[PATCH v2 0/7] remote rename/remove: improve handling of configuration values

[Bert Wesarg]

While fixing that 'git remote rename X Y' does not rename the values for
'branch.*.pushRemote', it opened the possibility to more improvements in
this area:

 - 'remote rename' did not accept single-letter abbreviations for
   'branch.*.rebase' like 'pull --rebase' does

 - minor clean-ups the config callback

 - patch 5 will be replaced by/rebased on Matthew's work in 'config: allow user to
   know scope of config options', once 'config_scope_name' is available

 - gently handling the rename of 'remote.pushDefault'

Changes since v1:
 * avoid mixed declarations and statements
 * 'git remote remove' learned similar treatment

Bert Wesarg (7):
  pull --rebase/remote rename: document and honor single-letter
    abbreviations rebase types
  remote: clean-up by returning early to avoid one indentation
  remote: clean-up config callback
  remote rename/remove: handle branch.<name>.pushRemote config values
  [RFC] config: make `scope_name` global as `config_scope_name`
  config: provide access to the current line number
  remote rename/remove: gently handle remote.pushDefault config

[PATCH v2 1/7] pull --rebase/remote rename: document and honor single-letter abbreviations rebase types

[Bert Wesarg]

When 46af44b07d (pull --rebase=<type>: allow single-letter abbreviations
for the type, 2018-08-04) landed in Git, it had the side effect that
not only 'pull --rebase=<type>' accepted the single-letter abbreviations
but also the 'pull.rebase' and 'branch.<name>.rebase' configurations.

However, 'git remote rename' did not honor these single-letter
abbreviations when reading the 'branch.*.rebase' configurations.

We now document the single-letter abbreviations and both code places
share a common function to parse the values of 'git pull --rebase=*',
'pull.rebase', and 'branches.*.rebase'.

The only functional change is the handling of the `branch_info::rebase`
value. Before it was an unsigned enum, thus the truth value could be
checked with `branch_info::rebase != 0`. But `enum rebase_type` is
signed, thus the truth value must now be checked with
`branch_info::rebase >= REBASE_TRUE`

[PATCH v4 4/7] remote rename/remove: handle branch.<name>.pushRemote config values

[Bert Wesarg]

When renaming or removing a remote with

    git remote rename X Y
    git remote remove X

Git already renames/removes any config values from

    branch.<name>.remote = X

to

    branch.<name>.remote = Y

As branch.<name>.pushRemote also names a remote, it now also renames
or removes these config values from

    branch.<name>.pushRemote = X

to

    branch.<name>.pushRemote = Y

[PATCH 6/7] config: provide access to the current line number

[Bert Wesarg]

Users are nowadays trained to see message from CLI tools in the form

    <file>:<lno>: …

To be able to give such messages when notifying the user about
configurations in any config file, it is currently only possible to get
the file name (if the value originates from a file to begin with) via
`current_config_name()`. Now it is also possible to query the current line
number for the configuration.

[PATCH v2 7/7] remote rename/remove: gently handle remote.pushDefault config

[Bert Wesarg]

When renaming a remote with

    git remote rename X Y
    git remote remove X

Git already renames or removes any branch.<name>.remote and
branch.<name>.pushRemote configurations if their value is X.

However remote.pushDefault needs a more gentle approach, as this may be
set in a non-repo configuration file. In such a case only a warning is
printed, such as:

warning: The global configuration remote.pushDefault in:
	$HOME/.gitconfig:35
now names the non-existent remote origin

It is changed to remote.pushDefault = Y or removed when set in a repo
configuration though.

Matthew, you are in Cc because of your current work 'config: allow user to
know scope of config options'. I think I'm correct to assuming an ordering
of the enum config_scope.

Changes since v1:
 * handle also 'git remote remove'

All steps looked quite sensibly done.

I expect that Matthew's topic would become solid enough after one
more reroll to name the function back to config_scope_name(); after
that, let's drop the step and instead fork this topic off of Matthew's
topic to queue the remaining patches on top.

Thanks.

please ensure that you have v4 of this patch. What you see was a bug in v3.

I was talking about the current state of what was merged into `pu`:
https://github.com/gitgitgadget/git/commit/6f032056fd7534b8efd712994c02531d83ada957
(note the red X indicating the build failure).

If you already fixed this, and Junio merely has to pick it up, all the
better.

Thanks,
Dscho

I can resend the rebased topic at any time. And as I don't see that
you picked up by latest re-roll (cover in
cover.1579857394.git.bert.wesarg@googlemail.com) in into
bw/remote-rename-update-config yet, I think it makes sense to do this
now.

Best,

[PATCH 3/7] remote: clean-up config callback

[Bert Wesarg]

Some minor clean-ups in function `config_read_branches`:

 * remove hardcoded length in `key += 7`
 * call `xmemdupz` only once
 * use a switch to handle the configuration type and add a `BUG()`
