  • Happy New Year CubicWeb !

    2016/01/25 by Nicolas Chauvat

    This CubicWeb blog that has been asleep for some months, whereas the development was active. Let me try to summarize the recent progress.

    CubicWeb 3.21

    CubicWeb 3.21 was published in July 2015. The announce was sent to the mailing list and changes were listed in the documentation.

    The main goal of this release was to reduce the technical debt. The code was improved, but the changes were not directly visible to users.

    CubicWeb 3.22

    CubicWeb 3.22 was published in January 2016. A mail was sent to the mailing list and the documentation was updated with the list of changes.

    The main achievements of this release were the inclusion of a new procedure to massively import data when using a Postgresql backend, improvements of migrations and customization of generic JSON exports.

    Roadmap and bi-monthly meetings

    After the last-minute cancellation of the may 2015 roadmap meeting, we failed to reschedule in june, the summer arrived, then the busy-busy end of the year... and voilà, we are in 2016.

    During that time, Logilab has been working on massive data import, full-js user interfaces exchanging JSON with the CubicWeb back-end, 3D in the browser, switching CubicWeb to Python3, moving its own apps to Bootstrap, using CubicWeb-Pyramid in production and improving management/supervision, etc. We will be more than happy to discuss this with the rest of the (small but strong) CubicWeb community.

    So let's wish a happy new year to everyone and meet again in March for a new roadmap session !

  • CubicWeb roadmap meeting on January 8th, 2015

    2015/01/05 by Nicolas Chauvat

    The Logilab team holds a roadmap meeting every two months to plan its CubicWeb development effort. The previous roadmap meeting was in November 2014.

    Here is the report about the January 8th, 2015 meeting.

    Christophe de Vienne (Unlish) and Aurélien Campéas (self-employed) joined us to express their concerns and discuss the future of CubicWeb.

    Versions

    Version 3.18

    This version is stable but old and maintained (current is 3.18.7).

    Version 3.19

    This version is stable and maintained (current is 3.19.8).

    Version 3.20

    This version has been released a few days ago. It has not been deployed on production systems yet.

    Its main features are:

    • virtual relations: a new ComputedRelation class can be used in schema.py; its rule attribute is an RQL snippet that defines the new relation.

    • computed attributes: an attribute can now be defined with a formula argument (also an RQL snippet); it will be read-only, and updated automatically.

      Both of these features are described in CWEP-002, and the updated "Data model" chapter of the CubicWeb book.

    • cubicweb-ctl plugins can use the cubicweb.utils.admincnx function to get a Connection object from an instance name.

    • new 'tornado' wsgi backend

    • session cookies have the HttpOnly flag, so they're no longer exposed to javascript

    • rich text fields can be formatted as markdown

    • the edit controller detects concurrent editions, and raises a ValidationError if an entity was modified between form generation and submission

    • cubicweb can use a postgresql "schema" (namespace) for its tables

    • cubicweb-ctl configure can be used to set values of the admin user credentials in the sources configuration file

    For details read list of tickets for CubicWeb 3.20.0.

    We would have loved to integrate the pyramid cube in this release, but the debian packaging effort needed by the pyramid stack is quite big and is acceptable if we target jessie only (at decent price).

    Version 3.21

    For now, the roadmap for 3.21 is still the complete removal of the dbapi, the merging of Connection and ClientConnection.

    Integrate the pyramid cube to provide the pyramid command if the pyramid framework can be imported.

    Integration of CWEP-003 (FROM clause for RQL) and CWEP-004 (cubes as standard python packages) is being discussed.

    Version 4.0

    We expect to accelerate development of CubicWeb 4, which exact roadmap is still to be discussed, but we may already want:

    • be pyramid-based (remove twisted, auth management, etc.),
    • do not have anything left of old dbapi and ClientConnection,
    • integrate squareui as main (and only) web-ui "template" or remove web generation (almost) completely from cubicweb-core and provide it only through the cube system.

    Agenda

    Next roadmap meeting will be held at the beginning of march 2015 at Logilab. Interested parties are invited to get in touch.

    Open Discussions

    Refactoring the documentation

    Christophe de Vienne suggested to completely revamp the documentation and intends to lead this effort.

    Training material

    Aurélien Campéas asks if Logilab would be willing to share its training material under a free license to help interested parties organize and sell trainings.

    Towards making squareui the default rendering engine for cubicweb

    We are expecting to be able to use squareui/bootstrap as "rendering engine" for our forge applications (like http://www.cubicweb.org and http://www.logilab.org) as soon as possible. However to achieve to goal, there are still too many "visual bugs", some of which may require a discussion.

    Among others:

    • put the ctxtoolbar component in the <nav> div
    • each box component should have an icon (what API for this?)
    • we cannot easily make the left column of the main template responsive-aware (requires to change the html flow), so it's probably best to take inspiration from things like http://wrapbootstrap.com/preview/WB0N89JMK
    • facet boxes are a mess, there is no simple solution to have a "smart layout"

    Migration

    • AppObjects should not be loaded by default
    • Have a look at Alembic the migration tool for SQLAlchemy and take inspiration from there.

  • CubicWeb roadmap meeting on September 4th, 2014

    2014/09/01 by Nicolas Chauvat

    The Logilab team holds a roadmap meeting every two months to plan its CubicWeb development effort. The previous roadmap meeting was in July 2014.

    Here is the report about the September 4th, 2014 meeting. Christophe de Vienne (Unlish) and Dimitri Papadopoulos (CEA) joined us to express their concerns and discuss the future of CubicWeb.

    Versions

    Version 3.17

    This version is stable but old and maintainance will continue only as long as some customers will be willing to pay for it (current is 3.17.16 with 3.17.17 in development).

    Version 3.18

    This version is stable and maintained (current is 3.18.5 with 3.18.6 in development).

    Version 3.19

    This version is stable and maintained (current is 3.19.3 with 3.19.4 in development).

    Version 3.20

    This version is under development. It will try to reduce as much as possible the stock of patches in the state "reviewed", "awaiting review" and "in progress". If you have had something in the works that has not been accepted yet, please ready it for 3.20 and get it merged.

    It should still include the work done for CWEP-002 (computed attributes and relations).

    For details read list of tickets for CubicWeb 3.20.0.

    Version 3.21

    Removal of the dbapi, merging of Connection and ClientConnection, CWEP-003 (adding a FROM clause to RQL).

    Version 4.0

    When the work done for Pyramid will have been tested, it will become the default runner and a lot of things will be dropped: twisted, dead code, ui and core code that would be better cast into cubes, etc.

    This version could happen early in 2015.

    Cubes

    New cubes and libraries

    CWEPs

    Here is the status of open CubicWeb Evolution Proposals:

    CWEP-0002 full-featured implementation, to be merged in 3.20

    CWEP-0003 patches sent to the review. . Champion will be adim.

    Work in progress

    PyConFR

    Christophe will try to present at PyConFR the work he did on getting CubicWeb to work with Pyramid.

    Pip-friendly source layout

    Logilab and Christophe will try to make CubicWeb more pip/virtualenv-friendly. This may involve changing the source layout to include a sub-directory, but the impact on existing devs is expected to be too much and could be delayed to CubicWeb 4.0.

    Pyramid

    Christophe has made good progress on getting CubicWeb to work with Pyramid and he intends to put it into production real soon now. There is a Pyramid extension named pyramid_cubicweb and a CubicWeb cube named cubicweb-pyramid. Both work with CubicWeb 3.19. Christophe demonstrated using the debug toolbar, authenticating users with Authomatic and starting multiple workers with uWSGI.

    Early adopters are now invited to jump in and help harden the code!

    Agenda

    Logilab's next roadmap meeting will be held at the beginning of november 2014 and Christophe and Dimitri were invited.

  • CubicWeb roadmap meeting on July 3rd, 2014

    2014/06/26 by Nicolas Chauvat

    The Logilab team holds a roadmap meeting every two months to plan its CubicWeb development effort. The previous roadmap meeting was in May 2014.

    Here is the report about the July 3rd, 2014 meeting. Christophe de Vienne (Unlish) and Dimitri Papadopoulos (CEA) joined us to express their concerns and discuss the future of CubicWeb.

    Versions

    Version 3.17

    This version is stable but old and maintainance will continue only as long as some customers will be willing to pay for it (current is 3.17.15 with 3.17.16 in development).

    Version 3.18

    This version is stable and maintained (current is 3.18.5 with 3.18.6 in development).

    Version 3.19

    This version was published at the end of April and has now been tested on our internal servers. It includes support for Cross Origin Resource Sharing (CORS) and a heavy refactoring that modifies sessions and sources to lay the path for CubicWeb 4.

    For details read the release notes or the list of tickets for CubicWeb 3.19.0. Current is 3.19.2

    Version 3.20

    This version is under development. It will try to reduce as much as possible the stock of patches in the state "reviewed", "awaiting review" and "in progress". If you have had something in the works that has not been accepted yet, please ready it for 3.20 and get it merged.

    It should still include the work done for CWEP-002 (computed attributes and relations.

    For details read list of tickets for CubicWeb 3.20.0.

    Version 3.21 (or maybe 4.0?)

    Removal of the dbapi, merging of Connection and ClientConnection, CWEP-003 (adding a FROM clause to RQL).

    Cubes

    Cubes published over the past two months

    New cubes

    • cubicweb-frbr: Cube providing a schema based on FRBR entities
    • cubicweb-clinipath
    • cubicweb-fastimport

    CWEPs

    Here is the status of open CubicWeb Evolution Proposals:

    CWEP-0002 only missing a bit of migration support, to be finished soon for inclusion in 3.20.

    CWEP-0003 has been reviewed and is waiting for a bit of reshaping that should occurs soon. It's targeted for 3.21.

    New CWEPs are expected to be written for clarifying the API of the _cw object, supporting persistent sessions and improving the performance of massive imports.

    Work in progress

    Design

    The new logo is now published in the 3.19 line. David showed us his experimentation that modernize a forge's ui with a bit of CSS. There is still a bit of pressure on the bootstrap side though, as it still rely on heavy monkey-patching in the cubicweb-bootstrap cube.

    Data import

    Also, Dimitry expressed is concerns with the lack of proper data import API. We should soon have some feedback from Aurelien's cubicweb-fastimport experimentation, which may be an answer to Dimitry's need. In the end, we somewhat agreed that there were different needs (eg massive-no-consistency import vs not-so-big-but-still-safe), that cubicweb.dataimport was an attempt to answer them all and then cubicweb-dataio and cubicweb-fastimport were more specific responses. In the end we may reasonably hope that an API will emerge.

    Removals

    On his way to persistent sessions, Aurélien made a huge progress toward silence of warnings in the 3.19 tests. dbapi has been removed, ClientConnection / Connection merged. We decided to take some time to think about the recurring task management as it is related to other tricky topics (application / instance configuration) and it's not directly related to persistent session.

    Rebasing on Pyramid

    Last but not least, Christophe demonstrated that CubicWeb could basically live with Pyramid. This experimentation will be pursued as it sounds very promising to get the good parts from the two framework.

    Agenda

    Logilab's next roadmap meeting will be held at the beginning of september 2014 and Christophe and Dimitri were invited.

  • Logilab's roadmap for CubicWeb on May 15th, 2014

    2014/05/21 by Nicolas Chauvat

    The Logilab team holds a roadmap meeting every two months to plan its CubicWeb development effort. Here is the report about the May 15th, 2014 meeting. The previous report posted to the blog was the march 2014 roadmap.

    Versions

    Version 3.17

    This version is stable but old and maintainance will continue only as long as some customers will be willing to pay for it (current is 3.17.15).

    Version 3.18

    This version is stable and maintained (current is 3.18.4).

    Version 3.19

    This version was published at the end of April. It includes support for Cross Origin Resource Sharing (CORS) and a heavy refactoring that modifies sessions and sources to lay the path for CubicWeb 4.

    For details read the release notes or the list of tickets for CubicWeb 3.19.0.

    Version 3.20

    This version is under development. It will try to reduce as much as possible the stock of patches in the state "reviewed", "awaiting review" and "in progress". If you have had something in the works that has not been accepted yet, please ready it for 3.20 and get it merged.

    It should also include the work done for CWEP-002 (computed attributes and relations) and the merging of Connection and ClientConnection if it happens to be simple enough to get done quickly (in case the removal of dbapi would really help, this merging will wait for 3.21).

    For details read list of tickets for CubicWeb 3.20.0.

    Version 3.21 (or maybe 4.0?)

    Removal of the dbapi and merging of CWEP-003 (adding a FROM clause to RQL).

    Cubes

    Here is a list of cubes that had versions published over the past two months: accidents, awstats, book, bootstrap, brainomics, cmt, collaboration, condor, container, dataio, expense, faq, file, forge, forum, genomics, geocoding, inlineedit, inventory, keyword, link, mailinglist, mediaplayer, medicalexp, nazcaui, ner, neuroimaging, newsaggregator, processing, questionnaire, rqlcontroller, semnews, signedrequest, squareui, task, testcard, timesheet, tracker, treeview, vcsfile, workorder.

    Here are a the new cubes we are pleased to announce:

    rqlcontroller receives via a POST a list of RQL queries and executes them. This is a way to build web services.

    wsme is helping build a web service API on top of a CubicWeb database.

    signedrequest is a simple token based authentication system. This is a way for scripts or callback urls to access an instance without login/pwd information.

    relationwidget is a widget usable in forms to edit relationships between objects. It depends on CubicWeb 3.19.

    searchui is an experiment on adding blocks to the list of facets that allow building complex RQL queries step by step by clicking with the mouse instead of directly writing the RQL with the keyboard.

    ckan is using the REST API of a CKAN data portal to mirror its content.

    CWEPs

    Here is the status of open CubicWeb Evolution Proposals:

    CWEP-0002 is now in good shape and the goal is to have it merged into 3.20. It lacks some documentation and a migration script.

    CWEP-0003 has made good progress during the latest sprint, but will need a thorough review before being merged. It will probably not be ready for 3.20 and have to wait for 3.21.

    New CWEPs are expected to be written for clarifying the API of the _cw object, supporting persistent sessions and improving the performance of massive imports.

    Visual identity

    CubicWeb has a new logo that will appear before the end of may on its revamped homepage at http://www.cubicweb.org

    Last but not least

    As already said on the mailing list, other developers and contributors are more than welcome to share their own goals in order to define a roadmap that best fits everyone's needs.

    Logilab's next roadmap meeting will be held at the beginning of july 2014.

  • Logilab's roadmap for CubicWeb on March 7th, 2014

    2014/03/10 by Nicolas Chauvat

    The Logilab team holds a roadmap meeting every two months to plan its CubicWeb development effort. Here is the report about the Mar 7th, 2014 meeting. The previous report posted to the blog was the january 2014 roadmap.

    Version 3.17

    This version is stable but old and maintainance will stop in a few weeks (current is 3.17.13 and 3.17.14 is upcoming).

    Version 3.18

    This version is stable and maintained (current is 3.18.3 and 3.18.4 is upcoming).

    Version 3.19

    This version is about to be published. It includes a heavy refactoring that modifies sessions and sources to lay the path for CubicWeb 4.

    For details read list of tickets for CubicWeb 3.19.0.

    Version 3.20

    This version will try to reduce as much as possible the stock of patches in the state "reviewed", "awaiting review" and "in progress". If you have had something in the works that has not been accepted yet, please ready it for 3.20 and get it merged.

    It should also include the work done for CWEP-002 (computed attributes and relations) and CWEP-003 (adding a FROM clause to RQL).

    For details read list of tickets for CubicWeb 3.20.0.

    Cubes

    Here is a list of cubes that had versions published over the past two months: addressbook, awstats, blog, bootstrap, brainomics, comment, container, dataio, genomics, invoice, mediaplayer, medicalexp, neuroimaginge, person, preview, questionnaire, securityprofile, simplefacet, squareui, tag, tracker, varnish, vcwiki, vtimeline.

    Here are a the new cubes we are pleased to announce:

    collaboration is a building block that reuses container and helps to define collaborative workflows where entities are cloned, modified and shared.

    Our priorities for the next two months are collaboration and container, then narval/apycot, then mercurial-server, then rqlcontroller and signedrequest, then imagesearch.

    Mid-term goals

    The work done for CWEP-0002 (computed attributes and relations) is expected to land in CubicWeb 3.20.

    The work done for CWEP-0003 (explicit data source federation using FROM in RQL) is expected to land in CubicWeb 3.20.

    Tools to diagnose performance issues would be very useful. Maybe in 3.21 ?

    Caching session data would help and some work was done on this topic during the sprint in february. Maybe in 3.22 ?

    WSGI has made progress lately, but still needs work. Maybe in 3.23 ?

    RESTfulness is a goal. Maybe in 3.24 ?

    Maybe 3.25 will be in fact 4.0 ?

    Events

    A spring sprint will take place in Logilab's offices in Paris from April 28th to 30th. We invite all the interested parties to join us there!

    Last but not least

    As already said on the mailing list, other developers and contributors are more than welcome to share their own goals in order to define a roadmap that best fits everyone's needs.

  • CubicWeb sprint / winter 2014

    2014/02/12 by Nicolas Chauvat

    This sprint took place at Logilab's offices in Paris on Feb 13/14. People from CEA, Unlish, Crealibre and Logilab teamed up to push CubicWeb forward.

    We did not forget the priorities from the roadmap:

    • CubicWeb 3.17.13 and 3.18.3 were released, and CubicWeb 3.19 made progress
    • the branch about ComputedAttributes and ComputedRelations (CWEP-002) is ready to be merged,
    • the branch about the FROM clause (CWEP-003) made progress (the CWEP was reviewed and part of the resulting spec was implemented),
    • in order to reduce work in progress, the number of patches in state reviewed or pending-review was brought down to 243 (from 302, that is 60 or 20%, which is not bad).

  • CubicWeb using Postgresql at its best

    2014/02/08 by Nicolas Chauvat

    We had a chat today with a core contributor to Postgresql from whom we may buy consulting services in the future. We discussed how CubicWeb could get the best out of Postgresql:

    • making use of the LISTEN/NOTIFY mechanism built into PG could be useful (to warn the cache about modified items for example) and PgQ is its good friend;
    • views (materialized or not) are another way to implement computed attributes and relations (see CWEP number 002) and it could be that the Entities table is in fact a view of other tables;
    • implementing RQL as an in-database language could open the door to new things (there is PL/pgSQL, PL/Python, what if we had PL/RQL?);
    • Foreign Data Wrappers written with Multicorn would be another way to write data feeds (see LDAP integration for an example);
    • managing dates can be tricky when users reside in different timezones and UTC is important to keep in mind (unicode/str is a good analogy);
    • for transitive closures that are often needed when implementing access control policies with __permissions, Postgresql can go a long way with queries like "WITH ... (SELECT UNION ALL SELECT RETURNING *) UPDATE USING ...";
    • the fastest way to load tabular data that does not need too much pre-processing is to create a temporary table in memory, then COPY-FROM the data into that table, then index it, then write the transform and load step in SQL (maybe with PL/Python);
    • when executing more than 10 updates in a row, it is better to write into a temporary table in memory, then update the actual tables with UPDATE USING (let's check if the psycopg driver does that when executemany is called);
    • reaching 10e8 rows in a table is at the time of this writing the stage when you should start monitoring your db seriously and start considering replication, partition and sharding.
    • full-text search is much better in Postgresql than the general public thinks it is and recent developments made it orders of magnitude faster than tools like Lucene or Solr and ElasticSearch;
    • when dealing with complex queries (searching graphs maybe), an option to consider is to implement a specific data type, use it into a materialized view and use GIN or GIST indexes over it;
    • for large scientific data sets, it could be interesting to link the numpy library into Postgresql and turn numpy arrays into a new data type;
    • Oh, and one last thing: the object-oriented tables of Postgresql are not such a great idea, unless you have a use case that fits them perfectly and does not hit their limitations (CubicWeb's is_instance_of does not seem to be one of these).

    Hopin' I got you thinkin' :)

  • Logilab's roadmap for CubicWeb on January 9th, 2014

    2014/01/14 by Nicolas Chauvat

    The Logilab team holds a roadmap meeting every two months to plan its CubicWeb development effort. Here is the report about the Jan 9th, 2014 meeting. The previous report posted to the blog was the november 2013 roadmap.

    Version 3.17

    This version is stable and maintained (current is 3.17.11 and 3.17.12 is upcoming).

    Version 3.18

    This version was released on Jan 10th. Read the release notes or the details of CubicWeb 3.18.0.

    Version 3.19

    This version includes a heavy refactoring that modifies sessions and sources to lay the path for CubicWeb 4. It is currently the default development head in the repository and is expected to be released before the end of january.

    For details read list of tickets for CubicWeb 3.19.0.

    Version 3.20

    This version will try to reduce as much as possible the stock of patches in the state "reviewed", "awaiting review" and "in progress". If you have had something in the works that has not been accepted yet, please ready it for 3.20 and get it merged.

    For details read list of tickets for CubicWeb 3.20.0.

    Cubes

    The current trend is to develop more and more new features in dedicated cubes than to add more code to the core of CubicWeb. If you thought CubicWeb development was slowing down, you made a mistake, because cubes are ramping up.

    Here is a list of versions that were published in the past two months: timesheet, postgis, leaflet, bootstrap, worker, container, embed, geocoding, vcreview, trackervcs, vcsfile, zone, dataio, mercurial-server, queueing, questionnaire, genomics, medicalexp, neuroimaging, brainomics, elections.

    Here are a the new cubes we are pleased to announce:

    Bootstrap works and we do not create a new application without it.

    relationwidget provides a modal window to edit relations in forms (use uicfg to activate it).

    resourcepicker provides a modal window to insert links to images and files into structured text.

    rqlcontroller allows to use the INSERT, DELETE and SET keywords when sending RQL queries over HTTP. It returns JSON. Get used to it and you may forget about asking for specific web services in your apps, for it is a generic web service.

    imagesearch is an image gallery with facets. You may use it as a demo of a visual search tool.

    Mid-term goals

    A new repository was created to have all the CubicWeb Evolution Proposals in one place.

    CWEP-0002 is a work in progress about computed relations and computed attributes, or maybe more. It will be a focus of the next sprint and is targeted at CubicWeb 3.20.

    A new CWEP is expected about the adding FROM keyword to RQL to implement explicit data source federation. It will be a focus of the next sprint and is targeted at CubicWeb 3.21.

    Tools to diagnose performance issues would be very useful. Maybe in 3.22 ?

    Caching session data would help. Maybe in 3.23 ?

    WSGI has made progress lately, but still needs work. Maybe in 3.24 ?

    RESTfulness is a goal. Maybe in 3.25 ?

    Maybe 3.26 will be in fact 4.0 ?

    Events

    A sprint will take place in Logilab's offices in Paris around mid-february or at the end of april. We invite all the interested parties to join us there!

    Last but not least

    As already said on the mailing list, other developers and contributors are more than welcome to share their own goals in order to define a roadmap that best fits everyone's needs.

    Logilab's next roadmap meeting will be held at the beginning of march 2014.
