Description Mario Duhanic 2021-02-22 15:45:46 UTC
Created attachment 222726 [details]
diff -u files/patch-Makefile

changed dynamic-space-size from 4 GiB to 1 GiB for all non-64 versions, poudriere testport ran without problems on both amd64 and i386, s.a. bug #252716

affects: files/patch-Makefile

PORTREVISION: not raised, as this port version never was built (on i386), s. Porter's Handbook 4.3.1

This seems to be working in gerneral.
But instead of trying to pattern-match on the machine architecture name, wouldn't it be more correct (and perhaps more robust - e.g. when new architecture names are invented) to use getconf to test for pointer size? I think "POSIX_V6_LPBIG_OFFBIG" ("at least 64 bit pointer") would be the thing to test for?
Comment 3 Christoph Moench-Tegeder freebsd_committer 2021-02-23 19:26:48 UTC
(In reply to Christoph Moench-Tegeder from comment #2)
ah, we only have POSIX_V6_LP64_OFF64, not the "BIG" variant

Thanks for the comments!

I was thinking about truncating "sysctl -n hw.usermem" somehow (to avoid an overflow) and checking if we are able to allocate 1 or 4 GiB or so to come back to the initial problem "can I haz memory". But this didn't seem to look quite elegant.

Now I'm using "getconf LONG_BIT" to compare against, which should cover hopefully all or most of the ILP32 and LP64 data model cases, see also the sys/*/include/_limits.h.

Poudriere ran on both amd64 and i386 without problems with the desired and expected results.

Author: cmt
Date: Wed Feb 24 21:43:00 UTC 2021
New revision: 566509
URL: https://svnweb.freebsd.org/changeset/ports/566509

  allow pgloader3 to build on 32bit platforms

  guess if we're on a 32bit platform and set a reduced DYNSIZE - else
  sbcl may hit it's adress space limits.

Comment 6 Christoph Moench-Tegeder freebsd_committer 2021-02-24 21:46:48 UTC
ok, let's try this. I'm not sure if this is the best approach - after all, we're probably not that interested in the size of a long but in the pointer size, but testing for that might even messier.
Anyways, committed ports r566509
