2016-11-16build: make check: disable sim_test when built with --disable-pcscNeels Hofmeyr3-2/+8
Numerous issues caused sim_test to be attempted even though libosmosim was not built: In configure.ac, the ENABLE_PCSC variable lacked an AC_SUBST() to be exported. Furthermore in configure.ac, no value 'yes'/'no' was assigned to the ENABLE_PCSC variable, only to the enable_pcsc value. In testsuite.at, encapsulating the sim_test in 'if ENABLE_PCSC' seems to have no effect, regardless (not even when using a variable that should be defined accurately). So fix with these steps, similarly to how we do it in openbsc: In AC_ARG_ENABLE, directly use 'ENABLE_PCSC' to assign 'yes'/'no'. Export the same using AC_SUBST(). Add tests/atlocal.in to translate ENABLE_PCSC to enable_sim_test (also add atlocal to AC_OUTPUT and distclean). Use enable_sim_test in testuite.at, as seen in openbsc: use AT_CHECK() to indicate skipping the test if enable_sim_test isn't 'yes'. Change-Id: I9e8740c7d2dfbd272e22fee85972ef3fda7184a8
2016-11-10bitcomp: Remove the t4 decoding from libosmocoreHolger Hans Peter Freyther2-22/+0
As outlined by mail on the 13th of July the tree based approach to decoding in the PCU is faster by order of magnitude. Instead of having a slow implementation in the library and a quick one in the PCU, let's only have a quick one in the PCU and at some point in the future move it to libosmocore. Execute the plan and remove t4_decode. Change-Id: I021424444625a097560d086c217c81eac4a5ee44
2016-11-08Add logging and testing for FSM deallocationMax1-4/+5
osmo_fsm_inst_alloc() logs allocation but osmo_fsm_inst_free() is silent. Fix this by adding log message for deallocation to make FSM lifecycle tracking easier. Also make sure it's covered by test suite. Change-Id: I7e5b55a1fff8e36cf61c7fb61d3e79c1f00e29d2

2016-09-26bitrev_test: don't omit last byte from test result checkNeels Hofmeyr2-25/+28
The osmo_hexdump of the output in sh_chk() omitted the last byte of the returned bytes from the osmo_nibble_shift_*() functions. Determine the number of bytes from nibbles divided by two plus one for any odd nibble number. Output this number of bytes of output data. Memset the output buffer to get well-defined bytes for unwritten places. Also assert that we have enough buffer length for all nibbles. Change-Id: I011f42bca555caec0dfe8688ff1f28303fa04fad

2016-09-22timer_test: do not use real time: deterministic and fasterNeels Hofmeyr1-20/+15
Use osmo_gettimeofday_override* to decouple the timer test from real time. No longer call osmo_select_main(), since select() actually waits for real time. This reduces the timer_test to the osmo_timer_* logic and excludes the real time and osmo_timers_nearest() accuracy testing with actual waiting involved. This may be seen as a loss, but is more fit for a test suite. The main point here is to get deterministic results in jenkins, so that we don't have to retrigger jobs based on timing failures; added bonus is that the test runs much faster now.

When a timer was late, show the timing details. Also count whether timers fired early, for completeness' sake. Change-Id: Id3942637d77a28b5092ffffcc3e6d9d67c2b8e68
2016-09-22fix timer_test: don't forget to set tv_usec on the stop timeNeels Hofmeyr1-0/+1
The timer_test schedules timers and records the desired stop time. Also store the usec value of the desired stop time, because scheduling at e.g. sec N usec 999999 but recording sec N usec 0, and then receiving a timer at sec N+1 usec 0 is only 1 usec late, but records as 1000000 usecs late. This might have been the main cause of the timer test not working well on the osmocom build server. Change-Id: I13bb60f7d341a397f95d13d9c63c40188b6cd5a0
2016-09-10build: tests: don't link system installed libosmogsm.Neels Hofmeyr1-5/+10
Add src/gsm/libosmogsm.la explicitly to some test linkages, because otherwise the linker would pick the libosmogsm already installed on the system instead of the one that was just built in the source tree. I noticed because a libosmogsm needing some more symbols from libosmocodec was still installed, while the patch that cause it was already removed. Thus I caught all(?) test binaries that linked libosmogsm from $PREFIX. Change-Id: Ie61d60e1506f16de20add70fd0f44ebfa7a00a75

Move those routines from OpenBSC to libosmogsm, so they can be re-used from other programs. I think it was a mistake to add them only inside the openbsc repository in the first place. We need to pay more attention to this in the future.

If argument given it'll be interpreted as intended output directory, otherwise current working directory is used. Codes for *CCH, CS2/3 and TCH/AFS are generated. Corresponding manual implementations are removed from tests. This introduce build-time dependency on python. The main work for this patch was generously contributed by Sylvain Munaut. Fixes: OS#1629

2016-01-30bivec: Fix the output of the testcaseHolger Hans Peter Freyther2-12/+16
osmo_hexdump_nospc/osmo_hexdump is an old school C routine with a static internal array. This means that printf will most likely one of the two strings twice. For Linux/glibc this is the first string (for whatever reason?) and for FreeBSD it is the last call of the osmo_hexdump_nospc. We could have noticed by both strings being of the same length besides the different length input. The second issue is that we cast a hexstring to uint8_t and dump the string as hex. So the two strings should not match at all. Fix it by printing the hex string as plain hex and separating the two printf calls. Update the test output.
2016-01-30bitvec: Test and fix regression for C++->C conversionHolger Hans Peter Freyther2-0/+31
bitvec_read_field/bitvec_write_field in the PCU used a C++ reference and when porting to C it was decided to pass the parameter by value and this lost the "back propagation" of the new index. Change the parameter to be an in/out parameter and this way do not have a silent semantic break in the osmo-pcu (where we copy the reference in csn.1 by value) and have a true compile failure. Add Max's simple test for bitvec_unhex function leaving the checking of bitvec_read_field and the side effect in the datastructure about the number of bits still open.

2016-01-15msgb/test: Add functions to catch and check exceptionsJacob Erlbeck2-1/+32
Currently the msgb error handling cannot be fully tested, since in many cases osmo_panic will be called. This will in turn call abort(). Using an osmo_panic_handler that just returns will not help, since many msgb functions rely on MSGB_ABORT to not return at all. This commit uses an alternative osmo_panic_raise handler that just calls longjmp to return to the test function. Since some of this activity is logged to stderr where the strings may contain variable parts like pointer addresses, stderr checking is disabled in testsuite.at. Sponsored-by: On-Waves ehf

While the bytes in the bitvecs do not need to be aligned, the uint8_t arrays always are. In case the bytes in the bitvec are aligned, the implementation uses memcpy.

2015-12-17ns: Force a defined state when sending NS RESETJacob Erlbeck2-0/+102
Currently the state is assumed to remain the same while the reset procedure is active. While this works correctly in general, a single unexpected BLOCK_ACK or UNBLOCK_ACK can change the state but will not stop the reset procedure. The leads to repeated RESET messages, where the corresponding RESET_ACK is ignored. This is a stable state which can only be left by manual intervention or by reception of a RESET message from the peer. This commit changes the RESET timeout handler to set the state to BLOCKED/RESET when sending the new NS RESET message. Note that this should ensure a clean restart even if the state has been screwed up. It does not fix the handling of BLOCK_ACK or UNBLOCK_ACK in abnormal cases.
