521605 - Message folder size does not round appropriately

Status: RESOLVED WONTFIX

(Thunderbird :: Folder and Message Lists, defect)

Description

[Erik Harris]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3 (.NET CLR 3.5.30729)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.23) Gecko/20090812 Thunderbird/2.0.0.23

My "Sent" items folder has been sitting around 1MB for awhile, and I'm noticing that Thunderbird does a very poor job of determing folder sizes.  For example, the folder contained 947KB of messages.  I sent a 101KB message, and the "Sent" folder size jumped to 2MB.  It seems that 1025KB or more = 2MB, instead of more appropriately rounding down to 1MB.

I assume the same is true for all other size boundaries, but I have not tested this exhaustively.

Reproducible: Always

Steps to Reproduce:
1. Get just under 1MB of messages in a folder
2. Add a message that will boost it to just a hair over 1MB
3. Look at new message folder size
Actual Results:  
Folder size displayed = 2MB

Expected Results:  
Folder size should be displayed = 1MB, or perhaps decimal values under 10MB (1.1MB).  However displayed, it should rounded, and not use a ceiling function.

Thunderbird 3 has removed this feature to an extension, it is planned to bring it back in a different form in folder summary pages post Thunderbird 3.

As Thunderbird 2 builds are security & stability only, this bug is therefore a won't fix.

The feature was removed?  That stinks.  However, if it's coming back in another form, and uses the same computation algorithm, won't this still need fixing?
