The recent glibc 2.43 release had the following change listed in its
NEWS file:
For ISO C23, the functions bsearch, memchr, strchr, strpbrk, strrchr,
strstr, wcschr, wcspbrk, wcsrchr, wcsstr and wmemchr that return
pointers into their input arrays now have definitions as macros that
return a pointer to a const-qualified type when the input argument is
a pointer to a const-qualified type.
When compiling with GCC 15, which defaults to -std=gnu23, this causes
many warnings like this:
merge-ort.c: In function ‘apply_directory_rename_modifications’:
merge-ort.c:2734:36: warning: initialization discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
2734 | char *last_slash = strrchr(cur_path, '/');
| ^~~~~~~
This patch fixes the more obvious ones by making them const when we do
not write to the returned pointer.

Code clean-up.
* rs/parse-config-expiry-simplify:
config: use git_parse_int() in git_config_get_expiry_in_days()
|
|
git_config_get_expiry_in_days() calls git_parse_signed() with the
maximum value of int, which is equivalent to calling git_parse_int().
Do that instead, as its shorter and clearer.
This requires demoting "days" to int to match. Promote "scale" to
intmax_t in turn to arrive at the same result when multiplying them.

"git config get --path" segfaulted on an ":(optional)path" that
does not exist, which has been corrected.
* jc/optional-path:
config: really treat missing optional path as not configured
config: really pretend missing :(optional) value is not there
config: mark otherwise unused function as file-scope static
|
|
Earlier we added support for a value spelled as ":(optional)path"
for configuration variables whose values are of type "path", with
the documented semantics "if the path is missing, behave as if such
a variable definition is not even there."
This has worked OK for code paths that reads configuration files and
stores the configured value as a string, where NULL in such a string
is treated as if the setting is not there, left as the default.
However, there are other code paths that do not _ignore_ such NULL
values and misbehave. "git config get --path" is one of them.
When git_config_pathname() helper function finds that the value of
the variable is an optional path *and* the path is missing, it
leaves the destination pointer intact (which usually is left to
NULL) and returns 0 to signal a success. format_config() helper
however assumed that the destination pointer always gets a string,
which no longer is the case, and segfaulted.
Make sure that git_config_pathname() clears the destination pointer
in such a case, and teach format_config() to react to the condition
by returning 1 (which is different from 0 that is a normal success
and negative that is an error) to its callers. Adjust the callers
to react to this new return value that tells them to pretend as if
they did not even see this partcular <key, value> pair.

Sometimes people want to specify additional configuration data
as "best effort" basis. Maybe commit.template configuration file points
at somewhere in ~/template/ but on a particular system, the file may not
exist and the user may be OK without using the template in such a case.
When the value given to a configuration variable whose type is
pathname wants to signal such an optional file, it can be marked by
prepending ":(optional)" in front of it. Such a setting that is
marked optional would avoid getting the command barf for a missing
file, as an optional configuration setting that names a missing
file is not even seen.

"core.commentChar=auto" that attempts to dynamically pick a
suitable comment character is non-workable, as it is too much
trouble to support for little benefit, and is marked as deprecated.
* pw/3.0-commentchar-auto-deprecation:
commit: print advice when core.commentString=auto
config: warn on core.commentString=auto
breaking-changes: deprecate support for core.commentString=auto
|
|
Add some advice on how to change the config settings when
"core.commentString=auto" or "core.commentChar=auto". The advice
includes instructions for clearing the config setting or setting a
fixed comment string. To try and be as specific as possible, the advice
is customized based on the user's config. If "core.commentString=auto"
is set in the system config and the user does not have write
access then the advice omits the instructions to clear the config
and recommends changing the global config instead. An alternative
approach would be to advise the user to run "git config --show-origin"
and leave them to figure out how to fix it themselves but that seems
rather unfriendly. As we're forcing them to update their config we
should try and make that as easy as possible.
In order to generate this advice we need to record each file where
either of the config keys is set and whether a key occurs more that
once in a given file. This lets us generate the list of commands to
remove all the keys and also tells us which key the "auto" setting
comes from.
As we want the user to update their config we do not provide a way
for this advice to be disabled other than changing the value of
"core.commentChar" or "core.commentString".

As support for this setting was deprecated in the last commit print a
warning (or die when WITH_BREAKING_CHANGES is enabled) if it is set.
Avoid bombarding the user with warnings by only printing it (a) when
running commands that call "git commit" and (b) only once per command.
Some scaffolding is added to repo_read_config() to allow it to
detect deprecated config settings and warn about them. As both
"core.commentChar" and "core.commentString" set the comment
character we record which one of them is used and tailor the
warning message appropriately.
Note the odd combination of die_message() followed by die(NULL)
is to allow the next commit to insert a call to advise() in the middle.

When parsing an old-style GIT_CONFIG_PARAMETERS environment
variable, the code parses key=value pairs by splitting them at '='
into an array of strbuf's. As strbuf_split() leaves the delimiter
at the end of the split piece, the code has to manually trim it.
If we split with string_list_split(), that becomes unnecessary.
Retire the use of strbuf_split() from this code path.
Note that the max parameter of string_list_split() is of
an ergonomically iffy design---it specifies the maximum number of
times the function is allowed to split, which means that in order to
split a text into up to 2 pieces, you have to pass 1, not 2.

There are a couple of -Wsign-compare warnings in "config.c":
- `prepare_include_condition_pattern()` is returns a signed integer,
where it either returns a negative error code or the index of the
last dir separator in a path. That index will always be a
non-negative number, but we cannot just change the return type to a
`size_t` due to it being re-used as error code. This is fixed by
splitting up concerns: the return value is only used as error code,
and the prefix is now returned via an out-pointer. This fixes a sign
comparison warning when comparing `text.len < prefix`,
- We treat `struct config_store_data::seen` as signed integer in
several places even though it's unsigned.
- There are multiple trivial sign comparison warnings where we use a
signed loop index to iterate through an unsigned number of items.
Fix all of these issues and drop the `DISABLE_SIGN_COMPARE_WARNINGS`
macro.

In "config.c" we host both the business logic to read and write config
files as well as the logic to parse specific Git-related variables. On
the one hand this is mixing concerns, but even more importantly it means
that we cannot easily remove the dependency on `the_repository` in our
config parsing logic.
Move the logic into "environment.c". This file is a grab bag of all
kinds of global state already, so it is quite a good fit. Furthermore,
it also hosts most of the global variables that we're parsing the config
values into, making this an even better fit.
Note that there is one hidden change: in `parse_fsync_components()` we
use an `int` to iterate through `ARRAY_SIZE(fsync_component_names)`. But
as -Wsign-compare warnings are enabled in this file this causes a
compiler warning. The issue is fixed by using a `size_t` instead.
This change allows us to drop the `USE_THE_REPOSITORY_VARIABLE`
declaration.

In 036876a1067 (config: hide functions using `the_repository` by
default, 2024-08-13) we have moved around a bunch of functions in the
config subsystem that depend on `the_repository`. Those function have
been converted into mere wrappers around their equivalent function that
takes in a repository as parameter, and the intent was that we'll
eventually remove those wrappers to make the dependency on the global
repository variable explicit at the callsite.
Follow through with that intent and remove `git_config_set()`. All
callsites are adjusted so that they use `repo_config_set(the_repository,
...)` instead. While some callsites might already have a repository
available, this mechanical conversion is the exact same as the current
situation and thus cannot cause any regression. Those sites should
eventually be cleaned up in a later patch series.

If conflict comments already use a comment character that isn't "#", and
core.commentChar is set "auto", Git will ignore these lines during the
scan using ignored_log_message_bytes() and pick a new comment character
based on the rest of the message. The newly chosen character may be
different from the one used in the conflict comments and therefore,
these are no longer treated as comments and end up in the final commit
message.
For example, during a rebase if the user previously set
core.commentChar=% and then encounters a conflict, conflict comments
like "% Conflicts:" are generated. If the user subsequently sets
core.commentChar=auto before running `rebase --continue`, Git parses the
"auto" setting and begins scanning. It first uses the existing
'comment_line_str' (which is '%') to detect and ignore conflict comments
via ignored_log_message_bytes().
Then, Git scans the rest of the message (excluding conflict comments),
sees that none of the remaining lines start with '#' and decides to set
comment_line_str to '#'. Since the final commit character differs from
the one used in the conflict comments, those lines are no longer
considered comments and get included in the final commit message.
Set 'comment_line_str' to '#' when core.commentChar is set to 'auto' to
reset any previously set value.
While this does not solve the issue of conflict comment inclusion and
the user visible behaviour stays tha same, it standardizes the behaviour
of the code by always resetting 'comment_line_str' to '#' when
core.commentChar=auto is parsed.
The patch text is based on Phillip Wood's message:
https://lore.kernel.org/git/9e96aaab-79a2-4632-94cd-d016d4a63b30@gmail.com/

As well as receiving the config key and value, config callbacks
also receive a "struct key_value_info" containing information about
the source of the key-value pair. Accessing the "path" field of
this struct from a callback passed to repo_config() results in a
use-after-free. This happens because repo_config() first populates a
configset by calling config_with_options() and then iterates over the
configset with the callback passed by the caller. When the configset
is constructed it takes a shallow copy of the "struct key_value_info"
for each config setting. This leads to the use-after-free as the
"path" member is freed before config_with_options() returns.
We could fix this by interning the "path" field as we do
for the "filename" field but the "path" field is not actually
needed. It is populated with a copy of the "path" field from "struct
config_source". That field was added in d14d42440d8 (config: disallow
relative include paths from blobs, 2014-02-19) to distinguish between
relative include directives in files and those in blobs. However,
since 1b8132d99d8 (i18n: config: unfold error messages marked for
translation, 2016-07-28) we can differentiate these by looking at the
"origin_type" field in "struct key_value_info". So let's remove the
"path" members from "struct config_source" and "struct key_value_info"
and instead use a combination of the "filename" and "origin_type"
fields to determine the absolute path of relative includes.

When reading the config, values that contain a trailing CRLF are
stripped. If the value itself has a trailing CR, the normal LF that
follows results in the CR being unintentionally stripped. This may lead
to unintended behavior due to the config value written being different
when it gets read.
One such issue involves a repository with a submodule path containing a
trailing CR. When the submodule gets initialized, the submodule is
cloned without being checked out and has "core.worktree" set to the
submodule path. The git-checkout(1) that gets spawned later reads the
"core.worktree" config value, but without the trailing CR, and
consequently attempts to checkout to a different path than intended.
If the repository contains a matching path that is a symlink, it is
possible for the submodule repository to be checked out in arbitrary
locations. This is extra bad when the symlink points to the submodule
hooks directory and the submodule repository contains an executable
"post-checkout" hook. Once the submodule repository checkout completes,
the "post-checkout" hook immediately executes.
To prevent mismatched config state due to misinterpreting a trailing CR,
wrap config values containing CR in double quotes when writing the
entry. This ensures a trailing CR is always separated for an LF and thus
prevented from getting stripped.
Note that this problem cannot be addressed by just quoting each CR with
"\r". The reading side of the config interprets only a few backslash
escapes, and "\r" is not among them. This fix is sufficient though
because it only affects the CR at the end of a line and any literal CR
in the interior is already preserved.

The "object-store-ll.h" header has been introduced to keep transitive
header dependendcies and compile times at bay. Now that we have created
a new "object-store.c" file though we can easily move the last remaining
additional bit of "object-store.h", the `odb_path_map`, out of the
header.
Do so. As the "object-store.h" header is now equivalent to its low-level
alternative we drop the latter and inline it into the former.

A handful of built-in command implementations have been rewritten

The "core.bigFileThreshold" setting is stored in a global variable and
populated via `git_default_core_config()`. This may cause issues in
the case where one is handling multiple different repositories in a
single process with different values for that config key, as we may or
may not see the correct value in that case. Furthermore, global state
blocks our path towards libification.
Refactor the code so that we instead store the value in `struct
repo_settings`, where the value is computed as-needed and cached.
Note that this change requires us to adapt one test in t1050 that
verifies that we die when parsing an invalid "core.bigFileThreshold"
value. The exercised Git command doesn't use the value at all, and thus
it won't hit the new code path that parses the value. This is addressed
by using git-hash-object(1) instead, which does read the value.

The `repo` value can be NULL if a builtin command is run outside
any repository. The current implementation of `repo_config()` will
fail if `repo` is NULL.
If the `repo` is NULL the `repo_config()` can ignore the repository
configuration but it should read the other configuration sources like
the system-side configuration instead of failing.
Teach the `repo_config()` to allow `repo` to be NULL by calling the
`read_very_early_config()` which read config but only enumerate system
and global settings.
This will be useful in the following commits.

The "core.hooksPath" setting is stored in a global variable and
populated via the `git_default_core_config`. This may cause issues in
the case where one is handling multiple different repositories in a
single process with different values for that config key, as we may or
may not see the correct value in that case. Furthermore, global state
blocks our path towards libification.
Refactor the code so that we instead store the value in `struct
repo_settings`. The value is computed as-needed and cached. The result
should be functionally the same as there aren't ever any code paths
where we'd execute hooks outside the context of a repository.
Note that this requires us to change the passed-in repository in the
`repo_git_path()` family of functions to be non-constant, as we call
`adjust_git_path()` there.

We include "compat/zlib.h" in "git-compat-util.h", which is
unnecessarily broad given that we only have a small handful of files
that use the zlib library. Move the header into "git-zlib.h" instead and
adapt users of zlib to include that header.
One exception is the reftable library, as we don't want to use the
Git-specific wrapper of zlib there, so we include "compat/zlib.h"
instead. Furthermore, we move the include into "reftable/system.h" so
that users of the library other than Git can wire up zlib themselves.

The variables `packed_git_window_size` and `packed_git_limit` are global
config variables used in the `packfile.c` file. Since it is only used in
this file, let's change it from being a global config variable to a
local variable for the subsystem.
With this, we rid `packfile.c` from all global variable usage and this
means we can also remove the `USE_THE_REPOSITORY_VARIABLE` guard from
the file.
