Used for extracting:
- when used asking for a scheme, it will return CURLUE_NO_SCHEME if the
stored information was a guess
- when used asking for a URL, the URL is returned without a scheme, like
when previously given to the URL parser when it was asked to guess
- as soon as the scheme is set explicitly, it is no longer internally
marked as guessed
The idea being:
1. allow a user to figure out if a URL's scheme was set as a result of
guessing
2. extract the URL without a guessed scheme
3. this makes it work similar to how we already deal with port numbers
Extend test 1560 to verify.

Like when we list a series of options and then want to add "normal" text
again afterwards.
Without this, the indentation level wrongly continues even after the
final "##" header, making following text wrongly appear to belong to the
header above.
Adjusted several curldown files to use this.

- Revert to the legacy TLS 1.2 key logging code for LibreSSL.
- Document SSLKEYLOGFILE for LibreSSL is TLS 1.2 max.
Prior to this change if the user specified a filename in the
SSLKEYLOGFILE environment variable and was using LibreSSL 3.5.0+ then
an empty file would be created and no keys would be logged.
This is effectively a revert of e43474b4 which changed openssl.c to use
SSL_CTX_set_keylog_callback for LibreSSL 3.5.0+. Unfortunately LibreSSL
added that function only as a stub that doesn't actually do anything.

Closes https://github.com/curl/curl/pull/13682
curl drops support for TLS libraries without TLS 1.3 capability after
May 2025.
It requires that a curl build using the library should be able to
negotiate and use TLS 1.3, or else it is not good enough. We support a
vast amount of other TLS libraries that are likely to satisfy users
better.
Closes#13544
- Clear data->state.os_errno before transfer.
- Explain the change in behavior in the CURLINFO_OS_ERRNO doc.
- Add to the CURLINFO_OS_ERRNO doc the list of libcurl network-related
errors that may cause the errno to be saved.
data->state.os_errno is saved before libcurl returns a network-related
failure such as connection failure. It is accessible to the user via
CURLINFO_OS_ERRNO so they can get more information about the failure.
Prior to this change it wasn't cleared before transfer, so if a user
retrieved the saved errno it could be from a previous transfer. That is
because an errno is not always saved for network-related errors.

CURLOPT_EGDSOCKET and CURLOPT_RANDOM_FILE are both completely dead

with this option) so we refrain from documenting it here.

Use a lookup list to set the cipher suites, allowing the

- Call OPENSSL_thread_stop on thread termination (DLL_THREAD_DETACH)
to prevent a memory leak in case OpenSSL is linked statically.
- Warn in libcurl-thread.3 that if OpenSSL is linked statically then it
may require thread cleanup.
OpenSSL may need per-thread cleanup to stop a memory leak. For Windows
and Cygwin if libcurl was built as a DLL then we can do that for the
user by calling OPENSSL_thread_stop on thread termination. However, if
libcurl was built statically then we do not have notification of thread
termination and cannot do that for the user.
Also, there are several other unusual cases where it may be necessary
for the user to call OPENSSL_thread_stop, so in the libcurl-thread
warning I added a link to the OpenSSL documentation.

Closes#13452
By default the API inhibits empty queries and fragments extracted.
Unless this new flag is set.
This also makes the behavior more consistent: without it set, zero
length queries and fragments are considered not present in the URL. With
the flag set, they are returned as a zero length strings if they were in
fact present in the URL.
This applies when extracting the individual query and fragment
components and for the full URL.

This time limit the number of files per command to avoid exceeding
limitations of certain OS/shell envs.
Such known env is Windows with the `cmd.exe` shell, which features an

Allowlisting `UNIX` to have no limit and using a limit of 200 for other
envs to be safe. If there is a way to detect `cmd.exe` and/or we know
which precise envs are sensitive to this, we can tweak these conditions
further.
Even with the low limit, this patch reduces external commands by 200x,
making builds much faster.

This commit updates the optional rustls-ffi librustls dependency from
0.12.0 to 0.13.0. This version is based on the latest available rustls
release (0.23.4).
The breaking API changes from 0.12.0 to 0.13.0 are in API surface unused
by curl, so this is an in-place update without any code changes.
The `RUSTLS.md` documentation is updated to reflect the new version in
use, and to clarify that `cbindgen` isn't required to build `librustls`
- it's only used by developers to update the vendored `rustls.h` header
file maintained upstream.

The mandatory header now has a mandatory list of protocols for which the
manpage is relevant.
Most man pages already has a "PROTOCOLS" section, but this introduces a

cd2nroff verifies that at least one protocol is mentioned (which can be
`*`).
This information is not used just yet, but A) the PROTOCOLS section can
now instead get generated and get a unified wording across all manpages
and B) this allows us to more reliably filter/search for protocol
specific manpages/options.
