MySource Matrix Developer Newsletter Issue 24
Friday 20th May 2005
covers versions 3.4.2 stable, 3.5.0 development
News
Search Exact Phrase Matching
It was reported in last week's newsletter that exact phrase matching was being added to the MySource Matrix search engine. Further development work as uncovered problems with PostgreSQL text indexing that has resulted in this feature having to be postponed for PostgreSQL installs of MySource Matrix.
Oracle has a much advanced text indexing system, so exact phrase matching may be available to Oracle clients in the future. Custom exact phrase matching will be built for the BLIS project using Oracle, but this will not be available to other Oracle based clients without additional development work.
New Features
Metadata Thesaurus Field Improvements
Added to: 3.5.0 development
The thesaurus metadata field has been changed to allow an editor to select multiple terms for the field using the thesaurus browser. The metadata field can be configured to set a maximum number of terms that can be entered. Each selected term also shows the category lineage from the top of the thesaurus to help editors understand the context of the term when selecting additional fields.
It should be noted that the category lineage will only work correctly if the built-in "category" relationship is used to categorise terms in a thesaurus. Custom relationships cannot be used to determine lineage.
Backend Translation (stage 4)
Added to: 3.5.0 development
All remaining strings within MySource Matrix have now been translation enabled. The translation project now requires a full translation of the MySource Matrix strings to be completed in a language other than English. A script has been prepared to aid in this translation effort by combining all translation files into 4 main files. These 4 files can be given translated and returned back to us.
Advanced Asset Caching For Scripts
Added to: 3.5.0 development
The asset cache of the Asset Manager has been rewritten to offer more control on the number of assets that reside in memory. Once a loaded asset is not used anymore it will remain in memory until the cache size reaches a certain size.
The cache size is now defined by two new constants in the main configuration file: one for the scripts running from the command line (SQ_CONF_ASSET_CACHE_SIZE_CLI) and one for those running from the web server (SQ_CONF_ASSET_CACHE_SIZE_WEB). The default value is -1, a special value preventing the cache from unloading any assets no matter what size the cache has grown to. This emulates the existing functionality of MySource Matrix the best and should result in no unexpected problems for upgrades.
This update will help external scripts to execute many operations within MySource Matrix in one go without using an excessive amount of memory.
Although this modification is transparent for the rest of the MySource Matrix classes, the existing code will have to be modified to take advantage of this cache. Every call to getAsset() should be followed by a call to forgetAsset().
Note that this is not a permanent shared cache for all users like a frontend page content cache is. This cache relates to the loading and reuse of assets in a single script execution.
Editable Form Submissions
Added to: 3.5.0 development
Form submissions now have a details screen where you can edit the answers to questions, as long as those questions still exist in the form that created the submission. If the submitted value is no longer a valid value for the question you can leave it intact, or specify a new, valid, value. If new questions have been added to the form and they are required, you can still leave them blank when editing the submission. You can access the submission's details screen via the submission log screen of the form asset.
Planned Development
Search Page Dynamic Root Nodes
To be added to : 3.5.0 development
Estimated start date: already in development
Estimated end date : 25th May 2005
Asset listings have been able to accept dynamic root nodes for a while now. Search page is now getting the same functionality. This will allow you so send the search page the a list of asset IDs it should use as the root search nodes on the query string.

Notes:
Bug #638 (getAssetInfo fails when getting info for a large number of assets) was submitted by Marcus, but was marked as "Will not Fix". The bug relates to a condition where if you ask Matrix to give you information about more than 10,000 assets at a time, the database query will fail. The real cause of this problem is that the custom form submission listing is not paginated and so tries to load all 10,000 form submissions in one go. A feature request has been added to paginate this interface and stop this error from occurring.
