[Zope-dev] December release post-mortem
Now that I've had a week or so to recover from making the Zope 3 releases, I'd like to look at how we did on our first timed releases. Of course, the releases didn't happen in December. In fact, the Zope 2 Windows release still hasn't happened. That we were late isn't a great surprise, given that this was our first timed release. The beginning of the release cycle was delayed because people didn't really realize/remember that we needed to freeze by November 1. The release was delayed past December in large part due to problems found with the Zope 3 Twisted server. In retrospect, I should have accepted these, made ZServer the default and marked the twisted server experimental. Instead, I spent 2 weeks thinking the resolution only needed a few more hours of work. I should have known better. I'm disappointed that the people pushing the Twisted server didn't provide more help during this period, but it was a holiday time and one of the main drivers, Stephan, warned way in advance that we shouldn't be finishing a release during a holiday period. Of course, we should have been finishing the release in early December. In the future, if someone introduces a major change, they *must* be committed to be available to deal with issues that arise during the release cycle. Perhaps we need to pick different release dates to avoid holidays. Stephan has suggested moving the dates up to November/May rather than December/June. And then there are the Windows releases. Making Zope 2 windows releases is very painful and there don't seem to be many people willing to help. We've avoided the pain for Zope 3 by being less ambitious. We let distutils do most of the work. The result is that making a windows release takes minutes and is highly automated, but the experience for the end user is less than ideal, Many would rightfully argue that it is inadequate. What we need is a release process that is as easy as the Zope 3 windows release process and produces a result as usable as the Zope 2 windows release. I'm not sure exactly what the answer is, but I am sure we need to take a fresh approach. Whatever approach we take needs to be highly automated and must not require a lot of specialized Windows expertise. I think that packaging is a significant challenge to our release process. The Zope 2 release was complicated by the use of zpkg. The zpkg system was developed to allow us to decouple the Zope 3 repository and releases. It was too painful to mold the repository to fleeting release decisions. We wanted people to put experimental and add-on applications in the repository so that they would be tested as we rapidly evolved things. While zpkg was crucial for the last 3 releases, I don't think it provides the best long-term approach. Rather than extracting a release from a larger repository tree, I think it would be better, going forward, to assemble a release from smaller individual repository trees or from releases. This is feasible because: - Python is finally growing a packaging system with eggs, - buildbot provides a mechanism for getting things tested without putting everything in a single repository, and - the new test runner's layer makes it feasible to define independent functional tests for packages. We have begun to see Zope 3 decomposed into separate projects knit together via svn:externals. I'd like to see that trend continue and to perhaps switch to making the knitting process use eggs, I'd like to leverage eggs to make the release process much simpler. It should be easy for people to make releases so that there could easily be multiple distributions aimed at different needs and expectations. As part of this decomposition, we need to make zope.app much smaller. Early in Zope 3 development, I proposed a simple rule for organization of the repository: Anything that depended on zope.app went in zope.app. Anything else went in zope. If there was doubt, put it in zope.app. I think that served us well at the time, but I think we've moved beyond that, I'd like to migrate most of zope.app elsewhere. Zope 2.10 should not include zope.app. Note that I'm banking heavily on eggs without personally having worked with them much. I'm very hopeful that we can make them work for us. In the end, I consider the December release to be largely successful, given the challenges. These were some of my reactions to this first attempt at time-based releases. What do other folks think? Given that the Zope Foudation will be formed during this next release cycle, I think this is a good time to take stock and think about how to move forward, Jim -- Jim Fulton mailto:[EMAIL PROTECTED] Python Powered!

Speaking for the Zope 2 release: - the zpkg chances were introduced very late and it was somewhat annoying to deal with this almost untested changes during the betas (not blaming Philipp here, he has done a tremendous lot of work) In addition such major changes should happen on a branch and not on the trunk and such changes should be started early before the next release (not week or two before the first beta).

[Zope-dev] Re: [Zope3-dev] December release post-mortem
Hey, First, I'd like to thank you and everyone involved in the Zope 2 and Zope 3 releases for making this time-based release in what I consider to be a smashing success. Thanks for all the hard work! Things were late a bit, some things are imperfect, but we in the community are already feeling the positive effects of being able to plan for releases. I want Jim to be sure he realizes it's a success from other's perspective as well. Several great features are probably in Zope 2 now in part due to the time-based release system. I want to point out for special attention Florent's great work on making Zope 3 style events work with Zope 2. This is no less than fantastic. This kind of work might've lingered for a long time if release dates were uncertain. Jim Fulton wrote: Now that I've had a week or so to recover from making the Zope 3 releases, I'd like to look at how we did on our first timed releases. Thanks for doing the post-mortem. Very valuable. Of course, the releases didn't happen in December. In fact, the Zope 2 Windows release still hasn't happened. That we were late isn't a great surprise, given that this was our first timed release. The beginning of the release cycle was delayed because people didn't really realize/remember that we needed to freeze by November 1.

Stephan has suggested moving the dates up to November/May rather than December/June. +1 to moving the dates to be further away from holiday seasons. And then there are the Windows releases. Making Zope 2 windows releases is very painful and there don't seem to be many people willing to help. [snip] Getting a dedicated volunteer to work on Windows releases seems to be hard. I've tried with lxml and while several people have successfully compiled it on Windows, and several people volunteered to help with releases, it still hasn't gotten off the ground. I'm glad the decision was made to let Windows not be a release blocker. We're not the only one with this problem. A few months ago I was reading the Apache HTTP server mailing lists and to my surprise found a thread talking about how their process was failing. The Apache HTTP server has a very strict policy concerning changes to the codebase; they have to be vetted by other programmers before they can go in. There were some problems pointed out about this procedure slowing things down, but interestingly enough one of the blockers for making new releases of Apache was the volunteers not knowing how to do a Windows release. :) I think that packaging is a significant challenge to our release process. The Zope 2 release was complicated by the use of zpkg. The zpkg system was developed to allow us to decouple the Zope 3 repository and releases. It was too painful to mold the repository to fleeting release decisions. We wanted people to put experimental and add-on applications in the repository so that they would be tested as we rapidly evolved things. While zpkg was crucial for the last 3 releases, I don't think it provides the best long-term approach. Rather than extracting a release from a larger repository tree, I think it would be better, going forward, to assemble a release from smaller individual repository trees or from releases. I'm glad this is being given a re-think. How do you assemble releases 'from releases'? I'm not sure I understand that. You mean make a Zope 2 release using a Zope 3 release? You know my position concerning the repository and the release; I'd prefer them to be kept as similar as possible to simplify the release process. I hope we can go in that direction. It also makes things more predictable to developers. We noticed that some Zope 3 packages weren't packaged into Zope 2 after the release, even though in a developer's sandbox of Zope 2 they were there. As a side issue: From the perspective of Five, it is beneficial to have as much Zope 3 code included into Zope 2 releases, as that gives us an opportunity to start using this functionality right away, exposing it to Zope 2, without waiting for a new release. [snip] We have begun to see Zope 3 decomposed into separate projects knit together via svn:externals. I'd like to see that trend continue and to perhaps switch to making the knitting process use eggs, I'd like to leverage eggs to make the release process much simpler. It should be easy for people to make releases so that there could easily be multiple distributions aimed at different needs and expectations. I'll repeat here that I think there's much value in trying to keep the mapping of the SVN repository very similar to what is actually released. (If you're interested I can try to explain some of my thinking a bit deeply.) Eggs are a nice distribution mechanism, but

[Zope-dev] Re: [Zope3-dev] December release post-mortem
We should distinguish between authoring the Windows
build-the-installer code, and running that code. Making a Zope 2
Windows release consists of _running_ the build-the-installer code,
and is easy. It's actually easier than building a Zope 3 Windows
release: once the Python tarball, Zope 2 tarball, and pywin32
installer are downloaded, building a Zope 2 release consists of typing
one command in a Cygwin shell:
WinBuilders/buildout zope
That's it.
_Authoring_ the Zope 2 build-the-installer code has been a royal PITA,
but work is needed there only when packaging gimmicks change. Like
moving to zpkgtools, or moving away from them again, or moving to a
different packaging system for one of the components (like Python
moving from a Wise installer to an MSI installer for 2.4, or pywin32
earlier moving from a Wise installer to a distutils installer).
Across the long life of Zope 2.7, those things changed very little,
and as a result very little needed to change in the
build-the-installer code across 2.7's life. 2.7 Windows releases
remained easy to build across that time (granting that Mark Hammond
did the work to adjust to pywin32's packaging changes).
2.8 Windows releases were/are similarly easy to build.
A lot of new work was needed for 2.9, due to Python and zpkgtools
changes. I also took the opportunity to upgrade from InnoSetup 4 to
version 5, which introduced a much easier scheme for managing the
custom dialog screens in the Zope installer.
All of that ended up making the build-the-installer code substantially
simpler, to the point where it now seems kinda goofy to use makefiles
at all in the process. Makefile mazes are inscrutable, and are
particularly ill-suited to the true nature of this task: unpack
various tarballs, and rearrange them like so.
Finishing a Windows release of Zope 2 or Zope 3 takes much longer than
just minutes, unless you skip testing. If you do skip testing, then
it's minutes for both. Testing Zope as a Windows service is harder
for Zope 3, because the Zope 3 installer doesn't (but the Zope 2
installer does) install or start the service, or auto-stop and remove
the service when Zope is uninstalled. BTW, Zope3 _could_ do that too
with a suitable post-install/pre-uninstall script, which is something
InnoSetup automates for Zope2.
It can take a Windows expert some days to author Zope2
build-the-installer changes when packaging fashions change (whether
Zope's or the repackaged components'). InnoSetup is the least of the
problems there, and while MSI is the coming fashion, slinging MSI code
appears to require much more knowledge than slinging InnoSetup
declarations.
The idea that it takes Windows expertise to write an InnoSetup
declaration is wrong: such lines merely say take the files you find
_here_ now, and put them _there_ when the installer runs. For
example, this is the entire Inno code needed to install Zope 2's lib/
directory:
Source:lib\*.*; DestDir: {app}\lib; Flags: ignoreversion recursesubdirs
That kind of stuff is truly trivial. It does take Inno expertise to
create and manage the installer's dialog screens (manage == e.g., if
the user chooses not to have the installer create an instance home,
then the dialog asking for the instance home's directory shouldn't be
shown), but those typically don't change across releases.

Assuming that eggs fullfill their promise, I think I'd rather use eggs than externals. As part of this decomposition, we need to make zope.app much smaller. Early in Zope 3 development, I proposed a simple rule for organization of the repository: Anything that depended on zope.app went in zope.app. Anything else went in zope. If there was doubt, put it in zope.app. I think that served us well at the time, but I think we've moved beyond that, I'd like to migrate most of zope.app elsewhere. Zope 2.10 should not include zope.app. This worries me; Five is currently using massive quantities of code in zope.app, and as expressed above, I value Five having access to potentially all Zope 3 code that's in a Zope 3 release.
