* sh: Add test for arithmetic expansion in [x-y] pattern range.Jilles Tjoelker2017-05-132-0/+11

* sh: Fix executing wrong command with ${unsetvar#$(cmdsubst)}$(cmdsubst).Jilles Tjoelker2017-03-103-1/+9
| | | | | | | | | | | | | | | | | | | | | The parsed internal representation of words consists of a byte string with a list of nodes (commands in command substitution). Each unescaped CTLBACKQ or CTLBACKQ | CTLQUOTE byte corresponds to an entry in the list. If param in ${param#%##%%word} is not set, the word is not expanded (in a deviation of POSIX shared with other ash variants and ksh93). Erroneously, the pointer in the list of commands (argbackq) was not advanced. This caused the wrong command to be executed later if the outer word contained another command substitution. Example: echo "${unsetvar#$(echo a)}$(echo b)" wrote "a" but should write "b". MFC after: 1 week Notes: svn path=/head/; revision=315005

* ps(1): Fix -w + UNLIMITED handlingConrad Meyer2017-03-071-1/+1
| | | | | | | | | | | | | | | | | | | | | A follow-up fix for r314685. Because the -w flag is parsed after ps(1) infers termwidth from COLUMNS and stdout, and UNLIMITED happens to be the zero value, the single -w flag in combination with a non-terminal stdout or COLUMNS=0 could result in output truncated at 131 characters. (Despite the output being unlimited without -w.) Obviously, adding more -w shouldn't truncate output lines. The committed patch is from bdrewery@, and I've reviewed and tested it.

* sh: Fix crash if a -T trap is taken during command substitution.Jilles Tjoelker2017-03-044-2/+19
| | | | | | | | | | | | | | | | | | | Code like t=$(stat -f %m "$file") segfaulted if -T was active and a trap was taken while the shell was waiting for the child process to finish. What happened was that the dotrap() call in waitforjob() was hit. This re-entered command execution (including expand.c) at a point not expected by expbackq(), and global state (unallocated stack string and argbackq) was corrupted. To fix this, change expbackq() to prepare for command execution to be re-entered. Reported by: bdrewery MFC after: 1 week Notes: svn path=/head/; revision=314686
* ps(1): Only detect terminal width if stdout is a ttyConrad Meyer2017-03-041-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If stdout isn't a tty, use unlimited width output rather than truncating to 79 characters. This is helpful for shell scripts or e.g., 'ps | grep foo'. This hardcoded width has some history: In The Beginning of History[0], the width of ps was hardcoded as 80 bytes. In 1985, Bloom@ added detection using TIOCGWINSZ on stdin.[1] In 1986, Kirk merged a change to check stdout's window size instead. In 1990, the fallback checks to stderr and stdin's TIOCGWINSZ were added by Marc@, with the commit message "new version."[2] OS X Darwin has a very similar modification to ps(1), which simply sets UNLIMITED for all non-tty outputs.[3] I've chosen to respect COLUMNS instead of behaving identically to Darwin here, but I don't feel strongly about that. We could match OS X for parity if that is desired.
