default prompt by not including a space after the character; diff from scott cheloha
2017-08-16Explicitly say that expr(1) handles decimal integers only, as mandatedIngo Schwarze

2017-08-15Remove expensive pointer check in afree()Jeremie Courreges-Anglas
The check added in rev 1.8 walks the whole freelist to catch cases where an unknown pointer is passed to afree(); but it can't catch cases whether the struct link has been corrupted by an invalid memory write. And it becomes very expensive when you have lots of items in an area (for example with a huge HISTSIZE). Discussed with & ok millert@ tb@

2017-08-11Check whether the first two characters of $HISTFILE are the magicTheo Buehler
characters of the old binary ksh history file. In that case ignore the history file after displaying an error once. Prevents annoying repeated 'history file is corrupt' messages in $HOME on NFS setups suffered by henning and makes the migration from the old to the new history file format safer. ok henning, tweaks & ok jca

2017-07-26Postpone printing of prompt if filec is enabled in csh. Any I/O should beanton

2017-07-04Backout previous due to a bug discovered by zhuk@ that requires some tinkeringanton
and is not an easy fix for now.
2017-07-04Add support for pattern substitution to variables in ksh using a common syntaxanton
borrowed from ksh93. Survived a ports build performed by naddy@ and encouraged by many.

now. ok schwarze@
2017-06-25Don't output partial UTF-8 characters in ksh emacs mode. Instead, try to read aanton
complete UTF-8 character first. Fixes an issue while running ksh in tmux where UTF-8 characters inserted in columns other than the last one are discarded. With help from nicm@ and schwarze@ who also wrote the UTF-8 validation, thanks! ok schwarze@

2017-06-21Replace usage of TIOCSTI in csh using a more common IO-loop where ICANON isanton
disabled and a single char of input is read at a time. This requires the line editing capabilities provided when ICANON is enabled to be implemented. With help and feedback from deraadt@
2017-06-20'^T' is documented to be bounded to transpose-chars while in emacsBryan Steele
mode, not "stuff". While here, remove the poorly described "stuff" and "stuff" bind functions as well.. In the unlikely event anyone has those in .kshrc, they'll need to be removed. ok anton@
2017-06-20Don't try to close every single file descriptor up to _SC_OPEN_MAX in csh.anton
Instead, close the fds that reside in between the gaps of used fds and once the largest used fd is reached call closefrom(). ok deraadt@

2017-06-01The fact is simple: Subshells have the same PPID as the current shell.Theo Buehler
What is not so simple is squinting hard enough to conclude that POSIX actually says that. I'm still not sure how to do that. Problem with the shell manual pointed out by "Choose a display name". ok otto, halex, jmc

2017-05-29Change the mmap(2)-based binary history file with lots of magic and aTheo Buehler
tendency for corruption to a simpler plaintext version. To convert your current ksh history to plaintext, issue fc -ln 1 | sed 's/^ //' > ~/ksh_hist.txt before upgrading and use ksh_hist.txt as HISTFILE after the upgrade. Original patch by marco in 2011. Ported to current during g2k16 by me. Testing, bugfixes and improvements in joint work with natano. Additional testing by anton and mestre. Includes some tweaks by anton. Committing now to shake out remaining bugs before 6.2 is cut. ok deraadt, mestre, anton, sthen
2017-05-28chown: Remove SUPPORT_DOT ifdef - it's on by default for 22 yearsAdam Wolk
The old syntax was deprecated 25 years ago when the utility was first standardised in IEEE Std 1003.2-1992 ("POSIX.2"). There was no POSIX version of chown with the dot separator. Let's stop pretending that it will ever go away. OK jung@, deraadt@, jmc@

2017-05-12Improve UTF-8 handling on lines that are wider than the terminal,Ingo Schwarze
in two respects: 1. During output in x_e_putc(), when counting display columns, skip UTF-8 continuation bytes. Fixes backward movements that cause horizontal scrolling. 2. After deleting characters, recalculate the last byte that fits on the line. Patch from <Anton dot Lindqvist at gmail dot com> on tech@. OK millert@ tb@
