They're not thread-safe so they should not be used in libcurl code.

timeval::tv_usec might be a 32-bit integer and timespec::tv_nsec might
be a 64-bit integer. This is the case when building for recent macOS
versions, for example. Just treat tv_usec as an int, which should
hopefully always be sufficient on systems with
`HAVE_CLOCK_GETTIME_MONOTONIC`.

If it can't be found in the request. Also support --cmdfile to set it to
a custom file name.
runtests.pl always writes this file with the test number in it since a
while back.
The default target should only build libcurl and curl. Add a dedicated
'testdeps' target which will be used later when running tests. Note that
unittests are currently broken in CMake and already excluded.
Closes#5368
setjmp.h should only be included if HAVE_SETJMP_H is defined.
Add additional log statements to see wether reads and writes
are blocking or finishing before an alarm signal is received.

A common set of functions instead of many separate implementations for
creating buffers that can grow when appending data to them. Existing
functionality has been ported over.
In my early basic testing, the total number of allocations seem at
roughly the same amount as before, possibly a few less.
See docs/DYNBUF.md for a description of the API.

This makes sure that select_ws behaves similar to real select
which stops waiting on a signal handler being triggered.
This makes it possible to gracefully stop sockfilt.exe on
Windows with taskkill /IM sockfilt.exe (without /F force flag).

This commit adds a global exit event to the test servers that
Windows-specific wait routines can use to get triggered if the
program was signaled to be terminated, eg. select_ws in sockfilt.c
The exit event will be managed by the signal handling code and is
set to not reset automatically to support multiple wait routines.

Use raise to trigger signal handler instead of calling it
directly and causing potential unexpected control flow.

FTP, IMAP, POP3, SMTP and their IPv6 versions are now all on dynamic
ports
Test 842-845 are unfortunately a bit hard to move over to this concept
right now and require "default port" still...
The runtests script now always performs variable replacement on the
entire test source file before the test gets executed, and saves the
updated version in a temporary file (log/test[num]) so that all test
case readers/servers can use that version (if present) and thus enjoy
the powers of test case variable substitution.
This is necessary to allow complete port number freedom.
Test 309 is updated to work with a non-fixed port number thanks to this.
With this bit set, my mac successfully resolves "ip6-localhost" when in
fact there is no such host known to my machine! That in turn made test
241 wrongly execute and fail.

Replace the incomplete workaround regarding FD_CLOSE
only signalling once by instead doing a pre-check with
standard select and storing the result for later use.
select keeps triggering on closed sockets on Windows while
WSAEventSelect fires only once with data still available.
By doing the pre-check we do not run in a deadlock
due to waiting forever for another FD_CLOSE event.
Fix race-condition of waiting threads finishing while events are
already being processed which lead to invalid or skipped events.
Use mutex to check for one event at a time or do post-processing.
In addition to mutex-based locking use specific event as signal.

Recent gcc warns when byte count of strncpy() equals the destination
buffer size. Since the destination buffer is previously cleared and
the source string is always shorter, reducing the byte count by one
silents the warning without affecting the result.
Closes#5059
When doing a request with a body + Expect: 100-continue and the server
responds with a 417, the same request will be retried immediately
without the Expect: header.
Added test 357 to verify.
Also added a control instruction to tell the sws test server to not read
the request body if Expect: is present, which the new test 357 uses.

Prior to this change the swsbounce check in service_connection could
fail because prevtestno and prevpartno were not set, which would cause
the wrong response data to be sent to some tests and cause them to fail.
