* pubmed: workaround a networking issueMartin Czygan2021-09-091-24/+21
| | | | | | use an http proxy (https://github.com/miku/ftpup) to fetch files from FTP, keep some retry logic; also, hardcoding the proxy path as this should be a temporary workaround
* pubmed: add option to ftp download with lftpMartin Czygan2021-09-081-2/+31
| | | | | lftp is a classic command line ftp client, and we hope that its retry capabilities are enough of a workaround for the current networking issue
* pubmed harvester: add basic retry logicMartin Czygan2021-08-201-8/+21
| | | | | | | | Related to a previous issue with seemingly random EOFError from FTP connections, this patch wrap "ftpretr" helper function with a basic retry. Refs: fatcat-workers/issues/92151, fatcat-workers/issues/91102
* pubmed: update docsMartin Czygan2021-07-171-2/+3

* pubmed: do not fail when accessing missing fileMartin Czygan2021-07-171-2/+8
| | | | | | | after a sync gap (e.g. 06/07 2021) harvester wanted to fetch a file, that was not on the server (any more) - do not fail in this case we'll need to backfill missing records via full data dump
* pubmed: reconnect on errorMartin Czygan2021-07-161-4/+30
| | | | | | | | | ftp retrieval would run but fail with EOFError on /pubmed/updatefiles/pubmed21n1328_stats.html - not able to find the root cause; using a fresh client, the exact same file would work just fine. So when we retry, we reconnect on failure. Refs: sentry #91102.

* harvest: datacite API yields HTTP 200 with broken JSONMartin Czygan2020-08-101-1/+8
| | | | As a first step: log response body for debugging.

* harvest: fail on HTTP 400Martin Czygan2020-05-291-4/+0
| | | | | | | | | In the past harvest of datacite resulted in occasional HTTP 400. Meanwhile, various API bugs have been fixed (most recently: https://github.com/datacite/lupo/pull/537, https://github.com/datacite/datacite/issues/1038). Downside of ignoring this error was that state lives in kafka, which has limited support for deletion of arbitrary messages from a topic.
* rename HarvestState.next() to HarvestState.next_span()Bryan Newbold2020-05-264-5/+5
| | | | | | | | | "span" short for "timespan" to harvest; there may be a better name to use. Motivation for this is to work around a pylint erorr that .next() was not callable. This might be a bug with pylint, but .next() is also a very generic name.
* HACK: skip pylint errors on lines that seem to be fineBryan Newbold2020-05-223-3/+3
| | | | | It seems to be an inadvertantly ugraded version of pylint saying that these lines are not-callable.
* crossref: switch from index-date to update-dateBryan Newbold2020-03-301-1/+1
| | | | | | This goes against what the API docs recommend, but we are currently far behind on updates and need to catch up. Other than what the docs say, this seems to be consistent with the behavior we want.
* crossref: longer comment about crossref API date fieldsBryan Newbold2020-03-301-2/+22

* Datacite API v2 throws 400, we cannot recover from, currently.Martin Czygan2019-12-271-0/+4
| | | | | | | | | | As a first iteration, just mark the daily batch complete and continue. The occasional HTTP 400 issue has been reported as https://github.com/datacite/datacite/issues/897. A possible improvement would be to shrink the window, so losses will be smaller.
* datacite: update documentation, add links to issuesMartin Czygan2019-12-271-10/+5
|
* datacite: use v2 of the API (flaky)Martin Czygan2019-12-271-5/+28
| | | | | | | | | Update parameter update for datacite API v2. Works fine, but there are occasional HTTP 400 responses when using the cursor API (daily updates can exceed the 10000 record limit for search queries). The HTTP 400 issue is not solved yet, but reported to datacite as https://github.com/datacite/datacite/issues/897.
* refactor kafka producer in crossref harvesterBryan Newbold2019-12-061-21/+26
| | | | | | | | producer creation/configuration should be happening in __init__() time, not 'daily' call. This specific refactor motivated by mocking out the producer in unit tests.
* crossref is_update isn't what I thoughtBryan Newbold2019-12-031-6/+2
| | | | | | | | I thought this would filter for metadata updates to an existing DOI, but actually "updates" are a type of DOI (eg, a retraction). TODO: handle 'updates' field. Should both do a lookup and set work_ident appropriately, and store in crossref-specific metadata.

* HACK: force pylint to ignore urllib3 Retry importBryan Newbold2019-03-151-1/+3
| | | | | | As the code comment mentions, not sure why pylint throws this error. requests and urllib3 are recent, and this code runs fine in tests and QA, and pylint is running (in CI) within pipenv.
