Ah, I see: the security risk is forging new log entries via inserting newlines (or CRLF). We should be sanitizing the project code anyway, at an earlier point than this.

Yes, we are sanitizing the project code, and can't hit this code path with unsanitized user data. False positive.

Ready for review, but not yet ready to merge: there's a subtle writing-system-related bug I'm trying to pin down (see comment below).

There was a problem hiding this comment.
This is causing a bug: when a writing system ID would be canonicalized to a different value (e.g., one test project had qaa-x-qaa-v which SIL.Core canonicalizes to qaa-x-v), and then LfMerge produced the error "Unable to set writing system 'qaa-x-v' because this id already exists." I'm still working on a solution.

Solution implemented in an LfMerge PR; I'll merge that first, then this won't be a problem any more.

The Claude-generated code in 02c41f5 makes ProjectService.CreateProject and ProjectService.CreateDraftProject inconsistent with each other, and also with the GraphQL CreateProject mutation. Claude only added the optional Is that what we want? Pro: no change to graphQL inputs (apart from the new enum value), so no need for the GraphQL mutation handlers to implement the "admin-only" rule on setting ProjectOrigin in a new project. Con: inconsistency, no way for this to be set via GraphQL. I'm inclined to modify the CreateProjectInput to include that enum as an optional parameter (i.e. a nullable enum), so that the GraphQL mutations are consistent with the ProjectService methods. But that does mean a wider area where we need to get the admin checks right. EDIT: No, wait, that doesn't make sense. Our rule is that only admins can set ProjectOrigin, and admins will never be creating draft projects, so anyone creating a draft project would never be allowed to set ProjectOrigin anyway, so it makes no sense for CreateDraftProject to take that parameter. The inconsistency beteen CreateProject and CreateDraftProject is just fine here. |

Did a self-review. Lots of places where a comment needs to be edited or corrected, and a couple minor code changes. But this is close to being ready to merge. I do want to merge an LfMerge bugfix first, though.
Shared by LexBoxApi (query param) and FwHeadless (creation handler); None is the default. Values: None, Standard, Enhanced. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Builds a new FieldWorks project from the SIL.LCModel template and pushes it into the empty hg repo LexBox already created: clone the empty remote → build fw.fwdata (first vernacular + first analysis WS) → add the remaining writing systems via the existing CreateWritingSystem surface (dedup + save-on-dispose, then release LCM file locks) → hg add/commit → push. Guards the fdoDataModelVersion, cleans up the local folder on failure, and stubs anthropologyCategories (// TODO: Implement). Adds a per-project creation reservation to SyncHostedService so a sync can't be queued for a project mid-creation (and two creations can't race). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
POST /api/project/create-from-template (projectId query param + JSON body of vernacular/analysis writing systems and anthropologyCategories). Validates the WS tags with IetfLanguageTag at the boundary, resolves the code via IProjectLookupService, and delegates to ProjectCreationService. Registers the service and maps the route. Threads AnthropologyCategories through to the stub. Internal endpoint (cluster-only, no auth) — LexBoxApi does the admin check and the project/repo creation before calling this. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Posts the vernacular/analysis writing systems and anthropologyCategories to the FwHeadless create-from-template endpoint for a given project id. Runs inline; returns null on success or the error body on failure (for the controller's saga rollback). Threads a CancellationToken like the sibling methods. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
POST /api/project/createFromTemplate (admin only): validates the code and that at least one wsVernacular is given (400), rejects a taken code (409), defaults wsAnalysis to ["en"], then creates the FLEx project (Postgres row + empty repo) and asks FwHeadless to populate the repo with the template .fwdata. On FwHeadless failure it compensates by deleting the repo + project row; on success it refreshes LastCommit and returns the new project id. wsVernacular/wsAnalysis are repeatable query params; anthropologyCategories (enhanced|standard|none) defaults to none. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Unit tests (no infrastructure): ProjectController.CreateFromTemplate rejects a missing vernacular WS and an invalid code with 400; SyncHostedService's creation reservation blocks a second concurrent creation and refuses to queue a sync while a project is being created, and is reusable after release. The end-to-end (template build + empty-repo first push) is integration-level and runs in CI. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
- Close a TOCTOU race between TryStartProjectCreation and QueueJob (they checked each other's dictionary without a shared lock, so a sync could be queued for a project mid-creation and race on the repo). Both check-then-add paths now run under one lock. - AssertModelVersionMatches now fails closed: an unreadable version is treated as a mismatch rather than silently allowing the push. - Log a warning when a not-yet-implemented anthropologyCategories value is requested so the no-op stub isn't silent. - Route: null-safe writing-system checks and reject an empty analysis list with 400 (rather than a 500 from the service guard). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
- Propagate FwHeadless's status code: an invalid writing-system tag now surfaces as 400 instead of being flattened to 500 (FwHeadlessClient returns the status + body). - Give the FwHeadless HTTP client a 5-minute timeout so inline creation (cold LCM load + push) doesn't hit the 100s default. - Route the failure compensation through a new ProjectService.CleanupFailedProjectCreation so repo+row deletion and cache invalidation stay in one place (the controller no longer deletes the row directly and skip cache invalidation). - Extract the analysis-default (["en"]) into a testable helper. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
- Assert the ProblemDetails.Detail so each validation test proves its own branch (the two 400s were previously indistinguishable). - Add the mirror race case: a queued sync blocks a creation. - Cover the analysis-default helper (null/empty -> ["en"], supplied kept). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
End-to-end test (Category=Integration, CI-only — needs the lexbox stack): calls the admin createFromTemplate endpoint, then asserts the empty repo received the first commit (GetProjectLastCommit non-null; hgweb tip is no longer the all-zero hash) and that the pushed fw.fwdata carries the requested vernacular + analysis writing systems. Also asserts a missing vernacular is rejected with 400. Cleans up via softDeleteProject. This exercises the one path that can't be unit-tested: LfMergeBridge/Chorus pushing a locally-committed brand-new project into an empty remote repo. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
ProjectCreationService needs NewLangProj.fwdata (and its sibling template files) to build a new project, but FwDataBridgeConfig.TemplatesFolder defaults to the FieldWorks user-data dir (~/.local/share/fieldworks/Templates), which doesn't exist in the container — creation failed with DirectoryNotFoundException on NewLangProj.fwdata. Copy the SIL.LCModel package's contentFiles/Templates/* into FwHeadless's output and point TemplatesFolder at that shipped folder (AppContext.BaseDirectory/Templates) unless overridden in config. Mirrors how FwLiteWeb and the bridge tests ship the templates. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Creating a project from a template pushes into a repo LexBox has only `hg init`'d server-side, so it has zero changesets. Cloning that empty remote is a no-op that returns Success=true but leaves no local `.hg`, so the subsequent `hg add` failed with "no repository found ... (.hg not found)". Replace the clone with LfMerge's from-scratch genesis recipe (verified against the lfmerge reference implementation): `hg init` the local fw/ folder, set the branch to the FDO model version BEFORE the first commit, build the .fwdata, then commit + push. Chorus's Language_Forge_Send_Receive refuses to make the first-ever commit itself, so the manual CommitFile stays. The branch step is the data-correctness fix: FLEx clients clone looking for a branch named after the model version, so a first commit landing on `default` would be invisible to them. Numeric branch names work via the fixutf8 hg extension already wired into Mercurial/mercurial.ini. Adds InitRepo and SetBranch primitives to SendReceiveHelpers / ISendReceiveService. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
CreateNewLangProj takes a HashSet for additional writing systems, meaning it won't necessarily create them in the order we want. So immediately after creating the new project, we reorder its writing systems to match the order passed in the query params. We check whether liblcm has added any writing systems (for example, it will add `en` if it wasn't there), and we make sure those get kept.
Includes a unit test to ensure they're all ordered correctly
This will ensure that we don't end up adding a visible "en" to projects that didn't actually want one.
These two methods were always called one after another, and CommitEmpty has no other reason to exist. So we combine them. New method changes branch and creates an empty commit to switch to it immediately, but can optionally be told not to switch immediately.
This will let liblcm make the choice, instead of us enforcing an "en" default. Currently liblcm's default is already "en", but this would allow us to follow liblcm's lead if they change that default in the future.
This reverts commit d746810. Decided not to do this, for now, and stick with "en" as default UI WS.
We don't actually use a template in our code; that's a liblcm internal detail that we shouldn't be worrying about.
Add another OTel tag for consistency with other Mercurial helpers. Also make wording of various comments more consistent.
Currently projectOrigin is effectively admin-only because the entire API call is admin-only. But at some point we will remove `[AdminRequired]` and then we want the projectOrigin parameter to still be restricted to only site admins even when the rest of the API is opened up. Also have the projectOrigin test check that LanguageForgeNonSR is parsed case-insensitively, because we expect to actually use that one.

Keep the project row until repository deletion succeeds.
This method commits the database deletion before DeleteRepoIfExists. If repository deletion fails, the repository remains while the project code appears available in the database. The exception also skips cache invalidation.
A later creation can collide with or reuse the stale repository. Keep a retryable cleanup record, or delete the repository before committing the project-row deletion and preserve enough state to retry safely.

What about just moving line 253 to be in between lines 247 and 248? That would be the simplest fix. Any problems with that idea?

@rmunn, yes. Moving await hgService.DeleteRepoIfExists(code); to immediately after await fwHeadless.DeleteProject(projectId); fixes this finding.
If repository deletion fails, the project row remains. The project code remains unavailable. The caches also remain valid.
If SaveChangesAsync() fails after repository deletion, the project row remains and the cleanup can be retried. FwHeadlessClient.DeleteProject accepts 404 NotFound as success, and DeleteRepoIfExists is idempotent.
This is the smallest suitable fix.

No longer needed to work around Chorus plugin-finding bug now that LibChorus version 6.0.0-beta0074 is out.
This test addition should fail if Chorus ever starts failing to find its file-handler plugins again, because the symptom that would occur if that happened (the semantic domain list file would not be pushed) is exactly what this extra text check looks for.
An action's CancellationToken parameter binds to HttpContext.RequestAborted, which trips whenever the caller hangs up or its client times out. FwHeadless's initFwDataProject takes no cancellation token of its own, so it runs creation through to completion regardless. Aborting our wait therefore told us nothing about whether the project was created, while the catch block tore it down -- deleting the project row and the hg repo that FwHeadless was still pushing into. The 409 guard in CleanupFailedProjectCreation does not close the window, because the creation reservation is released as soon as creation returns. Drop the parameter rather than substituting another token: HttpClient.Timeout already bounds the call, and an unused token in scope invites someone to thread it back in. Compensate only when FwHeadless has answered with a failure; on no answer at all, log and leave the project in place, since an orphaned empty project is recoverable by an admin and a half-deleted one is not.

Creation is a long-running operation with no way to ask how it is going, so a caller has to hold a request open for the whole thing. Give it the same polling shape the merge routes already have: GET /api/project/creation-status (mirrors /api/merge/status) GET /api/project/await-creation-finished (mirrors /api/merge/await-finished) The creation reservation in SyncHostedService now carries a TaskCompletionSource<ProjectCreationStatus>, exactly as the sync reservation does, so ProjectCreationService can publish its outcome to anyone waiting. Results are cached for 5 minutes rather than the sync path's 30 seconds, because a caller whose own request timed out partway through needs to be able to come back later and learn how it ended. When nothing is in flight and no result is remembered, the status is derived from durable state (the .fwdata is on disk after a success, and the project folder is deleted after a failure), so it survives a FwHeadless restart. Giving up on the await reports TimedOutAwaitingCreation rather than an error: creation takes no cancellation token, so abandoning the wait says nothing about whether the project was created. Nothing consumes these yet; the POST remains blocking. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Wraps the two endpoints added in the previous commit: CreationStatus -> GET /api/project/creation-status AwaitCreationFinished -> GET /api/project/await-creation-finished Both take a cancellation token and callers may pass RequestAborted, which looks like it contradicts the earlier fix but does not: abandoning a status read starts no durable work and leaves nothing to act on, while abandoning the creation call leaves work running that we cannot observe. The rule is about what a call sets in motion, not about tokens; the reason is recorded on CreationStatus so it isn't rediscovered the hard way. AwaitCreationFinished translates its own timeout into TimedOutAwaitingCreation. FwHeadless only produces that status when its RequestAborted trips, which happens because we hung up, so its response arrives on a connection we already dropped. Reporting it ourselves gives callers one contract no matter which side stopped waiting. (The merge pair has the same gap; left alone as out of scope here.) Also sketches the return-202-and-poll alternative in ProjectController as commented-out code, so the trade-offs can be discussed against something concrete. It records what FwHeadless would need, and the open question that keeps it a comment: with nobody waiting, who compensates a failed creation, and where does the creation state live once it has to survive a restart? Nothing calls the new methods yet; the POST stays blocking. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

This is a new Lexbox API to create a new repo populated with a FLEx project, rather than requiring users to create an empty repo and then push into it from FW Classic. Due to our using the LfMergeBridge code (which refuses to create a new Mercurial branch), projects created with this code end up with three initial commits in Mercurial, rather than the two initial commits that projects created in FLEx end up with. But one of them is an empty commit that simply changes branches to
750000.7000072(and creates the branch in the process), and that doesn't cause any problems for Chorus or FLExBridge.Self-review done, have identified a few issues to work on. Mostly comment editing, but a couple unit tests I want to add (and one method I want to get rid of).
Fixes #2589.
