8 The test suite is too incomplete.
10 If the memor usage limit is less than about 13 MiB, xz is unable to
11 automatically scale down the compression settings enough even though
12 it would be possible by switching from BT2/BT3/BT4 match finder to
15 The code to detect number of CPU cores doesn't count hyperthreading
16 as multiple cores. In context of xz, it probably should.
17 Hyperthreading is good at least with p7zip.
25 xz could create sparse files when decompressing. (Some prototyping
28 xz doesn't support copying extended attributes, access control
29 lists etc. from source to target file.
31 Multithreaded compression
33 Multithreaded decompression
35 Buffer-to-buffer coding could use less RAM (especially when
36 decompressing LZMA1 or LZMA2).
38 I/O library is not implemented. It will possibly be named libzzf.
44 Some tutorial is needed for liblzma. I have planned to write some
45 extremely well commented example programs, which would work as
46 a tutorial. I suppose the Doxygen tags are quite OK as a quick
47 reference once one is familiar with the liblzma API.
49 Document the LZMA1 and LZMA2 algorithms.
