# ps 1.8.1
|
|
|
|
* ps can now be installed again on unsupported platforms.
|
|
|
|
# ps 1.8.0
|
|
|
|
* New `ps_apps()` function to list all running applications on macOS.
|
|
|
|
* New function `ps_disk_io_counters()` to query disk I/O counters
|
|
(#145, @michaelwalshe).
|
|
|
|
* New `ps_fs_info()` to query information about the file system of one
|
|
or more files or directories.
|
|
|
|
* New `ps_wait()` to start an interruptible wait on multiple processes,
|
|
with a timeout (#166).
|
|
|
|
* `ps_handle()` now allows a numeric (double) scalar as the pid, as long
|
|
as its value is integer.
|
|
|
|
* `ps_send_signal()`, `ps_suspend()`, `ps_resume()`, `ps_terminate()`,
|
|
`ps_kill()`, and `ps_interrupt()` can now operate on multiple processes,
|
|
if passed a list of process handles.
|
|
|
|
* `ps_kill()` and `ps_kill_tree()` have a new `grace` argument.
|
|
On Unix, if this argument is not zero, then `ps_kill()` first sends a
|
|
`TERM` signal, and waits for the processes to quit gracefully, via
|
|
`ps_wait()`. The processes that are still alive after the grace period
|
|
are then killed with `SIGKILL`.
|
|
|
|
* `ps_status()` (and thus `ps()`) is now better at getting the correct
|
|
status of processes on macOS. This usually requires calling the external
|
|
`ps` tool. See `?ps_status()` on how to opt out from the new
|
|
behavior (#31).
|
|
|
|
# ps 1.7.7
|
|
|
|
* `ps_cpu_times()` values are now correct on newer arm64 macOS.
|
|
|
|
# ps 1.7.6
|
|
|
|
* `ps_name()` now does not fail in the rare case when `ps_cmdline()` returns an empty vector (#150).
|
|
|
|
* `ps_system_cpu_times()` now returns CPU times divided by the HZ as reported by CLK_TCK, in-line with other OS's and the per-process version. (#144, @michaelwalshe).
|
|
|
|
# ps 1.7.5
|
|
|
|
No user visible changes.
|
|
|
|
# ps 1.7.4
|
|
|
|
* `ps::ps_get_cpu_affinity()` now works for other processes on Linux, not only
|
|
the calling process.
|
|
|
|
# ps 1.7.3
|
|
|
|
* The output of `ps_disk_usage()`, `ps_disk_partitions()` and
|
|
`ps_shared_lib_users()` now do not include a spurious `stringsAsFactors`
|
|
column.
|
|
|
|
# ps 1.7.2
|
|
|
|
* `ps_system_memory()$percent` now returns a number scaled between 0 and 100
|
|
on Windows, rather than between 0 and 1 (#131, @francisbarton).
|
|
|
|
# ps 1.7.1
|
|
|
|
* ps now returns data frames instead of tibbles. While data frames and
|
|
tibbles are very similar, they are not completely compatible. To convert
|
|
the output of ps to tibbles call the `tibble::as_tibble()` function
|
|
on them.
|
|
|
|
* `ps()` now does not fail if both `user` and `after` are specified (#129).
|
|
|
|
# ps 1.7.0
|
|
|
|
* ps now compiles on platforms that enable OpenMP (#109).
|
|
|
|
* New functions `ps_get_cpu_affinity()` and `ps_set_cpu_affinity()` to query
|
|
and set CPU affinity (#123).
|
|
|
|
* `ps_memory_info()` now does not mix up `rss` and `vms` on Linux.
|
|
|
|
* `ps_memory_info()` now reports memory in bytes instead of pages on Linux (#115)
|
|
|
|
# ps 1.6.0
|
|
|
|
* New function `ps_system_cpu_times()` to calculate system CPU times.
|
|
|
|
* New function `ps_loadavg()` to show the Unix style load average.
|
|
|
|
# ps 1.5.0
|
|
|
|
* New function `ps_shared_libs()` to list the loaded shared libraries
|
|
of a process, on Windows.
|
|
|
|
* New function `ps_shared_lib_users()` to list all processes that
|
|
loaded a certain shared library, on Windows.
|
|
|
|
* New function `ps_descent()` to query the ancestry of a process.
|
|
|
|
# ps 1.4.0
|
|
|
|
* ps is now under the MIT license.
|
|
|
|
* Process functions now default to the calling R process. So e.g. you can
|
|
write simply `ps_connections()` to list all network connections of the
|
|
current process, instead of `ps_connections(ps_handle())`.
|
|
|
|
* New `ps_get_nice()` and `ps_set_nice()` functions to get and set the
|
|
priority of a process (#89).
|
|
|
|
* New `ps_system_memory()` and `ps_system_swap()` functions, to
|
|
return information about system memory and swap usage.
|
|
|
|
* New `ps_disk_partitions()` and `ps_disk_usage()` functions, they
|
|
return information about file systems, similarly to the `mount` and
|
|
`df` Unix commands.
|
|
|
|
* New `ps_tty_size()` function to query the size of the terminal.
|
|
|
|
* Fixed an issue in `CleanupReporter()` that triggered random failures
|
|
on macOS.
|
|
|
|
# ps 1.3.4
|
|
|
|
* `ps_cpu_count()` now reports the correct number on Windows, even if
|
|
the package binary was built on a Windows version with a different
|
|
API (#77).
|
|
|
|
# ps 1.3.3
|
|
|
|
* New function `errno()` returns a table of `errno.h` error codes and
|
|
their description.
|
|
|
|
* ps now compiles again on Solaris.
|
|
|
|
# ps 1.3.2
|
|
|
|
* ps now compiles again on unsupported platforms like Solaris.
|
|
|
|
# ps 1.3.1
|
|
|
|
* Fixed an installation problem on some Windows versions, where the
|
|
output of `cmd /c ver` looks different (#69).
|
|
|
|
# ps 1.3.0
|
|
|
|
* New `ps_cpu_count()` function returns the number of logical or
|
|
physical processors.
|
|
|
|
# ps 1.2.1
|
|
|
|
* Fix a crash on Linux, that happened at load time (#50).
|
|
|
|
# ps 1.2.0
|
|
|
|
* New `ps_connections()` to list network connections. The
|
|
`CleanupReporter()` testthat reporter can check for leftover open
|
|
network connections in test cases.
|
|
|
|
* `ps_open_files()` does not include open sockets now on Linux, they are
|
|
rather included in `ps_connections()`.
|
|
|
|
* `CleanupReporter()` now ignores `/dev/urandom`, some packages (curl,
|
|
openssl, etc.) keep this file open.
|
|
|
|
* Fix `ps()` printing without the tibble package (#43).
|
|
|
|
* Fix compilation with ICC (#39).
|
|
|
|
* Fix a crash on Linux (#47).
|
|
|
|
# ps 1.1.0
|
|
|
|
* New `ps_num_fds()` returns the number of open files/handles.
|
|
|
|
* New `ps_open_files()` lists all open files of a process.
|
|
|
|
* New `ps_interrupt()` interrupts a process. It sends a `SIGINT` signal on
|
|
POSIX systems, and it can send CTRL+C or CTRL+BREAK events on Windows.
|
|
|
|
* New `ps_users()` lists users connected to the system.
|
|
|
|
* New `ps_mark_tree()`, `ps_find_tree()`, `ps_kill_tree()`,
|
|
`with_process_cleanup()`: functions to mark and clean up child
|
|
processes.
|
|
|
|
* New `CleanupReporter`, to be used with testthat: it checks for
|
|
leftover child processes and open files in `test_that()` blocks.
|
|
|
