Handbuch:archive-Tabelle
| ↑ Handbuch:Inhaltsübersicht | MediaWiki-Datenbank-Layout | archive-Tabelle |
Die archive-Tabelle ist der Ort, an dem MediaWiki Informationen über gelöschte Seiten speichert. Die Seiten können von einem MediaWiki-Administrator unter Verwendung der Special:Undelete-Spezialseite wiederhergestellt oder zurückgeholt werden. Ab MediaWiki 1.5 verbleibt der Inhalt der Seiten in der text-Tabelle; der Löschzeitpunkt wird in der logging-Tabelle protokolliert.
Wenn eine Seite gelöscht wird, werden alle ihre alten Revisionen aus der revision-Tabelle in die archive-Tabelle verschoben. Wenn eine Seite dann wiederhergestellt wird, werden ihre Revisionen aus der archive-Tabelle entfernt und in der revision-Tabelle neu erstellt.
The archive table is broadly related to the old table and revision table in layout; since Gerrit change 51675 it has a primary key: ar_id.
Previous to MediaWiki 1.5, content from the text table was moved here, so individual revisions had non-empty ar_text contents.
That text could have been compressed, and in those cases, it was marked by gzip on the revision's ar_flags field.
There is also not presently a record of when deletion occurred, making it hard to separate multiple delete cycles or distinguish old deletions from recent deletions of pages that haven't been edited in a long time.
Felder
ar_id
| MediaWiki Version: | ≥ 1.22 Gerrit change 51675 |
Primärschlüssel.
ar_namespace
Basic page information: contains the namespace of the deleted revision. These contain the value in page_namespace.
ar_title
Basic page information: contains the page title of the deleted page, which is the same as page_title.
ar_text
| MediaWiki Version: | ≤ 1.4 |
Before MediaWiki 1.5, old archived pages saved their text here.
Old archived pages have ar_text_id set to NULL; they do not point to an entry in the text table.
Instead, this field is the place where the text resides.
Undeleting content from an old archived page undeletes the text from this field.
| MediaWiki Versions: | 1.5 – 1.30 |
In newly deleted pages (MediaWiki 1.5 and later), the revision text remains in the text table.
Such newly deleted pages will not store text in the archive table, but will rather reference the separately existing text rows.
However, for text from pages, which have been archived in MediaWiki 1.4 and before, the ar_text field will still be used!
ar_comment
| MediaWiki Version: | ≤ 1.32 |
Basic revision information: contains the edit summary of the deleted revision, analogous to rev_comment.
(veraltet); ar_comment_id and the comment table should be used instead!
ar_comment_id
| MediaWiki Version: | ≥ 1.30 |
This is a foreign key to comment_id in the comment table.
ar_user
Basic revision information: contains the user ID of the user who made the deleted revision; it is the same as user_id and rev_user. The value for this field is 0 for anonymous edits, initializations scripts, and for some mass imports.
(veraltet in 1.31)
While Actor-Migration is being done, and depending on the configuration setting $wgActorTableSchemaMigrationStage, this field may be empty and the actor performing the edit can be stored in the ar_actor field instead.
ar_user_text
Basic revision information: This field contains the text of the editor's username, or the IP address of the editor if the deleted revision was done by an unregistered user. Vergleichbar zu rev_user_text.
(veraltet in 1.31)
While Actor-Migration is being done, and depending on the configuration setting $wgActorTableSchemaMigrationStage, this field may be empty and the actor performing the edit can be stored in the ar_actor field instead.
ar_actor
| MediaWiki Version: | ≥ 1.31 |
This is a foreign key to actor_id in the actor table.
ar_timestamp
This field contains the time at which the revision was originally saved. It is the equivalent of rev_timestamp.
ar_minor_edit
Basic revision information: Records whether the user marked the deleted revision as a Nur Kleinigkeiten wurden verändert.
If the value for this field is 1, then the edit is tagged as 'minor'; it is 0 otherwise.
This is equivalent to rev_minor_edit.
ar_flags
| MediaWiki Version: | ≤ 1.30 |
This field is similar to old_flags in the text table.
It was added in MediaWiki 1.5, but is most likely unused: For revisions archived with older versions, it is not used as it was not there at the time of their deletion; a conversion, which would have added flags for revisions, which already had been archived when the update to MediaWiki 1.5 or newer was being done, was not applied.
Texts of revisions archived with MediaWiki 1.5 or later do not use this field; they themselves stay in the text table; together with their flags staying in old_flags.
ar_rev_id
| MediaWiki Version: | ≥ 1.5 |
When revisions are deleted, their unique rev_id is stored here so it can be retained after undeletion. This is necessary to retain permalinks to given revisions after accidental delete cycles or messy operations like history merges.
rev_id will be created on undeletion for those revisions.ar_text_id
| MediaWiki Versions: | 1.5 – 1.34 |
For revisions deleted in MediaWiki 1.5 and later, this is a key to old_id within the text table; that is, it is the key to the stored text in the storage backend.
To avoid breaking the block-compression scheme and otherwise making storage changes harder, the actual text is NOT deleted from the text table; rather, the text is merely hidden by removal of the page and revision entries.
Vergleichbar zu rev_text_id.
(entfernt in 1.35) This column was replaced by content.content_address.
NULL values in this field, and their ar_text and ar_flags fields will be used to create a new text row upon undeletion.ar_deleted
| MediaWiki Version: | ≥ 1.10 |
This field is reserved for the RevDelete/Suppression (Oversight) system. Equivalent to rev_deleted.
ar_len
| MediaWiki Version: | ≥ 1.10 |
This field contains the length of the deleted revision, in bytes. Analogous to rev_len.
ar_page_id
| MediaWiki Version: | ≥ 1.11 |
Reference to the page_id of the deleted page this archive row was created from. Useful for sysadmin fixing of large pages merged together in the archives, or for cleanly undeleting a page at its original ID number if possible. Vergleichbar zu rev_page. Will be NULL for pages deleted prior to 1.11.
Note that because of MediaWiki supporting partial undeletion and history split/merge, there is no guarantee ar_page_id matches the page ID it's going to be undeleted to.
ar_parent_id
| MediaWiki Version: | ≥ 1.13 |
The revision id of the previous revision to the page. Populated from rev_parent_id. Will be null for revisions deleted prior to 1.13. First edits to newly created articles (and therefore the creation of the article) can be identified by the value of this field being 0.
ar_sha1
| MediaWiki Version: | ≥ 1.19 |
The SHA-1 text content hash in base-36. Populated from rev_sha1.
ar_content_format
| MediaWiki Versions: | 1.21 – 1.34 |
Content format for the archived revision, which is NULL by default and only stored if it differs from the page's default.
(entfernt in 1.35) This column was removed. The ContentHandler class is able to automatically detect the content format, and replaces this column.
ar_content_model
| MediaWiki Versions: | 1.21 – 1.34 |
Content model for the archived revision, which is NULL by default and only stored if it differs from the page's default, as determined by ContentHandler::getDefaultModelFor( $title ).
(entfernt in 1.35) This column was replaced by content.content_model, which references content_models.model_id.
