We should fast track to get this in 10.x asap
Not sure why macOS CI failed, but here's a re-run: https://ci.nodejs.org/job/node-test-commit-osx/17931/ AIX re-run: https://ci.nodejs.org/job/node-test-commit-aix/14325/ |
AIX compilation failure is in new code introduced by this PR, but the libuv CI for the PR that introduced it passed on AIX, libuv/libuv#1795. ../deps/uv/src/unix/thread.c:542:28: error: size of array 'static_assert_failed' is negative
STATIC_ASSERT(sizeof(uv_sem_t) >= sizeof(uv_semaphore_t*));
^~~~~~~~~~~~~~~~~~~~ |
I guess we could just move that I would expect for Node.js CI and libuv CI to behave the same too, though. |
Perhaps a different level of compiler is being used. There are lines like this for AIX, e.g., https://ci.nodejs.org/job/node-test-commit-aix/nodes=aix61-ppc64/14325/console ccache /home/iojs/gcc-6.3.0-1/opt/freeware/bin/gcc ... which would indicate gcc 6.3.0 bring used -- @mhdawson is this expected? The most recent updates in nodejs/build#925 suggest the upgrade to gcc 6.3.0 is still in progress. |
We really need to try to get this landed today before I do the first RC build. I will be kicking off that build this afternoon between 1 and 2 pm pacific. |
I think I've worked out why the libuv AIX CI passed and the Node.js AIX CI is failing -- I think libuv is building 32-bit code while Node.js is building 64-bit. The following is a reduced test showing the difference (I believe -bash-4.4$ cat test.c
#include <stdio.h>
#include <semaphore.h>
int main(int argc, void* argv)
{
printf("sizeof sem_t %i\n", sizeof(sem_t));
printf("sizeof void* %i\n", sizeof(void*));
printf("static assert %i\n", 1-2*!(sizeof(sem_t) >= sizeof(void*)));
return 0;
}
-bash-4.4$ gcc -o test test.c # 32-bit
-bash-4.4$ ./test
sizeof sem_t 4
sizeof void* 4
static assert 1
-bash-4.4$ gcc -o test -maix64 test.c # 64-bit
-bash-4.4$ ./test
sizeof sem_t 4
sizeof void* 8
static assert -1
-bash-4.4$ This seems to suggest that the following comment won't work on 64-bit AIX as the /* To preserve ABI compatibility, we treat the uv_sem_t as storage for
* a pointer to the actual struct we're using underneath. */ cc @addaleax |
We just moved up the compiler levels for 10.x (not just for AIX) so it is expected that mater is using a newer compiler. We'll have to see if the requirements for libuv have been moved up as well and we should use the newer compiler as well. That may or may not be the case will need to get input from libuv maintainers, but I think that should be in a different thread. |
@gireeshpunathil can you take a look as well if this is not resolved by the time you get in. |
@mhdawson I believe the compilers being different was a red herring and the main issue is that libuv doesn't actually appear to have support for compiling 64-bit binaries on AIX (I can't find any |
@richardlau ok, so we should open an issue to have the job in the libuv CI to be 64 bit instead of 32 bit. Can you do that. There still needs to be a solution to the compile failure though. |
@mhdawson I've raised nodejs/build#1245 but it needs libuv/libuv#1807 to land first so that libuv can pass through the right compile and link flags. |
I mean, leaving all the CI stuff aside, is there anything wrong with the suggestion from #20129 (comment)? If yes, then we can still just disable the |
Sorry about being distracted with the CI. The suggestion looks okay to me. |
Raised libuv/libuv#1808 as per #20129 (comment). |
Is this on track to land by monday afternoon? |
Pass -Dtarget_arch=ppc64 to gyp_uv.py to activate.

On 64-bit AIX `sizeof(uv_sem_t)` is 4 bytes which is not large enough to store a pointer. AIX doesn't use glibc so the work around introduced by #1795 doesn't apply, so guard the STATIC_ASSERT so that it is only used when the custom semaphore implementation is used.

Landed the relevant PRs in libuv. Here is a CI run of current Node master and libuv 1.x. macOS hasn't finished yet, but so far everything else is green. I can cut a 1.20.2 release to replace this PR before Monday afternoon (cc: @bnoordhuis @santigimeno). UPDATE: macOS finished. It doesn't look like there were failures, but |
This has been updated to libuv 1.20.2. CI: https://ci.nodejs.org/job/node-test-pull-request/14426/ |
CI is green except for #18435. This should be good to go. |
