/* An object allocator for Python.

Here is an introduction to the layers of the Python memory architecture,
|
|
|
|
showing where the object allocator is actually used (layer +2), It is
|
|
|
|
called for every object allocation and deallocation (PyObject_New/Del),
|
|
|
|
unless the object-specific allocators implement a proprietary allocation
|
|
|
|
scheme (ex.: ints use a simple free list). This is also the place where
|
|
|
|
the cyclic garbage collector operates selectively on container objects.

|
* Allocation strategy abstract:
|
|
|
|
*
|
|
|
|
* For small requests, the allocator sub-allocates <Big> blocks of memory.
|
|
|
|
* Requests greater than SMALL_REQUEST_THRESHOLD bytes are routed to the
|
|
|
|
* system's allocator.
|
|
|
|
*
|
|
|
|
* Small requests are grouped in size classes spaced 8 bytes apart, due
|
|
|
|
* to the required valid alignment of the returned address. Requests of
|
|
|
|
* a particular size are serviced from memory pools of 4K (one VMM page).
|
|
|
|
* Pools are fragmented on demand and contain free lists of blocks of one
|
|
|
|
* particular size class. In other words, there is a fixed-size allocator
|
|
|
|
* for each size class. Free pools are shared by the different allocators
|
|
|
|
* thus minimizing the space reserved for a particular size class.
|
|
|
|
*
|
|
|
|
* This allocation strategy is a variant of what is known as "simple
|
|
|
|
* segregated storage based on array of free lists". The main drawback of
|
|
|
|
* simple segregated storage is that we might end up with lot of reserved
|
|
|
|
* memory for the different free lists, which degenerate in time. To avoid
|
|
|
|
* this, we partition each free list in pools and we share dynamically the
|
|
|
|
* reserved space between all free lists. This technique is quite efficient
|
|
|
|
* for memory intensive programs which allocate mainly small-sized blocks.
|
|
|
|
*
|
|
|
|
* For small requests we have the following table:
|
|
|
|
*
|
|
|
|
* Request in bytes Size of allocated block Size class idx

* Pool table -- headed, circular, doubly-linked lists of partially used pools.
|
|
|
|
|
|
|
|
This is involved. For an index i, usedpools[i+i] is the header for a list of
|
|
|
|
all partially used pools holding small blocks with "size class idx" i. So
|
|
|
|
usedpools[0] corresponds to blocks of size 8, usedpools[2] to blocks of size
|
|
|
|
16, and so on: index 2*i <-> blocks of size (i+1)<<ALIGNMENT_SHIFT.
|
|
|
|
|
|
|
|
Pools are carved off an arena's highwater mark (an arena_object's pool_address
|
|
|
|
member) as needed. Once carved off, a pool is in one of three states forever
|
|
|
|
after:
|
|
|
|
|
|
|
|
used == partially used, neither empty nor full
|
|
|
|
At least one block in the pool is currently allocated, and at least one
|
|
|
|
block in the pool is not currently allocated (note this implies a pool
|
|
|
|
has room for at least two blocks).
|
|
|
|
This is a pool's initial state, as a pool is created only when malloc
|
|
|
|
needs space.
|
|
|
|
The pool holds blocks of a fixed size, and is in the circular list headed
|
|
|
|
at usedpools[i] (see above). It's linked to the other used pools of the
|
|
|
|
same size class via the pool_header's nextpool and prevpool members.
|
|
|
|
If all but one block is currently allocated, a malloc can cause a
|
|
|
|
transition to the full state. If all but one block is not currently
|
|
|
|
allocated, a free can cause a transition to the empty state.
|
|
|
|
|
|
|
|
full == all the pool's blocks are currently allocated
|
|
|
|
On transition to full, a pool is unlinked from its usedpools[] list.
|
|
|
|
It's not linked to from anything then anymore, and its nextpool and
|
|
|
|
prevpool members are meaningless until it transitions back to used.
|
|
|
|
A free of a block in a full pool puts the pool back in the used state.
|
|
|
|
Then it's linked in at the front of the appropriate usedpools[] list, so
|
|
|
|
that the next allocation for its size class will reuse the freed block.
|
|
|
|
|
|
|
|
empty == all the pool's blocks are currently available for allocation
|
|
|
|
On transition to empty, a pool is unlinked from its usedpools[] list,
|
|
|
|
and linked to the front of its arena_object's singly-linked freepools list,
|
|
|
|
via its nextpool member. The prevpool member has no meaning in this case.
|
|
|
|
Empty pools have no inherent size class: the next time a malloc finds
|
|
|
|
an empty list in usedpools[], it takes the first pool off of freepools.
|
|
|
|
If the size class needed happens to be the same as the size class the pool
|
|
|
|
last had, some pool initialization can be skipped.
|
|
|
|
|
|
|
|
|
|
|
|
Block Management
|
|
|
|
|
|
|
|
Blocks within pools are again carved out as needed. pool->freeblock points to
|
|
|
|
the start of a singly-linked list of free blocks within the pool. When a
|
|
|
|
block is freed, it's inserted at the front of its pool's freeblock list. Note
|
|
|
|
that the available blocks in a pool are *not* linked all together when a pool
|
|
|
|
is initialized. Instead only "the first two" (lowest addresses) blocks are
|
|
|
|
set up, returning the first such block, and setting pool->freeblock to a
|
|
|
|
one-block list holding the second such block. This is consistent with that
|
|
|
|
pymalloc strives at all levels (arena, pool, and block) never to touch a piece
|
|
|
|
of memory until it's actually needed.
|
|
|
|
|
|
|
|
So long as a pool is in the used state, we're certain there *is* a block
|
|
|
|
available for allocating, and pool->freeblock is not NULL. If pool->freeblock
|
|
|
|
points to the end of the free list before we've carved the entire pool into
|
|
|
|
blocks, that means we simply haven't yet gotten to one of the higher-address
|
|
|
|
blocks. The offset from the pool_header to the start of "the next" virgin
|
|
|
|
block is stored in the pool_header nextoffset member, and the largest value
|
|
|
|
of nextoffset that makes sense is stored in the maxnextoffset member when a
|
|
|
|
pool is initialized. All the blocks in a pool have been passed out at least
|
|
|
|
once when and only when nextoffset > maxnextoffset.
|
|
|
|
|
|
|
|
|
|
|
|
Major obscurity: While the usedpools vector is declared to have poolp
|
|
|
|
entries, it doesn't really. It really contains two pointers per (conceptual)
|
|
|
|
poolp entry, the nextpool and prevpool members of a pool_header. The
|
|
|
|
excruciating initialization code below fools C so that
|
|
|
|
|
|
|
|
usedpool[i+i]
|
|
|
|
|
|
|
|
"acts like" a genuine poolp, but only so long as you only reference its
|
|
|
|
nextpool and prevpool members. The "- 2*sizeof(block *)" gibberish is
|
|
|
|
compensating for that a pool_header's nextpool and prevpool members
|
|
|
|
immediately follow a pool_header's first two members:
|
|
|
|
|
|
|
|
union { block *_padding;
|
|
|
|
uint count; } ref;
|
|
|
|
block *freeblock;
|
|
|
|
|
|
|
|
each of which consume sizeof(block *) bytes. So what usedpools[i+i] really
|
|
|
|
contains is a fudged-up pointer p such that *if* C believes it's a poolp
|
|
|
|
pointer, then p->nextpool and p->prevpool are both p (meaning that the headed
|
|
|
|
circular list is empty).
|
|
|
|
|
|
|
|
It's unclear why the usedpools setup is so convoluted. It could be to
|
|
|
|
minimize the amount of cache required to hold this heavily-referenced table
|
|
|
|
(which only *needs* the two interpool pointer members of a pool_header). OTOH,
|
|
|
|
referencing code has to remember to "double the index" and doing so isn't
|
|
|
|
free, usedpools[0] isn't a strictly legal pointer, and we're crucially relying
|
|
|
|
on that C doesn't insert any padding anywhere in a pool_header at or before
|
|
|
|
the prevpool member.

Arena management.
|
|
|
|
|
|
|
|
`arenas` is a vector of arena_objects. It contains maxarenas entries, some of
|
|
|
|
which may not be currently used (== they're arena_objects that aren't
|
|
|
|
currently associated with an allocated arena). Note that arenas proper are
|
|
|
|
separately malloc'ed.
|
|
|
|
|
|
|
|
Prior to Python 2.5, arenas were never free()'ed. Starting with Python 2.5,
|
|
|
|
we do try to free() arenas, and use some mild heuristic strategies to increase
|
|
|
|
the likelihood that arenas eventually can be freed.
|
|
|
|
|
|
|
|
unused_arena_objects
|
|
|
|
|
|
|
|
This is a singly-linked list of the arena_objects that are currently not
|
|
|
|
being used (no arena is associated with them). Objects are taken off the
|
|
|
|
head of the list in new_arena(), and are pushed on the head of the list in
|
|
|
|
PyObject_Free() when the arena is empty. Key invariant: an arena_object
|
|
|
|
is on this list if and only if its .address member is 0.
|
|
|
|
|
|
|
|
usable_arenas
|
|
|
|
|
|
|
|
This is a doubly-linked list of the arena_objects associated with arenas
|
|
|
|
that have pools available. These pools are either waiting to be reused,
|
|
|
|
or have not been used before. The list is sorted to have the most-
|
|
|
|
allocated arenas first (ascending order based on the nfreepools member).
|
|
|
|
This means that the next allocation will come from a heavily used arena,
|
|
|
|
which gives the nearly empty arenas a chance to be returned to the system.
|
|
|
|
In my unscientific tests this dramatically improved the number of arenas
|
|
|
|
that could be freed.
|
|
|
|
|
|
|
|
Note that an arena_object associated with an arena all of whose pools are
|
|
|
|
currently in use isn't on either list.
|
2019-06-01 10:16:04 +08:00
|
|
|
|
|
|
|
Changed in Python 3.8: keeping usable_arenas sorted by number of free pools
|
|
|
|
used to be done by one-at-a-time linear search when an arena's number of
|
|
|
|
free pools changed. That could, overall, consume time quadratic in the
|
|
|
|
number of arenas. That didn't really matter when there were only a few
|
|
|
|
hundred arenas (typical!), but could be a timing disaster when there were
|
|
|
|
hundreds of thousands. See bpo-37029.
|
|
|
|
|
|
|
|
Now we have a vector of "search fingers" to eliminate the need to search:
|
|
|
|
nfp2lasta[nfp] returns the last ("rightmost") arena in usable_arenas
|
|
|
|
with nfp free pools. This is NULL if and only if there is no arena with
|
|
|
|
nfp free pools in usable_arenas.

Lots of changes:
+ A new scheme for determining whether an address belongs to a pymalloc
arena. This should be 100% reliable. The poolp->pooladdr and
poolp->magic members are gone. A new poolp->arenaindex member takes
their place. Note that the pool header overhead doesn't actually
shrink, though, since the header is padded to a multiple of 8 bytes.
+ _PyMalloc_Free and _PyMalloc_Realloc should now be safe to call for
any legit address, whether obtained from a _PyMalloc function or from
the system malloc/realloc. It should even be safe to call
_PyMalloc_Free when *not* holding the GIL, provided that the passed-in
address was obtained from system malloc/realloc. Since this is
accomplished without any locks, you better believe the code is subtle.
I hope it's sufficiently commented.
+ The above implies we don't need the new PyMalloc_{New, NewVar, Del}
API anymore, and could switch back to PyObject_XXX without breaking
existing code mixing PyObject_XXX with PyMem_{Del, DEL, Free, FREE}.
Nothing is done here about that yet, and I'd like to see this new
code exercised more first.
+ The small object threshhold is boosted to 256 (the max). We should
play with that some more, but the old 64 was way too small for 2.3.
+ Getting a new arena is now done via new function new_arena().
+ Removed some unused macros, and squashed out some macros that were
used only once to define other macros.
+ Arenas are no longer linked together. A new vector of arena base
addresses had to be created anyway to make address classification
bulletproof.
+ A lot of the patch size is an illusion: given the way address
classification works now, it was more convenient to switch the
sense of the prime "if" tests in the realloc and free functions,
so the "if" and "else" blocks got swapped.
+ Assorted minor code, comment and whitespace cleanup.
Back to the Windows installer <wink>.

their place. Note that the pool header overhead doesn't actually
shrink, though, since the header is padded to a multiple of 8 bytes.
+ _PyMalloc_Free and _PyMalloc_Realloc should now be safe to call for
any legit address, whether obtained from a _PyMalloc function or from
the system malloc/realloc. It should even be safe to call
_PyMalloc_Free when *not* holding the GIL, provided that the passed-in
address was obtained from system malloc/realloc. Since this is
accomplished without any locks, you better believe the code is subtle.
I hope it's sufficiently commented.
+ The above implies we don't need the new PyMalloc_{New, NewVar, Del}
API anymore, and could switch back to PyObject_XXX without breaking
existing code mixing PyObject_XXX with PyMem_{Del, DEL, Free, FREE}.
Nothing is done here about that yet, and I'd like to see this new
code exercised more first.
+ The small object threshhold is boosted to 256 (the max). We should
play with that some more, but the old 64 was way too small for 2.3.

Return true if and only if P is an address that was allocated by pymalloc.
|
|
|
|
POOL must be the pool address associated with P, i.e., POOL = POOL_ADDR(P)
|
|
|
|
(the caller is asked to compute this because the macro expands POOL more than
|
|
|
|
once, and for efficiency it's best for the caller to assign POOL_ADDR(P) to a
|
2016-09-19 10:12:48 +08:00
|
|
|
variable and pass the latter to the macro; because address_in_range is
|
2006-04-21 17:43:23 +08:00
|
|
|
called on every alloc/realloc/free, micro-efficiency is important here).
|
|
|
|
|
|
|
|
Tricky: Let B be the arena base address associated with the pool, B =
|
|
|
|
arenas[(POOL)->arenaindex].address. Then P belongs to the arena if and only if
|
|
|
|
|
2010-05-09 23:52:27 +08:00
|
|
|
B <= P < B + ARENA_SIZE
|
2006-04-21 17:43:23 +08:00
|
|
|
|
|
|
|
Subtracting B throughout, this is true iff
|
|
|
|
|
2010-05-09 23:52:27 +08:00
|
|
|
0 <= P-B < ARENA_SIZE
|
2006-04-21 17:43:23 +08:00
|
|
|
|
|
|
|
By using unsigned arithmetic, the "0 <=" half of the test can be skipped.
|
|
|
|
|
|
|
|
Obscure: A PyMem "free memory" function can call the pymalloc free or realloc
|
|
|
|
before the first arena has been allocated. `arenas` is still NULL in that
|
|
|
|
case. We're relying on that maxarenas is also 0 in that case, so that
|
|
|
|
(POOL)->arenaindex < maxarenas must be false, saving us from trying to index
|
|
|
|
into a NULL arenas.
|
|
|
|
|
|
|
|
Details: given P and POOL, the arena_object corresponding to P is AO =
|
|
|
|
arenas[(POOL)->arenaindex]. Suppose obmalloc controls P. Then (barring wild
|
|
|
|
stores, etc), POOL is the correct address of P's pool, AO.address is the
|
|
|
|
correct base address of the pool's arena, and P must be within ARENA_SIZE of
|
|
|
|
AO.address. In addition, AO.address is not 0 (no arena can start at address 0
|
2016-09-19 10:12:48 +08:00
|
|
|
(NULL)). Therefore address_in_range correctly reports that obmalloc
|
2006-04-21 17:43:23 +08:00
|
|
|
controls P.
|
|
|
|
|
|
|
|
Now suppose obmalloc does not control P (e.g., P was obtained via a direct
|
|
|
|
call to the system malloc() or realloc()). (POOL)->arenaindex may be anything
|
|
|
|
in this case -- it may even be uninitialized trash. If the trash arenaindex
|
|
|
|
is >= maxarenas, the macro correctly concludes at once that obmalloc doesn't
|
|
|
|
control P.
|
|
|
|
|
|
|
|
Else arenaindex is < maxarena, and AO is read up. If AO corresponds to an
|
|
|
|
allocated arena, obmalloc controls all the memory in slice AO.address :
|
|
|
|
AO.address+ARENA_SIZE. By case assumption, P is not controlled by obmalloc,
|
|
|
|
so P doesn't lie in that slice, so the macro correctly reports that P is not
|
|
|
|
controlled by obmalloc.
|
|
|
|
|
|
|
|
Finally, if P is not controlled by obmalloc and AO corresponds to an unused
|
|
|
|
arena_object (one not currently associated with an allocated arena),
|
|
|
|
AO.address is 0, and the second test in the macro reduces to:
|
|
|
|
|
2010-05-09 23:52:27 +08:00
|
|
|
P < ARENA_SIZE
|
2006-04-21 17:43:23 +08:00
|
|
|
|
|
|
|
If P >= ARENA_SIZE (extremely likely), the macro again correctly concludes
|
|
|
|
that P is not controlled by obmalloc. However, if P < ARENA_SIZE, this part
|
|
|
|
of the test still passes, and the third clause (AO.address != 0) is necessary
|
|
|
|
to get the correct result: AO.address is 0 in this case, so the macro
|
|
|
|
correctly reports that P is not controlled by obmalloc (despite that P lies in
|
|
|
|
slice AO.address : AO.address + ARENA_SIZE).
|
|
|
|
|
|
|
|
Note: The third (AO.address != 0) clause was added in Python 2.5. Before
|
|
|
|
2.5, arenas were never free()'ed, and an arenaindex < maxarena always
|
|
|
|
corresponded to a currently-allocated arena, so the "P is not controlled by
|
|
|
|
obmalloc, AO corresponds to an unused arena_object, and P < ARENA_SIZE" case
|
|
|
|
was impossible.
|
|
|
|
|
|
|
|
Note that the logic is excruciating, and reading up possibly uninitialized
|
|
|
|
memory when P is not controlled by obmalloc (to get at (POOL)->arenaindex)
|
|
|
|
creates problems for some memory debuggers. The overwhelming advantage is
|
|
|
|
that this test determines whether an arbitrary address is controlled by
|
|
|
|
obmalloc in a small constant time, independent of the number of arenas
|
|
|
|
obmalloc controls. Since this test is needed at every entry point, it's
|
|
|
|
extremely desirable that it be this fast.

Lots of changes:
+ A new scheme for determining whether an address belongs to a pymalloc
arena. This should be 100% reliable. The poolp->pooladdr and
poolp->magic members are gone. A new poolp->arenaindex member takes
their place. Note that the pool header overhead doesn't actually
shrink, though, since the header is padded to a multiple of 8 bytes.
+ _PyMalloc_Free and _PyMalloc_Realloc should now be safe to call for
any legit address, whether obtained from a _PyMalloc function or from
the system malloc/realloc. It should even be safe to call
_PyMalloc_Free when *not* holding the GIL, provided that the passed-in
address was obtained from system malloc/realloc. Since this is
accomplished without any locks, you better believe the code is subtle.
I hope it's sufficiently commented.
+ The above implies we don't need the new PyMalloc_{New, NewVar, Del}
API anymore, and could switch back to PyObject_XXX without breaking
existing code mixing PyObject_XXX with PyMem_{Del, DEL, Free, FREE}.
Nothing is done here about that yet, and I'd like to see this new
code exercised more first.
+ The small object threshhold is boosted to 256 (the max). We should
play with that some more, but the old 64 was way too small for 2.3.
+ Getting a new arena is now done via new function new_arena().
+ Removed some unused macros, and squashed out some macros that were
used only once to define other macros.
+ Arenas are no longer linked together. A new vector of arena base
addresses had to be created anyway to make address classification
bulletproof.
+ A lot of the patch size is an illusion: given the way address
classification works now, it was more convenient to switch the
sense of the prime "if" tests in the realloc and free functions,
so the "if" and "else" blocks got swapped.
+ Assorted minor code, comment and whitespace cleanup.
Back to the Windows installer <wink>.

Give Python a debug-mode pymalloc, much as sketched on Python-Dev.
When WITH_PYMALLOC is defined, define PYMALLOC_DEBUG to enable the debug
allocator. This can be done independent of build type (release or debug).
A debug build automatically defines PYMALLOC_DEBUG when pymalloc is
enabled. It's a detected error to define PYMALLOC_DEBUG when pymalloc
isn't enabled.
Two debugging entry points defined only under PYMALLOC_DEBUG:
+ _PyMalloc_DebugCheckAddress(const void *p) can be used (e.g., from gdb)
to sanity-check a memory block obtained from pymalloc. It sprays
info to stderr (see next) and dies via Py_FatalError if the block is
detectably damaged.
+ _PyMalloc_DebugDumpAddress(const void *p) can be used to spray info
about a debug memory block to stderr.
A tiny start at implementing "API family" checks isn't good for
anything yet.
_PyMalloc_DebugRealloc() has been optimized to do little when the new
size is <= old size. However, if the new size is larger, it really
can't call the underlying realloc() routine without either violating its
contract, or knowing something non-trivial about how the underlying
realloc() works. A memcpy is always done in this case.
This was a disaster for (and only) one of the std tests: test_bufio
creates single text file lines up to a million characters long. On
Windows, fileobject.c's get_line() uses the horridly funky
getline_via_fgets(), which keeps growing and growing a string object
hoping to find a newline. It grew the string object 1000 bytes each
time, so for a million-character string it took approximately forever
(I gave up after a few minutes).
So, also:
fileobject.c, getline_via_fgets(): When a single line is outrageously
long, grow the string object at a mildly exponential rate, instead of
just 1000 bytes at a time.
That's enough so that a debug-build test_bufio finishes in about 5 seconds
on my Win98SE box. I'm curious to try this on Win2K, because it has very
different memory behavior than Win9X, and test_bufio always took a factor
of 10 longer to complete on Win2K. It *could* be that the endless
reallocs were simply killing it on Win2K even in the release build.

In a PYMALLOC_DEBUG build obmalloc adds extra debugging info
to each allocated block. This was using 4 bytes for each such
piece of info regardless of platform. This didn't really matter
before (proof: no bug reports, and the debug-build obmalloc would
have assert-failed if it was ever asked for a chunk of memory
>= 2**32 bytes), since container indices were plain ints. But after
the Py_ssize_t changes, it's at least theoretically possible to
allocate a list or string whose guts exceed 2**32 bytes, and the
PYMALLOC_DEBUG routines would fail then (having only 4 bytes
to record the originally requested size).
Now we use sizeof(size_t) bytes for each of a PYMALLOC_DEBUG
build's extra debugging fields. This won't make any difference
on 32-bit boxes, but will add 16 bytes to each allocation in
a debug build on a 64-bit box.

- Made fixes to _struct.c according to Neal Norwitz comments on the checkins
list.
- Converted some ints into the appropriate -- I hope -- ssize_t and size_t.

The first is causing many buildbots to fail test runs, and there
are multiple causes with seemingly no immediate prospects for
repairing them. See python-dev discussion.
Note that a branch can (and should) be created for resolving these
problems, like
svn copy svn+ssh://svn.python.org/python/trunk -r46640 svn+ssh://svn.python.org/python/branches/NEW_BRANCH
followed by merging rev 46647 to the new branch.

_PySys_Init(): It's rarely a good idea to size a buffer to the
exact maximum size someone guesses is needed. In this case, if
we're really worried about extreme integers, then "cp%d" can
actually need 14 bytes (2 for "cp" + 1 for \0 at the end +
11 for -(2**31-1)). So reserve 128 bytes instead -- nothing is
actually saved by making a stack-local buffer tiny.

SF patch 1501987: Remove randomness from test_exceptions,
from ?iga Seilnacht (sorry about the name, but Firefox
on my box can't display the first character of the name --
the SF "Unix name" is zseil).
This appears to cure the oddball intermittent leaks across
runs when running test_exceptions under -R. I'm not sure
why, but I'm too sleepy to care ;-)
The thrust of the SF patch was to remove randomness in the
pickle protocol used. I changed the patch to use
range(pickle.HIGHEST_PROTOCOL + 1), to try both pickle and
cPickle, and randomly mucked with other test lines to put
statements on their own lines.
Not a bugfix candidate (this is fiddling new-in-2.5 code).

[Bug #1497414] _self is a reserved word in the WATCOM 10.6 C compiler.
Fix by renaming the variable.
In a different module, Neal fixed it by renaming _self to self. There's
already a variable named 'self' here, so I used selfptr.
(I'm committing this on a Mac without Tk, but it's a simple search-and-replace.
<crosses fingers>, so I'll watch the buildbots and see what happens.)

In a PYMALLOC_DEBUG build obmalloc adds extra debugging info
to each allocated block. This was using 4 bytes for each such
piece of info regardless of platform. This didn't really matter
before (proof: no bug reports, and the debug-build obmalloc would
have assert-failed if it was ever asked for a chunk of memory
>= 2**32 bytes), since container indices were plain ints. But after
the Py_ssize_t changes, it's at least theoretically possible to
allocate a list or string whose guts exceed 2**32 bytes, and the
PYMALLOC_DEBUG routines would fail then (having only 4 bytes
to record the originally requested size).
Now we use sizeof(size_t) bytes for each of a PYMALLOC_DEBUG
build's extra debugging fields. This won't make any difference
on 32-bit boxes, but will add 16 bytes to each allocation in
a debug build on a 64-bit box.

The first is causing many buildbots to fail test runs, and there
are multiple causes with seemingly no immediate prospects for
repairing them. See python-dev discussion.
Note that a branch can (and should) be created for resolving these
problems, like

followed by merging rev 46647 to the new branch.

_PySys_Init(): It's rarely a good idea to size a buffer to the
exact maximum size someone guesses is needed. In this case, if
we're really worried about extreme integers, then "cp%d" can
actually need 14 bytes (2 for "cp" + 1 for \0 at the end +
11 for -(2**31-1)). So reserve 128 bytes instead -- nothing is
actually saved by making a stack-local buffer tiny.

SF patch 1501987: Remove randomness from test_exceptions,
from ?iga Seilnacht (sorry about the name, but Firefox
on my box can't display the first character of the name --
the SF "Unix name" is zseil).
This appears to cure the oddball intermittent leaks across
runs when running test_exceptions under -R. I'm not sure
why, but I'm too sleepy to care ;-)
The thrust of the SF patch was to remove randomness in the
pickle protocol used. I changed the patch to use
range(pickle.HIGHEST_PROTOCOL + 1), to try both pickle and
cPickle, and randomly mucked with other test lines to put
statements on their own lines.
Not a bugfix candidate (this is fiddling new-in-2.5 code).

[Bug #1497414] _self is a reserved word in the WATCOM 10.6 C compiler.
Fix by renaming the variable.
In a different module, Neal fixed it by renaming _self to self. There's
already a variable named 'self' here, so I used selfptr.
(I'm committing this on a Mac without Tk, but it's a simple search-and-replace.
<crosses fingers>, so I'll watch the buildbots and see what happens.)

In a PYMALLOC_DEBUG build obmalloc adds extra debugging info
to each allocated block. This was using 4 bytes for each such
piece of info regardless of platform. This didn't really matter
before (proof: no bug reports, and the debug-build obmalloc would
have assert-failed if it was ever asked for a chunk of memory
>= 2**32 bytes), since container indices were plain ints. But after
the Py_ssize_t changes, it's at least theoretically possible to
allocate a list or string whose guts exceed 2**32 bytes, and the
PYMALLOC_DEBUG routines would fail then (having only 4 bytes
to record the originally requested size).
Now we use sizeof(size_t) bytes for each of a PYMALLOC_DEBUG
build's extra debugging fields. This won't make any difference
on 32-bit boxes, but will add 16 bytes to each allocation in
a debug build on a 64-bit box.

The first is causing many buildbots to fail test runs, and there
are multiple causes with seemingly no immediate prospects for
repairing them. See python-dev discussion.
Note that a branch can (and should) be created for resolving these

_PySys_Init(): It's rarely a good idea to size a buffer to the
exact maximum size someone guesses is needed. In this case, if
we're really worried about extreme integers, then "cp%d" can
actually need 14 bytes (2 for "cp" + 1 for \0 at the end +
11 for -(2**31-1)). So reserve 128 bytes instead -- nothing is
actually saved by making a stack-local buffer tiny.

SF patch 1501987: Remove randomness from test_exceptions,
from ?iga Seilnacht (sorry about the name, but Firefox
on my box can't display the first character of the name --
the SF "Unix name" is zseil).
This appears to cure the oddball intermittent leaks across
runs when running test_exceptions under -R. I'm not sure
why, but I'm too sleepy to care ;-)
The thrust of the SF patch was to remove randomness in the
pickle protocol used. I changed the patch to use
range(pickle.HIGHEST_PROTOCOL + 1), to try both pickle and
cPickle, and randomly mucked with other test lines to put
statements on their own lines.
Not a bugfix candidate (this is fiddling new-in-2.5 code).

Give Python a debug-mode pymalloc, much as sketched on Python-Dev.
When WITH_PYMALLOC is defined, define PYMALLOC_DEBUG to enable the debug
allocator. This can be done independent of build type (release or debug).
A debug build automatically defines PYMALLOC_DEBUG when pymalloc is
enabled. It's a detected error to define PYMALLOC_DEBUG when pymalloc
isn't enabled.
Two debugging entry points defined only under PYMALLOC_DEBUG:
+ _PyMalloc_DebugCheckAddress(const void *p) can be used (e.g., from gdb)
to sanity-check a memory block obtained from pymalloc. It sprays
info to stderr (see next) and dies via Py_FatalError if the block is
detectably damaged.
+ _PyMalloc_DebugDumpAddress(const void *p) can be used to spray info
about a debug memory block to stderr.
A tiny start at implementing "API family" checks isn't good for
anything yet.
_PyMalloc_DebugRealloc() has been optimized to do little when the new
size is <= old size. However, if the new size is larger, it really
can't call the underlying realloc() routine without either violating its
contract, or knowing something non-trivial about how the underlying
realloc() works. A memcpy is always done in this case.
This was a disaster for (and only) one of the std tests: test_bufio
creates single text file lines up to a million characters long. On
Windows, fileobject.c's get_line() uses the horridly funky
getline_via_fgets(), which keeps growing and growing a string object
hoping to find a newline. It grew the string object 1000 bytes each
time, so for a million-character string it took approximately forever
(I gave up after a few minutes).
So, also:
fileobject.c, getline_via_fgets(): When a single line is outrageously
long, grow the string object at a mildly exponential rate, instead of
just 1000 bytes at a time.
That's enough so that a debug-build test_bufio finishes in about 5 seconds
on my Win98SE box. I'm curious to try this on Win2K, because it has very
different memory behavior than Win9X, and test_bufio always took a factor
of 10 longer to complete on Win2K. It *could* be that the endless
reallocs were simply killing it on Win2K even in the release build.

In a PYMALLOC_DEBUG build obmalloc adds extra debugging info
to each allocated block. This was using 4 bytes for each such
piece of info regardless of platform. This didn't really matter
before (proof: no bug reports, and the debug-build obmalloc would
have assert-failed if it was ever asked for a chunk of memory
>= 2**32 bytes), since container indices were plain ints. But after
the Py_ssize_t changes, it's at least theoretically possible to
allocate a list or string whose guts exceed 2**32 bytes, and the
PYMALLOC_DEBUG routines would fail then (having only 4 bytes
to record the originally requested size).
Now we use sizeof(size_t) bytes for each of a PYMALLOC_DEBUG
build's extra debugging fields. This won't make any difference
on 32-bit boxes, but will add 16 bytes to each allocation in
a debug build on a 64-bit box.

46640 Patch #1454481: Make thread stack size runtime tunable.
46647 Markup fix
The first is causing many buildbots to fail test runs, and there
are multiple causes with seemingly no immediate prospects for
repairing them. See python-dev discussion.
Note that a branch can (and should) be created for resolving these
problems, like
svn copy svn+ssh://svn.python.org/python/trunk -r46640 svn+ssh://svn.python.org/python/branches/NEW_BRANCH
followed by merging rev 46647 to the new branch.

"Flat is better than nested."
Move the long-winded, multiply-nested -R support out
of runtest() and into some module-level helper functions.
This makes runtest() and the -R code easier to follow.
That in turn allowed seeing some opportunities for code
simplification, and made it obvious that reglog.txt
never got closed.

_PySys_Init(): It's rarely a good idea to size a buffer to the
exact maximum size someone guesses is needed. In this case, if
we're really worried about extreme integers, then "cp%d" can
actually need 14 bytes (2 for "cp" + 1 for \0 at the end +
11 for -(2**31-1)). So reserve 128 bytes instead -- nothing is
actually saved by making a stack-local buffer tiny.

SF patch 1501987: Remove randomness from test_exceptions,
from ?iga Seilnacht (sorry about the name, but Firefox
on my box can't display the first character of the name --
the SF "Unix name" is zseil).
This appears to cure the oddball intermittent leaks across
runs when running test_exceptions under -R. I'm not sure
why, but I'm too sleepy to care ;-)
The thrust of the SF patch was to remove randomness in the
pickle protocol used. I changed the patch to use
range(pickle.HIGHEST_PROTOCOL + 1), to try both pickle and
cPickle, and randomly mucked with other test lines to put
statements on their own lines.
Not a bugfix candidate (this is fiddling new-in-2.5 code).

Give Python a debug-mode pymalloc, much as sketched on Python-Dev.
When WITH_PYMALLOC is defined, define PYMALLOC_DEBUG to enable the debug
allocator. This can be done independent of build type (release or debug).
A debug build automatically defines PYMALLOC_DEBUG when pymalloc is
enabled. It's a detected error to define PYMALLOC_DEBUG when pymalloc
isn't enabled.
Two debugging entry points defined only under PYMALLOC_DEBUG:
+ _PyMalloc_DebugCheckAddress(const void *p) can be used (e.g., from gdb)
to sanity-check a memory block obtained from pymalloc. It sprays
info to stderr (see next) and dies via Py_FatalError if the block is
detectably damaged.
+ _PyMalloc_DebugDumpAddress(const void *p) can be used to spray info
about a debug memory block to stderr.
A tiny start at implementing "API family" checks isn't good for
anything yet.
_PyMalloc_DebugRealloc() has been optimized to do little when the new
size is <= old size. However, if the new size is larger, it really
can't call the underlying realloc() routine without either violating its
contract, or knowing something non-trivial about how the underlying
realloc() works. A memcpy is always done in this case.
This was a disaster for (and only) one of the std tests: test_bufio
creates single text file lines up to a million characters long. On
Windows, fileobject.c's get_line() uses the horridly funky
getline_via_fgets(), which keeps growing and growing a string object
hoping to find a newline. It grew the string object 1000 bytes each
time, so for a million-character string it took approximately forever
(I gave up after a few minutes).
So, also:
fileobject.c, getline_via_fgets(): When a single line is outrageously
long, grow the string object at a mildly exponential rate, instead of
just 1000 bytes at a time.
That's enough so that a debug-build test_bufio finishes in about 5 seconds
on my Win98SE box. I'm curious to try this on Win2K, because it has very
different memory behavior than Win9X, and test_bufio always took a factor
of 10 longer to complete on Win2K. It *could* be that the endless
reallocs were simply killing it on Win2K even in the release build.

In a PYMALLOC_DEBUG build obmalloc adds extra debugging info
to each allocated block. This was using 4 bytes for each such
piece of info regardless of platform. This didn't really matter
before (proof: no bug reports, and the debug-build obmalloc would
have assert-failed if it was ever asked for a chunk of memory
>= 2**32 bytes), since container indices were plain ints. But after
the Py_ssize_t changes, it's at least theoretically possible to
allocate a list or string whose guts exceed 2**32 bytes, and the
PYMALLOC_DEBUG routines would fail then (having only 4 bytes
to record the originally requested size).
Now we use sizeof(size_t) bytes for each of a PYMALLOC_DEBUG
build's extra debugging fields. This won't make any difference
on 32-bit boxes, but will add 16 bytes to each allocation in
a debug build on a 64-bit box.

The first is causing many buildbots to fail test runs, and there
are multiple causes with seemingly no immediate prospects for
repairing them. See python-dev discussion.
Note that a branch can (and should) be created for resolving these
problems, like
svn copy svn+ssh://svn.python.org/python/trunk -r46640 svn+ssh://svn.python.org/python/branches/NEW_BRANCH
followed by merging rev 46647 to the new branch.

_PySys_Init(): It's rarely a good idea to size a buffer to the
exact maximum size someone guesses is needed. In this case, if
we're really worried about extreme integers, then "cp%d" can
actually need 14 bytes (2 for "cp" + 1 for \0 at the end +
11 for -(2**31-1)). So reserve 128 bytes instead -- nothing is
actually saved by making a stack-local buffer tiny.

SF patch 1501987: Remove randomness from test_exceptions,
from ?iga Seilnacht (sorry about the name, but Firefox
on my box can't display the first character of the name --
the SF "Unix name" is zseil).
This appears to cure the oddball intermittent leaks across
runs when running test_exceptions under -R. I'm not sure
why, but I'm too sleepy to care ;-)
The thrust of the SF patch was to remove randomness in the
pickle protocol used. I changed the patch to use
range(pickle.HIGHEST_PROTOCOL + 1), to try both pickle and
cPickle, and randomly mucked with other test lines to put
statements on their own lines.
Not a bugfix candidate (this is fiddling new-in-2.5 code).

Give Python a debug-mode pymalloc, much as sketched on Python-Dev.
When WITH_PYMALLOC is defined, define PYMALLOC_DEBUG to enable the debug
allocator. This can be done independent of build type (release or debug).
A debug build automatically defines PYMALLOC_DEBUG when pymalloc is
enabled. It's a detected error to define PYMALLOC_DEBUG when pymalloc
isn't enabled.
Two debugging entry points defined only under PYMALLOC_DEBUG:
+ _PyMalloc_DebugCheckAddress(const void *p) can be used (e.g., from gdb)
to sanity-check a memory block obtained from pymalloc. It sprays
info to stderr (see next) and dies via Py_FatalError if the block is
detectably damaged.
+ _PyMalloc_DebugDumpAddress(const void *p) can be used to spray info
about a debug memory block to stderr.
A tiny start at implementing "API family" checks isn't good for
anything yet.
_PyMalloc_DebugRealloc() has been optimized to do little when the new
size is <= old size. However, if the new size is larger, it really
can't call the underlying realloc() routine without either violating its
contract, or knowing something non-trivial about how the underlying
realloc() works. A memcpy is always done in this case.
This was a disaster for (and only) one of the std tests: test_bufio
creates single text file lines up to a million characters long. On
Windows, fileobject.c's get_line() uses the horridly funky
getline_via_fgets(), which keeps growing and growing a string object
hoping to find a newline. It grew the string object 1000 bytes each
time, so for a million-character string it took approximately forever
(I gave up after a few minutes).
So, also:
fileobject.c, getline_via_fgets(): When a single line is outrageously
long, grow the string object at a mildly exponential rate, instead of
just 1000 bytes at a time.
That's enough so that a debug-build test_bufio finishes in about 5 seconds
on my Win98SE box. I'm curious to try this on Win2K, because it has very
different memory behavior than Win9X, and test_bufio always took a factor
of 10 longer to complete on Win2K. It *could* be that the endless
reallocs were simply killing it on Win2K even in the release build.

Fix by renaming the variable.

In a PYMALLOC_DEBUG build obmalloc adds extra debugging info
to each allocated block. This was using 4 bytes for each such
piece of info regardless of platform. This didn't really matter
before (proof: no bug reports, and the debug-build obmalloc would
have assert-failed if it was ever asked for a chunk of memory
>= 2**32 bytes), since container indices were plain ints. But after
the Py_ssize_t changes, it's at least theoretically possible to
allocate a list or string whose guts exceed 2**32 bytes, and the
PYMALLOC_DEBUG routines would fail then (having only 4 bytes
to record the originally requested size).
Now we use sizeof(size_t) bytes for each of a PYMALLOC_DEBUG
build's extra debugging fields. This won't make any difference
on 32-bit boxes, but will add 16 bytes to each allocation in
a debug build on a 64-bit box.

SF patch 1501987: Remove randomness from test_exceptions,
from ?iga Seilnacht (sorry about the name, but Firefox
on my box can't display the first character of the name --
the SF "Unix name" is zseil).
This appears to cure the oddball intermittent leaks across
runs when running test_exceptions under -R. I'm not sure
why, but I'm too sleepy to care ;-)
The thrust of the SF patch was to remove randomness in the
pickle protocol used. I changed the patch to use
range(pickle.HIGHEST_PROTOCOL + 1), to try both pickle and
cPickle, and randomly mucked with other test lines to put
statements on their own lines.
Not a bugfix candidate (this is fiddling new-in-2.5 code).

write_size_t(void *p, size_t n)
|
Give Python a debug-mode pymalloc, much as sketched on Python-Dev.
When WITH_PYMALLOC is defined, define PYMALLOC_DEBUG to enable the debug
allocator. This can be done independent of build type (release or debug).
A debug build automatically defines PYMALLOC_DEBUG when pymalloc is
enabled. It's a detected error to define PYMALLOC_DEBUG when pymalloc
isn't enabled.
Two debugging entry points defined only under PYMALLOC_DEBUG:
+ _PyMalloc_DebugCheckAddress(const void *p) can be used (e.g., from gdb)
to sanity-check a memory block obtained from pymalloc. It sprays
info to stderr (see next) and dies via Py_FatalError if the block is
detectably damaged.
+ _PyMalloc_DebugDumpAddress(const void *p) can be used to spray info
about a debug memory block to stderr.
A tiny start at implementing "API family" checks isn't good for
anything yet.
_PyMalloc_DebugRealloc() has been optimized to do little when the new
size is <= old size. However, if the new size is larger, it really
can't call the underlying realloc() routine without either violating its
contract, or knowing something non-trivial about how the underlying
realloc() works. A memcpy is always done in this case.
This was a disaster for (and only) one of the std tests: test_bufio
creates single text file lines up to a million characters long. On
Windows, fileobject.c's get_line() uses the horridly funky
getline_via_fgets(), which keeps growing and growing a string object
hoping to find a newline. It grew the string object 1000 bytes each
time, so for a million-character string it took approximately forever
(I gave up after a few minutes).
So, also:
fileobject.c, getline_via_fgets(): When a single line is outrageously
long, grow the string object at a mildly exponential rate, instead of
just 1000 bytes at a time.
That's enough so that a debug-build test_bufio finishes in about 5 seconds
on my Win98SE box. I'm curious to try this on Win2K, because it has very
different memory behavior than Win9X, and test_bufio always took a factor
of 10 longer to complete on Win2K. It *could* be that the endless
reallocs were simply killing it on Win2K even in the release build.

In a PYMALLOC_DEBUG build obmalloc adds extra debugging info
to each allocated block. This was using 4 bytes for each such
piece of info regardless of platform. This didn't really matter
before (proof: no bug reports, and the debug-build obmalloc would
have assert-failed if it was ever asked for a chunk of memory
>= 2**32 bytes), since container indices were plain ints. But after
the Py_ssize_t changes, it's at least theoretically possible to
allocate a list or string whose guts exceed 2**32 bytes, and the
PYMALLOC_DEBUG routines would fail then (having only 4 bytes
to record the originally requested size).
Now we use sizeof(size_t) bytes for each of a PYMALLOC_DEBUG
build's extra debugging fields. This won't make any difference
on 32-bit boxes, but will add 16 bytes to each allocation in
a debug build on a 64-bit box.

are multiple causes with seemingly no immediate prospects for
repairing them. See python-dev discussion.
Note that a branch can (and should) be created for resolving these
problems, like
svn copy svn+ssh://svn.python.org/python/trunk -r46640 svn+ssh://svn.python.org/python/branches/NEW_BRANCH
followed by merging rev 46647 to the new branch.

"Flat is better than nested."
Move the long-winded, multiply-nested -R support out
of runtest() and into some module-level helper functions.
This makes runtest() and the -R code easier to follow.
That in turn allowed seeing some opportunities for code
simplification, and made it obvious that reglog.txt
never got closed.

_PySys_Init(): It's rarely a good idea to size a buffer to the
exact maximum size someone guesses is needed. In this case, if
we're really worried about extreme integers, then "cp%d" can
actually need 14 bytes (2 for "cp" + 1 for \0 at the end +
11 for -(2**31-1)). So reserve 128 bytes instead -- nothing is
actually saved by making a stack-local buffer tiny.

SF patch 1501987: Remove randomness from test_exceptions,
from ?iga Seilnacht (sorry about the name, but Firefox
on my box can't display the first character of the name --
the SF "Unix name" is zseil).
This appears to cure the oddball intermittent leaks across
runs when running test_exceptions under -R. I'm not sure
why, but I'm too sleepy to care ;-)
The thrust of the SF patch was to remove randomness in the
pickle protocol used. I changed the patch to use
range(pickle.HIGHEST_PROTOCOL + 1), to try both pickle and
cPickle, and randomly mucked with other test lines to put
statements on their own lines.
Not a bugfix candidate (this is fiddling new-in-2.5 code).

Give Python a debug-mode pymalloc, much as sketched on Python-Dev.
When WITH_PYMALLOC is defined, define PYMALLOC_DEBUG to enable the debug
allocator. This can be done independent of build type (release or debug).
A debug build automatically defines PYMALLOC_DEBUG when pymalloc is
enabled. It's a detected error to define PYMALLOC_DEBUG when pymalloc
isn't enabled.
Two debugging entry points defined only under PYMALLOC_DEBUG:
+ _PyMalloc_DebugCheckAddress(const void *p) can be used (e.g., from gdb)
to sanity-check a memory block obtained from pymalloc. It sprays
info to stderr (see next) and dies via Py_FatalError if the block is
detectably damaged.
+ _PyMalloc_DebugDumpAddress(const void *p) can be used to spray info
about a debug memory block to stderr.
A tiny start at implementing "API family" checks isn't good for
anything yet.
_PyMalloc_DebugRealloc() has been optimized to do little when the new
size is <= old size. However, if the new size is larger, it really
can't call the underlying realloc() routine without either violating its
contract, or knowing something non-trivial about how the underlying
realloc() works. A memcpy is always done in this case.
This was a disaster for (and only) one of the std tests: test_bufio
creates single text file lines up to a million characters long. On
Windows, fileobject.c's get_line() uses the horridly funky
getline_via_fgets(), which keeps growing and growing a string object
hoping to find a newline. It grew the string object 1000 bytes each
time, so for a million-character string it took approximately forever
(I gave up after a few minutes).
So, also:
fileobject.c, getline_via_fgets(): When a single line is outrageously
long, grow the string object at a mildly exponential rate, instead of
just 1000 bytes at a time.
That's enough so that a debug-build test_bufio finishes in about 5 seconds
on my Win98SE box. I'm curious to try this on Win2K, because it has very
different memory behavior than Win9X, and test_bufio always took a factor
of 10 longer to complete on Win2K. It *could* be that the endless
reallocs were simply killing it on Win2K even in the release build.

already a variable named 'self' here, so I used selfptr.
(I'm committing this on a Mac without Tk, but it's a simple search-and-replace.
<crosses fingers>, so I'll watch the buildbots and see what happens.)

In a PYMALLOC_DEBUG build obmalloc adds extra debugging info
to each allocated block. This was using 4 bytes for each such
piece of info regardless of platform. This didn't really matter
before (proof: no bug reports, and the debug-build obmalloc would
have assert-failed if it was ever asked for a chunk of memory
>= 2**32 bytes), since container indices were plain ints. But after
the Py_ssize_t changes, it's at least theoretically possible to
allocate a list or string whose guts exceed 2**32 bytes, and the
PYMALLOC_DEBUG routines would fail then (having only 4 bytes
to record the originally requested size).
Now we use sizeof(size_t) bytes for each of a PYMALLOC_DEBUG
build's extra debugging fields. This won't make any difference
on 32-bit boxes, but will add 16 bytes to each allocation in
a debug build on a 64-bit box.

The first is causing many buildbots to fail test runs, and there
are multiple causes with seemingly no immediate prospects for
repairing them. See python-dev discussion.
Note that a branch can (and should) be created for resolving these

_PySys_Init(): It's rarely a good idea to size a buffer to the

we're really worried about extreme integers, then "cp%d" can
actually need 14 bytes (2 for "cp" + 1 for \0 at the end +
11 for -(2**31-1)). So reserve 128 bytes instead -- nothing is
actually saved by making a stack-local buffer tiny.

SF patch 1501987: Remove randomness from test_exceptions,
from ?iga Seilnacht (sorry about the name, but Firefox
on my box can't display the first character of the name --
the SF "Unix name" is zseil).
This appears to cure the oddball intermittent leaks across
runs when running test_exceptions under -R. I'm not sure
why, but I'm too sleepy to care ;-)
The thrust of the SF patch was to remove randomness in the
pickle protocol used. I changed the patch to use
range(pickle.HIGHEST_PROTOCOL + 1), to try both pickle and
cPickle, and randomly mucked with other test lines to put
statements on their own lines.
Not a bugfix candidate (this is fiddling new-in-2.5 code).

fills them with useful stuff, here calling the underlying malloc's result p:
|
Give Python a debug-mode pymalloc, much as sketched on Python-Dev.
When WITH_PYMALLOC is defined, define PYMALLOC_DEBUG to enable the debug
allocator. This can be done independent of build type (release or debug).
A debug build automatically defines PYMALLOC_DEBUG when pymalloc is
enabled. It's a detected error to define PYMALLOC_DEBUG when pymalloc
isn't enabled.
Two debugging entry points defined only under PYMALLOC_DEBUG:
+ _PyMalloc_DebugCheckAddress(const void *p) can be used (e.g., from gdb)
to sanity-check a memory block obtained from pymalloc. It sprays
info to stderr (see next) and dies via Py_FatalError if the block is
detectably damaged.
+ _PyMalloc_DebugDumpAddress(const void *p) can be used to spray info
about a debug memory block to stderr.
A tiny start at implementing "API family" checks isn't good for
anything yet.
_PyMalloc_DebugRealloc() has been optimized to do little when the new
size is <= old size. However, if the new size is larger, it really
can't call the underlying realloc() routine without either violating its
contract, or knowing something non-trivial about how the underlying
realloc() works. A memcpy is always done in this case.
This was a disaster for (and only) one of the std tests: test_bufio
creates single text file lines up to a million characters long. On
Windows, fileobject.c's get_line() uses the horridly funky
getline_via_fgets(), which keeps growing and growing a string object
hoping to find a newline. It grew the string object 1000 bytes each
time, so for a million-character string it took approximately forever
(I gave up after a few minutes).
So, also:
fileobject.c, getline_via_fgets(): When a single line is outrageously
long, grow the string object at a mildly exponential rate, instead of
just 1000 bytes at a time.
That's enough so that a debug-build test_bufio finishes in about 5 seconds
on my Win98SE box. I'm curious to try this on Win2K, because it has very
different memory behavior than Win9X, and test_bufio always took a factor
of 10 longer to complete on Win2K. It *could* be that the endless
reallocs were simply killing it on Win2K even in the release build.

In a PYMALLOC_DEBUG build obmalloc adds extra debugging info
to each allocated block. This was using 4 bytes for each such
piece of info regardless of platform. This didn't really matter
before (proof: no bug reports, and the debug-build obmalloc would
have assert-failed if it was ever asked for a chunk of memory
>= 2**32 bytes), since container indices were plain ints. But after
the Py_ssize_t changes, it's at least theoretically possible to
allocate a list or string whose guts exceed 2**32 bytes, and the
PYMALLOC_DEBUG routines would fail then (having only 4 bytes
to record the originally requested size).
Now we use sizeof(size_t) bytes for each of a PYMALLOC_DEBUG
build's extra debugging fields. This won't make any difference
on 32-bit boxes, but will add 16 bytes to each allocation in
a debug build on a 64-bit box.

Normalized a few cases of whitespace in function declarations.
Found them using::
find . -name '*.py' | while read i ; do grep 'def[^(]*( ' $i /dev/null ; done
find . -name '*.py' | while read i ; do grep ' ):' $i /dev/null ; done
(I was doing this all over my own code anyway, because I'd been using spaces in
all defs, so I thought I'd make a run on the Python code as well. If you need
to do such fixes in your own code, you can use xx-rename or parenregu.el within
emacs.)

SF patch 1501987: Remove randomness from test_exceptions,
from ?iga Seilnacht (sorry about the name, but Firefox
on my box can't display the first character of the name --
the SF "Unix name" is zseil).
This appears to cure the oddball intermittent leaks across
runs when running test_exceptions under -R. I'm not sure
why, but I'm too sleepy to care ;-)
The thrust of the SF patch was to remove randomness in the
pickle protocol used. I changed the patch to use
range(pickle.HIGHEST_PROTOCOL + 1), to try both pickle and
cPickle, and randomly mucked with other test lines to put
statements on their own lines.
Not a bugfix candidate (this is fiddling new-in-2.5 code).

[Bug #1497414] _self is a reserved word in the WATCOM 10.6 C compiler.
Fix by renaming the variable.
In a different module, Neal fixed it by renaming _self to self. There's

In a PYMALLOC_DEBUG build obmalloc adds extra debugging info
to each allocated block. This was using 4 bytes for each such
piece of info regardless of platform. This didn't really matter
before (proof: no bug reports, and the debug-build obmalloc would
have assert-failed if it was ever asked for a chunk of memory
>= 2**32 bytes), since container indices were plain ints. But after
the Py_ssize_t changes, it's at least theoretically possible to
allocate a list or string whose guts exceed 2**32 bytes, and the
PYMALLOC_DEBUG routines would fail then (having only 4 bytes
to record the originally requested size).
Now we use sizeof(size_t) bytes for each of a PYMALLOC_DEBUG
build's extra debugging fields. This won't make any difference
on 32-bit boxes, but will add 16 bytes to each allocation in
a debug build on a 64-bit box.

The first is causing many buildbots to fail test runs, and there
are multiple causes with seemingly no immediate prospects for
repairing them. See python-dev discussion.
Note that a branch can (and should) be created for resolving these

of runtest() and into some module-level helper functions.
This makes runtest() and the -R code easier to follow.
That in turn allowed seeing some opportunities for code
simplification, and made it obvious that reglog.txt
never got closed.

_PySys_Init(): It's rarely a good idea to size a buffer to the
exact maximum size someone guesses is needed. In this case, if
we're really worried about extreme integers, then "cp%d" can
actually need 14 bytes (2 for "cp" + 1 for \0 at the end +
11 for -(2**31-1)). So reserve 128 bytes instead -- nothing is
actually saved by making a stack-local buffer tiny.

SF patch 1501987: Remove randomness from test_exceptions,
from ?iga Seilnacht (sorry about the name, but Firefox
on my box can't display the first character of the name --
the SF "Unix name" is zseil).
This appears to cure the oddball intermittent leaks across
runs when running test_exceptions under -R. I'm not sure
why, but I'm too sleepy to care ;-)
The thrust of the SF patch was to remove randomness in the
pickle protocol used. I changed the patch to use
range(pickle.HIGHEST_PROTOCOL + 1), to try both pickle and
cPickle, and randomly mucked with other test lines to put
statements on their own lines.
Not a bugfix candidate (this is fiddling new-in-2.5 code).

The requested memory, filled with copies of PYMEM_CLEANBYTE.
|
Give Python a debug-mode pymalloc, much as sketched on Python-Dev.
When WITH_PYMALLOC is defined, define PYMALLOC_DEBUG to enable the debug
allocator. This can be done independent of build type (release or debug).
A debug build automatically defines PYMALLOC_DEBUG when pymalloc is
enabled. It's a detected error to define PYMALLOC_DEBUG when pymalloc
isn't enabled.
Two debugging entry points defined only under PYMALLOC_DEBUG:
+ _PyMalloc_DebugCheckAddress(const void *p) can be used (e.g., from gdb)
to sanity-check a memory block obtained from pymalloc. It sprays
info to stderr (see next) and dies via Py_FatalError if the block is
detectably damaged.
+ _PyMalloc_DebugDumpAddress(const void *p) can be used to spray info
about a debug memory block to stderr.
A tiny start at implementing "API family" checks isn't good for
anything yet.
_PyMalloc_DebugRealloc() has been optimized to do little when the new
size is <= old size. However, if the new size is larger, it really
can't call the underlying realloc() routine without either violating its
contract, or knowing something non-trivial about how the underlying
realloc() works. A memcpy is always done in this case.
This was a disaster for (and only) one of the std tests: test_bufio
creates single text file lines up to a million characters long. On
Windows, fileobject.c's get_line() uses the horridly funky
getline_via_fgets(), which keeps growing and growing a string object
hoping to find a newline. It grew the string object 1000 bytes each
time, so for a million-character string it took approximately forever
(I gave up after a few minutes).
So, also:
fileobject.c, getline_via_fgets(): When a single line is outrageously
long, grow the string object at a mildly exponential rate, instead of
just 1000 bytes at a time.
That's enough so that a debug-build test_bufio finishes in about 5 seconds
on my Win98SE box. I'm curious to try this on Win2K, because it has very
different memory behavior than Win9X, and test_bufio always took a factor
of 10 longer to complete on Win2K. It *could* be that the endless
reallocs were simply killing it on Win2K even in the release build.

In a PYMALLOC_DEBUG build obmalloc adds extra debugging info
to each allocated block. This was using 4 bytes for each such
piece of info regardless of platform. This didn't really matter
before (proof: no bug reports, and the debug-build obmalloc would
have assert-failed if it was ever asked for a chunk of memory
>= 2**32 bytes), since container indices were plain ints. But after
the Py_ssize_t changes, it's at least theoretically possible to
allocate a list or string whose guts exceed 2**32 bytes, and the
PYMALLOC_DEBUG routines would fail then (having only 4 bytes
to record the originally requested size).
Now we use sizeof(size_t) bytes for each of a PYMALLOC_DEBUG
build's extra debugging fields. This won't make any difference
on 32-bit boxes, but will add 16 bytes to each allocation in
a debug build on a 64-bit box.

The first is causing many buildbots to fail test runs, and there
are multiple causes with seemingly no immediate prospects for
repairing them. See python-dev discussion.
Note that a branch can (and should) be created for resolving these
problems, like
svn copy svn+ssh://svn.python.org/python/trunk -r46640 svn+ssh://svn.python.org/python/branches/NEW_BRANCH
followed by merging rev 46647 to the new branch.

_PySys_Init(): It's rarely a good idea to size a buffer to the
exact maximum size someone guesses is needed. In this case, if
we're really worried about extreme integers, then "cp%d" can
actually need 14 bytes (2 for "cp" + 1 for \0 at the end +
11 for -(2**31-1)). So reserve 128 bytes instead -- nothing is
actually saved by making a stack-local buffer tiny.

SF patch 1501987: Remove randomness from test_exceptions,
from ?iga Seilnacht (sorry about the name, but Firefox
on my box can't display the first character of the name --
the SF "Unix name" is zseil).
This appears to cure the oddball intermittent leaks across
runs when running test_exceptions under -R. I'm not sure
why, but I'm too sleepy to care ;-)
The thrust of the SF patch was to remove randomness in the
pickle protocol used. I changed the patch to use
range(pickle.HIGHEST_PROTOCOL + 1), to try both pickle and
cPickle, and randomly mucked with other test lines to put
statements on their own lines.
Not a bugfix candidate (this is fiddling new-in-2.5 code).

&p[2*S] is returned. Note that this is 8-byte aligned if pymalloc
|
Give Python a debug-mode pymalloc, much as sketched on Python-Dev.
When WITH_PYMALLOC is defined, define PYMALLOC_DEBUG to enable the debug
allocator. This can be done independent of build type (release or debug).
A debug build automatically defines PYMALLOC_DEBUG when pymalloc is
enabled. It's a detected error to define PYMALLOC_DEBUG when pymalloc
isn't enabled.
Two debugging entry points defined only under PYMALLOC_DEBUG:
+ _PyMalloc_DebugCheckAddress(const void *p) can be used (e.g., from gdb)
to sanity-check a memory block obtained from pymalloc. It sprays
info to stderr (see next) and dies via Py_FatalError if the block is
detectably damaged.
+ _PyMalloc_DebugDumpAddress(const void *p) can be used to spray info
about a debug memory block to stderr.
A tiny start at implementing "API family" checks isn't good for
anything yet.
_PyMalloc_DebugRealloc() has been optimized to do little when the new
size is <= old size. However, if the new size is larger, it really
can't call the underlying realloc() routine without either violating its
contract, or knowing something non-trivial about how the underlying
realloc() works. A memcpy is always done in this case.
This was a disaster for (and only) one of the std tests: test_bufio
creates single text file lines up to a million characters long. On
Windows, fileobject.c's get_line() uses the horridly funky
getline_via_fgets(), which keeps growing and growing a string object
hoping to find a newline. It grew the string object 1000 bytes each
time, so for a million-character string it took approximately forever
(I gave up after a few minutes).
So, also:
fileobject.c, getline_via_fgets(): When a single line is outrageously
long, grow the string object at a mildly exponential rate, instead of
just 1000 bytes at a time.
That's enough so that a debug-build test_bufio finishes in about 5 seconds
on my Win98SE box. I'm curious to try this on Win2K, because it has very
different memory behavior than Win9X, and test_bufio always took a factor
of 10 longer to complete on Win2K. It *could* be that the endless
reallocs were simply killing it on Win2K even in the release build.

[Bug #1497414] _self is a reserved word in the WATCOM 10.6 C compiler.
Fix by renaming the variable.
In a different module, Neal fixed it by renaming _self to self. There's

(I'm committing this on a Mac without Tk, but it's a simple search-and-replace.

In a PYMALLOC_DEBUG build obmalloc adds extra debugging info
to each allocated block. This was using 4 bytes for each such
piece of info regardless of platform. This didn't really matter
before (proof: no bug reports, and the debug-build obmalloc would
have assert-failed if it was ever asked for a chunk of memory
>= 2**32 bytes), since container indices were plain ints. But after
the Py_ssize_t changes, it's at least theoretically possible to
allocate a list or string whose guts exceed 2**32 bytes, and the
PYMALLOC_DEBUG routines would fail then (having only 4 bytes
to record the originally requested size).
Now we use sizeof(size_t) bytes for each of a PYMALLOC_DEBUG
build's extra debugging fields. This won't make any difference
on 32-bit boxes, but will add 16 bytes to each allocation in
a debug build on a 64-bit box.

SF patch 1501987: Remove randomness from test_exceptions,
from ?iga Seilnacht (sorry about the name, but Firefox
on my box can't display the first character of the name --
the SF "Unix name" is zseil).
This appears to cure the oddball intermittent leaks across
runs when running test_exceptions under -R. I'm not sure
why, but I'm too sleepy to care ;-)
The thrust of the SF patch was to remove randomness in the
pickle protocol used. I changed the patch to use
range(pickle.HIGHEST_PROTOCOL + 1), to try both pickle and
cPickle, and randomly mucked with other test lines to put
statements on their own lines.
Not a bugfix candidate (this is fiddling new-in-2.5 code).

[Bug #1497414] _self is a reserved word in the WATCOM 10.6 C compiler.
Fix by renaming the variable.
In a different module, Neal fixed it by renaming _self to self. There's

(I'm committing this on a Mac without Tk, but it's a simple search-and-replace.

In a PYMALLOC_DEBUG build obmalloc adds extra debugging info
to each allocated block. This was using 4 bytes for each such
piece of info regardless of platform. This didn't really matter
before (proof: no bug reports, and the debug-build obmalloc would
have assert-failed if it was ever asked for a chunk of memory
>= 2**32 bytes), since container indices were plain ints. But after
the Py_ssize_t changes, it's at least theoretically possible to
allocate a list or string whose guts exceed 2**32 bytes, and the
PYMALLOC_DEBUG routines would fail then (having only 4 bytes
to record the originally requested size).
Now we use sizeof(size_t) bytes for each of a PYMALLOC_DEBUG
build's extra debugging fields. This won't make any difference
on 32-bit boxes, but will add 16 bytes to each allocation in
a debug build on a 64-bit box.

The first is causing many buildbots to fail test runs, and there
are multiple causes with seemingly no immediate prospects for
repairing them. See python-dev discussion.
Note that a branch can (and should) be created for resolving these

_PySys_Init(): It's rarely a good idea to size a buffer to the
exact maximum size someone guesses is needed. In this case, if
we're really worried about extreme integers, then "cp%d" can
actually need 14 bytes (2 for "cp" + 1 for \0 at the end +
11 for -(2**31-1)). So reserve 128 bytes instead -- nothing is
actually saved by making a stack-local buffer tiny.

SF patch 1501987: Remove randomness from test_exceptions,
from ?iga Seilnacht (sorry about the name, but Firefox
on my box can't display the first character of the name --
the SF "Unix name" is zseil).
This appears to cure the oddball intermittent leaks across
runs when running test_exceptions under -R. I'm not sure
why, but I'm too sleepy to care ;-)
The thrust of the SF patch was to remove randomness in the
pickle protocol used. I changed the patch to use
range(pickle.HIGHEST_PROTOCOL + 1), to try both pickle and
cPickle, and randomly mucked with other test lines to put
statements on their own lines.
Not a bugfix candidate (this is fiddling new-in-2.5 code).

In a PYMALLOC_DEBUG build obmalloc adds extra debugging info
to each allocated block. This was using 4 bytes for each such
piece of info regardless of platform. This didn't really matter
before (proof: no bug reports, and the debug-build obmalloc would
have assert-failed if it was ever asked for a chunk of memory
>= 2**32 bytes), since container indices were plain ints. But after
the Py_ssize_t changes, it's at least theoretically possible to
allocate a list or string whose guts exceed 2**32 bytes, and the
PYMALLOC_DEBUG routines would fail then (having only 4 bytes
to record the originally requested size).
Now we use sizeof(size_t) bytes for each of a PYMALLOC_DEBUG
build's extra debugging fields. This won't make any difference
on 32-bit boxes, but will add 16 bytes to each allocation in
a debug build on a 64-bit box.

The first is causing many buildbots to fail test runs, and there
are multiple causes with seemingly no immediate prospects for
repairing them. See python-dev discussion.
Note that a branch can (and should) be created for resolving these
problems, like
svn copy svn+ssh://svn.python.org/python/trunk -r46640 svn+ssh://svn.python.org/python/branches/NEW_BRANCH
followed by merging rev 46647 to the new branch.

11 for -(2**31-1)). So reserve 128 bytes instead -- nothing is
actually saved by making a stack-local buffer tiny.

SF patch 1501987: Remove randomness from test_exceptions,
from ?iga Seilnacht (sorry about the name, but Firefox
on my box can't display the first character of the name --
the SF "Unix name" is zseil).
This appears to cure the oddball intermittent leaks across
runs when running test_exceptions under -R. I'm not sure
why, but I'm too sleepy to care ;-)
The thrust of the SF patch was to remove randomness in the
pickle protocol used. I changed the patch to use
range(pickle.HIGHEST_PROTOCOL + 1), to try both pickle and
cPickle, and randomly mucked with other test lines to put
statements on their own lines.
Not a bugfix candidate (this is fiddling new-in-2.5 code).

This is a big-endian size_t.
|
Give Python a debug-mode pymalloc, much as sketched on Python-Dev.
When WITH_PYMALLOC is defined, define PYMALLOC_DEBUG to enable the debug
allocator. This can be done independent of build type (release or debug).
A debug build automatically defines PYMALLOC_DEBUG when pymalloc is
enabled. It's a detected error to define PYMALLOC_DEBUG when pymalloc
isn't enabled.
Two debugging entry points defined only under PYMALLOC_DEBUG:
+ _PyMalloc_DebugCheckAddress(const void *p) can be used (e.g., from gdb)
to sanity-check a memory block obtained from pymalloc. It sprays
info to stderr (see next) and dies via Py_FatalError if the block is
detectably damaged.
+ _PyMalloc_DebugDumpAddress(const void *p) can be used to spray info
about a debug memory block to stderr.
A tiny start at implementing "API family" checks isn't good for
anything yet.
_PyMalloc_DebugRealloc() has been optimized to do little when the new
size is <= old size. However, if the new size is larger, it really
can't call the underlying realloc() routine without either violating its
contract, or knowing something non-trivial about how the underlying
realloc() works. A memcpy is always done in this case.
This was a disaster for (and only) one of the std tests: test_bufio
creates single text file lines up to a million characters long. On
Windows, fileobject.c's get_line() uses the horridly funky
getline_via_fgets(), which keeps growing and growing a string object
hoping to find a newline. It grew the string object 1000 bytes each
time, so for a million-character string it took approximately forever
(I gave up after a few minutes).
So, also:
fileobject.c, getline_via_fgets(): When a single line is outrageously
long, grow the string object at a mildly exponential rate, instead of
just 1000 bytes at a time.
That's enough so that a debug-build test_bufio finishes in about 5 seconds
on my Win98SE box. I'm curious to try this on Win2K, because it has very
different memory behavior than Win9X, and test_bufio always took a factor
of 10 longer to complete on Win2K. It *could* be that the endless
reallocs were simply killing it on Win2K even in the release build.

allocator. This can be done independent of build type (release or debug).
A debug build automatically defines PYMALLOC_DEBUG when pymalloc is
enabled. It's a detected error to define PYMALLOC_DEBUG when pymalloc
isn't enabled.
Two debugging entry points defined only under PYMALLOC_DEBUG:
+ _PyMalloc_DebugCheckAddress(const void *p) can be used (e.g., from gdb)
to sanity-check a memory block obtained from pymalloc. It sprays
info to stderr (see next) and dies via Py_FatalError if the block is
detectably damaged.
+ _PyMalloc_DebugDumpAddress(const void *p) can be used to spray info
about a debug memory block to stderr.
A tiny start at implementing "API family" checks isn't good for
anything yet.
_PyMalloc_DebugRealloc() has been optimized to do little when the new
size is <= old size. However, if the new size is larger, it really
can't call the underlying realloc() routine without either violating its
contract, or knowing something non-trivial about how the underlying
realloc() works. A memcpy is always done in this case.
This was a disaster for (and only) one of the std tests: test_bufio
creates single text file lines up to a million characters long. On
Windows, fileobject.c's get_line() uses the horridly funky
getline_via_fgets(), which keeps growing and growing a string object
hoping to find a newline. It grew the string object 1000 bytes each
time, so for a million-character string it took approximately forever
(I gave up after a few minutes).
So, also:
fileobject.c, getline_via_fgets(): When a single line is outrageously
long, grow the string object at a mildly exponential rate, instead of
just 1000 bytes at a time.
That's enough so that a debug-build test_bufio finishes in about 5 seconds
on my Win98SE box. I'm curious to try this on Win2K, because it has very
different memory behavior than Win9X, and test_bufio always took a factor
of 10 longer to complete on Win2K. It *could* be that the endless
reallocs were simply killing it on Win2K even in the release build.

Fix by renaming the variable.
In a different module, Neal fixed it by renaming _self to self. There's

(I'm committing this on a Mac without Tk, but it's a simple search-and-replace.

In a PYMALLOC_DEBUG build obmalloc adds extra debugging info
to each allocated block. This was using 4 bytes for each such
piece of info regardless of platform. This didn't really matter
before (proof: no bug reports, and the debug-build obmalloc would
have assert-failed if it was ever asked for a chunk of memory
>= 2**32 bytes), since container indices were plain ints. But after
the Py_ssize_t changes, it's at least theoretically possible to
allocate a list or string whose guts exceed 2**32 bytes, and the
PYMALLOC_DEBUG routines would fail then (having only 4 bytes
to record the originally requested size).
Now we use sizeof(size_t) bytes for each of a PYMALLOC_DEBUG
build's extra debugging fields. This won't make any difference
on 32-bit boxes, but will add 16 bytes to each allocation in
a debug build on a 64-bit box.

46647 Markup fix
The first is causing many buildbots to fail test runs, and there
are multiple causes with seemingly no immediate prospects for
repairing them. See python-dev discussion.
Note that a branch can (and should) be created for resolving these
problems, like
svn copy svn+ssh://svn.python.org/python/trunk -r46640 svn+ssh://svn.python.org/python/branches/NEW_BRANCH
followed by merging rev 46647 to the new branch.

"Flat is better than nested."
Move the long-winded, multiply-nested -R support out

This makes runtest() and the -R code easier to follow.
That in turn allowed seeing some opportunities for code
simplification, and made it obvious that reglog.txt

_PySys_Init(): It's rarely a good idea to size a buffer to the

we're really worried about extreme integers, then "cp%d" can
actually need 14 bytes (2 for "cp" + 1 for \0 at the end +
11 for -(2**31-1)). So reserve 128 bytes instead -- nothing is
actually saved by making a stack-local buffer tiny.

SF patch 1501987: Remove randomness from test_exceptions,
from ?iga Seilnacht (sorry about the name, but Firefox
on my box can't display the first character of the name --
the SF "Unix name" is zseil).
This appears to cure the oddball intermittent leaks across
runs when running test_exceptions under -R. I'm not sure
why, but I'm too sleepy to care ;-)
The thrust of the SF patch was to remove randomness in the
pickle protocol used. I changed the patch to use
range(pickle.HIGHEST_PROTOCOL + 1), to try both pickle and
cPickle, and randomly mucked with other test lines to put
statements on their own lines.
Not a bugfix candidate (this is fiddling new-in-2.5 code).

Give Python a debug-mode pymalloc, much as sketched on Python-Dev.
When WITH_PYMALLOC is defined, define PYMALLOC_DEBUG to enable the debug
allocator. This can be done independent of build type (release or debug).
A debug build automatically defines PYMALLOC_DEBUG when pymalloc is
enabled. It's a detected error to define PYMALLOC_DEBUG when pymalloc
isn't enabled.
Two debugging entry points defined only under PYMALLOC_DEBUG:
+ _PyMalloc_DebugCheckAddress(const void *p) can be used (e.g., from gdb)
to sanity-check a memory block obtained from pymalloc. It sprays
info to stderr (see next) and dies via Py_FatalError if the block is
detectably damaged.
+ _PyMalloc_DebugDumpAddress(const void *p) can be used to spray info
about a debug memory block to stderr.
A tiny start at implementing "API family" checks isn't good for
anything yet.
_PyMalloc_DebugRealloc() has been optimized to do little when the new
size is <= old size. However, if the new size is larger, it really
can't call the underlying realloc() routine without either violating its
contract, or knowing something non-trivial about how the underlying
realloc() works. A memcpy is always done in this case.
This was a disaster for (and only) one of the std tests: test_bufio
creates single text file lines up to a million characters long. On
Windows, fileobject.c's get_line() uses the horridly funky
getline_via_fgets(), which keeps growing and growing a string object
hoping to find a newline. It grew the string object 1000 bytes each
time, so for a million-character string it took approximately forever
(I gave up after a few minutes).
So, also:
fileobject.c, getline_via_fgets(): When a single line is outrageously
long, grow the string object at a mildly exponential rate, instead of
just 1000 bytes at a time.
That's enough so that a debug-build test_bufio finishes in about 5 seconds
on my Win98SE box. I'm curious to try this on Win2K, because it has very
different memory behavior than Win9X, and test_bufio always took a factor
of 10 longer to complete on Win2K. It *could* be that the endless
reallocs were simply killing it on Win2K even in the release build.

Give Python a debug-mode pymalloc, much as sketched on Python-Dev.
When WITH_PYMALLOC is defined, define PYMALLOC_DEBUG to enable the debug
allocator. This can be done independent of build type (release or debug).
A debug build automatically defines PYMALLOC_DEBUG when pymalloc is
enabled. It's a detected error to define PYMALLOC_DEBUG when pymalloc
isn't enabled.
Two debugging entry points defined only under PYMALLOC_DEBUG:
+ _PyMalloc_DebugCheckAddress(const void *p) can be used (e.g., from gdb)
to sanity-check a memory block obtained from pymalloc. It sprays
info to stderr (see next) and dies via Py_FatalError if the block is

Give Python a debug-mode pymalloc, much as sketched on Python-Dev.
When WITH_PYMALLOC is defined, define PYMALLOC_DEBUG to enable the debug
allocator. This can be done independent of build type (release or debug).
A debug build automatically defines PYMALLOC_DEBUG when pymalloc is
enabled. It's a detected error to define PYMALLOC_DEBUG when pymalloc
isn't enabled.
Two debugging entry points defined only under PYMALLOC_DEBUG:
+ _PyMalloc_DebugCheckAddress(const void *p) can be used (e.g., from gdb)
to sanity-check a memory block obtained from pymalloc. It sprays
info to stderr (see next) and dies via Py_FatalError if the block is
detectably damaged.
+ _PyMalloc_DebugDumpAddress(const void *p) can be used to spray info
about a debug memory block to stderr.
A tiny start at implementing "API family" checks isn't good for
anything yet.
_PyMalloc_DebugRealloc() has been optimized to do little when the new
size is <= old size. However, if the new size is larger, it really
can't call the underlying realloc() routine without either violating its
contract, or knowing something non-trivial about how the underlying
realloc() works. A memcpy is always done in this case.
This was a disaster for (and only) one of the std tests: test_bufio
creates single text file lines up to a million characters long. On
Windows, fileobject.c's get_line() uses the horridly funky
getline_via_fgets(), which keeps growing and growing a string object
hoping to find a newline. It grew the string object 1000 bytes each
time, so for a million-character string it took approximately forever
(I gave up after a few minutes).
So, also:
fileobject.c, getline_via_fgets(): When a single line is outrageously
long, grow the string object at a mildly exponential rate, instead of
just 1000 bytes at a time.
That's enough so that a debug-build test_bufio finishes in about 5 seconds
on my Win98SE box. I'm curious to try this on Win2K, because it has very
different memory behavior than Win9X, and test_bufio always took a factor
of 10 longer to complete on Win2K. It *could* be that the endless
reallocs were simply killing it on Win2K even in the release build.

_PyMem_DebugCheckAddress(const char *func, char api, const void *p)
|
Give Python a debug-mode pymalloc, much as sketched on Python-Dev.
When WITH_PYMALLOC is defined, define PYMALLOC_DEBUG to enable the debug
allocator. This can be done independent of build type (release or debug).
A debug build automatically defines PYMALLOC_DEBUG when pymalloc is
enabled. It's a detected error to define PYMALLOC_DEBUG when pymalloc
isn't enabled.
Two debugging entry points defined only under PYMALLOC_DEBUG:
+ _PyMalloc_DebugCheckAddress(const void *p) can be used (e.g., from gdb)
to sanity-check a memory block obtained from pymalloc. It sprays
info to stderr (see next) and dies via Py_FatalError if the block is
detectably damaged.
+ _PyMalloc_DebugDumpAddress(const void *p) can be used to spray info
about a debug memory block to stderr.
A tiny start at implementing "API family" checks isn't good for
anything yet.
_PyMalloc_DebugRealloc() has been optimized to do little when the new
size is <= old size. However, if the new size is larger, it really
can't call the underlying realloc() routine without either violating its
contract, or knowing something non-trivial about how the underlying
realloc() works. A memcpy is always done in this case.
This was a disaster for (and only) one of the std tests: test_bufio
creates single text file lines up to a million characters long. On
Windows, fileobject.c's get_line() uses the horridly funky
getline_via_fgets(), which keeps growing and growing a string object
hoping to find a newline. It grew the string object 1000 bytes each
time, so for a million-character string it took approximately forever
(I gave up after a few minutes).
So, also:
fileobject.c, getline_via_fgets(): When a single line is outrageously
long, grow the string object at a mildly exponential rate, instead of
just 1000 bytes at a time.
That's enough so that a debug-build test_bufio finishes in about 5 seconds
on my Win98SE box. I'm curious to try this on Win2K, because it has very
different memory behavior than Win9X, and test_bufio always took a factor
of 10 longer to complete on Win2K. It *could* be that the endless
reallocs were simply killing it on Win2K even in the release build.

Fix by renaming the variable.
In a different module, Neal fixed it by renaming _self to self. There's
already a variable named 'self' here, so I used selfptr.
(I'm committing this on a Mac without Tk, but it's a simple search-and-replace.
<crosses fingers>, so I'll watch the buildbots and see what happens.)

In a PYMALLOC_DEBUG build obmalloc adds extra debugging info
to each allocated block. This was using 4 bytes for each such
piece of info regardless of platform. This didn't really matter
before (proof: no bug reports, and the debug-build obmalloc would
have assert-failed if it was ever asked for a chunk of memory
>= 2**32 bytes), since container indices were plain ints. But after
the Py_ssize_t changes, it's at least theoretically possible to
allocate a list or string whose guts exceed 2**32 bytes, and the
PYMALLOC_DEBUG routines would fail then (having only 4 bytes
to record the originally requested size).
Now we use sizeof(size_t) bytes for each of a PYMALLOC_DEBUG
build's extra debugging fields. This won't make any difference
on 32-bit boxes, but will add 16 bytes to each allocation in
a debug build on a 64-bit box.

The first is causing many buildbots to fail test runs, and there
are multiple causes with seemingly no immediate prospects for
repairing them. See python-dev discussion.
Note that a branch can (and should) be created for resolving these
problems, like
svn copy svn+ssh://svn.python.org/python/trunk -r46640 svn+ssh://svn.python.org/python/branches/NEW_BRANCH
followed by merging rev 46647 to the new branch.

_PySys_Init(): It's rarely a good idea to size a buffer to the
exact maximum size someone guesses is needed. In this case, if
we're really worried about extreme integers, then "cp%d" can
actually need 14 bytes (2 for "cp" + 1 for \0 at the end +
11 for -(2**31-1)). So reserve 128 bytes instead -- nothing is
actually saved by making a stack-local buffer tiny.

SF patch 1501987: Remove randomness from test_exceptions,
from ?iga Seilnacht (sorry about the name, but Firefox
on my box can't display the first character of the name --
the SF "Unix name" is zseil).
This appears to cure the oddball intermittent leaks across
runs when running test_exceptions under -R. I'm not sure
why, but I'm too sleepy to care ;-)
The thrust of the SF patch was to remove randomness in the
pickle protocol used. I changed the patch to use
range(pickle.HIGHEST_PROTOCOL + 1), to try both pickle and
cPickle, and randomly mucked with other test lines to put
statements on their own lines.
Not a bugfix candidate (this is fiddling new-in-2.5 code).

Fixes SF python patch/bug #1408584.
Also cleans up the bsddb.dbtables docstrings since thats the only
documentation that exists for that unadvertised module. (people
really should really just use sqlite3)

(arre, arigo) SF bug #1350060
Give a consistent behavior for comparison and hashing of method objects
(both user- and built-in methods). Now compares the 'self' recursively.
The hash was already asking for the hash of 'self'.

Argh. "integer" is a very confusing word ;)
Actually, checking for INT_MAX and INT_MIN is correct since
the format code explicitly handles a C "int".
