| tsimonq2 | hi, I have a question about the API | 18:50 |
|---|---|---|
| tsimonq2 | I am looking to build an app that scans certain packages in the supported releases of Ubuntu for new versions and if so, then prints a message | 18:50 |
| tsimonq2 | is there a way in the API to see a package version? | 18:51 |
| tsimonq2 | I see the entry for Xenial, with it being the current release, but how about implementing Trusty, Vivid, and Wily? | 18:52 |
| tsimonq2 | if someone could get back to me soon, that would be great. THanks! | 18:52 |
| cjwatson | I would suggest using https://launchpad.net/+apidoc/devel.html#archive-getPublishedSources with order_by_date=True, and work backward until you hit stuff you've previously seen (being aware that you might see the same publication twice) | 18:52 |
| cjwatson | trusty, vivid, and wily are perfectly well implemented :) | 18:52 |
| tsimonq2 | cjwatson: all I see is current_version, what about calling it for those previous codenames? | 18:53 |
| cjwatson | current_version on what object, please? | 18:53 |
| cjwatson | there is no object with an attribute by that name on the API | 18:54 |
| cjwatson | do you mean current_series? | 18:54 |
| tsimonq2 | this is my current code: https://raw.githubusercontent.com/tsimonq2/lububot/master/test.py | 18:54 |
| tsimonq2 | I have to go now, I will be back in a couple of hours, please let me know | 18:54 |
| tsimonq2 | thank you | 18:54 |
| cjwatson | tsimonq2: use ubuntu.getSeries(name_or_version='wily') etc. | 18:54 |
| tsimonq2 | ok, thanks | 18:55 |
| cjwatson | tsimonq2: that code will be extremely very very very slow on lots of packages | 18:55 |
| tsimonq2 | hmm pok | 18:55 |
| cjwatson | I mean, if you're calling it on lots of packages | 18:55 |
| tsimonq2 | s/pok/ok/ | 18:55 |
| cjwatson | many many round trips | 18:55 |
| tsimonq2 | yep :) | 18:55 |
| cjwatson | if it's only a few, that's ok | 18:55 |
| tsimonq2 | I have a plan ;) | 18:55 |
| cjwatson | but if you're intending to check lots of packages, my recommendation above standas | 18:55 |
| cjwatson | *stands | 18:56 |
| cjwatson | archive.getPublishedSources(order_by_date=True, status="Published") and iterate | 18:56 |
| cjwatson | also, you should probably be using status="Published" in any case | 18:57 |

| tsimonq2 | cjwatson: hmm, what if I wanted to do a lot of packages? | 23:10 |
| tsimonq2 | cjwatson: any faster alternative? | 23:10 |
| cjwatson | tsimonq2: so, for that you're going to need to explain a bit more about exactly what your app is going to do | 23:12 |
| tsimonq2 | cjwatson: I would like my app(Python) to idle and print the package name when there is an update to a large amount of packages | 23:14 |
| tsimonq2 | or to that package | 23:14 |
| tsimonq2 | so when a package gets an update, I want an output | 23:14 |
| tsimonq2 | similar to queuebot | 23:15 |
| sarnold | isn't there a -changes mail list of some sort that publishes updates and new packages? | 23:16 |
| sarnold | e.g. https://lists.ubuntu.com/mailman/listinfo/trusty-changes | 23:16 |
| cjwatson | tsimonq2: so, there aren't currently good solutions that don't involve polling, but if you're prepared to poll every n minutes or something, then I gave you the faster alternative above - archive.getPublishedSources(order_by_date=True) basically tells you about everything recent in the archive, a bit like a fairly stupid RSS feed, and you walk back through it until you reach the thing you last heard of or a date cut-off | 23:16 |
| cjwatson | (or, yes, if you're prepared to subscribe to a mailing list as part of this then you can do that, but that's cumbersome from an app | 23:17 |
| cjwatson | ) | 23:17 |
| tsimonq2 | cjwatson: but then how would I parse that for the packages that I want? | 23:17 |
| wgrant | What do you mean? | 23:18 |
| cjwatson | tsimonq2: each entry in the collection is a source_package_publishing_history, so you look at the source_name attribute or whatever it's called | 23:18 |
| wgrant | It returns a list of entries, and you'd check the package name in each. | 23:18 |
| cjwatson | you don't need to "parse" | 23:18 |
| tsimonq2 | oh | 23:18 |
| tsimonq2 | ok | 23:18 |
| cjwatson | now, if you're planning for this app to be installed on lots and lots of systems, er, please warn us | 23:19 |
| cjwatson | 'cos maybe we want something more scalable in that kind of case ... | 23:19 |
| tsimonq2 | cjwatson: no, actually I plan on this being an IRC bot | 23:19 |
| cjwatson | (and you want status="Published" on that too, so that you don't get entries for things that are superseded etc.) | 23:19 |
| cjwatson | right, this should be fine for an IRC bot. it's what the ddebs.ubuntu.com publishing backend uses to keep up with the archive | 23:20 |
| tsimonq2 | cjwatson: so I want it to be as frequent as possible updates for that | 23:20 |
| cjwatson | and indeed we designed it for that purpose | 23:20 |
| tsimonq2 | cjwatson: so as I am not that familiar with working with APIs, how would I carry out that task(in code terms)? | 23:21 |
| tsimonq2 | cjwatson: so maybe source_package_publishing_history.sourcename? | 23:24 |
| tsimonq2 | cjwatson: or what? | 23:25 |
| tsimonq2 | cjwatson: but more specifically, when using the docs, how do I use the URLs given? | 23:28 |
| tsimonq2 | cjwatson: I just lack this knowledge, so if you could point me in the right direction, that would be awesome | 23:30 |
| tsimonq2 | or anyone else | 23:36 |
| wgrant | tsimonq2: https://help.launchpad.net/API/launchpadlib | 23:39 |
| tsimonq2 | wgrant: thank you | 23:47 |
| sarnold | https://bugs.launchpad.net/aptdaemon/+bug/659438 got some spam and fairly impolite replies from users; can this bug be made silent in some fashion? perhaps https://launchpad.net/~tegosfentasio and https://launchpad.net/~jc4 and https://launchpad.net/~ishani-infoware don't need to participate in launchpad any more either (comments 170, 172, 174) | 23:53 |
| wgrant | sarnold: Well that's pretty spectacular. | 23:54 |
| sarnold | pleasant people all around, right? | 23:55 |
| wgrant | sarnold: I've removed the comments, let me know if it continues. | 23:55 |
| wgrant | Indeed. | 23:55 |
| sarnold | wgrant: thanks! | 23:55 |
| wgrant | And all from some innocuous spam. | 23:55 |
| sarnold | no kidding; even without understanding ukranian it was obviously spam.. sigh. | 23:56 |
