Banish MAX_PATH limit

Open rpavlik opened this issue 4 years ago • 3 comments

We can use a bigger number, but many parts of windows use MAX_PATH so it is a bit of an unfortunate de-facto limit in Windows. Another option is to use PathCchCanonicalizeEx and dynamically allocate the buffer to the length needed. What I did was a bit of a lazy but common pattern in Windows programming.

I think PathAllocCanonicalize is ideal, which will allocate the needed space and then we just free the memory after we make a copy.

Looks like the loader uses MAX_PATH in FileSysUtilsGetCurrentPath and FileSysUtilsGetAbsolutePath too, besides this new addition for FileSysUtilsGetCanonicalPath.
