Phase 19a: what Nextcloud Social 0.26.126 fixed, taken up by the app

[AndyScherzinger]

Summary

Phase 19a: what Nextcloud Social fixed for the app, from the four fixes merged before this phase (#2437–#2440) to the ones reported during it and merged since, up to AlohaSocial/social master cdd847797 (0.26.126), each checked on the dev instance running that commit.

• Profile save (social#2485, 0.26.124): Social checks what it can refuse before writing anything and never answers 500 over half a profile, so a failed save is now a plain failure: the profile is no longer read back after a 5xx to see what was made. One multipart PATCH carries the pictures, names and fields.
• Account pictures (social#2487, 0.26.125): Social repairs the headers older versions stored as the account's avatar, sends one avatar on every route, and marks placeholders with avatar_default and header_default. Decoding reads a header_default header, and Mastodon's headers/{style}/missing.png (Mastodon has no flag), as no header, for every account rather than only on the profile, which knew missing.png alone. The account keeps whether its avatar is a stand-in, and Edit profile offers no removal of one, nor of a placeholder header.
• Profile post search (social#2481, 0.26.122): api/v2/search honours account_id and offset, so a profile's own post search is offered on Nextcloud Social as everywhere else.
• Edit history (social#2486, 0.26.121): each version carries its media, and the history sheet now lists each version's attachments by description, so an edit of a description alone shows.
• Uploads (social#2484, 0.26.123): image_size_limit and video_size_limit are capped at what PHP accepts, which the composer's pre-flight already checks against, and a refusal names its reason, which the attachment card already shows. No code change; the server notes say so.
• A new account (social#2440): answers verify_credentials and its first post with 200; the old 500 was seen on 0.26.97 and fixed in 0.26.104, and the /oauth/userinfo fallback stays for older servers. A Nextcloud user without a Social account cannot authorize an app at all.
• A flaky test: SyncEngineTest's thirty-second wait now allows for however long a loaded runner took.
• Docs: docs/02-server-api.md (new accounts, pictures, media, search and edits) and docs/14-status.md written as it reads after this merges: Phase 18 in part (Phase 18: the account's stream, and uploads sent once per file #33) and Phase 19a (this PR) under Built, profile post search on Social off the not-built list, nothing in progress.
• Also reported during the phase and commented on #2487: right after a save that changes the avatar, the answer named the previous copy.

Test plan

• OwnProfileTest: a save answered 500 is a failure with no follow-up verify_credentials.
• DtoDecodingTest: a header_default header and Mastodon's missing.png decode as none, a chosen header and a Pleroma upload named missing.png are kept; avatar_default is decoded and false without the flag. EditProfileTest: a stand-in avatar is shown but not offered for removal, a chosen one is.
• EditVersionsTest: each version's attachment descriptions, a blank one as none. Screenshot thread-history re-recorded with two attachments.
• On the dev instance (AlohaSocial/social cdd847797, 0.26.126), with curl as the app sends it: one multipart save of name, note, field, avatar and header answers 200 with them; a search with and without account_id; a description-only edit and its history; avatar and header removal; every existing account's header repaired to the placeholder with header_default: true; a fresh Social account (occ social:account:create) answering verify_credentials and its first post with 200, then removed. Not run through the app on the emulator (about 2 GB of memory free).
• Gates: detekt ktlintCheck lint alohaArchitectureCheck, alohaUnitTests on every module (StatusHtmlParserTest's one-second performance test timed out once under a fully loaded run and passed in 13 ms on its own), alohaScreenshotTests, assembleGenericRelease and assembleGplayRelease.

Checklist

• One concern; split if it approaches a thousand changed lines
• Tests for every non-trivial branch; fixtures from the dev instance where the server is involved
• detekt ktlintCheck lint alohaArchitectureCheck green, no baseline grown
• Screenshots re-recorded only where the UI change is intended
• Accessibility: labels, 48 dp targets, headings and paneTitle on new screens, 200 % font preview
• Strings in strings.xml with translator comments
• No new exported component, permission or dependency without a line here explaining it
• docs/ updated where behaviour changed
• AI tools were used for this contribution (commits carry Assisted-by:)

Summary by CodeRabbit

• New Features
  • Edit history now displays descriptions for attached media, with a fallback label when a description is missing.
  • Profile editing distinguishes server-provided stand-in avatars from chosen pictures, so stand-ins aren’t offered for removal.
  • Profile post search is no longer restricted by server type.
• Bug Fixes
  • Failed profile saves now report the server error instead of being treated as successful after reloading.
  • Missing header placeholders are handled consistently across supported servers.

📝 Walkthrough

Walkthrough

The changes update profile-save error handling, account-image decoding and profile editing, profile search, and thread edit-history media. They also revise server compatibility documentation and adjust the sync polling interval test.

Changes

Profile and server compatibility

Layer / File(s)	Summary
Account image data and decoding core/model/src/main/kotlin/social/aloha/core/model/Account.kt, core/network/src/main/kotlin/social/aloha/core/network/dto/AccountDto.kt, core/network/src/test/kotlin/social/aloha/core/network/dto/DtoDecodingTest.kt	Account records whether its avatar is a server default. DTO decoding reads default-image flags and removes recognized placeholder headers. Tests cover the decoded values.
Profile image and search UI feature/profile/src/main/kotlin/social/aloha/feature/profile/EditProfileScreen.kt, feature/profile/src/main/kotlin/social/aloha/feature/profile/EditProfileViewModel.kt, feature/profile/src/main/kotlin/social/aloha/feature/profile/ProfilePresentation.kt, feature/profile/src/main/kotlin/social/aloha/feature/profile/ProfileScreen.kt, feature/profile/src/main/kotlin/social/aloha/feature/profile/ProfileUiState.kt, feature/profile/src/main/kotlin/social/aloha/feature/profile/ProfileViewModel.kt, feature/profile/src/test/kotlin/social/aloha/feature/profile/*	Profile forms track whether a kept picture is chosen, and remove controls use that value. Profile search no longer uses the server-specific postSearch state property.
Server compatibility documentation docs/02-server-api.md, docs/14-status.md	The documentation describes versioned server behavior, image handling, upload responses, search, and completed or open work.

Profile save responses

Layer / File(s)

Summary

Save response handling and validation core/data/src/main/kotlin/social/aloha/core/data/profile/OwnProfile.kt, core/data/src/test/kotlin/social/aloha/core/data/profile/OwnProfileTest.kt, core/testing/src/main/kotlin/social/aloha/core/testing/SignedInFixture.kt, core/data/src/main/kotlin/social/aloha/core/data/SignInCoordinator.kt, core/database/src/main/kotlin/social/aloha/core/database/AccountsDatabase.kt, core/network/src/main/kotlin/social/aloha/core/network/endpoints/AccountExtraEndpoints.kt

Profile saves now return failed credential-update responses without reloading the profile to reconcile requested changes. A test verifies that HTTP 500 returns a server error after one credentials-update request. Related comments specify server-version and request-format details.

Thread edit-history media

Layer / File(s)	Summary
Media descriptions in edit history feature/thread/src/main/kotlin/social/aloha/feature/thread/ThreadUiState.kt, feature/thread/src/main/kotlin/social/aloha/feature/thread/ThreadPresentation.kt, feature/thread/src/main/kotlin/social/aloha/feature/thread/ThreadScreen.kt, feature/thread/src/main/res/values/strings.xml, feature/thread/src/test/kotlin/social/aloha/feature/thread/*	Edit versions now carry nullable media descriptions. The thread screen displays numbered descriptions or localized fallback text. Tests cover description mapping and screenshot data.

Polling interval test

Layer / File(s)	Summary
Polling interval assertion core/sync/src/test/kotlin/social/aloha/core/sync/SyncEngineTest.kt	The test uses monotonic elapsed time to check the remaining wait against the 30-second polling interval.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Feature

Merge Risk: 🔵 Low · up to 78d69

This change updates profile save, picture and edit-history handling and the related documentation. Remaining concerns are minor documentation wording issues, so the change is safe to merge with owner awareness.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 78d69

No new externally reachable interface or privilege expansion was identified. Profile saving now rejects ambiguous success more conservatively. Remaining uncertainty concerns failed writes on older servers and partial completion across separate picture-removal and profile-update requests.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The reviewed profile-write path remains scoped to the selected signed-in account and its API base. The changed local persistence operation affects that account's presentation fields rather than credentials or account identity; no broader service or environment authority was demonstrated.

Trust Boundaries and Controls

• observed — Server-provided picture flags and placeholder URL patterns affect account-image presentation and whether a kept picture is treated as user-chosen. They do not select credentials or the target account in the reviewed save flow. Newly displayed attachment descriptions pass to Compose Text rather than a new network request or executable-content sink.

Resilience and Maintainability Implications

• inferred — Removing heuristic success recognition avoids claiming that all requested privacy and profile changes succeeded merely because name and note match. It does not prove that a failed or interrupted request left remote state unchanged. Existing partial completion and concurrent-save behavior therefore remain bounded consistency uncertainties, not established PR-introduced authorization failures.

1-33: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Use JUnit 4 or JUnit 5 consistently with the guideline.

The test uses JUnit 4 (org.junit.Test). The test does not need Robolectric or Android framework behavior. It uses Color, which is a plain value class. The guideline says to use JUnit 5 for plain Kotlin tests. This module may use JUnit 4 only because of its Compose and Robolectric setup. Confirm the module's test runner supports JUnit 5. If it does, migrate the test.

As per coding guidelines: "**/src/test/kotlin/: Use JUnit 5 for plain Kotlin tests; when Android framework behavior is needed, use JUnit 4 with Robolectric."

Review comments at @docs/02-server-api.md:
- Line 15: Update the Pictures row to identify `header_default` as an Account
field or JSON property, not an HTTP header; retain the separate reference to the
app reading a `header_default` header.
- Around line 14-16: Update the version evidence in the “New accounts” and
“Pictures” notes so their behavioral claims are supported by releases through
0.26.125, citing newer release documentation or narrowing each claim to what the
existing documented versions establish. Preserve the existing distinctions
between version-specific behavior and observed behavior.
- Line 12: Update MediaUploadWorker so server, transport, and rate-limit
failures mark the upload as failed instead of retrying automatically. Preserve
the existing “Upload again” button as the user-initiated retry path, and revise
the media API documentation to state that server failures remain available for
manual retry.

Review comments at @docs/14-status.md:
- Line 27: Update the entry identified by “19a” to say that the app treats a
profile-save HTTP 500 as a failed save, without claiming Social avoids partial
persistence; retain the row’s other documented changes.
