Yann Collet beb9b4b398 fixed ZSTDMT_initCStream() when contentSizeFlag==1 by default
and a wrong test in zstreamtest --mt
2017-10-13 19:09:30 -07:00
Yann Collet 213ef3b510 fixed ZSTD_initCStream_advanced() behavior, which depends on contentSizeFlag,
and a stream fuzzer test, which was incorrect
(relied on 0 being unconditionnally transformed into `ZSTD_CONTENTSIZE_UNKNOWN`)
2017-10-13 19:01:58 -07:00
Yann Collet 3c1e3f8ec9 contentSizeFlag enabled by default would also fail for streaming and MT operations
fixed

Yann Collet e0065cf660 make test : removed zstreamtest unit tests for variants
slightly reduced time to create dictionary
at beginning of unit tests
2017-09-28 18:34:38 -07:00
Yann Collet 47c6a95d07 zstreamtest : run unit tests only during "normal" session
not during --mt, --newapi and --opaque
this avoids running them 4x during `make test`

Yann Collet d6770f80af minor : rewrite unit tests using CHECK_Z macro 2017-09-28 02:14:48 -07:00
Yann Collet 9fe50ed623 fixed maximum windowLog for zstreamtest --newapi
for compatibility with low memory VM
2017-09-28 01:42:06 -07:00
Yann Collet 9b5b47ac93 ensure adjustCParams adjust hLog and cLog even without srcSize
It would previously exit when srcSize is unknown.
But in the case of custom parameters,
hLog and cLog can still be too large in comparison with windowLog.

Reduces maximum memory allocated during zstreamtest --newapi
2017-09-28 01:25:40 -07:00
Yann Collet aa800c4793 reduced memory usage of zstreamtest --newapi
to run on memory-constrained VM
2017-09-27 18:00:15 -07:00
Yann Collet bc32b40b98 reduced zstreamtest --mt memory load
adjust compression level, hence memory usage, depending on nb threads
in order to run correctly on memory-starved VM.

Yann Collet bfabd1d4dc fixed zstreamtest decoding error
same error (wrong output buffer size) was present
on --mt and --new_api tests.
2017-09-27 01:01:11 -07:00
Yann Collet ca306c1c84 fixed a bug in zstreamtest
decoder output buffer would receive a wrong size.

In previous version, ZSTD_decompressStream() would blindly trust the caller that pos <= size.
In this version, this condition is actively checked,
and the function returns an error code if this condition is not respected.

This check could also be done with an assert(),
but since this is a user-facing interface, it seems better to keep this check at runtime.

Nick Terrell c233bdbaee Increase maximum window size
* Maximum window size in 32-bit mode is 1GB, since allocations for 2GB fail
  on my Mac.
* Maximum window size in 64-bit mode is 2GB, since that is the largest
  power of 2 that works with the overflow prevention.
* Allow `--long=windowLog` to set the window log, along with
  `--zstd=wlog=#`. These options also set the window size during
  decompression, but don't override `--memory=#` if it is set.
* Present a helpful error message when the window size is too large during
  decompression.
* The long range matcher defaults to a hash log 7 less than the window log,
  which keeps it at 20 for window log 27.
* Keep the default long range matcher window size and the default maximum
  window size at 27 for the API and CLI.
* Add tests that use the maximum window size and hash size for compression
  and decompression.

Yann Collet 96f0cde31a minor function rename
ZSTD_estimateCStreamSize_advanced_usingCParams -> ZSTD_estimateCStreamSize_usingCParams
_usingX is clear.
_advanced feels redundant
