Steps to reproduce:

Have an event in the last and prior week of the month to be printed.
For example, meetings every Tuesday and Thursday.
Print the month in the monthly grid format.
For example, October of 2021.

Actual results:

September 28 and 30 are left blank.
November 2 and 4 are left blank.

Expected results:

In the past, everything was printed. I expect to replace (on a peg-board) last month's calendar page with the new one without losing the entries in the last week of this month (or the first week of the coming month).

Note that this could lead to safety items being missed if the printed calendar is replaced during the last week of a month.

I have 91.1.1. I downloaded this because my prior version refused to open for me.

And several other annoyances:

• All views now have a title so something intelligent can be used as a file name when printing to file.
• Fix the week view where the start-of-week preference is not Monday.

It was a deliberate decision not to print the events outside the month selected. In hindsight though I think it was a bad decision, so I've reversed it.

It was a deliberate decision not to print the events outside the month selected. In hindsight though I think it was a bad decision, so I've reversed it.

Through what process are these decisions made?

The calculated last day was wrong in two ways:

• It was based on the first day after the month to be printed, so the value could be a week later than needed. This wouldn't be a problem, except that it covered up the other problem.
• I didn't add a day, so events on the last day weren't displayed. (Because the end-of-week value was 00:00 of the last day, getItems didn't return items ON the last day.)

Reopening, to fix a calculation mistake.

Through what process are these decisions made?

I think "Is this what it should do?", and then I think "Yes, this is what it should do.".

So, no real process, or user driven group driving this, just one man's personal opinion. Got it. Thanks anyhow.

Right. The man employed by the council elected by the users to make decisions like this one, so that we don't have to go through a tedious consultation process over every little thing. If you don't like the decisions I make, you can request that I reconsider them just like the reporter of this bug has done.

Thank you, Geoff Lankow (:darktrojan)
How does a user (ME) get the fix? I don't know enough to try with the code.
Updating to 91.1.2 did not include the fix.
Thanks.

Correct, the fix has only made it to our development channel at the moment. It'll go to our beta channel next week and from there I'll get it to the release channel ASAP. Probably 91.2.1 in two-three weeks. (Sorry it doesn't happen much faster than that, we have to make sure everything is safe to release before we send it to millions of users.)

[Approval Request Comment]
Regression caused by (bug #): bug 1713045, I guess
User impact if declined: some events are not printed when the user might expect them to be
Testing completed (on c-c, etc.): in 94.0b1
Risk to taking this patch (and alternatives if risky): low

There's a follow-up patch which also needs to be uplifted.

Verified fixed testing the 91.2.1 release candidate on Windows 10 when printed in Portrait mode with Scale set to "Fit to page width". Needed to set Scale on my system to 80% to get a one page print out in Landscape mode.

I am presuming this bug report was about Portrait mode.
