instead of symlinking to fix#7534. The longer term fix for this would be to change the go-getter so that it can leave the source file where it is & tell us where it is.
We will do this when the right time comes.
Usually the builder validation should error when the checksum is empty, but for the virtualbox-ovf builder this is not validated. Which is something I didn't see when refactoring for go-getter incorporation/refactor.
* 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
There were 5 different formats for the Packer useragent string. This
fixes that and unifies it into a helper package.
I did not touch oracle's user-agent, because it looked kinda special.
Run now takes a context as well as a statebag. We'll assign the context
to the blank identifier to prevent namespace collisions. We'll let the
step authors opt-in to using the context.
`find . -iname "step_*.go" -exec gsed -i'' 's/func \(.*\)Run(/func \1Run(_ context.Context, /' {} \;`
In case of two or more iso_urls checks for downloaded files prior to downloading them.
Speedups case when some iso already downloaded and another url prepended to iso_urls list.
This driver talks directly to ESX over ssh, using vim-cmd, esxcli and sh;
no vCenter or VIM api required.
Remote* config properties added to support a remote driver
RemoteDriver interface extends Driver:
* SSHAddress - esx flavor uses esxcli to find the VM's ip address
* Download - esx flavor downloads iso files to a vmfs datastore
Driver can optionally implement the following interfaces:
* VNCAddressFinder - esx flavor needs to check remote ports
* OutputDir - esx driver needs a local and remote OutputDir
* Inventory - esx driver needs to register/unregister VMs
* HostIPFinder - esx flavor needs an address on the same network as esx itself
