Please send GNU tar bug reports to -version 1.15.91 - Sergey Poznyakoff, (CVS version) +version 1.16.1 + +* New option --exclude-tag allows to specify "exclusion tag files", i.e. + files whose presence in a directory means that the directory should not + be archived. + +* The --exclude-cache option excludes directories that contain the + CACHEDIR.TAG file from being archived. Previous versions excluded + directory contents only, while the directories themselves were + still added to the archive. + +* Support for reading ustar type 'N' header logical records has been removed. + This GNU extension was generated only by very old versions of GNU 'tar'. + Unfortunately its implementation had security holes; see + . + We don't expect that any tar archives in practical use have type 'N' + records, but if you have one and you trust its contents, you can + decode it with GNU tar 1.16 or earlier. + +* Race conditions have been fixed that in some cases briefly allowed + files extracted by 'tar -x --same-owner' (or plain 'tar -x', when + running as root) to be accessed by users that they shouldn't have been. + + +version 1.16 - Sergey Poznyakoff, 2006-10-21 + +* After creating an archive, tar exits with code 1 if some files were +changed while being read. Previous versions exited with code 2 (fatal +error), and only if some files were truncated while being archived. + +* New option --mtime allows to set modification times for all archive +members during creation. + +* Bug fixes +** Avoid running off file descriptors when using multiple -C options. +** tar --index-file=FILE --file=- sent the archive to FILE, and +the listing to stderr. + + +version 1.15.91 - Sergey Poznyakoff, 2006-06-16 + +* Incompatible changes + +** Globbing + +Previous versions of GNU tar assumed shell-style globbing when +extracting from or listing an archive. For example: + + tar xf foo.tar '*.c' + +would extract all files whose names end in '.c'. This behavior +was not documented and was incompatible with traditional tar +implementations. Therefore, starting from this version, GNU tar +no longer uses globbing by default. For example, the above invocation +is now interpreted as a request to extract from the archive the file +named '*.c'. + +To treat member names as globbing patterns, use --wildcards option. +If you wish tar to mimic the behavior of versions up to 1.15.90, +add --wildcards to the value of the environment variable TAR_OPTIONS. + +The exact way in which tar interprets member names is controlled by the +following command line options: + + --wildcards use wildcards + --anchored patterns match file name start + --ignore-case ignore case + --wildcards-match-slash wildcards match `/' + +Each of these options has a '--no-' counterpart that disables its +effect (e.g. --no-wildcards). + +These options affect both the interpretation of member names from +command line and that of the exclusion patterns (given with --exclude +and --exclude-from options). The defaults are: + + 1. For member names: --no-wildcards --anchored + 2. For exclusion patterns: --wildcards --no-anchored --wildcards-match-slash + +The options can appear multiple times in the command line, thereby +changing the way command line arguments are interpreted. For example, +to use case-insensitive matching in exclude patterns and to revert to +case-sensitive matching for the rest of command line, one could write: + + tar xf foo.tar --ignore-case --exclude-from=FILE --no-ignore-case file.name + +** Short option -l is now an alias of --check-links option, which complies +with UNIX98. This ends the transition period started with version 1.14. * New features -** New incremental snapshot file format keeps information about file names +** New option --transform allows to transform file names before storing them +in the archive or member names before extracting. The option takes a +sed replace expression as its argument. For example, + + tar cf foo.tar --transform 's,^,prefix/,' + +will add 'prefix/' to all file names stored in foo.tar. + +** --strip-components option works when deleting and comparing. In previous +versions it worked only with --extract. + +** New option --show-transformed-names enables display of transformed file +or archive. It generalizes --show-stored-names option, introduced in +1.15.90. In particular, when creating an archive in verbose mode, it lists +member names as stored in the archive, i.e., with any eventual prefixes +removed and file name transformations applied. The option is useful, +for example, while comparing `tar cv' and `tar tv' outputs. + +** New incremental snapshot file format keeps information about file names as well as that about directories. +** The --checkpoint option takes an optional argument specifying the number +of records between the two successive checkpoints. Optional dot +starting the argument intructs tar to print dots instead of textual +checkpoints. + +** The --totals option can be used with any tar operation (previous versions +understood it only with --create). If an argument to this option is +given, it specifies the signal upon delivery of which the statistics +is to be printed. Both forms of this option (with and without +argument) can be given to in a single invocation of tar. + +* Bug fixes +** Detect attempts to update compressed archives. version 1.15.90 - Sergey Poznyakoff, 2006-02-19
