Etcher currently elevates a child writer proxy that itself spawns the
Etcher CLI in robot mode, parses the output, and proxies those messages
to the GUI application over IPC.
After these set of changes, Etcher elevates a single child writer
process that directly communicates back with the GUI using IPC. The main
purpose behind these changes is to simplify the overall architecture and
fix various issues caused by the current complex child process tree.
Here's a summary of the changes:
- Stop wrapping the Etcher CLI to perform writing
- Remove the robot option from the Etcher CLI (along with related
documentation)
- Elevate a new `child-write.js` standalone executable
- Move the relevant bits of `lib/child-writer` to the `image-writer` GUI
module
- Remove the `lib/child-writer` directory
- Add a new "Child died unexpectedly" Mixpanel event
- Floor state percentage in the flash state model
The above changes made is possible to tackle all the remaining issues
where the writer process would remain alive even if the parent died.
Change-Type: patch
Changelog-Entry: Ensure the writer process dies when the GUI application is killed.

We fix the DEBUG environment variable by setting it on the `electron.remote`
instead, and we also move the code to `lib/gui/app.js` and away from
`lib/gui/index.html`.
Changelog-Entry: Set the DEBUG environment variable on the remote
electron process.
Change-Type: patch
* use debug.enabled, fix drivelist env setting
* fix: set debug env variable on remote electron process
We prompt the user with a sudo-prompt upon launch on Linux-based systems
to ensure the program has enough permissions for features needed
throughout the program's runtime.

This commit installs `node-usb` v1.3.0 from GitHub, since that version
was never published to NPM, and is the only one that works with Visual
Studio 2015 (see https://github.com/tessel/node-usb/issues/109).
The usbboot communicates with a Raspberry Pi / Amber through USB and
eventually mounts it as a block device we can write to.
This feature bundles bootcode.bin and start.elf from the original
usbboot implementation.
The flow is the following:
- On each scan, the usbboot scanner will try to get a usbboot compatible
USB device to the next "phase", until they are all transformed to
block devices the user can flash to as usual
Change-Type: minor
Changelog-Entry: Integrate Raspberry Pi's usbboot technology.
Fixes: https://github.com/resin-io/etcher/issues/1541

This disables full wildcard debug output by default now,
leave the possibility to manually enable selective debug output
via the `DEBUG` environment variable.
Change-Type: patch
- Extend the `standard` ESLint configuration
- Remove ESLint rules that are defined in the `standard` configuration
- Get rid of semi-colons

This commit changes the whole codebase to adhere to all StandardJS
guidelines rules except semicolons, since the removal of semicolons
affect pretty much all lines, and the final diff is very hard to follow
(and to assess other more involved changes).
In a nutshell:
- When using `function`, we now require a space before the opening
parenthesis
- If a line with operators is broken into multiple lines, the operator
should now go after the line break
- Unnecessary padding lines are now forbidden
There were also some minor things that the `standard` CLI caught that I
updated here.

Windows will not react to dynamically set environment variables (e.g:
`process.env.MOUNTUTILS_DEBUG = '1'`), so in order to workaround this
limitation, we set `MOUNTUTILS_DEBUG` in
`lib/child-writer/writer-proxy.js` when spawning the CLI, and we also
set `DEBUG='*'` in `lib/start.js`, so it gets picked up by the child
writer module, which spawns the writer proxy by inheriting the
environment.
After this change, the CLI becomes the only entity actually performing
I/O with the devices, and the GUI is just a wrapper around it.
When you click "Flash", the GUI spawns the CLI with all the appropriate
options, including `--ipc`, which uses an IPC communication channel to
report status back to the parent process.

This file runs the Etcher CLI if the binary was ran with
`ELECTRON_RUN_AS_NODE`, or the GUI otherwise.
