Mac homebrew users

[Dave Cottlehuber <da...@muse.net.nz>]

Hi folks,

A while ago Filipe found & documented[1] an issue with Apple's OpenSSL
implementation that causes segfaults and bus errors when running with
Erlang. This was pre-Lion but some of us are still having trouble with
it.

I've been working on improving the Homebrew recipe to accommodate this
as well as the option to install CouchDB development branch directly.

Unfortunately I haven't got it all working but the code is here [2]
and it would be great if somebody has a go at this & lets me know
what's missing.

brew update
brew remove --force erlang nspr openssl couchdb spidermonkey
## apply patch from [2]
brew install -v --64-bit openssl
brew install spidermonkey
brew install erlang
brew install --devel couchdb
A+
Dave

Hi everybody,

TL;DR:
New couch & openssl recipes submitted to homebrew & gist[1],
also on my fork[2].
Assuming these are accepted, you'll need to:

# cleanup
brew update
brew remove --force openssl erlang couchdb icu4c spidermonkey nspr

# install pre-reqs
brew install icu4c openssl

# ensure we build against the new keg-only versions
brew link icu4c openssl
brew install erlang --no-docs
brew install couchdb [--devel]

#optional --devel will track 1.2.x vs 1.1.1 by default

And hopefully use 1.2.0 as default very soon too!

TL:
After more testing using a script[3] from davisp, I can see that the new
recipe is significantly more stable *but* still occasionally crashes -
around 1 time in 1.5 hours of heavy testing, and that it's not related
to the openssl version used as I can use 1.0.1 just as effectively.

Benoît and & have been using the OpenSSL 1.0.0x series for a while
in the windows & refuge build for some time now, so I've sent a pull
request to homebrew to accommodate this instead, with automatic
detection of using 64 bit or 32 bit builds as required by your platform.

This seems stable enough for my dev needs but feel free to dig further.

Should I raise this on erlang-bugs maybe as well?

No, and I'm pretty sure I'll come back scarred (but a better
programmer) if I did tho.

I have this working now on Lion, https://gist.github.com/2147079 with
updated patch
& instructions.

Relax (YMMV).
A+

I've not looked into this thoroughly but has anyone thought to try
patching Erlang to use the newer openssl?

It is not pre-lion. Lion introduced this change.

Thanks! Tough it would be better imo if openssl is detecting the
platform, so erlang could use the same imo :)
