That's a shame. @genotrance any chance you could take a look?

metasyn · 2019-06-12T00:02:54Z

Happy to help debug if there is anything I can do

Seems like this is where the crash is coming from:

Can you look into that code and debug why that's nil?

genotrance · 2019-06-13T14:43:26Z

Sorry I've not had OSX access for some time, but feels like an SSL setup issue. Might be worth checking which version of openssl is present, updating with brew, and checking the order of versions in the Nim openssl wrapper.

metasyn · 2019-06-13T18:37:16Z

Hmm - it could be - here is my version:

❯ openssl version
OpenSSL 1.1.0j  20 Nov 2018

At the end of httpclient.nim, I added:

when isMainModule:
  let j = getDefaultSSL()

with no error when I run it.

When I check the the wrapper (lib/wrappers/openssl.nim):

  when defined(osx):
    const versions = "(.1.1|.38|.39|.41|.43|.44|.45|.46|.10|.1.0.2|.1.0.1|.1.0.0|.0.9.9|.0.9.8|)"
  else:
    const versions = "(.1.1|.1.0.2|.1.0.1|.1.0.0|.0.9.9|.0.9.8|.46|.45|.44|.43|.41|.39|.38|.10|)"

When I build and test the wrapper:

which looks like it could be part of the issue. I'll try changing some openssl stuff and see whats going on...

dom96 · 2019-06-13T20:08:52Z

I don't think that's an issue, don't mess with --dynlibOverride. Do try using httpclient and see if you can reproduce this.

metasyn · 2019-07-12T02:11:37Z

I've since moved to using a different computer (also macOS) which does not have this problem. I'm going to chock it up to my weird setup on the old machine and close; someone else can re-open if this becomes an issue or something :)

Thanks!

Milerius · 2019-12-13T20:47:19Z

@dom96

can we reopen:

dom96 · 2019-12-13T23:06:53Z

@Milerius can you have a look at the above posts by me and the original author and see if you can reproduce by using httpclient? (you can install Nim some other way to try compiling a program which uses httpclient).

genotrance · 2020-01-11T23:45:37Z

I just tried on Mojave with openssl 1.1.1d and it all works fine. This is with Nim 1.0.4 and choosenim 0.5.0+.

dom96 · 2020-01-12T14:33:31Z

We need a debug build of choosenim so that we can ask users who receive such crashes to try it and give us a stack trace.

genotrance · 2020-01-12T17:07:39Z

--debuginfo --debugger:native or just no -d:release / -d:danger?

dom96 · 2020-01-12T17:52:50Z

just no -d:release / -d:danger

Just this.

genotrance · 2020-01-12T18:13:34Z

Okay, I'll add it to the CI and debug builds will get posted for every release.

genotrance · 2020-01-13T20:52:38Z

PR #160 now posts debug builds. Next minor release will have debug builds which can be used for such issues going forward.

timotheecour · 2020-01-19T20:25:28Z

this bug affects github actions installing nim, which affects nimble packages like glob, eg see Revert "fix: normalize input paths (#37)" haltcase/glob#43 (comment)
this issues doesn't occur on my osx catalina (10.15.2 ) but might be depending on environment
on an older OSX sierra 10.12 it gave additional warning msgs:

EDIT

after instrumenting the sh file to instead use debug build choosenim-0.5.1_macosx_amd64_debug I get:

Is there another way I can update nim to the latest without building ? Should I use brew ?

genotrance · 2020-01-27T15:49:35Z

On OSX, we do not ship official binaries yet, it has to be built even with choosenim. I'm not sure if Nim is in brew or what version it is at either, easiest is to build from source - shouldn't take too long.

nixfreak · 2020-01-27T16:20:16Z

Ok thanks for the fast update

nixfreak · 2020-01-27T18:20:29Z

Not sure if this is relevant or not but I have pasted below the build script using brew on Osx.
brew doesn't have the latest release, after this I will edit the ruby files and build again.

Didn't work , I did something wrong , just going to build instead.

dom96 · 2020-01-27T23:15:24Z

So this is the line that is crashing: https://github.com/nim-lang/Nim/blob/devel/lib/pure/net.nim#L543

I wonder if some versions of macOS have an OpenSSL which disallows this. @nixfreak what's your macOS version? Can you try the following code and see whether it works for you?

import httpclient
let client = newHttpClient()
echo(client.getContent("https://google.com")

Make sure to compile with -d:ssl.

dom96 · 2020-01-28T21:50:50Z

That's odd and suggests to me that there may be a bug in how choosenim was built.

nixfreak · 2020-01-29T14:37:37Z

Yeah I still can't install via choosnim I had to build nim and now I have 1.1.1 installed.
Is there anyway we can install multiple versions of nim on one system? Sort of of like a virtualenv ? Then I can test quite a bit.

genotrance · 2020-01-31T17:17:30Z

#139 is also similar.

genotrance · 2020-01-31T18:50:39Z

I did some additional testing and was able to reproduce this issue.

My macOS 10.14.6 with clang 11.0.0 has LibreSSL 2.6.5 installed in /usr/lib. That is what I get when I run openssl version. Both libssl.dylib and libcrypto.dylib are linked to libxxx.35.dylib, whatever that version means. I also have 0.9.7, 0.9.8, 41, 42, 43 and 44 in the folder. The Nim openssl wrapper loads libxxx.dylib first so v35 is getting loaded and it all works.

Now, brew has installed two additional versions of openssl in the cellar, 1.0.2s and 1.1.1.d. I tried testing both those versions with export DYLD_LIBRARY_PATH=/usr/local/opt/openssl@1.x/lib, one at a time, and could get the system to crash with 1.1.1.d as reported but it works fine with 1.0.2s.

I don't know why this version of openssl is not working with choosenim but hope someone has some ideas to proceed here.

timotheecour · 2020-01-31T19:00:36Z

@genotrance did you see #122 (comment)

which means error isn't caught here, which points to your code @genotrance :)

there could be more than 1 bug involved here, potentially.

genotrance · 2020-01-31T19:12:13Z

Yes but I focused first on the openssl variation since that's been reported more often.

genotrance · 2020-01-31T20:24:47Z

As suggested by @timotheecour in IRC, I recompiled choosenim with openssl 1.1.1d as the active version using DYLD_LIBRARY_PATH and it compiled fine. However, it crashes in that window just like before.

If I switch to another window using the default libressl version or the openssl version of 1.0.2s, it works again. So it doesn't matter what version of library we build against, only runtime matters.

It appears our Nim openssl wrapper has some bug with the 1.1.1d version of openssl on OSX.

I spent a ton of time on openssl crap. My opinion openssl project breaks their API all the time but you are forced to use it, as it's practically part of the os. Just find nim-openssl pairing that works and stick with it. It's very fregile. It's easy to get openssl microversion that is not compatible or just plain buggy.

genotrance · 2020-02-01T05:13:10Z

This is a duplicate of nim-lang/Nim#9419 and can be tracked there. Just replace libpq with libcurl in this case.

dom96 · 2020-02-07T21:18:57Z

This is a duplicate of nim-lang/Nim#9419 and can be tracked there. Just replace libpq with libcurl in this case.

So the root cause is loading libcurl + openssl in the same program (where libcurl loads a different openssl version)? We should start a bug hall of fame just for this :)

Thank you for testing this @genotrance, can you confirm by compiling choosenim without libcurl and see if that fixes the problem? (you can just comment this out to do that: https://github.com/dom96/choosenim/blob/master/src/choosenim.nims#L2).

genotrance · 2020-02-09T04:53:27Z

can you confirm by compiling choosenim without libcurl and see if that fixes the problem?

Just tried this test and it works fine without libcurl. Compile it back in and it crashes again.

genotrance · 2020-02-13T03:21:08Z

As mentioned in the Nim issue, we can fix this quite easily for choosenim.

OT: but especially for CI/headless environments, shouldn't the analytics prompt be opt-out by default, or can a -n flag be passed.
