Error/ Crash on Download of Calendar

DiagonalArg commented 5 years ago

In my just previously reported issue I noted that one group download failed at the end due to some error. That's not in the log since I only redirect standard output and not standard error. Here is what was in my terminal at the end:

As a result it failed to get polls or something (whatever comes after the calendar). So I suggest a gentler failure might be in order.

(I wish I could help. I don't do python.)

I got this same error when I try to run this utility.

lennier1 commented 5 years ago

Does this happen intermittently, or every time for these groups? If every time, are there any public groups where it happens?

I added a try/except to the json loading, which should keep it from crashing, but I'm not sure why they're getting an unexpected format there.

Lotus907efi commented 5 years ago

It turns out that when getting the cookies through a web browser that ampersands get turned into &amp in the text of the cookie.

So for instance something like '12345-789&yrte' becomes '12345-789\&yrte'

and I believe this is causing authentication problems. So you might want to add something to the README.md file to warn others about this problem.

DiagonalArg commented 5 years ago

Ok, @lennier1, I'm still getting an error using your script, and it happens every time I run the group. (I have no "&" appearing in my cookies.) The command is:

python3 yahoo.py -ct "$TCOOKIE" -cy "$YCOOKIE" -c "$listname"

The error:

/home/user/.local/lib/python3.5/site-packages/requests/__init__.py:83: RequestsDependencyWarning: Old version of cryptography ([1, 2, 3]) may cause slowdown.
  warnings.warn(warning, RequestsDependencyWarning)

  File "yahoo.py", line 772, in __enter__
    os.chdir(self.d)
FileNotFoundError: [Errno 2] No such file or directory: ''

It then just freezes at that point and I have to ^C out of the command. I don't know if there are other groups where this happens. This one is closed. (For right now, at least, I'm focusing on the half dozen groups that we need, some very large, so I don't have a broad enough spectrum to see how common it is.)

DiagonalArg commented 5 years ago

I'm being admonished that I'm not providing enough info for the bug. I don't see that I can add anything more than that I'm running on Ubuntu 16.04 and that the group is closed and hard to get into. There are people there worried about being outed. With the link to the full output here, I'm not sure what else I can add.

If there is some debug switch or other code you want me to run, I'm willing to do it.

marked commented 5 years ago

Include the output of: python3 -V pip3 freeze

If we don't figure it out this round, we'll have to capture the output you're getting, but I think we're narrowing it down.

sorry if I made you feel admonished

@lennier1 just asked on IRC, and I let him know that the calendar does not have anything on it (at least that I can see).

I got a calendar exception for another group. Unfortunately, this one is also closed. Here is the output from IgnoredAmbiance. Not sure if it shows you anything new. I'll also run @lennier1's and add the output from that in just a bit ... [Now added below.]

Lotus907efi commented 5 years ago

Just out of curiosity, what happens if you add a calendar event to the group so the calendar is no longer empty? If you retry downloading the group then, does that make a difference?

DiagonalArg commented 5 years ago

[Note the update on my last post. I need to check if this group has any calendar events. I'll also check if a non-admin can add a calendar event.]

Oh, that's interesting ... I'm getting something totally different on this group. When I try to go to the calendar in the web interface, I get a notice: "Your access to this calendar is being processed. Please check back later."

lennier1 commented 5 years ago

OK, this commit should (hopefully) prevent the crash. You won't get the calendar of course, though it's unclear if there ever actually is a calendar when this happens.

DiagonalArg commented 5 years ago

@lennier1 - Ok, I'm still getting the error, but now I'm also getting it on an open group. When I go to the calendar on any of my groups that have calendar access (some have it greyed out), I'm seeing, "Your access to this calendar is being processed. Please check back later," but I am able to access everything else. The open group that has this issue and that is producing the error is Autism-Mercury. It was not producing this error previously, and previously I was able to see the calendar in the web interface (even if it looked like there was nothing in it).

Try this:

python3 yahoo.py -ct "$TCOOKIE" -cy "$YCOOKIE" -c Autism-Mercury

I can download the Autism-Mercury calendar with -c with no issues, and get events. Maybe just a temporary problem?

I think this bug is now fixed in master thanks to @lennier1's change being merged. Please reopen if it reoccurs.
