.dat file on Mail News shutdown
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.6b) Gecko/20031216 Firebird/0.7+ Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.6b) Gecko/20031216 Firebird/0.7+ The panacea.dat file can contain references to mail folders and other data deleted long ago, which no longer exist. The file and program work correctly in spite of this. Anyway, cleaning the file would be useful. It would make it smaller, thus faster. And it would show relevant data to those who like to look into it. Reproducible: Always Steps to Reproduce:
yeah, we should be doing a compress commit if possible.

>>The file and program work correctly in spite of this Actually, I would be bold enough to suggest that the file and program do not work properly, and that this should be a bug not an enhancement request. I seem to have noticed on occasion that the references to old folders does cause problems. (try importing messages from M$ Outlook on windows, restarting, and then trying to do it again). Could these be related? <a href="http://bugzilla.mozilla.org/show_bug.cgi?id=46365">bug 46365</a> <a href="http://bugzilla.mozilla.org/show_bug.cgi?id=65303#c12">bug 65303</a> Anyway.
It turns out we are doing a compress commit of the db. So the entries in panacea.dat exist in the internal folder hierarchy datastructures at shutdown time...So the problem is not with panacea.dat but with the datastructures in memory.
David, yes, because they are always loaded from the file again. The problem then is, the datastructures should have been optimized at the moment the folders were deleted. That bug 65303 (comment 12) may really have something related. Or the same cause.

And to make it more interesting, the same problem applies to other files using the mork db. I can see email addresses and names in the abook.mab file which I have deleted year ago and there are no visible cards which would contain them.
Would it be of any use for me to do some testing around the problem? I am happy to try various scenarios which may dig up some useful information. (can try on windows, linux, and mac)
I tried to delete all the cards in the addressbook. After closing Mozilla, all the data was still in the file (abook.mab). Of course, the cards were no longer visible. I tries to create cards with the same names, but no problem was found. My testing may be skewed by the fact that this profile was created with 1.3 and migrated through all versions to 1.7. Maybe 1.3 wrote something bad in the file and newer versions don't do it now. If you have some time, you can try the scenarios mentioned here. Try it with a clean profile in 1.7.2. Make some cards in address book, close Moz, start, delete them, close Moz. Are the people names still visible in abook.mab? The same can be done with mail - create a new account in this profile, make some folders, restart, delete them. Are they still mentioned in panacea.dat?
David already implemented "rebuild panacea.dat on shutdown, if a folder has been deleted" in patch for Bug 267345. See Bug 267345 Comment #14. The patch was checked-in on 2004-11-09. aceman and Ross Kendall, does poblem still remain after the patch? (In reply to comment #7) aceman, do you mean "deleted but uncleared data in abook.mab" was saved in panacea.dat in your environment? If not, that is completely different issue from this bug. (Something like "Deleted mail is not cleared until compact folder") Open separate bug for it if "deleted but uncleared data in abook.mab" caused problems on your environment.
yes, thanks m-wada, this is a dup, and aceman's issue is different. *** This bug has been marked as a duplicate of 267345 ***

Yes, it seems that that implementation may accidentally fix the problem reported here. But as we commented on it further, it may be that the problem isn't only with panacea.dat, see below. > aceman and Ross Kendall, does poblem still remain after the patch? Will check in 1.8 final... > (In reply to comment #7) > aceman, do you mean "deleted but uncleared data in abook.mab" was saved in > panacea.dat in your environment? > If not, that is completely different issue from this bug. > (Something like "Deleted mail is not cleared until compact folder") No data from abook.mab in panacea.dat, that is a misunderstanding. I wanted to say that: deleted data is still preserved in abook.mab IN THE SAME WAY AS deleted data is still preserved in panacea.dat IN THE SAME WAY AS deleted data is still preserved in mbox files BUT there is a 'compaction' operation for mbox files (folders) BUT there is no (visible) one for abook.mab and panacea.dat. So, either there is some hidden one, or it kicks in automatically (on the first quarter of the moon), or there is a bug and the data stays there forewer. > Open separate bug for it if "deleted but uncleared data in abook.mab" caused > problems on your environment. It caused no problems so far, but it is a privacy issue, atleast.
