Anyone following the dialog on [EMAIL PROTECTED] and [EMAIL PROTECTED] is
already
aware of problems users are hitting with httpd 2.2.7 and modperl.
Here's my current theory in search of a sanity check.
There are two general classes of 'major issues' that we are going to
encounter with msvc interop between httpd, perl and modperl.
* malloc'ator flaws; memory allocated in one components heap and
later freed in another
* stdio/posix io handles. These don't map between one and another.
To solve the first issue, there is only one solution. Because perl
and modperl are both managing perl memory allocate/free, those must
be compiled against the same msvc lib. That means using perl's
compile hinting. In practice, this may be the difference between
a user who says "yup, works for me" and those who fail utterly.
Likewise they should use an openssl etc which are compiled against
perl's choice, or that blows up for certain openssl-oriented xs's
which have the same tight integration.
To solve the second issue, I think we can hack it.
What if modperl verified, and reinitialized if necessary, the stdio
handles associated with "its msvcrt" during the register_hooks phase
and again during the open_logs hook (run as 'very last'). This should
ensure the stdio handles are legit even if httpd started under one
msvcr, while perl and modperl are running under another.
Just a thought, I have a bunch on my plate but I wanted to float a
possible solution.
