Re: Is it possible to localize the stat/lstat cache?

[AnomalousMonk]

The actual calls to these other functions are uncommon in frequency ..., but there are many places in the main function that might need to call them.

If the other functions are infrequently called, what difference does it really make how many places exist in the program from which the calls might be made? To give an extreme example, if half the statements in a program are die statements, but it can be shown that all these statements are in dead code branches, what cumulative effect do these die statements have? None.

Why worry about this? Or do I simply misunderstand the problem?

The problem is that the function needs to continue after these calls to the other functions. They are exception cases (in the sense that they are rare), but they aren't branches that don't need to return and continue from there.

For example (where ... could be any set of tests, including one or more -X _ tests, and each function call could potentially need to use stat/lstat in it):

if (...) { function1(); }
if (...) { function2(); }
if (...) { function3(); }
# etc.
