When you close ash, it'll append all of its new history to .ash_history, completely re-load .ash_history (other instances of ash might have written to it, and re-loading trims it to MAX_HISTORY), write the trimmed history out to .ash_history.$PID.new, and rename .ash_history.$PID.new to .ash_history.
The used code for this is pretty solid (look for save_history() in libbb/lineedit.c), and I don't see any direct cause as to why you lost your history
. The only clue we have is that rename() somehow failed, since you still got .ash_history.XXXX.new files. It's rather odd though that you experienced this twice - the only other report is from Mentalist Traceur, but he mentioned that the device was unstable. You could add something like the following to your ~/.profile file. This will backup your old history to /home/user/hist_bak/ when you close ash. It won't solve the issue you're experiencing, but at least you won't lose all of your history. I'm sorry I can't be of more help.
Code:
trap 'NAME=`date +%Y%m%d_%H%M%S`_bak && \ cp /home/user/.ash_history /home/user/hist_bak/$NAME' 0

Since this thread got bumped anyway, let me take this opportunity to call for testers 
. Busybox-power 1.19.3power4 has been in extras-testing for a pretty long while now, and we most certainly can't leave out those extras users from shiny new versions, can we?
Also, for those that have noticed, busybox-powers' git repo has BusyBox 1.19.4 in it since a while now. It isn't pushed to the repositories because there is no code change between 1.19.4 and 1.19.3 + hotfixes, of which busybox-power 1.19.3power5 consists. Just a FYI

Hi,
Got a problem with creating user and group, at least, the postinstall script from the icecast2 deb had!
Can't install this app and busybox power report a prob in user and group creation, any ideas?

The line that causes this error in the postinst script is:
Code:
adduser --system --disabled-password --disabled-login \ --home /usr/share/icecast2 --no-create-home --group icecast
The solution is rather simple though. Execute:
Code:
apt-get install adduser
. The postrm script also uses utilities from the adduser package (namely: deluser and groupdel), so you shouldn't uninstall the package right after installing icecast2. It seems like the package maintainer simply forgot to add a dependency on adduser to icecast2.

just for the reports:
I also faced this a few times. But afair always after a hard shutdown (real sw_res). I found total senseless entries in history or even lines of my e-mails (which really scared me the first time
)...But just loosing the history sometimes is just a inconvenience, no more. And the positice effects of busybox enhanced is SO much more!
Thanks again for that package and support.

However, Maemo isn't shipped with adduser at all! Busybox-power does provide an adduser applet, but it takes different arguments than the postinst tries to use.Code:adduser --system --disabled-password --disabled-login \ --home /usr/share/icecast2 --no-create-home --group icecast
The solution is rather simple though. Execute:
and icecast2 will install flawlesslyCode:apt-get install adduser
Thank you very much IDont, I haven't thought about it myself...
Thanks also for the hard work about busybox-power, it's a huge enhancement for the N900.
Have a nice day.

Happened again, this time after using preenv from the command line. Could it be related?
Update: I'm still not able to (re)produce any kind of issue with the history handling. This issue is driving me nuts! I must have looked over the code a hundred times by now. What completely puzzles me, are the reports about the completely unrelated text in .ash_history; I can't seem to relate that to BusyBox in any way
