bpo-36722: Debug build loads libraries built in release mode (GH-12952)
In debug build, import now also looks for C extensions compiled in
release mode and for C extensions compiled in the stable ABI.

bpo-36465: Make release and debug ABI compatible (GH-12615)
Release build and debug build are now ABI compatible: the Py_DEBUG
define no longer implies Py_TRACE_REFS define which introduces the
only ABI incompatibility.

A new "./configure --with-trace-refs" build option is now required to
get Py_TRACE_REFS define which adds sys.getobjects() function and
PYTHONDUMPREFS environment variable.

Changes:

* Add ./configure --with-trace-refs
* Py_DEBUG no longer implies Py_TRACE_REFS

bpo-36707: Remove the "m" flag (pymalloc) from SOABI (GH-12931)
"./configure --with-pymalloc" no longer adds the "m" flag to SOABI
(sys.implementation.cache_tag).

Enabling or disabling pymalloc has no impact on the ABI.

bpo-36618: Don't add -fmax-type-align flag to old clang (GH-12811) 2019-04-13 00:51:07 +02:00
Victor Stinner 23a683adf8
bpo-36618: Add -fmax-type-align=8 flag for clang (GH-12809)
Add -fmax-type-align=8 to CFLAGS when clang compiler is detected.

The pymalloc memory allocator aligns memory on 8 bytes. On x86-64,
clang expects alignment on 16 bytes by default and so uses MOVAPS
instruction which can lead to segmentation fault. Instruct clang that
Python is limited to alignemnt on 8 bytes to use MOVUPS instruction
instead: slower but don't trigger a SIGSEGV if the memory is not
aligned on 16 bytes.

Sadly, the flag must be expected to CFLAGS and not just
CFLAGS_NODIST, since third party C extensions can have the same
issue.

Michael Felt 9d949f7796 bpo-36588: On AIX, remove major version from sys.platform (GH-12787)
On AIX, sys.platform doesn't contain the major version anymore.
Always return 'aix', instead of 'aix3' .. 'aix7'.  Since
older Python versions include the version number, it is recommended to
always use sys.platform.startswith('aix').

ngie-eign 90c6facebd closes bpo-13497: Fix `broken nice` configure test. (GH-12041)
Per POSIX, `nice(3)` requires `unistd.h` and `exit(3)` requires `stdlib.h`.

bpo-35903: Use autoconfig to probe for shm_open() and shm_unlink(). (#11765)
Use autoconfig to probe for shm_open() and shm_unlink().  Set SHM_NEEDS_LIBRT if we must
link with librt to get the shm_* functions.  Change setup.py to use the autoconfig defines.  These
changes should make it more likely that _multiprocessing/posixshmem.c gets built correctly on
different platforms.

bpo-28503: Use crypt_r() when available instead of crypt() (GH-11373)
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.

stratakis cf10a750f4 bpo-35257: Avoid leaking LTO linker flags into distutils (GH-10900)
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.

stratakis f92c7aa1ae bpo-35351: Pass link time optimization flags to CFLAGS_NODIST (GH-10797)
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-35214: Initial clang MemorySanitizer support (GH-10479)
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.

serge-sans-paille 5ad36f9b21 bpo-28015: Support LTO build with clang (GH-9908)
.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

Ross Burton 2a9c3805dd closes bpo-34585: Don't do runtime test to get float byte order. (GH-9085)
Currently configure.ac uses AC_RUN_IFELSE to determine the byte order of doubles, but this silently fails under cross compilation and Python doesn't do floats properly.

Instead, steal a macro from autoconf-archive which compiles code using magic doubles (which encode to ASCII) and grep for the representation in the binary.

RFC because this doesn't yet handle the weird ancient ARMv4 OABI 'mixed-endian' encoding properly. This encoding is ancient and I don't believe the union of "Python 3.8 users" and "OABI users" has anything in. Should the support for this just be dropped too? Alternatively, someone will need to find an OABI toolchain to verify the encoding of the magic double.

FreeBSD since the system compiler is used by default (cc)

bpo-32726: macOS installer and framework enhancements and changes for 3.7.0 (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)
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.

INADA Naoki 6b42eb1764 bpo-29585: Fix sysconfig.get_config_var("PYTHONFRAMEWORK") (GH-2483)
`PYTHONFRAMEWORK` is defined in `Makefile` and it shoulnd't be used
in `pyconfig.h`.

`sysconfig.py --generate-posix-vars` reads config vars from Makefile
and `pyconfig.h`.  Conflicting variables should be avoided.

Especially, string config variables in Makefile are unquoted, but
in `pyconfig.h` are keep quoted.  So it should be private (starts with
underscore).

Victor Stinner a5c62a8e9f bpo-23404: make touch becomes make regen-all (#1405)
Don't rebuild generated files based on file modification time
anymore, the action is now explicit. Replace "make touch"
with "make regen-all".

Changes:

* Remove "make touch", Tools/hg/hgtouch.py and .hgtouch
* Add a new "make regen-all" command to rebuild all generated files
* Add subcommands to only generate specific files:

  - regen-ast: Include/Python-ast.h and Python/Python-ast.c
  - regen-grammar: Include/graminit.h and Python/graminit.c
  - regen-importlib: Python/importlib_external.h and Python/importlib.h
  - regen-opcode: Include/opcode.h
  - regen-opcode-targets: Python/opcode_targets.h
  - regen-typeslots: Objects/typeslots.inc

* Rename PYTHON_FOR_GEN to PYTHON_FOR_REGEN
* pgen is now only built by by "make regen-grammar"
* Add $(srcdir)/ prefix to paths to source files to handle correctly
  compilation outside the source directory

Note: $(PYTHON_FOR_REGEN) is no more used nor needed by "make"
default target building Python.

Alex Wang 8cea5929f5 bpo-29643: Fix check for --enable-optimizations (GH-129)

resulting in the ``--enable-optimizations`` flag being effectively ignored.

Alex Dzyoba 8a543c0bc7 `make tags` fixes (GH-717)
* Fix `make tags` warnings

`make tags` target tries to find C sources and headers in "Grammar" and
"Mac" folders and generates these warnings:

    ctags: Warning: cannot open source file "Grammar/*.[ch]" : No such file or directory
    ctags: Warning: cannot open source file "Mac/*.[ch]" : No such file or directory

This commit changes $SRCDIRS variable in configure.ac to remote these
directories. This variable is used only for tags generation.

Also, "configure" was regenerated with `autoreconf`.

* Fix `make tags` fail on non-default tag names

When ctags overrides default tags filename (e.g. `-f .tags`) `make tags`
is failed because it assumes to see default `tags` filename:

    sort: cannot read: tags: No such file or directory

This commit explicitly specifies "tags" filename for tags generation.
