- destroying a non-default loop would stop the global waitpid
watcher (Denis Bilenko).
- queueing pending watchers of higher priority from a watcher now invokes
......@@ -32,6 +36,8 @@ TODO: document file descriptor usage per loop
- (ecb) add memory fence support for gcc-alpha (Christian Weisgerber).
- work around some kernels losing file descriptors by leaking
the kqueue descriptor in the child.
- work around linux inotify not reporting IN_ATTRIB changes for directories
in many cases.
- include sys/syscall.h instead of plain syscall.h.
- check for io watcher loops in ev_verify, check for the most
common reported usage bug in ev_io_start.
......@@ -46,6 +52,13 @@ TODO: document file descriptor usage per loop
- rewrite the async/signal pipe logic to always keep a valid fd, which
simplifies (and hopefuly correctifies :) the race checking
on fork, at the cost of one extra fd.
- add fat, msdos, jffs2, ramfs, ntfs and btrfs to the list of
inotify-supporting filesystems.
- move orig_CFLAGS assignment to after AC_INIT, as newer autoconf
versions ignore it before
(https://bugzilla.redhat.com/show_bug.cgi?id=908096).
- add some untested android support.
- enum expressions must be of type int (reported by Juan Pablo L).
