Improve support for labels in simplifyAddBraces step ( #3278 )
...
Previously only a single regular label before a compound statement was
allowed in simplifyAddBracesPair() after if/switch/do/while/for.
This patch adds support for:
* case-labels;
* labels before a single statement;
* labels before try/catch blocks;
* multiple consecutive labels.
Additionally the code for skipping a case label was extracted into a
separate function from simplifyLabelsCaseDefault() and reused in
simplifyAddBracesPair().

Fix AST for brace initialization after decltype() ( #3245 )
...
Currently sub-expressions like decltype(x){} break AST creation for
subsequent tokens in the whole expression. In some cases this triggers
validation checks in validateAst() and analysis on the file stops.
For example, code like this:
int x = decltype(0){} ? 0 : 1;
currently produces internalAstError.
To fix the issue iscpp11init_impl() was changed to recognize { preceded
by decltype(expr) as a start of C++11 brace initialization expression.

Fixed #9729 (AST broken: lambda with noexcept keyword) ( #3243 )
...
The previous fix for the issue (43b58dbc9e
) didn't seem to actually fix
it because it added a check for noexcept without a condition, but when
AST is created noexcept always has a condition due to simplification
from "noexcept" to "noexcept(true)" in Tokenizer::simplifyKeyword().
The issue from the ticket couldn't be reproduced neither on 43b58dbc9e
nor on the previous commit, so it is hard to tell whether the fix was
effective or not.
The issue appeared again after a refactoring of AST code in ac67049661
.
Test added with the original fix was unable to catch that because it
used testAst() helper function which skips most simplification steps.
To fix the issue we now check for noexcept with a condition and add a
proper regression test that:
1. Uses tokenizeAndStringify() to ensure that all simplifications are
performed before AST is created.
2. Parses the code snippet from the ticket, as having "if (cond)" is
crucial to reproducing the original issue (internalAstError).
Also fix AST creation for lambdas that have both constexpr and mutable
keywords.

Fix varId assignment for uses of variables declared in the if condition ( #3231 )
...
Variables declared in the if condition (or in C++17 init-statement) are
visible not only in the if body but also in the else body. But logic in
Tokenizer::setVarIdPass1() handled such variables as if they were
declared in the if body.
As the result they were removed from variablesMap by the time the else
block was parsed and their uses in the else block were either given an
incorrect varId from variables in some outer scope or not given a varId
at all.
This then resulted in false positive unreadVariable errors for variables
declared in the if condition (or init-statement) and used only in the
else block.
Simplification from "else if ..." to "else { if ... }" was moved before
setVarId() to simplify detection for ends of blocks in if-else chains.

Read error locations in the correct order from XML ( #3226 )
...
When ErrorMessage::callStack elements are serialized to XML they are
saved in the reverse order. But when they read back from XML they are
added at the end of the list. Thus the round trip via XML reverses the
order of ErrorMessage::callStack.
From the user point of view it looks like the usage of the
--cppcheck-build-dir option sometimes (when the file wasn't reanalyzed,
but that is hard to spot) results in incorrect location info for some
diagnostic messages.
Moreover, when the first location matches some suppression rule and the
last doesn't match any (or vice versa), usage of --cppcheck-build-dir
results in some diagnostic messages appearing and disappearing seemingly
at random (again, depending on whether the file was reanalyzed or not).

Fix #9139 (leak when variable has const qualifier) ( #3159 )
...
Also, in the tests, change socket/close to resource to get error
messages which say "resource leak" instead of "memory leak".

Fix #10182 (FN memory leak with if-statement) ( #3151 )
...
Improve leak detections in if-statements. This is done by checking
for leaks every time a scope is left. This allows cppcheck to catch
more memory leaks, as well as improve some error messages which now
contain the line where the variable goes out of scope, instead of the
end of the function.

Improve handling of realloc in memory leak checker ( #3036 )
...
Mark realloced variables as realloced instead of freed. This allows
improved checking for code with error realloc handling.
If cppcheck finds an if-statement which checks the validity of the
allocated memory or resource, check if the memory/resource is
reallocated from another variable. If so, we can add checking of that
variable in the if-statement instead. This allows to check that variable
for memleaks and double frees.
This fixes #9292 and #9990 which both concern FPs with double frees
after correct error handling.

Bugs should be exposed and fixed properly rather than just hiding them.

Add find_package(tinyxml2) to CMake builds ( #2691 )
...
So far, the cmake files of Cppcheck needed to be patched in order to
use installed tinyxml2 instead of the bundled version of tinyxml2.
- Introduce the CMake option USE_BUNDLED_TINYXML2 with a default value
of ON. This preserves the behavior as in the past and uses the
bundled version under externals/tinyxml2 by default.
- Usage of the installed tinyxml2 version of a system can be enabled
now using -DUSE_BUNDLED_TINYXML2=OFF as a cmake parameter.
- Some Linux distros do not install tinyxml2*.cmake files, which are
required to find tinyxml2 using find_package().
Try first using find_package(tinyxml2 QUIET) and if this fails, try
again using find_library(tinyxml2_LIBRARY tinyxml2)

fix #9983 (TemplateSimplifier: template not simplified : f(0,0);) ( #2905 )
...
Currently template type deduction for functions only works for single
template argument single function argument functions with a literal
argument.
This patch starts to add support for single template argument multiple
function argument functions. It correctly handles functions with
multiple arguments of the same type. It also handles a mix of template
and non-template arguments.
It does not add support for overloading non-template arguments.
It does not add support for multiple parameter template functions.
It does not add support for type deduction from variable arguments.

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.

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.

Avoid clarifyCalculation warning for 'x % 16 ? 1 : 0' expression. Fixes FP seen in daca@home. It seems likely that the order is understood otherwise the ternary calculation could easily be simplified away.

Fix false positives with condition with || and &&
...
The value of something in the middle of a condition with mixed || and &&
gives no information on which branch will be taken.
For instance with:
```
int f(int a, int b, bool x) {\n"
if (a == 1 && (!(b == 2 && x))) {
} else {
if (x) {
}
}
return 0;
}
```
We can enter the if part whether x is true or false, and similarly,
enter the else part whether x is true or false. Same thing with the
value of b.
This fixes the following false positive with above code:
```
:4:13: style: Condition 'x' is always true [knownConditionTrueFalse]
if (x) {
^
:2:33: note: Assuming that condition 'x' is not redundant
if (a == 6 && (!(b == 21 && x))) {
^
```

Add missing operators <<= and >>=
...
This fixes issues (at least false positives) in code using them.
For instance:
```
unsigned compute(unsigned long long a) {
unsigned num = 0;
while (a > 0xFFFFFFFF) {
a >>= 32;
num += 32;
}
if (a > 0xFFFF) {
a >>= 16;
num += 16;
}
if (a > 0xFF) {
num += 8;
}
return num;
}
```
would give false positive:
```
cppcheck --enable=style sl3.cpp
Checking sl3.cpp ...
sl3.cpp:11:11: style: Condition 'a>0xFF' is always false [knownConditionTrueFalse]
if (a > 0xFF) {

sl3.cpp:3:14: note: Assuming that condition 'a>0xFFFFFFFF' is not redundant
while (a > 0xFFFFFFFF) {

Fix some false positives when the same expression at different places does not have the same value
...
Typically with
```
int F(int *f);
void F2(int *a, int *b) {
int c = *a;
F(a); // modifies *a
if (b && c != *a) {}
}
```
we would get the following FP:
```
[test.cpp:3] -> [test.cpp:5]: (style) The comparison 'c != *a' is always false because 'c' and '*a' represent the same value.\n
```
I guess it boils down to isSameExpression only checking that the
expression is the same (in the above case, "*a" and "*a" are indeed the
same), but there's not real check on the values.
So the patch here is a bit hackish, and we still have false negatives in
cases with dereferenced pointers.

Fix #9652 (fp memleak with function call with cast)
...
When the first argument was (void *)(1), at the start of the second
iteration, arg was pointing to the "1", which caused problems for
nextArgument(), which saw the ")" as the next token and returned
nullptr, signalling that there are no more arguments.
Instead, save the first token in the argument, which makes
nextArgument() do the right thing.

9769: Improve value flow for ternary operator
...
In some cases, the condition of the ternary operator is assigned a known
value after the two possible results, and in such cases, we would not
take the opportunity to assign a value to the ternary operator (and to

* 9768: Fix ast with throw in the middle of return
```
int f(bool x)
{
return x ? 0 : throw 0;
}
```
The `throw` part was not included in the ast, leading to an invalid
ternary operator.
* 8526: Fix ast construction for ternary operator
This tries to decide a bit more properly when ':' can be part of a
ternary operator. More precisely, there are some times when we want to
delay the construction of the ast for ':', so that it is place
accordingly to the matching '?'.
Typically, this fixes an issue with
`return val < 0 ? throw 1 : val;`,
where the ast for ':' would be constructed during as part of the
`throw`, and the ast for `?` would be invalid.
This patch is a bit of a hardcode, stating that we don't expect ':'
inside a throw, unless there is a complete ternary operator in there
(there can't be a range based for loop, a case in a switch). When we
reach ':', we know we are and the end of the `throw`.

gtk.cfg: Fix syntax errors and false positives ( #2552 )
...
A missing definition for g_assert_cmp*() causes syntax errors if code
like g_assert_cmpint(a, ==, b); is encountered.
The function g_hash_table_iter_replace() does not have to be marked
with leak-ignore since the memory could be freed later if corresponding
functions are present in the GHashTable. Since we can not know if this
is the case we have to assume that the memory is freed to avoid false
positives. The same is true for g_hash_table_insert() and
g_hash_table_replace().

Improve isSameExpression for literals ( #2514 )
...
Improve isSameExpression() for literals with same value but different
representation, for example the following different ways of
representing 9 as double: 9.0, 0.9e1 and 0x1.2p3.
With this change, cppcheck can (for example) correctly detect that the
else if statements are always false in the following example:
void f(double x) {
if (x < 9.0) {}
else if (x < 0x1.2p3) {}
else if (x < 0.9e1) {}
}

Fix 9577 (endless recursion in Valueflow::bifurcate()) ( #2492 )
...
Ensure bifurcate() does not recurse endlessly where a variable is
initialized recursively, or a variable is initialized as x(0) or x{0}
followed by a recursive assignment (for example int x(0); x = x / 1;).
The first case is solved by bailing out if there initialization is done
using x(0) or x{0}, the second by adding a missing depth argument to a
recursive call.

Fix 9546: properly check that the bound is the size ( #2475 )
...
Previously, as the check was done on the token and not on the ast,
`i <= v.size()` and `i <= v.size() - 2` would both raise the same
warning.
This patch fixes this, but this mean the check is only done when the
condition if `i <= v.size()`. Any other (more complex) condition is
ignore, and so we have false negative for instance with
`i <= v.size() + 1`.

This workarounds false positives 'Parameter can be declared with const [constParameter]'
when said parameter is used in constructor call. It assume the
constructor call might change the parameter (without any checks.
The drawback is that we have false negative, in cases where we could
check the constructor actually takes a const reference, or a copied by
value parameter.

errorlogger.cpp: Handle empty file-name like "*" (unmatchedSuppression) ( #2440 )
...
Using "--suppress=unmatchedSuppression" did not suppress the error-id in
all files, one needed to specify "*" as file-name. This commit also
allows empty file-names to suppress "unmatchedSuppression", not only "*"
or the exact file-name.
The manual uses the following example for suppressions specified in a
file:
// suppress all uninitvar errors in all files
uninitvar
This example suggests that no "*" has to be used to get suppression in
all files. I think that the command line parameter should work in the
same way.

* Avoid some additional memleakOnRealloc false positives
checkReallocUsage() already contains code to suppress the
`p = realloc(p, size)` error message when the pointer has been
previously copied from another variable (hence there is an additional
copy of the original pointer value) within the same function, as in
the added realloc21() test case.
Extend this so that `p = *pp` and `p = ptr->foo` are also recognized
as copies from another variable with the same original pointer value,
as in the added realloc22() and realloc23() test cases.
