T15136: Fix NULL pointer exception from Calendar's homepage in some circumstances

Commits

rPdc558b5538cd: Fix NULL pointer exception in some circumstances from Calendar's homepage

Summary

After importing specific weird events, for example from Google Calendar (bleah), it can happen that the Calendar's homepage becomes broken.

This was the Exception error shown to video:

"Call to a member function getEventsBetween() on null"

It was happening since this method can return NULL:

PhabricatorCalendarEventQuery#newRecurrenceSet()

This changeset verifies this condition from the Calendar's homepage.

Closes T15136

Test Plan

I tried in my server. I've executed the syntax lint. On my local machine I was not able to run "arc diff" since it tries to connect to root@localhost for some reasons.

234	Basically I've just indented the `$recurrences = $set->getEventsBetween()` under an `if($set)`.

This looks good to me. It seems like I may have actually ran into this before and just didn't manage to upstream the fix from Wikimedia's fork.

I also tried executing yes | arc land but nothing.

I also tried the GNU version of yes that huge efficiency - https://codegolf.stackexchange.com/a/199534 but nothing.

I also tried to re-implement yes using a low-level approach, but nothing:

yesyes

As workaround it seems I need to become a Blessed Committers until I find a definitive solution to land.

228	The rest of the codebase uses `array()` instead of `[]`, but that might just be for compatibility with old PHP.

add support for PHP versions that should be nuked
