_It can be further reduced with another ~10MB once we replace entirely the `aws-sdk-go-v2` dependency but I stumbled on some edge cases related to the headers signing and for now is on hold._
- Added more elaborate warning message when restoring a backup explaining how the operation works.
- Skip irregular files (symbolic links, sockets, etc.) when restoring a backup zip from the Admin UI or calling `archive.Extract(src, dst)` because they come with too many edge cases and ambiguities.
This was initially reported as security issue (_thanks Harvey Spec_) but in the PocketBase context it is not something that can be exploited without an admin intervention and since the general expectations are that the PocketBase admins can do anything and they are the one who manage their server, this should be treated with the same diligence when using `scp`/`rsync`/`rclone`/etc. with untrusted file sources.
It is not possible (_or at least I'm not aware how to do that easily_) to perform virus/malicious content scanning on the uploaded backup archive files and some caution is always required when using the Admin UI or running shell commands, hence the backup-restore warning text.
**Or in other words, if someone sends you a file and tell you to upload it to your server (either as backup zip or manually via scp) obviously you shouldn't do that unless you really trust them.**
PocketBase is like any other regular application that you run on your server and there is no builtin "sandbox" for what the PocketBase process can execute. This is left to the developers to restrict on application or OS level depending on their needs. If you are self-hosting PocketBase you usually don't have to do that, but if you are offering PocketBase as a service and allow strangers to run their own PocketBase instances on your server then you'll need to implement the isolation mechanisms on your own.
- Removed conflicting styles causing the detailed codeblock log data preview to not visualize properly ([#4505](https://github.com/pocketbase/pocketbase/pull/4505)).
- Implemented the `FormData` interface and added support for sending `multipart/form-data` requests with `$http.send()` ([#4544](https://github.com/pocketbase/pocketbase/discussions/4544)).
- Added the field name as part of the `@request.data.someRelField.*` join to handle the case when a collection has 2 or more relation fields pointing to the same place ([#4500](https://github.com/pocketbase/pocketbase/issues/4500)).
- Updated Go deps and bumped the min Go version in the GitHub release action to Go 1.22.1 since it comes with [some security fixes](https://github.com/golang/go/issues?q=milestone%3AGo1.22.1).
- Fixed a small regression introduced with v0.22.0 that was causing some missing unknown fields to always return an error instead of applying the specific `nullifyMisingField` resolver option to the query.
- Fixed Admin UI record and collection panels not reinitializing properly on browser back/forward navigation ([#4462](https://github.com/pocketbase/pocketbase/issues/4462)).
- Initialize `RecordAuthWithOAuth2Event.IsNewRecord` for the `OnRecordBeforeAuthWithOAuth2Request` hook ([#4437](https://github.com/pocketbase/pocketbase/discussions/4437)).
_Note that in the future there will be also more advanced and granular options to specify a subset of the fields that are filterable/sortable._
- Added support for multiple back/indirect relation `expand` and updated the keys to use the `_via_` reference syntax (`yourCollection_via_yourRelField`).
_To minimize the breaking changes, the old parenthesis reference syntax (`yourCollection(yourRelField)`) will still continue to work but it is soft-deprecated and there will be a console log reminding you to change it to the new one._
- ⚠️ Collections and fields are no longer allowed to have `_via_` in their name to avoid collisions with the back/indirect relation reference syntax.
- Adjusted the `cron.Start()` to start the ticker at the `00` second of the cron interval ([#4394](https://github.com/pocketbase/pocketbase/discussions/4394)).
_Note that the cron format has only minute granularity and there is still no guarantee that the scheduled job will be always executed at the `00` second._
- Upgraded to `aws-sdk-go-v2` and added special handling for GCS to workaround the previous [GCS headers signature issue](https://github.com/pocketbase/pocketbase/issues/2231) that we had with v2.
_This should also fix the SVG/JSON zero response when using Cloudflare R2 ([#4287](https://github.com/pocketbase/pocketbase/issues/4287#issuecomment-1925168142), [#2068](https://github.com/pocketbase/pocketbase/discussions/2068), [#2952](https://github.com/pocketbase/pocketbase/discussions/2952))._
_⚠️ If you are using S3 for uploaded files or backups, please verify that you have a green check in the Admin UI for your S3 configuration (I've tested the new version with GCS, MinIO, Cloudflare R2 and Wasabi)._
- Other minor improvements (updated the `ghupdate` plugin to use the configured executable name when printing to the console, fixed the error reporting of `admin update/delete` commands, etc.).
- Fixed `@request.auth.*` initialization side-effect which caused the current authenticated user email to not being returned in the user auth response ([#2173](https://github.com/pocketbase/pocketbase/issues/2173#issuecomment-1932332038)).
_Previously on redirect error we were returning directly a standard json error response. Now on redirect error we'll redirect to a generic OAuth2 failure screen (similar to the success one) and will attempt to auto close the OAuth2 popup._
- Minor Admin UI improvements (reduced the min table row height, added option to duplicate fields, added new TinyMCE codesample plugin languages, hide the collection sync settings when the `Settings.Meta.HideControls` is enabled, etc.)
- Minor CSS fix for the Admin UI to prevent the searchbar within a popup from expanding too much and pushing the controls out of the visible area ([#4079](https://github.com/pocketbase/pocketbase/issues/4079#issuecomment-1876994116)).
- Small fix for a regression introduced with the recent `json` field changes that was causing View collection column expressions recognized as `json` to fail to resolve ([#4072](https://github.com/pocketbase/pocketbase/issues/4072)).
- Fixed the `json` field query comparisons to work correctly with plain JSON values like `null`, `bool``number`, etc. ([#4068](https://github.com/pocketbase/pocketbase/issues/4068)).
Since there are plans in the future to allow custom SQLite builds and also in some situations it may be useful to be able to distinguish `NULL` from `''`,
for the `json` fields (and for any other future non-standard field) we no longer apply `COALESCE` by default, aka.:
```
Dataset:
1) data: json(null)
2) data: json('')
For the filter "data = null" only 1) will resolve to TRUE.
For the filter "data = ''" only 2) will resolve to TRUE.
```
- Minor Go tests improvements
- Sorted the record cascade delete references to ensure that the delete operation will preserve the order of the fired events when running the tests.
- Marked some of the tests as safe for parallel execution to speed up a little the GitHub action build times.
- Added `--dev` flag and its accompanying `app.IsDev()` method (_in place of the previously removed `--debug`_) to assist during development ([#3918](https://github.com/pocketbase/pocketbase/discussions/3918)).
- Added new `PKCE()` and `SetPKCE(enable)` OAuth2 methods to indicate whether the PKCE flow is supported or not.
_The PKCE value is currently configurable from the UI only for the OIDC providers._
_This was added to accommodate OIDC providers that may throw an error if unsupported PKCE params are submitted with the auth request (eg. LinkedIn; see [#3799](https://github.com/pocketbase/pocketbase/discussions/3799#discussioncomment-7640312))._
- Added `expiry` field to the OAuth2 user response containing the _optional_ expiration time of the OAuth2 access token ([#3617](https://github.com/pocketbase/pocketbase/discussions/3617)).
- Allow a single OAuth2 user to be used for authentication in multiple auth collection.
_⚠️ Because now you can have more than one external provider with `collectionId-provider-providerId` pair, `Dao.FindExternalAuthByProvider(provider, providerId)` method was removed in favour of the more generic `Dao.FindFirstExternalAuthByExpr(expr)`._
- Use `IS NOT` instead of `!=` as not-equal SQL query operator to handle the cases when comparing with nullable columns or expressions (eg. `json_extract` over `json` field).
_Based on my local dataset I wasn't able to find a significant difference in the performance between the 2 operators, but if you stumble on a query that you think may be affected negatively by this, please report it and I'll test it further._
- Fixed graceful shutdown handling and speed up a little the app termination time.
- Limit the concurrent thumbs generation to avoid high CPU and memory usage in spiky scenarios ([#3794](https://github.com/pocketbase/pocketbase/pull/3794); thanks @t-muehlberger).
_Currently the max concurrent thumbs generation processes are limited to "total of logical process CPUs + 1"._
_This is arbitrary chosen and may change in the future depending on the users feedback and usage patterns._
_If you are experiencing OOM errors during large image thumb generations, especially in container environment, you can try defining the `GOMEMLIMIT=500MiB` env variable before starting the executable._
- Slightly speed up (~10%) the thumbs generation by changing from cubic (`CatmullRom`) to bilinear (`Linear`) resampling filter (_the quality difference is very little_).
- Added a default red colored Stderr output in case of a console command error.
_You can now also silence individually custom commands errors using the `cobra.Command.SilenceErrors` field._
- Fixed links formatting in the autogenerated html->text mail body.
- Relaxed the OAuth2 redirect url validation to allow any string value ([#3689](https://github.com/pocketbase/pocketbase/pull/3689); thanks @sergeypdev).
_Note that the redirect url format is still bound to the accepted values by the specific OAuth2 provider._
_This should fix the parsing of whitespace characters around view query column names when no quotes are used ([#3616](https://github.com/pocketbase/pocketbase/discussions/3616#discussioncomment-7398564))._
- Added support for `:excerpt(max, withEllipsis?)``fields` modifier that will return a short plain text version of any string value (html tags are stripped).
- Count the total records separately to speed up the query execution for large datasets ([#3344](https://github.com/pocketbase/pocketbase/issues/3344)).
- Enclosed the listing scrolling area within the table so that the horizontal scrollbar and table header are always reachable ([#2505](https://github.com/pocketbase/pocketbase/issues/2505)).
- Reintroduced the local `date` field tooltip on hover.
- Speed up the listing loading times for records with large `editor` field values by initially fetching only a partial of the records data (the complete record data is loaded on record preview/update).
- Removed the explicit `Content-Type` charset from the realtime response due to compatibility issues with IIS ([#3461](https://github.com/pocketbase/pocketbase/issues/3461)).
- Added global `raw` template function to allow outputting raw/verbatim HTML content in the JSVM templates ([#3476](https://github.com/pocketbase/pocketbase/discussions/3476)).
- Trimmed view query semicolon and allowed single quotes for column aliases ([#3450](https://github.com/pocketbase/pocketbase/issues/3450#issuecomment-1748044641)).
_Single quotes are usually [not a valid identifier quote characters](https://www.sqlite.org/lang_keywords.html), but for resilience and compatibility reasons SQLite allows them in some contexts where only an identifier is expected._
- Bumped the GitHub action to use [min Go 1.21.2](https://github.com/golang/go/issues?q=milestone%3AGo1.21.2) (_the fixed issues are not critical as they are mostly related to the compiler/build tools_).
- Fixed empty thumbs directories not getting deleted on Windows after deleting a record img file ([#3382](https://github.com/pocketbase/pocketbase/issues/3382)).
- Minor fix for the View collections API Preview and Admin UI listings incorrectly showing the `created` and `updated` fields as `N/A` when the view query doesn't have them.
- Fixed JS error in the Admin UI when listing records with invalid `relation` field value ([#3372](https://github.com/pocketbase/pocketbase/issues/3372)).
_This could happen usually only during custom SQL import scripts or when directly modifying the record field value without data validations._
- Added escape character (`\`) support in the Admin UI to allow using `select` field values with comma ([#2197](https://github.com/pocketbase/pocketbase/discussions/2197)).
- Exposed a global JSVM `readerToString(reader)` helper function to allow reading Go `io.Reader` values ([#3273](https://github.com/pocketbase/pocketbase/discussions/3273)).
- Bumped the GitHub action to use [min Go 1.21.1](https://github.com/golang/go/issues?q=milestone%3AGo1.21.1+label%3ACherryPickApproved) for the prebuilt executable since it contains some minor `html/template` and `net/http` security fixes.
- Prevent breaking the record form in the Admin UI in case the browser's localStorage quota has been exceeded when uploading or storing large `editor` values ([#3265](https://github.com/pocketbase/pocketbase/issues/3265)).
- Simplified the `serve` command to accept domain name(s) as argument to reduce any additional manual hosts setup that sometimes previously was needed when deploying on production ([#3190](https://github.com/pocketbase/pocketbase/discussions/3190)).
- Registered a custom Deflate compressor to speedup (_nearly 2-3x_) the backups generation for the sake of a small zip size increase.
_Based on several local tests, `pb_data` of ~500MB (from which ~350MB+ are several hundred small files) results in a ~280MB zip generated for ~11s (previously it resulted in ~250MB zip but for ~35s)._
- Added the application name as part of the autogenerated backup name for easier identification ([#3066](https://github.com/pocketbase/pocketbase/issues/3066)).
- Added new `SmtpConfig.LocalName` option to specify a custom domain name (or IP address) for the initial EHLO/HELO exchange ([#3097](https://github.com/pocketbase/pocketbase/discussions/3097)).
_This is usually required for verification purposes only by some SMTP providers, such as on-premise [Gmail SMTP-relay](https://support.google.com/a/answer/2956491)._
- To minimize the footguns with `Dao.FindFirstRecordByFilter()` and `Dao.FindRecordsByFilter()`, the functions now supports an optional placeholder params argument that is safe to be populated with untrusted user input.
- ⚠️ Deprecated `RelationOptions.DisplayFields` in favor of the new `SchemaField.Presentable` option to avoid the duplication when a single collection is referenced more than once and/or by multiple other collections.
- ⚠️ Fill the `LastVerificationSentAt` and `LastResetSentAt` fields only after a successfull email send ([#3121](https://github.com/pocketbase/pocketbase/issues/3121)).
- ⚠️ Skip API `fields` json transformations for non 20x responses ([#3176](https://github.com/pocketbase/pocketbase/issues/3176)).
- The `ApiScenario.AfterTestFunc` now receive as 3rd argument `*http.Response` pointer instead of `*echo.Echo` as the latter is not really useful in this context.
```go
// old
AfterTestFunc: func(t *testing.T, app *tests.TestApp, e *echo.Echo)
// new
AfterTestFunc: func(t *testing.T, app *tests.TestApp, res *http.Response)
```
- The `ApiScenario.TestAppFactory` now accept the test instance as argument and no longer expect an error as return result ([#3025](https://github.com/pocketbase/pocketbase/discussions/3025#discussioncomment-6592272)).
_Returning a `nil` app instance from the factory results in test failure. You can enforce a custom test failure by calling `t.Fatal(err)` inside the factory._
- Reduced the default JSVM prewarmed pool size to 25 to reduce the initial memory consumptions (_you can manually adjust the pool size with `--hooksPool=50` if you need to, but the default should suffice for most cases_).
- Update `gocloud.dev` dependency to v0.34 and explicitly set the new `NoTempDir` fileblob option to prevent the cross-device link error introduced with v0.33.
- Fixed the autogenerated `down` migrations to properly revert the old collection rules in case a change was made in `up` ([#3192](https://github.com/pocketbase/pocketbase/pull/3192); thanks @impact-merlinmarek).
_Existing `down` migrations can't be fixed but that should be ok as usually the `down` migrations are rarely used against prod environments since they can cause data loss and, while not ideal, the previous old behavior of always setting the rules to `null/nil` is safer than not updating the rules at all._
- Disabled the initial Admin UI admins counter cache when there are no initial admins to allow detecting externally created accounts (eg. with the `admin` command) ([#3106](https://github.com/pocketbase/pocketbase/issues/3106)).
- Downgraded `google/go-cloud` dependency to v0.32.0 until v0.34.0 is released to prevent the `os.TempDir``cross-device link` errors as too many users complained about it.
- Fixed Docker `cross-device link` error when creating `pb_data` backups on a local mounted volume ([#3089](https://github.com/pocketbase/pocketbase/issues/3089)).
- Fixed the error messages for relation to views ([#3090](https://github.com/pocketbase/pocketbase/issues/3090)).
The existing `data` prop will still work, but it is recommended to use `body` instead (_to send JSON you can use `JSON.stringify(...)` as body value_).
- Added `core.RealtimeConnectEvent.IdleTimeout` field to allow specifying a different realtime idle timeout duration per client basis ([#3054](https://github.com/pocketbase/pocketbase/discussions/3054)).
- Use relative path when redirecting to the OAuth2 providers page in the Admin UI to support subpath deployments ([#3026](https://github.com/pocketbase/pocketbase/pull/3026); thanks @sonyarianto).
- Trigger the JSVM `cronAdd()` handler only on app `serve` to prevent unexpected (and eventually duplicated) cron handler calls when custom console commands are used ([#3024](https://github.com/pocketbase/pocketbase/discussions/3024#discussioncomment-6592703)).
They are available by default with the prebuilt executable if you create `*.pb.js` file(s) in the `pb_hooks` directory.
Lower your expectations because the integration comes with some limitations. For more details please check the [Extend with JavaScript](https://pocketbase.io/docs/js-overview/) guide.
Optionally, you can also enable the JS app hooks as part of a custom Go build for dynamic scripting but you need to register the `jsvm` plugin manually:
- Added `record.ExpandedOne(rel)` and `record.ExpandedAll(rel)` helpers to retrieve casted single or multiple expand relations from the already loaded "expand" Record data.
- Added `Dao.WithoutHooks()` helper to create a new `Dao` from the current one but without the create/update/delete hooks.
- Use a default fetch function that will return all relations in case the `fetchFunc` argument of `Dao.ExpandRecord(record, expands, fetchFunc)` and `Dao.ExpandRecords(records, expands, fetchFunc)` is `nil`.
- For convenience it is now possible to call `Dao.RecordQuery(collectionModelOrIdentifier)` with just the collection id or name.
In case an invalid collection id/name string is passed the query will be resolved with cancelled context error.
- Refactored `apis.ApiError` validation errors serialization to allow `map[string]error` and `map[string]any` when generating the public safe formatted `ApiError.Data`.
- Added support for wrapped API errors (_in case Go 1.20+ is used with multiple wrapped errors, the first `apis.ApiError` takes precedence_).
- Added new utility `github.com/pocketbase/pocketbase/tools/template` subpackage to assist with rendering HTML templates using the standard Go `html/template` and `text/template` syntax.
- Added `types.JsonMap.Get(k)` and `types.JsonMap.Set(k, v)` helpers for the cases where the type aliased direct map access is not allowed (eg. in [goja](https://pkg.go.dev/github.com/dop251/goja#hdr-Maps_with_methods)).
- Soft-deprecated `security.NewToken()` in favor of `security.NewJWT()`.
-`Hook.Add()` and `Hook.PreAdd` now returns a unique string identifier that could be used to remove the registered hook handler via `Hook.Remove(handlerId)`.
- Changed the after* hooks to be called right before writing the user response, allowing users to return response errors from the after hooks.
There is also no longer need for returning explicitly `hook.StopPropagtion` when writing custom response body in a hook because we will skip the finalizer response body write if a response was already "committed".
- ⚠️ Renamed `*Options{}` to `Config{}` for consistency and replaced the unnecessary pointers with their value equivalent to keep the applied configuration defaults isolated within their function calls:
- ⚠️ Renamed `models.RequestData` to `models.RequestInfo` and soft-deprecated `apis.RequestData(c)` in favor of `apis.RequestInfo(c)` to avoid the stuttering with the `Data` field.
- Added new query parameter `?skipTotal=1` to skip the `COUNT` query performed with the list/search actions ([#2965](https://github.com/pocketbase/pocketbase/discussions/2965)).
If `?skipTotal=1` is set, the response fields `totalItems` and `totalPages` will have `-1` value (this is to avoid having different JSON responses and to differentiate from the zero default).
With the latest JS SDK 0.16+ and Dart SDK v0.11+ versions `skipTotal=1` is set by default for the `getFirstListItem()` and `getFullList()` requests.
- The count and regular select statements also now executes concurrently, meaning that we no longer perform normalization over the `page` parameter and in case the user
request a page that doesn't exist (eg. `?page=99999999`) we'll return empty `items` array.
- Reverted the default `COUNT` column to `id` as there are some common situations where it can negatively impact the query performance.
Additionally, from this version we also set `PRAGMA temp_store = MEMORY` so that also helps with the temp B-TREE creation when `id` is used.
_There are still scenarios where `COUNT` queries with `rowid` executes faster, but the majority of the time when nested relations lookups are used it seems to have the opposite effect (at least based on the benchmarks dataset)._
The change was necessary because I wasn't able to find an efficient way to track view changes and the previous behavior could have too many unexpected side-effects (eg. view with computed ids).
- Allowed `0` as `RelationOptions.MinSelect` value to avoid the ambiguity between 0 and non-filled input value ([#2817](https://github.com/pocketbase/pocketbase/discussions/2817)).
- Fixed zero-default value not being used if the field is not explicitly set when manually creating records ([#2992](https://github.com/pocketbase/pocketbase/issues/2992)).
Additionally, `record.Get(field)` will now always return normalized value (the same as in the json serialization) for consistency and to avoid ambiguities with what is stored in the related DB table.
- Added multiple valued fields (`relation`, `select`, `file`) normalizations to ensure that the zero-default value of a newly created multiple field is applied for already existing data ([#2930](https://github.com/pocketbase/pocketbase/issues/2930)).
- Register the `eagerRequestInfoCache` middleware only for the internal `api` group routes to avoid conflicts with custom route handlers ([#2914](https://github.com/pocketbase/pocketbase/issues/2914)).
- Fixed unique validator detailed error message not being returned when camelCase field name is used ([#2868](https://github.com/pocketbase/pocketbase/issues/2868)).
- Updated the index parser to allow no space between the table name and the columns list ([#2864](https://github.com/pocketbase/pocketbase/discussions/2864#discussioncomment-6373736)).
_This eliminates the temp B-TREE step when executing the query and for large datasets (eg. 150k) it could have 10x improvement (from ~580ms to ~60ms)._
- Fixed the selfupdate command not working on Windows due to missing `.exe` in the extracted binary path ([#2589](https://github.com/pocketbase/pocketbase/discussions/2589)).
- Added `int64`, `int32`, `uint`, `uint64` and `uint32` support when scanning `types.DateTime` ([#2602](https://github.com/pocketbase/pocketbase/discussions/2602))
- Fixed backups archive not excluding the local `backups` directory on Windows ([#2548](https://github.com/pocketbase/pocketbase/discussions/2548#discussioncomment-5979712)).
- Changed file field to not use `dataTransfer.effectAllowed` when dropping files since it is not reliable and consistent across different OS and browsers ([#2541](https://github.com/pocketbase/pocketbase/issues/2541)).
- Auto register the initial generated snapshot migration to prevent incorrectly reapplying the snapshot on Docker restart ([#2551](https://github.com/pocketbase/pocketbase/discussions/2551)).
- Fixed backup restore not working in a container environment when `pb_data` is mounted as volume ([#2519](https://github.com/pocketbase/pocketbase/issues/2519)).
- Fixed Dart SDK realtime API preview example ([#2523](https://github.com/pocketbase/pocketbase/pull/2523); thanks @xFrann).
- Updated the logs "real" user IP to check for `Fly-Client-IP` header and changed the `X-Forward-For` header to use the first non-empty leftmost-ish IP as it the closest to the "real IP".
- Added new `tools/cron` helper subpackage for scheduling task using cron-like syntax (_this eventually may get exported in the future in a separate repo_).
