 9 # skip <message>
After:
ok 7 # skip <message> (prereqs: DONTHAVEIT)
ok 9 # skip <message> (prereqs: HAVEIT,DONTHAVEIT)
This'll also be useful for smoke testing output, where the developer
reading the output may not be familiar with the system where tests are

TAP harnesses don't need to read test-results/*, since they keep track
of the number of passing/failing tests internally. Skip the generation
of these files when HARNESS_ACTIVE is set.
It's now possible to run the Git test suite without writing anything
to the t/ directory at all if you use a TAP harness and the --root
switch:
cd t
sudo mount -t tmpfs none /tmp/memory -o size=300m
prove -j9 ./t[0-9]*.sh :: --root=/tmp/memory
The I/O that the ~500 test-results/* files contributed was very
minimal, but I thought this was worth mentioning.

When mergetool is run without path limiters it loops
over each entry in 'git ls-files -u'. This includes
autoresolved paths.
Teach mergetool to only merge files listed in 'rerere status'
when rerere is enabled.
There are some subtle but harmless changes in behavior.
We now call cd_to_toplevel when no paths are given.
We do this because 'rerere status' paths are always relative
to the root. This is beneficial for the non-rerere use as
well in that mergetool now runs against all unmerged files
regardless of the current directory.
This also slightly tweaks the output when run without paths
to be more readable.
The old output:
Merging the files: foo
bar
baz
The new output:
Merging:
foo

Currently git-svn assumes that two tags created from the same
revision will have the same repo url, so it uses a ref to the
tag without checking that its url matches the current url.
This causes issues when fetching an svn repo where a tag was
created, deleted, and then recreated under the following
circumstances:
- Both tags were copied from the same revision.
- Both tags had the same name.
- Both tags had different repository paths.
- [Optional] Both tags have a file with the same name but
different content.
When all four conditions are met, a checksum mismatch error
occurs because the content of two files with the same path
differs (see t/t9155--git-svn-fetch-deleted-tag.sh):
Checksum mismatch: ChangeLog 065854....
expected: ce771b....
got: 9563fd....
When only the first three conditions are met, no error occurs
but the tag in git matches the first (deleted) tag instead of
the last (most recent) tag (see
t/t9156-git-svn-fetch-deleted-tag-2.sh).
The fix is to verify that the repo url for the ref matches the
current url. If the urls do not match, then a "tail" is grown
on the tag name by appending a dash and rechecking the new ref's
repo url until either a matching repo url is found or a new tag
is created.

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.

[jn: added tests; removed file system backing for now]

Originally, if remote.<name>.tagopt was set, the --tags and option would
have no effect when given to git fetch. So if
tagopt="--no-tags"
git fetch --tags
would not actually fetch tags.
This patch changes this behavior to only follow what is written in the
config if there is no option passed by the command line.

Prior to c85c792 (pull --rebase: be cleverer with rebased upstream
branches, 2008-01-26), pull --rebase would run
git rebase $merge_head
which resulted in a call to
git format-patch ... --ignore-if-in-upstream $merge_head..$cur_branch
This resulted in patches from $merge_head..$cur_branch being applied, as
long as they did not already exist in $cur_branch..$merge_head.
Unfortunately, when upstream is rebased, $merge_head..$cur_branch also
refers to "old" commits that have already been rebased upstream, meaning
that many patches that were already fixed upstream would be reapplied.
This could result in many spurious conflicts, as well as reintroduce
patches that were intentionally dropped upstream.
So the algorithm was changed in c85c792 (pull --rebase: be cleverer with
rebased upstream branches, 2008-01-26) and d44e712 (pull: support rebased
upstream + fetch + pull --rebase, 2009-07-19). Defining $old_remote_ref to
be the most recent entry in the reflog for @{upstream} that is an ancestor
of $cur_branch, pull --rebase was changed to run
git rebase --onto $merge_head $old_remote_ref
which results in a call to
git format-patch ... --ignore-if-in-upstream $old_remote_ref..$cur_branch
The whole point of this change was to reduce the number of commits being
reapplied, by avoiding commits that upstream already has or had.
In the rebased upstream case, this change achieved that purpose. It is
worth noting, though, that since $old_remote_ref is always an ancestor of
$cur_branch (by its definition), format-patch will not know what upstream
is and thus will not be able to determine if any patches are already
upstream; they will all be reapplied.
In the non-rebased upstream case, this new form is usually the same as the
original code but in some cases $old_remote_ref can be an ancestor of
$(git merge-base $merge_head $cur_branch)
meaning that instead of avoiding reapplying commits that upstream already
has, it actually includes more such commits. Combined with the fact that
format-patch can no longer detect commits that are already upstream (since
it is no longer told what upstream is), results in lots of confusion for
users (e.g. "git is giving me lots of conflicts in stuff I didn't even
change since my last push.")
Cases where additional commits could be reapplied include forking from a
commit other than the tracking branch, or amending/rebasing after pushing.
Cases where the inability to detect upstreamed commits cause problems
include independent discovery of a fix and having your patches get
upstreamed by some alternative route (e.g. pulling your changes to a third
machine, pushing from there, and then going back to your original machine
and trying to pull --rebase).
Fix the non-rebased upstream case by ignoring $old_remote_ref whenever it
is contained in $(git merge-base $merge_head $cur_branch). This should
have no affect on the rebased upstream case.
