…gs. (#148193) The Generator._make_boundary regex did not match on boundary phrases correctly when using CRLF line endings due to re.MULTILINE not considering \r\n as a line ending.
…133313) This option changes the behavior of --enable-shared to continue to build the libpython3.x.so shared library, but not use it for linking the python3 interpreter executable. Instead, the executable is linked directly against the libpython .o files as it would be with --disable-shared. There are two benefits of this change. First, libpython uses thread-local storage, which is noticeably slower when used in a loaded module instead of in the main program, because the main program can take advantage of constant offsets from the thread state pointer but loaded modules have to dynamically call a function __tls_get_addr() to potentially allocate their thread-local storage area. (There is another thread-local storage model for dynamic libraries which mitigates most of this performance hit, but it comes at the cost of preventing dlopen("libpython3.x.so"), which is a use case we want to preserve.) Second, this improves the user experience around relocatable Python a little bit, in that we don't need to use an $ORIGIN-relative path to locate libpython3.x.so, which has some mild benefits around musl (which does not support $ORIGIN-relative DT_NEEDED, only $ORIGIN-relative DT_RPATH/DT_RUNPATH), users who want to make the interpreter setuid or setcap (which prevents processing $ORIGIN), etc.
