Description John Stracke 2003-02-04 01:37:40 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 Galeon/1.2.5 (X11; Linux i686; U;) Gecko/20020809

Description of problem:
I initially edited /etc/exports with vi, which, more or less by default, added a
blank line to the end.  This was fine, as far as exportfs was concerned; but,
when I later went to examine the settings with redhat-config-nfs, it crashed. 
The error output is:

Traceback (most recent call last):
  File "/usr/share/redhat-config-nfs/", line 29, in ?
  File "/usr/share/redhat-config-nfs/", line 141, in __init__
    self.exports = nfsBackend.NfsBackend()
  File "/usr/share/redhat-config-nfs/", line 31, in __init__
  File "/usr/share/redhat-config-nfs/", line 89, in parseFile
    hostname, options = string.split(tokens[1], "(")
IndexError: list index out of range

(Note that, the first couple of times I tried it, I was using it from the menu,
and just didn't get any kind of feedback at all.  I think GNOME ought to have
some sort of convention for providing error messages on programs run via menu
items and launchers.)

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Place a blank line in /etc/exports (I've seen it with the blank line at the
start and at the end).
2. Run redhat-config-nfs

Actual Results:  Error messages.

Expected Results:  A window coming up.

One-line fix

Trivial patch: treat blank lines the same as comments.

Comment 2 Brent Fox 2003-02-04 20:58:01 UTC
Patch applied.  Should be fixed in redhat-config-nfs-1.0.4-2.  Thanks for your help.

QA, please verify.

Comment 4 Peter van Egdom 2003-03-12 22:43:20 UTC
- Inserted a lot of blank lines before a valid entry in /etc/exports.
- Inserted a lot of blank lines between a couple of valid entries in /etc/exports.
- Inserted a lot of blank lines after a couple of valid entries in /etc/exports.

In all cases, redhat-config-nfs-1.0.4-3 started properly and rewrote the
/etc/exports file without blanks.

So... verified fixed with "redhat-config-nfs-1.0.4-3" on Phoebe 8.0.94.
