changes, make should not do anything.

After beffae768a (gitk: Add Chinese (zh_CN) translation, 2017-03-11),
zh_CN.po was introduced. When make was run, a zh_cn.msg file was
generated (notice the lowercase). However, since make is case-sensitive,
it expects zh_CN.po to generate a zh_CN.msg file so make will keep
reattempting to generate a zh_CN.msg so successive make invocations
result in

Generating catalog po/zh_cn.msg
msgfmt --statistics --tcl po/zh_cn.po -l zh_cn -d po/
317 translated messages.

happening continuously.

Rename zh_CN.po to zh_cn.po so that when make generates the zh_cn.msg
file, it will realize that it was successfully generated and only run
once.

git-gui: add horizontal scrollbar to commit buffer

While the commit message widget has a configurable fixed width, it
nevertheless allowed to write commit messages which exceeded this limit.
Though there is no visual clue, that there is scrolling going on. Now
there is a horizontal scrollbar.

There seems to be a bug in at least Tcl/Tk up to version 8.6.8, which
does not update the horizontal scrollbar if one removes the whole
content at once.

git-gui: add hotkeys to set widget focus

The user cannot change focus between the list of files, the diff view and
the commit message widgets without using the mouse (clicking either of
the four widgets).

With this patch, the user may set ui focus to the previously selected path
in either the "Unstaged Changes" or "Staged Changes" widgets, using
ALT+1 or ALT+2.

The user may also set the ui focus to the diff view widget with
ALT+3, or to the commit message widget with ALT+4.

This enables the user to select/unselect files, view the diff and create a
commit in git-gui using keyboard-only.

am: reload .gitattributes after patching it

When applying multiple patches with git am, or when rebasing using the
am backend, it's possible that one of our patches has updated a
gitattributes file. Currently, we cache this information, so if a
file in a subsequent patch has attributes applied, the file will be
written out with the attributes in place as of the time we started the
rebase or am operation, not with the attributes applied by the previous
patch. This problem does not occur when using the -m or -i flags to
rebase.

To ensure we write the correct data into the working tree, expire the
cache after each patch that touches a path ending in ".gitattributes".
Since we load these attributes in multiple separate files, we must
expire them accordingly.

Verify that both the am and rebase code paths work correctly, including
the conflict marker size with am -3.

path: add a function to check for path suffix

We have a function to strip the path suffix from a commit, but we don't
have one to check for a path suffix. For a plain filename, we can use
basename, but that requires an allocation, since POSIX allows it to
modify its argument. Refactor strip_path_suffix into a helper function
and a new function, ends_with_path_components, to meet this need.

transport: teach all vtables to allow fetch first

The only transport that does not allow fetch() to be called before
get_refs_list() is the bundle transport. Clean up the code by teaching
the bundle transport the ability to do this, and removing support for

transport-helper: skip ls-refs if unnecessaryJonathan Tan Wed, 21 Aug 2019 22:20:09 +0000 (15:20 -0700)

transport-helper: skip ls-refs if unnecessary

Commit e70a3030e7 ("fetch: do not list refs if fetching only hashes",
2018-10-07) and its ancestors taught Git, as an optimization, to skip
the ls-refs step when it is not necessary during a protocol v2 fetch
(for example, when lazy fetching a missing object in a partial clone, or
when running "git fetch --no-tags <remote> <SHA-1>"). But that was only
done for natively supported protocols; in particular, HTTP was not
supported.

Teach Git to skip ls-refs when using remote helpers that support connect
or stateless-connect. To do this, fetch() is made an acceptable entry
point. Because fetch() can now be the first function in the vtable
called, "get_helper(transport);" has to be added to the beginning of
that function to set the transport up (if not yet set up) before
process_connect() is invoked.

When fetch() is called, the transport could be taken over (this happens
if "connect" or "stateless-connect" is successfully run without any
"fallback" response), or not. If the transport is taken over, execution
continues like execution for natively supported protocols
(fetch_refs_via_pack() is executed, which will fetch refs using ls-refs
if needed). If not, the remote helper interface will invoke
get_refs_list() if it hasn't been invoked yet, preserving existing
behavior.

t0021: make sure clean filter runsThomas Gummerer Thu, 22 Aug 2019 19:22:40 +0000 (20:22 +0100)

t0021: make sure clean filter runs

In t0021.15 one of the things we are checking is that the clean filter
is run when checking out empty-branch. The clean filter needs to be
run to make sure there are no modifications on the file system for the
test.r file, and thus it isn't dangerous to overwrite it.

However in the current test setup it is not always necessary to run
the clean filter, and thus the test sometimes fails, as debug.log
isn't written.

This happens when test.r has an older mtime than the index itself.
That mtime is also recorded as stat data for test.r in the index, and
based on the heuristic we're using for index entries, git correctly
assumes this file is up-to-date.

Usually this test succeeds because the mtime of test.r is the same as
the mtime of the index. In this case test.r is racily clean, so git
actually checks the contents, for which the clean filter is run.

Fix the test by updating the mtime of test.r, so git is forced to
check the contents of the file, and the clean filter is run as the
test expects.

userdiff: add a builtin pattern for dts files

The Linux kernel receives many patches to the devicetree files each
release. The hunk header for those patches typically show nothing,
making it difficult to figure out what node is being modified without
applying the patch or opening the file and seeking to the context. Let's
add a builtin 'dts' pattern to git so that users can get better diff
output on dts files when they use the diff=dts driver.

The regex has been constructed based on the spec at devicetree.org[1]
and with some help from Johannes Sixt.

line-log: avoid unnecessary full tree diffsSZEDER Gábor Wed, 21 Aug 2019 11:04:24 +0000 (13:04 +0200)

line-log: avoid unnecessary full tree diffs

With rename detection enabled the line-level log is able to trace the
evolution of line ranges across whole-file renames [1]. Alas, to
achieve that it uses the diff machinery very inefficiently, making the
operation very slow [2]. And since rename detection is enabled by
default, the line-level log is very slow by default.

When the line-level log processes a commit with rename detection
enabled, it currently does the following (see queue_diffs()):

1. Computes a full tree diff between the commit and (one of) its
parent(s), i.e. invokes diff_tree_oid() with an empty
'diffopt->pathspec'.
2. Checks whether any paths in the line ranges were modified.
3. Checks whether any modified paths in the line ranges are missing
in the parent commit's tree.
4. If there is such a missing path, then calls diffcore_std() to
figure out whether the path was indeed renamed based on the
previously computed full tree diff.
5. Continues doing stuff that are unrelated to the slowness.

So basically the line-level log computes a full tree diff for each
commit-parent pair in step (1) to be used for rename detection in step
(4) in the off chance that an interesting path is missing from the
parent.

Avoid these expensive and mostly unnecessary full tree diffs by
limiting the diffs to paths in the line ranges. This is much cheaper,
and makes step (2) unnecessary. If it turns out that an interesting
path is missing from the parent, then fall back and compute a full
tree diff, so the rename detection will still work.

Care must be taken when to update the pathspec used to limit the diff
in case of renames. A path might be renamed on one branch and
modified on several parallel running branches, and while processing
commits on these branches the line-level log might have to alternate
between looking at a path's new and old name. However, at any one
time there is only a single 'diffopt->pathspec'.

So add a step (0) to the above to ensure that the paths in the
pathspec match the paths in the line ranges associated with the
currently processed commit, and re-parse the pathspec from the paths
in the line ranges if they differ.

The new test cases include a specially crafted piece of history with
two merged branches and two files, where each branch modifies both
files, renames on of them, and then modifies both again. Then two
separate 'git log -L' invocations check the line-level log of each of
those two files, which ensures that at least one of those invocations
have to do that back-and-forth between the file's old and new name (no
matter which branch is traversed first). 't/t4211-line-log.sh'
already contains two tests involving renames, they don't don't trigger
this back-and-forth.

Avoiding these unnecessary full tree diffs can have huge impact on
performance, especially in big repositories with big trees and mergy
history. Tracing the evolution of a function through the whole
history:

# git.git
$ time git --no-pager log -L:read_alternate_refs:sha1-file.c v2.23.0

Before:

real 0m8.874s
user 0m8.816s
sys 0m0.057s

After:

real 0m2.516s
user 0m2.456s
sys 0m0.060s

# linux.git
$ time ~/src/git/git --no-pager log \
-L:build_restore_work_registers:arch/mips/mm/tlbex.c v5.2

Before:

real 3m50.033s
user 3m48.041s
sys 0m0.300s

After:

real 0m2.599s
user 0m2.466s
sys 0m0.157s

That's just over 88x speedup.

[1] Line-level log's rename following is quite similar to 'git log
--follow path', with the notable differences that it does handle
multiple paths at once as well, and that it doesn't show the
commit performing the rename if it's an exact rename.

[2] This slowness might not have been apparent initially, because back
when the line-level log feature was introduced rename detection
was not yet enabled by default; 12da1d1f6f (Implement line-history
search (git log -L), 2013-03-28) and 5404c116aa (diff: activate
diff.renames by default, 2016-02-25).

diff was taught to batch the fetching of missing objects when operating

pull, fetch: add --set-upstream option

Add the --set-upstream option to git pull/fetch
which lets the user set the upstream configuration
(branch.<current-branch-name>.merge and
branch.<current-branch-name>.remote) for the current branch.

A typical use-case is:

git clone http://example.com/my-public-fork
git remote add main http://example.com/project-main-repo
git pull --set-upstream main master

or, instead of the last line:

git fetch --set-upstream main master
git merge # or git rebase

This is mostly equivalent to cloning project-main-repo (which sets
upsteam) and then "git remote add" my-public-fork, but may feel more
natural for people using a hosting system which allows forking from
the web UI.

This functionality is analog to "git push --set-upstream".

archive-tar: fix pax extended header length calculation

A pax extended header record starts with a decimal number. Its value
is the length of the whole record, including its own length.

The calculation of that number in strbuf_append_ext_header() is off by
one in case the length of the rest is close to a higher order of
magnitude. This affects paths and link targets a bit shorter than 1000,
10000, 100000 etc. characters -- paths with a length of up to 100 fit
into the tar header and don't need a pax extended header.

The mistake has been present since the function was added by ae64bbc18c
("tar-tree: Introduce write_entry()", 2006-03-25).

Account for digits added to len during the loop and keep incrementing
until we have enough space for len and the rest. The crucial change is
to check against the current value of len before each iteration, instead
of against its value before the loop.

diff: 'diff.indentHeuristic' is no longer experimental

The indent heuristic started out as experimental, but it's now our
default diff heuristic since 33de716387 (diff: enable indent heuristic
by default, 2017-05-08). Alas, that commit didn't update the
documentation, and the description of the 'diff.indentHeuristic'
configuration variable still implies that it's experimental and not
the default.

Update the description of 'diff.indentHeuristic' to make it clear that
it's the default diff heuristic.

The description of the related '--indent-heuristic' option has already
been updated in bab76141da (diff: --indent-heuristic is no
longer experimental, 2017-10-29).

repo-settings: create feature.experimental settingDerrick Stolee Tue, 13 Aug 2019 18:37:48 +0000 (11:37 -0700)

repo-settings: create feature.experimental setting

The 'feature.experimental' setting includes config options that are
not committed to become defaults, but could use additional testing.

Update the following config settings to take new defaults, and to
use the repo_settings struct if not already using them:

* 'pack.useSparse=true'

* 'fetch.negotiationAlgorithm=skipping'

In the case of fetch.negotiationAlgorithm, the existing logic
would load the config option only when about to use the setting,
so had a die() statement on an unknown string value. This is
removed as now the config is parsed under prepare_repo_settings().
In general, this die() is probably misplaced and not valuable.
A test was removed that checked this die() statement executed.

repo-settings: create feature.manyFiles setting

The feature.manyFiles setting is suitable for repos with many
files in the working directory. By setting index.version=4 and
core.untrackedCache=true, commands such as 'git status' should
improve.

While adding this setting, modify the index version precedence
tests to check how this setting overrides the default for
index.version is unset.

repo-settings: parse core.untrackedCacheDerrick Stolee Tue, 13 Aug 2019 18:37:46 +0000 (11:37 -0700)

repo-settings: parse core.untrackedCache

The core.untrackedCache config setting is slightly complicated,
so clarify its use and centralize its parsing into the repo
settings.

The default value is "keep" (returned as -1), which persists the
untracked cache if it exists.

If the value is set as "false" (returned as 0), then remove the
untracked cache if it exists.

If the value is set as "true" (returned as 1), then write the
untracked cache and persist it.

Instead of relying on magic values of -1, 0, and 1, split these
options into an enum. This allows the use of "-1" as a
default value. After parsing the config options, if the value is
unset we can initialize it to UNTRACKED_CACHE_KEEP.

commit-graph: turn on commit-graph by default

The commit-graph feature has seen a lot of activity in the past
year or so since it was introduced. The feature is a critical
performance enhancement for medium- to large-sized repos, and
does not significantly hurt small repos.

Change the defaults for core.commitGraph and gc.writeCommitGraph
to true so users benefit from this feature by default.

There are several places in the test suite where the environment
variable GIT_TEST_COMMIT_GRAPH is disabled to avoid reading a
commit-graph, if it exists. The config option overrides the
environment, so swap these. Some GIT_TEST_COMMIT_GRAPH assignments
remain, and those are to avoid writing a commit-graph when a new
commit is created.

t6501: use 'git gc' in quiet mode

t6501-freshen-objects.sh sends the standard error from
'git gc' to a file and verifies that it is empty. This
is intended as a way to ensure no warnings are written
during the operation. However, as the commit-graph is
added as a step to 'git gc', its progress will appear
in the output.

Pass the '-q' argument to avoid a failing test case
when progress is written.

repo-settings: consolidate some config settings

There are a few important config settings that are not loaded
during git_default_config. These are instead loaded on-demand.

Centralize these config options to a single scan, and store
all of the values in a repo_settings struct. The values for
each setting are initialized as negative to indicate "unset".

This centralization will be particularly important in a later
change to introduce "meta" config settings that change the
defaults for these config settings.

worktree remove: clarify error message on dirty worktree

To avoid data loss, 'git worktree remove' refuses to delete a worktree
if it's dirty or contains untracked files. However, the error message
only mentions that the worktree "is dirty", even if the worktree in
question is in fact clean, but contains untracked files:

$ git worktree add test-worktree
Preparing worktree (new branch 'test-worktree')
HEAD is now at aa53e60 Initial
$ >test-worktree/untracked-file
$ git worktree remove test-worktree/
fatal: 'test-worktree/' is dirty, use --force to delete it
$ git -C test-worktree/ diff
$ git -C test-worktree/ diff --cached
$ # Huh? Where are those dirty files?!

Clarify this error message to say that the worktree "contains modified
or untracked files".

completion: complete config variables and values for 'git clone --config='

Completing configuration sections and variable names for the stuck
argument of 'git clone --config=<TAB>' requires a bit of extra care
compared to doing the same for the unstuck argument of 'git clone
--config <TAB>', because we have to deal with that '--config=' being
part of the current word to be completed.

Add an option to the __git_complete_config_variable_name_and_value()
and in turn to the __git_complete_config_variable_name() helper
functions to specify the current section/variable name to be
completed, so they can be used even when completing the stuck argument
of '--config='.

__git_complete_config_variable_value() already has such an option, and
thus no further changes were necessary to complete possible values
after 'git clone --config=section.name=<TAB>'.

completion: complete config variables names and values for 'git clone -c'

The previous commits taught the completion script how to complete
configuration section, variable names, and their valus after 'git -c
<TAB>', and with a bit of foresight encapsulated all that in a
dedicated helper function. Use that function to complete the unstuck
argument of 'git config -c|--config <TAB>', which expect configuration
variables and values in the same 'section.name=value' form.

Note that handling the struck argument for 'git clone --config=<TAB>'
requires some extra care, so it will be done a separate patch.

completion: complete values of configuration variables after 'git -c var='

'git config' expects a configuration variable's name and value in
separate options, so we complete values as they stand on their own on
the command line. 'git -c', however, expects them in a single option
joined by a '=' character, so we should be able to complete values
when they are following 'section.name=' in the same word.

Add new options to the __git_complete_config_variable_value() function
to allow callers to specify the current word to be completed and the
configuration variable whose value is to be completed, and use these
to complete possible values after 'git -c 'section.name=<TAB>'.

completion: complete configuration sections and variable names for 'git -c'

'git config' expects a configuration variable's name and value in
separate arguments, so we let the __gitcomp() helper append a space
character to each variable name by default, like we do for most other
things (--options, refs, paths, etc.). 'git -c', however, expects
them in a single option joined by a '=' character, i.e.
'section.name=value', so we should append a '=' character to each
fully completed variable name, but no space, so the user can continue
typing the value right away.

Add an option to the __git_complete_config_variable_name() function to
allow callers to specify an alternate suffix to add, and use it to
append that '=' character to configuration variables. Update the
__gitcomp() helper function to not append a trailing space to any
completion words ending with a '=', not just to those option with a
stuck argument.

_git_config() contains two enormous case statements, one to complete

completion: simplify inner 'case' pattern in __gitcomp()

The second '*' in the '--*=*' pattern of the inner 'case' statement of
the __gitcomp() helper function never matches anything, so let's use
'--*=' instead.

The purpose of that inner case statement is to decide when to append a
trailing space to the listed options and when not. When an option
requires a stuck argument, i.e. '--option=', then the trailing space
should not be added, so the user can continue typing the required
argument right away. That '--*=*' pattern is supposed to match these
options, but for this purpose that second '*' is unnecessary, a '--*='
pattern works just as well. That second '*' would only make a
difference in case of a possible completion word like
'--option=value', but our completion script never passes such a word
to __gitcomp(), because the '--option=' and its 'value' must be
completed separately.
