- librtmp has no test cases, makes no proper releases and has not had a
single commit within the last year

survey)
Closes#20673
Replace the `volatile int dirty` with a reference counter
protected by a mutex when available.
Solve the problem of when to call application's lock function
by adding a volatile flag that indicates a share has been added
to easy handles in its lifetime. That flag ever goes from
FALSE to TRUE, so volatile might work (in the absence of a mutex).
(The problem is that the lock/unlock functions need 2-3
`curl_share_setopt()` invocations to become usable and there
is no way of telling if the third will ever happen. Calling
the lock function before the 3rd setopt may crash the
application.)
When removing a share from an easy handle (or replacing it with
another share), detach the easy connection on a share with a
connection pool.
When cleaning up a share, allow this even if it is still used in
easy handles. It will be destroyed when the reference count
drops to 0.
Closes#20870
The extra % translates to nothing, so this did not break anything they
are just superfluous.

It's mostly a filler word. I've read through each use of it in the code
base and did minor rephrasings when "simply" carried some meaning. The
overwhelming majority of cases, removing it improved the text
significantly. Inspired by #20793.
Closes#20822
- vms/curlmsg_vms.h: delete unused/commented code.
- vtls/schannel_verify: sort includes.
- typecheck-gcc.h: fix indent and alignment.
- lib/config-win32.h: drop idle `#undef`.
- spacecheck: check for stray empty lines before after curly braces.
- make literals more readable: 1048576 -> 1024 * 1024
- scope variables.
- use ISO date in a comment.
- drop redundant parentheses.
- drop empty comments.
- unfold lines.
- duplicate/stray spaces in comments.
- fix indent, whitespace, minor typos.
Closes#20690
Backtrack on previous change that aimed to solve the wrong `share.h`
being included. It turns out it did not fix this issue. At the same time
it introduced relative header filenames and the need to include the same
headers differently depending on the source files' location, reducing
readability and editability.
Replace this method by re-adding curl's lib source directory to the
header path and addressing headers by the their full, relative name to
that base directory. Aligning with this method already used in src and
tests.
With these advantages:
- makes includes easier to read, recognize, grep, sort, write, and copy
between sources,
- syncs the way these headers are included across curl components,
- avoids the ambiguity between system `schannel.h`, `rustls.h` vs.
local headers using the same names in `lib/vtls`,
- silences clang-tidy `readability-duplicate-include` checker, which
detects the above issue,
Ref: https://clang.llvm.org/extra/clang-tidy/checks/readability/duplicate-include.html
- possibly silences TIOBE coding standard warnings:
`6.10.2.a: Don't use relative paths in #include statements.`
- long shot: it works well with concatenated test sources, for
clang-tidy-friendly custom unity builds. Ref: #20667
Slight downside: it's not enforced.
If there happens to be a collision between a local `lib/*.h` header and
a system one, the solution is to rename (possibly with its `.c`
counterpart) into the `curl_` namespace. This is also the method used by
curl in the past.
Also:
- curlx/inet_pton: reduce scope of an include.
- toolx/tool_time: apply this to an include, and update VS project
files accordingly. Also dropping unnecessary lib/curlx header path.
- clang-tidy: enable `readability-duplicate-include`.

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.

After this patch curl requires targeting Vista or newer, and a toolchain
with Vista support.
Supported MSVC compilers (VS2010+) all support Vista:
- VS2012+ target Win8 (or later) by default.
- VS2010 targets Win7 by default.
Supported mingw-w64 versions (v3+) all support Vista:
- mingw-w64 v9+ target Win10 by default.
- mingw-w64 v8 and older target Server 2003 (~XP) by default.
After this patch it may be necessary to override the default Windows
target version to Vista (or newer) via:
autotools: `CPPFLAGS=-D_WIN32_WINNT=0x0600`
cmake: `-DCURL_TARGET_WINDOWS_VERSION=0x0600`
- mingw-w64 v6+ allow changing the default at toolchain build-time.
Notes:
- For non-MSVC, non-mingw-w64 toolchains, `if_nametoindex` needs to be
allowlisted in `curl_setup.h`, if they do support it.
Fixes#17985 (discussion)
Closes#18009
To simplify the directory layout.
- OS400 and vms support move from `packages` to `projects`.
- Windows README and `generate.bat` files move from `projects`
to `projects/Windows`.
Closes#20271
- Fix generate.bat "-clean" option.
- Change version template substitutes to match old files, eg go back to
using format version "11.00" instead of "11.0".
- Limit the vcxproj filters file types that are filtered to c, h, rc.
- Get rid of the tmpl extension from template files and add a README
to the tmpl directory explaining the purpose of the files.
- gitignore VCxx directories entirely rather than individual file types.
- Do not remove the VC directories during clean, instead remove just the
generated project files.
Removing the VC directories has the unwanted behavior of removing files
other than those generated. Visual Studio will generate its own
preference files (like if you have some debug arguments in your .suo)
and those files sit in the VC directories. We ignore those files since
they are the user's files and should not be deleted. Also the user may
have their own untracked files that we shouldn't be deleting.

Closes https://github.com/curl/curl/pull/18412
The three projects (VC10, VC11, VC12) are identical except 5 repeated
strings in them. They also require running `generate.bat` before use,
to populate source files. Reduce the 3 almost identical projects to
a single template project and populate the repeated strings also via
`generate.bat`. This reduces the maintenance burden to a single copy of
the project files. Also saving 10000 LOCs.

Move curlx_ functions into its own subdir.
The idea is to use the curlx_ prefix proper on these functions, and use
these same function names both in tool, lib and test suite source code.
Stop the previous special #define setup for curlx_ names.
The printf defines are now done for the library alone. Tests no longer
use the printf defines. The tool code sets its own defines. The printf
functions are not curlx, they are publicly available.
The strcase defines are not curlx_ functions and should not be used by
tool or server code.
dynbuf, warnless, base64, strparse, timeval, timediff are now proper
curlx functions.
When libcurl is built statically, the functions from the library can be
used as-is. The key is then that the functions must work as-is, without
having to be recompiled for use in tool/tests. This avoids symbol
collisions - when libcurl is built statically, we use those functions
directly when building the tool/tests. When libcurl is shared, we
build/link them separately for the tool/tests.

Closes#17253
- Do not include curlinfo.c as a ClCompile unit when compiling the curl
tool.
Prior to this change generate.bat would add curlinfo.c to the source
files for the curl tool because it is located in the src directory. That
caused ambiguous behavior in legacy versions of Visual Studio which had
to guess between two main entry points (one in curlinfo and one in
tool_main, the latter being correct).
Closes https://github.com/curl/curl/pull/17263
The curl tool and tests/server used 2 parallel implementations
of libcurl's `Curl_now()` and `Curl_timediff()` functions.
Make them use the libcurl one.
Closes#16653
- VS projects: drop unused `timediff`.
(used by curltool library, but this build method doesn't build that.)
- tests/server/sws: reflow an `if` for greppability.
- tests/server/Makefile.inc: indent, format
- tests/server/Makefile.inc: merge `USEFUL` and `UTIL` lists.
Closes#16651
- add hex and octal parsers to the Curl_str_* family
- make curlx_strtoofft use these parsers
- remove all use of strtol() and strtoul() in library code
- generally use Curl_str_* more than strtoofft, for stricter parsing
- supports 64-bit universally, instead of 'long' which differs in size
between platforms
Extended the unit test 1664 to verify hex and octal parsing.
Closes#16336
- Remove the command line argument passed to checksrc.pl that accepts
SNPRINTF violations in docs/examples.

- Remove wolfSSL from the legacy projects for Visual Studio 2010 - 2013.
It's no longer possible to maintain the custom build configuration of
wolfSSL for these old versions of Visual Studio.

in 4de627ab and the user could possibly make their own wolfSSL build and
attempt to link it using an old version of Visual Studio that way.

Add the ability to embed a CA bundle into the curl binary. It is used
when no other runtime or build-time option set one.
This helps curl-for-win macOS and Linux builds to run standalone, and
also helps Windows builds to avoid picking up the CA bundle from an
arbitrary (possibly world-writable) location (though this behaviour is
not currently disablable).
Usage:
- cmake: `-DCURL_CA_EMBED=/path/to/curl-ca-bundle.crt`
- autotools: `--with-ca-embed=/path/to/curl-ca-bundle.crt`
- Makefile.mk: `CURL_CA_EMBED=/path/to/curl-ca-bundle.crt`
Also add new command-line option `--dump-ca-embed` to dump the embedded
CA bundle to standard output.
