Derek Foreman	5c48aac33b	cursor: Remove "weston" from anonymous shm filenames ... This mildly confused me during some debugging, so I guess it wouldn't hurt to make the filename more indicative of where it was actually created.

Pekka Paalanen	011b695403	os: use posix_fallocate in creating sharable buffers ... If posix_fallocate is available, use it instead of ftruncate. Unlike ftruncate, when posix_fallocate succeeds, it guarantees that you cannot run out of disk space, when later writing to the mmap()'ed file. With posix_fallocate, if os_create_anonymous_file() succeeds, the program cannot get a SIGBUS later from accessing this file via mmap. If there is insufficient disk space, the function fails and errno is set to ENOSPC. This is useful on systems, that limit the available buffer space by having XDG_RUNTIME_DIR on a small tmpfs.

Pekka Paalanen	a88a4386cb	cursor: use os_create_anonymous_file() ... Copy the implementation of os_create_anonymous_file() here from weston, so we can use it instead of hardcoding a path to /tmp. Signed-off-by: Pekka Paalanen <ppaalanen@gmail.com>	2012-07-10 14:08:59 -04:00
