Compiling the IMAP extension for PHP 5.3.15 with OS X 10.8.3

I have been testing the Drupal support module locally which features the ability to create tickets from email messages to an IMAP inbox. It requires the imap_open() PHP function provided by the imap PHP extension, which unfortunately is not included in the OS X builds of PHP.

ivucica has published a wonderful script to his blog that compiles the IMAP extension without having to recompile PHP entirely, but unfortunately it was not working for me and nobody else seemed to have my problem either. Compiling the imap library and PCRE went very smoothly, but when it came time to build the PHP extension this error appeared during ./configure:

checking whether build with IMAP works... no
configure: error: build test failed. Please check the config.log for details.

Well, crap. I check config.log and determine it's a linking failure:

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I couldn't figure out why it wasn't picking up the symbols from libssl, even when manually trying to compile said file and adding a -lssl flag.

After an hour of struggling with it and my debugging efforts going nowhere, I try adding -lcrypto for the hell of it and it works!

tl;dr, if you get this error then simply replace the following line of the aformentioned script:

./configure --with-imap=/usr/local/imap-2007f --with-kerberos --with-imap-ssl

With the following line that adds the required linker flags:
LDFLAGS="-lssl -lcrypto" ./configure --with-imap=/usr/local/imap-2007f --with-kerberos --with-imap-ssl

That's it!

Syncing your iOS device (either iPod, iPhone or iPad) with multiple iTunes libraries

With Apple's changes surrounding iCloud, managing media on iOS devices has become much easier and it is no longer absolutely bound to a single computer. However, I have still found it tricky to sync a single iOS device with multiple computers (different iTunes libraries) without having to entirely wipe the device first.

I synchronize my iTunes library between two computers regularly, so both machines have up-to-date copy of all media files. Furthermore, I set them up with the same username (but different hostname), so the iTunes media file paths are identical between machines.

Searching Apple forums revealed this solution by turingtest2: apparently, each iTunes library is assigned a randomly-generated "library ID". This identifier is stored on the iOS device, so if it doens't match when connecting to a new computer, it will request to wipe the device before proceeding with the sync. Simply copying my entire ~/Music folder from one machine to the other was enough copy all the iTunes metadata (including the library ID) and my device now happily synchronizes on either machine. For those wanting to save time and not copy their entire ~/Music folder, see the forum post for the exact files you'll need to copy.

Reset sync history in OS X Lion without using iSync

In previous version of OS X, the iSync application could be used to reset sync history. This technique often resolved a bunch of miscellaneous bugs and sync-related problems. The iSync application has since been removed in OS X Lion and Apple's support documents aren't of much help. This one claims that resetting sync services can be performed from iSync in Leopard and from the Sync menu extra in later version of OS X. This document describes how to enable the menu extra in the MobileMe settings. Besides the fact that MobileMe is deprecate and no longer in use, the option described in that document to enable the Sync menu extra only appears after signing in to MobileMe... Which is deprecated.

Fortunately, there's a hidden folder you can open to enable any menu extra manually! Open Finder and select Go > Go to Folder (or press Command+Shift+G). In the prompt that appears, type: /System/Library/CoreServices/Menu Extras/. This should bring you to a folder with a bunch of menu extras that you can double-click to add to the menu bar. The one of interest in this case is Sync.menu, which should appear in your menu bar a second or two after opening it.

Once it's in your menu bar, hold Alt/Option and click on it to expose the advanced options and click "Reset Sync Services". After that's done, you can remove it from your menu bar if you'd like by holding Command and then clicking & dragging it out from the menu bar.

Disable Time Machine's local snapshots feature

Lion introduced a new Time Machine feature the OS would automatically create local snapshots of files so that even without a backup disk attached, you could still enter time machine and recover or undo changes to certain files. As your disk space becomes low, this space is automatically freed and the rate of snapshot creation is reduced.

This is great on desktops and I would assume the newer Macbook Pros that have better disks, but on my older MacBook Pro I've noticed that Safari has had trouble loading web pages and during this time, I hear the disk thrashing for about a minute or so and then all of a sudden the page loads. After a bit of researching and some help from the 'fs_usage' command, I discovered that a process called 'mtmd' was accessing the filesystem often and it turns out that mtmd is responsible for creating these local time machine snapshots. A quick Google revealed how to disable the local snapshot functionality:

sudo tmutil disablelocal

We'll see if that helps the disk thrashing! I did immediately recover 1GB of disk space though which is a good sign.

Installing the Darwin Calendar Server 2.4 on Fedora 13 or Fedora 14

As I mentioned in my last post, I've been playing with the Darwin Calendar Server (DCS) on Linux... Today I was able to re-test my setup notes to see if they worked properly, so below I've written a tutorial on how to get your own DCS server going on Fedora 13 or 14.

Installing Dependencies

Since we will be installing CalendarServer directly from the 2.4 branch subversion repository, the first thing to do is to install subversion and the dependencies for DCS:

su -
# Required to check out the source code from the repository
yum install subversion
# Dependencies
yum install patch memcached krb5-devel python-zope-interface PyXML pyOpenSSL python-kerberos
# Requirements for compiling xattr
yum install python-setuptools gcc gcc-c++ python-devel

Enable extended file attributes (xattrs)

DCS requires user extended file attributes so the user_xattr mount option must be enabled for the partition on which CalendarServer will be storing its documents and data (in this case, /srv). If you have not already enabled this option (it is disabled by default), edit /etc/fstab and add the user_xattr mount option after defaults, for example:

/dev/mapper/VolGroup-lv_root /                       ext4    defaults,user_xattr        1 1

Grab DCS from SVN and run auto-setup

Once these packages have been installed and extended file attributes have been enabled, we will begin setting up the CalendarServer as your regular, non-root user.

# Directory to hold CalendarServer checkout and its dependencies
mkdir CalendarServer
cd CalendarServer
# Checkout the code from the repo
svn checkout http://svn.calendarserver.org/repository/calendarserver/CalendarServer/tags/release/CalendarServer-2.4 CalendarServer-2.4
cd CalendarServer-2.4
# Start auto-setup
./run -s

Auto-setup will now attempt to grab any missing dependencies for CalendarServer an will unpack and patch them accordingly. You may find that the download for PyDirector stalls - if so, hit to abort setup and download it manually:
pushd ..
wget http://downloads.sourceforge.net/pythondirector/pydirector-1.0.0.tar.gz
tar xfz pydirector-1.0.0.tar.gz
popd
# Resume unpacking
./run -s

Prepare for installation

Since DCS bundles a modified version of Twisted as well as a few other projects (such as pydirector), we will now prepare an installation root folder to avoid conflicts with system libraries (i.e., Twisted if it has been installed from the Fedora repos). This code will be run as root.

su -
# setup data & document roots
mkdir -p /srv/CalendarServer/{Data,Documents}
chown -R daemon:daemon /srv/CalendarServer/
# setup installation root
mkdir -p /opt/CalendarServer/etc/caldavd
mkdir -p /opt/CalendarServer/var/run/caldavd
mkdir -p /opt/CalendarServer/var/log/caldavd

Install DCS and configure the server instance

The last step is to install DCS from the Subversion checkout we made earlier into the installation root. Replace /home/regularuser with the actual path to the home directory of your regular user.

# install DCS to installation root
cd /home/regularuser/CalendarServer/CalendarServer-2.4
./run -i /opt/CalendarServer
rm -rf /opt/CalendarServer/usr/caldavd/caldavd.plist
# copy sample configuration files
cp conf/servertoserver-test.xml /opt/CalendarServer/etc/caldavd/servertoserver.xml
cp conf/auth/accounts.xml /opt/CalendarServer/etc/caldavd/accounts.xml
cp conf/caldavd-test.plist /opt/CalendarServer/etc/caldavd/caldavd.plist
cp conf/sudoers.plist /opt/CalendarServer/etc/caldavd/sudoers.plist
# change permissions; passwords are stored plaintext!
chmod 600 /opt/CalendarServer/etc/caldavd/*

I have reported bugs #390 and #391 about problems with the setup script on 64-bit machines as well as a problem if a custom destination installation directory is used (which we did). This bit of code works around both of the bugs:
# 64-bit fix - see https://trac.calendarserver.org/ticket/391
sitelib="$(python -c 'from distutils.sysconfig import get_python_lib; print(get_python_lib())')"
sitearch="$(python -c 'from distutils.sysconfig import get_python_lib; print(get_python_lib(1))')"
if [ "$sitelib" != "$sitearch" ];then
  mv /opt/CalendarServer"${sitelib}"/twisted/plugins/caldav.py* /opt/CalendarServer"${sitearch}"/twisted/plugins
  # PYTHONPATH fix for 64-bit - see https://trac.calendarserver.org/ticket/390
  sed -i.orig 's|PYTHONPATH="'"${sitelib}"'|DESTDIR=/opt/CalendarServer\nPYTHONPATH="${DESTDIR}'"${sitelib}"':${DESTDIR}'"${sitearch}"':|' /opt/CalendarServer/usr/bin/caldavd
else
  # PYTHONPATH fix for 32-bit - see https://trac.calendarserver.org/ticket/390
  sed -i.orig 's|PYTHONPATH="'"${sitelib}"'|DESTDIR=/opt/CalendarServer\nPYTHONPATH="${DESTDIR}'"${sitelib}"':|' /opt/CalendarServer/usr/bin/caldavd
fi

If you would like your server to use SSL (highly recommended), you will need to generate a certificate. If you have a certificate and key ready to install, place it in /opt/CalendarServer/etc/tls. If not, you can easily generate a free self-signed one:

# Generate SSL keys
mkdir /opt/CalendarServer/etc/tls
openssl req -new -newkey rsa:1024 -days 365 -nodes -x509 -keyout www.example.com.key -out www.example.com.crt

Now, edit /opt/CalendarServer/etc/caldavd/caldavd.plist in your favorite editor and configure the server as follows:
    <!-- Network host name [empty = system host name] -->
    <key>ServerHostName</key>
    <string>example.com</string> <!-- The hostname clients use when connecting -->

Try starting the server!

/opt/CalendarServer/usr/bin/caldavd -T /opt/CalendarServer/usr/bin/twistd -f /opt/CalendarServer/etc/caldavd/caldavd.plist -X

If all goes well, press to kill the process and then daemonize it:
/opt/CalendarServer/usr/bin/caldavd -T /opt/CalendarServer/usr/bin/twistd -f /opt/CalendarServer/etc/caldavd/caldavd.plist

Playing with the Darwin Calendar Server

Sorry for the lack of posts lately, I've been caught up with school and updating my FOSS on the side whenever I have some spare time.

The server that runs this site as well as diffingo.com and a few others is almost always idle - the load averages rarely exceed 0.5, and are most often sitting somewhere around 0.2 (it's a 1U/Core 2 Quad Q9550@2.83GHz/8GB RAM/2x1TB RAID 1). I have bigger plans for it in the future, but at the moment there just isn't a great deal for it to do since it handles everything so quickly.

I have been wanting to see how KVM VMs perform on it as well as try out the Darwin Calendar Server (DCS)... Seeing as DCS requires Python 2.5 and I didn't want to mess around with the live server's configuration (CentOS 5.x ships with Python 2.4), I installed Fedora 13 in a virtual machine so I could test the calendar server safely.

To my surprise, KVM works really, really well... I wasn't expecting that seeing as the versions I had used in Fedora were so much more recent. The performance is good - I haven't performed any stress-testing yet (which obviously will show a gap between the VM and running natively) but the DCS is running very smoothly and feels very responsive, so I'm confident that the difference in performance is not so large.

How I got the DCS running on Linux is a whole other story... I'll save that another post (F13/F14 DCS installation guides coming soon) but is it ever handy to have a CalDAV server! Previously, I was only able to sync calendars manually (with the USB cable) which made checking for homework assignments extremely annoying, as half of the information was always my iPod and the other half on iCal and I had to sync all the time. Now it's all over-the-air, so as long as there's Internet connectivity the calendar events can be pulled in or pushed out.

Fixing the iTunes 10 badness

I think many will agree that iTunes 10 was more of a marketing ploy than anything else... I found that iTunes 10.0 was worse than 9.x, primarily because of the "traffic light" style buttons in the window corner and graystyle icons. That was bearable though, and then the update to 10.0.1 came along made things even worse. No more Genius sidebar, and obnoxious "Ping" buttons every time a song is selected.

So I went on a quest to fix it, and found these commands on various forum threads and blogs:

(If you are unsure how to run these commands, quit iTunes and open Application > Utilities > Terminal. Copy/paste these commands in, hitting <Enter> after each to execute it.)

defaults write com.apple.iTunes hide-ping-dropdown 1
Disables the obnoxious "Ping" drop-down menu I mentioned earlier.

defaults write com.apple.iTunes show-store-link-arrows -bool TRUE
Restores the store arrow links present when a song is selected in 10.0 and earlier.

defaults write com.apple.iTunes disablePingSidebar 1
Disables the ping sidebar. Sadly, I haven't found a way to re-enable the Genius sidebar.

defaults write com.apple.iTunes full-window -boolean YES
Puts iTunes in "full window" mode, removing the traffic light window controls.

Now, the last thing is to restore color in iTunes. To do this, download the iTunes.rsrc file linked to in comment #7 on this thread. Next, right-click on iTunes in the Applications folder and select Show Folder Contents. Inside the Contents/Resources folder, copy the downloaded iTunes.rsrc file and opt to replace existing files when prompted. Restart iTunes and you should have coloured icons!

Note: If you're reading this but you're running iTunes on Windows, a user on Apple Discussions has posted how to do the same on Windows.

Some hidden gems in the iTunes 9 visualizer

It's more or less well known that the stunning visualizer in iTunes 9 is actually a modified version of The Barbarian Group's Magnetosphere. I recently downloaded a copy of the original magnetosphere visualizer, and one thing I enjoyed was the ability to control the amount and intensity of the particles (the glowing, moving dots). The following is displayed in the visualizer's help screen:

+/- Increase or decrease the intensity
A/S Add or Subtract particles (100 at a time)

While these commands are not listed in the help screen of the official iTunes version of the visualizer, to my surprise I found that they still work! They've proved useful for when the iTunes visualizer seems to get stuck for a bit with one of the big black stars blocking the view.

Installing PHP 5.2.10 on OS X 10.6 Snow Leopard

Since my update to Snow Leopard, I was pleasantly surprised to find that Apple has updated PHP to version 5.3 and also included the GD extension. While I no longer have to rebuild the extension manually like on Leopard, these changes to PHP brought around a different problem: Drupal is currently not compatible with PHP 5.3 (#360605).

I've been trying to get my local Drupal installations working, and although the patch from post #84 works pretty well (when applied to a D6 CVS checkout), Ubercart is still nonfunctional. Since I am currently building and testing Ubercart-enabled sites, my only remaining option was to downgrade to PHP 5.2.10. I wanted to have the same extensions and options that Apple's PHP 5.3 build had, so I started by viewing the output of phpinfo() and copying the configure command. To compile PHP, locally installed copies of libpng, libjpeg and pcre are required so let's started with that:

  1. (Like in the Leopard tutorial, I assume you have installed the Xcode & related developer utilities and that all downloads are saved in the "Downloads" folder in your home). Visit the libpng, libjpeg and PCRE homepages and download the latest release available for both. As of writing, the most recent releases are libjpeg 7, libpng 1.2.39 and PCRE 7.9.
  2. Compile libpng and libjpeg statically:
    cd ~/Downloads && tar xfz libpng-1.2.39.tar.gz
    cd libpng-1.2.39
    ./configure --disable-shared --enable-static
    make && make install DESTDIR=`pwd`/localinstall

    cd ~/Downloads && tar xfz jpegsrc.v7.tar.gz
    cd jpeg-7
    ./configure --disable-shared --enable-static
    make && make install DESTDIR=`pwd`/localinstall

    cd ~/Downloads && tar xfj pcre-7.9.tar.bz2
    cd pcre-7.9
    ./configure --disable-shared --enable-static
    make && make install DESTDIR=`pwd`/localinstall
  3. Since PHP will be built with MySQL support, download and install MySQL x86_64 for OS X. As of writing, the latest version is 5.1.38.
  4. Download PHP 5.2.10, available here
  5. Next, PHP needs to be prepared for compilation. As detailed in PHP bug #49267, a small change is required to get PHP to compile on Snow Leopard:
    1. Type in the terminal:
      cd ~/Downloads && tar xfj php-5.2.10.tar.bz2
      cd php-5.2.10
      nano ext/iconv/iconv.c
    2. Skip down to line 185 (Tip: <ctrl+c> shows current line)
    3. Remove the lib on #define iconv libiconv so that the code reads like this:
      #ifdef HAVE_LIBICONV
      #define iconv iconv
      #endif
    4. Hit <ctrl+o> and to save the file
    5. Hit <ctrl+x> to quit nano
  6. Now, PHP is ready for compilation. We will use a configure command relatively similar to the command extracted from phpinfo() earlier:
    ./configure '--prefix=/usr' '--mandir=/usr/share/man' '--infodir=/usr/share/info' '--disable-dependency-tracking' '--sysconfdir=/private/etc' '--with-apxs2=/usr/sbin/apxs' '--enable-cli' '--with-config-file-path=/etc' '--with-libxml-dir=/usr' '--with-openssl=/usr' '--with-kerberos=/usr' '--with-zlib=/usr' '--enable-bcmath' '--with-bz2=/usr' '--enable-calendar' '--with-curl=/usr' '--enable-exif' '--enable-ftp' '--with-gd' '--with-jpeg-dir=/Users/shortname/Downloads/jpeg-7/localinstall/usr/local' '--with-png-dir=/Users/shortname/Downloads/libpng-1.2.39/localinstall/usr/local' '--enable-gd-native-ttf' '--with-ldap=/usr' '--with-ldap-sasl=/usr' '--enable-mbstring' '--enable-mbregex' '--with-mysql=/usr/local/mysql/' '--with-mysqli=/usr/local/mysql/bin/mysql_config' '--with-mysql-sock=/tmp/mysql.sock' '--with-iodbc=/usr' '--enable-shmop' '--with-snmp=/usr' '--enable-soap' '--enable-sockets' '--enable-sysvmsg' '--enable-sysvsem' '--enable-sysvshm' '--with-xmlrpc' '--with-xsl=/usr' '--with-pcre-regex=/Users/shortname/Downloads/pcre-7.9/localinstall/usr/local'

    EXTRA_CFLAGS="-lresolv" make -j2
    Remember to replace shortname in /Users/shortname to your system account's shortname. If you're not sure what that is, type whoami in a terminal to find out.
  7. Finally, backup Snow Leopard's PHP extension so that PHP 5.3 can be restored later, and copy the PHP 5.2.10 extension in its place:
    sudo mv /usr/libexec/apache2/libphp5.so /usr/libexec/apache2/libphp5.so.orig106
    sudo cp libs/libphp5.so /usr/libexec/apache2/libphp5.so
  8. The final step is to restart Apache - this can be done by toggling Web Sharing in System Preferences, or alternatively via the apachectl command:
    sudo apachectl restart
  9. That's all! Now run phpinfo() and verify that PHP 5.2.10 is up & running. While I was trying to get this working, I stumbled accross two compile errors - for the sake of completeness, I've listed them below along with the failure cause:

    1. This error occurs if EXTRA_CFLAGS="-lresolv" is not used while compiling PHP:
