Add protocol.h and protocol.c containing all about libcurl's
known URI schemes and their protocol handlers (so they exist).
Moves the scheme definitions from the various sources files into
protocol.c. Schemes are known and used, even of the protocol
handler is not build or just not implemented at all.
Closes#20906
This allows builds know about all schemes - but only have the protocol
implementations for those actually built-in.
It further allows multiple protocols to reuse the same protocol setup
and functions for both TLS and non-TLS implementations instead of
needing two (or more) structs.
The scheme information is now in 'struct Curl_scheme' and all the
function pointers for each scheme/protocol implementation are in struct
Curl_protocol.
The URL API now always work with all known protocols.

It was accidentally broken in commit 0f4c439fc7, shipped since
8.8.0 (May 2024) and yet not a single person has noticed or reported,
indicating that we might as well drop support for FTP Kerberos.
Krb5 support was added in 54967d2a3a (July 2007), and we have
been carrying the extra license information around since then for this
code. This commit removes the last traces of that code and thus we can
remove the extra copyright notices along with it.

Allow prequotes to be sent after curl has changed the working directory,
just before the listing command if the URL is a directory.

Follow-up to 1485e892 which changed the order of some struct members to
reduce struct size.
Closes https://github.com/curl/curl/pull/16538
Further testing with timeouts in event based processing revealed that
our current shutdown handling in the connection pool was not clear
enough. Graceful shutdowns can only happen inside a multi handle and it
was confusing to track in the code which situation actually applies. It
seems better to split the shutdown handling off and have that code
always be part of a multi handle.
Add `cshutdn.[ch]` with its own struct to maintain connections being
shut down. A `cshutdn` always belongs to a multi handle and uses that
for socket/timeout monitoring.
The `cpool`, which can be part of a multi or share, either passes
connections to a `cshutdn` or terminates them with a one-time, best
effort.
Add an `admin` easy handle to each multi and share. This is used to
perform all maintenance operations where no "real" easy handle is
available. This solves the problem that the multi admin handle requires
some additional initialisation (e.g. timeout list).
The share needs its admin handle as it is often cleaned up when no other
transfer or multi handle exists any more. But we need a `data` in almost
every call.
Fix file:// handling of errors when adding a new connection to the pool.
Changes in `curl` itself:
- for parallel transfers, do not set a connection pool in the share,
rely on the multi's connection pool instead. While not a requirement
for the new `cshutdn` to work, this is
a) helpful in testing to trigger graceful shutdowns
b) a broader code coverage of libcurl via the curl tool
- on test_event with uv, cleanup the multi handle before returning from
parallel_event(). The uv struct is on the stack, cleanup of the multi
later will crash when it tries to register sockets. This is a "eat
your own dogfood" related fix.
Closes#16508

Add licensing and copyright information for all files in this repository. This
either happens in the file itself as a comment header or in the file
`.reuse/dep5`.
This commit also adds a Github workflow to check pull requests and adapts
copyright.pl to the changes.

- Reorder some internal struct members so that less padding is used.
This is an attempt at saving a bit of space by packing some structs
(using pahole to find the holes) where it might make sense to do
so without losing readability.
I.e., I tried to avoid separating fields that seem grouped
together (like the cwd... fields in struct ftp_conn for instance).
Also abstained from touching fields behind conditional macros as
that quickly can get complicated.
Closes https://github.com/curl/curl/pull/6483
... in most cases instead of 'struct connectdata *' but in some cases in
addition to.
- We mostly operate on transfers and not connections.
- We need the transfer handle to log, store data and more. Everything in
libcurl is driven by a transfer (the CURL * in the public API).
- This work clarifies and separates the transfers from the connections
better.
- We should avoid "conn->data". Since individual connections can be used
by many transfers when multiplexing, making sure that conn->data
points to the current and correct transfer at all times is difficult
and has been notoriously error-prone over the years. The goal is to
ultimately remove the conn->data pointer for this reason.
Closes#6425
These two files were always tightly connected and it was hard to
understand what went into which. This also allows us to make the
ftpsend() function static (moved from ftp.c).
Removed security.c
Renamed curl_sec.h to krb5.h
Closes#5987
- no need to have them protocol specific
- no need to set pointers to them with the Curl_setup_transfer() call
- make Curl_setup_transfer() operate on a transfer pointer, not
connection
- switch some counters from long to the more proper curl_off_t type
Closes#3627
... it no longer takes printf() arguments since it was only really taken
advantage by one user and it was not written and used in a safe
way. Thus the 'f' is removed from the function name and the proto is
changed.
Although the current code wouldn't end up in badness, it was a risk that
future changes could end up springf()ing too large data or passing in a
format string inadvertently.
... and make sure we can connect the data connection to a host name that
is longer than 48 bytes.
Also simplifies the code somewhat by re-using the original host name
more, as it is likely still in the DNS cache.

This is a regression since the switch to always-multi internally
c43127414d.
Test 1316 was modified since we now clearly call the Curl_client_write()
function when doing the LIST transfer part and then the
handler->protocol says FTP and ftpc.transfertype is 'A' which implies
text converting even though that the response is initially a HTTP
CONNECT response in this case.

First off the timeout for accepting a server connect back must of course
respect a global timeout. Then the timeleft function is only used by ftp
code so it was moved to ftp.c and made static.
"wait_data_conn" was added to the connectionbits in commit c834213ad5 for
handling active FTP connections but as it is purely FTP specific and now
only ever accessed by ftp.c I moved it into the FTP connection struct.
