Fair Dinkum App Limit - remove the arbitrary limit on app installation

/var/opt I'm assuming is optware?

Yes. There's bound to be stuff in there you no longer need. Especially all the quilt dependencies if you have not migrated to quilt-lite.

/var/palm Contains databases for apps. Also contains browser cookies. Which has the potential to get pretty big if you visit a lot of pages. Cookies takes up half the space for that folder on mine.

/var/log is actually on a separate partition, so cleaning it up won't free up any space for apps.

/var/palm contains two cookie databases... one is for the web browser and I'm assuming the other stores Mojo cookies. The Mojo database is much larger, almost 200k on my Pre.

I don't have a Pre yet, but supposedly this app doesn't really solve the partitioning problem.

What's wrong with you guys just using the other super simple solution??

mv /var /media/.var
mkdir /var
ln -s /media/.var /var

Three commands and then you open yourself up to like 6 or 7 GB of space... not just 270 MB or whatever the /var partition is set at.

Without Fair Dinkum, you would still be limited to 64MB, no matter how big the partition is.

Presuming you mean /media/internal (since /media itself is actually part of the / partition, and you *really* don't want to fill that, and it's not writeable by default), it's FAT32, not ext3, so permissions and more importantly symlinks don't work (and some advanced homebrew uses symlinks).

If you just want to symlink individual basic homebrew applications, there is a whole other thread for that, and it can be used in conjunction with Fair Dinkum quite nicely, as can using the WebOS Internals Meta-Doctor to reflash with a 2GB /var partition.

Next step is to determine whether the free space limit is a fixed percentage, or a fixed number of KBs free.

I'll need to webOS Doctor my Pre yet again (this time to get my 2GB /var partition back) to test that one out ...

The secondary limit is 102400 blocks free.

So, in summary, the default Palm application installation limits are:

1) At most 64MiB installed applications
2) At least 100MiB free space in /var

Fair Dinkum fixes #1. Symlinking or WebOS Internals Meta-Doctor fixes #2.

Fix for number #2 can be found:

Symlink
Symlink Applications - WebOS Internals <-- easier for me but all images will be seen in pic app no instructions for creating hidden dir are given.
Solution to App Catalog Installation Limit - WebOS Internals <--probably better solution.

And just for the record, you really wouldn't want to "fix" #2. Even if you went through increasing the partition size for /var (which I'm seriously considering) you'd still want to keep a certain amount of free space for any data that applications might save in /var

Also, one more time, you guys rock.

Agreed. Palm chose 100MiB for a reason. I didn't respect the 64MiB max limit (as I could see no rational reason for it), but I definitely respect the 100MiB free space limit. Hence, I've increased the size of /var on my Pre to 2GiB.

very good point. the two solutions listed dont 'fix' #2 the 100mb free space limit still remains. Symlink options helps you differ a lot of storage to media file system allowing you to remain with more then 100mb free space and the meta-dr much more risky if you ask me but a great option none the less increases your var partition to 2gigs so you have 1,900mb of install space for apps

Now for all the people who believe they have Fair Dinkum App Limit installed properly, but still cannot install applications, you should do the following:

1) Use Preware 0.9.4 to install the Terminal application. If you can't find the Terminal application, then your Package Manager Service installation is broken, and you need to uninstall it then reinstall it.

2) Run the terminal application.

3) Put on your highest power reading glasses.

4) Type "df" and then hit the return key.

5) Check the line which has /var at the end. If the number immediately before the percentage is less than 102400, then you have reached the free space limit.

If there is anyone left who has installed Fair Dinkum App Limit correctly, and has more than 102400 blocks free in /var, and *still* can't install applications, please speak up and we will deal with your situation next

I have Fair Dinkum App installed....my DF line reads....

/dev/mapper/store-var   253920    199608     54312  79% /var

I am unable to install The Weather Channel's app.

I used the Solution to App Catalog Installation Limit - WebOS Internals to move numerous apps. /var/usr/palm/applications went from 49.9MB to 13.8MB

My DF line now reads

/dev/mapper/store-var  253920    162816     91104  64% /var

Fair Dinkum is still installed and I still cannot install the The Weather Channel App.

FWIW to those working on debugging this, and based on the above statement, when I had Fair Dinkum installed I noticed quite a bit of lag in both the email app when opening up an email (10 seconds at times to fully open an email) and in the messaging app when attempting to view a conversation. Uninstalled Fair Dinkum and both appear to be functioning normally again, no unexpected delays or behavior.

That's because the number before the percentage (91104) is less than 102400, so you are hitting the free space limit.

Do you have a fully repeatable test case for this? It sounds quite counter-intuitive ...

If you can repeat it, we will definitely want to debug it.

I experienced significant delays launching apps with Fair Dinkum installed as well. Uninstalled Fair Dinkum, but still can't install an app from the app catalog.

Could a few people tell me what the size of their /var/luna/data/attachments and /var/luna/data/emails is?

My attachments directory is 21MB and my emails directory is 51MB. Seems kind of high, considering my 4 email accounts are all IMAP and only sync 1 days worth of email. I was hoping it was safe to delete these directories and allow new ones to be made, but no dice. If I rename one or both of these directories, my email stops functioning (even after reboot) until I rename them back. Between those two directories and other files, /var/luna/data is 80MB which just seems strange given the strict limitations of apps and that partition.

Thoughts/advice welcomed.

You rock!!!!!!

Wow! I was going to use 'fair dinkum' in an app I was busy writing - drats...

I'll reinstall Fair Dinkum and see what I can come up with.

I'm linux illiterate , but do have Terminal installed on my Pre. What do I need to do to be able to provide this information?
