devpi-{server-2.1.2,web-2.2.1}: bugfixes, streamlined web templates
by holger krekel 24 Oct '14

24 Oct '14

devpi-server-2.1.2 and devpi-web-2.2.1 bring a host of fixes to the private pypi server system. You can upgrade without migrating your data if you run already with devpi-server-2.1.X. Find docs as usual at: http://doc.devpi.net Many thanks to Florian Schulze who did most of the changes in devpi-web. Have fun, holger krekel, merlinux GmbH devpi-server-2.1.2 ------------------ - fix issue172: avoid traceback when user/index/name/version is accessed. - fix issue170: ensure that we parse the prospective pip-6.0 user agent string properly so that using the username/index url works with pip. Thanks Donald Stufft and Florian Schulze. - fix issue158: redirect to normalized projectname for all GET views. - fix issue169: change /+status to expose "event_serial" as "the last event serial that was processed". document "serial" and "event-serial" and also refine internals wrt to "event-serial" so that it means the "last serial for which events have been processed" devpi-web-2.2.1 --------------- - require devpi-server>=2.1.2 - fix issue175: use normalized name of projects, so redirects from unnormalized names works. NOTE that if you had issues with documentation uploads not appearing because of normalization issues ("-" or "_" appearing in the name for example) you need to re-upload the docs or do a full export/import cycle. - fix view when tox results can not be parsed. - version.pt: removed "code" tag around overwrite count. - macros.pt: added "footer" tag around the whole footer part. - version.pt: moved file type, python version and size info from their own columns into the file column. - version.pt: moved history column from before the tox results column to behind the tox results. - version.pt: removed "last modified" from history column - version.pt: removed timestamp from "replaced" action in history column - version.pt: add link to PyPI page if applicable. - fix project page view if there are downloads with filenames which can't be parsed as packages with version number - fix notfound-redirect when serving under an outside URL with a sub path

Indeed, enriching the tox result file and then parsing/reading it on the server side is probably the way to go. One related question is how to store the tox result files. Currently they are just tied to the sdist link (wheels cannot have tox.ini files to begin with) which was obtained from "devpi test" as the best matching link. But i think server-side we need to detach it (again) from the sdist link and rather store them indexed by the MD5 of the sdist content and also by the md5 of of all dependencies. The idea is to be able to efficiently: - query all test results where this release file (or release version) was a part of the (test) dependencies - query all "testing tasks" caused by changed dependencies (this could be polled from a new "devpi test-server" subcommand which executes "pending testing tasks" for the platform it runs on) - show and record dependency/test information even for root/pypi projects (like we used to) Changing the server storage and access methods for test results does not neccessarily change the client facing UI i think. We can still provide the same json but we produce it differently. > The only "unsafe" part I can think of is a general issue, malicious > archives which exhaust server resources. We can have an upper found because 640MB archives should be enough for anyone! But i think for wheels the reading of the metadata does not require full unpacking but just some lightweight iteration, anyway :) holger > Regards, > Florian Schulze > > > On 16 Oct 2014, at 13:08, holger krekel wrote: > > >Hi all, > > > >FYI i thought about how we make devpi-server know about which project > >depends on which other projects.

recording project dependencies
by holger krekel 16 Oct '14

16 Oct '14

Hi all, FYI i thought about how we make devpi-server know about which project depends on which other projects. With that information we could do all kinds of good things: - display depency info on the per-project web page or along with release files (this project depends on ProjectY and ProjectZ) - display if all recent versions of deps are properly working and tested with a project's latest release - could trigger server-side "dependency changed" events so that for example a tox run could be triggered for the new test configuration - create pin-versioned requirement files that could be used with "pip install -r tested-requirements.txt", and/or possibly a UI like "devpi rinstall X" where it would query the latest set of dependencies for which tests passed, download all according files and then run "pip install --no-index FILE1 FILE2 [...]" which wouldn't require any more network access. Question is how to best get the (closure) set of dependencies for a project. I cam currently pondering the following possibilities to obtain the information at server side: - if the project has release files as wheels, look at wheel metadata which lists deps (requires just virtually unzipping a wheel and looking at safe metadata files) - "devpi test" could run "setup.py egg_info" and send the requirements it finds to the server (requires login), additionally it should probably "pip list" all test dependencies in the respective tox environments and add them as well because if test dependencies change, tests should be re-run as well. These two methods would not require any change in client-facing UI and allow us to get and display the dependencies information. Any comments or thoughts on the matter welcome. best, holger

devpi-server-2.1.1: replication/url fixes
by holger krekel 15 Oct '14

15 Oct '14

Hi all, the caching and private pypi server, devpi-server-2.1.1, is out and fixes some bugs, see changelog below. It is fully backward compatible, no export/import cycle required. For more info, see http://doc.devpi.net. best, holger krekel, merlinux GmbH 2.1.1 ---------------- - fix replication issue reported by a customer: if a replica lags behind a master and a file was created and then deleted meanwhile, the replica could get stuck with a FileReplicationError. We now let the master report a 410 GONE code so that the replica knows it can safely proceed because the file was deleted later anyways. - generate "systemd" configuration example when "--gen-config" is issued. Thanks Pavel Sedlak. - fix issue109: fix relative URLs in simple index pages and 404 errors on uploading toxresults and downloading files when serving under an outside URL with a sub path. Thanks to Joe Holloway for detailed infos. - drop limitation on maximum documentation size. Body size is now only controlled by frontends such as nginx. Thanks Stephan Erb. - use newer version of virtualenv for jenkins trigger. Thank brunsgaard.

Dockerizing devpi
by José Luis Lafuente 14 Oct '14

14 Oct '14

Hi! I'm running devpi in docker, and I wrote a little project to manage the docker containers. It serves devpi through nginx with https by default, and my idea was to simplify the installation and maintenance of devpi. Maybe is useful to someone else, a link to the project: https://github.com/jlesquembre/devpi-docker Regards, José Luis Lafuente

Feature request: Enable index shadowing via configuration or option
by Dan Haskin 14 Oct '14

14 Oct '14

I submitted this pull request <https://bitbucket.org/hpk42/devpi/pull-request/139/only-return-python-packa…> to devpi, which would cause devpi to "shadow" package versions across indexes. I will quote my description of the pull request here: Say I have package 'a' on index 'x' which lists index 'y' as a base index. That is, 'x' inherits from 'y'. A common use case is to want to install package 'a' from 'x' and 'y'. If I wanted the version of 'a' listed on in the 'y' index, I would have listed that index in my pip configuration. But I want the version of 'a' listed in index 'x', not 'y'. Currently, if I as a user point pip to index 'x', pip will only install 'a' from 'x' if the package 'a' is of a later version than the package 'a' listed in 'y'. But in our scenario, pip should always install the package 'a' listed in index 'x', not 'y', else there would be no need for multiple repositories at all. This patch fixes that. With this patch, if devpi is queried for a package 'a' from index 'x', it will get package 'a' from 'x' every time, even if a newer version of 'a' is listed in index 'y'. The pull request in its current form would have changed the way devpi pulls packages, and would have broken important workflows. However, for other workflows, I feel this feature is relevant and handy. I therefore request that: 1. The "shadow indexes" feature be added to devpi, although by default it be *turned off*. 2. The feature should/could be enabled either by command line option or configuration file. I think that index shadowing isn't something for everyone, but I think a lot of people would find it useful. We certainly would in our shop. Thanks

Automatic building of wheels? (discuss ;-)
by Richard Jones 12 Oct '14

12 Oct '14

Is it possible (or desirable) that devpi be able to trigger builds of wheels for packages that it caches? I realise it'd be possible as part of a Jenkins trigger for an upload, but this is for cached packages from PyPI. The actual building could be complex - in the case of current Linux wheels, we'd need to have separate indexes for the wheels for Debian, RHEL, Ubuntu, SUSE, etc. since the wheels are typically not compatible. That complexity could be external to devpi - it's just a case of getting the trigger to indicate that a build is desired. Quite how this integrates with a user just doing a "pip install package" is a little beyond me for the moment - the delay between the cache event and build completing could be significant. In light of that it might be desirable to have a separate process which does all this work (fetches the latest package and performs the build). Has anyone done this? How would it keep up to date?

testing wheel files / refinements
by holger krekel 01 Oct '14

01 Oct '14

Hi all, Currently you can't use "devpi test" with wheel files because they don't contain the tests unless you put all tests inside the software archive. To get the tests we could require that there is an "sdist" archive file containing the "tox.ini" file and the tests. Thus "devpi test X" would potentially download two files, a platform specific one and the sdist to configure and perform testing. Apart from running the tests against the sdist we probably also want to run the tests against the installed sdist. Not sure i grasp all implications yet (also UI wise) but does anyone of you have preliminary thoughts on the issue? best, holger
