Updating a save-file

January 21, 2011 — BarryK
I have been away from home for a couple of days, back now and will get back onto Puppy development.

I have started to look at the code for updating a save-file when you upgrade a Puppy version.

I have been going through /etc/rc.d/rc.update, however I need feedback on what I need to look out for. If anyone reading this has a specific issue that they experienced when updating a save-file, let me know. Or, if you know where some reports have been posted in the Forum, kindly post those links.


hardcoded version numbers
Username: Jemimah
You've got version numbers in rc.update that cause probelms if someone remasters the distro and starts over on the numbering. ie: if [ $OLDPVERSION -lt 201 ];then ... It's not a specific problem with upgrading, but still something to be aware of.

testing in Lucid 5.2 development

"Upgrade a save file was tested in development of Lucid 5.2. In general programs will work, partially work,have odd problems,settings would not stay set. your mileage will very. Etc.... A discussion was started here in the development of Lucid 5.2

A few issues
Username: gjuhasz
"I always use my previous save file at upgrading. A few issues I noticed are the following (independent from which Puppy/derivative I upgrade): 1. Desktop settings partly survive the upgrade. 1a) Iconset OK, apps added OK, but the new version's icons (at their default positions) appear. E.g., I don't use the mailing feature so I always delete the mail icon, which resurrects after version upgrade. 1b) The rest of icon positions, except drive icons that I shifted upwards by editing /etc/eventmanager, are reset. E.g., I move the lock/zip/trash icons to the bottom right to make place for weather widget. After puppy version upgrade, they appear behind the weather widget. The above can be solved if I restore /root/Choices/Rox-Filer/PuppyPin from the versionupgrade folder. 2. The proprietary nvidia driver must always be reinstalled. For some reason, in spite of the nvidia driver seems to be OK after puppy version upgrade, it crashes if I visit the glx page of nvidia-settings. Also, glxgears crashes. Thus, after puppy upgrade,I always reinstall nvidia to give glx a go. 3. Some apps that I have added as pet to the old version can be included in the new one or have alternative(s) for that. I could be useful to list the concurrent packages and ask whether the user wants to uninstall the pet. 4. From my dreams :) Let's say, I have removed a built-in package from the old version. It would be nice to offer excluding the same package from the upgraded version.

Saving out of PUPMODE 77
Username: dogle
"It seems inordinately difficult to convey settings etc. accumulated under PUPMODE 77 to another installation running in, say, PUPMODE 12. is the latest of a long line of threads which thus far have failed to resolve the issue. Is it possible to introduce the 'save to file' option when closing a session running in PUPMODE 77, or is there an insurmountable technical obstacle (e.g. can't touch me, I'm part of the Union fs)? (The absence of the save to file option here appears to be the one longstanding big stumbling block in Puppy's otherwise sublime flexibility).

PUPMODE 77 to 12
Username: BarryK
"dogle, You can probably do it manually. If you open /etc/rc.d/PUPSTATE in a text editor (while running with PUPMODE 77) and change the PUPMODE line to: PUPMODE=5 Then at shutdown it will offer to save the session to a file.

Version upgrade improvements

"Thanks for the feedback guys. I have made some changes, which will be in the next build of Wary.

Help w/ Woof, plz...
Username: starhawk
"Greetings to Mr. Kauler! Sir, I really enjoy Puppy, and I'm trying to make a custom puplet with Woof. I'm having some troubles with the GUI setup and I'm too bloody stupid to use scripts (please pardon, I was raised on Windows). I've got a thread up in the Puppy forum but I'm not getting much help. It's here: I don't suppose you could drop by and help me out a bit if you have the time? Thanks!

"bigpup, No, because there are changes in the 'init' script in the initrd.gz file. A new release of Puppy is required.

PUPMODE 77 to12
Username: dogle
"Thanks, editing to PUPMODE=5 enables 'save to file' but unfortunately corruption seems to occur somewhere in the saving process,so a practical escape route from PUPMODE 77 saving-wise still remains elusive. Reports in the thread

rc.update logic issues
Username: InTheDogHouse
"Issue: save file puppypin entries superseded by original .sfs entries. Solution: change sort -u to sort -ur so newer entries with same executable will be retained and older entries will be dropped. Issue: puppypin entries with x,y coordinates, e.g., 55_32 are partial matching (grep) to other entries, e.g., 55_320, causing desktop icons to be moved when not called for. Solution: change XYLOG="$XYLOG $ONEXY" to XYLOG="$XYLOG $ONEXY " (appended one space char), and change grep "$ONEXY" to grep " $ONEXY " (for exact matching) This solved all my problems! Love Puppy Linux! Many thanx
