These entries are hardcoded as a single line in all the app stores, so
newlines should be stripped to get the data simple to use. This is in
contrast with the on-disk format for Fastlane and Triple-T, which includes
a newline in the title.txt and short_description.txt files. I think all
files in those systems are normalized to end in a newline.
Python PIL is not so tolerant, so bad EXIF causes crashes:

Using a filename based on the hash of the contents means that the caching
algorithms for fdroidclient and browsers can safely cache the file forever
using the filename, since this guarantees that the contents will never
change for a given filename.
This does not cover screenshots, only icon.png, featureGraphic.png,
tvBanner.png, and promoGraphic.png.

This was done with much help from @uniqx. This is the first level of
supporting APK Signatures v1, v2, and v3. This is enough to include
APKs with any combo of v1/v2/v3 signatures. For this to work at all,
apksigner and androguard 3.3.3+ must be installed.

699b3e4c69 got it wrong for targetSdkVersion.
Also, one confusing thing is that aapt outputs "sdkVersion: '3'" for
com.politedroid_3.apk but no "sdkVersion:" for no.min.target.sdk_987.apk.
F-Droid never really supported running on android-1 or android-2, so it
seems pointless to debug support for them.
pickle can serialize executable code, while JSON is only ever pure data.
The APK cache is only ever pure data, so no need for the security risks of
pickle. For example, if some malicious thing gets write access on the
`fdroid update` machine, it can write out a custom tmp/apkcache which would
then be executed. That is not possible with JSON.
This does just ignore any existing cache and rebuilds from scratch. That is
so we don't need to maintain pickle anywhere, and to ensure there are no
glitches from a conversion from pickle to JSON.

An APK (Netflix) was found to have the following icon filename:
\u2003\u2009\n.xml
This breaks the aapt dump parsing because it iterates line by line and
this filename goes across two lines. Consequently, icon_src will be
None (default value) when it is passed to the icons parser.
There is a hardcoded template in update.py, and there is also the
possibility for the user to create a template.yml. This tests both of them
and cleans up the related code a bit.
#352!310
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.

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.
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 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.
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.
