c6aedf680f fread_func: move callback pointer from set to state struct
... and assign it from the set.fread_func_set pointer in the
Curl_init_CONNECT function. This A) avoids that we have code that
assigns fields in the 'set' struct (which we always knew was bad) and
more importantly B) it makes it impossibly to accidentally leave the
wrong value for when the handle is re-used etc.

Introducing a state-init functionality in multi.c, so that we can set a
specific function to get called when we enter a state. The
Curl_init_CONNECT is thus called when switching to the CONNECT state.

Bug: https://github.com/bagder/curl/issues/346

Closes #346

9756d1da76 CURLOPT_DEFAULT_PROTOCOL: added
- Add new option CURLOPT_DEFAULT_PROTOCOL to allow specifying a default
protocol for schemeless URLs.

- Add new tool option --proto-default to expose
CURLOPT_DEFAULT_PROTOCOL.

In the case of schemeless URLs libcurl will behave in this way:

When the option is used libcurl will use the supplied default.

When the option is not used, libcurl will follow its usual plan of
guessing from the hostname and falling back to 'http'.

c5d060cab4 HTTP: ignore "Content-Encoding: compress"
Currently, libcurl rejects responses with "Content-Encoding: compress"
when CURLOPT_ACCEPT_ENCODING is set to "". I think that libcurl should
treat the Content-Encoding "compress" the same as other
Content-Encodings that it does not support, e.g. "bzip2". That means
just ignoring it.

172b2beba6 SSL: Add an option to disable certificate revocation checks
New tool option --ssl-no-revoke.
New value CURLSSLOPT_NO_REVOKE for CURLOPT_SSL_OPTIONS.

Currently this option applies only to WinSSL where we have automatic
certificate revocation checking by default. According to the
ssl-compared chart there are other backends that have automatic checking
(NSS, wolfSSL and DarwinSSL) so we could possibly accommodate them at
some later point.

3e7ec1e849 schannel: schannel_recv overhaul
This commit is several drafts squashed together. The changes from each
draft are noted below. If any changes are similar and possibly
contradictory the change in the latest draft takes precedence.

Bug: https://github.com/bagder/curl/issues/244
Reported-by: Chris Araman

%%
%% Draft 1
%%
- return 0 if len == 0. that will have to be documented.
- continue on and process the caches regardless of raw recv
- if decrypted data will be returned then set the error code to CURLE_OK
and return its count
- if decrypted data will not be returned and the connection has closed
(eg nread == 0) then return 0 and CURLE_OK
- if decrypted data will not be returned and the connection *hasn't*
closed then set the error code to CURLE_AGAIN --only if an error code
isn't already set-- and return -1
- narrow the Win2k workaround to only Win2k

%%
%% Draft 2
%%
- Trying out a change in flow to handle corner cases.

%%
%% Draft 3
%%
- Back out the lazier decryption change made in draft2.

%%
%% Draft 4
%%
- Some formatting and branching changes
- Decrypt all encrypted cached data when len == 0
- Save connection closed state
- Change special Win2k check to use connection closed state

%%
%% Draft 5
%%
- Default to CURLE_AGAIN in cleanup if an error code wasn't set and the
connection isn't closed.

%%
%% Draft 6
%%
- Save the last error only if it is an unrecoverable error.

Prior to this I saved the last error state in all cases; unfortunately
the logic to cover that in all cases would lead to some muddle and I'm
concerned that could then lead to a bug in the future so I've replaced
it by only recording an unrecoverable error and that state will persist.

- Do not recurse on renegotiation.

Instead we'll continue on to process any trailing encrypted data
received during the renegotiation only.

- Move the err checks in cleanup after the check for decrypted data.

In either case decrypted data is always returned but I think it's easier
to understand when those err checks come after the decrypted data check.

%%
%% Draft 7
%%
- Regardless of len value go directly to cleanup if there is an
unrecoverable error or a close_notify was already received. Prior to
this change we only acknowledged those two states if len != 0.

- Fix a bug in connection closed behavior: Set the error state in the
cleanup, because we don't know for sure it's an error until that time.

- (Related to above) In the case the connection is closed go "greedy"
with the decryption to make sure all remaining encrypted data has been
decrypted even if it is not needed at that time by the caller. This is
necessary because we can only tell if the connection closed gracefully
(close_notify) once all encrypted data has been decrypted.

- Do not renegotiate when an unrecoverable error is pending.

%%
%% Draft 8
%%
- Don't show 'server closed the connection' info message twice.

- Show an info message if server closed abruptly (missing close_notify).

9081014c2c IPV6: address scope != scope id
There was a confusion between these: this commit tries to disambiguate them.
- Scope can be computed from the address itself.
- Scope id is scope dependent: it is currently defined as 1-based local
  interface index for link-local scoped addresses, and as a site index(?) for
  (obsolete) site-local addresses. Linux only supports it for link-local
  addresses.
The URL parser properly parses a scope id as an interface index, but stores it
in a field named "scope": confusion. The field has been renamed into "scope_id".
Curl_if2ip() used the scope id as it was a scope. This caused failures
to bind to an interface.
Scope is now computed from the addresses and Curl_if2ip() matches them.
If redundantly specified in the URL, scope id is check for mismatch with
the interface index.

This commit should fix SF bug #1451.

970c22f970 libcurl: add UNIX domain sockets support
The ability to do HTTP requests over a UNIX domain socket has been
requested before, in Apr 2008 [0][1] and Sep 2010 [2]. While a
discussion happened, no patch seems to get through. I decided to give it
a go since I need to test a nginx HTTP server which listens on a UNIX
domain socket.

One patch [3] seems to make it possible to use the
CURLOPT_OPENSOCKETFUNCTION function to gain a UNIX domain socket.
Another person wrote a Go program which can do HTTP over a UNIX socket
for Docker[4] which uses a special URL scheme (though the name contains
cURL, it has no relation to the cURL library).

This patch considers support for UNIX domain sockets at the same level
as HTTP proxies / IPv6, it acts as an intermediate socket provider and
not as a separate protocol. Since this feature affects network
operations, a new feature flag was added ("unix-sockets") with a
corresponding CURL_VERSION_UNIX_SOCKETS macro.

A new CURLOPT_UNIX_SOCKET_PATH option is added and documented. This
option enables UNIX domain sockets support for all requests on the
handle (replacing IP sockets and skipping proxies).

A new configure option (--enable-unix-sockets) and CMake option
(ENABLE_UNIX_SOCKETS) can disable this optional feature. Note that I
deliberately did not mark this feature as advanced, this is a
feature/component that should easily be available.

When duplicating a handle, the data to post was duplicated using

tool with this change, it now uses its own version instead.

84bd19ffd4 timers: fix timer regression involving redirects / reconnects
In commit 0b3750b5c2 (released in 7.36.0) we fixed a timeout issue
but instead broke the timings.

To fix this, I introduce a new timestamp to use for the timeouts and
restored the previous timestamp and timestamp position so that the old
timer functionality is restored.

In addition to that, that change also broke connection timeouts for when
more than one connect was used (as it would then count the total time
from the first connect and not for the most recent one). Now
Curl_timeleft() has been modified so that it checks against different
start times depending on which timeout it checks.

Test 1303 is updated accordingly.

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.

credentials are specified. Fixed the detection logic to include these
other protocols.

Rename x509_cert to x509_crt and add "compat-1.2.h"

This would still need some more thorough conversion

219a0fbe76 remote_port: allow connect to port 0
Port number zero is perfectly allowed to connect to. I moved to storing
the remote port number in an int so that -1 means undefined and 0-65535
can be used for legitimate port numbers.

22c198fa89 openssl: set up hooks with to perform NPN
NPN is what is available in the wild today to negotiate SPDY or HTTP/2.0
connections. It is expected to be replaced by ALPN in the future. If
HTTP/2.0 is negotiated, this is indicated for the entire connection and
http.c is expected to initialize itself for HTTP/2.0 instead of
HTTP/1.1.

dc68120e63 curl_easy_getinfo: Post CURLINFO_TLS_SESSION tidy up
1) Renamed curl_tlsinfo to curl_tlssessioninfo as discussed on the

2) Renamed curl_ssl_backend to curl_sslbackend so it doesn't follow our
function naming convention.
3) Updated sessioninfo.c example accordingly.

7d7df83198 Add "Happy Eyeballs" for IPv4/IPv6.
This patch invokes two socket connect()s nearly simultaneously, and
the socket that is first connected "wins" and is subsequently used for
the connection. The other is terminated.

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

bb55293313 FTP: remove krb4 support
We've announced this pending removal for a long time and we've
repeatedly asked if anyone would care or if anyone objects. Nobody has
objected. It has probably not even been working for a good while since
nobody has tested/used this code recently.

The stuff in krb4.h that was generic enough to be used by other sources
is now present in security.h

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).

e79535bc5e SessionHandle: the protocol specific pointer is now a void *
All protocol handler structs are now opaque (void *) in the
SessionHandle struct and moved in the request-specific sub-struct
'SingleRequest'. The intension is to keep the protocol specific
knowledge in their own dedicated source files [protocol].c etc.

There's some "leakage" where this policy is violated, to be addressed at
a later point in time.

4ad8e142da urldata: clean up the use of the protocol specific structs
1 - always allocate the struct in protocol->setup_connection. Some
protocol handlers had to get this function added.

2 - always free at the end of a request. This is also an attempt to keep
less memory in the handle after it is completed.

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...

09b9fc9009 multi: remove 'Curl_one_easy' struct, phase 1
The motivation for having a separate struct that keep track of an easy
handle when using the multi handle was removed when we switched to
always using the multi interface internally. Now they were just two
separate struct that was always allocated for each easy handle.

This first step just moves the Curl_one_easy struct members into the
SessionHandle struct and hides this somehow (== keeps the source code
changes to a minimum) by defining Curl_one_easy to SessionHandle

The biggest changes in this commit are:

 1 - the linked list of easy handles had to be changed somewhat due
     to the new struct layout. This made the main linked list pointer
     get renamed to 'easyp' and there's also a new pointer to the last
     node, called easylp. It is no longer circular but ends with ->next
     pointing to NULL. New nodes are still added last.

 2 - easy->state is now called easy->mstate to avoid name collision

12d01cb6fa CURLOPT_XFERINFOFUNCTION: introducing a new progress callback
CURLOPT_XFERINFOFUNCTION is now the preferred progress callback function
and CURLOPT_PROGRESSFUNCTION is considered deprecated.

This new callback uses pure 'curl_off_t' arguments to pass on full
resolution sizes. It otherwise retains the same characteristics: the
same call rate, the same meanings for the arguments and the return code
is used the same way.

The progressfunc.c example is updated to show how to use the new
callback for newer libcurls while supporting the older one if built with
an older libcurl or even built with a newer libcurl while running with
an older.
