A new error code to be used when an internal field grows too large, like

Windows compilers define `_WIN32` automatically. Windows SDK headers
or build env defines `WIN32`, or we have to take care of it. The
agreement seems to be that `_WIN32` is the preferred practice here.
Make the source code rely on that to detect we're building for Windows.
Public `curl.h` was using `WIN32`, `__WIN32__` and `CURL_WIN32` for
Windows detection, next to the official `_WIN32`. After this patch it
only uses `_WIN32` for this. Also, make it stop defining `CURL_WIN32`.
There is a slight chance these break compatibility with Windows
compilers that fail to define `_WIN32`. I'm not aware of any obsolete
or modern compiler affected, but in case there is one, one possible
solution is to define this macro manually.
grepping for `WIN32` remains useful to discover Windows-specific code.
Also:
- extend `checksrc` to ensure we're not using `WIN32` anymore.
- apply minor formatting here and there.
- delete unnecessary checks for `!MSDOS` when `_WIN32` is present.

The current design of the Hyper integration requires rebuilding the
Hyper clientconn for each request. However, building the clientconn
requires resending the HTTP/2 connection preface, which is incorrect
from a protocol perspective. That in turn causes servers to send GOAWAY
frames, effectively degrading performance to "no connection reuse" in
the best case. It may also be triggering some bugs where requests get
dropped entirely and reconnects take too long.
This doesn't rule out HTTP/2 support with Hyper, but it may take a
redesign of the Hyper integration in order to make things work.

Earlier this year we changed our own stderr variable to use the standard
name `stderr` (to avoid bugs where someone is using `stderr` instead of
the curl-tool specific variable). This solution needed to override the
standard `stderr` symbol via the preprocessor. This in turn didn't play
well with unity builds and caused curl tool to crash or stay silent due
to an uninitialized stderr. This was a hard to find issue, fixed by
manually breaking out one file from the unity sources.
To avoid two these two tricks, this patch implements a different
solution: Restore using our own local variable for our stderr output and
leave `stderr` as-is. To avoid using `stderr` by mistake, add a
`checksrc` rule (based on logic we already used in lib for `strerror`)
that detects any `stderr` use in `src` and points to using our own
variable instead: `tool_stderr`.

Although MS doesn't document it, Schannel will not negotiate TLS 1.3

limits the user to earlier versions of TLS.

Add support for command line variables. Set variables with --variable
name=content or --variable name@file (where "file" can be stdin if set
to a single dash (-)).
Variable content is expanded in option parameters using "{{name}}"
(without the quotes) if the option name is prefixed with
"--expand-". This gets the contents of the variable "name" inserted, or
a blank if the name does not exist as a variable. Insert "{{" verbatim
in the string by prefixing it with a backslash, like "\\{{".
Import an environment variable with --variable %name. It makes curl exit
with an error if the environment variable is not set. It can also rather
get a default value if the variable does not exist, using =content or
@file like shown above.
Example: get the USER environment variable into the URL:
--variable %USER
--expand-url = "https://example.com/api/{{USER}}/method"
When expanding variables, curl supports a set of functions that can make
the variable contents more convenient to use. It can trim leading and
trailing white space with "trim", output the contents as a JSON quoted
string with "json", URL encode it with "url" and base 64 encode it with
"b64". To apply functions to a variable expansion, add them colon
separated to the right side of the variable. They are then performed in
a left to right order.
Example: get the contents of a file called $HOME/.secret into a variable
called "fix". Make sure that the content is trimmed and percent-encoded
sent as POST data:
--variable %HOME=/home/default
--expand-variable fix@{{HOME}}/.secret
--expand-data "{{fix:trim:url}}"

New cfilter HTTP-CONNECT for h3/h2/http1.1 eyeballing.
- filter is installed when `--http3` in the tool is used (or
the equivalent CURLOPT_ done in the library)
- starts a QUIC/HTTP/3 connect right away. Should that not
succeed after 100ms (subject to change), a parallel attempt
is started for HTTP/2 and HTTP/1.1 via TCP
- both attempts are subject to IPv6/IPv4 eyeballing, same
as happens for other connections
- tie timeout to the ip-version HAPPY_EYEBALLS_TIMEOUT
- use a `soft` timeout at half the value. When the soft timeout
expires, the HTTPS-CONNECT filter checks if the QUIC filter
has received any data from the server. If not, it will start
the HTTP/2 attempt.
HTTP/3(ngtcp2) improvements.
- setting call_data in all cfilter calls similar to http/2 and vtls filters
for use in callback where no stream data is available.
- returning CURLE_PARTIAL_FILE for prematurely terminated transfers
- enabling pytest test_05 for h3
- shifting functionality to "connect" UDP sockets from ngtcp2
implementation into the udp socket cfilter. Because unconnected
UDP sockets are weird. For example they error when adding to a
pollset.
HTTP/3(quiche) improvements.
- fixed upload bug in quiche implementation, now passes 251 and pytest
- error codes on stream RESET
- improved debug logs
- handling of DRAIN during connect
- limiting pending event queue
HTTP/2 cfilter improvements.
- use LOG_CF macros for dynamic logging in debug build
- fix CURLcode on RST streams to be CURLE_PARTIAL_FILE
- enable pytest test_05 for h2
- fix upload pytests and improve parallel transfer performance.
GOAWAY handling for ngtcp2/quiche
- during connect, when the remote server refuses to accept new connections
and closes immediately (so the local conn goes into DRAIN phase), the
connection is torn down and a another attempt is made after a short grace
period.
This is the behaviour observed with nghttpx when we tell it to shut
down gracefully. Tested in pytest test_03_02.
TLS improvements
- ALPN selection for SSL/SSL-PROXY filters in one vtls set of functions, replaces
copy of logic in all tls backends.
- standardized the infof logging of offered ALPNs
- ALPN negotiated: have common function for all backends that sets alpn proprty
and connection related things based on the negotiated protocol (or lack thereof).
- new tests/tests-httpd/scorecard.py for testing h3/h2 protocol implementation.
Invoke:
python3 tests/tests-httpd/scorecard.py --help
for usage.
Improvements on gathering connect statistics and socket access.
- new CF_CTRL_CONN_REPORT_STATS cfilter control for having cfilters
report connection statistics. This is triggered when the connection
has completely connected.
- new void Curl_pgrsTimeWas(..) method to report a timer update with
a timestamp of when it happend. This allows for updating timers
"later", e.g. a connect statistic after full connectivity has been
reached.
- in case of HTTP eyeballing, the previous changes will update
statistics only from the filter chain that "won" the eyeballing.
- new cfilter query CF_QUERY_SOCKET for retrieving the socket used
by a filter chain.
Added methods Curl_conn_cf_get_socket() and Curl_conn_get_socket()
for convenient use of this query.
- Change VTLS backend to query their sub-filters for the socket when
checks during the handshake are made.
HTTP/3 documentation on how https eyeballing works.

If curl --write-out "%%{http_code}" is executed in a batch file:
%{http_code}
If curl --write-out "%{http_code}" is executed from the command prompt:
%{http_code}
If curl --write-out "%%{http_code}" is executed from the command prompt:

At the command prompt something like "%{speed_download}%{http_code}"

- 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

FTP port name resolving. This restriction is now documented and we

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.

- Add support for `ZLIB_LIBS` to override `-lz`.
- Omit object files when building examples.
- Default `CC` to `gcc` once again, for convenience. (Caveat: compiler

- 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

Windows/MinGW32-specific anymore.
- Add support for new `CFG` options: `-map`, `-debug`, `-trackmem`
- Set `-DNDEBUG` by default.

- single: the last provided value replaces the earlier ones
- append: it supports being provided multiple times
- boolean: on/off values
- mutex: flag-like option that disable anoter flag
The 'gen.pl' script then outputs the proper and unified language for
each option's multi-use behavior in the generated man page.
The multi: header is requires in each .d file and will cause build error
if missing or set to an unknown value.
Closes#9759
They were previously (erroneously) added manually to tool_listhelp.c
which would make them get removed again when the file is updated next
time, unless added correctly here in header.d

"You never needed a pass phrase" reads like it's about to be followed by
something like "until version so-and-so", but that is not what is
intended. Change to "You never need a pass phrase". There are two
instances of this text, so make sure to update both.
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.

Example programs targeting a deprecated feature/option are commented with
a warning about it.
Other examples are adapted to not use deprecated options.
Closes#9661
The former way that also suggested using a non-existing file to just
enable the cookie engine could lead to developers maybe a bit carelessly
guessing a file name that will not exist, and then in a future due to
circumstances, such a file could be made to exist and then accidentally
libcurl would read cookies not actually meant to.

Closes#9654
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.
Closes#9642
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
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
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.

The example program chkspeed uses strncasecmp() which is not portable
