* Add jobs for grouping similar photos in PhotoGroups
Outline:
- The first photo-dhash job adds a dhash field to each photo. The dhash is a 128 bit
downsampled representation of the photo that works well for visual similarity comparisions.
- The second photo-dedup job groups photos that have similar dhash's into PhotoGroups.
fixes: #2787
* Implement noms cli configuration support
- Introduce .nomsconfig
- Supports a default db to use when no explicit db is given
- Supports defining db aliases to use as short hand for db urls
- See samples/cli/nomsconfig for more info
fix: #2131
You can run these yourself using the -perf flag, e.g.
> noms serve &
> go test -v -perf http://localhost:8000 ./samples/go/csv/csv-import
> noms ds http://localhost:8000
Though you'll need to go-get github.com/attic-labs/testdata.
Note that all of this only records test results, it doesn't have any
concept of failing perf (unless test assertsions themselves fail). It
will be the job of some other Noms client (work in progress) to do that.
I will be setting this up to run continuously momentarily.
This adds a simple client which fetches a URL into a noms blob. In a separate change, I will change csv_importer to link up to this rather than reading from a file.
Note: I was sad to see that chunking performance here is quite slow. We can chunk at the rate of about 150kB second on a single core, and it's cpu-bound.
