hi everybody!
since some time now i am developing kports an advanced kde frontend for the
freebsd-ports and in future also pkgsrc and openbsd ports.
since the last release last summer i have gone through a complete rewrite and
right now am at the point where i monitor portupgrades output and am having
severe problems with portupgrade's behaviour.
the problem is: depending on certain conditions portupgrade doesnt show a big
part of the output. these conditions are:
the application is started as a subprocess of another application, e.g.
kdevelop and/or i use kprocess/qprocess to run the portupgrade command.
Could it be you are seeing the differences between stdout and stderr?
if i run the applicaiton on its own and use popen() and pipes to access the
output it works.
this might make it appear to be a problem of the kprocess implementation, however i am
pretty sure it is not. i have run the command with "| tee logfile" and the
logfile also only has part of the output. this whole problem has been discussed @
http://www.bsdforen.de/showthread.php?p=119650 (in german), so if you speak german you
could check that out. an example of the problem:
i run the command "portupgrade -v -y -N -PP games/angband" without root
previliges (this way the process is over pretty quickly). if run from inside a unix
system pipe (file descriptor opened with popen and read with fgets) the output looks like

however the same code, run as a subprocess of kdevelop misses the code colored in red.
i have also checked the environemnt inside those process and tried encapsulating the command in "sh -c" without any results...
now am out of ideas....
thanks for any help
