src,worker: display remaining handles if `uv_loop_close` fails #21238

addaleax · 2018-06-09T22:46:35Z

This is refactoring our native stack trace code, and adding support for a better error message when a uv_loop_close() for a worker fails because there are still active handles.

Example output in that case (taken from test failures on the current canary branch while looking into nodejs/node-v8#66):

uv loop at [0x5623f5b32950] has active handles
[0x5623f5b13360] async
	Close callback: (nil) 
	Data: 0x5623f5b343e0 
	(First field): 0x5623f4dbf000 vtable for node::PerIsolatePlatformData [out/Release/node]
out/Release/node[28598]: ../src/debug_utils.cc:217:void node::CheckedUvLoopClose(uv_loop_t*): Assertion `0 && "uv_loop_close() while having open handles"' failed.
 1: node::Abort() [out/Release/node]
[ ... stack trace ... ]

As opposed to the previous error message:

out/Release/node[31550]: ../src/node_worker.cc:307:virtual node::worker::Worker::~Worker(): Assertion `(uv_loop_close(&loop_)) == (0)' failed.
 1: node::Abort() [out/Release/node]
[ ... stack trace ... ]

Yeah, this is still in progress … do we have any way of detecting musl libc? It would be a shame to skip that test part for all of Linux…

bnoordhuis

Apropos checking for musl libc, it's complicated...

You can check ldd node and see if there's a line about libc.so:

If not, it's probably musl, statically linked.
If yes, check if nm /path/to/libc.so prints gnu_get_libc_version. If not, it's probably musl.

It's easier to check if os.hostname() is one of the alpine buildbots, or if /etc/alpine-release exists.

That's not strictly correct (all alpine is musl but not all musl is alpine) but it's much less brittle.

Why not ... & ~(...)? Then you don't have to suppress the linter.

I’m getting a déjà vu with that review comment … 😄 I’ve switched it for now, but I really prefer &~ for masking operations

+        reinterpret_cast<uintptr_t>(address) &~ (pagesize_ - 1));
+    return msync(page_aligned, pagesize_, 0) == 0;


I'm surprised this works; passing in no flags is technically an error (they're non-zero on linux and macos.)

@bnoordhuis I guess this could be made MS_ASYNC? Reading the Linux man page, it seems like that’s how Linux interprets 0 anyway …

I’m switching and seeing how that fares in CI.

Use a single file, and a single interface, for inspecting symbols in the current process for debugging.

Right now, we crash the process if there are handles remaining on the event loop when we exit (except for the main thread). This does not provide a lot of information about causes, though; in particular, we don’t show which handles are pending and who own them. This patch adds debug output to these cases to help with the situation.

I’ve tried the ldd + nm suggestion – let’s see how that goes, if not, we can just go for one of the simpler options.
