* feat: rework record sync for improved reliability
So, to tell a story
1. We introduced the record sync, intended to be the new algorithm to
sync history.
2. On top of this, I added the KV store. This was intended as a simple
test of the record sync, and to see if people wanted that sort of
functionality
3. History remained syncing via the old means, as while it had issues it
worked more-or-less OK. And we are aware of its flaws
4. If KV syncing worked ok, history would be moved across
KV syncing ran ok for 6mo or so, so I started to move across history.
For several weeks, I ran a local fork of Atuin + the server that synced
via records instead.
The record store maintained ordering via a linked list, which was a
mistake. It performed well in testing, but was really difficult to debug
and reason about. So when a few small sync issues occured, they took an
extremely long time to debug.
This PR is huge, which I regret. It involves replacing the "parent"
relationship that records once had (pointing to the previous record)
with a simple index (generally referred to as idx). This also means we
had to change the recordindex, which referenced "tails". Tails were the
last item in the chain.
Now that we use an "array" vs linked list, that logic was also replaced.
And is much simpler :D
Same for the queries that act on this data.
----
This isn't final - we still need to add
1. Proper server/client error handling, which has been lacking for a
while
2. The actual history implementation on top
This exists in a branch, just without deletions. Won't be much to
add that, I just don't want to make this any larger than it already
is
The _only_ caveat here is that we basically lose data synced via the old
record store. This is the KV data from before.
It hasn't been deleted or anything, just no longer hooked up. So it's
totally possible to write a migration script. I just need to do that.
* update .gitignore
* use correct endpoint
* fix for stores with length of 1
* use create/delete enum for history store
* lint, remove unneeded host_id
* remove prints
* add command to import old history
* add enable/disable switch for record sync
* add record sync to auto sync
* satisfy the almighty clippy
* remove file that I did not mean to commit
* feedback
Without TLS config, the server fails to load defaults. Until this is
released, add this to your server config
```
[tls]
enable = false
cert_path = ""
pkey_path = ""
```
* Add TLS to atuin-server
atuin as a project already includes most of the dependencies necessary
for server-side TLS. This allows `atuin server start` to use a TLS
certificate when self-hosting in order to avoid the complication of
wrapping it in a TLS-aware proxy server.
Configuration is handled similar to the metrics server with its own
struct and currently accepts only the private key and certificate file
paths.
Starting a TLS server and a TCP server are divergent because the tests
need to bind to an arbitrary port to avoid collisions across tests. The
API to accomplish this for a TLS server is much more verbose.
* Fix clippy, fmt
* Add TLS section to self-hosting
* feat: add semver checking to client requests
This enforces that the client and the server run the same major version
in order to sync successfully.
We're using the `Atuin-Version` http header to transfer this information
If the user is not on the same MAJOR, then they will see an error like
this
> Atuin version mismatch! In order to successfully sync, the client and the server must run the same *major* version
> Client: 17.1.0
> Server: 18.1.0
> Error: could not sync records due to version mismatch
This change means two things
1. We will now only increment major versions if there is a breaking
change for sync
2. We can now add breaking changes to sync, for any version >17.1.0.
Clients will fail in a meaningful way.
* lint, fmt, etc
* only check for client newer than server
* Add version header to client too
* Add commands to print the default configuration
When updating a software I often want to compare my configuration with the
configuration of the new version. To make this possible atuin can now print
the default configuration.
This also updates the example files with the actual values used as default in
the settings.rs files.
* Changed command name to 'default-config'
* Fixed merge
* some simple server tests
* fmt
* logging in server test
* log server errors
* fix postgres uri
* postgres ports
* localhost again?
* Rebase fixes

* Add atuin account subcommands, and re-org delete
* Clarify docs
* Delete silly dupe migration
* Um where did this come from
* Oops, insert only plz
* At least patch this on the server side so we don't loop forever
* Postgres doesn't support <microsecond precision
Use millis - almost everything should support them and they are still
faster than a human can reasonably spam a button.
* Try different workspace structure
Move main crate (atuin) to be on the same level with other crates in
this workspace
* extract common dependencies to the workspace definition
* fix base64 v0.21 deprecation warning
* questionable: update deps & fix chrono deprecations
possible panic sites are unchanged, they're just more visible now
* Revert "questionable: update deps & fix chrono deprecations"
This reverts commit 993e60f8de.
* Drop events. I'd still like to do them, but differently
* Start adding delete api stuff
