misra: Fix 8.2 false positives (#3309)
* misra: Fix 8.2 false positives

Fix false positives in rule 8.2 that occurred in cases when we have a
function definition and declaration in the same file.

For example, the following code generated false positives before this
commit:

```
void f(uint8_t * const x);
void f(uint8_t * const x)
{ (void)x; }
```

We need to distinguish the declaration and the definition, so the dump
file generation routine was extended to keep token where the definition
of the function. The analysis in the addon also been improved.

Closes Trac issue: https://trac.cppcheck.net/ticket/10219

Daniel Marjamäki 22727ee3ab Addons; split up possible/known values and impossible values. This is inconsistent with core Cppcheck, however the addons do not handle impossible values in general. A future improvement might be to clarify this somehow, maybe renaming Token.values. 2021-02-23 22:40:49 +01:00

cppcheckdata: Use instance attributes in Cppcheckdata (#3029)
This commit makes CppcheckData class to use instance attributes instead
of class attributes.

Since class attributes are mutable (list), when you append to them, they
don't promote to instance variable which means when you call parsedump()
multiple times data just gets appended to them.

misra.py: Fix R5.4 false positives with C99 (#2516)
* parser: Parse standards node at start event

This required, because we can loose data at the end event.

* misra.py: Fix 5.4 standard-dependent error

By default Cppcheck use C11 standard, so this change fix false positives
for rule 5.4 with C99.

* travis: force --std=c89 for misra.py

Georgy Komarov d977761e76 addons: Reduce memory consumption (#2395)
* addons: Reduce memory consumption

Parse dump files incrementaly using ElementTree.iterparse. Clean unused
resources during parsing.  This method is explained in following
article: https://www.ibm.com/developerworks/xml/library/x-hiperfparse/

Memory consumption was reduced about 30% (measured with mprof),
execution time increased about 5% (measured with time utility).
More description available in PR.

* Switch to lxml and update iterparse routines

Use lxml module instead default xml.etree. Lxml provides convenient
wrappers around iterparse method that accepts `tag` argument. That
easer incremental parsing routines to select specific tags from roottree
like `dump` and `dumps`.

Element.clear() method was replaced by `lxml_clean` because lxml
keeps additional information to nodes that should be removed.

Added note about large consumption RAM on large dump files.
This commit doesn't solve this problem completely, but provides a way
to improve current parser to add incremental Configuration serialization
later.

* Working on iterative parser

* Added iterative Configurations parser

* fix

* Fix varlist iteration

* make sure that standards node was loaded

Georgy Komarov 3bd126486f addons: Clean up and clarify addons usage. (#2359)
* addons: Add '--recursive' arg. Clean up and clarify errors messages.

This commit introduce '--recursive' option for cppcheck addons.
Iff this option is set addon will recursively traverse directories in
given input files to find files with '.dump' suffix that would be
checked. Otherwise it will treat input directory as error (current
behaviour).

Add additional error handling with more clear error messages, clean up
the code.

* Add regex specifier

* Roll back --recursive option

* Update addons section in manual

addons/cppcheckdata.py: Fix missing self, and wrong assignment. (#1919)
I am not sure but it looks like "self." is missing here.
And the attribute "inconclusive" is initialized as a "bool", so i guess
"True" should be assigned here?

eivindt 44670005ea Record C/CPP/Posix Standard used for cppcheck in dump file / use this for misra checking (#1782)
* Add cmd parameter for choosing between C90 and C99

Misra specifies different requirements to the uniqueness of
macros/enums/variables depending on what C standard
that's being used.

* Add standards configuration to each dump file

Read standards config from misra addon to decide what rules to use.

* Posix as standard setting should be deprecated.  Don't include this in the xml

* Rewritten to use a switch
