53b2a5ff30 Merge branch 'jk/name-pack-after-byte-representation'
Two packfiles that contain the same set of objects have
traditionally been named identically, but that made repacking a
repository that is already fully packed without any cruft with a
different packing parameter cumbersome. Update the convention to
name the packfile after the bytestream representation of the data,
not after the set of objects in it.

65ea9c3c3d cat-file: provide %(deltabase) batch format
It can be useful for debugging or analysis to see which
objects are stored as delta bases on top of others. This
information is available by running `git verify-pack`, but
that is extremely expensive (and is harder than necessary to
parse).

Instead, let's make it available as a cat-file query format,
which makes it fast and simple to get the bases for a subset
of the objects.

5e1361ccdb log: properly handle decorations with chained tags
git log did not correctly handle decorations when a tag object referenced
another tag object that was no longer a ref, such as when the second tag was
deleted.  The commit would not be decorated correctly because parse_object had
not been called on the second tag and therefore its tagged field had not been
filled in, resulting in none of the tags being associated with the relevant
commit.

Call parse_object to fill in this field if it is absent so that the chain of
tags can be dereferenced and the commit can be properly decorated.  Include
tests as well to prevent future regressions.

a21bae33d9 diff: let "git diff -O" read orderfile from any file and fail properly
The -O flag really shouldn't silently fail to do anything when given
a path that it can't read from.

However, it should be able to read from un-mmappable files, such as:

 * pipes/fifos

 * /dev/null:  It's a character device (at least on Linux)

 * ANY empty file:

   Quoting Linux mmap(2), "SUSv3 specifies that mmap() should fail if
   length is 0.  However, in kernels before 2.6.12, mmap() succeeded in
   this case: no mapping was created and the call returned addr.  Since
   kernel 2.6.12, mmap() fails with the error EINVAL for this case."

We especially want "-O/dev/null" to work, since we will be documenting
it as the way to cancel "diff.orderfile" when we add that.

(Note: "-O/dev/null" did have the right effect, since the existing error
handling essentially worked out to "silently ignore the orderfile".  But
this was probably more coincidence than anything else.)

So, lets toss all of that logic to get the file mmapped and just use
strbuf_read_file() instead, which gives us decent error handling
practically for free.

e66ef7ae6f Merge branch 'mh/fetch-tags-in-addition-to-normal-refs'
The "--tags" option to "git fetch" used to be literally a synonym to
a "refs/tags/*:refs/tags/*" refspec, which meant that (1) as an
explicit refspec given from the command line, it silenced the lazy
"git fetch" default that is configured, and (2) also as an explicit
refspec given from the command line, it interacted with "--prune"
to remove any tag that the remote we are fetching from does not
have.

This demotes it to an option; with it, we fetch all tags in
addition to what would be fetched without the option, and it does
not interact with the decision "--prune" makes to see what
remote-tracking refs the local has are missing the remote
counterpart.

6df5762db3 diff: don't read index when --no-index is given
git diff --no-index ... currently reads the index, during setup, when
calling gitmodules_config().  This results in worse performance when the
index is not actually needed.  This patch avoids calling
gitmodules_config() when the --no-index option is given.  The times for
executing "git diff --no-index" in the WebKit repository are improved as
follows:

Test                      HEAD~3            HEAD
------------------------------------------------------------------
4001.1: diff --no-index   0.24(0.15+0.09)   0.01(0.00+0.00) -95.8%

An additional improvement of this patch is that "git diff --no-index" no
longer breaks when the index file is corrupt, which makes it possible to
use it for investigating the broken repository.

To improve the possible usage as investigation tool for broken
repositories, setup_git_directory_gently() is also not called when the
--no-index option is given.

Also add a test to guard against future breakages, and a performance
test to show the improvements.

769a4fa463 builtin/replace: unset read_replace_refs
When checking to see if some objects are of the same type
and when displaying the type of objects, git replace uses
the sha1_object_info() function.

Unfortunately this function by default respects replace
refs, so instead of the type of a replaced object, it
gives the type of the replacement object which might
be different.

To fix this bug, and because git replace should work at a
level before replacement takes place, let's unset the
read_replace_refs global variable at the beginning of
cmd_replace().

303c5d65c9 t6050: show that git cat-file --batch fails with replace objects
When --batch is passed to git cat-file, the sha1_object_info_extended()
function is used to get information about the objects passed to
git cat-file.

Unfortunately sha1_object_info_extended() doesn't take care of
object replacement properly, so it will often fail with a
message like this:

$ echo a3fb2e1845a1aaf129b7975048973414dc172173 | git cat-file --batch

6554dfa97a cat-file: handle --batch format with missing type/size
Commit 98e2092 taught cat-file to stream blobs with --batch,
which requires that we look up the object type before
loading it into memory.  As a result, we now print the
object header from information in sha1_object_info, and the
actual contents from the read_sha1_file. We double-check
that the information we printed in the header matches the
content we are about to show.

Later, commit 93d2a60 allowed custom header lines for
--batch, and commit 5b08640 made type lookups optional. As a
result, specifying a header line without the type or size
means that we will not look up those items at all.

This causes our double-checking to erroneously die with an
error; we think the type or size has changed, when in fact
it was simply left at "0".

For the size, we can fix this by only doing the consistency
double-check when we have retrieved the size via
sha1_object_info. In the case that we have not retrieved the
value, that means we also did not print it, so there is
nothing for us to check that we are consistent with.

We could do the same for the type. However, besides our
consistency check, we also care about the type in deciding
whether to stream or not. So instead of handling the case
where we do not know the type, this patch instead makes sure
that we always trigger a type lookup when we are printing,
so that even a format without the type will stream as we
would in the normal case.

now gone and check_everything_connected() should catch the result
incomplete repo. But check_everything_connected() will soon be skipped

0a1bc12b6e receive-pack: allow pushes that update .git/shallow
The basic 8 steps to update .git/shallow does not fully apply here
because the user may choose to accept just a few refs (while fetch
always accepts all refs). The steps are modified a bit.

1-6. same as before. After calling assign_shallow_commits_to_refs at
   step 6, each shallow commit has a bitmap that marks all refs that
   require it.

7. mark all "ours" shallow commits that are reachable from any
   refs. We will need to do the original step 7 on them later.

8. go over all shallow commit bitmaps, mark refs that require new
   shallow commits.

9. setup a strict temporary shallow file to plug all the holes, even
   if it may cut some of our history short. This file is used by all
   hooks. The hooks could use --shallow-file=$GIT_DIR/shallow to
   overcome this and reach everything in current repo.

10. go over the new refs one by one. For each ref, do the reachability
   test if it needs a shallow commit on the list from step 7. Remove
   it if it's reachable from our refs. Gather all required shallow
   commits, run check_everything_connected() with the new ref, then
   install them to .git/shallow.

This mode is disabled by default and can be turned on with
receive.shallowupdate

When "fetch --depth=N" where N exceeds the longest chain of history in

When the source repo is shallow we need to make sure to "unshallow"

reaches its shallow bottom in the source repo.

step 7 and reject refs that require new shallow commits.

Note that, by rejecting refs that require new shallow commits, we
leave dangling objects in the repo, which become "object islands" by
the next "git fetch" of the same source.

If the first fetch our "ours" set is zero and we do practically
nothing at step 7, "ours" is full at the next fetch and we may need to
walk through commits for reachability test. Room for improvement.

ad8261d212 rebase: use reflog to find common base with upstream
Commit 15a147e (rebase: use @{upstream} if no upstream specified,
2011-02-09) says:

	Make it default to 'git rebase @{upstream}'. That is also what
	'git pull [--rebase]' defaults to, so it only makes sense that
	'git rebase' defaults to the same thing.

but that isn't actually the case.  Since commit d44e712 (pull: support
rebased upstream + fetch + pull --rebase, 2009-07-19), pull has actually
chosen the most recent reflog entry which is an ancestor of the current
branch if it can find one.

Add a '--fork-point' argument to git-rebase that can be used to trigger
this behaviour.  This option is turned on by default if no non-option
arguments are specified on the command line, otherwise we treat an
upstream specified on the command-line literally.

c59ab2e52a connect.c: refactor url parsing
Make the function is_local() in transport.c public, rename it into
url_is_local_not_ssh() and use it in both transport.c and connect.c

Use a protocol "local" for URLs for the local file system.

One note about using file:// under Windows:

The (absolute) path on Unix like system typically starts with "/".
When the host is empty, it can be omitted, so that a shell scriptlet
url=file://$pwd
will give a URL like "file:///home/user/repo".

Windows does not have the same concept of a root directory located in "/".
When parsing the URL allow "file://C:/user/repo"
(even if RFC1738 indicates that "file:///C:/user/repo" should be used).

6a59974869 git fetch: support host:/~repo
The documentation (in urls.txt) says that

    "ssh://host:/~repo",
    "host:/~repo" or
    "host:~repo"

specify the repository "repo" in the home directory at "host".

This has not been working for "host:/~repo".

Before commit 356bec "Support [address] in URLs", the comparison
"url != hostname" could be used to determine if the URL had a scheme
or not: "ssh://host/host" != "host".

However, after 356bec "[::1]" was converted into "::1", yielding
url != hostname as well.  To fix this regression, don't use
"if (url != hostname)", but look at the separator instead.

Rename the variable "c" into "separator" to make it easier to read.

1418567381 rev-parse: correctly diagnose revision errors before "--"
Rev-parse understands that a "--" may separate revisions and
filenames, and that anything after the "--" is taken as-is.
However, it does not understand that anything before the
token must be a revision (which is the usual rule
implemented by the setup_revisions parser).

Since rev-parse prefers revisions to files when parsing
before the "--", we end up with the correct result (if such
an argument is a revision, we parse it as one, and if it is
not, it is an error either way).  However, we misdiagnose
the errors:

  $ git rev-parse foobar -- >/dev/null
  fatal: ambiguous argument 'foobar': unknown revision or path not in the working tree.
  Use '--' to separate paths from revisions, like this:
  'git <command> [<revision>...] -- [<file>...]'

  $ >foobar
  $ git rev-parse foobar -- >/dev/null
  fatal: bad flag '--' used after filename

In both cases, we should know that the real error is that
"foobar" is meant to be a revision, but could not be
resolved.

ee7fb0b1d4 difftool: display the number of files in the diff queue in the prompt
When --prompt option is set, git-difftool displays a prompt for each
modified file to be viewed in an external diff program.  At that
point, it could be useful to display a counter and the total number
of files in the diff queue.

Below is the current difftool prompt for the first of 5 modified files:

    Viewing: 'diff.c'
    Launch 'vimdiff' [Y/n]:

Consider the modified prompt:

    Viewing (1/5): 'diff.c'
    Launch 'vimdiff' [Y/n]:

The current GIT_EXTERNAL_DIFF mechanism does not tell the number of
paths in the diff queue nor the current counter.  To make this
"counter/total" info available for GIT_EXTERNAL_DIFF programs
without breaking existing ones by doing the following:

 - Keep track of the number of paths shown so far in diff_options;

 - Export two new environment variables from run_external_diff() to
   show the total number of paths (from diff_queue_struct) and the
   current value of the counter (from diff_options); and

 - Update git-difftool--helper to use these two environment variables.

83786fa412 config: arbitrary number of matches for --unset and --replace-all
git-config used a static match array to hold the matches we want to
unset/replace when using --unset or --replace-all.  Use a
variable-sized array instead.

This in particular fixes the symptoms git-svn had when storing large
numbers of svn-remote.*.added-placeholder entries in the config file.

While the tests are rather more paranoid than just --unset and
--replace-all, the other operations already worked.  Indeed git-svn's
usage only breaks the first time *after* creating so many entries,
when it wants to unset and re-add them all.

1190a1acf8 pack-objects: name pack files after trailer hash
Our current scheme for naming packfiles is to calculate the
sha1 hash of the sorted list of objects contained in the
packfile. This gives us a unique name, so we are reasonably
sure that two packs with the same name will contain the same
objects.

It does not, however, tell us that two such packs have the
exact same bytes. This makes things awkward if we repack the
same set of objects. Due to run-to-run variations, the bytes
may not be identical (e.g., changed zlib or git versions,
different source object reuse due to new packs in the
repository, or even different deltas due to races during a
multi-threaded delta search).

In theory, this could be helpful to a program that cares
that the packfile contains a certain set of objects, but
does not care about the particular representation. In
practice, no part of git makes use of that, and in many
cases it is potentially harmful. For example, if a dumb http
client fetches the .idx file, it must be sure to get the
exact .pack that matches it. Similarly, a partial transfer
of a .pack file cannot be safely resumed, as the actual
bytes may have changed.  This could also affect a local
client which opened the .idx and .pack files, closes the
.pack file (due to memory or file descriptor limits), and
then re-opens a changed packfile.

In all of these cases, git can detect the problem, as we
have the sha1 of the bytes themselves in the pack trailer
(which we verify on transfer), and the .idx file references
the trailer from the matching packfile. But it would be
simpler and more efficient to actually get the correct
bytes, rather than noticing the problem and having to
restart the operation.

This patch simply uses the pack trailer sha1 as the pack
name. It should be similarly unique, but covers the exact
representation of the objects. Other parts of git should not
care, as the pack name is returned by pack-objects and is
essentially opaque.

One test needs to be updated, because it actually corrupts a
pack and expects that re-packing the corrupted bytes will
use the same name. It won't anymore, but we can easily just
use the name that pack-objects hands back.

1a72cfd7fa commit -v: strip diffs and submodule shortlogs from the commit message
When using the '-v' option of "git commit" the diff added to the commit
message temporarily for editing is stripped off after the user exited the
editor by searching for "\ndiff --git " and truncating the commmit message
there if it is found.

But this approach has two problems:

- when the commit message itself contains a line starting with
  "diff --git" it will be truncated there prematurely; and

- when the "diff.submodule" setting is set to "log", the diff may
  start with "Submodule <hash1>..<hash2>", which will be left in
  the commit message while it shouldn't.

Fix that by introducing a special scissor separator line starting with the
comment character ('#' or the core.commentChar config if set) followed by
two lines describing what it is for. The scissor line - which will not be
translated - is used to reliably detect the start of the diff so it can be
chopped off from the commit message, no matter what the user enters there.

Turn a known test failure fixed by this change into a successful test;
also add one for a diff starting with a submodule log and another one for
proper handling of the comment char.

This patch preserves the old "just pass it to the shell" behavior
when a single argument is passed to 'git submodule foreach' and
moves to a new "skip the shell and use the arguments passed
unmolested" behavior when more than one argument is passed.

The old behavior (always concatenating and passing to the shell)
was similar to the 'ssh' command, while the new behavior (switching
on the number of arguments) is what 'xterm -e' does.

May need more thought to make sure this change is advertised well
so that scripts that used multiple arguments but added their own
extra layer of quoting are not broken.

96174145fc t5000: simplify gzip prerequisite checks
In t5000, we test the built-in ".tar.gz" config for
git-archive. To make our tests portable, we check that we
have a way to both gzip and gunzip, and we respected
environment variables to point to alternate commands for
doing these operations.

However, the $GZIP variable did not actually do anything, as
changing it would not affect the baked-in value in
archive-tar.c. Moreover, setting the variable $GZIP
influences gzip itself. From the gzip man page:

  The environment variable GZIP can hold a set of default
  options for gzip. These options are interpreted first and
  can be overwritten by explicit command line parameters.

We could rename this variable, and use it to set up custom
config (or even have a Makefile knob to affect the built
binary), but it is not worth the trouble; nobody has ever
reported a problem with the baked-in default, and they can
always change it via config if they need to. Let's just drop
the variable and use "gzip" in the test (keeping the
prerequisite, of course).

While we're at it, we can drop the GUNZIP variable and
prerequisite; it uses "gzip -d", so if we have GZIP, we
will have both.

We can also use test_lazy_prereq for the gzip prerequisite,
which is simpler and behaves more consistently with the rest
of git (e.g., by making output available when the test is
run with "-v").

would find the 'upstream' branch for the current branch, and then
push the current branch to update it.  However, pushing a single
branch explicitly, i.e.

    $ git push origin $(git symbolic-ref --short HEAD)

would not go through the same ref mapping process, and ends up
updating the branch at 'origin' of the same name, which may not
necessarily be the upstream of the branch being pushed.

In the spirit similar to the previous one, map a colon-less refspec

ca02465b41 push: use remote.$name.push as a refmap
Since f2690487 (fetch: opportunistically update tracking refs,
2013-05-11), we stopped taking a non-storing refspec given on the
command line of "git fetch" literally, and instead started mapping
it via remote.$name.fetch refspecs.  This allows

    $ git fetch origin master

from the 'origin' repository, which is configured with

    [remote "origin"]
        fetch = +refs/heads/*:refs/remotes/origin/*

to update refs/remotes/origin/master with the result, as if the
command line were

    $ git fetch origin +master:refs/remotes/origin/master

to reduce surprises and improve usability.  Before that change, a
refspec on the command line without a colon was only to fetch the
history and leave the result in FETCH_HEAD, without updating the
remote-tracking branches.

When you are simulating a fetch from you by your mothership with a
push by you into your mothership, instead of having:

    [remote "satellite"]
        fetch = +refs/heads/*:refs/remotes/satellite/*

on the mothership repository and running:

    mothership$ git fetch satellite

you would have:

    [remote "mothership"]
        push = +refs/heads/*:refs/remotes/satellite/*

on your satellite machine, and run:

    satellite$ git push mothership

Because we so far did not make the corresponding change to the push
side, this command:

    satellite$ git push mothership master

does _not_ allow you on the satellite to only push 'master' out but
still to the usual destination (i.e. refs/remotes/satellite/master).

Implement the logic to map an unqualified refspec given on the
command line via the remote.$name.push refspec.  This will bring a
bit more symmetry between "fetch" and "push".

ac1fbbda20 submodule: do not copy unknown update mode from .gitmodules
When submodule.$name.update is given as hint from the upstream in
the .gitmodules file, we used to blindly copy it to .git/config,
unless there already is a value defined for the submodule.

However, there is no reason to expect that the update mode hinted by
the upstream is available in the version of Git the user is using,
and a really custom "!cmd" prepared by an upstream person running on
Linux may not even be available to a user on Windows.  It is simply
irresponsible to copy the setting blindly and to attempt to use it
during a later "submodule update" without validating it first.

Just show the suggested value to the diagnostic output, and set the
value to 'none' in the configuration, if it is not one of the ones
that are known to be supported by this version of Git.

11d62145b9 remove #!interpreter line from shell libraries
In a shell snippet meant to be sourced by other shell scripts, an
opening #! line does more harm than good.

The harm:

 - When the shell library is sourced, the interpreter and options from
   the #! line are not used.  Specifying a particular shell can
   confuse the reader into thinking it is safe for the shell library
   to rely on idiosyncrasies of that shell.

 - Using #! instead of a plain comment drops a helpful visual clue
   that this is a shell library and not a self-contained script.

 - Tools such as lintian can use a #! line to tell when an
   installation script has failed by forgetting to set a script
   executable.  This check does not work if shell libraries also start
   with a #! line.

The good:

 - Text editors notice the #! line and use it for syntax highlighting
   if you try to edit the installed scripts (without ".sh" suffix) in
   place.

The use of the #! for file type detection is not needed because Git's
shell libraries are meant to be edited in source form (with ".sh"
suffix).  Replace the opening #! lines with comments.

This involves tweaking the test harness's valgrind support to find
shell libraries by looking for "# " in the first line instead of "#!"
(see v1.7.6-rc3~7, 2011-06-17).

Suggested by Russ Allbery through lintian.  Thanks to Jeff King and
Clemens Buchacher for further analysis.

Tested by searching for non-executable scripts with #! line:

	find . -name .git -prune -o -type f -not -executable |
	while read file
	do
		read line <"$file"
		case $line in
		'#!'*)
			echo "$file"
			;;
		esac
	done

The only remaining scripts found are templates for shell scripts
(unimplemented.sh, wrap-for-bin.sh) and sample input used in tests
(t/t4034/perl/{pre,post}).

c74c72034f test: replace shebangs with descriptions in shell libraries
A #! line in these files is misleading, since these scriptlets are
meant to be sourced with '.' (using whatever shell sources them)
instead of run directly using the interpreter named on the #! line.

Removing the #! line shouldn't hurt syntax highlighting since
these files have filenames ending with '.sh'.  For documentation,
add a brief description of how the files are meant to be used in
place of the shebang line.

b039718d92 drop support for "experimental" loose objects
In git v1.4.3, we introduced a new loose object format that
encoded some object information outside of the zlib stream.
Ultimately the format was dropped in v1.5.3, but we kept the
reading side around to help people migrate objects. Each
time we open a loose object, we use a heuristic to check
whether it is in the normal loose format, or the
experimental one.

This heuristic is robust in the face of valid data, but it
tends to treat corrupted or garbage data as an experimental
object. With the regular format, we would notice quickly
that zlib's crc does not check out and complain. With the
experimental object, we are likely to extract a nonsensical
object size and try to allocate a huge buffer, resulting in
xmalloc calling "die".

This latter behavior is much worse, for two reasons. One,
git reports an allocation error when the real error is
corruption. And two, the program dies unconditionally, so
you cannot even run fsck (which would otherwise ignore the
broken object and keep going).

We could try to improve the heuristic to err on the side of
normal objects in the face of corruption, but there is
really little point. The experimental format is long-dead,
and was never enabled by default to begin with. We can
instead simply remove it. The only affected repository would
be one that explicitly set core.legacyheaders in 2007, and
then never repacked in the intervening 6 years.

361412828a submodule update: remove unnecessary orig_flags variable

on the command line in the "orig_flags" variable to pass them on into the
recursion when the '--recursive' option is given. But this isn't necessary
because all the variables set by the options will be seen in the recursion
too as that is achieved by executing "eval cmd_update".

The same has already been done for cmd_status() in e15bec0ec, so let's
clean up cmd_update() likewise. Also add a test to make sure that a
submodule name given on the command line is not passed into the recursion
(which was the goal of adding the orig_flags variable in 98dbe63db).

2071e05ed2 t5536: new test of refspec conflicts when fetching
Add some tests that "git fetch" handles refspec conflicts (i.e., when
the same local reference should be updated from two different remote
references) correctly.

There is a small bug when updating references opportunistically,
namely that an explicit user wish like

    git fetch origin \
        refs/heads/branch1:refs/remotes/origin/branch2 \
        refs/heads/branch2:refs/remotes/origin/branch1

should override a configured refspec like

    +refs/heads/*:refs/remotes/origin/*

The current code incorrectly treats this as a fatal error.

In a few commits we will improve the error messages for refspec
conflicts in general and also turn this buggy fatal error into a
warning.

0838bf47b3 fetch --prune: prune only based on explicit refspecs
The old behavior of "fetch --prune" was to prune whatever was being
fetched.  In particular, "fetch --prune --tags" caused tags not only
to be fetched, but also to be pruned.  This is inappropriate because
there is only one tags namespace that is shared among the local
repository and all remotes.  Therefore, if the user defines a local
tag and then runs "git fetch --prune --tags", then the local tag is
deleted.  Moreover, "--prune" and "--tags" can also be configured via
fetch.prune / remote.<name>.prune and remote.<name>.tagopt, making it
even less obvious that an invocation of "git fetch" could result in
tag lossage.

Since the command "git remote update" invokes "git fetch", it had the
same problem.

The command "git remote prune", on the other hand, disregarded the
setting of remote.<name>.tagopt, and so its behavior was inconsistent
with that of the other commands.

So the old behavior made it too easy to lose tags.  To fix this
problem, change "fetch --prune" to prune references based only on
refspecs specified explicitly by the user, either on the command line
or via remote.<name>.fetch.  Thus, tags are no longer made subject to
pruning by the --tags option or the remote.<name>.tagopt setting.

However, tags *are* still subject to pruning if they are fetched as
part of a refspec, and that is good.  For example:

* On the command line,

      git fetch --prune 'refs/tags/*:refs/tags/*'

  causes tags, and only tags, to be fetched and pruned, and is
  therefore a simple way for the user to get the equivalent of the old
  behavior of "--prune --tag".

* For a remote that was configured with the "--mirror" option, the
  configuration is set to include

      [remote "name"]
              fetch = +refs/*:refs/*

  , which causes tags to be subject to pruning along with all other
  references.  This is the behavior that will typically be desired for
  a mirror.

c5a84e92a2 fetch --tags: fetch tags *in addition to* other stuff
Previously, fetch's "--tags" option was considered equivalent to
specifying the refspec "refs/tags/*:refs/tags/*" on the command line;
in particular, it caused the remote.<name>.refspec configuration to be
ignored.

But it is not very useful to fetch tags without also fetching other
references, whereas it *is* quite useful to be able to fetch tags *in
addition to* other references.  So change the semantics of this option
to do the latter.

If a user wants to fetch *only* tags, then it is still possible to
specifying an explicit refspec:

    git fetch <remote> 'refs/tags/*:refs/tags/*'

Please note that the documentation prior to 1.8.0.3 was ambiguous
about this aspect of "fetch --tags" behavior.  Commit

    f0cb2f137c 2012-12-14 fetch --tags: clarify documentation

made the documentation match the old behavior.  This commit changes
the documentation to match the new behavior.

01e8d327a9 t3200: do not open a HTML manual page when DEFAULT_MAN_FORMAT is html
We have the build configuration option DEFAULT_MAN_FORMAT to choose a
format different from man pages to be used by 'git help' when no format
is requested explicitly. Since 65db0443 (Set the default help format to
html for msys builds, 2013-06-04) we use html on Windows by default.

There is one test in t3200-branch.sh that invokes a help page. The
intent of the redirections applied to the command invocation is to avoid
that the man page viewer interferes with the automated test. But when
the default format is not "man", this does not have the intended effect,
and the HTML manual page is opened during the test run. Request "man"
format explicitly to keep the test silent.

53039ab154 Avoid difference in tr semantics between System V and BSD
Solaris' tr (both /usr/bin/ and /usr/xpg4/bin) uses the System V
semantics for tr whereby string1's length is truncated to the length
of string2 if string2 is shorter. The BSD semantics, as used by GNU tr
see string2 padded to the length of string1 using the final character
in string2. POSIX explicitly doesn't specify the correct behavior
here, making both equally valid.

This difference means that Solaris' native tr implementations produce
different results for tr ":\t\n" "\0" than GNU tr. This breaks a few
tests in t0008-ignores.sh.

Possible fixes for this are to make string2 be "\0\0\0" or "[\0*]".

Instead, use perl to perform these transliterations which means we
don't need to worry about the difference at all. Since we're replacing
tr with perl, we also use perl to replace the sed invocations used to
transform the files.

Replace four identical transforms with a function named
broken_c_unquote. Replace the other two identical transforms with a
fuction named broken_c_unquote_verbose.

b74cf64803 for-each-ref: avoid loading objects to print %(objectname)
If you ask for-each-ref to print each ref and its object,
like:

  git for-each-ref --format='%(objectname) %(refname)'

this should involve little more work than looking at the ref
files (and packed-refs) themselves. However, for-each-ref
will actually load each object from disk just to print its
sha1. For most repositories, this isn't a big deal, but it
can be noticeable if you have a large number of refs to
print. Here are best-of-five timings for the command above
on a repo with ~10K refs:

  [before]
  real    0m0.112s
  user    0m0.092s
  sys     0m0.016s

  [after]
  real    0m0.014s
  user    0m0.012s
  sys     0m0.000s

This patch checks for %(objectname) and %(objectname:short)
before we actually parse the object (and the rest of the
code is smart enough to avoid parsing if we have filled all
of our placeholders).

Note that we can't simply move the objectname parsing code
into the early loop. If the "deref" form %(*objectname) is
used, then we do need to parse the object in order to peel
the tag. So instead of moving the code, we factor it out
into a separate function that can be called for both cases.

While we're at it, we add some basic tests for the
dereferenced placeholders, which were not tested at all
before. This helps ensure we didn't regress that case.

d96855ff51 merge-base: teach "--fork-point" mode
The "git pull --rebase" command computes the fork point of the
branch being rebased using the reflog entries of the "base" branch
(typically a remote-tracking branch) the branch's work was based on,
in order to cope with the case in which the "base" branch has been
rewound and rebuilt.  For example, if the history looked like this:

                     o---B1
                    /
    ---o---o---B2--o---o---o---Base
            \
             B3
              \
               Derived

where the current tip of the "base" branch is at Base, but earlier
fetch observed that its tip used to be B3 and then B2 and then B1
before getting to the current commit, and the branch being rebased
on top of the latest "base" is based on commit B3, it tries to find
B3 by going through the output of "git rev-list --reflog base" (i.e.
Base, B1, B2, B3) until it finds a commit that is an ancestor of the
current tip "Derived".

Internally, we have get_merge_bases_many() that can compute this
with one-go.  We would want a merge-base between Derived and a
fictitious merge commit that would result by merging all the
historical tips of "base".  When such a commit exist, we should get
a single result, which exactly match one of the reflog entries of
"base".

Teach "git merge-base" a new mode, "--fork-point", to compute
exactly that.

94221d2203 t: use perl instead of "$PERL_PATH" where applicable
As of the last commit, we can use "perl" instead of
"$PERL_PATH" when running tests, as the former is now a
function which uses the latter. As the shorter "perl" is
easier on the eyes, let's switch to using it everywhere.

This is not quite a mechanical s/$PERL_PATH/perl/
replacement, though. There are some places where we invoke
perl from a script we generate on the fly, and those scripts
do not have access to our internal shell functions. The
result can be double-checked by running:

  ln -s /bin/false bin-wrappers/perl
  make test

which continues to pass even after this patch.

a0e0ec9f7d t: provide a perl() function which uses $PERL_PATH
Once upon a time, we assumed that calling a bare "perl" in
the test scripts was OK, because we would find the perl from
the user's PATH, and we were only asking that perl to do
basic operations that work even on old versions of perl.

Later, we found that some systems really prefer to use
$PERL_PATH even for these basic cases, because the system
perl misbehaves in some way (e.g., by handling line endings
differently). We then switched "perl" invocations to
"$PERL_PATH" to respect the user's choice.

Having to use "$PERL_PATH" is ugly and cumbersome, though.
Instead, let's provide a perl() shell function that tests
can use, which will transparently do the right thing.

Unfortunately, test writers still have to use $PERL_PATH in
certain situations, so we still need to keep the advice in
the README.

Note that this may fix test failures in t5004, t5503, t6002,
t6003, t6300, t8001, and t8002, depending on your system's
perl setup. All of these can be detected by running:

  ln -s /bin/false bin-wrappers/perl
  make test

which fails before this patch, and passes after.

f8fc0ee314 t/README: tests can use perl even with NO_PERL
The git build system supports a NO_PERL switch to avoid installing
perl bindings or other features (like "git add --patch") that rely on
perl on runtime, but even with NO_PERL it has not been possible for a
long time to run tests without perl.  Helpers such as

	nul_to_q () {
		"$PERL_PATH" -pe 'y/\000/Q/'
	}

use perl as a better tr or sed and are regularly used in tests without
worrying to add a PERL prerequisite.

Perl is portable enough that it seems fine to keep relying on it for
this kind of thing in tests (and more readable than the alternative of
trying to find POSIXy equivalents).  Update the test documentation to
clarify this.

4a2d5ae262 pathspec: stop --*-pathspecs impact on internal parse_pathspec() uses
Normally parse_pathspec() is used on command line arguments where it
can do fancy thing like parsing magic on each argument or adding magic
for all pathspecs based on --*-pathspecs options.

There's another use of parse_pathspec(), where pathspec is needed, but
the input is known to be pure paths. In this case we usually don't
want --*-pathspecs to interfere. And we definitely do not want to
parse magic in these paths, regardless of --literal-pathspecs.

Add new flag PATHSPEC_LITERAL_PATH for this purpose. When it's set,
--*-pathspecs are ignored, no magic is parsed. And if the caller
allows PATHSPEC_LITERAL (i.e. the next calls can take literal magic),
then PATHSPEC_LITERAL will be set.

This fixes cases where git chokes when GIT_*_PATHSPECS are set because
parse_pathspec() indicates it won't take any magic. But
GIT_*_PATHSPECS add them anyway. These are

   export GIT_LITERAL_PATHSPECS=1
   git blame -- something
   git log --follow something
   git log --merge

"git ls-files --with-tree=path" (aka parse_pathspec() in
overlay_tree_on_cache()) is safe because the input is empty, and
producing one pathspec due to PATHSPEC_PREFER_CWD does not take any
magic into account.

4d715ac05c Windows: a test_cmp that is agnostic to random LF <> CRLF conversions
In a number of tests, output that was produced by a shell script is
compared to expected output using test_cmp. Unfortunately, the MSYS bash--
when invoked via git, such as in hooks--converts LF to CRLF on output
(as produced by echo and printf), which leads to many false positives.

Implements a diff tool that undoes the converted CRLF. To avoid that
sub-processes are spawned (which is very slow on Windows), the tool is
implemented as a shell function. Diff is invoked as usual only when a
difference is detected by the shell code.

b3e9ce1332 reset: pass real rev name to add--interactive
The add--interactive --patch mode adjusts the UI based on
whether we are pulling changes from HEAD or elsewhere (in
the former case it asks to unstage the reverse hunk, rather
than apply the forward hunk).

Commit 166ec2e taught reset to work on an unborn branch, but
in doing so, switched to always providing add--interactive
with the sha1 rather than the symbolic name. This meant we
always used the "apply" interface, even for "git reset -p
HEAD".

We can fix this by passing the symbolic name to
add--interactive.  Since it understands unborn branches
these days, we do not even have to cover this special case
ourselves; we can simply pass HEAD.

The tests in t7105 now check that the right interface is
used in each circumstance (and notice the regression from
166ec2e we are fixing). The test in t7106 checks that we
get this right for the unborn case, too (not a regression,
since it didn't work at all before, but a nice improvement).

68a304d5fe t5510: check that "git fetch --prune --tags" does not prune branches
"git fetch --prune --tags" is currently interpreted as follows:

* "--tags" is equivalent to specifying a refspec
  "refs/tags/*:refs/tags/*", and supersedes any default refspecs
  configured via remote.$REMOTE.fetch.

* "--prune" only operates on the refspecs being fetched.

Therefore, "git fetch --prune --tags" prunes tags in refs/tags/* but
does not fetch or prune other references.  The fact that this command
does not prune references outside of refs/tags/* was previously
untested.  So add a test that verifies the status quo.

However, the status quo is surprising, so it will be changed later in
this patch series.

26a07309a6 Revert "test-lib: support running tests under valgrind in parallel"
This reverts commit ad0e623332.

--valgrind-parallel was broken from the start: during review I made
the whole valgrind setup code conditional on not being a
--valgrind-parallel worker child.  But even the children crucially
need $GIT_VALGRIND to be set; it should therefore have been set
outside the conditional.

The fix would be a two-liner, but since the introduction of the
feature, almost four months have passed without anyone noticing that
it is broken.  So this feature is not worth the about hundred lines of
test-lib.sh complexity.  Revert it.

c8556c6213 Fix calling parse_pathspec with no paths nor PATHSPEC_PREFER_* flags
When parse_pathspec() is called with no paths, the behavior could be
either return no paths, or return one path that is cwd. Some commands
do the former, some the latter. parse_pathspec() itself does not make
either the default and requires the caller to specify either flag if
it may run into this situation.

I've grep'd through all parse_pathspec() call sites. Some pass
neither, but those are guaranteed never pass empty path to
parse_pathspec(). There are two call sites that may pass empty path
and are fixed with this patch.

bca3969534 checkout: proper error message on 'git checkout foo bar --'
The previous code was detecting the presence of "--" by looking only at
argument 1. As a result, "git checkout foo bar --" was interpreted as an
ambiguous file/revision list, and errored out with:

error: pathspec 'foo' did not match any file(s) known to git.
error: pathspec 'bar' did not match any file(s) known to git.
error: pathspec '--' did not match any file(s) known to git.

This patch fixes it by walking through the argument list to find the
"--", and now complains about the number of references given.

a047fafc78 checkout: allow dwim for branch creation for "git checkout $branch --"
The "--" notation disambiguates files and branches, but as a side-effect
of the previous implementation, also disabled the branch auto-creation
when $branch does not exist.

A possible scenario is then:

git checkout $branch
=> fails if $branch is both a ref and a file, and suggests --

git checkout $branch --
=> refuses to create the $branch

This patch allows the second form to create $branch, and since the -- is
provided, it does not look for file named $branch.

4c5baf0273 gc: remove gc.pid file at end of execution
This file isn't really harmful, but isn't useful either, and can create
minor annoyance for the user:

* It's confusing, as the presence of a *.pid file often implies that a
  process is currently running. A user running "ls .git/" and finding
  this file may incorrectly guess that a "git gc" is currently running.

* Leaving this file means that a "git gc" in an already gc-ed repo is
  no-longer a no-op. A user running "git gc" in a set of repositories,
  and then synchronizing this set (e.g. rsync -av, unison, ...) will see
  all the gc.pid files as changed, which creates useless noise.

This patch unlinks the file after the garbage collection is done, so that
gc.pid is actually present only during execution.

Future versions of Git may want to use the information left in the gc.pid
file (e.g. for policies like "don't attempt to run a gc if one has
already been ran less than X hours ago"). If so, this patch can safely be
reverted. For now, let's not bother the users.

056f34bbcd t3600: fix broken "choking git rm" test
The test 'choking "git rm" should not let it die with cruft' is
supposed to check 'git rm's behavior when interrupted by provoking a
SIGPIPE while 'git rm' is busily deleting files from a specially
crafted index.

This test is silently broken for the following reasons:

- The test crafts a special index by feeding a large number of index
  entries with null shas to 'git update-index --index-info'.  It was
  OK back then when this test was introduced in commit 0693f9ddad
  (Make sure lockfiles are unlocked when dying on SIGPIPE,
  2008-12-18), but since commit 4337b5856f (do not write null sha1s to
  on-disk index, 2012-07-28) null shas are not allowed in the on-disk
  index causing 'git update-index' to error out.

- The barfing 'git update-index --index-info' should fail the test,
  but it remains unnoticed because of the severely broken && chain:
  the test's result depends solely on whether there is a stale lock
  file left behind, but after 'git update-index' errors out 'git rm'
  won't be executed at all.

To fix this test feed only non-null shas to 'git update-index' and
restore the && chain (partly by adding a missing && and by using the
test_when_finished helper instead of manual cleanup).

895c5ba3c1 revision: do not peel tags used in range notation
A range notation "A..B" means exactly the same thing as what "^A B"
means, i.e. the set of commits that are reachable from B but not
from A.  But the internal representation after the revision parser
parsed these two notations are subtly different.

 - "rev-list ^A B" leaves A and B in the revs->pending.objects[]
   array, with the former marked as UNINTERESTING and the revision
   traversal machinery propagates the mark to underlying commit
   objects A^0 and B^0.

 - "rev-list A..B" peels tags and leaves A^0 (marked as
   UNINTERESTING) and B^0 in revs->pending.objects[] array before
   the traversal machinery kicks in.

This difference usually does not matter, but starts to matter when
the --objects option is used.  For example, we see this:

    $ git rev-list --objects v1.8.4^1..v1.8.4 | grep $(git rev-parse v1.8.4)
    $ git rev-list --objects v1.8.4 ^v1.8.4^1 | grep $(git rev-parse v1.8.4)
    04f013dc38d7512eadb915eba22efc414f18b869 v1.8.4

With the former invocation, the revision traversal machinery never
hears about the tag v1.8.4 (it only sees the result of peeling it,
i.e. the commit v1.8.4^0), and the tag itself does not appear in the
output.  The latter does send the tag object itself to the output.

Make the range notation keep the unpeeled objects and feed them to
the traversal machinery to fix this inconsistency.

03818a4a94 split_ident: parse timestamp from end of line
Split_ident currently parses left to right. Given this
input:

  Your Name <email@example.com> 123456789 -0500\n

We assume the name starts the line and runs until the first
"<".  That starts the email address, which runs until the
first ">".  Everything after that is assumed to be the
timestamp.

This works fine in the normal case, but is easily broken by
corrupted ident lines that contain an extra ">". Some
examples seen in the wild are:

  1. Name <email>-<> 123456789 -0500\n

  2. Name <email> <Name<email>> 123456789 -0500\n

  3. Name1 <email1>, Name2 <email2> 123456789 -0500\n

Currently each of these produces some email address (which
is not necessarily the one the user intended) and end up
with a NULL date (which is generally interpreted as the
epoch by "git log" and friends).

But in each case we could get the correct timestamp simply
by parsing from the right-hand side, looking backwards for
the final ">", and then reading the timestamp from there.

In general, it's a losing battle to try to automatically
guess what the user meant with their broken crud. But this
particular workaround is probably worth doing.  One, it's
dirt simple, and can't impact non-broken cases. Two, it
doesn't catch a single breakage we've seen, but rather a
large class of errors (i.e., any breakage inside the email
angle brackets may affect the email, but won't spill over
into the timestamp parsing). And three, the timestamp is
arguably more valuable to get right, because it can affect
correctness (e.g., in --until cutoffs).

This patch implements the right-to-left scheme described
above. We adjust the tests in t4212, which generate a commit
with such a broken ident, and now gets the timestamp right.
We also add a test that fsck continues to detect the
breakage.

For reference, here are pointers to the breakages seen (as
numbered above):

050ef3655c remote-curl: rewrite base url from info/refs redirects
For efficiency and security reasons, an earlier commit in
this series taught http_get_* to re-write the base url based
on redirections we saw while making a specific request.

This commit wires that option into the info/refs request,
meaning that a redirect from

    http://example.com/foo.git/info/refs

to

    https://example.com/bar.git/info/refs

will behave as if "https://example.com/bar.git" had been
provided to git in the first place.

The tests bear some explanation. We introduce two new
hierearchies into the httpd test config:

  1. Requests to /smart-redir-limited will work only for the
     initial info/refs request, but not any subsequent
     requests. As a result, we can confirm whether the
     client is re-rooting its requests after the initial
     contact, since otherwise it will fail (it will ask for
     "repo.git/git-upload-pack", which is not redirected).

  2. Requests to smart-redir-auth will redirect, and require
     auth after the redirection. Since we are using the
     redirected base for further requests, we also update
     the credential struct, in order not to mislead the user
     (or credential helpers) about which credential is
     needed. We can therefore check the GIT_ASKPASS prompts
     to make sure we are prompting for the new location.
     Because we have neither multiple servers nor https
     support in our test setup, we can only redirect between
     paths, meaning we need to turn on
     credential.useHttpPath to see the difference.

7202db8647 gitweb test: fix highlight test hang on Linux Mint
Linux Mint has an implementation of the highlight command (unrelated
to the one from http://www.andre-simon.de) that works as a simple
filter. The script uses 'sed' to add terminal colour escape codes
around text matching a regular expression. When t9500-*.sh attempts
to run "highlight --version", the script simply hangs waiting for
input. (See https://bugs.launchpad.net/linuxmint/+bug/815005).

The tool required by gitweb can be installed from the 'highlight'
package. Unfortunately, given the default $PATH, this leads to the
tool having lower precedence than the script.

In order to avoid hanging the test, add '</dev/null' to the command
line of the highlight invocation. Also, since the 'highlight' tool
requred by gitweb produces '--version' output (and the script does
not), saving the command output allows a simple check for the wrong
'highlight'.

mangling does not come from MinGW, but from MSYS [1]. As abd4284 does not

it is passed to main(), give the function the more generic and less
confusing name "print_path".

04c1ee576a mv: Fix spurious warning when moving a file in presence of submodules
In commit 0656781fa "git mv" learned to update the submodule path in the
.gitmodules file when moving a submodule in the work tree. But since that
commit update_path_in_gitmodules() gets called no matter if we moved a
submodule or a regular file, which is wrong and leads to a bogus warning
when moving a regular file in a repo containing a .gitmodules file:

    warning: Could not find section in .gitmodules where path=<filename>

Fix that by only calling update_path_in_gitmodules() when moving a
submodule. To achieve that, we introduce the special SUBMODULE_WITH_GITDIR
define to distinguish the cases where we also have to connect work tree
and git directory from those where we only need to update the .gitmodules
setting.

A test for submodules using a .git directory together with a .gitmodules
file has been added to t7001. Even though newer git versions will always
use a gitfile when cloning submodules, repositories cloned with older git

f849bb6b3b git-svn: Warn about changing default for --prefix in Git v2.0
In Git v2.0, we will change the default --prefix for init/clone from
none/empty to "origin/" (which causes SVN-tracking branches to be
placed at refs/remotes/origin/* instead of refs/remotes/*).

This patch warns users about the upcoming change, both in the git-svn
manual page, and on stderr when running init/clone in the "multi-mode"
without providing a --prefix.

59c2220528 status test: add missing && to <<EOF blocks
When a test forgets to include && after each command, it is possible
for an early command to succeed but the test to fail, which can hide
bugs.

d644c5502f cherry-pick: handle "-" after parsing options
Currently, we only try converting argv[1] from "-" into "@{-1}".  This
means we do not notice "-" when used together with an option.  Worse,
when "git cherry-pick" is run with no options, we segfault.  Fix this
by doing the substitution after we have checked that there is
something in argv to cherry-pick and know any remaining options are
meant for the revision-listing machinery.

This still does not handle "-" after the first non-cherry-pick option.
For example,

	git cherry-pick foo~2 - bar~5

and

	git cherry-pick --no-merges -

will still dump usage.

b0afc02649 checkout test: enable test with complex relative path
This test was added, commented out, in fed1b5ca (git-checkout: Test
for relative path use, 2007-11-09).  Later git's path handling was
improved (d089ebaa, setup: sanitize absolute and funny paths in
get_pathspec(), 2008-01-28) but we forgot to enable the now-working
test.

This test expects to run from a subdirectory, so add a 'cd'.  While
we're here, examine the content of the checked-out file instead of
just checking that it exists.  The other checkout tests already do the
same.

1c4fb136db submodule foreach: skip eval for more than one argument
'eval "$@"' creates an extra layer of shell interpretation, which is
probably not expected by a user who passes multiple arguments to git
submodule foreach:

 $ git grep "'"
 [searches for single quotes]
 $ git submodule foreach git grep "'"
 Entering '[submodule]'
 /usr/lib/git-core/git-submodule: 1: eval: Syntax error: Unterminated quoted string
 Stopping at '[submodule]'; script returned non-zero status.

To fix this, if the user passes more than one argument, execute "$@"
directly instead of passing it to eval.

Examples:

 * Typical usage when adding an extra level of quoting is to pass a
   single argument representing the entire command to be passed to the
   shell.  This doesn't change that.

 * One can imagine someone feeding untrusted input as an argument:

 	git submodule foreach git grep "$variable"

   That currently results in a nonobvious shell code injection
   vulnerability.  Executing the command named by the arguments
   directly, as in this patch, fixes it.
