PEP 376 - RECORD format proposal
by Tarek Ziadé July 7, 2009

July 7, 2009

Hello, Let's state that we don't allow absolute paths in RECORD file and see what we can do with other paths. First as a reminder, here's the full list of directories used by Distutils at installation time. The "install" command uses five options to decide where to install the files. The default values are: Unix: install_purelib: sys.prefix/lib/python2.6/site-packages install_platlib: sys.exec_prefix/lib/python2.6/site-packages install_headers: sys.prefix/include/python2.6/docutils install_scripts: sys.prefix/bin install_data : sys.prefix Unix, using the home option, instead of sys.prefix/sys.exec_prefix: install_purelib: home/lib/python install_platlib: home/lib/python install_headers: home/include/python/$dist_name install_scripts: home/bin install_data : home Windows: install_purelib: sys.prefix/Lib/site-packages install_platlib: sys.prefix/Lib/site-packages install_headers: sys.prefix/Include/python2.6/docutils install_scripts: sys.prefix/bin install_data : sys.prefix There are also some old scheme for os.name in ('mac', 'os2') I need to cleanup asap in there, but I won't mention them. Last, there's now the new per user site-package that adds more potential locations. e.g. replaces sys.prefix and sys.exec_prefix with two user directories. So they are all located under two root locations at the max. But since these are all overridable options (in pydistutils.cfg, distutils.cfg, etc) files can be located under *five* different roots. So my proposal is to write those five roots in a header line in the RECORD file, and use them as prefixes to locate the files that are not under the directory where the egg-info dir is located (which will be kept : relative paths) purelib,xxx,headers,xxx,scripts,xxx,install_data,xxx ... $purelib/some/file ... How does that sounds ? Tarek. -- Tarek Ziadé | http://ziade.org

PEP 376 - Open questions
by Paul Moore July 7, 2009

July 7, 2009

As promised, here are some open questions on PEP 376. - Will the public API names be changed from *egginfo* to *metadata*? - What precisely are the use cases for absolute path names? Concrete examples are needed. With the current spec, some things can go wrong (e.g., see below), so we need real use cases to know how to address this. - How will bdist_wininst/bdist_msi/bdist_rpm be updated? - How will the RECORD file be managed? (Particularly for the case of bdist_xxx) [1] - Can distutils be made to install files in places the current RECORD file spec can't handle? (I think the answer is "yes"). What happens then? - Should distribution names be case insensitive on case insensitive filesystems? For comparison, module/package names are always case sensitive even on case insensitive systems. - What will happen with the md5 hash? Are more types of hash going to be supported? What's the default? (Actually, the PEP doesn't need to care about the default, as the PEP says nothing about how RECORD files are written). [1] Note - the idea of using $EXEC_PREFIX / $PREFIX implies that the RECORD file is intended to be relocatable. Which is worrying, and also implies that an individual Distribution class must be able to handle filesystem files as well as whatever else it handles (consider mylib.zip on sys.path, containing a distribution which installed some files in $PREFIX). If this isn't possible, it should be clearly stated that it isn't possible. If it is, the ramifications are complex... I'm still unsure how the local vs relative, slash-separated filename formats should be handled. I don't actually think there's any real benefit in having 2 formats. I propose: - get_installed_files(), uses(), get_file_users() - always use local format absolute pathnames (for zipfiles and the like, these may not be "real" filenames, but they will be in "real filename" format, so other code will be able to manipulate them as filenames). - get_egginfo_files, get_egginfo_file - always use slash-separated forms, relative to the egginfo directory (so the name of the RECORD file is just 'RECORD') But there could be uses I haven't thought about, so this still counts as an open question at the moment (i.e., I'm reluctant to implement things this way until I've had some feedback).

You misunderstand me. The whole point of putting .egg-info in distutils in the first place was to enable setuptools to detect the presence of disutils-installed packages. That's what's broken by changing the name.

If you want a clearer name, '.pydist' or some such would at least be reasonably specific. (It'd still have a backward compatibility problem, but at least then there'd be some benefit to the name change.)

The purpose is to be able to remove scripts, data files, documentation, etc. that's stored in some place that's not package-relative, and survive a move of the package directory itself. For example, suppose I install with --prefix=~, and have files in ~/bin and ~/lib. I then move ~/lib/python2.7 to ~/pylib. If the scripts were installed with a relative path, this would break the link to the script still living in ~/bin. Now that I'm thinking about this, it occurs to me that there is another way to address this besides mixing relative and absolute paths in RECORD, and that is to make *all* the paths relative, and include an original installation location in INSTALLER. Then, it would be possible to detect whether the installation location had been moved and handle it accordingly... for some definition of "accordingly". I agree that further discussion is probably needed to resolve this. >- How will bdist_wininst/bdist_msi/bdist_rpm be updated? bdist_wininst, bdist_dumb, and various others use 'install --root' pattern to generate files for installation, which means that they would transparently end up writing a correct RECORD file, except for the inclusion of incorrect absolute paths for non-libdir-relative files. However, if we used the "all relative in RECORD, with a base in INSTALLER", these cases could transparently be treated as another instance of install directory relocation. I don't know if bdist_msi does a --root install before generating the .msi; if it does, then it should work the same way. >- Can distutils be made to install files in places the current RECORD >file spec can't handle?

IMO, they should be case-insensitive *regardless* of filesystem case, and I believe PyPI has already begun disallowing packages with only case-distinct names (e.g. 'Zope' vs. 'ZoPe') to be registered.

The only practical difference between the existing formats and the proposed new one (AFAICR) is the extension of the directory name, and the presence or absence of the RECORD file. My POV is that it would be a shame to discard compatibility with existing installed software, just for a bikeshedding of the directory name. Especially if it means that any tools that currently generate .egg-info's (and I'm not 100% positive setuptools is the only case) will need to grow options for whether to generate the old name, possibly based on what Python version... except you can install new distutils into old Python... etc. If this were strictly a matter of, "from Python 3.x on, generate .pydist", it's a lot less of a problem for me and everybody else, because Python 3 is effectively going to force a fork (or at least a branch) of setuptools anyway. For Python 2.x, having *two* names for .egg-info (which is what I understand the proposal to effectively be) is just asking for trouble, IMO. And my concern is that currently these compatibility issues are being handwaved rather than considered up front. To reiterate, summarize, and attempt to make as concrete as I can: I'm fine with a rename, *if and only if* it can be done in a way that never requires a tool to generate BOTH files for compatibility reasons. AFAICT, this can only be done by making the extension dependent upon the Python version, and this version distinction must be made *even if* the distutils themselves are backported to an earlier Python version. (Alternatively, this could be resolved by *not* backporting the PEP 376-compatible distutils/pkgutil to 2.x.) Currently, there is no official Python 3 release of setuptools, so compatibility can (IMO) be considered moot there. What's more, it is easy to conditionally determine whether to use '.egg-info' or '.pydist' based on Python version. What is not easy and likely to be confusing for everyone, is having the possibility for *both* to exist in the same system, *without* also having bidirectional interoperability. So, I'm +1 for no change (obviously), and +0 for "always .pydist in 3.x and always .egg-info in 2.x", whether the latter part is achieved by making distutils/pkgutil use a version-dependent extension, or by refusing to backport distutils/pkgutil to 2.x. I'm -1 for having .pydist ever appear on a 2.x Python, either via stdlib or backporting. (These comments also apply for any name other than '.pydist'.) Footnote: there has been some discussion that implies that somehow .egg-info was hijacked into the stdlib, and that it should therefore not be supported. This is incorrect: at Pycon the year this happened (2005 IIRC), Guido *blessed setuptools for inclusion in the stdlib* in his keynote. Yes, *all* of setuptools, including easy_install, eggs, the whole nine yards. A few months later, when I actually checked in the code, there were protests from a few people on Python-Dev, some of which I agreed were valid. I reverted the checkin, floating instead a compromise proposal to add .egg-info support to distutils (i.e. the install_egg_info command) to allow setuptools and other 3rd party tools to detect the presence of distutils-installed packages. At the time, the assumption was that eggs and setuptools would still, eventually, make it into the stdlib -- at the time, Guido had not yet changed his mind about that. So the ".egg-info" name was not controversial, to the best of my recollection, and the inclusion did not violate any of the expressed concerns of the three persons who objected to including setuptools whole-hog. So, from my POV at least, dropping .egg-info is dropping backward compatibility on a feature that was *intentionally* added to the stdlib -- with approval from Guido and non-protest from Python-Dev -- specifically to provide that compatibility. That doesn't obligate it to stay... but I suggest that it *does* mean Python 3, not 2, is the appropriate place for dropping it (if it is indeed to be dropped)... and that it is not appropriate to do so in 2.x on merely a handwave by persons not involved in the previous discussions. (And of course Guido can Pronounce otherwise; I'm just saying I don't think anything less than such a pronouncement is required to remove it from 2.x. And again, I'm fine with making a clean break of it in 3.x, since setuptools is already broken there anyway.)

I assume you are using signals in your application? The os.read above is not the only system call that can fail with EINTR. subprocess.py is full of other system calls that can fail, and I suspect that many other Python modules are as well. I've made a patch (attached) to subprocess.py (and test_subprocess.py) that should guard against EINTR, but I haven't committed it yet. It's quite large. Are Python modules supposed to handle EINTR? Why not let the C code handle this? Or, perhaps the signal module should provide a sigaction function, so that users can use SA_RESTART.

Your proposal, as I understood it, was that pkgutil would not detect .egg-info's without a plugin of some sort... and you've not proposed a way of loading such a thing, which means that to use pkgutil with that plugin, an application would have to know that the plugin exists and import it. Unless you're planning to have a plugin registration facility (ala entry points) so that plugins can be used without each application needing to discover them on its own?

The existing versions of setuptools will read a file or a directory with no problem; it's the name change that will require a code change, and it's a rather more complex issue than just one name change, because it'll need to support both names. What's more, on the build/install side, it'll have to figure out whether to use the new name or the old name when creating a project's metadata for installation in single-version mode. In other words, this will likely affect pip as well, or at least the parts of setuptools that pip uses. >My site-packages has a confusing mix of egginfo directories and files. >Note that I NEVER use setuptools other than where an existing >package's setup.py requires it.

I'm all in favor of adding RECORD support to setuptools; it was in fact my idea to have the file there in the first place. Adding a RECORD file doesn't introduce any new and weird name migration requirements, which is why I'd rather not change the extension if we can avoid it. Reading both names is painful, writing both is more so, and I'm not sure how many tools/users *besides* setuptools will be affected by a name change. > > How much information does setuptools actually need in order to tell that > > a distribution is already present?

Setuptools treats an .egg-info file as if it were a PKG-INFO file contained in an .egg-info directory. This allows it to treat distutils-supplied .egg-info files as if they were setuptools-supplied .egg-info directories containing exactly one file.
