As discussed in 644de29e22 (http: drop support for curl < 7.19.4,
2021-07-30) checking against LIBCURL_VERSION_NUM isn't as reliable as
checking specific symbols present in curl, as some distros have been
known to backport features.
However, while some of the curl_easy_setopt() arguments we rely on are
macros, others are enum, and we can't assume that those that are
macros won't change into enums in the future.
So we're still going to have to check LIBCURL_VERSION_NUM, but by
doing that in one central place and using a macro definition of our
own, anyone who's backporting features can define it themselves, and
thus have access to more modern curl features that they backported,
even if they didn't bump the LIBCURL_VERSION_NUM.
More importantly, as shown in a preceding commit doing these version
checks makes for hard to read and possibly buggy code, as shown by the
bug fixed there where we were conflating base 10 for base 16 when
comparing the version.
By doing them all in one place we'll hopefully reduce the chances of
such future mistakes, furthermore it now becomes easier to see at a
glance what the oldest supported version is, which makes it easier to
reason about any future deprecation similar to the recent
e48a623dea (Merge branch 'ab/http-drop-old-curl', 2021-08-24).

In d73019feb4 (http: add support selecting http version, 2018-11-08)
a dependency was added on CURL_HTTP_VERSION_2, but this feature was
introduced in curl version 7.43.0, not 7.47.0, as the incorrect
version check led us to believe.
As looking through the history of that commit on the mailing list will
reveal[1], the reason for this is that an earlier version of it
depended on CURL_HTTP_VERSION_2TLS, which was introduced in libcurl
7.47.0.
But the version that made it in in d73019feb4 had dropped the
dependency on CURL_HTTP_VERSION_2TLS, but the corresponding version
check was not corrected.
The newest symbol we depend on is CURL_HTTP_VERSION_2. It was added in
7.33.0, but the CURL_HTTP_VERSION_2 alias we used was added in
7.47.0. So we could support an even older version here, but let's just
correct the checked version.

dropped support for curl < 7.19.4, so we can drop support for this

It's non-obvious because in curl's hex version notation 0x071800 is
version 7.24.0, *not* 7.18.0, so at a glance this patch looks
incorrect.
But it's correct, because the existing version check being removed

CURLPROXY_SOCKS4 7.10
CURLPROXY_SOCKS4A 7.18.0
CURLPROXY_SOCKS5 7.10
CURLPROXY_SOCKS5_HOSTNAME 7.18.0
I.e. the oldest version that has these is in fact 7.18.0, not
7.24.0. That we were checking 7.24.0 is just an mistake in

In the last commit we dropped support for curl < 7.16.0, let's
continue that and drop support for versions older than 7.19.3. This
allows us to simplify the code by getting rid of some "#ifdef"'s.
Git was broken with vanilla curl < 7.19.4 from v2.12.0 until
v2.15.0. Compiling with it was broken by using CURLPROTO_* outside any
"#ifdef" in aeae4db174 (http: create function to get curl allowed
protocols, 2016-12-14), and fixed in v2.15.0 in f18777ba6e (http: fix

It's unclear how much anyone was impacted by that in practice, since
as noted in [1] RHEL versions using curl older than that still
compiled, because RedHat backported some features. Perhaps other
vendors did the same.
Still, it's one datapoint indicating that it wasn't in active use at
the time. That (the v2.12.0 release) was in Feb 24, 2017, with v2.15.0
on Oct 30, 2017, it's now mid-2021.

Choosing 7.16.0 is a somewhat arbitrary cutoff:

Besides being a nice round number, around 10 years is
a common end-of-life support period, even for conservative
distributions.
2. That version introduced the curl_multi interface, which

RHEL 5 came with curl 7.15.5[1] (released in August 2006). RHEL 5's
extended life cycle program ended on 2020-11-30[1]. RHEL 6 comes with

7.29.0 (released in February 2013).

This reverts commit 1b0d9545bb.
That commit does fix the situation it intended to (avoiding Negotiate
even when the credentials were provided in the URL), but it creates a
more serious regression: we now never hit the conditional for "we had a
username and password, tried them, but the server still gave us a 401".
That has two bad effects:
1. we never call credential_reject(), and thus a bogus credential
stored by a helper will live on forever
2. we never return HTTP_NOAUTH, so the error message the user gets is
"The requested URL returned error: 401", instead of "Authentication
failed".
Doing this correctly seems non-trivial, as we don't know whether the
Negotiate auth was a problem. Since this is a regression in the upcoming
v2.23.0 release (for which we're in -rc0), let's revert for now and work
on a fix separately.
(Note that this isn't a pure revert; the previous commit added a test

Code which split an argv_array call across multiple lines, like:

was recently mechanically renamed to use strvec, which results in
mis-matched indentation like:
strvec_pushl(&args, "one argument",
"another argument", "and more",
NULL);
Let's fix these up to align the arguments with the opening paren. I did
this manually by sifting through the results of:
git jump grep 'strvec_.*,$'
and liberally applying my editor's auto-format. Most of the changes are
of the form shown above, though I also normalized a few that had
originally used a single-tab indentation (rather than our usual style of
aligning with the open paren). I also rewrapped a couple of obvious
cases (e.g., where previously too-long lines became short enough to fit
on one), but I wasn't aggressive about it. In cases broken to three or
more lines, the grouping of arguments is sometimes meaningful, and it
wasn't worth my time or reviewer time to ponder each case individually.

We eventually want to drop the argv_array name and just use strvec

Because of our preprocessor compat layer, the names are interchangeable
to the compiler (so even a definition and declaration using different
names is OK).
This patch converts remaining files from the first half of the alphabet,
to keep the diff to a manageable size.
The conversion was done purely mechanically with:
git ls-files '*.c' '*.h' |
xargs perl -i -pe '
s/ARGV_ARRAY/STRVEC/g;
s/argv_array/strvec/g;
'
and then selectively staging files with "git add '[abcdefghjkl]*'".

finish_http_pack_request() does multiple tasks, including some
housekeeping on a struct packed_git - (1) closing its index, (2)
removing it from a list, and (3) installing it. These concerns are
independent of fetching a pack through HTTP: they are there only because
(1) the calling code opens the pack's index before deciding to fetch it,
(2) the calling code maintains a list of packfiles that can be fetched,
and (3) the calling code fetches it in order to make use of its objects
in the same process.
In preparation for a subsequent commit, which adds a feature that does
not need any of this housekeeping, remove (1), (2), and (3) from
finish_http_pack_request(). (2) and (3) are now done by a helper
function, and (1) is the responsibility of the caller (in this patch,

When Git fetches a pack using dumb HTTP, (among other things) it invokes
index-pack on a ".pack.temp" packfile, specifying the filename as an
argument.
A future commit will require the aforementioned invocation of index-pack
to also generate a "keep" file. To use this, we either have to use
index-pack's naming convention (because --keep requires the pack's
filename to end with ".pack") or to pass the pack through stdin. Of the
two, it is simpler to pass the pack through stdin.
Thus, teach http to pass --stdin to index-pack. As a bonus, the code is
now simpler.

We may feed a URL like "cert:///path/to/cert.pem" into the credential
machinery to get the key for a client-side certificate. That
credential has no hostname field, which is about to be disallowed (to
avoid confusion with protocols where a helper _would_ expect a
hostname).
This means as of the next patch, credential helpers won't work for
unlocking certs. Let's fix that by doing two things:
- when we parse a url with an empty host, set the host field to the
empty string (asking only to match stored entries with an empty
host) rather than NULL (asking to match _any_ host).
- when we build a cert:// credential by hand, similarly assign an
empty string
It's the latter that is more likely to impact real users in practice,
since it's what's used for http connections. But we don't have good
infrastructure to test it.

In 93b980e58f (http: use xmalloc with cURL, 2019-08-15), we started to
ask cURL to use `xmalloc()`, and if compiled with nedmalloc, that means
implicitly a different allocator than the system one.
Which means that all of cURL's allocations and releases now _need_ to
use that allocator.
However, the `http_options()` function used `slist_append()` to add any
configured extra HTTP header(s) _before_ asking cURL to use `xmalloc()`,
and `http_cleanup()` would release them _afterwards_, i.e. in the
presence of custom allocators, cURL would attempt to use the wrong
allocator to release the memory.
A naïve attempt at fixing this would move the call to
`curl_global_init()` _before_ the config is parsed (i.e. before that
call to `slist_append()`).
However, that does not work, as we _also_ parse the config setting
`http.sslbackend` and if found, call `curl_global_sslset()` which *must*
be called before `curl_global_init()`, for details see:
https://curl.haxx.se/libcurl/c/curl_global_sslset.html
So let's instead make the config parsing entirely independent from
cURL's data structures. Incidentally, this deletes two more lines than
it introduces, which is nice.

The fread/fwrite-like functions in http.c, namely fread_buffer,

Practically speaking, it doesn't matter, because in all contexts where

But those functions being similar to fread and fwrite (the curl API is
designed around being able to use fread and fwrite directly), it might
be preferable to make them behave like fread and fwrite, which, from
the fread/fwrite manual page, is:
On success, fread() and fwrite() return the number of items read
or written. This number equals the number of bytes transferred
only when size is 1. If an error occurs, or the end of the file
is reached, the return value is a short item count (or zero).

hex without checking if it could be parsed. This could lead to us
looking at uninitialized garbage in the hash array. In practice this
means we'll just make a garbage request to the server which will

The loose object access code in sha1-file.c is some of the oldest in

for object ids, which these days should be "struct object_id".
It also uses the term "sha1_file" in many functions, which is confusing.
The term "loose_objects" is much better. It clearly distinguishes
them from packed objects (which didn't even exist back when the name
"sha1_file" came into being). And it also distinguishes it from the
checksummed-file concept in csum-file.c (which until recently was
actually called "struct sha1file"!).
This patch converts the functions {open,close,map,stat}_sha1_file() into
open_loose_object(), etc, and switches their sha1 arguments for
object_id structs. Similarly, path functions like fill_sha1_path()
become fill_loose_path() and use object_ids.
The function sha1_loose_object_info() already says "loose", so we can
just drop the "sha1" (and teach it to use object_id).

The dumb-http walker code still passes around and stores object ids as
"unsigned char *sha1". Let's modernize it.
There's probably still more work to be done to handle dumb-http fetches
with a new, larger hash. But that can wait; this is enough that we can
now convert some of the low-level object routines that we call into from
here (and in fact, some of the "oid.hash" references added here will be
further improved in the next patch).

The sha1_file_name() function is used to generate the path to a loose
object in the object directory. It doesn't make much sense for it to
append, since the the path we write may be absolute (i.e., you cannot
reliably build up a path with it). Because many callers use it with a
static buffer, they have to strbuf_reset() manually before each call
(and the other callers always use an empty buffer, so they don't care
either way). Let's handle this automatically.
Since we're changing the semantics, let's take the opportunity to give
it a more hash-neutral name (which will also catch any callers from
topics in flight).

Usually we don't need to set libcurl to choose which version of the
HTTP protocol to use to communicate with a server.
But different versions of libcurl, the default value is not the same.
CURL >= 7.62.0: CURL_HTTP_VERSION_2TLS
CURL < 7.62: CURL_HTTP_VERSION_1_1
In order to give users the freedom to control the HTTP version,
we need to add a setting to choose which HTTP version to use.

When a requested feature cannot be activated because the version of
cURL library used to build Git with is too old, most of the codepaths
give a warning like "$Feature is not supported with cURL < $Version",
marked for l10n. A few of them, however, did not follow that pattern
and said things like "$Feature is not activated, your curl version is
too old (>= $Version)", and without marking them for l10n.
Update these to match the style of the majority of warnings and mark
them for l10n.

As of cURL v7.60.0, the Secure Channel backend can use the certificate
bundle provided via `http.sslCAInfo`, but that would override the
Windows Certificate Store. Since this is not desirable by default, let's
tell Git to not ask cURL to use that bundle by default when the `schannel`
backend was configured via `http.sslBackend`, unless
`http.schannelUseSSLCAInfo` overrides this behavior.

This adds support for a new http.schannelCheckRevoke config value.
This config value is only used if http.sslBackend is set to "schannel",
which forces cURL to use the Windows Certificate Store when validating
server certificates associated with a remote server.
This config value should only be set to "false" if you are in an
environment where revocation checks are blocked by the network, with
no alternative options.
This is only supported in cURL 7.44 or later.
Note: originally, we wanted to call the config setting
`http.schannel.checkRevoke`. This, however, does not work: the `http.*`
config settings can be limited to specific URLs via `http.<url>.*`
(and this feature would mistake `schannel` for a URL).

As of version 7.56.0, curl supports being compiled with multiple SSL
backends.
This patch adds the Git side of that feature: by setting http.sslBackend
to "openssl" or "schannel", Git for Windows can now choose the SSL
backend at runtime.
This comes in handy on Windows because Secure Channel ("schannel") is
the native solution, accessing the Windows Credential Store, thereby
allowing for enterprise-wide management of certificates. For historical
reasons, Git for Windows needs to support OpenSSL still, as it has
previously been the only supported SSL backend in Git for Windows for
almost a decade.
The patch has been carried in Git for Windows for over a year, and is
considered mature.

This rounds out the previous three patches, covering the
inequality logic for the "hash" variant of the functions.
As with the previous three, the accompanying code changes
are the mechanical result of applying the coccinelle patch;
see those patches for more discussion.
