0d4a974639 Merge branch 'dev' into fixframe 2019-04-15 11:18:33 -07:00

ac5d2629c1 added a fake initialization to please an analyzer 
which is unable to understand that the variable is necessarily initialized
in spite of an assert just before.

ce0f316989 fix fuzzer tests on dirty context 
context is no longer dirty after a failed compressed block.
Actually, all indexes are fine.
It remains compatible with continued streaming, and reset*_fast().

3ab916c6a2 frametest: removed uninitialized warning 
was a false positive, but better remove it anyway

ensure canary remains within buffer limits

c222dd9010 fixed frametest 
One test could write a canary value out of bound
in exceptional conditions involving multiple flushes
triggered by -s3421 -t462948.

20c2a5fc94 added command -BI for "Independent Blocks" 
This is the reverse of `-BD`, and the current default.

This command can be useful to reverse a previous `-BD` command.
It may in the future be more important
if `lz4` switches to generating dependent blocks by default.

d8d5f14138 fixed loadDictHC 
by making a full initialization
instead of a fast reset.

14c71dfa9c modified LZ4_initStreamHC() to look like LZ4_initStream() 
it is now a pure initializer, for statically allocated states.
It can initialize any memory area, and because of this, requires size.

2ece0d8380 created LZ4_initStream() 
- promoted LZ4_resetStream_fast() to stable
- moved LZ4_resetStream() into deprecate, but without triggering a compiler warning
- update all sources to no longer rely on LZ4_resetStream()

note : LZ4_initStream() proposal is slightly different :
it's able to initialize any buffer, provided that it's large enough.
To this end, it accepts a void*, and returns an LZ4_stream_t*.

c491df54ec created LZ4_initStreamHC() 
- promoted LZ4_resetStreamHC_fast() to stable
- moved LZ4_resetStreamHC() to deprecated (but do not generate a warning yet)
- Updated doc, to highlight difference between init and reset
- switched all invocations of LZ4_resetStreamHC() onto LZ4_initStreamHC()
- misc: ensure `make all` also builds /tests

the test fails, as intended,
since #631 is not merged yet in this branch.

Merge pull request #592 from lz4/compressEnd 
fix LZ4F_compressEnd()
 2018-10-09 15:37:55 -07:00
Yann Collet
e07a37d712 added a test for LZ4F_compressEnd() 
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.
