[9fans] unvac bug

[9fans] unvac bug

[hugo rivera]

hi there,
there is a strange bug in unvac from p9p. When you vac a file tree
with the -a option, to have something like 2009/0311/yourtree, and
then you unvac it with "unvac vacfile
2009/0311/yourtree/thefileyouwant", unvac dies with a segmentation
fault. Apparently unvac creates the 2009 directory, but with r-xr-xr-x
permissions, so it is not able to write to it. You have to manually
create the 2009/0311 directory, with the right permissions, so unvac
is able to put your files there. Note that if you do not create the
0311 directory inside 2009, then you have your segfault again, for the
same reason as before. But when you have both directories, you can
extract whatever you want without problems ;-) (really neat stuff,
venti and its friends).
Maybe I can send a patch for this, but I am not sure if my programming
skills are good enough to start sending code to plan 9.
Saludos

Well, I've checking out the code and I am really unable to fix the
bug. It turns out that for some reason, VacDirEnum *vde inside unvac
gets the wrong permissions for 2009/0311, since it writes it with 0555
instead of 0755, when starts to walk the file tree.
I hope someone can fix this.
Saludos
