The file probably got set to read-only. Right-click your World 5 folder, click Properties, uncheck Read-only and click OK. |
|
|
That file is not set to read-only, but every directory is (same as all worlds from previous versions) Not sure why the directory is getting set to read-only. Anyway, other chunks work fine, it was only this one that barfed. Chris, do you lock files for read or write? My guess is a lingering file handle. |

Had a similar issue earlier, that I finally figured out. 004219 in mantis on this (can't figure out linking yet =p) Possibility: Are you running a real time virus scanner (I have Kasperkey and it dislikes AVWW)and gives this sort of error that would intermittently crop up. Setting the main .exe to a trusted file works, though I have to reset it when the game updates. Hope it helps. |

Linked from FallingStar -- does 0004219 help, GrimerX? |

Seems to be related to Live Mesh file syncing. While it is running, AVVW.exe will sometimes fail the CreateFile request due to "PENDING DELETE". I could repro this relatively easily by entering/exiting buildings. W/O Live Mesh running, I can't repro. I can't prove that it is Live Mesh -- I see it interacting with the file, but not in a way that should put the file in a DELETE PENDING state (indeed, file handle properties indicate it's not in that state in every operation up to the failed request). It may also be something running in kernel mode; I don't see anything else running in user mode (in terms of a component integrated into the callpath). I have not tried to repro with DropBox or a real-time backup solution. I did verify the real-time Anti-Malware engine access the file, but does not cause this condition. So -- up to you how you want to handle cases where other apps interfere with your file I/O. I don't know what the impact of missing a regioninterior.dat (the only file I've seen it happen with) update. |

Well -- when other programs lock files that the game is trying to write, its really a quite big problem. At the moment it's going to be causing you some instability from then on, and frankly it's also quite likely to cause you data loss such as missing a whole dungeon or similar. It could be as low-level as missing the fact that a lietenant should be marked as killed on the world map, but still. The game is rather under the assumption that other programs won't be locking the files that it's writing as it writes them. I could make that more robust, and probably should, but at the end of the day -- given the frequency it writes its files to keep them current -- something that is trying to sync them actively is a bad idea. That would at best lead to periodic bits of lag in AVWW, and also likely will lead to loads of wasted bandwidth. Backing up the files is great, but I suggest something that is run periodically, and not when you're actively running the game. For instance, I used to use Mozy Home, and now I use Jungle Disk, to back up all my stuff of that nature. It only runs at 1am or so, when I'm not actively on my computer. |

I think it's a fair assumption :-) FWIW, My scenario isn't backup -- it's just that I use multiple computers, and hate any manual process for file sync. Generally it works but I don't expect others to dev towards it. I think even something like Steam Cloud @100Mb -- while most people may not hit that limit, the audience who are most likely to hit it would be your core audience. Anyway, random thoughts from me. I'm following up with Live Mesh in the meantime, they should support this scenario properly. |

All makes sense. I also use Dropbox for some stuff, for the same reasons as you use this, but I don't use it for files that I write _that_ frequently. For live mesh, if they were able to basically make it so that they did a lock-less file copy from one folder to a shadow folder, and then did a verification of the file in the shadow folder against the full current file on your disk (also for internal consistency), they could then write the shadow folder's copy of the file at their leisure without locking any of the core files. That is how, for example, the IIS web server compiles ASP.NET websites while allowing compiling against them at any time, and it's also part of how SVN seems to work with a lot of its diffs and comparisons without actually locking the primary files during its activities. Something like that winds up using more disk space, either in general or during the diff operations, and it can also slow down the actual sync itself, but for things that are being "hot updated" while it is actively trying to sync them, that would prevent issues with the updates. |
