Merge lp:~mc-return/compiz/compiz.fix1030473-part1 into lp:compiz/0.9.8

[MC Return]

Fixed various problems described in bug 1030473.
Optimized performance and style following suggestions reported by cppcheck:

1. Reduced the scope of various variables.

2. Used prefix ++ operators for non-primitive types, because those can be more efficient than post-increment. Post-increment usually keeps a copy of the previous value, adds extra code and is slower.

Fixes various problems described in bug 1030473.

That's fine - you just need to fix the indentation on lines 9 and 13 of the diff (make it line up with the parens)

51 + int j;
52 for (j = 0; j < num; j++)
53 {

Indentation (should be 1 tab)

68 + int j, num = option.int_desc_size ();
69 for (j = 0; j < num; j++)
70 {

ditto ... there seem to be a lot of places where the indentation isn't quite right. Compiz uses the X11 scheme (which is stupid, but we shouldn't change it)

1 indent: 4 spaces
2 indents: 1 tab (8 wide)
3 indents: 1 tab 4 spaces
4 indents: 2 tabs

etc

You might want to change these:

505 - lastX = -1000000000.0;
506 + float lastX = -1000000000.0, lastZ = 0.0;
507

to

float lastX = std::numeric_limits <float>::min (), rather than their current magic number of -1000000000.0

596 - right = minWidth;
597 - top = 0;
598 - bottom = minHeight;

Keep these on separate lines, its a bit easier to read

[Daniel van Vugt (vanvugt)]

Lots of indentation needs fixing. Look at the Preview Diff.

I'm not concerned about multiple declarations on one line. It makes sense when the variables are related and/or the line is not very long.

review: Needs Fixing

[MC Return (mc-return)]

Daniel, I am sorry about the indentation problems.

I tried to not create any new ones ;), but the diff here shows the code differently than the code editor (QTCreator) that I am currently using - it seems that QTCreator is inserting spaces automatically, when I use Tabulator and I am a bit confused about the strange looking diff here...

Also when reading the code it seemed that inconsistent indentation was already an existing problem...

How about using some specialized tool to fix all of those indentation and stylistic problems automatically ?
I've heard recommendations for the code beautifier "Artistic Style" for example: http://astyle.sourceforge.net/

Also: Are the fixes already done in this branch ok so far, except from the wrong indentation, and do you have any comments on the remaining problems cppcheck found and how to best fix those ?

[MC Return (mc-return)]

The strange thing is that I did not touch the indentation at all, when I changed postfix to prefix operators for example, and it looks correct when I check it in QTCreator, but the diff here says otherwise... :(

Sometimes (in the for loops) Tabulator + 5 Spaces were used, I am not sure about those (I used TAB + 4 Spaces)...

The rest of the problems should now be fixed. I hope we can merge this branch ASAP, before starting work on the remaining problems cppcheck detected as those are the more complicated ones and should IMHO not be mixed into one large diff to provide better readability. That is why I named this branch compiz.fix1030473-part1 in the first place ;).

not
