previous behavior that had inadvertently been changed. In recent
versions, "load <absolute_path> -dereference" would incorrectly
apply the dereferencing to <absolute_path> rather than just its
subcells. Cleaned up the code around DBCellRead() in the process,
so everything is more straightforward (although probably more
could be done in that regard).
dereferencing, and making the behavior of "load" on the command
line (i.e., loading a cell from a file) the same as the
behavior of loading a cell as a result of expanding an unloaded
instance. In both cases, if "load -dereference" is used, and
a cell does not exist in any search path but does exist in the
original location, without dereferencing, then the cell will be
loaded from the original location. Also: Corrected an error
that has existed since adding the capability to read compressed
files, which causes magic to crash when attempting to run the
"crash recover" command (because that routine was mixing
compressed and regular file stream calls).
of a label from the command line. Also fixed a long-standing
irritation that "setlabel" would change the properties of a label
in the edit cell but not in the selection itself, which would
cause the label to be drawn both with the original properties
in the selection and the new properties in the edit cell. Now
both views will track the same changes.
the timestamp is updated after reading in CIF or GDS, and managed to
get the timestamp dirty flag to remain clear after reading when
"gds datestamp" is used. This includes a modification of the timestamp
update routine that only updates timestamps on a single file if only a
single file is being written.
to allow a cell to be flushed with dereferencing (i.e., discard any file
path attached to the cell, and use the search paths to find the cell when
it is reloaded).
unique" code. It was using DBEraseLabelsByContent() which would
erase all matching labels, and could potentially erase labels that
were still remaining on the list being processed, causing a segfault.
Also corrected minor errors identified by valgrind during debugging
the above-referenced problem.
caption line in the GUI window, which was causing problems with
long filenames overrunning the string array dedicated to the caption
line. Thanks to Sylvain Munaut for the patch.
only at the time of running the command "load". But cells are generally
loaded only on an as-needed basis, so the dereferencing option must be
saved as a flag in the cell and honored whenever its subcells are expanded
or otherwise read at a later time.
rid of redundant port entries in subcircuits. There is still an outstanding
issue as to whether nodes and connections need to be recursively iterated
to the hierarchy bottom. The current fix corrected the test case. Also,
added a "-dereference" option to the "load" command to revert to the
original behavior of using only search paths from "addpath" when searching
for files to load.
