Jon Barber — Wed, 22 Jul 2009 01:46:26 -0000

wview is a unix application for the weather stations including: Davis Vantage Pro/Pro2, Vaisala WXT-510 and a Simulated Station. It obtains weather data from the station. Generates full html web sites with graphics. ftp/ssh export capability. MySQL/PostgreSQL archiving. International. Weather alarms. Data socket feed. CWOP support. Wunderground support. RSS weather data feeds. Linksys NSLU2 support. SheevaPlug support.

5.5.2 07-21-2009
--------------------

radlib version required: 2.8.3 or newer

1) Changed Vantage Pro serial initialization to remove hangup and HW flow
control.

2) Changed internal data structures to not be packed.

3) Changed SIGCHLD processing to be more robust.

wview 5.5.1 Weather System Released

Jon Barber — Sun, 14 Jun 2009 17:47:28 -0000

5.5.1 06-14-2009
--------------------

radlib version required: 2.8.2 or newer

1) Changed UV to float in LOOP structure so decimal precision is not lost.

2) Add more paranoid sanity checks for NULL archive data.

3) Remove references to "NOAA" for NOAA-style reports in HTML templates
(because it apparently isn't clear wview generated the data?!?).

4) Updated the User Manual.

5) Added more sanity checks for data converters.

wview 5.5.0 Weather System Released

Jon Barber — Thu, 14 May 2009 12:31:19 -0000

5.5.0 05-14-2009
--------------------

radlib version required: 2.8.2 or newer

1) Modified WMR9XX station init so it will exit more gracefully.

2) Removed the wviewsqld process. Exports to external database servers will now
be done through the $distro/dbexports scripts.

3) Improved NOAA initialization process so when there are no records, it doesn't
try so hard.

4) Integrated WMR9XX changes to support configurable outside channel (thanks
Kevin Cloy).

5) Split out some NULL value checks for Vantage Pro archive record reception.

6) Added more boundary tests for image generation so when the user tries to
generate non-existent sensors, htmlgend will not crash.

7) Changed wind direction graphs from line graphs to scatter graphs (thanks
Debbie Pickett).

8) Fixed errant UV conversions in the generator.

9) Changed wind direction processing so NULL values are not graphed. Modified
wind direction archive record creation for non-archive generating stations so
it is consistent with VP record creation.

10) Fixed some bucket issues from prior dual units contributions.

11) Updated the wview management site (wviewmgmt) to support network configuration
on Debian-based distributions. Added automatic upgrade support for wviewPlug
systems.

12) Enhanced the install-env make target further including setup for Debian-based
network config.

wview 5.4.0 Weather System Released

Jon Barber — Sat, 18 Apr 2009 14:32:52 -0000

5.4.0 04-18-2009
--------------------

radlib version required: 2.8.2 or newer

1) Added new SQLite3-MySQL export scripts. Added $distro/dbexport directory
to contain the script sources. Version 5.4.x will be the last release containing
the wviewsqld daemon as it is now deprecated in favor of the wview-mysql-export
script. Added wview-mysql-create script to allow easy setup of the user, database
and tables on the MySQL server in preparation for export. Archive, HILOW and
NOAA tables are exported to the same MySQL database. Updated User Manual
section on MySQL exports.

2) Added missing documentation of the default wviewmgmt password in the User
Manual.

3) Added marker file support for the archive, hilow and noaa databases so the
synchronization externally via scripts is facilitated.

4) Removed sample databases for config and archive and changed the "install-env"
make target so it generates them. This avoids platform issues of sqlite3 databases.

5) Modified wvpmond so it reads the wview-binary marker file to know which binary
name to use for wviewd. wviewd binary names are now appended with the station type.

6) Added new SQLite3-PostgreSQL export scripts. Added $distro/dbexport directory
to contain the script sources. Version 5.4.x will be the last release containing
the wviewsqld daemon as it is now deprecated in favor of the wview-pgsql-export
script. Added wview-pgsql-create script to allow easy setup of the database
and tables on the PostgreSQL server in preparation for export. Archive, HILOW and
NOAA tables are exported to the same PostgreSQL database. Updated User Manual
section on PostgreSQL exports.

7) Added vpconfig contributions from Deborah Pickett so the ISS channels can be
configured. Also adds support for setting rain collector size and wind direction
calibration.

8) Commented out SQLite3 pragma attempts to change the journaling mode. Support
for it is not consistent across SQLite3 versions.

wview 5.3.0 Weather System Released

Jon Barber — Thu, 26 Mar 2009 02:26:50 -0000

5.3.0 03-25-2009
--------------------

radlib version required: 2.8.2 or newer

1) Created new wviewmgmt site for distribution. Better site navigation, database
updates by page, a new system status page and password protection for site
pages are a few of the enhancements.

2) Added support for a new configure environment variable, HTTP_DOC_ROOT. When
defined prior to invocation of the configure script, the install-env target
will install wviewmgmt to the http document root specified.

3) Updated the install-env target for wview build so the $prefix/var/wview/archive
directory is NOT replaced, but rather updated. This means your existing archive
database should be preserved and will not require a manual copy from the save
directory after the installation.

4) Modified HILOW database population so that archive records are now always added
as a sample (except for cumulative sensors rain, ET and hail). This avoids the
missing of the high wind value in the archive record and LOOP data during the
interval not catching the high wind value. This only applies to Vantage Pro
stations.

5) Changed initial start of sync timer so it cannot inadvertently track with the
archive interval timer.

wview 5.2.0 Weather System Released

Jon Barber — Thu, 12 Mar 2009 16:25:36 -0000

5.2.0 03-12-2009
--------------------

radlib version required: 2.8.2 or newer

1) Changed station build procedure so all station binaries are built with unique
names such as wviewd_vpro, wviewd_wxt510, etc. Modified the wviewmgmt and
wviewconfig configuration utilities to populate the file
$prefix/etc/wview/wview-binary with the appropriate wviewd binary name;
changed all start scripts to use the contents of this file when starting.

2) Moved the ConfigForms directory out of $distro/examples to $distro/wviewmgmt
and added automake logic so it is aware of the install prefix and opens the
wview-conf.sdb file directly (no soft link required). Added the ability
(with sudo membership for the http user) to start and stop wview from the
Management web interface.

3) Moved NOAA data from the ASCII file noaa.dat to an SQLite3 database,
wview-noaa.sdb. Modified NOAA generation to use the new API. See the User
Manual for a schema description.

4) Added email alert notifications. Added configuration support in wviewmgmt
and added new config parameters to the example wview-conf.sdb database. See
the UPGRADE file for instructions. Sendmail and sendEmail packages are required.

5) Added All Time html tags and sensor support. Added new tags to the almanac
template examples.

6) Fixed a bug in VP LOOP data reception logic which caused UV samples to be
a factor of 10 too large.

7) Fixed a bug in html generation caused by old DST code that pre-dated the new
SQLite archive database and the use of unix time for the records.

wview 5.1.3 Weather System Released

Jon Barber — Tue, 03 Mar 2009 22:13:05 -0000

5.1.3 03-03-2009
--------------------

radlib version required: 2.8.2 or newer

1) Added hilowcreate to the distribution - it was erroneously left out of the
prior two builds.

wview 5.1.2 Weather System Released

Jon Barber — Tue, 03 Mar 2009 15:21:44 -0000

5.1.2 03-03-2009
--------------------

radlib version required: 2.8.2 or newer

1) Fixed a bug for Vantage Pro stations which only occured if there were no
records in the wview-archive.sdb database (new install) which caused the
wviewd daemon to never retrieve archive records because of a bad
LastArchiveTime value (retrying archive record...).

wview 5.1.1 Weather System Released

Jon Barber — Sun, 01 Mar 2009 22:59:34 -0000

5.1.1 03-01-2009
--------------------

radlib version required: 2.8.2 or newer

1) Added an out-of-band utility to create the HILOW database so that limited
power platforms like the NSLU2 can create the new database while the older
version continues to archive data and generate files from templates. See
the UPGRADE file for full details on the process.

wview 5.1.0 Weather System Released

Jon Barber — Sun, 01 Mar 2009 14:53:08 -0000

5.1.0 03-01-2009
--------------------

radlib version required: 2.8.2 or newer

1) Added new HTML/Javascript/PHP forms for wview configuration. They are found
at $distro/examples/ConfigForms. That entire directory should be copied
to your web server document root. The entry point is
/ConfigForms/wview-form.php. Hooks were included for parameter value checking
but for now whatever you enter is what gets put in the wview-conf.sdb database.
A link to $prefix/etc/wview/wview-conf.sdb must be placed in the /ConfigForms
directory with proper rw permissions.

2) Added new database to store HILOW data, wview-hilow.sdb. Hourly highs and lows
are stored along with timestamps for the events, an accumulator and the number
of samples included (average = accumulator/samples). There is a separate table
for each sensor type and one record per hour is maintained from the beginning
of archive records to the current time. sensorstore.bin is no longer required.
This will also allow for implementation of all-time highs, lows and averages
in the near future. Note that the initial creation of this database will occur
the first time wview runs and will take some time according to how far back
your archive records go.

3) Fixed bug in computed data utility for archive records which was still using
the old WLK 0-15 wind direction scheme for a validation check.

4) Fixed a 1 second delay in file generation introduced when the pre/post generation
zombie bug was fixed.

5) Added more checks to the station time sync routine so time syncs are never
done at the top of the hour.
