The old way of handling this was that pkgAcqMetaIndex was responsible
to check/move both Release and Release.gpg in place. This breaks
the assumption of the transaction that each pkgAcquire::Item has
a single File that its responsible for.

pkgAcq{DiffIndex,IndexMerge,pkgAcqBaseIndex, pkgAcqIndex}
|
|
If one of the pkgAcqIndex{,Merge}Diffs fails, they will run
pkgAcqIndex() which needs the IndexTarget/indexRecords data.
So we pass it along.

Beside being another big API break with hopefully zero fallout in
reality it avoids having the same member and helper code in each and
every subclass.

It is not very extensible to have the supported Hashes hardcoded
everywhere and especially if it is part of virtual method names.
It is also possible that a method does not support the 'best' hash
(yet), so we might end up not being able to verify a file even though we
have a common subset of supported hashes. And those are just two of the
cases in which it is handy to have a more dynamic selection.
The downside is that this is a MAJOR API break, but the HashStringList
has a string constructor for compatibility, so with a bit of luck the
few frontends playing with the acquire system directly are okay.

used to create a proper pkgAcqIndex() with size information
|
|
for both items and bytes
|
|
progress information
|
|
|
|
Beside being a bit cleaner it hopefully also resolves oddball problems
I have with high levels of parallel jobs.

The idea of pdiffs is to avoid downloading the hole file by patching the
existing index. This works very well, but becomes slow if a lot of
patches needs to be applied to reconstruct an up-to-date index and in
recent years more and more dinstall (or similar) runs are executed
creating more and more pdiffs in the same amount of time, so pdiffs
became less useful.
The solution is simple: Reduce the amount of patches (which are very
small) which need to be applied on top of the index we have available
(which is usually pretty big).
This can be done in two ways: Either merge the patches on the
server-side so that the client has to download only one patch or the
patches are all downloaded and merged on the client-side.
The first needs a client who is doing one step at a time who can also
skip patches if it needs (APT supports this for a long time now).
The later is implemented by this commit, but depends on the server NOT
merging the patches and the patches being in a strict order in which no
patch is skipped.
This is traditionally the case for dak, but other repository creators
support merging – e.g. reprepro (which helpfully adds a flag indicating
that the patches are merged). To support both or even mixes a client
needs more information which isn't available for now.
This POC uses the external diffindex-rred included in apt-file to
do the heavy lifting of merging & applying all patches in one pass,
hence to test this feature apt-file needs to be installed.

This helps ensure three things:
- each error is reported via ReportMirrorFailure
- if DestFile doesn't exist, do not attempt rename
- renames happen for every error
The last one wasn't the case for Size mismatches, which isn't nice, but
not a exploitable problem per-se as the file isn't picked up and remains
in partial/ where the following download-try will at most take it for a
partial request which fails the hashsum verification later on

The constructors of our (clear)sign-acquire-items move a pre-existent
file for error-recovery away, which gets restored or discarded later as
the acquire progresses, but --print-uris never really starts the
acquire process, so the files aren't restored (as they should).
To fix this both get a destructor which checks for signs of acquire
doing anything and if it hasn't the file is restored.
Note that these virtual destructors theoretically break the API, but
only with classes extending the sign-acquire-items and nobody does this,
as it would be insane for library users to fiddle with Acquire
internals – and these classes are internals.

The breakage is just to big for now, so guard the change with
#ifndef APT_8_CLEANER_HEADERS and be nice to library users

- fix fetching language information by adding OptionalSubIndexTarget
|
|
- do not check for a "Package" tag in optional index targets
like the translations index
|
|
- cleanup around OptionalIndexTarget and SubIndexTarget
|
|
- try even harder to support really big files in the fetcher by
converting (hopefully) everything to 'long long' (Closes: #632271)
|
|
mirror methods does not retry on each mirror
|
|
|
|
* apt-pkg/aptconfiguration.cc:
- remove the inbuilt Translation files whitelist
|
|
- add a special uncompressed compression type to prefer those files
* methods/{gzip,bzip}.cc:
- print a good error message if FileSize() is zero
|
|
* apt-pkg/deb/deblistparser.cc:
- rewrite LoadReleaseInfo to cope with clearsigned Releasefiles
|
|
- operate optional on gzip compressed pdiffs
* apt-pkg/acquire-item.cc:
- don't uncompress downloaded pdiff files before feeding it to rred
|

- on gpg verification failure warn and restore the last known
good state
- on failure display the IP of the server (useful for servers
that use round robin DNS)
- support Original-Maintainer in RewritePackageOrder
- enable cdrom autodetection via libudev by default
- show messsage about Vcs in use when apt-get source is run for
packages maintained in a Vcs
- better support transitional packages with mark auto-installed.
when the transitional package is in "oldlibs" the new package
is not marked auto installed (same is true for section
metapackages)
- provide new "deb mirror://archive.foo/mirrors.list sid main"
method expects a list of mirrors (generated on the server e.g.
via geoip) and will use that, including cycle on failure
- write apport crash file on package failure (disabled by default
on debian until apport is available)
- support mirror failure reporting (disabled by default on debian)
|
|
- switch {,Install-}Size to unsigned long long
* apt-pkg/depcache.cc:
- deal with long long, not with int to remove 2GB Limit (LP: #250909)
|
|
of this item is ok and does not need to be tried on all mirrors
|
|
- add a class WeakPointable which allows one to register weak pointers to
an object which will be set to NULL when the object is deallocated.
* [ABI break] apt-pkg/acquire{-worker,-item,}.h:
- subclass pkgAcquire::{Worker,Item,ItemDesc} from WeakPointable.
|
|
|
|
- add "IsIndexFile" to constructor of pkgAcqFile so that it sends
the right cache control headers

acquire-items choose which compression file they should (try first to)
download to easily add new or change the order of the compression types.
And because it is easy now we directly add builtin lzma support.
The compression ratio is better than bzip2 but we prefer the later for now
as no (official) mirror uses lzma, so this would only generate useless
hits on the servers. Maybe sometime in the future lzma will be the default...
[apt-pkg/acquire-item.cc]
- use configsettings for dynamic compression type use and order.
Based on a patch by Jyrki Muukkonen, thanks! (LP: #71746)
[apt-pkg/init.cc]
- add default configuration for compression types and add lzma
support. Order is now bzip2, lzma, gzip, none (Closes: #510526)
[ftparchive/writer.cc]
- add lzma support also here, patch for this (and inspiration for
the one above) by Robert Millan, thanks!
