Detailed Description

A DatabaseBlock (unlike a SystemBlock) is stored in the database, may give rise to autoblocks and may be tracked with cookies.

Such blocks are more customizable than system blocks: they may be hardblocks, and they may be sitewide or partial.

Since: 1.34 Renamed from Block.

Member Function Documentation

◆ appliesToNamespace()

MediaWiki\Block\DatabaseBlock::appliesToNamespace ( $ns )

Checks if a block applies to a particular namespace.

Since: 1.33

Parameters

int $ns

Returns: bool

Reimplemented from MediaWiki\Block\AbstractBlock.

Definition at line 1490 of file DatabaseBlock.php.

References MediaWiki\Block\DatabaseBlock\findRestriction(), and MediaWiki\Block\AbstractBlock\isSitewide().

◆ appliesToPage()

MediaWiki\Block\DatabaseBlock::appliesToPage ( $pageId )

Checks if a block applies to a particular page.This check does not consider whether $this->isUsertalkEditAllowed returns false, as the identity of the user making the hypothetical edit isn't known here (particularly in the case of IP hardblocks, range blocks, and auto-blocks).

Since: 1.33

Parameters

int $pageId

Returns: bool

Reimplemented from MediaWiki\Block\AbstractBlock.

References MediaWiki\Block\DatabaseBlock\findRestriction(), and MediaWiki\Block\AbstractBlock\isSitewide().

◆ appliesToTitle()

MediaWiki\Block\DatabaseBlock::appliesToTitle ( Title $title )

Checks if a block applies to a particular title.This check does not consider whether $this->isUsertalkEditAllowed returns false, as the identity of the user making the hypothetical edit isn't known here (particularly in the case of IP hardblocks, range blocks, and auto-blocks).

Parameters

Title $title

Returns: bool

Reimplemented from MediaWiki\Block\AbstractBlock.

◆ chooseBlock()

static MediaWiki\Block\DatabaseBlock::chooseBlock	(	array	$blocks,
		array	$ipChain
	)

static

From a list of multiple blocks, find the most exact and strongest block.

The logic for finding the "best" block is:

Blocks that match the block's target IP are preferred over ones in a range
Hardblocks are chosen over softblocks that prevent account creation
Softblocks that prevent account creation are chosen over other softblocks
Other softblocks are chosen over autoblocks
If there are multiple exact or range blocks at the same level, the one chosen is random This should be used when $blocks were retrieved from the user's IP address and $ipChain is populated from the same IP address information.

Parameters

array	$blocks	Array of DatabaseBlock objects
array	$ipChain	List of IPs (strings). This is used to determine how "close" a block is to the server, and if a block matches exactly, or is in a range. The order is furthest from the server to nearest e.g., (Browser, proxy1, proxy2, local-cdn, ...)

Exceptions

MWException

Returns: DatabaseBlock|null The "best" block from the list

Definition at line 1258 of file DatabaseBlock.php.

References MediaWiki\Block\AbstractBlock\appliesToRight(), and MediaWiki\Block\DatabaseBlock\isHardblock().

◆ chooseMostSpecificBlock()

static MediaWiki\Block\DatabaseBlock::chooseMostSpecificBlock ( array $blocks )

staticprotected

Choose the most specific block from some combination of user, IP and IP range blocks.

Decreasing order of specificity: user > IP > narrower IP range > wider IP range. A range that encompasses one IP address is ranked equally to a singe IP.

Note that DatabaseBlock::chooseBlocks chooses blocks in a different way.

This is refactored out from DatabaseBlock::newLoad.

Parameters

DatabaseBlock[] $blocks These should not include autoblocks or ID blocks

◆ newFromTarget()

static MediaWiki\Block\DatabaseBlock::newFromTarget	(	$specificTarget,
		$vagueTarget = `null`,
		$fromMaster = `false`
	)

static

Given a target and the target's type, get an existing block object if possible.

Parameters

string \| User \| int	$specificTarget	A block target, which may be one of several types: A user to block, in which case $target will be a User An IP to block, in which case $target will be a User generated by using User::newFromName( $ip, false ) to turn off name validation An IP range, in which case $target will be a String "123.123.123.123/18" etc The ID of an existing block, in the format "#12345" (since pure numbers are valid usernames Calling this with a user, IP address or range will not select autoblocks, and will only select a block where the targets match exactly (so looking for blocks on 1.2.3.4 will not select 1.2.0.0/16 or even 1.2.3.4/32)
string \| User \| int \| null	$vagueTarget	As above, but we will search for any block which affects that target (so for an IP address, get ranges containing that IP; and also get any relevant autoblocks). Leave empty or blank to skip IP-based lookups.
bool	$fromMaster	Whether to use the DB_MASTER database

Returns: DatabaseBlock|null (null if no relevant block could be found). The target and type of the returned block will refer to the actual block which was found, which might not be the same as the target you gave if you used $vagueTarget!

		$fromMaster = `false`
	)

static

This is similar to DatabaseBlock::newFromTarget, but it returns all the relevant blocks.

Since: 1.34

Parameters

string \| User \| int \| null	$specificTarget
string \| User \| int \| null	$vagueTarget
bool	$fromMaster

Returns: DatabaseBlock[] Any relevant blocks

staticprotected

Load blocks from the database which target the specific target exactly, or which cover the vague target.

Parameters

User \| string \| null	$specificTarget
int \| null	$specificType
bool	$fromMaster
User \| string \| null	$vagueTarget	Also search for blocks affecting this target. Doesn't make any sense to use TYPE_AUTO / TYPE_ID here. Leave blank to skip IP lookups.
