2018-01-16Introduce internal_warningf() and mark internal_errorf() as noreturnJeremie Courreges-Anglas
This helps tools like scan-build, and follows the example of warningf() and errorf(). ok anton@
2018-01-16Stop constructing the ulimit optstring passed to ksh_getopt() at runtime sinceanton
it's rarely subject to change. While here, unifdef RLIMIT_VMEM. ok jca@

2018-01-15Don't try to open HISTFILE if the variable is unset.Jeremie Courreges-Anglas
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@

2018-01-12Some more tweaks to NOTESJeremie Courreges-Anglas
- 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
2018-01-08update comments that were left behind in the recent unifdef JOB commitSebastian Benoit
from Klemens Nanni, thanks.
2018-01-08Drop two outdated entriesJeremie Courreges-Anglas
Namely POSIX character classes and tilde expansion within parameter substitution. While here, kill a useless line and fix a typo. From Klemens Nanni

from kshe
2017-12-27Add -Wshadow to Makefile and fix the resulting warnings. Many ofTodd C. Miller
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@
2017-12-26The hack for /dev/fd support on systems without it was removed aTodd C. Miller
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@

2017-12-12Document change in the default shell prompts.Theo Buehler
Discussed with and ok jmc
2017-12-12Include hostname in shell prompts by defaultTheo Buehler
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
2017-12-07Drop the unused second argument from set_prompt(). It used to be used forTheo Buehler
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

2017-11-21Initialize *histbase to NULL to fix a bus error in emacs editing modeTheo Buehler
found by anton. To reproduce, run "env EDITOR=emacs MALLOC_OPTIONS=J ksh" then press "^[_". ok anton, jca
2017-11-02Switch calloc(3) back to malloc(3). The call to calloc was introducedTheo Buehler
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

We may have read two bytes from the file, but history_load() needs to call rewind(3) anyway. ok benno@

2017-08-29Kill a useless setlocale() queryJeremie Courreges-Anglas
Pointless since the removal of the setlocale() call in main.c:rev1.82, the emacs-usemeta flag isn't used in the code since 2012. This kills a chunk of code in a statically linked ksh. ok millert@
2017-08-28Don't bother setting freed history lines to NULL.Jeremie Courreges-Anglas
Dead code that could send the wrong hint to an unsuspicious reader. The code should walk use 'history' & 'histptr' to walk the array. ok millert@, "go for it" tb@
2017-08-28Put history_write() in line with other functions that walk historyJeremie Courreges-Anglas
One method is enough: only access history lines between 'history' and 'histptr'. Pointers outside these bounds might be invalid. ok millert@, "go for it" tb@
