This works around the gradle 2.x bug where versions newer than 2.9 cannot
run things. This also then specifies the version of Gradle Android Plugin
that is included in Debian/stretch.
This fixes all the bugs I could find that prevented fdroid from
handling files with spaces in them. This is more important now that
fdroid supports random media files, and Repomaker
This filename has some messed up bytes related to bi-directional script
that is included (Left-to-Right and Right-to-Left). GNU/Linux always
interprets filenames as pure byte sequences. Windows and OSX store
filenames as Unicode strings. So on OSX, the invalid filename gets
converted to a valid name. That works fine, but the test fails because it
is compared to a file generated on Ubuntu, where it preserves the byte
sequence.
This includes an APK with a valid Unicode filename that includes
bi-directional script.
apksigner v0.7 (build-tools 26.0.1), Google made it require that the
AndroidManifest.xml was present in the archive before it verifies the
signature. So this needs to stick with the jarsigner hack for JARs.
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
With the new localization support, the name/summary/description in the
metadata file becomes the global override. So most apps are not going to
have those fields present in their metadata file. This fixes the index.xml
generation to fall back to the localized versions of those fields when they
are not set in the metadata field.

It turns out it is error prone to `git push` to a non-bare git repo. For
the offline signing machine, the git remote needs to be a regular git repo
in a directory on a thumbdrive so that once the thumbdrive is plugged into
an online machine, that git repo can be transferred to the online machine.
Since the mirror URLs are per repo section (repo/archive), the mirror URLs
must include the repodir at the end. This was missing for servergitmirrors

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.
closes#323closes#292
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.
closes#166
`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
closes#303
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.
fdroidclient#910
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.
https://android.googlesource.com/platform/tools/apksighttps://packages.debian.org/apksigner
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.
This is a bit different than index.jar: instead of their being index.xml
and index_unsigned.jar, the presense of index-v1.json means that there is
unsigned data. That file is then stuck into a jar and signed by the
signing process. index-v1.json is never published to the repo. It is
included in the binary transparency log, if that is enabled.
This just makes it easier for people writing build recipes. Rewriting will
output a list of strings as well.
The test index.xml and categories.txt are updated to include the new number
categories, and the changed CurrentVersionCode to 2147483647 (MAX_VALUE)
This syncs up the field names between the fdroiddata .yml files, the keys
used in the implementation in fdroidserver, the index data format, and the
final data structures in fdroidclient. This makes it easier for devs to
follow, and makes the Jackson parsing library automatically handle
converting the data from the index file to Java instances.
This bumps the metadata version since the apkcache will have to be
discarded.
Here are the name changes:
* apkname --> apkName
* id --> packageName
* sha256 --> hash
* version --> versionName
* versioncode --> versionCode
tests/repo/index.xml was changed only to bump the metadata version
from 17 to 18.
Python encode/decode libs work directly with dicts, so the internal dict
can just be passed directly to any of these libs (pyyaml, pyjson, msgpack,
simplejson, etc). This still generates the exact same index.xml as before.
This converts the internal format for the repo timestamp to a datetime
instance, which can be easily converted to UNIX time in seconds for XML
and UNIX time in milliseconds for the new index formats. UNIX time in
milliseconds is directly serialized into a java.util.Date instance by
Jackson.
Since it is now possible to build and include arbitrary files, like OTA
update ZIP files, the update procedure needs to look for non-APK files that
match the packageName_versionCode pattern of fdroid-generated files.

This lets index-v1 be parsed directly into class instances because the
field/instance var names match exactly. The original index v0 element
must retain the 'lastupdated' name for backwards compatibility.
If a group of items are enclosed in {}, then that will be a Python set,
which does not preserve order. To preserve order, the data must be either
a tuple () or list [].
Since https://gitlab.com/fdroid/ci-test-app is a separate git repo, things
with incompatible changes could get out of sync. Therefore, this test
should specify which git commit is runs against.
For example, the .fdroid.yml file is still a moving target. Just now, the
keys had the spaces removed as part of this MR.
In the future, we should have better internal datatypes for this stuff,
i.e. instead of gradle: ['yes'] for True, actually use a boolean. For now,
make the YAML and JSON metadata produce the same internal data as .txt.
This requires manually running it. I suppose it would be possible to
include a snapshot of the dumped internal representation for each release,
then make the tests run automatically against that. Right now, the dump is
17megs of YAML. Seems large to include in this git repo.
Like with the App class in the commit before, this makes it a lot
easier to work with this data when converting between the internal
formats and external formats like YAML, JSON, MsgPack, protobuf, etc.
The one unfortunate thing here is Build.update. It becomes
dict.update(), which is a method not an attribute.
build.get('update') or build['update'] could be used, but that would
be oddly inconsistent. So instead the field is renamed to
'androidupdate', except for in the .txt v0 metadata files. This better
describes what field does anyway, since it runs `android update`.
Build.update is only referenced in two places right next to each other
for the ant builds, so this change still seems worthwhile.
Python is heavily based on its core data types, and dict is one of the more
important ones. Even classes are basically a wrapper around a dict. This
converts metadata.App to be a subclass of dict so it can behave like a dict
when being dumped and loaded. This makes its drastically easier to use
different data formats for build metadata and for sending data to the
client. This approach will ultimately mean we no longer have to maintain
custom parsing and dumping code.
This also means then that the YAML/JSON field names will not have spaces in
them, and they will match exactly what it used as the dict keys once the
data is parsed, as well as matching exactly the instance attribute names:
* CurrentVersion: 1.2.6
* app['CurrentVersion'] == '1.2.6'
* app.CurrentVersion == '1.2.6'

https://goodcode.io/articles/python-dict-object/
The original index.xml format needs to stay around for backwards
compatibility, but we shouldn't touch it anymore once the new format is in
place. This is a test to make sure `fdroid update` can still generate the
correct XML.
install_list and uninstall_list should be tuples or lists in order to
ensure that the order is preserved.
These tests also check that the added and lastupdated dates are
working correct, based on the dates in tests/stats/known_apks.txt. I
could see no useful way to test the timestamp, it is just hardcoded
using a regexp search-and-replace. Running these tests manually might
require deleting tmp/apkcache.
When making code changes related to the metadata parsing, it is useful to
see how the internal format has changed by seeing the differences in the
dump files. Those files are currently in the binary .pickle format. This
just straight converts them to YAML, which is a text format, so that normal
diff tools work to see changes.
The dump files are named .yaml instead of .yml since .yml is used for hand-
edited YAML files for fdroiddata/metadata, while these dump files here are
a human readable form of a Python pickle.
JSON and YAML are very closely related, so supporting both of them is
basically almost no extra work. Both are also closely related to how
Python works with dicts and pickles. XML is a very different beast, and its
not popular for this kind of thing anyway, so just purge it.
This allows a source repo to include a complete metadata file so that it
can be built directly in place using `fdroid build`. If that app is then
included in fdroiddata, it will first load the source repo type and URL
from fdroiddata, then read .fdroid.yml if it exists, then include the rest
of the metadata as specified in fdroiddata, so that fdroiddata has
precedence over the metadata in the source code.
This lets `fdroid build` apps without having a whole fdroiddata setup, but
instead just directly in place in the source code. This also lets devs
optionallu maintain the fdroid metadata as part of their app, rather than
in fdroiddata without loosing any control. This should make it easier to
spread around the maintenance load.
Something like `gradle: yes` in YAML will be parsed as a boolean, since
'yes' is officially defined as a boolean true in YAML. For metadata fields
that need to be lists, this needs to be converted. Same goes for a single
string like `gradle: customFlavor`.
This makes sure there is a GPG signature on any file that is included in
the repo, including APKs, OBB, source tarballs, media files, OTA update
ZIPs, etc. Having a GPG signature is more important on non-APK files since
they mostly do not have any signature mechanism of their own.
This also adds basic tests of adding non-APK/OBB files to a repo with
`fdroid update`.
closes#232
This makes it so that the final build product can be specified in output=
and it'll work no matter if its an APK or not. This was developed around
the case of building the OTA update.zip for the Privileged Extension. It
should work for any build process in theory but it has not yet been tested.
https://gitlab.com/fdroid/privileged-extension/issues/9
It is now possible for the server operator to specify lists of apps that
must be installed or deleted on the client (aka "push installs). If
the user has opted in, or the device is already setup to respond to
these requests, then fdroidclient will automatically install/delete
the packageNames listed. This is protected by the same signing key
as the app index metadata.
It generates single XML elements with the data set in the attributes. This
keeps the XML compact and easily extensible, e.g. for adding versionCode,
signingKey, etc as attributes:
<install packageName="com.fsck.k9"/>
<install packageName="at.bitfire.davdroid"/>
<delete packageName="com.facebook.orca"/>

`fdroid update` should be able to handle any valid filename (hopefully
aapt doesn't barf on them). To handle that, the environment where the

This also renames test APK with lots of Unicode chars as a test case.

Also, remove jdk7 as it will become unused. We added jdk8 for
retrolambda, and now that we will use jdk8 as the default, jdk7 is
unnecessary as retrolambda can work fine with just jdk8.
This removes it from the buildserver, and the new CI image also only has
jdk8 from jessie-backports.
Fixes#185.
This replaces the current default behavior of always forcing the

.java .gradle and XML files all can use any encoding. Most code is ASCII,
but authors' names, etc. can easily be non-ASCII. UTF-8 is by far the most
common file encoding. While UTF-8 is the default encoding inside the code
in Python 3, it still has to deal with the real world, so the encoding
needs to be explicitly set when reading and writing files. So this switches
fdroidserver to expect UTF-8 instead of ASCII when parsing these files. For
now, this commit means that we only support UTF-8 encoded *.java, pom.xml
or *.gradle files. Ideally, the code would detect the encoding and use the
actual one, but that's a lot more work, and its something that will not
happen often. We can cross that bridge when we come to it.
One approach, which is taken in the commit when possible, is to keep the
data as `bytes`, in which case the encoding doesn't matter.
This also fixes this crash when parsing gradle and maven files with

* .travis.yml
* .gitlab-ci.yml
* .circle.yml
* Ansible main.yml
The start up sequence of processes that are based on the .fdroid.* metadata
is a bit different, so this ensures that the environment variables get

This also creates a single function where the environment is set. Before
it was being set in multiple places across multiple files.
serverwebroot has long supported uploading to multiple servers, this bit of

This will report the version embedded in the module if it is installed, and
will report `git describe` if being run from git. If someone installs from
git using pip, this will probably report the version in setup.py, which
will be wrong. But that is not a documented install method, and I haven't
heard of anyone using it. The recommended way is to run straight from git.
For a bit repo like f-droid.org, it makes sense to standardize on a single
format for metadata files. This adds support for enforcing a single data
format, or a reduced set of data formats. So f-droid.org would run like
this if it changed to YAML:
accepted_formats = ['txt', 'yaml']
Then once everything was converted to YAML, it could look like this:
accepted_formats = ['yaml']
In order to prevent confusion caused by multiple metadata files for a given
app, fdroid will exit with an error if it finds any app metadata file with
the same package ID as one that has already been parsed.
YAML is a format that is quite similar to the .txt format, but is a
widespread standard that has editing modes in popular editors. It is also
easily parsable in python.
The .pickle for testing is a lightly edited version of the real metadata
for org.videolan.vlc:
* comments were removed
This puts all of the needed post parsing checks on the metadata into a
single method that is used by all parsing methods (.txt, JSON, XML, YAML).
This provides the single place to normalize the internal representation of
the metadata.
It would be good to also change the internal representation to use more Python
bool/int types so that less post parsing is needed for JSON, XML, and YAML.
The SMSSecure test .pickle was changed to account for the use of lstrip()
and rstrip() on all 'script' types.
This also changes the example JSON to use ints for versionCodes
While the current text metadata format is good for human readability and
editability, it is difficult to produce and parse using code. XML is a
widespread standard format for easy automatic parsing and creating, while
having decent human readability.
The .pickle for testing is a lightly edited version of the real metadata
for net.osmand.plus:
* comments were removed
* "NonFreeNet" was added as an AntiFeature
The AntiFeatures metadata is a comma-separated list of tags, like
Categories, so it should also be stored internally as a list. This makes
parsing XML and JSON easier.
The test cases' .pickle files look like they change a lot, but they really
don't, its only the change of default AntiFeatures value from None to []
The .pickle was created by dumping the output from parsing the current .txt
metadata for org.adaway. The JSON started from that pickle dump, but was
then hand edited to be more proper JSON, e.g. using boolean values.
This is a test to cover future modifications of the .txt metadata parsing.
The pickle file was generated by just dumping the current parsed metadata,
so this test will always succeed if the parsing is not changed.

Sometimes, buildToolsVersion is a kind of gradle macro call, and other
times it is a variable assignment. This regsub pattern now handles both of
those cases.
This provides the final option in this series, allowing the user to just
add --create-key to `fdroid update, and thereby upgrade an unsigned repo to
a proper signed repo. It also might be useful
closes#13https://gitlab.com/fdroid/fdroidserver/issues/13
This is a more flexible approach than testing for the complete SDK and
build-tools up front. This will only test for the commands that are
actually being run, so that if you only have `aapt` installed, you can do
`fdroid update` without errors, but other commands will still give
appropriate errors.
This also makes the build_tools item in config.py optional, it is only
needed if you want to force a specific version of the build-tools.
Just getting into the habit of adding tests to everything that I change...
Also, it should be useful to have an unsigned APK in the test collection,
since `fdroid update` should handle it gracefully and give a warning of
some kind.
The test for the help flag threw an error if there were 0 args, or if arg 1
was set to a space-separated list. The -z tests would fail if the arg was
set to a space-separated list.
This gives us flexibility in how the blocks of text can be formatted in
config.py, but also provides a more useful format for displaying since the
client can decide where to wrap the text.
This reverts b637568a62 since it added a
redundant check that broke `fdroid init` when the default version dir of
build_tools does not exist on the local system. It then uses the function
that was already in place for checking the build_tools setup in a way that
does not break `fdroid init`.
Now that the fake android home version is not matching the default version,
the tests will catch this bug in the future.
This is testing the build-tools version auto-detect in `fdroid init`, so it
should be kept as an older version. This is not meant to test the current
version of the build tools.
This means you can just do `cd tests/ && ./run-tests` to run the tests now.
You can still override the APK source with the first argument, like:
cd tests/ && ./run-tests /path/to/lots/of/apks/dir
To support a fully offline build/signing machine, there is the "local copy
dir". The repo is generated on the offline machine and then copied to a
local dir where a thumb drive or SD Card is mounted. Then on the online
machine, using `fdroid server update --sync-from-local-copy-dir` allows
the whole server update process to happen in a single command:
0. read config.py on online machine's repo
1. rsync from the local_copy_dir to the current dir
2. copy to serverwebroot, awsbucket, etc.
This allows a dir to be specified in config.py that `fdroid server update`
will automatically rsync the repo to. The idea is that the path would
point to an SD card on a fully offline machine that serves as the secure
repo signing machine.
Not everyone adds the build-tools to their PATH, so this makes it so this
script will find aapt in the most recent build-tools version that is
installed on the local system.
In this case, ANDROID_HOME is set to a fake, non-working version that will
be detected by fdroid as an Android SDK install. It should use the path
set by --android-home over the one in ANDROID_HOME, therefore if it uses
the one in ANDROID_HOME, it won't work because it is a fake one. Only
--android-home provides a working one.
This lets people easily set whatever dir they want, while letting jenkins
search through its whole workspace for any APKs that have been built. Also,
only include the latest version of a given packageName+versionCode.
Yes, this includes a binary file, but it is only for the tests, and it is
free software since I wrote it. The source is here:

Previously, `fdroid update -c` would only create the new metadata, but
would not add the new apps/apks to the repo. That required a second run of
`fdroid update`. This has been fixes, so this test makes sure it stays
fixed, in a very generic way.
Make sure that fdroid can find aapt in the current config, otherwise exit
with an error. Some users don't have build_tools set, and their SDK does
not include the build-tools in the default versioned dir, so this should
warn them of what is wrong.
This allows the user to set the path to their Android SDK from the command
line. This option is named after the standard env var ANDROID_HOME, as used
in the build.xml generated by `android update project`. --android-home
takes precendence over the ANDROID_HOME env var if it is set.
This assumes that the smartcard is already setup with a signing key. init
does not generate a key on the smartcard, and skips genkey() if things are
configured to use a smartcard.
This also does not touch APK signing because that is a much more elaborate
question, since each app is signed by its own key.
