Previously, we would store the error code in exception data when creating the exception from a libgit2 native error. However, we may also want to _generate_ these exceptions and have them converted to a libgit2 error. (For example, a callback may want to return GIT_EUSER, and so throw a `UserCancelledException`.) Therefore, provide exceptions with knowledge of their corresponding libgit2 error code so that we can round-trip that data. --- .../AmbiguousSpecificationException.cs | 11 ++++- LibGit2Sharp/BareRepositoryException.cs | 14 ++++-- LibGit2Sharp/CheckoutConflictException.cs | 14 ++++-- LibGit2Sharp/Core/Ensure.cs | 30 ++++++------ LibGit2Sharp/InvalidSpecificationException.cs | 14 ++++-- LibGit2Sharp/LibGit2SharpException.cs | 6 --- LibGit2Sharp/LockedFileException.cs | 14 ++++-- LibGit2Sharp/NameConflictException.cs | 14 ++++-- LibGit2Sharp/NativeException.cs | 46 +++++++++++++++++++ LibGit2Sharp/NonFastForwardException.cs | 14 ++++-- LibGit2Sharp/NotFoundException.cs | 14 ++++-- LibGit2Sharp/PeelException.cs | 14 ++++-- LibGit2Sharp/UnmergedIndexEntriesException.cs | 14 ++++-- LibGit2Sharp/UserCanceledException.cs | 14 ++++-- 14 files changed, 181 insertions(+), 52 deletions(-) create mode 100644 LibGit2Sharp/NativeException.cs diff --git a/LibGit2Sharp/AmbiguousSpecificationException.cs b/LibGit2Sharp/AmbiguousSpecificationException.cs index 1d19bbfde..16c77f6df 100644 --- a/LibGit2Sharp/AmbiguousSpecificationException.cs +++ b/LibGit2Sharp/AmbiguousSpecificationException.cs @@ -1,3 +1,4 @@ +using LibGit2Sharp.Core;
