If you are upgrading to MediaWiki 1. More details on installing and updating external libraries can be found in the Git download documentation. Using patch A small patch file is usually made available for a minor version upgrade. Manually download and extract the patch file from the dumps site or follow the directions with wget below. Patches are incremental, you can not skip a version.
Download the patch file and gunzip it. Use patch -p1 --dry-run to check what will be changed e. Files remaining that may cause errors If you unpacked over the old installation directory, some old files can cause problems with the new version.
Deleting, or renaming, the StartProfiler. The StartProfiler. After upgrading to this version, you should ensure that the old files Chick. MediaWiki will log warnings if any of them are still found to help you remember. You will also need to adjust any custom skins to follow a similar convention.
See Manual:Skin autodiscovery for details.
After upgrading to this version, you should ensure that the old files CologneBlue. Upgrade extensions Certain extensions have been updated in order to work with the new version of MediaWiki.
Be sure to upgrade to the latest versions of such extensions. You might need to perform manual updates to custom extensions. Different tarballs include some subsets of extensions and have versioning which helps you upgrade choosing the right one for your MediaWiki core release. Extension Distributor works well for most people who want a snapshot of extensions that will work with their supported versions of MediaWiki.
If you want a lot of extensions then downloading from Git is probably best.
If you don't have Git but you want to upgrade a lot of extensions, you might consider using mwExtUpgrader. Adapt your LocalSettings. This is what you need to add to LocalSettings.
Warning The automatic rollback only happens if you initiate the transaction via PDO::beginTransaction. If you manually issue a query that begins a transaction PDO has no way of knowing about it and thus cannot roll it back if something bad happens. Example 5. Executing a batch in a transaction In the following sample, let's assume that we are creating a set of entries for a new employee, who has been assigned an ID number of In addition to entering the basic data for that person, we also need to record their salary.
It's pretty simple to make two separate updates, but by enclosing them within the PDO::beginTransaction and PDO::commit calls, we are guaranteeing that no one else will be able to see those changes until they are complete.
If something goes wrong, the catch block rolls back all changes made since the transaction was started, and then prints out an error message.
Prepared statements and stored procedures Many of the more mature databases support the concept of prepared statements. What are they? You can think of them as a kind of compiled template for the SQL that you want to run, that can be customized using variable parameters. Prepared statements offer two major benefits: The query only needs to be parsed or prepared once, but can be executed multiple times with the same or different parameters.
When the query is prepared, the database will analyze, compile and optimize it's plan for executing the query. For complex queries this process can take up enough time that it will noticeably slow down your application if you need to repeat the same query many times with different parameters. In short, prepared statements use fewer resources and thus run faster.
The parameters to prepared statements don't need to be quoted; the driver handles it for you. If your application exclusively uses prepared statements, you can be sure that no SQL injection will occur. However, if you're still building up other parts of the query based on untrusted input, you're still at risk. Prepared statements are so useful that they are the only feature that PDO will emulate for drivers that don't support them.
This ensures that you will be able to use the same data access paradigm regardless of the capabilities of the database. Example 6. Repeated inserts using prepared statements This example performs an INSERT query by substituting a name and a value for the named placeholders.
However, if you feel the urge to do so, this is the place to make your changes. Make sure you know what you are doing.
This setting is similar to wgScript as you can configure the exact name of the script. As mentioned above, this is probably not a good idea unless you really know what you are doing.
If you make a mistake here, internal links will show up incorrectly while you still may be able to access the main page by specifying the correct URL manually. Upload location The upload directory is the place where files uploaded by the users are stored.
Next, try to find the line that looks like this in LocalSettings. Then, modify that line to point to your logo. The logo must be web accessible. The value of this variable is passed to the web browser, which uses it to fetch the logo. This is not recommended, as the customized logo would be overwritten on upgrade. This e-mail address is used to send internal bug reports to. As an administrator, you want to include your e-mail address here.
Choose an address people can reply to in case of trouble or confusion. In most cases this will be just "localhost" as the database is run on the same system, but for distributed installations, you need to fill in the fully qualified domain name of the computer running the database.
Make sure you have stated the correct database name here and use different database names for different wiki installations on the same database server. Make sure the specified user has the proper access rights to be able to manipulate the wiki's table on the database server.
In this array, custom permission levels can be created, and permission levels for the different user groups can be set. See Help:User rights for more information about the different permissions and user groups available. Force capital links By default, no page name can start with a lowercase Roman letter : in an attempt to do so the first letter is converted to uppercase; if a link target, included page, image or category is specified with a name starting with a lowercase letter, the actual target etc.
Alternatively page names can start with a lowercase letter, in addition to the possibilities of starting with a capital, a digit, etc. Setting it to false allows lowercase characters, true chooses the default behavior. Enabling subpages In LocalSettings.
