|
* Upgrade the core of WordPress.
|
|
*
|
|
* This will create a .maintenance file at the base of the WordPress directory
|
|
* to ensure that people can not access the web site, when the files are being
|
|
* copied to their locations.
|
|
*
|
|
* The files in the {@link $_old_files} list will be removed and the new files
|
|
* copied from the zip file after the database is upgraded.
|
|
*
|
|
* The steps for the upgrader for after the new release is downloaded and
|
|
* unzipped is:
|
|
* 1. Test unzipped location for select files to ensure that unzipped worked.
|
|
* 2. Create the .maintenance file in current WordPress base.
|
|
* 3. Copy new WordPress directory over old WordPress files.
|
|
* 4. Upgrade WordPress to new version.
|
|
* 5. Delete new WordPress directory path.
|
|
* 6. Delete .maintenance file.
|
|
* 7. Remove old files.
|
|
* 8. Delete 'update_core' option.
|
|
*
|
|
* There are several areas of failure. For instance if PHP times out before step
|
|
* 6, then you will not be able to access any portion of your site. Also, since
|
|
* the upgrade will not continue where it left off, you will not be able to
|
|
* automatically remove old files and remove the 'update_core' option. This
|
|
* isn't that bad.
|
|
*
|
|
* If the copy of the new WordPress over the old fails, then the worse is that
|
|
* the new WordPress directory will remain.
|
|
*
|
|
* If it is assumed that every file will be copied over, including plugins and
|
|
* themes, then if you edit the default theme, you should rename it, so that
|
|
* your changes remain.
|
|
*
|
|
* @since 2.7.0
