crash: a panic hook and a locked per-run command journal (adapted from SolidCraft's crash reports). A panic in a command becomes a report with the model from before it and the command; one outside commands, or an unclean exit found at the next start (abort, segfault, a crash in a graphics driver, a kill: what #248 needs), a report with the model the journal starts from (autosave, file or a copy) and the commands since, the last control request and the dead run's log lines. Reports are bounded, deduplicated by signature and replayable (crash::replay, with writes confined to a scratch folder). The crash folder follows the automation temp area in --control and CI runs. logfile: a small size-rotated file logger behind the log facade. bug_report: GitHub bug-form drafts. Version, OS and what happened by default, home folder shown as ~; the command journal only with Share my session, the model only with Include the model as well; a session too long for the link becomes a file to attach and the clipboard text. Commands: diagnostics.crash_reports, diagnostics.crash_report, diagnostics.bug_report (Tools › Help, with its icon) and diagnostics.crash_test (FIELDCRAFT_CRASH_TEST=1 only).

//! Crash reports: enough to reproduce a crash and fix it, without slowing the app down or
|
|
//! filling the disk (docs/crash-reports.md).
|
|
//!
|
|
//! - **Panics** are caught by a hook. One inside a command becomes a report with the model as it
|
|
//! was before the command and the command itself, so `fieldcraft-cli crashes replay <id>`
|
|
//! reproduces it. A panic something inside the command caught and turned into an error is
|
|
//! reported the same way, marked recovered.
|
|
//! - **Crashes no hook sees** (an abort, a stack overflow, a segfault, a crash inside a graphics
|
|
//! driver, the process being killed) are found at the next start: every running app keeps a
|
|
//! small, locked command journal; a journal nobody holds any more belongs to an app that died.
|
|
//! Its report carries the model the journal starts from (the last autosave, the model's file,
|
|
//! or a copy taken when the model was opened) and the commands run since, ending with the one
|
|
//! in flight, plus the app's last control request and the dead run's lines of the log file
|
|
//! ([`crate::logfile`]).
|
|
//! - **Cost**: nothing until [`install`] is called (tests, the CLI and the web build never do);
|
|
//! after that, two small unbuffered appends per top-level command of the app's own model
|
|
//! ([`Session::crash_journal`]), and work only when something panics.
|
|
//! - **Bounded**: the same crash (its signature: place + message, digits ignored) is counted, not
|
|
//! written again; at most [`MAX_NEW_PER_SESSION`] new reports per run, [`MAX_REPORTS`]
|
|
//! reports, [`MAX_TOTAL_BYTES`] on disk, nothing older than [`MAX_AGE_DAYS`] days.
|
|
//!
|
|
//! Reports are folders `crashes/<time>-<signature>/` holding `report.json`, and when known
|
|
//! `model.fieldcraft`, `replay.json` and `log.txt`. Nothing is ever sent anywhere.
|
|
//!
|
|
//! Adapted from SolidCraft's `crates/engine/src/crash.rs` (MIT OR Apache-2.0), see ATTRIBUTION.md.
