"Professional CMake" book suggest the following:
"Targets should build successfully with or without compiler support for precompiled headers. It
should be considered an optimization, not a requirement. In particular, do not explicitly include a
precompile header (e.g. stdafx.h) in the source code, let CMake force-include an automatically
generated precompile header on the compiler command line instead. This is more portable across
the major compilers and is likely to be easier to maintain. It will also avoid warnings being
generated from certain code checking tools like iwyu (include what you use)."
Therefore, removed the "#include <PreCompiled.h>" from sources, also
there is no need for the "#ifdef _PreComp_" anymore
* distinguish between temp and cache location
* document's transident directory is created in the cache location
* add functions to access temp and cache location via Python
Add new argument to Application::newDocument() to create a temporary
document. Also exposed to Python API App.newDocument() with a named
argument 'temp'.
The temporary document is marked with status bit 'TempDoc'. The user
will not be prompt for saving when closing. The undo/redo is disabled.
The AutoSaver skips it. And the tree view will not show it.
PropertyXLink allows linking to/from object within a temporary document
without saving.
This patch adds support of recomputation with external linked object,
as well as external document auto loading and partial loading.
Application:
* Modified new/openDocument()/signalNewDocument to choose whether to
signal GUI for creating a view for the document. This makes it possible
to suppress view creation when opening external documents.
* New API openDocuments() which does the actual job of loading the
document together with any external dependencies. There are afew
extra arguments to allow setting FileName property differently from
the actual file path, which are required when auto loading
dependencies during document recovery (with future patch to
Gui::DocumentRecovery)
* openDocumentPrivate() is an internal helper for opening individual
document.
* New signalStart/FinishOpenDocument to be signaled before and after
opening a document. There may be multiple depending documents actually
opened in between these two signals.
* New signalBeforeRecomputeDocument signaled before recompute a
document.
* New API addPendingDocument() for use by external capable link
properties' to queue up external documents.
* isRestoring/isClosingAll(), for convenience status reporting.
Document:
* signalFinishImport/RestoreObjects, new signal triggered after imported
or restored all input objects
* signalBeforeRecompute, signaled before start recomputing this document
* Modified signalRecomputed with additional recomputed objects, this is
to make it more efficient for Gui::TreeWidget to check recomputation
result.
* signalSkipRecompute, signal to inform which objects are skipped
during recomputation because of their owner document SkipRecompute
setting.
* restore/save/read/writeObjects() modified to suport partial
loading. See [here](https://git.io/fj6PY) for more information.
* afterRestore(), internal function called to finish restore. The
function is separated from restore() because there is quite a few
critical steps needed to fully restore a document with external
linking. See [here](https://git.io/fj6P4) for more information.
* DocumentP::_RecomputeLog is modified to store more accurate object
recomputation error, including those happened during restore/import.
* isExporting(), new API for checking if an object is exporting.
External linking properties will use this function to decide how to
export.
* copyObject(), modified to support external linking objects, and
accepts multiple input objects.
* moveObject(), modified to support arbitary object moves. The original
implementation may cause crash if undo/redo is enabled. Furthermore,
because the original information fakes the object's deletion to break
its dependency, it does not work for objects that may auto delete their
children when being deleted. The new implementation copy the object,
and than paste it to the other document. It then deletes the input
objects from the original document. In case of recursive move, it only
deletes the depending object if it has an empty in list.
* importLinks(), new API to import any external object linked by the
input objects into this document. It will auto correct all link
references after importing.
* getDependencyList/_rebuildDependencyList(), these two APIs are unified
and implemented by an internal function _buildDependencyList() with a
new algorithm to handle external objects. The returned dependency list
will now include objects from external documents. In case of cyclic
dependencies, getDpendencyList() will report the actual objects
involved in dependency loops.
* mustExecute(), new API to check if there are any object requires
recomputation. This function will call _buildDependencyList() and
check for external objects as well.
* addRecomputeObject(), new API for marking changes during document
restore. It only marks the object but does not actually recompute
them for performance reason. One use case is for geo feature to
request for recomputation to generate geometry topological names.
* recompute(), support partial, external, and inverse dependency
recomputation. Improve error handling during recomputation.
See [here](https://git.io/fj6PO) for more information.
* _recomputeFeature(), suppoert user abort.
* getDependentDocuments/getInList(), new API to obtain an optional
dependency sorted list of depending documents.
DocumentObject:
* Add various ObjectStatus flags
* isExporting/getExportName(), return a safe name for exporting, in the
form of <ObjName>@<DocName>, which is guarrenteed to be unique.
Various link property will save linked object using this name if the
the linked object is exported together with the owner object, see
[PropertyLinkBase::restoreLabelReference()](https://git.io/fj6XO)
for more information.
* recomputeFeature(), add option to recompute this object together with
all its dependent objects.
* canLoadPartial(), new API for [partial document loading](https://git.io/fj6PY).
MergeDocuments:
* Move object name mapping logic to various link properties. See
Base::Sequencer:
* Add new API checkAbort() for checking user abort.
Introduce a new concept of transaction ID. Each transaction must be
unique inside the document. Multiple transactions from different
documents can be grouped together with the same transaction ID.
This makes it possible to undo/redo single operation that contains
changes from multiple documents due to external linking.
Application:
* get/set/closeActiveTransaction() is used to setup potential
transactions with a given name. The transaction is only created when
there is actual changes. If objects from multiple documents are
changed under the same active transaction, they will have the same
trasnaction ID, and can be undo/redo togtether later.
* signalUndo/signalRedo, new signals triggered once after an undo/redo
operation. Unlike signalUndo/RedoDocument, these signals will only be
triggered once even if there may be multiple documents involved during
undo/redo.
* signal(Before)CloseTransaction, new signals triggered before/after an
actual transaction is created or aborted.
AutoTransaction:
* Helper class to enable automatic management of transactions. See class
document for more details. This class will be used by Gui::Command
in later patches to allow better automation of transactions in
command.
Document:
* open/commit/abortTransaction() are now redirected to call
Application::get/set/closeActiveTransaction() instead.
* _openTransaction() is added to do the real creation of transaction.
* _checkTransaction() is modified to create transaction on actual change
of any property.
* getTransactionID() is used to find out the position of a transaction
with a given ID. When triggering undo in external document, it may be
necessary to perform multi-step undo/redo in order to match for the
transaction ID.
Transaction/TransactionObject:
* Various changes for the new transaction ID concept.
* Support undo/redo add/remove dynamic property
