Subject: [PATCH] Implement caller_cx
Date: Tue, 4 Mar 2014 18:14:23 +0000
To: bug-Devel-PPPort [...] rt.cpan.org
From: Ben Morrow <ben [...] morrow.me.uk>
The attached patch adds an implementation of caller_cx. I've tested it with various perls back to 5.6.0; I can't get any earlier perls to build (even with buildperl.pl: I get sed: -e: No such file or directory sed -i -e '/^.*<builtin>/d' -e '/^.*<built-in>/d' -e '/^.*<command Show quoted text
line>/d' -e '/^.*<command-line>/d' makefile x2p/makefile: 256
). Ben

Thanks! If someone else doesn't get to this before me soon, I'll take a look at it in the next two-three weeks. -- Matthew Horsfall (alh)

Are you running this on a Mac? The Mac and GNU sed utilities are sadly incompatible. You might be luckier with a GNU sed.

While I could install gsed from ports, it gets installed as 'gsed' to avoid conflicting with the system sed, so that doesn't help much. If I fix the sed invocations I get prototype conflicts in malloc.c. I can make them go away by passing -Dccflags=-DHIDEMYMALLOC to Configure, but first the 'extracting symbols from libc' step fails and Configure fails to find any of the symbols it's looking for, and then compilation fails here: util.c: In function 'vsprintf': util.c:1408: error: argument 'pat' doesn't match prototype /usr/include/stdio.h:276: error: prototype declaration util.c:1408: error: argument 'args' doesn't match prototype /usr/include/stdio.h:276: error: prototype declaration util.c:1411: error: 'FILE' has no member named '_ptr' util.c:1412: error: 'FILE' has no member named '_cnt' util.c:1416: error: 'FILE' has no member named '_flag' util.c:1416: error: '_IOWRT' undeclared (first use in this function) I also get some worrying warnings about casting pointers to int (this is a 64bit machine). Obviously this isn't going to work without a fair amount of porting effort. Ben

I've added your patch with slight modifications ( shown here: https://github.com/mhx/Devel-PPPort/commit/b4b2c6277deb9e8a3eafc5e2cb44a78b33e597d3 and here https://github.com/mhx/Devel-PPPort/commit/3fafaba96472fc14b20c4555ce95193948f6d424 ). It's only supported as far back as 5.6.0, as there are issues before that. If that's good enough, I'd say we can close this ticket. If you want the support to go further back, let's keep this open (or move it to the github tracker) so we can figure out what to do. Thanks, -- Matthew Horsfall (alh)

Looks good. Show quoted text

Yes; the cxstack was rather different before 5.6. I don't see any point going further back than that; 5.6 has not had even security fixes for many years, so anyone still using it is definitely on their own. Thank you for looking at this, Ben

Awesome. Thanks for the patch. Closing. (Released in 3.25)
