Introduce photo-dedup-by-date
This program deduplicates photos by the date they were taken. It considers two photos a group if they were separated by less than 5 seconds.
This is a side-by-side port, taking inspiration from the old dataspec.go
code. Notably:
- LDB support has been added in Go. It wasn't needed in JS.
- There is an Href() method on Spec now.
- Go now handles IPV6.
- Go no longer treats access_token specially.
- Go now has Pin.
- I found some issues in the JS while doing this, I'll fix later.
I've also updated the config code to use the new API so that basically
all the Go samples use the code, even if they don't really change.
* 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
The big change here is adding a new Spec class in spec.js. This replaces
DatabaseSpec/DatasetSpec/PathSpec in specs.js, but I'm leaving those in
and moving code over in a later patch. For now, only photos UI.
The photos UI change is to plumb through the authorization token through
the Spec code. For now, it's reading it from a URL parameter, but soon
I'll make it session based (probably localStorage).
The demo-server change is to add the Authorization header into CORS.
Private databases begin with "/p/" - for example, "/kalman" is not
private, but "/p/kalman" is private. They are not the same database.
The bulk of this work is the receipt infrastructure.
A receipt is form data that gives access to a database, encrypted using
secretbox. For example, "Database=/p/kalman&Date=12345678" might encrypt
to "SFH5bcIJ3_XgEbtmi_AdCKTItW20fl90czVl5_pF5PAXhNQ366U1yOpYGAjT".
* A new tool receiptkey generates random receipt (secretbox) keys.
* A new tool receipttool generates receipts for databases.
* demo-server has been updated to check for a receipt in the
Authorization header to access private databases.
receipttool and demo-server must be given the same receipt key.
Add optional merging functionality to noms commit.
noms merge <database> <left-dataset-name> <right-dataset-name> <output-dataset-name>
The command above will look in the given Database for the two named
Datasets and, if possible, merge their HeadValue()s and commit the
result back to <output-dataset-name>.
Fixes#2535
Performs face merge functionality, it takes a photo's set of
face center points and face rectangles and returns the
set of faces in which the face rectangle contains the face
center point. We store a new photo object with a set of faces, that
have the names from the face center points and the rectangles from the
face rectangles.
* dropbox/find-photos: encode auth token in photo URLs so they can
work in UI.
* Remove requirement for datePublished from photo-index
Dropbox doesn't have a publish date
* fix test
* review comments
* npm test
This puts the flow header after the copyright header.
It also:
* fixes the existing files to have valid headers
* Makes sure the script can handle doctype
* Introduce samples/js/dropbox/slurp
Doing the filter step will be a bit different because Dropbox does
not provide secret URLs for every photo by default. Requests have
to be oauth-authenticated so we'll have to figure out how to do
that.
* vendor golang.org/x/oauth2 and golang.org/x/net
* Introduce oauthify and modify dropbox/slurp to use
demo-server was using a read-through cache to allow it to serve more
concurrent requests more quickly by reducing disk I/O. As seen in issue
across Databases, leading to incorrect sync results in some instances.
Since we're not worried about demo-server load right now, simply delete
the cache.
Fixes#2688
