cli: warning for stdout as default output
 2019-04-21 20:20:41 -07:00

22fae16c6f ensure tests work when stdout is not the console 
ensure this case is continuously tested on travis.

Update documentation on implicit output,
invite to not rely on implicit output in scripts.

5f8ac02b77 cli: display a warning whenever default output is stdout while input != stdin 
This behavior has been preserved for compatibility with existing ecosystem.
But it's problematic, as some environment start `lz4` without identifying stdout as console by default,
leading to a change of behavior for a same line of script.

A more sensible policy would be to default to stdout only when input is stdin.

Soft change for the time being : keep the behavior, just print a warning message.
User should prefer `-c` to explicitly select `stdout`.

Also : updated tests in Makefile to explicitly select `stdout` with `-c`.

25d96f1e4d fix out-of-bound read within LZ4_decompress_fast() 
and deprecate LZ4_decompress_fast(),
with deprecation warnings enabled by default.

Note that, as a consequence of the fix,
LZ4_decompress_fast is now __slower__ than LZ4_decompress_safe().
That's because, since it doesn't know the input buffer size,
it must progress more cautiously into the input buffer
to ensure to out-of-bound read.

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().

474c17cdc4 unified limitedOutput_directive 
between lz4.c and lz4hc.c .
was left in a strange state after the "amalgamation" patch.

Now only 3 directives remain,
same name across both implementations,
single definition place.

Might allow some light simplification due to reduced nb of states possible.

1f4a412646 decompress*_fast() function do not generate deprecation warnings 
they are classified as deprecated in the API documentation (lz4.h)
but do not yet trigger a warning,
to give time to existing applications to move away.

Also, the _fast() variants are still ~5% faster than the _safe() ones
after Dave's patch.

481a37fe47 fixed lz4frame with linked blocks 
when one block was not compressible,
it would tag the context as `dirty`,
resulting in compression automatically bailing out of all future blocks,
making the rest of the frame uncompressible.
