2019-07-15Explain in which circumstances trailing slashes can be omitted afterIngo Schwarze
the g and G commands, and polish the wording a bit explaining empty command lists. Closing a gap in the manual reported by <mazocomp at disroot dot org>. OK jmc@ martijn@
2019-07-12Minor polishing:Ingo Schwarze
* Delete a stray blank from the command line synopsis and add the missing .Ar markup to it. * Do not mention the terminating newline for the empty command since it isn't mentioned for any other command either. * Make the description of the empty command easier to understand. Joint work with martijn@ and jmc@.

2019-07-01sleep(1): simplify argument parsingcheloha
- No need for intermediate variables, just build the timespec directly - Use for-loops so we modify "cp" on a single line in each loop - Parse subseconds with one loop: less code, easier to read, etc. - Improve the subsecond parsing comment: make our intent really obvious ok schwarze@

2019-06-28When system calls indicate an error they return -1, not some arbitraryTheo de Raadt
value < 0. errno is only updated in this case. Change all (most?) callers of syscalls to follow this better, and let's see if this strictness helps us in the future.

2019-06-24Partial revert of rev. 1.151:Ingo Schwarze
Reference the First Edition (1989) of Bolsky/Korn which is about ksh88, the shell the OpenBSD ksh(1) descends from (via pdksh). The Second Edition (1995) of the book is about ksh93 which we don't provide. Pointed out by Andras Farkas on bugs@.

2019-06-23add "ps -o pledge" option, which prints a comma-seperated list of pledgesTheo de Raadt
active on each process. So go forth and "ps agux -o pledge" to find pledges which can be improved. (I hesitated adding this before because I am afraid of people enforcing extra-strict pledge in programs without testing all the use cases -- thereby breaking software).
2019-06-23Export unveil state so that ps(8) can show it. Two new status flags,Theo de Raadt
you'll see one, or neither. 'u' - process installed unveils, but not yet locked with unveil(0,0) or pledge w/o "unveil" 'U' - process has installed unveils, and locked. ok rob

2019-03-24detect -t argument being too long, rather than truncatingTheo de Raadt
2019-03-2416 chars is not enough for the maximum reach major() and minor()Theo de Raadt
could have, so let's formally expand the buffer to what it needs to be.
2019-02-20When evaluating an arithmetical expression, for example inside $(()),Ingo Schwarze
never do substitution (neither parameter, nor command, nor arithmetic, nor tilde substitution) on the values of any variables encountered inside the expression, but do recursively perform arithmetical evaluation of subexpressions as required. This makes behaviour more consistent, without hindering any behaviour promised in the manual page. A quirk originally reported by Andy Chu <andychup at gmail dot com> was that in the past, when encountering an array index, the shell would not only do evaluation, but also substitution on the array index, even though substitution would not be done on the expression in general. tobias@ contributed to initial efforts of understanding the quirk. patch tested in a bulk build by naddy@ "please commit" deraadt@

Give the same treatment if /dev doesn't exist. While things will be real interesting without /dev there is no reason to stop ps(1). Fix suggested by & OK deraadt OK millert
2019-02-05dev_t is signed to permit passing -1 as an invalid condition, but theTheo de Raadt
decomposition into major and minor is unsigned, so we should print them with %u instead of %d. ok guenther

Not standard, but supported at least by GNU cp, IllumOS, NetBSD, FreeBSD, DragonflyBSD. No need to be gratuitously different. This should also allow us to drop patches in ~10 ports. Based on an initial diff by benno@ with input from sthen@ and jmc@ ok benno@ danj@ sthen@ martijn@ deraadt@

2019-01-14Fix three more buglets:Ingo Schwarze
1. Another off-by-one: if a mail file name ends in an (escaped) percent sign, do not forget to check whether the next byte is the percent sign introducing the message (MAILPATH='filename\%%msg'). 2. If the message is empty, use the default message rather than printing a blank line (MAILPATH='filename%'). 3. If the file name is empty, don't bother with mballoc(): the subsequent stat(2) can never succeed. (MAILPATH='%msg'). Found while reviewing the previous commit by tedu@. OK tedu@.
