Hi, I'm trying to learn how the last version of Go that is bootstrapped from C works and as a learning exercise, maybe try porting to a new OS (on x86 for now)...
So I'm trying to get my head around the xrealdwd() function in /src/cmd/dist/unix.c - I just can't grok why it is needed. A quick search indicates that xrealdwd() is only ever used by build.c, and the comment in build.c says: // xgetwd might return a path with symlinks fully resolved, and if // there happens to be symlinks in goroot, then the hasprefix test // will never succeed. Instead, we use xrealwd to get a canonical // goroot/src before the comparison to avoid this problem. I guess my understanding and knowledge of symlinks is lacking, but I guess i just don't understand why hasprefix() will never succeed if there happens to be symlinks in goroot... The windows.c file also has a similar (at least similar in logic but not in OS calls) approach to xrealdwd() so I must assume that hasprefix() does not like symlinks on Windows either? I think if this were ported to an OS that doesnt have symlinks, I might be able to get away with making xrealwd() always just return the current directory without trying to get a canonical path to goroot/src...
