Manual talk:Upgrading/Archive 2

This has just been changed back into a redirect with the reason "less work, more up-to-date", however I think this page had a useful purpose, which is more than a simple 'upgrading to the latest version' page can offer.

Is there any objection to re-instating the page as it was?

 * I would prefer to see the below content integrated into the main Manual:Upgrading page. I tend to agree that multiple pages with overlapping content or goals should be merged and formatted in a more reader-friendly way perhaps if the content is just overwhelming as is.

INDEX command denied to user
i am trying to upgrade a number of wikis [1.11.0 and 1.11.2] to 1.15.1. on virtually all the upgrades i am getting an error:

MySQL returned error "1142: INDEX command denied to user '$WIKIadm'@'localhost' for table 'pagelinks' (localhost)"

the problem being that on each of them, when i go into mysql and issue a show grants, all of those users have INDEX:

mysql> show grants for '$WIKIadm'@'localhost'; +---+ | Grants for $WIKIadm@localhost                                                                                | +---+ | GRANT USAGE ON *.* TO '$WIKIadm'@'localhost' IDENTIFIED BY PASSWORD '$PASSWORD'                              | | GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, ALTER, LOCK TABLES ON `$WIKI`.* TO '$WIKIadm'@'localhost'      | +---+ 2 rows in set (0.01 sec)

so what gives?

You need to set grant for index(It is not in the list, use all when setting, if this is confusing set it $wgDBadminuser='root' and use root user.

Where do you come from?
I realy miss the clear description whether or not you may upgrade from earlier versions of MW than the predecessor of the announced version. To give an example: I was asked by a customer: Can I upgrade from version 1.9 directly to the newest MW version? and being not well educated in MW my self, I had no proper reaction to make.

Are there restrictions? What restrictions may exist when you have a lot of Extensions installed? OK I accept that you have to find out for each extentention whether or not it supports the version to be installed. But nevertheless a warining for that should be in place here.

Again, may experience on this subject is too low to make changes myslef so please make soma improvements on this subject in the page if you can. JanEnEm 06:46, 25 April 2010 (UTC)

Applying a patch
The demarcation between MW specific and OS/other issues is not always obvious. Applying a patch is one of them.

I spent the best part of a day hunting for information about how to apply a MW patch to no avail. Since it is central to the quick application of MW security fixes I think it would be useful to have at least a 'patch file application basics' somewhere on the MW site. Anyway here's what I eventually came up with - posted here in hopes it may help somebody:

Applying a MW patch file requires the Unix 'Patch' utility to be available (or equivalents on other OS's). Detailed usage/syntax instructions are here but the following worked for me on Centos 5.4:


 * 1) Extract the tar.gz to the wiki root directory.
 * 2) Execute the command "patch -i  PATCHFILENAME -p 1

The '-p 1' parameter strips the first part of the pathname from each of the files to be patched. This is necessary because the MW patch files specify each file to be patched from the domain root using the full release specification name as the first directory down from the domain root.

Once you've got it, the whole process takes just a few minutes. Having gone through about 10 installs/upgrades since starting with MW about 9 months ago, I'm fairly proficient at it. However, for bona-fide patches - especially important security ones - the patch process is well worth becoming proficient with.

Upgrading from 1.17alpha to a newer version of 1.17alpha
Are there any difficulties that will occur when upgrading from 1.17alpha to a newer version of 1.17alpha? I have a wiki that I want to keep always on the cutting edge (or close to it) of MediaWiki core development, but I guess this will require frequent upgrades and running of update.php.

Method not implemented error
I've hit an intermittent problem that I cannot track down. It goes like this:

Occasionally when editing an existing, or authoring a new article I get the following error when either previewing or saving changes: Method not implemented. Post to /w/index.php not supported I use pretty urls which may or may not be relevant. The problem has only appeared since upgrading from 1.16beta3 to 1.16.0. (Although it is just possible that an upgrade to both php and mysql a few days earlier is implicated). I also thought I'd got the trigger when I found that an article exhibiting this problem contained an unclosed 'blockquote' tag and closing it got rid of the error on that article; but it has since happened several times since with no such obvious trigger present.

Upgrade - How?
Dear MediaWiki readers.

I'm using MediaWiki on a free webhosting service, and decides to upgrade from 1.15.0 to 1.16.0, but runs into some troubles. According to the manual, I shall locate the update script, and open it. Yeah okay, I find a update.php inside Maintenance, but I can't open it because a damn htaccess file. Well, okay, when that failed, I just for fun checked the directory config but nothing useful there.

I have to disappoint You: I do not have server access, nor SSH access, I only have FTP and HTTP access to my website, so how the h. can I upgrade, without losing all my data?

1. GNU diff3 is not found, even though these are specified in LocalSettings.php:

2. Upgrade script says Success when it finishes updating the database. However, I noticed errors that one of the tables was nonexistent. These tables cause errors unless you manually add them to your database. You can install a new database (blank) and export them and then import them into your existing database, or you can manually add these table to your database. I hope I don't have problems because I'm using MyISAM with my other database tables and these are set to InnoDB (and they have multiple keys, so I think it's required to use InnoDB):

Problem
I tried to upgrade my MediaWiki from version 1.15 to 1.17 using the commandline method by running update.php in the /maintenance directory. Although the first few schema updates went ok (all sequence rename operations), the log_log_id_seq to loggin_log_id_seq and pr_id_val to page_restrictions_pr_id_seq rename operations failed because in a previous operation they had been created. Apparently, Postgres behaves different from MySQL in this regard failing whith a serious enough error to halt the update script.

Temporary fix
Fixed this by manually duplicating both sequences with their new names, starting at wherever the 'old' sequence was at (peeked at the create script that pgAdmin III showed me), and updated the id columns of the logging and page_restrictions tables to point respectively to the newly created sequences in each default function (showing nextval('...'::regclass)</tt>). After that I commented both the # new sequences</tt> lines: //array( 'addSequence', 'logging_log_id_seq'         ), //array( 'addSequence', 'page_restrictions_pr_id_seq' ),

as well as the two corresponding # renamed sequences</tt> lines: //array( 'renameSequence', 'log_log_id_seq',     'logging_log_id_seq'          ), //array( 'renameSequence', 'pr_id_val',          'page_restrictions_pr_id_seq' ),

in /includes/installer/PostgresInstaller.php</tt>. Found this after backtracing the error message and the objects involved from update.php to /Maintenance.php looking for getCoreUpdateList</tt> in relation to Postgres.

Alternative temporary fix
If update script hasn't been executed yet, simply remove or comment out lines 25 and 26 from //array( 'addSequence', 'logging_log_id_seq'         ), //array( 'addSequence', 'page_restrictions_pr_id_seq' ),

If the update script has already been executed, restore your backup or do what is suggested above (untested).


 * If the update script has already been executed, just delete those new sequence: DROP SEQUENCE logging_log_id_seq; DROP SEQUENCE page_restrictions_pr_id_seq; and try this alternative temporary fix again. 109.60.112.140 07:47, 9 January 2012 (UTC)

Suggestion
Working with Postgres (as I have experienced with lots of extensions as well) differs more than most programmers expect. It might be worth the effort to abstract these differences through a more generic database layer for the whole MediaWiki framework. But that, of course, should be discussed elsewhere on the fora or this site :-)

php update.php returns nothing and system not upgraded.
I tried to follow all the upgrade instructions but when I got to the run php update.php from the command-line, it returns very quickly with no feedback whatsoever. And it obviously did nothing to make the upgrade work because every page I try from the new wiki is completely blank.

Explaination: This was due to errors loading some of php files in the added extensions.

Problems upgrading from old version
I've upgraded before without problems, but this time I realized one of my sites had not been upgraded since version 1.11, and was long overdue. I uploaded the new files and ran the upgrade routine, but like one of the comments above noted, the new tables were not created. So I've been manually creating and modifying them, and finally got the wiki to run. Unfortunately, there is still at least one error I can't seem to figure out how to get rid of. I am getting the following error:


 * A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was: (SQL query hidden)  from within function "IndexPager::reallyDoQuery (LogPager)". Database returned error "1176: Key 'log_user_type_time' doesn't exist in table 'logging' (xxxxx.xxxxx.net)".

I ran rebuildall.php with the hope that it would create whatever was missing (an index?). I don't see any field called log_user_type_time in the table 'logging', so I assume this is a missing index. I can't find any documentation about log_user_type_time. Can anyone point me in the right direction? Thanks.

Also, since I don't seem to be alone in having the problem that tables are not being updated after upgrading (never had this problem with previous upgrades) I'm wondering if this is a bug. -- Sam 10:43, 18 January 2012 (UTC)


 * You may have added some or even all columns to your database, but the key log_user_type_time is still missing. Running update.php won't fix this, as it only checks for the column "log_user_text" and if that one is there, the patch, which should among other things add this key, is not applied. You can execute
 * ALTER TABLE logging DROP COLUMN log_user_text;
 * Then rerun update.php which should now pick that full patch. --88.130.80.237 12:19, 26 March 2012 (UTC)

Any plans to automate Upgrading Mediawiki?
There are lots of people I bet that use mediawiki that are not tech savvy enough to perform an upgrade. Are there any plans to automate this process in the future? Would be nice.

update.php
Could someone please explain how to run the update.php file using ssh. I am on a local MAMP server and I have been looking around for two hours online for a simple explanation as to how to navigate and run commands using terminal. "CD" doesn't seem to work. Someone should make a wiki with that info. Thank you! 24.130.249.87 21:51, 26 February 2012 (UTC)


 * What exactly happens, if you try using cd? We won't be able to fix a "does not seem to work".
 * Use
 * cd wiki/maintenance
 * or cd ../path/to/the/foldername-with-my-wiki-in-it/maintenance or something like that to bring you to the maintenance folder. Then run
 * php update.php
 * This is the way to go. If it's a local machine where you have direct access to the files (e.g. using a file commander or so) you could also navigate to the maintenance folder there and run the file update.php by double clicking on it (make sure it is associated to the PHP executable and Apache and MySQL are running). --88.130.80.237 12:11, 26 March 2012 (UTC)

Fatal error upgrading from 1.17.0 to 1.18.2: Call to a member function getDbType on a non-object in maintenance/doMaintenance.php on line 91

 * You should extract the 1.18.2 source code into a new folder. Then move your LocalSettings.php and the folders images/, extensions/ and skins/ there as well and try from there.
