/*
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.

/* Let S = sizeof(size_t). The debug malloc asks for 4*S extra bytes and
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 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.

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).

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.

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.

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.
