The variable had a few different names. Now try to use 'clientp'
consistently for all man pages using a custom pointer set by the
application.

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.
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).
Scorecard with Caddy.
- configure can be run with `--with-test-caddy=path` to specify which caddy to use for testing
- tests/tests-httpd/scorecard.py now measures download speeds with caddy
pytest improvements
- adding Makfile to clean gen dir
- adding nghttpx rundir creation on start
- checking httpd version 2.4.55 for test_05 cases where it is needed. Skipping with message if too old.
- catch exception when checking for caddy existance on system.
Closes#10349
The documentation of `%{header_json}` missed to mention since which
version this variable for `--write-out` is present.
Based on commit https://github.com/curl/curl/commit/4133a69f2daa476bb
we can determine from the tags were this commit is present that the
first version to include it was `7.83.0`.
This could be also checked with:
`git tag --contains 4133a69f2daa476bb6d902687f1dd6660ea9c3c5`
Closes#10395
- Clarify that in Windows batch files the % must be escaped as %%, and
at the command prompt it cannot be escaped which could lead to
incorrect expansion.
Prior to this change the doc implied % must be escaped as %% in win32
always.
---
Examples showing how a write-out argument is received by curl:
If curl --write-out "%{http_code}" is executed in a batch file:
{http_code}
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:
%%{http_code}
At the command prompt something like "%{speed_download}%{http_code}"
would first be parsed by the command interpreter as %{speed_download}%
and would be expanded as environment variable {speed_download} if it
existed, though that's highly unlikely since Windows environment names
don't use braces.

Closes https://github.com/curl/curl/pull/10337
Bump the limit from 512K. There might be reasons for applications using
h3 to set larger buffers and there is no strong reason for curl to have
a very small maximum.
Ref: https://curl.se/mail/lib-2023-01/0026.htmlCloses#10256
Because only the libssh2 backend not supports it and thus this should
return error if this option is used other backends.

Closes#10255
- Warn that in Windows if libcurl is running from a DLL and if
CURLOPT_HEADERDATA is set then CURLOPT_WRITEFUNCTION or
CURLOPT_HEADERFUNCTION must be set as well, otherwise the user may
experience crashes.
We already have a similar warning in CURLOPT_WRITEDATA. Basically, in
Windows libcurl could crash writing a FILE pointer that was created by
a different C runtime. In Windows each DLL that is part of a program may
or may not have its own C runtime.

- they are mostly pointless in all major jurisdictions
- many big corporations and projects already don't use them
- saves us from pointless churn
- git keeps history for us
- the year range is kept in COPYING
checksrc is updated to allow non-year using copyright statements
Closes#10205
Ref: #10163
- This is a niche TLS library, only running on some IBM systems
- no regular curl contributors use this backend
- no CI builds use or verify this backend
- gskit, or the curl adaption for it, lacks many modern TLS features
making it an inferior solution
- build breakages in this code take weeks or more to get detected
- fixing gskit code is mostly done "flying blind"
Closes#10201
- it does not add a lot of value
- we do not test-build it to verify because of its dependencies
- unclear for what GTK versions it works or not
