I've been experiencing this for the past couple of months...It always
happens when I click on a newsgroup to read some new messages --
suddenly the entire newsgroup will be marked as unread (4000+ messages).

Running Thunderbird 8.0 on Ubuntu 11.04.

I don't see anything relevant in the error console.

Can you look at the newsrc file for the news server and (it will be in a

When I woke my laptop up this morning, Thunderbird hit the issue described for the builds and planning newsgroups. The other three weren't affected.

Those look like the messages should all be read, not unread. The only
other place read state is stored is in the .msf files for the
newsgroups, though we're supposed to prefer/trust the newsrc file. If
you repair one of the folders (folder properties on the newsgroup), does
it fix the unread state? Doing so will cause us to redownload all the
headers, and any messages you've stored for offline use).

I don't think file sizes are relevant here.

I'm not 100% sure what "fix" is meant to mean here. When I repair one of
the newsgroups it prompts to download all headers or N headers.
Whichever one I choose, it seems to clear the state of the folder,
download the requested ones, and mark them all as unread.

I've also started seeing this. My first thought is that we've suddenly
decided to throw away the .msf files, but I clearly see the Replied

Usenet accounts (my most heavily-used ones, though), and it doesn't
happen for all of the groups. If I remember, I'll try to cover this with
a msgdb + nntp log to see if that gives any insight.

Hi,

confirming this bug in version 8, everything worked fine in the 7. In my
case, not all messages in the group are marked as unread, but "only" few
hundered +- 2 years in the history. It is not issue of all groups, but
it has some "random" behavior.

Sometimes it helps to close the TB and reopen it, sometimes I have to recall <server>.rc file from the backup to restore the right (old) state. This *.rc file is written at the closing time, so workaround can be:
1) save *.rc file when the problem arises
2) close TB
3) replace *.rc with previously saved
4) open TB again and pray (not tested 100%)

I'm able to help with solving this issue - we have local NEWS server
here, so maybe it can bring some aditional information.

I'm experiencing this on Windows 7 64-bit.  As others have noted, this
started with TB 8.  I have reverted to TB 7 as this problem makes
following newsgroups difficult at best.

Ok, experienced it on Win7 64bit, too.

I also noticed that the content of the .rc files is odd:

<news-group-name>: 1-7,10-355,357-758

Why would there be gaps in the range although I said "Mark Newsgroup
Read"? Note that win TB 7 there's just a single range for each group
from 1 to <index-of-last-message>.

I'm also surprised that this has not been given more of a priority. I am
involved with the LibreOffice project and a number of us (active
members) have also discussed this on the LibreOffice mailing lists. It
is not really good advertisement for TB's use as a Newsgroup reader. I
have switched to the LibreOffice mailing list rather than staying on
their Gmane news and hoping the fix will come in soon.

I have also used TB as my main Newsgroup reader for years as a work
tool. I am no longer using it as my newsreader as it is too frustrating
to use at this point.

I may have be forced to switch to another reader soon unless the fix
comes in.

Ben -- thanks for raising the level and nudging the devs.

Answer to comment #29:
1. There's absolutely nothing that's being written to the console on my system concerning this bug.
2. How many changes went into the TB's NNTP subsystem between TB7 and TB8? Since that subsystem appeared to be close to death for long I suspect there aren't that many? With that list at hand I suspect it should be rather easy to identify a few suspects?

I don't know a way to reproduce the issue on demand, therefore the log
file is huge.

Searching for "ERROR" in this file I can find lots of sequences like the

I'm seeing the issue with comp.soft-sys.math.scilab, which is the first ng in the displayed list. It happens also for the second listed group but much less often. Never seen the issue for the third displayed group.

Ben, when this happens to you, do you see Thunderbird re-downloading all
the messages from the server again, for the particular group? Or does it
just show them all as unread? If the latter, I would suspect that
Thunderbird was unable to read the newsrc file/read set for particular
group for some reason, and thus thought all the messages were unread.

What's weird is that no developer is seeing this, which makes me suspect
something specific to some users' profiles/system. It does not seem to
be server-dependent, if Ben is seeing it with the mozilla news server,
which is the news server devs use most.

2. This bug doesn't appear to be *caused* by a bad newsrc, but it can result in a bad newsrc.
3. Restarting Thunderbird immediately after the bug occurs may fix that occurrence of the bug (i.e., restore your original read states). If you wait enough time (>10min, I think), it ceases to be able to fix it.

IMHO the real cause is network connection loss (OS sleep, FW blocked,
tunnel closed (my case),...). Is there any special task which is done
when connection is lost except the "Could not connect..." message? This
can be the source of problems.

I tried this out and confirm it is what happens for me: in my case OS
sleep does it.  If I close thunderbird before sleep and open it again
after wake I don't get the problem.  I use sleep regularly, and it has
always worked fine until this latest version of Thunderbird.

Not all messages were unread, just a (very) large number in that group. Other groups were unaffected.
My laptop was connected to the wireless lan at that time. I did not notice network interruptions at the time.

We don't need any more "me too" comments on this bug: we already know
this bug exists, and we are currently trying to track down the causes.

Some brief updates from more accidental testing:
1. newsrcLine internally confirmed to be reset prior to the newsgroup becoming marked all read.
[Thus, the internal readset is what is getting corrupted.]
2. Some newsgroups don't get reset to just "1": I saw 1-571 as the reset value for a newsgroup (only ~400 messages with high water around 5700).
3. Inspection of nsNNTPNewsgroupList seems to suggest that the best way to trash the read set is to call nsMsgKeySet::SetLastPossible with a low value (like 1)--everything above that value gets deleted. If the highwater mark of the newsgroup got corrupted, that would almost certainly be what's causing this issue.

If the current hypothesis is indeed correct, the following should verify it:
var Ci=Components.interfaces; var folder=Components.classes["@mozilla.org/rdf/rdf-service;1"].getService(Ci.nsIRDFService).GetResource("news://news.mozilla.org/mozilla.dev.apps.thunderbird";).QueryInterface(Ci.nsIMsgNewsFolder); folder.newsrcLine + " [high water]:" + folder.QueryInterface(Ci.nsIMsgFolder).msgDatabase.dBFolderInfo.highWater

Re: "me too" -- I hadn't seen any other mention of 32-bit Linux as an

One thing to investigate:  when I see this issue show up, but the
affected group is not *entirely* unread, there seems to be some
correlation with groups where I have "killed" threads (using the 'K'
key, as for spam);  these groups also have "holes" in the newsrc file
for the message IDs masked by the "kill".  I'm not 100% confident of
this, however.

I just ran this code (using mozilla.dev.platform instead of the thunderbird one) and got the following:
mozilla.dev.platform: 1-13006,15145
 [high water]:15148

I ran it directly after clicking that newsgroup and hitting the symptoms

Judging from where the highwater mark may be set, this confirms (barring

In this exchange, the server logon "200 news.mozilla.org" is being
treated as the response to the GROUP command; when sscanf tries to
extract a number from news.mozilla.org, it fails and sets the high-water
mark to 0. The server then moves on to the next group, and again reads
the wrong data. Then, when the server downloads again for the group, it
runs the command again and finds the correct result, which results in
everything being marked as read.

By contrast, here is the good one:

So, the big question: how do I reproduce the error? The answer is
simple: create a connection when there is something else in the queue.
Normally, this wouldn't be happening, since the entire first load of the
connection process happens in the same synchronous timestep, before
anyone can load into the queue. However, we need a new event to see that
the connection was dropped--so we end up creating a new connection after
the queue has been filled.

Reliable, reproducible test

This is a reliable test that forces the issue in question (it's not a
fix yet). Debugging the issue leads to me realize that our queue
management for pending urls is full of potential problems that I would
like to fix all at once; however, I think I can fix this bug with a
simple 1-liner that should be more easily backportable to aurora/beta.

This is the quick fix that would eliminate the regression caused by bug
226890 part 8. I'll file another bug for making the URL queues more
robust in the face of connection interruptions...

But otherwise, the patch seems to behave well. I'm just checking that
the test fails w/o the patch now.

ok, I can't reproduce the test failure - we'll have to see if it shows
up on tinderbox (but it shouldn't, since those are release builds)

Based on when I last looked at it, there is a failure hidden right
before the assertion (indeed, the failure throwing past the async driver
is probably causing the assertion).

The other assertion/test failure both bienvenu and I failed to reproduce
again. I am aware that the test relies on several assumptions about how
the internal connection logic is laid out, so it could be that one of my
assumptions isn't exactly true all of the time except on my computer.
That said, I suspect the failure is solely a test issue; the underlying
fix should bring the problem back to as it existed before bug 226980
part 8.

With that in mind, the patch has been checked in:
http://hg.mozilla.org/comm-central/rev/0b709763595d

The patch has landed on the current Thunderbird trunk (or Thunderbird
12); Thunderbird 12 itself should be released around May 1 if I have my
schedules correct (12 weeks after the next uplift, on January 31).

That said, I am planning on requesting that this be backported to all of
the branches given the severity of the bug; thus, most users should see
this fixed by around January 31 at the latest.

Status in Mozilla Thunderbird Mail and News:
  Fix Released
Status in “thunderbird” package in Ubuntu:

Bug description:
  I was tracking the upstream bug report #695309 for this issue, which
  has affected Thunderbird 8.0, the version in Oneiric. The problem has
  just been patched upstream in trunk and will make it into Thunderbird
  12 when that releases (in May, presumably too late for Precise). I
  filed this bug report to make sure that the change gets noticed and
  backported to Oneiric post-haste, as it's a pretty major usability
  failing and there was no bug on LP that was tracking this upstream bug
  that I could find.
