This is a resurection of an old patch serie by Diane Gasselin:
http://thread.gmane.org/gmane.comp.version-control.git/149173/focus=149186
In short, when you have several untracked files that conflict with a
merge or checkout, Git currently reports just the first. After this
patch serie, it reports things like:
error: Your local changes to the following files would be overwritten by checkout:
rep/two
rep/one
Please, commit your changes or stash them before you can switch branches.
most of the job is done by "unpack_trees: group error messages by type",
but this needed a bit of preparation to be implementable cleanly.
Compared to previous version, there are many small cleanups, and:
* unpack_trees_options was a struct, it's now an array. This makes the
code much cleaner whenever one tries to do clever things with it.
That's patch "Turn unpack_trees_options.msgs into an array + enum".
* A message was previously a type + an action ("removed" or
"overwritten"). The type now encompasses the action. This duplicates
a few lines in the declaration of the error messages, but again
makes the rest of the code much simpler. That's patch
"merge-recursive: distinguish "removed" and "overwritten" messages"
* The info on whether traverse_trees should stop at the first error
was stored in info->data, with a very fragile cast to
(unpack_trees_options *). I added one more field in the info
structure to get rid of this cast.

Hmm, the only example of the advantage "enum used as array index" offers that I can think of off the top of my head is that you can more easily iterate over it. > This change needs to rename would_lose_untracked -> > would_lose_untracked_file to avoid a clash with the function > would_lose_untracked in merge-recursive.c. Yes, that shows one upside of "field names in a structure" has over "enum used as array index". We get a unique namespace. If you are to change them to enum, I would actually suggest renaming them a bit more to make them stand out. Perhaps spell them all in caps, perhaps have them share the same short prefix (UTEM_ - unpack trees error messages), etc. Having said all that, I am not against the main idea of this patch. ^ permalink raw reply [flat|nested] 16+ messages in thread

The portion of my message you cite give another: the ability to store the index easily in a variable (or to pass it as argument to a function). With a struct, you can easily pass field name to a macro, but not to a function. The other is that you can have multiple arrays indexed over the same enum, which is what we do later: we'll have to manage an array of list of rejected paths, with one list per error kind. (we'll also have to iterate over this second array) The previous version of the patch serie was using both a struct and an enum + array, and I wanted to get rid of that. > If you are to change them to enum, I would actually suggest renaming them > a bit more to make them stand out. Perhaps spell them all in caps, > perhaps have them share the same short prefix (UTEM_ - unpack trees error > messages), etc. I'd say just "ERROR_*" (UTEM seems hard to read, and won't be used often enough for people to remember it), but I'm fine with all caps + prefix, yes.

This patch adapts the porcelain messages for the case of checkout instead. This way, when having a checkout error, "merge" no longer appears in the error message. While we're there, we add an advice in the case of would_lose_untracked_file.

Instead, we consider them as two different cases, with unparameterized string. This will make it easier to make separate lists sorted by error types later.

As each bind_overlap error combines a file and an old file, a list cannot be done, therefore, theses errors are not stored but directly displayed.

This patch adapts the porcelain messages for the case of checkout instead. This way, when having a checkout error, "merge" no longer appears in the error message.

Yeah, this is a drop in the lego ocean that is Git's source code. Don't worry about it, it can be fixed later. You can stop reading at this point. FWIW "lego" is the i18n term used for printf("messages %s assembled like this", "that are"). E.g.: printf(_("It's a nice %s"), is_evening() ? _("evening") : _("day")); Things like that will cause trouble for e.g. French where it's "C'est un soirée formidable." or "C'est un jour formidable." (I hope I got that right). You can move the %s around, but it's still hard to translate stuff like that, especially as translation programs often display strings independently. It's better to have independent strings like _("It's a nice evening") and _("It's a nice day") instead, even if it leads to duplication. I'll be submitting a lot of patches to fix things like this once the i18n series gets merged. Have fun. ^ permalink raw reply [flat|nested] 16+ messages in thread

Instead, we consider them as two different cases, with unparameterized string. This will make it easier to make separate lists sorted by error types later. Only the bind_overlap case still takes two %s parameters, but that's unavoidable.

As each bind_overlap error combines a file and an old file, a list cannot be done, therefore, theses errors are not stored but directly displayed.
