Re: [Python-Dev] MSI: Remove dependency from win32com.client module (issue4080047)
It is a surprise to find builtin msilib. Why isn't it used? Originally, because Python needs to be packaged with an older release (in particular one that isn't itself maintained anymore). Today, the problem is that the msilib package doesn't support merge modules (and if such support was added, we would have to wait until the version containing it isn't maintained anymore).

That doesn't answer the question why Python could not be packaged with a newer release of 'msilib' at that time? Today, the problem is that the msilib package doesn't support merge modules (and if such support was added, we would have to wait until the version containing it isn't maintained anymore). I don't understand the phrase in (). What for do we need to wait after adding support for merge modules to builtin msilib? I imagine we've added support for merge modules to msilib, and then waiting until new msilib version with merge support isn't maintained anymore. And only then we can use it to create installer. Sounds like a nonsense. Anyways, is it possible to reuse builtin msilib to the max and add required 'merge modules' functionality inside msi.py or extension module? I don't consider the dependency on win32com a serious issue at all; it's just a mild annoyance (much less than reliance on ctypes would be, or hard-coding of symbolic constants). There is nothing wrong with hardcoded symbolic constants - Microsoft specifically provides values for them in their MSDN materials to be used with scripting languages which doesn't have include files. They just need to be validated one time, and won't change in future. Why don't you like ctypes solution? I find it strange that Python build process avoids using its own modules. -- anatoly t. ___ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com

[Python-Dev] xmlrpclib and communication verbosity
In an attempt to record the xml exchange in an xmlrpclib.ServerProxy connection, I set its verbose flag to 1. This is the whole premise, and the rest of this message contains a bug report, and general complaints about the API. ServerProxy, or to be a bit more specific, the Transport class (which does all the actual printing), provides very little control over where the output goes. By very little, I mean it only outputs to stdout, which is limiting in a server environment where many a prints occur. That, however, turned out to be the least of my worries: xmlrpclib depends on httplib.HTTP to print the outgoing data, but prints its own incoming data, and they tend to collide, in what I permit myself to call a race condition, though it's mostly just simple lack of management of a shared resource (stdout). The resulting output is mostly well-formed, with the occasional nonsense produced by an interjection of one string to the middle of the other. Also, there's the nasty business of Transport.request accepting a 'verbose' param, and then setting it as an instance attribute and using *that*, for no apparent reason except to cause yet another potential race condition. I suggest that httplib.HTTP's verbosity will be controlled by a separate flag, if controlled at all. The outgoing communication can easily be printed by transport, allowing for better control of synchrony. Also, ServerProxy should accept an optional output file (=a class with write,writelines methods), which will be the target of all prints. Would Python be interested in such a patch?

[Python-Dev] alternate fix for urllib2 bug #8797
Hello all, This is my first stab at contributing to this list. I'm writing to lobby for bug #8797's fix to be removed and for my fix to put in in its place. I'm probably doing this wrong, so please bear with me. I will embrace whatever scathing criticism I get. The ticket covers all the details (http://bugs.python.org/issue8797#) but I'll try to summarize here: In 2.6.5, urllib2 had a small regression that caused HTTP 401 errors to trigger an infinite recursion when the request handler had HTTP Auth credentials that the server was rejecting. Previously, urllib2 avoided this loop by checking the previous request's headers to see if it had already tried the credentials it was about to try. If it had, it would re-raise the exception instead of trying again. The current fix adds a max retries concept to urllib2's handling of HTTP 401 errors so that the code will only retry a certain number of times. To me, the original logic of only trying once for each set of credentials was sound, and it looks like the only reason this stopped working was that in 2.6.5 the auth header wasn't being stored in the same place as the code was expecting to find it. I think it makes sense to revisit this issue and swap out the existing fix for my fix because it's tidier and doesn't introduce this new max retries functionality. Please let me know what you think.

If you want to know when something will be fixed, a lot of people will say something like I won't be able to get to this next week, unless you have a patch of your own. I don't see anything wrong with that. In fact, it's pretty common in open source. This person will look into devguide how to send a patch. There will be instructions to download Visual Studio, clone repository, compile, etc. I doubt this person will have time to do this, but next time the person will think twice before reporting.

The visual studio regularly contributes to the wix toolset. They and the .net framework team contributed a lot of the wix bootstrapper (burn) foundational code. I wouldn't call it a platform standard tool. It's becoming that as more and more projects are adopting it. It was considered to be shipped w/ VS 2010 but didn't make it due to management/time issues. The Installer COM object is the platform standard mechanism, and that's what msilib uses. Why maintain a lib when there's (better), free alternatives out there that are maintained by Microsoft itself? (okay, a group at Microsoft that works on their free time, but has significant contributions by many teams at Microsoft -- thus they have a vested interested in its success). I really see no need to move away from that - it can create arbitrary MSI files. Can it create merge modules? Transform files (e.g. localization)? Bootstrappers? There's a lot more to ms installers than the msi itself. Wouldn't it be easier to maintain an XML file than an entire lib dedicated to something that someone else has already solved? ___ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com

Re: [Python-Dev] Python merge module
Using msilib is easier than using Wix. It's also more flexible. IMO, no. It's simply not. All you have to know is how the MSI schema works. Same with WiX. It could easily be extended to do so, in a straight-forward manner. Other packaging apps already have it - no work needed. (actually, there is no need to create the other two types of files, either, as it stands). Sure there is. Transform files + bootstrappers give you localizable installs in one flat file. Definitely not. Python is easier than XML. I disagree. If you think otherwise, feel free to provide a proof in the form of a Wix installation generator for Python. If you think otherwise, why don't you provide proof and get the WiX guys to switch to Python and use your msilib package? The point is that your argument is nonsensical. I'm really not trying to start a flame war here (my original post only asked if there was thought towards migrating away from msilib). There's legitimate need/desire for a merge module to make it easier to package a specific Python version. I can (and am) including it in the bootstrapper, but it would make things much cleaner to simply have a merge module available. If the answer's no and we don't ever intend to, then that's perfectly fine. (c: I really don't care to argue the merits or virtues of WiX vs. msilib and I apologize if I came across as doing that -- I simply was interested to know if there's any serious thought in the matter and it turns out that people are perfectly happy w/ msilib. ___ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com

I'm not familiar w/ shared location merge modules vs. private location merge modules. Are you referring to the possibility of having multiple python apps trying to use their own python versions? How relocatable is python? Fairly relocatable. If there is was a merge module, I'd really prefer it to be shared. The challenge here is site-packages: different users of the merge module would need different copies of site-packages (or else installing additional packages might break existing software). Another challenge with shared location merge modules is upgrades: the Python installer currently doesn't use stable component IDs; I think this would cause problems for users of the merge module. Providing stable component IDs is a challenge since it's difficult to version the files on disk. Not sure why Michael thinks that a private location merge module would provide no benefits to the user of the merge module. The maintenance nightmare isn't on your end (in my case), it would be on me to provide patches/upgrades. I do agree that patches w/ merge modules are a pain/nightmare. But what about providing both a merge module and msi so developers have a choice? I certainly wouldn't stop providing an MSI. The next question would be whether the MSI then also installs into the shared location, or whether it would have a private copy of Python. I work on open source projects myself, and we always provide both a merge module and a normal msi installer. It's very little extra work (in WiX at least) to create both. But what's the quality of these? Ideally, I'd like to create a single merge module which, at the option of the user of the merge module, produces either a shared or a private installation.
