Daniel Stenberg (21 Dec 2022)

- RELEASE-NOTES: synced

The curl 7.87.0 release

- THANKS: 40 new contributors from 7.87.0

- http: fix the ::1 comparison for IPv6 localhost for cookies

When checking if there is a "secure context", which it is if the
  connection is to localhost even if the protocol is HTTP, the comparison
  for ::1 was done incorrectly and included brackets.

- x509asn1: avoid freeing unallocated pointers

When utf8asn1str fails there is no allocation returned, so freeing
  the return pointer in **to is at best a no-op and at worst a double-
  free bug waiting to happen. The current coding isn't hiding any such
  bugs but to future proof, avoid freeing the return value pointer iff
  the function failed.

Closes #10064

Daniel Stenberg (9 Dec 2022)

- KNOWN_BUGS: remove items not considered bugs any more

- CURL_GLOBAL_SSL

This option was changed in libcurl 7.57.0 and clearly it has not caused
  too many issues and a lot of time has passed.

- Store TLS context per transfer instead of per connection

This is a possible future optimization. One that is much less important
  and interesting since the added support for CA caching.

- Microsoft telnet server

This bug was filed in May 2007 against curl 7.16.1 and we have not
  received further reports.

- active FTP over a SOCKS

Actually, proxies in general is not working with active FTP mode. This
  is now added in proxy documentation.

- DICT responses show the underlying protocol

curl still does this, but since this is now an established behavior
  since forever we cannot change it easily and adding an option for it
  seems crazy as this protocol is not so little its not worth it. Let's
  just live with it.

- Secure Transport disabling hostname validation also disables SNI

This is an already documented restriction in Secure Transport.

- CURLOPT_SEEKFUNCTION not called with CURLFORM_STREAM

The curl_formadd() function is marked and documented as deprecated. No
  point in collecting bugs for it. It should not be used further.

- STARTTRANSFER time is wrong for HTTP POSTs

After close source code inspection I cannot see how this is true or that
  there is any special treatment for different HTTP methods. We also have
  not received many further reports on this, making me strongly suspect
  that this is no (longer an) issue.

- multipart formposts file name encoding

The once proposed RFC 5987-encoding is since RFC 7578 documented as MUST
  NOT be used. The since then implemented MIME API allows the user to set
  the name on their own and can thus provide it encoded as it wants.

- DoH is not used for all name resolves when enabled

It is questionable if users actually want to use DoH for interface and
  FTP port name resolving. This restriction is now documented and we
  advice users against using name resolving at all for these functions.

- system.h: fix socklen_t, curl_off_t, long long for Classic Mac OS

Change "__MWERKS__" to "macintosh". When this block was originally added
  in 3ac6929 it was probably intended to handle classic Mac OS since the
  previous classic Mac OS build procedure for curl (which was removed in
  bf327a9) used Metrowerks CodeWarrior.

But there are other classic Mac OS compilers, such as the MPW compilers,
  that were not handled by this case. For classic Mac OS,
  CURL_TYPEOF_CURL_SOCKLEN_T needs to match what's provided by the
  third-party GUSI library, which does not vary by compiler.

Meanwhile CodeWarrior works on platforms other than classic Mac OS, and
  they may need different definitions. Separate blocks could be added
  later for any of those platforms that curl doesn't already support.

Daniel Gustafsson (8 Dec 2022)

- tool_formparse: avoid clobbering on function params

While perfectly legal to do, clobbering function parameters and using
  them as local variables is confusing at best and rarely improves code
  readability.  Fix by using a local variable instead, no functionality
  is changed.

This also renames the parameter from data to mime_data since the term
  data is (soft) reserved for the easy handle struct.

Partially reverts "somewhat protect Mac OS X users from using Mac OS 9

Do things that are specific to classic Mac OS (i.e. include config-mac.h
  in curl_setup.h and rename "main" to "curl_main" in tool_setup.h) when
  only "macintosh" is defined. Remove the additional condition that
  "__MRC__" should be defined since that would only be true with the MPW
  MrC compiler which prevents the use of other reasonable compilers like
  the MPW SC compiler and especially the Metrowerks CodeWarrior compilers.
  "macintosh" is only defined by classic Mac OS compilers so this change
  should not affect users of Mac OS X / OS X / macOS / any other OS.

- Initialize user-customizable variables:

- mime: relax easy/mime structures binding

Deprecation and removal of codeset conversion support from the library
  have released the strict need for an early binding of mime structures to
  an easy handle (https://github.com/curl/curl/commit/2610142).

This constraint currently forces to create the handle before the mime
  structure and the latter cannot be attached to another handle once
  created (see https://curl.se/mail/lib-2022-08/0027.html).

This commit removes the handle pointers from the mime structures
  allowing more flexibility on their use.

When an easy handle is duplicated, bound mime structures must however
  still be duplicated too as their components hold send-time dynamic
  information.

- ftp: support growing files with CURLOPT_IGNORE_CONTENT_LENGTH

When using the option CURLOPT_IGNORE_CONTENT_LENGTH (set.ignorecl in
  code) to support growing files in FTP, the code should ignore the
  initial size it gets from the server as this will not be the final size
  of the file. This is done in ftp_state_quote() to prevent a size request
  being issued in the initial sequence. However, in a later call to
  ftp_state_get_resp() the code attempts to get the size of the content
  again if it doesn't already have it, by parsing the response from the
  RETR request. This fix prevents this parsing of the response to get the
  size when the set.ignorecl option is set. This should maintain the size
  value as -1, unknown, in this situation.

This makes a big difference for cases when the rewind is not actually

  when that rewind fails, for example when reading from a pipe or similar.

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`

  - 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

- sendf: change Curl_read_plain to wrap Curl_recv_plain (take 2)

Prior to this change Curl_read_plain would attempt to read the
  socket directly. On Windows that's a problem because recv data may be
  cached by libcurl and that data is only drained using Curl_recv_plain.

Rather than rewrite Curl_read_plain to handle cached recv data, I
  changed it to wrap Curl_recv_plain, in much the same way that
  Curl_write_plain already wraps Curl_send_plain.

Curl_read_plain -> Curl_recv_plain
  Curl_write_plain -> Curl_send_plain

This fixes a bug in the schannel backend where decryption of arbitrary
  TLS records fails because cached recv data is never drained. We send
  data (TLS records formed by Schannel) using Curl_write_plain, which
  calls Curl_send_plain, and that may do a recv-before-send
  ("pre-receive") to cache received data. The code calls Curl_read_plain
  to read data (TLS records from the server), which prior to this change
  did not call Curl_recv_plain and therefore cached recv data wasn't
  retrieved, resulting in malformed TLS records and decryption failure
  (SEC_E_DECRYPT_FAILURE).

The bug has only been observed during Schannel TLS 1.3 handshakes. Refer
  to the issue and PR for more information.

This is take 2 of the original fix. It preserves the original behavior
  of Curl_read_plain to write 0 to the bytes read parameter on error,
  since apparently some callers expect that (SOCKS tests were hanging).
  The original fix which landed in 12e1def5 and was later reverted in
  18383fbf failed to work properly because it did not do that.

Also, it changes Curl_write_plain the same way to complement
  Curl_read_plain, and it changes Curl_send_plain to return -1 instead of
  0 on CURLE_AGAIN to complement Curl_recv_plain.

Behavior on error with these changes:

Curl_recv_plain returns -1 and *code receives error code.
  Curl_send_plain returns -1 and *code receives error code.
  Curl_read_plain returns error code and *n (bytes read) receives 0.
  Curl_write_plain returns error code and *written receives 0.

  from the number of bytes (nmemb) passed to the callback. Also, the
  inclination of some users has been to just return 0 to signal error,
  which is incorrect as that may be the number of bytes passed to the
  callback.

To remedy this the user can now return CURL_WRITEFUNC_ERROR instead.

This option adds a piece of data, usually a name + value pair, to the

- lib: sync guard for Curl_getaddrinfo_ex() definition and use

`Curl_getaddrinfo_ex()` gets _defined_ with `HAVE_GETADDRINFO` set. But,
  `hostip4.c` _used_ it with `HAVE_GETADDRINFO_THREADSAFE` set alone. It
  meant a build with the latter, but without the former flag could result
  in calling this function but not defining it, and failing to link.

Patch this by adding an extra check for `HAVE_GETATTRINFO` around the
  call.

Before this patch, build systems prevented this condition. Now they
  don't need to.

While here, simplify the related CMake logic on Windows by setting
  `HAVE_GETADDRINFO_THREADSAFE` to the detection result of
  `HAVE_GETADDRINFO`. This expresses the following intent clearer than
  the previous patch and keeps the logic in a single block of code:
  When we have `getaddrinfo()` on Windows, it's always threadsafe.

- tidy-up: process.h detection and use

This patch aims to cleanup the use of `process.h` header and the macro
  `HAVE_PROCESS_H` associated with it.

- `process.h` is always available on Windows. In curl, it is required
    only for `_beginthreadex()` in `lib/curl_threads.c`.

- `process.h` is also available in MS-DOS. In curl, its only use was in
    `lib/smb.c` for `getpid()`. But `getpid()` is in fact declared by
    `unistd.h`, which is always enabled via `lib/config-dos.h`. So the
    header is not necessary.

- `HAVE_PROCESS_H` was detected by CMake, forced to 1 on Windows and
    left to real detection for other platforms.
    It was also set to always-on in `lib/config-win32.h` and
    `lib/config-dos.h`.
    In autotools builds, there was no detection and the macro was never
    set.

Based on these observations, in this patch we:

- Rework Windows `getpid` logic in `lib/smb.c` to always use the
    equivalent direct Win32 API function `GetCurrentProcessId()`, as we
    already did for Windows UWP apps. This makes `process.h` unnecessary
    here on Windows.

- Stop #including `process.h` into files where it was not necessary.
    This is everywhere, except `lib/curl_threads.c`.

> Strangely enough, `lib/curl_threads.c` compiled fine with autotools
    > because `process.h` is also indirecty included via `unistd.h`. This
    > might have been broken in autotools MSVC builds, where the latter
    > header is missing.

- Delete all remaining `HAVE_PROCESS_H` feature guards, for they were
    unnecessary.

- Delete `HAVE_PROCESS_H` detection from CMake and predefined values
    from `lib/config-*.h` headers.

- windows: fix linking .rc to shared curl with autotools

`./configure --enable-shared --disable-static` fails when trying to link
  a shared `curl.exe`, due to `libtool` magically changing the output
  filename of `windres` to one that it doesn't find when linking:

```
  /bin/sh ../libtool --tag=RC --mode=compile windres -I../../curl/include -DCUR
  L_EMBED_MANIFEST  -i ../../curl/src/curl.rc -o curl.o
  libtool: compile:  windres -I../../curl/include -DCURL_EMBED_MANIFEST -i ../.
  ./curl/src/curl.rc  -o .libs/curl.o
  [...]
  CCLD     curl.exe
  clang: error: no such file or directory: 'curl.o'
  ```

Let's resolve this by skipping `libtool` and calling `windres` directly
  when building `src` (aka `curl.exe`). Leave `lib` unchanged, as it does
  need the `libtool` magic. This solution is compatible with building
  a static `curl.exe`.

This build scenario is not CI-tested.

While here, delete an obsolete comment about a permanent `libtool`
  warning that we've resolved earlier.

- cmake: really enable warnings with clang

Even though `PICKY_COMPILER=ON` is the default, warnings were not
  enabled when using llvm/clang, because `CMAKE_COMPILER_IS_CLANG` was
  always false (in my tests at least).

This is the single use of this variable in curl, and in a different
  place we already use `CMAKE_C_COMPILER_ID MATCHES "Clang"`, which works
  as expected, so change the condition to use that instead.

Also fix the warnings uncovered by the above:

- lib: add casts to silence clang warnings

- schannel: add casts to silence clang warnings in ALPN code

Assuming the code is correct, solve the warnings with a cast.
    This particular build case isn't CI tested.

There is a chance the warning is relevant for some platforms, perhaps
    Windows 32-bit ARM7.

- winidn: drop WANT_IDN_PROTOTYPES

`WANT_IDN_PROTOTYPES` was necessary to avoid using a header that came

  years ago and the winidn definitions are part of standard headers (via
  `windows.h`) since Vista.

Auto-detect Vista inside `lib/idn_win32.c` and enable the manual
  definitions if building for an older Windows.

This allows to delete this manual knob from all build-systems.

Also drop the `_SAL_VERSION` sub-case:

Our manual definitions are now only enabled with old systems. We assume
  that code analysis is not run on such systems, allowing us to delete the
  SAL-friendly flavour of these.

These function pointers will have been set when the initial TLS
  handshake was completed. If they are unchanged, there is no need to set
  them again. If they have been changed, as is the case with HTTP/2, we
  don't want to override that change. That would result in the
  http22_recv/send functions being completely bypassed.

Prior to this change a connection that uses Schannel with HTTP/2 would
  fail on renegotiation with error "Received HTTP/0.9 when not allowed".

- cmake: sync HAVE_SIGNAL detection with autotools

`HAVE_SIGNAL` means the availability of the `signal()` function in
  autotools, while in CMake it meant the availability of that function
  _and_ the symbol `SIGALRM`.

The latter is not available on Windows, but the function is, which means
  on Windows, autotools did define `HAVE_SIGNAL`, but CMake did not,
  introducing a slight difference into the binaries.

This patch syncs CMake behaviour with autotools to look for the function
  only.

The logic came with the initial commit adding CMake support to curl, so
  the commit history doesn't reveal the reason behind it. In any case,
  it's best to check the existence of `SIGALRM` directly in the source
  before use. For now, curl builds fine with `HAVE_SIGNAL` enabled and
  `SIGALRM` missing.

The custom check was also non-portable, so this patch deletes it in

- lib: set more flags in config-win32.h

The goal is to add any flag that affect the created binary, to get in
  sync with the ones built with CMake and autotools.

I took these flags from curl-for-win [0], where they've been tested with
  mingw-w64 and proven to work well.

This patch brings them to curl as follows:

- Enable unconditionally those force-enabled via
    `CMake/WindowsCache.cmake`:

- `HAVE_SETJMP_H`
    - `HAVE_STRING_H`
    - `HAVE_SIGNAL` (CMake equivalent is `HAVE_SIGNAL_FUNC`)

- Expand existing guards with mingw-w64:

- `HAVE_STDBOOL_H`
    - `HAVE_BOOL_T`

- Enable Win32 API functions for Windows Vista and later:

- `HAVE_INET_NTOP`
    - `HAVE_INET_PTON`

- Set sizes, if not already set:

- `SIZEOF_OFF_T = 8`
    - `_FILE_OFFSET_BITS = 64` when `USE_WIN32_LARGE_FILES` is set,
      and using mingw-w64.

- Add the remaining for mingw-w64 only. Feel free to expand as desired:

- `HAVE_LIBGEN_H`
    - `HAVE_FTRUNCATE`
    - `HAVE_BASENAME`
    - `HAVE_STRTOK_R`

Future TODO:

- `HAVE_SIGNAL` has a different meaning in CMake. It's enabled when both
    the `signal()` function and the `SIGALRM` macro are found. In
    autotools and this header, it means the function only. For the
    function alone, CMake uses `HAVE_SIGNAL_FUNC`.

- http: try parsing Retry-After: as a number first

Since the date parser allows YYYYMMDD as a date format (due to it being

  a wrong value.

No date format accepted for this header starts with a decimal number, so
  by reversing the check and trying a number first we can deduct that if
  that works, it was not a date.

- Makefile.m32: drop CROSSPREFIX and our CC/AR defaults [ci skip]

This patch aimed to fix a regression [0], where `CC` initialization
  moved beyond its first use. But, on closer inspection it turned out that
  the `CC` initialization does not work as expected due to GNU Make
  filling it with `cc` by default. So unless implicit values were
  explicitly disabled via a GNU Make option, the default value of
  `$CROSSPREFIX` + `gcc` was never used. At the same time the implicit
  value `cc` maps to `gcc` in (most/all?) MinGW envs.

`AR` has the same issue, with a default value of `ar`.

We could reintroduce a separate variable to fix this without ill
  effects, but for simplicity and flexibility, it seems better to drop
  support for `CROSSPREFIX`, along with our own `CC`/`AR` init logic, and
  require the caller to initialize `CC`, `AR` and `RC` to the full
  (prefixed if necessary) names of these tools, as desired.

We keep `RC ?= windres` because `RC` is empty by default.

Also fix grammar in a comment.

- schannel: when importing PFX, disable key persistence

By default, the PFXImportCertStore API persists the key in the user's
  key store (as though the certificate was being imported for permanent,
  ongoing use.)

The documentation specifies that keys that are not to be persisted
  should be imported with the flag PKCS12_NO_PERSIST_KEY.
  NOTE: this flag is only supported on versions of Windows newer than XP
  and Server 2003.

This is take 2 of the original fix. It extends the lifetime of the
  client certificate store to that of the credential handle. The original
  fix which landed in 70d010d and was later reverted in aec8d30 failed to
  work properly because it did not do that.

Minor changes were made to the schannel credential context to support
  closing the client certificate store handle at the end of an SSL session.

With these features detected correctly, CMake Windows builds get closer
  to the autotools and `config-win32.h` ones.

This also fixes detecting `HAVE_FTRUNCATE` correctly, which required
  `unistd.h`.

Fixing `ftruncate()` in turn causes a build warning/error with legacy
  MinGW/MSYS1 due to an offset type size mismatch. This env misses to
  detect `HAVE_FILE_OFFSET_BITS`, which may be a reason. This patch
  force-disables `HAVE_FTRUNCATE` for this platform.

- curl-wolfssl.m4: error out if wolfSSL is not usable

When I explicitly declare, that I would like to have curl built with

  expect, that either I endup with curl having that support, for example
  in form of https support or it wouldn't be available at all.

Downstream projects like for example OpenWrt build curl wolfSSL variant
  with `--with-wolfssl` already, but in certain corner cases it does fail:

configure:25299: checking for wolfSSL_Init in -lwolfssl
    configure:25321: x86_64-openwrt-linux-musl-gcc -o conftest [snip]

- websockets: remodeled API to support 63 bit frame sizes

curl_ws_recv() now receives data to fill up the provided buffer, but can
  return a partial fragment. The function now also get a pointer to a
  curl_ws_frame struct with metadata that also mentions the offset and
  total size of the fragment (of which you might be receiving a smaller
  piece). This way, large incoming fragments will be "streamed" to the
  application. When the curl_ws_frame struct field 'bytesleft' is 0, the
  final fragment piece has been delivered.

curl_ws_recv() was also adjusted to work with a buffer size smaller than
  the fragment size. (Possibly needless to say as the fragment size can
  now be 63 bit large).

curl_ws_send() now supports sending a piece of a fragment, in a
  streaming manner, in addition to sending the entire fragment in a single
  call if it is small enough. To send a huge fragment, curl_ws_send() can
  be used to send it in many small calls by first telling libcurl about
  the total expected fragment size, and then send the payload in N number
  of separate invokes and libcurl will stream those over the wire.

The struct curl_ws_meta() returns is now called 'curl_ws_frame' and it
  has been extended with two new fields: *offset* and *bytesleft*. To help
  describe the passed on data chunk when a fragment is delivered in many
  smaller pieces.

The documentation has been updated accordingly.

- tidy-up: delete parallel/unused feature flags

Detecting headers and lib separately makes sense when headers come in
  variations or with extra ones, but this wasn't the case here. These were
  duplicate/parallel macros that we had to keep in sync with each other
  for a working build. This patch leaves a single macro for each of these
  dependencies:

- Rely on `HAVE_LIBZ`, delete parallel `HAVE_ZLIB_H`.

Also delete CMake logic making sure these two were in sync, along with
    a toggle to turn off that logic, called `CURL_SPECIAL_LIBZ`.

Also delete stray `HAVE_ZLIB` defines.

There is also a `USE_ZLIB` variant in `lib/config-dos.h`. This patch
    retains it for compatibility and deprecates it.

- Rely on `USE_LIBSSH2`, delete parallel `HAVE_LIBSSH2_H`.

Also delete `LIBSSH2_WIN32`, `LIBSSH2_LIBRARY` from
    `winbuild/MakefileBuild.vc`, these have a role when building libssh2
    itself. And `CURL_USE_LIBSSH`, which had no use at all.

Also delete stray `HAVE_LIBSSH2` defines.

- Makefile.m32: deduplicate build rules [ci skip]

After this patch, we reduce the three copies of most `Makefile.m32`
  logic to one. This now resides in `lib/Makefile.m32`. It makes future
  updates easier, the code shorter, with a small amount of added
  complexity.

`Makefile.m32` reduction:

|                   |  bytes | LOC total |  blank |  comment |  code |
  |-------------------|-------:|----------:|-------:|---------:|------:|
  | 7.85.0            |  34772 |      1337 |     79 |      192 |  1066 |
  | before this patch |  17601 |       625 |     62 |      106 |   457 |
  | after this patch  |  11680 |       392 |     52 |      104 |   236 |

Details:

- Change rules to create objects for the `v*` subdirs in the `lib` dir.
    This allows to use a shared compile rule and assumes that filenames
    are not (and will not be) colliding across these directories.
    `Makefile.m32` now also stores a list of these subdirs. They are
    changing rarely though.

- Sync as much as possible between the three `Makefile.m32` scripts'
    rules and their source/target sections.

- After this patch `CPPFLAGS` are all applied to the `src` sources once
    again. This matches the behaviour of cmake/autotools. Only zlib ones
    are actually required there.

- Use `.rc` names from `Makefile.inc` instead of keeping a duplicate.

- Change examples to link `libcurl.dll` by default. This makes building
    trivial, even as a cross-build:
      `CC=x86_64-w64-mingw32-gcc make -f Makefile.m32`
    To run them, you need to move/copy or add-to-path `libcurl.dll`.
    You can select static mode via `CFG=-static`.

- List more of the `Makefile.m32` config variables.

- Drop `.rc` support from examples. It made it fragile without much
    benefit.

- Include a necessary system lib for the `externalsocket.c` example.

- Exclude unnecessary systems libs when building in `-dyn` mode.

- Makefile.m32: major rework [ci skip]

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
    16a58e9f93c7e89e1f87720199388bcfcfa148a4. 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.

- 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 -ll
  dapx
  ```

OpenLDAP LDAP SDK, previously enabled via `USE_LDAP_OPENLDAP=1`:
  ```
  export CURL_CFLAG_EXTRAS = -I<path-to-sdk>/include -DCURL_HAS_OPENLDAP_LDAPSD
  K
  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.

- autotools: allow --enable-symbol-hiding with windows

This local autotools logic was put in place in
  9e24b9c7afbcb81120af4cf3f6cdee49a06d8224 (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.

- autotools: reduce brute-force when detecting recv/send arg list

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
  01fa02d0b545e1433dced2430561f8c0c72b74a9 (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.

- docs: tell about disabled protocols in CURLOPT_*PROTOCOLS_STR.

Disabled protocols are now handled as if they were unknown.
  Also update the possible protocol list.

- cli tool: do not use disabled protocols

As they are now rejected by the library, take care of not passing
  disabled protocol names to CURLOPT_PROTOCOLS_STR and
  CURLOPT_REDIR_PROTOCOLS_STR.

Rather than using the CURLPROTO_* constants, dynamically assign protocol
  numbers based on the order they are listed by curl_version_info().

New type proto_set_t implements prototype bit masks: it should therefore
  be large enough to accomodate all library-enabled protocols. If not,
  protocol numbers beyond the bit count of proto_set_t are recognized but
  "inaccessible": when used, a warning is displayed and the value is
  ignored. Should proto_set_t overflows, enabled protocols are reordered to
  force those having a public CURLPROTO_* representation to be accessible.

Code has been added to subordinate RTMP?* protocols to the presence of
  RTMP in the enabled protocol list, being returned by curl_version_info()
  or not.

- setopt: use the handler table for protocol name to number conversions

This also returns error CURLE_UNSUPPORTED_PROTOCOL rather than
  CURLE_BAD_FUNCTION_ARGUMENT when a listed protocol name is not found.

  this extended use.

Note that disabled protocols are not recognized anymore.

  problems yet.

In addition, gcc 11.3 issues a warning on access to fields of partially
  allocated structures that can occur when the specific storage size is 0:

content_encoding.c: In function ‘Curl_build_unencoding_stack’:
    content_encoding.c:980:21: warning: array subscript ‘struct contenc_write
  r[0]’ is partly outside array bounds of ‘unsigned char[16]’ [-Warray-bo

    In file included from content_encoding.c:49:

    content_encoding.c:977:60: note: in expansion of macro ‘calloc’
      977 |   struct contenc_writer *writer = (struct contenc_writer *)calloc(1
  , sz);

To solve both these problems, the current commit replaces the
  contenc_writer/params structure pairs by "subclasses" of struct
  contenc_writer. These are structures that contain a contenc_writer at
  offset 0. Proper field alignment is therefore handled by the compiler and
  full structure allocation is performed, silencing the warnings.

Next Protocol Negotiation is a TLS extension that was created and used
  for agreeing to use the SPDY protocol (the precursor to HTTP/2) for
  HTTPS. In the early days of HTTP/2, before the spec was finalized and
  shipped, the protocol could be enabled using this extension with some
  servers.

curl supports the NPN extension with some TLS backends since then, with
  a command line option `--npn` and in libcurl with
  `CURLOPT_SSL_ENABLE_NPN`.

HTTP/2 proper is made to use the ALPN (Application-Layer Protocol
  Negotiation) extension and the NPN extension has no purposes
  anymore. The HTTP/2 spec was published in May 2015.

Today, use of NPN in the wild should be extremely rare and most likely
  totally extinct. Chrome removed NPN support in Chrome 51, shipped in
  June 2016. Removed in Firefox 53, April 2017.

- configure: fail if '--without-ssl' + explicit parameter for an ssl lib

A side effect of a previous change to configure (576e507c78bdd2ec88)
  exposed a non-critical issue that can happen if configure is called with
  both '--without-ssl' and some parameter setting the use of a ssl library
  (e.g. --with-gnutls). The configure script would end up assuming this is
  a MultiSSL build, due to the way the case statement is written.

I have changed the order of the variables in the string concatenation
  for the case statement and also tweaked the options so that
  --without-ssl never turns the build into a MultiSSL one and also clearly
  stating that there are conflicting parameters if the user sets it like

- CURLOPT_WILDCARDMATCH.3: Fix backslash escaping under single quotes

Lintian (on Debian) has been complaining about this for a while but
   I didn't bother initially as the groff parser that we use is not
   affected by this.

But I have now noticed that the online manpage is affected by it:
   https://curl.se/libcurl/c/CURLOPT_WILDCARDMATCH.html

(I'm using double quotes for quoting-only down below)

The section that should be parsed as "'\'" ends up being parsed as
   "'´".

This is due to roffit not parsing "'\\'" correctly, which is fine
   as the "correct" way of writing "'\'" is "'\e'" instead.

Note that this fix is not enough to fix the online manpage at
   curl's website, as roffit seems to parse it wrongly either way.

My intent is to at least fix the manpage so that roffit can
   be changed to parse "'\e'" correctly (although I suggest making
   roffit parse both ways correctly, since that's what groff does).

When doing a huge amount of parallel transfers, we must not add them to

- cmake: fix original MinGW builds

1. Re-enable `HAVE_GETADDRINFO` detection on Windows

Commit d08ee3c83d6bd416aef62ff844c98e47c4682429 (in 2013) added logic
     that automatically assumed `getaddrinfo()` to be present for builds
     with IPv6 enabled. As it turns out, certain toolchains (e.g. original
     MinGW) by default target older Windows versions, and thus do not
     support `getaddrinfo()` out of the box. The issue was masked for
     a while by CMake builds forcing a newer Windows version, but that
     logic got deleted in commit 8ba22ffb2030ed91312fc8634e29516cdf0a9761.
     Since then, some CI builds started failing due to IPv6 enabled,
     `HAVE_GETADDRINFO` set, but `getaddrinfo()` in fact missing.

It also turns out that IPv6 works without `getaddrinfo()` since commit
     67a08dca27a6a07b36c7f97252e284ca957ff1a5 (from 2019, via #4662). So,
     to resolve all this, we can now revert the initial commit, thus
     restoring `getaddrinfo()` detection and support IPv6 regardless of its
     outcome.

2. Omit `bcrypt` with original MinGW

Original (aka legacy/old) MinGW versions do not support `bcrypt`

     unsupported API and do not link `bcrypt`, respectively, when using
     original MinGW.

This patch ports that logic to CMake, fixing the link error:
     `c:/mingw/bin/../lib/gcc/mingw32/9.2.0/../../../../mingw32/bin/ld.exe: can
  not find -lbcrypt`

Viktor Szakats (15 Aug 2022)

- Makefile.m32: allow -nghttp3/-ngtcp2 without -ssl [ci skip]

Before this patch `-nghttp3`/`-ngtcp2` had an effect only when `-ssl`
  was also enabled. `-ssl` meaning OpenSSL (and its forks). After
  8a13be227eede2601c2b3b1c63e08b3dc9b35dd5 nghttp3/ngtcp2 can also be
  used together with wolfSSL. This patch adds the ability to enable
  `-nghttp3`/`-ngtcp2` independently from `-ssl` (OpenSSL), allowing to
  use it with wolfSSL or other, future TLS backends.

Before this patch, it was fine to enable `-nghttp3`/`-ngtcp2`
  unconditionally. After this patch, this is no longer the case, and now
  it's the user's responsibility to enable `-nghttp3`/`-ngtcp2` only
  together with a compatible TLS backend.

When using a TLS backend other than OpenSSL, the TLS-specific ngtcp2
  library must be configured manually, e.g.:
    `export CURL_LDFLAG_EXTRAS=-lngtcp2_crypto_wolfssl`

(or via `NGTCP2_LIBS`)

- cmdline-opts/gen.pl: improve performance

On some systems, the gen.pl script takes nearly two minutes for the
  generation of the main-page, which is a completely unacceptable time.

The slow performance has two causes:
  1. Use of a regex locale operator
  2. Useless invokations of loops

The commit addresses the first issue by replacing the "\W" wiht
  [^a-zA-Z0-9_], which is, according to regex101.com, functionally
  equivalent to the previous operation, except that it is obviously
  limited to ASCII only, which is fine, as the curl project is
  English-only anyway.

The second issue is being addressed by only running the loop if the line
  contains a "--" in it. The loop may be completeley removed in the
  future.

- curl-functions.m4: check whether atomics can link rather than just compile

Some build toolchains support C11 atomics (i.e., _Atomic types), but
  will not link the associated atomics runtime unless a flag is passed. In
  such an environment, linking an application with libcurl.a can fail due
  to undefined symbols for atomic load/store functions.

I encountered this behavior when upgrading curl to 7.84.0 and attempting
  to build with Solaris Studio 12.6. Solaris provides the flag
  -xatomic=[gcc | studio], allowing users to link to one of two atomics
  runtime implementations. However, if the user does not provide this
  flag, then neither runtime is linked. This led to builds failing in CI.

- Makefile.m32: stop trying to build libcares.a [ci skip]

Before this patch, `lib/Makefile.m32` had a rule to build `libcares.a` in
  `-cares`-enabled builds, via c-ares's own `Makefile.m32`. Committed in
  2007 [1]. The commit message doesn't specifically address this particular
  change. This logic comes from the times when c-ares was part of the curl
  source tree, hence the special treatment.

This feature creates problems when building c-ares first, using CMake
  and pointing `LIBCARES_PATH` to its install prefix, where `Makefile.m32`
  is missing in such case. A sub-build for c-ares is undesired also when
  c-ares had already been build via its own `Makefile.m32`.

To avoid the sub-build, this patch deletes its Makefile rule. After this
  patch `libcares.a` needs to be manually built before using it in
  `Makefile.m32`. Aligning it with the rest of dependencies.

- build: improve OS string in CMake and `config-win32.h`

This patch makes CMake fill the "OS string" with the value of
  `CMAKE_C_COMPILER_TARGET`, if passed. This typically contains a triplet,
  the same we can pass to `./configure` via `--host=`.

For non-CMake, non-autotools, Windows builds, this patch adds the ability
  to override the default `OS` value in `lib/config-win32.h`.

With these its possible to get the same OS string across the three build
  systems.

This patch supersedes the earlier, partial, CMake-only solution:
  435f395f3f8c11eebfcc243ca55ebcc11a19b8b8, thus retiring the
  `CURL_OS_SUFFIX` CMake option.

  `CURL_CC=clang` set on current latest debian:unstable or earlier, where

- openssl: add `CURL_BORINGSSL_VERSION` to identify BoringSSL

BoringSSL doesn't keep a version number, and doesn't self-identify itself
  via any other revision number via its own headers. We can identify
  BoringSSL revisions by their commit hash. This hash is typically known by
  the builder. This patch adds a way to pass this hash to libcurl, so that
  it can display in the curl version string:

For example:

`CFLAGS=-DCURL_BORINGSSL_VERSION="c239ffd0"`

```
  curl 7.84.0 (x86_64-w64-mingw32) libcurl/7.84.0 BoringSSL/c239ffd0 (Schannel)
   zlib/1.2.12 [...]
  Release-Date: 2022-06-27

   mqtt pop3 [...]
  Features: alt-svc AsynchDNS brotli gsasl HSTS HTTP2 HTTP3 HTTPS-proxy IDN IPv
  6 Kerberos [...]
  ```

The setting is optional, and if not passed, BoringSSL will appear without
  a version number, like before this patch.

- cmake: do not force Windows target versions

The goal of this patch is to avoid CMake forcing specific Windows
  versions and rely on toolchain defaults or manual selection instead.
  This gives back control to the user. This also brings CMake closer to
  how autotools and `Makefile.m32` behaves in this regard.

- CMake had a setting `ENABLE_INET_PTON` defaulting to `ON`, which did
    nothing else than fixing the Windows build target to Vista. This also
    happened when the toolchain did not have Vista support (e.g. original
    MinGW), breaking such builds.

In other environments it did not make a user-facing difference,
    because libcurl has its own pton() implementation, so it works well
    with or without Vista's inet_pton().

This patch drops this setting. inet_pton() is now used whenever
    building for Vista or newer, either when requested manually or by
    default with modern toolchains (e.g. mingw-w64). Older envs will fall
    back to curl's pton().

Ref: https://github.com/curl/curl/pull/9027#issuecomment-1164157604

- When the user did no select a Windows target version manually, stop
    explicitly targeting Windows XP, and instead use the toolchain default.

This may pose an issue with old toolchains defaulting to pre-XP
    targets. In such case you must manually target Windows XP via:
      `-DCURL_TARGET_WINDOWS_VERSION=0x0501`
    or
      `-DCMAKE_C_FLAGS=-D_WIN32_WINNT=0x0501`

- windows: improve random source

- Use the Windows API to seed the fallback random generator.

This ensures to always have a random seed, even when libcurl is built
    with a vtls backend lacking a random generator API, such as rustls
    (experimental), GSKit and certain mbedTLS builds, or, when libcurl is
    built without a TLS backend. We reuse the Windows-specific random
    function from the Schannel backend.

- Implement support for `BCryptGenRandom()` [1] on Windows, as a
    replacement for the deprecated `CryptGenRandom()` [2] function.

It is used as the secure random generator for Schannel, and also to
    provide entropy for libcurl's fallback random generator. The new
    function is supported on Vista and newer via its `bcrypt.dll`. It is
    used automatically when building for supported versions. It also works
    in UWP apps (the old function did not).

- Clear entropy buffer before calling the Windows random generator.

This avoids using arbitrary application memory as entropy (with
    `CryptGenRandom()`) and makes sure to return in a predictable state
    when an API call fails.

- ftp: restore protocol state after http proxy CONNECT

connect_init() (lib/http_proxy.c) swaps out the protocol state while
  working on the proxy connection, this is then restored by
  Curl_connect_done() after the connection completes.

ftp_do_more() extracted the protocol state pointer to a local variable
  at the start of the function then calls Curl_proxy_connect(). If the proxy
  connection completes, Curl_proxy_connect() will call Curl_connect_done()
  (via Curl_proxyCONNECT()), which restores data->req.p to point to the ftp
  protocol state instead of the http proxy protocol state, but the local
  variable in ftp_do_more still pointed to the old value.

Ultimately this meant that the state worked on by ftp_do_more() was the
  http proxy state not the ftp state initialised by ftp_connect(), but
  subsequent calls to any ftp_ function would use the original state.

For my use-case, the visible consequence was that ftp->downloadsize was
  never set and so downloaded data was never returned to the application.

This commit updates the ftp protocol state pointer in ftp_do_more() after
  Curl_proxy_connect() returns, ensuring that the correct state pointer is
  used.

- curl_setup: include _mingw.h

Prior to this change _mingw.h needed to be included in each unit before
  evaluating __MINGW{32,64}_xxx_VERSION macros since it defines them. It
  is included only in some mingw headers (eg stdio.h) and not others
  (eg windows.h) so it's better to explicitly include it once.

- rand: stop detecting /dev/urandom in cross-builds

- Prevent CMake to auto-detect /dev/urandom when cross-building.
    Before this patch, it would detect it in a cross-build scenario on *nix
    hosts with this device present. This was a problem for example with
    Windows builds, but it could affect any target system with this device
    missing. This also syncs detection behaviour with autotools, which also
    skips it for cross-builds.
  - Also, make sure to never use the file RANDOM_FILE as entropy for libcurl's
    fallback random number generator on Windows. Windows does not have the
    concept of reading a random stream from a filename, nor any guaranteed
    non-world-writable path on disk. With this, a manual misconfiguration or
    an overeager auto-detection can no longer result in a user-controllable
    seed source.

- Makefile.m32: stop forcing XP target with ipv6 enabled [ci skip]

Since this [1] commit in 2011, `_WIN32_WINNT` was set fixed to Windows
  XP when the `-ipv6` option is selected. Maybe this was added to support
  pre-XP Windows versions (?). These days libcurl builds fine for both XP
  and post-XP versions with IPv6 support enabled. The relevance of pre-XP
  version is also low by now. Other build methods also do not impose such
  limitation for a similar configuration. So, drop this hard-wired
  `_WIN32_WINNT` limit from `Makefile.m32`, thus building for the default
  Windows version set by the compiler. This is Vista for recent MinGW
  versions.

Old behaviour can be restored by setting this envvar:
  export CURL_CFLAG_EXTRAS=-D_WIN32_WINNT=0x0501

- curl_easy_pause.3: remove explanation of progress function

The progress function behavior is more nuanced and the user is better

  it in the curl_easy_pause doc.

The progress function can only be called at least once per second if an
  appropriate multi transfer function is called (eg curl_multi_perform) in
  that time. For a paused transfer there may not be such a call. Rather
  than explain this in detail in the curl_easy_pause doc, rely on the user
  reading the CURLOPT_PROGRESSFUNCTION doc.

- version: rename threadsafe-init to threadsafe

Referring to Daniel's article [1], making the init function thread-safe
  was the last bit to make libcurl thread-safe as a whole. So the name of
  the feature may as well be the more concise 'threadsafe', also telling
  the story that libcurl is now fully thread-safe, not just its init
  function. Chances are high that libcurl wants to remain so in the
  future, so there is little likelihood of ever needing any other distinct
  `threadsafe-<name>` feature flags.

For consistency we also shorten `CURL_VERSION_THREADSAFE_INIT` to
  `CURL_VERSION_THREADSAFE`, update its description and reference libcurl's
  thread safety documentation.

  supports \n, \r and \t for newline, carriage return and tabs
  respectively.

If the password does not start with a double quote, it will end at first
  white space and no escaping is performed.

WARNING: this change is not entirely backwards compatible. If anyone
  previously used a double-quote as the first letter of their password,
  the parser will now get it differently compared to before. This is
  highly unfortunate but hard to avoid.

- cmake: support adding a suffix to the OS value

CMake automatically uses the `CMAKE_SYSTEM_NAME` value to fill the OS
  string appearing in the --version output after the curl version number,
  for example:

'curl 7.83.1 (Windows)'

This patchs adds the ability to pass a suffix that is appended to this
  value. It's useful to add CPU info or other platform details,
  for example:

'curl 7.83.1 (Windows-x64)'

Closes #8919

Without this patch, libidn2 detection doesn't even seem to be

In CMakeLists.txt there is an attempt to detect `stricmp()`, and in

  a result, but this macro wasn't used anywhere in the source. This
  patch makes use of it as an alternative when alpha-sorting the
