afda7ca4e2 Add a simple 'check' target to ensure basic functionality 
Mainly checking that pxz(1) can compress and that it's output can be
extracted by xz(1).

f7e3150751 CVE-2015-1200: Race condition in setting permissions on output file 
Race condition in pxz 4.999.99 Beta 3 uses weak file permissions
for the output file when compressing a file before changing the
permission to match the original file, which allows local users
to bypass the intended access restrictions.

Patch by Moritz Mühlenhoff <jmm@inutil.org>

e043807e7b Fix memory leak 
When many files are specified on the command line, a lot of memory
is leaked.  Free the space which is being leaked.

1f81723b74 _SC_ARG_MAX cannot always be mallocated, so try smaller values instead. In fact, we do not always need this memory mostly. 2015-01-19 14:53:04 +01:00

at the same time.

1a4bde7dee use lzma_stream_encoder() in stead of lzma_easy_encoder() so that we can 
get the appropriate dictionary size regardless of preset level and also
allow for compression options etc. as well :)
