Matthias Koefferlein 4be134e293 LEF/DEF reader recognizes existing layers by name now 
This is helpful as it assigns layer/datatype numbers
automatically. If only a name is given for a layer
(i.e. "OUTLINE"), it will not match any previously
loaded layer and layer matching goes by layer/datatype
first.

This way, every "reload" added a new "OUTLINE" layer.

Matthias Koefferlein d6ee473d72 Fixed issue #1799 (Can't set cell properties by script) 2024-07-25 22:36:46 +02:00
Matthias Koefferlein 0dd6fca51e Implemented a fix for #1794 (giant meta info produces invalid GDS) 
This fix solves two problems:
* Too large meta info data
* Too many meta info entries

The first problem is fixed by splitting the strings that serialize
the meta info.

The second problem is fixed by introducing prefixed strings that
indicate the attribute index within the string, not inside
the PROPATTR record.

The solution is backward compatible, although old versions will
not read all meta info and skip entries that exceed the GDS
capacity.

Caveat: the produced GDS files may contain duplicate PROPATTR
keys. This is not strictly illegal, but some third-party processors
may drop such entries.

Matthias Koefferlein c70e622590 Fixing issue #1724 (avoid duplicate LEF files) 2024-05-30 16:21:52 +02:00
Matthias Koefferlein 81872d41f0 Fixed a problem triggered by the new foreign layout handling 
Problem was that with forward-referenced text strings
in OASIS, StringRef objects were created (string placeholders).
Those where not properly migrated when transferring the foreign
layouts into DEF space, causing a memory corruption issue.

This solution is to provide a central, singleton string
repository. This needs to be MT safe (reference counting)
which should also fix potential problems when accessing
StringRef-based Text objects from multiple threads.

Fixed issue #1592 (DXF reader issue) (#1595)

Issue 1609 (#1613) 
* Fixed issue #1609 (Cell.read doesn't read LayoutMetaInfo)

This also includes some more functions:
- Layout#merge_meta_info, Layout#copy_meta_info
- Layout#clear_all_meta_info
- Cell#merge_meta_info, Cell#copy_meta_info

In addition, meta info is merged when importing a layout from
another file (Layout/Import -> Other Layouts into current).

* Meta info support in layout diff (for testing), implemented meta info merge for GDS and OASIS readers with special conflict resolution modes

* Undo support for meta info - this way we do not loose meta info when we delete a cell and undo
