The interesting thing here is that for affected groups, it's almost as if pan doesn't even try. Given your description, it's as if it it's using a highwater xover from some other, much more active group. WAIT!!! I just tried getting all headers for an affected group, and DESPITE the fact that it's a gmane group, gmane.* hierarchy, not carried by anything BUT gmane, and DESPITE the fact that I have gmane set to "never expire", the log said "expiring 64 headers for <group>, and the group is again entirely empty. Re-fetching all headers doesn't seem to do anything at all. ?? Maybe it's the expiration going haywire. Check to see if there's a low- use code-path where a "0" expiration is taken as literally zero days (thus, immediately), instead of don't expire at all. Actually, that might explain the cross-posting link as well, since there may be some logic that treats it differently. (Consider the case of a cross-posted message retrieved from a short-expiration server, whether one of the groups posted to only appears on a longer-expiration server. Having the message disappear from the group only on the long-expiration server at short-expiration-server time is arguably not a good thing, tho I could see it argued either way. If Charles had some code intended to deal with that sort of thing, that only applied to cross-posts...) That could explain why it hits so few people, too. It's likely that relatively few have don't-expire-at-all set on their servers. Combined with an apparent cross-posting trigger, it'd only hit certain groups for only those users with no-expiration set on at least one server. That's likely a fairly small cross-section. > 2.

But it's possible that some of the patches you applied for regular body-text need to be applied to the the sig-handing code as well -- that's what I was suggesting, not that your patches had screwed it up. Thinking about it tho, I expect Charles' intent was to not wrap the sig at all, adding it as-is, and the bug is that some of the wrapping code is applying to it anyway, when it shouldn't. Because that wasn't intended, it's doing something weird... duplicating it! Since Joe Zeff says it happened to him some time back, presumably 0.133 or even earlier, the bug must be in Charles' code, not yours. > I've been really busy lately so I haven't had time to work on pan. "Real Live" (R) has a way of doing that to people. =:^s Meanwhile, if that x-post bug DOES end up being expiration, and can be traced and fixed now, I'll be a happy camper indeed, because that bug has been bugging me since that year plus of heavy activity that started with the C++ rewrite and 0.90 and ended at 0.130 or there abouts. I'm guessing 0.120 or 0.125 or so. With that severe a bug, I didn't really think pan was ready to go stable again, much less 1.0, but what could I do, as I hadn't a clue on how to narrow it down further and I was the only one who seemed to have it? So if that's fixed, I'll be one HAPPY camper indeed, especially since that was sort of my personal blocking bug for 1.0, tho I couldn't really push it since I couldn't get enough data to even properly file a bug on it! -- Duncan - List replies preferred.
