Output the current UTC time using strftime format. %f is an extra curl
specific flag to output the microsecond fraction of the current second.

Makes curl follow redirects an act on the response code and change a
custom method accordingly, contrary to --location.
Potential future command line to send QUERY and following a redirect
according to the status code:
curl -d "request-body" -X QUERY --follow https://example.com

Closes#16543
When doing HTTP/2 and HTTP/3, it is possible to achieve quite a massive
parallelism so limiting this to 300 seems restrictive.
With other protocols, going beyond 300-400 might not be recommended but
curl does not have to enforce the limit.
Closes#18068
Add a new commandline option --out-null that discards all
response bytes into the void. Replaces non-portable use of
'-o /dev/null' with more efficiency.
Feature added in 8.16.0
Closes#17800
If the long option name ends with an equals sign (`=`), the argument is
the text following on its right side.
This makes the command line parser accept this common style in addition
to the existing way to accept option arguments more similar to how other
command line tools do.
Example: `curl --user-agent=curl-2000 https://example.com/`
Change a few existing tests to use this syntax: 206, 1333, 1335, 1442
Closes#17789
Without a libcurl built with the SSLS-EXPORT feature this command line
option produces:
curl: option --ssl-sessions: the installed libcurl version does not support this
curl: try 'curl --help' or 'curl --manual' for more information
Add a note of warning on the -ssl-session docs page to account for this.
Closes#17909
curl passes down the capath directly to the backends. OpenSSL will then
delimiter-separate this path internally to support multiple directories
(using its certificate hash scheme). However, the other backends
(wolfSSL, mbedTLS, gnutls) only expect a single directory (and do not
use the hash scheme, preferring to iterate the directory and load all
files). This adjusts the `--capath` documentation to reflect that
multiple paths is an OpenSSL-specific feature. Alternatively, curl could
delimiter-separate these itself, but I'm not sure it's worth it.

Make test bundles the default. Drop non-bundle build mode.
Also do all the optimizations and tidy-ups this allows, simpler builds,
less bundle exceptions, streamlined build mechanics.
Also rework the init/deinit macro magic for unit tests. The new method
allows using unique init/deinit function names, and calling them with
arguments. This is in turn makes it possible to reduce the use of global
variables.
Note this drop existing build options `-DCURL_TEST_BUNDLES=` from cmake
and `--enable-test-bundles` / `--disable-test-bundles` from autotools.
Also:
- rename test entry functions to have unique names: `test_<testname>`
This removes the last exception that was handled in the generator.
- fix `make dist` to not miss test sources with test bundles enabled.
- sync and merge `tests/mk-bundle.pl` into `scripts/mk-unity.pl`.
- mk-unity.pl: add `--embed` option and use it when `CURL_CLANG_TIDY=ON`
to ensure that `clang-tidy` does not miss external test C sources.
(because `clang-tidy` ignores code that's #included.)
- tests/unit: drop no-op setup/stop functions.
- tests: reduce symbol scopes, global macros, other fixes and tidy-ups.
- tool1621: fix to run, also fix it to pass.
- sockfilt: fix Windows compiler warning in certain unity include order,
by explicitly including `warnless.h`.

These libraries do not support TLS 1.3 and have been marked for removal
for over a year. We want to help users select a TLS dependency that is
future-proof and reliable, and not supporting TLS 1.3 in 2025 does not
infer confidence. Users who build libcurl are likely to be served better
and get something more future-proof with a TLS library that supports
1.3.
Closes#16677
This boolean option was moved to the wrong handling function. Make it
an ARG_NONE and move it to the correct handler and add a test to
verify that the option works.

After Gmail called out the typo I fixed on
532d89a866, I've decided to paste the
whole man page into Google docs and check what other issues it would
spot.
I know, it sounds silly, but I've just spent the last hour and a half
going over each one of them and fixing everything which was a true
finding and non-controversial.
Closes#17480
To avoid redundant work in CI and to avoid a single checksrc issue make
all autotools jobs fail. After this patch checksrc issues make fail
the checksrc job, the `dist / verify-out-of-tree-autotools-debug`,
`dist / maketgz-and-verify-in-tree` jobs and the fuzzer job (if run).
Of these, the `dist` jobs replicate local builds, also testing the build
logic.
Also add a script to check the complete local repository, optionally
with the build tree to verify generated C files.
Also:
- automatically run checksrc in subdirectories having a `checksrc`
target. (examples, OS400, tests http/client, unit and tunit)
- tests/libtest: make sure to run `checksrc` on generated `lib1521.c`.
(requires in-tree autotools build.)
- tests: run `checksrc` on targets also for non-`DEBUGBUILD`
builds. It ensures to check `lib1521.c` in CI via job
`dist / maketgz-and-verify-in-tree`.
- src: drop redundant `$(builddir)` in autotools builds.
- scripts: add `checksrc-all.sh` script to check all C sources and
the build directory as an option.
- use the above from CI, also make it verify all generated sources.
- silence `checksrc` issues in generated C sources.
- checksrc: add `-v` option to enable verbose mode.
- checksrc: make verbose mode show checked filename and fix to only
return error on failure.
- make sure that generated C files pass `checksrc`.

This document now lists all previous releases.
This allows us to verify that documentation refers to actual release
versions.
Test 971 now verifies options-in-versions and all command line options
documentation individually. Fixed a few discrepancies.
Test 1488 verifies libcurl options "Added-in" to exist. Fixed a few
discrepancies there as well.
Closes#16907
With rustls-ffi 0.15+ we can set up a callback for writing TLS secrets
hooked up to call Curl_tls_keylog_write. To make sure the associated
file is cleaned up we update the Curl_ssl struct for the rustls-ffi vtls
backend to have a cleanup callback.
