Some background can be found in this mail thread: *https://firstname.lastname@example.org/msg00802.html <https://email@example.com/msg00802.html>* The summary is that we want to normalize the paths to increase cache hits, and one simple and robust way of doing that is to use realpath. Writing a custom function that both normalizes paths and doesn't expand symlinks might be possible, but note that there are tricky edge cases that need to be handled. > Thank you for considering it. A patch is in the attachment. ccache has a test suite and it fails like this with your patch: Running test suite basedir... FAILED Test suite: basedir Test case: Path normalization Failure reason: Expected "cache hit (direct)" to be 1, actual 0 [From your original mail:] > For directories they do not work on, but are required to build the sources > they work on, they create a symbolic link to a reference area in which > only stuff required for building resides. [...] Now, assume user1 sets > `base_dir` to `/user1` and user2 sets `base_dir` to `/user2`. If I understand your setup correctly, would it be possible to instead put /reference, /user1 and /user2 under a /common directory and then let the users set basedir to /common? -- Joel On 17 September 2017 at 10:43, Andreas Wettstein via ccache < firstname.lastname@example.org> wrote: > > Seems like a pretty niche use case, but if you can come up with a > > patch that doesn't break too much of current behaviour - why not. > > Thank you for considering it.
