2016-12-07	Add support for the new query-based PD v3 decoder API.	Uwe Hermann
	For the time being, both APIs (2 and 3) will remain supported until all decoders have been converted to API version 3. Then, support for API version 2 will be dropped. Decoders using PD v3 API can benefit from both readability improvements as well as performance improvements. Up to 10x speedup has been measured in some situations (depends a lot on the decoder, the amount of data, the amount of edges in the signals, the amount of oversampling etc. etc.). This is only the first set of (basic) performance improvements for libsigrokdecode, there are various additional opportunities for further changes to improve performance. This changeset has been tested to survive a run of all the test-cases in the sigrok-test repo without issues (for the converted PDs), however it is not very well-tested yet, so there might be regressions that need to be addressed.
2015-10-06	util: Factor out Python module load	Daniel Elstner
	Create a utility function for loading a Python module by its name in UTF-8.

2015-10-06	Python: Restrict code to stable ABI subset	Daniel Elstner
	Limit usage of the Python C API to the stable ABI subset as defined by PEP 384. This removes some type definitions and functions which libsigrokdecode made use of. Convert all affected code to suitable API alternatives. Also fix a few leaks that became apparent while working on the code. The most visible change is that PyTypeObject is now an opaque type. Thus, the custom Decoder and srd_logic types are now created on the heap via an alternative API. Unfortunately, since tp_name is now inaccessible, type names had to be removed from the log output. Stack traces after Python exceptions are now formatted by calling into Python, since the trace object C API is no longer available.
2015-09-13	Build: Include <config.h> first in all source files	Daniel Elstner
	Since Autoconf places some important feature flags only into the configuration header, it is necessary to include it globally to guarantee a consistent build.
2015-04-01	Use g_malloc*() consistently, simplify error handling.	Uwe Hermann
	Use g_malloc*() for small allocations and assume they always succeed. Simplify error handling in a few places accordingly. Document the rules in the README file.
2014-07-08	Remove dependency on Python.h from public API header	Marcus Comstedt
	This prevents Python.h from being included into client code, where it can mess things up by e.g. redefining _POSIX_C_SOURCE.
2013-12-11	Easier access to sequences of strings, not just lists.	Bert Vermeulen

2013-05-03	Main header is <libsigrokdecode/libsigrokdecode.h> now.	Uwe Hermann
	This matches the convention used in libsigrok. Potential other headers might end up in libsigrokdecode/, but only libsigrokdecode.h is meant to be #included by frontends directly.
2013-04-23	GPL headers: Use correct project name.	Uwe Hermann

2013-02-09	Doxygen: Mark private functions/variables properly.	Uwe Hermann

2012-05-09	srd: Fix a few Doxygen errors.	Uwe Hermann

2012-03-28	srd: Some more (optional) consistency renames.	Uwe Hermann

2012-03-18	srd: Constify lots more parameters.	Uwe Hermann

2012-02-28	srd: properly return status code	Bert Vermeulen

2012-02-11	Use g_try_malloc/g_free/g_strdup consistently.	Uwe Hermann
	Avoid plain malloc()/free() in sr/srd, especially in the API calls. Also avoid g_malloc() in favor of g_try_malloc(). Use g_strdup() instead of strdup() so that we can use g_free() consistently everywhere. Exceptions: Stuff that is allocated via other libs (not using glib), should also be properly free'd using the respective free-ing function (instead of g_free()). Examples: Stuff allocated by libusb, libftdi, etc. Also, use sr_err() instead of sr_warn() for actual errors. sr_warn() is meant for non-fatal/uncritical warnings.
2012-02-10	srd: s/python/Python/.	Uwe Hermann

2012-02-10	srd: Add/improve g_malloc() error messages.	Uwe Hermann

2012-02-10	srd: Add/use SRD_API/SRD_PRIV macros.	Uwe Hermann
	This is not yet finished, more things should be made private.
2012-02-10	srd: Cosmetics, whitespace, coding-style fixes.	Uwe Hermann

2012-01-26	srd: Remove manual log domain ("srd: ") prefixes.	Uwe Hermann

2012-01-23	srd: use new exception system everywhere	Bert Vermeulen

2012-01-23	srd: minor code cleanup	Bert Vermeulen

2012-01-22	srd: make all debugging and error reporting uniform	Bert Vermeulen

2012-01-21	add py_dictitem_as_str(), more checking in py_attr_as_str()	Bert Vermeulen

2012-01-16	srd: don't decref an object we don't own	Bert Vermeulen

2012-01-15	srd: clean up module loading/unloading, and the decoder struct	Bert Vermeulen
	PDs are now checked for a proper Decoder object, with at least the required attributes. The author, long_desc and func attributes in the decoder object are gone.
2012-01-07	convert data coming in from a PD to C structs	Bert Vermeulen
	This is in preparation for passing annotation data back to the calling frontend, and python data up to the next protocol in the stack.
2012-01-03	sr/srd: Fix left-over #includes.	Uwe Hermann
	The libs themselves should use #include "sigrok.h" etc., while the frontends must use #include <sigrok.h> and so on.
2011-12-28	better python memory management	Bert Vermeulen

2011-12-28	python 3 port	Bert Vermeulen

2011-12-04	refactored PD framework, now using new sigrok.Decoder object	Bert Vermeulen
	This uses the new python unified type/class object API to construct an object for PDs to subclass. The sigrok.Decoder class has a method put() which is implemented as a C function, and receives the PD's object instance as its first parameter.
