The implementations of ISystemIO.FileOpenWrite call File.OpenWrite,
which does not truncate the existing file. As such, if we overwrite a
larger file with a smaller one, tail remnants of the existing file will
remain.
Since most of the put operations involve unique filenames, this is only
a problem when overwriting existing files (e.g.,
duplicati-verification.json).
This fixes a regression introduced in revision 71c6aca8a7 ("Fixed IO
calls in Filebackend") from pull request #3456. The previous
implementation called File.Open with FileMode.Create, which truncates
existing files.
This fixes#4486.
This updates all projects to target .NET Framework 4.7.1. The
TencentCOS and Tardigrade backends depend on .NET Standard 2.0. When a
.NET Framework prior to 4.7.1 is targeted, the system cannot be sure
that all the dependencies exist, so it copies all dependent assemblies
to the output directory. This causes many assemblies from the System
namespace to become bundled in the release.

We had previously attempted to make individual projects target 4.7.1
(see pull request #4242), but this can cause compatibility issues when
4.6.2 projects depend on 4.7.1. projects.
This will require Mono 5.10.0 or greater (previously, we required 5.0.0
or greater).

This fixes issue #4234.
- no code changes except those noted below
- projects upgrade to 4.6.2
- wixinstaller project upgraded automatically by VisualStudio
- wixinstaller updated to require 4.6.2
- Library.Encryption changed to Standard2.0 so accommodate update to SharpAesCrypt
Using strong-named assemblies can cause difficulties with the GNU LGPL
license, which allows for one to recombine or relink their application
with modified versions of the code. While one solution is to share the
private key so that people can sign the assemblies themselves, this
would break the trust that is expected from signed assemblies. For now,
the easiest fix is to simply not sign the assemblies. Note that by
doing so, we prevent the code from being referenced from other signed
assemblies.
This also fixes an issue introduced in revision ba94d36a80 ("Added
auto-update for WindowsService and Service."), where the WindowsService
project (signed) referenced the AutoUpdater project (not signed).
We also removed instances of <SignAssembly>false</SignAssembly> to be
consistent with newly created .csproj files that do not contain the
SignAssembly element.
This was motivated by the discussion in issue #2814.
By changing to IEnumerable, it is possible to iterate only a portion of the list, which is useful when not all entries are needed (e.g., when testing a connection).
All existing backends have been updated, and any which were able to be changed to yield return results in a straightforward way now do.
Many backends had a try/catch in the List() method. Due to the fact that yield returns can't be placed within a try/catch block, these have been refactored to either scope the try/catch to the parts that (should) be the only places throwing exceptions, so that exceptions are still caught and handled.
Note that lazy evaluation may cause some changes in behavior - exceptions that were previously thrown at the point of invokation of List() may now be thrown while it is being enumerated.
I believe this will not be problematic though, as the only well-known exception seems to be FolderMissingException, which should be thrown by Test(), but TestList() attempts to enumerate the list to force this exception.
Any places that require the legacy behavior can get it by simply converting the lazy enumerable to a List()
It also makes quota enabled backends return an instance of this interface instead of the quota components separately.
This way, getting quota stats requires only a single remote request on backends like Google Drive and OneDrive.
