apt(8): Wait for frontend and cache lock

2020-02-26T19:36:52Z

This is a rework of !6 with additional stuff for the frontend lock, so we can lock the frontend lock and then keep looping over dpkg lock.

Add support for dpkg frontend lock

2018-08-07T13:07:52Z

The dpkg frontend lock is a lock dpkg tries to acquire except if the frontend already acquires it. This fixes a race condition in the install command where the dpkg lock is not held for a short period of time between different dpkg invocations. For this reason we also define an environment variable DPKG_FRONTEND_LOCKED for dpkg invocations so dpkg knows not to try to acquire the frontend lock because it's held by a parent process. We can set DPKG_FRONTEND_LOCKED only if the frontend lock really is held; that is, if our lock count is greater than 0 - otherwise an apt client not using the LockInner family of functions would run dpkg without the frontend lock set, but with DPKG_FRONTEND_LOCKED set. Such a process has a weaker guarantee: Because dpkg would not lock the frontend lock either, the process is prone to the existing races, and, more importantly, so is a new style process. Closes: #869546 [fixups: fix error messages, add public IsLocked() method, and make {Un,}LockInner return an error on !debSystem]

Reformat and sort all includes with clang-format

2017-07-12T11:57:51Z

This makes it easier to see which headers includes what. The changes were done by running git grep -l '#\s*include' \ | grep -E '.(cc|h)$' \ | xargs sed -i -E 's/(^\s*)#(\s*)include/\1#\2 include/' To modify all include lines by adding a space, and then running ./git-clang-format.sh.

Drop cacheiterators.h include

2017-07-12T11:56:05Z

Including cacheiterators.h before pkgcache.h fails because pkgcache.h depends on cacheiterators.h.

provide public interface to hold/unhold packages

2015-11-04T17:04:00Z

We had this code lying around in apt-mark for a while now, but other frontends need this (and similar) functionality as well, so its high time that we provide a public interface in libapt for this stuff.
