 2018-01-11 11:40:07 -08:00
Yann Collet 752bae4a48 added warning message 
when pathological dataset is detected
(note : cover_optimize needs -v to display the warning)
 2018-01-11 11:29:28 -08:00

Pathological samples may result in literal section being incompressible.
This case is now detected,
and literal distribution is replaced by one that can be written into the dictionary.

Yann Collet ff795580f2 fixed bug #976, reported by @indygreg 
constants in zstd.h should not depend on MIN() macro which existence is not guaranteed.

Added a test to check the specific constants.
The test is a bit too specific.
But I have found no way to control a more generic "are all macro already defined" condition,
especially as this is a valid construction (the missing macro might be defined later, intentionnally).

Yann Collet 292eeb672f api doc : grouped all ZSTD_create*_advanced() functions together 
in a new "custom memory allocator" paragraph
which is itself part of "memory management" category.

This makes it simpler to see the relation between the type and its usages.

This fixes the following crash:
