Squid SMP on MacOS

[Amos Jeffries]

I'm trying to get the MacOS builds of Squid going again but having some 
problems with shm_open() in the Rock storage unit-tests.

1) MacOS defines the max name length we can pass to shm_open() at 30 
bytes. "/squid-testRock__testRockSearch" being 35 or so bytes.
  Cutting the definition in testRock.cc down so it becomes 
"/squid-testRock_Search" resolves that, but then we hit (2).

2) With the short string above and the current settings sent to 
shm_open() in src/ipc/mem/Segment.cc line 73 MacOS shm_open() starts 
responding with EINVAL.

  Any ideas?
