Add new post check for share folder

[Jack·Boos·Yu (JackBoosY)]

Check for non-lowercase share folder.

Robert Schumacher (@ras0219-msft) For regression, should I split the message to fix it?

[Billy O'Neal (BillyONeal)]

I fixed the build failures and I think the change is overall good. Because it adds a new post-build lint we need to pre-run it on the catalog to double check that the world won't break when deployed. Robert Schumacher (@ras0219-msft) Can you confirm you're OK with this now and I can kick that off?

The error was complaining that the localized message ended with \n, thus being likely to create a bug that was present here where it was passed to println doubling the terminal \ns. This check was added in #553

LGTM. Billy O'Neal (@BillyONeal) if you could kick off the test that would be great!

Well, you can just use the file lists from CI... I find

• more than 7000 installed files matching :/share/[A-Z]
• more then 600 CMake configs, by :/share/[A-Z].+/.*onfig.cmake
• more then 60 port dirs, by :/share/[A-Z].+/vcpkg_abi

Why folders in the share folder should be always lowercase?

Good point!

Why folders in the share folder should be always lowercase?

The name vcpkg creates is always, for example, share/${PORT}/vcpkg_abi_info.txt, and ${PORT} is always lowercase. When there are capital ones, it means that users will get different behavior on case sensitive vs. case insensitive file systems, which has been the source of a lot of broken behavior. (like 'works on linux but not windows because the directory names differed only in case')

Example we want the new check to block microsoft/vcpkg#26284 (comment)

Port ogre installs resources to share/OGRE. To be patched?

This mirrors the headers in include/OGRE and the plugins in lib/OGRE.

That's a great point. We do need a policy setting to control the check. Then, we should evaluate whether ogre should disable the policy or whether patching is appropriate. I don't think that matching lib/OGRE/ or include/OGRE/ is by itself sufficient, but if there is an expectation of hardcoded paths containing share/OGRE/ then we may need to simply accept the differences per host platform.

Jack·Boos·Yu (@JackBoosY) Once again, thank you for all your hard work on vcpkg! Would you like to continue this PR or should we take ownership and bring it to completion?

[Jack·Boos·Yu (JackBoosY)]

Robert Schumacher (@ras0219-msft) I will continue this PR.

[Jack·Boos·Yu (JackBoosY)]

Looks good now.

[Kai Pastor (dg0yt)]

It still needs a policy to disable it, and changes to app. 60 ports.

[Jack·Boos·Yu (JackBoosY)]

Robert Schumacher (@ras0219-msft) Billy O'Neal (@BillyONeal) Any feedback?

[Kai Pastor (dg0yt)]

The feedback is only four days old (#675 (comment))

We do need a policy setting to control the check.

Ah I'm blind...

[Jack·Boos·Yu (JackBoosY)]

So what about the 60+ ports / port OGRE?

[Kai Pastor (dg0yt)]

FTR at least to open PRs add new ports with mixed case directories via vpckg_cmake_config_fixup(PACKAGE_NAME <Mixed>). Maybe it would be a good idea to start with improving this function: Convert input PACKAGE_NAME to lower case directory name where feasible.

Will do that after microsoft/vcpkg#29880 microsoft/vcpkg#29882 microsoft/vcpkg#29883 microsoft/vcpkg#29884 and microsoft/vcpkg#29918 are merged.

[Jack·Boos·Yu (JackBoosY)]

Depends on microsoft/vcpkg#31053

[Billy O'Neal (BillyONeal)]

This is a check we wanted but it doesn't seem that we'll be able to given the backcompat problems reported above :(
