40 | =head1 DESCRIPTION |
41 | |
42 | Handles the installing and uninstalling of perl modules, scripts, man |
43 | pages, etc... |
44 | |
45 | Both install() and uninstall() are specific to the way |
46 | ExtUtils::MakeMaker handles the installation and deinstallation of |
47 | perl modules. They are not designed as general purpose tools. |
48 | |
3a465856 |
49 | On some operating systems such as Win32 installation may not be possible |
50 | until after a reboot has occured. This can have varying consequences: |
51 | removing an old DLL does not impact programs using the new one, but if |
52 | a new DLL cannot be installed properly until reboot then anything |
53 | depending on it must wait. The package variable |
54 | |
55 | $ExtUtils::Install::MUST_REBOOT |
56 | |
57 | is used to store this status. |
58 | |
59 | If this variable is true then such an operation has occured and |
60 | anything depending on this module cannot proceed until a reboot |
61 | has occured. |
62 | |
63 | If this value is defined but false then such an operation has |
64 | ocurred, but should not impact later operations. |

205 | |
206 | OS-Specific, Win32/Cygwin |
207 | |
208 | Tries to get a file out of the way by unlinking it or renaming it. On |
209 | some OS'es (Win32 based) DLL files can end up locked such that they can |
210 | be renamed but not deleted. Likewise sometimes a file can be locked such |
211 | that it cant even be renamed or changed except at reboot. To handle |
212 | these cases this routine finds a tempfile name that it can either rename |
213 | the file out of the way or use as a proxy for the install so that the |
214 | rename can happen later (at reboot). |
215 | |
216 | $file : the file to remove. |
217 | $tryhard : should advanced tricks be used for deletion |
218 | $installing : we are not merely deleting but we want to overwrite |
219 | |
220 | When $tryhard is not true if the unlink fails its fatal. When $tryhard |
221 | is true then the file is attempted to be renamed. The renamed file is |
222 | then scheduled for deletion. If the rename fails then $installing |
223 | governs what happens. If it is false the failure is fatal. If it is true |
224 | then an attempt is made to schedule installation at boot using a |
225 | temporary file to hold the new file. If this fails then a fatal error is |
226 | thrown, if it succeeds it returns the temporary file name (which will be |
227 | a derivative of the original in the same directory) so that the caller can |
228 | use it to install under. In all other cases of success returns $file. |
229 | On failure throws a fatal error. |

284 | |
285 | Copies each directory tree of %from_to to its corresponding value |
286 | preserving timestamps and permissions. |
287 | |
288 | There are two keys with a special meaning in the hash: "read" and |
289 | "write". These contain packlist files. After the copying is done, |
290 | install() will write the list of target files to $from_to{write}. If |
291 | $from_to{read} is given the contents of this file will be merged into |
292 | the written file. The read and the written file may be identical, but |
293 | on AFS it is quite likely that people are installing to a different |
294 | directory than the one where the files later appear. |
295 | |
296 | If $verbose is true, will print out each file removed. Default is |
3a465856 |
297 | false. This is "make install VERBINST=1". $verbose values going |
298 | up to 5 show increasingly more diagnostics output. |
479d2113 |
299 | |
300 | If $dont_execute is true it will only print what it was going to do |
301 | without actually doing it. Default is false. |
302 | |
1df8d179 |
303 | If $uninstall_shadows is true any differing versions throughout @INC |
304 | will be uninstalled. This is "make install UNINST=1" |
305 | |
3a465856 |
306 | As of 1.37_02 install() supports the use of a list of patterns to filter |
307 | out files that shouldn't be installed. If $skip is omitted or undefined |
308 | then install will try to read the list from INSTALL.SKIP in the CWD. |
309 | This file is a list of regular expressions and is just like the |
310 | MANIFEST.SKIP file used by L<ExtUtils::Manifest>. |
311 | |
312 | A default site INSTALL.SKIP may be provided by setting then environment |
313 | variable EU_INSTALL_SITE_SKIPFILE, this will only be used when there |
314 | isn't a distribution specific INSTALL.SKIP. If the environment variable |
315 | EU_INSTALL_IGNORE_SKIP is true then no install file filtering will be |
316 | performed. |
317 | |
318 | If $skip is undefined then the skip file will be autodetected and used if it |
319 | is found. If $skip is a reference to an array then it is assumed |
320 | the array contains the list of patterns, if $skip is a true non reference it is |
321 | assumed to be the filename holding the list of patterns, any other value of |
322 | $skip is taken to mean that no install filtering should occur. |
