edsp: optionally store a compressed copy of the last scenario

2016-06-08T11:07:21Z

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.

edsp: prevent it from trying to write a cache

2016-06-06T13:54:06Z

EDSP(-like) protocols are one-shot processes working on data which exists only as long as they run (as they get feed via a pipe), so trying to write a cache for it is pretty pointless, especially as it will usually fail as the cache files tend to be owned by root, but the process is run as a unpriviledged user (either _apt if called by root, otherwise the user of the caller). So this was in fact only observeable with our testcases which run as non-root and the worst which happens is that a valid cache is overridden with an invalid one which the next run will detect and not use.

refactor EDSP classes for better internal reuse

2016-06-05T11:15:55Z

The classes are all marked as hidden, so changing them is no problem ABI wise and will help with introducing protocols similar to EDSP. The change has no observeable behavior difference, its just code juggling. Git-Dch: Ignore

edsp: use an ID mapping for the internal solver

2016-06-04T16:45:01Z

Currently an EDSP solver gets send basically all versions which means the absolute count is the same, but that might not be true forever (and with the skipping of rc-only versions it kinda is already) and even if it were true, segfaulting on bad input seems wrong.

edspsystem.cc: include for mkdtemp

2016-02-03T22:46:19Z

Include to ensure that mkdtemp(3) is defined to improve general portability and fix a specific build failure on Android. Closes: #807367

remove unused Description methods in listparsers

2016-01-26T20:58:57Z

These virtual methods are implemented in hidden classes, so we can drop them without breaking the ABI. Git-Dch: Ignore

wrap every unlink call to check for != /dev/null

2015-11-04T17:42:28Z

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

sanify API to get 'the' candidate version

2015-11-04T17:04:05Z

This was discussed a while ago on #debian-apt and now that I see myself making this mistake lets bite the bullet and fix it in the easy way out version: Using a new name which fits with a similar named setter and deprecate the old method instead of 'hostily' changing API. Closes: #803471

use a less generic special trigger filename for stdin

implement autobit and pinning in EDSP solver 'apt'

2015-09-14T13:22:18Z

The parser creates a preferences as well as an extended states file based on the EDSP scenario file, which isn't the most efficient way of dealing with this as thes text files have to be parsed again by another layer of the code, but it needs the least changes and works good enough for now. The 'apt' solver is in the end just a test solver like dump.
