suggestions, bugs and core dumps with 2.0b7
I thought I'd email with a list of issues I have encountered with 2.0b7. Some of this took ages to work out and I'd hate to think anyone else would have to repeat the exercise. I look forward to a 2.0b8.
1. embpcgi.pl will core dump on 2.0b7 if you run it without setting up any environment variables because it doesn't know what file it wants to run. I can't remember the code path but basically it checks for a specific filename passed to Execute, then it checks the environment variables, and eventually it dereferences a pointer that's NULL.
2. embperl core dumping on solaris due to the lprint NULL (http://www.ecos.de/~mailarc/embperl/2002-04/msg00139.html) is very very annoying, it took ages to realise this affected more than make test, mainly due to the core dump occuring when you run embpcgi.pl without any environment variables, so I thought this didn't make any difference when it most certainly does.
3. the "Content-Length: 2" bug is present in 2.0b7 which was mentioned way back in January on the mailing list, but rather than just get < in the HTML, Internet Explorer 5.5 shows the first block of data, so my pages failed after 5k of data. You won't believe how long it took me to work this one out. It seems MSIE only checks the Content-Length *after* it has processed the first block of data, so the truncation can happen anywhere in the page, but usually on a 5k or so boundary. wget, mozilla, etc. all displayed "<".
4. it would be nice if local variables for [$ sub $] using [* my ... *] were documented, I only found a reference to doing that on the mailing list and it was my first question when I started using sub.
I'm sure you know about these already, but here are the patches I am using:

Inputfile) ;
#ifdef CLOCKS_PER_SEC
lprintf (r -> pApp, "[%d]PERF: Time: %d ms ", r -> pThread -> nPid, (
(cl - r -> startclock) * 1000 / CLOCKS_PER_SEC)) ;
#else

lprintf (r -> pApp, "[%d]PERF: Time: %d ms ", r -> pThread -> nPid, (

nent.pCurrEscape?2:0)) ;
! oputs (r, txt) ;
if (pCookie)
{
oputs (r, "Set-Cookie") ;
--- 967,974 ----

mponent.pCurrEscape?2:0)) ;

Hi,
> I thought I'd email with a list of issues I have encountered with 2.0b7.
Some of this took ages to work out and I'd hate to think anyone else would
have to repeat the exercise. I look forward to a 2.0b8.

Thanks for your fixes. The first three bugs you mention are already fixed in
my developemnet version. I hope I can release 2.0b8 during the next days.

The [* my *] didn't work in 1.3.x, so it's new in 2.0 and unfortunately
there are many more things that are undocumented in 2.0. I currently working
on the docs, because the docs are the main reason, why I can't make a final
release of 2.0, but it's really a lot of stuff, so it may take a while to
get it written down.
Anyway thanks for sharing this
Gerald
