Raw Blame History

1.7.0 (2017-08-18)
------------------
__Improvements__
* Add Travis support to execute the extension tests ([#183](https://github.com/CartoDB/observatory-extension/issues/183))
__API Changes__
* Add new function `OBS_MetadataValidation` ([#303](https://github.com/CartoDB/observatory-extension/pull/303))
__Bugfixes__
* Fixed parentheses for obs_getdata with ids
* Fixed failing tests due changes in the data dump for some TIGER geometries
1.6.0 (2017-07-20)
------------------
__Improvements__
* The current OBS_GetAvailableNumerators is not designed with our
UI in mind so it's causing a lot of troubles and we're doing so
many hacks to fit our UI needs and the interface of the function so this
function it's a better fit for our purposes. ([#300](https://github.com/CartoDB/observatory-extension/pull/300))
* Now use the new meta table `obs_meta_geom_numer_timespan` to filter
the geometries by geometries timespan and/or numerator timespan (which
is what we get when we use the obs_getavailabletimespans) ([#302](https://github.com/CartoDB/observatory-extension/pull/302))
__Bugfixes__
* Right now we're doing INNER JOINS when we JOIN the `_procgeoms` and
the data so we end up with NULL value instead of id, NULL value. ([#298](https://github.com/CartoDB/observatory-extension/pull/298))
1.5.1 (2017-05-16)
------------------
__Improvements__
* Much improved performance for `OBS_GetData` when augmenting with several
different geometries simultaneously ([#285](https://github.com/CartoDB/observatory-extension/pull/285))
* Return the automatically assigned normalization type from `OBS_GetMeta`
([#285](https://github.com/CartoDB/observatory-extension/pull/285))
1.5.0 (2017-04-24)
------------------
__API Changes__
* Add `suggested_name` to `OBS_GetMeta` responses
([#281](https://github.com/CartoDB/observatory-extension/pull/281))
* Add `geom_type`, `geom_extra`, and `geom_tags` to
`OBS_GetAvailableGeometries`. This brings it up to spec with existing docs.
([#282](https://github.com/CartoDB/observatory-extension/pull/282))
* Add `timespan_type`, `timespan_extra`, and `timespan_tags` to
`OBS_GetAvailableTimespans` for consistency.
([#282](https://github.com/CartoDB/observatory-extension/pull/282))
1.4.0 (2017-03-21)
------------------
__API Changes__
* Allow for override of `target_area` and `target_geoms` in `OBS_GetMeta`
([#276](https://github.com/CartoDB/observatory-extension/pull/276)). This
allows the interface to work with points and sparse areas much btter.
* Allow for override of `max_timespan_rank` and `max_score_rank` on an
item-by-item basis for metadata.
* `numer_description`, `geom_description`, `denom_description`,
`numer_t_description`, `denom_t_description` and `geom_t_description` now
returned as part of `OBS_GetMeta`.
__Improvements__
* Reduced amount of simplification done on input geometries (from 0.0001 above
500 points to 0.00001 above 1000 points).
* Added tests to confirm that accurate results are returned from automatic
boundary selection
1.3.5 (2017-03-15)
------------------
No changes. Artifact to allow for data update.
1.3.4 (2017-03-10)
------------------
__Bugfixes__
* Remove erroneously committed `RAISE NOTICE` in `OBS_GetData`
1.3.3 (2017-03-10)
------------------
__Bugfixes__
* Resolve divide-by-zero errors in cases where the intersection of an
Observatory geometry and user geometry has 0 area
([#265](https://github.com/CartoDB/observatory-extension/pull/265))
* Run MakeValid on geometry's when intersecting, if necessary
([#268](https://github.com/CartoDB/observatory-extension/pull/268))
__Improvements__
* Add performance tests for multiple columns in `OBS_GetData`
* Major performance boost for `autotest.py` through the use of multi-column
`OBS_GetData` instead of separate `OBS_GetMeasure` calls for every single
measurement.
([#268](https://github.com/CartoDB/observatory-extension/pull/268))
* Major performance boost for `OBS_GetData` in cases where multiple columns are
requested. Previously, each additional column would result in a linear
slowdown, even if geometries could be reused.
([#267](https://github.com/CartoDB/observatory-extension/pull/267))
1.3.2 (2017-03-02)
------------------
__Bugfixes__

This fixes issues with Camshaft.
1.3.1 (2017-02-16)
------------------
__Improvements__
* It is now possible to obtain measures that are averages or medians over
arbitrary polygons ([#254](https://github.com/CartoDB/observatory-extension/pull/254).
* Added test point for Australian data
* `OBS_GetLegacyMetadata` now returns median and averages in cases where it is
called for measures for polygons
1.3.0 (2017-01-17)
------------------
__API Changes__
* `OBS_GetMeasureDataMulti()` is now called `OBS_GetData()`
* `OBS_GetMeasureMetaMulti()` is now called `OBS_GetMeta()`
* Additional signature for `OBS_GetData` which can take an array of `TEXT`,
mimicking functionality of `OBS_GetMeasureByID`
__Improvements__
* Generate fixtures from `obs_meta`
* Remove unused table-level code
* Refactor all augmentation and geometry functions to obtain data from
`OBS_GetMeta()` and `OBS_GetData()`.
* Improvements to `OBS_GetMeta()` so it can still fill in metadata in cases
where only a geometry is being requested.
* `OBS_GetData()` returns two-column table instead of anonymous record.
* `OBS_GetData()` can return categorical (text) and geometries
__Bugfixes__
* Remove unnecessary dependency on `postgres_fdw`
* `OBS_GetData()` now aggregates measures with mixed geoms correctly
1.2.1 (2017-01-17)
------------------
__Improvements__
* Support Point/LineString in responses from `OBS_GetBoundary`.
([#243](https://github.com/CartoDB/observatory-extension/pull/233))
1.2.0 (2016-12-28)
------------------
__API Changes__
* Added `OBS_GetMeasureDataMulti`, which takes an array of geomvals and
parameters as JSON, and returns a set of RECORDs keyed by the vals of the
geomvals.
* Added `OBS_GetMeasureMetaMulti`, which takes sparse metadata as JSON (for
example, the measure ID) and returns a filled-out version of the metadata
sufficient for use with `OBS_GetMeasureDataMulti`.
__Improvements__
* Move tests to 2015
* Fixes to `_OBS_GetGeometryScores` to avoid spamming NOTICEs about all pixels
for a band being NULL
* Tests for `_OBS_GetGeometryScores` with complex geometries
* Performance tests for `OBS_GetMeasureDataMulti`
* Return both `table_id` and `column_id` from `_OBS_GetGeometryScores`
1.1.7 (2016-12-15)
------------------
__Improvements__
* Use simpler raster table and simplified `_OBSGetGeometryScores` functions to
improve performance
* In cases where geometry passed into geometry scoring function has greater
than 10K points, simply use its buffer instead
* Add `IMMUTABLE` to `_OBSGetGeometryScores`
* Add tests explicitly for `_OBSGetGeometryScores` in perftest.py
* Yields a ~50% improvement in performance for `_OBSGetGeomeryScores`.
1.1.6 (2016-12-08)
------------------
__Bugfixes__
* Fix divide by zero condition in "denominator" branch of `OBS_GetMeasure`
when passing in a polygon ([#233](https://github.com/CartoDB/observatory-extension/pull/233)).
__Improvements__
* Use `ST_Subdivide` to improve performance when functions are called on very
complex geometries (with many points) ([#232](https://github.com/CartoDB/observatory-extension/pull/232))
* Improve raster scoring to more heavily weight boundaries with nearer to
correct number of points, and penalize boundaries with lots of blank space
([#232](https://github.com/CartoDB/observatory-extension/pull/232))
* Remove some redundant area calculations in `OBS_GetMeasure`
([#232](https://github.com/CartoDB/observatory-extension/pull/232))
* Replace use of `format('%L', var)` with proper use of `EXECUTE` and `$1` etc.
variables ([#231](https://github.com/CartoDB/observatory-extension/pull/231))
* Add test point for Brazil
([#229](https://github.com/CartoDB/observatory-extension/pull/229))
* Improvements to performance tests
([#229](https://github.com/CartoDB/observatory-extension/pull/229))
- Support simple and complex geometries
- Handle all code branches
- Add ability to persist results to JSON for graph visualization later
1.1.5 (2016-11-29)
------------------
__Bugfixes__
* Return `NULL` instead of raising an exception when a measure is requested for
a geometry where it does not exist ([#220](https://github.com/CartoDB/observatory-extension/issues/220)).
1.1.4 (2016-11-21)
------------------
__Bugfixes__
* Fix duplicate subsections with only a partial set of measures appearing from
`OBS_GetLegacyMetadata` ([#216](https://github.com/CartoDB/observatory-extension/issues/216)).
1.1.3 (2016-11-15)
------------------
* Temporarily ignore EU data for the sake of testing
1.1.2 (2016-11-09)
------------------

------------------
__Bugfixes__
* Fixed some minor errors in test suite
__Improvements__
* We now generate test fixtures from local data instead of remote server
([#120](https://github.com/CartoDB/observatory-extension/issues/120))
__API Changes__
* New function, `OBS_LegacyBuilderMetadata`, which resolves
([#133]( https://github.com/CartoDB/observatory-extension/issues/133))
* Creates "dimensional" metadata grabbing functions
(`OBS_GetAvailableNumerators`, `OBS_GetAvailableDenominators`,
`OBS_GetAvailableGeometries`, `OBS_GetAvailableTimespans`) which will be
used for obtaining metadata in the replacement for the Data Library
([CartoDB/design#104](https://github.com/CartoDB/design/issues/104)). This
is also referred to here ([CartoDB/design#68](https://github.com/CartoDB/design/issues/68)).
1.0.7 (2016-09-20)
------------------
__Bugfixes__

in combination with a non-summable measure ([cartodb/issues
#9063](https://github.com/CartoDB/cartodb/issues/9063))
* Unnecessary dependencies on cartodb and plpythonu removed
([#161](https://github.com/CartoDB/observatory-extension/issues/161))

([#162](https://github.com/CartoDB/observatory-extension/issues/162))
* Area normalization done by square kilometer instead of square meter for
polygons ([#158](https://github.com/CartoDB/observatory-extension/issues/158))
* `postgres-fdw` installed as required in unit test environment
([#166](https://github.com/CartoDB/observatory-extension/issues/166))
__Improvements__
* Added tests to make sure all functions can handle explicit NULL as default
([#159](https://github.com/CartoDB/observatory-extension/issues/159))

---
__Bugfixes__
* Fix for `OBS_GetCategory` outside the US ([#135](https://github.com/CartoDB/observatory-extension/pull/137))

a multi/polygon. Previously, no normalization was erroneously assumed.
__Improvements__
* Automated tests cover Mexico data
* `obs_meta` is now provisioned during unit tests
* `obs_meta` is now used during end-to-end tests
* `OBS_GetMeasureByID` uses `obs_meta` internally, which should help
performance

* `OBS_GetCategory` will pick the correct category for an arbitrary polygon
(the category covering the highest % of that polygon)
* `OBS_GetMeasure` has been updated to use `obs_meta` internally, which should
help performance
* `OBS_GetMeasure` now can be passed "none" and skip normalization by area or
denominator for points
