Normally we'd do the cd inside a subshell, but that's complicated by the wrapper (we wouldn't want to increment the test counter just inside the subshell, for instance). Adding "cd .." is the smallest thing we could do to fix that. But I think the more robust solution is to actually teach the check_* helper about doing the "cd" inside the test_expect block.

Yea, I tried cd inside the subshell and it didn't work, so I did this as the quicker solution. I think the best method would be to update the check_* helper functions to take a dir parameter, and use that to do git -C "dir" when calling the diff commands.

I am not sure what you mean by "pulled out from the others". I did not intend to keep these 3 additional patches permanently; rather, I did them to help Christian's rerolling the series, and I do not think this one should be separate from other ones that use the _default() variant when that happens. ^ permalink raw reply [flat|nested] 15+ messages in thread

I had thought you meant these to be applied on top. Ah, I do not particularly mind doing things incrementally, either. If this goes on top as a standalone patch, then the reason why it is separate from the other users of _default() is not because the way it uses the null return is special, but because it was written by a different author, I would think. The reason why _default() variant exists is because its callers want to react differently to "--foo" from the way they react to "--foo=" (with an empty string as its value), and from that point of view, this caller is not all that different from other ones, like the one that parses --color-words Christian wrote in his initial round. ^ permalink raw reply [flat|nested] 15+ messages in thread

Mostly I was just concerned that we missed a somewhat subtle bug in the first conversion, and I think it's worth calling out in the commit message why that callsite must be converted in a particular way. Whether that happens in a separate commit or squashed, I don't care too much. But I dunno.

Same for the other tests. If you quote it, -C '$in_there', then it will work regardless of if in_there is set or not, (-C with an empty string doesn't cd anywhere). I think this is generally preferable for tests given it helps avoid unnecessary subshells when testing on Windows..? > test_cmp expected actual > " > } > > for type in diff numstat stat raw > do > + in_there= > check_$type file2 --relative=subdir/ > check_$type file2 --relative=subdir > + in_there=subdir > + check_$type file2 --relative > + in_there= > check_$type dir/file2 --relative=sub > done > This isn't quite what I had in mind for the directory parameter.
