Download/Sync now fails w/newly subscribed newsgroup
From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:0.9.1) Gecko/20010604 Netscape6/6.1b1 BuildID: 2001060409 no messages are downloaded on newly subscribed and unread newsgroup. Reproducible: Always Steps to Reproduce: 1. In Mail/News, subscribe to a new newsgroup (ie.. 3b.config) 2. Before downloading messages, goto and select File\Offline\Download/Sync now... 3. In dialog box, select "Newsgroup Messages" to download and click the "Select.." button. 4. Select the new newsgroup (3b.config) and click OK. 5. Now, go offline and select the newgroup to read messages. Actual Results: No messages were downloaded Expected Results: All messages should have been downloaded for reading in offline mode.
yes, for now, you have to open the newsgroups to get the headers first before we know to download the message bodies.

*** Bug 86818 has been marked as a duplicate of this bug. ***
the basic fix is to make sure we download headers for the group before figuring out which message bodies to download. I had to remove some code that was added for custom headers: - nsCOMPtr <nsIFileSpec> pathSpec; - err= scopeFolder->GetPath(getter_AddRefs(pathSpec)); - PRBool exists=PR_FALSE; - err = pathSpec->Exists(&exists); - if (!exists) return NS_ERROR_FILE_NOT_FOUND; This code breaks offline downloading of newsgroups unless the newsgroup had already downloaded message bodies. I tried custom headers while offline with these lines removed and it didn't crash or anything, so I think those lines should not be there. I understand that you were trying to make this search fail if there was no offline message bodies for custom headers, but we can still do offline search with no offline message body...and downloading of newsgroup messages needs to work when there's no offline message file yet. The other fixes make it so there's a reference to the newsgroup downloader - otherwise, the ref count was going to 0 and we were crashing in some instances. I also had to make getnewmessages use the uri listener, so I could know when the url was finished running. I also used some PRBackedBools where possible.
Navin, if you could review this, that would be great, thx!
the problem was not that it was crashing but it went into an infinite loop with throbber going forever, IIRC.
oh right, I fixed that too: rv = scope->TimeSlice (aDone); if (NS_FAILED(rv)) *aDone = PR_TRUE;

thx, your point is taken about initializing rv but I thought the control flow was just complicated enough that I didn't want someone making a change that made rv be returned unitialized. if the code was something like nsresult rv= NS_OK; rv = Foo(); then I would agree 100%.
this basically works now. I'll try some more tests, but I've checked in this fix, and it seems to work.

Using commercial builds: 1-31-06-trunk win nt 4.0 1-31-08-trunk linux 2.2, mac 9.1 Verified that if you subscribe to a new newsgroup(s) and then immediatly go to download/sync now process (without first clicking on the newly subscribed newsgroups to get headers) and download those new newsgroups, the result is the newsgroups are downloaded. Will verify when I test on MAC os 10.1
using 2002020418 on mac 10.1.2 In both Modern/classic, I am able to subscribe and download a brand new newsgroup w/out first clicking the newsgrp and getting the headers. marking as verified.
