From 7d87aea63fb7387b88b7fd8057feb9e42e53bd8c Mon Sep 17 00:00:00 2001 From: Quincey Koziol Date: Thu, 19 Dec 2019 22:41:37 -0600 Subject: Refactor all the 'H5VL_*_optional' callbacks to move the type of operation out of the va_list, so it's at least possible for another connector to know what the operation is and decide whether to implement it or not. Added a new VOL sub-class called "introspect" where callbacks that report information about the connector or container can be placed. Added an 'opt_query' callback to this sub-class, for a connector to report back to the library whether a particular optional callback operation is supported. Also added a 'get_conn_cls' introspection callback, to retrieve the H5VL_class_t of a connector (either the "current" connector, H5VL_GET_CONN_LVL_CURR, or the terminal connector, H5VL_GET_CONN_LVL_TERM). Moved the "post open" operation from a file 'specific' operation to a file 'optional' operation, now that it's possible to detect (with the 'opt_query' introspection callback) whether a VOL connector implements an optional operation, without just returning an error. Added new internal VOL helper routines: H5VL_object_is_native, to determine if an object is in (or is a) native file, and H5VL_file_is_same, to determine if two objects are in (or are) the same terminal VOL connector's container. (And moved the special handling for FILE_IS_EQUAL operation out of internal VOL callback routine into H5VL_file_is_same) Made new dataset 'get' operation for H5Dvlen_get_buf_size, aligning it better with other 'get' operations in API. Fixed several issues with pass-through connectors, which are now passing the 'make check-passthrough-vol' tests again. A bunch of warning and style cleanups as well. --- MANIFEST | 1 + bin/trace | 11 + src/CMakeLists.txt | 1 + src/H5Adeprec.c | 4 +- src/H5D.c | 124 +- src/H5Dchunk.c | 119 +- src/H5Dint.c | 182 ++- src/H5Dio.c | 4 +- src/H5Dpkg.h | 15 +- src/H5F.c | 101 +- src/H5FDhdfs.c | 22 +- src/H5Fdeprec.c | 10 +- src/H5Fint.c | 18 +- src/H5Fmpi.c | 12 +- src/H5Gdeprec.c | 16 +- src/H5HG.c | 2 +- src/H5HGprivate.h | 2 +- src/H5I.c | 15 +- src/H5Itest.c | 2 +- src/H5M.c | 40 +- src/H5O.c | 32 +- src/H5Odeprec.c | 6 +- src/H5Oint.c | 1 + src/H5Rdeprec.c | 42 +- src/H5Rint.c | 93 +- src/H5Tconv.c | 33 +- src/H5Tref.c | 281 +++-- src/H5Tvlen.c | 6 +- src/H5VLcallback.c | 2717 +++++++++++++++++++++++------------------- src/H5VLconnector.h | 99 +- src/H5VLconnector_passthru.h | 37 +- src/H5VLint.c | 154 ++- src/H5VLnative.c | 38 +- src/H5VLnative.h | 90 +- src/H5VLnative_attr.c | 8 +- src/H5VLnative_blob.c | 2 +- src/H5VLnative_dataset.c | 21 +- src/H5VLnative_file.c | 28 +- src/H5VLnative_group.c | 6 +- src/H5VLnative_introspect.c | 52 + src/H5VLnative_object.c | 5 +- src/H5VLnative_private.h | 26 +- src/H5VLpassthru.c | 398 ++++--- src/H5VLprivate.h | 42 +- src/H5VLpublic.h | 5 +- src/H5trace.c | 406 ++++++- src/Makefile.am | 2 +- test/null_vol_connector.c | 4 + test/trefer.c | 36 +- test/vol.c | 4 + 50 files changed, 3348 insertions(+), 2027 deletions(-) create mode 100644 src/H5VLnative_introspect.c diff --git a/MANIFEST b/MANIFEST index 7e1dbd7..e2fcb53 100644 --- a/MANIFEST +++ b/MANIFEST @@ -937,6 +937,7 @@ ./src/H5VLnative_file.c ./src/H5VLnative_group.c ./src/H5VLnative_link.c +./src/H5VLnative_introspect.c ./src/H5VLnative_object.c ./src/H5VLnative_private.h ./src/H5VLpassthru.c diff --git a/bin/trace b/bin/trace index 34bcd3a..50fd2f3 100755 --- a/bin/trace +++ b/bin/trace @@ -100,24 +100,35 @@ $Source = ""; "H5T_str_t" => "Tz", "unsigned long" => "Ul", "unsigned long long" => "UL", + "H5VL_subclass_t" => "VS", + "H5VL_get_conn_lvl_t" => "VL", "H5VL_attr_get_t" => "Va", + "H5VL_attr_optional_t" => "Vs", "H5VL_attr_specific_t" => "Vb", "H5VL_blob_specific_t" => "VB", "H5VL_class_value_t" => "VC", "H5VL_dataset_get_t" => "Vc", "H5VL_dataset_specific_t" => "Vd", + "H5VL_dataset_optional_t" => "Vt", "H5VL_datatype_get_t" => "Ve", "H5VL_datatype_specific_t" => "Vf", + "H5VL_datatype_optional_t" => "Vu", "H5VL_file_get_t" => "Vg", "H5VL_file_specific_t" => "Vh", + "H5VL_file_optional_t" => "Vv", "H5VL_group_get_t" => "Vi", "H5VL_group_specific_t" => "Vj", + "H5VL_group_optional_t" => "Vw", "H5VL_link_create_type_t" => "Vk", "H5VL_link_get_t" => "Vl", "H5VL_link_specific_t" => "Vm", + "H5VL_link_optional_t" => "Vx", "H5VL_object_get_t" => "Vn", "H5VL_object_specific_t" => "Vo", + "H5VL_object_optional_t" => "Vy", "H5VL_request_specific_t" => "Vr", + "H5VL_request_optional_t" => "Vz", + "H5VL_blob_optional_t" => "VA", "void" => "x", "FILE" => "x", "H5A_operator_t" => "x", diff --git a/src/CMakeLists.txt b/src/CMakeLists.txt index c794c1a..4b020fa 100644 --- a/src/CMakeLists.txt +++ b/src/CMakeLists.txt @@ -657,6 +657,7 @@ set (H5VL_SOURCES ${HDF5_SRC_DIR}/H5VLnative_file.c ${HDF5_SRC_DIR}/H5VLnative_group.c ${HDF5_SRC_DIR}/H5VLnative_link.c + ${HDF5_SRC_DIR}/H5VLnative_introspect.c ${HDF5_SRC_DIR}/H5VLnative_object.c ${HDF5_SRC_DIR}/H5VLpassthru.c ) diff --git a/src/H5Adeprec.c b/src/H5Adeprec.c index 8d0e33c..b85e435 100644 --- a/src/H5Adeprec.c +++ b/src/H5Adeprec.c @@ -334,7 +334,7 @@ H5Aget_num_attrs(hid_t loc_id) HGOTO_ERROR(H5E_ARGS, H5E_BADTYPE, (-1), "invalid location identifier") /* Get the number of attributes for the object */ - if(H5VL_object_optional(vol_obj, H5P_DATASET_XFER_DEFAULT, H5_REQUEST_NULL, H5VL_NATIVE_OBJECT_GET_INFO, &loc_params, &oinfo, H5O_INFO_ALL) < 0) + if(H5VL_object_optional(vol_obj, H5VL_NATIVE_OBJECT_GET_INFO, H5P_DATASET_XFER_DEFAULT, H5_REQUEST_NULL, &loc_params, &oinfo, H5O_INFO_ALL) < 0) HGOTO_ERROR(H5E_ATTR, H5E_CANTGET, (-1), "unable to get attribute count for object") H5_CHECKED_ASSIGN(ret_value, int, oinfo.num_attrs, hsize_t); @@ -399,7 +399,7 @@ H5Aiterate1(hid_t loc_id, unsigned *attr_num, H5A_operator1_t op, void *op_data) HGOTO_ERROR(H5E_VOL, H5E_BADTYPE, H5_ITER_ERROR, "invalid location identifier") /* Call attribute iteration routine */ - if((ret_value = H5VL_attr_optional(vol_obj, H5P_DATASET_XFER_DEFAULT, H5_REQUEST_NULL, H5VL_NATIVE_ATTR_ITERATE_OLD, loc_id, attr_num, op, op_data)) < 0) + if((ret_value = H5VL_attr_optional(vol_obj, H5VL_NATIVE_ATTR_ITERATE_OLD, H5P_DATASET_XFER_DEFAULT, H5_REQUEST_NULL, loc_id, attr_num, op, op_data)) < 0) HERROR(H5E_VOL, H5E_BADITER, "error iterating over attributes"); done: diff --git a/src/H5D.c b/src/H5D.c index 7c68127..ce2b832 100644 --- a/src/H5D.c +++ b/src/H5D.c @@ -717,14 +717,6 @@ done: * VL data, in memory.
