dillo3.0.2 Irix

[Jan Diegelmann]

Hello,

I try to port dillo 3.0.2 to Irix:

fltk 1.3 compiles fine with gcc 4.7. test/demo runs without errors.

dillo compiles also with gcc 4.7, there is only a problem with setenv in
dpi/downloads.cc, that can be resolved using putenv.

I also tried with --disable-threaded-dns but same result.

Any idea how to debug this problem?

Thank you,

Jan

Do the dw* programs in dillo's test directory do anything?

Given that you aren't getting any repush messages, I'm guessing that
they'll be reasonably okay and that it's something to do with IO.

I'm not the expert on that code, but in the interest of giving something
to try in the meantime, I might start by setting breakpoints on
IO_fd_write_cb() and IO_fd_read_cb(), or setting VERBOSE in src/chain.c.

Thanks for your hints. The browser is able to render html. about:splash
looks normal and sometimes you can open html files with the open file
menu, sometimes you get a 404 error when you try to open a html file,
this behavior seems to be random. I set VERBOSE. This is the output when
I start dillo, try to surf home (don't work) and open a JPEG in the /tmp
directory (works).

The tests provide some output. The cookies test for esample outputs endless:

Hmm... I wonder whether this would show anything interesting
(run 'dpidc stop' before reinstalling DPIs)

Nothing new with this patch. I found out it is not random, it
file:/tmp/12345678901234567890123.jpg
but
file:/tmp/123456789012345678901234.jpg
returns a 404

32-byte limit?

The first thing that popped into my mind was that sufficiently ancient
systems would have path length limits like 32, but I don't see why that
would apply here...

dpi/file.c's File_normalize_path() has a "Dstr *ds = dStr_sized_new(32)".
You could change the number and see whether anything happens. Although if
Dstr should have problems resizing itself on irix, I'd be very surprised
that dillo could even run at all.
