It looks like 0040000 (octal) is the flag for directories on
linux, but it does seem that std.zip is explicitly returning 0 if
the file was created on the opposite platform re: Posix vs
Windows, which is... odd.
@property @nogc nothrow uint fileAttributes() const
{
version (Posix)
{
if ((_madeVersion & 0xFF00) == 0x0300)
return _externalAttributes >> 16;
return 0;
}
else version (Windows)
{
if ((_madeVersion & 0xFF00) == 0x0000)
return _externalAttributes;
return 0;
}
else
{
static assert(0, "Unimplemented platform");
}
}
Looks like the only way around it is modifying std.zip? Adding
something like:
@property bool isDir() const {
enum uint FILE_ATTRIBUTE_DIRECTORY = 0x10; // WINNT.h
enum uint S_IFDIR = 0x4000; // sys/stat.h
version(Windows) {
if ((_madeVersion & 0xFF00) == 0x0300) // Archive made on Posix
return cast(bool) (_externalAttributes & (S_IFDIR <<
16));
return cast(bool) (_externalAttributes &
FILE_ATTRIBUTE_DIRECTORY);
} else version(Posix) {
if ((_madeVersion & 0xFF00) == 0x0300) // Archive made on Posix
return cast(bool) (_externalAttributes & (S_IFDIR <<
16));
return cast(bool) ((_externalAttributes) &
FILE_ATTRIBUTE_DIRECTORY);
} else {
static assert(0, "Unimplemented platform");
}
}
will let me do this:
void main() {
foreach (zipfile; ["windowstest.zip", "linuxtest.zip"]) {
writeln(zipfile);
auto zip = new ZipArchive(std.file.read(zipfile));
foreach (fn, am; zip.directory) {
writefln("%24s %5s %s", fn, am.isDir,
am.fileAttributes);
}
}
}
Results on Windows:
windowstest.zip
a.txt false 32
testdir/ true 16
testdir/b.txt false 32
linuxtest.zip
a.txt false 0
testdir/ true 0
testdir/b.txt false 0
Results on Linux:
windowstest.zip
testdir/ true 0
testdir/b.txt false 0
a.txt false 0
linuxtest.zip
testdir/ true 16893
testdir/b.txt false 33204
a.txt false 33204
