(23:16:29) anth_r: powerman-asdf: it's good in many cases, but it's not generalizable.
(23:17:13) anth_r: that is, for example (from plan9; i don't have an inferno in front of me to test, but the idea is the same):
(23:17:15) anth_r: :; ns | grep '#\|'
(23:17:15) anth_r: mount  '#|/data1' /mail/fs 
(23:17:30) anth_r: there's no way to tell what "#|" refers to in that context.
(23:18:07) powerman-asdf: anth_r: but it can be unmounted
(23:18:15) powerman-asdf: without knowing it's source
(23:18:15) anth_r: other things like that, too. i don't believe the attach specifier, if given, shows up anywhere, so all dossrv thing will look the same.
(23:18:43) anth_r: powerman-asdf: i'm not sure that's always true. at least not without unmounting *everything* on the target, which you don't always want to do.
(23:19:14) anth_r: i mean the "i'm not sure" literally - i don't know. is it? i didn't think so, but i could certainly believe i'm wrong.
(23:20:18) powerman-asdf: so, we can: 1) readdir to get all Qid's of same-named file; 2) read first file; 3) in loop, unmount every mount point one-by-one, and check stat() of this file - if it Qid changes, then read next file and continue
(23:21:40) anth_r: from the same window as above (again, plan9; inferno could behave differently here):
(23:21:42) anth_r: :; unmount '#|/data1' /mail/fs 
(23:21:43) anth_r: unmount: /mail/fs: not in union
(23:22:31) anth_r: #| clearly is, but the #| referred to in the ns table isn't something i can get at.
(23:25:39) powerman-asdf: anyway, I decide to try something less invasive (than patch /dis/man to spawn/forkns/unmountall to read INDEX files) first. probably because of FUD you throw on me. :)
(23:26:31) anth_r: i think that's probably good. i think if you re-export anything, you'll totally mask the ability to see that, anyway.
(23:27:25) powerman-asdf: I run ramfile(4) on /chan/man-{1-10}-INDEX, and join contents of all INDEX files in that ramfile(s), then bind it over man/*/INDEX. This is done in /opt/setup.sh which bind opt packages man/*/ over system /man/*/.
(23:27:39) powerman-asdf: here is it: http://pastebin.com/JiVmNp2s 
(23:32:42) powerman-asdf: not as general as initial idea to patch /dis/man, but, you right - binding something over /man/*/INDEX doesn't always mean "append" operation, sometimes it can be "replace", and in this case general namespace unrolling and appending all INDEX files by /dis/man will do the wrong thing

(14:36:41) powerman-asdf: about two weeks ago I've blame here rand->rand() to be not enough random even for game… but it turns out it was my mistake. :(
(14:38:17) powerman-asdf: I've used sys->millisec() to seed it, and that's was the problem. I think it's include current time, but it isn't, and start from 0 on each emu start - so I've get same seed value often enough, and thus get same random numbers and same/similar generated map in game.
(14:38:51) powerman-asdf: using daytime->now() as seed result in much better random numbers from rand->rand()
(14:42:54) doublec: good catch!

(18:10:53) powerman-asdf: is vim syntax highlight exists for inferno's sh and mkfile syntax?
(18:28:25) raphaelsc [~raphaelsc@201.78.103.174] entered the room.
(19:10:18) leetspete: powerman-asdf: 'setf make' is 90% working, except the variables and some targets.  I don't know of one for the shell, though.
(19:11:24) powerman-asdf: for the shell I'm using rc's syntax, but it also only 90% working (${split ...} break it, etc.)
(19:12:48) powerman-asdf: anyway. I'll try to learn vim syntax file's syntax and implement them both. :-/
(19:21:42) leetspete: It's a scary syntax...be careful...
(19:22:06) powerman-asdf: it's not scary. just feature rich a.k.a. complicated
(19:22:17) raphaelsc left the room (quit: Quit: Leaving).
(19:22:26) powerman-asdf: been there, done that. many years passed, forget everything :)
