Add option `--cdxserver-dedup-lru-cache-size=N` (default None) to enable
in-memory caching of CDX dedup requests using stdlib `lru_cache` method.
Cache memory info is available on `INFO` logging outputs like:
```
CacheInfo(hits=3172, misses=3293, maxsize=1024, currsize=1024)
``
`CdxServerDedupLoader` used `max_workers=400` by default.
We make it a CLI option `--cdxserver-dedup-max-threads` with a default
value of 400.
We need to be able to tweak this setting because it creates too many CDX
queries which cause problems with our production CDX servers.
Method `warcprox.dedup.decorate_with_dedup_info` is only used in
`DedupLoader._process_url` and nowhere else.
The problem is that `decorate_with_dedup_info` cannot get warcprox cli
options. Thus we cannot pass the custom min size limits.
New `--dedup-min-text-size` and `--dedup-min-binary-size` cli options
with default value = `0`.
New `DedupableMixin` which can be used in any dedup class. It is
currently used only in CDX dedup. Instead of checking `payload_size() >
0`, we now use `.is_dedupable(recorded_url)`
New utility method `RecordedUrl.is_text`.
Check for not empty captured content (`payload_size() > 0`) before
creating a new thread and running a CDX dedup request.
Most dedup modules perform the same check to avoid unnecessary dedup
requests.
Increase CDX dedup max workers from 200 to 400 in order to handle more
load.
Set `user-agent: warcprox` for HTTP requests we send to CDX server. Its
useful to identify and monitor `warcprox` requests.
Pass HTTP headers to connection pool on init and not on each request.
Each dedup bucket (in archive-it, generally one per seed) requires a
separate http request. The batches of urls processed by the trough dedup
loader and storer may include multiple dedup buckets. This commit makes
those all the trough queries in a given batch run in parallel, using a
thread pool.
It is necessary to pass cookies to the CDX Server we use for deduplication.
To do this, we add the optional CLI argument
``--cdxserver-dedup-cookies="cookie1=val1;cookie2=val2"`` and if it is
available, its used in the `Cookie` HTTP header in CDX server requests.
* master:
fix running_stats thing
Update CdxServerDedup unit test
Chec writer._fname in unit test
Configurable CdxServerDedup urllib3 connection pool size
Yet another unit test fix
Change the writer unit test
fix github problem with unit test
Another fix for the unit test
Fix writer unit test
Add WarcWriter warc_filename unit test
Fix warc_filename default value
Configurable WARC filenames
urllib3 pool has default ``maxsize=1``
http://urllib3.readthedocs.io/en/latest/advanced-usage.html.
We need to set a higher value because we get warnings like this:
```
2018-01-15 20:04:10,044 18436 WARNING WarcWriterThread030(tid=18502)
urllib3.connectionpool._put_conn(connectionpool.py:277) Connection pool
is full, discarding connection: wwwb-dedup
```
We set value: ```cdxserver_maxsize = args.writer_threads or 200```.
Note that the ideal would be to use this
https://github.com/internetarchive/warcprox/blob/master/warcprox/main.py#L284
but it is initialized after dedup, there is a dependency and we cannot
use it.
* master:
hopefully fix test failing occasionally apparently due to race condition by checking that the file we're waiting for has some content
fix payload digest by pulling calculation up one level where content has already been transfer-decoded
new failing test for correct calculation of payload digest
missed a spot handling case of no warc records written
* master:
not gonna bother figuring out why pypy regex is not matching https://travis-ci.org/internetarchive/warcprox/jobs/299864258#L615
fix failing test just committed, which involves running "listeners" for all urls, including those not archived; make adjustments accordingly
make test_crawl_log expect HEAD request to be logged
fix crawl log handling of WARCPROX_WRITE_RECORD request
modify test_crawl_log to expect crawl log to honor --base32 setting and add tests of WARCPROX_WRITE_RECORD request and HEAD request (not written to warc)
bump dev version number
add --crawl-log-dir option to fix failing test
create crawl log dir at startup if it doesn't exist
make test pass with py27
fix crawl log test to avoid any dedup collisions
fix crawl log test
heritrix-style crawl log support
