Marshalling code still needs to be converted to re

configure for certain kinds of setups.

to override BaseStorage's tpc_vote().  This isn't necessary for any
subsequent Zope distributions, because BaseStorage has grown an
identical tpc_vote.

little more work.  First, we need to delete all the entries for
oid+vid records in the currentVersions table, then if we delete all
thosey vid entries, garbage collect the version->vid and vid->version
tables.

pack(): Fix a slight misunderstanding of the semantics; if an object
isn't pointed to by root object (i.e. the magic \0\0\0\0\0\0\0\0 oid),
then it's current record doesn't keep it alive.

checkCreateWithFilename(), checkCloseDoesUnlink(), checkDel(): Don't
unlink explicitly, but assert that the file is unlinked after close.

BaseSetupTearDown.tearDown(): It's okay if the tear down unlink fails
because the file already doesn't exist.

suite(): Use makeSuite.

should be on close.  By default, we unlink the file unless we were
passed a file-like object, in which case we don't unlink by default
(because the client owns the file).

close(): Only close the file if the file isn't already closed.  Only
unlink if the default unlink flag is true, or we're explicitly told to
unlink via the argument.  This should fix the logfile turd problem.

Usage: requestprofiler.py filename [--sort=spec] [--top=n] [--verbose] [--help]

Provides a profile of the detailed (-M) Zope request log.

Each line in the profile indicates information about a Zope method (URL)
collected via the detailed request log (the -M log).

'filename' is the path to the '-M' log that contains detailed request data.

If a 'sort' value is specified, sort the profile info by the spec. The sort
spec may be any of 'hits', 'hangs', 'max', 'min', 'mean', 'median', or 'total'.
The default is 'total'.  The sort order is decending unless indicated.

  'hits'       -- the number of hits against the method
  'hangs'      -- the number of unfinished requests to the method
  'max'        -- the maximum time in secs taken by a request to this method
  'min'        -- the minimum time in secs taken by a request to this method
  'mean'       -- the mean time in secs taken by a request to this method
  'median'     -- the median time in secs taken by a request to this method
  'total'      -- the total time in secs across all requests to this method
  'url'        -- the URL/method name (ascending)

If the 'top' argument is specified, only report on the top 'n' requests in
the log (as per the sort).  The default is 10.

If the 'verbose' argument is specified, do not trim url to fit into 80 cols."""

table; use a safer way of pulling out the lrevid.

pack(): The previous logic was broken, now we first gather up all the
oids of the objects affected by packable transactions, then we cruise
through the metadata records of each of those in a separate loop.

Watch out for the call to c.set_range() on the txnoids table to raise
a DBNotFoundError.  This just means we're trying to access a time
stamp past the last one in this table, so just use c.last() if that
happens, and pack all transactions.

When cruising through the txnoids table, stop when you see the first
PROTECTED_TRANSACTION.  That means that we've already packed back to
this transaction (Jim, is this right?  Would we ever want to re-pack a
transaction that's already been packed?)

fails this.

_zaprevision(): Fixed some silly typos.

pack(): Adopt from FileStorage, the conversion scheme of time floats
to TimeStamps.  Also use set_range() on the txnoids cursor because
it's not likely that the timestamp (i.e. revid) will actually exist,
and we just want the one just before the specified time.  Use prev()
instead of prev_dup() on the cursor.

object of its choosing, so we can retrieve the output of RESPONSE.write().

out duplicate oids.  If a pickle holds multiple references to an
object, that object's oids will show up multiple times in the returned
list.

implementation of the GCable `interface' for integration with a cyclic
garbage detector.

Many small structured text fixes, typos fixes, and small wording and formatting corrections. Some of these were pointed out by Tom Deprez.

context check if there is no user context for some reason)

err_exit():  Allow the return code to be passed in, with a default of 2
    (the usual Unix return code for command-line errors).

main():  Remove the try/except that caused a second err_exit() call after
    the first call to sys.exit().  The try/except also prevented the
    first sys.exit() from actually doing so (only the second, unintended
    call caused the script to exit).

    When the users *asks* for help (-h), use a return code of 0 since
    there was not an error that triggered the help message.
