CURLE_PEER_FAILED_VERIFICATION makes more sense because Curl_parseX509
does not allocate memory internally as its first argument is a pointer
to the certificate structure. The same error code is also returned by
Curl_verifyhost when its call to Curl_parseX509 fails so the change
makes error handling more consistent.
Transparently. The related curl_multi_setopt() options all still returns
OK when pipelining is selected.
To re-enable the support, the single line change in lib/multi.c needs to
be reverted.
See docs/DEPRECATE.md
Closes#2705
According to RFC6265 section 5.4, cookies with equal path lengths
SHOULD be sorted by creation-time (earlier first). This adds a
creation-time record to the cookie struct in order to make cookie
sorting more deterministic. The creation-time is defined as the
order of the cookies in the jar, the first cookie read fro the
jar being the oldest. The creation-time is thus not serialized
into the jar. Also remove the strcmp() matching in the sorting as
there is no lexicographic ordering in RFC6265. Existing tests are
updated to match.

As uintptr_t and HANDLE are always the same size, this warning is
harmless. Just silence it using an intermediate uintptr_t variable.

1) Using CERT_STORE_OPEN_EXISTING_FLAG ( or CERT_STORE_READONLY_FLAG )
while opening certificate store would be sufficient in this scenario and
less-demanding in sense of required user credentials ( for example,
IIS_IUSRS will get "Access Denied" 0x05 error for existing CertOpenStore
call without any of flags mentioned above ),
2) as 'cert_store_name' is a DWORD, attempt to format its value like a
string ( in "Failed to open cert store" error message ) will throw null
pointer exception
3) adding GetLastError(), in my opinion, will make error message more
useful.

Since GOPHER support was added in curl `?' character was automatically
translated to `%09' (`\t').
However, this behaviour does not seems documented in RFC 4266 and for
search selectors it is documented to directly use `%09' in the URL.
Apart that several gopher servers in the current gopherspace have CGI
support where `?' is used as part of the selector and translating it to
`%09' often leads to surprising results.

Handles created with curl_easy_duphandle do not use the SSL engine set

The verbose message "Authentication using SSH public key file" was
printed each time the ssh_userauth_publickey_auto() was called, which
meant each time a packet was transferred over network because the API
operates in non-blocking mode.
This patch makes sure that the verbose message is printed just once
(when the authentication state is entered by the SSH state machine).
Deal with tiny "HTTP/0.9" (header-less) responses by checking the
status-line early, even before a full "HTTP/" is received to allow
detecting 0.9 properly.

This allows the use of PKCS#11 URI for certificates and keys without
setting the corresponding type as "ENG" and the engine as "pkcs11"
explicitly. If a PKCS#11 URI is provided for certificate, key,
proxy_certificate or proxy_key, the corresponding type is set as "ENG"
if not provided and the engine is set to "pkcs11" if not provided.

So far, the code tries to pick an authentication method only if
user/password credentials are available, which is not the case for
Bearer authentictation...
Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
Closes#2754
The Bearer authentication was added to cURL 7.61.0, but there is a
problem: if CURLAUTH_ANY is selected, and the server supports multiple
authentication methods including the Bearer method, we strongly prefer
that latter method (only CURLAUTH_NEGOTIATE beats it), and if the Bearer
authentication fails, we will never even try to attempt any other
method.
This is particularly unfortunate when we already know that we do not
have any Bearer token to work with.
Such a scenario happens e.g. when using Git to push to Visual Studio
Team Services (which supports Basic and Bearer authentication among
other methods) and specifying the Personal Access Token directly in the
URL (this aproach is frequently taken by automated builds).
Let's make sure that we have a Bearer token to work with before we
select the Bearer authentication among the available authentication
methods.

It was previously erroneously skipped in some situations.
libtest/libntlmconnect.c wrongly depended on wrong behavior (that it

will always return a -1 timeout when all handles are completed.

Commit 38203f1585 changed engine detection to be version-based,
with a baseline of openssl 1.0.1. This does in fact break builds
with openssl 1.0.0, which has engine support - the configure script
detects that ENGINE_cleanup() is available - but <openssl/engine.h>
doesn't get included to declare it.
According to upstream documentation, engine support was added to
mainstream openssl builds as of version 0.9.7:
https://github.com/openssl/openssl/blob/master/README.ENGINE
This commit drops the version test down to 1.0.0 as version 1.0.0d
is the oldest version I have to test with.
