remove local hacking check
oslo libraries once have issue on its namespace, but they all have migrated to the right one during liberty cycle. It is time to drop temporary local checks for this issue. Since this is the only local check we have, this patch entirely removes all related files. Change-Id: I8fe7a59f51ee8af25e3dade70da645cd646fa0b4

Guidelines for writing new hacking checks
|
||||
|
||||
- Use only for Ceilometer specific tests. OpenStack general tests
|
||||
should be submitted to the common 'hacking' module.
|
||||
- Pick numbers in the range C3xx. Find the current test with
|
||||
the highest allocated number and then pick the next value.
|
||||
- Keep the test method code in the source file ordered based
|
||||
on the C3xx value.
|
||||
- List the new rule in the top level HACKING.rst file
|
||||
- Add test cases for each new rule to ceilometer/tests/test_hacking.py

|

This class tests the hacking checks in ceilometer.hacking.checks by
|
||||
passing strings to the check methods like the pep8/flake8 parser would.
|
||||
The parser loops over each line in the file and then passes the parameters
|
||||
to the check method. The parameter names in the check method dictate what
|
||||
type of object is passed to the check method. The parameter types are::
|
||||
|
||||
logical_line: A processed line with the following modifications:
|
||||
- Multi-line statements converted to a single line.
|
||||
- Stripped left and right.
|
||||
- Contents of strings replaced with "xxx" of same length.
|
||||
- Comments removed.
|
||||
physical_line: Raw line of text from the input file.
|
||||
lines: a list of the raw lines from the input file
|
||||
tokens: the tokens that contribute to this logical line
|
||||
line_number: line number in the input file
|
||||
total_lines: number of lines in the input file
|
||||
blank_lines: blank lines before this one
|
||||
indent_char: indentation character in this file (" " or "\t")
|
||||
indent_level: indentation (with tabs expanded to multiples of 8)
|
||||
previous_indent_level: indentation on previous line
|
||||
previous_logical: previous logical line
|
||||
filename: Path of the file being run through pep8
|
||||
|
||||
When running a test on a check method the return will be False/None if
|
||||
there is no violation in the sample input. If there is an error a tuple is
|
||||
returned with a position in the line, and a message. So to check the result
|
||||
just assertTrue if the check is expected to fail and assertFalse if it
|
||||
should pass.
