* Problem: zmq_z85_decode does not validate its input
Solution: added checks for invalid characters and overflows
* Added tests, added further check for range overflow, removed (multiple) calls to strlen
* Problem: gcc fails to build
Solution: added missing include directive
* Added VS2015 test_utils_z85 project
* Fixed indentation and copyright notice
* Resolved garbage from merge
* Revert "Added VS2015 test_utils_z85 project"
This reverts commit c58b3c664c.
* Problem: test calls zmq_z85_decode with a NULL dest
Solution: call zmq_z85_decode with a properly sized buffer
* Problem: tests for zmq_z85_* scattered over two files
Solution: merged files
* Removed reference to removed test file from CMakeLists.txt
* Problem: Missing include directive to stdint.h
Solution: Added include directive
* Define __STDC_LIMIT_MACROS before including stdint.h
* Problem: Wrong variable is checked for invalid character marker
Solution: Use correct variable
- they have no copyright / license statement
- they are in some randomish directory structure
- they are a mix of postable and non-portable files
- they do not conform to conditional compile environment
Overall, it makes it rather more work than needed, in build scripts.
Solution: clean up tweetnacl sauce.
- merged code into single tweetnacl.c and .h
- standard copyright header, DJB to AUTHORS
- moved into src/ along with all other source files
- all system and conditional compilation hidden in these files
- thus, they can be compiled and packaged in all cases
- ZMQ_USE_TWEETNACL is set when we're using built-in tweetnacl
- HAVE_LIBSODIUM is set when we're using external libsodium
It's unclear which we need and in the source code, conditional code
treats tweetnacl as a subclass of libsodium, which is inaccurate.
Solution: redesign the configure/cmake API for this:
* tweetnacl is present by default and cannot be enabled
* libsodium can be enabled using --with-libsodium, which replaces
the built-in tweetnacl
* CURVE encryption can be disabled entirely using --enable-curve=no
The macros we define in platform.hpp are:
ZMQ_HAVE_CURVE 1 // When CURVE is enabled
HAVE_LIBSODIUM 1 // When we are using libsodium
HAVE_TWEETNACL 1 // When we're using tweetnacl (default)
As of this patch, the default build of libzmq always has CURVE
security, and always uses tweetnacl.
Of course people still "can" distributed the sources under the
LGPLv3. However we provide COPYING.LESSER with additional grants.
Solution: specify these grants in the header of each source file.
zmq_atomic_counter_dec returned a 'bool' value, yet this isn't
defined by standard, so causes compile errors in upstream code.
Solution: return an int that can be safely converted to bool if
needed by bindings.
Solution: as libzmq already provides this across all platforms,
expose an atomic counter API. I've not wrapped atomic pointers,
though someone who needs this may want to do so.
* Removed redundant Z85 code and include files from project
* Simplified use of headers in test cases (now they all just use testutil.hpp)
* Export zmq_z85_encode() and zmq_z85_decode() in API
* Added man pages for these two functions
Copyrights had become ads for Sustrik's corporate sponsors, going against the original
agreement to share copyrights with the community (that agreement was: one line stating
iMatix copyright + one reference to AUTHORS file). The proliferation of corporate ads
is also unfair to the many individual authors. I've removed ALL corporate title from
the source files so the copyright statements can now be centralized in AUTHORS and
source files can be properly updated on an annual basis.
