config.mak.dev: build with -fno-common
It's an easy mistake to define a variable in a header with "int x;" when
you really meant to only declare the variable as "extern int x;"
instead. Clang and gcc will both allow this when building with
"-fcommon"; they put these "tentative definitions" in a common block
which the linker is able to resolve.
This is the default in clang and was the default in gcc until gcc-10,
since it helps some legacy code. However, we would prefer not to rely on
this because:
- using "extern" makes the intent more clear (so it's a style issue,
but it's one the compiler can help us catch)
- according to the gcc manpage, it may yield a speed and code size
penalty
So let's build explicitly with -fno-common when the DEVELOPER knob is
set, which will let developers using clang and older versions of gcc
notice these problems.
I didn't bother making this conditional on a particular version of gcc.
As far as I know, this option has been available forever in both gcc and
clang, so old versions don't need to avoid it. And we already expect gcc
and clang options throughout config.mak.dev, so it's unlikely anybody
setting the DEVELOPER knob is using anything else. It's a noop on
gcc-10, of course, but it's not worth trying to exclude it there.
Note that there's nothing to fix in the code; we already don't have any
issues here. But if you want to test the patch, you can add a bare "int
x;" into cache.h, which will cause the link step to fail.

fast-import: fix over-allocation of marks storage
Fast-import stores its marks in a trie-like structure made of mark_set
structs. Each struct has a fixed size (1024). If our id number is too
large to fit in the struct, then we allocate a new struct which shifts
the id number by 10 bits. Our original struct becomes a child node
of this new layer, and the new struct becomes the top level of the trie.
This scheme was broken by ddddf8d7e2 (fast-import: permit reading
multiple marks files, 2020-02-22). Before then, we had a top-level
"marks" pointer, and the push-down worked by assigning the new top-level
struct to "marks". But after that commit, insert_mark() takes a pointer
to the mark_set, rather than using the global "marks". It continued to
assign to the global "marks" variable during the push down, which was
wrong for two reasons:
- we added a call in option_rewrite_submodules() which uses a separate
mark set; pushing down on "marks" is outright wrong here. We'd
corrupt the "marks" set, and we'd fail to correctly store any
submodule mappings with an id over 1024.
- the other callers passed "marks", but the push-down was still wrong.
In read_mark_file(), we take the pointer to the mark_set as a
parameter. So even though insert_mark() was updating the global
"marks", the local pointer we had in read_mark_file() was not
updated. As a result, we'd add a new level when needed, but then the
next call to insert_mark() wouldn't see it! It would then allocate a
new layer, which would also not be seen, and so on. Lookups for the
lost layers obviously wouldn't work, but before we even hit any
lookup stage, we'd generally run out of memory and die.
Our tests didn't notice either of these cases because they didn't have
enough marks to trigger the push-down behavior. The new tests in t9304
cover both cases (and fail without this patch).
We can solve the problem by having insert_mark() take a pointer-to-pointer
of the top-level of the set. Then our push down can assign to it in a
way that the caller actually sees. Note the subtle reordering in
option_rewrite_submodules(). Our call to read_mark_file() may modify our
top-level set pointer, so we have to wait until after it returns to
assign its value into the string_list.

commit-graph: don't write commit-graph when disabled
The core.commitGraph config setting can be set to 'false' to prevent
parsing commits from the commit-graph file(s). This causes an issue when
trying to write with "--split" which needs to distinguish between
commits that are in the existing commit-graph layers and commits that
are not. The existing mechanism uses parse_commit() and follows by
checking if there is a 'graph_pos' that shows the commit was parsed from
the commit-graph file.
When core.commitGraph=false, we do not parse the commits from the
commit-graph and 'graph_pos' indicates that no commits are in the
existing file. The --split logic moves forward creating a new layer on
top that holds all reachable commits, then possibly merges down into
those layers, resulting in duplicate commits. The previous change makes
that merging process more robust to such a situation in case it happens
in the written commit-graph data.
The easy answer here is to avoid writing a commit-graph if reading the
commit-graph is disabled. Since the resulting commit-graph will would not
be read by subsequent Git processes. This is more natural than forcing
core.commitGraph to be true for the 'write' process.

commit-graph: ignore duplicates when merging layers
Thomas reported [1] that a "git fetch" command was failing with an error
saying "unexpected duplicate commit id". The root cause is that they had
fetch.writeCommitGraph enabled which generates commit-graph chains, and
this instance was merging two layers that both contained the same commit
ID.
The initial assumption is that Git would not write a commit ID into a
commit-graph layer if it already exists in a lower commit-graph layer.
Somehow, this specific case did get into that situation, leading to this
error.
While unexpected, this isn't actually invalid (as long as the two layers
agree on the metadata for the commit). When we parse a commit that does
not have a graph_pos in the commit_graph_data_slab, we use binary search
in the commit-graph layers to find the commit and set graph_pos. That
position is never used again in this case. However, when we parse a
commit from the commit-graph file, we load its parents from the
commit-graph and assign graph_pos at that point. If those parents were
already parsed from the commit-graph, then nothing needs to be done.
Otherwise, this graph_pos is a valid position in the commit-graph so we
can parse the parents, when necessary.
Thus, this die() is too aggressive. The easiest thing to do would be to
ignore the duplicates.
If we only ignore the duplicates, then we will produce a commit-graph
that has identical commit IDs listed in adjacent positions. This excess
data will never be removed from the commit-graph, which could cascade
into significantly bloated file sizes.
Thankfully, we can collapse the list to erase the duplicate commit
pointers. This allows us to get the end result we want without extra
memory costs and minimal CPU time.
The root cause is due to disabling core.commitGraph, which prevents
parsing commits from the lower layers during a 'git commit-graph write
--split' command. Since we use the 'graph_pos' value to determine
whether a commit is in a lower layer, we never discover that those
commits are already in the commit-graph chain and add them to the top
layer. This layer is then merged down, creating duplicates.
The test added in t5324-split-commit-graph.sh fails without this change.
However, we still have not completely removed the need for this
duplicate check. That will come in a follow-up change.

maintenance: test commit-graph auto condition
The auto condition for the commit-graph maintenance task walks refs
looking for commits that are not in the commit-graph file. This was
added in 4ddc79b2 (maintenance: add auto condition for commit-graph
task, 2020-09-17) but was left untested.
The initial goal of this change was to demonstrate the feature works
properly by adding tests. However, there was an off-by-one error that
caused the basic tests around maintenance.commit-graph.auto=1 to fail
when it should work.
The subtlety is that if a ref tip is not in the commit-graph, then we
were not adding that to the total count. In the test, we see that we
have only added one commit since our last commit-graph write, so the
auto condition would say there is nothing to do.
The fix is simple: add the check for the commit-graph position to see
that the tip is not in the commit-graph file before starting our walk.
Since this happens before adding to the DFS stack, we do not need to
clear our (currently empty) commit list.
This does add some extra complexity for the test, because we also want
to verify that the walk along the parents actually does some work. This
means we need to add at least two commits in a row without writing the
commit-graph. However, we also need to make sure no additional refs are
pointing to the middle of this list or else the for_each_ref() in
should_write_commit_graph() might visit these commits as tips instead of
doing a DFS walk. Hence, the last two commits are added with "git

userdiff: expand detected chunk headers for css
The regex used for the CSS builtin diff driver in git is only
able to show chunk headers for lines that start with a number,
a letter or an underscore.
However, the regex fails to detect classes (starts with a .), ids
(starts with a #), :root and attribute-value based selectors (for
example [class*="col-"]), as well as @based block-level statements
like @page,@keyframes and @media since all of them, start with a
special character.
Allow the selectors and block level statements to begin with these
special characters.

checkout: learn to respect checkout.guess
The current behavior of git checkout/switch is that --guess is currently
enabled by default. However, some users may not wish for this to happen
automatically. Instead of forcing users to specify --no-guess manually
each time, teach these commands the checkout.guess configuration
variable that gives users the option to set a default behavior.
Teach the completion script to recognize the new config variable and
disable DWIM logic if it is set to false.

help: do not expect built-in commands to be hardlinked
When building with SKIP_DASHED_BUILT_INS=YesPlease, the built-in
commands are no longer present in the `PATH` as hardlinks to `git`.
As a consequence, `load_command_list()` needs to be taught to find the
names of the built-in commands from elsewhere.
This only affected the output of `git --list-cmds=main`, but not the
output of `git help -a` because the latter includes the built-in
commands by virtue of them being listed in command-list.txt.
The bug was detected via a patch series that turns the merge strategies
included in Git into built-in commands: `git merge -s help` relies on
`load_command_list()` to determine the list of available merge
strategies.

index-pack: drop type_cas mutex
The type_cas lock lost all of its callers in f08cbf60fe (index-pack:
make quantum of work smaller, 2020-09-08), so we can safely delete it.
The compiler didn't alert us that the variable became unused, because we
still call pthread_mutex_init() and pthread_mutex_destroy() on it.
It's worth considering also whether that commit was in error to remove
the use of the lock. Why don't we need it now, if we did before, as
described in ab791dd138 (index-pack: fix race condition with duplicate
bases, 2014-08-29)? I think the answer is that we now look at and assign
the child_obj->real_type field in the main thread while holding the
work_lock(). So we don't have to worry about racing with the worker
threads.

index-pack: restore "resolving deltas" progress meter
Commit f08cbf60fe (index-pack: make quantum of work smaller, 2020-09-08)
refactored the main loop in threaded_second_pass(), but also deleted the
call to display_progress() at the top of the loop. This means that users
typically see no progress at all during the delta resolution phase (and
for large repositories, Git appears to hang).
This looks like an accident that was unrelated to the intended change of
that commit, since we continue to update nr_resolved_deltas in
resolve_delta(). Let's restore the call to get that progress back.
We'll also add a test that confirms we generate the expected progress.
This isn't perfect, as it wouldn't catch a bug where progress was
delayed to the end. That was probably possible to trigger when receiving
a thin pack, because we'd eventually call display_progress() from
fix_unresolved_deltas(), but only once after doing all the work.
However, since our test case generates a complete pack, it reliably
demonstrates this particular bug and its fix. And we can't do better
without making the test racy.

GitHub workflow: automatically follow minor updates of setup-msbuild
It is the custom to follow minor updates of GitHub Actions
automatically, by using the suffix `@v1`. Actions' maintainers will then
update that `v1` ref to point to the newest.
However, for `microsoft/setup-msbuild`, 889cacb6897 (ci: configure
GitHub Actions for CI/PR, 2020-04-11) uses a very specific `@v1.0.0`
suffix.
In this instance, that is a problem: should `setup-msbuild` release a
new version that intends to fix a critical bug, we won't know it, and we
won't use it.
Such a scenario is not theoretical. It is happening right now:
https://github.blog/changelog/2020-10-01-github-actions-deprecating-set-env-and-add-path-commands

The colors of some ttext widgets are hard-coded. These hard-coded colors
are okay with a light theme but with a dark theme some widgets are dark
colored and the hard-coded ones are still light. This defeats the
purpose of applying the theme and makes the UI look very awkward.
Remove the hard-coded colors in ttext calls and use colors from the
theme for those widgets via Text.Background and Text.Foreground from the
option database.
Similarly, the highlighting for the currently selected file(s) in the
"Staged Files" and "Unstaged Files" sections is also hard-coded. Pull
the colors for that from the current theme to make sure it is in line
On atomic pushing failure with GnuPG, we expect a very specific output
in stdout due to `--porcelain` switch.
On such failure, we also write down some helpful hint into stderr
in order to help user understand what happens and how to continue from
those failures.
On a lot of system, those hint (in stderr) will be flushed first,
then those messages in stdout will be flushed. In such systems, the
current test code is fine as is.
However, we don't have such guarantee, (at least) there're some real
systems that writes those stream interleaved. On such systems, we may
see the stderr stream written in the middle of stdout stream.
Let's split those stream redirection. By splitting those stream,
the output stream will contain exactly what we want to compare,
thus, saving us a "sed" invocation.
While we're at it, change the `test_i18ncmp` to `test_cmp` because we
will never translate those messages (because of `--porcelain`).
