  o Minor bugfixes (logging):
    - If we encounter a bug when flushing a buffer to a TLS connection,
      only log the bug once per invocation of the Tor process.  Previously we
      would log with every occurrence, which could cause us to run out of
      disk space.  Fixes bug 33093; bugfix on 0.3.2.2-alpha.
Change BUG() messages in buf_flush_to_tls() to IF_BUG_ONCE() We introduced these BUG() checks in b0ddaac07428a06 to prevent a recurrence of bug 23690. But there's a report of the BUG() message getting triggered and filling up the disk. Let's change it to IF_BUG_ONCE(). Fixes bug 33093; bugfix on 0.3.2.2-alpha. 2020-01-29 14:31:22 +01:00			`o Minor bugfixes (logging):`
