[ANNOUNCEMENT] Updated: gzip 1.13
The following package has been upgraded in the Cygwin distribution: * gzip 1.13 GNU gzip is a popular data compression program, developed to replace compress because of patents covering the LZW algorithm at the time, with better compression as a bonus.

This is more useful with programs like 'less' that treat gzip exit status 2 as a non-failure. Bug fixes - 'gzip -d' no longer fails to report invalid compressed data that uses a dictionary distance outside the input window.

[ANNOUNCEMENT] Updated: gzip 1.12

Previously, 'gzip -l' output the 32-bit value stored in the gzip header even though that is the uncompressed length modulo 2**32. Now, 'gzip -l' calculates the uncompressed length by decompressing the data and counting the resulting bytes. Although this can take much more time, nowadays the correctness pros seem to outweigh the performance cons. 'zless' is no longer installed on platforms lacking 'less'. * Bug fixes zgrep applied to a crafted file name with two or more newlines can no longer overwrite an arbitrary, attacker-selected file. [bug introduced in gzip-1.3.10] zgrep now names input file on error instead of mislabeling it as "(standard input)", if grep supports the GNU -H and --label options. 'zdiff -C 5' no longer misbehaves by treating '5' as a file name.

Instead, the output contains a null (zero) timestamp. This makes gzip's behavior more reproducible when used as part of a pipeline. (As a reminder, even regular files will use null timestamps after the year 2106, due to a limitation in the gzip format.) * Bug fixes A use of uninitialized memory on some malformed inputs has been fixed. [bug present since the beginning] A few theoretical race conditions in signal handers have been fixed. These bugs most likely do not happen on practical platforms. [bugs present since the beginning] Noteworthy changes in release 1.9 (2018-01-07) [stable] * Bug fixes gzip -d -S SUFFIX file.SUFFIX would fail for any upper-case byte in SUFFIX. E.g., before, this command would fail: $ :|gzip > kT && gzip -d -S T kT gzip: kT: unknown suffix -- ignored [bug present since the beginning] When decompressing data in 'pack' format, gzip no longer mishandles leading zeros in the end-of-block code. [bug introduced in gzip-1.6] When converting from system-dependent time_t format to the 32-bit unsigned MTIME format used in gzip files, if a timestamp does not fit gzip now substitutes zero instead of the timestamp's low-order 32 bits, as per Internet RFC 1952. When converting from MTIME to time_t format, if a timestamp does not fit gzip now warns and substitutes the nearest in-range value instead of crashing or silently substituting an implementation-defined value (typically, the timestamp's low-order bits). This affects timestamps before 1970 and after 2106, and timestamps after 2038 on platforms with 32-bit signed time_t. [bug present since the beginning] Commands implemented via shell scripts are now more consistent about failure status. For example, 'gunzip --help >/dev/full' now consistently exits with status 1 (error), instead of with status 2 (warning) on some platforms. [bug present since the beginning] Support for VMS and Amiga has been removed. It was not working anyway, and it reportedly caused file name glitches on MS-Windowsish platforms. -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation:https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
