It could previously be set with configure/cmake and used in rare cases
for reading randomness: with ancient mbedTLS or rustls without
arc4random.
We now get randomness in this order:
1. The TLS library's way to provide random
2. On Windows: Curl_win32_random
3. if arc4random exists, use that
4. weak non-crytographically strong pseudo-random
Closes#14749
- `HAVE_LIBSSH2`: unused in source. Not defined in CMake.
- `HAVE_LIBSOCKET`: unused in source. Used internally in CMake.
autotools sets them implicitly, so add them to the flag comparison
ignore-list.
Closes#14178
Before this patch `lib/curl_setup.h` defined these two macros right
next to each other, then the source code used them interchangeably.
After this patch, `USE_HTTP3` guards all HTTP/3 / QUIC features.
(Like `USE_HTTP2` does for HTTP/2.) `ENABLE_QUIC` is no longer used.
This patch doesn't change the way HTTP/3 is enabled via autotools
or CMake. Builders who enabled HTTP/3 manually by defining both of
these macros via `CPPFLAGS` can now delete `-DENABLE_QUIC`.
Closes#13352
Before this patch, two macros were used to guard IPv6 features in curl
sources: `ENABLE_IPV6` and `USE_IPV6`. This patch makes the source use
the latter for consistency with other similar switches.
`-DENABLE_IPV6` remains accepted for compatibility as a synonym for
`-DUSE_IPV6`, when passed to the compiler.
`ENABLE_IPV6` also remains the name of the CMake and `Makefile.vc`
options to control this feature.
Closes#13349
Stop setting `HAVE_GSSHEIMDAL`, `HAVE_GSSMIT` and `HAVE_HEIMDAL`.
There was no place in the build system or source code that used them.

Closes#12506
We use `stdint.h` unconditionally in all places except one. These uses
are imposed by external dependencies / features. nghttp2, quic, wolfSSL
and `HAVE_MACH_ABSOLUTE_TIME` do require this C99 header. It means that
any of these features make curl require a C99 compiler. (In case of
MSVC, this means Visual Studio 2010 or newer.)
This patch changes the single use of `stdint.h` guarded by
`HAVE_STDINT_H` to use `stdint.h` unconditionally. Also stop using
`inttypes.h` as an alternative there. `HAVE_INTTYPES_H` wasn't used
anywhere else, allowing to delete this feature check as well.
Closes#12275
Delete checks and guards for standard C89 headers and assume these are
available: `stdio.h`, `string.h`, `time.h`, `setjmp.h`, `stdlib.h`,
`stddef.h`, `signal.h`.
Some of these we already used unconditionally, some others we only used
for feature checks.
Follow-up to 9c7165e96a#11918 (for `stdio.h` in CMake)
Closes#11940
We remove support for building curl with gskit.
- This is a niche TLS library, only running on some IBM systems
- no regular curl contributors use this backend
- no CI builds use or verify this backend
- gskit, or the curl adaption for it, lacks many modern TLS features
making it an inferior solution
- build breakages in this code take weeks or more to get detected
- fixing gskit code is mostly done "flying blind"
This removal has been advertized in DEPRECATED in Jan 2, 2023 and it has
been mentioned on the curl-library mailing list.
It could be brought back, this is not a ban. Given proper effort and
will, gskit support is welcome back into the curl TLS backend family.
Closes#11460
- cache more Windows config results for faster initialization.
- delete unused config macros `HAVE_SYS_UTSNAME_H`, `HAVE_SSL_H`.
- delete dead references to `sys/utsname.h`.
Closes#11551
EGD is Entropy Gathering Daemon, a socket-based entropy source supported
by pre-OpenSSL v1.1 versions and now deprecated. curl also deprecated it
a while ago.
Its detection in CMake was broken all along because OpenSSL libs were
not linked at the point of feature check.
Delete detection from both cmake and autotools, along with the related
source snippet, and the `--with-egd-socket=` `./configure` option.
Closes#11556
- they are mostly pointless in all major jurisdictions
- many big corporations and projects already don't use them
- saves us from pointless churn
- git keeps history for us
- the year range is kept in COPYING
checksrc is updated to allow non-year using copyright statements
Closes#10205
Update bare GNU Make `Makefile.m32` to:
- Move objects into a subdirectory.
- Add support for MS-DOS. Tested with DJGPP.
- Add support for Watt-32 (on MS-DOS).
- Add support for AmigaOS.
- Rename `Makefile.m32` to `Makefile.mk`
- Replace `ARCH` with `TRIPLET`.
- Build `tool_hugehelp.c` proper (when tools are available).
- Drop MS-DOS compatibility macro `USE_ZLIB` (replaced by `HAVE_LIBZ`)
- Add support for `ZLIB_LIBS` to override `-lz`.
- Omit object files when building examples.
- Default `CC` to `gcc` once again, for convenience. (Caveat: compiler
name `cc` cannot be set now.)
- Set `-DCURL_NO_OLDIES` for examples, like autotools does.
- Delete `makefile.dj` files. Notice the configuration details and
defaults are not retained with the new method.
- Delete `makefile.amiga` files. A successful build needs a few custom
options. We're also not retaining all build details from the existing
Amiga make files.
- Rename `Makefile.m32` to `Makefile.mk` to reflect that they are not
Windows/MinGW32-specific anymore.
- Add support for new `CFG` options: `-map`, `-debug`, `-trackmem`
- Set `-DNDEBUG` by default.
- Allow using `-DOS=...` in all `lib/config-*.h` headers, syncing this
with `config-win32.h`.
- Look for zlib parts in `ZLIB_PATH/include` and `ZLIB_PATH/lib`
instead of bare `ZLIB_PATH`.
Note that existing build configurations for MS-DOS and AmigaOS likely
become incompatible with this change.
Example AmigaOS configuration:
```
export CROSSPREFIX=/opt/amiga/bin/m68k-amigaos-
export CC=gcc
export CPPFLAGS='-DHAVE_PROTO_BSDSOCKET_H'
export CFLAGS='-mcrt=clib2'
export LDFLAGS="${CFLAGS}"
export LIBS='-lnet -lm'
make -C lib -f Makefile.mk
make -C src -f Makefile.mk
```
Example MS-DOS configuration:
```
export CROSSPREFIX=/opt/djgpp/bin/i586-pc-msdosdjgpp-
export WATT_PATH=/opt/djgpp/net/watt
export ZLIB_PATH=/opt/djgpp
export OPENSSL_PATH=/opt/djgpp
export OPENSSL_LIBS='-lssl -lcrypt'
export CFG=-zlib-ssl
make -C lib -f Makefile.mk
make -C src -f Makefile.mk
```

Add licensing and copyright information for all files in this repository. This
either happens in the file itself as a comment header or in the file
`.reuse/dep5`.
This commit also adds a Github workflow to check pull requests and adapts
copyright.pl to the changes.

... as they're checked for in the configure script and are used by
source code.
Removed checks for perror, setvbuf and strlcat since those defines are
not checked for in source code.
Bonus: removed HAVE_STRLCPY from a few config-*.h files since that
symbol is not used in source code.
Closes#6997
This was previously defined by the obsolete AC_TYPE_SIGNAL macro,
which was removed in 2682e5f5. The deprecation text says
> Your code may safely assume C89 semantics that RETSIGTYPE is void.
So, remove it and just use void instead.
