- The date in MIT license files have been updated to 2022
- Each of the benchmark and example crates are theoretically
a separate package in Cargo's sense. So license files are
added for them as well.

html5gum is a HTML parser that offers lower-level control over which tokens actually get created and are tracked. As such, the extractor doesn't allocate anything tokens it doesn't care about. On some benchmarks it provides a substantial performance boost. The old parser, html5ever is still available by setting the `LYCHEE_USE_HTML5EVER=1` env var.
A while ago, caching was removed due to some issues (see #349).
This is a new implementation with the following improvements:
* Architecture: The new implementation is decoupled from the collector, which was a major issue in the last version. Now the collector has a single responsibility: collecting links. This also avoids race-conditions when running multiple collect_links instances, which probably was an issue before.
* Performance: Uses DashMap under the hood, which was noticeably faster than Mutex<HashMap> in my tests.
* Simplicity: The cache format is a CSV file with two columns: URI and status. I decided to create a new struct called CacheStatus for serialization, because trying to serialize the error kinds in Status turned out to be a bit of a nightmare and at this point I don't think it's worth the pain (and probably isn't idiomatic either).
This is an optional feature. Caching only gets used if the `--cache` flag is set.
This avoids creating a DOM tree for link extraction and instead uses a `TokenSink` for on-the-fly extraction. In hyperfine benchmarks it was about 10-25% faster than the master.
Old: 4.557 s ± 0.404 s
New: 3.832 s ± 0.131 s
The performance fluctuates a little less as well.
Some missing element/attribute pairs were also added, which contain links according to the HTML spec. These occur very rarely, but it's good to parse them for completeness' sake.
Furthermore tried to clean up a lot of papercuts around our types. We now differentiate between a `RawUri` (stringy-types) and a Uri, which is a properly parsed `URI` type.
The extractor now only deals with extracting `RawUri`s while the collector creates the request objects.
* Move to from vec to streams
Previously we collected all inputs in one vector
before checking the links, which is not ideal.
Especially when reading many inputs (e.g. by using a glob pattern),
this could cause issues like running out of file handles.
By moving to streams we avoid that scenario. This is also the first
step towards improving performance for many inputs.
To stay as close to the pre-stream behaviour, we want to stop processing
as soon as an Err value appears in the stream. This is easiest when the
stream is consumed in the main thread.
Previously, the stream was consumed in a tokio task and the main thread
waited for responses.
Now, a tokio task waits for responses (and displays them/registers
response stats) and the main thread sends links to the ClientPool.
To ensure that the main thread waits for all responses to have arrived
before finishing the ProgressBar and printing the stats, it waits for
the show_results_task to finish.
* Return collected links as Stream
* Initialize ProgressBar without length because we can't know the amount of links without blocking
* Handle stream results in main thread, not in task
* Add basic directory support using jwalk
* Add test for HTTP protocol file type (http://)
* Remove deadpool (once again): Replaced with `futures::StreamExt::for_each_concurrent`.
* Refactor main; fix tests
* Move commands into separate submodule
* Simplify input handling
* Simplify collector
* Remove unnecessary unwrap
* Simplify main
* cleanup check
* clean up dump command
* Handle requests in parallel
* Fix formatting and lints

* Reqwest comes with its own request pool, so there's no need in adding
another layer of indirection. This also gets rid of a lot of allocs.
* Remove cache from collector
* Improve error handling and documentation
* Add back test for request caching in single file
