864545 - strict threading appears to be merging threads with unusual headers

Status: RESOLVED INCOMPLETE

(Thunderbird :: Untriaged, defect)

Description

[Shawn Heisey]

Attachment: jira-threading-problem.png

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:20.0) Gecko/20100101 Firefox/20.0
Build ID: 20130409194949

Steps to reproduce:

I receive a lot of mail from Apache's JIRA installation.  I have left threading at its defaults, which includes strict threading.  I am seeing messages merged into the same thread that do not belong together.  At some point in the past, I remember the messages threading correctly, but now they don't.  I allow Thunderbird to auto-update when a new version is released.  It seems as though Thunderbird is using arbitrary headers to determine threading.  Evidence suggests that the specific header in this case is X-JIRA-FingerPrint.

None of the options in the config editor look like they would fix this problem.  I looked at all options that have 'thread' in them.


Actual results:

I am attaching a partial screenshot of Thunderbird 17.0.5 for Windows.  Three of the messages have been marked in read.  All headers from those three messages are included in another file that I am attaching.


Expected results:

The messages shown in a single thread should be three separate threads.

Attachment: Headers from the three messages indicated in the screen shot.

If I type 'thread' into the config editor, all options that show up are at their defaults, and that particular config combination looks to me like it would not produce the behavior I am seeing.

Shawn, Have you seen this problem for any newer messages when using newer versions?

I'm currently on 31.4.0.

I'm not seeing the problem at the moment.  I don't know if this is because the problem doesn't affect this version, or if it's because I deleted all my *.msf files and my search index, then let Thunderbird rebuild them.  And now I can't remember what problem I was fixing when I deleted those things.  I *do* know (from watching it work) that Thunderbird had to entirely reconstruct the threading when it was rebuilding the *.msf files.

Thanks for the update.  Let's call it incomplete, until such time that data becomes available
