When running the git hook, even though the appropriate config file is
found and processed, the exclude patterns and paths were not being
corrected to account for the temporary directory that we copy the files
into.

If we handle an exception, or early exit, or really anything, we should
exit non-zero (and we used to). This was a minor oversight.

Do not print the source when provided with -q
When users specify any number of -q's on the command-line, we should not
show the source even if they have otherwwise configured Flake8 to do so.

When we enable a plugin (when it's provided in the --enable-extensions)
plugin, we need to remove it both from the extended default ignore list
and the plain ignore list.

Change how we initialize our git hook application
Look for configuration files in the current directory while checking the
files in the temporary directory.

Previously, we didn't handle the case where an error code was implicitly
ignored (by not being in --select) and implicitly selected (by not being
in --ignore). This means we need to update StyleGuide#_decision_for and
StyleGuide#is_user_selected to handle these cases.

Add --tee option to split report output stream.
The `--tee` option allows the linter report to be written to stdout, even
though it is being redirected to a file with the` --output-file` option.
This is useful if I want to store the report in a separate file for later
analysis but also be able to print the output on screen (e.g when running
in a CI environment).
See merge request !90
We opted to not copy the file_tokens attribute each time it's accessed
in the merge request discussion but it was never reflected in the code.
Further, the attribute had no documentation or docstring, so we've added
that. Finally, we address a personal style nit that I otherwise wouldn't
have picked at.
In some cases, when we handle SyntaxErrors we need to ensure that the
column number is correct for a 1-indexed report. In some cases, we also
need to account for the fact that the SyntaxError has happened "after" a
new-line. To extract and alter the row and column numbers, we've moved
the logic to a private static method on the FileChecker object to avoid
an overly complex method.
Closes#237
When a SyntaxError is raised, column_number may be None. Unfortunately,
it's not obvious where that None comes from so we must handle it in
handle_error.
Closes#214
Add --bug-report flag to help bug reporters
When invoked it will print out JSON that has all of the debugging
information needed by the maintainers to diagnose or reproduce a bug.

Serialize Checkers PluginTypeManager to a dict
*Description of changes*
Try to side-step issues with attributes not being set/updated on plugins when used with multiprocessing and Queues.
*Related to:* #179, #164
See merge request !98
It seems likely that the multiprocessing module on Windows is not
capable of serializing an object with the structure that we have and
preserving the attributes we dynamically set on plugins (like the
FlakesChecker). To avoid issues like this with all plugins (although
we have only found this on Windows with the FlakesChecker), let's try
serializing the Checkers PluginTypeManager to a dictionary so that the
only object that a Queue is really trying to serialize/deserialize is
the FlakesChecker itself.
Related to #179
Previously, all testing was done from the directory in which the
configuration file lived, so this bug went unnoticed. However, if you
run Flake8 against its own source from a directory above, you would
notice that the patterns in the exclude config value in tox.ini were
ignored. This is because we (like any reasonable person) are using
relative paths. The path is relative, however, to the directory in
which the configuration file was located. So we keep track of which
directory that is and use that to normalize the paths in the config
file.
Yes, there is an unrelated change to our tox.ini in this commit as
well. ;-)
Closes#194
Due to https://bugs.python.org/issue27649, we cannot continue to
expect multiprocessing to work as we expect and document it on Windows.
As such, we are going to revert back to our previous behaviour of
disabling it across all versions of Python on Windows to provide the
default expected behaviour of Flake8 on that Operating System.
Previously, to ensure that plugins on by default were reported, we
added them to the select list. This means that ignoring them became
impossible. To accomodate our reporting logic and a user's ability
to ignore, we need to keep our select and extended select lists
separated.
This allows us to have a better understanding of who is selecting what,
where, and how and make our decision as to whether or not an error
should be reported more wisely.
Closes#195
