Queries for multiple specific articles are limited in size because of limits on the number of bound query parameters.
Currently this limit is somewhat arbitrarily set at 50, but it may increase.
Historically controllers would be responsible for chunking input, but this will present problems when the expected output is a result set, and of course the maintenance burden increases as the number of controllers increases.
This commit transfers the burden to the data model, and consequently introduces a ResultAggregate class which collects chunked result sets (currently only for articleList).
In the course of making these changes the mock Result class was also largely rewritten, fixing many bugs with it.
This commit does not modify the controllers nor their tests; this will be done in a subsequent commit.
- Result sets are now single-use; this is required for PDO drivers (PDO result sets are not rewindable)
- Change savepoint exceptions to be simple database exceptions; codes remain the same
TTRSS' getFeedTree operation references the URLs of icons included with the software. These icons are from the Silk icon set (see README in this commit), which is compatible with our license, so we simply use them as well.
This has the side-effect of removing the ability to reset a feed's title by passing null explicitly. As a non-standard behaviour it was simpler to just remove it.
This method provides generalized, consistent type casting more versatile than PHP's basic type juggling while hiding the significant complexity in achieving this.
While this commit does not change any existing code to use the new method, the intent is for both API handlers and database drivers to use the same basic rules for type conversion while still allowing for differing failure modes.
Also consolidated article star counting into a generic articleCount function which accepts a context.
This may lead to slight efficiency losses in either listing or marking (and more significant ones in counting starred), but the advantages of centralized context handling are significant with the future addition of labels and the need to count articles under various future contexts in TTRSS.
- Backend functions for adding, listing, removing, and editing (renaming) labels currently implemented
- TTRSS functions for adding (fixes #96), removing (fixes #97), and renaming (fixes #98) labels currently implemented
