The comment here says that SecKeychainSearch causes a deprecation
warning when used with a minimum Mac OS X SDK version of 10.7.0, which
is correct. However, the #if guard did not match. It was intended to
only use the code if 10.6.0 support was enabled, but it had 10.7.0
instead. This caused a warning if the minimum was exactly 10.7.0.
The URI that is passed in as part of the Authorization: header needs to
be cut off at '?' if CURLAUTH_DIGEST_IE is set. Previously the code only
did when calculating the MD5sum.

POP3_TYPE_ANY, or ~0, is written to pop3c->preftype in lib/pop3c.c, an
unsigned int variable. The result of ~0 is -1, which caused a warning
due to writing a negative number to an unsigned variable. To fix this,
make the expression ~0U so that its value is considered the unsigned
number UINT_MAX which is what SASL_AUTH_ANY does in curl_sasl.h.
1) Renamed curl_tlsinfo to curl_tlssessioninfo as discussed on the
mailing list.
2) Renamed curl_ssl_backend to curl_sslbackend so it doesn't follow our
function naming convention.
3) Updated sessioninfo.c example accordingly.
This fixes a NULL dereference in the case where the client asks for
CURLINFO_TLS_SESSION data after the (TLS) session has already been
destroyed (i.e. curl_easy_perform has already completed for this
handle). Instead of crashing, we now return a CURLSSLBACKEND_NONE
error.
This is an extension to the fix in 7d80ed64e4. We may
call Curl_disconnect() while cleaning up the multi handle,
which could lead to openssl sending packets, which could get
a SIGPIPE.

Commit 7d80ed64e4 introduced some helpers to handle
sigpipe in easy.c. However, that fix was incomplete, and we
need to add more callers in other files. The first step is
making the helpers globally accessible.
Since the functions are small and should generally end up
inlined anyway, we simply define them in the header as
static functions.

This fixes a rare Happy Eyeballs bug where if the first IP family runs
out of addresses before the second-family-timer fires, and the second
IP family's first connect fails immediately, no further IPs of the
second family are attempted.
When adding entries to the DNS cache with CURLOPT_RESOLVE, they are
marked 'inuse' forever to prevent them from ever being removed in normal

Added new API for returning a SSL backend type and pointer, in order to
allow access to the TLS internals, that may then be used to obtain X509
certificate information for example.
Otherwise a NOOP operation would be performed which a) only returns a
single line response and not a multiline response where -I needs to be
used, and b) provides an inconsistent user experience compared to that
of the POP3 and IMAP protocols.
singleipconnect() could return the file descriptor of an open socket
even though the function returned a CURLE_COULDNT_CONNECT error code
from commit ed1662c374 and 02fbc26d59.
This could cause tests 19, 704 and 1233 to fail on FreeBSD, AIX and
Solaris.
Incorrectly processed multiline server greeting responses as "wanted"
continue responses in smtp_endofresp(), from commit f16c0de4e9,
which in turn broke the SMTP server detection in the test suite,
because the EHLO command would not be sent.
Added a loop to smtp_statemach_act() in which Curl_pp_readresp() is
called until the cache is drained. Without this multiple responses
received in a single packet could result in a hang or delay.
Similar to the processing of untagged CAPABILITY responses in IMAP moved
the processing of multiline EHLO responses to smtp_state_ehlo_resp() and
introduced an internal response code of one to differentiate a multiline
continuation from the end of command. This also allows for the separate
processing of multiline responses from commands such as VRFY and EXPN.
singleipconnect() did not return the open socket descriptor on some
errors, thereby sometimes causing a socket leak. This patch ensures
the socket is always returned.
Even though this is only a formality (since not many people build on
Mavericks while targeting Leopard), since we still support Leopard
at the earliest, we might as well be pedantic.
It turns out that some of the constants necessary to make this feature
work are missing from Snow Leopard's Security framework even though
they are defined in the headers.

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.
Should a client application fail to decode an authentication message
received from a server, or not support any of the parameters given by
the server in the message, then the authentication phrase should be
cancelled gracefully by the client rather than simply terminating the
connection.
The authentication phrase should be cancelled by simply sending a '*'
to the server, in response to erroneous data being received, as per
RFC-3501, RFC-4954 and RFC-5034.
This patch adds the necessary state machine constants and appropriate
response handlers in order to add this functionality for the CRAM-MD5,
DIGEST-MD5 and NTLM authentication mechanisms.
This is a regression since the switch to always-multi internally
c43127414d.
Test 1316 was modified since we now clearly call the Curl_client_write()
function when doing the LIST transfer part and then the
handler->protocol says FTP and ftpc.transfertype is 'A' which implies
text converting even though that the response is initially a HTTP
CONNECT response in this case.
This workaround had been previously been implemented for IMAP and POP3
but not SMTP. Some of the recent test case additions implemented this
behaviour to emulate a bad server and the SMTP code didn't cope with it.

Commit ad34a2d5c8 relies on definitions that are only present in
OpenSSL v1.0.1 and up. This quick fix allows the builds that use

According to the documentation for libssh2_userauth_list(), a NULL
return value is not necessarily an error. You must call
libssh2_userauth_authenticated() to determine if the SSH_USERAUTH_NONE

This fixes a segv when using sftp on a server that allows logins with an
empty password. When NULL was interpreted as an error, it would
free the session but not flag an error since the libssh2 errno would be
clear. This resulted in dereferencing a NULL session pointer.

I build curl.exe (using MingW) with '-DCURLDEBUG' and by importing from
libcurl.dll. Which means the new curl_easy_perform_ev() must be
exported from libcurl.dll.
Doing curl_multi_add_handle() on an easy handle that is already added to
a multi handle now returns this error code. It previously returned
CURLM_BAD_EASY_HANDLE for this condition.
The closure_handle is "owned" by the multi handle and it is
unconditional so the setting up of it should be in the Curl_multi_handle
function rather than curl_multi_add_handle.
This function is meant to work *exactly* as curl_easy_perform() but will
use the event-based libcurl API internally instead of
curl_multi_perform(). To avoid relying on an actual event-based library
and to not use non-portable functions (like epoll or similar), there's a
rather inefficient emulation layer implemented on top of Curl_poll()
instead.
There's currently some convenience logging done in curl_easy_perform_ev
which helps when tracking down problems. They may be suitable to remove
or change once things seem to be fine enough.
curl has a new --test-event option when built with debug enabled that
then uses curl_easy_perform_ev() instead of curl_easy_perform(). If
built without debug, using --test-event will only output a warning
message.
NOTE: curl_easy_perform_ev() is not part if the public API on purpose.
It is only present in debug builds of libcurl and MUST NOT be considered
stable even then. Use it for libcurl-testing purposes only.
runtests.pl now features an -e command line option that makes it use
--test-event for all curl command line tests. The man page is updated.
libcurl quietly truncates usernames, passwords, and options from

support longer passwords.
After this change, there are no more uses of MAX_CURL_OPTIONS_LENGTH

username and password length constants, on the other hand, are still

Instead of nesting "if(success)" blocks and leaving the reader in

No functional change intended. The main effect is to decrease the
indentation of this function slightly.
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

libcurl truncates usernames and passwords it reads from .netrc to
LOGINSIZE and PASSWORDSIZE (64) characters without any indication to

Fix the interface by passing back dynamically allocated buffers
allocated to fit the user's input. The parser still relies on a

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

With everything being struct SessionHandle pointers now, this rename
makes multi.c use the library-wide practise of calling that pointer
'data' instead of the previously used 'easy'.
Moved Curl_easy_addmulti() from easy.c to multi.c, renamed it to
easy_addmulti and made it static.
Removed Curl_easy_initHandleData() and uses of it since it was emptied
in commit cdda92ab67b47d74a.
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.
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.
CURLOPT_DNS_USE_GLOBAL_CACHE broke in commit c43127414d (been

documented as deprecated for almost a decade and nobody even reported
this bug, it should remain functional.
Added test case 1512 to verify
The previous naming scheme ftp_state_post_XXXX() wasn't really helpful
as it wasn't always immediately after 'xxxx' and it wasn't easy to
understand what it does based on such a name.
This new one is instead ftp_state_yyyy() where yyyy describes what it
does or sends.
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...

For some reason, OS X 10.5's GCC suddenly stopped working correctly with
macros that change MD5_Init etc. in the code to CC_MD5_Init etc., so I
worked around this by removing use of the macros and inserting static
functions that just call CommonCrypto's implementations of the functions
instead.
This changes the previous check for untrusted certs to a check for
certs explicitely marked as trusted.
The change is backward-compatible (tested with certdata.txt v1.80).
The internal function that's used to detect known file extensions for
the default Content-Type got the the wrong pointer passed in when
CURLFORM_BUFFER + CURLFORM_BUFFERPTR were used. This had the effect that
strlen() would be used which could lead to an out-of-bounds read (and
thus segfault). In most cases it would only lead to it not finding or
using the correct default content-type.
It also showed that test 554 and test 587 were testing for the
previous/wrong behavior and now they're updated as well.

Christian Heimes brought to our attention that the certdata.txt
format has recently changed [1], causing ca-bundle.crt created
with mk-ca-bundle.[pl|vbs] to include untrusted certs.

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
(This doesn't need to appear in the release notes.) I noticed a few places
where infof() was called, and there should've been an LF at the end of the
string, but there wasn't.
It turns out Snow Leopard not only has SecItemCopyMatching() defined in
a header not included by the omnibus header, but it won't work for our
purposes, because searching for SecIdentityRef objects wasn't added
to that API until Lion. So we now use the old SecKeychainSearch API
instead if the user is building under, or running under, Snow Leopard.

Previously we used __MAC_10_X and __IPHONE_X to mark digest-generating
code that was specific to OS X and iOS. Now we use
__MAC_OS_X_VERSION_MAX_ALLOWED and __IPHONE_OS_VERSION_MAX_ALLOWED
instead of those macros.

For the standard VMS text file formats, VMS needs to read the file to
get the actual file size.
For the standard VMS binary file formats, VMS needs a special format of
fopen() call so that it stops reading at the logical end of file instead
of at the end of the blocks allocated to the file.
I structured the patch this way as I was not sure about changing the
structures or parameters to the routines, but would prefer to only call
the stat() function once and pass the information to where the fopen()
call is made.

The code for CURLFORM_FILECONTENT had its check for duplicate options
wrong so that it would reject CURLFORM_PTRNAME if used in combination
with it (but not CURLFORM_COPYNAME)! The flags field used for this
purpose cannot be interpreted that broadly.

Commit 6d30f8ebed didn't work properly. First, it used the wrong
array index, but this fix also:
1 - only does the copying if indeed there was any activity
2 - makes sure to properly translate between internal and external
bitfields, which are not guaranteed to match

Instead of going 50,100,150 etc millisecond delay time when nothing has
been found to do or wait for, we now start lower and double each loop as
in 4,8,16,32 etc.
This lowers the minimum wait without sacrifizing the longer wait too
much with unnecessary CPU cycles burnt.

In the case of an active connection when ftp_do_more() detects that the
server has connected back, it must make sure to mark it as complete so
that the multi_runsingle() function will detect this and move on to the
next state.

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.
This reverts commit 7ed25cc, reinstating commit 8ec2cb5.
As of 18-jul-2013 we still do have code in libcurl that makes use of these
memory functions. Commit 8ec2cb5 comment still applies and is yet valid.
These memory functions are solely used in Windows builds, so all related
code is protected with '#ifdef WIN32' preprocessor conditional compilation
directives.
Specifically, wcsdup() _wcsdup() are used when building a Windows target with
UNICODE and USE_WINDOWS_SSPI preprocessor symbols defined. This is the case
when building a Windows UNICODE target with Windows native SSL/TLS support
enabled.
Realizing that wcsdup() _wcsdup() are used is a bit tricky given that usage
of these is hidden behind _tcsdup() which is MS way of dealing with code
that must tolerate UNICODE and non-UNICODE compilation. Additionally, MS
header files and those compatible from other compilers use this preprocessor
conditional compilation directive in order to select at compilation time
whether 'wide' or 'ansi' MS API functions are used.
Without this code, Windows build targets with Windows native SSL/TLS support
enabled and MemoryTracking support enabled misbehave in tracking memory usage,
regardless of being a UNICODE enabled build or not.
Fixed issue with static build for MSVC2010.
After some investigation I've discovered known issue
http://public.kitware.com/Bug/view.php?id=11240 When .rc file is linked
to static lib it fails with following linker error
LINK : warning LNK4068: /MACHINE not specified; defaulting to X86
file.obj : fatal error LNK1112: module machine type 'x64' conflicts with
target machine type 'X86'
Fix add target property /MACHINE: for MSVC generation.
Also removed old workarounds - it caused errors during msvc build.
