Add a git-sh-i18n--envsubst program which is a stripped-down version
of the GNU envsubst(1) program that comes with GNU gettext for use in
the eval_gettext() fallback.
We need a C helper program because implementing eval_gettext() purely
in shell turned out to be unworkable. Digging through the Git mailing
list archives will reveal two shell implementations of eval_gettext
that are almost good enough, but fail on an edge case which is tested
for in the tests which are part of this patch.
These are the modifications I made to envsubst.c as I turned it into
sh-i18n--envsubst.c:
* Added our git-compat-util.h header for xrealloc() and friends.
* Removed inclusion of gettext-specific headers.
* Removed most of main() and replaced it with my own. The modified
version only does option parsing for --variables. That's all it
needs.
* Modified error() invocations to use our error() instead of
error(3).
* Replaced the gettext XNMALLOC(n, size) macro with just
xmalloc(n). Since XNMALLOC() only allocated char's.
* Removed the string_list_destroy function. It's redundant (also in
the upstream code).
* Replaced the use of stdbool.h (a C99 header) by doing the following
replacements on the code:
* s/bool/unsigned short int/g
* s/true/1/g
* s/false/0/g

Commands like "git status", "git diff" and "git fetch" would fail when the
.gitmodules file contained merge conflicts because the config parser would
call die() when hitting the conflict markers:
"fatal: bad config file line <n> in <path>/.gitmodules"
While this behavior was on the safe side, it is really unhelpful to the
user to have commands like status and diff fail, as these are needed to
find out what's going on. And the error message is only mildly helpful,
as it points to the right file but doesn't mention that it is unmerged.
Users of git gui were not shown any conflicts at all when this happened.
Improve the situation by checking if the index records .gitmodules as
unmerged. When that is the case we can't make any assumptions about the
configuration to be found there after the merge conflict is resolved by
the user, so assume that all recursion is disabled unless .git/config or
the global config say otherwise.
As soon as the merge conflict is resolved and the .gitmodules file has
been staged subsequent commands again honor any configuration done there.

When adding a new content to the repository, we have always slurped
the blob in its entirety in-core first, and computed the object name
and compressed it into a loose object file. Handling large binary
files (e.g. video and audio asset for games) has been problematic
because of this design.
At the middle level of "git add" callchain is an internal API
index_fd() that takes an open file descriptor to read from the
working tree file being added with its size. Teach it to call out to
fast-import when adding a large blob.
The write-out codepath in entry.c::write_entry() should be taught to
stream, instead of reading everything in core. This should not be so
hard to implement, especially if we limit ourselves only to loose
object files and non-delta representation in packfiles.

Sparse-setting code follows closely how files are excluded in
read_directory(), every entry (including directories) are fed to
excluded_from_list() to decide if the entry is suitable. Directories
are treated no different than files. If a directory is matched (or
not), the whole directory is considered matched (or not) and the
process moves on.
This generally works as long as there are no patterns to exclude parts
of the directory. In case of sparse checkout code, the following patterns
t
!t/t0000-basic.sh
will produce a worktree with full directory "t" even if t0000-basic.sh
is requested to stay out.
By the same reasoning, if a directory is to be excluded, any rules to
re-include certain files within that directory will be ignored.
Fix it by always checking files against patterns. If no pattern can be
used to decide whether an entry is in our out
(ie. excluded_from_list() returns -1), the entry will be
included/excluded the same as their parent directory.

says "word shall be subjected to tilde expansion, parameter expansion,
command substitution, and arithmetic expansion" in ${parameter<op>word},
to mean that the word is expanded as if it appeared in dq pairs, so if the
word were "'$variable'" (sans dq) it would expand to a single quote, the
value of the $variable and then a single quote.
Johannes Sixt reports that the behavior of quoting at the right of :- when
the ${...:-...} expansion appears in double-quotes was debated recently at

Most of git's tests write files and define shell functions and
variables that will last throughout a test script at the top of
the script, before all test assertions:
. ./test-lib.sh
VAR='some value'
export VAR
>empty
fn () {
do something
}
test_expect_success 'setup' '
... nontrivial commands go here ...
'
Two scripts use a different style with this kind of trivial code
enclosed by a test assertion; fix them. The usual style is easier to
read since there is less indentation to keep track of and no need to
worry about nested quotes; and on the other hand, because the commands
in question are trivial, it should not make the test suite any worse
at catching future bugs in git.
While at it, make some other small tweaks:
- spell function definitions with a space before () for consistency
with other scripts;
- use the self-contained command "git mktree </dev/null" in
preference to "git write-tree" which looks at the index when
writing an empty tree.

The merge-one-file tool predates the invention of
GIT_WORK_TREE. By the time GIT_WORK_TREE was invented, most
people were using the merge-recursive strategy, which
handles resolving internally. Therefore these features have
had very little testing together.
For the most part, merge-one-file just works with
GIT_WORK_TREE; most of its heavy lifting is done by plumbing
commands which do respect GIT_WORK_TREE properly. The one
exception is a shell redirection which touches the worktree
directly, writing results to the wrong place in the presence
of a GIT_WORK_TREE variable.
This means that merges won't even fail; they will silently
produce incorrect results, throwing out the entire "theirs"
side of files which need content-level merging!
This patch makes merge-one-file chdir to the toplevel of the
working tree (and exit if we don't have one). This most
closely matches the assumption made by the original script
(before separate work trees were invented), and matches what
happens when the script is called as part of a merge
strategy.
While we're at it, we'll also error-check the call to cat.
Merging a file in a subdirectory could in fact fail, as the
redirection relies on the "checkout-index" call just prior
to create leading directories. But we never noticed, since
we ignored the error return from running cat.

There were no tests for either, except a brief use in

These tools are not used much these days, as most people
use the merge-recursive strategy, which handles everything
internally. However, they are used by the "octopus" and
"resolve" strategies, as well as any custom strategies
or merge scripts people have built around them.
For example, together with read-tree, they are the simplest
way to do a basic content-level merge without checking out
the entire repository contents beforehand.
This script adds a basic test of the tools to perform one
content-level merge. It also shows a failure of the tools to
work properly in the face of GIT_WORK_TREE or core.worktree.

This adds the $projects_list_group_categories option which, if enabled,
will result in grouping projects by category on the project list page.
The category is specified for each project by the $GIT_DIR/category file
or the 'gitweb.category' variable in its configuration file. By default,
projects are put in the $project_list_default_category category.
Note:
- Categories are always sorted alphabetically, with projects in
each category sorted according to the globally selected $order.
- When displaying a subset of all the projects (page limiting), the
category headers are only displayed for projects present on the page.
The feature is inspired from Sham Chukoury's patch for the XMMS2
gitweb, but has been rewritten for the current gitweb code. The CSS
for categories is inspired from Gustavo Sverzut Barbieri's patch to
group projects by path.

Extract filtering out forks (which is done if 'forks' feature is
enabled) into filter_forks_from_projects_list subroutine, and
searching projects (via projects search form, or via content tags)
into search_projects_list subroutine.
Both are now run _before_ displaying projects, and not while printing;
this allow to know upfront if there were any found projects. Gitweb
now can and do print 'No such projects found' if user searches for
phrase which does not correspond to any project (any repository).
This also would allow splitting projects list into pages, if we so
desire.
Filtering out forks and marking repository (project) as having forks
is now consolidated into one subroutine (special case of handling
forks in git_get_projects_list only for $projects_list being file is
now removed). Forks handling is also cleaned up and simplified.
$pr->{'forks'} now contains un-filled list of forks; we can now also
detect situation where the way for having forks is prepared, but there
are no forks yet.
Sorting projects got also refactored in a very straight way (just
moving code) into sort_projects_list subroutine.
The interaction between forks, content tags and searching is now made
more explicit: searching whether by tag, or via search form turns off
fork filtering (gitweb searches also forks, and will show all
results). If 'ctags' feature is disabled, then searching by tag is
too.
The t9500 test now includes some basic test for 'forks' and 'ctags'
features; the t9502 includes test checking if gitweb correctly filters
out forks.
Generating list of projects by scanning given directory is now also a
bit simplified wrt. handling filtering; it is byproduct of extracting
filtering forks to separate subroutine.
While at it we now detect that there are no projects and respond with
"404 No projects found" also for 'project_index' and 'opml' actions.

When encountering errors or unknown tokens while parsing parameters to the
--dirstat option, it makes sense to die() with an error message informing
the user of which parameter did not make sense. However, when parsing the
diff.dirstat config variable, we cannot simply die(), but should instead
(after warning the user) ignore the erroneous or unrecognized parameter.
After all, future Git versions might add more dirstat parameters, and
using two different Git versions on the same repo should not cripple the
older Git version just because of a parameter that is only understood by
a more recent Git version.
This patch fixes the issue by refactoring the dirstat parameter parsing
so that parse_dirstat_params() keeps on parsing parameters, even if an
earlier parameter was not recognized. When parsing has finished, it returns
zero if all parameters were successfully parsed, and non-zero if one or
more parameters were not recognized (with appropriate error messages
appended to the 'errmsg' argument).
The parse_dirstat_params() callers then decide (based on the return value
from parse_dirstat_params()) whether to warn and ignore (in case of
diff.dirstat), or to warn and die (in case of --dirstat).
The patch also adds a couple of tests verifying the correct behavior of
--dirstat and diff.dirstat in the face of unknown (possibly future) dirstat
parameters.

This patch adds an alternative implementation of show_dirstat(), called
show_dirstat_by_line(), which uses the more expensive diffstat analysis
(as opposed to show_dirstat()'s own (relatively inexpensive) analysis)
to derive the numbers from which the --dirstat output is computed.
The alternative implementation is controlled by the new "lines" parameter
to the --dirstat option (or the diff.dirstat config variable).
For binary files, the diffstat analysis counts bytes instead of lines,
so to prevent binary files from dominating the dirstat results, the
byte counts for binary files are divided by 64 before being compared to
their textual/line-based counterparts. This is a stupid and ugly - but
very cheap - heuristic.

yields the following average runtimes on my machine:
- "changes" (default): ~6.0 s
- "lines": ~9.6 s
- "files": ~0.1 s
So, as expected, there's a considerable performance hit (~60%) by going
through the full diffstat analysis as compared to the default "changes"
analysis (obviously, "files" is much faster than both). As such, the
"lines" mode is probably only useful if you really need the --dirstat
numbers to be consistent with the numbers returned from the other
--*stat options.
The patch also includes documentation and tests for the new dirstat mode.

Only the first digit after the decimal point is kept, as the dirstat
calculations all happen in permille.
Selftests verifying floating-point percentage input has been added.

The new diff.dirstat config variable takes the same arguments as
'--dirstat=<args>', and specifies the default arguments for --dirstat.
The config is obviously overridden by --dirstat arguments passed on the
command line.
When not specified, the --dirstat defaults are 'changes,noncumulative,3'.
The patch also adds several tests verifying the interaction between the
diff.dirstat config variable, and the --dirstat command line option.

Instead of having multiple interconnected dirstat-related options, teach
the --dirstat option itself to accept all behavior modifiers as parameters.
- Preserve the current --dirstat=<limit> (where <limit> is an integer
specifying a cut-off percentage)
- Add --dirstat=cumulative, replacing --cumulative
- Add --dirstat=files, replacing --dirstat-by-file
- Also add --dirstat=changes and --dirstat=noncumulative for specifying the
current default behavior. These allow the user to reset other --dirstat
parameters (e.g. 'cumulative' and 'files') occuring earlier on the
command line.
The deprecated options (--cumulative and --dirstat-by-file) are still
functional, although they have been removed from the documentation.
Allow multiple parameters to be separated by commas, e.g.:
--dirstat=files,10,cumulative
Update the documentation accordingly, and add testcases verifying the
behavior of the new syntax.

The expected output from --dirstat=0, is to include any directory with
changes, even if those changes contribute a minuscule portion of the total
changes. However, currently, directories that contribute less than 0.1% are
not included, since their 'permille' value is 0, and there is an
'if (permille)' check in gather_dirstat() that causes them to be ignored.
This test is obviously intended to exclude directories that contribute no
changes whatsoever, but in this case, it hits too broadly. The correct
check is against 'this_dir' from which the permille is calculated. Only if
this value is 0 does the directory truly contribute no changes, and should
be skipped from the output.
This patches fixes this issue, and updates corresponding testcases to
expect the new behvaior.
