Tests 2056 and 2057 failing on macOS

[jakirkham]

When building curl 7.58.0 on macOS 10.10 using Xcode 6.4, seeing tests 2056 and 2057 fail. Details can be found in this build log (linked to failing lines). Can confirm that these failures also occur on macOS 10.11 with Xcode 7.3.1. Also can confirm the issue persists in 7.59.0.

Unclear as to whether this comment is relevant.

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.

[jakirkham]

AFAIK this issue remains unresolved.

But nobody seems to work on it, why this is silent and the bot marked it as stale. Bugs that don't "move" will get closed eventually and will instead get added to the KNOWN_BUGS document.

Is it possible to get error logs and not just the FAILED` lines? I only have access to 10.13 but I can try and reproduce once I know what I'm looking for.

Ah! Was not aware there was a known bugs doc. Is that in this repo or somewhere else? Also would be great if the bot shared this info when posting as well.

The log is linked in the OP. It selects specific lines, but you are free to move around in the log as well as remove the selection. Please let me know if you have more questions.

The buildlog is there yes, but I would like to see the actual logfiles/output from the failing tests.

would be great if the bot shared this info when posting as well.

It is mentioned in the "new issue" template. It was in that text you just skipped over =)

[jakirkham]

Hmm...I may have read it 6 months ago and forgot. :) In any event, would still be nice to have the bot mention it. ;)

@danielgustafsson, not sure I'm following. Can you please tell me how to get the additional information you need? We may need to try a new build to get at it. Happy to update the build to cat whatever files might be useful into the log.

I took a look at this today, and the reason why the tests are failing on macOS is that they depend on LD_PRELOAD, which doesn't work on macOS. There is actually code in runtests.pl to properly skip the tests in this case, but that codepath has a bug which doesn't exclude macOS from LD_PRELOAD and thus you are seeing this error. A fix proposed in #3106.

A longer term fix is to make this portable such that it uses DYLD_INSERT_LIBRARIES on macOS, but some quick testing shows that it's not as simple as the below diff so I'll add this to the TODO for now.

-LD_PRELOAD=%PWD/libtest/.libs/libstubgss.so
+DYLD_FORCE_FLAT_NAMESPACE=1
+DYLD_INSERT_LIBRARIES=%PWD/libtest/.libs/libstubgss.dylib
