v1.5.0

v1.5.0 Release

This release introduces comprehensive pdsh compatibility mode, hostlist expressions, and TUI improvements.

New Features

• pdsh Compatibility Mode (Issues #100-103, #105, #107, #110)

  • Full pdsh-style command line compatibility when invoked as pdsh or with --pdsh-compat
  • -w hosts option mapped to -H hosts for target host specification
  • -x hosts option mapped to --exclude hosts for host exclusion
  • -f N option mapped to --parallel N for fanout control
  • -l user option for remote username
  • -t N option mapped to --connect-timeout N for connection timeout
  • -u N option mapped to --timeout N for command timeout
  • -N option mapped to --no-prefix for disabling hostname prefix in output
  • -b option mapped to --batch for single Ctrl+C termination
  • -k option mapped to --fail-fast for stop on first failure
  • -q query mode to show target hosts and exit
  • -S option mapped to --any-failure for returning largest exit code

• Hostlist Expressions (Issue #107)

  • pdsh-style range expansion: node[1-5] → node1, node2, node3, node4, node5
  • Zero-padded ranges: node[01-05] → node01, node02, node03, node04, node05
  • Comma-separated values: node[1,3,5] → node1, node3, node5
  • Cartesian product: rack[1-2]-node[1-3] → 6 hosts
  • Domain suffix support: web[1-3].example.com
  • User and port preservation: admin@db[01-03]:5432
  • File input with ^/path/to/hostfile

• In-TUI Log Panel (Issue #106)

  • Toggle visibility with l key
  • Color-coded by level: ERROR (red), WARN (yellow), INFO (white), DEBUG (gray)
  • Configurable buffer size via BSSH_TUI_LOG_MAX_ENTRIES (default: 1000, max: 10000)
  • Panel height adjustable from 3-10 lines with +/- keys
  • Scroll with j/k keys, toggle timestamps with t

• --fail-fast Option (Issue #103)

  • -k / --fail-fast flag to stop immediately on first failure
  • Compatible with pdsh -k option
  • Cancels pending commands when any node fails
  • Can be combined with --require-all-success for strict error handling

• --batch Option (Issue #102)

  • -b / --batch flag for single Ctrl+C termination
  • Compatible with pdsh -b option
  • Useful for non-interactive scripts and CI/CD pipelines

• --exclude Option (Issue #100)

  • --exclude / -x for host exclusion
  • Supports wildcards, glob patterns, and hostlist expressions
  • Applied after --filter option

• --no-prefix Option (Issue #101)

  • -N / --no-prefix for disabling hostname prefix in output
  • Compatible with pdsh -N option
  • Works with both stream mode and file mode

• --connect-timeout Option

  • Separate connection timeout from command execution timeout
  • Default: 30 seconds, minimum: 1 second
  • Useful for fast failure detection on unreachable hosts

Improvements

• CI workflow simplification by merging jobs into single pipeline

Bug Fixes

• --timeout 0 Handling (Issue #112)

  • Fixed --timeout 0 to correctly treat as unlimited execution time
  • Previously the 0 value was being ignored, causing unexpected timeout behavior
  • Added explicit CLI test to prevent regression

• Environment Variable Test Race Conditions

  • Added #[serial] attribute to env var tests to prevent race conditions
  • Tests now run sequentially when accessing shared environment state

• Connect Timeout Propagation

  • Fixed connect_timeout not being propagated through all SSH connection paths

CI/CD Improvements

• Simplified CI workflow by merging multiple jobs into single pipeline

Technical Details

• pdsh compatibility layer core infrastructure
• Comprehensive hostlist expression parser with cartesian product support
• Added explicit CLI test for --timeout 0 behavior
