commit 6934d8276a5597290aa75da9690021b694ce66e3 from: Omar Polo date: Mon Aug 12 22:24:39 2024 UTC rename idlen to digest_{,string_}len In my early sha256 work I've used `idlen' to parametrize the digest length, but that's ambiguous since it could refer either to the digest length (in binary form) or the digest _string_ length (hexadecimal). So, change the few offenders to either digest_len or digest_string_len, which is a "naming scheme" I've already used in the rest of the tree. ok stsp@ commit - 05f7204b7c26d432547753965bf1a27fb7fb2e01 commit + 6934d8276a5597290aa75da9690021b694ce66e3 blob - b6b4541f9756fd1fc9eb3329cd32a375b2a4b874 blob + 251cdbaaf18885bef299a7edee1e4be43a305857 --- lib/got_lib_object_parse.h +++ lib/got_lib_object_parse.h @@ -31,7 +31,7 @@ struct got_parsed_tree_entry { size_t namelen; /* strlen(name) */ mode_t mode; /* Mode parsed from tree buffer. */ uint8_t *id; /* Points to ID in parsed tree buffer. */ - size_t idlen; + size_t digest_len; int algo; }; const struct got_error *got_object_parse_tree_entry( blob - 0527d5d744aafecf3256df577f428320a5aa716d blob + 6d3cc02388107ba9636418a37dd0a10e66670f94 --- lib/object_open_io.c +++ lib/object_open_io.c @@ -567,7 +567,7 @@ open_tree(struct got_tree_object **tree, err = got_error(GOT_ERR_NO_SPACE); goto done; } - memcpy(te->id.hash, pe->id, pe->idlen); + memcpy(te->id.hash, pe->id, pe->digest_len); te->id.algo = pe->algo; te->mode = pe->mode; te->idx = i; blob - 13da36f4db4623f60a2b68897885e715fba89ba1 blob + 35db86beeeb7e5e79780d56b6c7304fd4eefe51f --- lib/object_parse.c +++ lib/object_parse.c @@ -764,7 +764,7 @@ got_object_tree_close(struct got_tree_object *tree) const struct got_error * got_object_parse_tree_entry(struct got_parsed_tree_entry *pte, size_t *elen, - char *buf, size_t maxlen, size_t idlen, enum got_hash_algorithm algo) + char *buf, size_t maxlen, size_t digest_len, enum got_hash_algorithm algo) { char *p, *space; @@ -788,16 +788,16 @@ got_object_parse_tree_entry(struct got_parsed_tree_ent p++; } - if (*elen > maxlen || maxlen - *elen < idlen) + if (*elen > maxlen || maxlen - *elen < digest_len) return got_error(GOT_ERR_BAD_OBJ_DATA); pte->name = space + 1; pte->namelen = strlen(pte->name); buf += *elen; pte->id = buf; - pte->idlen = idlen; + pte->digest_len = digest_len; pte->algo = algo; - *elen += idlen; + *elen += digest_len; return NULL; } blob - 480a6f9d0e7a60f9920ec458ea66f95802e59079 blob + 8dc9adc210203ebedb74801ccf880e731d62df8b --- lib/pack.c +++ lib/pack.c @@ -78,12 +78,12 @@ got_packidx_init_hdr(struct got_packidx *p, int verify struct got_packidx_v2_hdr *h; struct got_hash ctx; uint8_t hash[GOT_HASH_DIGEST_MAXLEN]; - size_t nobj, len_fanout, len_ids, offset, remain, idlen; + size_t nobj, len_fanout, len_ids, offset, remain, digest_string_len; ssize_t n; int i; got_hash_init(&ctx, p->algo); - idlen = got_hash_digest_length(p->algo); + digest_string_len = got_hash_digest_length(p->algo); h = &p->hdr; offset = 0; @@ -303,31 +303,34 @@ got_packidx_init_hdr(struct got_packidx *p, int verify offset += p->nlargeobj * sizeof(*h->large_offsets); checksum: - if (remain < idlen * 2) { + if (remain < digest_string_len * 2) { err = got_error(GOT_ERR_BAD_PACKIDX); goto done; } if (p->map) { - memcpy(h->trailer.packfile_hash, p->map + offset, idlen); - memcpy(h->trailer.packidx_hash, p->map + offset + idlen, idlen); + memcpy(h->trailer.packfile_hash, p->map + offset, + digest_string_len); + memcpy(h->trailer.packidx_hash, + p->map + offset + digest_string_len, digest_string_len); } else { - n = read(p->fd, h->trailer.packfile_hash, idlen); + n = read(p->fd, h->trailer.packfile_hash, digest_string_len); if (n < 0) err = got_error_from_errno("read"); - else if (n != idlen) { + else if (n != digest_string_len) { err = got_error(GOT_ERR_BAD_PACKIDX); goto done; } - n = read(p->fd, h->trailer.packidx_hash, idlen); + n = read(p->fd, h->trailer.packidx_hash, digest_string_len); if (n < 0) err = got_error_from_errno("read"); - else if (n != idlen) { + else if (n != digest_string_len) { err = got_error(GOT_ERR_BAD_PACKIDX); goto done; } } if (verify) { - got_hash_update(&ctx, h->trailer.packfile_hash, idlen); + got_hash_update(&ctx, h->trailer.packfile_hash, + digest_string_len); got_hash_final(&ctx, hash); if (got_hash_cmp(ctx.algo, hash, h->trailer.packidx_hash) != 0) err = got_error(GOT_ERR_PACKIDX_CSUM); blob - 42906a3ad5dc8e31e2858ff79937b7a91ecb6ddb blob + 116131bdf6703cf5fe030ee142ac6ffed00267b4 --- lib/privsep.c +++ lib/privsep.c @@ -1456,7 +1456,7 @@ send_tree_entries_batch(struct imsgbuf *ibuf, struct got_parsed_tree_entry *pte = &entries[i]; /* Keep in sync with struct got_imsg_tree_entry definition!
