To use the php-trunk portsfile. Just extract the tarball into a directory and…

$ tar xzvf php-trunk-port.tar.gz
$ cd php-trunk-port
$ echo "file://`pwd`" > /opt/local/etc/macports/sources.conf
$ echo "file://`pwd`" >> /opt/local/etc/macports/sources.conf
$ port install php-trunk


And the best thing about the port: It compiles PHP with dtrace support :).

Please note the Portfile is very simple and is not tested with the additional modules provided by macports. So use it at your own risk and enhance it.

UPDATE: as philip noted, it should be >> instead of >.

To compile PHP with DTrace, on Solaris or Mac OS do:

  $ svn co http://svn.php.net/repository/php/php-src/trunk php
  $ cd php
  $ ./buildconf --force
  $ ./configure --enable-dtrace
  $ make

To check if your PHP has DTraces probes enabled, you can check the phpinfo() using

 $ php -i | grep DTrace

or use DTrace directly>

 $ sudo dtrace -ln 'php*:::' -c 'php -m'

Have fun with DTrace in PHP.

A few examples will follow in the next days.

• Dutch PHP Conference 2010
• Interntational PHP Conference

The talk will give a very brief overview how Git works, and will then give a more detailed insight in how Git handles commits, files, etc so that people get a very good understanding about the concepts that are needed to fully understand tools like git rebase, git reflog and git svn. The aim is to provide them will all necessary information and a few examples to get lost commits back, rebase their branches and design more complex git workflows in the future without needing to search the web or ask a guru.

A second talk will be more focused on beginners and developers coming from subversion. This talk will be part of a series of talks the german telekom is organizing. I’ll also give an extended version of this as an in-house workshop at a Munich based company.

So for me it seems that after five years, DVCS is mature enough to get into companies and that we can expect a bright variety of companies to adopt new tools and workflows. Let’s see what’s coming…

For sure I still offer Git and Mercurial trainings, so feel free to contact me (dsp ~at~ php ~dot~ net)

probably shameless self promotion

As I wanted to have nice a build system for my PHP subversion checkout, I used this need as a project to start coding Scala. So what do I exactly need? I want to build multiple versions of PHP from the same branch without checking out the code twice. I also want to configure these builds somewhere without always typing in the parameter list or so. For further versions I want to be able to configure these in a file that can easily be distributed to other machines.

I set down and wrote a parser for a configuration file that can configured build targets which is then build by
the program. The configuration file I used is specialized for this purpose, which is why I didn’t used something like ant or so. The result is called bauaffe-3.0.0a1.jar.

I’ll just show a few things done in the project, but mainly focus on what the nice script can do. Further blog posts will be about the actual implementation.

The configuration looks like this

$ cat ~/.buildmaker
begin default configuration
    define source "/Users/dsp/dev/c/php-src"
    define build "/Users/dsp/dev/c/php-src/build"
    define defaults as
        with "iconv=/opt/local"
    build trunk as
        "php60" using defaults
        "php60-debug" using defaults
            enable "debug"
    build branch "PHP_5_3" as
        "php53" using defaults
            environment PHP_AUTOCONF="autoconf213"
        "php53-debug" using defaults
            enable "debug"
            environment PHP_AUTOCONF="autoconf213"

.
Proper indention is not necessary (as e.g in python).

Did I mention that the actual parser is 170 lines of code with usual indention and formatting?

Configuration
The configuration file is searched in ~/.buildmaker, or if ~/.builmaker doesn’t exists, buildmaker.conf in the current directory. How do you configure the tool? First of all you can specify a configuration. It is usually called “default”. It is not yet supported to name it differently, although the parser is able to parse it. In further versions multiple configurations per file are allowed.

Variables
Variables are set using the define syntax. At the moment you can set the build and source variable as well the defaults variable, which is usually a block of statements that can be used in the branch configurations.

Branches
A branch is configured using the build syntax. You first have to specify which branch to build. Every branch can then configured to have build target with a given set of options. Branch options are:

• with string: Builds the target with the given extension
• enable string: Builds the target with the given extension
• environment string=string: Builds the target with environment variable

. You can specify using defaults which will cause the runner to use the options specified in the defaults define.

At the moment the parser will not do a good job in notifying you what you are allowed to do and what not, although pure parse error will be emitted. You can also not set any other variable than the described once.

Building
Calling

$ java -jar bauaffe-3.0.0a1.jar list
TARGET                         LAST BUILD
php60                          None
php60-debug                    None
php53                          Sat Jan 09 16:55:12 CET 2010
php53-debug                    Sat Jan 09 16:59:37 CET 2010

gives you a list of parsed targets and their last build date. You can build a target using

$ java -jar bauaffe-3.0.0a1.jar 

or build all using

$ java -jar bauaffe-3.0.0a1.jar all

Please notice that the current version requires that you now what you are doing. You might miss some error messages or find them not useful. I’ll change this before the first release, if I’ll do a final version of it. I hope you like the little tool.

Scala (pronounced /ˈskɑːlə, ˈskeɪlə/) is a multi-paradigm programming language designed to integrate features of object-oriented programming and functional programming.[1] The name Scala stands for “scalable language”, signifying that it is designed to grow with the demands of its users.

result ZEND_ADD_OPCODE()
{
   return add_function(get_op1(), get_op2());
}

Voila, that’s the problem. On SPARC get_op1() is executed before get_op2(), while it’s the other way round on x86. As get_opX() detects if a variable exists, the error messages appear in reversed oder. I did a little bit research (thank you SunCC Team for your answer!) and it turned out, that C99 doesn’t define the way function calls in parameter lists are executed. Therefore, every system and compiler is free to use it’s own ordering mechanism. My current plan: Write a compiler that does this by random(). The fix is trivial:

result ZEND_ADD_OPCODE()
{
  op2 = get_op2();
  return add_function(get_op1(), op2);
}

. It’s a lovely curiosity.

But there is a more elegant to get the same behavior. Using DTrace and recent OpenSolaris 2009.06 we are able to use the php:::error probe to get all error messages. Unlike the PHP extension we do not need to restart our PHP. We are also able to just temporarily look into the errors of all running PHP processes. Here is the DTrace script:

#!/usr/sbin/dtrace -s

php*:::error {
printf("Error \"%s\" in file %s line %d\n", copyinstr(arg0), copyinstr(arg1), arg2);
}


This will display all errors that occur. There is also a php:::exception-thrown probe which can provide nearly the same data for exceptions instead of errors.

No knowledge about C or PHP’s internals is needed. We will provide you with everything you need.
Check the wiki page for more information about the event. It’s definatly worth joining us.
