/* 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
* ----------------------------------------------------------------
* 1-8 8 0
* 9-16 16 1
* 17-24 24 2

/*
* 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.
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.

/*
address_in_range(P, POOL)
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
variable and pass the latter to the macro; because address_in_range is
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
B <= P < B + ARENA_SIZE
Subtracting B throughout, this is true iff
0 <= P-B < ARENA_SIZE
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
(NULL)). Therefore address_in_range correctly reports that obmalloc
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:
P < ARENA_SIZE
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>.

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.

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. ........ r46638 | tim.peters | 2006-06-04 05:38:04 +0200 (Sun, 04 Jun 2006) | 4 lines _PyObject_DebugMalloc(): The return value should add 2*sizeof(size_t) now, not 8.

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. ........ r46638 | tim.peters | 2006-06-04 05:38:04 +0200 (Sun, 04 Jun 2006) | 4 lines _PyObject_DebugMalloc(): The return value should add 2*sizeof(size_t) now, not 8.

/* Read sizeof(size_t) bytes at p as a big-endian size_t. */
static size_t
read_size_t(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.

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.

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.

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. ........ r46638 | tim.peters | 2006-06-04 05:38:04 +0200 (Sun, 04 Jun 2006) | 4 lines _PyObject_DebugMalloc(): The return value should add 2*sizeof(size_t) now, not 8.

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.

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. ........ r46638 | tim.peters | 2006-06-04 05:38:04 +0200 (Sun, 04 Jun 2006) | 4 lines _PyObject_DebugMalloc(): The return value should add 2*sizeof(size_t) now, not 8.

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.

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. ........ r46638 | tim.peters | 2006-06-04 05:38:04 +0200 (Sun, 04 Jun 2006) | 4 lines _PyObject_DebugMalloc(): The return value should add 2*sizeof(size_t) now, not 8.

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.

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.

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.

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. ........ r46638 | tim.peters | 2006-06-04 05:38:04 +0200 (Sun, 04 Jun 2006) | 4 lines _PyObject_DebugMalloc(): The return value should add 2*sizeof(size_t) now, not 8.

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. ........ r46638 | tim.peters | 2006-06-04 05:38:04 +0200 (Sun, 04 Jun 2006) | 4 lines _PyObject_DebugMalloc(): The return value should add 2*sizeof(size_t) now, not 8.

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.

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. ........ r46638 | tim.peters | 2006-06-04 05:38:04 +0200 (Sun, 04 Jun 2006) | 4 lines _PyObject_DebugMalloc(): The return value should add 2*sizeof(size_t) now, not 8.

&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.

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 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. ........ r46638 | tim.peters | 2006-06-04 05:38:04 +0200 (Sun, 04 Jun 2006) | 4 lines _PyObject_DebugMalloc(): The return value should add 2*sizeof(size_t) now, not 8.

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.

If "bad memory" is detected later, the serial number gives an
excellent way to set a breakpoint on the next run, to capture the
instant at which this block was passed out.
If PYMEM_DEBUG_SERIALNO is not defined (default), the debug malloc only asks
for 3 * S extra bytes, and omits the last serialno field.

This was using 4 bytes for each such piece of info regardless of platform.

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.

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.

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.

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. ........ r46638 | tim.peters | 2006-06-04 05:38:04 +0200 (Sun, 04 Jun 2006) | 4 lines _PyObject_DebugMalloc(): The return value should add 2*sizeof(size_t) now, not 8.
