- adding tests using very large passwords in auth
- fixes general http sending to treat h3 like h2, and
not like http1.1

proxy tunneling tests
Closes#11368
- Use CURL_FORMAT_CURL_OFF_T where %zd was erroneously used for some
curl_off_t variables.
- Use %zu where %zd was erroneously used for some size_t variables.
Prior to this change some of the Windows CI tests were failing because
in Windows 32-bit targets have a 32-bit size_t and a 64-bit curl_off_t.
When %zd was used for some curl_off_t variables then only the lower
32-bits was read and the upper 32-bits would be read for part or all of
the next specifier.

- add an `id` long to Curl_easy, -1 on init
- once added to a multi (or its own multi), it gets
a non-negative number assigned by the connection cache
- `id` is unique among all transfers using the same
cache until reaching LONG_MAX where it will wrap
around. So, not unique eternally.
- CURLINFO_CONN_ID returns the connection id attached to
data or, if none present, data->state.lastconnect_id
- variables and type declared in tool for write out
Closes#11185
- ngtcp2 v0.16.0 asserts that timestamps passed to its function

- Use a context shared between ingress/egress operations that
uses a shared timestamp, regularly updated during calls.
Closes#11288
Aka "jumbo" or "amalgamation" builds. It means to compile all sources
per target as a single C source. This is experimental.
You can enable it by passing `-DCMAKE_UNITY_BUILD=ON` to cmake.
It requires CMake 3.16 or newer.
It makes builds (much) faster, allows for better optimizations and tends
to promote less ambiguous code.
Also add a new AppVeyor CI job and convert an existing one to use
"unity" mode (one MSVC, one MinGW), and enable it for one macOS CI job.
Fix related issues:
- add missing include guard to `easy_lock.h`.
- rename static variables and functions (and a macro) with names reused
across sources, or shadowed by local variables.
- add an `#undef` after use.
- add a missing `#undef` before use.
- move internal definitions from `ftp.h` to `ftp.c`.
- `curl_memory.h` fixes to make it work when included repeatedly.
- stop building/linking curlx bits twice for a static-mode curl tool.
These caused doubly defined symbols in unity builds.
- silence missing extern declarations compiler warning for ` _CRT_glob`.
- fix extern declarations for `tool_freq` and `tool_isVistaOrGreater`.
- fix colliding static symbols in debug mode: `debugtime()` and
`statename`.
- rename `ssl_backend_data` structure to unique names for each
TLS-backend, along with the `ssl_connect_data` struct member
referencing them. This required adding casts for each access.
- add workaround for missing `[P]UNICODE_STRING` types in certain Windows
builds when compiling `lib/ldap.c`. To support "unity" builds, we had
to enable `SCHANNEL_USE_BLACKLISTS` for Schannel (a Windows
`schannel.h` option) _globally_. This caused an indirect inclusion of
Windows `schannel.h` from `ldap.c` via `winldap.h` to have it enabled
as well. This requires `[P]UNICODE_STRING` types, which is apperantly
not defined automatically (as seen with both MSVS and mingw-w64).
This patch includes `<subauth.h>` to fix it.

- ngtcp2 and quiche implementations relied on the DONE_SEND event
to forward the EOF for uploads to the libraries. This often
result in a last 0 length EOF data. Tracking the amount of
data left to upload allows EOF indication earlier.

receive the initial upload DATA without EOF and returned
a 400 Bad Request

- compiler analyzer did not include the call context for this
static function where the condition had already been checked.
- eleminating the problem by making stream a call parameter
Fixes#11147Closes#11151
This works around #11138, by doubling the limit, and should be a
relatively safe fix.
Ideally the buffer would grow as needed and there would be no need for a
limit? But that might be follow-up material.

Out of 415 labels throughout the code base, 86 of those labels were
not at the start of the line. Which means labels always at the start of
the line is the favoured style overall with 329 instances.
Out of the 86 labels not at the start of the line:
* 75 were indented with the same indentation level of the following line
* 8 were indented with exactly one space
* 2 were indented with one fewer indentation level then the following
line
* 1 was indented with the indentation level of the following line minus
three space (probably unintentional)

- `drain` was used by http/2 and http/3 implementations to indicate
that the transfer requires send/recv independant from its socket
poll state. Intended as a counter, it was used as bool flag only.
- a similar mechanism exists on `connectdata->cselect_bits` where
specific protocols can indicate something similar, only for the
whole connection.
- `cselect_bits` are cleard in transfer.c on use and, importantly,
also set when the transfer loop expended its `maxloops` tries.
`drain` was not cleared by transfer and the http2/3 implementations
had to take care of that.
- `dselect_bits` is cleared *and* set by the transfer loop. http2/3
does no longer clear it, only set when new events happen.
This change unifies the handling of socket poll overrides, extending
`cselect_bits` by a easy handle specific value and a common treatment in
transfers.
Closes#11005
- with `--proxy-http2` allow h2 ALPN negotiation to
forward proxies
- applies to http: requests against a https: proxy only,
as https: requests will auto-tunnel
- adding a HTTP/1 request parser in http1.c
- removed h2h3.c
- using new request parser in nghttp2 and all h3 backends
- adding test 2603 for request parser
- adding h2 proxy test cases to test_10_*
scorecard.py: request scoring accidentally always run curl
with '-v'. Removed that, expect double numbers.
labeller: added http1.* and h2-proxy sources to detection
Closes#10967
- callbacks and filter methods might be invoked at unexpected
times, e.g. when the transfer's stream_ctx has not been initialized
yet or, more likely, has already been taken down.
- check for existance of stream_ctx in such places and return
an error or silently succeed the call.
Closes#10951
- remove NGHTTP2 members of `struct HTTP`
- add `void *h2_ctx` to `struct HTTP`
- add `void *h3_ctx` to `struct HTTP`
- separate h2/h3 pointers are needed for eyeballing
- manage local stream_ctx in http implementations
Closes#10877
- currently only on debug build and when env variable
CURL_PROXY_TUNNEL_H2 is present.
- will ALPN negotiate with the proxy server and switch
tunnel filter based on the protocol negotiated.
- http/1.1 tunnel code moved into cf-h1-proxy.[ch]
- http/2 tunnel code implemented in cf-h2-proxy.[ch]
- tunnel start and ALPN set remains in http_proxy.c
- moving all haproxy related code into cf-haproxy.[ch]
VTLS changes
- SSL filters rely solely on the "alpn" specification they
are created with and no longer check conn->bits.tls_enable_alpn.
- checks on which ALPN specification to use (or none at all) are
done in vtls.c when creating the filter.
Testing
- added a nghttpx forward proxy to the pytest setup that
speaks HTTP/2 and forwards all requests to the Apache httpd
forward proxy server.
- extending test coverage in test_10 cases
- adding proxy tests for direct/tunnel h1/h2 use of basic auth.
- adding test for http/1.1 and h2 proxy tunneling to pytest
Closes#10780
- ngtcp2: using bufq for recv stream data
- internal stream_ctx instead of `struct HTTP` members
for quiche, ngtcp2 and msh3
- no more QUIC related members in `struct HTTP`
- experimental use of recvmmsg(), disabled by default
- testing on my old debian box shows no throughput improvements.
- leaving it in, but disabled, for future revisit
- vquic: common UDP receive code for ngtcp2 and quiche
- vquic: common UDP send code for ngtcp2 and quiche
- added pytest skips for known msh3 failures
- fix unit2601 to survive torture testing
- quiche: using latest `master` from quiche and enabling large download
tests, now that key change is supported
- fixing test_07_21 where retry handling of starting a stream
was faulty
- msh3: use bufq for recv buffering headers and data
- msh3: replace fprintf debug logging with LOG_CF where possible
- msh3: force QUIC expire timers on recv/send to have more than
1 request per second served
Closes#10772
- make configure show on HTTP3 feature that both ngtcp2 and nghttp3
are in play
- define ENABLE_QUIC only when USE_NGTCP2 and USE_NGHTTP3 are defined
- add USE_NGHTTP3 in the ngtcp2 implementation
Fixes#10793Closes#10821
- use the defined, but so far not used, KEEP_SEND_HOLD bit for flow
control based suspend of sending in transfers.
Prior to this change KEEP_SEND_PAUSE bit was used instead, but that can
interfere with pausing streams from the user side via curl_easy_pause.

- add parameter to `conn_is_alive()` cfilter method that returns
if there is input data waiting on the connection
- refrain from re-using connnection from the cache that have

- adapt http/2 and http/3 alive checks to digest pending input
to check the connection state
- remove check_cxn method from openssl as that was just doing
what the socket filter now does.

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
- new functions and macros for cfilter debugging
- set CURL_DEBUG with names of cfilters where debug logging should be
enabled
