* | ia: set User-Agent for replay fetch from wayback | Bryan Newbold | 2020-03-29 | 1 | -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 code | Bryan Newbold | 2020-03-27 | 1 | -0/+2 |

* | ia: more conservative use of clean_url() | Bryan Newbold | 2020-03-24 | 1 | -3/+5 |
| | | | | | | Fixes AttributeError: 'NoneType' object has no attribute 'strip' Seen in production on the lookup_resource code path. | ||||
* | ingest: clean_url() in more places | Bryan Newbold | 2020-03-23 | 1 | -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 Newbold | 2020-03-18 | 1 | -0/+1 |

* | implement (unused) force_get flag for SPN2 | Bryan Newbold | 2020-03-18 | 1 | -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 Newbold | 2020-03-17 | 1 | -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. | ||||

* | fetch_petabox_body: allow non-200 status code fetches | Bryan Newbold | 2020-02-24 | 1 | -2/+10 |
| | | | | | | But only if it matches what the revisit record indicated. This is mostly to enable better revisit fetching. | ||||
* | allow fuzzy revisit matches | Bryan Newbold | 2020-02-24 | 1 | -1/+26 |

* | ia: improve warc/revisit implementation | Bryan Newbold | 2020-02-22 | 1 | -26/+46 |
| | | | | | A lot of the terminal-bad-status seems to have due to not handling revisits correctly. They have status_code = '-' or None. | ||||
* | cdx: handle empty/null CDX response | Bryan Newbold | 2020-02-22 | 1 | -0/+2 |
| | | | | Sometimes seem to get empty string instead of empty JSON list | ||||

* | wayback: on bad redirects, log instead of assert | Bryan Newbold | 2020-02-18 | 1 | -2/+13 |
| | | | | This is a different form of mangled redirect. | ||||
* | attempt to work around corrupt ARC files from alexa issue | Bryan Newbold | 2020-02-18 | 1 | -0/+5 |
| | |||||
* | handle alternative dt format in WARC headers | Bryan Newbold | 2020-02-05 | 1 | -2/+4 |
| | | | | | If there is a UTC timestamp, with trailing 'Z' indicating timezone, that is valid but increases string length by one. | ||||

* | hack-y backoff ingest attempt | Bryan Newbold | 2020-02-03 | 1 | -2/+11 |
| | | | | | | | | | | | | | | | The goal here is to have SPNv2 requests backoff when we get back-pressure (usually caused by some sessions taking too long). Lack of proper back-pressure is making it hard to turn up parallelism. This is a hack because we still timeout and drop the slow request. A better way is probably to have a background thread run, while the KafkaPusher thread does polling. Maybe with timeouts to detect slow processing (greater than 30 seconds?) and only pause/resume in that case. This would also make taking batches easier. Unlike the existing code, however, the parallelism needs to happen at the Pusher level to do the polling (Kafka) and "await" (for all worker threads to complete) correctly. | ||||
* | wayback: try to resolve HTTPException due to many HTTP headers | Bryan Newbold | 2020-02-02 | 1 | -1/+9 |
| | | | | | | | | | This is withing GWB wayback code. Trying two things: - bump default max headers from 100 to 1000 in the (global?) http.client module itself. I didn't think through whether we would expect this to actually work - catch the exception, record it, move on | ||||

| | |||||
* | wayback replay: catch UnicodeDecodeError | Bryan Newbold | 2020-01-15 | 1 | -0/+2 |
| | | | | | | | | In prod, ran in to a redirect URL like: b'/web/20200116043630id_/https://mediarep.org/bitstream/handle/doc/1127/Barth\xe9l\xe9my_2015_Life_and_Technology.pdf;jsessionid=A9EFB2798846F5E14A8473BBFD6AB46C?sequence=1' which broke requests. | ||||

| | |||||
* | fix revisit resolution | Bryan Newbold | 2020-01-15 | 1 | -4/+12 |
| | | | | | Returns the *original* CDX record, but keeps the terminal_url and terminal_sha1hex info. | ||||
* | SPNv2 doesn't support FTP; add a live test for non-revist FTP | Bryan Newbold | 2020-01-14 | 1 | -0/+10 |
| | |||||
* | basic FTP ingest support; revist record resolution | Bryan Newbold | 2020-01-14 | 1 | -34/+77 |
| | | | | | | | - supporting revisits means more wayback hits (fewer crawls) => faster - ... but this is only partial support. will also need to work through sandcrawler db schema, etc. current status should be safe to merge/use. - ftp support via treating an ftp hit as a 200 | ||||

| | |||||
* | handle SPNv2-then-CDX lookup failures | Bryan Newbold | 2020-01-10 | 1 | -6/+23 |
| | | | | | | - use a 10 second delay if CDX result isn't immediately available. blech. - if there is a lookup failure, call it a wayback-error and move on | ||||
* | SPNv2 hack specifically for elsevier lookups | Bryan Newbold | 2020-01-10 | 1 | -0/+15 |
| | | | | | I'm not really sure why this is needed, and maybe with more careful testing it isn't. But it works! | ||||
* | add support for redirect lookups from replay | Bryan Newbold | 2020-01-10 | 1 | -9/+69 |
