reduce_heads: fix memory leaks

2017-11-08T02:34:00Z

We currently have seven callers of `reduce_heads(foo)`. Six of them do not use the original list `foo` again, and actually, all six of those end up leaking it. Introduce and use `reduce_heads_replace(&foo)` as a leak-free version of `foo = reduce_heads(foo)` to fix several of these. Fix the remaining leaks using `free_commit_list()`. While we're here, document `reduce_heads()` and mark it as `extern`. Signed-off-by: Martin Ågren Signed-off-by: Junio C Hamano

Merge branch 'po/read-graft-line'

2017-09-06T04:11:25Z

Conversion from uchar[20] to struct object_id continues; this is to ensure that we do not assume sizeof(struct object_id) is the same as the length of SHA-1 hash (or length of longest hash we support). * po/read-graft-line: commit: rewrite read_graft_line commit: allocate array using object_id size commit: replace the raw buffer with strbuf in read_graft_line sha1_file: fix definition of null_sha1

Merge branch 'rs/commit-h-single-parent-cleanup'

2017-08-24T17:20:03Z

Code clean-up. * rs/commit-h-single-parent-cleanup: commit: remove unused inline function single_parent()

commit: remove unused inline function single_parent()

2017-08-19T16:24:05Z

53b2c823f6 (revision walker: mini clean-up) added the function in 2007, but it was never used, so we should be able to get rid of it now. Signed-off-by: Rene Scharfe Signed-off-by: Junio C Hamano

commit: replace the raw buffer with strbuf in read_graft_line

2017-08-18T19:18:10Z

This simplifies function declaration and allows for use of strbuf_rtrim instead of modifying buffer directly. Signed-off-by: Patryk Obara Signed-off-by: Junio C Hamano

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

shallow: convert shallow registration functions to object_id

2017-05-08T06:12:57Z

Convert register_shallow and unregister_shallow to take struct object_id. register_shallow is a caller of lookup_commit, which we will convert later. It doesn't make sense for the registration and unregistration functions to have incompatible interfaces, so convert them both. Signed-off-by: brian m. carlson Signed-off-by: Junio C Hamano

timestamp_t: a new data type for timestamps

2017-04-27T04:07:39Z

Git's source code assumes that unsigned long is at least as precise as time_t. Which is incorrect, and causes a lot of problems, in particular where unsigned long is only 32-bit (notably on Windows, even in 64-bit versions). So let's just use a more appropriate data type instead. In preparation for this, we introduce the new `timestamp_t` data type. By necessity, this is a very, very large patch, as it has to replace all timestamps' data type in one go. As we will use a data type that is not necessarily identical to `time_t`, we need to be very careful to use `time_t` whenever we interact with the system functions, and `timestamp_t` everywhere else.
