As described in Issue 16849, the existing Tools::getUniqueName method
requires calling code to form a vector of existing names to be avoided.
This leads to poor performance both in the O(n) cost of building such a
vector and also getUniqueName's O(n) algorithm for actually generating
the unique name (where 'n' is the number of pre-existing names).
This has particularly noticeable cost in documents with large numbers
of DocumentObjects because generating both Names and Labels for each new
object incurs this cost. During an operation such as importing this
results in an O(n^2) time spent generating names.
The other major cost is in the saving of the temporary backup file,
which uses name generation for the "files" embedded in the Zip file.
Documents can easily need several such "files" for each object in the
document.
This update includes the following changes to use the newly-added
UniqueNameManager as a replacement for the old Tools::getUniqueName
method and deletes the latter to remove any temptation to use it as
its usage model breeds inefficiency:
Eliminate Tools::getUniqueName, its local functions, and its unit tests.
Make DocumentObject naming use the new UniqueNameManager class.
Make DocumentObject Label naming use the new UniqueNameManager class.
This needs to monitor DocumentObject Labels for changes since this
property is not read-only. The special handling for the Label
property, which includes optionally forcing uniqueness and updating
links in referencing objects, has been mostly moved from
PropertyString to DocumentObject.
Add Document::containsObject(DocumentObject*) for a definitive
test of an object being in a Document. This is needed because
DocumentObjects can be in a sort of limbo (e.g. when they are in the
Undo/Redo lists) where they have a parent linkage to the Document but
should not participate in Label collision checks.
Rename Document.getStandardObjectName to getStandardObjectLabel
to better represent what it does.
Use new UniqueNameManager for Writer internal filenames within the zip
file.
Eliminate unneeded Reader::FileNames collection. The file names
already exist in the FileList collection elements. The only existing
use for the FileNames collection was to determine if there were any
files at all, and with FileList and FileNames being parallel
vectors, they both had the same length so FileList could be used
for this test..
Use UniqueNameManager for document names and labels. This uses ad hoc
UniqueNameManager objects created on the spot on the assumption that
document creation is relatively rare and there are few documents, so
although the cost is O(n), n itself is small.
Use an ad hoc UniqueNameManager to name new DymanicProperty entries.
This is only done if a property of the proposed name already exists,
since such a check is more-or-less O(log(n)), almost never finds a
collision, and avoids the O(n) building of the UniqueNameManager.
If there is a collision an ad-hoc UniqueNameManager is built
and discarded after use.
The property management classes have a bit of a mess of methods
including several to populate various collection types with all
existing properties. Rather than introducing yet another such
collection-specific method to fill a UniqueNameManager, a
visitProperties method was added which calls a passed function for
each property. The existing code (e.g. getPropertyMap) would be
simpler if they all used this but the cost of calling a lambda
for each property must be considered. It would clarify the semantics
of these methods, which have a bit of variance in which properties
populate the passed collection, e.g. when there are duplicate names..
Ideally the PropertyContainer class would keep a central directory of
all properties ("static", Dynamic, and exposed by ExtensionContainer and
other derivations) and a permanent UniqueNameManager. However the
Property management is a bit of a mess making such a change a project
unto itself.
This adds isNullOrEmpty string helper that cheks if string is... well
null or empty. It is done to improve readability of the code and better
express intent.
Every basic data type is stored in Base module, color is standing out as
one that does not. Moving it to Base opens possibilities to integrate it
better with the rest of FreeCAD.
Ensures:
* _class_ is based on BaseClass
* _class_ parameter includes a namespace
And when _class_ is a document object
* namespace is not global namespace
* namespace name is in path after /src/ or /src/Mod/
The document object requirements are needed to auto import modules when using addObject
This updates the `Document.copyObject` Python API by allowing for
keyword arguments and aligning the documentation with the C++ API.
This can make the Python code more readable, by using the keywords form:
```python
document.copyObject(obj, recursive=True, return_all=False)
```
Previous keyword-less version tested and still working for backwards
compatibility.
When in console mode, some messages from CLI interaction still resulted
in popup dialogs, e.g. the response from `--help` or `--version`. This
is becasue those information are communicated via exceptions and those
exceptions prevented the console mode from being properly set.
By using a scope guard the console mode flag is now evaluated in all
cases. The code to display those messages got refactored into dedicated
methods which now also take care of console mode.
