* Document that rand() returns non-deterministic random numbers unless atim2020-06-171-3/+12
| | | | | | seed is explicitly set. OK millert@
* Fix strlcpy() size parameter in refldbld(), it was a byte too small.millert2020-06-162-17/+21
| | | | | While here, add proper bounds checking for the partial match case in refldbld() too and check strlcpy() return values throughout.
* Integrate the bsd-features branch from awk github.millert2020-06-138-14/+339
| | | | | Implements the gensub(), systime() and strftime() functions for greater gawk compatibility.
* POSIX doesn't permit an unescaped '/' in an extended regular expression.millert2020-06-135-21/+35
| | | | | | | | Unlike upstream awk, ours has historically allowed unescaped '/' inside a bracket expression for compatibility with other awk implementations but the check was too simple-minded. This improves the matching to allow things like /[]/]/, /[^]// and '/[abc[:digit:]/@#]/' To enable strict POSIX compliance, set POSIXLY_CORRECT.
* Use setlocale(LC_CTYPE, "") instead of setlocale(LC_ALL, "")millert2020-06-111-2/+2
| | | | This matches upstream awk and OpenBSD only implements LC_CTYPE anyway.
* Fix length parameter to strlcpy, inputFS is a pointer.millert2020-06-111-2/+2

* The errcheck() function treats an errno of ERANGE or EDOM as somethingguenther2020-06-081-3/+11
| | | | | | | | | | | | to report, so make sure errno is set to zero before invoking a function to check so that a previous such errno value won't result in a false positive. This could happen simply due to input line fields that looked enough like floating-point input to trigger ERANGE. Problem noted by Jordan Geoghegan (jordan (at) geoghegan.ca), with clue from Ze' Loff (zeloff (at) zeloff.org) ok millert@
* Merge a missing fix from awk-12202012 and update the version and FIXES.millert2020-02-274-7/+25
| | | | This was the last awk release before the move to github.
* claudio noticed that "exit" inside the main {} clause still runs the EXITderaadt2020-01-221-7/+10

* POSIX requires that awk support \v and \a escapes. I used '\007'millert2018-01-242-2/+8

* rename dprintf macro to DPRINTF to avoid collision with libc posix dprintf.deraadt2017-10-097-51/+51

* Add pledge support in awk and make awk -safe actually safe.doug2015-10-101-1/+17
| | | | | | | | | | | | | | awk -safe was introduced back in 1997 to stop awk from doing file output, execute commands or access the environment. The lexer rejected programs when it saw awk commands that would write, exec or env. Beyond that, it wasn't safe from write/exec/env during program execution. With pledge "stdio rpath", the kernel is now enforcing the awk -safe mode restrictions at runtime (other than env). Based on a diff by deraadt@ ok deraadt@ beck@
* Avoid .Ns right after .Pf, it's pointless.schwarze2015-09-141-5/+5

* When rand() was made fully random, the return value of srand() wasderaadt2015-09-051-4/+8
| | | | | | | | | also affected incorrectly. Noticed by Stephane Chazelas. This reverts the return value of srand() to the old (not very useful) behaviour. This also allows toggling rand() to strong/weak based upon whether srand() is called without/with an argument. Long discussion and work with millert ok beck

* Userland reallocarray() audit.doug2014-10-111-2/+2
