- delete unused `HAVE_VARIADIC_MACROS_C99/GCC` feature checks.
(both autotools and CMake.)
- delete duplicate `NULL` check in `Curl_trc_cf_infof()`.
- fix compiler warning in `CURL_DISABLE_VERBOSE_STRINGS` builds.
```
./lib/cf-socket.c:122:41: warning: unused parameter 'data' [-Wunused-parameter]
static void nosigpipe(struct Curl_easy *data,
^
```
- fix `#ifdef` comments in `lib/curl_trc.{c,h}`.
- fix indentation in some `infof()` calls.

Unit tests
The goal is to add tests for all functions in libcurl. If functions are too big and complicated, we should split them into smaller and testable ones.
Build Unit Tests
./configure --enable-debug is required for the unit tests to build. To
enable unit tests, there will be a separate static libcurl built that will be
used exclusively for linking unit test programs. Just build everything as
normal, and then you can run the unit test cases as well.
Run Unit Tests
Unit tests are run as part of the regular test suite. If you have built
everything to run unit tests, to can do 'make test' at the root level. Or you
can cd tests and make and then invoke individual unit tests with
./runtests.pl NNNN where NNNN is the specific test number.
Debug Unit Tests
If a specific test fails you will get told. The test case then has output left
in the %LOGDIR subdirectory, but most importantly you can re-run the test again
using gdb by doing ./runtests.pl -g NNNN. That is, add a -g to make it
start up gdb and run the same case using that.
Write Unit Tests
We put tests that focus on an area or a specific function into a single C
source file. The source file should be named unitNNNN.c where NNNN is a
previously unused number.
Add your test to tests/unit/Makefile.inc (if it is a unit test). Add your
test data file name to tests/data/Makefile.inc
You also need a separate file called tests/data/testNNNN (using the same
number) that describes your test case. See the test1300 file for inspiration
and the tests/FILEFORMAT.md documentation.
For the actual C file, here's a simple example:
#include "curlcheck.h"
#include "a libcurl header.h" /* from the lib dir */
static CURLcode unit_setup( void )
{
/* whatever you want done first */
return CURLE_OK;
}
static void unit_stop( void )
{
/* done before shutting down and exiting */
}
UNITTEST_START
/* here you start doing things and checking that the results are good */
fail_unless( size == 0 , "initial size should be zero" );
fail_if( head == NULL , "head should not be initiated to NULL" );
/* you end the test code like this: */
UNITTEST_STOP
