Public bug reported:
Binary package hint: dhelp
The /etc/cron.weekly/dhelp cron job is used by the dhelp package to
rebuild the debian help index (file /var/lib/dhelp/documents.index) by
deleting it and re-creating it.
However, if the umask of user root is more restrictive than the default
022, then the file may end-up being non-readable by the web server user
account (www-data) and thus the search does not work any more (shows no
results). This was the case in my system where the default umask was set
to 077.
ubuntu version: 9.10
dhelp version: 0.6.17ubuntu1
Until this is get fixed upstream (change to ruby code to invoke a chmod
call), the following patch in the cron job can fix this issue. It
launches a sub-shell (to protect from an unwanted pertaining umask
change in case of a script error) where it changes the umask and calls
the rebuild method as usual:
