Problem/Motivation
If a module logs an error and one of the context are not convertible into a string, dblog the page crashes with an exception. To recover from this issue I have first truncated the dblog table and than cleared all caches as the truncate was not enough.
Proposed resolution
LogMessageParser::parseMessagePlaceholders(), which is called by the dblog and syslog loggers, should exclude any non-stringable placeholders, as the PSR-3 logging standard states that "the array can contain anything. Implementors MUST ensure they treat context data with as much lenience as possible. A given value in the context MUST NOT throw an exception nor raise any php error, warning or notice."
Proposed in #21 raise an exception when trying to write a log with placeholders that cannot converted into strings. Also, if possible, try to indicate where this error was produced as part of the raised exception. #52
