... but instead use a private alternative that points to the "driving
transfer" from the connection. We set the "user data" associated with
the connection to be the connectdata struct, but when we drive transfers
the code still needs to know the pointer to the transfer. We can change
the user data to become the Curl_easy handle, but with older nghttp2
version we cannot dynamically update that pointer properly when
different transfers are used over the same connection.
Closes#6520
HTTP auth "accidentally" worked before this cleanup since the code would
always overwrite the connection credentials with the credentials from
the most recent transfer and since HTTP auth is typically done first
thing, this has not been an issue. It was still wrong and subject to
possible race conditions or future breakage if the sequence of functions
would change.
The data.set.str[] strings MUST remain unmodified exactly as set by the
user, and the credentials to use internally are instead set/updated in
state.aptr.*
Added test 675 to verify different credentials used in two requests done
over a reused HTTP connection, which previously behaved wrongly.
Fixes#6542Closes#6545
Rename it to 'httpwant' and make a cloned field in the state struct as
well for run-time updates.
Also: refuse non-supported HTTP versions. Verified with test 129.
Closes#6585
... and make sure the code never updates 'set.prefer_ascii' as it breaks
handle reuse which should use the setting as the user specified it.
Added test 1569 to verify: it first makes an FTP transfer with ';type=A'
and then another without type on the same handle and the second should
then use binary. Previously, curl failed this.
Closes#6578
... 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
When doing a request with a request body expecting a 401/407 back, that
initial request is sent with a zero content-length. Test 177 and more.
Closes#6424
... so that Retry-After and other meta-content can still be used.
Added 1634 to verify. Adjusted test 194 and 281 since --fail now also
includes the header-terminating CRLF in the output before it exits.
Fixes#6408Closes#6409
When the initial request isn't possible to send in its entirety, the
remainder of request would be delivered to the debug callback as data
and would wrongly be counted internally as body-bytes sent.
Extended test 1295 to verify.

Closes#5896
... when the chunked framing was added, the size of the "body part" of
the data was calculated wrongly so the debug callback would get told a
header chunk a few bytes too big that would also contain the first few
bytes of the request body.

Provide the HTTP method that was used on the latest request, which might

Updated terminology in docs, comments and phrases to refer to C strings
as "null-terminated". Done to unify with how most other C oriented docs
refer of them and what users in general seem to prefer (based on a

Fixes#5598Closes#5608
Since the connection can be used by many independent requests (using
HTTP/2 or HTTP/3), things like user-agent and other transfer-specific
data MUST NOT be kept connection oriented as it could lead to requests
getting the wrong string for their requests. This struct data was
lingering like this due to old HTTP1 legacy thinking where it didn't
mattered..

When the method is updated inside libcurl we must still not change the

A common set of functions instead of many separate implementations for
creating buffers that can grow when appending data to them. Existing
functionality has been ported over.
In my early basic testing, the total number of allocations seem at
roughly the same amount as before, possibly a few less.
See docs/DYNBUF.md for a description of the API.
Closes#5300
In a debug build, settting the environment variable "CURL_SMALLREQSEND"
will make the first HTTP request send not send more bytes than the set
amount, thus ending up verifying that the logic for handling a split
HTTP request send works correctly.
