In the 1.4 release notes, I have read that:
=> new free fixup functions - making safer to use some functions
exported by modules in embedded languages such as Perl
I don't find any reference to "free_fixup_function" in the Perl module
source code.
Are you sure that this feature works for Perl module?
Someone work on it?
Best Regards,

Makes me wonder what is inherently "unsafe" about it as well.

Well, in my case one of Perl's packages has a memory leak (DBD::Sybase).
What I *could* assume is the 'fixup' function clears out any residual
memory, but perhaps this is just wishful thinking on my behalf.
As for fixing the Perl package in question, don't ask...

Nothing is unsafe.
If you try to call a function exported by another module with Perl, Perl
module refuses.
The "free_fixup_function" mechanism is not implemented in the Perl module.
But, this sentence suggests the contrary:
=> new free fixup functions - making safer to use some functions exported
by modules in embedded languages such as Perl
For the same reason, the Perl module documentation is not up to date.
In the documentation, you can read this kind of example :
$m->moduleFunction("sl_send_reply",
"500", "Internal Error");
$m->moduleFunction("xlog", "L_INFO", "foo");
But with the 1.4 release, it doesn't work.

reading now seems to suggest
that, what I meant that the support for
freeing fixup is there, basically some functions exported by modules can
be used dynamically from other modules. In the past, functions exported
to config couldn't be just imported unless the parameters after fixup
were known, exposing to issues while updating fixup function and fixup
parameter structure.
While this is not advisable as the module can actually export a C api,
the feature will help when the functions will be used in embedded
programs like perl or for a better clean up at shutdown.
Cheers,
Daniel

Do you known if somebody works on the integration of this feature in the
Perl module ?
If it's not the case, I am potentially interest to do that.

That would be great

the only issue now is for the functions that don't have a free fixup
function
- either is no need for it
- or not implemented it
I believe the solution is to add kind of free_fixup_nop() function that
does nothing so the first case can be safely detected and made available
for usage.
Please commit the code when you have the time, so I can continue the
work with free fixups. Not all modules will be enabled, depends on the
developers at some point as I am not using all of them, but the basic
ones are already/going to have all in place.
Thank you,
Daniel
