Bugs, bugs, bugs:

registry keys left behind:

DefaultDirectory (line 234-237): It checks for Documents\Music and sets Documents\Pictures as default. Makes no sense.
WriteScreenshotDirectory (line 223-232): On every launch, it replaces the root of the target path by the current driveletter, even if the portable app hasn't moved. Say Lightscreen Portable is on your harddrive d:, but you want the target directory e:\screenshots. You don't move anything, but the launcher always sets the target directory to d:\screenshots, even if this folder doesn't exist. That's annoying. (and has been reported here too)
CheckRunning (line 249): Should check "$PROGRAMEXECUTABLE" and not "${DEFAULTEXE}"

The Qt mess. Time to put support for clearing it up into PAL (after Beta 2 I think).

The launcher for KVIrc 4 Portable handles all these entries since it's Qt as well. Hopefully they're fixed soon....

Regression

The Qt-Mess is a 1.01 regression. Version 1.00 leaves no registry keys behind.

Same Launcher

It's the same launcher as 1.0. So, it's the app itself. I didn't test it, just did a quick update because David was busy.

Portable regression. Version 1.0 uses "Qt blah blah 4.5" and the launcher handles that, but version 1.01 uses "Qt blah blah 4.6".
I say no to quick updates, especially to all Qt apps.

Right

John T. Haller

So the app itself changed, not the launcherm as I didn't update nor test the launcher. I just did a quick repack when asked by the app dev. Right or wrong, that's all I did. The other bugs you point out were present in 1.0 as well, as it's the same launcher.

I'll either not touch it until David has time. Or ditch it and just use the PA.c launcher on it when Qt handling is better baked in, because it's basically a more than partial rewrite to fix all the bugs anyway. I'll probably ditch writing out the default path and ditch all options other than splash and additional parameters, which should handle the other bugs.

[QtKeysCleanup]

With the tip of the repository of the PortableApps.com Launcher, the Qt keys should be able to be cleaned up with this INI section:

[QtKeysCleanup]
1=Qt Factory Cache 4.6\com.trolltech.Qt.QImageIOHandlerFactoryInterface:
2=Qt Plugin Cache 4.6.false

wouldn't you need quotes around that?

Everything after the = is assigned to that variable. You only need it for leading or trailing spaces, I believe.

Possible solution for registry problem

App Guy - April 27, 2010 - 10:10pm

I was having a look in the source of the launcher and noticed that it was deleting keys from "Qt Factory Cache 4.5" when in fact it should be deleting "Qt Factory Cache 4.6". I went in and simply changed the '5' to a '6'. I have not tested this but it seems that it should work.

May the Shwartz be with you

Sure that works.

Points 1,2 and 4 could be fixed within one minute.

Fix Coming

This will be fixed as part of all the apps being revved.

Point 3 will probably be a WONTFIX. Apps are meant to utilize data and settings on the same drive, not between drives.

Performance?

Bart.S

Wouldn't it increase performance? Adjust paths only if $EXEDIR has changed?

Not Really

John T. Haller

(Homepage) - April 28, 2010 - 12:49pm

It's a single write operation. And I don't think the launcher tracks path changes.

Keeping apps and data on the same drive is a universal rule with portable apps anyway, so this is really a non-issue.

PAL Update, Gord?

John T. Haller

As Gord just re-reported this (removed as a duplicate) would you like to update it to PAL and fix the bug?

Working on it at the moment.

I've sent John an update for Lightscreen that fixes this bug, along with updating to use PAL.

[EDIT] Bump - trying to clear up some old bugs. Can the revision get released?

Fixed in 1.01 Rev 2

John T. Haller

This is fixed in the new Lightscreen Portable release.
