Feature #17119
closedVirtual folder in FUSE/S3/WebDAV with contents defined by a query
Added by Peter Amstutz almost 4 years ago. Updated over 3 years ago.
Description
Suggestion from customer:
Could we define virtual folders in the S3 / WebDAV / FUSE interface whose contents are defined by a query, e.g. filter on collections that have a certain property?
- Define new group_class called "filter"
- Has arvados filters in a property
- Can use with "group contents" API which reads the filters from the "filter" group properties and applies them to the contents query
- "filter" groups cannot own things and cannot have outgoing permission links
- Add support for showing "filter" groups the same way projects/subprojects are displayed in workbench 2
- Add support for navigating to "filter" groups in Go filesystem (used by keep-web) which uses "group contents" API
- When setting filters there should be some validation to prevent user from setting an obviously invalid filter
Implementation:
In controller, get the group object, check the group_class, if it is "filter" then add the filters to the query, and pass along the query to the backend.

FYI I just checked, both arvados.customFileSystem (used by WebDAV/S3) and arvados_fuse.fusedir.ProjectDirectory (FUSE) do separate queries of groups and collections instead of using the "group.contents" endpoint. So they will need to be updated in order for the virtual project behavior to work.
Workbench 2 uses the contents endpoint for project contents and so is likely to work with minimal or no updates.

I'm splitting this work in multiple chunks:
- add the groups endpoints to Controller => 17119-virtual-folder-from-query
- convert arvados.customFileSystem (used by WebDAV/S3) to use the group contents endpoint => 17119-use-group-contents
- convert arvados_fuse.fusedir.ProjectDirectory (FUSE) to use the group contents endpoint => 17119-use-group-contents
- add the code to handle filter groups to Controller
I have a branch ready for review for the first bullet: 1b79e315b0adf2744e1df1781c198cf698b1c181 on branch 17119-virtual-folder-from-query adds the groups endpoints to Controller. Tests have passed at developer-run-tests: #2330

I think it would be better to add an Included field to the GroupList struct, rather than using a separate SharedGroupList struct. Even though the "shared" endpoint is currently the only one that returns anything there, that won't necessarily be true forever. This would mean "list groups" responses would have "included":null but (other than perhaps some sanity-checking tests which could be updated) I don't think this would bother any clients? The other difference I see is that SharedGroupList doesn't have ItemsAvailable -- is that accidental?
Similarly I think we could add an Include field to arvados.ListOptions, and use that instead of introducing a separate SharedOptions struct. We don't implement it for other APIs yet but it does belong there in principle. (Am I right in thinking the UUID field in SharedOptions isn't really used, i.e., this is the only reason for a separate SharedOptions struct?)
Having a separate ContentsOptions seems a little more appropriate since UUID, Recursive, and ExcludeHomeProject don't make a lot of sense in the generic ListOptions struct. I wonder if it should be called GroupContentsOptions though?
Perhaps EndpointGroupContents2 (groups/{uuid}/contents) should be a little more descriptive like EndpointGroupContentsUUIDInPath. Could have a comment like "alternate HTTP route; client-side code should always use EndpointGroupContents instead"
Can we drop the "Kind" fields? So far, we have it in ContainerRequest but all the other structs live without. It seems like we could avoid adding new ones (and delete it from ContainerRequest?) and instead let lib/controller/router add it to http responses on the fly. (Of course in Go code this field is redundant/useless since each struct has a real type.)
(PipelineInstance)Properties, (PipelineInstance)ComponentsSummary, (PipelineInstance)Components, (PipelineTemplate)Components, (Job)Components, (Job)RuntimeConstraints, (Job)TasksSummary, (Trait)Properties should probably be either map[string]interface{} or (if we don't know whether it will be an object or an array) json.RawMessage.

Sounds good, that is a nice simplification. ItemsAvailable should have been on SharedGroupList, that was an omission (the API server exposes it).

Done.
(Am I right in thinking the UUID field in SharedOptions isn't really used, i.e., this is the only reason for a separate SharedOptions struct?)
Yeah, that was a copy/paste from ContentOptions I think, though it was used in `lib/controller/federation/conn.go` which seems dubious - our clients don't send that field afaict. I solved that differently but I am not sure that it's the right approach. I put a 'FIXME' comment in.
Having a separate ContentsOptions seems a little more appropriate since UUID, Recursive, and ExcludeHomeProject don't make a lot of sense in the generic ListOptions struct. I wonder if it should be called GroupContentsOptions though?
Sure, easy fix, done.

Ah, yes, done.

I've done this too.

Fixed.

SharedOptions→ListOptions:
+ // FIXME is this right?? We don't have options.UUID to cue the chooseBackend off + return conn.chooseBackend(conn.cluster.ClusterID).GroupShared(ctx, options)
I think this should be
return conn.chooseBackend(options.ClusterID).GroupShared(ctx, options)
Can we drop the "Kind" fields?
I've done this too.
Subtle Go trap here, in lib/controller/router/response.go. It's unsafe to append() to a slice that you don't own, like tmp["items"]. If the existing slice's backing array already has enough space, append() will use that instead of creating a new slice, so you might be overwriting stuff that's owned by other code. IIRC the resulting bug was hard to track down when we had one. You can avoid it by starting with a nil slice and appending everything.
(nits) you don't really need to check len(included)>0 -- can just let Go optimize "append nothing"... and since included/includedOK are only used long enough to append, they can be scoped smaller.
if included, ok := tmp["included"].([]interface{}); ok { items = append(items, included...) }
(nit) renaming itemsOK to isListResponse might make the if-else bit more obvious?
The rest LGTM. Nice readable commits, thanks!

17119-virtual-folder-from-query @ c869babec LGTM -- only nit is that this doesn't really need to be inside the "for _, slice ..." loop:
if opts.Count == "none" { delete(tmp, "items_available") }
Harmless at runtime, but maybe worth fixing for clarity.

Updated by Tom Clegg over 3 years ago
doc/api/methods/groups.html.textile.liquid has "role means FIXME"
In doc/api/permission-model.html.textile.liquid, I think the 2nd sentence here was intended to explain that when an object's owner is a Group, that Group must have group_class="project". So I think this change is incorrect:
-Valid uuid types for @owner_uuid@ are "User" and "Group". For Group, the @group_class@ must be a "project". +Valid uuid types for @owner_uuid@ are "User" and "Group". For Group, the @group_class@ must be "filter", "project" or "role".
(Perhaps the "For Group" wording could be improved though.)
Maybe this should say "...or a project" instead of "another project" (and "filter group" instead of just "filter"):
+* A filter can be owned by a user or another project.
Also, the preceding line "A filter cannot own things" → "A filter group cannot own things"
The info in doc/user/topics/projects.html.textile.liquid seems a little out of place here. Most of the user guide is procedural ("here's how to do x" -- like "creating projects" on the "uploading data" page) but much of this page is more like API info.
Perhaps this would be better as a dedicated page ("Using virtual projects"?) showing how to create and use a filter group?
(The discussion about how "home project" and projects in general are implemented, which APIs can be used, etc., seems like it belongs in API docs, not user guide.)
The GroupContents func in lib/controller/rpc/conn.go should really be in localdb, not rpc. ("rpc" is a client-side thing for serializing API calls as http requests -- "localdb" is for API implementation.)
This will panic if respGroup.Properties["filters"] is nil/map/string:
+ if filters, ok := respGroup.Properties["filters"]; ok { + for _, f := range filters.([]interface{}) {
I think this would fix it:
+ if filters, ok := respGroup.Properties["filters"].([]interface{}); ok { + for _, f := range filters {
The case where an element of properties.filters is not an array seems like it should be an error, rather than ignore-and-log-warning.
These can panic -- seems worthwhile to use a two-value cast, and return an error if they aren't strings:
+ filter.Attr = tmp[0].(string) + filter.Operator = tmp[1].(string)
(...even though none of these things are expected to happen given RailsAPI validation)
Here, "options" is GroupContentsOptions, so it doesn't seem right to pass it to the "get group" endpoint (and passing "select" from the original query doesn't seem right either). Better to use respGroup, err := conn.GroupGet(ctx, arvados.GetOptions{UUID: options.UUID})
(which should become possible when the code moves to localdb).
+ var respGroup arvados.Group + err := conn.requestAndDecode(ctx, &respGroup, epGet, nil, options)
Likewise, once this moves to localdb, "pass through to RailsAPI" code can use something like "return conn.railsProxy.GroupContents(...)" instead of requestAndDecode.
The RailsAPI validation errors say the filters property must be an array of arrays, but it looks like omitting the filters key entirely is equivalent to an "everything" group (no filters at all). I'm inclined to require that to be spelled {"filters":[]}
-- that might help avoid things like {"Filters":[["uuid","=","x"]]}
being silently ignored.

Ran wb1 test against arvados 17119-add-filter-groups
branch at: developer-tests-workbench2: #333
It seems that all cypress tests are failing because:
- At file
src/store/context-menu/context-menu-actions.test.ts
- Line 137: This overwrites the one I added at line 93. I think it would be better to use the constants, just in case their value change in the future.
The linter doesn't allow duplicated keys on an object. It would be interesting to investigate why the app cannot be built when unit test linting fails, maybe we can add a ticket for that.

Some more comments:
- At file
src/store/context-menu/context-menu-actions.ts
- Line 208: I believe this kind of checks aren't necessary because of the static type checking that TypeScript offers.
- Lines 225-235: Indentation used here is 2 spaces instead of 4 as the rest of the codebase. Also, there's some conditional tree nesting that I think could be avoided by AND-ing some checks (I just find shallow conditional trees easier to follow).
- I created a filter group with a non-admin user and it appears under "Projects" on wb2's left side panel, but when I click on it, the breadcrumbs shows "Shared with me > group_uuid", shouldn't be showing the group under "Projects > ...."?
- Project's details panel show filters in an understandable way (not ideal, but usable) but the property editor doesn't know how to edit them (trying to remove one filter or adding one gives an api error), should we fix the property editor or disable the editing features on this kind of groups?
- I think filter groups should have a special icon, to avoid user confusion. Looking at what's available at https://material-ui.com/components/material-icons/, it seems that the one named "Pageview" could a good candidate, to avoid doing cumbersome icon composing.
- When I open the details panel on a filter group, the "Type" label says "Project" instead of "Group".
- When the filter group belongs to a user, it isn't editable (for example, its name cannot be changed). Is that on purpose?

Interesting - I had added that because the unit tests blew up; router was passed in as undefined. But since then I've added router in the mocked store, so you're right, it is no longer needed. Removed.
- Lines 225-235: Indentation used here is 2 spaces instead of 4 as the rest of the codebase. Also, there's some conditional tree nesting that I think could be avoided by AND-ing some checks (I just find shallow conditional trees easier to follow).
Indentation fixed (we should probably add a precommit hook?); and I combined the innermost 2 conditions into one.
- I created a filter group with a non-admin user and it appears under "Projects" on wb2's left side panel, but when I click on it, the breadcrumbs shows "Shared with me > group_uuid", shouldn't be showing the group under "Projects > ...."?
Ah, good catch! That was actually caused by a bug in the API server; filter groups were not being returned in the group contents API call for a user's home project. That's fixed in 29634bb07a1f3c9be44e34b24e71badc4b42a860 in the Arvados repository.
- Project's details panel show filters in an understandable way (not ideal, but usable) but the property editor doesn't know how to edit them (trying to remove one filter or adding one gives an api error), should we fix the property editor or disable the editing features on this kind of groups?
I've disabled it for now, we'll do a follow on story (#17490) to make these groups editable from wb2.
- I think filter groups should have a special icon, to avoid user confusion. Looking at what's available at https://material-ui.com/components/material-icons/, it seems that the one named "Pageview" could a good candidate, to avoid doing cumbersome icon composing.
Yes! Change made.
- When I open the details panel on a filter group, the "Type" label says "Project" instead of "Group".
Yeah, I had added a 'Group class' line underneath but it's better to just change the type, I've made that change.
- When the filter group belongs to a user, it isn't editable (for example, its name cannot be changed). Is that on purpose?
No, there is no real reason for that; the only thing that matters is that the list of contents of a filter group is not directly editable. I've changed filter groups themselves back to editable.
Ready for review at 407d1f609f40e8a7d21cf5846690b63706befaa4 on the 17119-support-filter-groups branch. Tests are at developer-tests-workbench2: #339 .

Looking really good! Here're a few additional comments:
- Right-clicking on the filter group gets a different context menu depending whether or not the app is displaying the filter group's contents.
- The
DataExplorer
component's Type column says 'Project' on filter groups, and the column filtering also doesn't include filter groups as an option. I think this could be added as another follow-up ticket, and not fixed in this one, but just wanted to mention it so we don't forget. - One "editable project" action that I think should be avoided is 'New project', as no subproject are allowed inside filter groups.

I also fixed a few more bugs:
- filter groups were not being listed in the side panel trees (except for under the home project)
- trash contents were not listed (fix on the arvados side)

Just one tiny observation :)
- At file
src/store/context-menu/context-menu-actions.test.ts
- Line 27,inFilterGroup
was replaced withreadonly
. Do you think it would be clearer to name the argument something likeforceReadonly
or similar? I think renaming it at least on the test case will be useful so that it doesn't get confused withisEditable
.
The rest LGTM! thanks.

I also fixed two bugs that were already present in the group contents endpoint before this work:- items_available:0 was being returned when count: none was requested (doc says it should not be)
- when count: none was requested with a specific offset, too many results were being returned (in a somewhat unpredictable manner)

In doc/api/permission-model.html.textile.liquid, "role" should be "filter group":
+* A filter group cannot own things (cannot appear in @owner_uuid@). Putting a role in an @owner_uuid@ field is an error.
This would be safer as Index("-j7d0g-")!=5
, accounting for the case where someone uses j7d0g as a cluster ID:
if strings.Index(options.UUID, "j7d0g") != 6 { return conn.railsProxy.GroupContents(ctx, options) }
The case where an element of properties.filters is not an array seems like it should be an error, rather than ignore-and-log-warning.
I made that change.
OK, "properties":{"filters":[1]}
is covered (returns an error), but now I'm noticing that "properties":{"filters":"bogus"}
or "properties":{}
seems to return all visible items. That should probably cause an error too, right? (That change would also help un-pyramid the "if filters, ok := ...; ok {"
block.)
I'm finding the items_available changes in groups_controller pretty hard to follow, primarily because the existing code is so hard to follow. I think I'm getting that when count==none, we still do various things to calculate a value for @items_available
, but it's hard to make any sense of what the value actually means, which doesn't matter, because it isn't returned to the caller, because application_controller doesn't copy that instance variable into the response. As long as it works well enough to adjust @offset
on each klass iteration, we're ok.
One new mystery is why this has the "|| 0"
part -- isn't countless_items_available always a number at this point?
klass_items_available = countless_items_available || 0
Come to think of it, isn't this
if params['count'] == 'none' # The call to object_list below will not populate :items_available in # its response, because count is disabled. Save @objects length (does # not require another db query) so that @offset (if set) is handled # correctly. countless_items_available = @objects.length end ... if params['count'] != 'none' klass_items_available = klass_object_list[:items_available] || 0 else # klass_object_list[:items_available] is not populated klass_items_available = countless_items_available || 0 end
...equivalent to this?
klass_items_available = klass_object_list[:items_available] || @objects.length
Or maybe it's best to just walk away slowly...
Rest LGTM, thanks.

Oh! Good catch, fixed.
This would be safer as
Index("-j7d0g-")!=5

Right! Fixed.
The case where an element of properties.filters is not an array seems like it should be an error, rather than ignore-and-log-warning.
I made that change.
OK,
"properties":{"filters":[1]}

Hmm, I'm surprised, those are already caught by the validation afaict:
$ arv group create --group '{"group_class":"filter"}' Error: request failed: http://localhost:8004/arvados/v1/groups: 422 Unprocessable Entity: Properties filters property missing, it must be an array of arrays, each with 3 elements (req-13otv8ii5ojs21c86zai) $ arv group create --group '{"group_class":"filter","properties":{}}' Error: request failed: http://localhost:8004/arvados/v1/groups: 422 Unprocessable Entity: Properties filters property missing, it must be an array of arrays, each with 3 elements (req-14rceola0knocnbxo9q9) $ arv group create --group '{"group_class":"filter","properties":{"filters":"bogus"}}' Error: request failed: http://localhost:8004/arvados/v1/groups: 422 Unprocessable Entity: Properties filters property must be an array of arrays, each with 3 elements (req-ej0sxzk8y2v1xrtnb3dc)
The only one that still works is an empty set of filters, but that seems ok, that's the way to make a "filter group that shows everything":
$ arv group create --group '{"group_class":"filter","properties":{"filters":[]}}' { "created_at":"2021-03-30T16:31:39.806186579Z", "delete_at":null, "description":null, "etag":"b1kab85vdbbf09zvopgzeue58", "group_class":"filter", "href":"/groups/xxxx1-j7d0g-d2za9npzui7nidi", "is_trashed":false, "kind":"arvados#group", "modified_at":"2021-03-30T16:31:39.802918000Z", "modified_by_client_uuid":"xxxx1-ozdt8-cx642dwrzaqnoj0", "modified_by_user_uuid":"xxxx1-tpzed-etyzf2ixjtvj7fh", "name":"xxxx1-j7d0g-d2za9npzui7nidi", "owner_uuid":"xxxx1-tpzed-etyzf2ixjtvj7fh", "properties":{ "filters":[] }, "trash_at":null, "uuid":"xxxx1-j7d0g-d2za9npzui7nidi", "writable_by":[ "xxxx1-tpzed-etyzf2ixjtvj7fh", "xxxx1-tpzed-etyzf2ixjtvj7fh" ] }

Yes that is superfluous, I removed it.

Not quite - the call to object_list changes @objects, and @objects.length is changed by it. That's why I had to introduce the `countless_items_available` variable.
Or maybe it's best to just walk away slowly...
Yeah... I'm inclined to do that to avoid introducing new bugs. That function is hairy.
Rest LGTM, thanks.
