collection of parse errors from iCal ics files

[diemoschwarz]

Hi, coming back to importing 1000s of ics files from iCal (see #290), I had these 60 files that produced errors with ics v0.7, from which 55 don't parse with ics==0.7.2 (from pip), Python 3.10.4 on MacOS 10.14.
I managed to extract and redact them here for a collection of test cases (see also #236): failed-redacted.zip
I hope this is still interesting and relevant to you. Thanks!

There are numerous

sequence item 0: expected str instance, bool found
A VCALENDAR must have at least one PRODID

but also these errors:

Expecting end of text 
TRIGGER with no VALUE not recognized as DURATION or as DATE-TIME
Could not match input '71039402-2147483642T0000' to any of the following formats: YYYY-MM-DDTHHmm, YYYY-M-DDTHHmm, YYYY-M-DTHHmm, YYYY/MM/DDTHHmm, YYYY/M/DDTHHmm, YYYY/M/DTHHmm, YYYY.MM.DDTHHmm, YYYY.M.DDTHHmm, YYYY.M.DTHHmm, YYYYMMDDTHHmm, YYYY-DDDDTHHmm, YYYYDDDDTHHmm, YYYY-MMTHHmm, YYYY/MMTHHmm, YYYY.MMTHHmm, YYYYTHHmm, WTHHmm.

and

SSTFTY20191231T052200.ics: Multiple calendars in one file are not supported by this method. Use ics.Calendar.parse_multiple()

which is simply due to the file being empty =-)

@strobeflash would you mind running them via the code provided at #278 (comment) - afaik PRODID is a hard requirement as per the rfc so if that function works that'd leave just the malformed 710394022147483642

[strobeflash]

@introt indeed, except the empty SSTFTY20191231T052200.ics. thanks for the hint!

A dummy PRODID to handle these cases sounds reasonable, with a warning on import. What do you think?

[strobeflash]

i also created a pull requestion for the bulk import script i used for future testing.
#374

[introt]

A dummy PRODID to handle these cases sounds reasonable, with a warning on import. What do you think?

I'd personally be against it - missing PRODIDs may be among the most common malformations out there, but they're only the tip of the invalid ics iceberg. I'm honestly surprised @diemoschwarz hasn't run into any missing END:VCALENDARs or nonstandard STATUSes. If ics-py were to parse non-compliant files, it should be implemented as a separate parse function with a distinct name (eg. rfc_noncompliant_dangerous_parser_for_broken_files etc) and straight up drop invalid data instead of adding dummy entries - which seems to be the strategy used by the proprietary solutions.

[diemoschwarz]

Thanks a lot for taking care of this! I wouldn't mind either solution, as long as there is a clear and documented way for the user to specify a default PRODID, or simply a flag to provide one if missing.
FWIW, I had hacked this into icalendar_parser.py to advance with my ics files import:

class CalendarParser(Parser):
    _prodid_default = [ContentLine(name="PRODID", value="iCal")] # Hack in default PRODID which is missing from many ical ics files

    @option(required=True, default=_prodid_default)
    def parse_prodid(calendar, prodid):
      ...

Cheers!

[C4ptainCrunch]

@diemoschwarz @strobeflash and @introt thank you for investigating this. It's great news that 0.8 seems to parse everything (modulo empty ones, missing prodids and the wierd date)

FYI #278 is also talking about missing PRODID.

Edit: if this subject gains interest, it might be a good time to reopen #236 and add those 60 example there too :)
