* fix: map ForeignKeyViolation to AUTH in addRecipient
When a file is concurrently deleted while addRecipient runs, the FK
constraint on recipients.sender_id raises ForeignKeyViolation. Previously
this propagated as INTERNAL; now it returns AUTH (file not found).
* fix: only decrement usedStorage for uploaded files on expiration
expireServerFiles unconditionally subtracted file_size from usedStorage
for every expired file, including files that were never uploaded (no
file_path). Since reserve only increments usedStorage during upload,
expiring never-uploaded files caused usedStorage to drift negative.
* fix: handle setFilePath error in receiveServerFile
setFilePath result was discarded with void. If it failed (file deleted
concurrently, or double-upload where file_path IS NULL guard rejected
the second write), the server still reported FROk, incremented stats,
and left usedStorage permanently inflated. Now the error is checked:
on failure, reserved storage is released and AUTH is returned.
* fix: escape double quotes in COPY CSV status field
The status field (e.g. "blocked,reason=spam,notice={...}") is quoted in
CSV for COPY protocol, but embedded double quotes from BlockingInfo
notice (JSON) were not escaped. This could break CSV parsing during
import. Now double quotes are escaped as "" per CSV spec.
* fix: reject upload to blocked file in Postgres setFilePath
In Postgres mode, getFile returns a snapshot TVar for fileStatus. If a
file is blocked between getFile and setFilePath, the stale status check
passes but the upload should be rejected. Added status = 'active' to
the UPDATE WHERE clause so blocked files cannot receive uploads.
* fix: add CHECK constraint on file_size > 0
Prevents negative or zero file_size values at the database level.
Without this, corrupted data from import or direct DB access could
cause incorrect storage accounting (getUsedStorage sums file_size,
and expiredFiles casts to Word32 which wraps negative values).
* fix: check for existing data before database import
importFileStore now checks if the target database already contains
files and aborts with an error. Previously, importing into a non-empty
database would fail mid-COPY on duplicate primary keys, leaving the
database in a partially imported state.
* fix: clean up disk file when setFilePath fails in receiveServerFile
When setFilePath fails (file deleted or blocked concurrently, or
duplicate upload), the uploaded file was left orphaned on disk with
no DB record pointing to it. Now the file is removed on failure,
matching the cleanup in the receiveChunk error path.
* fix: check storeAction result in deleteOrBlockServerFile_
The store action result (deleteFile/blockFile) was discarded with void.
If the DB row was already deleted by a concurrent operation, the
function still decremented usedStorage, causing drift. Now the error
propagates via ExceptT, skipping the usedStorage adjustment.
* fix: check deleteFile result in expireServerFiles
deleteFile result was discarded with void. If a concurrent delete
already removed the file, deleteFile returned AUTH but usedStorage
was still decremented — causing double-decrement drift. Now the
usedStorage adjustment and filesExpired stat only run on success.
* refactor: merge STM store into Store.hs, parameterize server tests
- Move STMFileStore and its FileStoreClass instance from Store/STM.hs
back into Store.hs — the separate file was unnecessary indirection
for the always-present default implementation.
- Parameterize xftpFileTests over store backend using HSpec SpecWith
pattern (following SMP's serverTests approach). The same 11 tests
now run against both memory and PostgreSQL backends via a bracket
parameter, eliminating all *Pg test duplicates.
- Extract shared run* functions (runTestFileChunkDeliveryAddRecipients,
runTestWrongChunkSize, runTestFileChunkExpiration, runTestFileStorageQuota)
from inlined test bodies.
* refactor: clean up per good-code review
- Remove internal helpers from Postgres.hs export list (withDB, withDB',
handleDuplicate, assertUpdated, withLog are not imported externally)
- Replace local isNothing_ with Data.Maybe.isNothing in Env.hs
- Consolidate duplicate/unused imports in XFTPStoreTests.hs
- Add file_path IS NULL and status guards to STM setFilePath, matching
the Postgres implementation semantics
* test: parameterize XFTP server, agent and CLI tests over store backend
- xftpTest/xftpTest2/xftpTest4/xftpTestN now take XFTPTestBracket as
first argument, enabling the same test to run against both memory
and PostgreSQL backends.
- xftpFileTests (server tests), xftpAgentFileTests (agent tests), and
xftpCLIFileTests (CLI tests) are SpecWith-parameterized suites that
receive the bracket from HSpec's before combinator.
- Test.hs runs each parameterized suite twice: once with
xftpMemoryBracket, once with xftpPostgresBracket (CPP-guarded).
- STM-specific tests (store log restore/replay) stay in memory-only
xftpAgentTests. SNI/CORS tests stay in memory-only xftpServerTests.
* refactor: remove dead test wrappers after parameterization
Remove old non-parameterized test wrapper functions that were
superseded by the store-backend-parameterized test suites.
All test bodies (run* and _ functions) are preserved and called
from the parameterized specs. Clean up unused imports.
* feat: add manual tests and guide
* refactor: merge file_size CHECK into initial migration
* refactor: extract rowToFileRec shared by getFile sender/recipient paths
* refactor: parameterize XFTPServerConfig over store type
Embed XFTPStoreConfig s as serverStoreCfg field, matching SMP's
ServerConfig. runXFTPServer and newXFTPServerEnv now take a single
XFTPServerConfig s. Restore verifyCmd local helper structure.
* refactor: minimize diff in tests
Restore xftpServerTests and xftpAgentTests bodies to match master
byte-for-byte (only type signatures change for XFTPTestBracket
parameterization); inline the runTestXXX helpers that were split
on this branch.
* refactor: restore getFile position to match master
* refactor: rename withSTMFile back to withFile
* refactor: close store log inside closeFileStore for STM backend
Move STM store log close responsibility into closeFileStore to
match PostgresFileStore, removing the asymmetry where only PG's
close was self-contained.
STMFileStore holds the log in a TVar populated by newXFTPServerEnv
after readWriteFileStore; stopServer no longer needs the explicit
withFileLog closeStoreLog call. Writes still go through XFTPEnv.storeLog
via withFileLog (unchanged).
* refactor: rename XFTPTestBracket to XFTPTestServer
* fix: move file_size check from PG schema to store log import
* refactor: use SQL-standard type names in XFTP schema
* perf: batch expired file deletions with deleteFiles
* refactor: stream export instead of loading recipients into memory
* refactor: parameterize XFTP store with FSType singleton dispatch
* refactor: minimize diff per review feedback
* refactor: use types over strings, deduplicate parser
* refactor: always parse database store type, fail at startup
* fix compilation without postgresql
* refactor: always parse database store type, fail at startup
* lib: fix incorrect StrEncoding of Signature (it was not compatible with decoding, but was never used)
* align encoding with used in links (breaks backward compatibility)
* services: fix minor issues
* fix accounting for subscribed service queues, add prometheus stats
* fix uncorrelated subquery
* fix potential race condition when inserting service defensively, as it is also prevented by how client is created

* xftp-server: embed file download widget in XFTP server web page
When a URL has a hash fragment (>50 chars), the server page shows the
file download UI instead of the server info page. Embeds xftp-web
assets (JS, CSS, crypto worker) and protocol overlay with matching
website content. Overlay renders below the server navbar.
* xftp-server: fix overlay scroll lock, remove extra margin, fix dark SVG
* xftp-server: move file transfer widget to standalone /file page
* web: collapse all repeated Nothing sections in render
section_ only collapsed the first occurrence of a section when content
was Nothing, leaving subsequent sections with the same label intact.
This caused SMP server pages to show raw <x-xftpConfig> tags.
* xftp-server: update bundled css/js
* xftp-server: move file.html to xftp-server, rename xftp bundle dir
* web: remove unused server-info wrapper div
* refactor
* fix
