Before you use this module, please give the -// name of your internal namespace for this module. Or, if you want -// to expose it, you'll want to move it to the Google namespace. We -// cannot put this class in global namespace because there can be some -// problems when we have multiple versions of Mutex in each shared object. -// -// NOTE: TryLock() is broken for NO_THREADS mode, at least in NDEBUG -// mode. -// -// CYGWIN NOTE: Cygwin support for rwlock seems to be buggy: -// http://www.cygwin.com/ml/cygwin/2008-12/msg00017.html -// Because of that, we might as well use windows locks for -// cygwin. They seem to be more reliable than the cygwin pthreads layer. -// -// TRICKY IMPLEMENTATION NOTE: -// This class is designed to be safe to use during -// dynamic-initialization -- that is, by global constructors that are -// run before main() starts. The issue in this case is that -// dynamic-initialization happens in an unpredictable order, and it -// could be that someone else's dynamic initializer could call a -// function that tries to acquire this mutex -- but that all happens -// before this mutex's constructor has run. (This can happen even if -// the mutex and the function that uses the mutex are in the same .cc -// file.) Basically, because Mutex does non-trivial work in its -// constructor, it's not, in the naive implementation, safe to use -// before dynamic initialization has run on it. -// -// The solution used here is to pair the actual mutex primitive with a -// bool that is set to true when the mutex is dynamically initialized. -// (Before that it's false.) Then we modify all mutex routines to -// look at the bool, and not try to lock/unlock until the bool makes -// it to true (which happens after the Mutex constructor has run.) -// -// This works because before main() starts -- particularly, during -// dynamic initialization -- there are no threads, so a) it's ok that -// the mutex operations are a no-op, since we don't need locking then -// anyway; and b) we can be quite confident our bool won't change -// state between a call to Lock() and a call to Unlock() (that would -// require a global constructor in one translation unit to call Lock() -// and another global constructor in another translation unit to call -// Unlock() later, which is pretty perverse). -// -// That said, it's tricky, and can conceivably fail; it's safest to -// avoid trying to acquire a mutex in a global constructor, if you -// can. One way it can fail is that a really smart compiler might -// initialize the bool to true at static-initialization time (too -// early) rather than at dynamic-initialization time. To discourage -// that, we set is_safe_ to true in code (not the constructor -// colon-initializer) and set it to true via a function that always -// evaluates to true, but that the compiler can't know always -// evaluates to true. This should be good enough. -// -// A related issue is code that could try to access the mutex -// after it's been destroyed in the global destructors (because -// the Mutex global destructor runs before some other global -// destructor, that tries to acquire the mutex). The way we -// deal with this is by taking a constructor arg that global -// mutexes should pass in, that causes the destructor to do no -// work.

We use the -// malloc-zone functionality built into OS X to register our malloc -// routine. -// -// 1) We used to use the normal 'override weak libc malloc/etc' -// technique for OS X. This is not optimal because mach does not -// support the 'alias' attribute, so we had to have forwarding -// functions. It also does not work very well with OS X shared -// libraries (dylibs) -- in general, the shared libs don't use -// tcmalloc unless run with the DYLD_FORCE_FLAT_NAMESPACE envvar. -// -// 2) Another approach would be to use an interposition array: -// static const interpose_t interposers[] __attribute__((section("__DATA, __interpose"))) = { -// { (void *)tc_malloc, (void *)malloc }, -// { (void *)tc_free, (void *)free }, -// }; -// This requires the user to set the DYLD_INSERT_LIBRARIES envvar, so -// is not much better. -// -// 3) Registering a new malloc zone avoids all these issues: -// http://www.opensource.apple.com/source/Libc/Libc-583/include/malloc/malloc.h -// http://www.opensource.apple.com/source/Libc/Libc-583/gen/malloc.c -// If we make tcmalloc the default malloc zone (undocumented but -// possible) then all new allocs use it, even those in shared -// libraries. Allocs done before tcmalloc was installed, or in libs -// that aren't using tcmalloc for some reason, will correctly go -// through the malloc-zone interface when free-ing, and will pick up -// the libc free rather than tcmalloc free. So it should "never" -// cause a crash (famous last words). -// -// 4) The routines one must define for one's own malloc have changed -// between OS X versions. This requires some hoops on our part, but -// is only really annoying when it comes to posix_memalign. The right -// behavior there depends on what OS version tcmalloc was compiled on, -// but also what OS version the program is running on. For now, we -// punt and don't implement our own posix_memalign.

The types of the key and value -// must be unsigned integral types or at least have unsigned semantics -// for >>, casting, and similar operations. -// -// Synchronization is not provided. However, the cache is implemented -// as an array of cache entries whose type is chosen at compile time. -// If a[i] is atomic on your hardware for the chosen array type then -// raciness will not necessarily lead to bugginess. The cache entries -// must be large enough to hold a partial key and a value packed -// together. The partial keys are bit strings of length -// kKeybits - kHashbits, and the values are bit strings of length kValuebits. -// -// In an effort to use minimal space, every cache entry represents -// some pair; the class provides no way to mark a cache -// entry as empty or uninitialized. In practice, you may want to have -// reserved keys or values to get around this limitation. For example, in -// tcmalloc's PageID-to-sizeclass cache, a value of 0 is used as -// "unknown sizeclass." -// -// Usage Considerations -// -------------------- -// -// kHashbits controls the size of the cache. The best value for -// kHashbits will of course depend on the application. Perhaps try -// tuning the value of kHashbits by measuring different values on your -// favorite benchmark. Also remember not to be a pig; other -// programs that need resources may suffer if you are. -// -// The main uses for this class will be when performance is -// critical and there's a convenient type to hold the cache's -// entries. As described above, the number of bits required -// for a cache entry is (kKeybits - kHashbits) + kValuebits. Suppose -// kKeybits + kValuebits is 43. Then it probably makes sense to -// chose kHashbits >= 11 so that cache entries fit in a uint32. -// -// On the other hand, suppose kKeybits = kValuebits = 64. Then -// using this class may be less worthwhile. You'll probably -// be using 128 bits for each entry anyway, so maybe just pick -// a hash function, H, and use an array indexed by H(key): -// void Put(K key, V value) { a_[H(key)] = pair(key, value); } -// V GetOrDefault(K key, V default) { const pair &p = a_[H(key)]; ... } -// etc. -// -// Further Details -// --------------- -// -// For caches used only by one thread, the following is true: -// 1. For a cache c, -// (c.Put(key, value), c.GetOrDefault(key, 0)) == value -// and -// (c.Put(key, value), <...>, c.GetOrDefault(key, 0)) == value -// if the elided code contains no c.Put calls. -// -// 2. Has(key) will return false if no pair with that key -// has ever been Put. However, a newly initialized cache will have -// some pairs already present. When you create a new -// cache, you must specify an "initial value." The initialization -// procedure is equivalent to Clear(initial_value), which is -// equivalent to Put(k, initial_value) for all keys k from 0 to -// 2^kHashbits - 1. -// -// 3. If key and key' differ then the only way Put(key, value) may -// cause Has(key') to change is that Has(key') may change from true to -// false. Furthermore, a Put() call that doesn't change Has(key') -// doesn't change GetOrDefault(key', ...) either. -// -// Implementation details: -// -// This is a direct-mapped cache with 2^kHashbits entries; the hash -// function simply takes the low bits of the key. We store whole keys -// if a whole key plus a whole value fits in an entry. Otherwise, an -// entry is the high bits of a key and a value, packed together. -// E.g., a 20 bit key and a 7 bit value only require a uint16 for each -// entry if kHashbits >= 11. -// -// Alternatives to this scheme will be added as needed. - -#ifndef TCMALLOC_PACKED_CACHE_INL_H_ -#define TCMALLOC_PACKED_CACHE_INL_H_ - -#include "config.h" -#include // for size_t -#ifdef HAVE_STDINT_H -#include // for uintptr_t -#endif -#include "base/basictypes.h" -#include "internal_logging.h" - -// A safe way of doing "(1 << n) - 1" -- without worrying about overflow -// Note this will all be resolved to a constant expression at compile-time -#define N_ONES_(IntType, N) \ - ( (N) == 0 ? 0 : ((static_cast(1) << ((N)-1))-1 + \ - (static_cast(1) << ((N)-1))) ) - -// The types K and V provide upper bounds on the number of valid keys -// and values, but we explicitly require the keys to be less than -// 2^kKeybits and the values to be less than 2^kValuebits.

Sigh. - - Why is this important? Imagine that a wrapper has a stack - allocated local, and passes to the hidden call, a pointer to it. - Because gcc does not know about the hidden call, it may allocate - that local in the redzone. Unfortunately the hidden call may then - trash it before it comes to use it. So we must step clear of the - redzone, for the duration of the hidden call, to make it safe. - - Probably the same problem afflicts the other redzone-style ABIs too - (ppc64-linux, ppc32-aix5, ppc64-aix5);
