Re: Proposal: removeDirectoryRecursive should not follow symlinks

I think it's safer to remove the old function altogether (perhaps after one deprecation cycle) and provide a new one under a different name, rather than modify it in place. Modifying it in place risks the behavior that others mentioned where your program is unsafe to compile against older library versions. Yes, the user could explicitly enforce that by putting a lower bound on the library, but most users won't even realize that they need to do that. On 1/6/15, 11:37 AM, Edward Kmett wrote:

I'm +1 for fixing this, in place, on the current function.

The specification we have here is doing a very very bad thing and needs to be fixed, not slavishly copied forward because someone sometime once made a mistake.

The current behavior grievously violates the expectations of anyone who would be in a situation to go and reach for it and has any prior experience with any other such tool.

I agree 100%. Even time I use this function, I worry briefly about whether it follows symlinks, then think to myself "no, no-one would be so stupid to implement that deliberately in a publically available API". So it was a real shock to discover in this thread that I was wrong, and furthermore that the function is documented as doing the wrong thing. We should fix both spec and implementation, as soon as possible.
