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'
```
This is just a configuration change to default to using the new stack
unless explicitly disabled (e.g. `UseLegacy`) this renames the
configuration value and makes the configuration logic more clear.
The legacy option is good to retain as a fallback if the new stack has
issues operationally, but we should make sure that most of the time
we're using the new stack.
## Description
Expose p2p functions for use in the sdk.
These functions could also be copied over to the sdk. I dont have a preference of which is better.
I believe that this, in my testing seems to help the e2e state-sync
tests complete more reliably, by fixing some potential, range-related
slice building, as well as the way the test app hashes snapshots.
Additionally, and I'm not sure if we want to do this, but I added this
hook to the reactor that re-sends the request for snapshots during the
retry. This helps in tests prevent systems from getting stuck, but I
think in reality, it might create more traffic, and operators would
just restart a state-syncing node to get a similar effect.
## Description
- Add `context.Context` to Privval interface
This pr does not introduce context into our custom privval connection protocol because this will be removed in the next release. When this pr is released.
Executed a local network using simapp and looked for logs that seemed superfluous. This isn't by any means an exhaustive grooming, but should drastically help legibility of logs.
ref: #5912
@p4u from vocdoni.io reported that the mempool might behave incorrectly under a
high load. The consequences can range from pauses between blocks to the peers
disconnecting from this node.
My current theory is that the flowrate lib we're using to control flow
(multiplex over a single TCP connection) was not designed w/ large blobs
(1MB batch of txs) in mind.
I've tried decreasing the Mempool reactor priority, but that did not
have any visible effect. What actually worked is adding a time.Sleep
into mempool.Reactor#broadcastTxRoutine after an each successful send ==
manual control flow of sort.
As a temporary remedy (until the mempool package
is refactored), the max-batch-bytes was disabled. Transactions will be sent
one by one without batching
Closes#5796
When set to true, an invalid transaction will be kept in the cache (this may help some applications to protect against spam).
NOTE: this is a temporary config option. The more correct solution would be to add a TTL to each transaction (i.e. CheckTx may return a TTL in ResponseCheckTx).
Closes: #5751
time_iota_ms is intended to ensure that an honest validator always generates timestamps
with time increasing monotonically. For this purpose, it always suffices to have this parameter
set to `1ms`. Allowing users to choose different numbers increases bug surface area.
Thus the code now ignores the user provided time_iota_ms parameter (marking it as unused),
and uses 1ms internally.
The MTU (Maximum Transmission Unit) for Ethernet is 1500 bytes.
The IP header and the TCP header take up 20 bytes each at least (unless
optional header fields are used) and thus the max for (non-Jumbo frame)
Ethernet is 1500 - 20 -20 = 1460

Removes `p2p.FuzzedConnection`, since it does not appear to be in use. While these sorts of test wrappers may be useful, they should be injected directly instead of bleeding through into the main application configuration. We'll implement something similar if and when necessary, for the new P2P abstractions in #2067.
* config: rename prof_laddr to pprof_laddr and move it to rpc
also, remove `/unsafe_start_cpu_profiler`, `/unsafe_stop_cpu_profiler`
and `/unsafe_write_heap_profile` in favor of pprof server functionality.
Closes#5303
* update changelog
* log start
Fixes#828. Adds state sync, as outlined in [ADR-053](https://github.com/tendermint/tendermint/blob/master/docs/architecture/adr-053-state-sync-prototype.md). See related PRs in Cosmos SDK (https://github.com/cosmos/cosmos-sdk/pull/5803) and Gaia (https://github.com/cosmos/gaia/pull/327).
This is split out of the previous PR #4645, and branched off of the ABCI interface in #4704.
* Adds a new P2P reactor which exchanges snapshots with peers, and bootstraps an empty local node from remote snapshots when requested.
* Adds a new configuration section `[statesync]` that enables state sync and configures the light client. Also enables `statesync:info` logging by default.
* Integrates state sync into node startup. Does not support the v2 blockchain reactor, since it needs some reorganization to defer startup.
