<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">clang's static analyzer will throw quite a number warnings / errors during compilation, some of which can be very helpfull in finding corner-case bugs
clang compiler warning:-Wtautological-compare
Changes:
/branches/13/channels/pjsip/dialplan_functions.c:869
len is of type size_t, which is unsigned. It will not be able to hold a value < 0
/branches/13/funcs/func_curl.c:174
Not a 100% sure how to do this correctly. But assiging a negative value is problematic. Extending the enum in curl/curl.h is not possible either. I opted to use the enum last entry (CURL_LAST) which is currently not used for any thing. Another option would be to use one of the OBSOLETE VALUES like 16. Neither way is very nice though.
/branches/13/include/asterisk/app.h:988
Needed to convey the error state returned by res/res_stasis_recording.c:stasis_app_recording_if_exists_parse
/branches/13/include/asterisk/cel.h:77
Added to convey not-found or error state. Not sure which name would be prefered for such an enum value.
/branches/13/main/cel.c:536
Return actual enum instead of -1,l which can not be conveyed by this enum.
/branches/13/main/enum.c:260
dn_expand return signed int
/branches/13/main/event.c:202
enum type cannot be < 0
/branches/13/main/indications.c:362
tone_data.freq1 and freq2 are unsigned int's so no need to check if < 0. Not sure what should happend when freq1 / freq2 are 0 already... (needs recheck by source owner)
/branches/13/main/presencestate.c:293
Should use the actual enum value for INVALID State
/branches/13/main/security_events.c:432/890/1176/
enum event_type cannot be <0
/branches/13/main/udptl.c:365/649/661
encode_length returns and unsigned int, so checking if < 0 does not make sence. Not 100% if encode_length has side effects, so left the actual call the this function in place. (Needs to be rechecked by code-owner)
/branches/13/res/res_pjsip_exten_state.c:411
Used a temporary int variable to be able to check the return value from ast_hint_presence_state.. Not very nice, but did not want to change the signature of this function.
/branches/13/res/res_stasis_playback.c:634
operation is enum and cannot be < 0
/branches/13/res/res_stasis_recording.c:598/604
recording->state / operation is enum and cannot be < 0
/branches/13/res/res_security_log.c:992
enum event_type cannot be <0
use of ARRAY_IN_BOUNDS with enum results in tautological comparison for the lower limit which is always true.</pre>
