- If mkdir() fails on a component (no matter what the error is),
stat() the result. If the stat() fails, print the error mkdir() generated.
Otherwise, if the result is not a directory, explicitly fail with ENOTDIR.
- Move the chmod() of last element to be done only if the mkdir() succeeded
(i.e, it wasn't an existing directory)
Fixes problem introduced in previous commit where "mkdir -p existing"
on a read-only file system would incorrectly return a non zero exit code,
whilst retaining the race-condition fix of the previous commit.
Thanks to simonb@ for sanity checking my fix versus the standards.
and in libkvm. Then teach ps how to show them to you.
Also, teach ps how to show the names for all the uids, the rest of the
group numbers, and the "group access list".
mtree(8) specfile), compare the "post write/copy" mtime against the
actual "pre write/copy" mtime instead of the mtime from the specfile.
This prevents warnings such as:
pax: File ./foo was modified during copy to archive
if the file's mtime in the file system is different to what's in the specfile.
(The resultant file will still get the specfile mtime ...)
Accidentally left eval = 1 when I was adding the extension which caused the rm command to return a 1 when it successfully removed a directory. Thanks to tron for catching it.
- sprinkle some fflush() to print filenames correctly.
- print a \n to stdout to fix formatting.
- English, consistently use "Cannot" in error messages.
some whitespace cleanup.
side. Sometimes it was compared to int, which was -1 on EOF, and on
unsigned char machines UPEOF was (unsigned char)-1. This worked
by chance because isalpha((unsigned char)-1) returns false usually,
but it does not when the locale is invalid!
0. Revert previous change for PR/18689. We always want to exit with
an error if we could not determine the archive format. Instead,
treat empty files specially. On list/extract we turn into no/op.
On append, we turn into archive.
code did not properly deal with the fact that the replacement patterns built
by the -X code were on the stack, happily saving pointers into last weeks'
stack into the REPLACE structures.
Now, the replacement string is strdup'ed so it doesn't matter where the
original expression came from or it's lifetime.
just try to create it and interpret any error appropriately.
this fixes a problem where multiple "mkdir -p" processes can race,
with the loser returning a spurious error.
- ansification
- format of output of jobs command (etc)
- job identiers %+, %- etc
- $? and $(...)
- correct quoting of output of set, export -p and readonly -p
- differentiation between nornal and 'posix special' builtins
- correct behaviour (posix) for errors on builtins and special builtins
- builtin printf and kill
- set -o debug (if compiled with DEBUG)
- cd src obj (as ksh - too useful to do without)
- unset -e name, remove non-readonly variable from export list.
(so I could unset -e PS1 before running the test shell...)
While a hard link to a symbolic link is not ruled out by POSIX-2001,
the ln(1) utility (sans -s) is to perform equivalent to the link(2)
function on its operands, which includes the resolution of symbolic
links in source_file arguments.

He says:
Ok the extra INTOFF is the one in exverror().
In almost all cases this doesn't matter because the longjmp()s
all end up in main() and the FORCEINTON call sorts it out
for the next command.
(There are a significant number of INTON/OFF mismatches through
the error paths...)
In any case the above failure can be 'fixed' by changing 2 (I think
they are both needed) INTON calls to FORCEINTON within evalcommand.
The following patch seems to work:
We should really look in the code and fix the INTON->INTOFF pairs.

into things like binary packages, and thus must be kept around
for backward compatibility.
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.

effects, and add double to it, so that it aligns doubles correctly too. This
is just a workaround to fix the sparc64 problem where ALIGN() is now defined
in some include file to be 16 instead of 8. Thanks to martin for debugging this.
the non-vfork case. Having said that, it would be nice if pipelines of
simple commands were vforked too. Right now they are not.
Explain that setpgid() might fail because we are doing it both in the
parent and the child case, because we don't know which one will come
first.
Suspending a pipeline prints %1 Suspended n times where n is the number
of processes, but that was there before. It is easy to fix, but I'll
leave the code alone for now.
Propagate isroot, throughout the eval process and maintain it properly.
Fixes sleep 10 | cat^C not exiting because sleep and cat ended up in
their own process groups, because wasroot was always true in the children.
Plus my changes:
- walking process group fix in foregrounding a job.
- reset of process group in parent shell if interrupted before the wait.
- move INTON lower in the dowait so that the job structure is
consistent.
- error check all setpgid(), tcsetpgrp() calls.
- eliminate unneeded strpgid() call.
- check that we don't belong in the process group before we try to
set it.
race conditions -- now we always synchronously wait for the job to finish.
In evalcommand(), add the same INTOFF/INTON locking as evalpipe(), to prevent
leaving internal state inconsistent, and also to insure that we synchronously
wait for the job.
-dynamic-linker=/libexec/ld.elf_so) if the BINDIR of the program being
built is /bin or /sbin.
The reason we do this is because now all programs *except* those in
/bin and /sbin (i.e. the "special cases") match the default the compiler
uses, which is what is used for things in e.g. xsrc, pkgsrc, and other
random 3rd party programs.

requirement...
