The format is based on Keep a Changelog. This project adheres to Semantic Versioning.
- Added
print-metric-statsandprint-cloudwatch-metricscommands toholochain_metrics#1972.
- Adds support for setting the agent name and id via a parameter with hc run by calling
hc run --agent-name MyAgentName. The%agent_idis generated from the name. This allows multiple hc run conductors to be used on the same machine. It will be overwritten by theHC_AGENTenvironment variable. - Adds support for sim2h with hc run by calling
hc run --networked sim2h --sim2h-server wss://localhost:9000. - Adds support for hApp-bundles to
hc run. This enables complex hApp setups with multiple DNAs and bridges to be easily run during development without having to write/maintain a conductor config file. #1939 - Adds ability to validate entries with full chain validation when author is offline #1932
- Adds a conductor level stats-signal that sends an overview of instance data (number of held entries etc.) over admin interfaces. #1954
- Adds parameters to conductor RPC function
debug/state_dumpto select portions of the state to be send instead of always receiving the full dump (which can get big if the instance holds many entries). #1954 - Added new docker boxes dedicated to faster CI tasks through incremental compilation
- Added
CARGO_CACHE_RUSTC_INFO=1to nix shell
- data sent via jsonrpc to the conductor interface for agent/sign, agent/encrypt and agent/decrypt must now be base64 encoded
- circleci config now uses version 2.1 syntax
- added the
-xflag to several nix-shell commands - using
command -vinstead ofwhichin app specbuild_and_test.sh - standardised all app (proc) spec commands into a single paramaterised command
hc-test-app-spec - updated to holonix
v0.0.54 $CARGO_TARGET_DIRis now set explicitly in the nix shell hook- renamed
hc-conductor-wasm-installtohc-conductor-wasm-bindgen-install - core
shellHookcan now override holonixshellHook - several
--target-dirflags are removed in favour of$CARGO_TARGET_DIR - the passphrase hashing config is now set to faster and less secure parameters to reduce the start-up time of conductors a lot, esp. on slow devices. (will become a setting the user can choose in the future - faster and less secure config is fine for now and throughout alpha and beta) #1986
- paths in cluster test are no longer hardcoded in a way that breaks
$CARGO_TARGET_DIR cliandconductorare now both uninstalled again after running app spec tests- Fixes a panic in the sim2h server that can happen if the last node of a space leaves just as a second node connects. #1977
- Pruning the State of old/stale/history data to prevent it from using up a slowly but infinitely growing amount of memory. #1920
- Exchanged vanilla thread-pool with the futures executor thread-pool from the futures crate. This enables M:N Future:Thread execution which is much less wasteful than having a thread per future. Number of threads in the pool is kept at the default (of that crate) of number of CPUs. #1915
- Replace naive timeout implementation (for network queries / direct messages) that uses a thread per timeout with a scheduled job that polls the State and sends timeout actions when needed (reduces number of used threads and thus memory footprint) #1916.
- Use the im crate for
HashMaps andHashSets used in the redux State. This makes cloning the state much cheaper and improves over-all performance. #1923
- Adds a retry if a net worker cannot be spawned on startup #1870
- Add hdk::version_hash, returning MD5 hash of HDK build environment #1869
- Add --info option to conductor to return info on the version including HDK_VERSION & HASH as well as GIT_HASH & GIT_BRANCH if the binary was compiled from a git repo 1902
- Ability to set storage backend for new instances over RPC #1900
- Tracing of HDK API function calls within a zome function call to be used for debugging and in Holoscape's debug view #1885
- Several improvements to gossip related code, both in sim2h server and core #1884:
- Sim2h server will not just randomly pick a node to fill missing aspects, but it caches the information which aspects are missing for which node and will not ask a node about an aspect it doesn't have (gets rid of the
EntryNotFoundLocallyerror). - In core's list responses: merge authoring list into the gossip list so sim2h has gossip sources that are the authors of entry aspects.
- Clear sim2h server's caches about nodes when they disconnect. Also forget the whole space when the last node disconnectse.
- Sim2h server will not just randomly pick a node to fill missing aspects, but it caches the information which aspects are missing for which node and will not ask a node about an aspect it doesn't have (gets rid of the
DhtStore::holding_listwhich stored only the hashes of entries being held got changed toDhtStore::holding_mapwhich is a map of entry address to set of aspect addresses so we know explicitly which aspects are held for each entry. This helps debugging (and already revealed a bug which is fixed in this version too) and enabled several simplifications in core logic. 1904
- Fix lots of deadlocks by managing threads and encapsulating locks #1852
- Have sim2h let go of nodes if the connection got lost because of an error #1877
- Fixed infinite gossip loop due to non-deterministic creation of virtual chain header headers 1904
- Removes the
__META__fields in a .dna.json that allowed it to be unpacked. Removes thehc unpackageCLI option. #1864
- Adds try-o-rama remote server provisioning via trycp #1780
This also adds nix-shell commands:
hc-trycp-server-installwhich installs the trycp-serverhc-trycp-serverwhich runs the trycp-server
- Adds instrumentation to measure and publish. performance. Introduces
hc-metricscommand to parse logs and generate statistics. #1810
- Adds instrumentation to measure and publish. performance. Introduces
hc-metricscommand to parse logs and generate statistics. #1810
- The sim2h switch-board server is now caching if a node is missing data and periodically checks back in. This makes it more resilient against unforseen problems like connection drops which otherwise could only be recovered through an explicit reconnection of the node. #1834
- DNA is now checked for invalid zome artifacts. Validation callbacks that fail unexpectedly will now panic rather than fail validation.
hc package--strip-metaflag is now--include-meta. #1838
- Loading of instances from storage was broken and ended up in partially loaded states. This got fixed with #1836.
- Allows the HC CLI to generate zomes from template repos. This will by default use the default holochain template repos (holochain/rust-zome-template and holochain/rust-proc-zome-template) but can also point to custom templates in remote repos or locally (e.g.
hc generate zomes/my_zome https://github.com/org/some-custom-zome-template). #1565 - Adds option
--propertytohc hashthat sets DNA properties for hash calculation. #1807 - Adds a prelude module to the HDK. Adding the statement
use hdk::prelude::*should be enough for 90% of zome development #1816 - Adds a special DNA property sim2h_url that, if set, overrides the conductor wide setting for the network configuration variable sim2h_url. PR#1828
- Fixes handling if DNA properties during
hc package. DNA properties mentioned in the DNA's JSON manifest are now included in the package. PR#1828
- Allows the HC CLI to generate zomes from template repos. This will by default use the default holochain template repos (holochain/rust-zome-template and holochain/rust-proc-zome-template) but can also point to custom templates in remote repos or locally (e.g.
hc generate zomes/my_zome https://github.com/org/some-custom-zome-template). #1565 - Adds option
--propertytohc hashthat sets DNA properties for hash calculation. #1807
- Adds the holochain_persistence_lmdb crate and makes this an option for the instance config. This is now the default store implementation. #1758
- Custom signals that are emitted from DNA/zome code ("user" signals) are now send to all admin interfaces to enable UI switching logic in Holoscape #1799
-
Adds a network back-end:
sim2hand all corresponding integration. #1744Sim2h is the next iteration of sim1h. In contrast to sim1h, it does not use a centralized database but a centralized in-memory network that connects Holochain instances like a switch-board.
It is much faster than sim1h and will be able to implement Holochain membranes based on the agent IDs and the
validate_agentcallback.It can be used by configuring conductors like so:
[network] type = "sim2h" sim2h_url = "wss://localhost:9000"
with
sim2h_urlpointing to a runningsim2h_serverinstance.This also adds nix-shell commands:
hc-sim2h-server-installwhich installs the sim2h-serverhc-sim2h-server-uninstallwhich removes the sim2h-serverhc-sim2h-serverwhich starts the server with on port 9000 (can be changed with-p) and with debug logs enabledhc-app-spec-test-sim2hwhich runs the integration tests with networking configured to sim2h (expects to find a running sim2h_server on localhost:9000)
- Fixed the frequent deadlocks that would occur on conductor shutdown #1752
- Adds the
--properties/-pflag tohc packagewhich takes a stringifed JSON object to be inserted in the .dna.json under the properties field. This will alter the DNA hash and can therefore be used for fork DNAs from their source code. #1720 - Adds publishing of headers again after rollback. Header publishing is now its own action rather than part of the
Publishaction that plays nicely with the testing framework. It also adds header entries to the author list so they are gossiped properly. #1640. - Adds some deadlock diagnostic tools to detect when any mutex has been locked for a long time, and prints the backtrace of the moment it was locked #1743
- Updates to work with version 0.0.13 of lib3h #1737
-
Adds publishing of headers again after rollback. Header publishing is now its own action rather than part of the
Publishaction that plays nicely with the testing framework. It also adds header entries to the author list so they are gossiped properly. #1640. -
Adds new networking back-end
sim1hwhich can be configured in conductor config with:[network] type = "sim1h" dynamo_url = "http://localhost:8000"
-

dynamodbanddynamodb-memory
-
Adds zome+function name to ConsistencyEvent::Hold representation for pending zome function call returns for better hachiko timeouts. #1725
-
Adds
UUIDto DNA configs which will change the DNA when initializing an instance with it and sets the given UUID. This disables the hash check of the DNA if set. #1724 #1725
- Converts app-spec tests to the new multi-conductor try-o-rama #1725
- Fixes several conditions that lead to occasional deadlocks #1725
- Adds EncryptedSeed and seed.encrypt() allow for easy passphrase encrypting/decrypting of any of the existing seed types. Adds the MnemonicableSeed trait allows seeds to be converted to/from BIP39 mnemonics. #1687
- added nix for
hc-conductor-installandhc-conductor-uninstallbased oncargo#1689 - When loading a hand-written or generated conductor config containing a TestAgent (
test_agent = true), rewrite the config file so that the test agent'spublic_addressis correct, rather than the arbitrary value that was specified before thepublic_addresswas actually known. #1692
- ConsistencySignal "events" are now serialized to strings before being emitted. #1691
-
If there is an HDK mismatch in the zome, a warning is thrown.Also gives ability to get current HDK version in zomes#1658
-
Conductor API debug functions added:
debug/running_instances: returns array of running instance IDsdebug/state_dump: returns a state dump for a given instancedebug/fetch_cas: returns the content for a given entry address and instance ID
Also added the source to the state dump. #1661
-

- Bump dependent crate versions (holochain_persistence 0.0.7, holochain_serialization 0.0.7, lib3h 0.0.10) in preparation futures 0.3.0-alpha17 which will allow us to shift to the upcoming Rust 1.38.0 beta #1632
-
State dump debugging: A new config flag got added that activates dumping of core's redux state every ten seconds in a human readable form: #1601
-
The static file server has been replaced and now uses the Nickel crate intead of Hyper. It now correctly sets content type headers and can be configured to bind to a different address in the conductor config toml #1595
-
Optimized get_links so that fewer network calls are made overrall #1607
-
DEPRECATION WARNING, conductor static UI server is to be removed in an upcoming release. Devs will receive a warning when starting a conductor with a UI server configured PR#1602
- When using agent config with
test_agent = true, the conductor was checking thepublic_addressfield against the generated keystore. No longer so. PR#1629
- Breaking Change genesis function now renamed to init #1508
- BREAKING: Zomes must now include a
validate_agentcallback. If this rejects in any zome the DNA will not start. This can be used to enforce membrane requirements. #1497 - Added a
get_links_countmethod which allows the user to get number of links by base and tag #1568### Changed - The Conductor will shut down gracefully when receiving SIGINT (i.e. Ctrl+C) or SIGKILL, also causing a graceful shutdown of an attached n3h instance, if running #1599
- Fixed problem with
hc runthat was introduced by Conductor config sanitizing a week ago: The conductor config now needs to include the correct hash of each configured DNA file. #1603 adds the proper hash to the internally created conductor config thathc runruns.
- Discrepancy between DNA hashes are now checked and reported to the user through logs #1335.
- Breaking Change Validation callback now shows consistent behavior when called on the authoring node during entry commit time, and when called by validating nodes being requested to hold the entry. In both cases the a FullChain validation package now does NOT include the about-to-be-added entry. Some validation functions were relying on the behavior of having the entry be at the top of the chain in the Hold case, and using the EntryLifecycle flag value to distinguish the two cases. Please note that in the future this flag may be going away! #1563
- Breaking Change Format of
.hcbuildfiles that are run byhcchanged:stepsis now an array so we have deterministic ordering of build steps. - In order to apply WASM size optimizations to our app-spec test suite, we had to make more sophisticated use of the.hcbuildfiles with a sequence of consecutive steps. The former implementation with a map had to changed to an array. #1577
- The EntryLifecycle flags in validation may be going away. If you have a use-case that requires this, please tell us.
- Added
propertiesto entry definitions (not to the entries themselved). These can be retrieved using theentry_type_propertiesHDK function #1337 - Breaking Change Added type field to conductor network configuration. You must add
type="n3h"for current config files to work. #1540 - Added
EncryptionandDecryptionmethods in the HDK #1534 - Adds
hc hashCLI subcommand. Can be used to compute the hash of the DNA in the current dist directory or passed a path to a DNA with the --path flag #1562 - Adds a --dna flag to the CLI so
hc runcan run DNAs outside the standard ./dist/ directory 1561
- Added
Crud Statusinformation to link data in get_links as well as query throughLinkStatusRequest#1337 - The
hctool can now generate template zomes that use the new proc macro HDK #1511 - Added a MVP implementation of Signals that introduces
hdk::emit_signal(name, payload)#1516
-
The barebones tests produced by
hc initnow use the Diorama testing framework rather than holochain-nodejs #1532 -
Breaking change -
holochain_core_types_deriveandholochain_core_typesare split intoholochain_json_derive,holochain_json_api,holochain_persistence_api#1505 -
Fix dangling references of
core_types_deriveand related imports #1551
- Breaking change - renames
emit_trace_signalstosignals.tracein conductor config #1431 - "Consistency" signals added, which aid determinism in end-to-end tests, configurable through
signals.consistencyconductor config #1431 - Uses regex matching for
get_linkstags and type. Probably not a breaking change but be careful of subset matching (e.g.somewill match againstsome-tagbut^some$will not.) #1453 Tombstonefunctionality added on eaviquery, this makes sure that the delete links is not determined by order but determined by atombstone setwhich takes precedence over everything. #1363
- Breaking change - migrates nodejs_conductor and nodejs_waiter to holochain-nodejs repo #1510
- Error log output added for errors occurring during
hdk::call, including bridge call errors #1448. - New
uuidparameter foradmin/dna/install_from_file, to set the UUID of the installed DNA, changing its hash #1425 - BREAKING: Conductor configuration checks for bridges added #1461. Conductor will bail with an error message if the configuration of bridges between instances does not match the bridge requirements defined in the caller instance's DNA (required bridge missing, DNA hash mismatch, trait mismatch) or if a bridge with the handle specified in the config can not be found in the caller's DNA.
- Added a Vagrant file to support nix-shell compatible VMs on windows etc. #1433
- Adds TryInto implementation from JsonString to generic result types. This makes bridge calls much easier to implement safely #1464
- Changes the responses when using
hdk::callto call across a bridge to make it consistent with calling between zomes #1487
- Adding bridges dynamically via an admin interface works now without rebooting the conductor. #1476
hdk::queryresults are filtered now to not contain DNA entries since they can easily be several MBs of size which breaks our current limitation of 640k of WASM memory. #1490

NETWORKING_CONFIG_FILEfor specifing the location of the json file containing the network settings used by n3h. #976 - Adds an environment variable
HC_SIMPLE_LOGGER_MUTEfor use in testing which silences logging output so CI logs won't be too big. #960 - Adds Zome API function
hdk::sleep(std::time::Duration)which works the same asstd::thread::sleep.#935 - All structs/values to all HDK functions must implement
Into<JsonString>andTryFrom<JsonString>(deriveDefaultJsonto do this automatically) #854 - HDK globals
AGENT_ADDRESS,AGENT_ID_STR,DNA_NAMEandDNA_ADDRESSare now set to real, correct values. #796 hc runnow looks for the --interface flag orHC_INTERFACEenv var if you want to specify thehttpinterface [#846]((holochain#846)- NodeJS Conductor added to allow running conductors for testing purposes in JavaScript. #1007
- Scenario API added to enable deterministic scenario tests for zome functions. See the NodeJS Conductor README for details. #942
hdk::holochain_core_types::time::Iso8601now supports validation and conversion to DateTime, and is sortable. #917hdk::query_resultAPI supports return of ChainHeader and/or Entry data for the matched EntryType(s) #868- Admin RPC functions added to container interface. Any (websocket) container interface that is configured with
admin = truenow can call a number of functions to remotely change any aspect of the container config. #840 - Adds a set of functions to the container RPC for managing static UI bundles and HTTP interfaces to these. See rustdoc of
conductor_api::interface::ConductorApiBuilderfor a full description of these functions. #919 - Conductor can now serve static directories called ui_bundles over HTTP that can be configured in the container config toml file. This HTTP server also implements a virtual json file at "/_dna_connections.json" that returns the DNA interface (if any) the UI is configured to connect to. Hc-web-client will use this to automatically connect to the correct DNA interface on page load. #885
- Adds Zome API function
hdk::remove_link(base,target,tag)for removing links. #780
- build problems because of changes to upstream futures-preview crate #864
- Networking: beyond mock, using n3h #831
- Bridging now works and is configurable in the container (no capabilities yet) #779 & #776
- Validation across network #727
- API/HDK: #831
- Conductor: #942
- configuration builder and config files
- http interface #823
