do i recall correctly that you're using a mac?
Yup, true.
And everything seems ok. A quick system call trace reveals that the
error is coming back from read(). I suspect there are a lot of things
that are falling back to a "mangled" message being a single text/plain
part. Can you just open directory files without any special magic on
your system? It would be interesting to see the logic flow.
yes, open(2) on linux is perfectly happy opening a directory. but
that's not the problem. (your open() is succeeding too, right?)
I guess I should have been more specific; I believe you need to pass a
special flag to open(2) so you can actually READ directories. But yes,
my read(2) is failing with EISDIR.
i'd be curious to know which read() failed for you. the first read on
the opened directory is in read_more(), at m_getfld.c:443. strace
shows me that that read() is returning EISDIR, but that the fread()
returns 0. i have no clue why it might do that, but i also see that
there's no error checking on that fread(), so i guess that's not the
one that's failing for you.
Hm, actually ... I stepped through it with a debugger, and it IS the
one who is failing.
The basic flow is:
mhshow calls parse_mime()
parse_mime() calls get_content()
get_content() decides it's a message with a single text/plain part (default)
Then the MIME display routines are called, and you end up in open7Bit().
The part where YOU fail, "internal error (3)", I go past. Because for me,
ct->c_end = 510 and ct->c_begin = 0 (which I guess is right?). I end
up failing (for the second time) at mhparse:2251 (that's the read() in
open7Bit(); line number may have changed since 1.6).
It looks like c_end is set in parse_mime(); maybe different system behavior
there between Linux and MacOS X? Not saying we don't need to fix something;
maybe the "right" fix is to properly bubble up read errors from m_getfld()?
Although ... ugh. David should weigh in what we should do there.
