Zero-length array allocation inspection (idea) #504

RusTit · 2018-04-05T13:10:48Z

Text:
Reports on allocations of arrays with known lengths of zero. Since array lengths in Java are non-modifiable, it is almost always possible to share zero-length arrays, rather than repeatedly allocating new zero-length arrays. Such sharing may provide useful optimizations in program runtime or footprint. Note that this inspection does not report zero-length arrays allocated as static final fields, as it is assumed that those arrays are being used to implement array sharing.
And also I removed two methods. They are the same as those of the parent class.

…tedOreIngredient.java

…e as in parent class.

@Nedelosk please review.

No problem, but it can take some time.

Any idea what the significance of this number is?
I thought it might be a power of 2 minus 1, but the nearest power of 2 is 2^14 (16384) which is also a weird number.

No idea, I was trying to find this value (binnie, forestry, forge) but no successed

Max seems to be OreDictionary.WILDCARD_VALUE at 32767 so this doesn't even have the right number of bits.

Method names should start with a lowercase letter.

Actually I think this should just be created statically instead of using a singleton getter, since it is not very expensive to create and does not pull in lots of other classes.

private static Pattern PATTERN = Pattern.compile("_", Pattern.LITERAL);

In this case it is not. At first version I do like you describe. But after mc run, it crushed with NullPointException in

@Override public String toString() { return GetPattern().matcher(super.toString().toLowerCase(Locale.ENGLISH)).replaceAll(StringUtils.EMPTY); }

Where is some issue with object creating (initial). At moment then toString invoked PATTERN will be null.

Hm enums are weird, I guess they are being constructed before static. This is fine then.

One nice use of final is for cases like this. You can make final Object texture; and the static analyzer will complain "variable 'texture' might not have been initialized" if there is a case where it is not set.

I introduced the proposed changes, but it seems that the static analyzer worked correctly without them.

Please do not add more commits on to this PR, it needs to be reviewed and merged but that gets harder with more commits.
You can create a new PR for more changes.

RusTit · 2018-04-16T01:34:47Z

Ok, but to make clear, where is still some bugs:

Item icons painting on second layer. (Some description is above).
Event key passing in ComponentCompartmentInventory.java and WindowCompartment.java (read my dialog with Nedelosk).

RusTit · 2018-04-16T01:36:44Z

Item icon painting bug appears not only in the search window.
You can also see it in the slider (in which custom tab settings are set).

mezz · 2018-04-16T01:37:22Z

If you have specific fixes for the changes made in this PR, I think that is fine.
I am just worried that this PR is going out of control, it seems to be fixing too many different things.

RusTit · 2018-04-16T01:39:28Z

Not yet. I do not know how to fix a bug with rendering. I will fix the error with the key a little later with separate commits (will be last in this PR)

RusTit · 2018-04-16T03:18:04Z

Apparently there is no bug with keys.
I did debugging by checking the passed string-keys through the events, in everything is ok.
P.S. but the bug with the renderer I can not solve myself.
