This update eliminates all occurrences of the OpenNLP token model from the setup script, configuration, and test files, as this model file is no longer used.
Introduced optional alias domain functionality in EdgeDomain class to handle domain variations such as "www" in the anchor tags code, as there are commonly a number of relevant but glancing misses in the atags data.
Adding a tracking message to the export actor means it's possible to run them in a precession.
Adding a new precession actor, and some GUI components for triggering exports.
The change also adds a heartbeat to the export process.
Add a check to ensure only documents with "text/html" content type are processed in FeedExporter, AtagExporter, and TermFrequencyExporter. This prevents non-HTML documents from being parsed and helps maintain data consistency and keep the memory usage down.
Normalize URLs by replacing en-dash with hyphen to prevent encoding errors. This ensures correct handling of a small subset of articles with improperly normalized UTF-8 paths. Added `normalizeUtf8` method to address this issue.
Fixes issue #109.
To avoid hammering the same invalid URLs for up to two months, URLs that fail to fetch correctly are on a dice roll added to a bad URLs table, that prevents further attempts at fetching them.
Since some of the export tasks have been memory hungry, sometimes killing the executor-services, they've been moved to a separate process that can be given a larger Xmx.
While doing this, the ProcessMainClass was given utilities for the boilerplate surrounding receiving mq requests and responding to them, some effort was also put toward making the process boot process a bit more uniform. It's still a bit heterogeneous between different processes, but a bit less so for now.
This is done by applying a large constant offset to the ordinals for the live crawled documents. The chosen value still permits upto 100k documents to be fetched for a single domain with the live crawler, which is ridiculously large.
Some refactoring is still needed, but an dummy actor is in place and a process that crawls URLs from the livecapture service's RSS endpoints; that makes it all the way to being indexable.

Adding a new @Tag("flaky") for tests that do not reliably return successes. These may still be valuable during development, but should not run in CI.
Also tagging a few of the slower tests with the old @Tag("slow"), to speed up the run-time.
Also be a bit smarter about pre-allocating queues and sets based on depth rather than the number of provided URLs, which was always zero outside of tests.
The crawl spec abstraction was used to upload lists of domains into the system for future crawling. This was fairly clunky, and it was difficult to understand what was going to be crawled.
Since a while back, a new domains listing view has been added to the control view that allows direct access to the domains table. This is much preferred and means the operator can directly manage domains without specs.
This commit removes the crawl spec abstraction from the code, and changes the GUI to direct to the domains list instead.
* Restructure the code to make a bit more sense
* Store full headers in crawl data
* Fix bug in retry-after header that assumed the timeout was in milliseconds, and then clamped it to a lower bound of 500ms, meaning this was almost always handled wrong
To help offer verbatim matches for external link texts, we assign these positions in the document a bit after the actual document ends. Integrating this information with the ranking is not performed here.
This lets the slop library be stand-alone without dependence on coded-sequence.
The change also gets rid of the vestigial seek() method in ColumnReader.
The most common error when dealing with Slop columns is that they can fall out of sync with each other if the programmer accidentally does a conditional read and forgets to skip.
The second most common error is forgetting to close one of the columns in a reader or writer.
To deal with both cases, a new class SlopTable is added that keeps track of the lifecycle of all slop columns and performs a check when closing them that they are in sync.
Turns out throttling to only 1 lock per domain means the crawler chokes hard on large hosting websites such as wordpress. Giving these a slightly larger allowance.
Refactoring keyword extraction to extract spans information.
Modifying the intermediate storage of converted data to use the new slop library, which is allows for easier storage of ad-hoc binary data like spans and positions.
This is a bit of a katamari damacy commit that ended up dragging along a bunch of other fairly tangentially related changes that are hard to break out into separate commits after the fact. Will push as-is to get back to being able to do more isolated work.
Decorates DocumentSentences with information about which HTML tags they are nested in, and removes some redundant data on this rather memory hungry object. Separator information is encoded as a bit set instead of an array of integers.
The change also cleans up the SentenceExtractor class a fair bit. It no longer extracts ngrams, and a significant amount of redundant operations were removed as well. This is still a pretty unpleasant class to work in, but this is the first step in making it a little bit better.
