GitRepo.walkFetchHead

Call the callback function for each entry in the FETCH_HEAD file in this repository.

The callback type must be either FetchHeadFunction or FetchHeadDelegate.

This function will return when either all entries are exhausted or when the callback returns ContinueWalk.no.

void walkFetchHead(FetchHeadDelegate callback)
auto walkFetchHead()

Examples

Walk the FETCH_HEAD file with a function.

auto repo = initRepo(_userRepo, OpenBare.yes);
scope(exit) rmdirRecurse(_userRepo);

string[] fetchHeadItems = [
    "23c3c6add8162693f85b3b41c9bf6550a71a57d3		branch 'master' of git://github.com/D-Programming-Language/dmd\n",
    "aaf64112624abab1f6cc8f610223f6e12b525e09		branch 'master' of git://github.com/D-Programming-Language/dmd\n"
];

std.file.write(buildPath(repo.path, "FETCH_HEAD"), fetchHeadItems.join());

static ContinueWalk walkFunc(in char[] refName, in char[] remoteURL, GitOid oid, bool isMerge)
{
    static int count;
    count++;

    assert(count != 2);  // we're stopping after the first iteration

    assert(refName == "refs/heads/master");
    assert(remoteURL == "git://github.com/D-Programming-Language/dmd");
    assert(oid == GitOid("23C3C6ADD8162693F85B3B41C9BF6550A71A57D3"));

    return ContinueWalk.no;
}

repo.walkFetchHead(&walkFunc);

Walk the FETCH_HEAD file with a delegate.

auto repo = initRepo(_userRepo, OpenBare.yes);
scope(exit) rmdirRecurse(_userRepo);

string[] fetchHeadItems = [
    "23c3c6add8162693f85b3b41c9bf6550a71a57d3		branch 'master' of git://github.com/D-Programming-Language/dmd\n",
    "aaf64112624abab1f6cc8f610223f6e12b525e09		branch 'master' of git://github.com/D-Programming-Language/dmd\n"
];

std.file.write(buildPath(repo.path, "FETCH_HEAD"), fetchHeadItems.join());

struct S
{
    size_t count;

    // delegate walker
    ContinueWalk walker(in char[] refName, in char[] remoteURL, GitOid oid, bool isMerge)
    {
        string line = fetchHeadItems[count++];
        string commitHex = line.split[0];

        assert(refName == "refs/heads/master");
        assert(remoteURL == "git://github.com/D-Programming-Language/dmd");
        assert(oid == GitOid(commitHex));

        return ContinueWalk.yes;
    }

    ~this()
    {
        assert(count == 2);  // verify we've walked through all the items
    }
}

S s;
repo.walkFetchHead(&s.walker);
