Fix PDK Mounts

2010-08-21T01:24:45Z

Bsiegel:

PDK apps currently leave mount points open after they exit. This can lead to having many more open and mounted filesystems than expected:

</source>

A solution is to run a shell script that will search for these mount points and remove them:
<source lang="bash">
#!/bin/sh
for i in $(mount | grep 'jail' | sed 's/.*$\/var\/palm\/jail\/[^[:blank:]]*$.*/\1/'); do umount ${i} 2>/dev/null; done
for i in $(mount | grep 'jail' | sed 's/.*$\/var\/palm\/jail\/[^[:blank:]]*$.*/\1/'); do umount ${i} 2>/dev/null; done
</source>

The operation is intentionally performed twice because the /var/run/dbus mounts must be unmounted after all the other ones.

Patch Launcher Reset Scroll on Page Change

2009-08-21T21:52:05Z

Bsiegel: Initial commit

{{template:patch}}
==Introduction==

If you have many apps on a page, you may have to scroll to see some of those. The launcher maintains the scroll state (the amount you have scrolled) on each page, which means when you return to a page, you are still at the location that you last scrolled to. This can be annoying. For example, it can make it difficult to train your muscle memory because, when repeating the same steps, the app you want is not always at the same location on the screen. This patch resets the scroll of each page back to the top when it goes out of view.

==Editing Process==

* SSH in.
* Remount the filesystem as read/write:
<blockquote><source lang="bash">
sudo rootfs_open -w
</source></blockquote>
* Load launcher-assistant.js in vi:
<blockquote><source lang="bash">
sudo vi /usr/lib/luna/system/luna-applauncher/app/controllers/launcher-assistant.js
</source></blockquote>
* Locate the onPageChange method around line 157:
<blockquote><source lang="javascript">
onPageChange: function(event) {
this.activePageIndex = event.value;
this.updatePageIndicators();
},
</source></blockquote>
* Add the four lines below so that onPageChange now looks like the following:
<blockquote><source lang="javascript">
onPageChange: function(event) {
var scroller = this.getPageScroller();
if (scroller && scroller.mojo) {
scroller.mojo.revealTop(0);
}
this.activePageIndex = event.value;
this.updatePageIndicators();
},
</source></blockquote>
* Save the file and quit vi.
* Remount the filesystem as read only - this should reboot your Pre:
<blockquote><source lang="bash">
sudo rootfs_open -w
</source></blockquote>

==Patch Process==

The patch should soon be located in the webos-internals gitorious repository. Until then, you can copy and paste the source below. Visit [[Applying Patches]] for info on how to use it. To apply the patch, follow the instructions above, and after remounting the filesystem as read/write, do the following:

* Apply the patch (In this example, I have the patch file located in my home directory under '''patches'''):
<blockquote><source lang="bash">
cd /
sudo patch -p0 --backup-if-mismatch < ~/patches/reset-scroll.patch
</source></blockquote>
<blockquote>
This is what you should see if it ran properly:
<source lang="text">
patching file /usr/lib/luna/system/luna-applauncher/app/controllers/launcher-assistant.js
</source></blockquote>
* Remount the filesystem as read only as described above.

Accessing Linux From Windows

2009-07-20T17:34:13Z

Bsiegel: /* Preparation */

= Using Novaproxy to Gain Root Access on Windows =

If you are using a mac, follow the instructions here instead of this page.

Procedure:

This procedure works as is with Windows XP or Vista, and can be made to work with Windows 7 by manually installing Novacom as described on the Novacom and Windows 7 page. Using an XP virtual machine (VMware or Windows 7's "XP mode") has been reported to work if you do not have a supported platform.

Estimated time: 30 minutes depending on experience - including Next Steps after obtaining access.

== Preparation ==
* Download the [http://palm.cdnetworks.net/staging/rom/webosdoctorp100ewwsprint.jar webOS image].
* Change the file extension from .jar to .zip and then extract the archive.
* Run the driver installer from the extracted file by browsing to the folder webosdoctorp100ewwsprint/resources/ and running NovacomInstaller_x86.msi (for 32-bit Windows) or NovacomInstaller_x64.msi (for 64-bit Windows).
* Download Putty.exe from [http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html]. Note that there is no installation, you're simply downloading an exe you will run. Note where you downloaded it.
* Download and install Python 2.6 from [http://www.python.org/download http://www.python.org/download]. Make sure it's not a more recent or an older version - it must be 2.6.x!
** Install using all the default choices.
* Get a copy of the novaproxy.py script from [http://github.com/asedeno/novaproxy/raw/master/novaproxy.py http://github.com/asedeno/novaproxy/raw/master/novaproxy.py] (Right click and Save the file where you are going to remember you put it).

== The actual process ==

* Type in the Konami code on your Pre (upupdowndownleftrightleftrightbastart) to access the Developer Mode application. A blue developer icon will pop up on the Pre <div style="float:right;">[[image:DevMode.jpg]]</div>
* Open the Developer Mode application on your Pre and enable the Developer Mode switch, resetting the device when prompted.
* Connect the Pre to your PC using a USB cable. Choose the option to "Just Charge". Windows should see a new device called Palm Novacom and automatically install the drivers for it. If you are asked to locate the drivers yourself, they are in C:\Program Files\Palm, Inc\novacom\x86 (for 32-bit Windows) or C:\Program Files\Palm, Inc\novacom\amd64 (for 64-bit Windows).
* If you installed Python with all the default choices, you can simply double-click the novaproxy.py file to start Novaproxy. Otherwise, bring up a command prompt window, cd to the location in which you extracted the zip file, then type python novaproxy.py to run the script.
* The script will execute and provide further instructions. If it tells you it's listening on a localhost port (usually 8023), everything is working. Be sure not to close this window.
* If the script does not work, or tells you there is a problem and the provided instructions don't help, join our IRC channel (irc.freenode.net #webos-internals) and feel free to ask for help.
* Run putty.exe
* In PuTTY's Host Name box, type localhost and select a connection type of RAW. In the Port box, type the port that Novaproxy says it's listening on (usually 8023).
* Click on Terminal in the treeview on the left, and under Line discipline options, set both Local echo and Local line editing to Force off.
* If you want to save these settings so you don't have to set them again later, click on Session in the left treeview, enter a name for your saved connection (such as "MyPre") in the Saved Sessions box, and click the Save button. The next time you want to connect, start Novaproxy, then launch PuTTY and double-click the saved connection.
* Click the big Open button. Novaproxy should indicate it is connecting, and PuTTY should show a root prompt that looks like this:
:: <code>root@castle:/#</code>

Congrats, you are now in as root. Tread lightly.

==== Now please visit the [[Next_steps|Next steps]] after obtaining Linux Access page to see what you can do. ====
Orr type exit at the root prompt to disconnect. PuTTY and Novaproxy will both exit automatically.
