292778 - Moving emails to mail folders with a . (dot) in them is extremely slow

Status: RESOLVED EXPIRED

(Thunderbird :: General, defect)

Description

[gboissiere]

User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322)
Build Identifier: Build 20050317

I had a large folder (300 MB) called BR.com as a subfolder of my Inbox.

When moving emails from my Inbox to this subfolder, it sometimes (10% of the 
time) took several minutes to perform the operation, as if Thunderbird was re-
indexing the whole folder from scratch.  Same thing would happen with a rule to 
automatically move incoming emails to that folder.  Thunderbird would freeze 
for 5 minutes, and then come back up after the message was moved.

Renaming the folder to BRcom as a workaround fixed this issue and I have not 
seen this behavior for 2 weeks since I made the change, so it must be a problem 
with the . in the middle of the folder name.

Reproducible: Sometimes

Steps to Reproduce:
1. Create a subfolder called BR.com as a subfolder of Inbox and put several 
thousands message in it
2. Create a rule to move some incoming messages to this BR.com subfolder
3. Leaves Thunderbird open for a couple hours
4. Click on "Get Mail" with an email that will trigger the rule

Actual Results:  
Thunderbird froze for three minutes to move a short message to the BR.com 
subfolder, as if it was reconstructing the whole folder from scratch.
After three minutes, it was back up and working as expected.  The message was 
properly moved to the folder.

Expected Results:  
Moving the message should be instantaneous.

Renaming the folder to BRcom as a workaround fixed this issue and I have not 
seen this behavior for 2 weeks since I made the change, so it must be a problem 
with the . in the middle of the folder name.
