I'm going to release gzip-1.10 this year. Any testing would be most appreciated. See the NEWS below.
gzip snapshot: https://meyering.net/gzip/gzip-ss.tar.xz 760 KB https://meyering.net/gzip/gzip-ss.tar.xz.sig https://meyering.net/gzip/gzip-1.9.15-17f5c.tar.xz Changes in gzip since v1.9: Jim Meyering (7): maint: post-release administrivia build: remove -Wformat-truncation=2 to avoid avoid false-positive maint: update gnulib to latest; also update bootstrap and init.sh build: make the autoconf-2.63 requirement explicit maint: update gnulib to latest; also update bootstrap and init.sh maint: improve a comment build: avoid build failure with --enable-gcc-warnings and latest gcc Paul Eggert (8): misc: update --version copyright gzip: port better to mingw gzip: make the output more reproducible gzip: port better to mingw again Fix some theoretical races in signal handling gzip: fix bug in signal-handling fix * gzip.c (remove_output_file): Fix typo. gzip: fix use of uninitialized memory ==================================================== NEWS: ** Changes in behavior Compressed gzip output no longer contains the current time as a timestamp when the input is not a regular file. 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.
