| Changes in version 1.12: | | Changes in version 1.13: |
| | |
|
| The value of the version test macro 'LZ_API_VERSION' is now defined as | | The variables AR and ARFLAGS can now be set from configure. (Before you |
| 1000 * major + minor. For version 1.12 it is 1012. | | needed to run 'make AR=<ar_command>'. (Reported by Hoël Bézier). |
| This change does not affect the soversion. | | |
| | |
|
| The new function 'LZ_api_version', which returns the LZ_API_VERSION of the | | In case of error in a numerical argument to a command line option, minilzip |
| library object code being used, has been added to lzlib. | | now shows the name of the option and the range of valid values. |
| | |
|
| If end of file is found at member trailer or EOS marker, | | 'minilzip --check-lib' now checks that LZ_API_VERSION and LZ_version_string |
| 'LZ_decompress_errno' now returns 'LZ_unexpected_eof' instead of | | match. |
| 'LZ_data_error'. | | |
| | |
|
| Decompression speed has been slightly increased. | | Several descriptions have been improved in manual, '--help', and man page. |
| | |
|
| A bug has been fixed in minilzip that falsely reported a library stall when | | The texinfo category of the manual has been changed from 'Data Compression' |
| decompressing a file with empty members. | | to 'Compression' to match that of gzip. (Reported by Alfred M. Szmidt). |
| | | |
| The new option '--check-lib', which compares the version of lzlib used to | | |
| compile minilzip with the version actually being used, has been added to | | |
| minilzip. | | |
| | |
| Minilzip now reports an error if a file name is empty (minilzip -t ""). | | |
| | |
| Option '-o, --output' now behaves like '-c, --stdout', but sending the | | |
| output unconditionally to a file instead of to standard output. See the new | | |
| description of '-o' in the manual. This change is not backwards compatible. | | |
| Therefore commands like: | | |
| minilzip -o foo.lz - bar < foo | | |
| must now be split into: | | |
| minilzip -o foo.lz - < foo | | |
| minilzip bar | | |
| or rewritten as: | | |
| minilzip - bar < foo > foo.lz | | |
| | |
| When using '-c' or '-o', minilzip now checks whether the output is a | | |
| terminal only once. | | |
| | |
| Minilzip now does not even open the output file if the input file is a terminal. | | |
| | |
| The words 'decompressed' and 'compressed' have been replaced with the | | |
| shorter 'out' and 'in' in the verbose output of minilzip when decompressing | | |
| or testing. | | |
| | |
| It has been documented in the manual that 'LZ_(de)compress_close' and | | |
| 'LZ_(de)compress_errno' can be called with a null argument. | | |
| | |
| It has been documented in the manual that the LZMA marker '3' ("Sync Flush" | | |
| marker) is not allowed in lzip files. Marker '3' is a device for interactive | | |
| communication between applications using lzlib, but is useless and wasteful | | |
| in a file, and is excluded from the media type 'application/lzip'. The LZMA | | |
| marker '2' ("End Of Stream" marker) is the only marker allowed in lzip | | |
| files. | | |
| | |
| It has been documented in the manual that not calling 'LZ_decompress_finish' | | |
| prevents lzlib from detecting a truncated member. | | |
| | |
| It has been documented in the manual that 'LZ_decompress_read' returns at | | |
| least once per member so that 'LZ_decompress_member_finished' can be called | | |
| (and trailer data retrieved) for each member, even for empty members. | | |
| Therefore, 'LZ_decompress_read' returning 0 does not mean that the end of | | |
| the stream has been reached. | | |
| | |
| It has been documented in the manual that 'LZ_(de)compress_read' can be | | |
| called with a null buffer pointer argument. | | |
| | |
| Real code examples for the most common uses of the library have been added | | |
| to the tutorial. | | |
| | |
| 'bbexample.c' has been simplified to not use 'LZ_(de)compress_write_size'. | | |
| | |
| 'lzcheck' now accepts options '-s' (to check LZ_compress_sync_flush) and | | |
| '-m' (to check member by member decompression). | | |
| | |
| 'lzcheck.c' now also tests member by member decompression without | | |
| intermediate calls to 'LZ_decompress_finish'. | | |
| | |
| The new file 'ffexample.c', containing example functions for file-to-file | | |
| compression/decompression, has been added to the distribution. | | |
| | |
| The commands needed to extract files from a tar.lz archive have been | | |
| documented in the output of 'minilzip --help' and in the man page. | | |
| | |
| 'make install-bin' no longer installs the minilzip man page. This is to | | |
| prevent 'make install-bin install-man-compress' from installing the man page | | |
| twice before compressing it. | | |
| | |
| The new targets 'install-bin-compress' and 'install-bin-strip-compress', | | |
| which install a (stripped) minilzip and a compressed man page, have been | | |
| added to the Makefile. | | |
| | |
| 9 new test files have been added to the testsuite. | | |
