Main/Snapshot: only update the machine state on the VM process if there is one, and introduce a new event when a snapshot has been restored instead of abusing t he one for deleting a snapshot.

Main/Machine+Snapshot: fix state checks and introduce standardized state checks for snapshot operations as a safety net

Main/Console+Machine+Session+Snapshot: move the save state and snapshot related methods from IConsole to IMachine, with lots of unavoidable code restructuring and cleanup. Also define two new machine states (so that the "Saving" one is specifically for saving state now) which requires more changes everywhere Frontends: necessary adjustments doc/SDK: document the changes

Main/Medium+Snapshot: make all code recursing over trees (objects containing lists of child objects) use as little stack as possible, and establish safe depth limits to avoid crashes, plus related cleanups in related code areas

Main/VirtualBox: eliminate redundant parameter to i_registerMedium, avoiding bugs with registering e.g. floppy images as hard disks. Main/Medium: switch over to CreateMedium, final API touch-ups, variable name cleanup, typo checking for backend support of fixed image creation, check for backends not supporting a particular device type Frontends/VBoxManage: cleanup, adapt to new API, generalize all operations which worked on hard disks only to all device types Frontends/VirtualBox: adapt to new API

Main/src-server: warnings.

Main/Snapshot: fix broken snapshot deletion, assert became partially bogus, partially redundant

Main: cleanup after r95701

6813 - MachineImpl.cpp - IInternalMachineControl changes.

Main/VirtualBox+Medium+Snapshot: fix lock inconsistency which crept into the previous fixes

Main/Medium+AutoCaller+others: fix medium uninit deadlock caused by lock order violations, sometimes taking the caller before the media tree lock, sometimes after, plus a few other small fixes

Main: AutoCaller/VirtualBoxBase refactoring, cleanly splitting out the object state handling, and moving all caller synchronization to one file. Also eliminated a not so vital template (AutoCallerBase) by much simpler inheritance. Theoretically has no visible effects, the behavior should be identical. Done as a preparation for reimplementing the caller synchronization.

6813 - MachineImpl use of server side wrappers + misc mods on other classes

remove changes that break up log and error strings, introduced in 92972

6813 src-all/ProgressImp.cpp + some formatting/line length sorting

6813 stage 7 VirtualBoxImpl.cpp etc

6813 stage 6 - Make use of server side API wrapper code in all interfaces

6813 - User server side API wrapper code in all interfaces.. stage 4 rev 1

6813 - stage 3 rev 1

Main/Snapshot: block deleting of current snapshot if it has child snapshots, as this would lead to VM config corruption, plus safety belts in the GUI and settings reader

Warnings.

Main/Medium: redesign API level medium locking, needed conversions from MediaList to MediumLockLists in several places, forced cleanups elsewhere, too Main/Token: introduced token objects for controlling the unlocking, will be used as a general concept in the future Main/Snapshot: snapshot deletion needed significant cleanups as it was still using many shortcuts, directly calling the API to lock media instead of using lock lists. Now much better, and the online snapshot deletion is also a lot cleaner as it no longer passes unnecessary parameters around which are already known in the machine/snapshot code Main/MediumLock: small improvements, now has a mode which skips locking already locked media, needed by the Snapshot code where we have overlapping lock lists and have to update the original one instead Main/Console+Session+Machine: follow-up changes for the online snapshot merging parameter passing simplification, plus an unrelated lock order violation fix in Machine which happens only for inaccessible machines Main/testcase: update correspondingly doc: update SDK reference

Main,Frontends: Second step of USB controller rework. There is one controller instance for every USB controller now. Adapt frontends and testsuite to work with the changed API

Main/USB: USB Controller implementation rework. Moved filter handling into a separate interface

Main/xml/Settings.cpp: limit snapshot depth to 250, avoiding crashes Main/Snapshot: limit snapshot depth to 250 Main/Medium: eliminate some spurious error messages when saving a VM config

Main: a couple of whitespace fixes

Main/Snapshot: fragment of code has been replaced by a call isMediumFormatFile()

Main: change API. Interface IMediumFormat was touched. Attribute capabilities got the type MediumFormatCapabilities and option safeArray. PR5434.

Main/Snapshot: fix indentation

Main/SnapshotImpl: Select merge direction based on the image size

Main/Snapshot: the merge procedure became a little bit better. Procedure take into account only those sizes of disks which are essentially needed for carrying out the merge.

Main/Snapshot+Console: Set up logging earlier to capture more error information, and with explicit config allow online snapshots without saving state

Main/Snapshot: re-add a vital fix for taking snapshots which somehow was lost

Main: renavation com::Guid class. PR5744

Main/Machine+Snapshot+Medium: fix cancelling snapshots, used to trigger both backref inconsistency and incorrect lock list/map updates which could cause runtime misbehavior, the config file was already made consistent with the previous changes

Stop cancel operation succeeds ref 5903

Main/Snapshot: issue 4386. Small changes in error messages and log messages.

Main/Snapshot: only check free space on filesystems when the target uses file backing

Main/Snapshot: issue 4386. Check available free space on the storages before merging. Changings for accordance the coding rules

Main/Snapshot: issue 4386. Check available free space on the storages before merging.

Main/Snapshot: stop abusing the mPeer field, because this triggers various settings related problems when loading settings and the like. A SnapshotMachine is not a SessionMachine, and this they shouldn't be treated the same.

Main/Machine+Snapshot: fix crash on snapshot restore due to incorrect saving of settings (#6281)

Main/SnapshotImpl.cpp: eliminate dead code

Main: Implement API to configure autostart/-stop for virtual machines

Main/Snapshot: fix locking problem when taking a snapshot, and when restoring a snapshot.

Main/Machine+Snapshot: add a comment to make it easier to get rid of those time-consuming commits on startup one day

Main/VirtualBox+Machine+Snapshot+Medium: fix lock order issues introduced by new style of medium registry updates

Main/VirtualBox+Machine+Medium: redesign the medium registry save logic, as the local lists in the threads caused inconsistencies with concurrent operations and the return of spurious errors

Main: Extended IMachine and the settings XML with three tracing related properties.

Main/Medium: rework locking scheme to solve lock order violations and long GUI start up time caused by too much locking Main/all: Remove the enter and leave methods from write locks, they cause hard to find locking problems. Better solve them explicitly.

Runtime: new guest OS type for Solaris 11 Frontends/VirtualBox: add new patterns for Solaris 11 guest OS type, reuse the icon Frontends/VBoxManage: more details for "list ostypes" Main/xml: make guest OS type in config file an arbitrary string (still validated/mapped in the old way in the settings code), remove hardcoded limit of 8 network adapters Main/Global: move list of valid guest OS types into a single place, add function to get the network adapter limit for each chipset type Main/Console+Machine+Snapshot+NetworkAdapter+Appliance+VirtualBox+Guest+SystemProperties: consistently use the appropriate network adapter limit so that ICH9 chipset can use 36 network adapters, adapt to cleaned up guest OS type handling, remove leftover rendundant guest OS mapping, whitespace Network/NAT: release log message cosmetics, allow unlimited number of instances, fix maxconn clamping Network/PCNet+VirtioNet+E1000: allow unlimited number of instances

Main: fix setting the current state modification flag in some circumstances

Main/Medium+Snapshot+VirtualBox: extend the API in a compatible way to support skipping the automatic directory creation when creating new images.

Main: Fix wrong medium attachment references after "Restore Snapshot" by making a depth copy of them

Main/Machine: fix the medium registry logic for linked clones. Previously creating a linked clone of a snapshot of a linked clone didn't result in the right medium registry update.

Main/Console+Machine: new method for deleting a range of snapshot, right now not implemented

Main;VBoxManage: more clone vm work

Main/Console+InternalMachineControl: add a (not yet implemented) method which deletes a snapshot including all children. While I was at it I cleaned up the hyperlinks and method/attribute naming, and also marked a few more methods as const.

Main/SnapshotImpl: when restoring a snapshot always save the global registry, see xtracker 5578

Main/SnapshotImpl: progressCallback not used anymore since r70196

Main: implement sharing saved state files between snapshots and machines in 'saved' state; this dramatically speeds up restoring snapshots as well as taking snapshots of 'saved' machines

Main: prohibit setting a UUID as the machine or snapshot name

Main: fix broken snapshots when disk images are shared between several machines

Main: before unregistering a machine, move media shared with another machine to that machine's media registry to prevent that machine from becoming inaccessible

Main. QT/FE: fix long standing COM issue

Main: fix and clarify that ISnapshot::SetName and SetDescription automatically save the machine settings; API docs

Main: source re-org.
