This modifies the goclean.sh script to run tests with the
race detector enabled. It also enables code coverage, and
uploads the results to coveralls.io.
Running tests with -race and -cover flags was disabled in
6487ba1 and 6788df7 respectively, due to some limits on
time/goroutines being hit on Travis CI. Since we have
migrated to GitHub Actions, it is desirable to bring them
back.
In this commit, we add the new release script that will be used to build
all release binaries going forward. We also remove the existing
Conformal key as it's no longer in use, updating the README to reflect
the new release build/verification process.
This updates the README to remove the mailing lists which no longer
exist and to link the GPG public key used to sign the release tags
directly from the repository instead of the no longer active website.
The github markdown interpreter has been changed such that it no longer
allows spaces in between the brackets and parenthesis of links and now
requires a newline in between anchors and other formatting. This
updates all of the markdown files accordingly.
While here, it also corrects a couple of inconsistencies in some of the
README.md files.
This adds a full-blown testing infrastructure in order to test consensus
validation rules. It is built around the idea of dynamically generating
full blocks that target specific rules linked together to form a block
chain. In order to properly test the rules, each test instance starts
with a valid block that is then modified in the specific way needed to
test a specific rule.
Blocks which exercise following rules have been added for this initial
version. These tests were largely ported from the original Java-based
'official' block acceptance tests as well as some additional tests
available in the Core python port. It is expected that further tests
can be added over time as consensus rules change.
* Enough valid blocks to have a stable base of mature coinbases to spend
for futher tests
* Basic forking and chain reorganization
* Double spends on forks
* Too much proof-of-work coinbase (extending main chain, in block that
forces a reorg, and in a valid fork)
* Max and too many signature operations via various combinations of
OP_CHECKSIG, OP_MULTISIG, OP_CHECKSIGVERIFY, and OP_MULTISIGVERIFY
* Too many and max signature operations with offending sigop after
invalid data push
* Max and too many signature operations via pay-to-script-hash redeem
scripts
* Attempt to spend tx created on a different fork
* Attempt to spend immature coinbase (on main chain and fork)
* Max size block and block that exceeds the max size
* Children of rejected blocks are either orphans or rejected
* Coinbase script too small and too large
* Max length coinbase script
* Attempt to spend tx in blocks that failed to connect
* Valid non-coinbase tx in place of coinbase
* Block with no transactions
* Invalid proof-of-work
* Block with a timestamp too far in the future
* Invalid merkle root
* Invalid proof-of-work limit (bits header field)
* Negative proof-of-work limit (bits header field)
* Two coinbase transactions
* Duplicate transactions
* Spend from transaction that does not exist
* Timestamp exactly at and one second after the median time
* Blocks with same hash via merkle root tricks
* Spend from transaction index that is out of range
* Transaction that spends more that its inputs provide
* Transaction with same hash as an existing tx that has not been
fully spent (BIP0030)
* Non-final coinbase and non-coinbase txns
* Max size block with canonical encoding which exceeds max size with
non-canonical encoding
* Spend from transaction earlier in same block
* Spend from transaction later in same block
* Double spend transaction from earlier in same block
* Coinbase that pays more than subsidy + fees
* Coinbase that includes subsidy + fees
* Invalid opcode in dead execution path
* Reorganization of txns with OP_RETURN outputs
* Spend of an OP_RETURN output
* Transaction with multiple OP_RETURN outputs
* Large max-sized block reorganization test (disabled by default since
it takes a long time and a lot of memory to run)
Finally, the README.md files in the main and docs directories have been
updated to reflect the use of the new testing framework.
This converts the project to allow btcd to be used with the glide
package manager in order to provide stable and reproducible builds
without the user having to jump through all of the hoops as they do
today.
It consists of adding a glide.yaml file which identifies the project
dependencies and locations along with a glide.lock file which contains
the complete dependency tree pinned to specific versions. Glide uses
these files to download the packages (or updates) to a local vendor
directory and checkout the correct pinned versions. The go tool, in
turn, is used to build/install btcd and will use the pinned versions in
the vendor directory.
This also updates TravisCI to build using glide, removes some of the
exceptions in the lint checks which are no longer required, and updates
the README.md with the new instructions needed to build the project with
glide.
This commit updates the main README.md and docs/README.md files to
replace the references to the now dead btcgui project with the
Windows-only Paymetheus project.
While here, it also updates some information to make it more current and
accurately describe the current status.
Now that Go 1.6 has been released, update the required Go version in the
README to 1.5 and add Go 1.6 to the configurations tested by TravisCI.
Also, while here, update the Go 1.4 and 1.5 versions tested by TravisCI
to the latest point releases.
This commit adds an additional step to the README.md install section to
run the go version command and check the version so people that are
installing it for the first time and ensure they are running a high
enough version and have GOROOT and GOPATH set correctly.
This commit updates the install command under the Installation section in
README.md to include all subdirectories thereby including the utilities
such as addblock and btcctl.
It was pointed out in #76 that if you arrived to the Update section
of the README without seeing the Installation section, the requirement for
Go 1.2 is easy to miss. This commit builds the requirement in the
Installation section and adds it to the Updating section as well to
hopefully make it more noticable.
This commit modifies btcd to run cleanly as a Windows service. btcd is
intended to be a long running process that stays synchronized with the
bitcoin block chain and provides chain services to multiple users. It
follows that a service is the best option on Windows for this
functionality.
A few key points are:
- Supports graceful shutdown via the service stop/shutdown commands
- Integrates cleanly with the Windows event log
- Adds a new /s flag that can be used to install/remove/start/stop the
service
One outstanding issue is that the application data directory is currently
user specific which means, by default, if you start btcd as a user, the
same data won't be used as when it's running as a service. This needs to
be resovled. The most likely approach will be to put all data into the
common appdata directory Windows provides, but it will require some
additional work to deal with permissions properly as user processes can't
write there by default.
Closes#42.
This commit is a rather large one which implements transaction pool and
relay according to the protocol rules of the reference implementation.
It makes use of btcchain to ensure the transactions are valid for the
block chain and includes several stricter checks which determine if they
are "standard" or not before admitting them into the pool and relaying
them.
There are still a few TODOs around the more strict rules which determine
which transactions are willing to be mined, but the core checks which
are imperative (everything except the all of the "standard" checks really)
to operate as a good citizen on the bitcoin network are in place.
