Revert "Switch to Bazel 5 (#12935)" (#12974) 
This reverts commit 4c0118df4d.

This breaks passing -p to bazel test for Haskell tests, e.g.,

bazel test //compiler/damlc/tests:integration-v1dev --test_arg -p
--test_arg InterfaceEq

which breaks with something horrifying like

moritz@adjunction ~/daml (main)> bazel test //compiler/damlc/tests:integration-v1dev --test_arg -p --test_arg InterfaceEq

Dev-env

This folder contains the development dependencies of this project.

Development

Structure

  • dev-env/lib/dade-common is the script meant to be included into all wrappers for dev-env provided tools and other dev-env specific tools (e.g. dade-info)
  • dev-env/lib/dade-dump-profile is a script which outputs - in porcelain mode - all environmental variables necessary for dev-env to function in a given shell.

Debugging

Run your comment with DADE_DEBUG=1 as prefix, e.g.:

DADE_DEBUG=1 jq

Environmental variables

Dev-env uses a common set of variables across it, here are they listed to be documented in future.

Public interface:

These variables are either used for dev-env initialization or are exported by dev-env for external tools to consume.

  • DADE_REPO_ROOT - root of a working directory where dev-env currently is executing; mutable content; input and output.
  • DADE_VAR_DIR - points to a directory which is meant for storing persistent and mutable data; mutable content; if not set, can be derived from DADE_DEVENV_DIR; input and output.
  • DADE_DEVENV_DIR - directory named dev-env under $DADE_BASE_ROOT, assume to be immutable (not yet the case); has to be set before dade-dump-profile is executed; input and output.
  • DADE_DESIRED_NIX_VERSION - user can provide this variable in their profile to silence the warning (in future, disable automatic installation of) the supported Nix version.

Private:

These variables are set in some of the dev-env tools and scripts and are not guaranteed to be always present in the dev-env environment (e.g. not guaranteed to be set by dade-common).

  • DADE_BASE_ROOT - root of the dev-env package; the directory which contains dev-env and nix directories, assume its immutable.
  • DADE_BUILD_RESULT - after a dev-env provided tool is built this variable is exported to point to a nix store where the tool was built.
  • DADE_DEBUG - sets -x in shell environemnt where dev-env scripts are executed.
  • DADE_CURRENT_SCRIPT_DIR - current directory of the currently running/sourced script, corresponds to $BASH_SOURCE[0], assume its immutable.
  • DADE_CURRENT_COMMAND - the name of the current command executed by dade
  • DADE_GC_ROOTS - points to a directory named gc-roots under DADE_VAR_DIR which contains Nix garbage collection roots and hashes for each dev-env provided tool individually; always mutable.
  • DADE_LIB_DIR - points to a directory lib under DADE_DEVENV_DIR which contains libraries for dev-env usage, assume its immutable.
  • DADE_NIXPKGS - points to a GC root which is a symlink to a Nixpkgs snapshot used by dev-env, used only in dade-dump-profile.
