This commit performs a second pass over the `std::string` module, performing the following actions: * The name `std::string` is now stable. * The `String::from_utf8` function is now stable after having been altered to return a new `FromUtf8Error` structure. The `FromUtf8Error` structure is now stable as well as its `into_bytes` and `utf8_error` methods. * The `String::from_utf8_lossy` function is now stable. * The `String::from_chars` method is now deprecated in favor of `.collect()` * The `String::from_raw_parts` method is now stable * The `String::from_str` function remains experimental * The `String::from_raw_buf` function remains experimental * The `String::from_raw_buf_len` function remains experimental * The `String::from_utf8_unchecked` function is now stable * The `String::from_char` function is now deprecated in favor of `repeat(c).take(n).collect()` * The `String::grow` function is now deprecated in favor of `.extend(repeat(c).take(n)` * The `String::capacity` method is now stable * The `String::reserve` method is now stable * The `String::reserve_exact` method is now stable * The `String::shrink_to_fit` method is now stable * The `String::pop` method is now stable * The `String::as_mut_vec` method is now stable * The `String::is_empty` method is now stable * The `IntoString` trait is now deprecated (there are no implementors) * The `String::truncate` method is now stable * The `String::insert` method is now stable * The `String::remove` method is now stable * The `String::push` method is now stable * The `String::push_str` method is now stable * The `String::from_utf16` function is now stable after its error type has now become an opaque structure to carry more semantic information in the future. A number of these changes are breaking changes, but the migrations should be fairly straightforward on a case-by-case basis (outlined above where possible). [breaking-change]

// The MAX_PATH is 260, but 253 is the practical limit due to some API bugs
|
|
// See http://msdn.microsoft.com/en-us/library/windows/desktop/aa365247.aspx for good information
|
|
// about windows paths.
|
|
// That same page puts a bunch of restrictions on allowed characters in a path.
|
|
// `\foo.txt` means "relative to current drive", but will not be considered to be absolute here
|
|
// as `∃P | P.join("\foo.txt") != "\foo.txt"`.
|
|
// `C:` is interesting, that means "the current directory on drive C".
|
|
// Long absolute paths need to have \\?\ prefix (or, for UNC, \\?\UNC\). I think that can be
|
|
// ignored for now, though, and only added in a hypothetical .to_pwstr() function.
|
|
// However, if a path is parsed that has \\?\, this needs to be preserved as it disables the
|
|
// processing of "." and ".." components and / as a separator.
|
|
// Experimentally, \\?\foo is not the same thing as \foo.
|
|
// Also, \\foo is not valid either (certainly not equivalent to \foo).
|
|
// Similarly, C:\\Users is not equivalent to C:\Users, although C:\Users\\foo is equivalent
|
|
// to C:\Users\foo. In fact the command prompt treats C:\\foo\bar as UNC path. But it might be
|
|
// best to just ignore that and normalize it to C:\foo\bar.
|
|
//
|
|
// Based on all this, I think the right approach is to do the following:
|
|
// * Require valid utf-8 paths. Windows API may use WCHARs, but we don't, and utf-8 is convertible
|
|
// to UTF-16 anyway (though does Windows use UTF-16 or UCS-2? Not sure).
|
|
// * Parse the prefixes \\?\UNC\, \\?\, and \\.\ explicitly.
|
|
// * If \\?\UNC\, treat following two path components as server\share. Don't error for missing
|
|
// server\share.
|
|
// * If \\?\, parse disk from following component, if present. Don't error for missing disk.
|
|
// * If \\.\, treat rest of path as just regular components. I don't know how . and .. are handled
|
|
// here, they probably aren't, but I'm not going to worry about that.
|
|
// * Else if starts with \\, treat following two components as server\share. Don't error for missing
|
|
// server\share.
|
|
// * Otherwise, attempt to parse drive from start of path.
|
|
//
|
|
// The only error condition imposed here is valid utf-8. All other invalid paths are simply
|
|
// preserved by the data structure; let the Windows API error out on them.
