Hi, Do you mean creating it on start?
There is an open bug in the Debian bugtracker about this: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=616712 Two years ago I said "yes, Wt should create it": http://www.mail-archive.com/witty-interest@lists.sourceforge.net/msg02065.html But when I started to write the doc I promised in the Debian bugtracker, I realized there are several cases and subcases here. This is more or less what I have written, but I'm not satisfied with the solution to case 2. Please comment :-) ---8<------------------- Let's start with some facts: - the Wt webapp needs to be launched somehow - in the general case (production), it will be started automatically Case 1: wthttp webapp ================= I can think of three different subcases here: 1.1 WtHttp webapp started by init script --------------------------------------------------- In this case, IMHO it should be the init script the one to create the /var/run/wt directory and any other directories required by the application outside approot, including setting the appropriate permissions. Given that init scripts run with root permissions, this should not be a problem. 1.2 WtHttp webapp started by inetd ---------------------------------------------- Inetd starts services on demand. This case can be assimilated to either 1.1 or 2, depending on what we tell inetd to do: - If we tell inetd to run a script that creates /var/run/wt and any other directories required by the application, then this case is the same as 1.1. Should the script needs to create /var/run/wt and/or files or directories which require permissions other than those of the www-data user, then we must tell inetd to run the script as root, then change permissions (with su, for instance). - If we tell inetd to run webapp.wt directly, then this is like case 2 1.3 HTTP server forwarding to WtHttp webapp ------------------------------------------------------------ This is like case 2 Case 2: wtfcgi webapp ================= In this case, there is no init script: the app is run directly by the HTTP server. And frankly, I cannot think of a good solution: - The directory cannot be created by the the Wt webapp. It will fail because /var/run requires root permissions. - AFAIK, there is no way to tell the HTTP server: "hey, before forwarding a connection to my FCGI module, please create this directory/file". Even if there was, we hit the permissions problem again: that mkdir would run as www-data, not as root. The only solution I see is, again, an init script. The init script should be run before or at the same runlevel as the HTTP server to avoid race conditions. ---8<------------------- On Thu, Sep 1, 2011 at 11:02 AM, Wim Dumon <w...@emweb.be> wrote: > Pau, > > Should Wt try to create it's run directory if it does not exist, > according to the Linux Standard Base specification?
