* Get stack traces for daca@home crashes
If a command in daca@home crashes, execute it again within gdb to get a stack trace.
* donate-cpu.py: added "gdb" to checkRequirements()
* donate-cpu.py: handle wget failures
* donate-cpu.py: added --no-upload option to disable all uploads
* donate-cpu.py: set max_packages to 1 if --package is provided to avoid endless processing of the same package
* donate-cpu.py: no longer treat missing sources as a crash
* donate-cpu.py: fixed wget "http://: Invalid host name." error caused by empty argument in subprocess.call()
* donate-cpu.py: added --no-upload to --help
* donate-cpu.py: detect crashes when using -j1
* donate-cpu.py: added -g to compiler flags
* donate-cpu.py: fixed gdb call and stacktrace printing / always pass "-j1" to gdb call so the exception will actually occur in the application
* donate-cpu.py: removed left-over --verbose from wget call
* donate-cpu.py: removed unnecessary break
* donate-cpu.py: only use gdb for crash in head run / actually provide the stack trace for the output
* donate-cpu.py: include the last checked file with the stack trace
* donate-cpu.py: removed unnecessary wget() call and a sleep in it / also inverted some logic
* donate-cpu.py: small hasInclude() optimization
* donate-cpu.py: bumped version number
* donate-cpu.py: detect start of gdb output when Cygwin is used
The Cygwin output looks like this:
Thread 1 "cppcheck" received signal SIGSEGV, Segmentation fault.

The official documentation recommends to include the Python C API via
`#include "Python.h"`:
https://docs.python.org/3/c-api/intro.html
And many projects do it exactly this way, that is why the client script
often does not detect the usage of the Python C API.
The client script will exit after the specified number of packages
have been processed. 0 means infinitely.
Useful for example to regularly quit the script, check for updates to
the client and start it again. Or as an alternative to the `--stop-time`
argument.
Python 3 directly decodes the text when it is read(). If there is any
invalid UTF-8 character in the text an exception is thrown (IIRC it is
UnicodeDecodeError). Opening the file with `error='ignore'` avoids
throwing an exception and just ignores the invalid character. Since
this is only possible since Python version 3 there must be extra code
for older versions.
The test script has been enhanced. It now also uses a package which
contains a file with at least one invalid UTF-8 character.
Now also found:
- Includes directly at the beginning of a file
- Indented includes
- Includes where there is no white-space between
"include" and header name
The function libcerror_error_set() is currently the function for which
daca@home most often reports a missing configuration (more than 80000
times).
Official repository of libcerror: https://github.com/libyal/libcerror
The library configuration has been tested with the library libvhdi:
ftp://ftp.se.debian.org/debian/pool/main/libv/libvhdi/libvhdi_20181227.orig.tar.gz
This detects more includes / headers. For example includes like
"# include <gtk/gtk.h>" with a space before "include" as it is used in
the package http://cppcheck.osuosl.org:8000/gbatnav are now also
detected.
The regex search also searches all includes for one library in one go
instead of one include per loop.
Tested with several packages to make sure libraries that were detected
before are still detected.
If "head" and "OLD_VERSION" both crash there are no messages and the
variable `results_exist" is set to False. But still the results must be uploaded
for the crashes to be saved also.
Tested with the package http://cppcheck.osuosl.org:8000/double-conversion
Only enable the library option for those configurations if the
corresponding .cfg file exists to not crash Cppcheck if an
older version than 1.87 is used as the "old" version.
The version number is added to the result output so issues could be more easily reproduced and in the future if it is necessary to handle any specific version of the client by the server in a special way (for example because it is erroneous) this is possible now.
Tested locally.
Searching for `#include <SDL.h>` does not always work. Sometimes `#include "SDL.h"` is used, but for now lets see for how many packages it works this way.
Add check to only use boost library if boost.cfg exists since it is very new.
If the boost.cfg does not exist Cppcheck would exit with an error and we
would not get the desired results.
For now the boost library configuration detection is commented out. It
should be enabled after the release of Cppcheck 1.87.
Tested locally.
Optimize checking of different includes for the same library by using a `list` instead of calling `hasInclude()` several times.
Add includes for gtk and qt library detection that were found missing when looking at several daca@home packages.

Enable information messages and "--check-library" in the Cppcheck
parameters.
Store the information messages and the rest of the messages in different
variables and upload them separately.
The server stores the information messages in a sub-directory similarly
to the normal issue messages in one file per package.
Reports for "checkLibraryFunction" and "checkLibraryNoReturn" message ids
are generated by the server now.
With this new option it is possible to limit the download rate / bandwidth that wget uses to download packages.
The value is verified by running wget with it and check if there is a parse error (exit code 2). If the value is not valid an error message is shown and the script exits with an error code.
Similar to the '--test' option for the donate-cpu-server.py script that lets the server listen locally on port 8001 the client now can also work against such a server by using the same option '--test'.
With Python3 f.read() directly returns a string object that has no
decode() function. As a workaround AttributeError exceptions during
calling the decode() function are ignored and the data read from the file
is left unchanged.
With Python2 calling the decode() function is necessary and still done.
Avoids git printing a warning about redirecting to https every time
the clone command is issued. The warning was:
warning: redirecting to https://github.com/danmar/cppcheck.git/
Use python tarfile instead of tar to extract the packages.
Only extract source files of interest.
Skip dangerous files that could overwrite files outside the temp folder.
Fixes https://trac.cppcheck.net/ticket/8716
When os.remove() tried to remove a file that did not exist (which is the case when the script is started for the first time or the working directory has been cleared) a FileNotFoundError was issued and the script just crashed.
