Automake gets confused if you want to use C++ static libraries with C
code - basically we need to involve the clang++ linker. The easiest way
of achieving this is to rename the C code as C++ code. This gets us a
bit further along the path and ought to be compatible with Google's
version of clang.
- Start with the basic code from the ossfuzz project.
- Rewrite fuzz corpora to be binary files full of Type-Length-Value
data, and write a glue layer in the fuzzing function to convert
corpora into CURL options.
- Have supporting functions to generate corpora from existing tests
- Integrate with Makefile.am
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.

Closes#1808
The required low-level logic was already available as part of
`libssh2` (via `LIBSSH2_FLAG_COMPRESS` `libssh2_session_flag()`[1]
option.)
This patch adds the new `libcurl` option `CURLOPT_SSH_COMPRESSION`
(boolean) and the new `curl` command-line option `--compressed-ssh`
to request this `libssh2` feature. To have compression enabled, it
is required that the SSH server supports a (zlib) compatible
compression method and that `libssh2` was built with `zlib` support
enabled.

Closes https://github.com/curl/curl/pull/1735
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`
now that the function only resets transfer sizes and no longer
modifies any of the progress timers.
- Add a bool to the `Progress` struct that is used to prevent
double-counting `t_starttransfer` times.
Added test case 1399.

The MSVC warning level defaults to 3 in CMake. Change it to 4, which is
consistent with the Visual Studio and NMake builds. Disable level 4
warning C4127 for the library and additionally C4306 for the test
servers to get a clean CURL_WERROR build as that warning is raised in
some macros in older Visual Studio versions.

MSVC warns that gethostbyname is deprecated. Always use getaddrinfo
instead to fix this when IPv6 is enabled, also for IPv4 resolves. This
is also consistent with what libcurl does.
Closes https://github.com/curl/curl/pull/1682
Older GCC warns:
/tests/server/rtspd.c:1194:10: warning: missing braces around
initializer [-Wmissing-braces]
Fix this by using memset instead of an initializer.
With warning level 4, MSVC warns about assignments within conditional
expressions. Change the while loop to a do-while loop to fix this. This
change is also consistent with CODE_STYLE.md.
This is a follow-up to af02162 which removed (SET_)ERRNO macros. That
commit was an earlier draft that I committed by mistake, which was then
remedied by a5834e5 and e909de6, and now this commit. With this commit
there is now no difference between the current code and the changes that
were approved in the final draft.

As per https://github.com/curl/curl/pull/1615, the DICT server is a
little spammy in torture mode due to the sockets being torn down
unexpectedly. Fix this by adding some error handling to the handling
function.
Closes#1629
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.
Closes#1616

The integer literal 3123123123 doesn't fit into a 32-bit signed
integer, so GCC with 32-bit long warns in C90 mode:
this decimal constant is unsigned only in ISO C90 [enabled by default]
Fix this by using ULONG_MAX, which should fit in any curl_off_t and has
the correct suffix to not issue any warnings.
Also adds the missing CURLOPT_REQUEST_TARGET from commit
9b167fd090.
Closes https://github.com/curl/curl/pull/1611

... 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.
Both these tests run the same underlying test code: libntlmconnect.c -
this test code made some assumptions about socket ordering when it used
curl_easy_fdset() and when we changed timing or got accidental changes
in libcurl the tests would fail.
The tests verify that the different transfers keep using the same
connections, which I now instead made sure by adding the number of bytes
each transfer gets and then verifies that they always get the same
amount as when these tests worked.
Closes#1576
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.
Closes#1543
Use CURLMcode for variable 'res' and cast to int where necessary
instead of the other way around. Other tests do the same.
This fixes the following clang warning:
lib583.c:68:15: warning: cast from function call of type 'CURLMcode' to
non-matching type 'int' [-Wbad-function-cast]
Also removed a TODO suggesting caching the precheck results. Tests
showed this would save about 0.1 sec on the total test run time on a
relatively modern system, an unnoticeable gain at the cost of longer and
more complicated code. There would also be a danger that a cached test
result would be inappropriately returned, such as when other test
dependencies (like environment variables) are different or when the
precheck causes side effects (like filesystem changes).
@MarcelRaad noted that `test1399` causes infinite loop on MinGW.
Looking into this, seems like it is related to how Windows handles
CRLF. See https://github.com/curl/curl/commit/9e093f by @mback2k.
Removing `test1399` as it's identical to `test1326` then with such a
fix.
Test 1399 was broughy by commit 862b02f894Closes#1478
Include the test number in the names of files written out by tests to

long is 32 bits while size_t is 64 bits on MinGW-w64, so
typecheck-gcc.h complains when using size_t for a long option.
Also, curl_socket_t is unsigned long long rather than int.
assign string literals to const char * instead of char * in order to
avoid a lot of these warnings:
cast from 'const char *' to 'char *' drops const qualifier

Windows does not allow setting the locale with environment variables (as
the test attempted to do), so the test failed when run with a user
locale that has a comma as radixchar. Changed the test to call
setlocale() explicitly to ensure that a known working locale is set even
on Windows.
Previous TODO wanting to write in chunks. We should support writing more
at once since some TELNET servers may respond immediately upon first

The 'list element' struct now has to be within the data that is being

Test 1300 updated accordingly.
