6d222c437c Set requestedParams in ZSTD_initCStream*() 
The correct parameters are used once, but once `ZSTD_resetCStream()` is
called the default parameters (level 3) are used. Fix this by setting
`requestedParams` in the `ZSTD_initCStream*()` functions.

The added tests both fail before this patch and pass after.

7ca12a1455 tests: use /dev/zero instead of /dev/random on all systems except GNU/Hurd 
https://github.com/facebook/zstd/pull/1124 broke the test suite
on Linux.  Looks like GNU/Hurd is the only operating system where
/dev/random is available for writing by unprivileged processes.

https://github.com/facebook/zstd/pull/1222 reverted the change
introduced by https://github.com/facebook/zstd/pull/1124 for OpenBSD
only, other operating systems need that change to be reverted, too.

Fixes: 2dde9d5aba ("Write to /dev/random for test")
Complements: 276988f794 ("OpenBSD is unable to write to /dev/zero")

Merge pull request #1222 from bket/openbsd 
2 separate issues found when running zstd's tests on OpenBSD
 2018-06-30 11:47:41 -07:00

527dbf89ec xz/lzma warning causes test to fail 
OpenBSD's port building infrastructure is able to build in a privilege
separated mode. It uses a privilege drop model. Regression tests fail in
this mode as xz/lzma is unable to set file group and errors out with:

xz: tmp.xz: Cannot set the file group: Operation not permitted
gmake[1]: *** [Makefile:307: zstd-playTests] Error 2

Actually it is not a xz/lzma error but a warning causing zstd's
regression test to fail. Proposed fix is to have xz/lzma not set the
exit status to 2 even if a condition worth a warning was detected (-Q
flag).

276988f794 OpenBSD is unable to write to /dev/zero 
https://github.com/facebook/zstd/pull/1124 fixes an issue with GNU/Hurd
being unable to write to /dev/zero. Implemented fix is writing to
/dev/random instead.

On OpenBSD a regular user is unable to write to /dev/random because of
permissions set on this device. Result is failing a regression test.

Proposed solution should work for all platforms.
