The availability bar showed the guests it had free/busy for and quietly
left out the ones it did not. In one row that is survivable. As a grid it
would be a lie: a row with nothing in it reads as a diary with nothing in
it, and "we cannot see this person's calendar" is the one thing that must
not look like "this person is free".
So everyone the event concerns now gets a row, and the ones with no
free/busy to read are drawn hatched rather than empty, with a line under
the grid saying how many and why. You get a row too, first. Scheduling
around the other people and not around yourself is how two things end up
at the same time, and the organiser was the one calendar the panel never
showed.
Your own row is never unknown. Where the directory does not list you under
the address your identity sends from -- an alias, a login that differs
from the address -- the account is still yours to read, and Stalwart
answers for it under the account's own id.
The window steps backwards and forwards a screenful at a time without
touching the event, which is the "movable forwards & backwards" the report
asks for, and offers its way back when you have wandered off.
And the bars are somewhere to put the event rather than only something to
read: the pointer shows the half hour it is over, and a click moves the
event there keeping its length. Clicking while stepped away moves the
event to where you clicked and returns the view to it, so it lands where
you were looking instead of jumping.
Free/busy is answered per principal, and only the server's own accounts
are principals. Somebody at another domain has none to read -- which is
not a gap to be closed, it is what the protocol can see -- so the grid
says so rather than drawing them blank.
Closes#172
The bar was a day wide whatever it was drawing. It began at midnight on
the event's start day and stopped 24 hours later, so an event running over
two days showed availability for the first of them and gave no sign there
was more. And it carried no marks at all, which left "is this the whole
day or only working hours" unanswerable without dragging the event about
to see where its own outline moved.
It now covers whole days from the day the event starts to the day it ends,
and the free/busy lookup asks for the same range it draws. Above the bars
is an axis: hours every three across a single day, every six across two,
day names beyond that. The marks are drawn down the bars too, so a busy
block can be read against the hour it starts at rather than guessed at.
Whole days, always. A bar starting at the event's own start time would
move under the reader every time they adjusted it, and "busy from about a
third of the way along" is not a time anybody can read.
A week is as far as it goes. Something running longer is not an event
anybody is hunting a free slot in, and a month at eight pixels a day would
say nothing; it says how many days it left out instead.
The span is measured between two real midnights rather than counted in
24-hour days, because twice a year they differ, and every position on the
bar is a fraction of it.
The mock answered with a single busy block on the first day whatever range
it was asked for -- all a day-wide bar could show -- which would have left
a multi-day bar looking like everyone was free from the second day on. It
now answers across the range.
This is parts 1 and 2 of #172. The separate multi-day scheduling view it
also asks for is still open, and needs an answer first on what to show for
participants who have no free/busy to read.
