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.
There were several tests in the Database suites that were failing to
close test Databases that had orderedChunkCaches in them (backed by
levelDBs). Close them.
I was ALSO failing to destroy the cache used in LocalDatabase
instances only while testing Pull(). That's cleared up now as well.
ValueStore caches Values that are read out of it, but it doesn't
do the same for Values that are written. This is because we expect
that reading Values shortly after writing them is an uncommon usage
pattern, and because the Chunks that make up novel Values are
generally efficiently retrievable from the BatchStore that backs
a ValueStore. The problem discovered in issue #2802 is that ValueStore
caches non-existence as well as existence of read Values. So, reading
a Value that doesn't exist in the DB would result in the ValueStore
permanently returning nil for that Value -- even if you then go and
write it to the DB.
This patch drops the cache entry for a Value whenever it's written.
Fixes#2802
The httpBatchStore test TestVersionMismatch() expects a panic,
but the test was actually potentially causing MULTIPLE panics.
One due to the version mismatch, and another due to using an
invalid root.
* 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.
It wasn't working on the code coverage tests. Now I restored this
to what it was before these changes (minus removing some features
that chrome and node now supports out of the box)
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
This patch adds an optional MergePolicy field to CommitOptions. It's a
callback. If the caller sets it, then the commit code will look for a
common ancestor between the Dataset HEAD and the provided Commit. If
the caller-provided Commit descends from HEAD, then Commit proceeds as
normal.
If it does not, but there is a common ancestor, the code runs
merge.ThreeWay() on the values of the provided Commit, HEAD, and the
common ancestor, invoking the MergePolicy callback to resolve
conflicts. If merge succeeds, a merge Commit is created that descends
from both HEAD and the caller-provided Commit. This becomes the new
HEAD of the Dataset.
Fixes#2534
Rename the package to eslint-config-noms as documented on the eslint
site.
This allows other npm modules to use and `extends: 'noms'` in their
eslint rc file.
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.
