Leak fixes. * ma/reduce-heads-leakfix: reduce_heads: fix memory leaks builtin/merge-base: free commit lists
2017-11-08reduce_heads: fix memory leaksLibravatar Martin Ågren1-1/+1
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 <martin.agren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2017-05-08Convert lookup_commit* to struct object_idLibravatar brian m. carlson1-2/+2
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 <sandals@crustytoothpaste.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2014-10-15refs.c: change resolve_ref_unsafe reading argument to be a flags fieldLibravatar Ronnie Sahlberg1-1/+1
resolve_ref_unsafe takes a boolean argument for reading (a nonexistent ref resolves successfully for writing but not for reading). Change this to be a flags field instead, and pass the new constant RESOLVE_REF_READING when we want this behaviour. While at it, swap two of the arguments in the function to put output arguments at the end. As a nice side effect, this ensures that we can catch callers that were unaware of the new API so they can be audited. Give the wrapper functions resolve_refdup and read_ref_full the same treatment for consistency.

2014-06-20use skip_prefix to avoid repeating stringsLibravatar Jeff King1-3/+3
It's a common idiom to match a prefix and then skip past it with strlen, like: if (starts_with(foo, "bar")) foo += strlen("bar"); This avoids magic numbers, but means we have to repeat the string (and there is no compiler check that we didn't make a typo in one of the strings). We can use skip_prefix to handle this case without repeating ourselves. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-06-20refactor skip_prefix to return a booleanLibravatar Jeff King1-1/+1
The skip_prefix() function returns a pointer to the content past the prefix, or NULL if the prefix was not found. While this is nice and simple, in practice it makes it hard to use for two reasons: 1. When you want to conditionally skip or keep the string as-is, you have to introduce a temporary variable. For example: tmp = skip_prefix(buf, "foo"); if (tmp) buf = tmp; 2. It is verbose to check the outcome in a conditional, as you need extra parentheses to silence compiler warnings. For example: if ((cp = skip_prefix(buf, "foo")) /* do something with cp */ Both of these make it harder to use for long if-chains, and we tend to use starts_with() instead. However, the first line of "do something" is often to then skip forward in buf past the prefix, either using a magic constant or with an extra strlen(3) (which is generally computed at compile time, but means we are repeating ourselves). This patch refactors skip_prefix() to return a simple boolean, and to provide the pointer value as an out-parameter. If the prefix is not found, the out-parameter is untouched. This lets you write: if (skip_prefix(arg, "foo ", &arg)) do_foo(arg); else if (skip_prefix(arg, "bar ", &arg)) do_bar(arg); Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2014-06-18avoid using skip_prefix as a booleanLibravatar Jeff King1-1/+1
There's no point in using: if (skip_prefix(buf, "foo")) over if (starts_with(buf, "foo")) as the point of skip_prefix is to return a pointer to the data after the prefix. Using starts_with is more readable, and will make refactoring skip_prefix easier. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-06-13commit: record buffer length in cacheLibravatar Jeff King1-1/+1
Most callsites which use the commit buffer try to use the cached version attached to the commit, rather than re-reading from disk. Unfortunately, that interface provides only a pointer to the NUL-terminated buffer, with no indication of the original length. For the most part, this doesn't matter. People do not put NULs in their commit messages, and the log code is happy to treat it all as a NUL-terminated string. However, some code paths do care. For example, when checking signatures, we want to be very careful that we verify all the bytes to avoid malicious trickery. This patch just adds an optional "size" out-pointer to get_commit_buffer and friends. The existing callers all pass NULL (there did not seem to be any obvious sites where we could avoid an immediate strlen() call, though perhaps with some further refactoring we could).

Each of these sites assumes that commit->buffer is valid. Since they would segfault if this was not the case, they are likely to be correct in practice.
