By making sure we set state.upload based on the set.method value and not
independently as set.upload, we reduce confusion and mixup risks, both
internally and externally.

An optimized build runs one of my benchmark URL parsing programs ~41%
faster using this branch. (compared against the shipped 7.88.1 library
in Debian)

return error if this option is used other backends.

- ftp: sort ftp_conn struct entries on size

- 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
The only TLS auth type libcurl ever supported is SRP and that is the
default type. Since nobody ever sets any other type, there is no point
in wasting space to store the set type and code to check the type.
If TLS auth is used, SRP is now implied.
Closes#10181
Refactoring of connection setup and happy eyeballing. Move
nghttp2. ngtcp2, quiche and msh3 into connection filters.
- eyeballing cfilter that uses sub-filters for performing parallel connects
- socket cfilter for all transport types, including QUIC
- QUIC implementations in cfilter, can now participate in eyeballing
- connection setup is more dynamic in order to adapt to what filter did
really connect. Relevant to see if a SSL filter needs to be added or
if SSL has already been provided
- HTTP/3 test cases similar to HTTP/2
- multiuse of parallel transfers for HTTP/3, tested for ngtcp2 and quiche
- Fix for data attach/detach in VTLS filters that could lead to crashes
during parallel transfers.
- Eliminating setup() methods in cfilters, no longer needed.
- Improving Curl_conn_is_alive() to replace Curl_connalive() and
integrated ssl alive checks into cfilter.
- Adding CF_CNTRL_CONN_INFO_UPDATE to tell filters to update
connection into and persist it at the easy handle.
- Several more cfilter related cleanups and moves:
- stream_weigth and dependency info is now wrapped in struct
Curl_data_priority
- Curl_data_priority members depend is available in HTTP2|HTTP3
- Curl_data_priority members depend on NGHTTP2 support
- handling init/reset/cleanup of priority part of url.c
- data->state.priority same struct, but shallow copy for compares only
- PROTOPT_STREAM has been removed
- Curl_conn_is_mulitplex() now available to check on capability
- Adding query method to connection filters.
- ngtcp2+quiche: implementing query for max concurrent transfers.
- Adding is_alive and keep_alive cfilter methods. Adding DATA_SETUP event.
- setting keepalive timestamp on connect
- DATA_SETUP is called after the connection has been completely
setup (but may not connected yet) to allow filters to initialize
data members they use.
- there is no socket to be had with msh3, it is unclear how select
shall work
- manual test via "curl --http3 https://curl.se" fail with "empty
reply from server".
- Various socket/conn related cleanups:
- Curl_socket is now Curl_socket_open and in cf-socket.c
- Curl_closesocket is now Curl_socket_close and in cf-socket.c
- Curl_ssl_use has been replaced with Cur_conn_is_ssl
- Curl_conn_tcp_accepted_set has been split into
Curl_conn_tcp_listen_set and Curl_conn_tcp_accepted_set
with a clearer purpose
Closes#10141
- source_quote, source_prequote and source_postquote have not been used since
5e0d9aea3; September 2006
- make several fields conditional on proxy support
- make three quote struct fields conditional on FTP || SSH
- make 'mime_options' depend on MIME
- make trailer_* fields depend on HTTP
- change 'gssapi_delegation' from long to unsigned char
- make 'localportrange' unsigned short instead of int
- conn->trailer now depends on HTTP
Closes#10147
The cookiefile entries are set into the handle and should remain set for
the lifetime of the handle so that duplicating it also duplicates the
list. Therefore, the struct field is moved from 'state' to 'set'.

- general construct/destroy in connectdata
- default implementations of callback functions
- connect: cfilters for connect and accept
- socks: cfilter for socks proxying
- http_proxy: cfilter for http proxy tunneling
- vtls: cfilters for primary and proxy ssl
- change in general handling of data/conn
- Curl_cfilter_setup() sets up filter chain based on data settings,
if none are installed by the protocol handler setup
- Curl_cfilter_connect() boot straps filters into `connected` status,
used by handlers and multi to reach further stages
- Curl_cfilter_is_connected() to check if a conn is connected,
e.g. all filters have done their work
- Curl_cfilter_get_select_socks() gets the sockets and READ/WRITE
indicators for multi select to work
- Curl_cfilter_data_pending() asks filters if the have incoming
data pending for recv
- Curl_cfilter_recv()/Curl_cfilter_send are the general callbacks
installed in conn->recv/conn->send for io handling
- Curl_cfilter_attach_data()/Curl_cfilter_detach_data() inform filters
and addition/removal of a `data` from their connection
- adding vtl functions to prevent use of Curl_ssl globals directly
in other parts of the code.

Currently only the OpenSSL backend implements support for
caching certificate stores.

Even though `PICKY_COMPILER=ON` is the default, warnings were not
enabled when using llvm/clang, because `CMAKE_COMPILER_IS_CLANG` was
always false (in my tests at least).
This is the single use of this variable in curl, and in a different
place we already use `CMAKE_C_COMPILER_ID MATCHES "Clang"`, which works
as expected, so change the condition to use that instead.
Also fix the warnings uncovered by the above:
- lib: add casts to silence clang warnings
- schannel: add casts to silence clang warnings in ALPN code
Assuming the code is correct, solve the warnings with a cast.
This particular build case isn't CI tested.
There is a chance the warning is relevant for some platforms, perhaps
Windows 32-bit ARM7.
Closes#9783
The introduction of CURL_DISABLE_MIME came with some additional bugs:
- Disabled MIME is compiled-in anyway if SMTP and/or IMAP is enabled.
- CURLOPT_MIMEPOST, CURLOPT_MIME_OPTIONS and CURLOPT_HTTPHEADER are
conditioned on HTTP, although also needed for SMTP and IMAP MIME mail
uploads.
In addition, the CURLOPT_HTTPHEADER and --header documentation does not
mention their use for MIME mail.
This commit fixes the problems above.
Closes#9610
This also returns error CURLE_UNSUPPORTED_PROTOCOL rather than
CURLE_BAD_FUNCTION_ARGUMENT when a listed protocol name is not found.
A new schemelen parameter is added to Curl_builtin_scheme() to support
this extended use.
Note that disabled protocols are not recognized anymore.
Tests adapted accordingly.
Closes#9472
This internal-use-only storage type can be bumped to a curl_off_t once
we need to use bit 32 as the previous 'unsigned int' can no longer hold
them all then.
The websocket protocols take bit 30 and 31 so they are the last ones
that fit within 32 bits - but cannot properly be exported through APIs
since those use *signed* 32 bit types (long) in places.
Closes#9481
Next Protocol Negotiation is a TLS extension that was created and used
for agreeing to use the SPDY protocol (the precursor to HTTP/2) for
HTTPS. In the early days of HTTP/2, before the spec was finalized and
shipped, the protocol could be enabled using this extension with some
servers.
curl supports the NPN extension with some TLS backends since then, with
a command line option `--npn` and in libcurl with
`CURLOPT_SSL_ENABLE_NPN`.
HTTP/2 proper is made to use the ALPN (Application-Layer Protocol
Negotiation) extension and the NPN extension has no purposes
anymore. The HTTP/2 spec was published in May 2015.
Today, use of NPN in the wild should be extremely rare and most likely
totally extinct. Chrome removed NPN support in Chrome 51, shipped in
June 2016. Removed in Firefox 53, April 2017.
