Invalid Data Value Log

Invalid data value logs are item forms of the primary log block with damage values outside of the usual range which logs can usually be obtained in.

Obtaining

Without the use of commands, invalid data value logs are unobtainable in the last versions in which they existed without inheriting them from a prior version in which they were obtainable.

Breaking

Prior to 12w30d (the first version in which logs could be placed sideways), if a log block with an invalid data value exists inside of the world, it can be broken to obtain a log item of that data value. Such blocks can be obtained through block transmutation, with liquid transmutation being the most versatile.

In 12w30d and 12w30e, a tool enchanted with Silk Touch can be used to obtain an invalid data value log item if a sideways log is broken with it.

Usage

Placement

From 12w30d to 14w21b, invalid data value log items will place the log corresponding to their species. The directionality of the item is ignored; the item will be placed as if it were a normal log item. This also means that "wood" items will place a log rather than wood.

Attempting to place any log, regardless of data value, will immediately crash the game in 14w25a.

From 14w25b to 17w46a, the pre-14w25a behaviour can be seen again.

Conversion to future versions

In 1.13 (17w47a) onwards, distinguishing between block and item variants using metadata and damage was formally abolished. As a result of this, existing items would be converted over to the new ID system automatically. Invalid data value logs behave anomalously in that instead of converting to their respective parent species, they all convert to oak logs instead. In addition, items with data values 12 to 15, which represent wood rather than logs, still become logs.

History

Java Edition Indev
0.31		20100131			Durability has been introduced. It can be assigned to log items via an inventory editor, but is functionally meaningless in this case.
Java Edition Beta
1.2					Log items with a nonzero value set for damage now process this as a variant form of the item, rather than literal damage, resulting in the item forms now appearing distinct. The durability bar has also been removed from logs with higher damage values.
1.7					Block transmutation is now possible, allowing for invalid data value logs to be obtained.
Java Edition
1.3.1		?			Logs now have different tooltips for each species. All invalid data value item forms of logs are named "Oak Wood", regardless of species.
		12w30d			The block forms of invalid data value logs are now all occupied, with 4-11 representing sideways logs and 12-15 representing what would later become wood. Breaking any of these normally will now yield normal log items, however Silk Touch can still be used to access the items.
		1.3			Silk Touch can no longer be used to obtain invalid data value logs as items, making them unobtainable in survival from this point onwards.
1.8		14w17a			Invalid data value logs with damage value 4 are now named "Acacia Wood", and damage value 5 is now named "Dark Oak Wood", despite the real blocks these are named after using a completely separate ID.
		14w25a			With the introduction of data-driven item models, any item with a data value outside of what is accepted by the game has no model to point to, resulting in use of the missing item model.
		14w30a			Invalid data value logs, alongside other invalid data value items, now appear the size of a full block when held in third person or by another player or mob.
1.9		15w31a			The missing model's inventory appearance has changed, resulting in the appearance of invalid data value logs also changing.
					The items also appear the size of a full block when held in first person and when dropped on the ground, and also appear larger than before in an item frame.
1.13		17w43a			The missing texture has changed, resulting in the appearance of invalid data value logs also changing.
		17w47a			Numeric IDs for blocks and items have been completely removed from the game, with different species of logs being given their own string IDs. As a result, invalid data value logs have been "removed" as any such item now converts cleanly into oak logs.
Pocket Edition Alpha
v0.8.0		build 1			With the introduction of rotatable logs, damage values 4–6 and 8–10 were legitimately obtainable by mining their respective block forms.
		build 3			Mining invalid data value logs now yields normal log items.
Legacy Console Edition
?					Invalid data value log items can be obtained through block transmutation.
?					Invalid data value logs in item form now appear "rotated" like in Java Edition between 12w30d and 14w08a. In Xbox 360 Edition, this is the appearance that is adopted in placed form; PlayStation 3 Edition instead has glitchy textures for the placed variants.
TU14		1.04			Sideways log placement has been implemented fully, making invalid data value log items unobtainable.

Inventory appearances

From version		Damage value												Notes
		4	5	6	7	8	9	10	11	12	13	14	15
0.31	20100131													Durability introduced. Currently meaningless for logs.
	20100201-2227													All 3D items now appear slightly darker on the left.
														All 3D items now appear much brighter.
Minecraft Infdev	20100611													All 3D items now appear slightly darker.
Alpha v1.0.1														All 3D items now appear very slightly darker.
Beta 1.2														Values for damage on logs are now processed as variants. The durability bar has been removed.
Beta 1.6	Test Build 3													All 3D items now appear much brighter and are rotated 90 degrees clockwise from their previous positions.
Beta 1.8	Pre-release													All 3D items now appear even brighter than previously, with almost no shading.
1.0.0	RC2													All 3D items are now shaded more reasonably.
1.3.1	12w22a													All 3D items in the inventory have been rotated 90 degrees anti-clockwise.
	12w30d													Log items now represent their rotation. The individual textures do not appear rotated.
1.4.2	12w34a													Items appeared slightly darker in the player's inventory than in chests prior to this version.
1.7.2	1.7													Birch, spruce and jungle logs have now been given unique inside textures.
1.8	14w10a													Logs appear properly rotated, however the lighting is also rotated. 12-15 are now 2D.
	14w10b													12-15 now appear 3D again.
	14w25a													Model no longer exists
1.9	15w31a													The missing model is no longer rotated or downscaled.
1.13	17w43a													The missing texture has changed.

Issues

Invalid data value logs are an issue, and due to their removal, can be considered already fixed.
