PyPi not allowing duplicate filenames
by Chris Barker April 20, 2020

April 20, 2020

Hi all, PyPi does not allow duplicate file names -- this makes lots of sense, because you really don't want people to go to PyPi one day and grab a file, and then go there another day, grab a file with exactly the same name, and have it be a different file. However.... We are all too human, and make mistakes when doing a release. All to often someone pushed a broken file up to PyPi, often realizes it pretty quickly -- before anyone has a chance to even download it (or only the dev team as, for testing...). In fact, I was in a sprint last summer, and we decided to push our package up to PyPi -- granted, we were all careless amateurish noobs, but we ended up making I think 4! minor version bumps because we had done something stupid in the sdist. Also -- the latest numpy release got caught in this, too: """ * We ran into a problem with pipy not allowing reuse of filenames and a resulting proliferation of *.*.*.postN releases. Not only were the names getting out of hand, some packages were unable to work with the postN suffix. """ So -- I propose that PyPi allow projects to replace existing files if they REALLY REALLY want to. You should have to jump through all sorts of hoops, and make it really clear that it is a BAD IDEA in the general case, but it'd be good to have it be possible. After all -- PyPi does not take on responsibility for anything else about what's in those packages, and Python itself is all about "we're all consenting adults here" I suppose we could even put in some heuristics about how long the file as been there, how many times it's been downloaded, etc. Just a thought.....I really hate systems that don't let me roll back mistakes, even when I discover them almost immediately... -CHB -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception Chris.Barker(a)noaa.gov

ImportError running 'test' on namespace package - other package in namespace not found
by Jason R. Coombs April 17, 2020

April 17, 2020

I've got two projects: mynamespace.myprojectA and mynamespace.myprojectB myprojectB depends on myprojectA. I'm using setuptools 0.6c8 to manage both projects. Both projects are registered using 'setup develop'. Both projects are accessible from an interactive interpreter: PS C:\Users\me\projects> python Python 2.5.2 (r252:60911, Feb 21 2008, 13:11:45) [MSC v.1310 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> import mynamespace.myprojectA >>> import mynamespace.myprojectB >>> from mynamespace.myprojectA import mymoduleZ However, when I run 'setup test' in myprojectB, the tests fail with File ".mymoduleZ.py", line NNN, in [some context] from mynamespace.myprojectA.mymoduleZ import MyClassC ImportError: No module named myprojectA.mymoduleZ In setup.py, the test_suite is nose.collector. I searched and couldn't find anyone else with this problem. Is this a supported configuration? Is there something I can do to make tests work with interdependent projects with the same root namespace? If there's not something obvious I should be doing differently, I'm happy to put together a minimal test case that reproduces the problem. Any suggestions are appreciated. Sincerely, Jason R. Coombs

Surviving a Compromise of PyPI - PEP 458 and 480
by Vladimir Diaz Feb. 12, 2020

Feb. 12, 2020

Hello everyone, I am a research programmer at the NYU School of Engineering. My colleagues (Trishank Kuppusamy and Justin Cappos) and I are requesting community feedback on our proposal, "Surviving a Compromise of PyPI." The two-stage proposal can be reviewed online at: PEP 458 http://legacy.python.org/dev/peps/pep-0458/ PEP 480 http://legacy.python.org/dev/peps/pep-0480/ Summary of the Proposal: "Surviving a Compromise of PyPI" proposes how the Python Package Index (PyPI) can be amended to better protect end users from altered or malicious packages, and to minimize the extent of PyPI compromises against affected users. The proposed integration allows package managers such as pip to be more secure against various types of security attacks on PyPI and defend end users from attackers responding to package requests. Specifically, these PEPs describe how PyPI processes should be adapted to generate and incorporate repository metadata, which are signed text files that describe the packages and metadata available on PyPI. Package managers request (along with the packages) the metadata on PyPI to verify the authenticity of packages before they are installed. The changes to PyPI and tools will be minimal by leveraging a library, The Update Framework <https://github.com/theupdateframework/tuf>, that generates and transparently validates the relevant metadata. The first stage of the proposal (PEP 458 <http://legacy.python.org/dev/peps/pep-0458/>) uses a basic security model that supports verification of PyPI packages signed with cryptographic keys stored on PyPI, requires no action from developers and end users, and protects against malicious CDNs and public mirrors. To support continuous delivery of uploaded packages, PyPI administrators sign for uploaded packages with an online key stored on PyPI infrastructure. This level of security prevents packages from being accidentally or deliberately tampered with by a mirror or a CDN because the mirror or CDN will not have any of the keys required to sign for projects. The second stage of the proposal (PEP 480 <http://legacy.python.org/dev/peps/pep-0480/>) is an extension to the basic security model (discussed in PEP 458) that supports end-to-end verification of signed packages. End-to-end signing allows both PyPI and developers to sign for the packages that are downloaded by end users. If the PyPI infrastructure were to be compromised, attackers would be unable to serve malicious versions of these packages without access to the project's developer key. As in PEP 458, no additional action is required by end users. However, PyPI administrators will need to periodically (perhaps every few months) sign metadata with an offline key. PEP 480 also proposes an easy-to-use key management solution for developers, how to interface with a potential build farm on PyPI infrastructure, and discusses the security benefits of end-to-end signing. The second stage of the proposal simultaneously supports real-time project registration and developer signatures, and when configured to maximize security on PyPI, less than 1% of end users will be at risk even if an attacker controls PyPI and goes undetected for a month. We thank Nick Coghlan and Donald Stufft for their valuable contributions, and Giovanni Bajo and Anatoly Techtonik for their feedback. Thanks, PEP 458 & 480 authors.

Upgrading dependencies
by Charlie Moad April 29, 2018

April 29, 2018

Is it currently possible to upgrade dependencies as well when upgrading a packages? If not, this would be a really nice feature to add to easy_install. Maybe a call like: easy_install --upgrade --upgrade-deps Package Obviously it makes sense to leave this off by default. Thanks, Charlie

Changes to --find-links and --upgrade in SVN
by Phillip J. Eby April 29, 2018

April 29, 2018

Elvelind Grandin reported a problem with the "develop" command that turned out to be a flaw in its --find-links support. Specifically, it wasn't ever processing the links. :) In the process of fixing it, I wound up cleaning up an annoying (to me, at least) quirk of the previous workings of --find-links. It used to be that find-links would always be processed first, no matter what, even if you were doing a completely local operation. This would've been especially annoying if it carried over into "develop", so I made some changes. Now, if an item passed to --find-links is local (a filename or file: URL), or a direct link to an egg or other distribution, it is indexed immediately. Remote URLs are now only retrieved if a dependency can't be resolved locally, or if you use the -U or --upgrade options (this goes for "develop" too). Note that this is a behavior change for easy_install, which was effectively treating --find-links as though you'd specified --upgrade in certain cases. So, if you're used to getting upgrades downloaded as a result of using --find-links, please note that this will no longer happen. EasyInstall will now *only* go online if a dependency can't be resolved locally, if -U or --upgrade is used, or if you provided suitable direct URLs via an argument or --find-links, or via a link in a local .html file.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm new to distutils/and the egg system. I have not researched the archives as much as I should, so please excuse me if this is familiar territory...

Choice of dependencies?
by John J Lee April 29, 2018

April 29, 2018

Is it possible for a package to depend on one of several packages, with the user having the option to pick? For example, my package P might depend on package A, plus either package B or package C. I know I could (ab)use extras_require, but in my case this is a real dependency rather than an optional extra. The other option I have is to just pick one of the dependencies (B or C in my example above), and thereby force people to install it even though it's not strictly required. Neither option seems particularly attractive. John

Sample setup.py for Numeric Python
by Greg Ward April 29, 2018

April 29, 2018

Hi again -- [cc'd to Paul Dubois: you said you weren't following the distutils sig anymore, but this directly concerns NumPy and I'd like to get your input!] here's that sample setup.py for NumPy. See below for discussion (and questions!). ------------------------------------------------------------------------ #!/usr/bin/env python # Setup script example for building the Numeric extension to Python. # This does sucessfully compile all the .dlls. Nothing happens # with the .py files currently. # Move this file to the Numerical directory of the LLNL numpy # distribution and run as: # python numpysetup.py --verbose build_ext # # created 1999/08 Perry Stoll __rcsid__ = "$Id: numpysetup.py,v 1.1 1999/09/12 20:42:48 gward Exp $" from distutils.core import setup setup (name = "numerical", version = "0.01", description = "Numerical Extension to Python", url = "http://www.python.org/sigs/matrix-sig/", ext_modules = [ ( '_numpy', { 'sources' : [ 'Src/_numpymodule.c', 'Src/arrayobject.c', 'Src/ufuncobject.c' ], 'include_dirs' : ['./Include'], 'def_file' : 'Src/numpy.def' } ), ( 'multiarray', { 'sources' : ['Src/multiarraymodule.c'], 'include_dirs' : ['./Include'], 'def_file': 'Src/multiarray.def' } ), ( 'umath', { 'sources': ['Src/umathmodule.c'], 'include_dirs' : ['./Include'], 'def_file' : 'Src/umath.def' } ), ( 'fftpack', { 'sources': ['Src/fftpackmodule.c', 'Src/fftpack.c'], 'include_dirs' : ['./Include'], 'def_file' : 'Src/fftpack.def' } ), ( 'lapack_lite', { 'sources' : [ 'Src/lapack_litemodule.c', 'Src/dlapack_lite.c', 'Src/zlapack_lite.c', 'Src/blas_lite.c', 'Src/f2c_lite.c' ], 'include_dirs' : ['./Include'], 'def_file' : 'Src/lapack_lite.def' } ), ( 'ranlib', { 'sources': ['Src/ranlibmodule.c', 'Src/ranlib.c', 'Src/com.c', 'Src/linpack.c', ], 'include_dirs' : ['./Include'], 'def_file' : 'Src/ranlib.def' } ), ] ) ------------------------------------------------------------------------ First, what d'you think? Too clunky and verbose? Too much information for each extension? I kind of think so, but I'm not sure how to reduce it elegantly. Right now, the internal data structures needed to compile a module are pretty obviously exposed: is this a good thing? Or should there be some more compact form for setup.py that will be expanded later into the full glory we see above? I've already made one small step towards reducing the amount of cruft by factoring 'include_dirs' out and supplying it directly as a parameter to 'setup()'. (But that needs code not in the CVS archive yet, so I've left the sample setup.py the same for now.) The next thing I'd like to do is get that damn "def_file" out of there. To support it in MSVCCompiler, there's already an ugly hack that unnecessarily affects both the UnixCCompiler and CCompiler classes, and I want to get rid of that. (I refer to passing the 'build_info' dictionary into the compiler classes, if you're familiar with the code -- that dictionary is part of the Distutils extension-building system, and should not propagate into the more general compiler classes.) But I don't want to give these weird "def file" things standing on the order of source files, object files, libraries, etc., because they seem to me to be a bizarre artifact of one particular compiler, rather than something present in a wide range of C/C++ compilers. Based on the NumPy model, it seems like there's a not-too-kludgy way to handle this problem. Namely: if building extension "foo": if file "foo.def" found in same directory as "foo.c" add "/def:foo.def" to MSVC command line this will of course require some platform-specific code in the build_ext command class, but I figured that was coming eventually, so why put it off? ;-) To make this hack work with NumPy, one change would be necessary: rename Src/numpy.def to Src/_numpy.def to match Src/_numpy.c, which implements the _numpy module. Would this be too much to ask of NumPy? (Paul?) What about other module distributions that support MSVC++ and thus ship with "def" files? Could they be made to accomodate this scheme?

Can now compile simple extensions
by Greg Ward April 29, 2018

April 29, 2018

Hi all -- at long last, I found the time to hack in the ability to compile extension modules to the Distutils. Mainly, this meant adding a 'build_ext' command which uses a CCompiler instance for all its dirty work. I also had to add a few methods to CCompiler (and, of course, UnixCCompiler) to make this work. And I added a new module, 'spawn', which takes care of running sub-programs more efficiently and robustly (no shell involved) than os.system. That's needed, obviously, so we can run the compiler! If you're in the mood for grubbing over raw source code, then get the latest from CVS or download a current snapshot. See http://www.python.org/sigs/distutils-sig/implementation.html for a link to the code snapshot. I'm still waiting for more subclasses of CCompiler to appear. At the very least, we're going to need MSVCCompiler to build extensions on Windows. Any takers? Also, someone who knows the Mac, and how to run compilers programmatically there, will have to figure out how to write a Mac-specific concrete CCompiler subclass. The spawn module also needs a bit of work to be portable. I suspect that _win32_spawn() (the intended analog to my _posix_spawn()) will be easy to implement, if it even needs to go in a separate function at all. It looks from the Python Library documentation for 1.5.2 that the os.spawnv() function is all we need, but it's a bit hard to figure out just what's needed. Windows wizards, please take a look at the 'spawn()' function and see if you can make it work on Windows. As for actually compiling extensions: well, if you can figure out the build_ext command, go ahead and give it a whirl. It's a bit cryptic right now, since there's no documentation and no example setup.py. (I have a working example at home, but it's not available online.) If you feel up to it, though, see if you can read the code and figure out what's going on. I'm just hoping *I'll* be able to figure out what's going on when I get back from the O'Reilly conference next week... ;-) Enjoy -- Greg -- Greg Ward - software developer gward(a)cnri.reston.va.us Corporation for National Research Initiatives 1895 Preston White Drive voice: +1-703-620-8990 Reston, Virginia, USA 20191-5434 fax: +1-703-620-0913

Two fixes (at last)
by Greg Ward April 29, 2018

April 29, 2018

Hi all -- at long last, I have fixed two problems that a couple people noticed a while ago: * I folded in Amos Latteier's NT patches almost verbatim -- just changed an `os.path.sep == "/"' to `os.name == "posix"' and added some comments bitching about the inadequacy of the current library installation model (I think this is Python's fault, but for now Distutils is slavishly aping the situation in Python 1.5.x) * I fixed the problem whereby running "setup.py install" without doing anything else caused a crash (because 'build' hadn't yet been run). Now, the 'install' command automatically runs 'build' before doing anything; to make this bearable, I added a 'have_run' dictionary to the Distribution class to keep track of which commands have been run. So now not only are command classes singletons, but their 'run' method can only be invoked once -- both restrictions enforced by Distribution. The code is checked into CVS, or you can download a snapshot at http://www.python.org/sigs/distutils-sig/distutils-19990607.tar.gz Hope someone (Amos?) can try the new version under NT. Any takers for Mac OS? BTW, all parties involved in the Great "Where Do We Install Stuff?" Debate should take a good, hard look at the 'set_final_options()' method of the Install class in distutils/install.py; this is where all the policy decisions about where to install files are made. Currently it apes the Python 1.5 situation as closely as I could figure it out. Obviously, this is subject to change -- I just don't know to *what* it will change!

Package versioning
by Timothy Docker April 29, 2018

April 29, 2018

Hi all, I've been aware that the distutils sig has been simmerring away, but until recently it has not been directly relevant to what I do. I like the look of the proposed api, but have one question. Will this support an installed system that has multiple versions of the same package installed simultaneously? If not, then this would seem to be a significant limitation, especially when dependencies between packages are considered. Assuming it does, then how will this be achieved? I am presently managing this with a messy arrangement of symlinks. A package is installed with its version number in it's name, and a separate directory is created for an application with links from the unversioned package name to the versioned one. Then I just set the pythonpath to this directory. A sample of what the directory looks like is shown below. I'm sure there is a better solution that this, and I'm not sure that this would work under windows anyway (does windows have symlinks?). So, has this SIG considered such versioning issues yet?

Versioned trove classifiers for Django
by James Bennett April 6, 2017

April 6, 2017

Following up on some IRC discussion with other folks: There is precedent (Plone) for PyPI trove classifiers corresponding to particular versions of a framework. So I'd like to get feedback on the idea of expanding that, particularly in the case of Django. The rationale here is that the ecosystem of Django-related packages is quite large, but -- as I know all too well from a project I'm working on literally at this moment -- it can be difficult to ensure that all of one's dependencies are compatible with the version of Django one happens to be using. Adding trove classifier support at the level of individual versions of Django would, I think, greatly simplify this: tools could easily analyze which packages are compatible with an end user's chosen version, there'd be far less manual guesswork, etc., and the rate of creation of new classifiers would be relatively low (we tend to have one X.Y release/year or thereabouts, and that's the level of granularity needed). Assuming there's consensus around the idea of doing this, what would be the correct procedure for getting such classifiers set up and maintained?

namespace_package
by KP Sept. 12, 2016

Sept. 12, 2016

I'm not sure where the issue is, but when I specify a namespace_package in the setup.py file, I can indeed have multiple packages with the same base (foo.bar, foo.blah, etc...). The files all install in to the same directory. It drops the foo/__init__.py that would be doing the extend_path, and instead adds a ".pth" file that is a bit over my head. The problem is that it does not seem to traverse the entire sys.path to find multiple foo packages. If I do not specify namespace_packages and instead just use the pkgutil.extend_path, then this seems to allow the packages to be in multiple places in the sys.path. Is there something additional for the namespace_package that i need to specify in order for all of the sys.path to be checked? I'm using 18.5 setuptools....but I am not sure if this somehow ties in to wheel/pip, since I'm using that for the actual install.

Missing IPv6 support on pypi.python.org
by Baptiste Jonglez July 13, 2016

July 13, 2016

Hi, pypi.python.org is currently not reachable over IPv6. I know this issue was brought up before [1,2]. This is a real issue for us, because our backend servers are IPv6-only (clients never need to talk to backend servers, they go through IPv4-enabled HTTP frontends). So, deploying packages from pypi on the IPv6-only servers is currently a pain. What is the roadmap to add IPv6 support? It seems that Fastly has already deployed IPv6 [3]. Thanks, Baptiste [1] https://mail.python.org/pipermail/distutils-sig/2014-June/024465.html [2] https://bitbucket.org/pypa/pypi/issues/90/missing-ipv6-connectivity [3] http://bgp.he.net/AS54113#_prefixes6

deprecating pip install --target
by Robert Collins May 10, 2016

May 10, 2016

This is fairly broken - it doesn't handle platlib vs purelib (see pip PR 3450), doesn't handle data files, or any other layout. Donald says pip uses it to maintain the _vendor subtrees only, which doesn't seem like a particularly strong use case. Certainly the help description for it is misleading - since what we're actually doing is copying only a subset of what the package installed - so at a minimum we need to be much clearer about what it does. But, I think it would be better to deprecate it and remove it... so I'm pinging here to see if anyone can explain a sensible use case for it in the context of pip :) -Rob -- Robert Collins <rbtcollins(a)hpe.com> Distinguished Technologist HP Converged Cloud

wheel including files it shouldn't
by Ethan Furman May 10, 2016

May 10, 2016

I just received a bug report for enum34 for python3 code in a test file. Further research revealed that that file should not be included in the distribution, and is not included in the .tar nor .zip bundles, only the wheel bundle. Is this a known/fixed bug? If not, where do I report it? -- ~Ethan~

Use of direct references in requirements for setuptools
by Steve Kowalik April 28, 2016

April 28, 2016

Hi, Currently, pip supports use of direct references[1][2] in requirement files, which means it includes code that will deal with downloading files over HTTP, or git, etc. setuptools does not have this support, and in order for setuptools to completely implement PEP 508 support, we should come up with a plan what to do when setuptools encounters a requirement that uses a direct reference. The options that I can see are: 1) When egg_info is run, exit with an error saying "Please don't do that" 2) Warn about the requirement, and that we will just depend on it, but drop the direct reference. 3) Add support to setuptools. Personally, I don't like this plan, but perhaps it's easy. 1: For example: testtools@ https://github.com/testing-cabal/testtools 2: It doesn't yet support the format specified by PEP 508, but the functionality exists and works. -- Steve Oh, in case you got covered in that Repulsion Gel, here's some advice the lab boys gave me: [paper rustling] DO NOT get covered in the Repulsion Gel. - Cave Johnson, CEO of Aperture Science

Parked Names in PyPI under user rodmena
by Christopher Wilcox April 23, 2016

April 23, 2016

DistUtils-Sig: I was searching warehouse for all Microsoft owned packages today and came across a certain user that seems to have parked on a few different package names that I don’t believe he has any intention of using (@rodmena). https://warehouse.python.org/user/rodmena/ Can we get these released to the proper owners? He seems to have done this rather broadly. If possible can the user @Microsoft be marked as the owner of the Microsoft package? Thanks! Chris Wilcox
