Check if "python" is available, if not check for "python3" and use
the available Python interpreter. If no Python interpreter is found,
"make" fails with an according error message.
This solves the issue that not all modern Linux distributions any longer
install Python 2 by default, so "python" is not available and
"make MATCHCOMPILER=yes" would fail. Instead of forcing the users to
install Python 2, Python 3 is used in such a case now if it is
available.
* reduce.py: Allow reducing error messages, print output in case of error
Allow reducing code that triggers (false positive) error messages.
Print Cppcheck output in case Cppcheck returns unsuccessfully and no
segfault is expected. This helps fixing messed up command lines (for
example issues with the path).
* Use "else" as suggested
* donate-cpu.py: Add internal timing information of Cppcheck to output
The option "--showtime=top5" is added to the Cppcheck command line.
The timing output is collected and only for HEAD it is shown in the new
category "head-timing-info" in the results output.
The timing output is indented with one white space, so even in the
unlikely case that a function is named "head result:" or "diff:" it does
not break the parser in the server.
* donate-cpu.py: Also print the "old" timing information for comparison
Some projects only use this (older?) style of Qt header inclusion.
There are (older) books and examples which use this style, too.
It seems to be perfectly valid, so we should support it.
Previously, external files were not searched at all, and dependencies
on header files in cli was not taken into account for test files.
To add dependency of headers in externals, we also need to search for
includes with angular brackets.
There is no point in checking which libraries to use for each cppcheck
version since there is no change. Refactor the checking to a separate
function and run that once instead. This halves the time it takes to
check for libraries.
I looked into many packages where the detection failed and they all use
`#include "ruby.h"`. Some of these packages seem to be Ruby modules,
others seem to be "normal" software.
This adds one line in the package report to show the git hash and commit
date. This makes it possible to see exactely which revision the result
was obtained with.
The cppcheck head info line is now shown as
head-info: 1a25d3f9e (2019-08-30 18:34:14 +0200)
If there are *.diff files with old version numbers the server script
crashed because it always expects a key with the current OLD_VERSION.
This fix ignores entries in *.diff files that are not made against the
current OLD_VERSION.
Check if fetching and updating the cppcheck sources are successful. If
not successful after five retries, try removing the existing clone and
checkout again.
* dmake: Refactor object files to separate function
No functional change.
* dmake: Use range for loops
No functional change.
* Add all external cpp files instead of open coding
No functional change.
* Remove duplicate check.h in lib.pri HEADERS
* Add missing newline
No functional change, but the readability of the generated Makefile is
slightly improved.
Since the number of test files is larger than the number of lib files,
this only caused an extra harmless '\' being printed after the last
header file in lib.pri. If the number of test files would have been
smaller than the number of lib files, the generated lib.pri would have
been broken.
Sometimes there are no relevant source files (.c, .cpp, ...) extracted,
but other files are (.h, ...).
There could be only header files for example. Then Cppcheck returns with
exit code 1 and prints an error message. This is no crash and now no
longer reported as such.
Use renamed pylintrc file that is only meant for Travis checks.
Check all Python scripts in 'addons', 'htmlreport' and 'tools'
Errors for `_socketobject` class are disabled, see
https://stackoverflow.com/questions/10300082/how-to-prevent-python-pylint-complaining-about-socket-class-sendall-method
Install imported modules `unittest2` and `pexpect` via pip.
Add "./addons" to search-path for modules because
"tools/compare-ast-clang-and-cppcheck.py" imports cppcheckdata.py from
addons. Pylint does not seem to evaluate
`sys.path.insert(0, '../addons')` in the script. So an `init-hook` is
necessary in pylintrc_travis.
* donate-cpu.py: treat signal 6 (SIGABRT) as crash as well so we get a stack trace in the result
* donate-cpu.py: simplified returncode/signal check / also generate stack traces for SIGILL, SIGFPE, SIGBUS
* donate-cpu.py: avoid usage of "not" in if
* donate-cpu.py: do not overwrite returncode in crash handling
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.
Sources were built with Clang but with increased verbosity of error detection.
A number of syntax and semantic warnings were encountered. Commit adds
changes to correct these warnings.
Some changes involve removing extra, and unncessary, semi-colons at EOL
(e.g. at end of switch clause).
Project astyle settings are not currently setup to detect if a file is to
have an extra carriage return after the last line of data. Two files were
altered to ensure an extra carriage return.
An advisory to enhance code was encountered in triage code. Clang advisory
on a for-loop interation value suggested that:
`use reference type 'const QString &' to prevent copying`
Building on #1874, commit adds user controls to choose
or edit style in cppcheck-gui ONLY. Commit does not
address CodeEditor style usage in triage app at this time.
Code Editor style can be altered from the added "Code Editor"
tab in the user preferences. The user has the option to select
default light, default dark, or to customize.
If user leaves the style set to light or dark defaults, this
will be reflected in the choices shown in the preferences
dialog.
User choice for Code Editor Style is saved in the cppcheck-gui
preferences under the heading "EditorStyle".
* build: remove -Wabi and add -Wundef
gcc >= 8 throws a warning about -Wabi (without a specific ABI version)
being ignored, while -Wundef seems more useful (as shown by the change
in config.h, which was probably an unfortunate typo)
travis.yaml should probably be updated soon, but was left out from this
change as the current images don't yet need it
* lib: unused function in valueflow
refactored out since 8c03be3212
lib/valueflow.cpp:3124:21: warning: unused function 'endTemplateArgument' [-Wunused-function]
* readme: include picojson
* make: also clean exe
Packages now can contain something like:
```
head results:
Checking temp/openvdb/Platform.cc: __GNUC__=1...
[New Thread 7892.0x91c]
```
"New Thread 7892.0x91c" was wrongly identified as messageId in the HEAD
report.
This commit adds code to skip lines that start with `[` or where the
messageId contains at least one space.
* donate-cpu.py: made exitcodes > 0 negative so they will be detected a crash / changed the ThreadExecutor error to -222
* donate-cpu.py: unconditionally upload results and info now that errors are properly handled - will also properly clear the result/info in case there are no more messages
* donate-cpu.py: bumped version
* donate-cpu.py: added stdout to output in case of exitcode != 0
* donate-cpu.py: do not scan packages with no relevant files
* donate-cpu.py: bumped version
If an upload fails, the reason (exception text) is now printed.
Fix: If the last retry failed do not wait until continuing.
Remove some obsolete "fast" code in the uploadResults() function.
Tested with Python 2.7.16 and Python 3.6.8.
Since the directory for the results does no longer exist on the server,
the server currently crashes every time older clients try to upload
experimental fast results via "write-fast" command.
Now this command is just ignored so the server is instantly ready
again after a "write-fast" command.
* donate-cpu.server.py: increased "Package" column width for latest report and small cleanup
* donate-cpu.server.py: added date and time to crash report
* donate-cpu.server.py: simplified strDateTime()
* donate-cpu.server.py: add stale report to show results which are older than 30 days
* donate-cpu-server.py: added version and some logging
* threadexecutor.cpp: streamlined error messages
* donate-cpu.py: detect additional signals and exitcode != 0 as crash as well and (ab)use elapsedTime to make the errorcode visible in the output / also detect ThreadExecutor issues
* donate-cpu.py: bumped version
* donate-cpu.py: fixed detection of ThreadExecutor errors
* 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.
The function `iteritems()` of `dict`s is deprecated. The recommended
alternative is to use `items()`, this function also works with Python 2.
The next issue is that lambdas can no longer unpack tuple parameters
in Python 3. It would be possible to use some workaround and still use
a lambda, but using `operator.itemgetter(1)` instead is faster and the
recommended method in such a case.
The syntax is now compatible with Python 2 and 3 but the server script
still does not work with Python 3. For example `socket.recv()` returns
`bytes` in Python 3 and `str` in Python 2. Currently `str` is expected
so it does not work with Python 3.
In my tests there were about 1500 additional packages
available as bz2 on the server.
For some packages a newer version is now used if it is
only available as .tar.bz2 archive.
The donate-cpu.py client is tested to work with .tar.bz2
files under Python 2.7.15 and 3.6.8.
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
Ignore normal results (not fast or info) where the diff was made against the wrong OLD_VERSION. This avoids unwanted results when some client still analyzes an old package but the OLD_VERSION in the server script is changed for example.
Results missing the Cppcheck version info completely are also ignored.
Tested locally with correct and wrong version numbers.
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.
Two logging handler are added. One just prints all output with at least INFO severity to the console. The other only prints ERROR severity and above to a rotating file. The file size is limited to 100 kB. Since one backup file is used that results in a maximum of 200 kB disk usage.
The log file is saved in the directory where the server script is.
Hopefully this way some issues can be found more easily.
Tested locally.
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.
The checkLibraryFunction report is currently about 15 MB in size, lists more than 140000 functions and takes a long time to be generated.
Limiting the functions that are shown should save bandwidth, time and other resources on the server (and client that downloads the report).
Tested locally.
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.
Indirectly the scripts (at first the server test script) also document what needs to be done to setup a (local) server.
The productive client script can be used by everyone who wants to support daca@home, not only for testing. But i still think it is good to have it under /test to not lose too much clarity / lucidity in the /tools directory.
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.
* donate-cpu-server.py: Fix that results of package "crash" can not be viewed
Rename crash report page from "crash" to "crash.html" so the url ending with "crash" shows the results of package "crash".
* Also rename "diff" and "head" reports to *.html
In case there would be such packages in the future this avoids conflicts.
Related trac ticket: https://trac.cppcheck.net/ticket/8947
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.
Column width can now be easily changed via the `column_width` array.
Increased column width for the packages column so it is more likely that the date is not dropped.
Increased the column width for the number of results since there are packages which have about 100000 results.
Changes:
- Fixed compiler warnings
- Add "*.*" to file open menu so files without suffix can be opened
- Make it work under Windows
- Make wget() and unpackArchive() methods so they can access the UI
- wget() and unpackArchive() use the new method runProcess() now that also does some error handling
- Errors are shown in the status bar for easier debugging / usage
- Add readme.txt
- Let travis build the triage tool
Changes:
- Rename "time" page to "time.html" to avoid conflict with "time" package
- Output content as HTML instead of plain text
- Format head row of preformatted table bold
- Show factor for total time now too
Tested locally
Format the time output so the columns have the same width (as long as a text is not too long).
Add showing the factor of the time difference so very suspicious differences can be seen instantly.
Made the function body more PEP 8 conform by using lowercase variable names with underscores as delimiters.
Tested locally.
* Clean up redundant actions in travis jobs.
* Drop validatePlatforms from Makefile target checkcfg
* Print out CPU count. Adjust parameters for parallel jobs to 2 - the current result.
Instead of searching for a specific year (which could change) the script searches now for the current and last year to find the date and time information in the results.
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/
newer versions of git use a variable lenght proportional to the
repository size (9 for cppcheck)
remove old chomp helper function and make copying the revision
smarter to hopefully cover for edge case that needed it
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.
