# Change Log
All notable changes to this project will be documented in this file.
This project adheres to [Semantic Versioning](http://semver.org/).
## [Unreleased]
### Added
### Fixed
### Changed
### Deprecated
## [0.8.0]
### Added
- Added partial `getrusage` support for Windows to retrieve system CPU time and user CPU time. #95
- Added full `getrusage` support for Unix. #95
## [0.7.0]
### Added
- Added method stubs for process handling for operating system that are not supported
by gosigar. All methods return `ErrNotImplemented` on such systems. #88
### Fixed
- Fix freebsd build by using the common version of Get(pid). #91
### Changed
- Fixed issues in cgroup package by adding missing error checks and closing
file handles. #92
## [0.6.0]
### Added
- Added method stubs to enable compilation for operating systems that are not
supported by gosigar. All methods return `ErrNotImplemented` on these unsupported
operating systems. #83
- FreeBSD returns `ErrNotImplemented` for `ProcTime.Get`. #83
### Changed
- OpenBSD returns `ErrNotImplemented` for `ProcTime.Get` instead of `nil`. #83
- Fixed incorrect `Mem.Used` calculation under linux. #82
- Fixed `ProcState` on Linux and FreeBSD when process names contain parentheses. #81
### Removed
- Remove NetBSD build from sigar_unix.go as it is not supported by gosigar. #83
## [0.5.0]
### Changed
- Fixed Trim environment variables when comparing values in the test suite. #79
- Make `kern_procargs` more robust under darwin when we cannot retrieve
all the information about a process. #78
## [0.4.0]
### Changed
- Fixed Windows issue that caused a hang during `init()` if WMI wasn't ready. #74
## [0.3.0]
### Added
- Read `MemAvailable` value for kernel 3.14+ #71
## [0.2.0]
### Added
- Added `ErrCgroupsMissing` to indicate that /proc/cgroups is missing which is
an indicator that cgroups were disabled at compile time. #64
### Changed
- Changed `cgroup.SupportedSubsystems()` to honor the "enabled" column in the
/proc/cgroups file. #64
## [0.1.0]
### Added
- Added `CpuList` implementation for Windows that returns CPU timing information
on a per CPU basis. #55
- Added `Uptime` implementation for Windows. #55
- Added `Swap` implementation for Windows based on page file metrics. #55
- Added support to `github.com/gosigar/sys/windows` for querying and enabling
privileges in a process token.
- Added utility code for interfacing with linux NETLINK_INET_DIAG. #60
- Added `ProcEnv` for getting a process's environment variables. #61
### Changed
- Changed several `OpenProcess` calls on Windows to request the lowest possible
access privileges. #50
- Removed cgo usage from Windows code.
- Added OS version checks to `ProcArgs.Get` on Windows because the
`Win32_Process` WMI query is not available prior to Windows vista. On XP and
Windows 2003, this method returns `ErrNotImplemented`. #55
### Fixed
- Fixed value of `Mem.ActualFree` and `Mem.ActualUsed` on Windows. #49
- Fixed `ProcTime.StartTime` on Windows to report value in milliseconds since
Unix epoch. #51
- Fixed `ProcStatus.PPID` value is wrong on Windows. #55
- Fixed `ProcStatus.Username` error on Windows XP #56

# Go sigar [![Build Status](https://travis-ci.org/elastic/gosigar.svg?branch=master)](https://travis-ci.org/elastic/gosigar) [![Build status](https://ci.appveyor.com/api/projects/status/4yh6sa7u97ek5uib/branch/master?svg=true)](https://ci.appveyor.com/project/elastic-beats/gosigar/branch/master)
## Overview
Go sigar is a golang implementation of the
[sigar API](https://github.com/hyperic/sigar). The Go version of
sigar has a very similar interface, but is being written from scratch
in pure go/cgo, rather than cgo bindings for libsigar.
## Test drive
$ go get github.com/elastic/gosigar
$ cd $GOPATH/src/github.com/elastic/gosigar/examples/ps
$ go build
$ ./ps
## Supported platforms
The features vary by operating system.
| Feature | Linux | Darwin | Windows | OpenBSD | FreeBSD |
|-----------------|:-----:|:------:|:-------:|:-------:|:-------:|
| Cpu | X | X | X | X | X |
| CpuList | X | X | | X | X |
| FDUsage | X | | | | X |
| FileSystemList | X | X | X | X | X |
| FileSystemUsage | X | X | X | X | X |
| LoadAverage | X | X | | X | X |
| Mem | X | X | X | X | X |
| ProcArgs | X | X | X | | X |
| ProcEnv | X | X | | | X |
| ProcExe | X | X | | | X |
| ProcFDUsage | X | | | | X |
| ProcList | X | X | X | | X |
| ProcMem | X | X | X | | X |
| ProcState | X | X | X | | X |
| ProcTime | X | X | X | | X |
| Swap | X | X | | X | X |
| Uptime | X | X | | X | X |
## OS Specific Notes
### FreeBSD
Mount both `linprocfs` and `procfs` for compatability. Consider adding these
mounts to your `/etc/fstab` file so they are mounted automatically at boot.
```
sudo mount -t procfs proc /proc
sudo mkdir -p /compat/linux/proc
sudo mount -t linprocfs /dev/null /compat/linux/proc
```

# Version 1.x.x
* **Add more test cases and reference new test COM server project.** (Placeholder for future additions)
# Version 1.2.0-alphaX
**Minimum supported version is now Go 1.4. Go 1.1 support is deprecated, but should still build.**
* Added CI configuration for Travis-CI and AppVeyor.
* Added test InterfaceID and ClassID for the COM Test Server project.
* Added more inline documentation (#83).
* Added IEnumVARIANT implementation (#88).
* Added IEnumVARIANT test cases (#99, #100, #101).
* Added support for retrieving `time.Time` from VARIANT (#92).
* Added test case for IUnknown (#64).
* Added test case for IDispatch (#64).
* Added test cases for scalar variants (#64, #76).
# Version 1.1.1
* Fixes for Linux build.
* Fixes for Windows build.
# Version 1.1.0
The change to provide building on all platforms is a new feature. The increase in minor version reflects that and allows those who wish to stay on 1.0.x to continue to do so. Support for 1.0.x will be limited to bug fixes.
* Move GUID out of variables.go into its own file to make new documentation available.
* Move OleError out of ole.go into its own file to make new documentation available.
* Add documentation to utility functions.
* Add documentation to variant receiver functions.
* Add documentation to ole structures.
* Make variant available to other systems outside of Windows.
* Make OLE structures available to other systems outside of Windows.
## New Features
* Library should now be built on all platforms supported by Go. Library will NOOP on any platform that is not Windows.
* More functions are now documented and available on godoc.org.
# Version 1.0.1
1. Fix package references from repository location change.
# Version 1.0.0
This version is stable enough for use. The COM API is still incomplete, but provides enough functionality for accessing COM servers using IDispatch interface.
There is no changelog for this version. Check commits for history.

#Go OLE
[![Build status](https://ci.appveyor.com/api/projects/status/qr0u2sf7q43us9fj?svg=true)](https://ci.appveyor.com/project/jacobsantos/go-ole-jgs28)
[![Build Status](https://travis-ci.org/go-ole/go-ole.svg?branch=master)](https://travis-ci.org/go-ole/go-ole)
[![GoDoc](https://godoc.org/github.com/go-ole/go-ole?status.svg)](https://godoc.org/github.com/go-ole/go-ole)
Go bindings for Windows COM using shared libraries instead of cgo.
By Yasuhiro Matsumoto.
## Install
To experiment with go-ole, you can just compile and run the example program:
```
go get github.com/go-ole/go-ole
cd /path/to/go-ole/
go test
cd /path/to/go-ole/example/excel
go run excel.go
```
## Continuous Integration
Continuous integration configuration has been added for both Travis-CI and AppVeyor. You will have to add these to your own account for your fork in order for it to run.
**Travis-CI**
Travis-CI was added to check builds on Linux to ensure that `go get` works when cross building. Currently, Travis-CI is not used to test cross-building, but this may be changed in the future. It is also not currently possible to test the library on Linux, since COM API is specific to Windows and it is not currently possible to run a COM server on Linux or even connect to a remote COM server.
**AppVeyor**
AppVeyor is used to build on Windows using the (in-development) test COM server. It is currently only used to test the build and ensure that the code works on Windows. It will be used to register a COM server and then run the test cases based on the test COM server.
The tests currently do run and do pass and this should be maintained with commits.
##Versioning
Go OLE uses [semantic versioning](http://semver.org) for version numbers, which is similar to the version contract of the Go language. Which means that the major version will always maintain backwards compatibility with minor versions. Minor versions will only add new additions and changes. Fixes will always be in patch.
This contract should allow you to upgrade to new minor and patch versions without breakage or modifications to your existing code. Leave a ticket, if there is breakage, so that it could be fixed.
