A recent revision of the Ethereum white paper removes the denominations
labeled 'lovelace', 'babbage' and 'shannon' [1]. This commit reflects
the change to the whitepaper by removing the corresponding labels from
the Denomination enum (as an aside, note the discrepancy between
'lovelace' in the whitepaper and 'ada' in our implementation).
go-ethereum still contains these values, but cpp-ethereum does
not. This commit assumes that the whitepaper and cpp implementation
represent the current consensus on explicitly named denominations.
By the same rationale, the 'douglas' and 'einstein' labels have been
removed as well. These values never appeared in the whitepaper or cpp
implementations. They were introduced to the go implementation in
ethereum/go-ethereum@e7d9bcd, but because the whitepaper and cpp
implementation are silent on these values, they are omitted here.

- Replace leading tabs with spaces
- Add space before opening curly brace
- Optimize imports using shared .idea/codeStyleSettings.xml
- Do not align assignments on equals sign
- Remove unnecessary extra newlines
Running `gradle build` within ethereumj-core will now produce -sources
and -javadoc jars in `build/libs`, alongside the already existing
classes jar. Run `gradle install` to install these artifacts to the
local `~/.m2` repository.
This change ensures that all Javadoc syntax, reference, html errors, etc
are reported at the commandline during the gradle build, but warnings
for missing Javadoc elements (e.g. no @return tag, @param tags, etc) are
suppressed. `man javadoc` for details.
Add .idea/codeStyleSettings.xml with explicit settings for each
2nd-level package used within ethereumj, adding a separator between
each (unfortunately there is no other way to gain this level of control
in IDEA).
Imports are generally in alphabetical order, with two key exceptions:
- org.ethereumj.* imports are always sorted at top, to simplify the
process of seeing how one ethereumj type relates to all others. This is
especially useful in the practice of avoiding cyclic package
dependencies.
- java.* and javax.* and sun.* imports are always sorted at bottom.
Wildcard imports are used for static imports whenever two or more
members of the same type are statically imported, but wildcards are
never used for non-static imports. This policy of explicitness helps
identify classes that are too "fat", i.e. have too many dependencies on
other types.
The root .gitignore file has been updated to allow
.idea/codeStyleSettings.xml, so as to automatically share it with other
team members. Any changes made to import organization settings will be
reflected in this file and should be checked in.
See updated ethereumj-studio/README.md for details. Note that this
commit removes the `build-post-package.xml` ant file (for now) to
simplify the Gradle arrangement. This functionality can be re-introduced
later and more simply using Gradle's native DSL. In the meantime, both
the -core and -studio projects can be run using `gradle run` or run as
executable jars by running `gradle shadowJar` followed by the usual
`java -jar` execution of the resulting `-all` jar file found in each
project's respective `build/libs` directory.
- Convert ethereumj-studio build from Maven to Gradle as well
- Extract common build elements to top-level build.gradle
- Update top-level README accordingly
Block#getMinGasPrice and Blockchain#getGasPrice were removed in commit
aad53ba, causing compilation failures in ethereumj-studio when building
against current master of ethereumj-core. As it is unclear whether these
methods have proper replacements, this commit simply replaces calls to
these now-missing methods with the value `42`. Obviously this is a
stopgap measure and should be addressed properly as soon as possible.
The tests ignored in this commit have been failing for some time--both
under the Maven build and now under the new Gradle build. See
https://travis-ci.org/ethereum/ethereumj/builds/45100679 for an example
CI build that reflects these failures.
Rather than tracking down and fixing each issue, this commit ignores
each of these known failures such that subsequent refactorings and
changes can be made with the benifit of running the tests that do work
and knowing that no new failures have crept in.
Apply Gradle's 'maven' plugin in order to support `./gradlew install`
task, similar to `mvn install` for building and copying artifacts to the
users local ~/.m2 repository.
After porting the build from Maven to Gradle (see prior commits), the
org.ethereum.serpent.ParserGenerator class is no longer necessary as the
configuration of the antlr compiler that happened in this class now
happens directly in build.gradle. This class is thus removed in this
commit.
The plexus FileUtils class introduced by the antlr4 Maven plugin had
also been used in several locations in the codebase, probably just for
reasons of convenience. These uses have been replaced with Spring's
FileSystemUtils in order to allow for dropping the dependency on the
antlr4 Maven plugin entirely.
ethereumj-core depends on elements specific to the JUnit 4.11 API, but (for
reasons that can only be assumed dubious) json-simple:1.1.1 transitively
includes JUnit 4.10. At the command line, Gradle handles this cleanly,
and gives ethereumj-core's direct dependence on 4.11 the precedence it
deserves. However, IDEA gets confused and gives 4.10 precedence. This
change explicitly excludes the transitive dependency from
json-simple->junit:4.10, eliminating the issue completely.
Previously, sources generated from the serpent antlr grammar in
ethereumj-core/src/main/antlr4 were output into the build/generated-src
directory by default. This worked from the command line without issue,
but caused issues within IDEA, because the entirety of the 'build'
directory is excluded from compilation by default when working with a
Gradle-based project in IDEA.
This change simplifies the arrangement by writing these antlr-generated
sources to the src/gen/java. A .gitignore file has been added to ensure
that transient source files don't accidentally get checked in. A readme
file has been added to explain the situation to the uninitiated.
Prior to this change, the affected classes had Javadoc containing a url
as the first sentence. There were several issues with this:
- The url used was inconsistent, varying between www.etherj.com,
www.ethereumj.com and www.ethergit.com
- Use of a url in the first sentence of a Javadoc comment is not
consistent with Javadoc idioms. The first sentence should be the
a short, self-contained description--in this case, the description of
the class. If no such description is yet available, it is best to
simply omit all text, leaving any tags (such as @author or @since).
- Information about the project that this code belongs to should be
expressed in the license header for each file. Currently, most files
in ethereumj do not have license headers. This can be added in a
later commit.
