- the data needs to be "line-based" anyway since it's also passed to the
debug callback/application
- it makes infof() work like failf() and consistency is good
- there's an assert that triggers on newlines in the format string
- Also removes a few instances of "..."
- Removes the code that would append "..." to the end of the data *iff*
it was truncated in infof()

From Apples documentation on SCDynamicStoreCopyProxies, "Return Value: A
dictionary of key-value pairs that represent the current internet proxy
settings, or NULL if no proxy settings have been defined or if an error
occurred. You must release the returned value."
Failure to release the returned value of SCDynamicStoreCopyProxies can
result in a memory leak.

- Check the return code to Curl_inet_pton() in two instances, even
though we know the input is valid so the functions won't fail.
- Clear the 'struct sockaddr_in' struct before use so that the
'sin_zero' field isn't left uninitialized.

Closes#7163
Resolving the case insensitive host name 'localhost' now returns the
addresses 127.0.0.1 and (if IPv6 is enabled) ::1 without using any
resolver.
This removes the risk that users accidentally resolves 'localhost' to
something else. By making sure 'localhost' is always local, we can
assume a "secure context" for such transfers (for cookies etc).
Closes#7039
Also, use a single function library-wide for detecting if a given hostname is

Fixes#7146Closes#7149
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
This was previously defined by the obsolete AC_TYPE_SIGNAL macro,
which was removed in 2682e5f5. The deprecation text says
> Your code may safely assume C89 semantics that RETSIGTYPE is void.
So, remove it and just use void instead.

- Define Curl_resolver_error function only when USE_CURL_ASYNC.
Prior to this change building curl without an asynchronous resolver
backend (c-ares or threaded) and without DoH (DNS-over-HTTPS, which is
also asynchronous but independent of resolver backend) would cause a
build error since Curl_resolver_error is called by and evaluates
variables only available in asynchronous builds.

- Guard some Curl_async accesses with USE_CURL_ASYNC instead of
!CURLRES_SYNCH.
This is another follow-up to 8335c64 which moved the async struct from
the connectdata struct into the Curl_easy struct. A previous follow-up
6cd167a fixed building for sync resolver by guarding some async struct
accesses with !CURLRES_SYNCH. The problem is since DOH (DNS-over-HTTPS)
is available as an asynchronous secondary resolver the async struct may
be used even when libcurl is built for the sync resolver. That means
that CURLRES_SYNCH and USE_CURL_ASYNC may be defined at the same time.
Closes https://github.com/curl/curl/pull/6603
... 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
We currently use both spellings the british "behaviour" and the american
"behavior". However "behavior" is more used in the project so I think
it's worth dropping the british name.

Extend the syntax of CURLOPT_RESOLVE strings: allow using a '+' prefix
(similar to the existing '-' prefix for removing entries) to add
DNS cache entries that will time out just like entries that are added
by libcurl itself.
Append " (non-permanent)" to info log message in case a non-permanent
entry is added.
Adjust relevant comments to reflect the new behavior.
Adjust documentation.
Extend unit1607 to test the new functionality.

More connection cache accesses are protected by locks.
CONNCACHE_* is a beter prefix for the connection cache lock macros.
Curl_attach_connnection: now called as soon as there's a connection
struct available and before the connection is added to the connection
cache.
Curl_disconnect: now assumes that the connection is already removed from
the connection cache.

The code was duplicated in the various resolver backends.
Also, it was called after the call to `Curl_ipvalid`, which matters in
case of `CURLRES_IPV4` when called from `connect.c:bindlocal`. This
caused test 1048 to fail on classic MinGW.
The code ignores `conn->ip_version` as done previously in the
individual resolver backends.
Move the call to the `resolver_start` callback up to appease test 655,
which wants it to be called also for literal addresses.
Closes https://github.com/curl/curl/pull/4798
It was used (intended) to pass in the size of the 'socks' array that is

This adds support for wildcard hosts in CURLOPT_RESOLVE. These are
try-last so any non-wildcard entry is resolved first. If specified,
any host not matched by another CURLOPT_RESOLVE config will use this
as fallback.
Example send a.com to 10.0.0.1 and everything else to 10.0.0.2:
curl --resolve *:443:10.0.0.2 --resolve a.com:443:10.0.0.1 \
https://a.comhttps://b.com
This is probably quite similar to using:
--connect-to a.com:443:10.0.0.1:443 --connect-to :443:10.0.0.2:443

This patch adds CURLOPT_DNS_SHUFFLE_ADDRESSES to explicitly request
shuffling of IP addresses returned for a hostname when there is more
than one. This is useful when the application knows that a round robin
approach is appropriate and is willing to accept the consequences of
potentially discarding some preference order returned by the system's
implementation.
