* Rather than force exit if unable to lock the database, add a function and boolean to control if the database access has been init was successful. If not, use the exit scopes to exit the application
* Fix that the --resync option is wrongly enforced when the OneDrive client is started with --list-shared-folders option or other non-sync options. This only happens when configuration changes are detected.
* When enabling system logging to a log file, the actual ERROR line is forced to a new line in the application log. The reason for this is the \n prefix in the error message, which was in place so that when performing CLI logging or systemd logging, the error message would be displayed clearly. This change removes the \n from the actual error message, but inserts a newline before the error message is displayed (and also in some cases post error message) - thus keeping the application runtime look and feel, but improving the application log output.
* Change the exit code of the application when a --resync is required from a generic exit code of 1 to exit code 126, as 126 is supposed to be used when a command invoked cannot be executed - which, in this case, when a --resync is needed - the original command cannot be executed.
* This allows|enables watching for a 126 error code in automated environments, so that when 126 as the exit code is seen, the command can be re-tried potentially automatically with the appropriate resync arguments added.
* Implement --display-running-config to display the running configuration as used at application startup
* Add ONEDRIVE_DISPLAY_CONFIG variable to control --display-running-config in Docker environments
* Only safe remove the files from the local file system if these are exclusively available for this running instance to perform a delete - otherwise this allows multiple clients to perform a --resync on the same data, which, could lead to a data loss scenario
* When the client needs to exit due to an issue, ensure that the curl http instance is shutdown before the exit is performed. This also potentially solves some segmentation faults seen on Ubuntu|Debian platforms due to issues in the shared library libphobos2-ldc-shared.so.X
* Update OneDrive API response handling for National Cloud Deployments
* Add developer option to allow easy switch between /children and /delta to query OneDrive for changes
* Only update the database if the item modified time is different, otherwise we are needlessly updating the database with data that is the same
* Generating a file hash, during the file integrity check is computationally expensive. Only generate a file hash if the modified time of the file is different, otherwise it is pointless to generate the file hash during each integrity check
* Only flush SHM and WAL post integrity check
* Implement a check to validate local filesystem available space before attempting file download
* Implement 'space_reservation' config option with a default value of 50 MB
* Prevent the original run-away logging error message 'Failed initialization on handle XXXX' from occurring if the system is out of space
* Update documentation and man page
* Fix where if the --confdir as specified has incorrect parent permissions, the client is unable to read the required hash files, thus cause an application crash
* When opening files, we should only be opening them as read-only
* When we write out any hash files. they should only be readable|writeable by the userid that is running the application
* Force a synchronization of a specific folder, only when using --synchronize --single-directory and ignoring all non-default skip_dir and skip_file rules
* When using the application with 'defaults' with logging enabled and no verbose mode, the application output that a sync process has started & finished is only written to the logfile every 5 sync times (25 mins). This change updates this so that, if defaults are being used with logging enabled and no verbose mode, the application will always, at a minimum, write out to the application log file when a sync was started and when it was completed. This provides important reference in the log as to when an activity began and was completed.
* In some scenarios users may have a running background service syncing data (systemd or otherwise). In these events, running the application in standalone mode can create a conflict when attempting to perform database queries when there are significant changes to data structures occurring. This PR specifically checks if the database operation files are present, and, if these are present (meaning the application is most likely currently operational) fail fast and not execute the application as a second instance against the same active configuration.
Potentially also resolves RBZ2061430 and RBZ2075468
* Update logging output when running in --monitor --verbose mode in regards to the inotify events
* Add additional logging specifically for delete event to denote in log output the source of a deletion event when running in --monitor mode
* Extend GitHub version check to be done once per day when running in --monitor
* Change notification to also notify GUI if notifications are being utilized
* Add application version check, to check GitHub latest release tag and compare to the application version being run. If the application version is older, display a warning message that the client is obsolete and unsupported and that the user needs to upgrade their client version.
* Add --disable-download-validation to allow downloading files from OneDrive where SharePoint and the OneDrive API mis-represents the values in the API as compared to the actual HTTP server response sent to the client. In the API JSON response we get a "size" value of X, but the HTTP Server Content Length reports a size of Y. When this occurs, the download will report as failed. This was seen as part understanding the cause of https://github.com/abraunegg/onedrive/discussions/1667
* When in --monitor mode, and there are multiple driveId being used (shared folders), when a deletion event occurs, search the DB using all the known driveids rather than just the default one. When using just the default driveid, if the file to be deleted resides on another drive, the following error message is printed: 'Item cannot be deleted from OneDrive because it was not found in the local database' - which is not entirely accurate as the item is in the database, it is just not being searched for correctly.
* Revert the config & logpath change introduced via #1267 as the logging path should not be the value checked, the input path is what should be checked
* Fix logging output when processing downloaded files to remove potential ambiguity as to what events are actually occurring with individual file events post download
* Improve application startup when using --monitor when there is no network connection to the OneDrive API
* Retry network connection test when using --monitor
* Only initialise application if OneDrive API is reachable
