@@ -1,30 +1,92 @@ -Changes in version 1.11: +Changes in version 1.12: -In case of decompression error caused by corrupt or truncated data, -LZ_decompress_read now does not signal the error immediately to the -application, but waits until all decoded bytes have been read. This -allows tools like tarlz to recover as much data as possible from damaged -members. +The value of the version test macro 'LZ_API_VERSION' is now defined as +1000 * major + minor. For version 1.12 it is 1012. +This change does not affect the soversion. -It is now an error to specify two different operations to minilzip in -the command line (--decompress and --test). +The new function 'LZ_api_version', which returns the LZ_API_VERSION of the +library object code being used, has been added to lzlib. -Minilzip now also checks for errors when closing the input file. +If end of file is found at member trailer or EOS marker, +'LZ_decompress_errno' now returns 'LZ_unexpected_eof' instead of +'LZ_data_error'. -Minilzip now compiles on DOS with DJGPP. (Patch from Robert Riebisch). +Decompression speed has been slightly increased. -The descriptions of '-0..-9', '-m' and '-s' in the manual have been -improved. +A bug has been fixed in minilzip that falsely reported a library stall when +decompressing a file with empty members. -It has been documented that it is safe to call 'LZ_(de)compress_finish' -as many times as needed. Examples in the manual have been simplified. +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. -The configure script now accepts appending options to CFLAGS using the -syntax 'CFLAGS+=OPTIONS'. +Minilzip now reports an error if a file name is empty (minilzip -t ""). -Makefile targets 'install-bin*' have been renamed to 'install-lib*'. New -'install-bin*' targets have been created that install a shared minilzip, -or a static minilzip if the shared library has not been configured. +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 -It has been documented in INSTALL the use of -CFLAGS+='-D __USE_MINGW_ANSI_STDIO' when compiling on MinGW. +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. |
