Added wrapping macros to dictobject.c, listobject.c, tupleobject.c,
frameobject.c, traceback.c that safely prevends core dumps
on stack overflow. Macros and functions in object.c, object.h.
The method is an "elevator destructor" that turns cascading
deletes into tail recursive behavior when some limit is hit.
diagnostics.
*** INCOMPATIBLE CHANGE: This changes append(), remove(), index(), and
*** count() to require exactly one argument -- previously, multiple
*** arguments were silently assumed to be a tuple.
+ Took the "list" argument out of the other functions that no longer need
it. This speeds things up a little more.
+ Small comment changes in accord with that.
+ Exploited the now-safe ability to cache values in the partitioning loop.
Makes no timing difference on my flavor of Pentium, but this machine ran out
of registers 12 iterations ago. It should yield a small speedup on a RISC
machine, and not hurt in any case.
instead of testing whether the list changed size after each
comparison, temporarily set the type of the list to an immutable list
type. This should allow continued use of the list for legitimate
purposes but disallows all operations that can change it in any way.
(Changes to the internals of list items are not caught, of cause;
that's not possible to detect, and it's not necessary to protect the
sort code, either.)
object pointers. Should be a bit faster than the C library's qsort(),
and doesn't have the prohibition on recursion that Solaris qsort() has
in the threaded version of their C library.
Thanks to discussions with Tim Peters.
* {tuple,list,mapping,array}object.c: call printobject with 0 for flags
* compile.c (parsestr): use quote instead of '\'' at one crucial point
* arraymodule.c (array_getattr): Added __members__ attribute
setlistslice() can be used to cut the unused part out of a freshly made
slice (as done by bagof()). [needed by the next mod!]
* structural changes to bagof(), map() etc.
image objects, and lots of new methods.
* Added counting of allocations and deallocations of builtin types if
COUNT_ALLOCS is defined. Had to move calls to NEWREF down in some
files.
* Bug fix in sorting lists.
Added $(SYSDEF) to its build rule in Makefile.
* cgensupport.[ch], modsupport.[ch]: removed some old stuff. Also
changed files that still used it... And made several things static
that weren't but should have been... And other minor cleanups...
* listobject.[ch]: add external interfaces {set,get}listslice
* socketmodule.c: fix bugs in new send() argument parsing.
* sunaudiodevmodule.c: added flush() and close().
listfontnames, bitmap ops.
* listobject.c: use mkvalue() when possible; avoid weird error when
calling append() without args.
* modsupport.c: new feature in getargs(): if the format string
contains a semicolor the string after that is used as the error
message instead of "bad argument list (format %s)" when there's an
error.
