Remove unused header "#include".
* en/header-cleanup:
treewide: remove unnecessary includes in source files
treewide: add direct includes currently only pulled in transitively
trace2/tr2_tls.h: remove unnecessary include
submodule-config.h: remove unnecessary include
pkt-line.h: remove unnecessary include
line-log.h: remove unnecessary include
http.h: remove unnecessary include
fsmonitor--daemon.h: remove unnecessary includes
blame.h: remove unnecessary includes
archive.h: remove unnecessary include
treewide: remove unnecessary includes in source files
treewide: remove unnecessary includes from header files
|
|
Each of these were checked with
gcc -E -I. ${SOURCE_FILE} | grep ${HEADER_FILE}
to ensure that removing the direct inclusion of the header actually
resulted in that header no longer being included at all (i.e. that
no other header pulled it in transitively).
...except for a few cases where we verified that although the header
was brought in transitively, nothing from it was directly used in
that source file. These cases were:
* builtin/credential-cache.c
* builtin/pull.c
* builtin/send-pack.c

Some codepaths did not correctly parse configuration variables
specified with valueless "true", which has been corrected.
* jk/implicit-true:
fsck: handle NULL value when parsing message config
trailer: handle NULL value when parsing trailer-specific config
submodule: handle NULL value when parsing submodule.*.branch
help: handle NULL value for alias.* config
trace2: handle NULL values in tr2_sysenv config callback
setup: handle NULL value when parsing extensions
config: handle NULL value when parsing non-bools
|

When the config parser sees an "implicit" bool like:
[core]
someVariable
it passes NULL to the config callback. Any callback code which expects a
string must check for NULL. This usually happens via helpers like
git_config_string(), etc, but some custom code forgets to do so and will
segfault.
These are all fairly vanilla cases where the solution is just the usual
pattern of:
if (!value)
return config_error_nonbool(var);
though note that in a few cases we have to split initializers like:
int some_var = initializer();
into:
int some_var;
if (!value)
return config_error_nonbool(var);
some_var = initializer();
There are still some broken instances after this patch, which I'll
address on their own in individual patches after this one.

When writing the cover letter, the encode_email_headers option was
ignored. That is, UTF-8 subject lines and email addresses were
written out as-is, without any Q-encoding, even if
--encode-email-headers was passed on the command line.
This is due to encode_email_headers not being copied over from
struct rev_info to struct pretty_print_context. Fix that and add
a test.

Extract the commonly used initialization of the --stat-width=<width>,
--stat-name-width=<width> and --stat-graph-with=<width> parameters to their
internal default values into a helper function, to avoid repeating the same
initialization code in a few places.
Add a couple of tests to additionally cover existing configuration options
diff.statNameWidth=<width> and diff.statGraphWidth=<width> when used by
git-merge to generate --stat outputs. This closes the gap that existed
previously in the --stat tests, and reduces the chances for having any
regressions introduced by this commit.
While there, perform a small bunch of minor wording tweaks in the improved
unit test, to improve its test-level consistency a bit.

Add new configuration option diff.statNameWidth=<width> that is equivalent
to the command-line option --stat-name-width=<width>, but it is ignored
by format-patch. This follows the logic established by the already
existing configuration option diff.statGraphWidth=<width>.
Limiting the widths of names and graphs in the --stat output makes sense
for interactive work on wide terminals with many columns, hence the support
for these configuration options. They don't affect format-patch because
it already adheres to the traditional 80-column standard.
Update the documentation and add more tests to cover new configuration
option diff.statNameWidth=<width>. While there, perform a few minor code
and whitespace cleanups here and there, as spotted.

The previous commit argued that parse-options callbacks should try to
use opt->value rather than touching globals directly. In some cases,
however, that's awkward to do. Some callbacks touch multiple variables,
or may even just call into an abstracted function that does so.
In some of these cases we _could_ convert them by stuffing the multiple
variables into a single struct and passing the struct pointer through
opt->value. But that may make other parts of the code less readable,
as the struct relationship has to be mentioned everywhere.
Let's just accept that these cases are special and leave them as-is. But
we do need to mark their "opt" parameters to satisfy -Wunused-parameter.

The to_callback() and cc_callback() functions are identical to the
generic parse_opt_string_list() function (except that they don't handle
optional arguments, but that's OK because their callers do not use the
OPTARG flag).

Rather than replacing the configured subject prefix (either through the
git config or command line) entirely with "RFC PATCH", this change
prepends RFC to whatever subject prefix was already in use.
This is useful, for example, when a user is working on a repository that
has a subject prefix considered to disambiguate patches:
git config format.subjectPrefix 'PATCH my-project'
Prior to this change, formatting patches with --rfc would lose the
'my-project' information.
The data flow for the subject-prefix was that rev.subject_prefix
were to be kept the authoritative version of the subject prefix even
while parsing command line options, and sprefix variable was used as
a temporary area to futz with it. Now, the parsing code has been
refactored to build the subject prefix into the sprefix variable and
assigns its value at the end to rev.subject_prefix, which makes the
flow easier to grasp.

Many programs use diff_result_code() to get a user-visible program exit
code from a diff result (e.g., checking opts.found_changes if
--exit-code was requested).
This function also takes a "status" parameter, which seems at first
glance that it could be used to propagate an error encountered when
computing the diff. But it doesn't work that way:
- negative values are passed through as-is, but are not appropriate as
program exit codes
- when --exit-code or --check is in effect, we _ignore_ the passed-in
status completely. So a failed diff which did not have a chance to
set opts.found_changes would erroneously report "success, no
changes" instead of propagating the error.
After recent cleanups, neither of these bugs is possible to trigger, as
every caller just passes in "0". So rather than fixing them, we can
simply drop the useless parameter instead.

This patch makes it possible to directly feed a branch description to
derive the cover letter from. The use case is formatting dynamically
created temporary commits which are not referenced anywhere.
The most obvious alternative would be creating a temporary branch and
setting a description on it, but that doesn't seem particularly elegant.

The setup_revision_opt struct has a "tweak" function pointer, which can
be used to adjust parameters after setup_revisions() parses arguments,
but before it finalizes setup. In addition to the rev_info struct, the
callback receives a pointer to the setup_revision_opt, as well.
But none of the existing callbacks looks at the extra "opt" parameter,
leading to -Wunused-parameter warnings.
We could mark it as UNUSED, but instead let's remove it entirely. It's
conceivable that it could be useful for a callback to have access to the
"opt" struct. But in the 13 years that this mechanism has existed,
nobody has used it. So let's just drop it in the name of simplifying.

Plumb "struct key_value_info" through all code paths that end in
die_bad_number(), which lets us remove the helper functions that read
analogous values from "struct config_reader". As a result, nothing reads
config_reader.config_kvi any more, so remove that too.
In config.c, this requires changing the signature of
git_configset_get_value() to 'return' "kvi" in an out parameter so that
git_configset_get_<type>() can pass it to git_config_<type>(). Only
numeric types will use "kvi", so for non-numeric types (e.g.
git_configset_get_string()), pass NULL to indicate that the out
parameter isn't needed.
Outside of config.c, config callbacks now need to pass "ctx->kvi" to any
of the git_config_<type>() functions that parse a config string into a
number type. Included is a .cocci patch to make that refactor.
The only exceptional case is builtin/config.c, where git_config_<type>()
is called outside of a config callback (namely, on user-provided input),
so config source information has never been available. In this case,
die_bad_number() defaults to a generic, but perfectly descriptive
message. Let's provide a safe, non-NULL for "kvi" anyway, but make sure
not to change the message.

Add a new "const struct config_context *ctx" arg to config_fn_t to hold
additional information about the config iteration operation.
config_context has a "struct key_value_info kvi" member that holds
metadata about the config source being read (e.g. what kind of config
source it is, the filename, etc). In this series, we're only interested
in .kvi, so we could have just used "struct key_value_info" as an arg,
but config_context makes it possible to add/adjust members in the future
without changing the config_fn_t signature. We could also consider other
ways of organizing the args (e.g. moving the config name and value into
config_context or key_value_info), but in my experiments, the
incremental benefit doesn't justify the added complexity (e.g. a
config_fn_t will sometimes invoke another config_fn_t but with a
different config value).
In subsequent commits, the .kvi member will replace the global "struct
config_reader" in config.c, making config iteration a global-free
operation. It requires much more work for the machinery to provide
meaningful values of .kvi, so for now, merely change the signature and
call sites, pass NULL as a placeholder value, and don't rely on the arg
in any meaningful way.
Most of the changes are performed by
contrib/coccinelle/config_fn_ctx.pending.cocci, which, for every
config_fn_t:
- Modifies the signature to accept "const struct config_context *ctx"
- Passes "ctx" to any inner config_fn_t, if needed
- Adds UNUSED attributes to "ctx", if needed
Most config_fn_t instances are easily identified by seeing if they are
called by the various config functions. Most of the remaining ones are
manually named in the .cocci patch. Manual cleanups are still needed,
but the majority of it is trivial; it's either adjusting config_fn_t
that the .cocci patch didn't catch, or adding forward declarations of
"struct config_context ctx" to make the signatures make sense.
The non-trivial changes are in cases where we are invoking a config_fn_t
outside of config machinery, and we now need to decide what value of
"ctx" to pass. These cases are:
- trace2/tr2_cfg.c:tr2_cfg_set_fl()
This is indirectly called by git_config_set() so that the trace2
machinery can notice the new config values and update its settings
using the tr2 config parsing function, i.e. tr2_cfg_cb().
- builtin/checkout.c:checkout_main()
This calls git_xmerge_config() as a shorthand for parsing a CLI arg.
This might be worth refactoring away in the future, since
git_xmerge_config() can call git_default_config(), which can do much
more than just parsing.
Handle them by creating a KVI_INIT macro that initializes "struct
key_value_info" to a reasonable default, and use that to construct the
"ctx" arg.

In --follow mode, we require exactly one pathspec. We check this
condition in two places:
- in diff_setup_done(), we complain if --follow is used with an
inapropriate pathspec
- in git-log's revision "tweak" function, we enable log.follow only if
the pathspec allows it

When we are showing multiple patches with format-patch, we have to
repeatedly overwrite the rev.message_id field. We take care to avoid
leaking the old value by either freeing it, or adding it to
ref_message_ids, a string list of ids to reference in subsequent
messages.
But unfortunately we do leak the value via that string list. We try
to clear the string list, courtesy of 89f45cf4eb (format-patch: don't
leak "extra_headers" or "ref_message_ids", 2022-04-13). But since it was
initialized as "nodup", the string list doesn't realize it owns the
strings, and it leaks them.
We have two options here:
1. Continue to init with "nodup", but then tweak the value of
ref_message_ids.strdup_strings just before clearing.
2. Init with "dup", but use "append_nodup" when transferring ownership
of strings to the list. Clearing just works.
I picked the second here, as I think it calls attention to the tricky
part (transferring ownership via the nodup call).
There's one other related fix we have to do, though. We also insert the
result of clean_message_id() into the list. This _sometimes_ allocates
and sometimes does not, depending on whether we have to remove cruft
from the end of the string. Let's teach it to consistently return an
allocated string, so that the caller knows it must be freed.
There's no new test here, as the leak can already be seen in t4014.44 (as
well as others in that script). We can't mark all of t4014 as leak-free,
though, as there are other unrelated leaks that it triggers.

We may allocate a message-id string via gen_message_id(), but we never
free it, causing a small leak. This can be demonstrated by running t9001
with a leak-checking build. The offending test is the one touched by
3ece9bf0f9 (send-email: clear the $message_id after validation,
2023-05-17), but the leak is much older than that. The test was simply
unlucky enough to trigger the leaking code path for the first time.
We can fix this by freeing the string at the end of the function. We can
also re-mark the test script as leak-free, effectively reverting
20bd08aefb (t9001: mark the script as no longer leak checker clean,
2023-05-17).

Fix numerous and mostly long-standing segfaults in consumers of
the *_config_*value_multi() API. As discussed in the preceding commit
an empty key in the config syntax yields a "NULL" string, which these
users would give to strcmp() (or similar), resulting in segfaults.
As this change shows, most users users of the *_config_*value_multi()
API didn't really want such an an unsafe and low-level API, let's give
them something with the safety of git_config_get_string() instead.
This fix is similar to what the *_string() functions and others
acquired in[1] and [2]. Namely introducing and using a safer
"*_get_string_multi()" variant of the low-level "_*value_multi()"
function.
This fixes segfaults in code introduced in:
- d811c8e17c6 (versionsort: support reorder prerelease suffixes, 2015-02-26)
- c026557a373 (versioncmp: generalize version sort suffix reordering, 2016-12-08)

- 50a044f1e40 (gc: replace config subprocesses with API calls, 2022-09-27)
There are now two users ofthe low-level API:
- One in "builtin/for-each-repo.c", which we'll convert in a
subsequent commit.
- The "t/helper/test-config.c" code added in [3].
As seen in the preceding commit we need to give the
"t/helper/test-config.c" caller these "NULL" entries.
We could also alter the underlying git_configset_get_value_multi()
function to be "string safe", but doing so would leave no room for
other variants of "*_get_value_multi()" that coerce to other types.
Such coercion can't be built on the string version, since as we've
established "NULL" is a true value in the boolean context, but if we
coerced it to "" for use in a list of strings it'll be subsequently
coerced to "false" as a boolean.
The callback pattern being used here will make it easy to introduce
e.g. a "multi" variant which coerces its values to "bool", "int",
"path" etc.

Have the "git_configset_get_value_multi()" function and its siblings
return an "int" and populate a "**dest" parameter like every other
git_configset_get_*()" in the API.
As we'll take advantage of in subsequent commits, this fixes a blind
spot in the API where it wasn't possible to tell whether a list was
empty from whether a config key existed. For now we don't make use of
those new return values, but faithfully convert existing API users.
Most of this is straightforward, commentary on cases that stand out:
- To ensure that we'll properly use the return values of this function
in the future we're using the "RESULT_MUST_BE_USED" macro introduced
in [1].
As git_die_config() now has to handle this return value let's have
it BUG() if it can't find the config entry. As tested for in a
preceding commit we can rely on getting the config list in
git_die_config().
- The loops after getting the "list" value in "builtin/gc.c" could
also make use of "unsorted_string_list_has_string()" instead of using
that loop, but let's leave that for now.
- In "versioncmp.c" we now use the return value of the functions,
instead of checking if the lists are still non-NULL.

"git format-patch" honors the src/dst prefixes set to nonstandard
values with configuration variables like "diff.noprefix", causing
receiving end of the patch that expects the standard -p1 format to
break. Teach "format-patch" to ignore end-user configuration and
always use the standard prefixes.
This is a backward compatibility breaking change.
* jk/format-patch-ignore-noprefix:
rebase: prefer --default-prefix to --{src,dst}-prefix for format-patch
format-patch: add format.noprefix option
format-patch: do not respect diff.noprefix
diff: add --default-prefix option
t4013: add tests for diff prefix options
diff: factor out src/dst prefix setup
