pm2 7.1.0

v7.1.0

on Node.js NPM

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
