* fsm: term: get parent pointer as late as possibleNeels Hofmeyr2016-12-241-1/+4
| | | | | | | | | | | | During FSM instance termination, fetch the parent pointer every time just before using it, in case the child termination or cleanup callback wish to change anything about the parent, e.g. to prevent event dispatch. This patch was created to try and fix a problem that was in the end solved differently. There is no actual need or use case for this at the moment, but it generally makes sense to get the parent pointer as late as possible. Change-Id: I999d7f29ba10281d4005c5163130bb2d80148362
* utils/conv_gen.py: separate code definitionsVadim Yanitskiy2016-12-242-714/+728
| | | | | | | | | This change separates the convolutional code definitions from the code generator logic, allowing us to make further changes in more specific way. For example, adding some new codes, you change the conv_codes.py only because such change isn't related to the generator. Change-Id: I3428561251b7d7a180d1e9b6fcaad50bdbbc37fa
* utils/conv_gen.py: use shared tables if possibleVadim Yanitskiy2016-12-241-37/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | This change introduces the memory usage optimization, mentioned in d2d9760c08f35a231d32f0ebeb73b2927e5573b3. The aim is to make code generator able to detect, whether the same tables are used by several convolutional code definitions, and prevent one from writing these tables multiple times. For now, the detection process isn't fully automatic, so all shared polynomials should be placed inside the 'shared_polys' dictionary, for example: shared_polys = { "xcch" : [ ( G0, 1 ), ( G1, 1 ), ], "mcs" : [ ( G4, 1 ), ( G7, 1 ), ( G5, 1 ), ], } Change-Id: I84760f5cdfdaece376b801d2e6cb2954ee875a3b
* fsm: factor out osmo_fsm_inst_term_children() from osmo_fsm_inst_term()Neels Hofmeyr2016-12-242-20/+55
| | | | | | | | | | | | | | | | | | | | osmo_fsm_inst_term() has code for safe child removal, publish that part as osmo_fsm_inst_term_children(); also use from osmo_fsm_inst_term(). As with osmo_fsm_inst_term(), add osmo_fsm_inst_term_children() macro to pass the caller's source file and line to new _osmo_fsm_inst_term_children(). Rationale: in openbsc's VLR, I want to discard child FSMs when certain events are handled. I could keep a pointer to each one, or simply iterate all children, making the code a lot simpler in some places. (Unfortunately, the patch may be displayed subobtimally. This really only moves the children-loop to a new function, replaces it with a call to _osmo_fsm_inst_term_children(fi, OSMO_FSM_TERM_PARENT, NULL, file, line) and drops two local iterator variables. No other code changes are made, even though the diff may show large removal + addition chunks) Change-Id: I8dac1206259cbd251660f793ad023aaa1dc705a2
* fsm: move LOGPFSMSRC and LOGPFSMLSRC to .hNeels Hofmeyr2016-12-242-13/+13
| | | | | | | | | | | LOGPFSM and LOGPFSML are in the header file, put the *SRC variants also there so users of the osmo_fsm_inst API may conveniently create own functions that log the caller's source file and line. Very useful if many action functions call the same event dispatching function, like foo_fsm_done(), and one needs to know which of the callers to debug.

* fsm: term: safer iteration to remove all child FSMsNeels Hofmeyr2016-12-201-4/+20
| | | | | | | | | | | | When terminating child FSMs, restart iteration after every child, to make sure that we don't terminate a child twice. Terminating one child may emit events that in turn terminates other children. I created this patch because at first it looked like the cause of a bug, which turned out not to be the case. So I have no actual use case of this situation, but it does generally make sense to me, so submitting this. Change-Id: I00990b47e42eeb43707a9a42abcd9df52fe5f483

* fsm: explicitly log removal from parent fsmNeels Hofmeyr2016-12-161-0/+3
| | | | | | | | | | | Since removing an FSM from its parent twice causes a segfault, it is very interesting to see when that is attempted. Removing could be made more robust, but logging is interesting for investigating why an FSM is being removed twice in the first place (currently the case in openbsc's vlr_lu_fsm).

* fsm: log caller's source for events and state changes, not fsm.c linesNeels Hofmeyr2016-12-143-27/+103
| | | | | | | | | | | | | | | | | | | | | | | When looking at log output, it is not interesting to see that a state transition's petty details are implemented in fsm.c. Rather log the *caller's* source file and line that caused an event, state change and cascading events. To that end, introduce LOGPSRC() absorbing the guts of LOGP(), to be able to explicitly pass the source file and line information. Prepend an underscore to the function names of osmo_fsm_inst_state_chg(), osmo_fsm_inst_dispatch() and osmo_fsm_inst_term(), and add file and line arguments to them. Provide the previous names as macros that insert the caller's __BASE_FILE__ and __LINE__ constants for the new arguments. Hence no calling code needs to be changed. In fsm.c, add LOGPFSMSRC to call LOGPSRC, and add LOGPFSMLSRC, and use them in above _osmo_fsm_inst_* functions. In addition, in _osmo_fsm_inst_term(), pass the caller's source file and line on to nested event dispatches, so showing where a cascade originated from.

* fsm: add LOGPFSML to pass explicit logging levelNeels Hofmeyr2016-12-143-12/+12
| | | | | | | | | | | | | | Provide one central LOGPFSML to print FSM information, take the FSM logging subsystem from the FSM instance but use an explicitly provided log level instead of the FSM's default level. Use to replace some, essentially, duplications of the LOGPFSM macro. In effect, the fsm_test's expected error changes, since the previous code dup for logging events used round braces to indicate the fi's state, while the central macro uses curly braces.

* fix logging: log_set_category_filter() for internal DL* logging catsNeels Hofmeyr2016-12-122-1/+3
| | | | | | | | | | | | | | | | | | In log_set_category_filter(), passing a negative index lead to memory corruption. Particularly dangerous since the internal logging categories have negative values. Fix: apply map_subsys() to interpret negative values as internal logging categories. As a side effect, out-of-bounds logging categories will be mapped to DLGLOBAL instead of being dropped. Fix the expectations in logging_test to match the fixed bug. While at it also guard against a NULL logging target. Change-Id: Ib0725b22bc39498c6b3970a61eb3339cf56d19f1
* show bug in logging: log_set_category_filter on DL* categoriesNeels Hofmeyr2016-12-121-0/+6
| | | | | | | | | | | | | | Add a check to logging_test.c to show a bug: passing an internal DL* category constant to log_set_category_filter() results in a negative array index and undefined behavior. A sanitize build should catch this. The bug is confirmed by the fact that logging_test.err stays the same (hopefully) although a logging output should appear from this patch. The test could as well segfault or anything else, it's a bit of a gamble. This bug will be fixed along with the expectation in a subsequent patch. Change-Id: Ie2da77c642a84cafc0f528985930697ec167183b
* fix logging: out-of-bounds check should end with user categoriesNeels Hofmeyr2016-12-122-0/+6
| | | | | | | | | | | | | To check category bounds, rather use num_cat_user, to redirect all semantically unknown categories to DLGLOBAL. Adjust logging_test expectations accordingly: "(d)" is now also shown. Note: subsys is and needs to be signed, while num_cat* are unsigned. Thus for a negative subsys, 'subsys >= num_cat_user' practically always yields true. Pay close attention to signedness and check upper bound only for positive values. Change-Id: I4a952b759f30d90fbfb81fedcfc56a8092ea18c1
* show bug in logging: out-of-bounds check should end with user categoriesNeels Hofmeyr2016-12-122-0/+5
| | | | | | | | | | | | | | | | | | | In the background osmo_log_info array, the user's logging categories are enhanced by the library internal ones. So far logging category range checking only checked for the larger array bounds, although passing a logging category >= num_cat_user is already semantically unknown and should redirect to DLGLOBAL. Add a check to logging_test.c to show that this isn't happening. Instead of DLGLOBAL, a logging category that happens to be at that index is queried. The bug is confirmed by logging_test.err only showing "(e)" and not "(d)": "(e)" is shown because the first category after the user ones happens to be DLGLOBAL. "(d)" is omitted since it hits a category that's not on debug level. This bug will be fixed along with the expectation in a subsequent patch. Change-Id: I397278714018ee9a0ae5101515f31ddddf79c2ec
