Summary: Ref T10547. This has been around for a while but I was never able to reproduce it. I caught a repro case in the cluster recently and I think this is the right fix. We tell Subversion to run `ssh-connect` instead of `ssh` so we can provide options and credentials, by using `SVN_SSH` in the environment. Subversion will sometimes kill the SSH tunnel subprocess aggressively with SIGTERM -- as of writing, you can search for `SIGTERM` in `make_tunnel()` here: http://svn.apache.org/repos/asf/subversion/trunk/subversion/libsvn_ra_svn/client.c By default, when a PHP process gets SIGTERM it just exits immediately, without running destructors or shutdown functions. Since destructors/shutdown functions don't run, `TempFile` doesn't get a chance to remove the file. I don't have a clear picture of //when// Subversion sends SIGTERM to the child process. I can't really get this to trigger locally via `svn`, although I was able to get it to trigger explicitly. So I'm only about 95% sure this fixes it, but it seems likely. Test Plan: Locally, I couldn't get this to reproduce "normally" even knowing the cause (maybe Subversion doesn't do the SIGTERM stuff on OSX?) but I was able to get it to reproduce reliabily by adding `posix_kill(getmypid(), SIGTERM);` to the body of the script. With that added, running the script with `PHABRICATOR_CREDENTIAL=PHID-CDTL-...` in the environment reliably left straggler temporary files. Adding `declare()` and a signal handler fixed this: the script now runs the `TempFile` destructor and longer leaves the stragglers around.
