git/tree.c, branch v2.16.2

Merge branch 'ab/free-and-null'

2017-06-24T21:28:41Z

A common pattern to free a piece of memory and assign NULL to the pointer that used to point at it has been replaced with a new FREE_AND_NULL() macro. * ab/free-and-null: *.[ch] refactoring: make use of the FREE_AND_NULL() macro coccinelle: make use of the "expression" FREE_AND_NULL() rule coccinelle: add a rule to make "expression" code use FREE_AND_NULL() coccinelle: make use of the "type" FREE_AND_NULL() rule coccinelle: add a rule to make "type" code use FREE_AND_NULL() git-compat-util: add a FREE_AND_NULL() wrapper around free(ptr); ptr = NULL

coccinelle: make use of the "type" FREE_AND_NULL() rule

2017-06-16T19:44:03Z

Apply the result of the just-added coccinelle rule. This manually excludes a few occurrences, mostly things that resulted in many FREE_AND_NULL() on one line, that'll be manually fixed in a subsequent change. Signed-off-by: Ævar Arnfjörð Bjarmason Signed-off-by: Junio C Hamano

object: convert parse_object* to take struct object_id

2017-05-08T06:12:58Z

Make parse_object, parse_object_or_die, and parse_object_buffer take a pointer to struct object_id. Remove the temporary variables inserted earlier, since they are no longer necessary. Transform all of the callers using the following semantic patch: @@ expression E1; @@ - parse_object(E1.hash) + parse_object(&E1) @@ expression E1; @@ - parse_object(E1->hash) + parse_object(E1) @@ expression E1, E2; @@ - parse_object_or_die(E1.hash, E2) + parse_object_or_die(&E1, E2) @@ expression E1, E2; @@ - parse_object_or_die(E1->hash, E2) + parse_object_or_die(E1, E2) @@ expression E1, E2, E3, E4, E5; @@ - parse_object_buffer(E1.hash, E2, E3, E4, E5) + parse_object_buffer(&E1, E2, E3, E4, E5) @@ expression E1, E2, E3, E4, E5; @@ - parse_object_buffer(E1->hash, E2, E3, E4, E5) + parse_object_buffer(E1, E2, E3, E4, E5) Signed-off-by: brian m. carlson Signed-off-by: Junio C Hamano

tree: convert parse_tree_indirect to struct object_id

2017-05-08T06:12:58Z

Convert parse_tree_indirect to take a pointer to struct object_id. Update all the callers. This transformation was achieved using the following semantic patch and manual updates to the declaration and definition. Update builtin/checkout.c manually as well, since it uses a ternary expression not handled by the semantic patch. @@ expression E1; @@ - parse_tree_indirect(E1.hash) + parse_tree_indirect(&E1) @@ expression E1; @@ - parse_tree_indirect(E1->hash) + parse_tree_indirect(E1) Signed-off-by: brian m. carlson Signed-off-by: Junio C Hamano

Convert lookup_tree to struct object_id

2017-05-08T06:12:57Z

Convert the lookup_tree function to take a pointer to struct object_id.

Convert lookup_commit* to struct object_id

2017-05-08T06:12:57Z

Convert lookup_commit, lookup_commit_or_die, lookup_commit_reference, and lookup_commit_reference_gently to take struct object_id arguments. Introduce a temporary in parse_object buffer in order to convert this function. This is required since in order to convert parse_object and parse_object_buffer, lookup_commit_reference_gently and lookup_commit_or_die would need to be converted. Not introducing a temporary would therefore require that lookup_commit_or_die take a struct object_id *, but lookup_commit would take unsigned char *, leaving a confusing and hard-to-use interface. parse_object_buffer will lose this temporary in a later patch. This commit was created with manual changes to commit.c, commit.h, and object.c, plus the following semantic patch: @@ expression E1, E2; @@ - lookup_commit_reference_gently(E1.hash, E2) + lookup_commit_reference_gently(&E1, E2) @@ expression E1, E2; @@ - lookup_commit_reference_gently(E1->hash, E2) + lookup_commit_reference_gently(E1, E2) @@ expression E1; @@ - lookup_commit_reference(E1.hash) + lookup_commit_reference(&E1) @@ expression E1; @@ - lookup_commit_reference(E1->hash) + lookup_commit_reference(E1) @@ expression E1; @@ - lookup_commit(E1.hash) + lookup_commit(&E1) @@ expression E1; @@ - lookup_commit(E1->hash) + lookup_commit(E1) @@ expression E1, E2; @@ - lookup_commit_or_die(E1.hash, E2) + lookup_commit_or_die(&E1, E2) @@ expression E1, E2; @@ - lookup_commit_or_die(E1->hash, E2) + lookup_commit_or_die(E1, E2) Signed-off-by: brian m. carlson Signed-off-by: Junio C Hamano

use QSORT

2016-09-29T22:42:18Z

Apply the semantic patch contrib/coccinelle/qsort.cocci to the code base, replacing calls of qsort(3) with QSORT. The resulting code is shorter and supports empty arrays with NULL pointers. Signed-off-by: Rene Scharfe Signed-off-by: Junio C Hamano
