I am hesitant to apply it because IMO it is not well optimized. It uses TFileStream, then a char buffer and then the Result string. Data is moved between them 3 times, isn't it? Another reason for hesitation: we don't have any acute bug concerning function ReadFileToString() that needs fixing. Yes I know the current function does not work with virtual files in Unix systems. Fixing that is a good idea but the new function should be as fast or faster than the current one which calls FileSize(). What is the overhead caused by FileSize()? I don't know but the speed of potential ReadFileToString() replacements should be compared. Did you compare them? If somebody comes up with a good optimised version, I promise to apply it. One problem is also that you often concentrate on trivial unimportant details of Lazarus sources instead of fixing real bugs. I know real bugs require diving deep into the code, hours of studying and debugging. It is harder than the trivial changes but there is no alternative when fixing the really nasty bugs.
