Problem:
"symfony/console": "2.3.*"
causes ./X setup:db
on a fresh install to display error message:
"The helper "question" is not defined."
Solution/Fix:
"symfony/console": "2.6.*"
The 'ids' format is currently marked as not implemented.
Desribed in spec as:
If 'ids', only include minimum information necessary in Agent, Activity, Verb and Group Objects to identify them. For anonymous groups this means including the minimum information needed to identify each member.
Get activity state API is getting "Access-Control-Allow-Origin" error issue
POST https://api.experience.at/activities/state?method=GET
quiz.html:1 XMLHttpRequest cannot load https://api.experience.at/activities/state?method=GET. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://mygpcommunity.com.au' is therefore not allowed access. The response had HTTP status code 500.
I think the activity objectTypes
are returned incorrectly. They always appear as objectType "Activity", even if they are of one of the other allowed Activity types
Example:
Statement: ee438260-59d9-489f-ad8a-59cedcf0f21c
POSTS an object
{
id: "e79cbe5e-be22-4ef9-b16d-0bd64f6a6fb8",
objectType: "StatementRef"
}
GET http://dev.experience.at/activities?activityId=e79cbe5e-be22-4ef9-b16d-0bd64f6a6fb8
however returns
{"id":"e79cbe5e-be22-4ef9-b16d-0bd64f6a6fb8","objectType":"Activity"}
The xAPI states that an Object can be of these types:
My understanding is that ONLY Activites
are to be stored in the activity profile api.
There is however a booby-trap. The objectType
param is optional for type Activity
, so it can be omitted on POST but needs to be identified as Acitivity
. The other types listed require the objectType
param according to the specs.
So the LRS needs IMO first to validate for an Activity this way:
objectType
param && objectType .value === 'Activity'
objectType
param is NOT set, but Object has a param id
with a valid IRI[Notes]
We are missing this response header:
The LRS MUST include the header "X-Experience-API-Consistent-Through", in ISO 8601 combined date and time format, on all responses to Statements requests, with a value of the timestamp for which all Statements that have or will have a "stored" property before that time are known with reasonable certainty to be available for retrieval. This time SHOULD take into account any temporary condition, such as excessive load, which might cause a delay in Statements becoming available for retrieval.
GET /statements
Here the params
{
agent:{
account: {
"homePage": "<url>",
"name": <name>"
}
},
verb: 'http://adlnet.gov/expapi/verbs/approved',
format: "canonical"
}
Query (decoded)
returns status 500 {"error_message":"Document has no method \"renderCanonical\""}
see also: https://github.com/Brightcookie/lxHive/search?utf8=%E2%9C%93&q=canonical
This seems to be missing indeed.

Hi,
I have gotten a fresh install going and I don't seem to be able to access /public . I've gone back over the installation steps and I followed them perfectly. I've also had a look through the Apache and PHP logs and then are no errors logged.
Any ideas of what may have gone wrong?
Thanks,
Zac

From other forums I think your server is not recognizing the 1.0.1 as the About i responding with a null !

TinCanPHP uses fopen for remote connection.
Opposite to our competitors we are returning always 404
for valid requests. this is due to a path issue, mainly caused by slim routing.
TCPHP sets the context option request_fulluri = 1
, which cannot be overwritten
https://github.com/RusticiSoftware/TinCanPHP/blob/master/src/RemoteLRS.php#L89
This changes the $_SERVER['REQUEST_URI']
request_fulluri = 0
creates $_SERVER['REQUEST_URI'] = '/statements'
request_fulluri = 1
creates $_SERVER['REQUEST_URI'] = 'http://myslrs.com/statements'
Slim2 doesn't consider this
$requestUri = $_SERVER['REQUEST_URI']; // <-- "/foo/bar?test=abc" or "/foo/index.php/bar?test=abc"
https://github.com/slimphp/Slim/blob/2.x/Slim/Environment.php#L131, comments are original
$requestUri becomes $env['PATH_INFO'], which eventually ** get's a trailing slash prefixed**
$env['PATH_INFO'] = '/' . ltrim($env['PATH_INFO'], '/'); // <-- Ensure leading slash
https://github.com/slimphp/Slim/blob/2.x/Slim/Environment.php#L148, comments are original
so we end up with a route like this, which creates a 404
:
// mind the first /!
/http://myslrs.com/statements
Bang!
As far as I can see this is not fixable with Slim2, except we are going to do some url rewriting on htaccess or apache, which leads to all kind of troubles with subdomains/subfolders etc...
We need to check if slim3 deals with this case. I 've seen they have added stream environment class but i think this is rather for consuming
According to RFC4122 these are valid representations of the same uuid:
e05aa883-acaf-40ad-bf54-02c8ce485fb0
E05AA883-ACAF-40AD-BF54-02C8CE485FB0
{e05aa883-acaf-40ad-bf54-02c8ce485fb0}
{E05AA883-ACAF-40AD-BF54-02C8CE485FB0}
urn:uuid:e05aa883-acaf-40ad-bf54-02c8ce485fb0
urn:uuid:E05AA883-ACAF-40AD-BF54-02C8CE485FB0
We are currently considering only 1) as valid. (Json schema)
While it is easy to correct the regex we need to make sure that all 4 are treated as 1 statement for all read/writes
I think it doesn't violate statement immutability when we accept all, but lowercasing on on smt storage. On all GET (incl extensions) we should lowercase and strip the request id as well.
affected
pure css cdn doesn't not support https (Error code: ssl_error_bad_cert_domain), so the css wont load
We need either to fetch it from a different cdn or include it locally.

This issue actually relates to a discussion we had about allowing LRS owners to plug-in their own theme/branding of OAuth, so maybe we tackle issue and enhancement in 0.9.1.

I am aware that this is largely addressed already in the development of the new release, however since progress lags behind I will solve this for the current
Under xApi -> xAPI introduction, it says:

Shouldn't it read

?
Further down, under 'Using the configuration files', 2 methods of overwriting YAML configuration files are mentiones, which are actually only one method 'Config.production.yml':
The defaults are in Config.yml, however you can override them in Config.production.yml or Config.production.yml files.
What would the second one be?
Under 'Development guidelines', it reads:
[...] and fix any bugs you might.
I assume 'you might find' is, what you mean, right? :-)
Hi,
Are there any plans to support PHP 7? You would need to switch to the new mongodb driver in order to do so, as the old legacy driver is not supported in PHP7:
http://stackoverflow.com/questions/34569112/using-legacy-mongodb-driver-with-php7
token is created always for first user in users collection, regardless which email selected
Custom response headers are not available within the XMLHttpRequest object (ajax) and thus cannot be evaluated.
Example:
The LRS MUST include the header "X-Experience-API-Consistent-Through"
This header is not currently not available to the (ajax) client via xhr.getAllResponseHeaders()
Research...
CORS allows only exposure a few response headers to be exposed by default
Cache-Control
Content-Language
Content-Type
Expires
Last-Modified
Pragma
the server needs to specifically expose any other header :
Authorization
header: 400 Bad RequestX-Experience-API-Version
(e.g 99.99.9
): 400 Bad request, X-Experience-API-Version is not supportedAuthorization
credentials (e.g. Authorization:Basic non-extising:user
): 400
or 401
(?)Added Jasmine tests ('Bad requests' section).
@sraka1 I wonder if we can include the creation of the file storage folders (including perms) during the installation or setup process. This seems to be a frequent stumbling block.
As a paradigm I suggest the filestore should be always required, regardless if the user switches the config to aws
or another adaptor. (writing cache files, like lock files, logs)
1. option: composer script
"scripts": {
"post-package-install": [
"php -r \"mkdir('./storage/files/',0770, true);\""
]
}
// 0770 recommended by https://www.drupal.org/node/244924
2. option during ./X
setup command via League\Flysystem
adapter
$config = Yaml::parse(<template-config.yml>);
$fs = API\Util\Filesystem::generateAdapter($config['filesystem']); //creates folder(s)
Option 1 is IMO the most elegant. I tested both on apache/linux however I am not too sure if it works well with other env. Thoughts?
specs: https://github.com/adlnet/xAPI-Spec/blob/1.0.2/xAPI.md#4162-contextactivities-property
a) It is allowed to post any of the types as a single activity instead an array:
Single Activity Objects are allowed as values so that 0.95 Statements will be compatible with 1.0.0.
b) but is is required always to return arrays of activities
The LRS MUST return every value in the contextActivities Object as an array, even if it arrived as a single Activity Object.
We do a) but store them as singles and fail on b) as we return the singles as we had stored them.
test: node test -g 'Context: contextActivities'
We should add a hint for multi-select options to the terminal output. See example for permissions
below. Currently it is not stated that you can select multiple values as comma-separated input.
$ ./X user:create
Please enter an e-mail: [email protected]
Please enter a password: ********
Please select which permissions you would like to enable (defaults to super). If you select super, all other permissions are also inherited:
[0] super
[1] statements/read
[2] statements/read/mine
[3] attachments
[4] state
[5] profile
[6] define
[7] all/read
[8] all
> 1,3,4
User successfully created!
Info:{
// user object
}
How about:
Please select which permissions you would like to enable (defaults to super). Separate multiple values with commas. If you select super, all other permissions are also inherited
As discussed, the temporary token workflow is currently broken.
https://github.com/Brightcookie/lxHive/wiki/Issuing-temporary-access-tokens
provide user agent profile id (better, the person object) as specified in the specs so it can be loaded straight away on application init
For apps to display. These are human data anyway.

because this is multiple choice and the way to list the choice items is to fetch the supported_auth_scopes in config file.
but the QuestionHelper.php -- line 119
foreach ($question->getChoices() as $key => $value) {
$messages[] = sprintf(" [<info>%-${width}s</info>] %s", $key, $value);
}
so we need to change the config file and find the other way to show the multiple choice items.
We are currently rejecting stored
timestamps when writing statements. However 1.0.2 and 1.0.3 have not this requirement. They both state only that an LRS MUST SET the stored
property.
While 1.0.2 doesn't consider the case explicitly, 1.0.3 elaborates this case.
The "stored" property MUST be set by the LRS; An LRS SHOULD validate and then MUST overwrite any value currently in the "stored" property of a Statement it receives.
The stored
property is also exempt from the statement immutability in both versions. So it is valid to overwrite them on receiving. There is also no such negative test case in both ADL test suites.
To me this makes sense, especially when LRS communicate with each other. There is no need to strip this property.
For reporting purposes we need to add some custom API for fetching statements and documents
Examples (this is a quick shot):
GET /plus/agents
// all agents within within the scope of my APIkey
GET /plus/acitivties?where={"key":"value"}
// a mongo query, within the scope of my APIkey
GET /plus/statements?mlimit=5&order=ASC
// mlimit == Mongo limit (not xAPI limit), returns first 5 smt, plus pagination
/plus/statements?key=result&where={"key":"value"} // a mongo query
/plus/statements?key=authority&where={"key":"value"} // a mongo query
/plus/statements?key=context&where={"key":"value"} // a mongo query
These queries should be available only for certain scopes - maybe we create a dedicated scope?
Learninglocker has a similar approach:
Submitted requests who are requiring eTags in xAPI 1.03. should not require this:
Currently any affected request are validated as 1.0.3, regardless of X-Experience-API-Version
header or supported version settings in the Config.yml
Endpoints:
/agents
/activities/state
/activities

ADL example of CORS PUT request: https://github.com/adlnet/xAPI-Spec/blob/1.0.3/xAPI.md#appendix-g-cross-domain-request-example
Since applications like storyline send in legacy mode and don't supply a version param we have in this case to revert to the minimal supported version as defined in config.yml

I've done a clean installation of lxHive on a Debian machine. All the required tools and configurations seems to be ok, but when I try to setup the DB I get the following error:

Do you have any idea of what could had gone wrong?

In order to create t token on needs first a valid user
./X user:create
./X auth:basic:create #use user.email to match
However frequently admins forget the first step or the email is typed wrong. In this case the script exists with an PHP Exception.
./X auth:basic:create
Please enter a name: asthon
Please enter a description: ashton developer
Please enter the expiration timestamp for the token (blank == indefinite):
Please enter enter the e-mail of the associated user: [email protected]

TODO
It is not clear to me which spec lxHive supports?
In the README.md are mentioned 2 different specs.
Is it 1.0.2 or 1.0.3?
With this the owner has full freedom to customize markup and content of the template and can also replace/extends css and js. Maybe we can even omit the config and do the check by default (for a defined user theme directory)
See also discussion in #8
Currently both modes logging into the same file.
I think this might be an issue with the JSON schema.

There are many changes to 1.0.3 which is still a working draft. We initially thought we can keep up with the changes but that proved not to be the case.
The current version of the specification is 1.0.2. 1.0.3 is currently being developed by the specification working group.
current Config:
xAPI.latest_version: 1.0.3
xApi.supported_versions: [1.0.3]
Task: Change default support to 1.0.2
in Config.yaml and docs and brand websites
@sraka1 I don't expect anything breaking with these changes? Users can still keep their 1.0.3 configs.
Invalid /statements multipart requests currently cause 500 errors when parsing the binary parts. See example below.
I think we need to implement a parser Validation layer where we catch the most common cases and respond with an xAPI compliant Bad request
error instead.
Example response with 500
{"error_message":"file_put_contents(\/www\/lxHive\/storage\/files\/): failed to open stream: Is a directory"
}
//reason: sha2 hash not found??
//500 errors and revealing internals in the message is not great.

With this method it would be possible to authenticate via client (form, middleware) without the redirection step to the Authorisation server.
