For example, mode computed from the following ACL is 0600: user:kamila:rwx--------C--:------:allow owner@:--x-----------:------:deny owner@:rw-p---A-W-Co-:------:allow group@:rwxp----------:------:deny group@:--------------:------:allow everyone@:rwxp---A-W-Co-:------:deny everyone@:------a-R-c--s:------:allow However, applying that mode (chmod 0600) changes the ACL into this: user:kamila:rwx-----------:------:deny user:kamila:rwx--------C--:------:allow owner@:--x-----------:------:deny owner@:rw-p---A-W-Co-:------:allow group@:rwxp----------:------:deny group@:--------------:------:allow everyone@:rwxp---A-W-Co-:------:deny everyone@:------a-R-c--s:------:allow In chmod(1) utility, there is an optimisation, which makes it not call chmod(2) if the mode of the file is the same as the new mode. Disable that optimisation for files which may have NFSv4 ACLs. Reviewed by: rwatson Approved by: re (kib) Notes: svn path=/head/; revision=195243

| | | | | | | | | | | | | | | | | | | | | | | | (EV_EXIT). The fork is still done as normal if any traps are active. In many cases, the fork can be avoided even without this change by using {} instead of (), but in practice many scripts use (), likely because the syntax is simpler. Example: sh -c '(/bin/sleep 10)& sleep 1;ps -p $! -o comm=' Now prints "sleep" instead of "sh". $! is more useful this way. Most shells (dash, bash, pdksh, ksh93, zsh) seem to print "sleep" for this. Example: sh -c '( ( ( (ps jT))))' Now shows no waiting shell processes instead of four. Most shells (dash, bash, pdksh, ksh93, zsh) seem to show zero or one.

* Properly flush input after an error in backquotes in interactive mode.Jilles Tjoelker2009-06-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | For parsing an old-style backquote substitution (`...`), a string "file" is used to store the contents of the substitution (with the special backslash processing done). If an error occurs, the shell cleans up all these files (returning to the top level) and flush the top level file. Erroneously, it first flushed the current file and then cleaned up all extra files, so that the top level file (i.e. the terminal) was not flushed. Example (in interactive mode): echo `for` echo This should not be printed Also noticeable in (in interactive mode): echo `(` The old version prints an extraneous prompt.

* Avoid leaving unnecessary waiting shells in many forms of sh -c COMMAND.Jilles Tjoelker2009-06-135-9/+35
| | | | | | | | | | | | | | | | | | | | | | | | | This change only affects strings passed to -c, when the -s option is not used. The approach is to check if there may be additional data in the string after parsing each command. If there is none, use the EV_EXIT flag so that a fork may be omitted in specific cases. If there are empty lines after the command, the check will not see the end and forks will not be omitted. The same thing seems to happen in bash. Example: sh -c 'ps lT' No longer shows a shell process waiting for ps to finish. PR: bin/113860 Reviewed by: stefanf Approved by: ed (mentor) Notes: svn path=/head/; revision=194128

With this check, it is no longer necessary to check for -T explicitly in that case. This is a useful bugfix by itself and also important because I plan to skip forking more often.

| | | | | | | | | | | | | | | | | | | | | More precisely, this gives precedence to an interpretation not using the '(', ')', '-a' and '-o' in their special meaning, if possible. For example, it is now safe to write [ "$a" = "$b" ] and assume it compares the two strings. The man page already says that test(1) works this way, so does not need to be changed. Interpretation of input with more parameters tries a bit harder to find a valid parse in some cases. Add various additional test cases to TEST.sh.

| | | | | | | | | | | | | | | | | | | A difference between the old and the new TTY layer is that the new implementation does not perform any post-processing before returning data back to userspace when calling read(). sh(1)'s read turns the TTY into a raw mode before calling select().
