As of commit 54e7475, these flags would only be set when using a new
credential handle. When re-using an existing credential handle, the
flags would not be set.
Closes https://github.com/curl/curl/pull/7051
The Curl_resolv() had special code (when built in debug mode) for when
resolving the host name "LocalHost" (using that exact casing). It would
then get the host name from the --interface option instead.
This development-only feature was not used by anything (anymore) and we
have the --resolve feature if we want to play similar tricks properly
going forward.
Closes#7044
Otherwise the old value would linger from a previous use and would mess
up the network speed cap logic.

Writing the cookie file has multiple error conditions, and was using an
int with magic numbers to report the different error (which in turn were
disregarded anyways). This moves reporting to use a CURLcode value.

strstore() is defined as a strdup which ensures to free the target
pointer before duping the source char * into it. Make use of it in
two more cases where it can simplify the code.
Comments in the cookie code were a bit all over the place in terms of
style and wording. This takes a stab at cleaning them up by keeping to
a single style and overall shape. Some comments are moved a little and
some removed alltogether due to being redundant. No functional changes
have been made,
This is considered not harmful as a following http2_recv shall be
called very soon.
This is considered helpful in the specific situation where some
servers (e.g. nghttpx v1.43.0) may fulfill stream 1 immediately
following the return of HTTP status 101, other than waiting for
the client-side connection preface to arrive.
Fixes#7036Closes#7040
Assumed to be a minor coding style improvement with no behavior change.
A modern compiler is expected to have the calculation optimized during
compilation. It may be deemed okay even if that's not the case, since
the added overhead is considered very low.
Closes#7032
Also added 'CURL_SMALLSENDS' to make Curl_write() send short packets,
which helped verifying this even more.
Add test 363 to verify.

Previously this logic would cap the send to CURL_MAX_WRITE_SIZE bytes,
but for the situations where a larger upload buffer has been set, this
function can benefit from sending more bytes. With default size used,
this does the same as before.
Also changed the storage of the size to an 'unsigned int' as it is not
allowed to be set larger than 2M.
Also added cautions to the man pages about changing buffer sizes in
run-time.
Closes#7022
A reused transfer handle could otherwise reuse the previous leftover
buffer and havoc would ensue.

Previously, settting only the max allowed TLS version, leaving the
minimum one at default, didn't actually set it and left it to default
(TLS 1.3) too!
As a bonus, this change also removes the dead code handling of SSLv3
since that version can't be set anymore (since eff614fb02).

Since openldap itself uses that prefix and with OpenĹDAP 2.5.4 (at
least) there's a symbol collision because of that.
The private functions now use the 'oldap_' prefix where it previously
used 'ldap_'.

... as they're checked for in the configure script and are used by
source code.
Removed checks for perror, setvbuf and strlcat since those defines are
not checked for in source code.
Bonus: removed HAVE_STRLCPY from a few config-*.h files since that
symbol is not used in source code.
Closes#6997
... to avoid memory leaks!
libssh2 is tricky as we have to deal with the non-blockiness even in
close and shutdown cases. In the cases when we shutdown after a timeout
already expired, it is crucial that curl doen't let the timeout abort
the shutdown process as that then leaks memory!

Fixes#6990
When a TLS server requests a client certificate during handshake and
none can be provided, libcurl now returns this new error code
CURLE_SSL_CLIENTCERT
Only supported by Secure Transport and OpenSSL for TLS 1.3 so far.

connection). Function pipe_ssloverssl return always 0, when proxy is not
used.
Closes#6981
This abstracts across the two HTTP/2 backends: nghttp2 and Hyper.
Add our own define for the "h2" ALPN protocol, so TLS backends can use
it without depending on a specific HTTP backend.
Closes#6959
Previously if a caller set CURLOPT_WRITEFUNCTION but did not set a
CURLOPT_HEADERDATA buffer, Hyper would still attempt to write headers to
the data->set.writeheader header buffer, even though it is null. This
led to NPE segfaults attempting to use libcurl+Hyper with Git, for
example.
Instead, process the client write for the status line using the same
logic we use to process the client write for the later HTTP headers,
which contains the appropriate guard logic. As a side benefit,
data->set.writeheader is now only read in one file instead of two.
