      Improve thread-death error reporting in tests. · adb8ff42
      Tim Peters authored
      Reworked the way some of the ZEO tests use threads, so that unittest is
      more likely to notice the real cause of a failure (which usually occurs in
      a thread), and less likely to latch on to spurious problems resulting from
      the real failure.
      
      Detail:  The TestThread class got the (unittest) test case as an argument,
      and remembered it.  If the run() method saw the thread die with an
      exception, it called testcase.fail() with the formatted exception.  But
      this can't work as apparently intended:  unittest's fail() raises an
      AssertionError then, and the piece of unittest running the test expects
      to catch that exception and append the message to the result object's
      list of failures.  But the piece of unittest running the test isn't on
      *this* thread's call stack!  It's on the main thread's call stack.
      So unittest simply raised an exception that wasn't noticed by anything,
      and the thread died then, leaving a traceback somewhere in the middle
      of the output.  unittest didn't know anything about that, and sometimes
      thought the test passed despite the thread failure.
      
      Alas, when a thread dies like this it's also got a decent chance of
      leaving things in a state where the test's final checking code can't
      succeed, but the checking code doesn't know the thread died either,
      and spurious unittest failures and errors could get reported then.
      
      Reworked things so that only the main thread ever tries to tell
      unittest that a test failed.  A TestThread remembers an exception-
      death now, but doesn't report it until the main thread tries to join
      it.  This way unittest knows the test failed; records and reports
      the true cause of failure; and, because tests generally join all their
      threads before doing their final checking, unittest stops the test
      before final checking if a thread death occurred, and so there's
      less chance of seeing reports of spurious errors and failures.

      repozo improvement suggested by Toby Dickenson.
      
      Write backups to a temp file first; flush and fsync when done;
      only then rename; in case of a crash, no relevant damaged file
      will be left behind then.  And on Windows, Python's os.fsync()
      is necessary to convince the OS to write anything to disk.

      Forward port from Zope 2.7 branch, by way of the 3.3 branch. · 7c49891c
      Tim Peters authored
      Repaired a bug wherein spurious error msgs could be produced after
      reporting a problem with an unloadable object (discovered by eyeball,
      while staring at the code to figure out what it actually does).
      
      Vastly expanded the module docstring, with a slimmed-down version of
      the new fsrefs docs on the ZODB Wiki.

      Zope3-dev Collector #139: Memory leak involving buckets and connections
      
      Connection objects were typically immortal because the threaded
      transaction manager kept them in ever-growing lists.  Reworked the
      transaction manager internals to use a simple implementation of weak sets
      instead.  This plugs all leaks in the test program attached to the
      collector report (which was leaking about 100KB/sec on my box).

      Collector #1397: testTimeStamp fails on FreeBSD · a3252542
      Tim Peters authored
      Forward-porting from Zope 2.7.
      Merged from 3.3 branch, revision 26085.
      
      The checkFullTimeStamp() test was sensitive to unique mktime() behavior
      on FreeBSD.  See:
      
      http://lists.freebsd.org/pipermail/freebsd-standards/2003-November/000268.html 
      
      The purpose of this test is to exercise ZODB's TimeStamp object, so got
      rid of dependence on platform mktime() and time.timezone quirks --
      TimeStamp works in GMT, so how mktime() treats tm_isdst should be
      irrelevant in all TimeStamp tests.
      
      Also added a comment about the highly non-obvious numeric characteristics
      of TimeStamp's treatment of seconds (round-tripping is surprisingly
      inaccurate, but for a real reason).

      are in now (partly ZODB 3, partly ZODB 4, partly transitional).
      More is needed.
      Added new collaborations.txt, which spells out some dynamics
      of the system in a compact way.  This is in a format Jim used
      for Zope 3, essentially a flat-text and less-formal representation
      of UML sequence diagrams.

      Collector 1327:  FileStorage init confused by time travel
      
      If the system clock moved back in time more than 30 days between
      a FileStorage close and (re)open, new txn ids could be smaller
      than txn ids already in the database.  Plugged that hole.
