308029 - Thunderbird ignores first line of mcd autoconfig (1.5 beta 1)

Status: RESOLVED INVALID

(Thunderbird :: Preferences, defect)

Description

[Richard Burkert]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.10) Gecko/20050716 Firefox/1.0.6
Build Identifier: Thunderbird 1.5 Beta 1 (20050908)

Thunderbird completely ignores anything on the first line of my mcd autoconfig
file.  The first line doesnt appear to be parsed at all, i can fill it with
garbage even and it wont cause a syntax error.  Anything 2nd line and on works.

Reproducible: Always

Steps to Reproduce:
1. create test autoconfig file in thunderbird binary directory,
displayError("line 1");
displayError("line 2");

2. configure thunderbird for autoconfig in greprefs/all.js,
pref("general.config.obscure_value", 0); // for MCD .cfg files
pref("general.config.filename", "my_test_autoconfig.cfg");

3. run thunderbird, note which error displays

4. close thunderbird, edit the test autoconfig file and insert a blank line (or
line of garbage, or whatever) at the top, and save

5. run thunderbird again, note which error displays

Actual Results:  
on the first run, the "line 2" error displays.  on the second run, the "line 1"
error displays (and after dismissing the error dialog, the line2 error displays).

Expected Results:  
the first run should have given results like the 2nd, i.e. the line1 error on
the first line should not have been skipped.

fresh install of 1.5 beta 1 on win xp sp2

I can confirm this. After half an hour of debugging and googling I stumbled upon this bugreport.

this is by design. We should make sure this is documented. We can't change this since that could break everyone who knew that the first line was ignored and put garbage there.
