Git push to drupal.org always returns "Everything up-to-date" This same question was asked many times, but for now I didn't find any help in the responses.

I have a project in a sandbox which I frequently pushed to the DrupalGit repository without any issue during review process.

Then after successfully getting permission, I first wanted to simply promote my sandbox to a full project according to these instructions, but for some reason editing my sandbox page never showed me the "Promote" tab.

So I decided to create a full project from scratch, then I followed its "Version control" tab documentation to create and populate the corresponding repository: compared to the sandbox's one, you can see that it only contains the myModule.info file.
(this file is not the "true" myModule's info file: it was created in the earlier steps prescribed by the above doc). 

Once successfully pushed this and added a "7.x-1.0" tag as also prescribed, I locally copied all my real files from sandbox to full-project directory, git-added them and git-committed them.

Then from now on, any git push origin 7.x-1.0 simply returns "Everything up-to-date", and obviously nothing is updated in the DrupalGit repository.

I looked at many posts and docs, in the Drupal community and elsewhere, tried a lot of more or less serious methods.
I even dropped all files but myModule.info from my local repository: pushing this committed situation also returns "Everything up-to-date", and indeed the same after bringing them again.

I could observed something weird when clicking the myModule.info file to display its contents:


in the sandbox repository it appears formatted with line numbers, as expected, and clicking "plain" displays its raw content
but in the full project repository it displays in hexdump mode, And clicking "plain" causes its download to be proposed!


This clearly means that the file in a somewhat strange state, and midht be significative... but not for me at the moment :-)
This not a real "answer" to the question I asked, but only the method I finally found to get out of my blocking situation.

Since it seemed not possible to make the remote repository to accept push attempts from its associated local repository, I took the problem from the opposite end.

After all it appears as a quite simple solution:


I renamed my local repository, say to myModule.old
I cloned the remote repository with
git clone --branch 7.x-1.x [myName]@git.drupal.org:project/myModule.git,
so getting a new myModule local repository
then I pasted whole contents from myModule.old into myModule, added and committed them
and finally used a simple git push origin (NOTE: without tag mentioned), with success


BTW, it's interesting to notice that trying with the tag mention again returned the "Everything up-to-date" message.
In the other hand, once pushed new contents, the myModule.info file displays normally rather than with the previous weird fashion.

Hope this helps somebody.
