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
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
- Database functions now accept any input, but throw typeViolation exceptions where appropriate instead of idMissing or subjectMissing
- Added unit tests for the new Misc\ValueInfo static class
- Added ValueInfo::id() method to centrally validate database IDs, and made use of it consistently
- Made use of PHP's filter_var() function where appropriate when validating or sanitizing input
- Made the NCN protocol handler reject most invalid IDs before handing off to method handlers
- Made NCN's feedUpdate and subscriptionMove methods return 422 on invalid input
- Adjusted several tests to handler type violations
- Specifying a non-integer parent no longer silently casts to 0 or 1
- Specifying a folder ID of 0 now always converts to null automatically
- Performing both a rename and move to root in the same operation no longer results in potential duplicates
- Calling folderSetProperties with an empty data array no peforms an update; it now returns false before the update call
- Modification timestamps are now actually updated when a folder is modified
- Constraint violation exceptions triggered by code (rather than the database) now print a message
- Renaming a folder or subscription to a non-string value (e.g. an array) throws an exception rather than silently casting
- Added tests to better cover all the above
- Centralized the normalization of integers and title strings into a new ValueInfo static class
