Selenium-RC and Snow Leopard

sam — Sun, 21 Feb 2010 00:47:34 +0000

Selenium-RC was having issues on Snow Leopard:

 
dyld: Library not loaded: /usr/lib/libsqlite3.dylib
Referenced from: /System/Library/Frameworks/Security.framework/Versions/A/Security
Reason: Incompatible library version: Security requires version 9.0.0 or later, but libsqlite3.dylib provides version 1.0.0

Web searches produced a lot of information including some workarounds that didn’t. Finally I read that Selenium-RC 1.x has some hardcoded paths in it that mean it won’t work with Snow Leopard, and you need to get the Selenium-RC 2.x jar (alpha at this time). The easiest way to do this is to install the selenium-rc gem that Pivotal packaged.

[Update]

More recently, have been having issues running Cucumber/Webrat/Selenium on new MacOS systems. It turns out that Webrat contains an out-of-date version of the selenium server jar file. If you are using Webrat, you need to copy the good selenium-server.jar from the selenium-rc package over the version contained in the Webrat gem. Something like:

 
sudo cp /Library/Ruby/Gems/1.8/gems/selenium-rc-2.2.1/vendor/selenium-server.jar /Library/Ruby/Gems/1.8/gems/webrat-0.7.0/vendor/selenium-server.jar

Completely uninstall mysql from Mac OS X

sam — Thu, 14 May 2009 23:54:42 +0000

Remove mysql, prefpane item, startup item.
then:

sudo rm -rf /Library/Receipts/mysql*

There is a good complete explanation of this here.

Mac OS X command-line launchd control of mysql

sam — Thu, 14 May 2009 23:45:57 +0000

To start, stop and disable mysql server from the command line:

# start
sudo launchctl start com.mysql.mysqld
# stop
sudo launchctl stop com.mysql.mysqld
# Unload
sudo launchctl unload /Library/LaunchDaemons/com.mysql.mysqld.plist

Terminal.app custom tab names

sam — Tue, 28 Apr 2009 05:07:24 +0000

So it turns out you can have the best of both worlds. I have been using ITerm for a while because it allows me to rename its tabs. Chad just turned me on to a hack that makes the same thing possible with Terminal.app:

1. Install SIMBL: http://www.culater.net/software/SIMBL/SIMBL.php

2. Install TabNamer.Bundle: http://ericanderson.us/2008/03/02/terminalapp-tab-namer-v01-alpha/
a. download & unzip
b. move TabNamer.Bundle to ~/Library/Application Support/SIMBL/Plugins

MacOS Leopard bash echo not interpreting escape sequences

sam — Thu, 16 Apr 2009 22:58:56 +0000

I just hit this incredibly retarded irritating gotcha in Mac OS Leopard. Luckily, unlike this poor bastard, it only cost me an hour.

Bash echo is supposed to interpret \ escape sequences (e.g. \n) if you supply it a -e flag. This works from the command line. It works in shell scripts. It works in ’system’ commands inside rake scripts. Unless of course you ssh into the very same system and run the same rake script; then it stops working.

I tracked this down to the COMMAND_MODE=legacy environment variable, which if missing (and it is missing if I ssh in) makes Leopard do all sorts of stupid Single UNIX Specification Version 3 (SUSv3) compatibility crap. As Stephen points out, this even breaks GNU autoconf scripts! Way to go, Apple – talk about missing the point completely.

iStat menus

There appear to be a couple of different iStat applications. You want this one.

Increasing RubyMine memory usage

sam — Mon, 15 Dec 2008 18:33:34 +0000

After a long search I figured out how to increase the memory available for RubyMine on MacOS:

In RubyMine.app/Contents/Info.plist

Find:

>VMOptions>
>-Xms16m -Xmx192m ...

Xmx is maximum memory to use.

LockScreen icon in menu bar on MacOS X

How to add an icon in your MacOS X menu bar (a la System Tray) that will allow you to lock the screen:

-> Preferences -> General -> Show Status in Menu Bar

Installing Ruby MySQL gem on Mac OS X Leopard

sam — Wed, 01 Oct 2008 13:24:30 +0000

Thanks to this post, I discovered how to install the MySQL ruby gem on Mac OS X:

You must be using the x86 variant of MySQL, not x86_64, apparently. Then:

sudo env ARCHFLAGS="-arch i386" gem install mysql -- \
--with-mysql-dir=/usr/local/mysql --with-mysql-lib=/usr/local/mysql/lib \
--with-mysql-include=/usr/local/mysql/include

SchemaSpy with MySQL on Mac OS X

sam — Sun, 28 Sep 2008 19:16:07 +0000

To get SchemaSpy working on Mac OS X, I:

Downloaded the latest SchemaSpy, schemaSpy_4.0.0.jar

Installed GraphViz using MacPorts

sudo port install graphviz

Installed the MySQL JDBC drivers using MacPorts

sudo port install mysql-connector-java

Ran it like this:

java -jar schemaSpy_4.0.0.jar -t mysql -dp /opt/local/var/macports/software/mysql-connector-java/5.0.7_0/opt/local/share/java/mysql-connector-java-5.0.jar -o <outputdir> -host localhost -db <dbname> -u <username> -p <password>
