907520c4b9 progress callback: skip last callback update on errors
When an error has been detected, skip the final forced call to the
progress callback by making sure to pass the current return code
variable in the Curl_done() call in the CURLM_STATE_DONE state.

This avoids the "extra" callback that could occur even if you returned
error from the progress callback.

710f14edba handler: make 'protocol' always specified as a single bit
This makes the findprotocol() function work as intended so that libcurl
can properly be restricted to not support HTTP while still supporting
HTTPS - since the HTTPS handler previously set both the HTTP and HTTPS
bits in the protocol field.

This fixes --proto and --proto-redir for most SSL protocols.

This is done by adding a few new convenience defines that groups HTTP
and HTTPS, FTP and FTPS etc that should then be used when the code wants
to check for both protocols at once. PROTO_FAMILY_[protocol] style.

8ae35102c4 ConnectionExists: fix NTLM check for new connection
When the requested authentication bitmask includes NTLM, we cannot
re-use a connection for another username/password as we then risk
re-using NTLM (connection-based auth).

This has the unfortunate downside that if you include NTLM as a possible
auth, you cannot re-use connections for other usernames/passwords even
if NTLM doesn't end up the auth type used.

02fbc26d59 connect: Add connection delay to Happy Eyeballs.
This patch adds a 200ms delay between the first and second address
family socket connection attempts.

It also iterates over IP addresses in the order returned by the
system, meaning most dual-stack systems will try IPv6 first.

Additionally, it refactors the connect code, removing most code that
handled synchronous connects. Since all sockets are now non-blocking,
the logic can be made simpler.

This patch invokes two socket connect()s nearly simultaneously, and

There is a very slight IPv4 preference, in that if both sockets connect
simultaneously IPv4 is checked first and thus will win.

2f1a0bc0bf url: handle arbitrary-length username and password before '@'
libcurl quietly truncates usernames, passwords, and options from
before an '@' sign in a URL to 255 (= MAX_CURL_PASSWORD_LENGTH - 1)
characters to fit in fixed-size buffers on the stack.  Allocate a
buffer large enough to fit the parsed fields on the fly instead to
support longer passwords.

After this change, there are no more uses of MAX_CURL_OPTIONS_LENGTH
left, so stop defining that constant while at it.  The hardcoded max
username and password length constants, on the other hand, are still
used in HTTP proxy credential handling (which this patch doesn't
touch).

15f76bf7bb Curl_setopt: handle arbitrary-length username and password
libcurl truncates usernames, passwords, and options set with
curl_easy_setopt to 255 (= MAX_CURL_PASSWORD_LENGTH - 1) characters.
This doesn't affect the return value from curl_easy_setopt(), so from
the caller's point of view, there is no sign anything strange has
happened, except that authentication fails.

For example:

  # Prepare a long (300-char) password.
  s=0123456789; s=$s$s$s$s$s$s$s$s$s$s; s=$s$s$s;
  # Start a server.
  nc -l -p 8888 | tee out & pid=$!
  # Tell curl to pass the password to the server.
  curl --user me:$s http://localhost:8888 & sleep 1; kill $pid
  # Extract the password.
  userpass=$(
	awk '/Authorization: Basic/ {print $3}' <out |
	tr -d '\r' |
	base64 -d
  )
  password=${userpass#me:}
  echo ${#password}

Expected result: 300
Actual result: 255

The fix is simple: allocate appropriately sized buffers on the heap
instead of trying to squeeze the provided values into fixed-size
on-stack buffers.

36585b5395 netrc: handle longer username and password
libcurl truncates usernames and passwords it reads from .netrc to
LOGINSIZE and PASSWORDSIZE (64) characters without any indication to
the user, to ensure the values returned from Curl_parsenetrc fit in a
caller-provided buffer.

Fix the interface by passing back dynamically allocated buffers
allocated to fit the user's input.  The parser still relies on a
256-character buffer to read each line, though.

So now you can include an ~246-character password in your .netrc,
instead of the previous limit of 63 characters.

7cc00d9a83 FTP: when EPSV gets a 229 but fails to connect, retry with PASV
This is a regression as this logic used to work. It isn't clear when it
broke, but I'm assuming in 7.28.0 when we went all-multi internally.

This likely never worked with the multi interface. As the failed
connection is detected once the multi state has reached DO_MORE, the
Curl_do_more() function was now expanded somewhat so that the
ftp_do_more() function can request to go "back" to the previous state
when it makes another attempt - using PASV.

Added test case 1233 to verify this fix. It has the little issue that it
assumes no service is listening/accepting connections on port 1...

e4b733e3f1 HTTP proxy: insert slash in URL if missing
curl has been accepting URLs using slightly wrong syntax for a long
time, such as when completely missing as slash "http://example.org" or
missing a slash when a query part is given
"http://example.org?q=foobar".

curl would translate these into a legitimate HTTP request to servers,
although as was shown in bug #1206 it was not adjusted properly in the
cases where a HTTP proxy was used.

Test 1213 and 1214 were added to the test suite to verify this fix.

The test HTTP server was adjusted to allow us to specify test number in
the host name only without using any slashes in a given URL.

0f147887b0 Multiple pipelines and limiting the number of connections.
Introducing a number of options to the multi interface that
allows for multiple pipelines to the same host, in order to
optimize the balance between the penalty for opening new
connections and the potential pipelining latency.

Two new options for limiting the number of connections:

CURLMOPT_MAX_HOST_CONNECTIONS - Limits the number of running connections
to the same host. When adding a handle that exceeds this limit,
that handle will be put in a pending state until another handle is
finished, so we can reuse the connection.

CURLMOPT_MAX_TOTAL_CONNECTIONS - Limits the number of connections in total.
When adding a handle that exceeds this limit,
that handle will be put in a pending state until another handle is
finished. The free connection will then be reused, if possible, or
closed if the pending handle can't reuse it.

Several new options for pipelining:

CURLMOPT_MAX_PIPELINE_LENGTH - Limits the pipeling length. If a
pipeline is "full" when a connection is to be reused, a new connection
will be opened if the CURLMOPT_MAX_xxx_CONNECTIONS limits allow it.
If not, the handle will be put in a pending state until a connection is
ready (either free or a pipe got shorter).

CURLMOPT_CONTENT_LENGTH_PENALTY_SIZE - A pipelined connection will not
be reused if it is currently processing a transfer with a content
length that is larger than this.

CURLMOPT_CHUNK_LENGTH_PENALTY_SIZE - A pipelined connection will not
be reused if it is currently processing a chunk larger than this.

CURLMOPT_PIPELINING_SITE_BL - A blacklist of hosts that don't allow
pipelining.

CURLMOPT_PIPELINING_SERVER_BL - A blacklist of server types that don't allow
pipelining.

See the curl_multi_setopt() man page for details.

5a053ffe80 build: fix circular header inclusion with other packages
This commit renames lib/setup.h to lib/curl_setup.h and
renames lib/setup_once.h to lib/curl_setup_once.h.

Removes the need and usage of a header inclusion guard foreign
to libcurl. [1]

Removes the need and presence of an alarming notice we carried
in old setup_once.h [2]

----------------------------------------

1 - lib/setup_once.h used __SETUP_ONCE_H macro as header inclusion guard
    up to commit ec691ca3 which changed this to HEADER_CURL_SETUP_ONCE_H,
    this single inclusion guard is enough to ensure that inclusion of
    lib/setup_once.h done from lib/setup.h is only done once.

    Additionally lib/setup.h has always used __SETUP_ONCE_H macro to
    protect inclusion of setup_once.h even after commit ec691ca3, this
    was to avoid a circular header inclusion triggered when building a
    c-ares enabled version with c-ares sources available which also has
    a setup_once.h header. Commit ec691ca3 exposes the real nature of
    __SETUP_ONCE_H usage in lib/setup.h, it is a header inclusion guard
    foreign to libcurl belonging to c-ares's setup_once.h

    The renaming this commit does, fixes the circular header inclusion,
    and as such removes the need and usage of a header inclusion guard
    foreign to libcurl. Macro __SETUP_ONCE_H no longer used in libcurl.

2 - Due to the circular interdependency of old lib/setup_once.h and the
    c-ares setup_once.h header, old file lib/setup_once.h has carried
    back from 2006 up to now days an alarming and prominent notice about
    the need of keeping libcurl's and c-ares's setup_once.h in sync.

    Given that this commit fixes the circular interdependency, the need
    and presence of mentioned notice is removed.

    All mentioned interdependencies come back from now old days when
    the c-ares project lived inside a curl subdirectory. This commit
    removes last traces of such fact.

d021f2e8a0 Introducing a new persistent connection caching system using "bundles".
A bundle is a list of all persistent connections to the same host.
The connection cache consists of a hash of bundles, with the
hostname as the key.
The benefits may not be obvious, but they are two:

1) Faster search for connections to reuse, since the hash
   lookup only finds connections to the host in question.
2) It lays out the groundworks for an upcoming patch,
   which will introduce multiple HTTP pipelines.

This patch also removes the awkward list of "closure handles",
which were needed to send QUIT commands to the FTP server
when closing a connection.
Now we allocate a separate closure handle and use that
one to close all connections.

This has been tested in a live system for a few weeks, and of
course passes the test suite.

da82f59b69 CURLOPT_SSL_VERIFYHOST: stop supporting the 1 value
After a research team wrote a document[1] that found several live source
codes out there in the wild that misused the CURLOPT_SSL_VERIFYHOST
option thinking it was a boolean, this change now bans 1 as a value and
will make libcurl return error for it.

1 was never a sensible value to use in production but was introduced
back in the days to help debugging. It was always documented clearly
this way.

1 was never supported by all SSL backends in libcurl, so this cleanup
makes the treatment of it unified.

The report's list of mistakes for this option were all PHP code and
while there's a binding layer between libcurl and PHP, the PHP team has
decided that they have an as thin layer as possible on top of libcurl so
they will not alter or specifically filter a 'TRUE' value for this
particular option. I sympathize with that position.

bf6dc61967 verbose messages: fixed output of hostnames in re-used connections
I suspect this is a regression introduced in commit 207cf150, included
since 7.24.0.

Avoid showing '(nil)' as hostname in verbose output by making sure the
hostname fixup function is called early enough to set the pointers that
are used for this. The name data is set again for each request even for
re-used connections to handle multiple hostnames over the same
connection (like with proxy) or that the casing etc of the host name is
changed between requests (which has proven to be important at least once
in the past).

Test1011 was modified to use a redirect with a re-used a connection
since it then showed the bug and now lo longer does. There's currently
no easy way to have the test suite detect 'nil' texts in verbose ouputs
so no tests will detect if this problem gets reintroduced.

72b72fe8ed URL parse: reject numerical IPv6 addresses outside brackets
Roman Mamedov spotted (in
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=670126) that curl would
not complain when given a URL with an IPv6 numerical address without
brackets. It would simply cut off the last ":[hex]" part and thus not
work correctly.

That's a URL using an illegal syntax and now libcurl will instead return
a clear error code and error message detailing the error.

The above mentioned bug report claims this to be a regression but
libcurl does not guarantee functionality when given URLs that aren't
following the URL spec (RFC3986 mostly). I consider the fact that it
used to handle this differently a mere coincidence.

0cf0ab6f30 smtp_mail: Added support to MAIL FROM for the optional AUTH parameter
Added a new CURLOPT_MAIL_AUTH option that allows the calling program to
set the optional AUTH parameter in the MAIL FROM command.

When this option is specified and an authentication mechanism is used
to communicate with the mail server then the AUTH parameter will be
included in the MAIL FROM command. This is particularly useful when the
calling program is acting as a relay in a trusted environment and
performing server to server communication, as it allows the relaying
server to specify the address of the mailbox that was used to
authenticate and send the original email.

It will make libcurl to disable any work-arounds the underlying SSL

protocol versions.

This is a reaction to us unconditionally removing that behavior after
this security advisory:

... it did however cause a lot of programs to fail because of old
servers not liking this work-around. Now programs can opt to decrease

207cf15032 changed case: use new host name for subsequent HTTP requests
When a HTTP connection is re-used for a subsequent request without
proxy, it would always re-use the Host: header of the first request. As
host names are case insensitive it would make curl send another host
name case that what the particular request used.

Now it will instead always use the most recent host name to always use
the desired casing.

1- Two new error codes are introduced.

CURLE_FTP_ACCEPT_FAILED to be set whenever ACCEPTing fails because of

CURLE_FTP_ACCEPT_TIMEOUT to be set whenever ACCEPTing timeouts.

Neither of these errors are considered fatal and control connection
remains OK because it could just be a firewall blocking server to
connect to the client.

2- One new setopt option was introduced.

CURLOPT_ACCEPTTIMEOUT_MS

It sets the maximum amount of time FTP client is going to wait for a
server to connect. Internal default accept timeout is 60 seconds.
