Junio C Hamano 245cac5c33 remerge-diff: lazily prepare temporary objdir on demand
It is error prone for each caller that sets revs.remerge_diff bit
to be responsible for preparing a temporary object directory and
rotate it into the list of alternate object stores, making it the
primary object store.

Instead, remove the code to set up and arrange the temporary object
directory from the current callers and implement it in the code that
runs remerge-diff logic.  The code to undo the futzing of the list
of alternate object store is still spread across the callers, but we
will deal with it in future steps.

René Scharfe 0c4d5aa22d log-tree: use decimal_width()
Reduce code duplication by calling decimal_width() to count the digits
in the number of commits instead of calculating it locally.

It also has the advantage of returning int, which is the exact type
expected by the printf()-like function strbuf_addf() for field width
arguments.

Additionally, decimal_width() supports numbers bigger than 1410065407,
which is (hopefully) just a theoretical advantage.

Antonin Delpeuch 9c93ba4d0a merge-recursive: honor diff.algorithm
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.

Patrick Steinhardt e7da938570 global: introduce USE_THE_REPOSITORY_VARIABLE macro
Use of the `the_repository` variable is deprecated nowadays, and we
slowly but steadily convert the codebase to not use it anymore. Instead,
callers should be passing down the repository to work on via parameters.

It is hard though to prove that a given code unit does not use this
variable anymore. The most trivial case, merely demonstrating that there
is no direct use of `the_repository`, is already a bit of a pain during
code reviews as the reviewer needs to manually verify claims made by the
patch author. The bigger problem though is that we have many interfaces
that implicitly rely on `the_repository`.

Introduce a new `USE_THE_REPOSITORY_VARIABLE` macro that allows code
units to opt into usage of `the_repository`. The intent of this macro is
to demonstrate that a certain code unit does not use this variable
anymore, and to keep it from new dependencies on it in future changes,
be it explicit or implicit

For now, the macro only guards `the_repository` itself as well as
`the_hash_algo`. There are many more known interfaces where we have an
implicit dependency on `the_repository`, but those are not guarded at
the current point in time. Over time though, we should start to add
guards as required (or even better, just remove them).

Define the macro as required in our code units. As expected, most of our
code still relies on the global variable. Nearly all of our builtins
rely on the variable as there is no way yet to pass `the_repository` to
their entry point. For now, declare the macro in "biultin.h" to keep the
required changes at least a little bit more contained.

Patrick Steinhardt 44ec7c575f merge: fix leaking merge bases
When calling either the recursive or the ORT merge machineries we need
to provide a list of merge bases. The ownership of that parameter is
then implicitly transferred to the callee, which is somewhat fishy.
Furthermore, that list may leak in some cases where the merge machinery
runs into an error, thus causing a memory leak.

Refactor the code such that we stop transferring ownership. Instead, the
merge machinery will now create its own local copies of the passed in
list as required if they need to modify the list. Free the list at the
callsites as required.

Junio C Hamano 2fa04cebfb format-patch: move range/inter diff at the end of a single patch output
When running "format-patch" on a multiple patch series, the output
coming from "--interdiff" and "--range-diff" options is inserted
after the "shortlog" list of commits and the overall diffstat.

The idea is that shortlog/diffstat are shorter and with denser
information content, which gives a better overview before the
readers dive into more details of range/inter diff.

When working on a single patch, however, we stuff the inter/range
diff output before the actual patch, next to the diffstat.  This
pushes down the patch text way down with inter/range diff output,
distracting readers.

Move the inter/range diff output to the very end of the output,
after all the patch text is shown.

As the inter/range diff is no longer part of the commentary block
(i.e., what comes after the log message and "---", but before the
patch text), stop producing "---" in the function that generates
them.  But to separate it out visually (note: this is not needed
to help tools like "git apply" that pay attention to the hunk
headers to figure out the length of the hunks), add an extra blank
line between the end of the patch text and the inter/range diff.

Junio C Hamano 84ed505515 show_log: factor out interdiff/range-diff generation
The integration of "git range-diff" with "git format-patch" for a
single patch (i.e., not generating "range-diff" into the cover
letter) hooks into log-tree.c:show_log(), which is responsible for
writing the log message out and other stuff.  Essentially,
everything you see before the diffstat and the patch is generated
there.

Split out the code that spits out the interdiff/range-diff into a
separate helper function show_diff_of_diff().  Hopefully this will
make it easier to move things around in the output stream in the
future patches.

This is supposed to be a no-op refactoring.

René Scharfe 9720d23e8c date: make DATE_MODE thread-safe
date_mode_from_type() modifies a static variable and returns a pointer
to it.  This is not thread-safe.  Most callers of date_mode_from_type()
use it via the macro DATE_MODE and pass its result on to functions like
show_date(), which take a const pointer and don't modify the struct.

Avoid the static storage by putting the variable on the stack and
returning the whole struct date_mode.  Change functions that take a
constant pointer to expect the whole struct instead.

Reduce the cost of passing struct date_mode around on 64-bit systems
by reordering its members to close the hole between the 32-bit wide
.type and the 64-bit aligned .strftime_fmt as well as the alignment
hole at the end.  sizeof reports 24 before and 16 with this change
on x64.  Keep .type at the top to still allow initialization without
designator -- though that's only done in a single location, in
builtin/blame.c.

Jeff King 1c10b8e5b0 format-patch: fix leak of empty header string
The log_write_email_headers() function recently learned to return the
"extra_headers_p" variable to the caller as an allocated string. We
start by copying rev_info.extra_headers into a strbuf, and then detach
the strbuf at the end of the function. If there are no extra headers, we
leave the strbuf empty. Likewise, if there are no headers to return, we
pass back NULL.

This misses a corner case which can cause a leak. The "do we have any
headers to copy" check is done by looking for a NULL opt->extra_headers.
But the "do we have a non-empty string to return" check is done by
checking the length of the strbuf. That means if opt->extra_headers is
the empty string, we'll "copy" it into the strbuf, triggering an
allocation, but then leak the buffer when we return NULL from the
function.

We can solve this in one of two ways:

  1. Rather than checking headers->len at the end, we could check
     headers->alloc to see if we allocated anything. That retains the
     original behavior before the recent change, where an empty
     extra_headers string is "passed through" to the caller. In practice
     this doesn't matter, though (the code which eventually looks at the
     result treats NULL or the empty string the same).

  2. Only bother copying a non-empty string into the strbuf. This has
     the added bonus of avoiding a pointless allocation.

     Arguably strbuf_addstr() could do this optimization itself, though
     it may be slightly dangerous to do so (some existing callers may
     not get a fresh allocation when they expect to). In theory callers
     are all supposed to use strbuf_detach() in such a case, but there's
     no guarantee that this is the case.

This patch uses option 2. Without it, building with SANITIZE=leak shows
many errors in t4021 and elsewhere.

Jeff King 838ba014ce format-patch: simplify after-subject MIME header handling
In log_write_email_headers(), we append our MIME headers to the set of
extra headers by creating a new strbuf, adding the existing headers, and
then adding our new ones.  We had to do it this way when our output
buffer might point to the constant opt->extra_headers variable.

But since the previous commit, we always make a local copy of that
variable. Let's turn that into a strbuf, which lets the MIME code simply
append to it. That simplifies the function and avoids a pointless extra
copy of the headers.

Jeff King 305a68143c format-patch: return an allocated string from log_write_email_headers()
When pretty-printing a commit in the email format, we have to fill in
the "after subject" field of the pretty_print_context with any extra
headers the user provided (e.g., from "--to" or "--cc" options) plus any
special MIME headers.

We return an out-pointer that sometimes points to a newly heap-allocated
string and sometimes not. To avoid leaking, we store the allocated
version in a buffer with static lifetime, which is ugly. Worse, as we
extend the header feature, we'll end up having to repeat this ugly
pattern.

Instead, let's have our out-pointer pass ownership back to the caller,
and duplicate the string when necessary. This does mean one extra
allocation per commit when you use extra headers, but in the context of
format-patch which is showing diffs, I don't think that's even
measurable.

Jeff King 82363d9670 log: do not set up extra_headers for non-email formats
The commit pretty-printer code has an "after_subject" parameter which it
uses to insert extra headers into the email format. In show_log() we set
this by calling log_write_email_headers() if we are using an email
format, but otherwise default the variable to the rev_info.extra_headers
variable.

Since the pretty-printer code will ignore after_subject unless we are
using an email format, this default is pointless. We can just set
after_subject directly, eliminating an extra variable.

Jeff King d5a90d6319 pretty: drop print_email_subject flag
With one exception, the print_email_subject flag is set if and only if
the commit format is email based:

  - in make_cover_letter() we set it along with CMIT_FMT_EMAIL
    explicitly

  - in show_log(), we set it if cmit_fmt_is_mail() is true. That covers
    format-patch as well as "git log --format=email" (or mboxrd).

The one exception is "rev-list --format=email", which somewhat
nonsensically prints the author and date as email headers, but no
subject, like:

  $ git rev-list --format=email HEAD
  commit 64fc4c2cdd4db2645eaabb47aa4bac820b03cdba
  From: Jeff King <peff@peff.net>
  Date: Tue, 19 Mar 2024 19:39:26 -0400

  this is the subject

  this is the body

It's doubtful that this is a useful format at all (the "commit" lines
replace the "From" lines that would make it work as an actual mbox).
But I think that printing the subject as a header (like this patch does)
is the least surprising thing to do.

So let's drop this field, making the code a little simpler and easier to
reason about. Note that we do need to set the "rev" field of the
pretty_print_context in rev-list, since that is used to check for
subject_prefix, etc. It's not possible to set those fields via rev-list,
so we'll always just print "Subject: ". But unless we pass in our
rev_info, fmt_output_email_subject() would segfault trying to figure it
out.

(Makefile: add USE_WILDMATCH to use wildmatch as fnmatch, 2013-01-01) as
a way to be able to compile-time force any calls to fnmatch() to instead
invoke wildmatch().  The defines and inline function were removed in
70a8fc999d (stop using fnmatch (either native or compat), 2014-02-15),
and this include in git-compat-util.h has been unnecessary ever since.

Remove the include from git-compat-util.h, but add it to the .c files
that had omitted the direct #include they needed.

Derrick Stolee f1178380ac replace-objects: create wrapper around setting
The 'read_replace_objects' constant is initialized by git_default_config
(if core.useReplaceRefs is disabled) and within setup_git_env (if
GIT_NO_REPLACE_OBJECTS) is set. To ensure that this variable cannot be
set accidentally in other places, wrap it in a replace_refs_enabled()
method.

Since we still assign this global in config.c, we are not able to remove
the global scope of this variable and make it a static within
replace-object.c. This will happen in a later change which will also
prevent the variable from being read before it is initialized.

Centralizing read access to the variable is an important first step.

Junio C Hamano ba4324c4e1 e-mail workflow: Message-ID is spelled with ID in both capital letters
We used to write "Message-Id:" and "Message-ID:" pretty much
interchangeably, and the header name is defined to be case
insensitive by the RFCs, but the canonical form "Message-ID:" is
used throughout the RFC documents, so let's imitate it ourselves.
