Something strange in [fonts] section in config

[AGenuZ]

Windows, v.0.99.44 (but bug starts earlier)

There is something wrong in [fonts] section in config.cfg. A rt_font parameter starts dupping by adding "Sans, Sans, Sans, Sans, Sans, Sans," values in it.

Here is screenshot:

Also, if you set another font, like "Fira Sans", it dupes like "Fira Sans, Sans, Sans, Sans, Sans, Sans, 14".

This behavior may explain some lags when opening branch, if you're using non-default fonts in Windows version of CherryTree.

Several days of start&close of Cherrytree...

[giuspen]

have you manually edited config.cfg or only via the preferences dialog? If you close cherrytree, remove the line
rt_font=....
then start cherrytree, can you then reproduce the issue?

[AGenuZ]

have you manually edited config.cfg or only via the preferences dialog?
I always change fonts via preferences. And noticed this behaviour onle when backup configs with folder compare tool. But once or twice I replaced config with linux version in both directions.

Today I found that another parameter is affected "tree_font".

I suspected codepage and end of line of config, but cherrytree also makes new configs as UTF-8 and UNIX EOL.

I can't catch this bug for now. I created new config, restore old config, make several opening&closes, font changing. And it not reproduces for now. But I regulary found it when I make my regulary backups. Only on Windows.

So I continue to observe.

Ok! I've catched it!

I have opened a large base in CherryTree by several hours, while playing with a RAM-eating software (VirtualBox).
Than I closed that opened base to free RAM, and checked config...

The fun thing is the name of the font that I set last (Fira Sans), and name of the font that CherryTree appends (default - Sans).

So, for now:

1. Open large base (2,5 Gb);
2. Leave it open for a several hours;
3. Get a full RAM conditions;
4. Close CherryTree;
5. It append to a setting a value of default font.

Looks like an issue with the library but still I could sanitise/double check the fonts strings either at writing time or at reading time.
Can you confirm what would be the correct font in your case instead of "Fira Sans,Sans,Sans,....,Sans 13", is it "Fira Sans 13"?

correct font in your case instead of "Fira Sans,Sans,Sans,....,Sans 13", is it "Fira Sans 13"?

Yes, it always append to setted-up font (like Fira Sans or other) value of default font ", Sans " several times. And yes, it could append this even than default font is setted.

I think there is a memory leak in CherryTree, that manifest itself after hours of opened large base. Because it starts noticeably to lag in interface and edit. And can crash with this error screen.

And after that CherryTree doesn't have time to write some log. Only this window, and crash&close.

I think all [fonts] section parameters are affected. Now it's code_font and it's default font - monospace.

I'm confused, if you are on Windows, how could Ubuntu Mono come out in the font list?

[AGenuZ]

Because Windows has ability to add external fonts (ttf/otf) in system too.

Catched this in logs, while problem persist. And after CherryTree crashes on closing.

Also I noticed, that font resets in GUI settings. And after I change it to "Fira Sans Normal" in GUI, it's resets to "nothing" again.
