+% How often buffered (delayed) updates to a tag need to be
+% flushed. Tradeoff: The longer the interval, the more updates are
+% bundled in a single commit. On the other hand, in the worst case

+% crashes before the commit has finished successfully, making requests
+% more unreliable.
+-define(DELAYED_FLUSH_INTERVAL, (1 * ?SECOND)).

+% How long to wait between garbage collection runs.
+-define(GC_INTERVAL, ?DAY).

+% Max duration for a GC run. This should be smaller than

+-define(GC_MAX_DURATION, (3 * ?DAY)).
+
+% How long to wait after startup for cluster to stabilize before
+% starting the first GC run.
+-define(GC_DEFAULT_INITIAL_WAIT, (5 * ?MINUTE)).

+% The longest potential interval between messages in the GC protocol;
+% used to ensure GC makes forward progress. This can be set to the

+% within this time.
+-define(ORPHANED_BLOB_EXPIRES, (5 * ?DAY)).

+% When orphaned tag can be deleted.
+-define(ORPHANED_TAG_EXPIRES, (5 * ?DAY)).
+
+% How long a tag has to stay on the deleted list before
+% we can permanently forget it, after all known instances
+% of the tag object have been removed. This quarantine period
+% ensures that a node that was temporarily unavailable
+% and reactivates can't resurrect deleted tags. You
+% must ensure that all temporarily inactive nodes
+% are reactivated (or cleaned) within the ?DELETED_TAG_EXPIRES
+% time frame.

-is created and supervised by the ssl_broker_sup.
-
-All communication is between a user and a broker. The broker communicates
-with the ssl_server, that sends its commands to the port program and handles
-the port program responses, that are distributed to users through the
-brokers.
-
-There is a distinction between commands and data flow between the ssl_server
-and the port program. Each established connection between the user and the
-outside world consists of a local erlang socket (owned by the broker) that
-is read from and written to by the broker. At the other end of the local
-connection is a local socket in the port program.
-
-The "real" socket that connects to the outside world is in the port program
-(including listen sockets). The main purpose of the port program is to
-shuffle data between local sockets and outside world sockets, and detect and
-propagate read and write errors (including detection of closed sockets) to
-the ssl_server.
-
-There is documentation in the ssl_broker.erl module.
-
-There is also documentation in the esock.c and esock_openssl.c files.
-
-The ssl_pem.erl, ssl_pkix.erl and ssl_base64.erl modules are support
-modules for reading SSL certificates. Modules for parsing certificates
-are generated from ASN.1 modules in the `pkix' directory.
-
-The `examples' directory contains functions for generating certificates.
-Those certificates are used in the test suites.
