debuginstall: add Python information to debuginstall output (issue4128)
This change adds to the output of "hg debuginstall" information about the
Python being used by Mercurial. It adds both the path to the Python
executable (i.e. the value of sys.executable) and the version of Python
(specifically the major, minor, and micro versions).
Below is an example of what the output looks like after this change.
The marked lines are the new output lines:
$ hg debuginstall
checking encoding (UTF-8)...
-->showing Python executable (/Users/chris/.virtualenvs/default/bin/python)
-->showing Python version (2.7.6)
checking Python lib (/Users/chris/.virtualenvs/default/lib/python2.7)...
checking installed modules (/Users/chris/mercurial)...
checking templates (/Users/chris/mercurial/templates)...
checking commit editor...
checking username...
no problems detected
Note that we use the word "showing" without an ellipsis for the new lines
because, unlike the other lines (except for "Python lib" which will be
adjusted in a subsequent commit), no check follows the display of this
information.
Some commands allow the user to specify a date, e.g.:
- backout, commit, import, tag: Specify the commit date.
- log, revert, update: Select revision(s) by date.
Many date formats are valid. Here are some examples:
- ``Wed Dec 6 13:18:29 2006`` (local timezone assumed)
- ``Dec 6 13:18 -0600`` (year assumed, time offset provided)
- ``Dec 6 13:18 UTC`` (UTC and GMT are aliases for +0000)
- ``Dec 6`` (midnight)
- ``13:18`` (today assumed)
- ``3:39`` (3:39AM assumed)
- ``3:39pm`` (15:39)
- ``2006-12-06 13:18:29`` (ISO 8601 format)
- ``2006-12-6 13:18``
- ``2006-12-6``
- ``12-6``
- ``12/6``
- ``12/6/6`` (Dec 6 2006)
- ``today`` (midnight)
- ``yesterday`` (midnight)
- ``now`` - right now
Lastly, there is Mercurial's internal format:
- ``1165411109 0`` (Wed Dec 6 13:18:29 2006 UTC)
This is the internal representation format for dates. The first number
is the number of seconds since the epoch (1970-01-01 00:00 UTC). The
second is the offset of the local timezone, in seconds west of UTC
(negative if the timezone is east of UTC).
The log command also accepts date ranges:
- ``<DATE`` - at or before a given date/time
- ``>DATE`` - on or after a given date/time
- ``DATE to DATE`` - a date range, inclusive
- ``-DAYS`` - within a given number of days of today
