Useful to know when the the event loop is empty, this can't be done with
uv_run() without possibly blocking, or running some events (which might
empty the event loop as a side-effect).
gyp currently doesn't support the --generator-output option for android,
this is the best way to ignore generated files for projects using libuv
as a dependency.
Allow UV_EACCES as a successful return value when uv_spawn fails.
When the PATH environment variable contains a directory which the
user cannot access, execvp may return EACCES instead of ENOENT.
fix#1045.
`uv_try_write(stream, buf, size)` acts like `uv_write()`,
but without queueing actual write until UV_POLLOUT (or IOCP completion).
This is useful for doing writes using on-stack `uv_write_t` requests.
fix#1025
We weren't always translating system errors for in uv_spawn.
This is half a fix for node's unit test
test-child-process-cwd.js on win.
The rest will go into node lib.
It also fixes test-child-process-exec-error
When using configure, there are situations where libuv will attempt
to build uv-dtrace.h, even if it is configured with --disable-dtrace.
For example, if libuv is first configured with dtrace enabled, then
built, the .deps files will contain references to include/uv-dtrace.h.
After a make clean and configure --disable-dtrace, the build will still
attempt to create include/uv-dtrace.h and fail. make will see the
dependency reference (which survives the make clean), use the rule
(which is always added to the Makefile), and fail since DTRACE is not
defined.
This commit protects the rules to make uv-dtrace.h with the proper
conditionals to ensure the rules are not written if --disable-dtrace
is chosen.
Fix#963.
Large performance counter frequency values would cause overflows, even
when 64-bit integers were used to do the multiplication with NANOSEC.
Fix this by using floating point math instead.
Fixes#850
First of all, a bit of explanation of what happens there:
1. FSEvents emits absolute paths to changed files or directories
2. We cut off the first part of such paths, which is equal to handle's
real path ('/dir/subdir/subsubdir`, without trailing slash)
3. Then, if we are running in non-recursive mode, we discard paths that
have slashes ('/') as a non-first character in them
Commit 3d2c820 back-ports a patch from the master branch that disables
the use of SO_REUSEPORT on Linux for reasons mentioned in the commit
log.
Unfortunately, the back-port was incomplete; another setsockopt() call
site in src/unix/udp.c was overlooked. This commit rectifies that.
Hat tip to Luca Bruno for helping troubleshoot the issue.
Fix a bug that was introduced in commit 3ee4d3f ("unix, windows:
return error codes directly") and add a regression test for good
measure.
Hat tip to Fedor for pointing out the issue.
Fixes#1007.
Print the error message rather than just the errno. The fact that the
errno is 24 is only informative to people that have their operating
system's error codes memorized.
Set the close-on-exec flag on file descriptors that we've received with
recvmsg() so we don't leak them when calling fork() afterwards.
On Linux, we use the MSG_CMSG_CLOEXEC flag when supported (2.6.23 and
up.)
On older Linux versions and other platforms, we walk the received file
descriptors and set the close-on-exec flag for each fd manually. That
won't entirely avoid race conditions when other threads call fork() or
clone() but at least we're less likely to leak file descriptors now.
