[PATCH v5 00/15] config: make git_config_set die on failure

Fifth version of the config refactorings, version 4 can be found at [1]. Besides fixing up the Signed-off's and a typo in a commit message pointed out by Eric Sunshine the biggest changes relate to install_branch_config.

Junio pointed out that it might not always be the most sensible thing to die when install_branch_config fails. After thinking about it I changed the behavior of the function to print an error and advise message and return an error code. The error code is then only used by the `git branch --set-upstream-to=` command to abort early, as its main intent will usually be to set the tracking information. The other callers (related to git-clone and git-push) simply ignore the returned value while the messages are still printed.

I think it does make sense to not abort clones and pushes when the function fails. Setting the upstream information is only a small part of these commands and especially when cloning a large repository it is harmful to die as this would delete everything that has just been cloned. The user can still fix up the remote tracking branch afterwards.

A lot of call-sites for the existing family of `git_config_set` functions do not check for errors that may occur, e.g. when the configuration file is locked. In many cases we simply want to die when such a situation arises.

Introduce wrappers that will cause the program to die in those cases. These wrappers are temporary only to ease the transition to let `git_config_set` die by default. They will be removed later on when `git_config_set` itself has been replaced by `git_config_set_gently`.

[PATCH v5 02/15] branch: report errors in tracking branch setup

When setting up a new tracking branch fails due to issues with the configuration file we do not report any errors to the user and pretend setting the tracking branch succeeded.

Setting up the tracking branch is handled by the `install_branch_config` function. We do not want to simply die there as the function is not only invoked when explicitly setting upstream information with `git branch --set-upstream-to=`, but also by `git push --set-upstream` and `git clone`. While it is reasonable to die in the explict first case, we would lose information in the latter two cases, so we only print the error message but continue the program as usual.

[PATCH v5 03/15] branch: die on config error when unsetting upstream

When we try to unset upstream configurations we do not check return codes for the `git_config_set` functions. As those may indicate that we were unable to unset the respective configuration we may exit successfully without any error message while in fact the upstream configuration was not unset.

Fix this by dying with an error message when we cannot unset the configuration.

[PATCH v5 05/15] submodule: die on config error when linking modules

When trying to connect a submodule with its corresponding repository in '.git/modules' we try to set the core.worktree setting in the submodule, which may fail due to an error encountered in `git_config_set_in_file`.

The function is used in the git-mv command when trying to move a submodule to another location. We already die when renaming a file fails but do not pay attention to the case where updating the connection between submodule and its repository fails. As this leaves the repository in an inconsistent state, as well, abort the program by dying early and presenting the failure to the user.

[PATCH v5 06/15] submodule--helper: die on config error when cloning module

When setting the 'core.worktree' option for a newly cloned submodule we ignore the return value of `git_config_set_in_file`. As this leaves the submodule in an inconsistent state, we instead want to inform the user that something has gone wrong by printing an error and aborting the program.

[PATCH v5 07/15] remote: die on config error when setting URL

When invoking `git-remote --set-url` we do not check the return value when writing the actual new URL to the configuration file, pretending to the user that the configuration has been set while it was in fact not persisted.

Fix this problem by dying early when setting the config fails.

[PATCH v5 08/15] remote: die on config error when setting/adding branches

When we add or set new branches (e.g. by `git remote add -f` or `git remote set-branches`) we do not check for error codes when writing the branches to the configuration file. When persisting the configuration failed we are left with a remote that has none or not all of the branches that should have been set without notifying the user.

Fix this issue by dying early on configuration error.

[PATCH v5 12/15] sequencer: die on config error when saving replay opts

When we start picking a range of revisions we save the replay options that are required to restore state when interrupting and later continuing picking the revisions. However, we do not check the return values of the `git_config_set` functions, which may lead us to store incomplete information. As this may lead us to fail when trying to continue the sequence the error can be fatal.

Fix this by dying immediately when we are unable to write back any replay option.

When calling `git_config_set` to set 'core.precomposeunicode' we ignore the return value of the function, which may indicate that we were unable to write the value back to disk. As the function is only called by init-db we can and should die when an error occurs.

I haven't been actively following this topic, so I don't know much about it. However, I just noticed that the topic might brake the OS X build?

Thanks for the notice. Seems I've forgotten to switch that back to `git_config_set`. Didn't notice the breakage as the file is not required on my system.

[PATCH v5 14/15] config: rename git_config_set to git_config_set_gently

The desired default behavior for `git_config_set` is to die whenever an error occurs. Dying is the default for a lot of internal functions when failures occur and is in this case the right thing to do for most callers as otherwise we might run into inconsistent repositories without noticing.

As some code may rely on the actual return values for `git_config_set` we still require the ability to invoke these functions without aborting. Rename the existing `git_config_set` functions to `git_config_set_gently` to keep them available for those callers.

[PATCH v5 15/15] config: rename git_config_set_or_die to git_config_set

Rename git_config_set_or_die functions to git_config_set, leading to the new default behavior of dying whenever a configuration error occurs.

By now all callers that shall die on error have been transitioned to the _or_die variants, thus making this patch a simple rename of the functions.

Looks like there's one more use of git_config_set_or_die that needs to be removed.

Do you have enough information at the point this message is emitted to make it even more useful for the user by showing the actual argument to --set-upstream-to= that the user would need to invoke once the issue is resolved?

Actually, yes. The message is invoked by `install_branch_config` which naturally has to know what upstream we want to set to. Will improve the message in the next revision, thanks.
