I'm using puppet 0.25.5 and just discovered two file resource bugs. I
suspect the bugs did not exist in 0.24 because the code were using that
triggers them has been the same for a long time and while it is possible we
did not notice the problem earlier, it seems unlikely as it has been
triggering failures in our automated system tests since around the time we
upgraded.
Anyway, here's the bug. In our site.pp, we have
File {
mode => 400,
}
These two resources
file { "/mnt/www":
ensure => directory,
mode => 755,
}
file { "/var/www":
require => File["/mnt/www"],
ensure => "/mnt/www",
}
result in /mnt/www being created as mode 400. My guess is that /mnt/www is
being created with mode 755 as requested, then /var/www is being created as
a symlink to /mnt/www and then (because 400 is the default mode for all file
resources) it is being chmod'ed to mode 400, which chmod's the referenced
directory. Since the file resource is creating a symlink the correct
behavior would be to call lchmod()... except Linux has no lchmod(), all
symlinks in Linux are effectively mode 777. So puppet should in fact not
call chmod() on symlinks at all on Linux. Two other things I've observed:
* Putting mode => 755 into the second file resource fixes the problem; this
must make puppet call chmod(755) on the symlink, which "changes" the
directory to its current value.
* /mnt/www's mode is fixed on the second puppet run; the File["/mnt/www"]
notices the mode is wrong and fixes it, and I guess the File["/var/www"]
symlink resource does not try to change the mode on symlinks.
In a somewhat related issue, we also have this code:
file { "/usr/src/php":
ensure => directory,
}
This results in /usr/src/php being created as mode 400. One could argue this
is not a bug since 400 is the default mode. However on its second run puppet
changes the mode on this dir to 500. So either the initial mode or the later
change is clearly a bug. :-)
I haven't tried to track down these behaviors in puppet's source and do not
know if they are fixed in 0.26.
Thanks,
Barry
