sorry, i have no good ideas. is it logging you out (back to the character selection screen), or is it actually giving you a "disconnected from server" message and making you log in again from scratch?

Disconnected from server. :(

Posted By: brykrysJust a thought - check the settings for the ScanFinish module, and see if you have the "Log out when scan complete" option enabled; although that is only supposed to log you out after a full scan, some people have been reporting oddities with that module.

Not enabled :(

Maybe you'll suggest me, how can I debug this? I know LUA a little, but not embedded into WOW. And I don't know, what debug abilities present. Can I do "coredump" by some way?

Well, same for me. Just logs me out, whenever I use search UI for several, but not for all items. Also, doing a "refresh" on an item in appraiser, disconnects for some items too, but not for all. It seems it's related, and happens on rescan for that item.
I'm playing on russian realms. And serching (manually typing) for item that otherwise disconnects works. Not sure what it is ether, russian version of wow allow to to type up to 31 char in search field, and russian names for items usually longer than english version, if it matters. Maybe it just a coincidence, but logouts happens on items with long names.
Anyway, if there is anything I can do to help investigate this issue... just name it.

Well as for "refresh" button issue, I was searching for items that on my backpack, so it's seen by the server and my client. As for SearchUI, I do it after AH scan, searching for items to disenchant, it isn't rare, ordinary craft junk seen by server and available to buyout.
Already tried both, versions of auctioneer release and beta. Both have the same issue.

For example, I have 3 items in my backpack:
[Чародейский кушак] itemid 8291 (refresh works)
[Клинок Измерений со знаком медведя] itemid 15219 (refresh isn't working)
[Мятый бархатный плащ с меткой волшебника] itemid 36409 (refresh isn't working)

It just display "Refreshing view of [itemname]" and then disconnected from server

Checked every other item in backpack, eg reagents, etc... refresh works ok. Just this two items, i'll keep them for a while for testing purposes.

itonohito, which locale do you have?

Posted By: Janikeitonohito, which locale do you have?

Russian too. :)

AucAdvanced has had the groundwork for localization done, and will be in the next release (and is already in the Preview builds)

However, we need your help in localizing.
If you go to http://localizer.norganna.org, you can help us enter in proper translations. At the moment, the russian (ruRU) locale is only 44% complete for Auctioneer.

Well, HNY to all!

Sorry, no news for some time. I've been quite busy last weeks, spending holidays with my family and the kids.
To the point, I was able to dedicate some time to this problem and found the source of it.

Disconnect happen when we call original WoW API function via
"private.Hook.QueryAuctionItems" with invalid name parameter.
Name parameter have limit on the length of a string that we can pass
to it and seems like it is limited to 63 bytes. Disconnect only happen
when we pass invalid utf8 encoded string.
This is happen only on russian realms because item names in russian
encoded using 2 byte character codes and are usually longer than 30
characters, resulting in a string larger than 63 bytes. If game then cut that
string to 63 bytes, we have big chances to hit it in the middle of a
2 byte character, resulting in invalid encoded utf8 string and
get disconnected from the server.

I have traced my problems to 2 function calls in CoreScan.lua script
and successfully worked around them by using the following code:

in function lib.ScanPage on line 904 before calling "private.Hook.QueryAuctionItems"
I've added some code to trim name argument to 60 bytes, ensuring that
no control character left at the end of a line:
local name = private.curQuery.name -- make a copy of name (dont forget to use it in actual call to private.Hook.QueryAuctionItems)
if (name and string.len(name) > 61) then -- check name for long utf-8 strings
name = string.sub(name, 1, 61) -- strip it off
if (string.byte(name, 61) >= 192) then -- check last byte for utf-8 start code
name = string.sub(name, 1, 60) -- ugly code to strip last byte
end
end

same code was added to wrapper function QueryAuctionItems on line 1264
just before queuing call to "private.Hook.QueryAuctionItems"

After applying such hack I have no disconnects in about 2 weeks of
testing and everyday playing.

I hope core developers can use this information to fix disconnect
issues in main code. I have little knowledge of Auc-Advanced internals, and my code
far from being perfect with possible side effects :)

I was using AuctioneerSuite v5.1.3935 in my testings.

Well, I suppose Blizzard could, and in theory even should, fix this issue. Good API should not trigger disconnects this way, it should report an error if it receive bad arguments to it's functions. There should be no problem increasing limit from 63 bytes to something more adequate, considering support of utf 8 and long item names in localized versions. If we couldn't type full item name in search box, it's already a bug, maybe not critical, but a bug...

For English and other clients that use single byte characters it's not really a problem at all, item names never reach this limit and won't trigger disconnect. But since I switched to Russian realm, I triggered this bug almost instantly in a worst possible way. This bug renders almost all Auctioneer advanced features useless, especially SearchUI. So my point of view, if we aware of this bug happening and we could easily work around it, we should do it. And If Blizzard fix this in later patches, we could clean up the code.

I suppose this or preferably better code could be wrapped to simple function like this:
function lib.qaiPrepareName(ItemName)
local name = ItemName
if (name and string.len(name) > 61) then
name = string.sub(name, 1, 61)
if (string.byte(name, 61) >= 192) then
name = string.sub(name, 1, 60)
end
end
return name
end

And if we no longer need it, it could be safely replaced by:
function lib.qaiPrepareName(ItemName)
return ItemName
end
Or drop it all together..

Anyway, thanks for the information and the answer.

Issue moved to http://jira.norganna.org/browse/ADV-397 (same issue, different section of Auctioneer)

Janike: I took your code and modified it a bit. It's in Dev version 3967. Until it gets added to the beta version, it can be accessed at http://svn.norganna.org/auctioneer/trunk/Auc-Advanced/CoreScan.lua - see what you think
