Manual:Archive table/fr

La table Archive est un endroit où MediaWiki enregistre les informations concernant les pages supprimées. Les pages peuvent être restaurées, ou non supprimées, par un Administrateur MediaWiki en utilisant la page spéciale Special:Undelete. A partir de MediaWiki 1.5, le contenu des pages reste dans la table ; l'heure de suppression est tracée dans la table.

Quand une page est supprimée, toutes ses anciennes révisions sont transférées de la table vers la table archive. Lorsqu'une page est ensuite restaurée, ses révisions sont supprimées de la table archive, et recréées dans la table des révisions.

La table table est largement liée à la table et la table  pour l'affichage; depuis  elle possède une clé primaire: ar_id.

Avant MediaWiki 1.5, le contenu de la table de texte était déplacé ici, et donc les révisions individuelles avaient des contenus ar_text non vides. Ce texte pouvait être compressé, et dans ce cas, il était marqué par  dans le champ ar_flags de la révision. Il y a aussi et pas actuellement, un enregistrement du moment où la supression a eu lieu, rendant difficile la séparation de multiples cycles de supression ou pour distinguer les anciennes suppressions des pages qui n'ont pas été modifiées depuis longtemps, des nouvelles supressions. (Les propositions pour enregistrer ces données dans ou  furent rejetées).

ar_id
Clé primaire.

ar_namespace
Page d'informations de base : contient l'espace de noms de la révision supprimée. These contain the value in.

ar_title
Basic page information: contains the page title of the deleted page, which is the same as.

ar_text
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. Restoring content from an old archived page restores the text from this field.

Still used! In newly deleted pages (MediaWiki 1.5 and later), the revision text remains in the 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 However, for text from pages, which have been archived in MediaWiki 1.4 and before, the ar_text field will still be used!

This field remains for backward compatibility.

ar_comment
Basic revision information: contains the edit summary of the deleted revision, analogous to.


 * ar_comment_id and the comment table should be used instead!

ar_comment_id
This is a foreign key to in the  table.

ar_user
Basic revision information: contains the user ID of the user who made the deleted revision; it is the same as and. The value for this field is 0 for anonymous edits, initializations scripts, and for some mass imports.

While is being done, and depending on the configuration setting, 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. Comparable to.

While is being done, and depending on the configuration setting, this field may be empty and the actor performing the edit can be stored in the ar_actor field instead.

ar_timestamp
This field contains the time at which the revision was originally saved. It is the equivalent of.

ar_minor_edit
Basic revision information: Records whether the user marked the deleted revision as a. If the value for this field is 1, then the edit is tagged as 'minor'; it is 0 otherwise. This is equivalent to.

ar_flags
This field is similar to in the  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.

ar_rev_id
When revisions are deleted, their unique 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.

ar_text_id
For revisions deleted in MediaWiki 1.5 and later, this is a key to within the  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. Comparable to.

ar_deleted
This field is reserved for the RevDelete/Suppression (Oversight) system. Equivalent à.

ar_len
This field contains the length of the deleted revision, in bytes. Analogue à.

ar_page_id
Référence à. Useful for sysadmin fixing of large pages merged together in the archives, or for cleanly restoring a page at its original ID number if possible. Comparable à. Sera NULL pour les pages supprimées avant la version 1.11.

ar_parent_id
The revision id of the previous revision to the page. Rempli à partir de. 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
La valeur de hachage du contenu du texte du SHA-1 en base 36. Rempli à partir de.

ar_content_format
Content format for the archived revision, which is NULL by default and only stored if it differs from the page's default.

ar_content_model
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 ).
