... as the struct is free()d in the end anyway. It was first pointed out
to me that one of the ->msglist assignments were supposed to have been
->pending but was a copy and paste mistake when I realized none of the
clearing of pointers had to be there.
... instead of scanning through all handles, stash only the actual
handles that are in that state in the new ->pending list and scan that
list only. It should be mostly empty or very short. And only used for
pipelining.
This avoids a rather hefty slow-down especially notable if you add many
handles to the same multi handle. Regression introduced in commit
0f147887 (version 7.30.0).

SecCertificateCreateWithData() returns a non-NULL SecCertificateRef even
if the buffer holds an invalid or corrupt certificate. Call
SecCertificateCopyPublicKey() to make sure cacert is a valid
certificate.
Introducing Curl_expire_latest(). To be used when we the code flow only
wants to get called at a later time that is "no later than X" so that
something can be checked (and another timeout be added).
The low-speed logic for example could easily be made to set very many
expire timeouts if it would be called faster or sooner than what it had
set its own timer and this goes for a few other timers too that aren't
explictiy checked for timer expiration in the code.
If there's no condition the code that says if(time-passed >= TIME), then
Curl_expire_latest() is preferred to Curl_expire().
If there exists such a condition, it is on the other hand important that
Curl_expire() is used and not the other.

While waiting for a host resolve, check if the host cache may have
gotten the name already (by someone else), for when the same name is
resolved by several simultanoues requests.
The resolver thread occasionally gets stuck in getaddrinfo() when the
DNS or anything else is crappy or slow, so when a host is found in the
DNS cache, leave the thread alone and let itself cleanup the mess.
If the --cacert option is used with a CA certificate bundle that
contains multiple CA certificates, iterate through it, adding each
certificate as a trusted root CA.
This is usually due to failed auth. There's no point in us keeping such
a connection alive since it shouldn't be re-used anyway.

This was done to make sure NTLM state that is bound to a connection
doesn't survive and gets used for the subsequent request - but
disconnects can also be done to for example make room in the connection
cache and thus that connection is not strictly related to the easy
handle's current operation.
The http authentication state is still kept in the easy handle since all
http auth _except_ NTLM is connection independent and thus survive over
multiple connections.

Problem: if CURLOPT_FORBID_REUSE is set, requests using NTLM failed
since NTLM requires multiple requests that re-use the same connection
for the authentication to work
Solution: Ignore the forbid reuse flag in case the NTLM authentication
handshake is in progress, according to the NTLM state flag.

Corrected a number of the error codes that can be returned from the
Curl_sasl_create_gssapi_security_message() function when things go
wrong.
It makes more sense to return CURLE_BAD_CONTENT_ENCODING when the
inbound security challenge can't be decoded correctly or doesn't
contain the KERB_WRAP_NO_ENCRYPT flag and CURLE_OUT_OF_MEMORY when
EncryptMessage() fails. Unfortunately the previous error code of
CURLE_RECV_ERROR was a copy and paste mistakes on my part and should
have been correct in commit 4b491c675f :(
... to handle "*/[total]". Also, removed the strange hack that made
CURLOPT_FAILONERROR on a 416 response after a *RESUME_FROM return
CURLE_OK.

The new host doesn't support If-Modified-Since nor ETags, meaning that

Bringing back the old functionality that was mistakenly removed when the
connection cache was remade. When creating a new connection, all the
existing ones are checked and those that are known to be dead get
disconnected for real and removed from the connection cache. It helps
the cache from holding on to very many stale connections and aids in
keeping down the number of system sockets in wait states.

Curl_poll and Curl_wait_ms require the fix applied to Curl_socket_check
in commits b61e8b8 and c771968:
When poll or select are interrupted and coincides with the timeout
elapsing, the functions return -1 indicating an error instead of 0 for
the timeout.
Given the SSPI package info query indicates a token size of 4096 bytes,
updated to use a dynamic buffer for the response message generation
rather than a fixed buffer of 1024 bytes.
Updated to use a dynamic buffer for the SPN generation via the recently
introduced Curl_sasl_build_spn() function rather than a fixed buffer of
1024 characters, which should have been more than enough, but by using
the new function removes the need for another variable sname to do the
wide character conversion in Unicode builds.
Updated Curl_sasl_create_digest_md5_message() to use a dynamic buffer
for the SPN generation via the recently introduced Curl_sasl_build_spn()
function rather than a fixed buffer of 128 characters.
Curl_sasl_create_digest_md5_message() would simply cast the SPN variable
to a TCHAR when calling InitializeSecurityContext(). This meant that,
under Unicode builds, it would not be valid wide character string.
Updated to use the recently introduced Curl_sasl_build_spn() function
which performs the correct conversion for us.
Various parts of the libcurl source code build a SPN for inclusion in
authentication data. This information is either used by our own native
generation routines or passed to authentication functions in third-party
libraries such as SSPI. However, some of these instances use fixed
buffers rather than dynamically allocated ones and not all of those that
should, convert to wide character strings in Unicode builds.
Implemented a common function that generates a SPN and performs the
wide character conversion where necessary.
Following the recent changes and in attempt to align the SSPI based
authentication code performed the following:
* Use NULL and SECBUFFVERSION rather than hard coded constants.
* Avoid comparison of zero in if statements.
* Standardised the buf and desc setup code.
Given the SSPI package info query indicates a token size of 2888 bytes,
and as with the Winbind code and commit 9008f3d56, use a dynamic buffer
for the Type-1 and Type-3 message generation rather than a fixed buffer
of 1024 bytes.
Just as with the SSPI implementations of Digest and Negotiate added a
package info query so that libcurl can a) return a more appropriate
error code when the NTLM package is not supported and b) it can be of
use later to allocate a dynamic buffer for the Type-1 and Type-3
output tokens rather than use a fixed buffer of 1024 bytes.
OPENSSL_config() is "strongly recommended" to use but unfortunately that
function makes an exit() call on wrongly formatted config files which
makes it hard to use in some situations. OPENSSL_config() itself calls
CONF_modules_load_file() and we use that instead and we ignore its
return code!

If the server rejects our authentication attempt and curl hasn't
called CompleteAuthToken() then the status variable will be
SEC_I_CONTINUE_NEEDED and not SEC_E_OK.
As such the existing detection mechanism for determining whether or not
the authentication process has finished is not sufficient.
However, the WWW-Authenticate: Negotiate header line will not contain
any data when the server has exhausted the negotiation, so we can use
that coupled with the already allocated context pointer.
To prevent infinite loop in readwrite_data() function when stream is
reset before any response body comes, reset closed flag to false once
it is evaluated to true.
"Expect: 100-continue", which was once deprecated in HTTP/2, is now
resurrected in HTTP/2 draft 14. This change adds its support to
HTTP/2 code. This change also includes stricter header field
checking.
Previously it only returned a CURLcode for errors, which is when it
returns a different size than what was passed in to it.
The http2 code only checked the curlcode and thus failed.
Under these circumstances, the connection hasn't been fully established
and smtp_connect hasn't been called, yet smtp_done still calls the state
machine which dereferences the NULL conn pointer in struct pingpong.
This now provides a weak random function since PolarSSL doesn't have a
quick and easy way to provide a good one. It does however provide the
framework to make one so it _can_ and _should_ be done...
To force each backend implementation to really attempt to provide proper
random. If a proper random function is missing, then we can explicitly
make use of the default one we use when TLS support is missing.
This commit makes sure it works for darwinssl, gnutls, nss and openssl.
warning C4267: '=' : conversion from 'size_t' to 'long', possible loss
of data
The member connection_id of struct connectdata is a long (always a
32-bit signed integer on Visual C++) and the member next_connection_id
of struct conncache is a size_t, so one of them should be changed to
match the other.
This patch the size_t in struct conncache to long (the less invasive
change as that variable is only ever used in a single code line).

1 - fixes the warnings when built without http2 support
2 - adds CURLE_HTTP2, a new error code for errors detected by nghttp2
basically when they are about http2 specific things.
CyaSSL 3.0.0 returns a unique error code if no CA cert is available,
so translate that into CURLE_SSL_CACERT_BADFILE when peer verification
is requested.
