commit a49d154f4a8e493baf2296a15c7b5c56cd25e993 Author: Florian Weimer Date: Wed Dec 20 14:59:19 2023 +0100 pybind: Fix C type errors in Cython-generated Python bindings Several Ceph APIs use bool * types, which correspond to libcpp.bool * types in Cython. The bint type has an incorrect size 4 and cannot be used as a replacement. This prevents a compilation failure with future compilers: …-build/src/pybind/rbd/rbd.c: In function ‘__pyx_pf_3rbd_3RBD_104namespace_exists’: …-build/src/pybind/rbd/rbd.c:42165:76: error: passing argument 3 of ‘rbd_namespace_exists’ from incompatible pointer type 42165 | __pyx_v_ret = rbd_namespace_exists(__pyx_v__ioctx, __pyx_v__name, (&__pyx_v__exists)); | ~^~~~~~~~~~~~~~~~~ | | | int * In file included from …-build/src/pybind/rbd/rbd.c:1268: …/src/include/rbd/librbd.h:1496:45: note: expected ‘_Bool *’ but argument is of type ‘int *’ 1496 | bool *exists); | ^ Signed-off-by: Florian Weimer diff --git a/src/pybind/rbd/c_rbd.pxd b/src/pybind/rbd/c_rbd.pxd index 885f7bd46a..bda23bbc47 100644 --- a/src/pybind/rbd/c_rbd.pxd +++ b/src/pybind/rbd/c_rbd.pxd @@ -2,6 +2,7 @@ from libc.stdint cimport * from ctime cimport time_t, timespec +cimport libcpp cdef extern from "rados/librados.h": enum: @@ -525,7 +526,7 @@ cdef extern from "rbd/librbd.h" nogil: int rbd_snap_unprotect(rbd_image_t image, const char *snap_name) int rbd_snap_is_protected(rbd_image_t image, const char *snap_name, int *is_protected) - int rbd_snap_exists(rbd_image_t image, const char *snapname, bint *exists) + int rbd_snap_exists(rbd_image_t image, const char *snapname, libcpp.bool *exists) int rbd_snap_get_limit(rbd_image_t image, uint64_t *limit) int rbd_snap_set_limit(rbd_image_t image, uint64_t limit) int rbd_snap_get_timestamp(rbd_image_t image, uint64_t snap_id, timespec *timestamp) @@ -711,7 +712,7 @@ cdef extern from "rbd/librbd.h" nogil: int rbd_namespace_list(rados_ioctx_t io, char *namespace_names, size_t *size) int rbd_namespace_exists(rados_ioctx_t io, const char *namespace_name, - bint *exists) + libcpp.bool *exists) int rbd_pool_init(rados_ioctx_t, bint force) diff --git a/src/pybind/rbd/mock_rbd.pxi b/src/pybind/rbd/mock_rbd.pxi index 11872bd814..364f965fba 100644 --- a/src/pybind/rbd/mock_rbd.pxi +++ b/src/pybind/rbd/mock_rbd.pxi @@ -3,6 +3,11 @@ from libc.stdint cimport * from ctime cimport time_t, timespec +# Make the bool type available as libcpp.bool, for both C and C++. +cimport libcpp +cdef extern from "": + pass + cdef nogil: enum: _LIBRADOS_SNAP_HEAD "LIBRADOS_SNAP_HEAD" @@ -637,7 +642,7 @@ cdef nogil: int rbd_snap_is_protected(rbd_image_t image, const char *snap_name, int *is_protected): pass - int rbd_snap_exists(rbd_image_t image, const char *snapname, bint *exists): + int rbd_snap_exists(rbd_image_t image, const char *snapname, libcpp.bool *exists): pass int rbd_snap_get_limit(rbd_image_t image, uint64_t *limit): pass @@ -896,7 +901,7 @@ cdef nogil: size_t *size): pass int rbd_namespace_exists(rados_ioctx_t io, const char *namespace_name, - bint *exists): + libcpp.bool *exists): pass int rbd_pool_init(rados_ioctx_t io, bint force): pass diff --git a/src/pybind/rbd/rbd.pyx b/src/pybind/rbd/rbd.pyx index fcb2fb3470..f59ba23f0f 100644 --- a/src/pybind/rbd/rbd.pyx +++ b/src/pybind/rbd/rbd.pyx @@ -23,6 +23,7 @@ from libc cimport errno from libc.stdint cimport * from libc.stdlib cimport malloc, realloc, free from libc.string cimport strdup, memset +cimport libcpp try: from collections.abc import Iterable @@ -1935,12 +1936,12 @@ class RBD(object): cdef: rados_ioctx_t _ioctx = convert_ioctx(ioctx) const char *_name = name - bint _exists = False + libcpp.bool _exists = False with nogil: ret = rbd_namespace_exists(_ioctx, _name, &_exists) if ret != 0: raise make_ex(ret, 'error verifying namespace') - return bool(_exists != 0) + return _exists def namespace_list(self, ioctx): """ @@ -3679,12 +3680,12 @@ cdef class Image(object): name = cstr(name, 'name') cdef: char *_name = name - bint _exists = False + libcpp.bool _exists = False with nogil: ret = rbd_snap_exists(self.image, _name, &_exists) if ret != 0: raise make_ex(ret, 'error getting snapshot exists for %s' % self.name) - return bool(_exists != 0) + return _exists @requires_not_closed def get_snap_limit(self): diff --git a/src/pybind/rgw/mock_rgw.pxi b/src/pybind/rgw/mock_rgw.pxi index ca893a5bb8..806d4df75d 100644 --- a/src/pybind/rgw/mock_rgw.pxi +++ b/src/pybind/rgw/mock_rgw.pxi @@ -1,5 +1,10 @@ # cython: embedsignature=True +# Make the bool type available as libcpp.bool, for both C and C++. +cimport libcpp +cdef extern from "": + pass + cdef nogil: ctypedef void* librgw_t @@ -111,8 +116,8 @@ cdef nogil: int rgw_readdir(rgw_fs *fs, rgw_file_handle *parent_fh, uint64_t *offset, - bint (*cb)(const char *name, void *arg, uint64_t offset, stat *st, uint32_t st_mask, uint32_t flags) nogil except?
