This moves repetitive logic accessing data edges into its own header, and more strongly defines the notion of what a data edge is, enforcing the internal invariants. This will also be incorporated in optimized Cord iteration logic once CordRepConcat is totally removed from the Cord code. PiperOrigin-RevId: 429307248 -- 6a0903962155988085bf8656743fda9c4cdcba6c by Abseil Team <absl-team@google.com>: Make it clear that the probability function given for the zipf distribution is unnormalized, i.e., sum(p(x) for x = 0..k) != 100%. Quoting Section 7 of the paper cited in the comments, where this formula comes from (emphasis mine): "We will consider the two parameter generalization as defined in Dagpunar [1988] with the unnormalized probability function ..."

Abseil Team	1ae9b71c47	Export of internal Abseil changes -- ac1df60490c9583e475e22de7adfc40023196fbf by Martijn Vels <mvels@google.com>: Change Cord constructor(string_view) to explicit make_tree and Cordz tracking This CL changes the ctor to use an easier to maintain model where Cord code explicitly invokes Cordz update or new / tree logic, which avoids the ambiguity of the 'branched' InlineRep::set_tree code. This removes the need to equip InlineRep with 'MethodIdentifier' or other necessary call info, and also is a cleaner model: InlineRep is carrying too much code now that should plainly sit in Cord, especially with all internal abstractions having moved to InlineData. See child CL(s) for desired state PiperOrigin-RevId: 369433619 -- b665af7f586e6c679a8b27d4f78d5a1d2b596058 by Abseil Team <absl-team@google.com>: Rename the 'Compare' template type to 'LessThan', as the passed-in function is expected to act like operator<. It is worth avoiding confusion with std::compare, which returns an int (-1/0/1), as due to implicit casting this can lead to hard-to-spot bugs. PiperOrigin-RevId: 369391118 -- c3c775269cad0f4982ec63f3616dd78bb9e52dca by Martijn Vels <mvels@google.com>: Integrate CordzUpdateTracker into CordzInfo PiperOrigin-RevId: 369348824 -- 771d81ed357496c117179e1daec76eba5155932d by Martijn Vels <mvels@google.com>: Replace mutex() with Lock() / Unlock() function Mini design future tracking of CordzInfo sampled cords: CordzInfo holds a CordRep* reference without a reference count. Cord is responsible for synchronizing updates for sampled cords such that the CordRep* contained in CordzInfo is at all times valid. This is done by scoping Lock() and Unlock() calls around the code modifying the code of a sampled cord. For example (using the future CL CordzUpdateScope()): CordzInfo* cordz_info = get_cordz_info(); CordzUpdateScope scope(cordz_info, CordzUpdateTracker::kRemovePrefix); CordRep* rep = RemovePrefixImpl(root); set_tree(rep); if (cordz_info) { cordz_info->SetCordRep(rep); } On CordzInfo::Unlock(), if the internal rep is null, the cord is no longer sampled, and CordzInfo will be deleted. Thus any update resulting in the Cord being inlined will automatically no longer be sampled.

That bit is still present in instructions and ELF symbol tables, though; it’s repurposed to indicate whether the function contains ARM or Thumb code. If the symbolizer doesn’t ignore that bit, it will believe Thumb functions have boundaries that are off by one byte, so instruct the symbolizer to null out the lowest-order bit after retrieving it from the symbol table.

This is a change based on an observation in RPC benchmarks that shows significant cycles being spent in waking up a thread, 99.8% of which was on cache misses. Investigating this a bit more, it turns out to be due to sharing the cache line with the waiter state. To fix this issue, the following changes are introduced: - Reorder fields in PerThreadSync so that it fits in a single cache line The size of this structure was 80 bytes before this change. Note: Manually inspected all booleans to make sure they are not modified by multiple threads concurrently.

PiperOrigin-RevId: 311844448 -- bdbe6b5b29791dbc3816ada1828458b3010ff1e9 by Laramie Leavitt <lar@google.com>: Change many distribution tests to use pcg_engine as a deterministic source of entropy. It's reasonable to test that the BitGen itself has good entropy, however when testing the cross product of all random distributions x all the architecture variations x all submitted changes results in a large number of tests. In order to account for these failures while still using good entropy requires that our allowed sigma need to account for all of these independent tests. Our current sigma values are too restrictive, and we see a lot of failures, so we have to either relax the sigma values or convert some of the statistical tests to use deterministic values. This changelist does the latter. PiperOrigin-RevId: 311840096 GitOrigin-RevId: f012012ef78234a6a4585321b67d7b7c92ebc266 Change-Id: Ic84886f38ff30d7d72c126e9b63c9a61eb729a1a	5 years ago
