* exp show: add -n/--num to display the last N commits from HEAD
* exp run: fix empty commit with no changes
* add test for exp show with multiple commits
* allow -n greater than num commits in repo
* review fix
* experiments: move executor into a module
* experiments: separate executor into base/local
* rename LocalExecutor to TempDirExecutor, run in .dvc/tmp by default
* git: restore HEAD using reset not checkout in detached_head()
* experiments: support calling BaseExecutor.reproduce directly for
workspace runs
* experiments: run single experiments in local workspace by default
* update experiments tests for workspace changes
* experiments: update checkpoints for workspace runs
* update checkpoints tests
* update test_show
* add force param for apply
* exp apply: add --force option
* exp run/res: add --temp option to force tempdir execution for single
experiments
* force apply in non-apply specific tests
Currently, we iterate over targets manually in CLI, which results in a
complicated code and a DAG collection/check overhead. With this PR we
collect the DAG once, figure out all the needed targets within it and
just reproduce them in one pass.
* experiments: add utils.exp_commits for iterating over experiment commits
* repo: add support for all_experiments in brancher and used_cache
* git: make all_commits return commits in standard refs instead of --all
* gc: add --all-experiments to preserve cache for experiments
* update gc tests
* repo: support pushing and fetching specific revs internally
* exp push: push cache for experiment by default
* exp pull: pull cache for experiment by default
* fix empty git repo bug
* experiments: commit to refs/exps/... instead of branch heads
* update exp show
* restore checkpoint_resume kwarg
* refactor new() to use experiments stash
* experiments: use refspecs to populate and collect executors
* experiments: use new stash and merge on exp checkout
* experiments: fix executor chdir
* experiments: update run and show
* skip checkout after reproduce
* checkpoints: use experiments refspecs
* check if workspace was stashed before applying
* exp show: unify checkpoint/standalone experiment collection
* git: move iter_refs to backend
* update for scm changes
* experiments: replace exp checkout in favor of exp apply
* git: handle rev_parse errors in resolve_commit
* update refs containing and baseline check
* fix sigint handling for checkpoints
* update checkpoint exists behavior
* fix checkpoint baseline behavior
* update tests
* experiments: update gc
* update show tests
* fix type checking errors
* update diff
* scm: add diff, describe
* experiments: generate human readable names
* exp run/resume: allow user specified exp name with -n/--name
* update tests
* experiments: add `exp branch` for promoting experiment to full branch
* fix test
* fix missing file
* experiments: explicitly close scm instances before cleaning up tmp dir
* experiments: refactor regular/checkpoint experiment separation
* fix scm_checkout pull bug
* experiments: return stages from executor.reproduce
* since executor has to move to threadpool execution anyways, we no
longer have to work around the pickle repro result limitation
* refactor new/resume behavior
* refactor checkpoints tests
* use -f to force checkpoints reset/restart
* checkpoints: use 'exp run' and 'exp res[ume]' commands
* stage: all outs can be missing for checkpoint stages
* regular outputs may not be written at the time a checkpoint is
generated, but subsequent checkouts of that stage should not fail due
to the missing outs
* commit stage on checkpoint generation otherwise non-persist cached outs
are lost
* checkpoints: wait for stage proc to end after killing via terminate()
* stage: fix issues with killing checkpoint stage
* refactor signaling (use threading.Event instead of Condition)
* fix windows bug (kill all child processes via taskkill)
* experiments: refactor executor collection
* tests: move checkpoint tests into separate module
* refactor experiment tests to use stage fixture
* stage: make runs checkpointable
* api: add make_checkpoint API call
* tests: add test for checkpointed stage
* experiments: implement checkpoints callback chain
* initial working state
* use .dvc/tmp for checkpoint signal file location
* force repro for checkpoint experiments
* checkout: add flag to allow missing persistent outputs
(i.e. not yet created)
* use allow_persist_missing on checkpoint experiment repro
* executor: force checkout before checkpoints experiment repro
* move checkpoint commands to `dvc exp run`
* support resuming checkpoint runs with --continue
* fix git bugs
* experiments: include checkpoint commits in `exp show`
* use 1sec sleep timers
* fix apply_workspace test conflict
* tests: add test for `dvc exp run`
* cleanup signal file behavior
* fix bool conversion
* tests: add tests for checkpoint and checkpoint_continue
* fix styling
* fix checkpoint stage test
* fix checkpoint monitor thread condition/notification
* experiments: cleanup show UI
* show git tag/branch names instead of SHAs by default
* make timestamp formatting more like the viewer
* update tests
* place timestamps in their own column
* update command test
* exp: remove unused regex

core.experiments config option is true
