Delaying the auto-update check timer to start after one full round of
the provided frequency reduces the chance of upgrading immediately
after starting.
In the rare case that the updater downloads the same binary (validated via checksum)
we want to make sure that the updater does not attempt to upgrade and restart the cloudflared
process. The binaries are equivalent and this would provide no value.
However, we are covering this case because there was an errant deployment of cloudflared
that reported itself as an older version and was then stuck in an infinite loop
attempting to upgrade to the latest version which didn't exist. By making sure that
the binary is different ensures that the upgrade will be attempted and cloudflared
will be restarted to run the new version.
This change only affects cloudflared tunnels running with default settings or
`--no-autoupdate=false` which allows cloudflared to auto-update itself in-place. Most
distributions that handle package management at the operating system level are
not affected by this change.
This PR fixes some long standing bugs in the windows update
paths. We previously did not surface the errors at all leading to
this function failing silently.
This PR:
1. Now returns the ExitError if the bat run for update fails.
2. Fixes the errors surfaced by that return:
a. The batch file doesnt play well with spaces. This is fixed by
using PROGRA~1/2 which are aliases windows uses.
b. The existing script also seemed to be irregular about where batch
files were put and looked for. This is also fixed in this script.
- Move packages the provide generic functionality (such as config) from `cmd` subtree to top level.
- Remove all dependencies on `cmd` subtree from top level packages.
- Consolidate all code dealing with token generation and transfer to a single cohesive package.
