+ * src/create.c (dump_file0): The conditional at line
+ 1296 prevented incremental backups on individual files
+ from working, as reported by Andreas Schuldei
+ <andreas@schuldei.org>.
+
+ This is due to the condition
+
+ (0 < top_level || !incremental_option)
+
+ Removing it makes incremental backups work for individual
+ files as well as for directories. On the other hand, it does
+ not affect other functionality, as shown by the reasoning below:
+
+ To begin with, the two parts of this condition are mutually
+ superfluous, because
+
+ 1) when top_level < 0, incremental_option == 1
+ so the condition yields false
+ 2) when top_level >= 0, incremental_option == 0
+ so the condition yields true.
+
+ In other words, it is completely equivalent to
+
+ (!incremental_option)
+
+ Now, let's consider the effect of its removal. There are two cases:
+
+ 1) when incremental_option==1
+ This means incremental backup in progress. In this case dump_file
+ is invoked only for directories or for files marked with 'Y' by
+ get_directory_contents. The latter are those that did not meet the
+ condition in incremen.c:242, which is exactly the same condition
+ as this at create.c:1296. So, for these files the check
+ (!incremental_option) is useless, since the rest of the
+ conditional will yield false anyway. On the other hand, if
+ dump_file is invoked on a directory, the conditional will yield
+ false due to !S_ISDIR assertion, so these will be processed as usual.
+
+ Thus, for this case the extra condition (!incremental_option) is
+ irrelevant, and its removal won't alter the behavior of tar,
+ *except* that it will enable incremental backups on individual
+ files, which is the wanted effect.
+
+ 2) when incremental_option==0
+ In this case the condition yields true and its removal does not
+ affect the functionality.

+ * THANKS: Updated
+ * configure.ac: Raised patchlevel to 92a
+ * src/incremen.c: Minor stylistic fixes.
+ * tests/listed01.sh: New test. Check listed incremental
+ backups on individual files.
+ * tests/Makefile.am: Added listed01.sh

+
+ * src/common.h (simple_finish_header,start_private_header): New
+ declarations
+ (xheader_ghdr_name): Changed declaration
+ * src/create.c (start_private_header): Removed static qualifier.
+ (write_extended): Removed superfluous last argument. Use
+ xheader_write()
+ (simple_finish_header): New function.
+ (finish_header): Use simple_finish_header() to break recursive
+ dependency between this function and write_extended().
+ * src/tar.c (assert_format): Do not bail out if several
+ --format arguments are given. This is a common case when
+ TAR_OPTIONS are used.
+ (decode_options): New option --show-defaults displays the
+ compiled-in defaults.
+ Use POSIX format if no --format option was given and
+ --pax-option was specified.
+ Do not allow to use --pax-option unless the archive format is
+ set to POSIX (or reading subcommand is requested).
+
+ * src/update.c (update_archive): Write global extended header if
+ constructed.
+ * src/xheader.c (xheader_format_name): Bugfix.
+ (xheader_xhdr_name): Changed the default extended header name
+ to '%d/PaxHeaders.%p/%f', as POSIX requires.
+ (xheader_ghdr_name): Removed unused argument.
+ (xheader_write,xheader_write_global): New function.
+ (xheader_decode): Modified to honor overrides whatever
+ the current archive format is.
+
+ * src/delete.c (delete_archive_members): Call xheader_decode
+ unconditionally.
+ * src/list.c (decode_header): Likewise.
+ * src/incremen.c (sort_obstack): Fixed typo in the comment
+
+ * doc/tar.texi: Document new default for extended
+ header names.
+
+ * tests/before: Accept an optional list of allowed archive
+ formats. Exit with the status 77 if the current archive
+ format does not match any of them.
+ * tests/delete03.sh: Require gnu, oldgnu or posix format
+ * tests/incremen.sh: Require gnu or oldgnu format
+ * tests/multiv01.sh: Likewise
