Lasse Collin	9595a3119b	liblzma: Add optional autodetection of LZMA end marker. Turns out that this is needed for .lzma files as the spec in LZMA SDK says that end marker may be present even if the size is stored in the header. Such files are rare but exist in the real world. The code in liblzma is so old that the spec didn't exist in LZMA SDK back then and I had understood that such files weren't possible (the lzma tool in LZMA SDK didn't create such files). This modifies the internal API so that LZMA decoder can be told if EOPM is allowed even when the uncompressed size is known. It's allowed with .lzma and not with other uses. Thanks to Karl Beldan for reporting the problem.	2022-07-13 22:24:07 +03:00
Lasse Collin	d267d109c3	liblzma: Rename EROFS LZMA to MicroLZMA. It still exists primarily for EROFS but MicroLZMA is a more generic name (that hopefully doesn't clash with something that already exists).	2021-09-05 20:38:12 +03:00

liblzma: Add optional autodetection of LZMA end marker.

Turns out that this is needed for .lzma files as the spec in
LZMA SDK says that end marker may be present even if the size
is stored in the header. Such files are rare but exist in the
real world. The code in liblzma is so old that the spec didn't
exist in LZMA SDK back then and I had understood that such
files weren't possible (the lzma tool in LZMA SDK didn't
create such files).

This modifies the internal API so that LZMA decoder can be told
if EOPM is allowed even when the uncompressed size is known.
It's allowed with .lzma and not with other uses.

Thanks to Karl Beldan for reporting the problem.

liblzma: Rename EROFS LZMA to MicroLZMA.

It still exists primarily for EROFS but MicroLZMA is
a more generic name (that hopefully doesn't clash with
something that already exists).
