If I type `cygstart mailto:recipient?subject=subject' at a Cygwin
bash prompt, I expect my default Windows mail program to start an
outgoing message with `recipient' as recipient and `subject' as
subject. (This is what happens if I type the same URL into a
`Start Menu -> Run' box.) What happens instead is that
`recipient?subject=subject' shows up as the recipient, with the
question mark replaced by something unprintable, and the subject
is blank.

Is this a bug in cygstart, or am I misunderstanding something?
I suspect a bug in the way cygwin1.dll handles conversion from unix-
to windows-style paths.

Makes sense... for files, but we're dealing with a URL here, so it *is*
a bug IMO (but you're right, not a bug in cygwin's handling of
windows-style paths).

Cygstart knows it's dealing with a URL.

Actually, it doesn't, and that's the problem. Here's the relevant code in cygstart.c:

/* Start a program, or open a file or URL, using Cygwin POSIX paths */
static int
cygStart (const char *aPath, const wchar_t * action,
const wchar_t * args, const char *workDir,
int show, StartFlags startFlags)
/* Convert file path from POSIX to Windows, unless it looks like a URL */
if (!strstr (aPath, "://"))

Chuck, what would you think of changing this so that cygstart would
recognize `mailto:' URLs? It would also be useful if cygstart could
learn to handle `file://' URLs involving POSIX paths.

We can probably end this thread now. Yaakov has already sent a patch to cygwin-apps that does both of these things:
