Hi, I run the Austin Swift meetup group, and a question came up about the /proc filesystem on Linux: The question involved the inability to get any useful information from Data (contentsOf: URL(fileURLWithPath: "/proc/sys/fs/file-max")). It turns out that Data(contentsOf:) does a stat() on the inode of the file you give it, and then runs alloc()/read() for the specified number of bytes. This works fine on normal files on normal file systems. But all the files in /proc have a 0 length specified by their inodes, and you have to actually read them until EOF to find out how much is there. So the question is: Is that something the *Programmer* should be responsible for knowing, or should *Foundation* be responsible for handling that correctly? I can see a case that we'd want to avoid embedding things this OS-specific in Foundation, but on the other hand, I know that this is very confusing for Darwin developers moving to Linux and expecting Data(contentsOf:) to "Just work." So I thought I'd ask the community and see if there was a consensus. Thanks, -Carl -- Carl Brown Swift@IBM carl.bro...@ibm.com
