- =head1 NAME
-
- ExtUtils::Install - install files from here to there
-
- =head1 SYNOPSIS
-
- use ExtUtils::Install;
-
- install({ 'blib/lib' => 'some/install/dir' } );
-
- uninstall($packlist);
-
- pm_to_blib({ 'lib/Foo/Bar.pm' => 'blib/lib/Foo/Bar.pm' });
-
- =head1 DESCRIPTION
-
- Handles the installing and uninstalling of perl modules, scripts, man
- pages, etc...
-
- Both install() and uninstall() are specific to the way
- ExtUtils::MakeMaker handles the installation and deinstallation of
- perl modules. They are not designed as general purpose tools.
-
- On some operating systems such as Win32 installation may not be possible
- until after a reboot has occured. This can have varying consequences:
- removing an old DLL does not impact programs using the new one, but if
- a new DLL cannot be installed properly until reboot then anything
- depending on it must wait. The package variable
-
- $ExtUtils::Install::MUST_REBOOT
-
- is used to store this status.
-
- If this variable is true then such an operation has occured and
- anything depending on this module cannot proceed until a reboot
- has occured.
-
- If this value is defined but false then such an operation has
- ocurred, but should not impact later operations.

- $file should be a filespec of an existing file

- it will be replaced.

- Sets $MUST_REBOOT to 0 to indicate a deletion operation has occured
- and sets it to 1 to indicate that a move operation has been requested.
-
- returns 1 on success, on failure if $moan is false errors are fatal.
- If $moan is true then returns 0 on error and warns instead of dies.

-
- =item _unlink_or_rename( $file, $tryhard, $installing )
-
- OS-Specific, Win32/Cygwin
-
- Tries to get a file out of the way by unlinking it or renaming it. On
- some OS'es (Win32 based) DLL files can end up locked such that they can
- be renamed but not deleted. Likewise sometimes a file can be locked such
- that it cant even be renamed or changed except at reboot. To handle
- these cases this routine finds a tempfile name that it can either rename
- the file out of the way or use as a proxy for the install so that the
- rename can happen later (at reboot).
-
- $file : the file to remove.
- $tryhard : should advanced tricks be used for deletion
- $installing : we are not merely deleting but we want to overwrite
-
- When $tryhard is not true if the unlink fails its fatal. When $tryhard
- is true then the file is attempted to be renamed. The renamed file is
- then scheduled for deletion. If the rename fails then $installing
- governs what happens. If it is false the failure is fatal. If it is true
- then an attempt is made to schedule installation at boot using a
- temporary file to hold the new file. If this fails then a fatal error is
- thrown, if it succeeds it returns the temporary file name (which will be
- a derivative of the original in the same directory) so that the caller can
- use it to install under. In all other cases of success returns $file.
- On failure throws a fatal error.

-
- =item B<install>
-
- install(\%from_to);
- install(\%from_to, $verbose, $dont_execute, $uninstall_shadows, $skip);
-
- Copies each directory tree of %from_to to its corresponding value
- preserving timestamps and permissions.
-
- There are two keys with a special meaning in the hash: "read" and
- "write". These contain packlist files. After the copying is done,
- install() will write the list of target files to $from_to{write}. If
- $from_to{read} is given the contents of this file will be merged into
- the written file. The read and the written file may be identical, but
- on AFS it is quite likely that people are installing to a different
- directory than the one where the files later appear.
-
- If $verbose is true, will print out each file removed. Default is
- false. This is "make install VERBINST=1". $verbose values going
- up to 5 show increasingly more diagnostics output.
-
- If $dont_execute is true it will only print what it was going to do
- without actually doing it. Default is false.
-
- If $uninstall_shadows is true any differing versions throughout @INC
- will be uninstalled. This is "make install UNINST=1"
-
- As of 1.37_02 install() supports the use of a list of patterns to filter
- out files that shouldn't be installed. If $skip is omitted or undefined
- then install will try to read the list from INSTALL.SKIP in the CWD.
- This file is a list of regular expressions and is just like the
- MANIFEST.SKIP file used by L<ExtUtils::Manifest>.
-
- A default site INSTALL.SKIP may be provided by setting then environment
- variable EU_INSTALL_SITE_SKIPFILE, this will only be used when there
- isn't a distribution specific INSTALL.SKIP. If the environment variable
- EU_INSTALL_IGNORE_SKIP is true then no install file filtering will be
- performed.
-
- If $skip is undefined then the skip file will be autodetected and used if it
- is found. If $skip is a reference to an array then it is assumed
- the array contains the list of patterns, if $skip is a true non reference it is
- assumed to be the filename holding the list of patterns, any other value of
- $skip is taken to mean that no install filtering should occur.

- install_default();
- install_default($fullext);
-
- Calls install() with arguments to copy a module from blib/ to the
- default site installation location.
-
- $fullext is the name of the module converted to a directory
- (ie. Foo::Bar would be Foo/Bar). If $fullext is not specified, it
- will attempt to read it from @ARGV.
-
- This is primarily useful for install scripts.
-
- B<NOTE> This function is not really useful because of the hard-coded
- install location with no way to control site vs core vs vendor
- directories and the strange way in which the module name is given.
- Consider its use discouraged.
