add env variable `OXICLOUD_WEBDAV_DRIVE_LISTING_PREFIX`
which is by default:
`OXICLOUD_WEBDAV_DRIVE_LISTING_PREFIX="@drive"`
so `/webdav/` -> points to user's personal drive (**backward compatibilit**y)
`/web/dav/@drive/{uuid|drive name}/` points to the respective drive
if admins want directly `/webdav/` pointing to list of drives they need to:
`OXICLOUD_WEBDAV_DRIVE_LISTING_PREFIX=""`
+ ensure lock is per user (RFC 4918 §9.11)
fix: #554
Every upload surface previously wrote each byte to disk twice: the HTTP
body was spooled to a temp file (or assembled from chunk parts), then
mmap-re-read for FastCDC analysis, and finally the new chunks were
written to the blob backend. CDC could not start until the last byte
arrived, so large uploads paid receive + reread + rewrite latency.
The dedup engine now chunks, hashes and settles the stream WHILE it
arrives (fastcdc AsyncStreamCDC + incremental BLAKE3):
- Each batch of distinct chunks is pinned-or-classified by ONE
`UPDATE … RETURNING` (no check-then-bump TOCTOU; pinned chunks can't
be reclaimed mid-upload), and only chunks the store doesn't have are
written — a full dedup hit performs zero content writes.
- Durability before visibility is preserved: one batched fsync sweep,
then one batched INSERT, then the manifest. Identical concurrent
uploads are resolved at the manifest INSERT via ON CONFLICT (the
loser releases its references and becomes a dedup hit).
- A drop guard rolls back pins and surfaces written-but-unregistered
chunks to GC if the request future is cancelled mid-stream.
- MIME sniffing now peeks the first bytes in-flight; client-requested
MD5/SHA-256 checksums are computed by a stream tee — the post-upload
re-read of the assembled file is gone.
All surfaces converge on the new interfaces::upload_ingest helper:
REST multipart, WebDAV PUT, NextCloud PUT, WOPI PutFile, the dedup
endpoint, and both chunked-upload completions (which now stream their
ordered parts straight into the store instead of writing an assembled
file — chunk parts persist until finalize, so completion is genuinely
retryable). The legacy blob re-chunk migration streams from the
backend with no spool file either.
Legacy removed: store_from_file + mmap CDC analysers + temp-path
plumbing through every port (pre_computed_hash, save_file_from_temp,
update_file_content_from_temp), upload_spool + assembled-file
assembly in both chunked services, create_file/update_file byte-slice
variants (no callers), common::temp, the OXICLOUD_UPLOAD_TMPDIR
config, and the memmap2 dependency.
Verified end-to-end against PostgreSQL 16: 8 MB upload (26 chunks),
identical re-upload (dedup hit, zero writes), 3-byte edit re-upload
(26 chunks, 1 written), byte-identical downloads, Range across chunk
boundaries, concurrent identical-upload race (manifest ref 2), and
trash-empty reclaiming exactly the unshared chunk while the shared 25
survive for the edited file. The empty/sub-8KB multipart path found a
post-EOF re-poll panic in the MIME peek (fixed with fuse + regression
test).

ensure files does not exeed OXICLOUD_MAX_UPLOAD_SIZE, prefer to deny from header rather consuming bandwidth
add OXICLOUD_DIRECT_PUT_MAX_BYTES for direct PUT (non chunked), admins can fine tune their prefered values
explain OXICLOUD_CHUNK_DIR and OXICLOUD_UPLOAD_TMPDIR
and also the OXICLOUD_CHUNK_MAX_BYTES & OXICLOUD_UPLOAD_TMPDIR
to help administratorrs to defined correctly their storage architecture
- add coalesced protection to avoid mail bombing if an invited goes many grant in a short period
- add resentd method in share menu item (work for both internal and external users)
- user can disable email notification via his properties
- add env variable from admin to disable notifications
- remove the hardcoded list of locales in favor of a discovry on start time
- server will stop on badly formatted locale .json
- add server.* entries for serer side translation
server side translation will be used for templating and email
note: no json in some embded html (like in /magic), amount of work was similar
- SMTP has a mock to enable end to end test and validate the whole path
(via OXICLOUD_SMTP_MOCK)
- add email normalisation ( including punicode)
- api to share to external user
initially server was accepting multiple instances on same port (Linux and MacOS only)
this can create issues during development (if a dev forget another running instance...)
Add OXICLOUD_REUSE_PORT variable to activate it, so only admins knowing this feature can activate itt
(permits multiple instance + let the OS schedduler to decide which process will handle a request)
if not enabled, other instance will receive exit with a:
`Error: Os { code: 48, kind: AddrInUse, message: "Address already in use" }`
