示例1: lock
(async () => {
const release = await lock('some/file'); // $ExpectType () => Promise<void>
await release(); // $ExpectType void
await lock('some/file'); // $ExpectType () => Promise<void>
await unlock('some/file'); // $ExpectType void
await check('some/file'); // $ExpectType boolean
})();示例2: runInit
public async runInit(force: boolean) {
if (this.repoConfig.init) {
const versionFile = path.join(this.workspaceDir, 'init.version');
if (this.checkRevision(versionFile) && !force) {
this.log.info('a same revision exists, init cmd skipped.');
return;
}
const lockFile = this.workspaceDir; // path.join(this.workspaceDir, 'init.lock');
const isLocked = await LockFile.check(lockFile);
if (isLocked) {
this.log.info('another process is running, please try again later');
return;
}
const release = await LockFile.lock(lockFile);
try {
const process = this.spawnProcess(this.repoConfig.init);
const logFile = path.join(this.workspaceDir, 'init.log');
const logFileStream = fs.createWriteStream(logFile, { encoding: 'utf-8', flags: 'a+' });

this.redirectOutput(process.stderr, logFileStream, true);
process.on('close', async (code, signal) => {
logFileStream.close();
await this.writeRevisionFile(versionFile);
this.log.info(`init process finished with code: ${code} signal: ${signal}`);
await release();
});
} catch (e) {
