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.

Based on a discussion with Niels Thykier who asked for Contents-all this
implements apt trying for all architecture dependent files to get a file
for the architecture all, which is treated internally now as an official
architecture which is always around (like native). This way arch:all
data can be shared instead of duplicated for each architecture requiring
the user to download the same information again and again.
There is one problem however: In Debian there is already a binary-all/
Packages file, but the binary-any files still include arch:all packages,
so that downloading this file now would be a waste of time, bandwidth
and diskspace. We therefore need a way to decide if it makes sense to
download the all file for Packages in Debian or not. The obvious answer
would be a special flag in the Release file indicating this, which would
need to default to 'no' and every reasonable repository would override
it to 'yes' in a few years time, but the flag would be there "forever".
Looking closer at a Release file we see the field "Architectures", which
doesn't include 'all' at the moment. With the idea outlined above that
'all' is a "proper" architecture now, we interpret this field as being
authoritative in declaring which architectures are supported by this
repository. If it says 'all', apt will try to get all, if not it will be
skipped. This gives us another interesting feature: If I configure a
source to download armel and mips, but it declares it supports only
armel apt will now print a notice saying as much. Previously this was a
very cryptic failure. If on the other hand the repository supports mips,
too, but for some reason doesn't ship mips packages at the moment, this
'missing' file is silently ignored (= that is the same as the repository
including an empty file).
The Architectures field isn't mandatory through, so if it isn't there,
we assume that every architecture is supported by this repository, which
skips the arch:all if not listed in the release file.

Doing this disables the implicit copy assignment operator (among others)
which would cause hovac if used on the classes as it would just copy the
pointer, not the data the d-pointer points to. For most of the classes
we don't need a copy assignment operator anyway and in many classes it
was broken before as many contain a pointer of some sort.
Only for our Cacheset Container interfaces we define an explicit copy
assignment operator which could later be implemented to copy the data
from one d-pointer to the other if we need it.

To have a chance to keep the ABI for a while we need all three to team
up. One of them missing and we might loose, so ensuring that they are
available is a very tedious but needed task once in a while.

Its a bit unpredictable which permissons and owners we will encounter on
a CD-ROM (or a USB stick, as apt-cdrom is responsible for those too),
so we have to ensure in this codepath as well that everything is nicely
setup without waiting for a 'apt-get update' to fix up the (potential)
mess.

We autocreate for a while now the last two directories in /var/lib/apt/lists
(similar for /var/cache/apt/archives) which is very nice for systems having
any of those on tmpfs or other non-persistent storage. This also means
though that this creation is effected by the default umask, so for
people with aggressive umasks like 027 the directories will be created
with 750, which means all non-root users are left out, which is usually
exactly what we want then this umask is set, but the cache and lib
directories contain public knowledge. There isn't any need to protect
them from viewers and they render apt completely useless if not
readable.

In bug #740673 various issues in the CD-ROM handling code were
identified, while most the issues ended up being fixed in another way,
the unmounting of the CD-ROM in error cases was not tackled so far.
(The patch was modified by the commiter to apply)

fixes some messages and their translation so that all of them have three
dots for messages with an elipse. Many translations already had this.
|

Commit 62dcbf84 changed the code of ident to look more like the code for
add on my suggestion. This made ident interactive as it starts with a
unmount, press enter, mount cycle. The first two are skipped now.
This fixes d-i/apt-setup which is using it to get ID as well as label.
Closes: 740673

Beside being a bit cleaner it hopefully also resolves oddball problems
I have with high levels of parallel jobs.

If there are multiple CD-ROM drives, `apt-cdrom add` will abort with an
error if any of the drives do not contain a Debian CD which is against
the documentation we have saying "a CD-ROM" and also scripts do not
expect it this way.
This patch modifies apt-cdrom to return success if any of the drives
succeeded. If failures occur, apt-cdrom will still continue trying all
the drives and report the last failure (if none of them succeeded).
The 'ident' command was also changed to match the new 'add' behavior.
Closes: 728153

We do the same in the acquire system which handles the 'normal'
downloads, so do it here as well even though its unlikely anyone
will ever notice (beside testcases of course …)

- copy only configured translation files from a CD-ROM and not all
available translation files preventing new installs with d-i from
being initialized with all translations (Closes: #678227)
- handle Components in the reduction for the source.list as multi-arch CDs
otherwise create duplicated source entries (e.g. "wheezy main main")

- do not link() but rename() the cdroms.list to cdroms.list~ as a backup
to ensure that apt-cdrom can be run multiple times (Closes: #676302)

- fix regression from 0.9.3 which dumped the main configuration
_config instead of the cdrom settings (Cnf) as identified and
tested by Milan Kupcevic, thanks! (Closes: #674100)

- use Dump() to generate the configuration output

Unfortunately it's hard to do an automated integration test with cd, so we
test this method in isolation which tries to find Indexes and dropping
of duplications with DropRepeats()

done on the mirco-optimazation level, so lets fix them:
(performance) Possible inefficient checking for emptiness.
(performance) Prefer prefix ++/-- operators for non-primitive types.

Niels Thykier, thanks! (Closes: #622805)

(also in this case its probably not needed because pkgUDevCDrom is not used outside libapt itself, still its better to be on the save side)

- deal with missing FSTAB_DIR when using libudev to discover cdrom
- add experimental APT::cdrom::CdromOnly option (on by default).
When this is set to false apt-cdrom will handle any removable
deivce (like a usb-stick) as a "cdrom/dvd" source
