(flush_read): Bugfix: the condition at line 714 included
|| (status > 0 && !read_full_records_option)
which is grossly wrong, since even if new_volume() below succeeds,
the subsequent call to rmtread will overwrite the chunk of data
already read in the buffer and thus spoil everything.
Use keywords from the global headers.
Correctly handle UTF-8 conversions.
(xheader_list_destroy): New function.
(xheader_set_single_keyword,xheader_set_keyword_equal): Added
missing gettext markers
(decode_record): Rewritten using caller-provided handler and
data closure.
(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.
(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.
(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).
(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().
(new_volume,check_label_pattern): Changed return type.
(time_to_start_writing): Changed data type
(file_to_switch_to): Removed. Variable never assigned to.
(open_archive) Moved option compatibility checks to tar.c
