The idea is to capture incoming real-time data to be able to
replay it later on development systems, e.g., for new development
or troubleshooting.
Issue #230.
The script bin/daily_tasks.py is intended to be run shortly after
midnight every day (e.g., via cron).
At the moment it inserts any missing LDSP / FDSP events. It can
be extended with other tasks as needed either by expanding
Datastore.run_daily_tasks() or by adding to bin/daily_tasks.py.
Fixes#223.
This defines a midnight_shots view and a log_midnight_shots() procedure
(with some overloads). The view returns all points straddling midnight
UTC and belonging to the same sequence (so last shot of the day and
first shot of the next day).
The procedure inserts the corresponding events (optionally constrained
by an earliest and a latest date) in the event log, unless the events
already exist.
Related to #223.
This script now works with the new event log.
Fixes#234. Midnight positions can be added via a cronjob such
as:
$DOUGAL_ROOT/BIN/insert_event.py -t "$(date -I) 00:00:00Z" \
-l Daily -l Prod \
"Midnight position: @DMS@ (@POS@)"
Events being created or edited via the API now call
replace_placeholders() making it possible to use
shortcuts to enter some event-related information.
See #229 for details.
This redefines augment_event_data() to use interpolation rather than
nearest neighbour. It now takes an argument indicating the maximum
allowed interpolation timespan. An overload with a default of ten
minutes is also provided, as an in situ replacement for the previous
version.
The ten minute default is based on Triggerfish headers behaviour seen
on crew 248 during soft starts.
This defines a interpolate_geometry_from_tstamp(), taking a timestamp
and a maximum timespan in seconds. It will then interpolate a position
at the exact timestamp based on data from real_time_inputs, provided
that the effective interpolation timespan does not exceed the maximum
requested.
Fixes#243.
This defines a replace_placeholders() function, taking as arguments
a text string and either a timestamp or a sequence / point pair. It
uses the latter arguments to find metadata from which it can extract
relevant information and replace it into the text string wherever the
appropriate placeholders appear. For instance, given a call such as
replace_placeholders('The position is @POS@', NULL, 11, 2600) it will
replace '@POS@' with the position of point 2600 in sequence 11, if it
exists (or leave the placeholder untouched otherwise).
A scan_placeholders() procedure is also defined, which calls the above
function on the entire event log.
Fixes#229.
This adds event_position() and event_meta() functions which are used
to retrieve position or metadata, respectively, given either a timestamp
or a sequence / point pair. Intended to be used in the context of #229.
We take the first label associated with the event (if any) and use
the label's colour for the event marker. We override the colour for
QC events and use a default value for events with no labels or if
the label does not have an associated colour.
It uses https://github.com/debug-js/debug but it is meant to be
called like this:
const debug = require("DOUGAL_ROOT/debug")(__filename);
That way the calling module's path is used as the debug namespace.
This can be used as a shortcut when requiring a module from deep
within the file hierarchy, e.g., instead of:
require("../../../../lib/db");
one can do:
require("DOUGAL_ROOT/lib/db");
