Alerts disabled & Automatic weather report updates
Heikki Hannikainen
aprs.fi's weather report pages now update automatically, in near real
time, without full page reloads: aprs.fi/weather/IZ1DSJ
I'll do the same for telemetry pages soon if this one works out OK.
Another thing is that email alerts are disabled until I fix a bug. There's
a bug in there causing a lot of emails to go out for some recipients (in
the hundreds). :)

I was just watching a weather page and when it auto-refreshed the
data, the wind units changed from MPH to m/s and temperature changed
from F to C. My default is imperial units, and a full page refresh
gave me imperial units again.
Here is the page I was viewing:

This also does interesting things with the graph! 78 becomes 25.6,
which looks like a dramatic drop in temperature.

Ah, this gets interesting. I guess if you go to http://aprs.fi/info/OH2TI
and then select another month in "Stations heard directly by OH2TI", you
also get metric distances? There was another report for this happening to
someone.
It doesn't happen for me if I change to imperial units in Preferences, I
have tested it many times. For some reason the ajax calls done by your
browser don't find the right settings to use and go with the defaults.
Could be browser-specific.
So, again I have to ask the same old question: What browser, and what
browser version are you using? Which operating system?
I would appreciate it greatly if everyone would always specify (1) the
browser, (2) operating system, and (3) the callsign+SSID. As much
additional detail as possible. It speeds up debugging a lot if I can fire
up a similar configuration over here right away to see if it replicates
here. Replication of the problem makes fixing issues much easier! Thank
you.

No, I see miles all the time now. After reporting the problem
yesterday, I logged in and then the units were consistent again. I
changed units preferences a few times after that and always saw the
correct units.
I also tried to reproduce with a new session (incognito tab), but was
unable to get conflicting units. I always saw what was specified in
preferences.
I think somehow my original session (before logging in) had stale
preferences data, causing me to see imperial units some places, and
default units in others. I have not been able to replicate this
scenario. Do you read preferences and/or detect locale differently on
aprs.fi and aprs.fi/xml2?

Both use the same cookie which refers to a settings blob in memcache/db,
and pretty exactly the same code to get it.
It would be interesting to capture the cookies given to the service when
this happens - does the browser positively transmit the same settings
cookie for both the page request and the following AJAX call?
When you save preferences, they go in a key-value database, and the
settings key is set as a cookie. If you're logged in, they're also stored
keyed by your user account. When you log in again, it will reload the
settings by your account ID. With a couple tabs open at the same time,
this sort of issue could probably be duplicated intentionally by changing
preferences in another tab.

Pretty close to mine then. Does not reproduce easily with the released
Chrome on OS X.

Ok, I've found a reliable way to reproduce it. It is not a problem
with preferences, but rather a lack of preferences. When I start a new
incognito tab and do not set preferences, something detects my locale
and sets imperial units. When the data refreshes, it seems to not
detect my locale, reverting to the default metric units. If you are
not doing any locale detection, then there is something much more
funky happening!
1. Open an incognito tab in locale that uses imperial units.
2. Navigate to a weather graph page. See imperial units.
3. Wait for weather data update. See metric units.
1. Open an incognito tab in a locale that uses imperial units.
2. Navigate to http://aprs.fi/info/OH2TI. See distances in miles.
3. Select another month in "stations heard directly by...". See distances in km.

Ah, excellent. If you don't have settings set, it'll do a geoip lookup and
try to come up with something sensible. That should go to the cookie *and*
be used on all subsequent requests (without further guesswork), including
the ajax update for the weather data, but obviously that's not going
right. Thanks, that should be easy to reproduce and fix now, I'll just
fake my geoip result for a while. :)
I'll look at it tomorrow, it's bedtime here now.

The units bug in both the self-updating /weather/ page and the
receive/transmit month switch on the /info/ is now fixed. Small bug in how
measurement unit settings defaults were merged in the ajax updates.
