behavior WRT to patterns lines up with the example in the documentation
and how other implementations do it as well since -A is a non-standard
option/behavior. Fixes items noted in PR#23776
- "cpio -i -t" should list the contents of a file, not extract it.
- Don't extract a file when only option "-d" is given.
Patch supplied by Paul Ripke in PR bin/26513.
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.
compare the lengths and then use memcmp() in the search code.
Speeds up one of my scripts by a facter of 2.
Increase the size of the variable hash table.
Cuts down time for script to execute from 60 seconds to 10.
Move variable search into a new function to hide the implementation
from most of the code, new version is slightly smaller than old.
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.
only used for syscall name <-> number translations, and the native array
is guaranteed to be superset of the former 'aout' and 'aoutm68k' arrays
this re-adds 'aoutm68k' support, and replaces change made in 1.14
g/c #include's which are no longer needed (including aout_syscalls.c), and
also add some comments for the emulations[] array
background process
This happens because we vfork, and then open a named pipe with O_RDONLY
and block in the child. We avoid this, by opening the file with O_NONBLOCK,
and then reset it if we are vforked. XXX: this is an ugly fix.
which was unnecessarily changed in revision 1.50 while fixing other bugs.
That is, exit the shell if the last command in a || or && compound statement
is not short-circuited, and exits with a false status. I.e., the following
will cause the shell to exit:
set -e
false || false
While this is not the prescribed behavior in SUSv3, it is what our man page
documents, and it is what all of the following implementations do:
NetBSD /bin/ksh (pdksh)
bash
zsh
Solaris 9 /bin/sh
Solaris 9 /usr/xpg4/bin/sh
Solaris 9 /usr/bin/ksh
Tru64 /bin/sh
HP/UX 11 /bin/sh
The "standard" seems to be wrong in this instance.
_NETBSD_SOURCE as this makes cross building from older/newer versions of
NetBSD harder, not easier (and also makes the resulting tools 'different')
Wrap all required code with the inclusion of nbtool_config.h, attempt to
only use POSIX code in all places (or when reasonable test w. configure and
provide definitions: ala u_int, etc).
Reviewed by lukem. Tested on FreeBSD 4.9, Redhat Linux ES3, NetBSD 1.6.2 x86
NetBSD current (x86 and amd64) and Solaris 9.
Fixes PR's: PR#17762 PR#25944
As mentioned in the previous commit, the switch statement in the longlink()
needed simplification and it was a bit incorrect. Only depend on the passed
type to determine what kind of gnu longlink to produce. Don't try to deduce
it from the archive file type.
- always put the @LongLink tag on the name, not the long-link name.
- pass in what type of long name record we want to create; one for long-name
or long-link name.
XXX: We should get rid of the switch too.
- Not enabled by default. Needs kernel option FFS_SNAPSHOT.
- Change parameters of ffs_blkfree.
- Let the copy-on-write functions return an error so spec_strategy
may fail if the copy-on-write fails.
- Change genfs_*lock*() to use vp->v_vnlock instead of &vp->v_lock.
- Add flag B_METAONLY to VOP_BALLOC to return indirect block buffer.
- Add a function ffs_checkfreefile needed for snapshot creation.
- Add special handling of snapshot files:
Snapshots may not be opened for writing and the attributes are read-only.
Use the mtime as the time this snapshot was taken.
Deny mtime updates for snapshot files.
- Add function transferlockers to transfer any waiting processes from
one lock to another.
- Add vfsop VFS_SNAPSHOT to take a snapshot and make it accessible through
a vnode.
- Add snapshot support to ls, fsck_ffs and dump.
Welcome to 2.0F.
