Changes in version 1.8:
|
|
|
|
A buffer overflow has been fixed in zcat which happened sometimes when
|
|
the '-v, --show-nonprinting' option was used (or indirectly enabled).
|
|
A canary byte has been added to the output buffer to prevent the buffer
|
|
overflow from happening again.
|
|
|
|
The option '-R, --dereference-recursive', which recursively follows
|
|
symbolic links, has been added to zcat, zgrep, ztest and zupdate.
|
|
|
|
The option '-r, --recursive' now skips symlinks that are encountered
|
|
recursively.
|
|
|
|
If no files are given to zcat, zgrep, ztest and zupdate, a recursive
|
|
search will now examine the current working directory.
|
|
|
|
Recursive directory loops are now detected.
|
|
|
|
zcat and zgrep now ignore directories given in the command line if
|
|
'--recursive' is not specified, instead of reporting an error.
|
|
|
|
Extra trailing slashes are now removed from directories given in the
|
|
command line before recursing into them.
|
|
|
|
zcat and zgrep now show the right error when they can't open an input
|
|
file instead of showing "No such file or directory".
|
|
|
|
Killed decompressors are now waited for, preventing failure caused by
|
|
too many open pipes.
|
|
|
|
Test and document that if a file fails to decompress, zcat, zgrep and
|
|
ztest continue processing the rest of the files.
|
|
|
|
Test and document that if an error happens while recompressing a file,
|
|
zupdate exits immediately without recompressing the rest of the files.
|
|
|
|
The configure script now accepts appending options to CXXFLAGS using the
|
|
syntax 'CXXFLAGS+=OPTIONS'.
