Attached patch patch (obsolete) — Splinter Review
There are a whole bunch of no-longer-used printing error codes, and there are a couple of error codes that exist solely to make a distinction between "during print" and "during print preview", which is already information available at the point where we present the error to the user. This patch removes the unused error codes, exposes the remaining codes in Components.results (nothing uses this now but bug 650960 will want it), and improves the language used for these error messages as long as I'm messing with things. I'm splitting this off of bug 650960 primarily because it touches ErrorList.h and therefore I want to get it landed ASAP to minimize the number of world rebuilds I have to sit through. Feel free to reassign review to someone more appropriate.

I want to avoid changing ErrorList.h more than once, so I want to remove this use so that the error code can also be removed. In context failing here is clearly a mistake (it's inconsistent with logic immediately above and below), but for the time being I'd be willing to change it to NS_ERROR_NOT_IMPLEMENTED instead. This is not the only error in this chunk of code, and it's getting rototilled in bug 629500 anyway. > > default: > >- NS_ERROR_TO_LOCALIZED_PRINT_ERROR_MSG(NS_ERROR_FAILURE) > >+ NS_ERROR_TO_LOCALIZED_PRINT_ERROR_MSG(NS_ERROR_FAILURE); ... > I don't understand this all. Why you move default: to such odd place? I frequently find that it makes more sense in context to place the default: label at the top of a switch. In this case, the desired default behavior is to use the error message associated with NS_ERROR_FAILURE. It makes more sense in context to have NS_ERROR_FAILURE at the top of the list along with the other non-NS_ERROR_GFX_* codes. Therefore, the default label moves too. This is also code that I plan to remove Real Soon (in bug 650960) so I don't mind putting it back at the bottom if you insist. Please advise how I should proceed.
Flags: needinfo?(bugs)
NS_ERROR_NOT_IMPLEMENTED sounds ok. But don't understand your explanation why default: is moved to top. That is not common coding style in Gecko.
Flags: needinfo?(bugs)
I always prioritize local contextual readability over general coding-style guidelines. This particular function is more comprehensible with the default: at the top of the switch, so that is where it goes, and I don't care whether or not it's the "common coding style". Anyway, new patch will turn up in a day or so.

Anyhow, fine by me.

Hi, just wanted to point out: you've changed localizable strings without changing their entities. Many locales won't notice that change and catch up with it.
I'm aware. See bug 849633.
Oh, I didn't notice. Sorry for the noise.
