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.
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.
- DIALOG_CHOOSE_COMPONENT has footprint select widget
- FOOTPRINT_SELECT_WIDGET
- FOOTPRINT_CHOICE widget (customized wxComboCtrl)
- FOOTPRINT_FILTER class
- FOOTPRINT_INFO rework:
- FOOTPRINT_ASYNC_LOADER to load without freezing UI
- Rewrite loader threads as queue-driven thread pool
- Make FOOTPRINT_INFO available via kiway
- FP_LIB_TABLE::PrefetchLib
- Access to global fp-lib-table via kiway
- SYNC_QUEUE threadsafe queue template
- Remove KICAD_FOOTPRINT_SELECTOR build option
