| | | | Broke this in earlier refactor.
* ia: use newer gwb (petabox) loading classBryan Newbold2020-11-041-5/+8
| | | | This fixes zstandard WARC reading.

|
* ingest: tweak debug printing alignmentBryan Newbold2020-11-031-8/+7
|
* cdx: fix 'closest' supportBryan Newbold2020-11-031-3/+2
|
* cdx: add support for 'closest' time parameterBryan Newbold2020-10-301-3/+9
|
* ingest: decrease CDX timeout retries againBryan Newbold2020-10-221-1/+1
|
* differential wayback-error from wayback-content-errorBryan Newbold2020-10-211-10/+13
| | | | | | The motivation here is to distinguish errors due to current content in wayback (eg, in WARCs) from operational errors (eg, wayback machine is down, or network failures/disruption).
* SPN CDX delay now seems reasonable; increase to 40sec to catch mostBryan Newbold2020-10-191-1/+1
|
* CDX: when retrying, do so every 3 seconds up to limitBryan Newbold2020-10-191-5/+9
|
* SPN: more verbose status loggingBryan Newbold2020-10-191-0/+4
|
* CDX: revert post-SPN CDX lookup retry to 10 secondsBryan Newbold2020-10-191-1/+1
| | | | | Hoping to have many fewer SPN requests and issues, so willing to wait longer for each.
* ingest: catch wayback-fail-after-SPN as separate statusBryan Newbold2020-10-191-4/+17
|
* SPN: better log line when starting a requestBryan Newbold2020-10-191-0/+1
|
* SPN: look for non-200 CDX responsesBryan Newbold2020-10-191-1/+1
| | | | Suspect that this has been the source of many `spn2-cdx-lookup-failure`
* SPN: better check for partial URLs returnedBryan Newbold2020-10-191-2/+2
|
* CDX fetch: more permissive fuzzy/normalization checkBryan Newbold2020-10-191-3/+9
| | | | | | | This might the source of some `spn2-cdx-lookup-failure`. Wayback/CDX does this check via full-on SURT, with many more changes, and potentially we should be doing that here as well.
* ingest: experimentally reduce CDX API retry delayBryan Newbold2020-10-171-1/+1
| | | | | | | This code path is only working about 1/7 times in production. Going to try with a much shorter retry delay and see if we get no success with that. Considering also just disabling this attempt all together and relying on retries after hours/days.
* ingest: handle cookieAbsent and partial SPNv2 URL reponse cases betterBryan Newbold2020-10-171-0/+31
|
* store no-capture URLs in terminal_urlBryan Newbold2020-10-121-1/+1
|
* Revert "ingest: reduce CDX retry_sleep to 3.0 sec (after SPN)"Bryan Newbold2020-08-111-1/+1
| | | | | | | This reverts commit 92bf9bc28ac0eacab2e06fa3b25b52f0882804c2. In practice, in prod, this resulted in much larger spn2-cdx-lookup-failure error rates.
* ingest: reduce CDX retry_sleep to 3.0 sec (after SPN)Bryan Newbold2020-08-111-1/+1
| | | | | | | | As we are moving towards just retrying entire ingest requests, we should probably just make this zero. But until then we should give SPN CDX a small chance to sync before giving up. This change expected to improve overall throughput.
* refactor: force_get -> force_simple_getBryan Newbold2020-08-111-5/+5
| | | | | For clarity. The SPNv2 API hasn't changed, just changing the variable/parameter name.
* spn2: skip js behavior (experiment)Bryan Newbold2020-08-051-0/+1
| | | | | Hoping this will increase crawling throughput with little-to-no impact on fidelity.
* SPN2: ensure not fetching outlinksBryan Newbold2020-08-051-0/+1
|
* use new SPNv2 'skip_first_archive' paramBryan Newbold2020-07-221-0/+1
| | | | For speed and efficiency.
* report revisit non-200 as a WaybackErrorBryan Newbold2020-06-261-7/+7
|
* pdf: mypy and typo fixesBryan Newbold2020-06-171-1/+1
|
* ingest: quick hack to capture CNKI outlinksBryan Newbold2020-04-131-2/+9
|
* ia: set User-Agent for replay fetch from waybackBryan Newbold2020-03-291-0/+5
| | | | | | | Did this for all the other "client" helpers, but forgot to for wayback replay. Was starting to get "445" errors from wayback.
* ingest: better spn2 pending error codeBryan Newbold2020-03-271-0/+2
|
* ia: more conservative use of clean_url()Bryan Newbold2020-03-241-3/+5
| | | | | | Fixes AttributeError: 'NoneType' object has no attribute 'strip' Seen in production on the lookup_resource code path.
* ingest: clean_url() in more placesBryan Newbold2020-03-231-1/+4
| | | | | | Some 'cdx-error' results were due to URLs with ':' after the hostname or trailing newline ("\n") characters in the URL. This attempts to work around this categroy of error.
* ingest: log every URL (from ia code side)Bryan Newbold2020-03-181-0/+1
|
* implement (unused) force_get flag for SPN2Bryan Newbold2020-03-181-3/+4
| | | | | | | | | I hoped this feature would make it possible to crawl journals.lww.com PDFs, because the token URLs work with `wget`, but it still doesn't seem to work. Maybe because of user agent? Anyways, this feature might be useful for crawling efficiency, so adding to master.
* work around local redirect (resource.location)Bryan Newbold2020-03-171-1/+6
| | | | | | Some redirects are host-local. This patch crudely detects this (full-path redirects starting with "/" only), and appends the URL to the host of the original URL.
* ia: catch wayback ChunkedEncodingErrorBryan Newbold2020-03-051-0/+3
|
* fix warc_offset -> offsetBryan Newbold2020-02-241-1/+1
|
* ingest: handle broken revisit recordsBryan Newbold2020-02-241-1/+4
|
* ingest: treat CDX lookup error as a wayback-errorBryan Newbold2020-02-241-1/+4
|
* fetch_petabox_body: allow non-200 status code fetchesBryan Newbold2020-02-241-2/+10
| | | | | | But only if it matches what the revisit record indicated. This is mostly to enable better revisit fetching.
* allow fuzzy revisit matchesBryan Newbold2020-02-241-1/+26
