Issues Unpacking .azw4 in Calibre

[nix416]

Hello,

I am having issues unpacking an .azw4 ebook.

I know the ebook was deDRM'd as the Calibre debug log stated it was successful. I am unable to unpack in Calibre, receiving almost the same memory message as the other user:

calibre, version 2.65.1 ERROR: KindleUnpack - The Plugin v0.81.2:

Traceback (most recent call last): File "calibre_plugins.kindleunpack_plugin.action", line 267, in unpack_ebook File "calibre_plugins.kindleunpack_plugin.mobi_stuff", line 123, in unpackMOBI File "calibre_plugins.kindleunpack_plugin.kindleunpack.kindleunpack", line 869, in unpackBook File "calibre_plugins.kindleunpack_plugin.kindleunpack.mobi_sectioner", line 50, in init MemoryError

Following your advice on helping the other user, I downloaded Python 64 and the standalone Unpacker, but get this message:

Conversion Log

Input Path = "C:\Users\416\Documents\Calibre Library\Peter Raven\Biology, 10E, With Access Code For C (15)\Biology, 10E, With Access Code - Peter Raven.azw4" Output Path = "C:\Users\416\Desktop\Calibre Decrypted\New folder" WriteRawML = True Epub Output Type Set To: Auto-detect Use HD Images If Present = True

Please Wait ...

Error: Unpacking Failed

Here is the debug log from Calibre:

Any insight you could offer would be greatly appreciated.

Thank you,

Make sure the stand-alone KindleUnpack can successfully unpack ANY (none azw4) KindleBooks first; Just to rule out any config problems.

I would then try to drastically simplify the input path: something like "c:\book.azw4".

Also try bypassing the gui and running kindleunpack directly from the command line, if possible. You might at least get some better output to interpret that way.

[kevinhendricks]

Yes, that kindleunpack error means an exception was thrown and caught (posiibly the same memory error if you the total amount of memory in the machine is unchanged. Hopefully the command line version will give a better error message.

[nix416]

Thank you very much for your help, gentlemen.

It looks like there might be a config issue as the standalone was unable to unpack a .azw3 file.

I also did simplify the path and put both my test .azw3 file and my newly shortened priority .azw4 directly into the C:\ directory.

Unfortunately, I am not a coder like you guys and I am having some issues using the command line. I shift + right click to open a CL in the LIB folder where the kindleunpack file is located. When I run the command given:

python kindleunpack.py [-r -s -d -h -i] INPUT_FILE OUTPUT_FOLDER

I receive this error:

C:\Users\416\Downloads\KindleUnpack-080\KindleUnpack-080\lib>python kindleunpack.py [-r -s -d -h -i] C:\BIO.azw4 C:\ KindleUnpack v0.80 Traceback (most recent call last): File "kindleunpack.py", line 1016, in sys.exit(main()) File "kindleunpack.py", line 951, in main print(" Based on initial mobipocket version Copyright \xa9 2009 Charles M.

Any additional guidance you guys have would be GREATLY appreciated. Thanks gents, have a good day.

[kevinhendricks]

That error is a unicode decode error. Please try running kindleunpack with Python 3 (3.5 is the latest) not Python 2.7 as it defaults to thinking strings are ascii encoded even through the code is utf-8 encoded.

I think he did use Python 3 (according to the error message, anyway).

[pdurrant]

I think this is a problem with his machine's default character set. My guess is that his machine's default charcater set is one that doesn't contain the copyright character and so the print command can't convert the unicode character to a display character.

[dougmassay]

What would be your suggestion, Paul? I don't really feel comfortable advising someone to alter their default character set, so I'd be tempted to have @nix416 carefully remove the copyright symbols from lines 951 & 952 of the lib/kindleunpack.py file and see what happens (probably even suggest using the gui again).

It may barf again, though, if some special characters from the book's metadata try to get printed. But it might be worth a shot. There's been some changes to mobi_header and mobi_opf since the last release to hopefully handle encoding issues more robustly, but they wouldn't help this particular issue.

[nix416]

That is correct, gentlemen, I did actually use the latest stable version, Python 3.5.

The least I can say is thank you very much, the three of you for trying. I will be making a donation later this week.

Of course, I would also be grateful for any additional guidance.

Thanks,

nix416

[dougmassay]

I would try removing the copyright symbols from the two lines I mentioned above in the lib/kindleunpack.py file and see if it makes a difference. Let me know if you need more specific directions than that. I'm talking about opening the file in some sort of text editor and deleting just those two characters from line 951, 952.

You're running Windows 8 (or 8.1), right?

We probably need to make sure that missing characters from console fonts won't trip up kindleunpack.py's output (like we've done with the metadata contents in other files).

[nix416]

Doug,

Which specific characters are we talking about that need deleted? I have opened the file in notepad but am unable to distinguish line numbers.

I am running Windows 10.

Thanks,

nix416

[dougmassay]

Sorry I didn't respond to this sooner, but it's the copyright symbol. The little "c" with a circle around it. It appears in two consecutive lines near the end of the file.

print(" Based on initial mobipocket version Copyright © 2009 Charles M. Hannum <root@ihack.net>")

print(" Extensive Extensions and Improvements Copyright © 2009-2014 ")
