Only actually needed servers should be listed and none is then implied
if no servers are listed.
Outputs a warning if "none" is still set as a server.

Write out 9-length frames to client's WRITEFUNCTION

Applied the same workaround to the build examples as used earlier in CI.
That is, drop `<path> from `--with-ngtcp2=<path>` and configure env
`PKG_CONFIG_PATH` instead.
Till the root cause is fixed.

Changed strategy to start up and terminate resolver thread.
When starting up:
Start the thread with mutex acquired, wait for signal from thread that
it started and has incremented the ref counter. Thread set
pthread_cancel() to disabled before that and only enables cancelling
during resolving itself. This assure that the ref counter is correct and
the unlinking of the resolve context always happens.
When shutting down resolving:
If ref counting shows thread has finished, join it, free everything. If
thread has not finished, try pthread_cancel() (non Windows), but keep
the thread handle around.
When destroying resolving:
Shutdown first, then, if the thread is still there and 'quick_exit' is
not set, join it and free everything. This might occur a delay if
getaddrinfo() hangs and cannot be interrupted by pthread_cancel().
Destroying resolving happens when another resolve is started on an
easy handle or when the easy handle is closed.
Add test795 to check that connect timeout triggers correctly
when resolving is delayed. Add debug env var `CURL_DNS_DELAY_MS`
to simulate delays in resolving.
Fix test1557 to set `quick_exit` and use `xxx.invalid` as domain
instead of `nothing` that was leading to hangers in CI.
Closes#18263
When an application install its own OpenSSL verify callback and that
callback invokes `SSL_set_retry_verify()`, the transfer is automatically
paused and does not progress the connect attempt any further until
unpaused via `curl_easy_pause().
Added test758 to verify.

- they are fake anyway
- these ones look more obvious fake and in need of replacement
- avoids the risk that they might decode to something of value

Add support for CURLOPT_READFUNCTION with WebSocket urls when *not* in
connect-only mode, e.g. when using curl_multi_perform.
Install the callback function and set CURLOPT_UPLOAD. Return
CURL_READFUNC_PAUSE when having nothing more to send and unpause the
transfer when more data is ready.
This will send the read bytes in a WebSocket BINARY frame.
Add support for this mode in the pytest "ws_data" client and have all
tests run in 'curl_ws_send/recv' and 'peform' mode as well.
Add `curl_ws_start_frame()`. Document, cover in libcurl-ws.md and
explain the READFUNCTION mode for websockets.
Add example `websocket-updown` for this.
Closes#17683
In CI we want to ensure that examples build cleanly, but we don't want
to actually run them there. Meaning it's enough to just compile, but not
link them in CI. Saving time up to 2-4x (MSVC), and disk space up
to 1.2GB (or 8-70x).
Add a new cmake target that compiles all examples without linking them
into runnable binaries. Keep a full build for a single example to test
if it links correctly.
Also:
- CI: switch over all `curl-examples` targets to `curl-examples-build`
- GHA/linux-old: build examples in one of the cmake builds.

Hold them for half the normal lifetime. Helps when told to transfer N
URLs in quick succession that all use the same non-resolving hostname.
Done by storing a DNS entry with a NULL pointer for 'addr'.

ultimately never merged.

Adds `curl_off_t curl_multi_get_offt(CURLM *multi_handle, CURLMinfo_offt
info)` to the multi interface with enums:
* CURLMINFO_XFERS_CURRENT: current number of transfers
* CURLMINFO_XFERS_RUNNING: number of running transfers
* CURLMINFO_XFERS_PENDING: number of pending transfers
* CURLMINFO_XFERS_DONE: number of finished transfers to read
* CURLMINFO_XFERS_ADDED: total number of transfers added, ever
Add documentation for functions and info enums.
Add use in the curl command line tool to replace two static
variables counting the same "from the outside".

To reduce log noise in local test runs:
- move the `buildinfo.txt` dump and header info lines
`OS:`, `Perl:`, `diff:` behind a `--ci` `runtests.pl` option.
- enable this option for the CI test targets.
- hide `Env:` header info line if empty.
- merge `Env:` output into a single `logmsg()` call.
Closes#18147
Some CURLOPT constants defined in the curl public headers were initially
enums (= ints), or macros with bare numeric values. Recent curl releases
upgraded them to `long` constants, to make them pass correctly to
`curl_easy_setop()` by default, i.e. without requiring a `(long)` cast.
This patch drops such casts from the examples embedded in the docs. At
the same time it documents which curl release made them `long` types,
to keep them useful when working with previous libcurl versions.
Also:
- drop a `(long)` cast that was never necessary.
- CURLOPT_ALTSVC_CTRL.md: bump local copy of macros to long.
- test1119: make it ignore symbols ending with an underscore, to skip
wildcard, e.g. `**CURLAUTH_***`.
