When BookInfo is opened for a book with no existing cache, epub.load(true, true) triggers a 1-2s full parse. Show a "Loading..." popup with progress bar so the device doesn't appear frozen. Popup only appears on the fallback path — cached books load silently. Same pattern for XTC books. Made-with: Cursor

# BookInfo Loading Popup for Unopened Books
|
|
|
|
**Date**: 2026-03-09
|
|
**Task**: Show a progress popup when BookInfo needs to parse an unopened book
|
|
|
|
## Changes Made
|
|
|
|
### BookInfoActivity.cpp
|
|
|
|
Added a "Loading..." progress popup with progress bar to `onEnter()` when the book cache doesn't exist and a full parse is required:
|
|
|
|
- **EPUB branch**: `epub.load(false, true)` is tried first (fast, cache-only). If it fails, `GUI.drawPopup(tr(STR_LOADING))` is shown at 10%, `epub.load(true, true)` runs (slow full parse), progress updates to 50%, thumbnail generation runs, then progress hits 100%.
|
|
- **XTC branch**: Checks `Storage.exists(xtc.getCachePath())` before `xtc.load()`. If cache directory is missing, shows the same popup pattern around load + thumbnail generation.
|
|
- For books with existing cache, no popup is shown — the fast path completes silently.
|
|
|
|
## Build Result
|
|
|
|
Build succeeded — 0 errors, 0 linter warnings. RAM: 30.3%, Flash: 95.7%.
|
|
|
|
## Follow-up
|
|
|
|
- Test on device: open BookInfo for a book that has never been opened, verify popup appears
|
|
- Verify no popup appears for books that have been previously opened/cached
