Summary: This fixes a two problems: * A mistake in `KeyedMutex.runExclusive`. * Logic about saving a document to s3 when the document is found to match what is already there. `HostedStorageManager.flushDoc` could get caught in a loop if a document was uploaded to s3 and then, without any change to it, marked as dirty. Low level code would detect there was no change and skip the upload; but then the snapshotId could be unknown, causing an error and retries. This diff fixes that problem by discovering the snapshotId on downloads and tracking it. It also corrects a mutex problem that may have been creating the scenario. A small delay is added to `flushDoc` to mitigate the effect of similar problems in future. Exponential backoff would be good, but `flushDoc` is called in some situations where long delays would negatively impact worker shutdown or user work.

Grist
Grist is a modern relational spreadsheet. It combine the flexibility of a spreadsheet with the robustness of a database to organize your data and make you more productive.
⚠️ This repository is in a pre-release state. Its release will be announced when it has all the planned components, and a solid independent build and test set-up. Currently, stand-alone server functionality is present, along with a single-user web client.
This repository, grist-core, is maintained by Grist Labs. Our flagship product, available at getgrist.com, is built from the code you see here, combined with business-specific software designed to scale it to many users, handle billing, etc.
If you are looking to use Grist in the cloud, head on over to getgrist.com.
Opening and editing a Grist document locally
The easiest way to use Grist locally on your computer is with Docker. From a terminal, do:
docker pull gristlabs/grist
docker run -p 8484:8484 -it gristlabs/grist
Then visit http://localhost:8484 in your browser. You'll be able to create and edit documents,
and to import documents downloaded from the https://docs.getgrist.com host. You'll also be able
to use the Grist API.
To preserve your work across docker runs, provide a directory to save it in:
docker pull gristlabs/grist
docker run -p 8484:8484 -v $PWD/persist:/persist -it gristlabs/grist
Building from source
Here are the steps needed:
npm install
npm run build:prod
npm run install:python
npm start
# unauthenticated grist client available at http://localhost:8484
# unauthenticated grist api available at http://localhost:8484/api/
Then you can use the Grist client, or the API. You cannot (yet) edit Grist documents
in place on your file system. All imported/created documents will appear in the docs
subdirectory.
Why Open Source?
By opening its source code and offering an OSI-approved free license, Grist benefits its users:
- Open Source Community. An active community is the main draw of open-source projects. Anyone can examine source code, and contribute bug fixes or even new features. This is a big deal for a general-purpose spreadsheet-like product, where there is a long tail of features vital to someone somewhere.
- Increased Trust. Because anyone can examine the source code, “security by obscurity” is not an option. Vulnerabilities in the code can be found by others and reported before they can cause damage.
- Independence. The published source code—and the product built from it—are available to you regardless of the fortunes of the Grist Labs business. Whatever happens to us, this repo or its forks can live on, so that you can continue to work on your data in Grist.
- Price Flexibility. You can build Grist from source and use it for yourself all you want without paying us a cent. While you can’t go wrong with our fully set-up and supported online service, some organizations may choose the do-it-yourself route and pay for their own server and maintenance, rather than a per-user price. DIY users are often the ones to develop new features, and can contribute them back to benefit all users of Grist.
- Extensibility. For developers, having the source open makes it easier to build extensions (such as the experimental Custom Widget). You can more easily include Grist in your pipeline. And if a feature is missing, you can just take the source code and build on top of it!
