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. files: A Misc/NEWS.d/next/Core and Builtins/2017-12-22-13-38-17.bpo-32399.wlH12z.rst M Modules/_uuidmodule.c M configure M configure.ac M pyconfig.h.in diff --git a/Misc/NEWS.d/next/Core and Builtins/2017-12-22-13-38-17.bpo-32399.wlH12z.rst b/Misc/NEWS.d/next/Core and Builtins/2017-12-22-13-38-17.bpo-32399.wlH12z.rst new file mode 100644 index 00000000000..ab18f268c81 --- /dev/null +++ b/Misc/NEWS.d/next/Core and Builtins/2017-12-22-13-38-17.bpo-32399.wlH12z.rst @@ -0,0 +1 @@ +Add AIX uuid library support for RFC4122 using uuid_create() in libc.a diff --git a/Modules/_uuidmodule.c b/Modules/_uuidmodule.c index d4bc3c7b0d4..1b37511c228 100644 --- a/Modules/_uuidmodule.c +++ b/Modules/_uuidmodule.c @@ -1,22 +1,33 @@ #define PY_SSIZE_T_CLEAN #include "Python.h" +#ifdef HAVE_UUID_UUID_H #include <uuid/uuid.h> +#endif +#ifdef HAVE_UUID_H +#include <uuid.h> +#endif static PyObject * py_uuid_generate_time_safe(void) { + uuid_t uuid; #ifdef HAVE_UUID_GENERATE_TIME_SAFE - uuid_t out; int res; - res = uuid_generate_time_safe(out); - return Py_BuildValue("y#i", (const char *) out, sizeof(out), res); + res = uuid_generate_time_safe(uuid); + return Py_BuildValue("y#i", (const char *) uuid, sizeof(uuid), res); +#elif HAVE_UUID_CREATE +/* + * AIX support for uuid - RFC4122 + */ + unsigned32 status; + uuid_create(&uuid, &status); + return Py_BuildValue("y#i", (const char *) &uuid, sizeof(uuid), (int) status); #else - uuid_t out; - uuid_generate_time(out); - return Py_BuildValue("y#O", (const char *) out, sizeof(out), Py_None); + uuid_generate_time(uuid); + return Py_BuildValue("y#O", (const char *) uuid, sizeof(uuid), Py_None); #endif } diff --git a/configure b/configure index 2728f67b577..da2c43fe7a2 100755 --- a/configure +++ b/configure @@ -9516,6 +9516,21 @@ _ACEOF fi # Dynamic linking for HP-UX +# checks for uuid.h location +for ac_header in uuid/uuid.h uuid.h +do : + as_ac_Header=`$as_echo "ac_cv_header_$ac_header" | $as_tr_sh` +ac_fn_c_check_header_mongrel "$LINENO" "$ac_header" "$as_ac_Header" "$ac_includes_default" +if eval test \"x\$"$as_ac_Header"\" = x"yes"; then : + cat >>confdefs.h <<_ACEOF +#define `$as_echo "HAVE_$ac_header" | $as_tr_cpp` 1 +_ACEOF + +fi + +done + + { $as_echo "$as_me:${as_lineno-$LINENO}: checking for uuid_generate_time_safe" >&5 $as_echo_n "checking for uuid_generate_time_safe...
