This series is based on next.\n\nIncluded in this series are conversions for find_unique_abbrev and\nlookup_replace_object, as well as parts of the sha1_file code.\n\nConflicts with pu are average in number but minor, mostly because of the\ntype_name conversion. None of them are tricky, except that the\nintroduction of get_tree_entry_if_blob requires a conversion of that\nfunction.\n\nbrian m. carlson (36):\n bulk-checkin: convert index_bulk_checkin to struct

Introduce temporaries to convert the return\nvalues of lookup_replace_object and lookup_replace_object_extended into\nstruct object_id.\n\nThe temporaries are needed because in order to convert\nlookup_replace_object, open_istream needs to be converted, and\nopen_istream needs check_sha1_signature to be converted, causing a loop\nof dependencies. The temporaries will be removed in a future patch.\n\nSigned-off-by: brian m. carlson \n---\n builtin/fast-export.c | 2 +-\n builtin/index-pack.c | 2 +-\n builtin/mktag.c | 5 ++++-\n cache.h | 2 +-\n object.c | 10 ++++++++--\n pack-check.c | 4 ++--\n sha1_file.c | 12 ++++++------\n 7 files changed, 23 insertions(+), 14 deletions(-)\n\ndiff --git a/builtin/fast-export.c b/builtin/fast-export.c\nindex 796d0cd66c..293a6615fa 100644\n--- a/builtin/fast-export.c\n+++ b/builtin/fast-export.c\n@@ -240,7 +240,7 @@ static void export_blob(const struct object_id *oid)\n \t\tbuf = read_sha1_file(oid->hash, &type, &size);\n \t\tif (!buf)\n \t\t\tdie (\"Could not read blob %s\", oid_to_hex(oid));\n-\t\tif (check_sha1_signature(oid->hash, buf, size, typename(type)) < 0)\n+\t\tif (check_object_signature(oid, buf, size, typename(type)) < 0)\n \t\t\tdie(\"sha1 mismatch in blob %s\", oid_to_hex(oid));\n \t\tobject = parse_object_buffer(oid, type, size, buf, &eaten);\n \t}\ndiff --git a/builtin/index-pack.c b/builtin/index-pack.c\nindex 5c7ab47c36..e0a776f1ac 100644\n--- a/builtin/index-pack.c\n+++ b/builtin/index-pack.c\n@@ -1377,7 +1377,7 @@ static void fix_unresolved_deltas(struct hashfile *f)\n \t\tif (!base_obj->data)\n \t\t\tcontinue;\n \n-\t\tif (check_sha1_signature(d->oid.hash, base_obj->data,\n+\t\tif (check_object_signature(&d->oid, base_obj->data,\n \t\t\t\tbase_obj->size, typename(type)))\n \t\t\tdie(_(\"local object %s is corrupt\"), oid_to_hex(&d->oid));\n \t\tbase_obj->obj = append_obj_to_pack(f, d->oid.hash,\ndiff --git a/builtin/mktag.c b/builtin/mktag.c\nindex 65bb41e3cd..810b24bef3 100644\n--- a/builtin/mktag.c\n+++ b/builtin/mktag.c\n@@ -27,8 +27,11 @@ static int verify_object(const struct object_id *oid, const char *expected_type)\n \tconst unsigned char *repl = lookup_replace_object(oid->hash);\n \n \tif (buffer) {\n+\t\tstruct object_id reploid;\n+\t\thashcpy(reploid.hash, repl);\n+\n \t\tif (type == type_from_string(expected_type))\n-\t\t\tret = check_sha1_signature(repl, buffer, size, expected_type);\n+\t\t\tret = check_object_signature(&reploid, buffer, size, expected_type);\n \t\tfree(buffer);\n \t}\n \treturn ret;\ndiff --git a/cache.h b/cache.h\nindex 8a9055f4e7..f29ff43bbd 100644\n--- a/cache.h\n+++ b/cache.h\n@@ -1236,7 +1236,7 @@ extern void *map_sha1_file(const unsigned char *sha1, unsigned long *size);\n extern int unpack_sha1_header(git_zstream *stream, unsigned char *map, unsigned long mapsize, void *buffer, unsigned long bufsiz);\n extern int parse_sha1_header(const char *hdr, unsigned long *sizep);\n \n-extern int check_sha1_signature(const unsigned char *sha1, void *buf, unsigned long size, const char *type);\n+extern int check_object_signature(const struct object_id *oid, void *buf, unsigned long size, const char *type);\n \n extern int finalize_object_file(const char *tmpfile, const char *filename);\n \ndiff --git a/object.c b/object.c\nindex 9e6f9ff20b..c63f02a40f 100644\n--- a/object.c\n+++ b/object.c\n@@ -255,7 +255,10 @@ struct object *parse_object(const struct object_id *oid)\n \tif ((obj && obj->type == OBJ_BLOB && has_object_file(oid)) ||\n \t (!obj && has_object_file(oid) &&\n \t sha1_object_info(oid->hash, NULL) == OBJ_BLOB)) {\n-\t\tif (check_sha1_signature(repl, NULL, 0, NULL) < 0) {\n+\t\tstruct object_id reploid;\n+\t\thashcpy(reploid.hash, repl);\n+\n+\t\tif (check_object_signature(&reploid, NULL, 0, NULL) < 0) {\n \t\t\terror(\"sha1 mismatch %s\", oid_to_hex(oid));\n \t\t\treturn NULL;\n \t\t}\n@@ -265,7 +268,10 @@ struct object *parse_object(const struct object_id *oid)\n \n \tbuffer = read_sha1_file(oid->hash, &type, &size);\n \tif (buffer) {\n-\t\tif (check_sha1_signature(repl, buffer, size, typename(type)) < 0) {\n+\t\tstruct object_id reploid;\n+\t\thashcpy(reploid.hash, repl);\n+\n+\t\tif (check_object_signature(&reploid, buffer, size, typename(type)) < 0) {\n \t\t\tfree(buffer);\n \t\t\terror(\"sha1 mismatch %s\", sha1_to_hex(repl));\n \t\t\treturn NULL;\ndiff --git a/pack-check.c b/pack-check.c\nindex 403a572567..80ef7c1c63 100644\n--- a/pack-check.c\n+++ b/pack-check.c\n@@ -126,7 +126,7 @@ static int verify_packfile(struct packed_git *p,\n \n \t\tif (type == OBJ_BLOB && big_file_threshold <= size) {\n \t\t\t/*\n-\t\t\t * Let check_sha1_signature() check it with\n+\t\t\t * Let check_object_signature() check it with\n \t\t\t * the streaming interface;
