Upgrading from Phing 2.x to 3.0

Phing 3 is a significant update with some breaking changes compared to Phing 2.

This document aims to summarize all those breaking changes and noteworthy things that you might stumble across when upgrading from Phing 2 to 3.

  • Phing now requires at least PHP 7.3.
  • All Phing code is now namespaced. This means that existing references to classes that existed in earlier Phing versions will no longer work. For example, the class PhingFile has been moved to Phing\Io\File. If you are used to providing a specific logger or listener when running Phing (such as phing.listener.DefaultLogger), you will need to adjust this (to Phing\Listener\DefaultLogger, for example). The documentation has been modified to reflect this.
  • Support for dot-path classnames (i.e., foo.bar.FooBar) has been removed. The associated PackageAsPath task was also removed.
  • Omitting the basedir property in the root project tag now means "." instead of the current working directory. This effectively reverts the change made in http://www.phing.info/trac/ticket/309 (dfdb0bc)
  • The behavior of MkdirTask has changed to be same as of mkdir Linux command:
    • When using MkdirTask to create a nested directory including its parents (eg. <mkdir dir="a/b/c" />), the task now creates the parent directories with default permissions and not the permissions specified in mode attribute. Only the last directory in the created hierarchy (ie. "c" in "a/b/c") should have permissions corresponding to the specified mode attribute. Previously, MkdirTask used to apply the same mode to all the directories in the hierarchy including the last one.
    • When using MkdirTask with mode attribute, the newly created directory now has exact the permissions specified in mode attribute. If any parent directories are created, they have default permissions affected by umask setting. Previously, MkdirTask used to mask the permissions of the last directory in the hierarchy according to umask too.
    • These changes are also important for POSIX Access Control Lists (ACL) to work properly. When using ACL, the mask used to determine the effective pemissions corresponds to the standard group permissions. The ACL mask of a newly created directory should be inherited from the default ACL mask its parent directory. However, previously MkdirTask without mode attribute used mask the group permissions of newly created directories according to umask setting which resulted in lower than expected permissions. This should not happen when using ACL. Now, MkdirTask respects ACL settings.
  • The tasks to generate PEAR packages (including supporting code) have been removed from Phing.
  • [AppendTask] The default behavior of append attribute was changed to true
  • [MoveTask] The default behavior of overwrite attribute was changed to true
  • [PHPUnitTask] Support for PHPUnit 9.
  • [PhpCodeSnifferTask] was removed in favor of [PhpCSTask].
  • The Zend Guard tasks were removed (Zend Guard is no longer supported).
  • A number of tasks (or group of tasks) were moved to their own repositories, but are automatically pulled in / installed when you install Phing:
    • ApiGen
    • Code coverage
    • FtpDeploy
    • Git
    • Hg
    • IniFile
    • Ioncube
    • JsHint
    • JsMin
    • Liquibase
    • PhkPackage
    • PhpDoc
    • Smarty
    • SSH
    • Visualizer
    • ZendCodeAnalyser
    • ZendServerDevelopmentTools
  • The signature from \Phing\Listener\DefaultLogger::formatTime has been changed. Therefore, if you have written a logger that overrides this method, you will need to update its signature accordingly.
  • The way how Phing handles file sizes has been normalized, this is explained in documentation.
    • FileSizeTask: unit attribute can be an IEC or SI suffix.
    • HasFreeSpace condition: needed attribute can include an IEC or SI suffix.
    • Size selector: units attribute has been removed, value attribute can include an IEC or SI suffix.
    • TruncateTask: length attribute can include an IEC or SI suffix.
  • The way Phing handles and parses boolean values has changed significantly! In general, strings such as true, false, TRUE, FALSE, etc. are no longer parsed into their PHP native equivalent. Specifically:
    • The way how boolean values are handled inside tasks has been normalized. Therefore t is not a valid true value any longer. For a list of effected components follow https://github.com/phingofficial/phing/search?p=1&q=booleanValue
    • Boolean values (such as true and false) are no longer parsed when loading property files. Instead, the literal string value will be kept as property value.
    • Property expansion (such as through the ExpandProperties filter) also no longer handles boolean values as anything other than literal string values.
  • Obsolete ExportPropertiesTask was removed in favor of the EchoPropertiesTask 
    <exportproperties targetfile="output.props" />
<!-- is the same as -->
<echoproperties destfile="output.props" regex="/^((?!host\.)(?!os\.)(?!env\.)(?!phing\.)(?!php\.)(?!line\.)(?!user\.)[\s\S])*$/"/>
  • FileHashTask creates now a file by default
  • Deprecated scpsend alias for the ScpTask was removed
  • Deprecated command attribute for the ExecTask was removed, in favor of the executable attribute and arg nested elements: 
    <exec command="echo foo"/>
<!-- should become -->
<exec executable="/bin/echo">
    <arg value="foo"/>
</exec>
