Abstract

When adding major new features to CKAN, a longer, more formal discussion will improve software design quality and documentation, better engage the wider community, and ensure the core team are up to date with latest developments.

I propose a formal process (CREP -- CKAN Revision and Enhancement Proposal) for making this happen.

The Problem

The current workflow for introducing major new features into CKAN is very informal, typically based around one person's great idea, which they've discussed with one or two other people in the team. The originator of the idea is typically the only person with access to all the input they've had through such discussions. Often, the only location of this information is in that person's head.

However, there is a lot of experience embodied in the CKAN community which should be drawn on before making large design decisions. This will lead to better software. Additionally, building consensus in the community around a proposal before implementation ensures positive community engagement and buy-in to new features, making them more likely to be a success.

We aren't great at documenting new features. Documentation after coding is complete is an unrewarding experience for most programmers. Requiring skeleton documentation before code is written is a good discipline that can form the basis of better documentation in the future (e.g. by a writer rather than a programmer).

Specification

Minor features don't require a CREP, and can just be entered in the issue tracking system as a bug or feature. As a rule of thumb, a feature is major if it will take more than a day to implement, or is likely to involve matters of opinion in its design.

A developer may decide that a CREP is too formal and long-winded. The decision to write a CREP is at at their discretion; however, new features MUST always be proposed via email, even if this is just a couple of sentences.

If a feature requires a CREP, the proposer should find a seconder for their idea. This sanity check step happens before a CREP is written to ensure at least the possibility of consensus on the CREP.

Next the proposer should write a CREP, starting by copying and pasting the ​template on the wiki into a new Trac ticket. This will be with a status of "new" and Type of "CREP". The proposer should notify the ​ckan-dev mailing list, and possibly the ​ckan-discuss list for less technical CREPs.

The draft can be discussed via email, verbally, or via the trac ticket. In any case, it is the proposer's responsibility to keep the CREP updated to reflect the current consensus.

Once consensus has been reached, the ticket should be marked with the "accepted" status and assigned to a CKAN release milestone.

When an accepted CREP has been implemented, it should be resolved as "fixed".

If no consensus can be reached on a draft CREP, or for some reason an accepted CREP doesn't get completed, it should be marked as or "wontfix".

If a completed CREP becomes obsolete, it should be marked as "invalid", with a note pointing to the obsoleting ticket(s)

Why do it this way

Given the distributed nature of the core team plus other volunteers, some kind of written procedure is necessary to ensure a fully documented and discussed proposal.

The idea of "Enhancement Proposals" which can be semi-formally proposed and discussed prior to implementation is common in the Open Source world (​PEPs, ​DEPs, ​PLIPs, to name three).

Existing historic proposals exist, called CEPs. The proposed system is called CREP (CKAN revision or enhancement proposal) to disambiguate it from the legacy proposals, and from the delicious fungus Boletus Edulis.

Giving a formal structure to the proposal is useful as it gives the community a means to identify a CREP that's not had sufficient thought or discussion. An informal email thread can easily be lost and important questions (such as backwards compatibility) overlooked. The use of the proposed template empowers any community member to ask the proposer to expand on rationale, deliverables, etc.

The structure chosen is somewhere between Debian's and Plone's. It aims to give a structure to the debate, a clear start at documentation, and also prompt some thinking about implementation and timescales.

All this policy about structure should not be construed as mandatory. In particular, the later fields in the CREP template regarding Implementation Plan may be omitted if the author doesn't find them helpful.

Some projects (e.g. Debian) keep their enhancement proposals in a versioning repository; others (e.g. Plone) keep them in an issue tracking system. Trac is proposed for CKAN because we already use it for small feature proposals and for team planning. It seems unlikely that change tracking on an individual CREP will be useful; a CREP that changes sufficiently from its original form should probably be marked "obselete" and a new CREP started. Using an issue tracking system also means we can easily track CREPs by state.

Backwards Compatibility

Some [​https://bitbucket.org/okfn/ceps/src/76b274888bcf/cep/ legacy enhancement proposals], called CEPs, have previously been started.

They are currently all marked as "active". Any which require discussion should be altered by the proposer to match the new CREP specification and submitted to trac. The original CEP should be updated with a banner at the top pointing a reader to the new CREP.

Any that are now obselete should be clearly marked as such in a banner at the top, pointing a reader to the trac for new CREPs.

Implementation plan

Deliverables

• This CREP, agreed
• Support for proposed statuses in Trac
• Canned reports for listing CREPs in Trac

Risks and mitigations

• That this CREP is agreed, but rarely acted on. This risk can be mitigated by nominating a CREP champion in the community or core team, whose job it is to say "where's the CREP for that?" and generally own the quality of CREPS

Abstract

The new harvester interface allows to create harvesters for different sources, but right now harvesters don't have many ways to describe and configure themselves. We need a way of allowing them to:

• Expose their type and other details so they can be used internally and on the UI.
• Define configuration settings for particular harvester instances.

The Problem

Harvester description

The current UI for adding and editing harvest sources is the same used in ckanext-dgu, and thus the 3 harvester types used in DGU to harvest various GEMINI realted sources are hardcoded in the form. The form will be migrated to a DGU-independent one, so we need the harvesters to provide all the necessary data. There is a current get_type method that returns the harvester type, but for make it compatible with the DGU forms, it returns a machine-readable string (e.g. "CSW Server"), making it error prone.

Arbitrary configuration

In the current implementation, when the harvest process is started, ckanext-harvest looks for all the available plugins that implement the IHarvester interface and calls the appropiate methods for the current stage (gather_stage,fetch_stage,import_stage). At these stages, harvesters have no way of applying arbitrary configuration options, so all harvesters of the same type behave on the same way. For instance, the CKAN harvester needs a way to define the API version to use when harvesting remote instances (Right now, the version 2 is hardcoded on the code).

Specification

Harvester description

Harvesters will need to provide the following information so the UI form can be built:

• name: machine-readable name (e.g. "waf"). This will be the value stored in the database, and the one used by ckanext-harvest to call the appropiate harvester.
• title: human-readable name (e.g. "Web Accessible Folder (WAF)"). This will appear in the form's select box.
• description: a description of what the harvester does (e.g. "A Web Accessible Folder (WAF) displaying a list of GEMINI 2.1 documents"). This will appear on the form as a guidance to the user.

The way to provide it will be an info method that all harvesters must implement, which will return a dictionary with the previous elements:

    {
        'name': 'csw',
        'title': 'CSW Server',
        'description': 'A server that implements OGC's Catalog Service 
                        for the Web (CSW) standard'
    }

Arbitrary configuration

As different harvesters will have very different needs, we need to provide a way to persist arbitrary configuration flags for each harvest source. The more flexible way given the current architecture in my opinion would be to store the configuration options as a JSON encoded object as a property of the harvest source (There already is an unused DB field called config in the database) (Maybe using JsonType??).

This will mean adding an extra field in the harvest source form to allow entering the configuration. This could be just a simple text field where users enter the JSON encoded object or a more clever mechanism (i.e an "Add a configuration flag" link that adds two new text fields for the key and value for each flag, and a mechanism to later build the JSON object). In any case, this should probably be hidden in an "Advance options" section.

Why do it this way

Harvester description

The info method would provide a single point to get all the information related to the harvester, and future properties could be added to the dictionary returned without having to modify the interface.

Arbitrary configuration

There is an already existing config field in the database, so we won't need to change the model. Harvesters could access the config object at any of the stages. Of course they could provide default values in their implementations so users don't need to enter them everytime.

Implementation plan

Deliverables

Risks and mitigations

The highest risk on the harvesters info method side is that harvester implementation don't offer one of the necessary properties (namely name and title). This could fire a warning when showing the UI form or using the CLI.

Abstract

Package Relationships have not taken off in the 18 months we've had them in the API. There are some issues with them and we need to spend more time improving them or consider getting rid of them.

The Problem

Original use cases are expressed here: #253 Here are comments about how we could handle these specific examples better:

1. groups of packages - maybe better with a custom tag?
2. fragment resources - soon to be covered by 'kind' resource field #957

3&5. derived resource - better to have some sort of resource relationship perhaps?

4. linked resource - again better to have some sort of resource relationship perhaps?

Outstanding issues needing serious effort to fix:

• #256 Editing them in Web UI (not done yet)
• #1288 Package edit/creation can't include 'relationships' field

Specification

Remove relationships from model, API, tests, Web UI. Data migration to remove from db.

Why do it this way

Getting frustrated having problems with the code, when it's not used much. Often asked about what it's for, but rarely used. Seems an overly complicated design.

Backwards Compatibility

Risks and mitigations

Risk: a customer suddenly wants this, and the new ways to relate resources are not in place yet.

Mitigation: discuss this decision thoroughly to make sure we are confident the use cases are not important. Discuss with team, ckan-discuss and specifically the LOD people who have some related packages on thedatahub.org.

Database for all CKAN instances upgraded to Postgres 8.4, but none of the eu machines were upgraded with the tools necessary to administer them.

Editing groups in forms doesn't work for me, with latest code from this morning:

1. Clean db
2. paster create-test-data
3. paster sysadmin create ​http://davidread.myopenid.com/
4. paster serve development.ini
5. In browser, log in to CKAN
6. Create new package: name=abc group=Roger's books
7. [Preview] - yes group appears
8. [Save] - shows package and group hasn't appeared ERROR
9. Check ​http://127.0.0.1:5000/api/rest/package/abc and reedit package it also doesn't appear here either.

Sometimes editing a package via api on dgu results in some countries being lost in geo coverage.

When IP address is used to identify non-logged in users (for example on create and editing of packages) it is always 127.0.0.1 when using a reverse proxy (standard deployment configuration on a production machine and used e.g. on ​http://www.ckan.net).

This could be corrected by using HTTP_X_FORWARDED_FOR when available.

Since we upgraded to new vdm (v0.4) which has built in purge support existing purge support looks to be broken. Should be reasonably easy to fix this.

Cost: 1h

Using REST interface you can list packages and groups without authorization being checked.

Can be fixed using more advanced query to check authz.

Suggested fields:

• id, name (username/profile name), openid, email, password, extras (JsonType?)
  • + current items: apikey, about, created)
  • current contents of name is usually openid and should migrate to openid field (could match based on starting with ​http://)
• May also want a fullname field (or perhaps that can

just go in extras - may be better to have its own field as useful to search on this )

Related changes (probably separate tickets):

• Improve user home page to include this additional information (and have it be editable)
• Use user 'name' (username) for home page links (rather than current user/<id>)
• Where we show lists of revisions, each revision author is now a link to the author's user page.

Related to ticket:136 and ticket:138.

Search of form: tags: ... behaves differently depending on whether there is a leading space:

• tags: postcode - tags found correctly but no packages found
• tags:postcode - tags incorrectly found but correct packages found

Let's fix this.

Cost: 0.5h

Only first tag is updated.

Package history page package/history/mypackagename

• "Revisions" is redundant
• "Compare" button is in a ridiculous place. It should be above/below (both) the table, but not *in* it!
• Ditto to overall "Recent Changes" page comments w.r.t. timestamps, GUIDs (ellipsis), and (if poss) author links.

Currently it is possible (v0.11) to have a PackageResource? object without a url. This should be impossible to do (either at creation time or via modification).

Dumping ground for various minor and miscellaneous items (mainly refactorings):rgrp

• controllers/tag.py: why does this not use lib/search.py (but controllers/packages.py search method does)?

done:

• lib/search.py: inheritance would be nicer than switching on entity in search (i.e. have SearchPackage?, SearchTag? etc)

e.g. Text on ckan.net home page:

"All material available under an /licenseopen license"

Also seen on the package edit page: "/user/loginClick here to sign in"

I believe this is due to the i18n additions from Benoit. Maybe needs new Genshi. Maybe best to work round in the meantime.

Presence of license_id field in JSON input show below breaks REST API (with weird error about int not being subscriptable as if license_id field is being subscripted).

Using normal license field does not cause breakage but has no effect.

(Also think we should remove license_id from the API since there is no guarantee this cross system compatible since locally generated on install).

Create a new package with a name 'blah' and resource format 'blah'. Hit preview. There is an error because of the lack of resource url, but in the resource input boxes, there are now four resources with format 'blah'.

When I edit a package on no.ckan.net with lots of extra fields, lots of them completely disappear.

Metastable branch.

These don't work.

On ckan.net there is this unchecked-in 'temporary hack'. It seems to be to do with foreign characters in search options. See what its doing and if necessary, put check it in.

Thanks to Friedrich for spotting this.

Currently a package's history page (/package/history/xyz) and related feed only shows changes to the core package i.e. ones which create a PackageResource?. This doesn't include changes to tags, extras and resources. These need to be added.

There is the complication that the 'diff' function doesn't currently work beyond PackageResource?. Unless this is quick and simple to fix, I suggest we let the diff remain slightly broken for now.

Rufus suggests alongside the existing methods:

pkg.all_revisions()
pkg.diff()

we have ones which also include the related objects (tags, extras, resources):

pkg.all_revisions_full()
pkg.diff_full()

You could have a function which returned these related objects. Ideas:

revobjlist = [ self, resources, extras ]
list of tuples: (revobj, changed_revobjs)
list of tuples: (revobj, {objtype: [changed_revobjs]})
tuple: (rev1, {Package: [ object_id, object_id], PackageTag: [object_id, object_id2] ...}

Expect to page through results.

Only page 1 is shown, all other pages fail to display.

Reproduce by searching for something common and browsing to the second page.

Deleted tags are visible on the /tag page and are searchable.

Delete tags are ones that were in use once and then discarded, so this includes ones which are not used on any packages any more, including misspelling, mistakes, and deprecated tags. It would makes sense to remove them.

Example tag that is viewed at /tag and searchable: ​http://ckan.net/tag/2rand[0

Bug report regarding getting revisions:

Getting revisons by ID (on the latest ID) GET "​http://test-hmg.ckan.net/api/search/revision?since_revision=44aac9b6-ba24-43a8-87a1-f6923dc523ff"

Returns a whole load of stuff (it's also quite slow - about 10 seconds)

I'm expecting it to return just an empty array - am I doing something wrong here - if so could you clarify correct use of the API?

GET "​http://test-hmg.ckan.net/api/search/revision?since_time=2010-04-30T23:45" Returns the empty string - I'd expect an empty array ie []

GET "​http://test-hmg.ckan.net/api/search/revision?since_time=2010-04-31T23:45" Returns an internal server error 500 - I think it should probably be "bad Request" 400 (the date is invalid)

If you search for unescaped characters such as '`' (backtick) in the URL in Chrome then you get a 500 error.

e.g. ​http://www.ckan.net/package/search?q=fjdkf2B%C2%B4gfhgfkgf{gpk fjdkf2B´gfhgfkgf{gpk

returns this exception:

Migration script 18 converts license "OKD Compliant::Local Authority Copyright with data.gov.uk rights" into "uklocalauthority-withrights" when it should be "localauth-withrights", according to the license service SoS 2. This causes clients difficulties looking it up.

Reproduction

Using the government form, create a new package with name 'test' and date released of '23/5/0210'. The result is a 500 error and 'Server Error' message.

Affects all versions of CKAN.

Why it's happening

The dates module is raising an exception on the invalid date when saving the date, which is not being caught. The exception should have been raised only during the earlier 'validation' step and that would be caught.

During tag autocompletion, clicking on a suggested tag doesn't trigger completion in the text box.

As a

CKAN client such as ScraperWiki

I want to

search for Package Resources, either by URL or other field, or just get them all. I want to be able to get all the resource's fields, such as URL.

Proposed implementation

Add resource search API at:

/api/search/resource

AND resource added to model API at:

api/rest/resource

(see ticket:358)

Functional differences from the ScraperWiki suggested patch:

• URL is not normalised

• URLs are not grouped

• All fields of the resource object are returned, not just the URL

• Package is identified by its ID, not name or full URL. (This is for consistency in the API - you can simple prepend '​http://ckan.net/package/' to the package ID)

This is to make our API more general, simple and consistent. It means that the ScraperWiki client has to do a bit more processing to get exactly what it needs. Is this ok?

Example search

POST

{"url": "scraperwiki.com/", "all_fields": 1}

to: /api/2/search/resource

returns JSON:

 [{"id": "a3dd8f64-9078-4f04-845c-e3f047125028",
   "package_id": "b8a325c8-af2a-43f3-8245-9db7d73dfbfe",
   "URL": "http://scraperwiki.com/lincolnshire-councillors", 
   "format": "CSV", 
   "Description": "Scrape of www.lincs.gov/councillors.pdf by ScraperWiki.",
   "hash": "", 
   "position": 2
 }]

Note use of package_id instead of package_name is something we're moving towards in the API, since names can change. When we've done ticket:341 then ckan.net/package/lincs-councillors will be a synonym of ckan.net/package/b8a325c8-af2a-43f3-8245-9db7d73dfbfe

Search Parameters

Key:  q
Description: Search all resource fields for the value

Key: url / description / format / 
Description: Search particular field for the value

Key: all_fields
Value: 0 or 1 (0 is default)
Description: If 1 (true), the full record of the package resource
(and it's package reference) are returned, rather than just the
PackageResource ID.

May also choose to introduce 'offset' and 'limit' to page through a large number of results.

JSONP achieved through API-wide parameter - see ticket:342

Search is case insensitive.

Original request

Hi, have attached a patch for adding a resource list api call. Have also added a JSONP compatible callback section, along the lines of #388.

Could also add a search version. Not sure what the best url would be for that though.

Haven't written a test as the structure seems to follow a functional spec. Is that document around somewhere?

Donovan

When you do a Package Search or query a Package Relationship in the API version 2, the responses have relationships which refer to packages by name, not by ID.

Whilst going through the API docs for the revision search API, it was noticed that the "Gdu" SoS doc doesn't match up. It returns revision IDs (perhaps this is useful to note in the spec?) so the format is probably not 'limitedstring'. Also, they appear to be ordered youngest first, not oldest as stated.

And in the revision model, it refers to 'simplestring' which it doesn't define - I guess the names should be 'limitedstring'?

Could this be checked out?

As a

SOLR instance

I want to

keep my search index of CKAN packages up-to-date

Implementation

• Using asynchronous event notifications
• Running in a separate process to CKAN

Sort out how we deal with dashes versus underscores in package names.

In 0.5 and 0.6 have been more oriented to getting file indexes working to support the convenience of using packages on disk directly. However we now need to go back to having a better central/default index and the best model for this is a simple db index using sqlite (which is now supported in the standard library).

NB: this is a retrospective ticket (been working on this for a couple of months)

Occasionally we seem to get revisions that are not connected to packages. These shouldn't appear, since all revisioned objects are linked to a package aren't they?

They appear on the 'Recently changed' list on the home page with an empty 'Packages' column.

I've just started writing the importer from cap.open.org.nz and was running an initial import of just the package name and titles. The packages were created however I received a 500 error in response:

"publish: New Zealand Coastline (new-zealand-coastline)" opening connection to nz.ckan.net... opened <- "POST /api/rest/package HTTP/1.1\r\nContent-Type: application/x-www-form-urlencoded\r\nConnection: close\r\nAuthorization: 81179ade-fa4a-4632-9b89-3d0c98bfc8b8\r\nContent-Length: 64\r\nHost: nz.ckan.net\r\n\r\n" <- "{\"name\":\"new-zealand-coastline\",\"title\":\"New Zealand Coastline\"}" -> "HTTP/1.1 500 Internal Server Error\r\n" -> "Date: Tue, 20 Jul 2010 10:20:35 GMT\r\n" -> "Server: Apache/2.2.9 (Debian) mod_wsgi/2.5 Python/2.5.2\r\n" -> "Vary: Accept-Encoding\r\n" -> "Content-Type: text/html; charset=iso-8859-1\r\n" -> "Cache-Control: proxy-revalidate\r\n" -> "Content-Length: 640\r\n" -> "Connection: close\r\n" -> "\r\n" reading 640 bytes... -> "<!DOCTYPE HTML PUBLIC \"-IETFDTD HTML 2.0EN\">\n<html><head>\n<title>500 Internal Server Error</title>\n</head><body>\n<h1>Internal Server Error</h1>\n<p>The server encountered an internal error or\nmisconfiguration and was unable to complete\nyour request.</p>\n<p>Please contact the server administrator,\n [no address given] and inform them of the time the error occurred,\nand anything you might have done that may have\ncaused the error.</p>\n<p>More information about this error may be available\nin the server error log.</p>\n<hr>\n<address>Apache/2.2.9 (Debian) mod_wsgi/2.5 Python/2.5.2 Server at nz.ckan.net Port 80</address>\n</body></html>\n" read 640 bytes Conn close

The server should not respond with a 500 error if the package was created.

This occurs when CKAN is run with mod_wsgi (not under paster).

This is because of a unicode header being creating in rest.py.
