The following post is a verbatim copy of my message to the debian-devel list.
While botch produces loads of valuable data to help maintainers modifying the right source packages with build profiles and thus make Debian bootstrappable, it has so far failed at producing this data in a format which is:
- human readable (nobody wants to manually go through 12 MB of JSON data)
- generated automatically periodically and published somewhere (nobody wants to run botch on his own machine or update periodically update the TODO wiki page)
- available on a per-source-package-basis (no maintainer wants to know about the 500 source packages he does NOT maintain)
While human readability is probably still lacking (it's hard to write in a manner understandable by everybody about a complicated topic you are very familiar with), the bootstrapping results are now generated automatically (on a daily basis) and published in a per-source-package-basis as well. Thus let me introduce to you:
For now it is funny to see that the main architectures do not bootstrap (since July, for different reasons) while less popular ones like ia64 and s390x bootstrap right now without problems (at least in theory). According to the logs (also accessible at above link, here for amd64) this is because gcc-4.6 currently fails compiling due to a build-conflict (this has been reported in bug#724865). Once this bug is fixed, all arches should be bootstrappable again. Let me remind you here that the whole analysis is done on the dependency relationships only (not a single source package is actually compiled at any point) and compilation might fail for many other reasons in practice.
It has been the idea of Paul Wise to integrate this data into the pts so that maintainers of affected source packages can react to the heuristics suggested by botch. For this purpose, the website also publishes the raw JSON data from which the HTML pages are generated (here for amd64). The bugreport against the bts can be found in bug#728298.
I'm sure that a couple of things regarding understandability of the results are not yet sufficiently explained or outright missing. If you see any such instance, please drop me a mail, suggesting what to change in the textual description or presentation of the results.
I also created the following two wiki pages to give an overview of the utilized terminology:
Feel also free to tell me if anything in these pages is unclear.
Direct patches against the python code producing the HTML from the raw JSON data are also always welcome.
