7 dayslogging: Introduce mutex API to manage log_target in multi-thread envsPau Espin Pedrol1-0/+14
log_enable_multithread() enables use of locks inside the implementation. Lock use is disabled by default, this way only multi-thread processes need to enable it and suffer related complexity/performance penalties. Locks are required around osmo_log_target_list and items inside it, since targets can be used, modified and deleted by different threads concurrently (for instance, user writing "logging disable" in VTY while another thread is willing to write into that target). Multithread apps and libraries aiming at being used in multithread apps should update their code to use the locks introduced here when containing code iterating over osmo_log_target_list explictly or implicitly by obtaining a log_target (eg. osmo_log_vty2tgt()).

2019-06-13minor: don't redefine macrosKévin Redon1-0/+2
the DEBUG macro name and ARRAY_SIZE macro function are frequently used in other projects. If these projects also use libosmocore, the macros will be redefined. This also generates a warning message during compilation. Not redefining the macros removes the warning message and possible (but unlikely) mis-redefinition.

2018-09-13logging vty: rewrite 'logging level' vty cmd generationNeels Hofmeyr1-4/+0
Completely drop the implementations of log_vty_command_{str,description}(). These functions have been public API once, marked as deprecated since c65c5b4ea075ef6cef11fff9442ae0b15c1d6af7 (March 2017). I considered to keep them, or reduce them to useless stubs, but it is quite silly, really. These functions are completely and utterly useless outside of libosmocore. Any program linking these deserves to fail. Re-implement vty logging level command gen, in logging_vty.c. logging.c is simply the wrong place for that. Introduce logging_internal.h to share logging definitions to logging_vty.c without publishing as API. Introduce static gen_logging_level_cmd_strs() to compose a list of category arguments with their descriptions for VTY commands. Use osmo_talloc_asprintf() instead of the previous error prone and chaotic strlen() counting method. Do not dynamically generate log level arguments, just keep static strings. We are super unlikely to ever change the log levels we have. No changes in logging_vty_test.vty: proves that there is no functional change. All of this, besides introducing basic sanity, is cosmetic preparation to be able to re-use the generic command generation code for arbitrary commands with category or level args (for deprecated and new keywords). Rationale: I want to hide 'all' and 'everything' from the VTY command documentation, by means of deprecating. I first tried to simply define a deprecated 'logging level CAT everything' command: logging level (all|rsl|rr|...) (debug|info|notice|error|fatal) logging level CAT everything # <- deprecated and hidden But unfortunately, command matching doesn't work as intended when the CAT argument reflects a valid category; I want it to invoke the deprecated function as soon as the 'everything' keyword follows, but it stays stuck to the "valid" command when the category argument matches an explicit keyword in that list, and will throw an error on the following 'everything' keyword. I.e.: logging level rsl everything % Unknown command # <-- leads to config file parse error logging level unknown_string everything % Ignoring deprecated 'everything' # <-- works only for invalid categories So I need to define 'everything' separately, again with a list of each valid category instead of a generic CAT arg.

2018-08-27log: add 'last' option to 'logging print file'Neels Hofmeyr1-0/+9
Allow printing the source file information *after* the log information. Add target->print_filename_pos, log_set_print_filename_pos() and enum log_filename_pos, and the optional 'last' keyword to the 'logging print file' vty command. (An enum in case we want to add other positions later.) Rationale: on log lines, the logging context is usually printed first in the logging text. Without the source file information, this logging context pretty much aligns in an easily readable way. When adding the source file information, each line's logging context info is shifted right by a pretty much random amount and it is hard to spot recurring logging contexts. One solution is to switch off source file info, of course, but that's not an option when actively hacking on bugs and new features. For example, it is unnecessarily hard to spot lchan FSM related log lines in this osmo-bsc log snippet: DRSL NOTICE mgw_endpoint_fsm.c:603 mgw-endpoint(conn0){WAIT_MGW_RESPONSE}: Freeing instance DRSL NOTICE fsm.c:381 mgw-endpoint(conn0){WAIT_MGW_RESPONSE}: Deallocated DMSC NOTICE mgw_endpoint_fsm.c:603 SUBSCR_CONN(conn0){CLEARING}: Received Event FORGET_MGW_ENDPOINT DCHAN DEBUG lchan_rtp_fsm.c:741 lchan(0-0-1-TCH_F-0){WAIT_RLL_RTP_ESTABLISH}: Received Event LCHAN_EV_RTP_RELEASED DCHAN DEBUG lchan_rtp_fsm.c:520 lchan_rtp(0-0-1-TCH_F-0){ROLLBACK}: Freeing instance DCHAN DEBUG fsm.c:381 lchan_rtp(0-0-1-TCH_F-0){ROLLBACK}: Deallocated DCHAN DEBUG lchan_rtp_fsm.c:520 lchan(0-0-1-TCH_F-0){WAIT_RLL_RTP_ESTABLISH}: Received Event LCHAN_EV_RTP_RELEASED DCHAN DEBUG lchan_fsm.c:1232 lchan(0-0-1-TCH_F-0){WAIT_RLL_RTP_ESTABLISH}: state_chg to WAIT_RF_RELEASE_ACK DRSL NOTICE handover_fsm.c:762 handover(interBSCin_conn0){WAIT_RR_HO_DETECT}: Terminating (cause = OSMO_FSM_TERM_REGULAR) DRSL NOTICE handover_fsm.c:762 handover(interBSCin_conn0){WAIT_RR_HO_DETECT}: Freeing instance DRSL NOTICE fsm.c:381 handover(interBSCin_conn0){WAIT_RR_HO_DETECT}: Deallocated DCHAN DEBUG lchan_fsm.c:1196 lchan(0-0-1-TCH_F-0){WAIT_RF_RELEASE_ACK}: state_chg to BORKEN DCHAN DEBUG lchan_fsm.c:354 lchan(0-0-1-TCH_F-0){BORKEN}: (type=TCH_F) Clearing lchan state DLMGCP DEBUG mgcp_client.c:741 Tx MGCP msg to MGCP GW: 'DLCX 3 2@mgw MGCP 1.0' DLMGCP DEBUG mgcp_client.c:743 Sending msg to MGCP GW size: 66 DRLL NOTICE mgcp_client_fsm.c:422 MGCP_CONN(to-BTS){ST_DLCX_RESP}: Received Event EV_DLCX_RESP Placing the source file info behind the log text makes it much easier to follow, while the source file info is still available: DRSL NOTICE mgw-endpoint(conn0){WAIT_MGW_RESPONSE}: Freeing instance (mgw_endpoint_fsm.c:603) DRSL NOTICE mgw-endpoint(conn0){WAIT_MGW_RESPONSE}: Deallocated (fsm.c:381) DMSC NOTICE SUBSCR_CONN(conn0){CLEARING}: Received Event FORGET_MGW_ENDPOINT (mgw_endpoint_fsm.c:603) DCHAN DEBUG lchan(0-0-1-TCH_F-0){WAIT_RLL_RTP_ESTABLISH}: Received Event LCHAN_EV_RTP_RELEASED (lchan_rtp_fsm.c:741) DCHAN DEBUG lchan_rtp(0-0-1-TCH_F-0){ROLLBACK}: Freeing instance (lchan_rtp_fsm.c:520) DCHAN DEBUG lchan_rtp(0-0-1-TCH_F-0){ROLLBACK}: Deallocated (fsm.c:381) DCHAN DEBUG lchan(0-0-1-TCH_F-0){WAIT_RLL_RTP_ESTABLISH}: Received Event LCHAN_EV_RTP_RELEASED (lchan_rtp_fsm.c:520) DCHAN DEBUG lchan(0-0-1-TCH_F-0){WAIT_RLL_RTP_ESTABLISH}: state_chg to WAIT_RF_RELEASE_ACK (lchan_fsm.c:1232) DRSL NOTICE handover(interBSCin_conn0){WAIT_RR_HO_DETECT}: Terminating (cause = OSMO_FSM_TERM_REGULAR) (handover_fsm.c:745) DRSL NOTICE handover(interBSCin_conn0){WAIT_RR_HO_DETECT}: Freeing instance (handover_fsm.c:745) DRSL NOTICE handover(interBSCin_conn0){WAIT_RR_HO_DETECT}: Deallocated (fsm.c:381) DCHAN DEBUG lchan(0-0-1-TCH_F-0){WAIT_RF_RELEASE_ACK}: state_chg to BORKEN (lchan_fsm.c:1196) DCHAN DEBUG lchan(0-0-1-TCH_F-0){BORKEN}: (type=TCH_F) Clearing lchan state (lchan_fsm.c:354) DLMGCP DEBUG Tx MGCP msg to MGCP GW: 'DLCX 3 12@mgw MGCP 1.0' (mgcp_client.c:741) DLMGCP DEBUG Sending msg to MGCP GW size: 67 (mgcp_client.c:743) DRLL NOTICE MGCP_CONN(to-BTS){ST_DLCX_RESP}: Received Event EV_DLCX_RESP (mgcp_client_fsm.c:422) Implementation: for 'last', insert source file info only when an '\n' is found at the end of the log line composition buffer, so that LOGP()...LOGPC() constructs also print source file info only when a log line actually ends.

2018-08-20use __FILE__, not __BASE_FILE__Neels Hofmeyr1-6/+6
The intention was to use the file's basename, but __BASE_FILE__ means "the root file that is being parsed and contains #include statements". If we had a function using __BASE_FILE__ and that was defined in an #included file, __BASE_FILE__ would indicate the first file where the #include is, and not the file where the function is defined. __BASE_FILE__ works for us because we don't ever include function definitions that log something, so __BASE_FILE__ always coincides with __FILE__ for our logging; but still __BASE_FILE__ is semantically the wrong constant.

2018-01-19logging: separate the '<000b>' subsys from filename loggingNeels Hofmeyr1-1/+13
Add a separate flag and API to switch the category-in-hex output: log_set_print_category_hex(). Add log_set_print_filename2() to modify only the print_filename flag. The old log_set_print_filename() function still affects both flags. Explain the rationale in the comment for log_set_print_filename(). There is no need to deprecate log_set_print_filename(); it might cause compiler warnings and break strict builds unnecessarily. Add VTY command 'logging print category-hex (0|1)'. Since there is no VTY command to switch filename output, nothing needs to be adjusted there (a command will be added in a subsequent patch). Change-Id: Iba03a2b7915853c6dccaf6c393c31405320538b4

Re-introduce the legacy definitions to redirect to the new ones and re-establish backwards compatibility.

2017-02-22logging: centrally define ctx and filter indexesNeels Hofmeyr1-2/+17
It is too easy for calling code to use the same filter and context indexes for different filters and structs. For example, openbsc's IMSI filter and libgb's GPRS_BVC filter both fall on index 1 even though there are plenty more indexes to choose from. To alleviate this, have one central definition here, sort of like ports.h does for VTY and CTRL port numbers. Add static asserts to make sure the indexes fit in the available array and bit mask space. Calling code like openbsc.git and osmo-pcu need adjustments and/or should move to using these enum values instead of their local definitions. Taking this opportunity to also prepare for a split of struct gsm_subscriber in openbsc into bsc_subsciber and vlr_subscriber with appropriate separate filter index constants for both subscriber types. Include previous LOG_FILTER_ALL in the LOGGING_FILTER_* enum, and replace its use by (1 << LOGGING_FILTER_ALL). Change-Id: I5c343630020f4b108099696fd96c2111614c8067

2016-12-14fsm: log caller's source for events and state changes, not fsm.c linesNeels Hofmeyr1-4/+23
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.

2016-12-11fix: DLGSUP logging category "unusable"0.9.5Neels Hofmeyr1-1/+1
All DL* categories are typically negative, but DLGSUP isn't, and it's also not in libosmocore's internal_cat array. See: 3b6fb0880c3ab1e23a3d7d738d073b00c2a794c2 This means that a program using DLGSUP has to include DLGSUP in its own logging cat array (typically not needed for DL* categories), which means for osmo-nitb that DLGSUP (11) replaces DMGCP (also 11), and DMGCP becomes unusable. Fix this: make DLGSUP -11 and include in internal_cat. In gsup_test.c, no longer add DLGSUP to the logging categories array. External follow-ups are otherwise needed only in osmo-hlr.git and some pending patches for openbsc (Id3938267fa062e1a997d3704cd678874306f86ee). Change-Id: Id974c7be158e4d60421a98110f5c807aefd31119

2016-02-29log: Add conditional logging based on log_check_levelJacob Erlbeck1-4/+20
Currently the LOGP/DEBUGP arguments are always evaluated even if no logging will happen at all. This can be expensive, for instance if hexdumps or pretty printed object names are generated. This causes high base load especially on embedded devices and is a major part of CPU usage e.g. of the osmo-pcu.

2016-02-29log: Add log_check_level functionJacob Erlbeck1-0/+1
This commit adds this predicate function which can be used to avoid the execution of code if a certain log level is not enabled. The function will only return 0 (false), if it is sure that a logging call for the same facility and level will not produce any output. This safety criterion shall ensure, that no logging output is lost due to the use of this predicate as a guard. On the other hand, even if the predicate returns != 0 (true), no logging output might get generated by a similar logging command. Note that the current implementation is not focussed on performance, which could be improved by using a lookup table instead of iterating through every target. Sponsored-by: On-Waves ehf
