Alexander Mai 521e6c48b5 Minor fixes for signal handling: make global variables static, enhance stack vs. heap detection for recognizing stack overflows 2015-03-07 20:47:27 +01:00

Thomas Jarosch ec21134817 Fix false negatives for local suppressions
Introduce a new bool setting jointSuppressionReport
that will be set by the analyseWholeProgram() code path.

When the flag is enabled, unmatched suppressions are
collected after running the final whole program analysis
to prevent false positives for the unusedFunction check.

The check functions in the unit test
for single / multi file suppressions were unified.

Kimmo Varis 68c52ddd69 Refactoring information messages.
Currently the information severity messages are outputted as error
messages with Severity::Information. This causes constant confusion
as people think it as mildest error severity (and rightfully so).
When it was meant to be for printing messages about the checking
procedure itself (like missing header files etc).

So I'm adding a new function for the ErrorLogger for printing these
informative messages. This makes clear the distinction of errors
found from the code and messages related to the checking itself.
It also makes it easier for clients to handle these separately.

Kimmo Varis c7d99fe9a7 Remove ErrorLogger::reportStatus() method.
The ErrorLogger::reportStatus() is not lib code interface. The CLI
code does the looping through file list and gives one file at a
time for the core code. Hence lib has no any idea about the
progress and it can't provide such information.

Also the recent commit (6d858b6) caused a GUI build failure by
adding CLI code dependency to GUI. Which is big no-no.

This is admittedly a hack. But it allow us to build all modules
again.

Kimmo Varis f240574107 Modify the Cppcheck class to check one file at a time.
Unify usage and API of CppCheck class. Allow only one file checked
at a time, instead of list of files. Clients can then handle file
lists more naturally and as they see fit. Also clients have better
knowledge of how checking status should be handled.

The single-threaded CLI checking was only one using the file list.
Other clients were giving files (to list) one file at a time.

Kimmo Varis 903769a388 CLI: Give files to Cppcheck class one at a time.
When doing single-threaded checking give checked files to Cppcheck
class one file at a time. Like GUI and multithreaded checking
already do. This unifies how we call Cppcheck class from different
clients.

Kimmo Varis 6401271ceb Add CLI support for ignoring paths.
Add support for giving list of ignored paths from CLI. This way
user can define paths one doesn't want to check (like generated
code). This first simple implementation only does exact matching,
no support for wildcards etc. And matching is always agains dir
names.

If the filtered dir name is part of the checked filename then the
file is ignored.

help or listing errors. So add new attribute for CmdLineParser to
track use of these options and exit before checking files when
the attribute is set.
