- move the state struct from config to global. It is used as a single
instance anyway so might as well be a single one to save memory.
- simplify and combine several conditions
- set default retry delay inititally
- use better struct field names to make it easier to understand their
purposes
- remove the state->outfiles field as it was not necessary
- remove superfluous glob cleanup call
- move conditions around to remove an indent level
- move the ->url NULL check
Takes single_transfer()'s complexity score down from 78 to 68.

Prior to this change curl would show the generic error message
"curl: (58) Problem with the local SSL certificate".

Because if it fails, the contents of the output buffer is undefined.

Deduce that the transfer response expects headers by the protocol
handler implementing `write_resp_hd` callback. This eleminates the
`getheader` parameter in the `Curl_xfer_setup_*()` methods.
Add an implementation to RTSP for `write_resp_hd`, joining the HTTP
protocol in the only handlers having it.
Reverse the default of request's `header` bit that signals that headers
are expected. Default is now FALSE, set to TRUE when setting up the
transfer by presence of `write_resp_hd` in the protocol handler.
Closes#18218
When we cancel async resolv operations, we have kept an existing ares
channel open. This seems unreliable as reported in #18216.
To get reliable behaviour, always destroy the ares channel on async
shutdown and create a new one on demand.

Closes#18217
The GlobalConfig only exists in a single instance and it has worked like
this since the dawn of time. It is about time we stop passing around
pointers to what was already essentially a global object and instead
just use a... global.
It simplifies things.
Closes#18213
By micromanaging the project dependency and its inclusion into the test
project. It feels like an awkward construct, but perhaps better than
nothing.
It's also fragile because it's a static build with no assistance from
the external project (curl in this case). Mitigated in test by disabling
all dependencies and some features.
Since there is no special core cmake logic to be tested here, in CI
the test is tested really. To keep CI jobs at minimum, only add 3 of
them, taking 42s in total. (All 6 would take 270s.)

curl_easy_reset() did not reset the `rewind_read` flag. This caused any
handles that previously had a CURLE_SEND_FAIL_REWIND error to get stuck
with that error, failing any subsequent requests, even if they didn't
have any body at all.
Verified in test 3034
Fixes#18206Closes#18207
The splay tree is a tree where each easy handle can be added *once*. The
expire time for that node is the closest expire time for that easy
handle.
Easy handles can however have more expire times queued up, so when the
node is removed from the splay tree because it is the next in line to
take care of, we must check if there is another expire time in the queue
and then add the node back into the splay.
Failing to do the later part, the calling of add_next_timeout after
Curl_splaygetbest, would leave the state.expiretime on the previous time
stamp, which when could make the next call to Curl_splaygetbest use the
wrong time stamp and get a wrong node out, causing trouble.

Closes#18201
Make variants for transfers that send/receive or do both with just the
parameters they need. Split out the shutdown setting into a separate
function. Only FTP bothers with that.
Closes#18203
- assert instead of printing "internal error" for unlikely events
- avoid allocating the main struct
- convert globerror() from macro to function
- renames to shorter and clearer names
- malloc + copy => memdup0
- change buffer handling to dynbuf
- realloc to handle more globs, but use less memory for few
Closes#18198
The `connectdata` members `sockfd` and `writesockfd` needed to by either
CURL_SOCKET_BAD or a copy of one of `conn->sock[2]`. When equal to one,
that index was used to send/recv/poll the proper socket or connection
filter chain.
Replace those with `send_idx` and `recv_idx` which are either -1, 0 or 1
to indicate which socket/filter to send/receive on.
Closes#18179
When a HTTP version has been negotiated via ALPN, set the member
`conn->httpversion_seen` accordingly. This allows pending transfers to
reuse multiplexed http connections before the response to the first
transfer has arrived.

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'.
Previously an attempt was made in #12406 by Björn Stenberg that was
ultimately never merged.

In WebAssembly, using `TCP_NODELAY` fails with:
```
* Could not set TCP_NODELAY: Protocol not available
```
Add a new feature macro in `curl_setup.h` telling whether `TCP_NODELAY`
is known to be supported at runtime, when defined at compile-time.
Keep `TCP_NODELAY` guards at their current positions to ensure the
necessary headers (e.g. `netinet/tcp.h` and `netinet/in.h`) define it.

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".

`getsock()` calls operated on a global limit that could
not be configure beyond 16 sockets. This is no longer adequate
with the new happy eyeballing strategy.
Instead, do the following:
- make `struct easy_pollset` dynamic. Starting with
a minimal room for two sockets, the very common case,
allow it to grow on demand.
- replace all protocol handler getsock() calls with pollsets
and a CURLcode to return failures
- add CURLcode return for all connection filter `adjust_pollset()`
callbacks, since they too can now fail.
- use appropriately in multi.c and multi_ev.c
- fix unit2600 to trigger pollset growth
Closes#18164
