The imap-send code was adapted from another project, and
still contains many unused bits of code. One of these bits
contains a type "struct string_list" which bears no
resemblence to the "struct string_list" we use elsewhere in
git. This causes the compiler to complain if git's
string_list ever becomes part of cache.h.
Let's just drop the dead code.

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.
Drop system includes from inet_pton/inet_ntop compatibility wrappers
As both of these compatibility wrappers include git-compat-utils.h,
all of the system includes were redundant.
Dropping these system includes also makes git-compat-utils.h the first
include which avoids a compiler warning on Solaris due to the
redefinition of _FILE_OFFSET_BITS.

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:
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.
"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
their output, and also makes this line translatable.

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.
The date-time parser parses out a human-readble datestring piece by
piece, so that it could even parse a string in a rather strange
notation like 'noon november 11, 2005', but restricts itself from
parsing strings in "<seconds since epoch> <timezone>" format only
for reasonably new timestamps (like 1974 or newer) with 10 or more
digits. This is to prevent a string like "20100917" from getting
interpreted as seconds since epoch (we want to treat it as September
17, 2010 instead) while doing so.
The same codepath is used to read back the timestamp that we have
already recorded in the headers of commit and tag objects; because
of this, such a commit with timestamp "0 +0000" cannot be rebased or
amended very easily.
Teach parse_date() codepath to special case a string of the form
"<digits> +<4-digits>" to work this issue around, but require that
there is no other cruft around the string when parsing a timestamp
of this format for safety.
Note that this has a slight backward incompatibility implications.
If somebody writes "git commit --date='20100917 +0900'" and wants it
to mean a timestamp in September 2010 in Japan, this change will
break such a use case.
This is caused by the fact that localized messages do not have their
place in some RPM package. Let's postpone decision where they should
be put (be it git-i18n-Icelandic, or git-i18n, or git package itself)
for later by removing locale files at the end of install phase.

t0300 creates some helper shell scripts, and marks them with

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.

The current askpass code simply dies if calling an askpass
helper fails. Worse, in some failure modes it doesn't even
print an error (if start_command fails, then it prints its
own error; if reading fails, we print an error; but if the
command exits non-zero, finish_command fails and we print
nothing!).
Let's be more kind to the user by printing an error message
when askpass doesn't work out, and then falling back to the
terminal (which also may fail, of course, but we die already
there with a nice message).
While we're at it, let's clean up the existing error
messages a bit. Now that our prompts are very long and
contain quotes and colons themselves, our error messages are
hard to read.
So the new failure modes look like:
[before, with a terminal]
$ GIT_ASKPASS=false git push
$ echo $?
128
[before, with no terminal, and we must give up]
$ setsid git push
fatal: could not read 'Password for 'https://peff@github.com': ': No such device or address
[after, with a terminal]
$ GIT_ASKPASS=false git push
error: unable to read askpass response from 'false'

gitweb: Allow UTF-8 encoded CGI query parameters and path_info
Gitweb forgot to turn query parameters into UTF-8. This results in a bug
that one cannot search for a string with characters outside US-ASCII. For
example searching for "Michał Kiedrowicz" (containing letter 'ł' - LATIN
SMALL LETTER L WITH STROKE, with Unicode codepoint U+0142, represented
with 0xc5 0x82 bytes in UTF-8 and percent-encoded as %C5%82) result in the
following incorrect data in search field
MichaÅ\202 Kiedrowicz
This is caused by CGI by default treating '0xc5 0x82' bytes as two
characters in Perl legacy encoding latin-1 (iso-8859-1), because 's'
query parameter is not processed explicitly as UTF-8 encoded string.
The solution used here follows "Using Unicode in a Perl CGI script"
article on http://www.lemoda.net/cgi/perl-unicode/index.html:
use CGI;
use Encode 'decode_utf8;
my $value = params('input');
$value = decode_utf8($value);
Decoding UTF-8 is done when filling %input_params hash and $path_info
variable; the former requires to move from explicit $cgi->param(<label>)
to $input_params{<name>} in a few places, which is a good idea anyway.
Also add -override=>1 parameter to $cgi->textfield() invocation in search
form. Otherwise CGI would use values from query string if it is present,
filling value from $cgi->param... without decode_utf8(). As we are using
value of appropriate parameter anyway, -override=>1 doesn't change the
situation but makes gitweb fill search field correctly.
We could simply use the '-utf8' pragma (via "use CGI '-utf8';") to solve
this, but according to CGI.pm documentation, it may cause problems with
POST requests containing binary files, and it requires CGI 3.31 (I think),
released with perl v5.8.9.

The warning appears even when gcc is run without any warning flags

reproduced with -Wtype-limits, which is implied by -Wextra.
On 64-bit architectures it really is possible for a size_t not to be
representable as an off_t so the check this is warning about is not
actually redundant. But even false positives are distracting. Avoid
the warning by making the "len" argument to check_overflow a
uintmax_t; no functional change intended.

There is no reason in principle that an svn-format dump would not be
able to represent a file whose length does not fit in a 32-bit
integer. Use off_t consistently to represent file lengths (in place
of using uint32_t in some contexts) so we can handle that.
Most svn-fe code is already ready to do that without this patch and
passes values of type off_t around. The type mismatch from stragglers
was noticed with gcc -Wtype-limits.
While at it, tighten the parsing of the Text-content-length field to
make sure it is a number and does not overflow, and tighten other
overflow checks as that value is passed around and manipulated.

gitweb: add project_filter to limit project list to a subdirectory
This commit changes the project listing views (project_list,
project_index and opml) to limit the output to only projects in a
subdirectory if the new optional parameter ?pf=directory name is
used.
The implementation of the filter reuses the implementation used for
the 'forks' action (i.e. listing all projects within that directory
from the projects list file (GITWEB_LIST) or only projects in the
given subdirectory of the project root directory without a projects
list file).
Reusing $project instead of adding a new parameter would have been
nicer from a UI point-of-view (including PATH_INFO support) but
would complicate the $project validating code that is currently
being used to ensure nothing is exported that should not be viewable.

gitweb: prepare git_get_projects_list for use outside 'forks'.
Use of the filter option of git_get_projects_list is currently limited
to forks. It currently assumes the project belonging to the filter
directory was already validated to be visible in the project list.
To make it more generic add an optional argument to denote visibility
verification is still needed.
If there is a projects list file (GITWEB_LIST) only projects from
this list are returned anyway, so no more checks needed.
If there is no projects list file and the caller requests strict
checking (GITWEB_STRICT_EXPORT), do not jump directly to the
given directory but instead do a normal search and filter the
results instead.
The only effect of GITWEB_STRICT_EXPORT without GITWEB_LIST is to make
sure no project can be viewed without also be found starting from
project root. git_get_projects_list without this patch does not enforce
this but all callers only call it with a filter already checked this
way. With this parameter a caller can request this check if the filter
cannot be checked this way.

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.
merge: add instructions to the commit message when editing
Before f824628 (merge: use editor by default in interactive sessions,

The sentence about justification is one of the few things about

Recent releases of Redhat/Fedora are reported to ship Perl binary package
with some core modules stripped away (see http://lwn.net/Articles/477234/)
against the upstream Perl5 people's wishes. The Time::HiRes module used by
gitweb one of them.
zsh adds a backslash (foo\ ) for each item in the COMPREPLY array if IFS
doesn't contain spaces. This issue has been reported[1], but there is no
solution yet.
This wasn't a problem due to another bug[2], which was fixed in zsh
version 4.3.12. After this change, 'git checkout ma<tab>' would resolve
to 'git checkout master\ '.
Aditionally, the introduction of __gitcomp_nl in commit a31e626
(completion: optimize refs completion) in git also made the problem
apparent, as Matthieu Moy reported.
The simplest and most generic solution is to hide all the changes we do
to IFS, so that "foo \nbar " is recognized by zsh as "foo bar". This
works on versions of git before and after the introduction of
__gitcomp_nl (a31e626), and versions of zsh before and after 4.3.12.
Once zsh is fixed, we should conditionally disable this workaround to
have the same benefits as bash users.
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.
Check if branches created from old changelists are correctly imported.
Also included some updates to simple branch test so that both are
coherent in respect to each other.

git-p4: Search for parent commit on branch creation
To find out which is its parent the commit of the new branch is compared
sequentially to each blob of the parent branch from the newest to the
oldest. The first blob which results in a zero diff is considered the
parent commit. If none is found, then the commit is applied to the top
of the parent branch.
A fast-import "checkpoint" call is required because diff-tree is only
able to work with blobs on disk. But most of these commits will not be
part of the final imported tree, making fast-import fail. To avoid this,
the temporary branches are tracked and then removed at the end of the
import process.

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.

6f48d39 (clone: delay cloning until after remote HEAD checking -
2012-01-16) allows us to perform some checks on remote refs before the
actual cloning happens. But not all transport types support
this. Remote helper with "import" capability will not return complete
ref information until fetch is performed and therefore the clone cannot
be delayed.
foreign_vcs field in struct remote was used to detect this kind of transport
and save the result. This is a mistake because foreign_vcs is designed
to override url-based transport detection. As a result, if the same
"struct transport *" object is used on many different urls and one of
them attached remote transport, the following urls will be mistakenly
attached to the same transport. This fault is worked around by dad0b3d
(push: do not let configured foreign-vcs permanently clobbered -
2012-01-23)
To fix this, detect incomplete refs from transport_get_remote_refs()
by SHA-1. Incomplete ones must have null SHA-1 (*). Then revert
changes related to foreign_cvs field in 6f48d39 and dad0b3d.
A good thing from this change is that cloning smart http transport can
also be delayed. Earlier it falls into the same category "remote
transport, no delay".
(*) Theoretically if one of the remote refs happens to have null SHA-1,
it will trigger false alarm and the clone will not be delayed. But
that chance may be too small for us to pay attention to.

push: do not let configured foreign-vcs permanently clobbered
Recently, 6f48d39 (clone: delay cloning until after remote HEAD checking,
2012-01-16) tried to record if a remote helper needs to be called after
parsing the remote when transport_get() is called, by overwriting the
field meant to store the configured remote helper name in the remote
structure.
This is OK when a remote represents a single remote repository, but fails
miserably when pushing to locations with multiple URLs, like this:
The right solution would probably be to dedicate a separate field to store
the detected external helper to be used, which is valid only during a
single use of transport until it is disconnected, instead of overwriting
foreign_vcs field, but in the meantime, this band-aid should suffice.

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.

add a Makefile switch to avoid gettext translation in shell scripts
Some systems have gettext.sh (GNU gettext) installed, but it is either
broken or misconfigured in such a way so its output is not usable. In
case the users of these systems are unable or not interested in fixing
them, setting the new Makefile switch should help:
make USE_GETTEXT_SCHEME=fallthrough
This will replace the translation routines with fallthrough versions,
that does not use gettext from the platform.

git-sh-i18n: restructure the logic to compute gettext.sh scheme
Instead of having a single long and complex chain of commands to decide
what to do and carry out the decision, split the code so that we first
decide which scheme to use, and in the second section define what exactly
is done by the chosen scheme. It makes the code much easier to follow and
update.
Some merge tools cannot cope when $LOCAL, $BASE, or $REMOTE are missing.
$BASE can be missing when two branches independently add the same
filename.
Provide an empty file to make these tools happy.
When a delete/modify conflict occurs, $LOCAL and $REMOTE can also be
missing. We have special case code to handle such case so this change
may not affect that codepath, but try to be consistent and create an
empty file for them anyway.

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.

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.
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.

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.

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:
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':
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.
diff-index: enable recursive pathspec matching in unpack_trees
The pathspec structure has a few bits of data to drive various operation
modes after we unified the pathspec matching logic in various codepaths.
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.
