fix passedByValueError on enums (#2869) 2020-10-30 18:32:35 +01:00
Rikard Falkeborn d7a8e25d92
Fix #9647: Set correct enum value (#2856)
* Tokenize: Set varId for variables in enum

Set varIds in enum values. It was previously disabled in 5119ae84b8
to avoid issues with enums named the same as global variables. Take care
to only set varids to variables used to set the value of an enumerator,
not the enumerator itself. This is somewhat complicated by the fact that
at the time this happens, astOperand1(), astOperand2(), astParent() etc
are not set. The current implementation is not perfect, for example in
the code below, y will not have a varid set, but x and z will. This is
deemed sufficient for now.

            int x, y, z;
            enum E { a = f(x, y, z); };

* Fix #9647: Value of enums with variables as init values

C++ allows enum values to be set using constexprs, which cppcheck did
not handle before. To solve this, add a new pass to valueflow to update
enum values after global consts have been processed. In order to do so,
I moved all settings of enum values to valueflow. After setting the enum
values, we need another call to valueFlowNumber() to actually set users
of the enums.

There is still room for improvements, since each pass of
valueFlowGlobalConstVar() and valueFlowEnumValue() only sets variables
that are possible to set directly, and not if setting the value of a
variable allows us to set the value of another. For example

	constexpr int a = 5;
	constexpr int b = a + 5;
	enum E { X = a };
	constexpr E e = X;

Here both b and e will not have their values set, even though cppcheck
should be possible to figure out their values. That's for another PR
though.

This was tested by running test-my-pr.py with 500 packages. The only
difference was one error message in fairy-stockfish_11.1, where cppcheck
now printed the correct size of an array instead of 2147483648 which I
assume is some kind of default value. In that package, using a constexpr
when setting enum values is common, but as mentioned, there was no
change in the number of warnings.

Symboldatabase: Don't set unknown enum values (#2852)
Previously, if an enum value was set to a value unknown to cppcheck, the
next enum value would erroneously be set to the last set value plus one
(or zero, if no enum value had been set before). This partially fixes
Trac ticket #9647, in the sense that it no longer sets wrong values for
these enum values. Further improvements to this would be to set the
correct values instead. It also fixes the false positive mentioned in the
comments in the ticket.

Fix #9941: Return value type of library functions returning unsigned (#2848)
Fix return value types of library functions returning unsigned.
Previously, the valueType of auto x = f() would be signed even if f()
was specified to return an unsigned type.

This fixes #9941, which is a regression in cppcheck 2.2 compared to 2.1.
The regression was introduced in 32df807b22.

Rikard Falkeborn 5c061c1c12 Set correct type and size of string and char literals (#2275)
* Set correct type and size of string and char literals

Use that string and char literal tokens store the prefix. This makes
it possible to distinghuish between different type of string literals
(i.e., utf8 encoded strings, utf16, wide strings, etc) which have
different type.

When the tokens holding the string and character values have the correct
type, it is possible to improve Token::getStrSize() to give the correct
result for all string types. Previously, it would return the number of
characters in the string, i.e., it would give the wrong size unless
the type of the string was char*.

Since strings now can have different size (in number of bytes) and
length (in number of elements), add a new helper function that returns
the number of characters. Checkers have been updated to use the correct
functions.

Having the size makes it possible to find more problems with prefixed
strings, and to reduce false positives, for example in the buffer
overflow checker.

Also, improve the stringLiteralWrite error message to also print the
prefix of the string (if there is one).

* Add comment and update string length
