[PATCH 0/5] slimming down installed size

[PATCH 0/5] slimming down installed size

[Jeff King]

A while ago I was looking at the size of an installed (and stripped)
build of Git, and noticed we could make a few more things into builtins.

Patches 2-4 do that.  I don't think there's any real downside here.
We're not bringing in any new link dependencies to the main binary. And
even if these programs don't use all of the code that's in the main
binary, operating systems are good at just loading the pages that we do
need (and you're probably running other Git programs anyway, which means
the main binary is in RAM anyway and we're actually reducing the overall
memory footprint).

The final patch is not strictly related, but it's something I've had
sitting around for a long time. I actually posted it almost exactly two
years ago:

  https://lore.kernel.org/git/20180817190310.GA5360@sigill.intra.peff.net/

which ended with Jonathan saying:

>  - keeping this in-tree for the benefit of just one user is excessive,
>    so removing it is probably the right thing
> 
>  - it would be nice if the commit removing this code from Git includes
>    a note to help people find its new home
> 
> Would you mind holding off until I'm able to arrange that last bit?

So...I held off for a bit, but I'd really like to be done with this (and
I prefer dropping the code, because I have a few other tree-wide
cleanups for which I'd just as soon not have to deal with vcs-svn).

[PATCH 1/5] Makefile: drop builtins from MSVC pdb list

[Jeff King]

Over the years some more programs have become builtins, but nobody
updated this MSVC-specific section of the file (which specifically says
that it should not include builtins). Let's bring it up to date.

Signed-off-by: Jeff King <peff@peff.net>
---
Given that nobody has mentioned this, it makes me wonder if anybody is
even using this part of the Makefile at all these days. Or maybe having
extra lines here isn't a problem (though it's also missing some entries,
like one for git-bugreport).

If having extra entries didn't cause a problem, I would suspect that it
was just that. But that missing entries *also* doesn't cause a problem,
I'd suspect that this section of the Makefile just isn't being used.

Of course, I'm not using it since I'm not on Windows, but maybe dscho or
Stolee would know if there are legitimate uses. Of course, if there
aren't, I'm favor of getting rid of this section entirely.

I cc'd Jeff Hostetler, who added it. :)

I'm also pretty not-knowledgeable about Windows, but I think that
anybody using MSVC would do so through Visual Studio these days. And
that's being covered with recent cmake stuff. Or maybe I'm just
clueless. We'll see.

We create PDBs for our microsoft/git installers, such as in this
recent build: [1]

[1] https://dev.azure.com/gvfs/ci/_build/results?buildId=18994&view=artifacts&type=publishedArtifacts

Unzipping, I see PDBs for the git-* files listed in this command,
minus the ones that don't exist. So if this line is what creates
the PDBs, then it is not erroring out when trying to create the
PDBs for commands that don't exist.

Thanks,

Ah, thanks for the explanation. The good news is that this list should
be up to date after my series. ;)

We have a couple ways to build Git on Windows:

- the standard way, in a Git for Windows SDK (which is a slightly modified
  subset of MSYS2). This uses GCC and GNU make and all the things that you
  might suspect given Git's origins on Linux.

- the Visual Studio way, after running `make vcxproj` in Git for Windows'
  SDK. As part of the `vcxproj` target, the non-C parts of Git are
  generated and committed.

- the "new" Visual Studio way, after running CMake. The non-C parts are
  generated through CMake, which is nice because no Git for Windows SDK is
  required to build this from start to finish.

- the Visual C way, as championed by Jeff (and which was a prerequisite to
  working on the `vcxproj` target): in a Git for Windows SDK, use GNU make
  but replace GCC by MSVC (via the command-line): `make MSVC=1`.

While all four methods work, the only one that is regularly used with the
`make install` command is the first one.

The location you modified is in the `MSVC` part of `compat.mak.uname`,
i.e. in the Visual C part.

We originally had a tentative plan to eventually, maybe, build Git for
Windows using Visual C by default. However, it turned out that the
standard malloc in Visual C's runtime was tuned for other workloads than
Gits, and that nedmalloc performed better, and we originally could not get
nedmalloc to compile with a modern Visual C, so we stopped that effort.

That's why you still have support for `make MSVC=1 install`.

Since it seems not to be too much trouble, I would prefer to keep it
working for now, even if it is rarely exercised and regressions might
creep in (like the ones you fixed).

Thanks,
Dscho

Ah, thanks. That perfectly explains what is going on and why it might
not have been noticed. I agree it is not too much trouble to keep it
around for now.

Incidentally, I stumbled across the patch I carry in Git for Windows'
branch thicket that _actually_ fixes this. Will send it out in a couple
minutes.

On Windows, I always use either "make" or "make MSVC=1" from a SDK
shell window to build and test.  This lets me debug in either GDB or
Visual Studio directly against the EXE.  (That is, without any of the
project complications in the debugger or the artificial commits created
for the .vcxproj files.)  MSVC builds are built from source all the way 
down (including third-party libraries) thanks to vcpkg.

However, I never install my "make MSVC=1" builds, so I don't care about
the PDBs being redistributed.  As @dscho said, we added that thinking
that we would be able to do MSVC-based releases one day, but that ship
sank.

There were some very-early GVFS users who we (personally) gave MSVC-
based builds to help get stack traces via internal Watson channels,
but that is unnecessary now.

[PATCH 2/5] make credential helpers builtins

[Jeff King]

There's no real reason for credential helpers to be separate binaries. I
did them this way originally under the notion that helper don't _need_
to be part of Git, and so can be built totally separately (and indeed,
the ones in contrib/credential are). But the ones in our main Makefile
build on libgit.a, and the resulting binaries are reasonably large.

We can slim down our total disk footprint by just making them builtins.
This reduces the size of:

  make strip install

from 29MB to 24MB on my Debian system.

Note that credential-cache can't operate without support for Unix
sockets. Currently we just don't build it at all when NO_UNIX_SOCKETS is
set. We could continue that with conditionals in the Makefile and our
list of builtins. But instead, let's build a dummy implementation that
dies with an informative message. That has two advantages:

  - it's simpler, because the conditional bits are all kept inside
    the credential-cache source

  - a user who is expecting it to exist will be told _why_ they can't
    use it, rather than getting the "credential-cache is not a git
    command" error which makes it look like the Git install is broken.

Note that our dummy implementation does still respond to "-h" in order
to appease t0012 (and this may be a little friendlier for users, as
well).

Could you clarify which helpers you mean here? Git's own
credential-cache and store make sense to convert, but the helpers in
contrib definitely don't.

For what it's worth, I'm almost positive that you mean the in-tree
helpers (where in-tree means "in git.git but not in contrib"), in which
case I'm in favor of this direcftion.

Yep, that makes sense and I think this approach seems fine.

Yes, I mean the helpers in the Makefile that we build and install by

Makes sense, especially because none of the in-tree ones need to
link with any extra dependency at runtime, we do not even have to
debate if dynamic linkage overhead still matters ;-)

[PATCH 3/5] make git-bugreport a builtin

[Jeff King]

There's no reason that bugreport has to be a separate binary. And since
it links against libgit.a, it has a rather large disk footprint. Let's
make it a builtin, which reduces the size of a stripped installation
from 24MB to 22MB.

This also simplifies our Makefile a bit. And we can take advantage of
builtin niceties like RUN_SETUP_GENTLY.

I agree that this is a good change. I'm a bit surprised that a
feature added so recently wasn't added as a builtin in the first
place. Perhaps that was a conscious decision? Maybe it was just
because there was some point in time where it might have been
relegated to contrib.

I looked in the history for any rationale, but couldn't find any. There
is some discussion in the list, though. It looks like we moved from a
builtin to standalone between v3 and v4 of the series, due to this
sub-thread:

  https://lore.kernel.org/git/xmqqr2284is5.fsf@gitster-ct.c.googlers.com/

My take is:

  - I agree with Johannes that in terms of resource usage, builtins are
    better. I'm skeptical that extra code within the Git binary produces
    a meaningful impact on running other builtins (but I'd be happy to
    look at evidence if somebody has it).

  - Adding shared-library dependencies definitely _does_ impact other
    builtin commands. And I think last November when the series was
    shaping up that it wasn't clear if we might link to system-specific
    data gathering libraries. But that wasn't how the series shook out;
    we gather very little general system info, and we do it with basic
    and lightweight techniques (like uname, or compiler preprocessor
    macros). That could change eventually of course, but it's not like
    switching back to a stand-alone at that point is a big deal.

If it is not a big deal, then I am fine, but at the same time it
becomes unclear why we can say "we can use X and Y niceties only
available for builtins".

Actually, there is another issue that is potentially a lot worse.

"git bugreport" not being built-in would mean that the compiled-in
git-version MUST not be relied upon (it merely is a version of the
source "git bugreport" came from, it does not necessarily match the
main "git" binary when we are dealing with a confused user with
GIT_EXEC_PATH problem), but has to be asked to "git" binary on the
$PATH externally.  That needs to be done for any non-builtin
binaries (e.g. when user is having issue with git-remote--curl")
anyway, keeping "git bugreport" out of builtin would force us the
necessary discipline from early on.

I'm skeptical that an external program would help at all there. If you
say "git bugreport" you are going to get the "git" on your PATH. If it's
a builtin, then obviously we'd run that version. If it's not, then it
would run the first one from GIT_EXEC_PATH. That would normally be the
matching version. If there's a misconfiguration where that is not true,
then I'd argue the builtin version is likely to produce a better
response anyway.

If there were some mechanism by which that caused a failure that we
might notice and correct, I'd agree with your "necessary discipline"
comment. But in practice I think that:

  - it will either not matter for the details collected in the bug
    report, in which case nobody will notice the misconfiguration anyway

  - it will lead to confusing details in the report, at which point
    people will work manually with the submitter to figure out what is
    going on (just like they do now)

But I don't see a way that it systematically identifies such
misconfigurations or helps us avoid them. If it is a type of issue that
comes up a lot, then that's something the tool ought to be examining
systematically (looking at GIT* in the environment, reporting the
baked-in exec path, etc). Trying to glean that from behavior differences
in an external bugreport program sounds fragile and confusing.

Since `git bugreport` requires specific functionality from, say,
`git-remote--curl` we would already have a bit of trouble in case of
version skew there.

But yes, I am glad that we finally can at least rely on the Git version
`git bugreport` reports.

I may have oversold those niceties in the commit message. It is really
only saving us two lines of code, and it wouldn't be a big deal to
revert it (in fact, if you're uncomfortable with that, we could leave
the function otherwise intact).

I am on the fence, as bugreport does not seem to be fully completed
part of the system.  The original thinking was that it may soon want
to grow by linking with platform specific libraries for lower-level
system characteristic identification, at which time we'd not want to
have it in builtins and "we can take advantage of builtin niceties"
will cause us regrets.  The only reason that hasn't happened as far
as I can see is because its development speed is rather slow.

So, I dunno.

No, I think the reason is much more benign: my suggestion to query
information from the respective executables that _already_ link to said
shared libraries seems to have born fruit. It has the additional advantage
that we need not worry about cases where `git-bugreport` would look at a
different dependency than, say, `git-remote--curl`.

So yes, I am rather delighted that `bugreport` finally takes this
direction. It makes me much less worried about the reliability of the
information provided in bug reports.

Ciao,
Dscho

Where do we want to go with this? After the discussion and sleeping on
it, I'm still of the mind that we should generally default things to
being builtins unless there's an immediate need not to do so (like
extra link dependencies). But I don't care _too_ much, so I'd rather
eject this patch and move forward with the rest of the series if it's a
sticking point. Thoughts?

Just now catching up. I think it's a fine idea to turn it into a
builtin. As stated elsewhere, this means the version reported is more
reliable (and saves me work which I had on my list to query 'git
version' instead of listing the version when git-bugreport was built).
It's true that there is more work to do on bugreport, it's true that
that work is moving very slowly, as I had a number of things on my plate
even before the world turned upside down :) At the time, Junio seemed
inclined to take git-bugreport as a standalone, and I didn't care very
much one way or another, so it seemed like a fine way to get the series
out of review and into use. As I said then, turning it into a builtin
down the road isn't difficult - so I'm happy with the general direction.

I already said what needs to be said.

I do not care too deeply what we do now today either way, as long as
people remember that we are interested in the version string, build
options and external library versions of the "git" binary (for
built-ins) and non-built-in binaries (like the remote helpers), and
not as much interested in these traits of the "git-bugreport" binary
itself, when we need to split "bugreport" out of builtins in the
future.

Ironically, making it built-in eliminates the chance of sloppy code
to report versions and other traits of git-bugreport that does not
matter and is different from these traits of git itself, but it will
make the technical burden larger if we ever need to split.  It won't
be just the matter of giving it a new cmd_main() and worry about the
optional nongit setup.

Thanks.

I guess my question was really: after the discussion do you think I'm
being an idiot, to the point that you do not want to pick up the series?

It sounds like the answer is no, and...

Yes, I agree that future changes to bugreport may need to keep that in
mind (but my guess is that it won't even ever come up).

And I saw no surprises in the diff. As stated in
https://lore.kernel.org/git/20200817121239.GA44309@google.com I think
this is a fine idea, so:

[PATCH 4/5] make git-fast-import a builtin

[Jeff King]

There's no reason that git-fast-import benefits from being a separate
binary. And as it links against libgit.a, it has a non-trivial disk
footprint. Let's make it a builtin, which reduces the size of a stripped
installation from 22MB to 21MB.

[PATCH 5/5] drop vcs-svn experiment

[Jeff King]

The code in vcs-svn was started in 2010 as an attempt to build a
remote-helper for interacting with svn repositories (as opposed to
git-svn). However, we never got as far as shipping a mature remote
helper, and the last substantive commit was e99d012a6bc in 2012.

We do have a git-remote-testsvn, and it is even installed as part of
"make install". But given the name, it seems unlikely to be used by
anybody (you'd have to explicitly "git clone testsvn::$url", and there
have been zero mentions of that on the mailing list since 2013, and even
that includes the phrase "you might need to hack a bit to get it working
properly"[1]).

We also ship contrib/svn-fe, which builds on the vcs-svn work. However,
it does not seem to build out of the box for me, as the link step misses
some required libraries for using libgit.a. Curiously, the original
build breakage bisects for me to eff80a9fd9 (Allow custom "comment
char", 2013-01-16), which seems unrelated. There was an attempt to fix
it in da011cb0e7 (contrib/svn-fe: fix Makefile, 2014-08-28), but on my
system that only switches the error message.

So it seems like the result is not really usable by anybody in practice.
It would be wonderful if somebody wanted to pick up the topic again, and
potentially it's worth carrying around for that reason. But the flip
side is that people doing tree-wide operations have to deal with this
code.  And you can see the list with (replace "HEAD" with this commit as
appropriate):

  {
    echo "--"
    git diff-tree --diff-filter=D -r --name-only HEAD^ HEAD
  } |
  git log --no-merges --oneline e99d012a6bc.. --stdin

which shows 58 times somebody had to deal with the code, generally due
to a compile or test failure, or a tree-wide style fix or API change.
Let's drop it and let anybody who wants to pick it up do so by
resurrecting it from the git history.

As a bonus, this also reduces the size of a stripped installation of Git
from 21MB to 19MB.

-NAME
-----
-svn-fe - convert an SVN "dumpfile" to a fast-import stream
-
-SYNOPSIS
---------
-[verse]
-mkfifo backchannel &&
-svnadmin dump --deltas REPO |
-	svn-fe [url] 3<backchannel |
-	git fast-import --cat-blob-fd=3 3>backchannel
-
-DESCRIPTION
------------
-
-Converts a Subversion dumpfile into input suitable for
-git-fast-import(1) and similar importers. REPO is a path to a
-Subversion repository mirrored on the local disk. Remote Subversion
-repositories can be mirrored on local disk using the `svnsync`
-command.
-
-Note: this tool is very young.  The details of its commandline
-interface may change in backward incompatible ways.
-
-INPUT FORMAT
-------------
-Subversion's repository dump format is documented in full in
-`notes/dump-load-format.txt` from the Subversion source tree.
-Files in this format can be generated using the 'svnadmin dump' or
-'svk admin dump' command.
-
-OUTPUT FORMAT
--------------
-The fast-import format is documented by the git-fast-import(1)
-manual page.
-
-NOTES
------
-Subversion dumps do not record a separate author and committer for
-each revision, nor do they record a separate display name and email
-address for each author.  Like git-svn(1), 'svn-fe' will use the name
-
----------
-user <user@UUID>
----------
-
-as committer, where 'user' is the value of the `svn:author` property
-and 'UUID' the repository's identifier.
-
-To support incremental imports, 'svn-fe' puts a `git-svn-id` line at
-the end of each commit log message if passed a URL on the command
-line.  This line has the form `git-svn-id: URL@REVNO UUID`.
-
-The resulting repository will generally require further processing
-to put each project in its own repository and to separate the history
-of each branch.  The 'git filter-repo --subdirectory-filter' command
-may be useful for this purpose.
-
-BUGS
-----
-Empty directories and unknown properties are silently discarded.
-
-The exit status does not reflect whether an error was detected.

-line_buffer API
-===============
-
-The line_buffer library provides a convenient interface for
-mostly-line-oriented input.
-
-Each line is not permitted to exceed 10000 bytes.  The provided
-functions are not thread-safe or async-signal-safe, and like
-`fgets()`, they generally do not function correctly if interrupted
-by a signal without SA_RESTART set.
-
-Calling sequence
-----------------
-
-The calling program:
-
- - initializes a `struct line_buffer` to LINE_BUFFER_INIT
- - specifies a file to read with `buffer_init`
- - processes input with `buffer_read_line`, `buffer_skip_bytes`,
-   and `buffer_copy_bytes`
- - closes the file with `buffer_deinit`, perhaps to start over and
-   read another file.
-
-When finished, the caller can use `buffer_reset` to deallocate
-resources.
-
-Using temporary files
----------------------
-
-Temporary files provide a place to store data that should not outlive
-the calling program.  A program
-
- - initializes a `struct line_buffer` to LINE_BUFFER_INIT
- - requests a temporary file with `buffer_tmpfile_init`
- - acquires an output handle by calling `buffer_tmpfile_rewind`
- - uses standard I/O functions like `fprintf` and `fwrite` to fill
-   the temporary file
- - declares writing is over with `buffer_tmpfile_prepare_to_read`
- - can re-read what was written with `buffer_read_line`,
-   `buffer_copy_bytes`, and so on
- - can reuse the temporary file by calling `buffer_tmpfile_rewind`
-   again
- - removes the temporary file with `buffer_deinit`, perhaps to
-   reuse the line_buffer for some other file.
-
-When finished, the calling program can use `buffer_reset` to deallocate
-resources.
-
-Functions
----------
-
-`buffer_init`, `buffer_fdinit`::
-	Open the named file or file descriptor for input.
-	buffer_init(buf, NULL) prepares to read from stdin.
-	On failure, returns -1 (with errno indicating the nature
-	of the failure).
-
-`buffer_deinit`::
-	Stop reading from the current file (closing it unless
-	it was stdin).  Returns nonzero if `fclose` fails or
-	the error indicator was set.
-
-`buffer_read_line`::
-	Read a line and strip off the trailing newline.
-	On failure or end of file, returns NULL.
-
-`buffer_copy_bytes`::
-	Read `len` bytes of input and dump them to the standard output
-	stream.  Returns early for error or end of file.
-
-`buffer_skip_bytes`::
-	Discards `len` bytes from the input stream (stopping early
-	if necessary because of an error or eof).  Return value is
-	the number of bytes successfully read.
-
-`buffer_reset`::
-	Deallocates non-static buffers.

I have nothing to add to this email other than to say that I think it
makes sense to remove this. I agree it would be nice if somebody picked
it up, but given that nothing has really changed since ~8 years ago, I
think that it's unlikely to happen in the next ~8 years ;).

At least, it seems unlikely enough that dropping 2MB from the
installation size is worth it. If someone *is* interested in picking it
up, I'm sure that they won't have trouble finding this patch and
reverting it.

Thanks.

TBH I care less about the installation size (which we could easily fix
by just not installing git-remote-testsvn) and more that it's 3000 lines
of basically-dead code. That keeps getting touched for tree-wide
refactors (most recently for strvec, but my -Wunused-parameters series
was the straw that caused me to just delete it instead).

I don't think resurrecting it will be quite as easy as reverting this.
Because the rest of the code will move on, so it will probably need
some fixups, depending on how long it has been. But those fixups are the
exact same changes we're saving regular git developers from doing. So
it's really just gambling that we won't need to do them (and also
shifting the work from everybody onto whoever chooses to work on this).

It would be nice if it could be spun out independently, but it does use
a bunch of data structures from libgit.a, which complicates that.

FWIW I got it to work, as part of my initial patches to support
`init.defaultBranch`. I even included a patch to touch `svn-fe` up in the
patch thicket to demonstrate how we can move from `master` as Git's
default branch to `main`.

However, given that Subversion usage has declined so dramatically over the
past ten years, I am inclined to agree with you that it makes sense to
drop `testsvn` as well as `svn-fe`.

Thanks,
Dscho

> -----
> -svn-fe - convert an SVN "dumpfile" to a fast-import stream
> -
> -SYNOPSIS
> ---------
> -[verse]
> -mkfifo backchannel &&
> -svnadmin dump --deltas REPO |
> -	svn-fe [url] 3<backchannel |
> -	git fast-import --cat-blob-fd=3 3>backchannel
> -
> -DESCRIPTION
> ------------
> -
> -Converts a Subversion dumpfile into input suitable for
> -git-fast-import(1) and similar importers. REPO is a path to a
> -Subversion repository mirrored on the local disk. Remote Subversion
> -repositories can be mirrored on local disk using the `svnsync`
> -command.
> -
> -Note: this tool is very young.  The details of its commandline
> -interface may change in backward incompatible ways.
> -
> -INPUT FORMAT
> -------------
> -Subversion's repository dump format is documented in full in
> -`notes/dump-load-format.txt` from the Subversion source tree.
> -Files in this format can be generated using the 'svnadmin dump' or
> -'svk admin dump' command.
> -
> -OUTPUT FORMAT
> --------------
> -The fast-import format is documented by the git-fast-import(1)
> -manual page.
> -
> -NOTES
> ------
> -Subversion dumps do not record a separate author and committer for
> -each revision, nor do they record a separate display name and email
> -address for each author.  Like git-svn(1), 'svn-fe' will use the name
> -
> ----------
> -user <user@UUID>
> ----------
> -
> -as committer, where 'user' is the value of the `svn:author` property
> -and 'UUID' the repository's identifier.
> -
> -To support incremental imports, 'svn-fe' puts a `git-svn-id` line at
> -the end of each commit log message if passed a URL on the command
> -line.  This line has the form `git-svn-id: URL@REVNO UUID`.
> -
> -The resulting repository will generally require further processing
> -to put each project in its own repository and to separate the history
> -of each branch.  The 'git filter-repo --subdirectory-filter' command
> -may be useful for this purpose.
> -
> -BUGS
> -----
> -Empty directories and unknown properties are silently discarded.
> -
> -The exit status does not reflect whether an error was detected.

> -Calling sequence
> -----------------
> -
> -The calling program:
> -
> - - initializes a `struct line_buffer` to LINE_BUFFER_INIT
> - - specifies a file to read with `buffer_init`
> - - processes input with `buffer_read_line`, `buffer_skip_bytes`,
> -   and `buffer_copy_bytes`
> - - closes the file with `buffer_deinit`, perhaps to start over and
> -   read another file.
> -
> -When finished, the caller can use `buffer_reset` to deallocate
> -resources.
> -
> -Using temporary files
> ----------------------
> -
> -Temporary files provide a place to store data that should not outlive
> -the calling program.  A program
> -
> - - initializes a `struct line_buffer` to LINE_BUFFER_INIT
> - - requests a temporary file with `buffer_tmpfile_init`
> - - acquires an output handle by calling `buffer_tmpfile_rewind`
> - - uses standard I/O functions like `fprintf` and `fwrite` to fill
> -   the temporary file
> - - declares writing is over with `buffer_tmpfile_prepare_to_read`
> - - can re-read what was written with `buffer_read_line`,
> -   `buffer_copy_bytes`, and so on
> - - can reuse the temporary file by calling `buffer_tmpfile_rewind`
> -   again
> - - removes the temporary file with `buffer_deinit`, perhaps to
> -   reuse the line_buffer for some other file.
> -
> -When finished, the calling program can use `buffer_reset` to deallocate
> -resources.
> -
> -Functions
> ----------
> -
> -`buffer_init`, `buffer_fdinit`::
> -	Open the named file or file descriptor for input.
> -	buffer_init(buf, NULL) prepares to read from stdin.
> -	On failure, returns -1 (with errno indicating the nature
> -	of the failure).
> -
> -`buffer_deinit`::
> -	Stop reading from the current file (closing it unless
> -	it was stdin).  Returns nonzero if `fclose` fails or
> -	the error indicator was set.
> -
> -`buffer_read_line`::
> -	Read a line and strip off the trailing newline.
> -	On failure or end of file, returns NULL.
> -
> -`buffer_copy_bytes`::
> -	Read `len` bytes of input and dump them to the standard output
> -	stream.  Returns early for error or end of file.
> -
> -`buffer_skip_bytes`::
> -	Discards `len` bytes from the input stream (stopping early
> -	if necessary because of an error or eof).  Return value is
> -	the number of bytes successfully read.
> -
> -`buffer_reset`::
> -	Deallocates non-static buffers.

In my case I needed to specify both -lpthread (common for Unix systems)
and -lpcre (uncommon; I set USE_LIBPCRE).

It looks like it tries to use PTHREAD_LIBS automatically, but that's
only defined in the Makefile for most platforms, not any of the
config.mak.* we include. However, I think it would be defined if I used
autoconf.

So I can _almost_ build with:

  make PTHREAD_LIBS='-lpthread -lpcre2-8'

But it still doesn't work, because the code which uses those (and -lz,
which the Makefile does know about) is in the static libraries
(libgit.a, etc). So the -l libs need to come after that. I needed:

diff --git a/contrib/svn-fe/Makefile b/contrib/svn-fe/Makefile
index e8651aaf4b..b90cf876cd 100644
--- a/contrib/svn-fe/Makefile

 svn-fe.o: svn-fe.c ../../vcs-svn/svndump.h
 	$(QUIET_CC)$(CC) $(CFLAGS) -I../../vcs-svn -o $*.o -c $<

So I'm sure somebody determined could get it to work, and it's
definitely salvageable. But given the lack of questions or reports about
this long-standing breakage on the list, I suspect that nobody is
actually building it in practice.

Looks all very good to me, and I'm certainly a fan of being able to drop
the installation size down substantially as you have done here. I didn't
comment on patches 3 and 4, since they are obviously correct and a good
thing to be doing.

It would be interesting to think about how we might prevent someone from
introducing something that should be a builtin and has to link against
libgit.a other than looking for it carefully in review, but that's
definitely outside the scope of what you're trying to do here.

Thanks.
