Drop separate `TrackMemory` (aka `CURLDEBUG`) debug feature.
After recent changes (thread-safety,
193cb00ce9, and updates leading up to
it), `TrackMemory` is unlikely to cause build or runtime issues.
To simplify builds and debug options, enable `TrackMemory`
unconditionally for debug-enabled (aka `DEBUGBUILD`) builds. Before
this patch, this was already the default, with an option to disable
it, or enable it in non-debug-enabled builds.
Note, in practice these two debug options already went hand in hand. It
was not possible to toggle them separately for a long time due to bugs,
before 59dc9f7e69 (2024-05-28) fixed it.
This patch also removes/deprecates separate knobs and feature flags for
`TrackMemory`:
- autotools: `--enable-curldebug`/`--disable-curldebug`
- cmake: `-DENABLE_CURLDEBUG=ON`/`OFF`
- C macro: `CURLDEBUG`
- libcurl: `CURL_VERSION_CURLDEBUG` symbol deprecated in favor
of `CURL_VERSION_DEBUG`. They always return the same value after this
patch.
Also:
- drop `TrackMemory` from `curl -V` output.
- rename internal `CURLDEBUG` macro to `CURL_MEMDEBUG` internally.
To avoid confusion with `DEBUGBUILD`, but to keep guarding
`TrackMemory`-related internals for readability.
- runtests: bind `TrackMemory` to debug feature. Keep it a separate
test feature requirement, for clarity.
- CI: drop test builds for combinations of the two options.
- GHA/linux: no longer disable TrackMemory in the TSAN job.

With the same semantics as Apple SecTrust, in both libcurl and the curl
tool, when using non-Schannel TLS backends. In practice it means that
it makes TLS work without manually or implicitly configuring a CA bundle
`.crt` file, such as `curl-ca-bundle.crt`.
To enable:
- autotools: `--enable-ca-native`
- cmake: `-DCURL_CA_NATIVE=ON`
- CPPFLAGS: `-DCURL_CA_NATIVE`
When enabled:
- enables `CURLSSLOPT_NATIVE_CA` (libcurl) / `--ca-native`
and `--proxy-ca-native` (curl tool) options by default.
- unsafe search for an on-disk CA bundle gets disabled by default.
Equivalent to `--disable-ca-search` with autotools,
`-DCURL_DISABLE_CA_SEARCH=ON` with CMake.
- build-time detection of CA bundle and CA path gets disabled. As with
Apple SecTrust. This was already the default for Windows.
- native CA can be disabled at run-time with the `--no-ca-native`
and/or `--no-proxy-ca-native` command-line options.
Rationale: This build option:
- has a repeat and active interest from packagers and users.
- helps integrating curl with Windows for those who need this.
- it also applies to macOS: #17525
Shipped in curl 8.17.0.
- makes it trivial to use custom certs configured on the OS.
- frees applications/packagers/users from the task of securely
distributing, and keeping up-to-date, a CA bundle.
- frees potentially many curl tool from configuring a CA bundle manually
to access HTTPS (and other TLS) URLs. This is traditionally difficult
on Windows because there is no concept of a universal, protected,
non-world-writable, location on the file system to securely store
a CA bundle.
- allows using modern features regardless of Windows version. Some of
these features are not supported with Schannel (e.g. HTTP/3, ECH) on
any Windows version.
- is necessary for HTTP/3 builds, where bootstrapping a CA bundle is not
possible with Schannel, because MultiSSL is not an option, and HTTP/3
is not supported with Schannel.

To make the texts easier on the eye.
- Remove most free text references to curl versions before 7.60.0 (May
2018)
- Leave those present in a HISTORY section
Most of them are already documented in symbols-in-versions anyway.
Closes#18530
- Clarify that the ssl_version in MultiSSL builds contains all SSL
backend names with the inactive backend names in parentheses.

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
Works better if we later introduce another way to do the asynch RR
resolves (together with the threaded resolver) that does not use c-ares.
Closes#16090
Allow building with c-ares and yet use threaded resolver for the main
host A/AAAA resolving:
`--with-ares` provides the c-ares install path and defaults to use
c-ares for name resolving
`--with-threaded-resolver` still uses c-ares in the build (for HTTPS)
but uses the threaded resolver for "normal" resolves.
It works similarly for cmake: ENABLE_ARES enables ares, and if
ENABLE_THREADED_RESOLVER also is set, c-ares is used for HTTPS RR and
the threaded resolver for "normal" resolves.
HTTPSRR and c-ares-rr are new features return by curl_version_info() and
thus shown by curl -V.
The c-ares-rr feature bit is there to make it possible to distinguish
between builds using c-ares for all name resolves and builds that use
the threaded resolves for the regular name resolves and c-ares for
HTTPSRR only. "c-ares-rr" means it does not use c-ares for "plain" name
resolves.
HTTPSRR support is EXPERIMENTAL only.
Closes#16054
Adds the experimental feature `ssls-export` to libcurl and curl for
importing and exporting SSL sessions from/to a file.
* add functions to libcurl API
* add command line option `--ssl-sessions <filename>` to curl
* add documenation
* add support in configure
* add support in cmake
+ add pytest case
Closes#15924
- make DEFAULT sections less repetitive
- make historic mentions use HISTORY
- generate the protocols section on `# %PROTOCOLS%` instead of guessing
where to put it
- generate the availability section on `# %AVAILABILITY%` instead of
guessing where to put it
- make the protocols section more verbose
Closes#14227
- generate AVAILABILITY manpage sections automatically - for consistent
wording
- allows us to double-check against other documumentation (symbols-in-versions
etc)
- enables proper automation/scripting based on this data
- lots of them were wrong or missing in the manpages
- several of them repeated (sometimes mismatching) backend support info
Add test 1488 to verify "added-in" version numbers against
symbols-in-versions.
Closes#14217
Remove the PROTOCOLS section from the source files completely and
instead generate them based on the header data in the curldown files.
It also generates TLS backend information for options marked for TLS as
protocol.
Closes#13175
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
stricter way to specify the relevant protocols.
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.
Closes#13166
The curldown conversion accidentally replaced daniel@haxx.se with
just daniel.se. This reverts back to the proper email address in
the curldown docs as well as in a few other stray places where it
was incorrect (while unrelated to curldown).

Make sure we use \< and \> in markdown all over so that it renders
correctly, on GitHub and elsewhere. cd2nroff now outputs a warning if it
finds an unescaled angle bracket.
Ref: #12854Closes#12869
curldown is this new file format for libcurl man pages. It is markdown
inspired with differences:
- Each file has a set of leading headers with meta-data
- Supports a small subset of markdown
- Uses .md file extensions for editors/IDE/GitHub to treat them nicely
- Generates man pages very similar to the previous ones
- Generates man pages that still convert nicely to HTML on the website
- Detects and highlights mentions of curl symbols automatically (when
their man page section is specified)
tools:
- cd2nroff: converts from curldown to nroff man page
- nroff2cd: convert an (old) nroff man page to curldown
- cdall: convert many nroff pages to curldown versions
- cd2cd: verifies and updates a curldown to latest curldown
This setup generates .3 versions of all the curldown versions at build time.
CI:
Since the documentation is now technically markdown in the eyes of many
things, the CI runs many more tests and checks on this documentation,
including proselint, link checkers and tests that make sure we capitalize the
first letter after a period...
Closes#12730
