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'
```
closes#2498
solves part of #3365
Note: difficult to test the event emit in SwitchToFastSync part, might need to change `stateSyncReactor` to an interface in the `nodeImpl` struct
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.
## Description
- separate docs related to running nodes into the nodes dir.
- keep old files but dont display them
- bring over debugging like a pro blog
Closes: #XXX
## Description
Add a sentence on `initial_height`.
There will be a section in the spec repo explaining the genesis more in depth as this is something that will affect both clients
Closes: #XXX
* docs: goleveldb is much more stable now
Refs https://github.com/syndtr/goleveldb/issues/226#issuecomment-682495490
* rpc/core/events: make sure WS client receives every event
previously, if the write buffer was full, the response would've been
lost without any trace (log msg, etc.)
* rpc/jsonrpc/server: set defaultWSWriteChanCapacity to 1
Refs #3905Closes#3829
setting write buffer capacity to 1 makes transactions count per block
more stable and also reduces the pauses length by 20s.
before: https://github.com/tendermint/tendermint/issues/3905#issuecomment-681854328 net.Read - 20s
after: net.Read - 0.66s
* rpc/jsonrpc/server: buffer writes and avoid io.ReadAll during read
## Description
Add missing metrics.
`Blockchain/v2` exposes metrics for events. I don't find these as something a node operator should utilize as it does not bring insight.
Closes: #XXX
* 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
Reduce the number of targets and make the buildsystem more
flexible by parsing the TENDERMINT_BUILD_OPTIONS command
line variable (a-la Debian, inspired by dpkg-buildpackage's
DEB_BUILD_OPTIONS), e.g:
$ make install TENDERMINT_BUILD_OPTIONS='cleveldb'
replaces the old:
$ make install_c
Options can be mix&match'd, e.g.:
$ make install TENDERMINT_BUILD_OPTIONS='cleveldb race nostrip'
Three options are available:
- nostrip: don't strip debugging symbols nor DWARF tables.
- cleveldb: use cleveldb as db backend instead of goleveldb;
it switches on the CGO_ENABLED Go environment variale.
- race: pass -race to go build and enable data race detection.
This changeset is a port of gaia pull request: cosmos/gaia#363.
