Git theme of send-message does not change, despite the -subject option

Question

I am trying to set the theme for the patch, which I send manually, but for some reason he always chooses the theme for fixing the patch instead of the one I put to him.

I run it like

git send-email --compose --subject="blah" file.patch 

and even if I see the "blah" theme in the editor window that opens, after I save it and try to email the patch, the theme sent by mail still matches the fix fix message.

What am I doing wrong?

Answer 1

You are not doing anything wrong: --compose tells git send-email that you want to write a "cover letter" with the subject that you gave with --subject . The actual commit will be sent in response to this “cover letter,” with the first line of the commit message being the subject.

This is the "standard format", which is understood as git am , so that the recipient can apply the patch and get the same result. This means that changing the subject of the patch message will change the commit message : your recipient will receive another commit, which is probably not what you want.

If you really want to send the commit via email using a custom object, you can prepare your patch using git format-patch and then attach it to an email written in your regular MUA. So the receiver can git am insert.
