COW or Copy On Write introduction\n\nA COWed SvPV is sharing its string (the PV) with other SvPVs. It's a\n(kind of) Read Only C string, that would be Copied On Write (COW).\n\nMore than one SV can share the same PV, but when one PV need to alter\nit, it would perform a copy of it, decrease the COWREFCNT counter.\n\nOne SV can then drop the COW flag when it's the only one holding a\npointer to the PV.\n\nThe COWREFCNT is stored at the end of the PV, after the the \"\\0\".\n\nThat value is limited to 255, when we reach 255, a new PV would be\ncreated,","flavors":[],"html":"https://daemonports.org/netbsd/devel/p5-B-COW/","kind":"port","lastUpdate":"2026-07-16T19:01:23Z","license":["gnu-gpl-v2 OR artistic"],"maintainer":"pkgsrc-users@NetBSD.org","name":"p5-B-COW","newest":true,"newestVersion":"0.007","noVulnData":false,"origin":"devel/p5-B-COW","otherSystems":[{"maintainer":"sunpoet@FreeBSD.org","newest":true,"origin":"devel/p5-B-COW","path":"/devel/p5-B-COW/","system":"FreeBSD","version":"0.007"},{"maintainer":"Alexander Bluhm \u003cbluhm@openbsd.org\u003e","newest":true,"noVulnData":true,"origin":"devel/p5-B-COW","path":"/openbsd/devel/p5-B-COW/","system":"OpenBSD","version":"0.007"},{"maintainer":"sunpoet@FreeBSD.org","newest":true,"origin":"devel/p5-B-COW","path":"/dragonfly/devel/p5-B-COW/","system":"DragonFly","version":"0.007"},{"maintainer":"ports@MidnightBSD\u003eorg","newest":true,"noVulnData":true,"origin":"devel/p5-B-COW","path":"/midnightbsd/devel/p5-B-COW/","system":"MidnightBSD","version":"0.007"},{"maintainer":"sunpoet@FreeBSD.org","newest":true,"noVulnData":true,"origin":"devel/p5-B-COW","path":"","system":"HardenedBSD","version":"0.007"},{"maintainer":"sunpoet@FreeBSD.org","newest":true,"noVulnData":true,"origin":"devel/p5-B-COW","path":"","system":"GhostBSD","version":"0.007"}],"packages":[{"repo":"NetBSD 10.1 x86_64","versions":["0.007nb3"]},{"repo":"NetBSD 10.1 aarch64","versions":["0.007nb3"]},{"repo":"SmartOS / illumos x86_64","versions":["0.007nb3"]},{"repo":"macOS 15 arm64","versions":["0.007nb3"]}],"pkgName":"p5-B-COW-0.007nb3","related":null,"repository":"pkgsrc","requiredBy":["databases/p5-CDB_File"],"requiredByCount":1,"runDepends":["lang/perl5"],"status":null,"system":"netbsd","systemLabel":"NetBSD","version":"0.007nb3","versions":null,"vulnerabilities":null,"www":"https://metacpan.org/pod/B::COW"}
