Note a curious extension to the std C rules: x, X and o formatting can never produce
a sign character in C, so the '+' and ' ' flags are meaningless for them. But
unbounded ints *can* produce a sign character under these conversions (no fixed-
width bitstring is wide enough to hold all negative values in 2's-comp form). So
these flags become meaningful in Python when formatting a Python long which is too
big to fit in a C long. This required shuffling around existing code, which hacked
x and X conversions to death when both the '#' and '0' flags were specified: the
hacks weren't strong enough to deal with the simultaneous possibility of the ' ' or
'+' flags too, since signs were always meaningless before for x and X conversions.
Isomorphic shuffling was required in unicodeobject.c.
Also added dozens of non-trivial new unbounded-int test cases to test_format.py.
resource files. The gist of the patch is to treat ".rc" and ".mc"
files as source files; ".mc" files are compiled to ".rc" and then
".res", and ".rc" files are compiled to ".res". Wish I knew what
all these things stood for...
which implements the automatic conversion from Unicode to a string
object using the default encoding.
The new API is then put to use to have eval() and exec accept
Unicode objects as code parameter. This closes bugs #110924
and #113890.
As side-effect, the traditional C APIs PyString_Size() and
PyString_AsString() will also accept Unicode objects as
parameters.
The cause was that the replace code necessarily used a PCRE internal
function to to template expansion.
The fix changes the code to use an SRE internal if SRE is used, and a
PCRE internal if SRE is used; in a way that should work with 1.5.2.
The solution can be sped up tremendously under the assumption that the
choice between sre and pre is not changed during the execution of the
program; especially replace-all will be slow.
But I'll leave that to someone else.
When reading a short, sign-extend on platforms where shorts are
bigger than 16 bits.
When reading a long, repair the unportable sign extension that was
being done for 64-bit machines (it assumed that signed right shift
sign-extends).
style conventions. (Ping has checkin privileges but apparently
ignores them at the moment.)
Ping improves a few doc strings and fixes style violations like foo ( bar ).
An addition of my own: rearrange the printing of various items in
test() so that the (long) environment comes at the end. This avoids
having to scroll if you want to see the current directory or command
line arguments.
I can't test this, so I'm just checking it in with blind faith in Andy.
I've tested that it doesn't broeak a non-Pth build on Linux.
Changes include:
- There's a --with-pth configure option.
- Instead of _GNU_PTH, we test for HAVE_PTH.
- Better signal handling.
- (The config.h.in file is regenerated in a slightly different order.)
