[mguemmar]

Describe the bug
When you rename field API Name, the field with the new api name is not pulled and the existing field in repo is deleted
To Reproduce
Steps to reproduce the behavior:

• Rename field name , for exemple : from "myField__c" to "MyField__c" in MyCustoObject__c
• After pull : the original field "myField__c" is deleted in repo (the file "myField__c.field-meta.xml" is deleted) and the new field "MyField__c" is not pulled (the file "MyField__c.field-meta.xml" is not created as expected)
• The next push generate this kind of error
  Error force-app/main/default/objects/MyCustoObject__c.object-meta.xml Not in package.xml

Expected behavior

So this is a bug on Salesforce platform side (not the CLI).

When I rename a field, for instance adding a word, I can see in the SourceMember table (used to track what has changed in the org) that 2 lines are there:

• One with the old name, deleted (IsNameObsolete = true)
• One with the new name

However, when the rename is just the same name with different case, I only have one line for the field deletion.

So this one is definitely harder for us to fix.
What we could do is, every time a field is deleted, query the org to describe the fields of the sObject, and if there is a field with the same name, retrieve it.

I'll try to open a case for it too.

There is also this Known Issue but a little bit different, as I am able to see the deleted field:
