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) The function datalad.cmd.get_runner has been removed. (#3104) 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) now understands SSH URLs that have a port in them (i.e. the "ssh://[user@]host.xz[:port]/path/to/repo.git/" syntax mentioned in man git-fetch). (#3146) Interface classes can now override the default renderer for summarizing results. (#3061) run: --input and --output can now be shortened to -i and -o. (#3066) Placeholders such as "{inputs}" are now expanded in the command that is shown in the commit message subject. (#3065) interface.run.run_command 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)
