yetone d5619d5a92 windows: an account list read while another magpie writes it is waited for, not taken for no accounts (Packing1 on Discord, Windows 11: 早上更新重启后之前登录的Antigravity订阅供应商和账号都没了 … 整行都没了，供应商里面antigravity直接消失了) — on Windows a file being renamed over (every write magpie makes: a temp file renamed onto it) is, for a moment of up to ~2ms, "The system cannot find the file specified" to anyone else looking at it, with MoveFileEx and with POSIX-semantics renames alike. filememo.Read gave that back as an error, readLogins as no accounts, and whatever change came next (any account's read-modify-write) wrote the empty list back: every built-in account gone, its subscription with it. Measured on Windows 11 (10.0.0.132): one process replacing a 200 KB file, another stat-ing and reading it, saw the file "not there" in a few windows each 20 s. Now steady.Stat and steady.ReadThere wait out a moment of a file not there (15 tries a millisecond apart, Windows only), and filememo looks through them, remembering a file found not there so one that really isn't costs the wait once. A magpie started by an update now waits for the one it replaces before its start-up moves write any file (AwaitPredecessor at the top of run, not only in the GUI). TestLoginsKeptWhileAnotherMagpieWrites (Windows: two writers replacing logins.json, readLogins never without the Antigravity account) failed 1 in 3 and 2 in 8 runs on the old code ("read as no accounts 8 times"), passed 11 of 11 on this; filememo's TestReadWhileReplaced the same (1180 misses on the old code); TestStatWaitsOutAReplace everywhere. A real update in a sandbox home on the Windows box, magpie-cli 0.1.880 → 0.1.942 from the release, kept the account and logins.json byte for byte. go vet (darwin, and windows nogui), builds (darwin, GOOS=linux nogui, GOOS=windows) and go test -tags nogui -count=1 ./... under a temp HOME pass.

filememo_test.go

perf: magpie opens and shows the Agents page in a fraction of the time it took (Junjie Zhou on Discord: 8 个 agent 30 个 provider … 每次我打开的时候都会很慢，要好几秒。setting 页面秒进后 我切换到 agent 就有问题) — at start, writing the agents' model lists (agent.SyncCatalog) built every provider's catalog thousands of times with nothing held, each build reading migrations.json, settings and groups again: 6000+ file reads and ~8.5s of CPU in the first 8s with the owner's 30-odd providers, all competing with the first /api/state and the Agents page. Now SyncCatalog, magpieModels and main's start-up moves run under provider.Hold, migrations, groups, settings and a provider's fetched models are held for a second like the rest, and filememo.Hold lets a GET /api/* not stat a file it confirmed unchanged within the last second (any magpie write, Changed() or a recent mtime still reads it again). A big ~/.codex/config.toml parsed in quadratic time (the TOML parser's Shape counts newlines from the start for every key): a 3 MB one took 5.4s, now 0.04s (tomlShaper). theInstalled reads through edit.Read's memo. Measured with a copy of the owner's magpie config and agent configs under a sandbox HOME, the real server in WebKit: CPU in the first 8s 8.59s → 0.39s, page up 475 → 75ms, Agents rows drawn 775 → 325ms after start; the agents' written model files are unchanged (pi byte for byte, opencode the same models). TestTOMLShaperMatchesParser, TestTOMLBigFileParsesInLinearTime (fails on the old code), TestHold (filememo), TestHoldReadsMigrationsOnce. go vet, builds (darwin, GOOS=linux nogui, GOOS=windows) and go test -tags nogui ./... under a temp HOME pass.
