CMake Error at bld-curl/_pkg/lib/cmake/CURL/CURLConfig.cmake:62 (add_library):
add_library cannot create ALIAS target "CURL::libcurl" because target
"CURL::libcurl_shared" is imported but not globally visible.
Call Stack (most recent call first):
CMakeLists.txt:39 (find_package)
```
tests/cmake reproducer (requires #16973):
```shell
export CMAKE_CONSUMER=/path/to/CMake-3.12.0/bin/cmake
./test.sh find_package
```
I don't understand what this error says, why it happens in certain CMake
versions, and why a workaround is necessary for what seems like
a standard export/consume configuration. This patch is based on internet
suggestions and other projects ending up with this workaround.

With a meta_hash at each connection (similar to easy handle, let
multi_ev.c store its pollsets as meta data, no longer needing its own
hashes.
This eliminates the last use of Curl_hash_offt. Remove it.
Closes#17095
A "TE" request header is allowed in HTTP/2 when it only carries the
"trailers" value. RFC 9113 ch. 8.2.2. Check client supplied TE values
for the "trailers" token and only pass that one in a HTTP/2 request.
Add test_01_17 to verify.

Fix a bug in timeout handling for connection shutdowns that led to
default timeout of 2 seconds not being in effect.
Only set the shutdown timeout expiry when operating on a non-admin
transfers. Admin handles are only temproarily tied to a connection.

Build/install the man page. Install the script.
This an "import" rather than just adding the script into the release tarball
with maketgz to make sure the tarball build is completely reproducible.

Closes#17035
- fix filter expression for cache step.
It did not cause an issue because `wolfssh` is always paired with
a `wolfssl*`.
- build `wolfssh` against `wolfssl-opensslextra` (was: `wolfssl-all`).
It makes `wolfssh` builds `OPENSSL_COEXIST`-compatible, and clarifies
its use in the clang-tidy job. The earlier mixup didn't cause issues
because the clang-tidy job is compile-only (using their headers only.)
Useful side-effect is making the wolfssh build valgrind-tested.

Add `--retry=<num>` option to tell runtests to retry the first `<num>`
tests that failed. Retries aren't run right away, but added to the end
of the test queue. Once all retry slots are used, test fail as normal.
In CI, typically a single test fails for flakiness, and rarely over 5.
Make the `ci-test` targets default to `--retry=5`.

This adds another bitflag on CURLOPT_WS_OPTIONS (CURLWS_NOAUTOPONG) that
disables the default and automatic PONG reply in the WebSocket layer.

Closes#16744
Do not set a transport parameter idle timeout, meaning we have no such
thing from our side. The remote setting then applies.
In ngtcp2, set its "keep-alive" timer to prevent a possible remote idle
timeout to tear down the connection while we have active transfers on
that connection.
Closes#17057
To keep testing these with MSVC:
- UWP !ssl
- arm64 build on the `windows-11-arm` runner
- examples
- OpenSSH-Windows (fix install on `windows-11-arm`)
- `windows-2025` runner
- cmake pre-fill checker
Surprise: UWP doesn't support SSPI, which is required by curl's Schannel
backend. Thus, no TLS support for this UWP build. It also suggests
the Schannel UWP mingw-w64 binaries may be broken and just a happy build
accident thanks to mingw-w64 headers being inaccurate.
Building zlib + libssh2 might actually take up to 2+ minutes with vcpkg,
instead of the previously estimated <1.5 minutes.

Depending on timing when the server aborting the connection is detected,
the reported curl exit code may vary. Check for the possible set of
expected codes instead of a single one.
Closes#17083
Change multi's book keeping of transfers to no longer use lists, but a
special table and bitsets for unsigned int values.
`multi-xfers` is the `uint_tbl` where `multi_add_handle()` inserts a new
transfer which assigns it a unique identifier `mid`. Use bitsets to keep
track of transfers that are in state "process" or "pending" or
"msgsent".
Use sparse bitsets to replace `conn->easyq` and event handlings tracking
of transfers per socket. Instead of pointers, keep the mids involved.
Provide base data structures and document them in docs/internal:
* `uint_tbl`: a table of transfers with `mid` as lookup key,
handing out a mid for adds between 0 - capacity.
* `uint_bset`: a bitset keeping unsigned ints from 0 - capacity.
* `uint_spbset`: a sparse bitset for keeping a small number of
unsigned int values
* `uint_hash`: for associating `mid`s with a pointer.
This makes the `mid` the recommended way to refer to transfers inside
the same multi without risk of running into a UAF.
Modifying table and bitsets is safe while iterating over them. Overall
memory requirements are lower as with the double linked list apprach.
Closes#16761
Currently the DNS server only responds to A and AAAA queries. It always
responds with a fixed response: the localhost address. Three times.
It should work fine over either IPv4 or IPv6, but I don't think it
matters much for curl testing.
The idea is to allow curl tests to use "normal" DNS hostnames (using the
normal name resolving code paths) and still use the local test servers.
This setup currently only works if curl is built with c-ares because
redirecting DNS requests to our test server when using getaddrinfo() is
not easy.
This should be extended to respond to HTTPS queries as well to allow
more testing there, as c-ares is always used for that.
Test 2102 is the first test using this.
Closes#17015
With the new addition of OpenSSL QUIC API support and the support in
ngtcp2 main branch, make the necessary adjustments in curl to support
this combination.
- add support in configure.ac to detect the feature OPENSSL_QUIC_API2 in
openssl
- initialise ngtcp2 properly in this combination
- add a Curl_vquic_init() for global initialisation that ngtcp2 likes
for performance reasons
- add documentation on how to build in docs/HTTP3.md
- add CI testing in http3-linux.yml

Closes#17027
Adds a "meta_hash" to each easy handle for keeping special data during
operations. All meta data set needs to add its destructor callback, so
that meta data gets destroyed properly when the easy handle is cleaned
up or reset.
Add data->master_mid for "sub" transfers that belong to a "master" easy
handle. When a "sub" transfer is done, the corresponding "master" can
add a callback to be invoked. Used in DoH name resolution.
DoH: use easy meta hash to add internal structs for DoH name resolution.
One in each in each probe easy handle. When probes are done, response
data is copied from the probe to the initiating easy.
This allows DoH using transfers and their probes to be cleaned up in any
sequence correctly.
Fold DoH cleanup into the Curl_async_shutdown() and Curl_async_destroy()
functions.
Closes#16384
Enable it for `_MSC_VER <= 1943`.
Omit it for not yet CI-tested MSVC versions, to avoid hitting unfixed
warnings emitted by future toolchain releases. It means we need
to explicitly opt-in to newer MSVC versions while fixing any new issues.
The newly enabled warnings did not reveal new issues. It hints that we
catch those with clang/gcc. Yet, these warnings may be useful for local
development done with MSVC.
Also:
- disable and document warnings that don't seem useful, unactionable,
or unfixable.
- disable and document warnings found in Windows SDK headers.
- tidy up a few comments, also to avoid
`-Wdocumentation-unknown-command`, part of llvm/clang `-Wall`.
```
lib\dynhds.h(159,29): error : unknown command tag name [-Werror,-Wdocumentation-unknown-command]
lib\ftp.c(337,15): error : unknown command tag name [-Werror,-Wdocumentation-unknown-command]
```
(This patch did not end up enabling `-Wall` for clang-cl.)
Closes#17050
In the last 1-2 days, curl's vcpkg binary cache entries stored by GHA
apparently disappeared, and each vcpkg job is now rebuilding everything
on every run. This takes up to 40 minutes per job. New cache entries
fail on upload with messages like:
```
Completed submission of nghttp2:arm64-android@1.65.0 to 0 binary cache(s) in 172 ms
```
(note the zero.)
This coincided with my adding support for windows-11-arm and touching
some jobs affected. Yet, unrelated. It also affects Android jobs. The root
cause is a runner image update bumping the vcpkg tool.
The latest vcpkg tool also has this issue.
As a temporary workaround, stop using vcpkg in CI.
