* removed packer.Cache and references since packer.Cache is never used except in the download step. The download step now uses the new func packer.CachePath(targetPath) for this, the behavior is the same.
* removed download code from packer that was reimplemented into the go-getter library: progress bar, http download restart, checksuming from file, skip already downloaded files, symlinking, make a download cancellable by context.
* on windows if packer is running without symlinking rights and we are getting a local file, the file will be copied instead to avoid errors.
* added unit tests for step_download that are now CI tested on windows, mac & linux.
* files are now downloaded under cache dir `sha1(filename + "?checksum=" + checksum) + file_extension`
* since the output dir is based on the source url and the checksum, when the checksum fails, the file is auto deleted.
* a download file is protected and locked by a file lock,
* updated docs
* updated go modules and vendors
* simplified the downloader interface, and removed the total/current values from them
* downloaders use a proxy reader that will add all read bytes to progress
* removed unused const mtu
* DownloadClient doesn't need a downloader, so I removed it too
common/config.go:
Added the ability for DownloadableURL to promote UNC paths to the SMB uri.
Modified DownloadableURL to include the "./" prefix when a relative path is passed to it.
Fix-up the DownloadableURL argument if on windows and incorrectly prefixed with "/".
config.go:
Fixed some issues related to the url scheme not being lowercased which broke some of the tests.
config_test.go:
Removed the UNC share test for \\host\share\file since SMB support has been moved to a different uri scheme.
download_test.go:
Explicitly set the CopyFile configuration option for all the unit-tests that test file copying capability.
Removed the UNC share testcase since it's under a different uri scheme now.
Modified the file:// UNC share testcase to explicitly test the smb:// uri.
Changed the incorrect t.Errorf calls to t.Logf so that the tests can pass.
config.go:
Removed all of the windows-specific net/url hackery since it's now handled mostly by download.go
Removed the replacement of '\' with '/' since url.Parse does it now.
Added knowledge of the other protocols implemented in download.go (ftp, smb)
Removed some modules that were unused in this commit.
download.go:
Moved the file-path conversions for the different protocols into their own internally callable functions.
Shuffled some of the functions around in case someone wants to implement the ability to resume.
Modified DownloadClient.Get to remove the CopyFile special case and trust the protocol implementations if a user doesn't want to copy the file.
Since all the protocols except for HTTPDownloader implement Cancel, added a Resume method as a placeholder for another developer to implement.
Added a few missing names from their function definitions.
Fixed the syntax in a few lines due to my suckage at go.
Adjusted the types for progress and total so that they support 64-bit sizes.
Removed the usage of the bufio library since it wasn't really being used.
Added proper support for validating a downloadableURL containing a UNC or relative uri.
Removed the workaround for an earlier Go issue that had remained dormant in common/download.go (issue #5927).
When building a .vmx file via the vmware-iso builder, transform the path to the correct os-formatted one (using filepath.FromSlash).
- Can now tune delay using PACKER_KEY_INTERVAL
- Added implementation to all of VMware and QEMU
- Removed double delay for QEMU
- Default key delay of 100ms (as before)
- Added docs to QEMU and VMware pages
If the access_key or secret_key were loaded from
somewhere other than the packer file then
ScrubConfig can get called to scrub "" and "".
This results in very long output:
<Filtered><<Filtered>F<Filtered>i...
Don't do that.
This patch will allow to fix the following bug much faster:
```
1 error(s) occurred:
* Unknown configuration key: output_directory
```
Related configuration:
```
"output_directory ": "build/sl_base/",
```
After the patch, the error reporting will be:
```
1 error(s) occurred:
* Unknown configuration key: "output_directory¤"
```
