0.20.2-beta.0

fix: dfx canister delete fails

dfx canister delete occasionally fails because it attempts to withdraw too many cycles from the canister before it is deleted.
Usually, dfx tries again with a larger margin of cycles, but sometimes this gets stuck.
It is now possible to use --initial-margin to manually supply a margin in case the automatic margin does not work.

perf: improve sync command performance

Improves sync (eg. dfx deploy, icx-asset sync) performance by parallelization:

• Make asset properties query faster by parallelization, significant improvement for canisters that have many assets
• Make chunk creation process faster, by increasing parallelization 4=>25, significant improvement when deploying lots of small assets

icx-asset: add support for log levels, defaulting to info

PocketIC support

Passing --pocketic to dfx start now starts a PocketIC server instead of the replica. PocketIC is lighter-weight than the replica and execution environment internals can be manipulated by REST commands. For more information, see the PocketIC readme.

feat: subaccount can be derived from principal in dfx ledger account-id

feat: dfx info candid-ui-url

dfx info candid-ui-url displays the URL to the Candid UI canister for an explicitly specified --network <network name> (or local by default).

chore: Improve help text of dfx identity new to include which characters are valid in identity names

fix: Capitalization of "Wasm" in docs and messages

The output of dfx canister status has been also changed to use consistent capitalization of words.

fix!(frontend-canister): include .well-known directory by default for asset upload

When uploading assets to an asset canister, dfx by default excludes directories and files with names that start with ..
dfx will start including folders with the name .well-known by default.
It is possible to override this in .ic-assets.json like this:

{
  "match": ".well-known",
  "ignore": true
}

fix: Transferring funds too early in dfx ledger create-canister with --next-to

When creating a canister with dfx ledger create-canister --next-to on a canister that does not exist (e.g., 2vxsx-fae), then the funds are first transferred away from the users account, but the call then fails to create the new canister, and the funds are not returned to the user's account.

feat: reformatted error output

Rather than increasing indentation, dfx now aligns the error causes with a "Caused by: " prefix.

Also changed error types to report error causes as causes, rather than embedding their error cause in the error text.

Before:

Error: Failed while trying to deploy canisters.
Caused by: Failed while trying to deploy canisters.

fix: "Failed to decrypt PEM file" errors messages will now include the cause

feat: Wasm memory soft-limit

Adds support for the wasm_memory_limit canister setting, which limits the canister's heap during most calls but does not affect queries. As with other canister settings, it can be set in dfx canister create or dfx canister update-settings via the --wasm-memory-limit flag, as well as in dfx.json under canisters[].initialization_values.wasm_memory_limit.

feat: extensions can define a canister type

Please see extension-defined-canister-types for details.

feat: init_arg_file in dfx.json

Introduces support for the init_arg_file field in dfx.json, providing an alternative method to specify initialization arguments.

This field accepts a relative path, from the directory containing the dfx.json file.

Note

• Only one of init_arg and init_arg_file can be defined at a time.
• If --argument or --argument-file are set, the argument from the command line takes precedence over the one in dfx.json.

fix: dfx new failure when node is available but npm is not

dfx new could fail with "Failed to scaffold frontend code" if node was installed but npm was not installed.

dfx schema --for dfx-metadata to display JSON schema of the "dfx" metadata.

feat: add tech_stack to the Canister Metadata Standard

The standardized dfx metadata is extended with another object: tech_stack.

chore: updated management canister .did file

feat: added dfx completion command

This command generates shell completion scripts for bash, elvish, fish, zsh, or PowerShell.

Describing how to install shell completion scripts is beyond the scope of this document.
Here are two commands that would enable command completion in the current shell:

In zsh:

In bash:

source <(dfx completion)

fix: dfx no longer always creates .dfx directory if dfx.json is present

Previously, dfx would always create a .dfx directory in the project root if dfx.json was present.
Now, it only does so if the command accesses the .dfx directory in some way.

fix: dfx only loads dfx.json for commands that need it

For example, this will work now:

echo garbage >dfx.json && dfx identity get-principal

0.19.0

fix: call management canister Bitcoin query API without replica-signed query

dfx canister call --query defaults to use "Replica-signed query" feature.

It doesn't work with bitcoin query calls to the management canister because the Boundary Nodes cannot route the read_state call.

Only for these particular queries, dfx will make the query calls without checking the replica signatures.

If the response reliability is a concern, you can make update calls to the secure alternatives.

feat(beta): enable cycles ledger support

If the environment variable DFX_CYCLES_LEDGER_SUPPORT_ENABLE is set and no cycles wallet is configured, then dfx will try to use the cycles ledger to perform any operation that the cycles wallet usually is used for.

The following commands/options have been unhidden:

• dfx cycles
• --from-subaccount for dfx deploy, dfx canister create, dfx canister deposit-cycles to determine which cycles ledger subaccount the used cycles should be used from
• --created-at-time for dfx deploy, dfx create canister, dfx canister deposit-cycles to control transaction deduplication on the cycles ledger
• --to-subaccount for dfx canister delete to control into which subaccount cycles are withdrawn before the canister is deleted

The cycles ledger will not be supported by default until the cycles ledger canister is under NNS control.

feat: dfx canister call ... --output json

This is the same as dfx canister call ... | idl2json, for convenience.

See also: https://github.com/dfinity/idl2json

fix: Output of dfx ping is now valid JSON

Added commas in between fields, and newlines to improve formatting.

fix: canister status output to be grep compatible

dfx canister status now outputs to stdout, rather than stderr, so that its output is grep compatible.

fix: fetching canister logs to be grep & tail compatible

dfx canister logs now outputs to stdout, rather than stderr, so that its output is grep and tail compatible.

fix: fetching canister logs

The management canister method fetch_canister_logs can be called only as a query, not as an update call. Therefore, dfx canister logs <canister_id> now uses a query call for this purpose.

dfx wallet set-name now actually sets the name of the wallet

feat: hyphenated project names

DFX no longer forbids hyphens in project names. Anywhere they appear as the name of a variable, e.g. environment variables or generated JS variables, they will be replaced with underscores.

fix: .ic-assets.json configuration entries no longer overwrite the default for allow_raw_access

Previously, any configuration element in .ic-assets.json functioned as if a setting of
"allow_raw_access": true were present in the json object.

For example, given the following configuration, all files would be configured
with allow_raw_access set to true, as if the second entry specified
"allow_raw_access": true (which is the default), even though it does not.

[
  {
    "match": "**/*",
    "allow_raw_access": false
  },
  {
    "match": "**/*",
    "headers": {
      "X-Anything": "Something"
    }
  }
]

Now, given the same configuration, all files would be configured with allow_raw_access set to false, as expected.

Note that the default value of allow_raw_access is still true.

fix: removed version switching logic

Removed the logic for calling a different version of dfx based on DFX_VERSION or the dfx field in
dfx.json. This is now performed by dfxvm.

feat: --always-assist flag for dfx canister call/install/sign and dfx deploy

When all the arguments are optional, dfx automatically provides a null value when no arguments are provided.
--always-assist flag enables the candid assist feature for optional arguments, instead of providing a default null value.

fix(deps): the second pull forget to set wasm_hash_download in pulled.json

When the dependency has been in the cache, dfx deps pull forgot to set correct wasm_hash_download in pulled.json.

It caused the following init/deploy commands to fail.
