* absl: fix Mutex writer starvation related to uninit priorityGravatar Abseil Team2023-06-16
| | | | | | | | | | | | | | | | | | Currently when we queue the first thread, we don't init its priority. Subsequent queued threads init priority, but they compare it against the first thread priority, which is uninit. Thus the order can be wrong. It can lead to complete false starvation in some corner cases. On Linux the default priority is 0, which matches the uninit value, thus the problem is harder to spot on Linux (only possible if explicit thread priorities are used). But on Darwin the default priority is 31, thus the first thread falsely looks like lower priority than subsequently queued threads. The added test exposes the problem on Darwin. Always initialize the priority before queuing threads. PiperOrigin-RevId: 540814133 Change-Id: I513ce1493a67afe77d3e92fb49000b046b42a9f2

* | Fix behaviors of StrCat() and StrFormat() regarding char types and enum types.Gravatar Greg Falcon2023-06-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a conservative change, in that it only contains bugfixes and allows new patterns that used to be compile errors. There are other changes we would like to make (as reflected in the comments in char_formatting_test.cc), but we are being careful about the implications of such behavior changes. The two implementation changes are: * Apply integral promotions to enums before printing them, so they are always treated as integers (and not chars) by StrCat and StrFormat. * Classify `unsigned char` and `signed char` as integer-like rather than char-like, so that `StrFormat("%v", v)` accepts those types as integers (consistent with `StrCat()`.) The behavior changes are: * StrCat() now accepts char-backed enums (rather than failing to compile). * StrFormat("%v") now accepts `signed char` and `unsigned char` as integral (rather than failing to compile). * StrFormat("%v") now correctly formats 8-bit enums as integers (rather than failing internally and emitting nothing). Tested: Modified the char_formatting_test.cc case to reflect changes. Re-ran all other tests. PiperOrigin-RevId: 539659674 Change-Id: Ief56335f5a57e4582af396d00eaa9e7b6be4ddc6
* | DirectMmap: Use off_t instead of off64_t for the offset parameterGravatar Derek Mauro2023-06-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | off_t is best for portability. Its size varies with the platform. off64_t is non-standard, but is present in glibc and some BSDs. It also matches the signature specified in the manual. https://man7.org/linux/man-pages/man2/mmap.2.html This is a re-spin of #1349, but correctly casts the type to the type expected by the kernel for mmap2. https://man7.org/linux/man-pages/man2/mmap2.2.html Fixes #1473 PiperOrigin-RevId: 539656313 Change-Id: I7a30dd9d3eb6af03a99da0d93d721a86f6521b25
| * Fix buffer overflow in a placement `new[]` storage test.Gravatar Andrei Polushin2023-06-12

* Optimize Cord Refcount decrement.Gravatar Connal de Souza2023-06-09
| | | | | | | Introduce kHighRefcountMask which masks off flags and the LSb of the refcount value. In the cases where this mask is used, we don't need to check the LSb because we can assume the refcount is 1 when the rest of the masked RefcountAndFlags is empty, and the LSb doesn't matter if the masked value is not empty (either it's immortal or refcount > 1). This saves an instruction and a cycle (and + cmp -> tst) https://godbolt.org/z/Kz69eqfhq PiperOrigin-RevId: 539151659 Change-Id: I2ec7d72918f052c4b0938edd746af9d5b3052c7e

* | Fix unwinding through nested signal frames on aarch64.Gravatar Abseil Team2023-06-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes an endless loop in the absl Arm stack unwinder where encountering a second signal return trampoline (as one has in nested signal frames), would restart unwinding at the outermost signal, resulting in an endless loop. This does not change any behavior in the non-nested signal case, so I believe it is safe for any stack that hasn't encountered this bug already. I would love to test this beyond the absl unwinding test cases and the fingerprint_test included here, but I'm at a loss for other test cases.
