2018-10-21Fix bad memory accesses during srd_exit()Jon Burgess
When the decoder and session unload functions are called they remove themselves from the list. The code walking the list must be careful to avoid accessing the next pointer which might now be invalid. The g_slist_foreach() takes care of this. Reports from Valgrind before fix: ==175436== Invalid read of size 8 -- ==175436== Address 0xe3f2598 is 8 bytes inside a block of size 16 free'd ==175436== at 0x4C2FDAC: free (vg_replace_malloc.c:530) ==175436== by 0x563C541: g_free (in /usr/lib64/libglib-2.0.so.0.5600.3) ==175436== by 0x5654783: g_slice_free1 (in /usr/lib64/libglib-2.0.so.0.5600.3) ==175436== by 0x56552A2: g_slist_remove (in /usr/lib64/libglib-2.0.so.0.5600.3) ==175436== by 0x4E3FEFF: srd_session_destroy (session.c:343) ==175436== by 0x4E3F5C7: srd_exit (srd.c:311) ==175436== by 0x40336F: test_inst_new (inst.c:40) ==175436== by 0x53E51D5: srunner_run_tagged (in /usr/lib64/libcheck.so.0.0.0) ==175436== by 0x401237: main (main.c:51) ==175436== Block was alloc'd at ==175436== at 0x4C2EBAB: malloc (vg_replace_malloc.c:299) ==175436== by 0x563C435: g_malloc (in /usr/lib64/libglib-2.0.so.0.5600.3) ==175436== by 0x5654056: g_slice_alloc (in /usr/lib64/libglib-2.0.so.0.5600.3) ==175436== by 0x5655797: g_slist_append (in /usr/lib64/libglib-2.0.so.0.5600.3) ==175436== by 0x4E3FC75: srd_session_new (session.c:71) ==175436== by 0x403345: test_inst_new (inst.c:37) ==175436== by 0x53E51D5: srunner_run_tagged (in /usr/lib64/libcheck.so.0.0.0) ==175436== by 0x401237: main (main.c:51)

2018-10-16uart: add support for break condition detectionGerhard Sittig
There are the "traffic inspecting" wait() conditions, which check an edge to find the start of START, then wait for sample points to grab the bit values. Bit times are sampled in their respective center, potential glitches around sample points get ignored. Add another independent set of wait() conditions which check _all_ edges regardless of any data communication. This results in the most reliable and maintainable detection of break conditions, regardless of how they align to data frames. Break is defined as a period of low input signal which spans at least one frame's length. Run the edge inspection after data inspection, which results in the most appropriate annotation output like leading data bits (of incomplete frames), frame errors (violated STOP bit expectations), then break conditions. This approach is most robust in the presence of incomplete input streams.

2018-08-30log: add a public srd_log_callback_get() API routineGerhard Sittig
Allow applications to query the currently registered log callback. So they can either restore the previously registered routine, or register another routine _and_ log to the previously registered routine as well.

2018-08-30counter: Let user decide how to handle the initial dead_cycles stateSoeren Apel
edge_off and word_off are not included in the if block because a user may want to use edge_off to dismiss unwanted clocks instead of dead_cycles.

2018-08-30spi: Create the out_bitrate annotation unconditionallyJosef Gajdusek
The start() method is called before the metadata() method, which results in the the out_bitrate instance variable never getting created and ending up as an AttributeError when decoding. (observed with sigrok-cli and VCD file as the input)
2018-08-29edid: Shorten two code snippets.Uwe Hermann
2018-08-29edid: Add support for extension blocks, cleanupsStefan Brüns
Extension blocks are widely used by e.g. HDMI to signal support for audio, colorspaces and much more. Cleanups: - support short forms for annotations - join overlapping annotations, these were unreadable in PV, and the positions were inaccurate (aligned to bytes instead of bits, no notion of used bits in split fields).
2018-08-25install: unbreak installation with Python 3.7 (os.errno)Gerhard Sittig
The os.errno module has not been an official feature. Python 3.7 removed the corresponding import. This broke the installation of decoders. Prefer 'errno' over 'os.errno'.
