- Use Ivy for resolving external dependencies rather than relying
on files found in Debian stable packages. Requires installing Ivy
(using
apt-get install ivy,brew install ivy, or similar) and runningant resolve(orant -lib /usr/share/java resolve). Retrieved files are then copied to thelib/directory, except for dependencies on other metrics libraries that still need to be copied to thelib/directory manually. Current dependency versions resolved by Ivy are the same as in Debian stretch with few exceptions. - Remove Cobertura from the build process.
- Add new SnowflakeStats descriptor type.

-
Medium changes
- Go back to using Apache Commons Codec as base64 and hexadecimal codec rather than using JAXB which won't be available anymore after upgrading from Java 8 to 9. Applications must provide Apache Commons Codec 1.10 as dependency.
-
Minor changes
- Make DescriptorCollector resume previously aborted downloads.
- Medium changes
- Replace Gson with Jackson. Applications must provide Jackson 2.8.6 or compatible as dependency and do not need to provide Gson as dependency anymore.
-
Medium changes
- Replace ServerDescriptor#getHiddenServiceDirVersions with ServerDescriptor#isHiddenServiceDir, because Tor has never supported versions in the hidden-service-dir descriptor line.
- Add support for reading web server logs contained in tarballs by providing file names of both the tarball and of contained files to WebServerAccessLog.
-
Minor changes
- Override logLines() method from LogDescriptor in WebServerAccessLog.
- Use 1-minute connect and read timeouts for fetching CollecTor's index.json.

-
Minor changes
- Replace custom ImplementationNotAccessibleException thrown by DescriptorSourceFactory with generic RuntimeException.
- Rename jar files and release tarball to start with "metrics-lib".
-
Major changes
- Simplify DescriptorReader by returning Descriptor instances rather than DescriptorFile instances containing Descriptors, deprecate DescriptorFile, and add a File reference to Descriptor.
- Introduce a new UnparseableDescriptor to be returned by DescriptorParser and DescriptorReader if a descriptor cannot be parsed, as opposed to throwing a DescriptorParseException or skipping the entire descriptor file, respectively.
-
Medium changes
- Let DescriptorParser return an Iterable instead of a List, which prepares parsing large descriptor files descriptor by descriptor.
- Add new method to retrieve the raw descriptor length, rather than forcing applications to request (a copy of) raw descriptor bytes only to determine the raw descriptor length.
-
Minor changes
- Fix a bug where NetworkStatusEntry's getMicrodescriptorDigests() and getMicrodescriptorDigestsSha256Base64() return hex strings rather than base64 strings.
- Medium changes
- Fix a regression where any DescriptorParseException thrown while parsing a descriptor is encapsulated and rethrown as RuntimeException.
- Medium changes
- Fix a regression in parsing microdescriptors and version 1 directories introduced in 1.8.0.
-
Medium changes
- Store raw descriptor contents as offset and length into a referenced byte[], rather than copying contents into a separate byte[] per descriptor.
-
Minor changes
- Turn keyword strings into enums and use the appropriate enum sets and maps to avoid repeating string literals and to use more speedy collection types.
- Simplify and avoid repetition in parse helper methods.
- Fix a bug where Microdescriptor's getDigestSha256Base64() returns a hex string rather than a base64 string.
- Move descriptor digest computation to DescriptorImpl.
- Fix a bug in digest computation by making sure that the descriptor string actually contains the end token.
- Fix a bug where both RelayDirectoryImpl and all NetworkStatusImpl subclasses fail to get indexes right if parts of raw descriptor strings contain non-ASCII chars. In practice, this only affects version 1 directories which were last archived in 2007.
-
Medium changes

- Add support for six new key-value pairs added by OnionPerf.
- Fix a bug where DescriptorIndexCollector would not delete extraneous local files if remote paths start with /.
- Add previously missing method to obtain the digest of a vote.
- Deprecate setFailUnrecognizedDescriptorLines() in DescriptorParser and DescriptorReader and refer to getUnrecognizedLines() in Descriptor if applications really need to fail descriptors containing unrecognized lines.
- Parse "padding-counts" lines in extra-info descriptors.
-
Minor changes
- Accept extra arguments in statistics-related extra-info descriptor lines, as permitted by dir-spec.txt.
- Streamline digest method names.
-
Major changes
- Deprecate DescriptorDownloader in favor of the much more widely used DescriptorCollector.
-
Medium changes
- Add two methods for loading and saving a parse history file in the descriptor reader to avoid situations where applications fail after all descriptors are read but before they are all processed.
- Unify the build process by adding git-submodule metrics-base in src/build and removing all centralized parts of the build process.
- Avoid deleting extraneous local descriptor files when collecting descriptors from CollecTor.
- Turn the descriptor reader thread into a daemon thread, so that the application can decide at any time to stop consuming descriptors without having to worry about the reader thread not being done.
- Parse "proto" lines in server descriptors, "pr" lines in status entries, and "(recommended|required)-(client|relay)-protocols" lines in consensuses and votes.
- Parse "shared-rand-.*" lines in consensuses and votes.
- Deprecate DescriptorCollectorImpl now that DescriptorIndexCollector is the default.
-
Major changes
- Make the DescriptorCollector implementation that uses CollecTor's index.json file to determine which descriptor files to fetch the new default. Applications must provide gson-2.2.4.jar or higher as dependency.
-
Minor changes
- Avoid running into an IOException and logging a warning for it.
-
Major changes
- Add the Simple Logging Facade for Java (slf4j) for logging support rather than printing warnings to stderr. Applications must provide slf4j-api-1.7.7.jar or higher as dependency and can optionally provide a compatible logging framework of their choice (java.util.logging, logback, log4j).
-
Medium changes
- Add an alpha version of a DescriptorCollector implementation that is not enabled by default and that uses CollecTor's index.json file to determine which descriptor files to fetch. Applications can enable this implementation by providing gson-2.2.4.jar or higher as dependency and setting property descriptor.collector to org.torproject.descriptor.index.DescriptorIndexCollector.
-
Minor changes
- Include resource files in src/*/resources/ in the release tarball.
- Move executable, source, and javadoc jar to generated/dist/.
- Medium changes
- Adapt to CollecTor's new date format to make DescriptorCollector work again.
-
Medium changes
- Parse "package" lines in consensuses and votes.
- Support more than one "directory-signature" line in a vote, which may become relevant when authorities start signing votes using more than one algorithm.
- Provide directory signatures in consensuses and votes in a list rather than a map to support multiple signatures made using the same identity key digest but different algorithms.
- Be more lenient about digest lengths in directory signatures which may be longer or shorter than 20 bytes.
- Parse "tunnelled-dir-server" lines in server descriptors.
-
Minor changes
- Stop reporting "-----END .*-----" lines in v2 network statuses as unrecognized.
-
Medium changes
- Include the hostname in directory source entries of consensuses and votes.
- Also accept \r\n as newline in Torperf results files.
- Make unrecognized keys of Torperf results available together with the corresponding values, rather than just the whole line.
- In Torperf results, recognize all percentiles of expected bytes read for 0 <= x <= 100 rather than just x = { 10, 20, ..., 90 }.
- Rename properties for overriding default descriptor source implementation classes.
- Actually return the signing key digest in network status votes.
- Parse crypto parts in network status votes.
- Document all public parts in org.torproject.descriptor and add an Ant target to generate Javadocs.
-
Minor changes
- Include a Torperf results line with more than one unrecognized key only once in the unrecognized lines.
- Make "consensus-methods" line optional in network statuses votes, which would mean that only method 1 is supported.
- Stop reporting "-----END .*-----" lines in directory key certificates as unrecognized.
- Add code used for benchmarking.
-
Medium changes
- Parse flag thresholds in bridge network statuses, and parse the "ignoring-advertised-bws" flag threshold in relay network status votes.
- Support parsing of .xz-compressed tarballs using Apache Commons Compress and XZ for Java. Applications only need to add XZ for Java as dependency if they want to parse .xz-compressed tarballs.
- Introduce a new ExitList.Entry type for exit list entries instead of the ExitListEntry type which is now deprecated. The main difference between the two is that ExitList.Entry can hold more than one exit address and scan time which were previously parsed as multiple ExitListEntry instances.
- Introduce four new types to distinguish between relay and bridge descriptors: RelayServerDescriptor, RelayExtraInfoDescriptor, BridgeServerDescriptor, and BridgeExtraInfoDescriptor. The existing types, ServerDescriptor and ExtraInfoDescriptor, are still usable and will not be deprecated, because applications may not care whether a relay or a bridge published a descriptor.
- Support Ed25519 certificates, Ed25519 master keys, SHA-256 digests, and Ed25519 signatures thereof in server descriptors and extra-info descriptors, and support Ed25519 master keys in votes.
- Include RSA-1024 signatures of SHA-1 digests of extra-info descriptors, which were parsed and discarded before.
- Support hidden-service statistics in extra-info descriptors.
- Support onion-key and ntor-onion-key cross certificates in server descriptors.
-
Minor changes
- Start using Java 7 features like the diamond operator and switch on String, and use StringBuilder correctly in many places.
- Major changes
- This is the initial release after four years of development. Happy 4th birthday!
