git: Rename the Directory Containing a Repository

When we thought about doing this it seemed like it was going to be a big deal but it turned out to be pretty simple. The following steps accomplished what was necessary:

1. Modify gitosis.conf to add the new directory

[group foo]
writable = foo
members = @developers

[group foo_readonly]
readonly = foo
members = @designers @developers

[group bar]
writable = bar
members = @developers

[group bar_readonly]
readonly = bar
members = @designers @developers

2. mv oldDir newDir

On origin, run the bash 'mv' command
mv foo bar

3. Work with new code

On my development machine, run git clone on the new directory and start working with the files. In our case we were using the old directory name for a new project. Running git pull from my development machine created an empty git repository on origin with the old directory name.

Matcher maker Matcher maker .... make me a Matcher

Ran into a problem at work today that we as a pair were close to giving up on before we finally came across the solution. We had an existing test that was ensuring that our mocked method was called with a pointer argument.

Here is that test:

using ::testing::Return;

TEST(MessageDataTests, SendResponseIsCalledWithMap)
{
    CString messageId = "TestMessageId";
    TXMLDataMap* xmlDataMap = new TXMLDataMap();
    (*xmlDataMap)["MsgId"] = messageId;

    MockTranslator *translator = new MockTranslator();
    EXPECT_CALL(*translator, SendResponse(xmlDataMap))
        .WillOnce(Return());
    translator->GetMessageData(xmlDataMap);
}

As you can see, this test is just ensuring that when SendResponse is called, it is called with the pointer xmlDataMap. We needed to add an expectation on part of what xmlDataMap was pointing too. Google Mock can accomplish this with Pointee(m) where m is a Matcher. Our pointer is not a simple type so we had to create our own matcher to check to see if our map contained the item we were adding inside of GetMessageData.

Here is what the final code looked like:

using ::testing::Return;
using ::testing::Pointee;
using ::testing::AllOf;

MATCHER_P(MapContainsValue, valueToCheck, "")
{
    return (arg.find(valueToCheck) != arg.end());
}

TEST(MessageDataTests, MapContainsDataWhenSendResponseIsCalled)
{
    CString messageId = "TestMessageId";
    TXMLDataMap* xmlDataMap = new TXMLDataMap();
    (*xmlDataMap)["MsgId"] = messageId;

    MockTranslator *translator = new MockTranslator();
    EXPECT_CALL(*translator, SendResponse(
        Pointee(AllOf(MapContainsValue("MsgId"),
                      MapContainsValue("Data")))))
        .WillOnce(Return());
    translator->GetMessageData(xmlDataMap);
}
