You can trigger it before this fix by running Cvpcb when a .kicad_mod file is
incorrectly set as "Legacy" in your footprint table.
(cherry picked from commit e269b5d1b9)
It's too expensive to fetch the timestamps when the github
server is busy. See Dick Hollenbeck's comments at the top of
github_plugin.cpp for more info.
Also adds some safety to the other caching algorithms after
seeing github_plugin's wild-west usage of the kicad_plugin.
Fixes: lp:1753143
* https://bugs.launchpad.net/kicad/+bug/1753143
Too many external applications fail to touch the parent directory.
Also removes FP_CACHE_ITEM lastMod times and dirty flags as we've
always loaded libraries atomically anyway.
Claws back some of the performance lost by being more efficient
with cache management for sequential calls to Enumerate and then
Load.
Fixes: lp:1750936
* https://bugs.launchpad.net/kicad/+bug/1750936
Smartens the cache freshness checking, and adds checksums of
constituent-directory last-mod-dates to the footprint info
list.
Also inserts the dataPtrs into the list at the same time as
the text to keep wxWidgets from measuring the width of the
text twice (yes, really). And converts the list to default-
column widths in case the wxWidgets patch is present to
greatly speed list creation (by not measuring all that text).
On my machine drops the first-load time from 4s to 2.5s and
the subsequent-load times from 2.5s to < 1s. With the
wxWidgets patch subsequent-loads become near-instantaneous.
- Reverts behaviour of 3e71ed2421
- 3D model offset now explicitly written in mm, using "offset" tag
- Any read "at" tag is converted from inches to mm
- This will not break any 3D model offset when reading files
- It will however render files incompatible with old versions
-Can paste items from board to module-editor (only module parts)
-Can paste entire modules just as copy
-Can copy items inside module-editor
Known limitations:
-Will crash if trying to paste a module containing module_text inside
the module editor ( dont know why, problem existed before )
-If copying things with strange layer names, the layer names will be
changed.
Allow partial library reads in libraries that support footprint per file.
This includes the KiCad and GEDA footprint libraries.
Allow for partially cached libraries rather than ignoring all valid files
when an error occurs.
Currently, kicad_pcb files have a (version ...) tag, but it is ignored. This
commit does the following:
1. Parse the version. If it's later than the last supported version, present an
alternative error message suggesting an upgrade if the file does not load
correctly. The version will be interpreted as an integer YYYYMMDD to suggest
a KiCad release date.
2. Accept a (version ...) tag also in kicad_mod files, but do not write them
yet. If no version tag is present in these files, assume the version to be that
of the current format version at the time of this commit.
This is meant to be merged to the 4.x stable series, and preps for KiCad 5
which will start emitting version tags also in footprints - users with what
will then be 'old stable' will not get a parse error when we introduce this for
footprints, and we can safely increment the format version later.
2) Change from legacy Cu stack to counting down from top=(F_Cu or 0).
The old Cu stack required knowing the count of Cu layers to make
sense of the layer number when converting to many exported file types.
The new Cu stack is more commonly used, although ours still gives
B_Cu a fixed number.
3) Introduce class LSET and enum LAYER_ID.
4) Change *.kicad_pcb file format version to 4 from 3.
5) Change fixed names Inner1_Cu-Inner14_Cu to In1_Cu-In30_Cu and their
meanings are typically flipped.
6) Moved the #define LAYER_N_* stuff into legacy_plugin.cpp where they
can die a quiet death, and switch to enum LAYER_ID symbols throughout.
7) Removed the LEGACY_PLUGIN::Save() and FootprintSave() functions.
You will need to convert to the format immediately, *.kicad_pcb and
*.kicad_mod (=pretty) since legacy format was never going to know
about 32 Cu layers and additional technical layers and the reversed Cu
stack.
Now, nets are saved with consecutive net codes (both modern & legacy plugins).
Zones are saved together with their nets, without depending on the fact if there are any pads with such net. Therefore validation of zone net names was removed (pcbnew/class_board.cpp).
Performed tests:
- Changed a pad's net name from empty to existent - ok, name was changed.
- Changed a pad's net name from empty to nonexistent - ok, error message is displayed, net name stays empty.
- Changed a pad's net name from existent to empty - ok, net name became empty
- Changed a pad's net name from existent to nonexistent - ok, error message is displayed, net name is not changed.
- Drawn a zone that belongs to a net, then modified schematics so the net does not exist anymore. After reloading the net list, all pads/tracks are updated. Zones still belongs to the net that does not exist in the schematic (but still exists in .kicad_pcb file). After running DRC, the zone becomes not filled.
- Undo & redo affects assignment of a polygon to a specific net (you may change net of a polygon, refill it and undo/redo the changes).
- KiCad s-expr & legacy, Eagle, P-CAD boards seem to load without any problem (they also contain correct net names assigned to the appropriate pads). All types of board file formats were loaded, then saved in sexpr format and reopened with a KiCad built from the master branch (without my modifications).
- A few boards were also saved using the legacy format and were opened with the master KiCad without any issues.
- Change a net name for a pad, restore with undo/redo - ok
- Remove everything, restore with undo - ok
- Remove everything, reload netlist - ok
Differences observed between files saved by the master branch KiCad and this one:
- list of nets are not saved in any particular order, so net codes may differ
- the default net class does not contain the unconnected net
comment for GITHUB_PLUGIN which should flow into Doxygen output.
*) Rewrote:
PCB_BASE_FRAME::Save_Module_In_Library(): now uses fp-lib-table and PROPERTIES.
PCB_EDIT_FRAME::ArchiveModulesOnBoard(): now can archive to any writable library type.
PCB_BASE_FRAME::SelectLibrary(): is now generic for selecting a library, not just the active library.
* When loading footprint do not retest every footprint in cache. Only test
the footprint being loaded. Fixes long load times on libraries with a lot
of parts.
* Fix footprint name bug where file extension was added to the end of the
footprint name.
* Fix bug in path equivalence test due to Posix path separators in footprint
library table. Convert paths to native separator before comparison.
* Fix a bug in FOOTPRINT_VIEWER_FRAME::OnActivate() which cause the footprint
list to always get reloaded when using footprint library tables.
* Remove some unnecessary debugging messages.
* Add a few Doxygen comments to FP_CACHE in kicad_plugin.cpp.
standard layer name support from BOARD::GetLayerName(). This function evolved
in a contorted direction over time, and was being asked to return one of 3
different kinds of layer names, even though it only took a boolean to control
that choice.
Users are better served by forcing them to get to know the concise new
English Standard layer names. This is because these concise names show up
in the "pretty" footprint/module files as the standard representation of
both feature and copper layers.
Change the name of BOARD::GetDefaultLayerName() to GetStandardLayerName().
Drop boolean argument to both BOARD::GetStandardLayerName() and
BOARD::GetLayerName().
their type, by using the more abstract PLUGIN::Footprint*() functions.
This is an intermediate phase only, other changes will be necessary as library table support comes in.
Encapsulate usage of library path searching, since that will go away as library table support comes in.
Add FOOTPRINT_EDIT_FRAME::{get,set}LibPath() and FOOTPRINT_EDIT_FRAME::{get,set}LibNickName() functions
to provide this encapsulation.
This required the additional compiler command line option "-std=c++0x".
2) Switch to unique_ptr from auto_ptr which is C++ deprecated.
3) Change to new English layer names per mailing list discussion, see class_board.cpp.
4) When saving to *.kicad_pcb or *.kicad_mod, identify opportunities to use wildcard
layer sets, for pads so far.
5) Switch to two std::string hashtables in pcb_parser.cpp, away from one wxString based one
for layer names and layer sets mapping. One hashtable holds the mask, the other the index.
Layer sets are only in the mask table.
6) Move "LOCALE_IO toggle" into PCB_IO::Format() since it is a public API function and
caller should find it as convenient as possible to use. LOCALE_IO should handle
nesting OK in the case where public Format() is called from one of the Footprint*()
functions.
7) Drop support for "export module to new library". Creating new libraries will have to
be handled in concert with library table entries, and we've talked recently about
creating a better footprint library manager, one that resides in a DLL/DSO. So
this kind of functionality needs to be handled in there in the near future.
8) Change name of exported PCB_IO module/footprint to *.kicad_mod and not *.emp.
* Add footprint methods to PCB_IO.
* Add FP_CACHE and FP_CACHE_ITEM for handling new footprint library design.
* Add code to save legacy libraries in new format.
* Change behavior of BOARD_ITEM::GetLayerName() to return the default layer
name when the item does not have a BOARD as a parent.
* Minor changes to the module output formatter when writing to module library
files (no BOARD as parent).
* Add new (and some that I forgot along the way) CMake flags to
EDA_BASE_FRAME::CopyVersionInfoToClipboard().
* Add -Wno-narrowing to GCC flags to stop GCC 4.7 from complaining about
a conversion from int to unsigned in the Boost polygon library.
* Add INPUT_STREAM_READER to richio.cpp to allow using any object derived
from wxInputStream as a LINE_READER (needs to be validated).
