strbuf_attach: fix call sites to pass correct alloc
strbuf: pass correct alloc to strbuf_attach() in strbuf_reencode()
|
|
strbuf_attach(sb, buf, len, alloc) requires alloc > len (the buffer
must have at least len+1 bytes to hold the NUL). Several call sites
passed alloc == len, relying on strbuf_grow(sb, 0) inside strbuf_attach
to reallocate. Fix these in mailinfo, am, refs/files-backend,
fast-import, and trailer by passing len+1 when the buffer is a
NUL-terminated string (or from strbuf_detach).

The prepare_auto_maintenance() relies on the_repository to read
configurations. Since run_auto_maintenance() calls
prepare_auto_maintenance(), it also implicitly depends the_repository.
Add 'struct repository *' as a parameter to both functions and update
all callers to pass the_repository.
With no global repository dependencies left in this file, remove the
USE_THE_REPOSITORY_VARIABLE macro.

Rename three functions around the commit_list data structure.
* ps/commit-list-functions-renamed:
commit: rename `free_commit_list()` to conform to coding guidelines
commit: rename `reverse_commit_list()` to conform to coding guidelines
commit: rename `copy_commit_list()` to conform to coding guidelines
|
|
Our coding guidelines say that:
Functions that operate on `struct S` are named `S_<verb>()` and should
generally receive a pointer to `struct S` as first parameter.
While most of the functions related to `struct commit_list` already
follow that naming schema, `free_commit_list()` doesn't.
Rename the function to address this and adjust all of its callers. Add a
compatibility wrapper for the old function name to ease the transition
and avoid any semantic conflicts with in-flight patch series. This
wrapper will be removed once Git 2.53 has been released.

to allow the functions that implicitly use the_repository to be retired

Long ago Git's decision to show color for a subsytem was stored in a
tri-state variable: it could be true (1), false (0), or unknown (-1).
But since daa0c3d971 (color: delay auto-color decision until point of
use, 2011-08-17) we want to carry around a new state, "auto", which
bases the decision on the tty-ness of stdout (rather than collapsing
that "auto" state to a true/false immediately).
That commit introduced a set of GIT_COLOR_* defines to represent each
state: UNKNOWN, ALWAYS, NEVER, and AUTO. But it only used the AUTO
value, and left alone code using bare 0/1/-1 values. And of course since
then we've grown many new spots that use those bare values.
Let's switch all of these to use the named constants. That should make
the code a bit easier to read, as it is more obvious that we're
representing a color decision.

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_get_bool()`. All
callsites are adjusted so that they use
`repo_config_get_bool(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.

Sometimes code wants to die in a situation where it already has written
an error message. To use the same error code as `die()` we have to use
`exit(128)`, which is easy to get wrong and leaves magic numbers all
over our codebase.
Teach `die_message_builtin()` to not print any error when passed a
`NULL` pointer as error string. Like this, such users can now call
`die(NULL)` to achieve the same result without any hardcoded error
codes.
Adapt a couple of builtins to use this new pattern to demonstrate that
there is a need for such a helper.

While we expose macros for most of our different option types understood
by the "parse-options" subsystem, not every combination of fields that
has one as that would otherwise quickly lead to an explosion of macros.
Instead, we just initialize structures manually for those variants of
fields that don't have a macro.
Callsites that open-code these structure initialization don't use
designated initializers though and instead just provide values for each
of the fields that they want to initialize. This has three significant
downsides:
- Callsites need to specify all values up to the last field that they
care about. This often includes fields that should simply be left at
their default zero-initialized state, which adds distraction.
- Any reader not deeply familiar with the layout of the structure
has a hard time figuring out what the respective initializers mean.
- Reordering or introducing new fields in the middle of the structure
is impossible without adapting all callsites.
Convert all sites to instead use designated initializers, which we have
started using in our codebase quite a while ago. This allows us to skip
any default-initialized fields, gives the reader context by specifying
the field names and allows us to reorder or introduce new fields where
we want to.

Switch from merge-recursive to merge-ort. Adjust the following
testcases due to the switch:
* t4151: This test left an untracked file in the way of the merge.
merge-recursive could only sometimes tell when untracked files were
in the way, and by the time it discovers others, it has already made
too many changes to back out of the merge. So, instead of writing the
results to e.g. 'file1' it would instead write them to
'file1~branch1'. This is confusing for users, because they might not
notice 'file1~branch1' and accidentally add and commit 'file1'.
In contrast, merge-ort correctly notices the file in the way before
making any changes and aborts. Since this test didn't care about the
file in the way, just remove it before calling git-am.
* t4255: Usage of merge-ort allows us to change two known failures into
successes.
* t6427: As noted a few commits ago, the choice of conflict label for
diff3 markers for the ancestor commit was previously handled by
merge-recursive.c rather than by callers. Since that has now changed,
`git am` needs to specify that label. Although the previous conflict
label ("constructed merge base") was already fairly somewhat slanted
towards `git am`, let's use wording more along the lines of the
related command-line flag from `git apply` and function involved to
tie it more closely to `git am`.

The test in t7600 for "git merge -h" may want to be retired, as the
same is covered by t0012 already, but it is specifically testing that
the "-h" option gets a response even with a corrupt index file, so
for now let's leave it there.

The `struct diff_flags` structure is essentially an array of flags, all
of which have the same type. We can thus use `sizeof()` to iterate
through all of the flags, which we do in `diff_flags_or()`. But while
the statement returns an unsigned integer, we used a signed integer to
iterate through the flags, which generates a warning.

The documentation claims that "recursive defaults to the diff.algorithm
config setting", but this is currently not the case. This fixes it,
ensuring that diff.algorithm is used when -Xdiff-algorithm is not
supplied. This affects the following porcelain commands: "merge",
"rebase", "cherry-pick", "pull", "stash", "log", "am" and "checkout".
It also affects the "merge-tree" ancillary interrogator.
This change refactors the initialization of merge options to introduce
two functions, "init_merge_ui_options" and "init_merge_basic_options"
instead of just one "init_merge_options". This design follows the
approach used in diff.c, providing initialization methods for
porcelain and plumbing commands respectively. Thanks to that, the
"replay" and "merge-recursive" plumbing commands remain unaffected by
diff.algorithm.

When creating commits via `commit_tree_extended()`, the caller passes in
a string list of parents. This call implicitly transfers ownership of
that list to the function, which is quite surprising to begin with. But
to make matters worse, `commit_tree_extended()` doesn't even bother to
free the list of parents in error cases. The result is a memory leak,
and one that the caller cannot fix by themselves because they do not
know whether parts of the string list have already been released.
Refactor the code such that callers can keep ownership of the list of
parents, which is getting indicated by parameter being a constant
pointer now. Free the lists at the calling site and add a common exit
path to those sites as required.

In `cmd_merge_recursive()` we have a static array of object ID bases
that we pass to `merge_recursive_generic()`. This interface is somewhat
weird though because the latter function accepts a pointer to a pointer
of object IDs, which requires us to allocate the object IDs on the heap.
And as we never free those object IDs, the end result is a leak.
While we can easily solve this leak by just freeing the respective
object IDs, the whole calling convention is somewhat weird. Instead,
refactor `merge_recursive_generic()` to accept a plain pointer to object
IDs so that we can avoid allocating them altogether.

After a patch fails, you can ask "git am" to try applying it again with
new options by running without any of the resume options. E.g.:
git am <patch
# oops, it failed; let's try again
git am --3way
But since this second command has no explicit resume option (like
"--continue"), it looks just like an invocation to read a fresh patch
from stdin. To avoid confusing the two cases, there are some heuristics,
courtesy of 8d18550318 (builtin-am: reject patches when there's a
session in progress, 2015-08-04):
if (in_progress) {
/*
* Catch user error to feed us patches when there is a session
* in progress:
*
* 1. mbox path(s) are provided on the command-line.
* 2. stdin is not a tty: the user is trying to feed us a patch
* from standard input. This is somewhat unreliable -- stdin
* could be /dev/null for example and the caller did not
* intend to feed us a patch but wanted to continue
* unattended.
*/
if (argc || (resume_mode == RESUME_FALSE && !isatty(0)))
die(_("previous rebase directory %s still exists but mbox given."),
state.dir);
if (resume_mode == RESUME_FALSE)
resume_mode = RESUME_APPLY;
[...]
So if no resume command is given, then we require that stdin be a tty,
and otherwise complain about (potentially) receiving an mbox on stdin.
But of course you might not actually have a terminal available! And
sadly there is no explicit way to hit this same code path; this is the
only place that sets RESUME_APPLY. So you're stuck, and scripts like our
test suite have to bend over backwards to create a pseudo-tty.
Let's provide an explicit option to trigger this mode. The code turns
out to be quite simple; just setting "resume_mode" to RESUME_FALSE is
enough to dodge the tty check, and then our state is the same as it
would be with the heuristic case (which we'll continue to allow).
When we don't have a session in progress, there's already code to
complain when resume_mode is set (but we'll add a new test to cover
that).
To test the new option, we'll convert the existing tests that rely on
the fake stdin tty. That lets us test them on more platforms, and will
let us simplify test_terminal a bit in a future patch.
It does, however, mean we're not testing the tty heuristic at all.

stderr to 'err', since this is less confusing. In t4254, as we are
testing a specific failure mode of 'git am', simply disable the advice.
Note that we are not testing that this advice is shown in 'git rebase'
for the apply backend since 2ac0d6273f (rebase: change the default
backend from "am" to "merge", 2020-02-15).

As part of our transition to multi-byte comment characters, let's take a
NUL-terminated string pointer for strbuf_stripspace(), rather than a
single character. We can continue to support its feature of ignoring
comments by accepting a NULL pointer (as opposed to the current behavior
of a NUL byte).
All of the callers have to be adjusted, but they can all just pass
comment_line_str (or NULL).
Inside the function we detect comments by comparing the first byte of a
line to the comment character. We'll adjust that to use starts_with(),
which will match multiple bytes (though for now, of course, we still
only allow a single byte, so it's academic).

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

Doc and help update.
* rs/fix-arghelp:
am, rebase: fix arghelp syntax of --empty
|
|
Use parentheses and pipes to present alternatives in the argument help
for the --empty options of git am and git rebase, like in the rest of
the documentation.
While at it remove a stray use of the enum empty_action value
STOP_ON_EMPTY_COMMIT to indicate that no short option is present.
While it has a value of 0 and thus there is no user-visible change,
that enum is not meant to hold short option characters. Hard-code 0,
like we do for other options without a short option.

Let the parse-options code detect and handle the use of options that are
incompatible with --show-current-patch. This requires exposing the
distinction between the "raw" and "diff" sub-modes. Do that by
splitting the mode RESUME_SHOW_PATCH into RESUME_SHOW_PATCH_RAW and
RESUME_SHOW_PATCH_DIFF and stop tracking sub-modes in a separate struct.
The result is a simpler callback function and more precise error
messages. The original reports a spurious argument or a NULL pointer:
$ git am --show-current-patch --show-current-patch=diff
error: options '--show-current-patch=diff' and '--show-current-patch=raw' cannot be used together
$ git am --show-current-patch=diff --show-current-patch
error: options '--show-current-patch=(null)' and '--show-current-patch=diff' cannot be used together
With this patch we get the more precise:
$ git am --show-current-patch --show-current-patch=diff
error: --show-current-patch=diff is incompatible with --show-current-patch
$ git am --show-current-patch=diff --show-current-patch
error: --show-current-patch is incompatible with --show-current-patch=diff

To make it possible for git ls-tree to display the tree encoded
in the hash algorithm of the oid specified to git ls-tree, update
init_tree_desc to take as a parameter the oid of the tree object.
Update all callers of init_tree_desc and init_tree_desc_gently
to pass the oid of the tree object.
Use the oid of the tree object to discover the hash algorithm
of the oid and store that hash algorithm in struct tree_desc.
Use the hash algorithm in decode_tree_entry and
update_tree_entry_internal to handle reading a tree object encoded in
a hash algorithm that differs from the repositories hash algorithm.
