A failed read on a UI path (sort change, clear, refresh after a write, opening a
card, the tag picker, the tags tab) used to escape as an unhandled exception.
Reads now run before the view is cleared and report Error_Read_* instead; the
active filter changes only once its query has run. DataWritten and TagsChanged
fire only after a successful refresh, so a broken database shows one dialog.
The compiled SQL chains every atom into one expression, and SQLite rejects
expressions deeper than 1000 levels. A query of about 1000 words parsed but
then failed in SQL, outside the syntax-error handling, and crashed the app.
The parser now rejects more than 256 atoms as a syntax error.
The lexer now keeps token offsets and rejects what the grammar never allowed
but the token rules accepted:
- an empty phrase: "" (matched every card), tag:""
- a phrase touching a word or another phrase: a"b", "a"b, "a""b"
- whitespace between a qualifier and its phrase value: tag: "x"
key:"value" stays the only legal contact; parentheses still delimit phrases.
Listed in PLAN 6.1/6.2 and USAGE.
A backslash right before a pipe, as in the tag name a\|b, turned the escaped
pipe into "\|": the table splitter reads "\\" as an escaped backslash and the
pipe as a column separator, shifting the row. Cells now escape '\' before '|'.
Recorded in PLAN 5.8.
AppendLine wrote CRLF on Windows; the document now uses LF everywhere and
converts CRLF/CR inside card bodies and column descriptions. Column titles and
the workspace name are collapsed to one line like card titles.
With .ykanban present but ykanban.db gone, opening used to create an empty
database and show an empty board without any hint. It now throws
WorkspaceDatabaseMissingException and shows the open-failed page, telling the
user to restore a backup or delete .ykanban and initialize again.
Follows PLAN 4.2: create .ykanban, take the lock, then build the database.
SqliteDatabase.Create writes every migration and the preset columns in a
single transaction and deletes the file again on failure, so no empty
version-0 database is left behind. WorkspaceSession.Initialize keeps the lock
into the session instead of releasing and re-acquiring it.
A lock conflict while initializing shows the lock-conflict page.
Deep nesting overflowed the stack of the recursive Pidgin parser (around
400-700 levels), an uncatchable crash. The depth is now checked on the token
stream before parsing and reported as a syntax error. Listed in PLAN 6.2 and
USAGE.
- board: columns in id order, per-column sort via config, column width presets (240/320/480) and custom 160-720
- column header new-card and edit/delete menu; card menu delete and move-to-column
- card editor as one unit of work with dirty check and discard confirmation; nested tag picker writes new tags immediately
- schema constraint violations mapped to typed exceptions and shown inside the modal
- dialog service with owner stack so nested modals center on their parent and get FlowDirection
- repository: filtered GetCards, CountCards; view-model tests
