Git creates branches based on historical commit

Today, when using Dbus to implement RPC, it is found that the parameters passed and returned by the remote method are not correct, and the previous few days have been tested obviously normal. So it's natural to think back to the historical version and test it again, to confirm that the test environment has changed, or that the code is being modified.

But how to take out the historical version? Not very good for git, a bit of a toss to finally fix.

1. Determine the commit value of the version that needs to be removed:

#git Log

I need the commit value of the historical version for 92483401abdc41bc64bbdde1a63ed7bbee403e19

2. Remove the version and create the branch

#git checkout-b DBUS_WORK_OK 92483401abdc41bc64bbdde1a63ed7bbee403e19

The branch "DBUS_WORK_OK" was created based on commit "92483401abdc41bc64bbdde1a63ed7bbee403e19" and the code for that version was removed.

A little note:

git checkout-b <branch name> <SHA1>


This will checkout a previous commit and open a branch point to it.

If you do not intend to make changes,
Just want to checkout out, Git checkout <SHA1> on the line, with
Detached head feature.

More can see Git's manul:

#git Checkout--help

The sad reminder is that after the test found that the normal work of the Dbus function, incredibly wrong! Looks like it's a little busy.

-----------------------------------

Ps:

After testing, it was found that the order of the parameters in the Dbus function was modified, resulting in a parameter error passed to the remote.

3. Submit your code:

#git commit-a-M "Fix bug:params incorrect in function rpc_execute_context_query (), which'll cause dbus work abnormal"

Note: This is only submitted to branch "DBUS_WORK_OK" and is not merged on the trunk branch (because the current branch is "DBUS_WORK_OK").

4. Merge to Trunk branch "master":

Switch to Trunk branch "master":

#git Checkout Master

(The current branch is "master")

Merge:

#git Merge Dbus_work_ok

5. Delete the unwanted branch "DBUS_WORK_OK":

#git branch-d DBUS_WORK_OK

6. Continue working on the trunk branch "master".
