does faketime 'now' /bin/bash -c 'echo $DYLD_INSERT_LIBRARIES'give any output?

$ faketime 'now' /bin/bash -c 'echo $DYLD_INSERT_LIBRARIES'
Caught Segmentation fault: 11

It seems to segfault every time, regardless of which binary is executed.

Could you please try building from source on macOS 10.11?

Actually, libfaketime 0.9.7 is supposed to run on Sierra (10.12) and High Sierra (10.13), but if it compiles cleanly on your El Capitan (10.11), it should work there also. Otherwise, v0.9.6 is recommended for El Capitan.

I've just seen that the official Homebrew build requires Lion only, while the brew formula we provide here requires Sierra. I guess we need to get that fixed if it doesn't work properly on El Capitan.

leonklingele commented 6 years ago

Sorry for the late response. Unfortunately, neither latest master, v0.9.7 nor v0.9.6 (compiled from source on OS X 10.11) produced a different result.

wolfcw commented 5 years ago

please try latest HEAD and reopen if it persists

@wolfcw can you reopen this please?

wolfcw commented 4 years ago

stat64("/path/to/libfaketime\0", 0x7FFF59ED56F0, 0x7FFF59ED5A20) seems strange in your dtruss output and it's unclear where that comes from.

Unfortunately, I have no test environment for OS X 10.11, and I cannot reproduce the problem on newer macOS versions.

leonklingele commented 4 years ago

/path/to/libfaketime is the path to where the libfaketime repo resides.

Is there any debug patch available so we can pinpoint the issue?

wolfcw commented 4 years ago

You can pass -DDEBUG when building libfaketime, but I doubt it will help much, as it seems to crash before anything from libfaketime is executed at all.

Maybe you could try to DYLD_INSERT_LIBRARIES libfaketime directly (see README.OSX) instead of using the faketime wrapper. If we're lucky, it's just the wrapper crashing but libfaketime itself working.

Otherwise, maybe a diff between a dtruss run with and a dtruss run without libfaketime inserted might give a clue.

wolfcw commented 3 years ago

sorry, giving up on this.

DanielSmedegaardBuus commented 3 years ago

This seems like it's upstream, as I'm having the same issue with MacPorts-provided faketime on 10.10

EDIT: Oh, wait, this IS the upstream place :D

@leonklingele — did you find a previous version that works?
