v0.13.0

Breaking changes

This release has several breaking API changes you should be aware of:

• MSRV has been changed from 1.34 to 1.48
• The Process struct has been changed in some important ways:
  • Internally, it now maintains a handle to an opened /proc/<pid> directory. So each Process will have an open file handle, which can matter in extreme cases when you have a large number of Process objects created.
  • Because each Process has a handle to its opened proc directory, there is no longer any PID reuse problems (that is, there is no risk of accidentally getting process information for a new process that has reused a PID)
  • Process no longer implements Clone.
  • Process no longer has a public member stats member that gets pre-populated on construction. If you want this info, you now need to explicitly call the Process::stat() function

New features

• Revive RFC: Change Process to use directory fd by @sunfishcode in #171
• Add support for /proc/<pid>/pagemap by @EliaGeretto in #166
• Process: Add support for network by @arilou in #176

Internal changes

• Add build-script to provide a nicely readable error if on unsupported platform by @macisamuele in #167
• Fix a race condition in the test_task_runsinglethread test. by @sunfishcode in #169
• Bump MSRV to 1.42 by @eminence in #170
• Update github-actions configuration to run all the github actions up to completion by @macisamuele in #172
• Improve CpuInfo performances by @macisamuele in #168
• Build with cargo update -Z minimal-versions by @xfix in #173
• Update to the latest rustix version by @eminence in #174
• Clippy and rustfmt fixes by @eminence in #175

Full Changelog: v0.12.0...v0.13.0

v0.12.0

Breaking changes

• Make the flate2 dependency optional by @eminence in #157

The flate2 dependencies was used only in the kernel_config method, which would try to read a compressed /proc/config.gz file if it existed. The flate2 dependency is now optional (and enabled by default). If you are using procfs with "default-features = false" and you are using the kernel_config method, pay special attention here -- you might want to manually enable the flate2 feature.

New features

• /proc/sysvipc/shm by @tatref in #154
• Add support for /proc/net/route by @pymongo in #162
• Add support for /proc/sys/kernel/{ostype,version} by @KernelErr in #163

Bug fixes

• fix: 32bit signed int by @tatref in #153

Full Changelog: v0.11.0...v0.12.0

v0.11.1

Bug fixes

• fix: 32bit signed int by @tatref in #153

v0.11.0

Breaking changes

• Switch to u64 from usize in many places by @h33p in #147
  • On 64-bit machines, this change should have no impact on behavior, but it is still a breaking change as these types are part of the public API.
• Remove unwraps from our lazy statics by @eminence in #150
  • This change should make procfs panic even less, but as the cost of a breaking API change that wraps the return value of some functions in a Result

New Features

• Update docs and CI for MSRV by @eminence in #149
• Add support for /proc/uptime by @oblique in #146
• MMapPath::Vsys for /SYSV pseudo files by @tatref in #151
