[tw] Re: Weird error

2015-04-29 Thread PMario
Hi Alex,

It would be nice to know your OS, Browser + Version, TW Version. Do you use 
TiddlyFox with FF? How big is your TW - file size.

Did you install any new Browser AddOns or Browser Apps? ... If so just 
disable them and try again.

Hi Mario,

 It would be nice to know your OS, Browser + Version, TW Version. 

Yeah, sorry, I should have thought to provide that information.

So, let's see... I'm running a linux box (KDE on Mandriva). I typically use 
Firefox (an old version, admittedly, 10.0.5, but as I've said other tiddly 
files work fine so I'd be surprised if this was the issue).

As for TW, it's a somewhat old version as well (and a modified one). Quoting 
from the relevant 'AboutTWW' tiddly:

Tiddlywiki Write (updated 11-22-10) is an implementation of the Tiddlywiki 
concept (version 2.6.1) and is an experiment in mind mapping for writers.

 Do you use
 TiddlyFox with FF? How big is your TW - file size.

I don't use TiddlyFox (first time I even hear about it, heh).

Regarding size, ah, well, that's another thing ;-) The file is fairly large, 
7.5 MB.

 Did you install any new Browser AddOns or Browser Apps? ... If so just
 disable them and try again.

No, not that I can think of. And that's perhaps the most puzzling of all :-o

It may be the file size, though, that is causing the problem. The other file I 
tested with yesterday was much smaller. I just tried with another large one 
(7.9 MB) and the first time I tried to save, nothing happened. The second 
time, Firefox crashed.

Then again, I had a lot of tabs open and I've noticed before that FF (this 
version anyway) can be a bit unstable with too many open tabs.

Thing is, now that I've restarted FF, I can save again just fine :-o

Very weird.



Alex.

good :)

--- some side notes.

Older versions of firefox had a reported problem with memory leaks. .. a 
long time ago. They worked hard to find and fix them ... 
There is a special URL that you can try:about:memory

If this URL doesn't show anything with your browser, it may be a version 
that may still have these problems. eg: with many tabs open and FF running 
for a very long time.

Still wondering what caused this, though.

Are there known issues linked to file size? If so, this could happen again and 
even possibly get worse, so it'd be good to know...

How large can I allow a TW to grow?



Alex.

I was writing about old  FireFox issues. Not about TW problems. 
 

 How large can I allow a TW to grow? 


There have been some tests with big embedded images, where the TW file was 
50+MByte. It was slow but worked using latest FF. 

I did some tests with 20.000+ tiddlers. File Size 20MB and up. Performance 
info was with my old single core 2 threaded Notebook. 

see: 

[1] 20'000 tiddlers
https://groups.google.com/forum/#!msg/tiddlywiki/E9DMg4ZTccw/P1qjS_-HOjAJ

[2] 100'000 tiddlers
https://groups.google.com/d/msg/tiddlywiki/sH4EZukozdM/PM4P3Iy_iWoJ

I did the [1] test just now with 40.000 tiddlers and with my actual 
computer it saves just fine. 46MB file size. It isn't convenient to work 
with, but it shouldn't crash the browser. 

have fun!

Nice!

Very interesting stuff.

Thank you for those links. And for your assistance ;-)
