CHANGELOG.md - third_party/Masterminds/glide - Git at Google

 # Release 0.12.2 (2016-09-13)

 ## Fixed
 - #599: In some cases was not importing dependencies config
 - #601: Fixed issue where --all-dependencies flag stopped working

 # Release 0.12.1 (2016-08-31)

 ## Fixed
 - #578: Not resolving parent project packages in some cases
 - #580: cross-device error handling failed on Windows in some cases
 - #590: When exit signal received remove global lock

 Note, Plan 9 is an experimental OS for Go. Due to some issues we are not going
 to be supporting builds for it at this time.

 # Release 0.12.0 (2016-08-23)

 ## Added
 - Support for distributions in FreeBSD, OpenBSD, NetBSD, and Plan9
 - #528: ARM release support (thanks @franciscocpg)
 - #563: Added initial integration testing

   path list separators being used.
 - Fixed #185 and #187: Inaccurate hash being generated for lock file with nested
   version ranges.
 - Fixed #182 and #183: Caching on go-import lookups mishandled some prefixes.

   runtime than compile time.
 - Fixed #165: glide update panics with --no-recursive option.
 - Added back zip build option to build scripts. This is useful for some
   environments.

 # Release 0.8.0 (2015-12-10)

 - Issues #156 and #85: Added lockfile support (glide.lock). This file records
   commit id pinned versions of the entire dependency tree. The `glide install`
   command installs the pinned dependencies from the `glide.lock` file while
   `glide update` updates the tree and lockfile. Most people should use `glide
   install` unless they want to intentionally updated the pinned dependencies.
   `glide install` is able to use concurrency to more quickly install update.
 - Issues #33 and #159: Glide notifies if a dependency checkout has uncomitted
   changes.
 - Issue #146: Glide scans projects not managed by a dependency manager, fetches
   their dependencies, and pins them in the glide.lock file.
 - Issue #99: Glide `get` pins dependencies by default and allows a version to
   be passed in. For example, `glide get github.com/Masterminds/convert#^1.0.0`
   will fetch `github.com/Masterminds/convert` with a version of `^1.0.0`.

 - Issue #126: Added --no-color option to remove color for systems that do not
   work well with color codes (thanks albrow).
 - Added caching functionality (some opt-in).
 - Added global debug flag.
 - Moved yaml parsing and writing to gopkg.in/yaml.v2 and separated
   config handling into separate package.
 - Better godep import handling.
 - Fixed #98: Godep command name fix (thanks jonboulle).
 - #52 and #114: Add semantic version (SemVer) support.

 - Fixed #95: Added more detail for errors previously reporting "Oops! exit
   status 128".
 - Fixed #86 and #71: Imported package names including a sub-package were checked
   out to the wrong location. They are not checked out to the right place and
   multiple instances of the top level repo are merged with error checking.

 # Release 0.6.1 (2015-09-21)

 - Fixed #82: C was not recognized as an internal package.
 - Fixed #84: novendor (nv) command returned directories with no Go code.

   incorrect (thanks janeczku).

   vendored directories.

 **Glide .5 is a major update breaking some backwards compatability with
 previous releases.**

 - Migrated to using the vendor/ directory and the go tools for vendor
   package management. To leverage this you'll need to set the
   environment variable GO15VENDOREXPERIMENT=1 and use Go 1.5.
 - `glide up` is now recursive and walks installed packages if there is
   no vendor directory. Use the --no-recursive flag to skip this.
 - Removed GOPATH management. This was needed for vendor package
   management that's not built into the go toolchain.
 - Switched to github.com/Masterminds/vcs for VCS integration.
 - When updating packages are now deleted if the --delete flag is set.
   This feature is now opt-in.

   one. (via roblillack)

   system's PATH (via jarod).
 - Issue #28: Use HTTPS instead of HTTP for git and hg. (Thanks chendo)
 - Issue #26: 'glide gopath' is smarter. It now looks for glide.yaml.
 - Issue #24: Trim whitespace off of package names. (Thanks roblillack)

 # Release 0.2.0 (2014-10-03)

   repo. (HUGE thanks to dz0ny)

	# Release 0.8.3 (2015-12-30)

	- Issue #198: Instead of stopping `glide install` for a hash failures providing
	a warning. Failed hash check is currently too aggressive.
	- Fixed #199: `glide up` on Windows unable to detect dependencies when GOPATH
	and GOROOT on a different drive or when GOROOT ends in a path separator.
	- Fixed #194: `glide up` stalling on Windows due to POSIX path separators and
	path list separators being used.
	- Fixed #185 and #187: Inaccurate hash being generated for lock file with nested
	version ranges.
	- Fixed #182 and #183: Caching on go-import lookups mishandled some prefixes.
	- Fixed issue in deduping and sub-package names.
	- Fixed #189: nested dependencies that do not contain VCS information were not
	being updated properly when --updated-vendored was being used.

	# Release 0.8.2 (2015-12-21)

	- Fixed #169: cookoo git url has auth info. Makes glide unbuildable for
	environments not setup for GitHub.

	environments.

	# Release 0.8.0 (2015-12-10)

	- Issues #156 and #85: Added lockfile support (glide.lock). This file records
	commit id pinned versions of the entire dependency tree. The `glide install`
	command installs the pinned dependencies from the `glide.lock` file while
	`glide update` updates the tree and lockfile. Most people should use `glide
	install` unless they want to intentionally updated the pinned dependencies.
	`glide install` is able to use concurrency to more quickly install update.
	- Issues #33 and #159: Glide notifies if a dependency checkout has uncomitted
	changes.
	- Issue #146: Glide scans projects not managed by a dependency manager, fetches
	their dependencies, and pins them in the glide.lock file.
	- Issue #99: Glide `get` pins dependencies by default and allows a version to
	be passed in. For example, `glide get github.com/Masterminds/convert#^1.0.0`
	will fetch `github.com/Masterminds/convert` with a version of `^1.0.0`.
	- Issue #155: Copying packages from the `GOPATH` is now opt-in.

	config handling into separate package.

	- Fixed #95: Added more detail for errors previously reporting "Oops! exit
	status 128".
	- Fixed #86 and #71: Imported package names including a sub-package were checked
	out to the wrong location. They are not checked out to the right place and
	multiple instances of the top level repo are merged with error checking.

	# Release 0.6.1 (2015-09-21)

	- Fixed #82: C was not recognized as an internal package.

	vendored directories.
	- Fixed #68: Handling the base where the GOPATH has multiple separated directories.

	# Release 0.5.0 (2015-08-19)

	**Glide .5 is a major update breaking some backwards compatability with
	previous releases.**

	- Migrated to using the vendor/ directory and the go tools for vendor
	package management. To leverage this you'll need to set the
	environment variable GO15VENDOREXPERIMENT=1 and use Go 1.5.
	- `glide up` is now recursive and walks installed packages if there is
	no vendor directory. Use the --no-recursive flag to skip this.

	management that's not built into the go toolchain.
	- Switched to github.com/Masterminds/vcs for VCS integration.
	- When updating packages are now deleted if the --delete flag is set.
	This feature is now opt-in.
