calibre friday preview releases

[JSWolf]

I'm finding calibre processes left behind when I close calibre to install the latest beta. This is 9.11 that leaves the processes behind. I do not have the GPU enabled. I'm on Windows 11 25H2.

With the 9.11.104 preview version, I'm getting this error when clicking in the Favourites Menu plugin icon:

It didn't happen with last stable version, and the plugin hasn't changed in a while.

I had no trouble with Favorites menu in 9.11.103 and I cannot get anything to fail in 9.11.104. What exactly did you do when you received the error?

[kovidgoyal]

@thiago.eec I dont see any calibre code involved there. And I cant replicate it on my machine either.

Sorry, the error was caused by a plugin update not working well with Favourites Menu. I've already contacted the developer.

Since there seems to have been no information posted here about 9.15.100, it is now available from the calibre preview link ( https://download.calibre-ebook.com/preview/ ). It corrected an issue when I updated my run from source setup to include the added .avif file format which prevented calibre from running.

Ah yes, running from source without updating to the preview is currently broken thanks to avif support. The preview doesnt have anything noteworthy in it apart from fixing Economist and NYTimes news downloads.

Experimenting with this, I tried invoking 'The Economist' recipe.

Downloading and installing Camoufox happened completely silently without any notice or consent check? Will one be added?

Despite running Calibre Portable, Camoufox (and browserforge?) was installed under <user>/AppData/Local/calibre-dbin, not inside the portable install.

And it still failed, even with Camoufox. Although I would not be surprised if I was doing something wrong. I never use the News recipes.

[kovidgoyal]

Why would it need consent? You're already downloading code the recipe itself is dynamically downloaded, this is just more code, and it isnt placed in the install directories because it isnt managed by the installer not to mention that on many platforms install directories are not writeable without admin privileges.

As for the 403 that could be the bot protection detecting even camoufox as a bot, as I said in the economist recipe thread I dont know if this will survive usage by large numbers of people. Last time I tried it with eco, about 30 odd hours ago it worked.

I would imagine you are interested in testing this with FanFicFare?

It's been suggested. I'm not hugely optimistic, but I thought it was worth trying if Calibre is already using it.

Do you have any objections? Or suggestions?

No objections. Feel free to try though currently the API is not set in stone.

[un_pogaz]

About "consent", I think that the first time Camoufox is downloaded, it would be nice to have an informational pop-up about it (and if we refuse, it just abort the recipe).

If is true that Calibre download in background many thing, it alway little things (less than 1 Mo) and mostly things that the user explicitly enable.

Camoufox is different. It a invicible dependency AND it huge: ~500 Mo.
Therefore, I think it is polite to notify the user about this download, as well as its location, so that they can delete it if they want, and behave in an informed manner regarding this folder (in my case, add a exclusion rule for this folder in my sync/backup software).

[kovidgoyal]

Except that downloads can run without UI either directly via ebook-convert or in the background via scheduled job with calibre hidden. So how exactly is the user supposed to be notified, let alone asked for permission? Not to mention that most of the recipe descriptions are updated to state that they will download camoufox. And in this day and age 500MB isnt that much. calibre itself is 1GB plus IIRC a simple FTS index for a few thousand book library is multi GB. The *only* downside here is some disk space usage, I dont think that merits special permission. By that token, calibre should be asking users everytime it does anything that uses "lots" of disk space.
