Closes#9635
This patch overhauls `Makefile.m32` scripts, fixing a list of quirks,
making its behaviour and customization envvars align better with other
build systems, aiming for less code, that is easier to read, use and
maintain.
Details:
- Rename customization envvars:
`CURL_CC` -> `CC`
`CURL_RC` -> `RC`
`CURL_AR` -> `AR`
`CURL_LDFLAG_EXTRAS_DLL` -> `CURL_LDFLAGS_LIB`
`CURL_LDFLAG_EXTRAS_EXE` -> `CURL_LDFLAGS_BIN`
- Drop `CURL_STRIP` and `CURL_RANLIB`. These tools are no longer used.
- Accept `CFLAGS`, `CPPFLAGS`, `RCFLAGS`, `LDFLAGS` and `LIBS` envvars.
- Drop `CURL_CFLAG_EXTRAS`, `CURL_LDFLAG_EXTRAS`, `CURL_RCFLAG_EXTRAS` in
favor of the above.
- Do not automatically enable `zlib` with `libssh2`. `zlib` is optional
with `libssh2`.
- Omit unnecessary `CPPFLAGS` options when building `curl.exe` and
examples.
- Drop support for deprecated `-winssl` `CFG` option. Use `-schannel`
instead.
- Avoid late evaluation where not necessary (`=` -> `:=`).
- Drop support for `CURL_DLL_A_SUFFIX` to override the implib suffix.
Instead, use the standard naming scheme by default: `libcurl.dll.a`.
The toolchain recognizes the name, and selects it automatically when
asking for a `-shared` vs. `-static` build.
- Stop applying `strip` to `libcurl.a`. Follow-up from
16a58e9f93. There was no debug info to
strip since then.
- Stop setting `-O3`, `-W`, `-Wall` options. You can add these to
`CFLAGS` as desired.
- Always enable `-DCURL_DISABLE_OPENSSL_AUTO_LOAD_CONFIG` with OpenSSL,
to avoid that vulnerability on Windows.
- Add `-lbrotlicommon` to `LIBS` when using `brotli`.
- Do not enable `-nghttp3` without `-ngtcp2`.
- `-ssh2` and `-rtmp` options no longer try to auto-select a TLS-backend.
You need to set the backend explicitly. This scales better and avoids
issues with certain combinations (e.g. `libssh2` + `wolfssl` with no
`schannel`).
- Default to OpenSSL TLS-backend with `ngtcp2`. Possible to override via
`NGTCP2_LIBS`.
- Old, alternate method of enabling components (e.g. `SSH2=1`) no longer
supported.
- Delete `SPNEGO` references. They were no-ops.
- Drop support for Win9x environments.
- Allow setting `OPENSSL_LIBS` independently from `OPENSSL_LIBPATH`.
- Support autotools/CMake `libssh2` builds by default.
- Respect `CURL_DLL_SUFFIX` in `-dyn` mode when building `curl.exe` and
examples.
- Assume standard directory layout with `LIBCARES_PATH`. (Instead of the
long gone embedded one.)
- Stop static linking with c-ares by default. Add
`CPPFLAGS=-DCARES_STATICLIB` to enable it.
- Reorganize internal layout to avoid redundancy and emit clean diffs
between src/lib and example make files.
- Delete unused variables.
- Code cleanups/rework.
- Comment and indentation fixes.
Closes#9632
- Drop auto-detection of OpenSSL 1.0.2 and earlier. Now always defaulting
to OpenSSL 1.1.0 and later, LibreSSL and BoringSSL.
- Drop `Invalid path to OpenSSL package` detection. OpenSSL has been
using a standard file layout since 1.1.0, so this seems unnecessary
now.
- Drop special logic to enable Novell LDAP SDK support.
- Drop special logic to enable OpenLDAP LDAP SDK support. This seems
to be distinct from native OpenLDAP, with support implemented inside
`lib/ldap.c` (vs. `lib/openldap.c`) back when the latter did not exist
yet in curl.
- Add `-lwldap32` only if there is no other LDAP library (either native
OpenLDAP, or SDKs above) present.
- Update `doc/INSTALL.md` accordingly.
After this patch, it's necessary to make configration changes when using
OpenSSL 1.0.2 or earlier, or the two LDAP SDKs.
OpenSSL 1.0.2 and earlier:
```
export OPENSSL_INCLUDE = <path-to-openssl>/outinc
export OPENSSL_LIBPATH = <path-to-openssl>/out
export OPENSSL_LIBS = -lssl32 -leay32 -lgdi32
```
Novell LDAP SDK, previously enabled via `USE_LDAP_NOVELL=1`:
```
export CURL_CFLAG_EXTRAS = -I<path-to-sdk>/inc -DCURL_HAS_NOVELL_LDAPSDK
export CURL_LDFLAG_EXTRAS = -L<path-to-sdk>/lib/mscvc -lldapsdk -lldapssl -lldapx
```
OpenLDAP LDAP SDK, previously enabled via `USE_LDAP_OPENLDAP=1`:
```
export CURL_CFLAG_EXTRAS = -I<path-to-sdk>/include -DCURL_HAS_OPENLDAP_LDAPSDK
export CURL_LDFLAG_EXTRAS = -L<path-to-sdk>/lib -lldap -llber
```
I haven't tested these scenarios, and in general we recommend using
a recent OpenSSL release. Also, WinLDAP (the Windows default) and
OpenLDAP (via `-DUSE_OPENLDAP`) are the LDAP options actively worked on
in curl.
Closes#9631
SourceForge projects can now choose between two hostnames, with .io and
.net ending. Both support HTTPS by default now. Opening the other variant
will perm-redirected to the one chosen by the project.
The .io -> .net redirection is done insecurely.
Let's update the URLs to point to the current canonical endpoints to
avoid any redirects.
Closes#9630
- Add `-lcrypt32` once, and add it always for simplicity.
- Delete broken link and reference to the pre-Vista WinIDN add-on.
MS no longer distribute it.
- Delete related `WINIDN_PATH` option. IDN is a system lib since Vista.
- Sync `LIBCARES_PATH` default with the rest of dependencies.
- Delete version numbers from dependency path defaults.
- `libgsasl` package is now called `gsasl`.
- Delete `libexpat` and `libxml2` references. No longer used by curl.
- Delete `Edit the path below...` comments. We recommend to predefine
those envvars instead.
- `libcares.a` is not an internal dependency anymore. Stop using it as
such.
- `windres` `--include-dir` -> `-I`, `-F` -> `--target=` for readability.
- Delete `STRIP`, `CURL_STRIP`, `AR` references from `src/Makefile.m32`.
They were never used.
- Stop to `clean` some objects twice in `src/Makefile.m32`.
- Delete cvs-specific leftovers.
- Finish resource support in examples make file.
- Delete `-I<root>/lib` from examples make file.
- Fix copyright start year in examples make file.
- Delete duplicate `ftpuploadresume` input in examples make file.
- Sync OpenSSL lib order, `SYNC` support, `PROOT` use, dependency path
defaults, variables names and other internal bits between the three
make files.
- `lib/Makefile.m32` accepted custom options via `DLL_LIBS` envvar. This
was lib-specific and possibly accidental. Use `CURL_LDFLAG_EXTRAS_DLL`
envvar for the same effect.
- Fix linking `curl.exe` and examples to wrong static libs with
auto-detected OpenSSL 1.0.2 or earlier.
- Add `-lgdi32` for OpenSSL 1.0.2 and earlier only.
- Add link to Novell LDAP SDK and use a relative default path. Latest
version is from 2016, linked to an outdated OpenSSL 1.0.1.
- Whitespace and comment cleanups.
TODO in a next commit:
Delete built-in detection/logic for OpenSSL 1.0.2 and earlier, the Novell
LDAP SDK and the other LDAP SDK (which is _not_ OpenLDAP). Write up the
necessary custom envvars to configure them.
Closes#9616
Added in 68b215157f, while adding openldap
support. This is also the single mention of this constant in the source

The introduction of CURL_DISABLE_MIME came with some additional bugs:
- Disabled MIME is compiled-in anyway if SMTP and/or IMAP is enabled.
- CURLOPT_MIMEPOST, CURLOPT_MIME_OPTIONS and CURLOPT_HTTPHEADER are
conditioned on HTTP, although also needed for SMTP and IMAP MIME mail
uploads.
In addition, the CURLOPT_HTTPHEADER and --header documentation does not
mention their use for MIME mail.
This commit fixes the problems above.
Closes#9610
The existing code tried but did not properly reject alternative services
using negative or too large port numbers.
With this fix, the logic now also flushes the old entries immediately
before adding a new one, making a following header with an illegal entry
not flush the already stored entry.

Adjusted test 356 to verify.

This header is for providing the argument types for recv() and send()
when built to not use a dedicated config-[platfor].h file.
Remove the slow brute-force checks from configure and cmake.
This change also removes the use of the types for select, as they were
not used in code.
Closes#9592
If curl_off_t turns out to be smaller than 8 bytes,
--with-n64-deprecated needs to be used to allow the build to
continue. This is to highlight the fact that support for such builds is
going away next year.

Closes#9605
This function is currently located in the lib/http.c module and is
therefore disabled by the CURL_DISABLE_HTTP conditional token.
As it may be called by TLS backends, disabling HTTP results in an
undefined reference error at link time.
Move this function to vauth/vauth.c to always provide it and rename it
as Curl_auth_allowed_to_host() to respect the vauth module naming
convention.
Closes#9600
Curl_ossl_certchain() is now an exported function in lib/vtls/openssl.c that
can also be used from quiche.c and ngtcp2.c to get the cert chain for QUIC
connections as well.
The *certchain function was moved to the top of the file for this reason.

This local autotools logic was put in place in
9e24b9c7af (in 2012) which disabled it for
Windows unconditionally. Testing reveals that it actually works with
tested toolchains (mingw-w64 and CI ones), so let's allow this build
feature on that platform. Bringing this in sync with CMake, which already
supported this.

Closes#9586
autotools uses brute-force to detect `recv`/`send`/`select` argument
lists, by interating through _all_ argument type combinations on each
`./configure` run. This logic exists since
01fa02d0b5 (from 2006) and was a bit later
extended with Windows support.
This results in a worst-case number of compile + link cycles as below:
- `recv`: 96
- `send`: 192
- `select`: 60
Total: 348 (the number of curl C source files is 195, for comparison)
Notice that e.g. curl-for-win autotools builds require two `./configure`
invocations, doubling these numbers.
`recv` on Windows was especially unlucky because `SOCKET` (the correct
choice there) was listed _last_ in one of the outer trial loops. This
resulted in lengthy waits while autotools was trying all invalid
combinations first, wasting cycles, disk writes and slowing down
iteration.
This patch reduces the amount of idle work by reordering the tests in
a way to succeed first on a well-known platform such as Windows, and
also on non-Windows by testing for POSIX prototypes first, on the
assumption that these are the most likely candidates these days. (We do
not touch `select`, where the order was already optimal for these
platforms.)
For non-Windows, this means to try a return value of `ssize_t` first,
then `int`, reordering the buffer argument type to try `void *` first,
then `byte *`, and prefer the `const` flavor with `send`. If we are
here, also stop testing for `SOCKET` type in non-Windows builds.
After the patch, detection on Windows is instantaneous. It should also be
faster on popular platforms such as Linux and BSD-based ones.
If there are known-good variations for other platforms, they can also be
fast-tracked like above, given a way to check for that platform inside
the autotools logic.

This is the single place in libcurl code where it uses the "native"
s(n)printf() function. Used for writing floats. The use has been
reviewed and vetted and uses a HUGE target buffer, but switching to
snprintf() still makes this safer and removes build-time warnings.
