ENH: run: Use expanded command for commit summary #3065

merged 2 commits into from Dec 5, 2018

The unexpanded form can be pretty uninformative (e.g., "python {input}").

The next commit will need cmd_expanded to be defined, even in the
inject=True case.

didn't spot any test "visualizing" the effect, but if I got it right -- couldn't expanded form for {inputs} become prohibitively long for becoming a commit summary?

No, it's abbreviated by _format_cmd_shorty if needed.

No, it's abbreviated by _format_cmd_shorty if needed.

Or, if that means "doesn't this increase the odds the command exceeds _format_cmd_shorty's length and is truncated?", then yes. I think that tradeoff is worth it, and that either way there will be scenarios where the default message is worthless. (Overall though I don't particularly care one way or the other and think we should encourage users to give custom messages.)

so instead of something like

[DATALAD RUNCMD] nicecommand -i {inputs} --analysis useful_info --another-useful option -o {outputs}

we will see smth like

[DATALAD RUNCMD] nicecommand -i sub-01/ses-some/anat/sub-01_ses-some_T1w.nii.gz sub-02/...

Sure thing there is still the original cmd in the run record so it could be looked at, and otherwise commit summary seems to just provide redundant with it information. I guess because of such present redundancy I have no strong opinion.

I also have no strong opinion. We should not forget that there is --message, which beats all flavors of automatic.

OK, that gives three explicit "no strong opinions", and, aside from what I've already said, I have nothing to add in support of my weak preference for expanding the command. Whoever feels like being decisive: merge it if you want it, close it if you don't.

We should not forget that there is --message, which beats all flavors of automatic.

I unsurprisingly agree given the "we should encourage users to give custom messages" in my post above :]

 A variety of bugfixes and enhancements

 ### Major refactoring and deprecations

 - All extracted metadata is now placed under git-annex by default.
   Previously files smaller than 20 kb were stored in git. ([#3109])
 - TODO: get_runner #3104 and pending #3131

 ### Fixes

 - Improved handling of long commands:
   - The code that inspected `SC_ARG_MAX` didn't check that the
     reported value was a sensible, positive number. ([#3025])
   - More commands that invoke `git` and `git-annex` with file
     arguments learned to split up the command calls when it is likely
     that the command would fail due to exceeding the maximum supported
     length. ([#3138])
 - The `setup_yoda_dataset` procedure created a malformed
   .gitattributes line. ([#3057])
 - [download-url] unnecessarily tried to infer the dataset when
   `--no-save` was given. ([#3029])
 - [rerun] aborted too late and with a confusing message when a ref
   specified via `--onto` didn't exist. ([#3019])
 - [run]:
   - `run` didn't preserve the current directory prefix ("./") on
      inputs and outputs, which is problematic if the caller relies on
      this representation when formatting the command. ([#3037])
   - Fixed a number of unicode py2-compatibility issues. ([#3035]) ([#3046])
   - To proceed with a failed command, the user was confusingly
     instructed to use `save` instead of `add` even though `run` uses
     `add` underneath. ([#3080])
 - Fixed a case where the helper class for checking external modules
   incorrectly reported a module as unknown. ([#3051])
 - [add-archive-content] mishandled the archive path when the leading
   path contained a symlink. ([#3058])
 - Following denied access, the credential code failed to consider a
   scenario, leading to a type error rather than an appropriate error
   message. ([#3091])
 - Some tests failed when executed from a `git worktree` checkout of the
   source repository. ([#3129])
 - During metadata extraction, batched annex processes weren't properly
   terminated, leading to issues on Windows. ([#3137])
 - [add] incorrectly handled an "invalid repository" exception when
   trying to add a submodule. ([#3141])
 - Pass `GIT_SSH_VARIANT=ssh` to git processes to be able to specify
   alternative ports in SSH urls

 ### Enhancements and new features

 - [search] learned to suggest closely matching keys if there are no
   hits. ([#3089])
 - [create-sibling] gained a `--group` option so that the caller can
   specify the file system group for the repository. ([#3098])
 - Interface classes can now override the default renderer for
   summarizing results. ([#3061])
 - [run]:
   - `--input` and `--output` can now be shortened to `-i` and `-o`.
   - Placeholders such as "{inputs}" are now expanded in the command
     that is shown in the commit message subject. ([#3065])
   - `` gained an `extra_inputs` argument so
     that wrappers like [datalad-container] can specify additional inputs
     that aren't considered when formatting the command string. ([#3038])
   - "--" can now be used to separate options for `run` and those for
     the command in ambiguous cases. ([#3119])
 - The utilities `create_tree` and `ok_file_has_content` now support
   ".gz" files. ([#3049])
 - The Singularity container for 0.11.1 now uses [nd_freeze] to make
   its builds reproducible.
 - A [publications] page has been added to the documentation. ([#3099])
 - `GitRepo.set_gitattributes` now accepts a `mode` argument that
   controls whether the .gitattributes file is appended to (default) or
   overwritten. ([#3115])
 - `datalad --help` now avoids using `man` so that the list of
   subcommands is shown.  ([#3124])
