Installer: fix 'clean install' over existing installation.

Whenever the target of an installation is a partition that is not empty, the
Installer prompts the user whether they would like to continue with a 'clean
installation', i.e. an installation that clears out the system folder,
excluding the settings, and cleanly installs the assets in the source's
system folder. At all other locations the source data is merged, meaning that
the source version is copied in place.

The logic that clears out the existing /system/ directory stopped working. This
change moves that logic from the copying process, to where it is run before any
file is copied. The added advantage is that the system folder is now properly
cleaned up, also stray files under the system folder will be removed.

This change does not change the logic of what constitutes a 'clean install'.
There are arguments to be made that it should potentially also drop the
settings files, as well as clean out the user's home folder for stray
add-ons, but that really is different functionality, and at this points I
think the requirements for that are not yet fleshed out.

The change was manually tested.

Installer: Remove `level` parameter from CopyEngine

The level parameter in the CopyEngine::CollectCopyInfo() and
CopyEngine::Copy() methods was introduced in hrev30395 to allow the CopyEngine
to decide which directories should be copied. Since then, this
class has been rewritten and it is no longer necessary for that purpose.

This change refactors the CopyEngine and removes the
level parameter from the class interface. Furthermore, it was broken to begin
with; it was passed as reference to the internal recursive _Copy() and
_CollectCopyInfo() methods, meaning they acted like a global counter. The
global counter was increased at the beginning and decreased at the end of those
methods. Execution could terminate early though, leaving the level counter out
of sync with the recursion level.

There is one use of the level parameter, namely in the
WorkerThread::EntryFilter::ShouldClobberFolder() method, but the use of the
parameter was wrong (it would have been at level 3 at the point of the check,
not level 2) and the logic is functional without the level check.

Installer: fix an issue where file attributes were not copied

The issue was introduced when the original CopyFile() and CopyFolder() methods
were integrated into a single recursive Copy() method in
bf551d3889bfdce1e2250df307d505d88fe6c4e1

The installer originally followed the principle that attributes are not copied
for target directories that already exist. Unfortunately the new logic to
filter out that case disables attribute copying in recursive calls of this
method, thus breaking things like bookmarks and tracker templates.

installer/CopyEngine: don't return values via class states

_CollectCopyInfo uses fBytesToCopy and fItemsToCopy for the sole purpose
of returning the scan results. This variable in turn was used to add to
the amount of files to copy in the progress bar, causing it to grow
exponentially with every CollectTargets calls.

With the current use case, the variable would have to be reset to 0
everytime CollectTargets is invoked, making it rather useless as a class
state.

This commit turns those variables into _CollectCopyInfo return values,
and also fix the exponential growth of the progress bar target.

installer/CopyEngine: now only exposes a Copy() method

Previously this class exposes two methods:
- CopyFile(): only copy the file data, nothing else.
- CopyFolder(): copy files & directories between two folders, while
preserving the attributes as well as symlinks.

With this commit, everything is unified into one method: Copy(). This
method can handle files, directories, symlinks and optionally also copy
attributes. Since most of the logic was just moved around, we can be
rather certain that this won't disrupt CopyEngine behaviors by much.

In the future we should look into using BCopyEngine to replace the
copying part of CopyEngine, as they seems to be compatible.

This change allows the Installer to make use of CopyEngine as a
general-purpose copier, in preparation for optional .hpkg installation
support.

Installer: Fix use-after-free of target directory name.

When CopyEngine::_CopyFolder() would recursively call itself, the
fCurrentTargetFolder would be set to the entry name of that directory.

for the next entry.

* Renamed CopyEngine to WorkerThread, since it's used for other things than
just copying.
* Removed the code borrowed from Tracker.
* Removed the InstallerCopyLoopControl, since the CopyEngine handles
notifications and cancelling by itself now.
* Renamed a few message constants.
* Since we only support BFS partitions as install targets, I removed the
FS type from the target menu item label. However, I am going to solve this
differently. I guess all partitions should be seen in the target list, just
disabled if they are not a valid target, and with a reason given too.

root folder as before switching the CopyEngine.
* Add a button "Write Boot Sector" that makes the selected target volume

* Small improvements in the CopyEngine, collecting the source size should be
even a bit faster now since we can use the file size from the already
performed stat().

Sorry, this is a bit of a mess yet and needs more refactoring...
* I've implemented my own copy engine which runs a separate writer thread.
Especially when installing from one hard drive to another, it should speed
things up. When installing from CD, the entire harddisk write time should
at least disappear in the CD read time. When installing from/to the same
drive, the new routine is as fast as the Tracker code that was used before.
* When stopping/canceling the copy process, the copy engine will now actually
block, instead of happily going on while the alert is showing. I've
still implemented that to not leave incomplete files around, like before.
* There is now a progress bar, based on data bytes in files to copy. Reason
being that it's quite fast to collect this info versus also scanning all
attributes.
* The copy engine itself was used in another project before and was tested
with SHA256 hashes of the original files and the copied files, so I think
it can be trusted.
* There is now a lot of code that can be removed or should be cleaned up.
What was the "CopyEngine" should become the "WorkerThread" or something.
* I still had a mental TODO about skipping the swap file (there is none on
CDs, but when copying a harddisk installation there may be one), I just
remembered this when typing this commit message... will fix that next.

* Only except BFS partitions as target volumes. Installer does not initialize
partitions by itself. When it does, this check can be removed again... for
now DriveSetup is to be used and so there is no code duplication.
* Check if the target volume is non-empty and present an appropriate warning.

* Do not try to prevent read-only partitions, we will/should initialize it
with BFS anyways.
* Use the partition path, not the parent path. This also makes displaying IDs

it isn't BFS... (like perhaps ISO9660 with write-overlay ;-)
* Reject a lot more situations as valid targets. (No more devices when they
already have child partitions, no more extended partitions themselves, also
use a minimum size.)

would be interested in this.

Make the Installer ignore /var at it's new location. The old location is also
still checked, in case one uses the Installer to copy an old installation.

* Finished ProgressReporter
* Integrated ProgressReporter into CopyEngine and UnzipEngine.
* Integrated unzipping to main installer engine. Since there are currently no
.zip files in the _packages_ folder (and not even a _packages_ folder
itself), this is completely invisible, but it works.

TODO: Adjust the build system to optionally copy packages into _packages_
instead of extracting them. Like for the CD build profile mode.

Ignore some more entries from the bootable CD. Should fix ticket #4403, test
pending.

Extracted SemaphoreLocker into it's own file.

Update the progress bar more often during file copies (every 2 MB instead of
every 10, which was not smooth enough).

Changed the somewhat bold BLocker usage to a more straight forward semaphore
based mechanism to pause and eventually cancel the WorkerThread. This also works
now when the CopyEngine is still collecting file informartion (ticket #4153).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31912 a95241bf-73f2-0310-859d-f6bbb57e9c96

Increase the file handle limit.

* Fixed problems when installing onto non-empty target volumes. The
'system' folder will be a clean copy of the source volume. Other
folders will be merged (as before), but in case a folder is in the
way of a link or file from the source volume, it will now be purged.
* Clarified the alert for non-empty target volumes, so it is very clear
what happens. (Maybe there ought to the be option to only copy the system
folder, though.)
* Fixed a problem with copying attributes in certain cases.
* Fixed the main GUI not resetting state properly after encountering an
error during the copy process.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31042 a95241bf-73f2-0310-859d-f6bbb57e9c96

Build fix.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30604 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Refactored the way targets are collected before copy process begins, this
way, the optional packages (if there would be any) can be collected as well
before the actual process starts and the progress bar will reflect them
correctly. Before this change, the progress bar would have reset itself for
every optional package.
* In one of my previous commits, I added the error, if there was any, to the
reset message. Now the Installer window looks for the error and tells the
user about it.

Cleanup round 2:
Renamed CopyEngine2 back to CopyEngine.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30601 a95241bf-73f2-0310-859d-f6bbb57e9c96

First round of cleanup:
* Renamed CopyEngine to WorkerThread, since it's used for other things than
just copying.
* Removed the code borrowed from Tracker.
* Removed the InstallerCopyLoopControl, since the CopyEngine handles
notifications and cancelling by itself now.
* Renamed a few message constants.
* Since we only support BFS partitions as install targets, I removed the
FS type from the target menu item label. However, I am going to solve this
differently. I guess all partitions should be seen in the target list, just
disabled if they are not a valid target, and with a reason given too.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30600 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Fixed GCC 4 build and warnings.
* Used std::vector in BlockingQueue instead of Ingo's Vector until I can figure out the GCC4 problems.
This is untested, but I will test this on another machine in a minute.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30423 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Prevent to copy the "var" and "_packages_" folders from the source volume
root folder as before switching the CopyEngine.
* Add a button "Write Boot Sector" that makes the selected target volume
bootable without performing an installation. Adjusted the status message
after installation to be more descriptive.
* Small improvements in the CopyEngine, collecting the source size should be
even a bit faster now since we can use the file size from the already
performed stat().


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30395 a95241bf-73f2-0310-859d-f6bbb57e9c96

Sorry, this is a bit of a mess yet and needs more refactoring...
* I've implemented my own copy engine which runs a separate writer thread.
Especially when installing from one hard drive to another, it should speed
things up. When installing from CD, the entire harddisk write time should
at least disappear in the CD read time. When installing from/to the same
drive, the new routine is as fast as the Tracker code that was used before.
* When stopping/canceling the copy process, the copy engine will now actually
block, instead of happily going on while the alert is showing. I've
still implemented that to not leave incomplete files around, like before.
* There is now a progress bar, based on data bytes in files to copy. Reason
being that it's quite fast to collect this info versus also scanning all
attributes.
* The copy engine itself was used in another project before and was tested
with SHA256 hashes of the original files and the copied files, so I think
it can be trusted.
* There is now a lot of code that can be removed or should be cleaned up.
What was the "CopyEngine" should become the "WorkerThread" or something.
* I still had a mental TODO about skipping the swap file (there is none on
CDs, but when copying a harddisk installation there may be one), I just
remembered this when typing this commit message... will fix that next.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30394 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Only except BFS partitions as target volumes. Installer does not initialize
partitions by itself. When it does, this check can be removed again... for
now DriveSetup is to be used and so there is no code duplication.
* Check if the target volume is non-empty and present an appropriate warning.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30382 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Do not try to prevent read-only partitions, we will/should initialize it
with BFS anyways.
* Use the partition path, not the parent path. This also makes displaying IDs
really superfluous.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30375 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Make the source selection not accidentally reject the boot partition because
it isn't BFS... (like perhaps ISO9660 with write-overlay ;-)
* Reject a lot more situations as valid targets. (No more devices when they
already have child partitions, no more extended partitions themselves, also
use a minimum size.)
* Remove the partition ID from the menu item name. I don't know why the user
would be interested in this.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30335 a95241bf-73f2-0310-859d-f6bbb57e9c96

* CopyEngine::CopyFolder() forgot to GetName(name) before using "name" in
strcmp()

* added checks for installing on source volume, or boot volume
* added alert for file error: lots of errors happening when updating a volume:
* it seems BEntry::IsDirectory() returns false whereas it should return true for some directories
this is to be checked with a test app
* boot volume is now marked automatically as the source volume (a rule is yet to be found for the target volume)
