bffd683f73 The rest of the changes by Trent Mick and Dale Nagata for warning-free 
compilation on NT Alpha.  Mostly added casts etc.

687ef6e70b On Linux, one sometimes sees spurious errors after interrupting 
previous output.  Call clearerr() to prevent past errors affecting our
ferror() test later, in PyObject_Print().  Suggested by Marc Lemburg.

57072eb79f Implement the other easy thing: repr() of a float now uses %.17g, 
while str() uses %.12g as before.

121ee2722e long_format(): Now takes a third parameter, addL; iff true, a 
trailing 'L' is appended to the representation,
                otherwise not.

                All existing call sites are modified to pass true for
                addL.

                Remove incorrect statement about external use of this
                function from elsewhere; it's static!

long_str():     Handler for the tp_str slot in the type object.
                Identical to long_repr(), but passes false as the addL
                parameter of long_format().

153a27ceb2 do_strip(): Fixed cut-and-paste error; this function should check for 
zero arguments (found by Marc Lemburg).

2c7b8fe618 Fix PR#66. Solution: add error checking around l_divmod() calls in 
long_pow().

42636dc64d Fix for PR#98 (Adrian Eyre) -- in instancemethod_repr, the funcname 
object is DECREFed too early.

4574f23115 PyBuffer_New(): Raise ValueError if size is negative (the other 
constructors didn't miss this).

		 Raise MemoryError if malloc() fails, instead of just
		 returning NULL.

0eb55ac912 Mark Favas was quick to note that the last checkin divides by zero 
when n == 0...  So divide by a->ob_size instead which was already
tested for 0.

fa71701d46 When deallocating a list, DECREF the items from the end back to the start. 1999-06-09 15:19:34 +00:00

98c9eba945 Fix bug discovered by John W. Shipman -- when the width of a format 
specifier came from an int expression instead of a constant in the
format, a negative width was truncated to zero instead of taken to
mean the same as that negative constant plugged into the format.  E.g.
"(%*s)" % (-5, "foo") yielded "(foo)" while "(%-5s)" yields "(foo  )".
Now both yield the latter -- like sprintf() in C.

9263e78ff2 Tim Peters writes: 
1. Fixes float divmod so that the quotient it returns is always an integral
value.

2. Fixes float % and float divmod so that the remainder always gets the
right sign (the current code uses a "are the signs different?" test that
doesn't work half the time <wink> when the product of the divisor and the
remainder underflows to 0).

d7b5fb858c Fix a problem with Vladimir's PyFloat_Fini code: clear the free list; if 
a block cannot be freed, add its free items back to the free list.
This is necessary to avoid leaking when Python is reinitialized later.

51288bce48 Fix a problem with Vladimir's PyInt_Fini code: clear the free list; if 
a block cannot be freed, add its free items back to the free list, and
add its valid ints back to the small_ints array if they are in range.
This is necessary to avoid leaking when Python is reinitialized later.

negative size for PyBuffer_FromMemory.  Greg Stein.

3fce883922 Vladimir has restructured his code somewhat so that the blocks are now 
represented by an explicit structure.  (There are still too many casts
in the code, but that may be unavoidable.)

Also added code so that with -vv it is very chatty about what it does.

f61bbc8182 OK, try again. Vladimir gave me a fix for the alignment bus error, 
so here's his patch again.  This time it works (at least on Solaris,
Linux and Irix).
 1999-03-12 00:12:21 +00:00

a060fb2598 Alas, Vladimir's patch caused a bus error (probably double 
alignment?), and I didn't test it.  Withdrawing it for now.

b5cebfe164 PyLong_FromString(): Nailed a small memory leak. In the str==start 
test, we forgot that z is still pointing to a real live object.
DECREF() it before returning.

3bbef60990 Ai! complex_nonzero() has && which should be ||, else decidedly 
non-zero things like 5j and complex(1,0) are considered to be
zero/false.  Tim Peters.

3aa23fdd47 Jim Ahlstrom patch: cutoff should be a long for machines with 16-bit 
ints.  (In theory, other variables should be widened to long as well,
but this won't ever be needed, since the len of a list is still an
int.)

88303194a5 Fix two places (seek and truncate) where a cascade of PyArg_Parse

cada2938f7 As noted by Per Cederqvist, new_buffersize() sometimes returns the 
buffer increment, and sometimes the new buffer size.  Make it do what
its name says, and fix the one place where this matters to the caller.

Also add a comment explaining why we call lseek() and then ftell().
