1. 3 problems using CGI in Euphoria
Hi everyone. I encountered a few problems when using CGI. Can someone kindly
help?
Environment: Windows Server 2003, IIS6
1. exwc.exe keeps running after submiting a form until CGI Timeout. But when
compiled to exe it works as expected.
2. I found the postdata() in LibCGI v1.5 doesn't work correctly, to be specific
the "HEREHEREHEREHERE" part.
global function post_data()
object in
sequence buf buf = {}
while 1 do
in = gets(0) --HEREHEREHEREHERE
if equal(in, -1) then
return buf
else
if in[length(in)] = '\n' then -- strip \n
in = in[1..length(in)-1]
end if
buf &= in
end if
end while
end function
And I change it according to the CGI Support Routines by Aku
global function post_data()
object lenq
lenq = getenv("CONTENT_LENGTH")
if atom(lenq) or length(lenq) < 1 then
return ""
else
return get_bytes(0, val(lenq))
end if
end function
And it works. So why get_bytes() not gets()?
3. I can't read data from a form enctype="multipart/form-data", neither
get_bytes() nor gets(). The LibCGI v1.5 routine doesn't work, and Aku's library
contains no routine for that.
Thanks in advance.

Try:
without warning
I recall that in CGI apps exwc might not terminate if it
outputs warnings. It tries to say "Press Enter" and waits
for the user to press Enter (which never happens).

I'm not sure if this affects you or not, but
on Windows, file input from standard input (file 0)
is always in text mode (\r\n is converted to \n), so there will be
problems if you need binary input. Things work fine
on Linux/FreeBSD. There may be a way to deal with this, but
no one ever got around to doing it (e.g. adding some command
to switch Windows standard input to binary).

This is where having a non executing (syntax testing only)
version of Euphoria helps. I have several production scripts where
I need to make a tweak from time to time,
but cannot effectively test it inside the production environment.
I modified the ex.exw in a prior version, bound an executable from it
and added the resulting syncheck executable to my "send to" menu
so syntax testing is only a right click away.
For the above problem,
If it still hangs after turning off warnings then
you need to search for an ex.err file, it will not neccesarily be in the
same directory as your script,because of the executing environment.
Alternately supply a hard coded crash file path.
