Beta testers needed

kovidgoyal · 04-09-2019, 12:19 AM

Hi all,

I would appreciate it if some of you could beta test the next calibre release.
There is an on-going effort to port calibre to Python 3 and as preparation for that, there have been lots of wide-ranging changes to calibre internals. I have tested things and been running the ported code myself for a while now, but given how large calibre is, there is no way for me to cover everything. So beta testing by a larger group would be appreciated.

Please backup your calibre configuration folder and libraries before installing the beta.

Note that in particular the configuration file format for some calibre preferences has changed, old settings should be automatically migrated. Note
that if you downgrade from the beta to an older version the migrated settings will be ignored. However, if you then make new changes to the settings, they will not be migrated again.

Please report any issues you find either here or in the calibre bug tracker.

The betas are available from:
https://download.calibre-ebook.com/betas/

Stupid question: And the betas are Python 3? I downloaded calibre-3.40.1-x86_64.txz from the beta directory, and "debug device detection" tells me

Quote:

calibre 3.40.1 embedded-python: True is64bit: True
Linux-5.0.6-arch1-1-ARCH-x86_64-with-glibc2.2.5 Linux ('64bit', 'ELF')
('Linux', '5.0.6-arch1-1-ARCH', '#1 SMP PREEMPT Wed Apr 3 09:35:20 UTC 2019')
Python 2.7.15

Besides that, the only thing I noticed is this message in the console:

Quote:

/home/myuser/Downloads/xxx/calibre-beta/lib/python2.7/site-packages/bs4/element.py:16: UserWarning: The soupsieve package is not installed. CSS selectors cannot be used.

Problem is: some plugins I use won't work (overdrive doesn't do it at this moment, checked), so I cannot test it a lot. It starts, it migrates the configuration, it applies the virtual library, remove it... but I haven't tested much more.

calibre-64bit-3.40.1.msi in W10.
First impression: Everything in order.
We will continue informing.

kovidgoyal · 04-09-2019, 04:05 AM

No it is still python 2 and no plugins should be affected.

kovidgoyal · 04-09-2019, 04:13 AM

@beedaddy: That error is harmless, I will suppress it in the future.

jbacelar · 04-09-2019, 04:16 AM

In the E-book-viewer, the preferences have not been preserved.

Oh, that's bad, I probably missed it because I mostly use the new in-development viewer anyway. Thanks for reporting it.

kovidgoyal · 04-09-2019, 05:22 AM

Uploaded 3.40.2 to the betas page with the fix for the viewer preferences not being preserved. If you have already run the 3.40.1 beta then opent he calibre config directory, delete viewer.py.json. Then run the viewer and all old settings should be migrated.

3.40.2 64bit, Windows 10

The viewer doesn't open mobi files, gives the following error:

Traceback (most recent call last):
File "site-packages\calibre\utils\ipc\simple_worker.py", line 291, in main
File "site-packages\calibre\ebooks\oeb\iterator\book.py", line 65, in extract_book

UnboundLocalError: local variable 'strip_encoding_declarations' referenced before assignment

And the viewer window doesn't retain custom width or position, reverts to defaults every time it's opened.

kovidgoyal · 04-09-2019, 08:28 AM

The MOBI error will be fixed in the next release. As for the viewer window not retaining its position that is likely because the setting to save position was reverted to default. Follow the instructions in my previous post to retore the settings, or simply toggle the setting manually in the viewer preferences.

Yes, I already did that. No change. The font and layout preferences are remembered, but the window width and position are not. The option is checked.

Except for the Import List plugin, everything seems to be working here.

The Import List plugin is broken as it has it's own copy of BeautifulSoup that use sgmllib from calibre. That has been removed. But, changing to the calibre version of BeautifulSoup has fixed it. I have posted a beta of the plugin in it's thread for who needs to use it.

@Sirtel: I have uploaded 3.40.3 with fixes for your issues, thanks for the reports.
