+.xz and .lzma Test Files
+------------------------
0. Introduction
- This directory contains bunch of files to test handling of .xz files
- in .xz decoder implementations. Many of the files have been created
- by hand with a hex editor, thus there is no better "source code" than
- the files themselves. All the test files (*.xz) and this README have
- been put into the public domain.

1. File Types
- Good files (good-*.xz) must decode successfully without requiring
- a lot of CPU time or RAM.

Unsupported files (unsupported-*.xz) are good files, but headers
indicate features not supported by the current file format
specification.
- Bad files (bad-*.xz) must cause the decoder to give an error. Like
- with the good files, these files must not require a lot of CPU time
- or RAM before they get detected to be broken.

Uncompressed Size bytes of output will have been produced but
the LZMA2 decoder doesn't indicate end of stream.
+
+3. Descriptions of Individual .lzma Files
+
+3.1. Good Files
+
+ good-unknown_size-with_eopm.lzma has unknown size in the header
+ and end of payload marker at the end.
+
+ good-known_size-without_eopm.lzma has a known size in the header
+ and no end of payload marker at the end.
+
+ good-known_size-with_eopm.lzma has a known size in the header
+ and end of payload marker at the end. XZ Utils 5.2.5 and older
+ will give an error at the end of the file after producing the
+ correct uncompressed output.
+
+
+3.2. Bad Files
+
+ bad-unknown_size-without_eopm.lzma has unknown size in the header
+ but no end of payload marker at the end. This file might be seen
+ by a decoder as if it were truncated.
+
+ bad-too_big_size-with_eopm.lzma has too big uncompressed size in
+ the header and the end of payload marker will be detected before
+ the specified number of bytes have been decoded.
+
+ bad-too_small_size-without_eopm-1.lzma has too small uncompressed
+ size in the header. The decoder will look for end of payload marker
+ but instead find a literal that would produce more output.
+
+ bad-too_small_size-without_eopm-2.lzma is like -1 above but instead
+ of a literal the problem occurs with a short repeated match.
+
+ bad-too_small_size-without_eopm-3.lzma is like -1 above but instead
+ of a literal the problem occurs in the middle of a match.
