LessBackupsPlugin

[stuckagain]

I am using FF17 and TiddlyFox AddOn. However coincidentally the LessBackupsPlugin (http://mptw.tiddlyspot.com/#LessBackupsPlugin) has stopped working. Is this connected to the change to Firefox?

Help please!

Hello,

yes, that's the problem with FireFox. The plugin you mentioned uses enablePrivilege method which is unsupported in FireFox since v17 (and since v15 you can't allow this to work for new TiddlyWikis).

Basically, this is the reason why TiddlyFox was created. Jeremy said that TiddlyFox will support importing and such things too, but this will require some time.

On the other hand, the LessBackupsPlugin won't work in its current approach even when TiddlyFox supports new things because the plugin calls enablePrivilege directly instead of using some TW core functions. I guess, the "open the file" section should be rewritten, but I'm not that good with this I/O stuff (and as for now that's a general issue, as I understand), so I can't help you with recoding the plugin. Though, there's a plugin by Jon [1] which seems imports, so it can give some ideas how to fix this; but this requires digging and coding anyway..

Best regards,

Yakov.

Thanks Yakov. My coding is very poor, so it seems the solution for me is to downgrade to FF16 or try TW with Chrome. Thanks for the feedback.

I think LessBackupsPlugin was FireFox only.

According to the code, probably for FF and IE. And I suspect that it will require downgrading to FF 14 -- if with version 17 preferences.js is deleted. Though, it can probably be re-created with FF 14 and then used with FF 16.

Yea, the browser security / removing functionality issue bites us hard these days :) And using unsupported browsers imo isn't a solution for the long run.

I think it would be possible, to rewrite the plugin, to use TiddlyFox and the "core" save mechanism. But I didn't have a closer look.

LessBackups uses a first-backup-in-each-period method that avoids ever deleting files, and also avoids having to always save multiple copies, that first occurred to me in the last-ish paragraph here: https://groups.google.com/d/msg/tiddlywiki/ARBheDSfpog/p3qyDAz_ETEJ

I'm pretty sure it could work without checking save dates (by recording the last saved period in a tiddler) so in theory it could use only the core save stuff and still work.

Who's up for it?

Hi Daniel,
Nice to see, that you are still around.

I'm having a closer look now ;)
So you used the (now depricated) file access methodes only, to get the
lastModifiedTime, to calculate the expiry variable.

IMO nope, if lastModified dates are stored in a tiddler you run into
synchronisation / consistency problems. It will be very hard to do it
right (eg: copy a file from one computer to an other one, where the
tiddler is invalid). I think a backups system needs to be reliable.

So for me the solution is, to convince Jeremy, to implement a
LessBackup(ish) algorithm.

Without the whole file stuff, it seems to be pretty simple. The only
thing to do, would be a nice TiddlyFox config page to enable / disable
it.

@jeremy
IMO A TiddlyFox config page is needed anyway ;)

uups, backups are done be TW core. This was a bad idea :/ so more
thinking is needed.
