* bpo-34602: Avoid failures setting macOS stack resource limit (GH-14546) ↵Miss Islington (bot)2019-07-021-0/+6
| | | | | | | | | | | | | | | | | | | | | | (GH-14549) Under some conditions the earlier fix for bpo-18075, "Infinite recursion tests triggering a segfault on Mac OS X", now causes failures on macOS when attempting to change stack limit with resource.setrlimit resource.RLIMIT_STACK, like regrtest does when running the test suite. The reverted change had specified a non-default stack size when linking the python executable on macOS. As of macOS 10.14.4, the previous code causes a hard failure when running tests, although similar failures had been seen under some conditions under some earlier systems. Reverting the change to the interpreter stack size at link time helped for release builds but caused some tests to fail when built --with-pydebug. Try the opposite approach: continue to build the interpreter with an increased stack size on macOS and remove the failing setrlimit call in regrtest initialization. This will definitely avoid the resource.RLIMIT_STACK error and should have no, or fewer, side effects.

* [3.6] bpo-35257: Avoid leaking LTO linker flags into distutils (GH-10900) ↵Victor Stinner2018-12-201-1/+3
| | | | | | | | | | | (GH-11265) When compiling 3rd party C extensions, the linker flags used by the compiler for the interpreter and the stdlib modules, will get leaked into distutils. In order to avoid that, the PY_CORE_LDFLAGS and PY_LDFLAGS_NODIST are introduced to keep those flags separated. (cherry picked from commit cf10a750f4b50b6775719cfb17bee00bc3a9c60b)

* bpo-35351: Pass link time optimization flags to CFLAGS_NODIST (GH-10797)Miss Islington (bot)2018-12-091-1/+1
| | | | | | | | | When using link time optimizations, the -flto flag is passed to BASECFLAGS, which makes it propagate to distutils. Those flags should be reserved for the interpreter and the stdlib extension modules only, thus moving those flags to CFLAGS_NODIST.

* bpo-28015: Support LTO build with clang (GH-9908) (GH-10922)stratakis2018-12-091-62/+184
| | | | | | | | | | | | | .o generated by clang in LTO mode actually are LLVM bitcode files, which leads to a few errors during configure/build step: - add lto flags to the BASECFLAGS instead of CFLAGS, as CFLAGS are used to build autoconf test case, and some are not compatible with clang LTO (they assume binary in the .o, not bitcode) - force llvm-ar instead of ar, as ar is not aware of .o files generated by clang -flto (cherry picked from commit 5ad36f9b21a3aa3b2265b1b43d73522cc3322df2) Co-authored-by: serge-sans-paille <serge.guelton@telecom-bretagne.eu>

* [3.6] bpo-35214: Initial clang MemorySanitizer support (GH-10479) (GH-10493)Gregory P. Smith2018-11-121-1/+44
| | | | | | | | | | | | | | | | Adds configure flags for msan and ubsan builds to make it easier to enable. These also encode the detail that address sanitizer and memory sanitizer should disable pymalloc. Define MEMORY_SANITIZER when appropriate at build time and adds workarounds to existing code to mark things as initialized where the sanitizer is otherwise unable to determine that. This lets our build succeed under the memory sanitizer. not all tests pass without sanitizer failures yet but we're in pretty good shape after this. (cherry picked from commit 1584a0081500d35dc93ff88e5836df35faf3e3e2) Contributed by Gregory P. Smith [Google LLC] Also includes a whitespace fix from make patchcheck to _posixsubprocess.c - unrelated to the main change that makes the CI happy so I'm just doing it now rather than creating a separate PR.
* [3.6] bpo-31354: Let configure --with-lto work on all builds (GH-10261)stratakis2018-11-071-4/+5
| | | | | | | | | | Allow configure --with-lto to apply to all builds, not just profile-opt builds. Whether this is actually useful or not must be determined by the person building CPython using their own toolchain. My own quick test on x86_64 Debian 9 (gcc 6.3, binutils 2.28) seemed to suggest that it wasn't, but I expect better toolchains can or will exist at some point. The point is to allow it at all.

* bpo-32726: macOS installer changes for 3.6.5Ned Deily2018-03-131-3/+12
| | | | | | | | | | | | | | | | | | | | | | | Backport the new 10.9+ installer variant from 3.7. This variant features more modern options; like 64-bit only (Apple is deprecating 32-bit support in future macOS releases); a built-in version of Tcl/Tk 8.6.8; built with clang rather than gcc-4.2. For 3.6.5, the 10.9+ variant will be offered as an additional alternative to the traditional 10.6+ variant in earlier 3.6.x releases. Binary extension modules (including wheels) built for earlier versions of 3.6.x with the 10.6 variant should continue to work with either 3.6.5 variant without recompilation. In addition, both installer variants have updated 3rd-party libraries: OpenSSL 1.0.2m -> 1.0.2n XZ 5.2.2 -> 5.2.3 SQLite 3.21.0 -> 3.22.0 Also the 10.6 variant now sets CC=gcc instead of CC=gcc-4.2 and does not search for the outdated 10.6 SDK. The variant is built with the same compiler as before. As before, for extension module builds, the CC can be overridden with the CC env variable and an SDK can be specified with the SDKROOT env variable (see man xcrun). These minor changes should be transparent to nearly all users.
