donate-cpu-server.py: Fix #9192: Old results are shown in the reports (#1941)
Trac ticket: https://trac.cppcheck.net/ticket/9192
This commit also fixes that negative values of the elapsed time are
used for calculating total times. These crashes and errors are now
ignored in the time report since there is no useful timing information
in that case.

Tested with a local daca@home server with old and new results.

Cppcheck developer and build tools

##¤ * tools/astyle-client.py

With this tool you can astyle-format arbitrary cpp/header files even if you do not have astyle on your computer.

astyle on a server is used.

Example usage:

python tools/astyle-client.py lib/token.cpp

The file is reformatted and a status message is written that says if there were any changes or not.

This script is a lot slower than running astyle locally on your computer.

* tools/matchcompiler.py

The matchcompiler.py is a build script that performs a few code transformations to .cpp files under the lib directory. These transformations are related to the use of Token::Match() function and are intended to improve code performance. The transformed files are saved on the build directory. This tool is silently used when building the code with SRCDIR=build, that is:

$ cd path/to/cppcheck
$ make MATCHCOMPILER=yes

Here is a simple example of the matchcompiler.py optimization. Suppose there is a file example.cpp under lib/:

// lib/example.cpp
void f1() {
    Token::Match(tok, "abc");
}

void f2() {
    const char *abc = "abc";
    Token::Match(tok, abc);
}

If you manually run matchcompiler.py from the main directory:

$ cd path/to/cppcheck
$ python tools/matchcompiler.py

A file example.cpp will be generated on the build directory:

// build/example.cpp
#include "token.h"
#include "errorlogger.h"
#include <string>
#include <cstring>
static const std::string matchStr1("abc");
// pattern: abc
static bool match1(const Token* tok) {
    if (!tok || !(tok->str()==matchStr1)/* abc */)
        return false;
    return true;
}
void f1() {
    match1(tok);
}

void f2() {
    const char *abc = "abc";
    Token::Match(tok, abc);
}

From this we can see that the usage of Token::Match() in f1() has been optimized, whereas the one in f2() couldn't be optimized (the string wasn't inline on the Token::Match() call). The developer doesn't need to use this tool during development but should be aware of these optimizations. Building with this optimization, cppcheck can get a boost of 2x of speed-up.

* tools/dmake.cpp

Automatically generates the main Makefile for Cppcheck (the main Makefile should not be modified manually). To build and run the dmake tool execute:

$ cd path/to/cppcheck
$ make dmake
$ ./dmake

* tools/reduce.py

Script that reduces code for a hang/false positive.

* tools/times.sh

Script to generate a times.log file that contains timing information of the last 20 revisions.
