The code in the Tendermint repository makes heavy use of import aliasing.
This is made necessary by our extensive reuse of common base package names, and
by repetition of similar names across different subdirectories.
Unfortunately we have not been very consistent about which packages we alias in
various circumstances, and the aliases we use vary. In the spirit of the advice
in the style guide and https://github.com/golang/go/wiki/CodeReviewComments#imports,
his change makes an effort to clean up and normalize import aliasing.
This change makes no API or behavioral changes. It is a pure cleanup intended
o help make the code more readable to developers (including myself) trying to
understand what is being imported where.
Only unexported names have been modified, and the changes were generated and
applied mechanically with gofmt -r and comby, respecting the lexical and
syntactic rules of Go. Even so, I did not fix every inconsistency. Where the
changes would be too disruptive, I left it alone.
The principles I followed in this cleanup are:
- Remove aliases that restate the package name.
- Remove aliases where the base package name is unambiguous.
- Move overly-terse abbreviations from the import to the usage site.
- Fix lexical issues (remove underscores, remove capitalization).
- Fix import groupings to more closely match the style guide.
- Group blank (side-effecting) imports and ensure they are commented.
- Add aliases to multiple imports with the same base package name.
We moved some files further down in the directory structure in #6964, which
caused the relative paths to the mockery wrapper to stop working.
There does not seem to be an obvious way to get the module root as a default
environment variable, so for now I just added the extra up-slashes.
This package is not used in the tendermint repository since 31e7cdee.
Note that this is not the same package as rpc/client/mock (N.B. singular) which
is still used in some tests.
A search of GitHub turns up only 11 uses, all of which are in clones of the
tendermint repo at old commits..
* rpc: Strip down the base RPC client interface.
Prior to this change, the RPC client interface requires implementing the entire
Service interface, but most of the methods of Service are not needed by the
concrete clients. Dissociate the Client interface from the Service interface.
- Extract only those methods of Service that are necessary to make the existing
clients work.
- Update the clients to combine Start/Onstart and Stop/OnStop. This does not
change what the clients do to start or stop. Only the websocket clients make
use of this functionality anyway.
The websocket implementation uses some plumbing from the BaseService helper.
We should be able to excising that entirely, but the current interface
dependencies among the clients would require a much larger change, and one
that leaks into other (non-RPC) packages.
As a less-invasive intermediate step, preserve the existing client behaviour
(and tests) by extracting the necessary subset of the BaseService
functionality to an analogous RunState helper for clients. I plan to obsolete
that type in a future PR, but for now this makes a useful waypoint.

## Description
- Add deprecated to config values in toml
- update config in configuration doc
- explain how to set up a node with the new network
- add sentence about not needing to fork tendermint for built-in tutorial
- closes#6865
- add note to use a released version of tendermint with the tutorials. This is to avoid unknown issues prior to a release.
If the e2e tests error, they leave all of the e2e state around including containers and networks etc.
We should clean this up when the tests shuts down, even if it exits in error.
This should address last night's failure. We've taken the perspective
of "the load generator shouldn't cause tests to fail" in recent
days/weeks, and I think this is just a next step along that line. The
e2e tests shouldn't test performance.
I included some comments indicating the ways that this isn't ideal (it
is perhaps not), and I think that if test networks could make
assertions about the required rate, that might be a cool future
improvement (and good, perhaps, for system benchmarking.)
This document attempts to capture and discuss some of the areas of Tendermint that seem to be cited as causing performance issue. I'm hoping to continue to gather feedback and input on this document to better understand what issues Tendermint performance may cause for our users.
The overall goal of this document is to allow the maintainers and community to get a better sense of these issues and to be more capably able to discuss them and weight trade-offs about any proposed performance-focused changes. This document does not aim to propose any performance improvements. It does suggest useful places for benchmarks and places where additional metrics would be useful for diagnosing and further understanding Tendermint performance.
Please comment with areas where my reasoning seems off or with additional areas that Tendermint performance may be causing user pain.
I think the `Sync` check covers our primary use case, and perhaps we
can turn this back on in the future after some kind of event-system
rewrite, or RPC rewrite that will avoid the serverside timeout.
These are mostly the timeouts that I think we're still hitting in CI.
At this point, the tests (on master) pass on my local machine (which is quite beefy) so I think this is just the first in (perhaps?) a sequence of changes that attempt to change timeouts and load patterns so that the tests pass in CI more reliably.
Communication in Tendermint among consensus nodes, applications, and operator
tools all use different message formats and transport mechanisms. In some
cases there are multiple options. Having all these options complicates both the
code and the developer experience, and hides bugs. To support a more robust,
trustworthy, and usable system, we should document which communication paths
are essential, which could be removed or reduced in scope, and what we can
improve for the most important use cases.
This document proposes a variety of possible improvements of varying size and
scope. Specific design proposals should get their own documentation.
The previous implemention of hybrid set testing, which was entirely my
own creation, was a bit peculiar, and I think this probably clears thins up.
The previous implementation had far fewer legacy nodes in hybrid
networks, *and* also for some reason that I can't quite explain,
caused a test case to fail.

The responses from node RPCs encode hash values as hexadecimal strings. This
behaviour is stipulated in our OpenAPI documentation. In some cases, however,
hashes received as JSON parameters were being decoded as byte buffers, as is
the convention for JSON.
This resulted in the confusing situation that a hash reported by one request
(e.g., broadcast_tx_commit) could not be passed as a parameter to another
(e.g., tx) via JSON, without translating the hex-encoded output hash into the
base64 encoding used by JSON for opaque bytes.
Fixes#6802.
The 0.35 release cycle renamed the 'fastsync' functionality to 'blocksync'. This change brings the configuration parameters in line with that change. Namely, it updates the configuration file `[fastsync]` field to be `[blocksync]` and changes the command line flag and config file parameters `--fast-sync` and `fast-sync` to `--enable-block-sync` and `enable-block-sync` respectively.
Error messages were added to help users encountering these changes be able to quickly make the needed update to their files/scripts.
When using the old command line argument for fast-sync, the following is printed
```
./build/tendermint start --proxy-app=kvstore --consensus.create-empty-blocks=false --fast-sync=false
ERROR: invalid argument "false" for "--fast-sync" flag: --fast-sync has been deprecated, please use --enable-block-sync
```
When using one of the old config file parameters, the following is printed:
```
./build/tendermint start --proxy-app=kvstore --consensus.create-empty-blocks=false
ERROR: error in config file: a configuration parameter named 'fast-sync' was found in the configuration file. The 'fast-sync' parameter has been renamed to 'enable-block-sync', please update the 'fast-sync' field in your configuration file to 'enable-block-sync'
```
