Linux systems, when we build as a tool we think we have lutimes but it
doesn't work on some filesystems at runtime. A bit ugly but effective
and without use of AC_TRY_RUN in the tool build. Tidier (than mine)
set_ftime reorganization from christos.
- This is explained in a comment in pat_rep.c inside mod_name(). I did not
want to change the default behavior, so I added another modifier "s" which
when set, the pattern will not modify the symlink destination.
- While here I fixed another bug that was introduced before by the fix in
PR/35257 where the renaming was happening twice since we called rep_name
twice.
- Finally if we are renaming hard of soft-link targets print the renames for
those too.
There are a lot of tty_warn(0,...) and syswarn(0,...) which probably ought
to be tty_warn/syswarn(1,...) to force an error exit. However some are
used in interactive parts (eg opening a continuation archive) where there
is a separate retry loop.
So we just pass a failure code out to main() - how quaint!
This should now cause the NetBSD build to fail when gzip tries to write
to a non-existant directory.
(I suspect there are still many errors that don't get reported correctly.)
PR/18840: Frederick Bruckman: Fix for PR/18663 incomplete pax symlink handling
This patch makes ``--insecure'' do something. Now if ``--insecure''
is not set (the default) we do a realpath(3) in all the pathnames
that we are trying to create and if either realpath fails, or the
path is outside our working directory, we print a warning and die.
This maybe too strict and might fail on valid archives that create
symlinks and directories in the wrong order.
an extract. With -h this will cause existing absolute symlinks to be treated
as relative to the current directory.
Helps sysinst handle existing symlinks in the target system.
Remove 'L' from the usage (got spilt into 'h' and 'H' many moons ago)
Add 'S' to usage, and put into correct place in options list.
we can append to it. Modify the code so that file_write is re-entrant,
even in the gnu long name/link hack.
The old code assumed that the buffer already contained the necessary
blocks to satisfy the read file request that contained the long
filename. This is not always the case, specially when we are dealing
with pipes which do shorter reads, thus having more probability
that a long file name will fall across a buffer boundary.
To reproduce, create a tar archive with a lot of gnu-long-names
(pkgsrc/devel/libsigc++2 is a good example), do a tar -tf to get
a list of filenames, compress it and do a tar -tzf to get another
list of the filenames. Notice that the two lists differ.
extract. We now generate GNU tar archives by default ("ustar ^@" instead of
"ustar^@00"). GNU extensions can be disabled with --strict.
XXX: long symlinks untested.
- correct -C processing
- add ability to read filenames and flags from a file
- don't print dangerous escape sequences to the terminal
- use strlcpy/strncpy properly.
- handle tmpfile creation better.
- improve documentation of options.
- handle stdout/stderr list selection correctly.
- kill gzip when we get interrupted.
- simplify gzip setup.
- add more flags to programs.
additional changes:
- librmt processing.
- set POSIXLY_CORRECT in options parsing.
- prevent more string overruns.
- support -T
we don't turn the switch on to replace tar and cpio yet.
round has been tested on Solaris/x86 and Linux hosts.
* Add host tools cap_mkdb, ctags, m4, uudecode.
* Protect __RCSID() and __COPYRIGHT() better.
* Reduce the number of places that need to include "config.h", to keep
sources closer to their "vanilla" versions.
* Add more compat #defines and autoconf-checked functions.
files on standard input as an mtree(8) `specfile' specification, and
write or copy only those items in the specfile.
If the file exists in the underlying file system, its permissions and
modification time will be used unless specifically overridden by the
specfile. An error will be raised if the type of entry in the specfile
conflicts with that of an existing file.
Otherwise, it is necessary to specify at least the following parameters
in the specfile: type, mode, gname or gid, and uname or uid, device
(in the case of block or character devices), and link (in the case of
symbolic links). If time isn't provided, the current time will be used.
leaving the ansi stuff)
- use longlong_t instead of quad_t (etc), and rename *uqd*() -> *ull*()
- clean up the NET2_STAT stuff similar to ftpd; provide #defines and
macros which select which cast to use, etc
- clean up the NET2_FTS and NET2_REGEX #define use
a new volume upon premature end-of-volume (e.g. broken pipe). This is
especially useful in automated environments where error recovery cannot
be performed by a human.
Continue partial write(2) on signals (xwrite()).
Partial read(2) at a few places are also continued (xread()).
Add {read,write}_with_restart() hooks for porting on systems
which don't restart interrupted read()/write() calls.
Reviewed and discussed in tech-kern and tech-userlevel lists.
- minor cleanups to the options parsing code.
- add a cpio frontend.
note: a few GNU/svr4 cpio options are not supported yet (#ifdef
notyet), however all x/open ones are.
