To support telling a string is nul-terminated, symbol CURL_ZERO_TERMINATED
has been introduced.
Documentation updated accordingly.
symbols in versions updated. Added form API symbols deprecation info.
This feature is badly supported in Windows: as a replacement, a caller has
to use curl_mime_data_cb() with fread, fseek and possibly fclose
callbacks to process opened files.
The cli tool and documentation are updated accordingly.
The feature is however kept internally for form API compatibility, with
the known caveats it always had.
As a side effect, stdin size is not determined by the cli tool even if
possible and this results in a chunked transfer encoding. Test 173 is
updated accordingly.
Some calls in different modules were setting the data handle to NULL, causing
segmentation faults when using builds that enable character code conversions.
destroy_async_data() assumes that if the flag "done" is not set yet, the
thread itself will clean up once the request is complete. But if an
error (generally OOM) occurs before the thread even has a chance to
start, it will never get a chance to clean up and memory will be leaked.
By clearing "done" only just before starting the thread, the correct
cleanup sequence will happen in all cases.
Previously, we used as default SSL backend whatever was first in the
`available_backends` array.
However, some users may want to override that default without patching
the source code.
Now they can: with the --with-default-ssl-backend=<backend> option of
the ./configure script.

When only one SSL backend is configured, it is totally unnecessary to
let multissl_init() configure the backend at runtime, we can select the
correct backend at build time already.
Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
Let's add a compile time safe API to select an SSL backend. This
function needs to be called *before* curl_global_init(), and can be
called only once.
Side note: we do not explicitly test that it is called before
curl_global_init(), but we do verify that it is not called multiple times
(even implicitly).
If SSL is used before the function was called, it will use whatever the
CURL_SSL_BACKEND environment variable says (or default to the first
available SSL backend), and if a subsequent call to
curl_global_sslset() disagrees with the previous choice, it will fail
with CURLSSLSET_TOO_LATE.
The function also accepts an "avail" parameter to point to a (read-only)
NULL-terminated list of available backends. This comes in real handy if
an application wants to let the user choose between whatever SSL backends
the currently available libcurl has to offer: simply call
curl_global_sslset(-1, NULL, &avail);
which will return CURLSSLSET_UNKNOWN_BACKEND and populate the avail
variable to point to the relevant information to present to the user.
Just like with the HTTP/2 push functions, we have to add the function
declaration of curl_global_sslset() function to the header file
*multi.h* because VMS and OS/400 require a stable order of functions
declared in include/curl/*.h (where the header files are sorted
alphabetically). This looks a bit funny, but it cannot be helped.

There is information about the compiled-in SSL backends that is really
no concern of any code other than the SSL backend itself, such as which
function (if any) implements SHA-256 summing.
And there is information that is really interesting to the user, such as
the name, or the curl_sslbackend value.
Let's factor out the latter into a publicly visible struct. This
information will be used in the upcoming API to set the SSL backend
globally.
Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
When building software for the masses, it is sometimes not possible to
decide for all users which SSL backend is appropriate.
Git for Windows, for example, uses cURL to perform clones, fetches and
pushes via HTTPS, and some users strongly prefer OpenSSL, while other
users really need to use Secure Channel because it offers
enterprise-ready tools to manage credentials via Windows' Credential
Store.
The current Git for Windows versions use the ugly work-around of
building libcurl once with OpenSSL support and once with Secure Channel
support, and switching out the binaries in the installer depending on
the user's choice.
Needless to say, this is a super ugly workaround that actually only
works in some cases: Git for Windows also comes in a portable form, and
in a form intended for third-party applications requiring Git
functionality, in which cases this "swap out libcurl-4.dll" simply is
not an option.
Therefore, the Git for Windows project has a vested interest in teaching
cURL to make the SSL backend a *runtime* option.
This patch makes that possible.
By running ./configure with multiple --with-<backend> options, cURL will
be built with multiple backends.
For the moment, the backend can be configured using the environment
variable CURL_SSL_BACKEND (valid values are e.g. "openssl" and
"schannel").
Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
So far, all of the SSL backends' private data has been declared as
part of the ssl_connect_data struct, in one big #if .. #elif .. #endif
block.
This can only work as long as the SSL backend is a compile-time option,
something we want to change in the next commits.
Therefore, let's encapsulate the exact data needed by each SSL backend
into a private struct, and let's avoid bleeding any SSL backend-specific
information into urldata.h. This is also necessary to allow multiple SSL
backends to be compiled in at the same time, as e.g. OpenSSL's and
CyaSSL's headers cannot be included in the same .c file.
To avoid too many malloc() calls, we simply append the private structs
to the connectdata struct in allocate_conn().
This requires us to take extra care of alignment issues: struct fields
often need to be aligned on certain boundaries e.g. 32-bit values need to
be stored at addresses that divide evenly by 4 (= 32 bit / 8
bit-per-byte).
We do that by assuming that no SSL backend's private data contains any
fields that need to be aligned on boundaries larger than `long long`
(typically 64-bit) would need. Under this assumption, we simply add a
dummy field of type `long long` to the `struct connectdata` struct. This
field will never be accessed but acts as a placeholder for the four
instances of ssl_backend_data instead. the size of each ssl_backend_data
struct is stored in the SSL backend-specific metadata, to allow
allocate_conn() to know how much extra space to allocate, and how to
initialize the ssl[sockindex]->backend and proxy_ssl[sockindex]->backend
pointers.
This would appear to be a little complicated at first, but is really
necessary to encapsulate the private data of each SSL backend correctly.
And we need to encapsulate thusly if we ever want to allow selecting
CyaSSL and OpenSSL at runtime, as their headers cannot be included within
the same .c file (there are just too many conflicting definitions and
declarations for that).

At the moment, cURL's SSL backend needs to be configured at build time.
As such, it is totally okay for them to hard-code their backend-specific
data in the ssl_connect_data struct.
In preparation for making the SSL backend a runtime option, let's make
the access of said private data a bit more abstract so that it can be
adjusted later in an easy manner.

In 86b889485 (sasl_gssapi: Added GSS-API based Kerberos V5 variables,
2014-12-03), an SSPI-specific field was added to the kerberos5data
struct without moving the #include "curl_sspi.h" later in the same file.
This broke the build when SSPI was enabled, unless Secure Channel was
used as SSL backend, because it just so happens that Secure Channel also
requires "curl_sspi.h" to be #included.
In f4739f639 (urldata: include curl_sspi.h when Windows SSPI is enabled,
2017-02-21), this bug was fixed incorrectly: Instead of moving the
appropriate conditional #include, the Secure Channel-conditional part
was now also SSPI-conditional.
Fix this problem by moving the correct #include instead.
This is also required for an upcoming patch that moves all the Secure
Channel-specific stuff out of urldata.h and encapsulates it properly in
vtls/schannel.c instead.

2. It finally weak-links the connectx() function, and falls back on
connect() when run on older operating systems.
Update the progress timers `t_nslookup`, `t_connect`, `t_appconnect`,
`t_pretransfer`, and `t_starttransfer` to track the total times for
these activities when a redirect is followed. Previously, only the times
for the most recent request would be tracked.
Related changes:
- Rename `Curl_pgrsResetTimesSizes` to `Curl_pgrsResetTransferSizes`

modifies any of the progress timers.
- Add a bool to the `Progress` struct that is used to prevent
double-counting `t_starttransfer` times.

There are some bugs in how timers are managed for a single easy handle
that causes the wrong "next timeout" value to be reported to the
application when a new minimum needs to be recomputed and that new
minimum should be an existing timer that isn't currently set for the
easy handle. When the application drives a set of easy handles via the
`curl_multi_socket_action()` API (for example), it gets told to wait the
wrong amount of time before the next call, which causes requests to
linger for a long time (or, it is my guess, possibly forever).

- Change gnutls pointer/int macros to pointer/curl_socket_t.
Prior to this change they used long type as well.
The size of the `long` data type can be shorter than that of pointer
types. This is the case most notably on Windows.
If C99 were acceptable, we could simply use `intptr_t` here. But we
want to retain C89 compatibility.
Simply use the trick of performing pointer arithmetic with the NULL
pointer: to convert an integer `i` to a pointer, simply take the
address of the `i`th element of a hypothetical character array
starting at address NULL. To convert back, simply cast the pointer
difference.
Thanks to Jay Satiro for the initial modification to use curl_socket_t
instead of int/long.

Add a new type of callback to Curl_handler which performs checks on
the connection. Alter RTSP so that it uses this callback to do its
own check on connection health.
Prevent `Curl_pgrsTime` from modifying `t_starttransfer` when invoked
with `TIMER_STARTTRANSFER` more than once during a single request.
When a redirect occurs, this is considered a new request and
`t_starttransfer` can be updated to reflect the `t_starttransfer` time
of the redirect request.

Bug: https://github.com/curl/curl/pull/1602#issuecomment-310267370
If libcurl was built with GSS-API support, it unconditionally advertised
GSS-API authentication while connecting to a SOCKS5 proxy. This caused
problems in environments with improperly configured Kerberos: a stock
libcurl failed to connect, despite libcurl built without GSS-API
connected fine using username and password.
This commit introduces the CURLOPT_SOCKS5_AUTH option to control the
allowed methods for SOCKS5 authentication at run time.
Note that a new option was preferred over reusing CURLOPT_PROXYAUTH
for compatibility reasons because the set of authentication methods
allowed by default was different for HTTP and SOCKS5 proxies.

This change introduces new alternatives for the existing six
curl_easy_getinfo() options that return sizes or speeds as doubles. The
new versions are named like the old ones but with an appended '_T':
CURLINFO_CONTENT_LENGTH_DOWNLOAD_T
CURLINFO_CONTENT_LENGTH_UPLOAD_T
CURLINFO_SIZE_DOWNLOAD_T
CURLINFO_SIZE_UPLOAD_T
CURLINFO_SPEED_DOWNLOAD_T
CURLINFO_SPEED_UPLOAD_T

... the previous code would reset the header length wrongly (since
5113ad0424). This makes test 1060 reliable again.
Also: make sws send even smaller chunks of data to increase the
likeliness of this happening.
- No longer allow partial downloads of certdata.
Prior to this change partial downloads were (erroneously?) allowed since
only the server code was checked to be 200.

When this define was set, libcurl would check the environment variable
named CURL_CA_BUNDLE at run-time and use that CA cert bundle. This
feature was only defined by the watcom and m32 makefiles and caused
inconsistent behaviours among libcurls built on different platforms.
The curl tool does already feature its own similar logic and the library
does not really need it, and it isn't documented libcurl behavior. So
this change removes it.

This gives us accurate precision and it allows us to avoid storing "no
time" for systems with too low timer resolution as we then bump the time
up to 1 microsecond. Should fix test 573 on windows.
Remove the now unused curlx_tvdiff_secs() function.
Maintains the external getinfo() API with using doubles.
Fixes#1531
With the introduction of expire IDs and the fact that existing timers
can be removed now and thus never expire, the concept with adding a
"latest" timer is not working anymore as it risks to not expire at all.
So, to be certain the timers actually are in line and will expire, the
plain Curl_expire() needs to be used. The _latest() function was added
as a sort of shortcut in the past that's quite simply not necessary
anymore.

mk-lib1521.pl generates a test program (lib1521.c) that calls
curl_easy_setopt() for every known option with a few typical values to
make sure they work (ignoring the return codes).
Some small changes were necessary to avoid asserts and NULL accesses
when doing this.
The perl script needs to be manually rerun when we add new options.

This fixes the following warning with CURL_DISABLE_CRYPTO_AUTH,
as seen in the autobuilds:
curl_sasl.c:417:9: warning: unused variable 'serverdata'
[-Wunused-variable]
cyassl/ssl.h needs the macros from cyassl/options.h, so define them
before including cyassl/ssl.h the first time, which happens in
urldata.h.
This broke the build on Ubuntu Xenial, which comes with WolfSSL 3.4.8
and therefore redefines the symbols from cyassl/options.h instead of
including the header.
Closes https://github.com/curl/curl/pull/1536

Bug: #1294
* LDAP: using ldap_bind_s on Windows with methods(BASIC/DIGEST/NTLM/AUTONEG)
* ldap: updated per build options handling
* ldap: fixed logic for auth selection
Fixed a syntax error with setting cache variables (The type and
docstring were missing), resulting in build errors. Quoted the
CURL_CA_PATH and CURL_CA_BUNDLE otherwise the path was written without
quotes in C code, resulting in build errors.

.... caused by a typo in the last commit (fixing issue #1504):
memdebug.c: In function ‘curl_fclose’:
memdebug.c:444:3: error: implicit declaration of function
‘DEBUGDEBUGASSERT’ [-Werror=implicit-function-declaration]
Some code (e.g. Curl_fillreadbuffer) assumes that this buffer is not
exceedingly tiny and will break if it is. This same check is already
done at run time in the CURLOPT_BUFFERSIZE option.
The function IsPipeliningPossible() would return TRUE if either
pipelining OR HTTP/2 were possible on a connection, which would lead to
it returning TRUE even for POSTs on HTTP/1 connections.
It now returns a bitmask so that the caller can differentiate which kind
the connection allows.
