Also fix the test for <img src tal:attributes="src nothing">.

XMLNS attributes) in rendered output, with an option to keep the old
behavior.

HTMLTALParser.py, TALParser.py:
    Mark TAL, METAL and TAL/METAL-related XMLNS attributes in the
    attribute list; the old macroHack marking is subsumed in this.
    The marking is a third value in the list item describing the
    attribute, saying "tal", "metal" or "xmlns".  All TAL and METAL
    attributes are marked; only XMLNS attributes whose namespace URI
    value is the special marker for TAL or METAL are marked.

TALInterpreter.py:
    - Get rid of the non-functional 'html' keyword argument.
    - Add new 'showtal' keyword argument to constructor; this defaults
      to -1, which means that the value should default to 0 if TAL
      expansion is requested (through the 'tal' keyword argument) and
      1 if TAL expansion is not requested.
    - In do_startEndTag(), don't special-case empty HTML tags; this is
      already taken care of by TALGenerator.
    - Implement the showtal behavior: when this flag is false, don't
      output TAL, METAL and XMLNS attributes (that are marked as such
      by the parser).
    - Fix a bug: <img src="foo" tal:attributes="src nothing"> should
      render as <img>, not as <img src>.

TALDefs.py:
    Bumped TAL_VERSION to "1.0.1"

driver.py:
    New command line option -t to show tal in output

Description: We have a large query implemented via a SQL Method. We've
been messing with it to get the most speed out of it, and noticed a
large hit in the __init__() method on the Results class. We found that
with this simple tweak (see included patch) we got around a 180% speed
up. Not a ton, but pretty good for changing 3 lines of code.

(There's really not a good reason for asynchat to be in
Python's standard lib.)

CVS (1.9).

as I hate line-continuation characters.

Remove done item from TO DO list (CDATA content support).

to a directory other than the ZEO package directory.

Add general support for CDATA element content, enabled by default for
<script> and <style> elements since those are the ones I found in HTML 4.01.

Added a test case to make sure <script> and <style> elements are handled
correctly.

set or cleared by specifying any true or false value.

(XXX I wonder if this should be recognized at compile time rather than
at interpretation time; oh well, this works.)

    more strict about matchnig only what's legal.  The expression ends
    up being a bit more complex, and needs additional checks to be
    done on what follows.

HTMLParser.check_for_whole_start_tag():  Helper method that uses
    locatestarttagend, performs the required additional checks, and
    determines whether we've actually found the end of the start tag,
    are at a buffer boundary, or have encountered an syntactical
    error.


HTMLParser.parse_starttag():  Use check_for_whole_start_tag() to see
    if we really have the start tag.

HTMLParseError.__init__():  Simplify assertion.


This should close ZPT(18).

New tests which poke at transactionalUndo()
    checkSimpleTransactionalUndo
    checkTwoObjectUndo
    checkTwoObjectUndoAgain

    checkUndoInVersion

On the Full storage only, of course.

i.e. it undoes by writing new records.  This means undone transactions
can be redone.  It also has lots of other benefits.

- Made ZPT invoke DTML the normal way.

Also fix the error for a duplicate fill-slot (which was erroneously
reported as a duplicate slot *definition*).

Question arises, should we also complain about duplicate define-slot,
or is it okay to use define-slot with the same name more than once?
This would be similar to "#define X(a) (a+a)" in C; it does point out
that define-slot isn't a great name...

care of installing them when necessary (not for Python 2.0)

Now import asyncore and asynchat as top-level modules, rather than
from the medusa package. This makes it easier to use our custum
version for Python 1.5 and to use the standard versions for Python
2.x.

Note that the Python 2.1b1 and 2.1b2 releases had a broken asynchat
that causes these changes to break Zope. The Python cvs and earler and
later versions are OK.

checkCreateNoFile(), checkCreateWithFilename(),
checkCreateWithFileobj(): Make sure these tests close the file object
before they attempt to unlink the underlying file.y

checkCloseNoUnlink(), checkDel(): New tests in the CreateCommitLogTest
class.

CloseCommitLogTest: removed this class; its tests are folded into
CreateCommitLogTest.

(there's no DB object since we're poking at things at a lower level).

tearDown(): Make sure any outstanding transactions are aborted so as
not to retain modified objects connected to closed databases.  Second,
call self._close() to free any resources.

_close(): Close the DB object, which in turn closes the underlying
storage.

_finish(): In delete-a-version clause, use next_dup() instead of
next() to iterate over the currentVersions table with cursor set to
the vid of the version we're deleting.

abortVersion(): When cruising over the currentVersions table (and the
key set to vid of the version we're aborting), use next_dup() instead
of next().  Also, when curvid <> vid, raise StorageSystemError instead
of VersionError.  Same later on when we check curvid <> zero.

commitVersion(): Add sanity checking based on model documentation: if
the source version is the empty string, or src == dest, raise a
VersionCommitError.  Make the same changes we made previously to
abortVersion() to keep track of the oids in a set/dictionary instead
of a list to avoid duplicates.  Other fixes include, writing revid
instead of tid==self._serial to write_moved_object() and adding a
write_discard_version(svid) once the source version's been committed.

commitVersion() now works!

load(): Add another check to avoid finding an object revision in a
committed or aborted version if we can guess that version name.  It
now raises a VersionError if vid==zero and version is true.

Also, although we still raise VersionError later on, elaborate the
actual exception better in the error message.

    checkAbortVersionErrors
    checkModifyAfterAbortVersion
    checkCommitToNonVersion
    checkCommitToOtherVersion
    checkAbortOneVersionCommitTheOther

All are inhibited for Minimal storage.

(a.k.a. pickle pointer) is usually tid but not always!  In fact, it's
specifically not tid when we've aborted a version -- it'll be the
pointer to the pickle of the last non-version revision.  We were
actually setting up lrevid correctly, but writing tid to the metadata
record.  This fix writes lrevid instead.
