Description

This may or may not be much of a task, just making some notes about setup issues on my new less-explodey laptop. Most of these problems are of my own making because I didn't read the setup instructions I wrote.

(I also got the old one fixed and it is no longer an explosion risk.)

Cache

I get this junk when trying to access an instance:

Unable to open lock '/Users/epriestley/dev/core/tmp/cache/cluster/locala._www.almanac.cache.lock' for writing!

This is because of user account vs apache permission issues.

I might get rid of this cache (at least partly?) as part of caching changes in T13076, if we're lucky.

As a workaround, I created this file and chmod 666'd it. This isn't great.

Another alternative is maybe letting a temporary directory be configured, and just using <system temp dir>/phacility on local installs. We use /core/tmp instead of /tmp in production to keep the data off the tiny / mount.

I think "not reading" also comes into play here. The official instructions say to chmod o+w the tmp directory. It would be nice to find a cleaner fix for this but I'm punting until after cache changes in T13076.

Conduit Public Key

I skipped the actual setup instructions and hit this:

ERR-INVALID-AUTH: No user or device is associated with that public key.

This could be a little more helpful by showing the public key, which is public. I also think I don't have a public key configured? Let me see...

Following the instructions (creating @instance-client and adding the right key) fixed this.

pcntl

The default version of PHP on macOS doesn't have pcntl so you can't start the daemons. I don't think we can handle signals without this and we realistically need to handle signals.

So we must choose among three great evils:

  1. Put brew on the machine.
  2. Build PHP from source with --enable-pcntl or whatever?
  3. Build just the extension from source?

I'll try (3) and then probably give up and install brew if that doesn't pan out since I haven't actually needed to build php recently and approaches (3) and (1) both fight with the macOS version of PHP.

Build just the extension from source?

Here's how to do this:

  • Install XCode. Find the secret "Install Command Line Tools" option inside the Hidden Chamber of XCode and click it. You may already have done this. We're doing this to get autoconf, a utility written in 1975 for automatically generating a file for a utility written in 1973 to use to generate a file for another utility written in 1971.
  • Never mind, this option no longer exists.
  • This doesn't appear to install autoconf.

Okay:

  • Download the autoconf source?
  • ./configure + make + sudo make install
  • Seems okay?

Now:

  • Download PHP source.
  • cd php-<verison>/ext/pcntl
  • phpize
  • ./configure + make + sudo make install
  • What is this???
$ sudo cp modules/pcntl.so /usr/lib/php/extensions/no-debug-non-zts-20160303/pcntl.so
cp: /usr/lib/php/extensions/no-debug-non-zts-20160303/pcntl.so: Operation not permitted

Apparently SIP? Okay fine:

extension=/Users/epriestley/src/php-7.1.19/ext/pcntl/modules/pcntl.so

Secure!

xcode-select --install should be possible without a full XCode installation.

I made it as far as locala.phacility.com working right so maybe I got everything?
