feat: git log the history of one file only

[snowyu]

Currently the git.log shows all history of the commits. Miss the commits history of the filepath only.

git log -- [filepath]

[snowyu]

with follow supports now, you should set follow and force both to true.

The another same pr is snowyu:feat/log-async-iterator, It make code more clear to read for using the async iterator. But I have to add the @babel/plugin-proposal-async-generator-functions plugin.

Regarding: src/utils/resolveFileIdInTree.js

This is tricky to do well without having implemented git's actual algorithm for detecting file renames. Comparing just the file oid and grabbing the first one that matches a top-down breadth-first search seems risky. What about using _walk and grabbing all the blob paths that match oid and only following if there is 1 and exactly 1 match? That way we won't accidentally follow the wrong file.

It ends up doing more CPU/IO work to exhaustively determine the file moved rather than was copied, but _walk is also optimized for concurrency so it might even be faster than the current algorithm in some case.

[snowyu]

Aha, I missed a plurality of the same content exists, thank you pointed out.

The _walk is too special(advanced) to walk GitTree. We need a low-level walkTree which walks GitTree only.

[snowyu]

Ok, I've resolved though comparing all the filepaths with last all filepaths of the same content to determine the correct file name.

Hi, I'm a new maintainer and I will be able to merge your PR if you resolve the conflicts in the files.

[snowyu]

Merged.

[jcubic]

Please check the conflict, there was a change:

    if (tips.length === 0) {
      break
    }

was removed.

Also please remove the example git hooks from testing fixtures.

[snowyu]

It has changed to this:

https://github.com/snowyu/isomorphic-git/blob/634e7da134f96edd1e5b1f34c116bd024f4e219f/src/commands/log.js#L161

    // Stop the loop if there are no more commit parents
    if (tips.length === 0) {
      endCommit(commit)
      break
    }

[jcubic]

You added a line to the code that got removed. There are no longer that if (tips.length === 0) { check in the code.

    // Stop the loop if there are no more commit parents
    if (tips.length === 0) {
      endCommit(commit) // this make the conflict because surrounding code got removed
      break
    }

[jcubic]

So please update your fork with the latest version. And check how you can do the same without that line. Right now the code don't use while (true) { and break anymore.

[snowyu]

Oh, I didn't notice that the mian branch has been updated again. done..

[jcubic]

Note that {Boolean=} was correct the option is optional. You should not remove that only added default parameter and name in bracket.

[jcubic]

You've merged origin/main but not updated your fork with upstream/main.

[jcubic]

Sorry I was mistaken your fork was updated. I need to look closer at your code since the logic of that loop was modified recently.
