Bumps py from 1.8.1 to 1.10.0.

Changelog

Sourced from py's changelog.

1.10.0 (2020-12-12)

• Fix a regular expression DoS vulnerability in the py.path.svnwc SVN blame functionality (CVE-2020-29651)
• Update vendored apipkg: 1.4 => 1.5
• Update vendored iniconfig: 1.0.0 => 1.1.1

1.9.0 (2020-06-24)

• Add type annotation stubs for the following modules:

  • py.error
  • py.iniconfig
  • py.path (not including SVN paths)
  • py.io
  • py.xml

  There are no plans to type other modules at this time.

  The type annotations are provided in external .pyi files, not inline in the code, and may therefore contain small errors or omissions. If you use py in conjunction with a type checker, and encounter any type errors you believe should be accepted, please report it in an issue.

1.8.2 (2020-06-15)

• On Windows, py.path.locals which differ only in case now have the same Python hash value. Previously, such paths were considered equal but had different hashes, which is not allowed and breaks the assumptions made by dicts, sets and other users of hashes.

Sourced from The GitHub Security Advisory Database.

Regular expression deinal of service in py

A denial of service via regular expression in the py.path.svnwc component of py (aka python-py) through 1.9.0 could be used by attackers to cause a compute-time denial of service attack by supplying malicious input to the blame functionality.

Affected versions: ["< 1.10.0"]
