The Full WoW Patching Process
(1/1)
stoneharry:
I will keep this updated as I progress. This is very rough documentation and will be written up neatly once perfected.
The WoW patching process centres around a single text file document stored on a webserver: PatchSequenceFile.txt.
This files contents looks something like this:

To begin the patching process, the client logs into WoW and a patch is sent to them (see here: viewtopic.php?f=61&t=1771) or the user launchers the launcher.
The launcher is a executable file with an attached MPQ. The MPQ contains all the images of the launcher - overwriting these images with your own will allow you to change them.
If you open up the launcher with a hex editor, there are various strings to modify. At C8830h I found the window title (something like '%s - V%s - Title', representing 'World of Warcraft - V3.0 - 12340').
At D5B80h I found the URL's for the window display (originally: http://launcher.worldofwarcraft.com/2.0/index.xml). Note any file extension will work - I found XML did not load correctly so I used a php file.
Note that you need to keep the number of characters the same to maintain file integrity. Use full stops for empty space where required to fill up, and do not exceed the number of characters you have deleted to add your content.
The results are shown below:
Note that throughout this you can find logs of what is happening in the WoW folder. This is useful for identifying what is happening.
When the launcher starts up, it is going to look at the patch list file as described earlier. Upon finding a valid update, it will download it:
--- Code: ---16:30:51.8109 Launcher version 2.1.1.1897
16:30:51.9211 Reverting to old PSF patching system.
16:30:52.3149 Fetch version information from 127.0.0.1 (http://127.0.0.1/update/PatchSequenceFile.txt).
16:30:52.3463 Received version information from http://127.0.0.1/update/PatchSequenceFile.txt.
16:30:52.3514 A game update is required.
...
--- End code ---
This will download the contents of the file you have targeted in the patch list file, and save it into wow-update.mpq inside your WoW folder. Note, this is the same result as receiving a patch through the WoW.exe as linked to earlier, and follows the same format.
Subsequently, for the patch to be installed correctly, the WoW.exe must be patched to allow unsigned patches (viewtopic.php?f=59&t=1829) and for the contents to contain a list file detailing what instructions to carry out.
My patch that is downloaded consists of two files, as does Blizzard's:
--- Code: ---prepatch.lst
BackgroundDownloader.exe
--- End code ---
The contents of prepatch.lst is:
--- Code: ---extract BackgroundDownloader.exe
execute BackgroundDownloader.exe
--- End code ---
For the BackgroundDownloader, I took Blizzard's from 3.3.5 to 3.3.5a and modified the URL's it points to. Images are again stored as an attached MPQ.
At D1D40h you can find the two URL's that need to be modified.
At this point the WoW client will download the patch:
However, when trying to execute the patch:
--- Code: ---16:57:30.3841 IPC Monitor Cancel Patch: Timeout, State = ready_downloader
--- End code ---
I am not sure why this is happening. Need to investigate it further. However, the WoW client will install it upon logging in as wow-patch.mpq exists:
Now we need to add to the patch list for the downloader:

--- End code ---
The downloader targets this torrent file and... torrents it. At the downloader start up it sends a message to the global tracker to announce it is online (these are urls:3724 in the downloader if you wish to modify). Trackers must be http to work I found from testing.
The torrent file goes in the ..background directory:
--- Code: ---backgroundWoW-3.3.5.12340-x86-Win-enGB-BKGND.torrent
updateDownloader.ini
updatePatchSequenceFile.txt

--- End code ---
Note these file locations are important (and their names).
The Downloader.ini's contents should look like this:

In the above log, I tried to use localhost as the tracker which failed (I have no idea what I am doing with torrents half the time).
Once the downloader has finished (it will download to WoW DirectoryUpdate) it will attempt to execute what it downloaded - this is being worked on here: viewtopic.php?f=12&t=4309 But you can attach any executable file if you wish.
The installer will display patch notes and move/delete/add all the necessary files. Once installation is complete, then WoW.exe will launch and the installer will close.
Now the updated WoW version with your new patches should be running. Congratulations on completely automating the patching process using Blizzard's methods and tools.
