Added several unit tests for coap_get_uri_path():
* Check corner cases such as one or more zero-length Uri-Paths.
* Check percent-encoding of reserved characters.
* Check non-reserved characters that should not be percent-encoded.
This change also removes a couple of trailing LWS by accident.
A simple structure for (D)TLS-specific unit tests has been added.
Currently, only general support and the version number as reported
by coap_get_tls_library_version() are checked.
As unit tests with IPv6 addresses keep failing on docker-based
travis CI, this changes reverts to IPv4 usage in following files:
test_wellknown.c
test_sendqueue.c
Make coap_pdu-t independent of the header style.
Use C99 sized types when applicable.
Use transaction ids in host byte order in the library.
Make coap_pdu_t payload storage grow on demand.
Add parsing and encoding of PDUs with UDP or TCP style headers.
Adapt examples and unit tests to the new PDU format.
When building outside the source tree compilation fails on
examples, because the libcoap headers expect to be all in the
same directory but coap.h is generated under the build
directory, so it is necessary to add an extra include path
for it.
Also, build directories should always appear before source
directories in the include path, so that any leftover
generated files in the source tree are ignored.
Sendqueue nodes and send operations now require a session object.
This modification calls coap_new_client_session() on a global
coap_context_t object to create a fake session on the loopback
interface.
Merge changes from PR #47 related to windows platform support.
Add full windows platform support including correct error checking and working regression tests and examples.
Remove need to build applications using libcoap with -DWITH_POSIX and to include coap_config.h. This applies to the examples as well.
PR #65 reports wrong encoding of option value 269. The new
unit test t_encode_option9() tests for correct encoding
according to [RFC 7252, Section 3.1](https://tools.ietf.org/html/rfc7252#section-3.1).
Free the storage allocated by coap_new_error_response() in unit tests.
This change simplifies automated leak checks as it avoids cluttering
the output with almost false positives.
The build environment was lacking the possibility to get libcoap
buildable out of tree, simply checkable by the running 'make distcheck'.
Without this fix the users are impossible to build libcoap in a own
folder that's independed from the source containing folder. Typical use
case would be:
$ mkdir libcoap-build && cd libcoap-build
$ /path/to/libcoap-source/configure \
--srcdir=/path/to/libcoap-source \
--prefix=/somethere/to-install
This commit enables the out of tree build by adding and changing some
needed variables.
The CUNIT_LIBS are already used, the CUNIT_CFLAGS are also needed to
ensure that get also header files that are not inside the default search
patch of the compiler. For example header within /usr/local/include
instead /usr/include.
CUNIT_LIBS and CUNIT_CFLAGS are generated by PKG_CHECK_MODULES([CUNIT] ...
in configure.ac.
The testdriver was linked against the statically generated library of
libcoap. By this the testdriver will *always* find any symbols, no
matter if it is a private or public symbol.
Due this the testing behavior isn't the same as a user would use the
shared library and can get a potentially pitfall even if the testdriver
was successful.
Due previous changes to the public header the testdriver source needs
now the local header coap_config.h to find all needed functions so there
are small changes needed to the source files.
Some unit tests in tests/test_options.c and tests/test_pdu.c check
for error cases, causing warning messages to be emitted by the
library code. As the expected result is checked separately, the
warnings can be suppressed to avoid confusion.
Doing up some housekeeping around the used CFLAGS.
To be more generic put the default declaration for additional warning
CFLAGS into configure.ac and clean up the Makefile.am's.
There are the default CFLAGS variable that is a global variable if not
re adjusted inside the different targets.
The second variable for CFLAGS is the AM_CFLAGS definition that is used
inside a Makefile as a global variable.
There is also the possibility to graduate the CFLAGS for a single
target. But currently there are nothing more than one target within each
Makefile so we can set for now the target specific CFLAGS to the
AM_CFLAGS.
A new variable called WARNING_CFLAGS is inside the configure.ac created,
this variable holds all the warnings flags inside. The Makefile.am's are
taking the values and is setting the variable AM_CFLAGS which is used in
the target specific CFLAGS. Also the options 'DWITH_POSIX' and
'D_GNU_SOURCE' are now appended to the CFLAGS if the configure script is
detecting a *-[uc]linux* system.
To let the previous added configure option '--enable-tests' really build
the testdriver binary adding the needed changes to the files in the main
folder.
Finally adding a new Makefile.am within the tests/ folder.
The subdirectory "tests" now contains a growing set of unit tests for the
libcoap API. To use this, you will need CUnit (see http://cunit.sourceforge.net)
and must configure with the option --with-tests.
