* address a few minor Visual warningsYann Collet2019-04-181-3/+4
| | | | and created target cxx17build
* fix several minor static analyzer warningsYann Collet2019-04-181-6/+8
|
* added a fake initialization to please an analyzerYann Collet2019-04-151-1/+1
| | | | | which is unable to understand that the variable is necessarily initialized in spite of an assert just before.
* added more margin for canary in frametestYann Collet2019-04-151-5/+4
|
* frametest: removed uninitialized warningYann Collet2019-04-151-17/+26
| | | | was a false positive, but better remove it anyway
* assert() the failed testYann Collet2019-04-151-0/+1
| | | | ensure canary remains within buffer limits
* fixed frametestYann Collet2019-04-151-10/+14
| | | | | | One test could write a canary value out of bound in exceptional conditions involving multiple flushes triggered by -s3421 -t462948.

* added a test for LZ4F_compressEnd()Yann Collet2018-10-091-2/+12
| | | | | | | | | | | | | | | which actively tries to make it write out of bound. For this scenario to be possible, it's necessary to set dstCapacity < LZ4F_compressBound() When a compression operation fails, the CCtx context is left in an undefined state, therefore compression cannot resume. As a consequence : - round trip tests must be aborted, since there is nothing valid to decompress - most users avoid this situation, by ensuring that dstCapacity >= LZ4F_compressBound() For these reasons, this use case was poorly tested up to now.
* tried to clean another bunch of cppcheck warningsYann Collet2018-09-191-5/+6
| | | | | | | | | | | | so "funny" thing with cppcheck is that no 2 versions give the same list of warnings. On Mac, I'm using v1.81, which had all warnings fixed. On Travis CI, it's v1.61, and it complains about a dozen more/different things. On Linux, it's v1.72, and it finds a completely different list of a half dozen warnings. Some of these seems to be bugs/limitations in cppcheck itself. The TravisCI version v1.61 seems unable to understand %zu correctly, and seems to assume it means %u.
* added cppcheckYann Collet2018-09-181-2/+2
| | | | | | as Makefile target and Travis CI test. Fixed last cppcheck warnings in tests and examples
* small extDict : fixed side-effectYann Collet2018-05-061-0/+1
| | | | | | don't fix dictionaries of size 0. setting dictEnd == source triggers prefix mode, thus removing possibility to use CDict.
* fixed frametest errorYann Collet2018-05-061-2/+6
| | | | | | | | | | | | | | | | | | | | The error can be reproduced using following command : ./frametest -v -i100000000 -s1659 -t31096808 It's actually a bug in the stream LZ4 API, when starting a new stream and providing a first chunk to complete with size < MINMATCH. In which case, the chunk becomes a dictionary. No hash was generated and stored, but the chunk is accessible as default position 0 points to dictStart, and position 0 is still within MAX_DISTANCE. Then, next attempt to read 32-bits from position 0 fails. The issue would have been mitigated by starting from index 64 KB, effectively eliminating position 0 as too far away. The proper fix is to eliminate such "dictionary" as too small. Which is what this patch does.
