* New PYMALLOC_DEBUG function void _PyMalloc_DebugDumpStats(void).Tim Peters2002-04-012-1/+98
| | | | | | | | | | | | | This displays stats about the # of arenas, pools, blocks and bytes, to stderr, both used and reserved but unused. CAUTION: Because PYMALLOC_DEBUG is on, the debug malloc routine adds 16 bytes to each request. This makes each block appear two size classes higher than it would be if PYMALLOC_DEBUG weren't on. So far, playing with this confirms the obvious: there's a lot of activity in the "small dict" size class, but nothing in the core makes any use of the 8-byte or 16-byte classes.

| | | | | | | I really can't test this, but from reading the discussion in that bug report, it's likely that this works. It may also close a whole bunch of other bug reports related to urllib and proxies on Windows, but who knows.

Found a hidden assumption that a pool contains room for at least two blocks, and added an assert to catch a violation if it ever happens in a place where that matters. Gave the normal "I allocated this block" case a longer basic block to work with before it has to do its first branch (via breaking apart an embedded assignment in an "if", and hoisting common code out of both branches).

| | | | | | | | | | | | | | | | | | | address obtained from system malloc/realloc without holding the GIL. When the vector of arena base addresses has to grow, the old vector is deliberately leaked. This makes "stale" x-thread references safe. arenas and narenas are also declared volatile, and changed in an order that prevents a thread from picking up a value of narenas too large for the value of arenas it sees. Added more asserts. Fixed an old inaccurate comment. Added a comment explaining why it's safe to call pymalloc free/realloc with an address obtained from system malloc/realloc even when arenas is still NULL (this is obscure, since the ADDRESS_IN_RANGE macro appears <wink> to index into arenas).

| | | | | | | | | | | | | | | | | | | | | | waste the first pool if malloc happens to return a pool-aligned address. This means the number of pools per arena can now vary by 1. Unfortunately, the code counted up from 0 to a presumed constant number of pools. So changed the increasing "watermark" counter to a decreasing "nfreepools" counter instead, and fiddled various stuff accordingly. This also allowed getting rid of two more macros. Also changed the code to align the first address to a pool boundary instead of a page boundary. These are two parallel sets of macro #defines that happen to be identical now, but the page macros are in theory more restrictive (bigger), and there's simply no reason I can see that it wasn't aligning to the less restrictive pool size all along (the code only relies on pool alignment). Hmm. The "page size" macros aren't used for anything *except* defining the pool size macros, and the comments claim the latter isn't necessary. So this has the feel of a layer of indirection that doesn't serve a purpose; should probably get rid of the page macros now.
* Retract the claim that this is always safe if PyMem_{Del, DEL, Free, FREE}Tim Peters2002-03-301-0/+4
| | | | | | | are called without the GIL. It's incredibly unlikely to fail, but I can't make this bulletproof without either adding a lock for exclusion, or giving up on growing the arena base-address vector (it would be safe if this were a static array).
* Lots of changes:Tim Peters2002-03-301-127/+225
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | + 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>.
