This week's lectures from casebasedbiostat-001 are not getting downloaded

[rpolavar]

ar All: I am able to download the lectures from the previous two weeks. Not this week. Thank you for your help. Ramana

[dgorissen]

still an issue?

[rpolavar]

Hi Dirk:

Yes. The problem continues. I think that the problem is related to long file name. Thank you.

Best regards,

Ramana

[dgorissen]

have you tried running with --trim-path?

Hi Dirk:

Thank you for the suggestion but no luck: C:\Users\rpolavar>coursera-dl -u sriramana@gmail.com -p -d c:/coursera - -trim-path casebasedbiostat-001 Coursera-dl v1.4.10 (html.parser) Maximum path length set to 257 Logging in as 'sriramana@gmail.com'...

[dgorissen]

mmm maybe 257 could still be too high a bound in some cases. Try setting max_path_len to 240 or so on line 684 of courseradownloader.py. Then rerun with --trim-path and see what happens.

[dgorissen]

Does that change fix it for you?

[rpolavar]

Unfortunately, no, it did not fix it. It was complaining that it could not trim the path. For now, I found a Perl script that could download all the lectures. This script does not organize the lectures and the other related files into folders. But, it does the trick for me. I shall get back to your program once this course is done. Thank you.

Regards,

Ramana

I'm having the same problem, but this is likely due to me downloading on a VirtualBox guest to a shared folder on the Host (Windows). The actual path is a lot longer than the downloader has access to.

I wonder if you could create a '--shortfilename' option that rather than save:

 /win/coursera/socialpsychology-001/04 - WEEK 4 Group Behavior The Good, Bad, and Ugly/06 - Lecture 4.3 The Minimal Group From Dots to Discrimination in 60 Seconds/4 - 6 - Lecture 4.3 The Minimal Group From Dots to Discrimination in 60 Seconds.txt

it would save:

 /win/coursera/socialpsychology-001/04/06/Lecture 4.3.txt

And possibly put the full names into a TOC.txt

[dgorissen]

Confirmed & good suggestion. Will have a look and fix this.

In cleaning up the code I changed the current hack to fix this. Still a hack but should crash less often. Could you test with the master branch and see if it all runs ok for you. I havent been able to test in depth yet as Im travelling so report any issues.
