py-mako: updated to 1.2.3

1.2.3

Fixed issue in lexer in the same category as that of 366 where the regexp used \ 
to match an end tag didn’t correctly organize for matching characters \ 
surrounded by whitespace, leading to high memory / interpreter hang if a closing \ 
tag incorrectly had a large amount of unterminated space in it. Credit to \ 
Sebastian Chnelik for locating the issue.
As Mako templates inherently render and directly invoke arbitrary Python code \ 
from the template source, it is never appropriate to create templates that \ 
contain untrusted input.

1.2.2

Fixed issue in lexer where the regexp used to match tags would not correctly \ 
interpret quoted sections individually. While this parsing issue still produced \ 
the same expected tag structure later on, the mis-handling of quoted sections \ 
was also subject to a regexp crash if a tag had a large number of quotes within \ 
its quoted sections. Credit to Sebastian Chnelik for locating the issue.
As Mako templates inherently render and directly invoke arbitrary Python code \ 
from the template source, it is never appropriate to create templates that \ 
contain untrusted input.

1.2.1

Various fixes to the test suite in the area of exception message rendering to \ 
accommodate for variability in Python versions as well as Pygments.
Optimized some codepaths within the lexer/Python code generation process, \ 
improving performance for generation of templates prior to their being cached. \

1.2.0
Corrected “universal wheel” directive in setup.cfg so that building a wheel \ 
does not target Python 2.
The bytestring_passthrough template argument is removed, as this flag only \ 
applied to Python 2.
With the removal of Python 2’s cStringIO, Mako now uses its own internal \ 
FastEncodingBuffer exclusively.
Removed disable_unicode flag, that’s no longer used in Python 3.
Refactored test utilities into mako.testing module. Removed unittest.TestCase \ 
dependency in favor of pytest.
Replaced the use of pkg_resources with the importlib library. For Python < \ 
3.8 the library importlib_metadata is used.
Removed support for Python 2 and Python 3.6. Mako now requires Python >= 3.7.
Mako now performs exception chaining using raise from, correctly identifying \ 
underlying exception conditions when it raises its own exceptions. Pull request \ 
courtesy Ram Rachum.
