For cases like the OpenVPN vuln that was recently announced, it is useful
for fdroiddata maintainers to be able to mark builds that have known
vulnerabilities.
The new policy is to move APKs with invalid signatures to the archive,
and only add those APKs to the archive's index if they have valid MD5
signatures.

The original logic was checking keepversions against the len() of ALL the
APKs in the repo/archive. The correct thing is to check against the
number of APKs available for the given packageName/appid.

`fdroid update` crashed for apps that only had screenshots but no graphics
or localized texts because destdir was not being set in that case. This
fixes that and adds a test case.
closes#320!286
If working with a random grabbag of APKs, there can be all sorts of
issues like corrupt entries in the ZIP, bad signatures, signatures that
are invalid since they use MD5, etc. Moving these two checks later means
that the APKs can be renamed still.
This does change how common.getsig() works. For years, it returned
None if the signature check failed. Now that I've started working
with giant APK collections gathered from the wild, I can see that
`fdroid update` needs to be able to first index what's there, then
make decisions based on that information. So that means separating
the getsig() fingerprint fetching from the APK signature verification.
This is not hugely security sensitive, since the APKs still have to
get past the Android checks, e.g. update signature checks. Plus the
APK hash is already included in the signed index.
With a generic file, the file name is the only guaranteed name metadata
field. So if the name is not specified in the metadata, then the name
is set to the filename. This changes that so that the file extension is
stripped from that generated name.
This is useful for parsing APK files, which can include packageName,
versionCode, and optionally 7 char signing key ID (i.e. <sig>).
This also can set the packageName and versionCoe for non APK files, so
that it is easy to assign them to metadata files, and to allow for
upgrades by setting the versionCode in the filename.
Really, it is the fdroidclient parser of index.xml that fails, due to the
hardcoded expectation that there will only ever be a single APK for any
given versionCode. We keep index.xml backwards compatible for old
clients, and use index-v1.json to support new things. Having multiple
APKs that have the same packageName and versionCode will break the client
v0.103.* since that version uses index-v1.json, but still has the hard-
coded database parsing stuff.
#153
uses the standard package.name_123.apk. If that exists, it appends the
shasum. If that exists, then its a duplicate, so its deleted. This should
help @SergeWinters with his 12,000 APKs.
There are many APKs out in the wild that claim to be the same app and
version and each other, but they are signed by different keys. fdroid
should be able to index these, and work with them. This supports having
the developer's signature via reproducible builds, random collections of
APKs like repomaker, etc.
This is some very messy logic built up since 2010. This will all go away
once we have a python3 version of androguard available.
The removed imports and `dir(APK)` is to silence pyflakes

This is a little omission. keys that are used in metadata/*.yml all start
with an UpperCase letter, but in fdroidserver, index-v1.json, and
fdroidclient, it is all camelCase with lowercase first letter. The keys
from the 'localized' section are currently never in metadata/*.yml, so
these keys never get downcase. This change will break fdroidclient
versions that do not also have this change, but since we're in alpha, that
should be fine.
If support for a 'localized' section is added to metadata/*.yml, then the
keys there should probably be UpperCase CamelCase to match the other keys.
Fastlane Supply, Triple-T Gradle Play Publisher, and many app stores
include the possibility to specify a website for the author, as distinct
from the website for the app.
closes#204
This uses the "What's New" entry for the CurrentVersionCode and includes it
as the current WhatsNew metadata for the App class.
Things like fastlane supply and Google Play support a "What's New" entry
per-APK, but fdroidclient does not current use anything but the current
version of this data. Right now, it seems we probably only want to have
the latest WhatsNew in the index to save space.
In theory, we could make the WhatsNew data structure follow the structure
of fastlane/Play, but that would quite a bit of complexity for something
that might never be used.

This option was not hooked up at all, and does not make sense as a command
line argument. It should just be a config.py item. In that case, the
presence of config.py marks the current dir as a repo, so there is no
longer a need to test for a dir called repo/ as a safety. This makes the
setup easier, since sync_from_localcopy() now creates repo/ for the user.
Since `fdroid server update` is the place where all uploads to servers
happens, it makes sense to also handle the git push for the binary
transparency log here instead of `fdroid btlog`
Google has their own utility for verifying APK signatures on a desktop
machine since Java's jarsigner is bad for the task. For example, it
acts as if an unsigned APK validates. And to check whether an APK is
unsigned using jarsigner is difficult.
apksigner also does the v2 signatures, so it will have to be used
eventually anyway. It is already in Debian/stretch and can be
available in jessie-backports if need be.

The ZIP format allows multiple entries with the exact same filename, and on
top of that, it does not allow deleting or updating entries. To make the
`fdroid verify` procedure failsafe, it needs to create a new temporary APK
that is made up on the contents of the "unsigned APK" and the signature
from the "signed APK". Since it would be possible to give a signed APK as
in the unsigned one's position, `fdroid verify` was not able to update the
signature since it was just adding the new signature to the end of the ZIP
file. When reading a ZIP, the first entry is used.
