* Fix handling of 5xx responses from OneDrive when performing a session upload
* Switch to same checks when doing non session upload so that OneDrive exceptions are thrown correctly
* Remove a 'throw e' when curl times out
* Remove a needless 'throw e' when a session upload cannot be found
* Set the upload failed flag when OneDrive errors on session uploads
* Add additional JSON object validation for queries made against OneDrive where a JSON response is expected and where that response is to be used and expected to be valid
* Remove 'else throw e' which causes the application to exit / crash and replace with what the actual error message is from OneDrive
* Make logging of unhandled errors consistent
* Add extra error handling when uploading files for errors received from OneDrive or file system errors
* Flag that the upload failed if there is an exception error raised
* Update logging output for when an error occurs to indicate that the file was skipped
* Log the OneDrive response as log.vlog rather than log.error as it is now being handled correctly
* Throw an exception for 50x errors so that it gets caught correctly
* Clean up logging when exception is generated
* Catch a 403 Forbidden exception when attempting to query for an Office 365 Shared Library Name
* Validate that the returned response is a valid JSON object
* Update scopes as per https://github.com/OneDrive/onedrive-api-docs/issues/1119
* Update that if a 403 error is received, what is the right course of action to take
* Without this throw, uploadLastModifiedTime fails to catch that the 412 error was returned, thus, the retry with a null cTag / eTag is not performed which leads to 'OneDrive response missing required 'id' element' being generated.
* Fix 'Unexpected character '<'. (Line 1:1)' when OneDrive has an exception error
* Validate that the response from OneDrive is a valid JSON object
* Update Sharepoint Document Library handling for .txt & .csv files
* Use replace function for modified Sharepoint Document Library files rather than delete and upload as new file, preserving file history
* Add explicit check for hashes to be returned in cases where OneDrive API fails to provide them despite requested to do so
* Add comparison with sha1 if OneDrive provides that rather than quickXor
* Update logging output for better clarity
* Update logging output from vdebug -> error for errors
* Remove restrictive checks on fileDetails - if missing, continue, not return
* Add debug lines for if / when this is missing
* If query for file details or file object generates an error, we return, but we also need to flag that downloadFailed = true so that item is not added to the database which may cause validation issues leading to thinking that the file was downloaded but then deleted
* Update fix for #555 as try | catch block for session creation appears to miss error response codes
* Update how JSONValue object is determined to be valid
* Add error logging when response is not a valid JSON object
* Check if the file that was downloaded to local disk equals the reported size & reported hash of the file on OneDrive. If sizes do not match, report an error and remove the local file as it is most likely corrupt.
* Add a try block when attempting to create the upload session and handle if there is an error response from OneDrive
* Should return a JSONValue regardless of error
The current code requires git even if there is not .git directory.
Switch to piping the output of git directly to the version file,
which makes sure that it is not called during if evaluation.
