(This also uses assertRaises as a context manager, but that is just for improved clarity.)
This begins to test the established version_info caching behavior.
This independence is also established caching behavior for version_info.
This reorganization is to facilitate using two separate fake git commands with different versions, in forthcoming tests.
For gitpython-developers#1836. This uses a property with the same logic as before for version_info caching, except that the _version_info backing attribute holds the value None, rather than being unset, for the uncomputed state. This rectifies the inconistency between the property's behavior and the way the associated states are represented by its __setstate__ and __getstate__ methods for pickling. Because the Git class only used LazyMixin as an implementation detail of the version_info attribute, it is removed as a subclass.
Instead of directly accessing the _version_info attribute. This fixes a new test failure since the way the public version_info property uses the _version_info backing attribute has changed, and also shows the usage that is documented (accessing _version_info was never guaranteed to work, and now no longer works as before).
This is trickier to test than the other cases, but important enough that I think it deserves its own test.
This also makes the xfail marking for Windows correct.
This enables it to run on Windows, removing the xfail marking. + Rename the test. + Add comments and reformat. The test still does not pass (on any platform) because it is one of the tests of the invalidation feature that is not yet implemented.
That is, that its value is not pickle serialized/deserialized, but always recomputed with a subprocess call the first time it is accessed even on a Git instance that is created by unpickling.
+ Put assertion only on the branch where mypy benefits from it.
This broadens the type annoation on the Git.version_info property, for gitpython-developers#1830. It also revises the docstring for clarity, and continues refactoring and comment changes (also for clarity).
This modifies two existing test cases to include an assertion about the length. These test cases are retained as there is value in testing on output from a real git command rather than only with test doubles. More importantly, this also adds a parameterized test method to check parsing of: - All numeric, shorter than the limit - all fields used. - All numeric, at the limit - all fields used. - All numeric, longer than the limit - extra fields dropped. - Has unambiguous non-numeric - dropped from there on. - Has ambiguous non-numeric, negative int - dropped from there on. - Has ambiguous non-numeric, number+letter - dropped from there on. The cases for parsing when a field is not numeric (or not fully or unambiguously numeric) currently all fail, because the existing logic drops intermediate non-numeric fields (gitpython-developers#1833). Parsing should instead stop at (or, *perhaps* in cases like "2a", after) such fields. When the code is changed to stop at them rather than dropping them and presenting the subsequent field as though it were a previous field, these test cases should also pass.
For gitpython-developers#1833. This makes version_info parsing stop including fields after the first non-numeric field, rather than skipping non-numeric fields and including subsequent numeric fields that then wrongly appear to have the original position and significance of the dropped field. This actually stops at (rather than merely after) a non-numeric field, i.e., potentially parseable fields that are not fully numeric, such as "2a", are stopped at, rather than parsed as "2".
