The copy_string_unquote function does not handle arguments which only
consist of a single quote. A string is only quoted if two quoting
characters exist.
How to reproduce:
tar --checkpoint-action exec=\"
* src/checkpoint.c (checkpoint_finish_compile): Set default action,
if necessary.
* tests/checkpoint/defaults.at: New testcase.
* tests/checkpoint/dot-compat.at: New testcase.
* tests/checkpoint/dot-int.at: New testcase.
* tests/checkpoint/dot.at: New testcase.
* tests/checkpoint/interval.at: New testcase.
* tests/Makefile.am: Add new testcases.
* tests/testsuite.at Include new testcases.
This action instructs tar to pause until given signal is delivered.
The newer genfile tool uses this action for communication between
genfile and tar in exec mode. This eliminates race conitions and
speeds up the tests based on exec mode.
* doc/tar.texi: Document changes.
* paxutils: Upgrade.
* src/checkpoint.c: Implement the wait action.
* src/common.h (decode_signal): New proto.
* src/tar.c (decode_signal): New function.
(set_stat_signal): Rewrite.
* tests/dirrem01.at: Adjust genfile and tar command line arguments
to use the new feature.
* tests/dirrem02.at: Likewise.
* tests/filerem01.at: Likewise.
* tests/filerem02.at: Likewise.
* tests/grow.at: Likewise.
* tests/sptrcreat.at: Likewise.
* tests/sptrdiff00.at: Likewise.
* tests/sptrdiff01.at: Likewise.
* tests/truncate.at: Likewise.
* src/checkpoint.c (getwidth, format_checkpoint_string):
Use long and strtol, not int, to avoid overflow issues.
(getwidth): Don't assume termios.h defines TIOCGWINSZ,
as it doesn't on some older hosts.
* NEWS: Update.
* doc/tar.texi: Update.
* src/buffer.c (print_stats): Avoid use of additional string buffer.
Allow for text to be NULL.
Call gettext if it is not.
(format_total_stats): Don't use gettext when calling print_stats.
* src/checkpoint.c (def_format): Change default format.
(format_checkpoint_string): Implement optional arguments for
T conversion.
(finish_checkpoint_actions): Rename to checkpoint_flush_actions,
make extern. All uses changed.
* src/common.h (checkpoint_flush_actions): New proto.
* src/tar.c (main): Set error_hook
* src/buffer.c (format_total_stats): The format arg is const
All uses updated.
(default_total_format): const
* src/checkpoint.c (tty, tty_cleanup): New static.
(format_checkpoint_string): New "canned" format %c
(checkpoint_finish): New function.
* src/common.h (checkpoint_finish): New proto.
* src/tar.c (main): Call checkpoint_finish.`
* NEWS: Update.
* configure.ac: Version 1.27.90
* gnulib.modules: Add fprintftime.
* doc/tar.texi: Document the "totals" action and new format specifiers
for echo and ttyout checkpoint actions.
* src/buffer.c (compute_duration): Return computed value.
(print_stats): Don't print trailing newline. Return number of
characters output.
(format_total_stats): New function.
(print_total_stats): Rewrite via format_total_stats.
* src/checkpoint.c (checkpoint_opcode) <cop_totals>: New opcode.
(checkpoint_compile_action): Handle cop_totals.
(expand_checkpoint_string): Remove.
(format_checkpoint_string): New function to be used instead of
expand_checkpoint_string. All callers updated.
* src/common.h (TF_READ,TF_WRITE)
(TF_DELETED): New constants.
(format_total_stats,print_total_stats): New protos.
This lint was found by GCC 4.6.2 on Fedora 15 x86-64.
* src/buffer.c (buffer_write_global_xheader, mv_end, set_start_time)
(compute_duration, print_total_stats, flush_read, flush_write):
* src/checkpoint.c (checkpoint_finish_compile):
* src/list.c (test_archive_label):
* src/misc.c (chdir_count):
* src/names.c (const):
* src/unlink.c (finish_deferred_unlinks):
Define with (void) instead of with (), for slightly-better C type
checking and to avoid a GCC warning.
* src/compare.c (diff_dumpdir):
* src/tar.c (parse_owner_group): Remove unused local.
* src/misc.c (chdir_do):
* src/tar.c (add_exclude_array): Rename local to avoid shadowing.
(LOW_DENSITY_NUM, MID_DENSITY_NUM, HIGH_DENSITY_NUM):
Define only if needed.
* src/update.c (update_archive): Initialize a local; this fixes
what appears to be a real bug.
