3adab6f3a7 merge: do not launch an editor on "--no-edit $tag"
When the user explicitly asked us not to, don't launch an editor.

But do everything else the same way as the "edit" case, i.e. leave the
comment with verification result in the log template and record the
mergesig in the resulting merge commit for later inspection.

31fd8d72f2 tag: do not show non-tag contents with "-n"
"git tag -n" did not check the type of the object it is reading the top n
lines from. At least, avoid showing the beginning of trees and blobs when
dealing with lightweight tags that point at them.

As the payload of a tag and a commit look similar in that they both start
with a header block, which is skipped for the purpose of "-n" output,
followed by human readable text, allow the message of commit objects to be
shown just like the contents of tag objects. This avoids regression for
people who have been using "tag -n" to show the log messages of commits
that are pointed at by lightweight tags.

Test script is from Jeff King.

3f6d56de5f commit: ignore intent-to-add entries instead of refusing
Originally, "git add -N" was introduced to help users from forgetting to
add new files to the index before they ran "git commit -a".  As an attempt
to help them further so that they do not forget to say "-a", "git commit"
to commit the index as-is was taught to error out, reminding the user that
they may have forgotten to add the final contents of the paths before
running the command.

This turned out to be a false "safety" that is useless.  If the user made
changes to already tracked paths and paths added with "git add -N", and
then ran "git add" to register the final contents of the paths added with
"git add -N", "git commit" will happily create a commit out of the index,
without including the local changes made to the already tracked paths. It
was not a useful "safety" measure to prevent "forgetful" mistakes from
happening.

It turns out that this behaviour is not just a useless false "safety", but
actively hurts use cases of "git add -N" that were discovered later and
have become popular, namely, to tell Git to be aware of these paths added
by "git add -N", so that commands like "git status" and "git diff" would
include them in their output, even though the user is not interested in
including them in the next commit they are going to make.

Fix this ancient UI mistake, and instead make a commit from the index
ignoring the paths added by "git add -N" without adding real contents.

Based on the work by Nguyễn Thái Ngọc Duy, and helped by injection of
sanity from Jonathan Nieder and others on the Git mailing list.

abe199808c git checkout -b: allow switching out of an unborn branch
Running "git checkout -b another" immediately after "git init" when you do
not even have a commit on 'master' fails with:

    $ git checkout -b another
    fatal: You are on a branch yet to be born

This is unnecessary, if we redefine "git checkout -b $name" that does not
take any $start_point (which has to be a commit) as "I want to check out a
new branch $name from the state I am in".

c2d17ba3db branch --edit-description: protect against mistyped branch name
It is very easy to mistype the branch name when editing its description,
e.g.

	$ git checkout -b my-topic master
	: work work work
	: now we are at a good point to switch working something else
	$ git checkout master
	: ah, let's write it down before we forget what we were doing
	$ git branch --edit-description my-tpoic

The command does not notice that branch 'my-tpoic' does not exist.  It is
not lost (it becomes description of an unborn my-tpoic branch), but is not
very useful.  So detect such a case and error out to reduce the grief
factor from this common mistake.

This incidentally also errors out --edit-description when the HEAD points
at an unborn branch (immediately after "init", or "checkout --orphan"),
because at that point, you do not even have any commit that is part of
your history and there is no point in describing how this particular
branch is different from the branch it forked off of, which is the useful
bit of information the branch description is designed to capture.

We may want to special case the unborn case later, but that is outside the
scope of this patch to prevent more common mistakes before 1.7.9 series
gains too much widespread use.

b5c9f1c1b0 merge: do not create a signed tag merge under --ff-only option
Starting at release v1.7.9, if you ask to merge a signed tag, "git merge"
always creates a merge commit, even when the tag points at a commit that
happens to be a descendant of your current commit.

Unfortunately, this interacts rather badly for people who use --ff-only to
make sure that their branch is free of local developments. It used to be
possible to say:

	$ git checkout -b frotz v1.7.9~30
        $ git merge --ff-only v1.7.9

and expect that the resulting tip of frotz branch matches v1.7.9^0 (aka
the commit tagged as v1.7.9), but this fails with the updated Git with:

	fatal: Not possible to fast-forward, aborting.

because a merge that merges v1.7.9 tag to v1.7.9~30 cannot be created by
fast forwarding.

We could teach users that now they have to do

	$ git merge --ff-only v1.7.9^0

but it is far more pleasant for users if we DWIMmed this ourselves.

When an integrator pulls in a topic from a lieutenant via a signed tag,
even when the work done by the lieutenant happens to fast-forward, the
integrator wants to have a merge record, so the integrator will not be
asking for --ff-only when running "git pull" in such a case. Therefore,
this change should not regress the support for the use case v1.7.9 wanted
to add.

7f814632f5 Use correct grammar in diffstat summary line
"git diff --stat" and "git apply --stat" now learn to print the line
"%d files changed, %d insertions(+), %d deletions(-)" in singular form
whenever applicable. "0 insertions" and "0 deletions" are also omitted
unless they are both zero.

This matches how versions of "diffstat" that are not prehistoric produced

2c733fb24c parse_date(): '@' prefix forces git-timestamp
The only place that the issue this series addresses was observed
where we read "cat-file commit" output and put it in GIT_AUTHOR_DATE
in order to replay a commit with an ancient timestamp.

With the previous patch alone, "git commit --date='20100917 +0900'"
can be misinterpreted to mean an ancient timestamp, not September in
year 2010.  Guard this codepath by requring an extra '@' in front of
the raw git timestamp on the parsing side. This of course needs to
be compensated by updating get_author_ident_from_commit and the code
for "git commit --amend" to prepend '@' to the string read from the
existing commit in the GIT_AUTHOR_DATE environment variable.

3d9f5b674f t0300: use write_script helper
t0300 creates some helper shell scripts, and marks them with
"!/bin/sh". Even though the scripts are fairly simple, they
can fail on broken shells (specifically, Solaris /bin/sh
will persist a temporary assignment to IFS in a "read"
command).

Rather than work around the problem for Solaris /bin/sh,
using write_script will make sure we point to a known-good
shell that the user has given us.

840c519d7e tests: add write_script helper function
Many of the scripts in the test suite write small helper
shell scripts to disk. It's best if these shell scripts
start with "#!$SHELL_PATH" rather than "#!/bin/sh", because
/bin/sh on some platforms is too buggy to be used.

However, it can be cumbersome to expand $SHELL_PATH, because
the usual recipe for writing a script is:

	cat >foo.sh <<-\EOF
	#!/bin/sh
	echo my arguments are "$@"
	EOF

To expand $SHELL_PATH, you have to either interpolate the
here-doc (which would require quoting "\$@"), or split the
creation into two commands (interpolating the $SHELL_PATH
line, but not the rest of the script). Let's provide a
helper function that makes that less syntactically painful.

While we're at it, this helper can also take care of the
"chmod +x" that typically comes after the creation of such a
script, saving the caller a line.

b3256eb8b3 standardize and improve lookup rules for external local repos
When you specify a local repository on the command line of
clone, ls-remote, upload-pack, receive-pack, or upload-archive,
or in a request to git-daemon, we perform a little bit of
lookup magic, doing things like looking in working trees for
.git directories and appending ".git" for bare repos.

For clone, this magic happens in get_repo_path. For
everything else, it happens in enter_repo. In both cases,
there are some ambiguous or confusing cases that aren't
handled well, and there is one case that is not handled the
same by both methods.

This patch tries to provide (and test!) standard, sensible
lookup rules for both code paths. The intended changes are:

  1. When looking up "foo", we have always preferred
     a working tree "foo" (containing "foo/.git" over the
     bare "foo.git". But we did not prefer a bare "foo" over
     "foo.git". With this patch, we do so.

  2. We would select directories that existed but didn't
     actually look like git repositories. With this patch,
     we make sure a selected directory looks like a git
     repo. Not only is this more sensible in general, but it
     will help anybody who is negatively affected by change
     (1) negatively (e.g., if they had "foo.git" next to its
     separate work tree "foo", and expect to keep finding
     "foo.git" when they reference "foo").

  3. The enter_repo code path would, given "foo", look for
     "foo.git/.git" (i.e., do the ".git" append magic even
     for a repo with working tree). The clone code path did
     not; with this patch, they now behave the same.

In the unlikely case of a working tree overlaying a bare
repo (i.e., a ".git" directory _inside_ a bare repo), we
continue to treat it as a working tree (prefering the
"inner" .git over the bare repo). This is mainly because the
combination seems nonsensical, and I'd rather stick with
existing behavior on the off chance that somebody is relying
on it.

41b59bfcb1 grep: respect diff attributes for binary-ness
There is currently no way for users to tell git-grep that a
particular path is or is not a binary file; instead, grep
always relies on its auto-detection (or the user specifying
"-a" to treat all binary-looking files like text).

This patch teaches git-grep to use the same attribute lookup
that is used by git-diff. We could add a new "grep" flag,
but that is unnecessarily complex and unlikely to be useful.
Despite the name, the "-diff" attribute (or "diff=foo" and
the associated diff.foo.binary config option) are really
about describing the contents of the path. It's simply
historical that diff was the only thing that cared about
these attributes in the past.

And if this simple approach turns out to be insufficient, we
still have a backwards-compatible path forward: we can add a
separate "grep" attribute, and fall back to respecting
"diff" if it is unset.

2ad9ba0382 request-pull: explicitly ask tags/$name to be pulled
When asking for a tag to be pulled, disambiguate by leaving tags/ prefix
in front of the name of the tag. E.g.

    ... in the git repository at:

      git://example.com/git/git.git/ tags/v1.2.3

    for you to fetch changes up to 123456...

This way, older versions of "git pull" can be used to respond to such a
request more easily, as "git pull $URL v1.2.3" did not DWIM to fetch
v1.2.3 tag in older versions. Also this makes it clearer for humans that
the pull request is made for a tag and he should anticipate a signed one.

This simplifies svn-fe a great deal and fulfills a longstanding wish:
support for dumps with deltas in them, and incremental imports.

The cost is that commandline usage of the svn-fe tool becomes a little
more complicated since it no longer keeps state itself but instead reads
blobs back from fast-import in order to copy them between revisions and
apply deltas to them.

Also removes a couple of custom data structures and replaces them with
strbufs like other parts of Git.

e7d7a56796 t9801: do not overuse test_must_fail
test_must_fail is to make sure a program we can potentially break during
the course of updating git itself exits with a non-zero status in a clean
and controlled way.

When we expect a non-zero exit status from the commands we use from the
underlying platform in tests, e.g. making sure a string "error: " does not
appear in the output by running "grep 'error: '", just use "! grep" for
readability. It is not like we will try to update Git and suddenly 'grep'
we use from the system starts segfaulting.

1017c1abcb submodule add: fix breakage when re-adding a deep submodule
Since recently a submodule with name <name> has its git directory in the
.git/modules/<name> directory of the superproject while the work tree
contains a gitfile pointing there.

When the same submodule is added on a branch where it wasn't present so
far (it is not found in the .gitmodules file), the name is not initialized
from the path as it should. This leads to a wrong path entered in the
gitfile when the .git/modules/<name> directory is found, as this happily
uses the - now empty - name. It then always points only a single directory
up, even if we have a path deeper in the directory hierarchy.

Fix that by initializing the name of the submodule early in module_clone()
if module_name() returned an empty name and add a test to catch that bug.

f8246281af merge: use editor by default in interactive sessions
Traditionally, a cleanly resolved merge was committed by "git merge" using
the auto-generated merge commit log message without invoking the editor.

After 5 years of use in the field, it turns out that people perform too
many unjustified merges of the upstream history into their topic branches.
These merges are not just useless, but they are often not explained well,
and making the end result unreadable when it gets time for merging their
history back to their upstream.

Earlier we added the "--edit" option to the command, so that people can
edit the log message to explain and justify their merge commits. Let's
take it one step further and spawn the editor by default when we are in an
interactive session (i.e. the standard input and the standard output are
pointing at the same tty device).

There may be existing scripts that leave the standard input and the
standard output of the "git merge" connected to whatever environment the
scripts were started, and such invocation might trigger the above
"interactive session" heuristics.  GIT_MERGE_AUTOEDIT environment variable
can be set to "no" at the beginning of such scripts to use the historical
behaviour while the script runs.

Note that this backward compatibility is meant only for scripts, and we
deliberately do *not* support "merge.edit = yes/no/auto" configuration
option to allow people to keep the historical behaviour.

Some merge tools cannot cope when $LOCAL, $BASE, or $REMOTE are missing.
$BASE can be missing when two branches independently add the same

Provide an empty file to make these tools happy.

When a delete/modify conflict occurs, $LOCAL and $REMOTE can also be

may not affect that codepath, but try to be consistent and create an

50dd0f2fd9 grep: fix -l/-L interaction with decoration lines
In threaded mode, git-grep emits file breaks (enabled with context, -W
and --break) into the accumulation buffers even if they are not
required.  The output collection thread then uses skip_first_line to
skip the first such line in the output, which would otherwise be at
the very top.

This is wrong when the user also specified -l/-L/-c, in which case
every line is relevant.  While arguably giving these options together
doesn't make any sense, git-grep has always quietly accepted it.  So
do not skip anything in these cases.

aae5239be2 t/Makefile: Use $(sort ...) explicitly where needed
Starting from GNU Make 3.82 $(wildcard ...) no longer sorts the result
(from NEWS):

    * WARNING: Backward-incompatibility!
      Wildcards were not documented as returning sorted values, but the results
      have been sorted up until this release..  If your makefiles require sorted
      results from wildcard expansions, use the $(sort ...)  function to request
      it explicitly.

    2a59dc32aa

I usually watch test progress visually, and if tests are sorted, even
with make -j4 they go more or less incrementally by their t number. On
the other side, without sorting, tests are executed in seemingly random
order even for -j1. Let's please maintain sane tests order for perceived
prettyness.

Another note is that in GNU Make sort also works as uniq, so after sort
being removed, we might expect e.g. $(wildcard *.sh a.*) to produce
duplicates for e.g. "a.sh". From this point of view, adding sort could
be seen as hardening t/Makefile from accidentally introduced dups.

It turned out that prevous releases of GNU Make did not perform full
sort in $(wildcard), only sorting results for each pattern, that's why
explicit sort-as-uniq is relevant even for older makes.

5238cbf656 remote-curl: Fix push status report when all branches fail
The protocol between transport-helper.c and remote-curl requires
remote-curl to always print a blank line after the push command
has run. If the blank line is ommitted, transport-helper kills its
container process (the git push the user started) with exit(128)
and no message indicating a problem, assuming the helper already
printed reasonable error text to the console.

However if the remote rejects all branches with "ng" commands in the
report-status reply, send-pack terminates with non-zero status, and
in turn remote-curl exited with non-zero status before outputting
the blank line after the helper status printed by send-pack. No
error messages reach the user.

This caused users to see the following from git push over HTTP
when the remote side's update hook rejected the branch:

  $ git push http://... master
  Counting objects: 4, done.
  Delta compression using up to 6 threads.
  Compressing objects: 100% (2/2), done.
  Writing objects: 100% (3/3), 301 bytes, done.
  Total 3 (delta 0), reused 0 (delta 0)
  $

Always print a blank line after the send-pack process terminates,
ensuring the helper status report (if it was output) will be
correctly parsed by the calling transport-helper.c. This ensures
the helper doesn't abort before the status report can be shown to
the user.

36ed1913e1 Making pathspec limited log play nicer with --first-parent
In a topic branch workflow, you often want to find the latest commit that
merged a side branch that touched a particular area of the system, so that
a new topic branch to work on that area can be forked from that commit.
For example, I wanted to find an appropriate fork-point to queue Luke's
changes related to git-p4 in contrib/fast-import/.

"git log --first-parent" traverses the first-parent chain, and "-m --stat"
shows the list of paths touched by commits including merge commits.  We
could ask the question this way:

    # What is the latest commit that touched that path?
    $ git log --first-parent --oneline -m --stat master |
      sed -e '/^ contrib\/fast-import\/git-p4 /q' | tail

The above finds that 8cbfc11 (Merge branch 'pw/p4-view-updates',
2012-01-06) was such a commit.

But a more natural way to spell this question is this:

    $ git log --first-parent --oneline -m --stat -1 master -- \
      contrib/fast-import/git-p4

Unfortunately, this does not work. It finds ecb7cf9 (git-p4: rewrite view
handling, 2012-01-02). This commit is a part of the merged topic branch
and is _not_ on the first-parent path from the 'master':

    $ git show-branch 8cbfc11 ecb7cf9
    ! [8cbfc11] Merge branch 'pw/p4-view-updates'
     ! [ecb7cf9] git-p4: rewrite view handling
    --
    -  [8cbfc11] Merge branch 'pw/p4-view-updates'
    +  [8cbfc11^2] git-p4: view spec documentation
    ++ [ecb7cf9] git-p4: rewrite view handling

The problem is caused by the merge simplification logic when it inspects
the merge commit 8cbfc11. In this case, the history leading to the tip of
'master' did not touch git-p4 since 'pw/p4-view-updates' topic forked, and
the result of the merge is simply a copy from the tip of the topic branch
in the view limited by the given pathspec.  The merge simplification logic
discards the history on the mainline side of the merge, and pretends as if
the sole parent of the merge is its second parent, i.e. the tip of the
topic. While this simplification is correct in the general case, it is at
least surprising if not outright wrong when the user explicitly asked to
show the first-parent history.

Here is an attempt to fix this issue, by not allowing us to compare the
merge result with anything but the first parent when --first-parent is in
effect, to avoid the history traversal veering off to the side branch.

5c8eeb83db diff-index: enable recursive pathspec matching in unpack_trees
The pathspec structure has a few bits of data to drive various operation

For example, max_depth field is there so that "git grep" can limit the
output for files found in limited depth of tree traversal. Also in order
to show just the surface level differences in "git diff-tree", recursive
field stops us from descending into deeper level of the tree structure
when it is set to false, and this also affects pathspec matching when
we have wildcards in the pathspec.

The diff-index has always wanted the recursive behaviour, and wanted to
match pathspecs without any depth limit. But we forgot to do so when we
updated tree_entry_interesting() logic to unify the pathspec matching
logic.

A proper fix would defer such markers until the end of the hunk.
However, word-diff is inherently whitespace-ignoring, so as a cheap

We use a prefix match for '\ ' to parallel the logic in

This is a fundamental problem with how git-p4 only "borrows" a

a file which is already in the repo or explicitly deleted through
another mapping.  To sort this out would involve listing all the
files in the client spec to find one with a higher priority.

1afca44495 attr: don't confuse prefixes with leading directories
When we prepare the attribute stack for a lookup on a path,
we start with the cached stack from the previous lookup
(because it is common to do several lookups in the same
directory hierarchy). So the first thing we must do in
preparing the stack is to pop any entries that point to
directories we are no longer interested in.

For example, if our stack contains gitattributes for:

  foo/bar/baz
  foo/bar
  foo

but we want to do a lookup in "foo/bar/bleep", then we want
to pop the top element, but retain the others.

To do this we walk down the stack from the top, popping
elements that do not match our lookup directory. However,
the test do this simply checked strncmp, meaning we would
mistake "foo/bar/baz" as a leading directory of
"foo/bar/baz_plus". We must also check that the character
after our match is '/', meaning we matched the whole path
component.

There are two special cases to consider:

  1. The top of our attr stack has the empty path. So we
     must not check for '/', but rather special-case the
     empty path, which always matches.

  2. Typically when matching paths in this way, you would
     also need to check for a full string match (i.e., the
     character after is '\0'). We don't need to do so in
     this case, though, because our path string is actually
     just the directory component of the path to a file
     (i.e., we know that it terminates with "/", because the
     filename comes after that).

8b9624c374 Use perl instead of sed for t8006-blame-textconv test
In test 'blame --textconv with local changes' of t8006-blame-textconv,
using /usr/xpg4/bin/sed (as set by SANE_TOOL_PATH), an additional
newline was added to the output from the 'helper' script.

This was noted by sed with a message such as:
sed: Missing newline at end of file zero.bin.

Sed then exits with status 2 causing the helper script to also exit
with status 2.

In turn, this was triggering a fatal error from git blame:
fatal: unable to read files to diff

To work around this difference in sed behaviour, use perl -p instead
of sed -e as it exits cleanly and does not insert the additional
newline.

18ab83e856 gitweb: Fix actionless dispatch for non-existent objects
When gitweb URL does not provide action explicitly, e.g.

  http://git.example.org/repo.git/branch

dispatch() tries to guess action (view to be used) based on remaining
parameters.  Among others it is based on the type of requested object,
which gave problems when asking for non-existent branch or file (for
example misspelt name).

Now undefined $action from dispatch() should not result in problems.

561b133c2c git-daemon tests: wait until daemon is ready
In start_daemon, git-daemon is started as a background process.  In
theory, the tests may try to connect before the daemon had a chance
to open a listening socket. Avoid this race condition by waiting
for it to output "Ready to rumble". Any other output is considered
an error and the test is aborted.

Should git-daemon produce no output at all, lib-git-daemon would
block forever. This could be fixed by introducing a timeout.  On
the other hand, we have no timeout for other git commands which
could suffer from the same problem. Since such a mechanism adds
some complexity, I have decided against it.

c207e34f77 fix push --quiet: add 'quiet' capability to receive-pack
Currently, git push --quiet produces some non-error output, e.g.:

 $ git push --quiet
 Unpacking objects: 100% (3/3), done.

This fixes a bug reported for the fedora git package:

 https://bugzilla.redhat.com/show_bug.cgi?id=725593

Reported-by: Jesse Keating <jkeating@redhat.com>
Cc: Todd Zullinger <tmz@pobox.com>

Commit 90a6c7d4 (propagate --quiet to send-pack/receive-pack)
introduced the --quiet option to receive-pack and made send-pack
pass that option. Older versions of receive-pack do not recognize
the option, however, and terminate immediately. The commit was
therefore reverted.

This change instead adds a 'quiet' capability to receive-pack,
which is a backwards compatible.

In addition, this fixes push --quiet via http: A verbosity of 0
means quiet for remote helpers.

96890f4c42 write first for-merge ref to FETCH_HEAD first
The FETCH_HEAD refname is supposed to refer to the ref that was fetched
and should be merged. However all fetched refs are written to
.git/FETCH_HEAD in an arbitrary order, and resolve_ref_unsafe simply
takes the first ref as the FETCH_HEAD, which is often the wrong one,
when other branches were also fetched.

The solution is to write the for-merge ref(s) to FETCH_HEAD first.
Then, unless --append is used, the FETCH_HEAD refname behaves as intended.
If the user uses --append, they presumably are doing so in order to
preserve the old FETCH_HEAD.

While we are at it, update an old example in the read-tree documentation
that implied that each entry in FETCH_HEAD only has the object name, which
is not true for quite a while.

44df2e2970 stash: Don't fail if work dir contains file named 'HEAD'
When performing a plain "git stash" (without --patch), git-diff would fail
with "fatal: ambiguous argument 'HEAD': both revision and filename". The
output was piped into git-update-index, masking the failed exit status.
The output is now sent to a temporary file (which is cleaned up by
existing code), and the exit status is checked. The "HEAD" arg to the
git-diff invocation has been disambiguated too, of course.

In patch mode, "git stash -p" would fail harmlessly, leaving the working
dir untouched. Interactive adding is fine, but the resulting tree was
diffed with an ambiguous 'HEAD' argument.

Use >foo (no space) when redirecting output.

In t3904, checks and operations on each file are in the order they'll
appear when interactively staging.

In t3905, fix a bug in "stash save --include-untracked -q is quiet": The
redirected stdout file was considered untracked, and so was removed from
the working directory. Use test path helper functions where appropriate.

f032d66ddb request-pull: do not emit "tag" before the tagname
The whole point of the recent update to allow "git pull $url $tagname" is
so that the integrator does not have to store the (signed) tag that is
used to convey authenticity to be recorded in the resulting merge in the
local repository's tag namespace.  Asking for a merge be made with "git
pull $url tag $tagname" defeats it.

Note that the request can become ambiguous if the requestor has a branch
with the same name as the tag, but that is not a new problem limited to
pulling. I wouldn't mind if somebody wants to add disambiguation to the
find_matching_ref logic in the script as a separate patch, though.

02f7914734 remote-curl: don't pass back fake refs
When receive-pack advertises its list of refs, it generally hides the
capabilities information after a NUL at the end of the first ref.

However, when we have an empty repository, there are no refs, and
therefore receive-pack writes a fake ref "capabilities^{}" with the
capabilities afterwards.

On the client side, git reads the result with get_remote_heads(). We pick
the capabilities from the end of the line, and then call check_ref() to
make sure the ref name is valid. We see that it isn't, and don't bother
adding it to our list of refs.

However, the call to check_ref() is enabled by passing the REF_NORMAL flag
to get_remote_heads. For the regular git transport, we pass REF_NORMAL in
get_refs_via_connect() if we are doing a push (since only receive-pack
uses this fake ref).  But in remote-curl, we never use this flag, and we
accept the fake ref as a real one, passing it back from the helper to the
parent git-push.

Most of the time this bug goes unnoticed, as the fake ref won't match our
refspecs. However, if "--mirror" is used, then we see it as remote cruft
to be pruned, and try to pass along a deletion refspec for it. Of course
this refspec has bogus syntax (because of the ^{}), and the helper
complains, aborting the push.

Let's have remote-curl mirror what the builtin get_refs_via_connect() does
(at least for the case of using git protocol; we can leave the dumb
info/refs reader as it is).

This also fixes pushing with --mirror to a smart-http remote that uses
alternates. The fake ".have" refs the server gives to avoid unnecessary
network transfer has a similar bad interactions with the machinery.

bf71009e53 t3502, t3510: clarify cherry-pick -m failure
The "cherry-pick persists opts correctly" test in t3510
(cherry-pick-sequence) can cause some confusion, because the command
actually has two points of failure:

1. "-m 1" is specified on the command-line despite the base commit
   "initial" not being a merge-commit.
2. The revision range indicates that there will be a conflict that
   needs to be resolved.

Although the former error is trapped, and cherry-pick die()s with the
exit status 128, the reader may be distracted by the latter.  Fix this
by changing the revision range to something that wouldn't cause a
conflict.  Additionally, explicitly check the exit code in
"cherry-pick a non-merge with -m should fail" in t3502
(cherry-pick-merge) to reassure the reader that this failure has
nothing to do with the sequencer itself.

c6b7c7f305 t3510 (cherry-pick-sequencer): use exit status
All the tests asserting failure use 'test_must_fail', which simply
checks for a non-zero exit status, potentially hiding underlying bugs.
So, replace instances of 'test_must_fail' with 'test_expect_code' to

37576c1443 commit_tree(): refuse commit messages that contain NULs
Current implementation sees NUL as terminator. If users give a message
with NUL byte in it (e.g. editor set to save as UTF-16), the new commit
message will have NULs. However following operations (displaying or
amending a commit for example) will not keep anything after the first NUL.

Stop user right when they do this. If NUL is added by mistake, they have
their chance to fix. Otherwise, log messages will no longer be text "git
log" and friends would grok.

781f76b158 test-lib: redirect stdin of tests
We want to run tests in a predictable, sterile environment
so we can get repeatable results.  They should take as
little input as possible from the environment outside the
test script. We already sanitize environment variables, but
leave stdin untouched. This means that scripts can
accidentally be impacted by content on stdin, or whether
stdin isatty().

Furthermore, scripts reading from stdin can be annoying to
outer loops which care about their stdin offset, like:

  while read sha1; do
      make test
  done

A test which accidentally reads stdin would soak up all of
the rest of the input intended for the outer shell loop.

Let's redirect stdin from /dev/null, which solves both
of these problems. It won't detect tests accidentally
reading from stdin, but since doing so now gives a
deterministic result, we don't need to consider that an
error.

We'll also leave file descriptor 6 as a link to the original
stdin. Tests shouldn't need to look at this, but it can be
convenient for inserting interactive commands while
debugging tests (e.g., you could insert "bash <&6 >&3 2>&4"
to run interactive commands in the environment of the test
script).

0d16451943 test: errors preparing for a test are not special
This script uses the following idiom to start each test in a known
good state:

	test_expect_success 'some commands use a pager' '
		rm -f paginated.out || cleanup_fail &&
		test_terminal git log &&
		test -e paginated.out
	'

where "cleanup_fail" is a function that prints an error message and
errors out.

That is bogus on three levels:

 - Cleanup commands like "rm -f" and "test_unconfig" are designed not
   to fail, so this logic would never trip.

 - If they were to malfunction anyway, it is not useful to set apart
   cleanup commands as a special kind of failure with a special error
   message.  Whichever command fails, the next step is to investigate
   which command that was, for example by running tests with
   "prove -e 'sh -x'", and fix it.

 - Relying on left-associativity of mixed &&/|| lists makes the code
   somewhat cryptic.

The fix is simple: drop the "|| cleanup_fail" in each test and the
definition of the "cleanup_fail" function so no new callers can arise.

a4ddbc33d7 http-push: enable "proactive auth"
Before commit 986bbc08, git was proactive about asking for
http passwords. It assumed that if you had a username in
your URL, you would also want a password, and asked for it
before making any http requests.

However, this could interfere with the use of .netrc (see
986bbc08 for details). And it was also unnecessary, since
the http fetching code had learned to recognize an HTTP 401
and prompt the user then. Furthermore, the proactive prompt
could interfere with the usage of .netrc (see 986bbc08 for
details).

Unfortunately, the http push-over-DAV code never learned to
recognize HTTP 401, and so was broken by this change. This
patch does a quick fix of re-enabling the "proactive auth"
strategy only for http-push, leaving the dumb http fetch and
smart-http as-is.

0521710a8b t5540: test DAV push with authentication
We don't currently test this case at all, and instead just
test the DAV mechanism over an unauthenticated push. That
isn't very realistic, as most people will want to
authenticate pushes.

Two of the tests expect_failure as they reveal bugs:

  1. Pushing without a username in the URL fails to ask for
     credentials when we get an HTTP 401. This has always
     been the case, but it would be nice if it worked like
     smart-http.

  2. Pushing with a username fails to ask for the password
     since 986bbc0 (http: don't always prompt for password,
     2011-11-04). This is a severe regression in v1.7.8, as
     authenticated push-over-DAV is now totally unusable
     unless you have credentials in your .netrc.

1e7ba0f9ca fetch-pack: match refs exactly
When we are determining the list of refs to fetch via
fetch-pack, we have two sets of refs to compare: those on
the remote side, and a "match" list of things we want to
fetch. We iterate through the remote refs alphabetically,
seeing if each one is wanted by the "match" list.

Since def88e9 (Commit first cut at "git-fetch-pack",
2005-07-04), we have used the "path_match" function to do a
suffix match, where a remote ref is considered wanted if
any of the "match" elements is a suffix of the remote
refname.

This enables callers of fetch-pack to specify unqualified
refs and have them matched up with remote refs (e.g., ask
for "A" and get remote's "refs/heads/A"). However, if you
provide a fully qualified ref, then there are corner cases
where we provide the wrong answer. For example, given a
remote with two refs:

   refs/foo/refs/heads/master
   refs/heads/master

asking for "refs/heads/master" will first match
"refs/foo/refs/heads/master" by the suffix rule, and we will
erroneously fetch it instead of refs/heads/master.

As it turns out, all callers of fetch_pack do provide
fully-qualified refs for the match list. There are two ways
fetch_pack can get match lists:

  1. Through the transport code (i.e., via git-fetch)

  2. On the command-line of git-fetch-pack

In the first case, we will always be providing the names of
fully-qualified refs from "struct ref" objects. We will have
pre-matched those ref objects already (since we have to
handle more advanced matching, like wildcard refspecs), and
are just providing a list of the refs whose objects we need.

In the second case, users could in theory be providing
non-qualified refs on the command-line. However, the
fetch-pack documentation claims that refs should be fully
qualified (and has always done so since it was written in
2005).

Let's change this path_match call to simply check for string
equality, matching what the callers of fetch_pack are

e9d866e32c t5500: give fully-qualified refs to fetch-pack
The fetch-pack documentation is very clear that refs given
on the command line are to be full refs:

  <refs>...::
          The remote heads to update from. This is relative to
          $GIT_DIR (e.g. "HEAD", "refs/heads/master").  When
          unspecified, update from all heads the remote side has.

and this has been the case since fetch-pack was originally documented in
8b3d9dc ([PATCH] Documentation: clone/fetch/upload., 2005-07-14).

Let's follow our own documentation to set a good example,
and to avoid breaking when this restriction is enforced in
the next patch.

861444f6d7 t: add test harness for external credential helpers
We already have tests for the internal helpers, but it's
nice to give authors of external tools an easy way to
sanity-check their helpers.

If you have written the "git-credential-foo" helper, you can
do so with:

  GIT_TEST_CREDENTIAL_HELPER=foo \
  make t0303-credential-external.sh

This assumes that your helper is capable of both storing and
retrieving credentials (some helpers may be read-only, and
they will fail these tests).

If your helper supports time-based expiration with a
configurable timeout, you can test that feature like this:

  GIT_TEST_CREDENTIAL_HELPER_TIMEOUT="foo --timeout=1" \
  make t0303-credential-external.sh

71e1b4b6bf credentials: add "store" helper
This is like "cache", except that we actually put the
credentials on disk. This can be terribly insecure, of
course, but we do what we can to protect them by filesystem
permissions, and we warn the user in the documentation.

This is not unlike using .netrc to store entries, but it's a

place ahead of time, we transparently store them after
prompting the user for them once.

218b65fbf9 revert: do not remove state until sequence is finished
As v1.7.8-rc0~141^2~4 (2011-08-04) explains, git cherry-pick removes
the sequencer state just before applying the final patch.  In the
single-pick case, that was a good thing, since --abort and --continue
work fine without access to such state and removing it provides a
signal that git should not complain about the need to clobber it ("a
cherry-pick or revert is already in progress") in sequences like the
following:

	git cherry-pick foo
	git read-tree -m -u HEAD; # forget that; let's try a different one
	git cherry-pick bar

After the recent patch "allow single-pick in the middle of cherry-pick
sequence" we don't need that hack any more.  In the new regime, a
traditional "git cherry-pick <commit>" command never looks at
.git/sequencer, so we do not need to cripple "git cherry-pick
<commit>..<commit>" for it any more.

So now you can run "git cherry-pick --abort" near the end of a
multi-pick sequence and it will abort the entire sequence, instead of
misbehaving and aborting just the final commit.

7f13334e07 revert: pass around rev-list args in already-parsed form
Since 7e2bfd3f (revert: allow cherry-picking more than one commit,
2010-07-02), the pick/revert machinery has kept track of the set of
commits to be cherry-picked or reverted using commit_argc and
commit_argv variables, storing the corresponding command-line
parameters.

Future callers as other commands are built in (am, rebase, sequencer)
may find it easier to pass rev-list options to this machinery in
already-parsed form.  Teach cmd_cherry_pick and cmd_revert to parse
the rev-list arguments in advance and pass the commit set to
pick_revisions() as a rev_info structure.

093a309136 revert: allow cherry-pick --continue to commit before resuming
When "git cherry-pick ..bar" encounters conflicts, permit the operator
to use cherry-pick --continue after resolving them as a shortcut for
"git commit && git cherry-pick --continue" to record the resolution
and carry on with the rest of the sequence.

This improves the analogy with "git rebase" (in olden days --continue
was the way to preserve authorship when a rebase encountered
conflicts) and fits well with a general UI goal of making "git cmd
--continue" save humans the trouble of deciding what to do next.

Example: after encountering a conflict from running "git cherry-pick
foo bar baz":

	CONFLICT (content): Merge conflict in main.c
	error: could not apply f78a8d98c... bar!
	hint: after resolving the conflicts, mark the corrected paths
	hint: with 'git add <paths>' or 'git rm <paths>'
	hint: and commit the result with 'git commit'

We edit main.c to resolve the conflict, mark it acceptable with "git
add main.c", and can run "cherry-pick --continue" to resume the
sequence.

	$ git cherry-pick --continue
	[editor opens to confirm commit message]
	[master 78c8a8c98] bar!
	 1 files changed, 1 insertions(+), 1 deletions(-)
	[master 87ca8798c] baz!
	 1 files changed, 1 insertions(+), 1 deletions(-)

This is done for both codepaths to pick multiple commits and a single
commit.

e2770979fe credentials: add "cache" helper
If you access repositories over smart-http using http
authentication, then it can be annoying to have git ask you
for your password repeatedly. We cache credentials in
memory, of course, but git is composed of many small
programs. Having to input your password for each one can be
frustrating.

This patch introduces a credential helper that will cache
passwords in memory for a short period of time.

a78fbb4fb6 credential: make relevance of http path configurable
When parsing a URL into a credential struct, we carefully
record each part of the URL, including the path on the
remote host, and use the result as part of the credential
context.

This had two practical implications:

  1. Credential helpers which store a credential for later
     access are likely to use the "path" portion as part of
     the storage key. That means that a request to

       https://example.com/foo.git

     would not use the same credential that was stored in an
     earlier request for:

       https://example.com/bar.git

  2. The prompt shown to the user includes all relevant
     context, including the path.

In most cases, however, users will have a single password
per host. The behavior in (1) will be inconvenient, and the
prompt in (2) will be overly long.

This patch introduces a config option to toggle the
relevance of http paths. When turned on, we use the path as
before. When turned off, we drop the path component from the
context: helpers don't see it, and it does not appear in the
prompt.

This is nothing you couldn't do with a clever credential
helper at the start of your stack, like:

  [credential "http://"]
	helper = "!f() { grep -v ^path= ; }; f"
	helper = your_real_helper

But doing this:

  [credential]
	useHttpPath = false

is way easier and more readable. Furthermore, since most
users will want the "off" behavior, that is the new default.
Users who want it "on" can set the variable (either for all
credentials, or just for a subset using
credential.*.useHttpPath).

118250728e credential: apply helper config
The functionality for credential storage helpers is already
there; we just need to give the users a way to turn it on.
This patch provides a "credential.helper" configuration
variable which allows the user to provide one or more helper
strings.

Rather than simply matching credential.helper, we will also
compare URLs in subsection headings to the current context.
This means you can apply configuration to a subset of
credentials. For example:

  [credential "https://example.com"]
	helper = foo

would match a request for "https://example.com/foo.git", but
not one for "https://kernel.org/foo.git".

This is overkill for the "helper" variable, since users are
unlikely to want different helpers for different sites (and
since helpers run arbitrary code, they could do the matching
themselves anyway).

However, future patches will add new config variables where
this extra feature will be more useful.

148bb6a7b4 http: use credential API to get passwords
This patch converts the http code to use the new credential
API, both for http authentication as well as for getting
certificate passwords.

Most of the code change is simply variable naming (the
passwords are now contained inside the credential struct)
or deletion of obsolete code (the credential code handles
URL parsing and prompting for us).

The behavior should be the same, with one exception: the
credential code will prompt with a description based on the
credential components. Therefore, the old prompt of:

  Username for 'example.com':
  Password for 'example.com':

now looks like:

  Username for 'https://example.com/repo.git':
  Password for 'https://user@example.com/repo.git':

Note that we include more information in each line,
specifically:

  1. We now include the protocol. While more noisy, this is
     an important part of knowing what you are accessing
     (especially if you care about http vs https).

  2. We include the username in the password prompt. This is
     not a big deal when you have just been prompted for it,
     but the username may also come from the remote's URL
     (and after future patches, from configuration or
     credential helpers).  In that case, it's a nice
     reminder of the user for which you're giving the
     password.

  3. We include the path component of the URL. In many
     cases, the user won't care about this and it's simply
     noise (i.e., they'll use the same credential for a
     whole site). However, that is part of a larger
     question, which is whether path components should be
     part of credential context, both for prompting and for
     lookup by storage helpers. That issue will be addressed
     as a whole in a future patch.

Similarly, for unlocking certificates, we used to say:

  Certificate Password for 'example.com':

and we now say:

  Password for 'cert:///path/to/certificate':

Showing the path to the client certificate makes more sense,
as that is what you are unlocking, not "example.com".

abca927dbe introduce credentials API
There are a few places in git that need to get a username
and password credential from the user; the most notable one
is HTTP authentication for smart-http pushing.

Right now the only choices for providing credentials are to
put them plaintext into your ~/.netrc, or to have git prompt
you (either on the terminal or via an askpass program). The
former is not very secure, and the latter is not very
convenient.

Unfortunately, there is no "always best" solution for
password management. The details will depend on the tradeoff
you want between security and convenience, as well as how
git can integrate with other security systems (e.g., many
operating systems provide a keychain or password wallet for
single sign-on).

This patch provides an abstract notion of credentials as a
data item, and provides three basic operations:

  - fill (i.e., acquire from external storage or from the
    user)

  - approve (mark a credential as "working" for further
    storage)

  - reject (mark a credential as "not working", so it can
    be removed from storage)

These operations can be backed by external helper processes
that interact with system- or user-specific secure storage.

a96250c6fb test-lib: add test_config_global variant
The point of test_config is to simultaneously set a config
variable and register its cleanup handler, like:

  test_config core.foo bar

However, it stupidly assumes that $1 contained the name of
the variable, which means it won't work for:

  test_config --global core.foo bar

We could try to parse the command-line ourselves and figure
out which parts need to be fed to test_unconfig. But since
this is likely the most common variant, it's much simpler
and less error-prone to simply add a new function.

  at that stage can be caught.

- Use <<-\EOF in preference to <<EOF to save readers the trouble of
