DATA-1935 Investigate issues with refresh materialized views debouncing incorrectly.

Description

The EWT have been having issues with uploaded data collections taking a long time to reflect the updates in FDW. The is because the refresh materialized views have not been running correctly. These can be run manually by ssh-ing into the server and running the commands from psql, like the below;

psql -c "REFRESH MATERIALIZED VIEW CONCURRENTLY price_marketpricefacts_materialized";

It looks as though at least the price_marketpricefacts_materialized is being continually debounced and not actually running. We see a log message like the below;

Task common.tasks.refresh_materialized_view[5d089b85-9811-48ed-a854-1938387de3b9] succeeded in 0.05116157094016671s: 'Request received for refresh_materialized_view_refresh_materialized_view-materialized_view=price_marketpricefacts_materialized while DEBOUNCING so re-scheduled, id 901fd5c6-04fc-4897-be17-7ad3cac3e369 eta 2022-09-30 11:49:53.046322+00:00.'

and tracing the new task that has been spawned we see the below log;

Task common.tasks.refresh_materialized_view[901fd5c6-04fc-4897-be17-7ad3cac3e369] succeeded in 0.03576034493744373s: 'Task refresh_materialized_view_refresh_materialized_view-materialized_view=price_marketpricefacts_materialized triggered to run twice, so cancelling second call 901fd5c6-04fc-4897-be17-7ad3cac3e369.'

The only reason that the code can be reached to execute the last log statement is if the debounce method fails to delete the HERD:{task_key} from the cache. This could happen if the HERD:{task_key} is not set in the first place. Chris Preager Could this also happen if the tasks are on different servers?

The code has the following comment.

# This can be caused by:
#     1. This cache delete occurs just before cache_set(HERD) in apply_async, deletes nothing, or
#        apply_async enqueues a debounce while this is running, and then this method enqueues a
#        duplicate below due to the renewed ETA.
#     2. This cache_delete(HERD) runs immediately after cache_set(HERD) in apply_async, so a
#        second call to apply_async goes through. In this case the latter call won't run after
#        debounce_wait seconds, but will be satisfied by this run anyway. A subsequent call will run fine.

DATA-1938 Fix Comtrade unit test erros

Update FAO pipeline based on changes in remote API (DATA-1943)

Description

The help ticket reported

1. the datasereis api url is changed from https://fpma.apps.fao.org/giews/food-prices/tool/api/v1/series/ to https://fpma.fao.org/giews/v4/price_module/api/v1/FpmaSerie/

2. The current version also require a two step process to fetch the datapoints.
   First https://fpma.fao.org/giews/v4/price_module/api/v1/FpmaSerie/ returns the list of dataseries. Each dataseries has a guid type identifier as oppose to the previous api's series_id [eg. 8_23_642_2_434_nominal
   Then the datapoints can be fetched from a url like:
   https://fpma.fao.org/giews/v4/price_module/api/v1/FpmaSeriePrice/e23b83a7-7cf7-40b0-87f7-6c03a2d3b2bc/ and there is no datapoint_url now included in each dataseries

3. the seriesId is now has a different datatype - Guid and the column is named uuid

4. fao Country Code of value XXX used to be used to refer international prices, now they replaced that with IPS

5. market is now an id and market_name contains the name, commodity_name contains the product name where commodity used to reference

6. dateRanges field is now periodicity

These changes have side effect on the pipeline and we need to update it accordingly.

DATA-1954 Fix safety warning for protobuf

Description

The below safety error is causing issues in the CI pipelines.

protobuf | 3.20.1 | >=3.20.0rc0,<3.20.2 | 51167 |

A parsing vulnerability for the MessageSet type in the ProtocolBuffers versions prior to and including 3.16.1, 3.17.3, 3.18.2, 3.19.4, 3.20.1 and 3.21.5 for protobuf-cpp, and versions prior to and including 3.16.1, 3.17.3, 3.18.2, 3.19.4, 3.20.1 and 4.21.5 for protobuf-python can lead to out of memory failures. A specially crafted message with multiple key-value per elements creates parsing issues, and can lead to a Denial of Service against services receiving unsanitized input. We recommend upgrading to versions 3.18.3, 3.19.5, 3.20.2, 3.21.6 for protobuf-cpp and 3.18.3, 3.19.5, 3.20.2, 4.21.6 for protobuf-python. Versions for 3.16 and 3.17 are no longer updated.

was selected. This error has been corrected and users can now update data source document names.

Refreshed FDE Fixes

A variety of fixes and updates were completed for the refreshed FDE based on testing and feedback:

• Exchange rate type filter was added (DATA-1958)

• Fixed scroll arrows in data selection table (DATA-1961)

• Changed Markets from M49 to FN Regions (DATA-1983)

• Changed FDE sidebar domain title to "Acute Food Insecurity Classifications" (DATA-2007)

• Limited filter options based on available data (DATA-2012, DATA-2013)

• Fixed a bug with the start date filter in the Price domain (DATA-2070)

Bug when uploading XLSForm, both in old fdw KoBo and latest version

...

(DATA-2010)

When uploading XLSForms sometimes there is no task registered. This has been fixed and XLSForms can now be successfully uploaded to the deployments.

SaveNewArticles fails for articles from multiple sources

...

Description

SaveNewArticle relies on ReadExistingArticles to avoid inserting duplicates.

...

(DATA-2083)

An error was occurring when an article with the same URL has was been downloaded from a different source, then it attempts to save the article using batch_insert, which raises IntegrityError.

This is happening at the moment for the UK FCDO source, which duplicates some (but not all) articles with the UK.gov source.

We will fix this by falling back to saving individual articles if we hit an error, and ignoring the duplicatestwo different sources. This has been fixed and articles are now being ingested without error.
