When processes try to write to the config concurrently, it is likely

that one process "wins" and the other process(es) fail to lock the

config file. By configuring a timeout larger than zero, Git can be

told to try to lock the config again a couple times within the

specified timeout. If the timeout is configure to zero (which is the
|
||||
default), Git will fail immediately when the config is already
|
||||
locked.

Access the `gvfs/info` endpoint of the specified remote (default:

In contrast to the `--get` command mode (which only accesses the local

repository), this command mode triggers a request via the network that

potentially requires authentication. If authentication is required, the

configured credential helper is employed (see linkgit:git-credential[1]

for details).

Frequently Asked Questions
|
||||
==========================
|
||||
|
||||
Using Scalar
|
||||
------------
|
||||
|
||||
### I don't want a sparse clone, I want every file after I clone!
|
||||
|
||||
Run `scalar clone --full-clone <url>` to initialize your repo to include
|
||||
every file. You can switch to a sparse-checkout later by running
|
||||
`git sparse-checkout init --cone`.
|
||||
|
||||
### I already cloned without `--full-clone`. How do I get everything?
|
||||
|
||||
Run `git sparse-checkout disable`.
|
||||
|
||||
Scalar Design Decisions
|
||||
-----------------------
|
||||
|
||||
There may be many design decisions within Scalar that are confusing at first
|
||||
glance. Some of them may cause friction when you use Scalar with your existing
|
||||
repos and existing habits.
|
||||
|
||||
> Scalar has the most benefit when users design repositories
|
||||
> with efficient patterns.
|
||||
|
||||
For example: Scalar uses the sparse-checkout feature to limit the size of the
|
||||
working directory within a large monorepo. It is designed to work efficiently
|
||||
with monorepos that are highly componentized, allowing most developers to
|
||||
need many fewer files in their daily work.
|
||||
|
||||
### Why does `scalar clone` create a `<repo>/src` folder?
|
||||
|
||||
Scalar uses a file system watcher to keep track of changes under this `src` folder.
|
||||
Any activity in this folder is assumed to be important to Git operations. By
|
||||
creating the `src` folder, we are making it easy for your build system to
|
||||
create output folders outside the `src` directory. We commonly see systems
|
||||
create folders for build outputs and package downloads. Scalar itself creates
|
||||
these folders during its builds.
|
||||
|
||||
Your build system may create build artifacts such as `.obj` or `.lib` files
|
||||
next to your source code. These are commonly "hidden" from Git using
|
||||
`.gitignore` files. Having such artifacts in your source tree creates
|
||||
additional work for Git because it needs to look at these files and match them
|
||||
against the `.gitignore` patterns.
|
||||
|
||||
By following the `src` pattern Scalar tries to establish and placing your build
|
||||
intermediates and outputs parallel with the `src` folder and not inside it,
|
||||
you can help optimize Git command performance for developers in the repository
|
||||
by limiting the number of files Git needs to consider for many common
|
||||
operations.

Getting Started
|
||||
===============
|
||||
|
||||
Registering existing Git repos
|
||||
------------------------------
|
||||
|
||||
To add a repository to the list of registered repos, run `scalar register [<path>]`.
|
||||
If `<path>` is not provided, then the "current repository" is discovered from
|
||||
the working directory by scanning the parent paths for a path containing a `.git`
|
||||
folder, possibly inside a `src` folder.
|
||||
|
||||
To see which repositories are currently tracked by the service, run
|
||||
`scalar list`.
|
||||
|
||||
Run `scalar unregister [<path>]` to remove the repo from this list.
|
||||
|
||||
Creating a new Scalar clone
|
||||
---------------------------------------------------
|
||||
|
||||
The `clone` verb creates a local enlistment of a remote repository using the
|
||||
partial clone feature available e.g. on GitHub, or using the
|
||||
[GVFS protocol](https://github.com/microsoft/VFSForGit/blob/HEAD/Protocol.md),
|
||||
such as Azure Repos.
|
||||
|
||||
```
|
||||
scalar clone [options] <url> [<dir>]
|
||||
```
|
||||
|
||||
Create a local copy of the repository at `<url>`. If specified, create the `<dir>`
|
||||
directory and place the repository there. Otherwise, the last section of the `<url>`
|
||||
will be used for `<dir>`.
|
||||
|
||||
At the end, the repo is located at `<dir>/src`. By default, the sparse-checkout
|
||||
feature is enabled and the only files present are those in the root of your
|
||||
Git repository. Use `git sparse-checkout set` to expand the set of directories
|
||||
you want to see, or `git sparse-checkout disable` to expand to all files. You
|
||||
can explore the subdirectories outside your sparse-checkout specification using
|
||||
`git ls-tree HEAD`.
|
||||
|
||||
### Sparse Repo Mode
|
||||
|
||||
By default, Scalar reduces your working directory to only the files at the
|
||||
root of the repository. You need to add the folders you care about to build up
|
||||
to your working set.
|
||||
|
||||
* `scalar clone <url>`
|
||||
* Please choose the **Clone with HTTPS** option in the `Clone Repository` dialog in Azure Repos, not **Clone with SSH**.
|
||||
* `cd <root>\src`
|
||||
* At this point, your `src` directory only contains files that appear in your root
|
||||
tree. No folders are populated.
|
||||
* Set the directory list for your sparse-checkout using:
|
||||
1. `git sparse-checkout set <dir1> <dir2> ...`
|
||||
2. `git sparse-checkout set --stdin < dir-list.txt`
|
||||
* Run git commands as you normally would.
|
||||
* To fully populate your working directory, run `git sparse-checkout disable`.
|
||||
|
||||
If instead you want to start with all files on-disk, you can clone with the
|
||||
`--full-clone` option. To enable sparse-checkout after the fact, run
|
||||
`git sparse-checkout init --cone`. This will initialize your sparse-checkout
|
||||
patterns to only match the files at root.
|
||||
|
||||
If you are unfamiliar with what directories are available in the repository,
|
||||
then you can run `git ls-tree -d --name-only HEAD` to discover the directories
|
||||
at root, or `git ls-tree -d --name-only HEAD <path>` to discover the directories
|
||||
in `<path>`.
|
||||
|
||||
### Options
|
||||
|
||||
These options allow a user to customize their initial enlistment.
|
||||
|
||||
* `--full-clone`: If specified, do not initialize the sparse-checkout feature.
|
||||
All files will be present in your `src` directory. This behaves very similar
|
||||
to a Git partial clone in that blobs are downloaded on demand. However, it
|
||||
will use the GVFS protocol to download all Git objects.
|
||||
|
||||
* `--cache-server-url=<url>`: If specified, set the intended cache server to
|
||||
the specified `<url>`. All object queries will use the GVFS protocol to this
|
||||
`<url>` instead of the origin remote. If the remote supplies a list of
|
||||
cache servers via the `<url>/gvfs/config` endpoint, then the `clone` command
|
||||
will select a nearby cache server from that list.
|
||||
|
||||
* `--branch=<ref>`: Specify the branch to checkout after clone.
|
||||
|
||||
* `--local-cache-path=<path>`: Use this option to override the path for the
|
||||
local Scalar cache. If not specified, then Scalar will select a default
|
||||
path to share objects with your other enlistments. On Windows, this path
|
||||
is a subdirectory of `<Volume>:\.scalarCache\`. On Mac, this path is a
|
||||
subdirectory of `~/.scalarCache/`. The default cache path is recommended so
|
||||
multiple enlistments of the same remote repository share objects on the
|
||||
same device.
|
||||
|
||||
### Advanced Options
|
||||
|
||||
The options below are not intended for use by a typical user. These are
|
||||
usually used by build machines to create a temporary enlistment that
|
||||
operates on a single commit.
|
||||
|
||||
* `--single-branch`: Use this option to only download metadata for the branch
|
||||
that will be checked out. This is helpful for build machines that target
|
||||
a remote with many branches. Any `git fetch` commands after the clone will
|
||||
still ask for all branches.
|
||||
|
||||
Removing a Scalar Clone
|
||||
-----------------------
|
||||
|
||||
Since the `scalar clone` command sets up a file-system watcher (when available),
|
||||
that watcher could prevent deleting the enlistment. Run `scalar delete <path>`
|
||||
from outside of your enlistment to unregister the enlistment from the filesystem
|
||||
watcher and delete the enlistment at `<path>`.

Scalar: Enabling Git at Scale
|
||||
=============================
|
||||
|
||||
Scalar is a tool that helps Git scale to some of the largest Git repositories.
|
||||
It achieves this by enabling some advanced Git features, such as:
|
||||
|
||||
* *Partial clone:* reduces time to get a working repository by not
|
||||
downloading all Git objects right away.
|
||||
|
||||
* *Background prefetch:* downloads Git object data from all remotes every
|
||||
hour, reducing the amount of time for foreground `git fetch` calls.
|
||||
|
||||
* *Sparse-checkout:* limits the size of your working directory.
|
||||
|
||||
* *File system monitor:* tracks the recently modified files and eliminates
|
||||
the need for Git to scan the entire worktree.
|
||||
|
||||
* *Commit-graph:* accelerates commit walks and reachability calculations,
|
||||
speeding up commands like `git log`.
|
||||
|
||||
* *Multi-pack-index:* enables fast object lookups across many pack-files.
|
||||
|
||||
* *Incremental repack:* Repacks the packed Git data into fewer pack-file
|
||||
without disrupting concurrent commands by using the multi-pack-index.
|
||||
|
||||
By running `scalar register` in any Git repo, Scalar will automatically enable
|
||||
these features for that repo (except partial clone) and start running suggested
|
||||
maintenance in the background using
|
||||
[the `git maintenance` feature](https://git-scm.com/docs/git-maintenance).
|
||||
|
||||
Repos cloned with the `scalar clone` command use partial clone or the
|
||||
[GVFS protocol](https://github.com/microsoft/VFSForGit/blob/HEAD/Protocol.md)
|
||||
to significantly reduce the amount of data required to get started
|
||||
using a repository. By delaying all blob downloads until they are required,
|
||||
Scalar allows you to work with very large repositories quickly. The GVFS
|
||||
protocol allows a network of _cache servers_ to serve objects with lower
|
||||
latency and higher throughput. The cache servers also reduce load on the
|
||||
central server.

|

The Philosophy of Scalar
|
||||
========================
|
||||
|
||||
The team building Scalar has **opinions** about Git performance. Scalar
|
||||
takes out the guesswork by automatically configuring your Git repositories
|
||||
to take advantage of the latest and greatest features. It is difficult to
|
||||
say that these are the absolute best settings for every repository, but
|
||||
these settings do work for some of the largest repositories in the world.
|
||||
|
||||
Scalar intends to do very little more than the standard Git client. We
|
||||
actively implement new features into Git instead of Scalar, then update
|
||||
Scalar only to configure those new settings. In particular, we ported
|
||||
features like background maintenance to Git to make Scalar simpler and
|
||||
make Git more powerful.
|
||||
|
||||
Scalar ships inside [a custom version of Git][microsoft-git], but we are
|
||||
working to make it available in other forks of Git. The only feature
|
||||
that is not intended to ever reach the standard Git client is Scalar's use
|
||||
of [the GVFS Protocol][gvfs-protocol], which is essentially an older
|
||||
version of [Git's partial clone feature](https://github.blog/2020-12-21-get-up-to-speed-with-partial-clone-and-shallow-clone/)
|
||||
that was available first in Azure Repos. Services such as GitHub support
|
||||
only partial clone instead of the GVFS protocol because that is the
|
||||
standard adopted by the Git project. If your hosting service supports
|
||||
partial clone, then we absolutely recommend it as a way to greatly speed
|
||||
up your clone and fetch times and to reduce how much disk space your Git
|
||||
repository requires. Scalar will help with this!
|
||||
|
||||
If you don't use the GVFS Protocol, then most of the value of Scalar can
|
||||
be found in the core Git client. However, most of the advanced features
|
||||
that really optimize Git's performance are off by default for compatibility
|
||||
reasons. To really take advantage of Git's latest and greatest features,
|
||||
you either need to study the [`git config` documentation](https://git-scm.com/docs/git-config)
|
||||
and regularly read [the Git release notes](https://github.com/git/git/tree/master/Documentation/RelNotes).
|
||||
Even if you do all that work and customize your Git settings on your machines,
|
||||
you likely will want to share those settings with other team members.
|
||||
Or, you can just use Scalar!
|
||||
|
||||
Using `scalar register` on an existing Git repository will give you these
|
||||
benefits:
|
||||
|
||||
* Additional compression of your `.git/index` file.
|
||||
* Hourly background `git fetch` operations, keeping you in-sync with your
|
||||
remotes.
|
||||
* Advanced data structures, such as the `commit-graph` and `multi-pack-index`
|
||||
are updated automatically in the background.
|
||||
* If using macOS or Windows, then Scalar configures Git's builtin File System
|
||||
Monitor, providing faster commands such as `git status` or `git add`.
|
||||
|
||||
Additionally, if you use `scalar clone` to create a new repository, then
|
||||
you will automatically get these benefits:
|
||||
|
||||
* Use Git's partial clone feature to only download the files you need for
|
||||
your current checkout.
|
||||
* Use Git's [sparse-checkout feature][sparse-checkout] to minimize the
|
||||
number of files required in your working directory.
|
||||
[Read more about sparse-checkout here.][sparse-checkout-blog]
|
||||
* Create the Git repository inside `<repo-name>/src` to make it easy to
|
||||
place build artifacts outside of the Git repository, such as in
|
||||
`<repo-name>/bin` or `<repo-name>/packages`.
|
||||
|
||||
We also admit that these **opinions** can always be improved! If you have
|
||||
an idea of how to improve our setup, consider
|
||||

Troubleshooting
|
||||
===============
|
||||
|
||||
Diagnosing Issues
|
||||
-----------------
|
||||
|
||||
The `scalar diagnose` command collects logs and config details for the current
|
||||
repository. The resulting zip file helps root-cause issues.
|
||||
|
||||
When run inside your repository, creates a zip file containing several important
|
||||
files for that repository. This includes:
|
||||
|
||||
* Configuration files from your `.git` folder, such as the `config` file,
|
||||
`index`, `hooks`, and `refs`.
|
||||
|
||||
* A summary of your Git object database, including the number of loose objects
|
||||
and the names and sizes of pack-files.
|
||||
|
||||
As the `diagnose` command completes, it provides the path of the resulting
|
||||
zip file. This zip can be attached to bug reports to make the analysis easier.
|
||||
|
||||
Modifying Configuration Values
|
||||
------------------------------
|
||||
|
||||
The Scalar-specific configuration is only available for repos using the
|
||||
GVFS protocol.
|
||||
|
||||
### Cache Server URL
|
||||
|
||||
When using an enlistment cloned with `scalar clone` and the GVFS protocol,
|
||||
you will have a value called the cache server URL. Cache servers are a feature
|
||||
of the GVFS protocol to provide low-latency access to the on-demand object
|
||||
requests. This modifies the `gvfs.cache-server` setting in your local Git config
|
||||
file.
|
||||
|
||||
Run `scalar cache-server --get` to see the current cache server.
|
||||
|
||||
Run `scalar cache-server --list` to see the available cache server URLs.
|
||||
|
||||
Run `scalar cache-server --set=<url>` to set your cache server to `<url>`.
