Add git rolling instructions directly to depot_tools.
Also switches the download url to the non-deprecated gs direct download URL, and remove an ancient README.google that talked about software that's no longer distributed.

# Windows binary tool bootstrap
|
||||
|
||||
This directory has the 'magic' for the `depot_tools` windows binary update
|
||||
mechanisms.
|
||||
|
||||
## Software bootstrapped
|
||||
* Python (https://www.python.org/)
|
||||
* Git for Windows (https://git-for-windows.github.io/)
|
||||
* Subversion (https://subversion.apache.org/)
|
||||
|
||||
## Mechanism
|
||||
|
||||
Any time a user runs `gclient` on windows, it will invoke the `depot_tools`
|
||||
autoupdate script [depot_tools.bat](../../update_depot_tools.bat). This, in
|
||||
turn, will run [win_tools.bat](./win_tools.bat), which does the bulk of the
|
||||
work.
|
||||
|
||||
`win_tools.bat` will successively look to see if the local version of the binary
|
||||
package is present, and if so, if it's the expected version. If either of those
|
||||
cases is not true, it will download and unpack the respective binary.
|
||||
|
||||
Downloading is done with [get_file.js](./get_file.js), which is a windows script
|
||||
host javascript utility to vaguely impersonate `wget`.
|
||||
|
||||
Through a comedy of history, each binary is stored and retrieved differently.
|
||||
|
||||
### Git
|
||||
|
||||
Git installs are mirrored versions of the offical Git-for-Windows Portable
|
||||
releases.
|
||||
* Original: `https://github.com/git-for-windows/git/releases`
|
||||
* Mirror: `gs://chrome-infra/PortableGit*.7z.exe`
|
||||
|
||||
#### Updating git version
|
||||
1. Download the new `PortableGit-X.Y.Z-{32,64}.7z.exe` from the
|
||||
git-for-windows release page.
|
||||
1. From either console.developers.google.com or the CLI, do:
|
||||
1. Upload those to the gs://chrome-infra Google Storage bucket.
|
||||
1. Set the `allUsers Reader` permission (click the "Public link" checkbox
|
||||
next to the binaries).
|
||||
1. Edit the `set GIT_VERSION=X.Y.Z` line in `win_tools.bat` to be the new
|
||||
version.
|
||||
1. At the time of writing, the first version is the default version, and
|
||||
the second is the 'bleeding edge' version. You can use the bleeding edge
|
||||
version to get early feedback/stage a rollout/etc.
|
||||
1. Commit the CL.
|
||||
|
||||
Note that in order for the update to take effect, `gclient` currently needs to
|
||||
run twice. The first time it will update the `depot_tools` repo, and the second
|
||||
time it will see the new git version and update to it. This is a bug that should
|
||||
be fixed, in case you're reading this and this paragraph infuriates you more
|
||||
than the rest of this README.
|
||||
|
||||
### Python
|
||||
|
||||
Python installs are sourced from https://src.chromium.org/viewvc/chrome/trunk/tools/ .
|
||||
|
||||
The process to create them is sort-of-documented in the README of the python
|
||||
zip file.
|
||||
|
||||
### Subversion
|
||||
|
||||
Subversion installs are sourced from https://src.chromium.org/viewvc/chrome/trunk/tools/ .
|
||||
|
||||
There will likely never be an update to SVN in `depot_tools` from the current
|
||||
version.
