PM2 Files

7.1.0

Features

• pm2 monit / pm2 dash now preload the last 200 lines (out + err merged) of every process from its log files, most recent first; --lines <n> to display more [#5187]
• pm2 monit: Ctrl+Up / Ctrl+Down (and PageUp / PageDown) scroll the focused log pane page by page

Bug Fixes

• Shell environment variables named like a PM2 option (name, namespace, cron_restart, instances...) no longer override the app configuration [#6006] [#6016] [#5747] [#5622] [#5030] [#5032] [#4943] [#4778] [#4821] [#3210]
• Variables declared in env: and named like a PM2 option (env: { port: 3000 }, time, watch...) still reach the app: only the ambient shell environment is filtered, not what the user declares
• Cluster mode: the pid list of the previous kill (_tree_pids, since 7.0.0) no longer leaks into the app's process.env after a restart, nor gets reused as the pid list of a later kill
• pm2 monit: align the Custom Metrics pane in columns (value right-aligned, fixed unit column, numbers rounded to 2 decimals) and shorten long metric names instead of pushing values out of the pane
• pm2 monit: the footer no longer overlaps the bottom border of the Custom Metrics / Metadata panes
• pm2 monit: logs, metrics and metadata panes update instantly when the selected process changes (no longer wait for the next refresh tick)
• pm2 monit: characters of old log lines no longer stay stuck on screen — emoji are now measured as 2 cells, and \r, cursor escape sequences, control chars and {tags} in logs are sanitized [#5397]
• @pm2/blessed is now vendored in modules/blessed (one less npm dependency)
• chokidar 3.6.0 is now vendored in modules/chokidar with a bounded brace expansion, dropping the vulnerable braces dependency (GHSA-vfj7-8cjw-p6xm, no patched version)
• Logs: no more lost lines in fork mode with --time / log_date_format when an app writes more than 64KB at once (partial line at a pipe chunk boundary was dropped) [#6125]
• Logs: in cluster mode with --time, every line of a multi-line write is now date-prefixed (not only the first)
• pm2 logs "/regex/" --lines 0 now streams matching apps (regex was ignored in stream-only mode); regexes with an inner / are no longer mangled, apps started after pm2 logs are picked up, and only one bus subscription is opened [#5196]
• pm2 reloadLogs no longer crashes the app in fork mode when out_file/error_file are NULL and only log_file is set [#5509]
• Logs: log streams are now flushed (end()) instead of destroyed on pm2 reloadLogs / app exit, so buffered data is no longer truncated
• pm2 serve: a request with a malformed percent-escape (GET /%) no longer crashes the server (answers 400); handler exceptions answer 500 instead of killing the process
• Logs: in cluster mode, output that bypasses process.stdout.write (pino/sonic-boom, npm start, children spawned with stdio inherit) no longer ends up in pm2.log — workers get piped stdio and the daemon routes it to the app log files and pm2 logs [#3675] [#4719] [#4872] [#4916] [#4953] [#5633] [#4816]
• Logs: in cluster mode, the worker's stdout/stderr pipes are made blocking so a raw write bigger than the pipe buffer (fs.writeSync(1, ...), native addons) is no longer silently truncated at 64 KB [#4044] [#4872]
• exec_mode: cluster on a non Node.js/Bun script (bash, python, binary) now falls back to fork mode with a warning instead of crashing with SyntaxError: Invalid or unexpected token (ELF) [#4775]
• Node.js/Bun interpreter detection now accepts atypical binary names (node.exe, node64.exe, nodejs, node18, node@18, bun.exe), so cluster mode and the fork-mode wrapper are no longer skipped for them
• Restart/stop on systems without ps (slim Docker images) no longer starts the app twice and crashes the daemon with Callback was already called [#6171]
• TreeKill: no ps under Bun (synchronous spawn throw) falls back to killing the root pid
• An online process without a pid (e.g. failed spawn) no longer makes pidusage fail for every app (One of the pids provided is invalid spam) [#6134] [#6135]
• Cluster mode with uid/gid: log files created by a root daemon are chowned to the app user (no more EACCES crash loop)
• pm2 reloadLogs no longer crashes the daemon (ERR_IPC_CHANNEL_CLOSED) nor leaks fds when a cluster app is stopped, nor on concurrent calls
• Explicit exec_mode: cluster is kept for JS/TS apps run by a custom interpreter (tsx, ts-node); fork fallback only for binaries and non-JS scripts/interpreters [#4775]
• pm2 serve: null bytes answer 400 (--spa no longer crashes on GET /x/%2500), errors in async file handlers answer 500
• Fork/cluster: log files are closed once the app stdout/stderr pipes are closed, no longer on the ChildProcess close that sometimes never comes on Linux (2 fds leaked per app stop/restart/delete)
• Stale _tree_pids from a 7.0.0-7.0.4 dump no longer leaks into the app env nor gets an unrelated pid SIGKILLed on stop
• PM2.io agent: PM2_PROXY support removed with the proxy-agent dependency (unused, broken since 7.0.0 with ProxyAgent is not a constructor; drops the vulnerable get-uri/basic-ftp chain)
• Behavior change: shell variables named like a PM2 option (port, time, watch...) are no longer forwarded to fork mode apps; declare them in env:
• pm2 ls host metrics: virtual interfaces and read-only mounts are hidden
