datalad.api.check_dates(paths, reference_date='@1514764800', revs=None, annex='all', no_tags=False, older=False)

Find repository dates that are more recent than a reference date.

The main purpose of this tool is to find “leaked” real dates in repositories that are configured to use fake dates. It checks dates from three sources: (1) commit timestamps (author and committer dates), (2) timestamps within files of the “git-annex” branch, and (3) the timestamps of annotated tags.

Parameters:
  • paths (sequence of str or None) – Root directory in which to search for Git repositories. The current working directory will be used by default.
  • reference_date (str, optional) – Compare dates to this date. If dateutil is installed, this value can be any format that its parser recognizes. Otherwise, it should be a unix timestamp that starts with a “@”. The default value corresponds to 01 Jan, 2018 00:00:00 -0000. [Default: @1514764800’]
  • revs – Search timestamps from commits that are reachable from these revisions. Any revision specification supported by git log, including flags like –all and –tags, can be used. [Default: None]
  • annex ({'all', 'tree', 'none'}, optional) – Mode for “git-annex” branch search. If ‘all’, all blobs within the branch are searched. ‘tree’ limits the search to blobs that are referenced by the tree at the tip of the branch. ‘none’ disables search of “git-annex” blobs. [Default: ‘all’]
  • no_tags (bool, optional) – Don’t check the dates of annotated tags. [Default: False]
  • older (bool, optional) – Find dates which are older than the reference date rather than newer. [Default: False]
  • on_failure ({'ignore', 'continue', 'stop'}, optional) – behavior to perform on failure: ‘ignore’ any failure is reported, but does not cause an exception; ‘continue’ if any failure occurs an exception will be raised at the end, but processing other actions will continue for as long as possible; ‘stop’: processing will stop on first failure and an exception is raised. A failure is any result with status ‘impossible’ or ‘error’. Raised exception is an IncompleteResultsError that carries the result dictionaries of the failures in its failed attribute. [Default: ‘continue’]
  • result_filter (callable or None, optional) – if given, each to-be-returned status dictionary is passed to this callable, and is only returned if the callable’s return value does not evaluate to False or a ValueError exception is raised. If the given callable supports **kwargs it will additionally be passed the keyword arguments of the original API call. [Default: None]
  • result_renderer ({'default', 'json', 'json_pp', 'tailored'} or None, optional) – format of return value rendering on stdout. [Default: ‘tailored’]
  • result_xfm ({'datasets', 'successdatasets-or-none', 'paths', 'relpaths', 'metadata'} or callable or None, optional) – if given, each to-be-returned result status dictionary is passed to this callable, and its return value becomes the result instead. This is different from result_filter, as it can perform arbitrary transformation of the result value. This is mostly useful for top- level command invocations that need to provide the results in a particular format. Instead of a callable, a label for a pre-crafted result transformation can be given. [Default: None]
  • return_type ({'generator', 'list', 'item-or-list'}, optional) – return value behavior switch. If ‘item-or-list’ a single value is returned instead of a one-item return value list, or a list in case of multiple return values. None is return in case of an empty list. [Default: ‘list’]
