You can test OnCalendar strings using systemd-analyze calendar, eg: # systemd-analyze calendar '*-*-* 06:00:00,18:00:00' Failed to parse calendar specification '*-*-* 06:00:00,18:00:00': Invalid argument # systemd-analyze calendar '*-*-* 06,18:00:00' Normalized form: *-*-* 06,18:00:00 Next elapse: Wed 2018-09-26 06:00:00 EEST (in UTC): Wed 2018-09-26 03:00:00 UTC From now: 6h left	2018-09-25 23:07:03 +03:00

Alan Orth	280d211d56	CHANGELOG.md: Add note about kazoo 2.5.0	2018-09-25 12:12:10 +03:00
Alan Orth	806d63137f	requirements.txt: Use kazoo 2.5.0 ... SolrClient 0.2.1 currently depends on kazoo 2.2.1, but there is an issue with Python 3.7 in kazoo <= 2.5.0. Kazoo 2.5.0 fixes the is- sue with Python 3.7, and for my limited usage of SolrClient it se- ems to work fine.

Alan Orth	4cf8656b35	Change / route to /items ... I think it's more obvious if the "all items" route is plural. Also, this will allow me to eventually put documentation at the root.	2018-09-25 11:34:07 +03:00

Alan Orth	46a1476ab0	Add requirements.txt ... Generated with `pip freeze`. This is so I can pin the versions of packages that I've tested with as well as to allow Travis to test whether the project runs on various Pythons and to let GitHub in- form me of vulnerabilities in some libraries.	2018-09-25 11:02:50 +03:00
Alan Orth	87dbb6c4df	CHANGELOG.md: Release version 0.2.1	2018-09-25 02:21:44 +03:00
Alan Orth	3160c44566	app.py: Remove comment ... This comment was added when I first began the application and the testing status is documented in the README now.	2018-09-25 02:20:51 +03:00
Alan Orth	4b72f626d9	Update string substitution format ... Instead of doing numbered strings I will just depend on the order, at least to be consistent.	2018-09-25 02:19:29 +03:00
Alan Orth	2d3b7620e3	CHANGELOG.md: Add note about psycopg2.extras.DictCursor	2018-09-25 02:08:54 +03:00
Alan Orth	6e4bc630f7	database.py: Use psycopg2.extras.DictCursor ... This allows us to access records using their column name. I didn't notice that this was not working, as I had been testing the wrong server! See: http://initd.org/psycopg/docs/extras.html	2018-09-25 02:06:29 +03:00

Alan Orth	74ff86ee3b	contrib: Update environment settings in system units	2018-09-25 01:10:14 +03:00
Alan Orth	3327884f21	Update docs to remove SQLite stuff ... I've decided to use PostgreSQL instead of SQLite because the UPSERT support is available in versions of PostgreSQL we're alread running, whereas SQLite needs a VERY new (3.24.0) version that is not avail- able on any recent long-term support Ubuntu releases.	2018-09-25 00:56:01 +03:00
Alan Orth	8f7450f67a	Use PostgreSQL instead of SQLite ... I was very surprised how easy and fast and robust SQLite was, but in the end I realized that its UPSERT support only came in version 3.24 and both Ubuntu 16.04 and 18.04 have older versions than that! I did manage to install libsqlite3-0 from Ubuntu 18.04 cosmic on my xenial host, but that feels dirty. PostgreSQL has support for UPSERT since 9.5, not to mention the same nice LIMIT and OFFSET clauses.	2018-09-25 00:49:47 +03:00

Alan Orth	42e8f17305	CHANGELOG.md: Add note about route for all items	2018-09-24 16:13:05 +03:00
Alan Orth	19a45f3f6f	app.py: Add route to page through all item statistics ... This route exposes all item statistics and uses the limit and offset parameters to control paging throug the result set. The logic here is extremely easy thanks to the brilliant LIMIT and OFFSET features of SQLite (of course the SQL query sorts the results by some unique field to ensure the order is already the same).	2018-09-24 16:07:26 +03:00
Alan Orth	505ef31101	CHANGELOG.md: Add note about UPSERT	2018-09-24 14:31:05 +03:00
Alan Orth	1543cacc54	app.py: Update SQL logic to use single table ... The indexer.py script was updated to use a single table because I learned about UPSERT. This simplifies the database schema and the Python logic, and makes it easier to page all views and downloads at once without complicated JOIN queries.	2018-09-24 14:28:00 +03:00
Alan Orth	2cab456f16	indexer.py: Use single items table with UPSERT ... I was using two separate tables for item views and downloads without realizing that SQLite didn't support FULL OUTER JOIN, which would be needed to get views and downloads for a given item in a single query. Instead I can use one table with a default value of 0 for both views and downloads, and then use "UPSERT" to populate the statistics. This is a newish SQL concept that allows you to attempt an INSERT and then specify an action to perform in case of conflict. This works well in SQLite and actually simplifies my Python logic greatly! Note that the "excluded" table qualifier is a special keyword that allows you to reference the value that would have been inserted.

Alan Orth	a51422273c	Remove SOLR_CORE configuration variable ... This parameter is not customizable. All DSpace instances use this name for the Solr statistics core.	2018-09-24 00:20:54 +03:00
Alan Orth	89621af85d	Split database access into RW and RO ... The indexer need to be able to write to the database, but the API only needs to read it.	2018-09-24 00:00:05 +03:00
Alan Orth	c554404d7f	CHANGELOG.md: Add systemd units for indexer	2018-09-23 23:15:27 +03:00
Alan Orth	90d7a452bd	contrib: Add systemd units for indexer ... An example systemd service unit for the indexer and an accompanying timer unit.	2018-09-23 23:13:43 +03:00

Alan Orth	e1b9d1284f	Rename project to DSpace Statistics API ... At first I called it "CGSpace" because I was making it specifically for our CGSpace DSpace repository, but the potential here is bigger than that!	2018-09-23 23:02:21 +03:00
Alan Orth	bac764a0a4	CHANGELOG.md: Move entries to version 0.0.4	2018-09-23 16:49:25 +03:00
