Correct and simplify URLError exception handling
Julien Palard pointed out that the way URLError exceptions were
being manually cobbled into the stderr stream wasn't quite working
(thanks!), but it was also unnecessarily complicated for reasons I
don't recall now. Rip most of it out and just go with a basic
catch/error/re-raise there instead.

Make missing alert URLs non-fatal
As a more complete fix and future-proofing for the earlier mismatch
between default_atypes and the alert URLs generated for WX zones
during correlation, stop aborting and simply add a warning if a
requested alert type has no corresponding URL.
Jeremy Stanley [Sat, 25 Jul 2020 15:26:16 +0000 (15:26 +0000)]
Correct default_atypes to match what's generated
Kevin Monceaux reported a regression with the 2.4 release. Running
with the -a/--alert option and no limited --atypes or atypes
override in weatherrc resulted in a message about undefined URLs
and no normal output. This problem crept in when hard-coding alert
types in the correlator after ditching the woefully unmaintained
zonecatalog.curr.tar data source (commit
8a37edd).
Update default_atypes so that it covers all relevant non-forecast
URLs the correlate routine embeds.

Make the build reproducible
While auditing Debian's packages, Chris Lamb reported[*] that
weather-util's correlation set generation is not reproducible
because it embeds timestamps without a means to override them and
also varies by system timezone. Allow SOURCE_DATE_EPOCH from the
calling environment and assume UTC rather than relying on locale
settings when no timezones are specified.

Get correlate() working in modern Python 3
Update a bunch of the parsing for various correlation source files
to work in both Python 2.7 and 3.5+, mostly where str vs bytes and
UTF-8 encoding/decoding are concerned. This can be cleaned up
significantly once support for 2.7 is finally dropped.

Be more thorough about file copyrights
Add a copyright header to the .gitignore file with start and end
years determined from its commit history. Add copyright headers for
the current year to overrides.log and qa.log, and also add
functionality to correlate() which adds these headers from now on.
Update the copyright year on overrides.conf, which was missed in
8a37edd and later commits. All files tracked in this repository now

Caching support for URLs with port numbers
When mangling URLs of fetched data to store in the local cache, only
split on the first colon so that URLs with port numbers in them are
properly differentiated. Previously, all URLs for the same domain
name landed in a single file if a port number was included, causing
incorrect results to be returned from the cache.
Jeremy Stanley [Sun, 31 May 2020 00:24:10 +0000 (00:24 +0000)]
Use a dedicated field for cached search timestamps
Fix a cache corruption issue by using a new "cached" field to hold
the timestamp for cached correlation search results. Previously the
"description" field was being overloaded, but this could cause the
cache to no longer load because of duplicate fields.

Decode retrieved files as UTF-8 even on Python 2
Python 2.7 is likely the only Python 2 anyone is using any longer
(even that's well past EOL upstream now), and reasonably recent
versions of 2.7 it need the same decode hack as Python 3 anyway when
dealing with some retrieved content. Just get rid of the version
detection and do it under any version.

Add weather zone hkz000 for Hong Kong Observatory
Thanks to Bill Agee for suggesting the Hong Kong Observatory's

forecast text from the HTML page in which it is embedded (if anyone
finds a plaintext version published at an alternate URL, let me know

Update correlation sources

NWS hasn't been updating for many years, and add the public domain
airports.csv file from the amazing ourairports.com community. Also
update to latest (2019) USA Census Bureau location data, March 2020
WX zone information, cooperative sites list from 2018 (latest), and
regenerated active station and zone lists. Loss of the zonecatalog
necessitates directly applying various forecast and alert URL
patterns, though some which appeared unused by NWS for many years
were not included.
Clear out all old overrides, since the vast majority are obsoleted
by refreshed data, and build fresh correlation sets from the above
sources. Basically all sites have switched from HTTP to HTTPS, so
update URLs for this too.
