Copy Handler Files

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
This is the ALPHA version of Copy Handler. Should only be used for testing purposes - DO NOT USE ON YOUR IMPORTANT FILES!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

This revision (1.40alpha-svn465) includes many bugfixes incorporated throughout the last 2 years,
but at the same also some major changes in the core engine which is unstable and buggy at the moment.

There are still some changes I'd like to include in version 1.40 before releasing it:
- rewrite the copy/move sub-operation for improved performance and reliability,
- switch task info storage from normal files to the sqlite database for improved reliability.

Because those changes are quite significant (especially the first one), there is no point in reporting bugs for this alpha release.
The real testing&fixing phase will come afterwards.

Below you can find the list of changes made between version 1.32 Final and 1.40alpha-svn465:

Bugfixes:
---------

Bugfix: incorrect shutdown of application.
Bugfix: Fixed serialization problem (data streams were opened in text mode instead of binary).
Bugfix: Fixed potential problems with file handle leaks in certain situations when copying files.
Bugfix: got rid of some deadlocks when handling progress info.
Bugfix: dereferencing NULL pointers caused crashes and deadlocks in some cases.
Bugfix: wrong handling of multiple input paths (task copied the first file over and over).
Bugfix: Crash when double-clicking on 'All' task in mini view.
Bugfix: wrong calculations of the processed/total size.
Bugfix: unhandled exception when loading task data from file.
Bugfix: 100% of a processor used by the clipboard monitoring thread.
Bugfix: Fixed potential problem with constant re-reading drive id.
Bugfix: restored resume functionality.
Bugfix: importing paths from file didn't work properly.
Bugfix: task stopping (pause/cancel/kill) did not work properly when in copy files phase.
Bugfix: potential problem with auto-continuation of operation when enough space on disk appears (when showing 'not enough space on disk' dialog).
Bugfix: filtering incorrectly shown in status dialog.
Bugfix: Fixed incorrect memory management in drive detection mechanism (closes [#3169973]).
Bugfix: Fixed problem with language not being read at startup when no configuration file was present.
Bugfix: shell extension controller returned pointer to unallocated memory.
Bugfix: fixed an infinite loop when iterating over files in a directory in some cases.
Bugfix: exiting CH while copying data caused status to be changed to finished; this prevented auto-resuming at the next launch.
Bugfix: Tasks loaded at startup did not start automatically when the status was right.
Bugfix: invalid priority was set for the thread in custom copy dialog.
Bugfix: deleting files while moving was not working.
Bugfix: corrected fast-move operation to skip fast-moving when path already exists or access denied (i.e. different volumes).
Possible fix for problem with activation context when launching CH (exception thrown from CMainWnd::OnCreate() caused Create() to fail).

Translations:
-------------

Added Dutch translation made by Jurgen@CH-CF.
Updated German translation by White-Tiger.

Under the hood:
---------------
Rewritten major parts of the copy engine for improved performance and reliability(!)
Improved storing/loading operation progress mechanism.
Improved support for x64 architecture.
Removed unused option "Copying/Use auto-complete files".
Improved responsiveness for operations on tasks.
Various code cleanups.
Reduced amount of information stored in the task description files.
Changed task identification from time(NULL) to an uuid string.
Rewritten internal configuration system to use boost::property_tree.
Changed the way temporary files are handled - now there are 4 files per task -> .cht with strict task definition, .cht.rstate with rarely changing contents, .cht.ostate with often changing contents and .cht.log with log file.

Features/options removed:
-------------------------
Removed functionality creating n copies of the original file - it made code more complicated, preventing core code from rewriting (hopefully nobody uses it).
Removed option 'auto-resume on error' - wasn't really used, did not work properly.
Removed configuration option "Create log file" - most of the logging was done without taking this option into consideration.
Removed 3 not implemented (anymore) configurations settings:
	- "Show visual confirmation dialogs"
	- "Use timed confirmation dialogs"
	- "Time of showing confirmation dialogs"
Removed 'advanced' button from status dialog (along with rename input paths functionality which was rather useless).
Improved shell extension support:
	- renamed 'shell extension' to 'integration with system'
	- enabling integration will automatically check for compatibility (previously only after ch's restart)
	- on startup, when integration is disabled, notification dialog box will allow to enable it again.
Changed the way shell extension communicates with CH from binary protocol to XML.
Rewritten most of the shell extension code to allow more fine-grained control of the items that appear in menu (also to possibly add new options in the shell menus).
Replaced buffer type detection algorithm with the one that should work reliably on any system.
Disabled enforcing drive detection mechanism - some fixed drives (i.e. TrueCrypt volumes) does not report physical drive location.
Improvements in scanning directory subtask.
Added new subtask class handling fast move operation before scanning directories for files.
Updated installer script to the newest version of InnoSetup (unicode).
Lots of refactoring.

New features:
-------------
Feature: Added two new task options to allow changing the generated name for the file in case copy is done inside single directory.
Feature: Added support for very long paths.
Feature: Added portable mode in case configuration file is found in the executable directory.
Added command-line option '--ImportTaskDefinition' allowing launching operations copy/move operations.
