* Keep the time pipeline's stack in tactkn2018-04-241-4/+8
| | | | | | | | | | Revision 1.28 (2008) fixed stack abuse by allocating a new one and effectively clearing it. This broke pipelines such as $ time for i in . ; do : ; done /bin/ksh: : is read only Prompted by tb, OK millert, tb, jca
* Count $SECONDS with CLOCK_MONOTONIC.cheloha2018-04-131-5/+12
| | | | | | Keeps $SECONDS advancing uniformly and independent of wall clock jumps. ok jca@
* Support 64 bit integers on 32 bit architectures.tobias2018-04-0914-58/+61
| | | | | | | No binary change on amd64 and there should be no differences on any other 64 bit architecture either (because long = int64_t). ok cheloha, tb

| | | | | | | mode, to avoid potential confusion pointed out by andreas dot kahari at icm dot uu dot se on misc@. Patch minimally tweaked based on a comment from jmc@. OK anton@ jca@ jmc@ on the previous version without the tweak.
* Remove code that has been disabled since 1999. From Michael W. Bombardieri whoanton2018-01-201-18/+1

* Introduce internal_warningf() and mark internal_errorf() as noreturnjca2018-01-1617-79/+97
| | | | | This helps tools like scan-build, and follows the example of warningf() and errorf(). ok anton@
* Stop constructing the ulimit optstring passed to ksh_getopt() at runtime sinceanton2018-01-161-16/+2
| | | | | | it's rarely subject to change. While here, unifdef RLIMIT_VMEM. ok jca@

| | | | emacs.c:1041:2: warning: Value stored to 'cp' is never read
* Don't try to open HISTFILE if the variable is unset.jca2018-01-151-4/+3
| | | | | | | str_val returns null, not NULL, if the variable isn't set. The erroneous check means that we later tried to open(""). ok millert@ tb@ anton@ benno@

* Some more tweaks to NOTESjca2018-01-121-11/+6
| | | | | | | | | | | | - it's safe to assume that there's no plan to write "an `agent' to execute unreadable/setuid/setgid shell scripts" - the BUG-REPORTS file has been removed - update the entry for FPATH, ksh93 also documents the described behavior - kill entry about octal and hex notation in arithmetic expressions (supported) - typos Feedback from Klemens Nanni
* update comments that were left behind in the recent unifdef JOB commitbenno2018-01-081-15/+15
| | | | from Klemens Nanni, thanks.
* Drop two outdated entriesjca2018-01-081-6/+2
| | | | | | Namely POSIX character classes and tilde expansion within parameter substitution. While here, kill a useless line and fix a typo. From Klemens Nanni

* Add -Wshadow to Makefile and fix the resulting warnings. Many ofmillert2017-12-2712-70/+66
| | | | | | | the warnings are due to the use of globals with generic names, specifically "options" and "path". I've renamed "options" to "sh_options" since it holds the shell options and "path" to "search_path". OK jca@ tb@
* The hack for /dev/fd support on systems without it was removed amillert2017-12-261-27/+18
| | | | | | | | long time ago. Update the comments and replace test_stat() calls with stat() since test_stat() now just calls stat() directly. Also rename the "mode" parameter to "amode" in test_eaccess() to match access(2) and make it clear that this is the access mode and not the file mode. OK jca@

* Include hostname in shell prompts by defaulttb2017-12-122-4/+5
| | | | | | | | | | | | | | | With tmux, ssh and vmd, we tend to open shells on many different hosts simultaneously and the default prompts '$ ' and '# ' for {,k}sh as well as '% ' and '# ' for csh become dangerous: it's very easy to issue a command on the wrong host. This can easily be avoided by displaying the hostname in the prompt. Everything beyond "hostname{$,#,%} " is going to be a matter of taste, so we left it at that. If you use an FQDN, only the first part (the output of 'hostname -s') will be printed. requested by and ok deraadt; mostly positive feedback many ok anton, brynet, bcallah and others
* Drop the unused second argument from set_prompt(). It used to be used fortb2017-12-074-9/+9
| | | | | | | | early special casing of ! and !! in the PS1 expansion. This was removed from set_prompt() as part of the implementaion of the character count toggles \[ and \] back in 2004. ok jca
* Follow emacs mode and remove the interactive "version" function.tb2017-11-271-19/+2

* Remove the "version" interactive function in emacs mode.jca2017-11-261-32/+1

* Fix some incorrectness related to Emacs editing mode in ksh:anton2017-11-222-11/+17
| | | | | | | | - Keep the order of bindings in sync between the manual and implementation - Fix wrongly documented bindings in the manual - Break out commands without a default binding in the manual ok jmc@ tb@
* Initialize *histbase to NULL to fix a bus error in emacs editing modetb2017-11-211-1/+2

* Switch calloc(3) back to malloc(3). The call to calloc was introducedtb2017-11-021-2/+2
| | | | | | | | | | by the plaintext history diff, but the code that may have depended on this was since removed from history.c. None of the code introduced between the plaintext history commit and now depends on calloc(3). This way we can again use malloc.conf(5)'s J option to recognize use of uninitialized memory. ok jca
* Kill needless rewind(3) call in hist_init()jca2017-10-231-3/+1
| | | | | We may have read two bytes from the file, but history_load() needs to call rewind(3) anyway. ok benno@

* Keep histptr inside of the allocated history arrayjca2017-09-071-4/+12
| | | | | | histptr == history -1 means that the history is empty, but the behavior is then undefined. Allocate an extra array entry to work around this. Input & ok tb@
