This matches GNU gzip and it + is more logical as at that point the output file has + already been successfully closed. + + - Fix handling of .xz files with an unsupported check type. + Previously such printed a warning message but then xz + behaved as if an error had occurred (didn't decompress, + exit status 1). Now a warning is printed, decompression + is done anyway, and exit status is 2. This used to work + slightly before 5.0.0. In practice this bug matters only + if xz has been built with some check types disabled. As + instructed in PACKAGERS, such builds should be done in + special situations only. + + - Fix "xz -dc --single-stream tests/files/good-0-empty.xz" + which failed with "Internal error (bug)". That is, + --single-stream was broken if the first .xz stream in + the input file didn't contain any uncompressed data. + + - Fix displaying file sizes in the progress indicator when + working in passthru mode and there are multiple input files. + Just like "gzip -cdf", "xz -cdf" works like "cat" when the + input file isn't a supported compressed file format. In + this case the file size counters weren't reset between + files so with multiple input files the progress indicator + displayed an incorrect (too large) value. + + * liblzma: + + - API docs in lzma/container.h: + * Update the list of decoder flags in the decoder + function docs. + * Explain LZMA_CONCATENATED behavior with .lzma files + in lzma_auto_decoder() docs. + + - OpenBSD: Use HW_NCPUONLINE to detect the number of + available hardware threads in lzma_physmem(). + + - Fix use of wrong macro to detect x86 SSE2 support. + __SSE2_MATH__ was used with GCC/Clang but the correct + one is __SSE2__. The first one means that SSE2 is used + for floating point math which is irrelevant here. + The affected SSE2 code isn't used on x86-64 so this affects + only 32-bit x86 builds that use -msse2 without -mfpmath=sse + (there is no runtime detection for SSE2). It improves LZMA + compression speed (not decompression). + + - Fix the build with Intel C compiler 2021 (ICC, not ICX) + on Linux. It defines __GNUC__ to 10 but doesn't support + the __symver__ attribute introduced in GCC 10. + + * Scripts: Ignore warnings from xz by using --quiet --no-warn. + This is needed if the input .xz files use an unsupported + check type. + + * Translations: + + - Updated Croatian and Turkish translations. + + - One new translations wasn't included because it needed + technical fixes. It will be in upcoming 5.4.0. No new + translations will be added to the 5.2.x branch anymore. + + - Renamed the French man page translation file from + fr_FR.po to fr.po and thus also its install directory + (like /usr/share/man/fr_FR -> .../fr). + + - Man page translations for upcoming 5.4.0 are now handled + in the Translation Project. + + * Update doc/faq.txt a little so it's less out-of-date. + + 5.2.7 (2022-09-30) * liblzma: |
