Consistent "It's not possible to save changes." when I didn't change anything on my end about file-backups HOT 26 CLOSED

see: https://classic.tiddlywiki.com/#%5B%5Bversion%20macro%5D%5D

Ahh. I must've removed that from wherever it shows up in the default template. That said, I'm surprised that there's no version information in any of the backstage dropdowns. (eg. "upgrade" would be a good place to tell you what you're currently on.)

you are using an older version. ... So it should work. Which OS do you use?

Kubuntu Linux 16.04 LTS (temporarily. I'll be upgrading to 18.04 LTS as soon as I've finished fixing things that broke in the move from 14.04 LTS)

That's no message from file-backups addOn. ... Is this the exact string that's shown?

It's the cantSaveError dialog from TiddlyWiki Classic itself.

I'm guessing this means that file-backups is failing to hook the save process.

Hi Mario, thanks.

The BETA is working correctly in my environment:

Linux Mint 18.3
Firefox 68.0.2
Tiddlywiki: mgsd, based on TW classic 2.5
File-backups 0.3.10, last updated 28th August 2019.

All saves are successful, no errors, files created as expected.

Which version of TWclassic do you use? ... There have been some "saver" changes too. ... So I'm not 100% sure if it is backwards compatible. ...

from file-backups.

file-backups didn't get any updates lately. ...

from file-backups.

Which version of TWclassic do you use?

var version = {title: "TiddlyWiki", major: 2, minor: 6, revision: 5, date: new Date("October 6, 2011"), extensions: {}};

...and how is one supposed to find the version number without looking at the source? I forget.

Did you disable the AddOn and then open the wiki-tab?

The addOn only activates the "save hook" at the wiki startup. ....

from file-backups.

I did test with windows 10. ... I can test with ubuntu 18.04 and FF latest .

which FF version do you use?
file-backups version?

from file-backups.

I can reproduce the error message with ubuntu. ... So I can have a closer look.

from file-backups.

Using TWc latest also has a problem :/ So it won't help to update the wiki :/

from file-backups.

When it first happened, I assumed it might have been the result of a problem I occasionally encounter which I suspect to be caused by either Tree Style Tabs or CanvasBlocker, where I had to kill the WebExtensions process to get the browser to un-freeze.

When that happens, each extension has to be disabled and re-enabled to get it back without restarting the browser, so, yes, I did try disabling and re-enabling the extension, copying my changes to clipboard, reloading the wiki, making my edit again, and then trying to save.

from file-backups.

hmmm. if file-backups is activated, you have to reload the wiki tab. Otherwise the TW save hook can't be activated.

from file-backups.

uups. ... you did reload the tab :/ that's strange. .. I'll have a closer look, since I can reproduce the issue on my ubuntu machine.

There is a difference between windows FF and *nix FF :/

from file-backups.

Good afternoon all, and thank you for the software. Just to say I also get a failure to save, for the last few weeks.

Linux Mint 18.3
Firefox 68.0.2
Tiddlywiki: mgsd, based on TW classic 2.5
File-backups 0.3.5, last updated 3rd August 2019.

File-backups was working fine until a few weeks ago, and it still works on Windows 10.

Cheers,

Hi Jim,

I did find the problem. It seems for linux system the XHR request for the local file system has been deactivated with latest FF versions. This request still works for windows systems. ...

TWc version 2.9.2 implemented a "workaround" BUT in combination with file-backups this workaround causes a different problem, because of an oversight on my side. saving with 2.9.2 on *nix systems is also broken. ... I'll try to release a new file-backups version soon.

Sorry for the inconvenience. As soon as I do have a working beta, I'll post a link here, so you can test it.

from file-backups.

Hi Mario, thanks for the quick reply and for continuing to support this very useful add on. Looking forward to testing a working beta. Jim.

from file-backups.

Sorry for the delay. It's more complicated as it looked like. ... The issue is related with changes in FF 68, that imo uncovered a bug, with path creation, which is part of TW save mechanism for ages. It was ignored by older browsers, but seems to be a "security related" problem now :/

TW 2.6.5 has a different problem than TW 2.9.2 but they are still related to FF 68 changes.

I think, I can fix both issues with small changes, that will hopefully be future proof.

Hi folks, Here's a new BETA please try and give feedback.

file_backups-0.3.10-an+fx.xpi.zip

from file-backups.

no more complains. So it seems to work now.

from file-backups.

Oh, sorry. Something came up and derailed things before I could test it and I wound up completely forgetting. I'll try to test it today or tomorrow and give a final answer on that.

from file-backups.

Yes, still working fine on Firefox 69.0.3, setup as above. Thanks for your efforts pmario.

from file-backups.

Sorry for barely keeping the "today or tomorrow" by even my own skewed day-night cycle.

It seems to work for me too though I've only done minimal testing. Here's what I tested on:

Distributor ID: Ubuntu
Description:    Ubuntu 16.04.6 LTS
Release:        16.04
Codename:       xenial

Name 	Firefox
Version 	69.0.2
Build ID 	20191002192408

thx for the feedback

Incidentally, it works on Firefox 70, released a couple of days ago. Nice.
