Author: sunpoet Date: Sun Feb 2 10:54:20 2020 New Revision: 524839 URL: https://svnweb.freebsd.org/changeset/ports/524839 Log: Add p5-B-COW 0.002 B::COW provides some naive additional B helpers to check the COW status of one SvPV. A COWed SvPV is sharing its string (the PV) with other SvPVs. It's a (kind of) Read Only C string, that would be Copied On Write (COW). More than one SV can share the same PV, but when one PV need to alter it, it would perform a copy of it, decrease the COWREFCNT counter. One SV can then drop the COW flag when it's the only one holding a pointer to the PV. The COWREFCNT is stored at the end of the PV, after the the "\0". That value is limited to 255, when we reach 255, a new PV would be created, WWW: https://metacpan.org/release/B-COW Added: head/devel/p5-B-COW/ head/devel/p5-B-COW/Makefile (contents, props changed) head/devel/p5-B-COW/distinfo (contents, props changed) head/devel/p5-B-COW/pkg-descr (contents, props changed) head/devel/p5-B-COW/pkg-plist (contents, props changed) Modified: head/devel/Makefile Modified: head/devel/Makefile ============================================================================== --- head/devel/Makefile Sun Feb 2 10:46:40 2020 (r524838) +++ head/devel/Makefile Sun Feb 2 10:54:20 2020 (r524839) @@ -1747,6 +1747,7 @@ SUBDIR += p5-AutoLoader SUBDIR += p5-AutoXS-Header SUBDIR += p5-B-C + SUBDIR += p5-B-COW SUBDIR += p5-B-Compiling SUBDIR += p5-B-Deobfuscate SUBDIR += p5-B-Flags Added: head/devel/p5-B-COW/Makefile ============================================================================== --- /dev/null 00:00:00 1970 (empty, because file is newly added) +++ head/devel/p5-B-COW/Makefile Sun Feb 2 10:54:20 2020 (r524839) @@ -0,0 +1,23 @@ +# Created by: Po-Chuan Hsieh <sunpoet@FreeBSD.org> +# $FreeBSD$ + +PORTNAME= B-COW +PORTVERSION= 0.002 +CATEGORIES= devel perl5 +MASTER_SITES= CPAN +PKGNAMEPREFIX= p5- + +MAINTAINER= sunpoet@FreeBSD.org +COMMENT= Additional B helpers to check COW status + +LICENSE= ART10 GPLv1+ +LICENSE_COMB= dual +LICENSE_FILE= ${WRKSRC}/LICENSE + +USES= perl5 +USE_PERL5= configure + +post-install: + ${STRIP_CMD} ${STAGEDIR}${PREFIX}/${SITE_ARCH_REL}/auto/B/COW/COW.so + +.include <bsd.port.mk> Added: head/devel/p5-B-COW/distinfo ============================================================================== --- /dev/null 00:00:00 1970 (empty, because file is newly added) +++ head/devel/p5-B-COW/distinfo Sun Feb 2 10:54:20 2020 (r524839) @@ -0,0 +1,3 @@ +TIMESTAMP = 1580562231 +SHA256 (B-COW-0.002.tar.gz) = fce7738147ef00bd342575d942d469d4a0002740ed6cdd73f121ef12bae8577c +SIZE (B-COW-0.002.tar.gz) = 18194 Added: head/devel/p5-B-COW/pkg-descr ============================================================================== --- /dev/null 00:00:00 1970 (empty, because file is newly added) +++ head/devel/p5-B-COW/pkg-descr Sun Feb 2 10:54:20 2020 (r524839) @@ -0,0 +1,12 @@ +B::COW provides some naive additional B helpers to check the COW status of one +SvPV. + +A COWed SvPV is sharing its string (the PV) with other SvPVs.
