Directory-related error processing .pm files #32

I'm getting an error (running pollen on OS X Mavericks) that seems to depend on the directory in which I place my pollen project files.

Here is the error text displayed in the console by raco pollen:

render: foo.html.pm
Servlet (@ /foo.html) exception:

Procedure that produced the bug for me:

Create a minimal foo.txt.pm or foo.html.pm file in /tmp/test/
Run raco pollen start in /tmp/test/
Load the ptree page and click on foo.html.

This error does not occur if I follow the identical procedure in ~/tmp/ instead. AFAICT this seems like a problem in how OS X handles references to parent dir references; I'm basing that on this experiment at the shell:

$ ls /tmp/test/../..
etc      tftpboot tmp      var
$ ls /tmp/test/../../..
Applications     Users            etc              sbin
Library          Volumes          home             tmp
Network          bin              mach_kernel      usr
System           cores            net              var
User Information dev              private

The latter directory listing shows the actual contents of /; I'm not sure where it's getting the former listing. So, perhaps this is an OS X (or Racket-on-OS X) bug, but maybe it can be worked around in Racket?

I believe this is a bug that I caused, and that I fixed on Oct 26 ( 1d31988f2b). If you installed Pollen before then, please do raco pkg update --update-deps pollen to get the fix and let me know if the problem persists.

Hm. Nope, I installed Pollen last night, and the pkg update command shows no further updates available.

OK. I will investigate further.

I reproduced the problem. The specific issue is that /tmp in OS X is actually a symlink to /private/tmp. The general issue is that Pollen was not resolving symlinks. I've just pushed a fix. Thanks for the report.

Great! Thanks for the quick reply.
