iOS: Unable to open file (which works in Kiwix elsewhere) about apple HOT 13 CLOSED

I have just tried using libzim from pypi, and I still get the problem, it seems. You can grab a small example file which shows the problem (it loads fine in kiwix-desktop, but does not in kiwix-ios) and was created with up-to-date PyPI install from https://kryogenix.org/random/fr-small-pip.zim.
(I'm quite prepared to believe that I'm creating the zim file wrong in some way! but it does open in kiwix-desktop, so it can't be completely wrong. It might be useful, if the file really is created incorrectly, if kiwix-ios gave some direction as to why the file can't be loaded, to help people who create their own zim files.)

...and that has indeed fixed it! My created zim file now opens fine in Kiwix for iOS, now that I've added language, date, and illustration.

I shall file a bug against the python libzim bindings because their example code in their README does not include these mandatory elements, but this bug can be closed, and thank you!

Thank you @stuartlangridgemmformyour issue, you should definitly be able to open your ZIM files and have a similar user experience on all versions of Kiwix.

Let me as you two questions:

• How have you created your ZIM file? With which tool?
• Do you ise Kiwix 3.4.0 for iOS released today?

from apple.

• How have you created your ZIM file? With which tool?

I used the Python bindings for libzim to create my zim file, as packaged in Ubuntu 22.04. These seem to be 1.0.0+ds-2build1, based on libzim in Ubuntu which is version 7.2.0-2build1.

I was not using v3.4.0 of Kiwix for iOS, but I have just updated to that and tried again and I have the same issue.

(I should note that I have opened a different zim file from inside the Kiwix interface and that worked, so my Kiwix installation for iOS isn't completely broken or anything!)

@stuartlangridge OK, then its looks like a bug. Would you be able to share the ZIM file, or any ZIM file suffering of the bug?

from apple.

@stuartlangridge It seems as well that you use a very old version of python-libzim, any chance you could use the latest version published on pypi?

from apple.

@stuartlangridge I rna zimcheck against your file, and I see:

[ERROR] Metadata errors:
  Missing mandatory metadata: Language
  Missing mandatory metadata: Date
  Missing mandatory metadata: Illustration_48x48@1

At this stage, I guess there is 50% chance that the rootcause of the problem is there because these Metadata are mandatory in the ZIM spec. Would you be able to set them and try again?

from apple.

Aha, I didn't know there was a zimcheck tool! Now that I know that I'll try again and verify with zimcheck, thank you.

@rgaudin @benoit74 Actually I believe this is not really normal that a ZIM file can be written without error by python-libzim if the ZIM file can not be open afterward.

from apple.

python-libzim is a wrapper. If libzim allows it, pylibzim should as well

@mgautierfr ?

from apple.

I will transfer to openzim/libzim.

Kamino closed and cloned this issue to openzim/libzim
