[9fans] import/export -B
I am a little confused by import/export -B (backwards). The only bit I don't get is why you have to supply a mountpoint to import. Surely import will always be running from listen and as such it will not be in any useful namespace so why mount anything? from the manpage: Suppose that the machine moscvax has access to a private file server containing public web pages that need to be served by the less-trusted server webvax. Webvax runs the following listener (see listen(8)) on TCP port 999: #!/bin/rc import -B -s rowebfs /usr/web /bin/restarthttpd When moscvax boots, it runs exportfs -R -r /usr/web -B tcp!webvax!999 to serve a read-only copy of /usr/web to webvax. When webvax gets the call, import mounts the served tree onto its own /usr/web and then runs /bin/restarthttpd to restart httpd(8). It seems to me that my restarthpptd script will be 'unmount /usr/web; chmod 600 /srv/rowebfs' I find it strange that the mountpoint is not optional (as long as -s srv names exists). perhaps I am missing somthing? or maybe its just a quirk? -Steve
[9fans] Simple calculator/spreadsheet for Acme
I wrote a small tool that parses variables and code in an Acme window, runs code the code with the variables as input, and replaces the variable values in the window with the values the code outputs. The code can be any script, but I made wrappers to make it very easy to write scripts in rc and Go. Here's my example from the blog post: Bob's age=30, he is yearsleft=0 years away from retirement (calc). #!/usr/bin/env calcgo yearsleft = 55 - age If you middle click calc, it runs the Go script (generated, compiled, linked, and executed by calcgo), and replaces the value of yearsleft with 25. You can also increment values, etc., so running calc more than once can to interesting things. I'm not really tuned into the Acme/Wily/Oberon community, so I don't know if this is a common way to work, but this uses what I think might be a good interaction model for scripts -- take input from a window and put the results back into the window. It's kind of like HTTP's request/response idea. This could be extended to handle more than just simple data, like tables (which my old calc for Ober did, follow that link in the post if you're interested). Here's my blog post about it: this-statement-is-false.blogspot.com/2010/10/calculatorspreadsheet-tool-for-acme.html Here's a link to the source (3 rc scripts): http://repo.or.cz/w/bills-tools.git/tree/HEAD:/calc Bill
Re: [9fans] sheevaplug port available
There's a good chance your /tmp issue is not permissions, but a lack of /tmp being mounted. If your hostowner doesn't have a lib/profile or its lib/profile doesn't mount /tmp, then you won't be able to write anything to it. That was definitely it. I had been logging into the hostowner profile but hadn't run newuser. I ran it, and then the pull worked. I did have to use the -s sys/src flag, but anyway, all up to date. So looks like having a profile for hostowner is required. Good to know. When rebuilding, I did have to change the permissions on /mail/lib/gone.* in order for 'mk install' to complete, though I suppose I could have added bootes to the upas group... but anyway, thanks all for the help!! -Ben winmail.dat
