2016-06-08edsp: drop privileges before executing solversDavid Kalnischkies
Most (if not all) solvers should be able to run perfectly fine without root privileges as they get the entire state they are supposed to work on via stdin and do not perform any action directly, but just pass suggestions on via stdout. The new default is to run them all as _apt hence, but each solver can configure another user if it chooses/must. The security benefits are minimal at best, but it helps preventing silly mistakes (see 35f3ed061f10a25a3fb28bc988fddbb976344c4d) and that is always good. Note that our 'apt' and 'dump' solver already dropped privileges if they had them.
2016-06-08edsp: optionally store a compressed copy of the last scenarioDavid Kalnischkies
For bugreports and co it could be handy to have the scenario and all the settings used in it around later for inspection for EDSP like protocols. EDSP might not be the most interesting as the user can still interrupt the process before the solution is applied and users tend to have an opinion on the "rightness" of a solution, so it is disabled by default.
2016-05-20edsp: dump: support dumping into compressed fileDavid Kalnischkies
2016-05-20convert EDSP to be based on FileFd instead of FILE*David Kalnischkies
I doubt there is any non-src:apt usage of these interfaces.
2015-11-04wrap every unlink call to check for != /dev/nullDavid Kalnischkies
Unlinking /dev/null is bad, we shouldn't do that. Also, we should print at least a warning if we tried to unlink a file but didn't manage to pull it of (ignoring the case were the file is /dev/null or doesn't exist in the first place). This got triggered by a relatively unlikely to cause problem in pkgAcquire::Worker::PrepareFiles which would while temporary uncompressed files (which are set to keep compressed) figure out that to files are the same and prepare for sharing by deleting them. Bad move. That also shows why not printing a warning is a bad idea as this hide the error for in non-root test runs. Git-Dch: Ignore

And of course, testing obscure things ends up showing obscure 'bugs' or better shortcomings/inconsitencies, so lets fix them with the tests. Git-Dch: Ignore
2015-09-14fix insecure use of /tmp in EDSP solver 'dump'David Kalnischkies
As said in the bugreport, this is hardly a serious problem on a security front, but it was always on the list to have the filename configurable somehow and the stable filename is a problem for parallel executions. Using an environment variable (APT_EDSP_DUMP_FILENAME) for this is more or less the best we can do here as solvers do not get told about our configuration and such. Closes: 795600
2015-03-16stop displaying time of build in online helpJérémy Bobbio
As part of the “reproducible builds” effort [1], we have noticed that apt could not be built reproducibly. One issue is that it uses the __DATE__ and __TIME__ macros of the C preprocessor to display the time of build in the online help. We believe this information not to be really useful to users as they can always look at the package data and metadata to figure it out. The attached patch simply removes this information. All non-documentation packages can then be built reproducibly with our current experimental framework. [David: changed the string slightly to be untranslateable as well] Closes: 774342
