* Restore MD5-Timestamp performance by removing try/except from every call. ↵William Deegan2019-06-262-44/+75
| | | | Also some optimized logic for updating and using the dependency_map built as part of the decider. Fixed tests. Note Deciders now need a fourth argument 'repo_node' which is the repository node for the file if it's to be used. This is currently only used by md5-timestamp decider File.changed_timestamp_then_content()

| |/ | | | | | | | | | | | | | | | | | | | | | | Consistently use "not is" and "not in", many instances used the form "not x is y" instead, which pylint objected to. A couple of bare except clauses got a qualifier. Files otherwise touched had trailing whitespace cleaned up as well. These are all things that sider would complain about if a change happened nearby, so this is pre-emptive. Signed-off-by: Mats Wichmann <mats@linux.com>

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Assorted fixups: exception types, redefined functions, globals, etc. Some old code removed to resolve issues (hashlib is always present on modern Pythons; no longer need the code for 2.5-and-earlier optparse). cmp is not a builtin function in Py3, drop one (unused) use; replace one. Fix another instance of renaming to SConsEnvironmentError. TODO flagged some instances of doing a raise without argument but not inside a try block - this is not considered legal, since raise with no argument is for re-raising an exception, but I don't know exactly how to resolve this in these cases. Also flagged an instance of raising an int instead of an exception class. We can either leave these as markers or update the PR. Signed-off-by: Mats Wichmann <mats@linux.com>

|/ | | | components to dependency list. Updated test. TODO: better formatting
* Clean up some file opens, regex stringsMats Wichmann2019-03-071-2/+2
| | | | | | | | | | | | | | | | | | Most recent Python (3.8 alpha) spews warnings aplenty about two subjects: unclosed files and strings which look like they have embedded escapes that Python does not recognize. The latter are usually regexes, and it provides a reminder that regular expressions should normally be specified as raw strings, so Python does not attempt to interpret them. Irritating is that even docstrings are flagged, it's not obvious what the right answer is for a docstring which contains, say, a Windows-style path with backslashes. This converts a bunch of opens that are not closed into context manager usage and regex patterns into raw strings. This eliminate about 4000 warnings spewed by Py3.8 (9200 remain).
