This directory contains configuration files to ignore errors found in
|
|
the build and test process which are known to the developers and for
|
|
now can be safely ignored.
|
|
|
|
To use:
|
|
|
|
$ cd <build directory>
|
|
$ make SOMETHING >& result
|
|
$ scripts/filter-known-issues.py result
|
|
|
|
It is included in the source tree so if anyone has to submit anything
|
|
that triggers some kind of error that is a false positive, it can
|
|
include the "ignore me" file, properly documented.
|
|
|
|
Each file can contain one or more multiline Python regular expressions
|
|
(https://docs.python.org/2/library/re.html#regular-expression-syntax)
|
|
that match an error message. Multiple regular expressions are
|
|
separated by comment blocks (that start with #). Note that an empty
|
|
line still is considered part of the multiline regular expression.
|
|
|
|
For example
|
|
|
|
---beginning---
|
|
#
|
|
# This testcase always fails, pending fix ZEP-1234
|
|
#
|
|
.*/tests/kernel/grumpy .* FAIL
|
|
#
|
|
# Documentation issue, masks:
|
|
#
|
|
# /home/e/inaky/z/kernel.git/doc/api/io_interfaces.rst:28: WARNING: Invalid definition: Expected identifier in nested name. [error at 19]
|
|
# struct dev_config::@65 dev_config::bits
|
|
# -------------------^
|
|
#
|
|
^(?P<filename>.+/doc/api/io_interfaces.rst):(?P<lineno>[0-9]+): WARNING: Invalid definition: Expected identifier in nested name. \[error at [0-9]+]
|
|
^\s+struct dev_config::@[0-9]+ dev_config::bits.*
|
|
^\s+-+\^
|
|
---end---
|
|
|
|
Note you want to:
|
|
|
|
- use relateive paths; instead of
|
|
/home/me/mydir/zephyr/something/somewhere.c you will want
|
|
^.*/something/somewhere.c (as they will depend on where it is being
|
|
built)
|
|
|
|
- Replace line numbers with [0-9]+, as they will change
|
|
|
|
- (?P<filename>[-._/\w]+/something/somewhere.c) saves the match on
|
|
that file path in a "variable" called 'filename' that later you can
|
|
match with (?P=filename) if you want to match multiple lines of the
|
|
same error message.
|
|
|
|
Can get really twisted and interesting in terms of regexps; they are
|
|
powerful, so start small :)
