perkeep/TESTS

Tests needed

-- integration test of reindexing + race detector

-- support for running race detector on all tests. when in race mode, also run
   integration test children in race mode.

-- test that server/perkeepd still builds & starts even when sqlite isn't
   available (TODO: hide it from the test by running make.go in a child
   process with a faked-out PKG_CONFIG environment or something, to make
   cmd/go unable to find it even if it's installed)

-- search & corpus use of EnumeratePermanodesLastModified

-- pkg/client --- test FetchVia against a server returning compressed content.
   (fix in 3fa6d69405f036308931dd36e5070b2b19dbeadf without a new test)

-cmd/pk-put/
	-verify that stat caching works. verify that -filenodes does create the permanode even if the file was already uploaded (and cached) in a previous run.

-- blobserver/{remote,shard} have no tests. should be easier now that
   test.Fetcher is a full blobserver? see encrypt, replica, and cond's
   nascent tests for examples.

-- app engine integration tests (before we make a release, for sure,
   but probably in presubmit)

-- cross-compiling to freebsd and windows etc still works.

-- pkg/auth -- not enough tests. see regression at
   https://camlistore-review.googlesource.com/#/c/556/1

-- blobserver.WaitForBlob, and integration tests for the http handlers
   for long-polling on Enumerate and Stat
