2020-01-16malloc: remove lockingDan Cross2-31/+3
The issue manifests in fork: POSIX fork mandates that a fork'd process is created with a single thread. If a multithreaded program forks, and some thread was in malloc() when the fork() happened, then in the child the lock will be held but there will be no thread to release it. We assume the system malloc() must already know how to deal with this and is thread-safe, but it won't know about our custom spinlock. Judging that this is no longer necessary (the lock code was added 15 years ago) we remove it. Signed-off-by: Dan Cross <cross@gajendra.net>
2020-01-16lib9: putenv wraps POSIX setenv, not legacy putenvDan Cross1-7/+1
POSIX setenv does everything that p9putenv's body, so just delegate to that. Signed-off-by: Dan Cross <cross@gajendra.net>
2020-01-14lib9: make formatting lock-free againRuss Cox4-124/+83
First use of <stdatomic.h>. We will see if any supported systems don't have it yet. (C11 was so last decade.) Fixes #338.
2020-01-13lib9: do not fetch disk size for character devicesRuss Cox1-1/+1
Real disk devices should be block devices anyway. One user reported the disksize check causing a system reboot during vac of a tree with an "interesting" device. Fixes #103.

2020-01-12lib9: make a p9frexp function wrapping system frexpRuss Cox2-0/+10
Under certain conditions it looks like frexp gets #defined to something else on macOS during system headers, which then breaks the declaration in libc.h.

As usual, gcc finds some real problems but also reports a ton of noise. Fix the problems and quiet the noise.

2020-01-07lib9, libndb: exclude terminating null from strncpy boundNeven Sajko1-1/+1
GCC pointed this out with some "warning: ‘strncpy’ specified bound NUM equals destination size [-Wstringop-truncation]" warnings. Change-Id: Id8408b165f6e4ae82c96a77599d89f658d979b32
2020-01-07lib9: remove getcallerpc implementationsRuss Cox8-55/+1
These make no sense and are not really needed at all. Add a best-effort attempt to get at the gcc/clang macro in lib9.h, but if it fails, no big deal. Fixes #324.

2017-06-19lib9: fix needsrcquoteRuss Cox1-1/+1
As written, it is passing a rune to strchr, which likely ignores all but the bottom 8 bits of the rune. Long-standing Plan 9 bug too. Fixes #87. Change-Id: I6a833373b308bed8760d6989972c7f77b4ef3838 Reviewed-on: https://plan9port-review.googlesource.com/2921 Reviewed-by: Russ Cox <rsc@swtch.com>

2012-06-02lib9/dial: add support for IPv6David du Colombier3-100/+86
The function p9dialparse() returns the host as a sockaddr_storage structure instead of a u32int, to be able to handle both IPv4 and IPv6 addresses. Because the sockaddr_storage structure also handle port numbers and Unix path names, there is no longer need to set them in the calling functions. However, these values are still returned for convenience. The sockaddr_in and sockaddr_un structures have been replaced by sockaddr_storage to handle Unix, IPv4 and IPv6 sockets. Names and addresses are resolved using either gethostbyname() or getaddrinfo() functions. The getaddrinfo() function is documented in RFC2553 and standardized since POSIX.1-2001. It supports both IPv4 and IPv6 addresses. The gethostbyname() function is deprecated since POSIX.1-2008. However, some libc implementations don't handle getaddrinfo() properly, thus we preferred to try gethostbyname() first. I've tried to preserve most of the old code logic to prevent from surprising or unwanted behavior. R=rsc http://codereview.appspot.com/6255068
