Yann Collet 27e883371d fixed wrong assert() condition

 2017-06-29 18:19:09 -07:00
Yann Collet a3d9926c40 compression optimization opportunity 
switch to single-pass mode directly into output buffer

Yann Collet acbef3decd ZSTD_getFrameContentSize() is promoted to "stable" status 2017-06-29 05:19:51 -07:00
Yann Collet 037466245f refactor ZSTD_check_compressionLevel_monotonicIncrease_memoryBudget() 
use less macro statements
the initial version was meant to work with STATIC_ASSERT
but since it doesn't work and needs assert()
it's possible to rewrite it using normally compiled code
which is better for compiler.

Downside : the error message is less precise.
There is a DEBUGLOG(3,) to compensate.

Yann Collet 0c9a915a28 ZSTD_estimateCStreamSize_advanced() 2017-06-26 16:02:25 -07:00
Yann Collet 31af8290d1 ZSTD_estimateCCtx_advanced() 
ZSTD_estimateCCtx() is now a "simple" function,
taking int compressionLevel as single argument.

ZSTD_estimateCCtx_advanced() takes a CParams argument,
which is both more complete and more complex to generate.

Yann Collet 6122af9cf5 --no-big-tests for msan 
msan tests require too much RAM for 2 GB VM
 2017-06-23 00:37:15 -07:00
Yann Collet cca1ed14db Merge branch 'advancedAPI2' of github.com:facebook/zstd into advancedAPI2 2017-06-23 00:13:03 -07:00
Yann Collet 32f546c763 zstreamtest : disabled multi-threading tests with --newapi --no-big-tests 
--no-big-tests is typically used in combination with qemu-user-static
qemu-user-static allocated 4 GB of RAM upfront.
On 2 GB VM, this can degenerate into a crash.
It's not a problem as long as memory is not used.
But with multi-threading enabled, memory fragmentation kicks in,
so the amoung of RAM effectively touched increases,
and can pass beyond the 2 GB limit of the VM.

In single-threaded mode, there is no such issue :
memory requirement is smaller, and remains well-located,
so very little fragmentation is expected.

This modification should make `qemu-arm-static zstreamtests --newapi --no-big-tests`
work fine on Travis CI.
