Dploy

Changed

- Renamed the CLI --quiet option to --silent because it better reflects the
effect of the option

Fixed

- Fix bug causing unstow to delete dest directory when unfolding.
When unstowing and nearly all actions have been collected additional checking
to find candidates for folding i.e. when a directory contains symlinks to
files that all share the same parent directory. It just so happens that the
dest directory passed into unstow could also meet this same criteria and would
be deleted in error.

- Produce a helpful error when stowing or unstowing with duplicate sources.
Before stow would fail, when conflicts were found, and unstow would succeed in
unstowing a duplicate source the first time, but fail after trying to unstow
nothing. By catching the bug before hand the error message is much clearer.

- Fix bug stowing or linking paths that cannot be relative to each other and
caused a silent failure.
e.g. with windows paths: `dploy stow C:\some\path D:\other\Path`
Since the symbolic links can't use a relative path fallback to the absolute
version of the path passed in.

Removed

Fix

- Added a MANIFEST.in to fix installation via PyPi

Changed

- Added Dates to Change log releases

Fixed

- Fixed change log formatting
- Fix PyPi Package so it can be installed

Added

- Added --ignore argument to stow and unstow commands, to specify patterns file
to ignore.
- Added reading of .dploystowignore files in the directories of sources for
ignore patterns that are additional to those specified via --ignore
- Added optional is_silent & is_dry_run arguments to dploy.stow() dploy.unstow()
and dploy.link(), This is analogous to the --dry-run and --quiet command line
arguments. These function arguments default to is_silent=True and
is_dry_run=False.
- Added redundant check to make sure dploy never deletes anything other than a
symbolic link
- Check for source and dest new consideration was taken for sources
and dests directories that have invalid execute permissions.

Changed

- Check for additional issues with sub commands that are similar to the initial
checks done on the input of stow and unstow
- Prevent redundant errors when the src or dest are not directories
- Clarify some error messages
- Display the user inputted source and dest paths instead of absolute paths in
the output
- Clarify error messages for file and symbolic link conflicts
- Make the output of dploy stow and unstow deterministic across file systems
- Changed the output of failing dploy sub commands so they print as many
detected issues as possible before aborting
- Print all conflicts while stowing instead of just the first conflict, and
print what exactly the conflict is

Fixed

- Fixed issue when unstowing where some stowed packages directories created
during the stowing process via unfolding would not be deleted.
- Fix issue unstowing a folded dir with a stray link
- This fixed the following scenario: Given a dest directory with stowed
packages that share a folded directory, that also contains a stray link
along with the links created by stowing. When the stowed packages are
unstowed Then the folded directory was re-folded using the parent
directory of the single stray link and possibly linking new files that
were never intended to be linked there. When what was desired was the
directory to just remain with the single stray symlink.
- Fix an improperly handled expetion that occurred when unstowing a package that
had it's destination directories execute permission unset.

Added

- Add folding of the remaining links that would be around after calling unstow
- Add Checks for conflicts between multiple sources for stow
- Add checking to see if args are directories for stow and unstow
- Add check the permissions for source and dest before running a command
- Add error handling for source permissions errors for stow and unstow
- CLI: Add a --dry-run flag to show what would be done
- CLI: Add a --quiet option to suppress normal output
- CLI: Add handling for canceling the program with CTRL-C
- CLI: Add a message for case when a source is already unlinked

Changed

- Relicense under MIT
- Make dploy module usage silent
- Clarify message when a source argument is the same the dest argument
- Have the dploy module throw exceptions that the CLI module would handle
instead of just printing to stdout

Fixed

- CLI: Fix link to take only take one source
- Fix link source arg so it takes a string not a list
- Fix console output to print the correct command name e.g. stow, link, and
unstow
- Fix issue where files could be deleted during unstow folding
- Fix bug that would cause an unexpected and unhanded exception when there was
link in the destination directory that pointed to a non existing location in
the source.
- Fix issue in stow and unstow where source and dest could be the same. This
issue made it possible to delete files when unstow had the same
parameters for both source and dest. It also didn't make sense to try to stow
a directory into itself, since there will always be conflicts.

Added

- Adds support for python 3.3
- Add an unstow command to undo stowing

Changed

- Stow command is run in two passes and check for conflicts first before making
any changes

- General bug fixes and improvements.
