of the Template.delimiter attribute, we make use of the delimiter in the
escaped group, and in the safe_substitute() method more robust.
Now, .delimiter should be the unescaped delimiter literal, e.g. '$' or '&', or
whatever. The _TemplateMetaclass will re.escape() this value when it builds
the pattern.
High level error message was stomping useful detailed messages from lower
level routines.
The new approach is to augment string error messages returned by the low
level routines. The provides both high and low level information. If
the exception value is not a string, no changes are made.
To see the improved messages in action, type:
import random
class R(random): pass
class B(bool): pass
module type with silly arguments. (The exact name can be quibbled
over, if you care).
This was partially inspired by bug #1014215 and so on, but is also
just a good idea.
* The parameterization of "delimiter" was incomplete.
* safe_substitute's code for braced delimiters should only be executed
when braced is not None.
* Invalid pattern group names now raise a ValueError. Formerly, the
convert code would fall off the end and improperly return None.
Beefed-up tests.
* Test delimiter override for all paths in substitute and safe_substitute.
* Alter unittest invocation to match other modules (now it itemizes the
tests as they are run).
Renamed the new generator at Trevor's recommendation.
The name HardwareRandom suggested a bit more than it
delivered (no radioactive decay detectors or such).
with default False for testmod(). The real point of introducing this was
so that output from doctest.master.summarize() would be the same as in
2.3, and doctest.master in 2.4 is a backward-compatability hack used only
by testmod().
The list resizing scheme only downsized when more than 16 elements were
removed in a single step: del a[100:120]. As a result, the list would
never shrink when popping elements off one at a time.
This patch makes it shrink whenever more than half of the space is unused.
Also, at Tim's suggestion, renamed _new_size to new_allocated. This makes
the code easier to understand.
- Dictionary keys are in arbitrary order, but not random (which implies, well,
intentional randomness).
- Move a footnote closer to what it's talking about so that it doesn't look
like we're saying that "0 == 0.0" can't be relied on.
- Minor language tweaks in the vicinity.
