ipfs update command #169
Description
As discussed in #30 and #31, IPFS should be a self-updating tool. I think this should happen with:
- an internal update routine (probably using @inconshreveable's go-update
- a manual
ipfs updatecommand, described below. - optional auto-updating.
ipfs update
It should work like this:
# update to a specific (semver) version
> ipfs update <version>
> ipfs update 1.2.3
Your old version was: 1.2.2
Updated to (latest) version: 1.2.3 # (latest) only if actually latest
# update to latest minor/patch version
> ipfs update # (if newest version is backwards-compatible)
Your old version was: 1.2.2
Updated to latest version: 1.2.3
> ipfs update # (if newest version is backwards-incompatible)
Your old version was: 1.2.2
Updated to latest (backwards-compatible) version: 1.2.3
Note: There is a newer (backwards-incompatible) version: 2.0.0.
Run with the --latest flag to update to this version.
# update to latest version
> ipfs update latest
Your old version was: 1.2.2
Updated to latest version: 2.0.0
# list available updates, but don't update
> ipfs update check
Your current version: 1.2.2
New version available: 1.2.3
> ipfs update check
Your current version: 1.2.2
New backwards-compatible version available: 1.2.3
New backwards-incompatible version available: 2.0.0
> ipfs update log
# ipfs update log
## 1.2.3
This version includes a few simple bugfixes.
* abcdfre - fixed bug in cmd parsing
* 123abcd - fixed bug in http serve
## 1.2.2
...Flags (these are nice-to haves, here for doc purposes):
--dry-rundon't actually do it. go through the motions but don't actually install update. useful for testing. (maybe, not a priority)--keyprovide a different key for checking signature--ignore-signaturedon't check signature
The cmd help should be:
UsageLine: "update [<version>]",
Short: "Update the go-ipfs tool",
Long: `ipfs update [<version>] - Update the go-ipfs tool
ipfs update - Update to latest (backwards-compatible) version
ipfs update latest - Update to latest version
ipfs update <version> - Update to a specific version
ipfs update check - List new versions available
ipfs update log - Shows the update log
This command updates the ipfs tool itself. It downloads new versions from the
internet, checks digital signatures, and takes care of the installation.
