cURL was updated from v8.15.0 to v8.16.0, and the LLVM-based builds (but
strangely not the GCC-based builds) continuously greet me thusly:

make: *** [Makefile:2877: http-push.o] Error 1
The easiest way to shut up that compile error (which is legitimate,
seeing as the `CURLOPT_INFILESIZE` options expects a `long` parameter,
but `buffer->buf.len` refers to the `size_t` attribute of a `strbuf`)
would be to simply cast the parameter to a `long`.
However, there is a much better solution: To use the
`CURLOPT_INFILESIZE_LARGE` option instead, which was added in cURL
v7.11.0 (see https://curl.se/ch/7.11.0.html) and which Git _already_
uses in `curl_append_msgs_to_imap()`.
This fix was the motivation for renaming `xcurl_off_t()` to
`cast_size_t_to_curl_off_t()` and making it available more broadly,
which is the reason why it is used here, too.

At the same time, this function is renamed to conform better with the

Give the user a list of suggestions for what to do when they run a

The first order of action will be to check the breaking changes
document;[1] this short error message says nothing about why this
command is deprecated, and in any case going into any kind of detail
might overwhelm the user.
Then they can find out if this has been discussed on the mailing list.
Then users who e.g. are using git-whatchanged(1) can learn that this is
arguably a plug-in replacement:
git log <opts> --raw --no-merges
Finally they are invited to send an email to the mailing list.
Also drop the “please add” part in favor of just using the “refusing”

Also drop “Thanks” since it now would require a new paragraph.

git-whatchanged(1) is deprecated and you need to pass
`--i-still-use-this` in order to force it to work as before.
There are two affected users, or usages:
1. people who use the command in scripts; and
2. people who are used to using it interactively.
For (1) the replacement is straightforward.[1] But people in (2) might
like the name or be really used to typing it.[3]
An obvious first thought is to suggest aliasing `whatchanged` to the
git-log(1) equivalent.[1] But this doesn’t work and is awkward since you
cannot shadow builtins via aliases.
Now you are left in an uncomfortable limbo; your alias won’t work until
the command is removed for good.
Let’s lift this limitation by allowing *deprecated* builtins to be
shadowed by aliases.
The only observed demand for aliasing has been for git-whatchanged(1),
not for git-pack-redundant(1). But let’s be consistent and treat all
deprecated commands the same.

We are about to complicate the command handling by allowing *deprecated*
builtins to be shadowed by aliases. We need to organize the code in
order to facilitate that.[1]
The code in the `while(1)` speculatively adds commands to the list
before finding out if it’s an alias. Let’s instead move it inside
`handle_alias(...)`—where it conceptually belongs anyway—and in turn
only run this logic when we have found an alias.[2]
[1]: We will do that with an additional call to `handle_alias(1)` inside
the loop. *Not* moving this code leaves a blind spot; we will miss
alias looping crafted via deprecated builtin names

With 145 builtin commands (according to `git --list-cmds=builtins`),
users are probably not keeping on top of which ones (if any) are
deprecated.
Let’s expand the experimental `--list-cmds`[1] to allow users and

upcoming commit to implement `is_deprecated_command`.

The write_midx_internal() method uses gotos to jump to a cleanup section to
clear memory before returning 'result'. Since these jumps are more common
for error conditions, initialize 'result' to -1 and then only set it to 0
before returning with success. There are a couple places where we return
with success via a jump.
This has the added benefit that the method now returns -1 on error instead
of an inconsistent 1 or -1.

Remove the remaining signed comparison warnings in midx-write.c so that
they can be enforced as errors in the future. After the previous change,
the remaining errors are due to iterator variables named 'i'.
The strategy here involves defining the variable within the for loop
syntax to make sure we use the appropriate bitness for the loop
sentinel. This matters in at least one method where the variable was
compared to uint32_t in some loops and size_t in others.
While adjusting these loops, there were some where the loop boundary was
checking against a uint32_t value _plus one_. These were replaced with
non-strict comparisons, but also the value is checked to not be
UINT32_MAX. Since the value is the number of incremental multi-pack-
indexes, this is not a meaningful restriction. The new die() is about
defensive programming more than it being realistically possible.

midx-write.c has the DISABLE_SIGN_COMPARE_WARNINGS macro defined for a
few reasons, but the biggest one is the use of a signed
preferred_pack_idx member inside the write_midx_context struct. The code
currently uses -1 to indicate an unset preferred pack but pack int ids
are normally handled as uint32_t. There are also a few loops that search
for the preferred pack by name and those iterators will need updates to
uint32_t in the next change.
For now, replace the use of -1 with a 'NO_PREFERRED_PACK' macro and an
equality check. The macro stores the max value of a uint32_t, so we
cannot store a preferred pack that appears last in a list of 2^32 total
packs, but that's expected to be unreasonable already. Furthermore, with
this change we end up extending the range from 2^31 possible packs to
2^32-1.
There are some careful things to worry about with initializing the
preferred pack in the struct and using that value when searching for a
preferred pack that was already incorrect but accidentally working when
the index was initialized to zero.

The incremental mode of writing a multi-pack-index has a few extra
conditions that could lead to failure, but these are currently
short-ciruiting with 'return -1' instead of setting the method's
'result' variable and going to the cleanup tag.
Replace these returns with gotos to avoid memory issues when exiting
early due to error conditions.
Unfortunately, these error conditions are difficult to reproduce with
test cases, which is perhaps one reason why the memory loss was not

The fill_packs_from_midx() method was refactored in fcb2205b77 (midx:
implement support for writing incremental MIDX chains, 2024-08-06) to
allow for preferred packfiles and incremental multi-pack-indexes.
However, this led to some conditions that can cause improperly
initialized memory in the context's list of packfiles.
The conditions caring about the preferred pack name or the incremental
flag are currently necessary to load a packfile. But the context is
still being populated with pack_info structs based on the packfile array
for the existing multi-pack-index even if prepare_midx_pack() isn't
called.
Add a new test that breaks under --stress when compiled with
SANITIZE=address. The chosen number of 100 packfiles was selected to get
the --stress output to fail about 50% of the time, while 50 packfiles
could not get a failure in most --stress runs.
The test case is marked as EXPENSIVE not only because of the number of
packfiles it creates, but because some CI environments were reporting
errors during the test that I could not reproduce, specifically around
being unable to open the packfiles or their pack-indexes.
When it fails under SANITIZE=address, it provides the following error:
AddressSanitizer:DEADLYSIGNAL
=================================================================
==3263517==ERROR: AddressSanitizer: SEGV on unknown address 0x000000000027
==3263517==The signal is caused by a READ memory access.

#4 0x562d5d46fff6 in cmd_multi_pack_index builtin/multi-pack-index.c:305
...
This failure stack trace is disconnected from the real fix because the bad
pointers are accessed later when closing the packfiles from the context.
There are a few different aspects to this fix that are worth noting:
1. We return to the previous behavior of fill_packs_from_midx to not
rely on the incremental flag or existence of a preferred pack.
2. The behavior to scan all layers of an incremental midx is kept, so
this is not a full revert of the change.
3. We skip allocating more room in the pack_info array if the pack
fails prepare_midx_pack().
4. The method has always returned 0 for success and 1 for failure, but
the condition checking for error added a check for a negative result
for failure, so that is now updated.
5. The call to open_pack_index() is removed, but this is needed later
in the case of a preferred pack. That call is moved to immediately
before its result is needed (checking for the object count).

In addition to the regular trace information produced by
CURLOPT_VERBOSE, recent curl versions can enable or disable tracing of
specific subsystems using a call to curl_global_trace().
This level of detail may or may not be useful for us in Git as mere
users of libcurl, but there's one case where we need it for a test. In
t5564, we set up a socks proxy, access it with GIT_TRACE_CURL set, and
expect to find socks-related messages in the output. This test is broken
in the release candidates for libcurl 8.16, as those socks messages are
no longer produced in the trace.
The problem bisects to curl's commit ab5e0bfddc (pytest: add SOCKS tests
and scoring, 2025-07-21). There the socks messages were moved from
generic infof() messages to the component-specific CURL_TRC_CF() system.
And so we do not see them by default, but only if "socks" is enabled as
a logging component.
Teach Git's http code to accept a component list from the
environment and pass it into curl_global_trace(). We can then use
that in the test to enable the correct component.
It should be safe to do so unconditionally. In older versions of curl
which don't support this call, setting the environment variable is a
noop. Likewise, any versions of curl which don't recognize the "socks"
component should silently ignore it. The manpage for curl_global_trace()
says this:
The config string is a list of comma-separated component names. Names
are case-insensitive and unknown names are ignored. The special name
"all" applies to all components. Names may be prefixed with '+' or '-'
to enable or disable detailed logging for a component.
The list of component names is not part of curl's public API. Names may
be added or disappear in future versions of libcurl. Since unknown
names are silently ignored, outdated log configurations does not cause
errors when upgrading libcurl. Given that, some names can be expected
to be fairly stable and are listed below for easy reference.
So this should let us make the test work on all versions without
worrying about confusing older (or newer) versions. For the same reason,
I've opted not to document this interface. This is deep internal voodoo
for which we can make no promises to users. In fact, I was tempted to
simply hard-code "socks" to let our test pass and not expose anything.
But I suspect a little run-time flexibility may come in handy in the
future when debugging or dealing with similar logging issues.
I also considered just putting "all" into such a hard-coded default. But
if you try it, you will see that many of the components are quite
verbose and likely not interesting. They would clutter up our trace
output if we enabled them by default.

"make -JN" with INCLUDE_LIBGIT_RS enabled causes cargo lock warnings
and can trigger ld errors during the build.
The build errors are caused by two inner "make" invocations getting

Make libgit-rs depend on libgit-sys so that "make" prevents them

The compatibility object format is only implemented for loose objects,

addition, the underlying storage of loose object mapping is likely to
change because the current format is inefficient and does not handle
important mapping information such as that of submodules.
