plan9port/src/lib9, branch patch Plan 9 from User Space (with patches) all: remove need for `-fcommon` 2025-07-25T16:25:11+00:00 Dan Cross cross@gajendra.net 2025-07-23T10:47:21+00:00 156e745be9f6a1b19b0f8e2a931148786d7acad4 Use `extern` where appropriate so that we can remove `-fcommon` on macOS and others. On macOS, `-fcommon` generates a number of linker warnings. I've tested building on macOS, Linux, FreeBSD, NetBSD, OpenBSD and illumos. I am not in a position to test on AIX or other more esoteric platforms, however.

all: update for new MIT license 2021-03-24T00:59:23+00:00 Russ Cox rsc@swtch.com 2021-03-23T21:24:35+00:00 88a87fadae6629932d9c160f53ad5d79775f8f94 On March 23, 2021, Nokia transferred the copyrights in the Plan 9 software to the Plan 9 Foundation, which relicensed them under the MIT license. This commit updates the Plan 9 from User Space license to reflect the new base license. The vast majority of the contributions beyond the base Plan 9 set were by me, many of them explicitly under an MIT license. Those are all under the new MIT license now as well. The port of mk to Unix was taken from Inferno via Vita Nuova and had been made available under GPL, but Vita Nuova has relicensed Inferno under the MIT license as well, to match the new Plan 9 license.

getdirentries(2) has been deprecated on macOS since 10.5 (ten releases ago).
Using it requires disabling 64-bit inodes, but that in turn makes binaries
incompatible with some dynamic libraries, most notably ASAN.

At some point getdirentries(2) will actually be removed.

For both these reasons, switch to opendir/readdir.
A little clunky since we have to keep the DIR* hidden away
to preserve the int fd interfaces, but it lets us remove a bunch
of OS-specific code too.
