The Definitive Analysis of App Install Limits and App Catalog Hanging

[Tikerz]

Great work! Thank you! I am now able to install applications from the App Catalog with no freezing, no memory message, and with PMS installed working with Preware.

I don't see the app in my preware...can somebody help me...I did an update feeds and went under applications but don't see the app

[Irocdaspot513]

haha never mind...found it...thanks

So, I'm a little confused about having du return a 0. Does this leave the App Catalog installer vulnerable to filling up the /var space? Or does your mod also catch that before it actually installs? Thanks.

I have installed this patch but I also can not install any more apps from the official app catalog. Could any of the other patches out the cause a conflict?
thanks for the fix. Preware is great.

Rod, here is a mod to your 'du' command so that it will only return 0 if the app catalog is running. If app catalog is not running, it will run the normal du command. What you've posted is pretty risky for anything else that depends on the du command.

#!/bin/sh
luna-send -n 1 palm://com.palm.applicationManager/running {} 2>&1 |grep findapps  >/dev/null
if [ $? == 0 ]
then
 echo "0 $2"
else
 /usr/bin/du $*
fi

I'm not sure what app catalog is sending but you might also try this..
shift
echo "0 $*"

instead of
echo "0 $2"

...this will echo all other arguments. Not sure if you need that but might be cleaner.


But even this update isn't clean. If App Catalog is running yet another app is running that depends on 'du', it will still break. This only fixes the issue if App Catalog is not running.

Is there a way to determine if App Catalog is the one calling du?

Where can I donate a buck or two to show my appreciation for this!

Although many catalog apps have underwhelmed me, I still like to be able to install and try out new stuff - WHICH I COULDN'T DO FOR MORE THAN TWO WEEKS!

Thanks again, wish I could contribute more than $$$ to this community...

Quick suggestion for the wrapper script. It would be wise to invoke /usr/bin/du once /var hits a minimum amount of room. This way the wrapper will avoid filling up /var and causing more problems than the wrapper solves.

The workaround would be an if/then at the start of the script. I haven't tested this in production for reasons I've said elsewhere.

#!/bin/sh
MINSIZE=50000
if [ `df /var |grep /var | cut -c45-50` -lt $MINSIZE ]
then
/usr/bin/du $*
else
luna-send -n 1 palm://com.palm.applicationManager/running {} 2>&1 |grep findapps  >/dev/null
if [ $? == 0 ]
then
 echo "0 $2"
else
 /usr/bin/du $*
fi
fi

(yes, I'm rusty. I haven't done hardcore shell coding in at least six years)

Thanks.

Can anyone take a look at using ps to get the process id of LunaSysMgr, and then checking to see if it is the parent of the current process to really make sure that this du invocation is being run from LunaSysMgr ?

Another update.

There is a secondary limit. Application installation is prevented when there is less than 100MiB (102400 1K blocks) free in /var.

A new version of Fair Dinkum App Limit has been released - see the homebrew apps thread about it for details.

It will remove both the "hang" and the arbitrary 64MB limit on installation of applications.

Enjoy.

....but what memory limitations (that some are experiencing) does it not fix. It does not make ALL well and good as I understand it. I am reading and reading trying to understand what I need to do.

FWIW, I have been unable to load from APP cat, update thru Preware and have recieved message about too many applications installed. I have 82% use of /var. I have been downloading homebrew apps and a few AppCat (but not many) since day 1 using PreWare WOSQI and fileCoaster. I also rooted my Pre and put in some sort of user directory if I remember correctly.

It does not fix the 100MiB free space safety net limit. That is a limit at 60% of /var for a standard device. We're working with xorg on means to move apps to /media/internal, or you can use the meta-doctor to increase your /var space to 2GB.

I had the same problem. And Fair Dinkum fixed it. Thanks, Rod.

But before installing it I looked at the size of /var. du /var/usr/palm/applications returned about 38MB. This was far below the 256MB size of /var partition and Palm's 64MB limit on total size of all applications. I even tried and deleted several application to bring the size of /var/usr/palm/applications below 32MB, 31.6MB to be exact, and then tried to install a 30KB application from App Catalog. I got the same error message "Sorry, not enough memory." df /var returned 248.0M total, 126.1M used, 121.8M free, 51% used.

As I said, after installing Fair Dinkum App Limit I could install new apps from App Catalog again. By the way, I never had problems installing apps from Preware. Just yesterday I removed all patches and the theme, then ran WebOS Repair Utility without patch/theme compatibility mode to restore all system files from WebOS Doctor 1.2.1, after that I installed about 45 patches from Preware (none for App Catalog). So, I have no idea why I had this problem.

[rwhitby]

FYI: The functionality of the Fair Dinkum App Limit package has now been incorporated into the latest version of the Package Manager Service (that's 0.9.12). Preware itself is unchanged.
