Please do not simply delete and re-add the enlistment. In most cases
this does not have any effect (our system will recognize the URL and
simply re-add the existing broken download), and it will complicate

 I think these are them:

 They're preventing Zope stats on ohloh from getting updated regularly, I

There's a pypy sprint going on in Switzerland next week:

Just wondering if anyone has plans to attend it and push some ztk on

 I see that your implementation uses last-modified + size, which should

 useless.

 Would you prefer a sha1 checksum?

As a default? I'd say last-modified + size is OK.

 On a completely different note, I see that the File object reads the
 whole file into memory.

 And it does that twice for every request that results in a 200 response:
 once to auto-detect the content-type, the second time to return the
 actual data.

Ouch. That sounds pretty bad. I thought it kept the data in-memory
(didn't look close enough at the source).

 Finally, I push my branch up to Launchpad::

Once the branch is submitted to Launchpad, it is also possible to
create a Merge Proposal, which is a step up from a patch. Reviewers
can see a live diff on the Merge Proposal that gets updated every time
you do a new 'push'. Merge Proposals also have their own state.

There's a dashboard for keeping track of pending and approved Merge
Proposals, eg:

  https://launchpad.net/zopetoolkit/+activereviews

(the same exists for users: https://launchpad.net/~sidnei/+activereviews)

If you have bzrtools installed, you can use the 'bzr lp-submit'
command to create a Merge Proposal from the command line, IIRC.

It might seem like extra work at first, but once you get used to using
Merge Proposals to track work that's pending a merge it pays off very
quickly.

snip

 A branch made using 'bzr checkout' is bound to the SVN repository:
 commits are automatically pushed back to the master. When working in
 bzr, I really like the ability to batch up local commits, so I often
 create a local branch of the bound one, hack on it with multiple
 commits, and then push back to the bound branch.

That's how I work too, even with branches stored in bzr, by having a
'trunk' branch that is bound it saves you a few steps when merging
work back into the main tree. For people that prefer to be really
explicit, you can use 'bzr branch svn+ssh://...' instead of 'bzr
checkout' to create an unbound branch by default. You can also use
'bzr bind' and 'bzr unbind' to switch between bound and unbound.

 Wouldn't it be nice if it was possible?

Not sure if it would. What you really want to do is to merge the bzr
branch you got from Launchpad into the 'trunk' you got from
svn.zope.org, which behaves exactly as Tres described on his previous
email. Pushing the branch directly without merging first would
overwrite the contents of the target branch with the contents of the

 Hello,

 For a long time, I've wanted to have a subunit output formatter for
 zope.testing. Subunit is a language-generic streaming protocol for
 test results. Once a test runner can display subunit output, it
 becomes much easier to write tools to process output programmatically.
 We want to use it in the Launchpad project for analyzing test results
 and for distributing our test runs across multiple machines. Other
 projects use it to get Hudson integration, or to glue their
 multi-language test suite into one result. More information on subunit
 can be found at http://launchpad.net/subunit.

 I've written a patch that adds subunit support to zope.testing by
 adding a new formatter object. The patch comes complete with tests and
 a willingness to jump through whatever legal hoops might be required
 to get it to land. The patch is attached, and can also be found as a
 merge proposal on Launchpad at
 https://code.edge.launchpad.net/~jml/zope.testing/subunit-output-formatter/+merge/19825

 I look forward to your replies.

The patch looks great to me, specially the testing coverage and the
fact it is completely optional to use subunit. Big +1 from me.

@Marius: re: run() vs run_internal(), the former would cause a
sys.exit() at some point, so run_internal() was added. I didn't spot
this change, but it looks fine to me.

I volunteer for commiting this patch and making a new major release,
if no one else volunteers.

 I have no idea why; I've asked Sidnei to clarify that particular
 changeset in Chameleon (although I suspect it was just carried over
 as-is from ``zope.pagetemplate``).

As far as I remember, it was just carried over as-is. Some (local)
tests that expected it to be gone were failing with chameleon.

Hi Charlie,

 I only know about it because I keep on it hitting it in Windows installs
 as there isn't a binary of 2.11 with the fix.

You mean the latest binary doesn't have the fix? Or you haven't seen
that a binary was released recently?

 have the windows installer foo to do this by myself and am not willing

 Such a tool would be very very handy.  For example, it could be used

I'm interested in this, but relatively swamped at the moment attending a sprint.

 Thanks for relaying!

 I'm not really sure what he means by edit and then merge without a
 commit inbetween. So I'm assuming there is one.

 Sorry for being overly brief in my description; please find below a
 sample shell script to set up a Subversion repository with a project
 containing a trunk and a branch. To reproduce the problem I'm
 concerned about, do this:

 $ create-repos.sh repos
 $ svn log repos/project/trunk/feature.txt
 
 r9 | wosc | 2009-06-18 17:11:46 +0200 (Thu, 18 Jun 2009) | 1 line

 merged feature1
 
 r8 | wosc | 2009-06-18 17:11:43 +0200 (Thu, 18 Jun 2009) | 1 line

 implemented feature1
 

 As you can see, Subversion reports the history of the file that
 happenened on the branch (in r8).

Can you show us your 'svn --version'? I suspect what you're seeing is
a result of svn 1.5 merge tracking.

 After converting the repository, however...

 $ bzr init-repo repos-bzr
 $ cd repos-bzr
 $ bzr svn-import file://$PWD/../repos
 $ bzr log repos/project/trunk/feature.txt
 
 revno: 3
 svn revno: 9 (on /project/trunk)
 committer: wosc
 timestamp: Thu 2009-06-18 14:11:46 +
 message:
  merged feature1

 ... this history is lost. Not only does it not appear in the log
 output, also when looking at bzr visualize it seems like that branch
 never existed at all in bzr. (I'm new to bzr, am I missing something
 here?)

Like John said, it *should* be possible to bring that information over
if the svn repository is in 1.5 format and contains informations about
merge, but at the moment that (apparently) hasn't been implemented.

 This is a first attempt to build an Mercurial mirror :
 http://hg.zope.mirrors.securactive.org/

 How did you convert the repository?

 I'm asking because I noticed that basically all SVN-DVCS conversion
 tools (hg convert, git-svn, bzr svn-import, svn2bzr, svn-fast-export.py,
 svn-all-fast-export.cpp) do not convert the history properly, more
 precisely, history that happened on branches is lost:

 1. import /trunk/foo.txt
 2. branch /trunk to /branches/mybranch
 3. edit /mybranch/foo.txt
 4. merge /mybranch to /trunk

 If you now ask svn for the history of /trunk/foo.txt (say with 'svn
 log'), you see both steps 3 and 4. After conversion to a DVCS with one
 of the above mentioned tools, you only see step 4, while step 3 never
 happened in the DVCS repository. I think that's unacceptable, most
 importantly because all commit messages that happened on branches are
 lost that way.

 Does somebody here know something about this phenomenon, by any chance?
 Am I missing something?

Here's some context about this from one of the Bazaar developers, John
Arbash Meinel. Hopefully that will solve some of your questions?


In pretty much all dvcs merging a content exactly back to trunk does not
generate a change message when doing bzr log foo.txt.

I'm not really sure what he means by edit and then merge without a
commit inbetween. So I'm assuming there is one.

Now, what really matters is whether or not *Subversion* recorded 4
correctly, such that it can actually see that it was a merge from 3.

My understanding is that before svn 1.5 that isn't possible. So you are
left with trying to infer that sort of thing from the history. Which
would be possible, but probably expensive.

I'm pretty sure SVN represents (4) as not a *merge* but as an indentical
commit.

I don't have a great answer there. Though the fact that Wolfgang says
svn shows both... I suppose because svn log shows everything across
all branches?

 Based on yesterdays discussion, I propose to setup a new mailman

 So anyone can subscribe to Zope 2 ticket changes without having

 Objections?

 The problem is that the visibility of issues in Launchpad is very poor.
 You can't even get notifications of bugs unless you're part of the

 that no-one gets the opportunity to make suggestions or comments. This
 could be improved by getting issue emails sent to this list too, is that
 possible?

Yes, that is possible. But I fear this list might not be the most

I've found the [DM] prefix to be very annoying. You could have used
tags instead.

Regardless of that, thanks for putting those improvements out there.
I've looked at the list and at least a couple of them are very
interesting to me.

 One question is what launchpad project we should use.

 The current launchpad is for Zope 3. The steering group isn't about
 Zope 3. It's about a whole bunch of libraries. Creating a separate
 launchpad project for each library in the framework seems like a bit of
 overkill at this stage, though it would please those people who come at
 us at the perspective from libraries the most.

It smells like 'Zope Framework' (zope-framework) should be a Project
Group then, and there should be a 'Zope Steering Group Project'
(zope-steering-group-project) as part of it, and sibling of Zope 3 and
any other libraries that are part of Zope Framework. For an example of
what this looks like, look at:

I can help setting up this structure, if needed.

[Zope-dev] Differing case for Buildout on Windows

2009-02-05 Thread Sidnei da Silva
I've been constantly bitten by a very annoying bug: depending on how
you call buildout on Windows, a full rebuild might be triggered, if
only the case differs. For example, all the following calls cause
buildout to think settings have changed and that things need to be
rebuilt. Note only the drive letter changes:

  c:\Python24\python.exe bin\buildout-script.py -c
c:\src\some-project\buildout.cfg
  c:\Python24\python.exe bin\buildout-script.py -c
C:\src\some-project\buildout.cfg
  C:\Python24\python.exe bin\buildout-script.py -c
c:\src\some-project\buildout.cfg
  C:\Python24\python.exe bin\buildout-script.py -c
C:\src\some-project\buildout.cfg

Now, I'm wondering what is the best way to fix it. I originally
thought of fixing the data as it comes into buildout, but that would
cause existing buildouts to all possibly trigger a rebuild. I'm now
thinking of fixing the place where buildout detects that the path has
been changed as to normalize the path.

Thoughts?

[Zope-dev] CSRF/XSS: zope.formlib

2009-01-25 Thread Sidnei da Silva
Hello all,

I've been looking at the way CSRF protection is done in Plone
(plone.protect, using a @protect decorator), and also at the XSS
protection added to Zope (@postonly decorator) and was wondering if
something more generic could possibly be done for zope.formlib-based
forms, instead of requiring the use of a decorator.

A quick look though the code, makes seem like an Action could be added
to the Actions object such that the validator would do one (or both)
of those checks, and something similar to the render_submit_button()
which is registered as a @namedtemplate.implementation() would then be
used to render the hidden form field holding the CSRF token for that
specific action.

Does that sound like a reasonable implementation, or is it abusing the
framework?

 Any chance you can get these worked out?  I looked at the Products.Five
 tests today, with the following observations:

  - Not as many tests fail if I run '-s Products.Five' as when I run the
   whole set:  in particular, the first two in 'aqlegacy_ftest.txt'
  ('HTTPError', 'falcon.pt' not called) don't occur.

  - The next 'aqlegacy_ftest.txt' failure is because the content provider
   is not being acquisition wrapped.  The remaining failure is likely
   due to the same cause (it is on the following line).

  - All the failing tests in Products.Five come from code which relies
   on zope.testbrowser, via the Products.Five.testbrowser shim.

  - The first failing zope.testbrowser test (README.txt line 1162) seems
   to be due to a change somewhere which contradicts the comment just
   below the example:  Here, the body is left in place because it isn't
   form data.

  - The testing requirements for zope.testbrowser itself are really
   snarled up:  it pulls in basically all of Zope3.

 Note that what it is doing is forcing a response of 'MS-Author-Via', 'DAV')

 what this is supposed to do is force Word to accept webDAV vs. it's only
 silly thing.  good in theory, but i couldn't get it to work

 After revising the file on the zope server, i then tried Word webDAV.  I
 monitored the network traffic to look for the OPTIONS response telling Word
 to use webDAV.  see attached txt file which has tcp stream while i tried to
 save .doc file.Note that, in the above change, the RESPONSE.setHeader
 ('MS-Author-Via', 'DAV') is supposed to be returned by Zope to force Word to
 work with webDAV, but this does not happen.

 This has been driving me crazy and any help would be greatly appreciated.

 Note:  i have attached the zope 'resource.py' as i have modified it based on
 the above link.  plz let me know if you can see what is wrong.


 Thanks,

[Zope-dev] Proposal: Backporting some Python 2.5/2.6 fixes

2008-10-27 Thread Sidnei da Silva
Hi all,

I would like to propose backporting some of the fixes needed for
Python 2.5 and 2.6 all the way down to Zope 2.10. The fixes that would
be backported would only be those that deal with syntax changes (eg:
'with' and 'as' keyword being used as variables, relative imports) and
some C-level changes, to Acquisition and zope.app.container if I
recall. I would *not* backport changes to RestrictedPython because
those are actually features (support for newer versions of Python) as
opposed to the other changes, which are just 'bugfixes' IMHO.

Would anyone be against this?

2008-10-15 Thread Sidnei da Silva
Folks,

I don't want to rain on your parade, but I already did a first pass at
reviewing the changes in Python 2.5 and Python 2.6. There are no
significant changes that I could spot so far. Apparently the major
changes are:

- Ternary 'if'
- Context Managers ('with' keyword)

Both of those are just syntactic sugar for already existing idioms and
they are pretty much covered by already existing transformation of the
ast tree.

Also, the only new bytecode seems to be 'WITH_CLEANUP' which is part
of the handling of the 'with' keyword.

In general, RestrictedPython seems to be well-structured and the tests
are easy to extend and understand for someone that played with ast
(like the folks playing with z3c.pt).

 kept up-to-date with respect to bugfixes. So it seems like a good idea to
 put this clone out of its misery and retire it.

 I ultimately suggest going to absolute imports everywhere (at least as long
 as we have to maintain Python 2.4 compatibility). I realize that
 DocumentTemplate/DocumentTemplate.py creates a problem. So here's what I
 suggest:

  1. Rename DocumentTemplate/DocumentTemplate.py to, say,
 DocumentTemplate/DocTemplate.py (feel free to come up with
 a better name)

  2. Introduce absolute imports to DocumentTemplate.DocTemplate
 everywhere

  3. Ensure backwards compatibility by adding the following lines
 to DocumentTemplate/__init__.py::

import DocumentTemplate.DocTemplate
import sys
sys.modules['DocumentTemplate.DocumentTemplate'] =
 DocumentTemplate.DocTemplate

 I *think* this should work.

[Zope-dev] ZServer/medusa doesn't work with Python 2.6

2008-10-08 Thread Sidnei da Silva
This one is for someone that has some asyncore knowledge: Python 2.6

[Zope-dev] Python 2.6: 'with' in Interfaces

Trying to run some tests with Python 2.6 I stumbled on a problem that
I need help with: an interface that has an attribute named 'with'.

The interface in question is defined in zope.app.component.back35:

Any suggestions on how to fix this one?

 I'd suggest converting it to an absolute import

So I thought at first. Except there is a problem:

Inside 'DocumentTemplate' there's another 'DocumentTemplate' module. So doing:

 'from DocumentTemplate.DT_Util import parse_params'

... tries to import DT_Util from the relative module. Then the fix is to do:

 'from __future__ import absolute_import'

... except that doesn't work on Python 2.4.

So the try: except seems to be the only way around here, unfortunately.

 or whatever the equivalent for Zope 2 is (I'm assuming it's Zope 2,
 since DT_Util is capitalized).

Another option might be to switch this to use zope.documenttemplate. :)

 The problem right now is, that nobody compiles the

 What do you think, can you do that important part?

Yes, I do compile the binary eggs. And yes, you can expect me to keep

After install, we run bootstrap and buildout with this config file.
All eggs will be in buildout-cache at that point:

Another option would be to use some sort of 'Inno Unpacker', which I

Yet another option would be to just tar up the results of running
'setup.py build-ext -i' on a extracted tarball and put it in some

Re: [Zope-dev] Why I dislike narrative doctests

2008-04-23 Thread Sidnei da Silva
Can't you start a plain-old unittests module and stick your test in
there? Is there any rule that says you cannot create a plain-old test
module if the project you are fixing the bug in uses doctests?

On Wed, Apr 23, 2008 at 5:19 PM, Marius Gedminas [EMAIL PROTECTED] wrote:
 Suppose I find a bug (say, zope.testing.testrunner.StartUpFailure
  objects make unittest.TextTestRunner cry).  Being a good developer I
  want to start the bug fix with a unit test.

  Now if zope.testing used old-style isolated unit tests, I could open the
  tests.py (or tests/test_testrunner.py) in a text editor and start
  writing:

 class OptionsStub(object):
 post_mortem = False

 def doctest_StartUpFailure():
 Test that StartUpFailure is a proper unittest.TestCase

 StartUpFailure is a TestCase-lookalike that is inserted into the
 test suite to indicate that a failed import of a test module
 won't be unnoticed.

  from zope.testing.testrunner import StartUpFailure
  options = OptionsStub()
  module_name = 'test_me'
  exc_info = (ImportError, ImportError('zonkulator'), None)
  test = StartUpFailure(options, module_name, exc_info)
  unittest.TextTestRunner(verbosity=2).run(test)

 This is a regression test for http://launchpad.net/bugs/221151
 

  There, I'm almost done.  Now I can fix the bug and paste the correct
  output into the doctest.

  But zope.testing uses narrative doctests instead of isolated unit tests.
  There are 22 plain-text files that together comprise over 4500 lines of
  text.  Now instead of mechanically opening the appropriate test module
  and grepping for the class/function name I have to figure out which of
  the txt files is the appropriate place for the new test.  After that I
  have to figure out how to insert it into the narrative seamlessly.  Or
  decide to create a new file---but a hundred of .txt files each 20-lines
  long is not a good idea, in my opinion.

  Suddenly I almost don't want to fix the bug any more.

  While I was writing this, I suddenly realised that almost all
  zope.testing's txt files are actually functional tests.  There are
  nearly no unit tests there.  Perhaps that's what causing me pain.

  I still maintain that:

   * adding a new unit test should be a trivial task

   * extending a narrative doctest is not a trivial task

   * the only way to solve this conflict is to explicitly separate unit
 tests (test_*.py) from doctest-enhanced API documentation (*.txt).

Re: [Zope-dev] Re: Zope on Python 2.5?

2007-11-01 Thread Sidnei da Silva
I would like to point out that on this thread people are getting too
tied up with restrictions about *installing* stuff on the system
Python and forgetting that for example, buildout will not install
stuff on the system Python, but people might want to run a Zope (2)
buildout on Python 2.5 just because it's the Python they have
installed.

Now, putting Limi's proven incapability to start a discussion without
causing major commotion from our fellow developers, let's rephrase the
question:

Will Zope 2 be supported on Python 2.5, regardless of whether it's a
system-installed Python or not? I think we are closely approaching the
EOL for Python 2.4. Supposedly when Python 2.6 comes out next year
Python 2.4 will be officially discouraged and will not receive any
more fixes other than security fixes.

I believe this is a critical issue and the interested parts need to
work together on it. Maybe the Plone Foundation and the Zope
Foundation can work together and setup a bounty to fund some developer
to do this work?

Ouch. I guess we should skip 2.5 and target 2.6 then to save some time :)

Erm, can you be more specific? The only two options in zc.recipe.egg

[Zope-dev] Re: Mixing recipes (zc.recipe.cmmi reuse)

2007-09-24 Thread Sidnei da Silva
On 9/24/07, Jim Fulton [EMAIL PROTECTED] wrote:
  Or would it require the recipe
  writer to explicitly 'subclass' (?) cmmi to get patch functionality?

 I prefer composition. A number of recipes reuse the egg recipe
 through composition.

 Generally, an egg will need to explicitly provide a Python API for
 other eggs. See, for example, http://pypi.python.org/pypi/
 zc.recipe.egg/1.0.0b6#egg-recipe-api-for-other-recipes

Gotcha, that makes sense.

  Or even, would a 'post-fetch'/'pre-build' generalization be desired,
  'patch' being one such application?

 I have no idea what that is. :)

My intent is:

Given any recipe, no matter where data is coming from (be it an egg
in PyPI, a Subversion checkout or a tarball), I would like to be able
to perform an operation in the 'local copy' of the data, without
depending on the person that wrote the recipe to have allowed me to do
so

An example being, after a recipe that does a Subversion checkout runs,
my custom operation kicks in and applies a patch to the local copy
before the buildout processing continues.

I believe that this might be doable today by writing custom
configuration, but maybe it's such a common case that could be
simplified.

Maybe something along the lines of (note: this is all pseudo-config):


[Step1]
recipe = some.recipe.checkout
url = svn://url-to-repo/package

[Step2]
recipe = zc.recipe.cmmi
source = {Step1:location}
patch = /path/to/my/patch

[zope2]
products = {Step2:location}


I believe that something like this might already work today, if not it
might be easy to make it work that way. But what I'm after is to avoid
Step2 above by listing the patch to be applied in Step1 even if
'some.recipe.checkout' does not support the 'patch' option directly.

All in all, if you tell me that the hypotetical Step2 above really
can't be avoided and that the best option is to make
'some.recipe.checkout' and any other recipes out support the 'patch'
option directly, I would be fine with that too.

Does it make more sense now?

[Zope-dev] Mixing recipes (zc.recipe.cmmi reuse)

2007-09-18 Thread Sidnei da Silva
Hi there,

Not sure this is the right list, but let's give it a try.

I would like to use the 'patches' functionality from zc.recipe.cmmi
together with other recipes. I believe this is useful functionality
and is interesting to all sorts of recipes, not only to cmmi-based
ones.

So the question is, does the zc.buildout architecture support reusing
options from a recipe on other recipes? Or would it require the recipe
writer to explicitly 'subclass' (?) cmmi to get patch functionality?
Or even, would a 'post-fetch'/'pre-build' generalization be desired,
'patch' being one such application?

Re: Fwd: [Zope-dev] Options replacing DateTime with datetime!?

 Hey Lennart,

  1. Giving the timezone string 'GMT+3' meant that you got the timezone
  GMT-3 back. This was done intentionally and I had some discussion with
  Gustavo about that.

 True.. after these discussions I'm sure that the current implementation
 isn't ideal.  I'll try to fix that in the next dateutil release.


  2. Timezones in the form of EST5EDT or US/Eastern doesn't work.
 
  Both these can be avoided by keeping the old time and timezone
  interpretation around.

 I'm not aware about that.  In fact, I'm curious about what the problem
 is.  EST5EDT may be seen in the test suite several times, using different
 sources of information even.

tz.gettz(EST5EDT)
   tzfile('/usr/share/zoneinfo/EST5EDT')

tz.tzstr(EST5EDT)
   tzstr('EST5EDT')


  The third one is the the modules concept of local timezone is set when
  the module is imported, and there was no way to change it afterwards,

 dateutil can get timezones from several different sources and formats.
 tzlocal is based on what libc exposes, and I don't advice it to be used
 if any better source of information is available.  If the fact that
 some of its data is initialized as module import time is bothering you,
 I can definitely change it, but please keep in mind that there are other
 gotchas (variables in the time module won't change unless you call tzset,
 for instance)

 I recomment using tz.gettz() instead, which doesn't suffer from any of
 the problems you described, and provides much better information
 about the local timezone.


  in effect making any testing impossible, as any tests in converting
  timezones will only work in the timezone of the one who wrote the
  tests. That's a huge problem when you need to test that timezones work
  properly, and IMO opinion makes the module pretty much useless for any

 Making testing impossible is a bit overstated, IMO.  I use TDD in a
 daily basis, and testing that environment seems far from challenging.
 Time-related logic is tricky to test sometimes, of course, but saying
 that dateutil is useless because tzlocal is initialized at import time
 is funny, at least.

 Here is a hot-fix for tzlocal, if that's the problem you're blocked on.

 class tzlocal(dateutil.tz.tzlocal):

 @property
 def _std_offset(self):
 return datetime.timedelta(seconds=-time.timezone)

 @property
 def _dst_offset(self):
 if time.daylight:
 return datetime.timedelta(seconds=-time.altzone)
 else:
 return self._std_offset

 dateutil.tz.tzlocal = tzlocal

Yeah, I had that idea as well, and also tried it and also got stuck on
timezones. :-)
I used dateutil, though, and one of the main problems with that is
that it calculates what timezone you are in when you load the module,
which basically makes timezone testing impossible. pytz may be a
better choice.


Uhm, I am not quite sure that is the case. What exactly is the problem? 
Creating a 'datetime' without timezone information? Why the timezone you are

[Zope-dev] Merging #1441 fix to 2.10 branch?

Hi there,

I would like to merge the fix for issue #1441 into the 2.10 branch. It
restores a 'feature' that was removed almost 35 months ago, but the
feature will be disabled by default, so should not affect anything
unless you enable it in zope.conf. I've added good test coverage for
it, and it has been applied to trunk.

Any objections against applying it to the 2.10 branch?

The issue title should say it all, but here it goes:

Zope used to send a MS-Author-Via: DAV header, which in old versions
of Microsoft Office would cause Word to be fired and try to lock the
file and then open it, which if the user was an anonymous user would
prevent the file download.

Recently (Jan 2005 and May 2007) Microsoft fixed this issue by
updating the WebFolders implementation. Also recent versions of
Microsoft Office don't have this issue either.

The patch adds back the MS-Author-Via: DAV header for compatibility
with old versions of WebFolders, but with a toggle on zope.conf,
default to off.

It also adds a Public: ... header, for compatibility with *new*
versions of WebFolders, which now require it, with another separate
toggle in zope.conf, also default to off.

 Hopefully something similar could be done for files being sent *out*

We already have that. The FileStreamIterator allows you to hand out an

Right, I had something else in mind which is serving large data from

is that application threads should be given back to the pool as quickly
as possible.

If 5 seconds are spend in the application thread to untangle mime data
which has nothing application-specific about it and then only 100ms or
so in the application itself, I'd say there is a major overhead problem.


I had came to the same conclusion a couple weeks ago, somehow *wink*.
Maybe we've been influenced by the same person. :)

So if the uploaded file shouldn't be handled by the application
thread, neither by the IO layer, then I guess we need a 'upload
handling thread pool' of some sorts, whose sole purpose is to handle
incoming requests that are large before it gets to the application
thread while still outside the async IO layer.

Hopefully something similar could be done for files being sent *out*
of the application when they don't need any application processing
anymore (ie, Blobs!).

NTFS does support hard links since version 5, which means Windows
2000+. It does not support hard links to directories though, only soft
links (which are called junctions or junction points). The version of
NTFS shipped with Vista supports hard links for directories I believe.

Mutable default values are evil. I would get rid of that.
