* bpo-34602: Avoid failures setting macOS stack resource limit (GH-14546)Miss Islington (bot)2019-07-021-0/+6
| | | | | | | | | | | | | | | | | | | | 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.

* bpo-28503: Use crypt_r() when available instead of crypt() (GH-11373) (GH-11376)Miss Islington (bot)2018-12-301-0/+144
| | | | | | | | Use crypt_r() when available instead of crypt() in the crypt module. As a nice side effect: This also avoids a memory sanitizer flake as clang msan doesn't know about crypt's internal libc allocated buffer.

* bpo-35257: Avoid leaking LTO linker flags into distutils (GH-10900) (GH-11264)Victor Stinner2018-12-201-1/+3
| | | | | | | | 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)2018-12-041-1/+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.

* [3.7] bpo-35214: Initial clang MemorySanitizer support (GH-10479) (GH-10492)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.

* bpo-28015: Support LTO build with clang (GH-9908)Miss Islington (bot)2018-10-241-62/+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>

* bpo-32726: macOS installer and framework enhancements and changes for 3.7.0 ↵Ned Deily2018-01-301-3/+12
| | | | | | | | | | | | | | (GH-5448) This issue covers various changes for the macOS installers provided via python.org for 3.7.0. - Provide a provisional new installer variant for macOS 10.9 and later systems with 64-bit (x86_64) architecture only. Apple has made it known that future versions of macOS will only fully support 64-bit executables and some other third-party software suppliers have chosen 10.9 as their oldest supported system. - Support **Tcl/Tk 8.6** with the 10.9 installer variant. - Upgrade **OpenSSL** to 1.1.0g and **SQLite** to 3.22.0. - The compiler name used for the interpreter build and for modules built with **Distutils / pip** is now _gcc_ rather than _gcc-4.2_. And extension module builds will no longer try to force use of an old SDK if present.
* bpo-31429: Define TLS cipher suite on build time (#3532)Christian Heimes2018-01-291-0/+48
| | | | | | | | | | | | | Until now Python used a hard coded white list of default TLS cipher suites. The old approach has multiple downsides. OpenSSL's default selection was completely overruled. Python did neither benefit from new cipher suites (ChaCha20, TLS 1.3 suites) nor blacklisted cipher suites. For example we used to re-enable 3DES. Python now defaults to OpenSSL DEFAULT cipher suite selection and black lists all unwanted ciphers. Downstream vendors can override the default cipher list with --with-ssl-default-suites.

| | | | | | | | | | | | | | Add https://www.gnu.org/software/autoconf-archive/ax_check_openssl.html to auto-detect compiler flags, linker flags and libraries to compile OpenSSL extensions.

| | | | | | | | | | | | (RFC4122) (#4974) Starting with AIX6.1 there is support in libc.a for uuid (RFC4122) This patch provides the changes needed for this integration with the OS. On AIX the base function is uuid_create() rather than uuid_generate_time() The AIX uuid_t typedef is more aligned to the UUID field based definition while the Linux typedef that is more aligned with UUID bytes (or perhaps UUID bytes_le) definitions.
