DEBUGGED AND DIAGNOSED 2015-08-04. A bug showed up in the Landscapes DB which I think is generic: when a record contains two different one-to-many fields which link to the same table at one remove, editing a record can result in the creation of more links than should be created. It looks as though for each table which is linked through the same set of foreign keys, a new entry is created, causing there to be links that did not previously exist, generated through the save operation. This must be fixed. I've worked around it by removing one of the links in the owners table in that db (to sellers).

...but I have a bug I can't seem to figure out in the handling of results paging.

Spreadsheet generation is painfully slow and often runs out of memory or time. This is understandable given the number of queries taking place for complex table relationships, but I've managed to improve it substantially. I'm also working on speeding up retrieval for regular display, and I have a function written but not tested yet (db_recordList.php populateFromDb2). Ultimately, though, a massive set of joins is probably going to have to be done in the initial single query, making it absolutely huge but having it run only once, and then the non-standard db fields (lookups, one-to-manys etc.) will have to figure out parsing those results.

This has been needed for a while, and now it's essential in VPN so I've added it: you can put this into a text field:
^$
and it will search for records which have nothing or just space in those fields.
That means the VPN folks can do that with the Images field in the Poems table and find all the records which don't have page-images; then an explanation can be added in their new Page-image notes field.

Needs a bit more documentation, and there may be a need to make the width configurable (it's set to 200px right now), but it's working for MdhLinkField and MdhLinkSetField.
More fun working on this sort of thing at home with no interruptions. :-)

Basically done for the linksetfield, although I want to add an if clause that restricts it to only links which end with image file extensions. Then I need to port the same feature to the single link field.

Minor task that's been on my todo list for ages. This makes it simpler to maintain the instructions for a specific project distinct from the base instructions. Also deleted obsolete search_instructions file and tested.

JS-R reported a bug in the JSRDocs db, which took some time to figure out. I updated the server code to the latest version of the source, and then fixed some JS warnings, none of which was causing the problem. Eventually it turned out that there was a character 0x10 in one of the text fields; it's not allowed in XML, so it was causing Firefox to gack on any search results containing that record.
Not sure how it got in there, and not sure either how to protect against it; perhaps I need to add another component to the data sanitization code.

GN's current project is storing data in decimal format, so I've added a new field type to handle this, mapping to the SQL Decimal field (which is also supported in Postgres). Updated the sandbox db and tested it -- seems to work fine -- and regenerated the documentation.

Cleaned out any project-specific stuff (except for the sample project), removed all doxygen-generated files from SVN, and regenerated all docs, after installing all the required libraries locally. I can now generate docs OK by running doxywizard, then loading the Doxygen file and running it; to get a PDF, I switch to docs/latex and run make refman.pdf.
