4462e9454f use puffs_daemon() instead of daemon() 2007-11-16 18:39:01 +00:00

ec865a5b29 Actually, daemonize the file servers before mounting. I might require 
at some point that the local protocol handler does not change after
the file system has been mounted.

4b0f2948e2 Pull the daemonizing code out of the library mainloop into the file 
servers.  Calling daemon() (i.e. fork()ing) inside a library can
cause nice surprises for e.g. threaded programs.  As discussed with
Greg Oster & others.

f8326bf98e Move puffs to a two clause license where it already isn't so. And 
as agc pointed out, even files with the third clause were already
effectively two clause because of a slight bug in the language...

1d9d9332f5 Use SETBACK_NOREF instead of SETBACK_INACT to control node removal. 
Avoids one round of inactive (wheee!).

48d5a49e1f "support" vop_poll enough for testing purposes. In short, yield every 
poll request for a few seconds before returning.

9550017a8d Adapt to changes with mounting file systems. 
Introduce a parameter -r to control the root node type.  For example
"dtfs -r 'lnk /etc' /puffs" mounts dtfs with the root node as a
symbolic link to /etc:

jojonaru# ./dtfs -r 'lnk /etc' /puffs
jojonaru# ls -l /puffs
lrw-rw-rw-  1 root  wheel  4 May 17 14:06 /puffs -> /etc
jojonaru# cd /puffs
jojonaru# pwd
/etc
jojonaru#

Extra credit for figuring out how to unmount this file system with
umount(8).

Likewise, "dtfs -r 'chr 2 12' /puffs" makes /puffs (i386) /dev/zero etcetc.

d583f4a1ec Unmount frequently requires some test code, so define it here as 
a dummy instead of libpuffs to make plugging the test code in easier.

2893a07834 Default to inactive-on-demand, use inactive setback to request inactive 
to be called for a removed node (for unix open file semantics).

37dd7942fc Instead of keeping on adding parameters to puffs_mount(), make it 
only take the bare essentials, which currently means removing
"maxreqlen" from the argument list (all current callers I'm aware
of set it as 0 anyway).  Introduce puffs_init(), which provides a
context for setting various parameters and puffs_domount(), which
can be used to mount the file system.  Keep puffs_mount() as a
shortcut for the above two for simple file systems.

Bump development ABI version to 13.  After all, it's Friday the 13th.
Watch out!  Bad things can happen on Friday the 13th. --No carrier--

69fe36da66 dtfs (*): a very simple in-memory file system providing an example on 
how to use libpuffs

this is not installed into the binary distribution just yet

*) you can call it either "Delectable Test File System" or
"Detrempe File System", depending on what you think will result
in more puffing
