Constructor & Destructor Documentation

◆ __construct()

core\update\code_manager::__construct	(		$dirroot = null,
			$temproot = null )

Instantiate the class instance.

Parameters

string	$dirroot	full path to the moodle app directory root
string	$temproot	full path to our temp directory

Member Function Documentation

◆ archive_plugin_version()

core\update\code_manager::archive_plugin_version	(	$folderpath,
		$component,
		$version,
		$overwrite = false )

Archive the current plugin on-disk version.

Parameters

string	$folderpath	full path to the plugin folder
string	$component
int	$version
bool	$overwrite	overwrite existing archive if found

Return values

bool

◆ debug()

core\update\code_manager::debug ( $msg )

protected

Raise developer debugging level message.

Parameters

string $msg

◆ download_file_content()

core\update\code_manager::download_file_content	(		$url,
			$tofile )

protected

Thin wrapper for the core's download_file_content() function.

Parameters

string	$url	URL to the file
string	$tofile	full path to where to store the downloaded file

Return values

bool

◆ download_plugin_zip_file()

core\update\code_manager::download_plugin_zip_file	(		$url,
			$tofile )

protected

Download the ZIP file with the plugin package from the given location.

Parameters

string	$url	URL to the file
string	$tofile	full path to where to store the downloaded file

Return values

bool	false on error

◆ get_archived_plugin_version()

core\update\code_manager::get_archived_plugin_version	(		$component,
			$version )

Return the path to the ZIP file with the archive of the given plugin version.

Parameters

string	$component
int	$version

Return values

string|bool false if not found, full path otherwise

◆ get_plugin_zip_root_dir()

core\update\code_manager::get_plugin_zip_root_dir ( $zipfilepath )

Detects the plugin's name from its ZIP file.

Plugin ZIP packages are expected to contain a single directory and the directory name would become the plugin name once extracted to the Moodle dirroot.

Parameters

string $zipfilepath full path to the ZIP files

Return values

string|bool false on error

◆ get_remote_plugin_zip()

core\update\code_manager::get_remote_plugin_zip	(		$url,
			$md5 )

Obtain the plugin ZIP file from the given URL.

The caller is supposed to know both downloads URL and the MD5 hash of the ZIP contents in advance, typically by using the API requests against the plugins directory.

Parameters

string	$url
string	$md5

Return values

string|bool full path to the file, false on error

◆ list_plugin_folder_files()

core\update\code_manager::list_plugin_folder_files ( $folderpath )

Returns list of all files in the given directory.

Given a path like /full/path/to/mod/workshop, it returns array like

[workshop/] => /full/path/to/mod/workshop [workshop/lang/] => /full/path/to/mod/workshop/lang [workshop/lang/workshop.php] => /full/path/to/mod/workshop/lang/workshop.php ...

Which mathes the format used by Moodle file packers.

Parameters

string $folderpath full path to the plugin directory

Return values

array (string)relpath => (string)fullpath

◆ move_extracted_plugin_files()

core\update\code_manager::move_extracted_plugin_files	(		$sourcedir,
			$targetdir,
		array	$files )

protected

Moves the extracted contents of the plugin ZIP into the target location.

Parameters

string	$sourcedir	full path to the directory the ZIP file was extracted to
mixed	$targetdir	full path to the directory where the files should be moved to
array	$files	list of extracted files

◆ rename_extracted_rootdir()

core\update\code_manager::rename_extracted_rootdir	(		$dirname,
			$rootdir,
		array	$files )

protected

Renames the root directory of the extracted ZIP package.

This internal helper method assumes that the plugin ZIP package has been extracted into a temporary empty directory so the plugin folder is the only folder there. The ZIP package is supposed to be validated so that it contains just a single root folder.

Parameters

string	$dirname	fullpath location of the extracted ZIP package
string	$rootdir	the requested name of the root directory
array	$files	list of extracted files

Return values

array eventually amended list of extracted files

◆ set_plugin_files_permissions()

core\update\code_manager::set_plugin_files_permissions	(		$targetdir,
		array	$files )

protected

Sets the permissions of extracted subdirs and files.

As a result of unzipping, the subdirs and files are created with permissions set to $CFG->directorypermissions and $CFG->filepermissions. These are too benevolent by default (777 and 666 respectively) for PHP scripts and may lead to HTTP 500 errors in some environments.

To fix this behaviour, we inherit the permissions of the plugin root directory itself.

Parameters

string	$targetdir	full path to the directory the ZIP file was extracted to
array	$files	list of extracted files

◆ unzip_plugin_file()

core\update\code_manager::unzip_plugin_file	(	$zipfilepath,
		$targetdir,
		$rootdir = '' )

Extracts the saved plugin ZIP file.

Returns the list of files found in the ZIP. The format of that list is array of (string)filerelpath => (bool|string) where the array value is either true or a string describing the problematic file.

See also: zip_packer\extract_to_pathname()

Parameters

string	$zipfilepath	full path to the saved ZIP file
string	$targetdir	full path to the directory to extract the ZIP file to
string	$rootdir	explicitly rename the root directory of the ZIP into this non-empty value

Return values

array list of extracted files as returned by zip_packer::extract_to_pathname()

◆ zip_plugin_folder()

core\update\code_manager::zip_plugin_folder	(		$folderpath,
			$targetzip )

Make an archive backup of the existing plugin folder.

Parameters

string	$folderpath	full path to the plugin folder
string	$targetzip	full path to the zip file to be created

Return values

bool	true if file created, false if not
