The config builtin does its own regex matching of values for the --get,
--get-all, and --get-regexp modes. Plumb the existing 'flags' parameter
to the get_value() method so we can initialize the value-pattern argument
as a fixed string instead of a regex pattern.

The git_config_set_multivar_in_file_gently() and related methods now
take a 'flags' bitfield, so add a new bit representing the --fixed-value
option from 'git config'. This alters the purpose of the value_pattern
parameter to be an exact string match. This requires some initialization
changes in git_config_set_multivar_in_file_gently() and a new strcmp()
call in the matches() method.
The new CONFIG_FLAGS_FIXED_VALUE flag is initialized in builtin/config.c
based on the --fixed-value option, and that needs to be updated in
several callers.
This patch only affects some of the modes of 'git config', and the rest
will be completed in the next change.

The 'git config' builtin takes a 'value-pattern' parameter for several
actions. This can cause confusion when expecting exact value matches
instead of regex matches, especially when the input string contains
metacharacters. While callers can escape the patterns themselves, it
would be more friendly to allow an argument to disable the pattern
matching in favor of an exact string match.
Add a new '--fixed-value' option that does not currently change the
behavior. The implementation will be filled in by later changes for
each appropriate action. For now, check and test that --fixed-value
will abort the command when included with an incompatible action or
without a 'value-pattern' argument.
The name '--fixed-value' was chosen over something simpler like
'--fixed' because some commands allow regular expressions on the
key in addition to the value.

Without additional modifiers, 'git config <key> <value>' attempts
to set a single value in the .git/config file. When the
value-pattern parameter is supplied, this command behaves in a
non-trivial manner.
Consider 'git config <key> <value> <value-pattern>'. The expected
behavior is as follows:
1. If there are multiple existing values that match 'value-pattern',
then the command fails. Users should use --replace-all instead.
2. If there is no existing values match 'value-pattern', then the
'key=value' pair is appended, making this 'key' a multi-valued
config setting.
3. If there is one existing value that matches 'value-pattern', then
the new config has one entry where 'key=value'.
Add a test that demonstrates these options. Break from the existing
pattern in t1300-config.sh to use 'git config --file=<file>' instead of
modifying .git/config directly to prevent possibly incompatible repo
states. Also use 'git config --file=<file> --list' for config state
comparison instead of the config file format. This makes the tests
more readable.

The 'value_regex' argument in the 'git config' builtin is poorly named,
especially related to an upcoming change that allows exact string
matches instead of ERE pattern matches.
Perform a mostly mechanical change of every instance of 'value_regex' to
'value_pattern' in the codebase. This is only critical for documentation
and error messages, but it is best to be consistent inside the codebase,
too.
For documentation, use 'value-pattern' which is better punctuation. This
affects Documentation/git-config.txt and the usage in builtin/config.c,
which was already mixed between 'value_regex' and 'value-regex'.
I gave some thought to leaving the value_regex variables inside config.c
that are regex_t pointers. However, it is probably best to keep the name
consistent with the rest of the variables.
This does not update the translations inside the po/ directory, as that
creates conflicts with ongoing work. The input strings should
automatically update through automation, and a few of the output strings
currently use "[value_regex]" directly.

We will extend the flexibility of the config API. Before doing so, let's
take an existing 'int multi_replace' parameter and replace it with a new
'unsigned flags' parameter that can take multiple options as a bit field.
Update all callers that specified multi_replace to now specify the
CONFIG_FLAGS_MULTI_REPLACE flag. To add more clarity, extend the
documentation of git_config_set_multivar_in_file() including a clear
labeling of its arguments. Other config API methods in config.h require
only a change of the final parameter from 'int' to 'unsigned'.

When a packed object is stored in a multi-pack index, but that pack has
racily gone away, the MIDX code simply calls die(), when it could be
returning an error to the caller, which would in turn lead to
re-scanning the pack directory.
A pack can racily disappear, for example, due to a simultaneous 'git
repack -ad',
You can also reproduce this with two terminals, where one is running:
git init
while true; do
git commit -q --allow-empty -m foo
git repack -ad
git multi-pack-index write
done
(in effect, constantly writing new MIDXs), and the other is running:
obj=$(git rev-parse HEAD)
while true; do
echo $obj | git cat-file --batch-check='%(objectsize:disk)' || break
done
That will sometimes hit the error preparing packfile from
multi-pack-index message, which this patch fixes.
Right now, that path to discovering a missing pack looks something like
'find_pack_entry()' calling 'fill_midx_entry()' and eventually making
its way to call 'nth_midxed_pack_entry()'.
'nth_midxed_pack_entry()' already checks 'is_pack_valid()' and
propagates an error if the pack is invalid. So, this works if the pack
has gone away between calling 'prepare_midx_pack()' and before calling
'is_pack_valid()', but not if it disappears before then.
Catch the case where the pack has already disappeared before
'prepare_midx_pack()' by returning an error in that case, too.

In 17c35c8969 (packfile: skip loading index if in multi-pack-index,
2018-07-12) we stopped loading the .idx file for packs that are
contained within a multi-pack index.
This saves us the effort of loading an .idx and doing some lightweight
validity checks by way of 'packfile.c:load_idx()', but introduces a race
between processes that need to load the index (e.g., to generate a
reverse index) and processes that can delete the index.
For example, running the following in your shell:
$ git init repo && cd repo
$ git commit --allow-empty -m 'base'
$ git repack -ad && git multi-pack-index write
followed by:
$ rm -f .git/objects/pack/pack-*.idx
$ git rev-parse HEAD | git cat-file --batch-check='%(objectsize:disk)'
will result in a segfault prior to this patch. What's happening here is
that we notice that the pack is in the multi-pack index, and so don't
check that it still has a .idx. When we then try and load that index to
generate a reverse index, we don't have it, so the call to
'find_pack_revindex()' in 'packfile.c:packed_object_info()' returns
NULL, and then dereferencing it causes a segfault.
Of course, we don't ever expect someone to remove the index file by
hand, or to be in a state where we never wrote it to begin with (yet
find that pack in the multi-pack-index). But, this can happen in a
timing race with 'git repack -ad', which removes all existing packs
after writing a new pack containing all of their objects.
Avoid this by reverting the hunk of 17c35c8969 which stops loading the
index when the pack is contained in a MIDX. This makes the latter half
of 17c35c8969 useless, since we'll always have a non-NULL
'p->index_data', in which case that if statement isn't guarding
anything.
These two together effectively revert 17c35c8969, and avoid the race
explained above.

Emit a trace2 error event whenever warning() is called, just like when
die(), error(), or usage() is called.
This helps debugging issues that would trigger warnings but not errors.
In particular, this might have helped debugging an issue I encountered
with commit graphs at $DAYJOB [1].
There is a tradeoff between including potentially relevant messages and
cluttering up the trace output produced. I think that warning() messages
should be included in traces, because by its nature, Git is used over
multiple invocations of the Git tool, and a failure (currently traced)
in a Git invocation might be caused by an unexpected interaction in a
previous Git invocation that only has a warning (currently untraced) as
a symptom - as is the case in [1].

A review exchange may begin with a reviewer asking "what did you
mean by this phrase in your log message (or here in the doc)?", the
author answering what was meant, and then the reviewer saying "ah,
that is what you meant---then the flow of the logic makes sense".
But that is not the happy end of the story. New contributors often
forget that the material that has been reviewed in the above exchange
is still unclear in the same way to the next person who reads it,
until it gets updated.
While we are in the vicinity, rephrase the verb "request" used to
refer to comments by reviewers to "suggest"---this matches the
contrast between "original" and "suggested" that appears later in

reviewers are merely helping authors to polish their commits.

Commit 1c1518071c (submodule: use "fetch" logic instead of custom remote
discovery, 2020-11-14) rewrote the logic in fetch_in_submodule to do:
elif test "$2" -ne ""
But this is nonsense in shell: -ne is for numeric comparisons. This
should be "=" or more idiomatically:
elif test -n "$2"
But once we fix that, many tests start failing. Because that commit
introduced another problem. The caller that passes 3 arguments looks
like this:
fetch_in_submodule "$sm_path" $depth "$sha1"
Note the unquoted $depth parameter. When it isn't set, the function will
see only 2 arguments, and the function has no idea if what it sees in $2
is an option to go on the command line, or a refspec to pass on stdin.
In the old code before that commit:
fetch_in_submodule () (
sanitize_submodule_env &&
cd "$1" &&
- case "$2" in
- '')
- git fetch ;;
- *)
- shift
- git fetch $(get_default_remote) "$@" ;;
- esac
we treated those the same, so it didn't matter. But in the new logic
(with my fix above):
+ if test $# -eq 3
+ then
+ echo "$3" | git fetch --stdin "$2"
+ elif test -n "$n"
+ then
+ git fetch "$2"
+ else
+ git fetch
+ fi
we use the number of parameters to distinguish the two. Let's insist
that the caller pass an empty string for positional parameter two if
they want to have a third parameter after it.
But that still leaves one problem. In the --stdin block, we
unconditionally pass "$2" to git-fetch, even if it's the empty string.
Rather than add another conditional, we can use :+ parameter expansion
to include it only if it's non-empty. In fact, we can do the same for
the elif, too, simplifying it further. Technically this is overkill,
since we know the --depth parameter will not have whitespace (and
indeed, most callers do not bother quoting it), but it doesn't hurt for
the function to be careful.
It's somewhat amazing that no tests were failing. I think what happened
is that:
- the 3-arg form rarely triggered; any call with a non-empty $depth
and a $sha1 would work, but one with an empty $depth would only have
2 arguments
- because of the wrong arguments to "test", the shell would complain
and exit non-zero. So we never ran the middle conditional at all
- that left every call running "git fetch" with no arguments. A
well-written test could have detected the distinction here, but in
practice omitting --depth just means fetching more commits, and
fetching everything (rather than a single sha1) works as long as the
commit in question is reachable

The `onbranch` test cases touched by this patch do not actually try to
include any other config. Their purpose is to avoid regressing on two
bugs in the `include.onbranch:<name>.path` code that we fixed in the
past, bugs that are actually unrelated to any concrete branch name.
The first bug was fixed in 85fe0e800c (config: work around bug with
includeif:onbranch and early config, 2019-07-31). Essentially, when
reading early config, there would be a catch-22 trying to access the
refs, and therefore we simply cannot evaluate the condition at that
point. The test case ensures that we avoid emitting this bogus message:
BUG: refs.c:1851: attempting to get main_ref_store outside of repository
The second test case concerns the non-Git scenario, where we simply do
not have a current branch to begin with (because we don't have a
repository in the first place), and the test case was introduced in
22932d9169 (config: stop checking whether the_repository is NULL,
2019-08-06) to ensure that we don't cause a segmentation fault should
the code still incorrectly try to look at any ref.
In short, neither of these two test cases will ever look at a current
branch name, even in case of regressions. Therefore, the actual branch
name does not matter at all. We can therefore easily avoid
racially-charged branch names here, and that's what this patch does.
