Details

• Bugfix #1815: Drone CI - patch the 'store-dev-release' job to fix malformed requests

  Replace the backquotes that were used for the date component of the URL with the
  POSIX-confirmant command substitution '$()'.

  #1815

• Bugfix #1765: 'golang:alpine' as base image & CGO_ENABLED just for the CLI

  Some of the dependencies used by revad need CGO to be enabled in order to work. We also need to
  install the 'mime-types' in alpine to correctly detect them on the storage-providers.

  The CGO_ENABLED=0 flag was added to the docker build flags so that it will produce a static
  build. This allows usage of the 'scratch' image for reduction of the docker image size (e.g. the
  reva cli).

  #1765
  #1766
  #1797

• Change #1721: Absolute and relative references

  We unified the Reference_Id end Reference_Path types to a combined Reference that
  contains both: - a resource_id property that can identify a node using a storage_id and an
  opaque_id - a path property that can be used to represent absolute paths as well as paths
  relative to the id based properties. While this is a breaking change it allows passing both:
  absolute as well as relative references.

  #1721

• Enhancement #1810: Add arbitrary metadata support to EOS

  #1810

• Enhancement #1774: Add user ID cache warmup to EOS storage driver

  #1774

• Enhancement #1471: EOEGrpc progress. Logging discipline and error handling

  #1471

• Enhancement #1811: Harden public shares signing

  Makes golangci-lint happy as well

  #1811

• Enhancement #1793: Remove the user id from the trashbin key

  We don't want to use the users uuid outside of the backend so I removed the id from the trashbin
  file key.

  #1793

• Enhancement #1795: Increase trashbin restore API compatibility

  • The precondition were not checked before doing a trashbin restore in the ownCloud dav API.
    Without the checks the API would behave differently compared to the oC10 API. * The restore
    response was missing HTTP headers like ETag * Update the name when restoring the file from
    trashbin to a new target name

  #1795

• Enhancement #1516: Use UidNumber and GidNumber fields in User objects

  Update instances where CS3API's User objects are created and used to use GidNumber, and
  UidNumber fields instead of storing them in Opaque map.

  #1516

• Enhancement #1820: Tag v1.9.0

  Bump release number to v1.9.0 as it contains breaking changes related to changing the
  reference type.

  #1820

Details

• Bugfix #1779: Set Content-Type header correctly for ocs requests

  Before this fix the Content-Type header was guessed by w.Write because WriteHeader was
  called to early. Now the Content-Type is set correctly and to the same values as in ownCloud 10

  owncloud/ocis#1779

• Bugfix #1650: Allow fetching shares as the grantee

  The json backend now allows a grantee to fetch a share by id.

  #1650

• Bugfix #1693: Fix move in owncloud storage driver

  When moving a file or folder (includes renaming) the filepath in the cache didn't get updated
  which caused subsequent requests to getpath to fail.

  #1693
  #1696

• Bugfix #1666: Fix public file shares

  Fixed stat requests and propfind responses for publicly shared files.

  #1666

• Bugfix #1541: Allow for restoring recycle items to different locations

  The CS3 APIs specify a way to restore a recycle item to a different location than the original by
  setting the restore_path field in the RestoreRecycleItemRequest. This field had not
  been considered until now.

  #1541
  https://cs3org.github.io/cs3apis/

• Bugfix #1718: Use the -static ldflag only for the 'build-ci' target

  It is not intended to statically link the generated binaries for local development workflows.
  This resulted on segmentation faults and compiller warnings.

  #1718

• Enhancement #1719: Application passwords CLI

  This PR adds the CLI commands token-list, token-create and token-remove to manage
  tokens with limited scope on behalf of registered users.

  #1719

• Enhancement #1719: Application passwords management

  This PR adds the functionality to generate authentication tokens with limited scope on behalf
  of registered users. These can be used in third party apps or in case primary user credentials
  cannot be submitted to other parties.

  #1714
  #1719
  cs3org/cs3apis#127

• Enhancement #1725: Create transfer type share

  transfer-create creates a share of type transfer.

  #1725

• Enhancement #1755: Return file checksum available from the metadata for the EOS driver

  #1755

• Enhancement #1673: Deprecate using errors.New and fmt.Errorf

  Previously we were using errors.New and fmt.Errorf to create errors. Now we use the errors
  defined in the errtypes package.

  #1673

• Enhancement #1723: Open in app workflow using the new API

  This provides a new open-in-app command for the CLI and the implementation on the
  appprovider gateway service for the new API, including the option to specify the appplication
  to use, thus overriding the preconfigured one.

  #1723

• Enhancement #1655: Improve json marshalling of share protobuf messages

  Protobuf oneof fields cannot be properly handled by the native json marshaller, and the
  protojson package can only handle proto messages. Previously, we were using a workaround of
  storing these oneof fields separately, which made the code inelegant. Now we marshal these
  messages as strings before marshalling them via the native json package.

  #1655

• Enhancement #1694: User profile picture capability

  Based on feedback in the new ownCloud web frontend we want to omit trying to render user avatars
  images / profile pictures based on the backend capabilities. Now the OCS communicates a
  corresponding value.

  #1694

• Enhancement #1649: Add reliability calculations support to Mentix

  To make reliability calculations possible, a new exporter has been added to Mentix that reads
  scheduled downtimes from the GOCDB and exposes it through Prometheus metrics.

  #1649

• Enhancement #1509: Named Service Registration

  Move away from hardcoding service IP addresses and rely upon name resolution instead. It
  delegates the address lookup to a static in-memory service registry, which can be
  re-implemented in multiple forms.

  #1509

• Enhancement #1643: Cache resources from share getter methods in OCS

  In OCS, once we retrieve the shares from the shareprovider service, we stat each of those
  separately to obtain the required info, which introduces a lot of latency. This PR introduces a
  resoource info cache in OCS, which would prevent this latency.

  #1643

• Enhancement #1664: Add cache warmup strategy for OCS resource infos

  Recently, a TTL cache was added to OCS to store statted resource infos. This PR adds an interface
  to define warmup strategies and also adds a cbox specific strategy which starts a goroutine to
  initialize the cache with all the valid shares present in the system.

  #1664

• Enhancement #1710: Owncloudsql storage driver

  This PR adds a storage driver which connects to a oc10 storage backend (storage + database).
  This allows for running oc10 and ocis with the same backend in parallel.

  #1710

• Enhancement #1705: Reduce the size of all the container images built on CI

  Previously, all images were based on golang:1.16 which is built from Debian. Using 'scratch'
  as base, reduces the size of the artifacts well as the attack surface for all the images, plus
  copying the binary from the build step ensures that only the strictly required software is
  present on the final image. For the revad images tagged '-eos', eos-slim is used instead. It is
  still large but it updates the environment as well as the EOS version.

  #1705

• Enhancement #1669: Mint scope-based access tokens for RBAC

  Primarily, this PR is meant to introduce the concept of scopes into our tokens. At the moment, it
  addresses those cases where we impersonate other users without allowing the full scope of what
  the actual user has access to.

  A short explanation for how it works for public shares: - We get the public share using the token
  provided by the client. - In the public share, we know the resource ID, so we can add this to the
  allowed scope, but not the path. - However, later OCDav tries to access by path as well. Now this
  is not allowed at the moment. However, from the allowed scope, we have the resource ID and we're
  allowed to stat that. We stat the resource ID, get the path and if the path matches the one passed
  by OCDav, we allow the request to go through.

  #1669

• Enhancement #1683: Filter created shares based on type in OCS

  #1683

• Enhancement #1763: Sort share entries alphabetically

  When showing the list of shares to the end-user, the list was not sorted alphabetically. This PR
  sorts the list of users and groups.

  #1763

• Enhancement #1758: Warn user for not recommended go version

  This PR adds a warning while an user is building the source code, if he is using a go version not
  recommended.

  #1758
  #1760

• Enhancement #1747: Add checksum headers to tus preflight responses

  Added checksum to the header Tus-Extension and added the Tus-Checksum-Algorithm
  header.

  owncloud/ocis#1747
  #1702

• Enhancement #1685: Add share to update response

  After accepting or rejecting a share the API includes the updated share in the response.

  #1685
  #1724

Details

• Bugfix #1619: Fixes for enabling file sharing in EOS

  #1619

• Bugfix #1576: Fix etag changing only once a second

  We fixed a problem with the owncloud storage driver only considering the mtime with a second
  resolution for the etag calculation.

  #1576

• Bugfix #1634: Mentix site authorization status changes

  If a site changes its authorization status, Mentix did not update its internal data to reflect
  this change. This PR fixes this issue.

  #1634

• Bugfix #1625: Make local file connector more error tolerant

  The local file connector caused Reva to throw an exception if the local file for storing site
  data couldn't be loaded. This PR changes this behavior so that only a warning is logged.

  #1625

• Bugfix #1526: Fix webdav file versions endpoint bugs

  Etag and error code related bugs have been fixed for the webdav file versions endpoint and
  removed from the expected failures file.

  #1526

• Bugfix #1457: Cloning of internal mesh data lost some values

  This update fixes a bug in Mentix that caused some (non-critical) values to be lost during data
  cloning that happens internally.

  #1457

• Bugfix #1597: Check for ENOTDIR on readlink error

  The deconstructed storage driver now handles ENOTDIR errors when node.Child() is called
  for a path containing a path segment that is actually a file.

  owncloud/ocis#1239
  #1597

• Bugfix #1636: Skip file check for OCM data transfers

  #1636

• Bugfix #1552: Fix a bunch of trashbin related issues

  Fixed these issues:

  • Complete: Deletion time in trash bin shows a wrong date - Complete: shared trash status code -
    Partly: invalid webdav responses for unauthorized requests. - Partly: href in trashbin
    PROPFIND response is wrong

  Complete means there are no expected failures left. Partly means there are some scenarios
  left.

  #1552

• Bugfix #1: Bump meshdirectory-web to 1.0.2

  Updated meshdirectory-web mod to version 1.0.2 that contains fixes for OCM invite API links
  generation.

  sciencemesh/meshdirectory-web#1

• Change #1562: Modularize api token management in GRAPPA drivers

  This PR moves the duplicated api token management methods into a seperate utils package

  #1562

• Change #1452: Separate blobs from metadata in the ocis storage driver

  We changed the ocis storage driver to keep the file content separate from the metadata by
  storing the blobs in a separate directory. This allows for using a different (potentially
  faster) storage for the metadata.

  Note This change makes existing ocis storages incompatible with the new code.

  We also streamlined the ocis and the s3ng drivers so that most of the code is shared between them.

  #1452

• Enhancement #1514: Add grpc test suite for the storage provider

  A new test suite has been added which tests the grpc interface to the storage provider. It
  currently runs against the ocis and the owncloud storage drivers.

  #1514

• Enhancement #1466: Add integration tests for the s3ng driver

  We extended the integration test suite to also run all tests against the s3ng driver.

  #1466

• Enhancement #1521: Clarify expected failures

  Some features, while covered by the ownCloud 10 acceptance tests, will not be implmented for
  now: - blacklisted / ignored files, because ocis/reva don't need to blacklist .htaccess
  files - OC-LazyOps support was removed from the
  clients. We are thinking about a state
  machine for uploads to properly solve that scenario and also list the state of files in progress
  in the web ui. The expected failures
  files now have a dedicated Won't fix section for these items.

  owncloud/ocis#214
  #1521
  owncloud/client#8398

• Enhancement #1624: Add wrappers for EOS and EOS Home storage drivers

  For CERNBox, we need the mount ID to be configured according to the owner of a resource. Setting
  this in the storageprovider means having different instances of this service to cater to
  different users, which does not scale. This driver forms a wrapper around the EOS driver and
  sets the mount ID according to a configurable mapping based on the owner of the resource.

  #1624

• Enhancement #1563: Implement cs3.sharing.collaboration.v1beta1.Share.ShareType

  Interface method Share() in pkg/ocm/share/share.go now has a share type parameter.

  #1563

• Enhancement #1411: Make InsecureSkipVerify configurable

  Add InsecureSkipVerify field to metrics.Config struct and update examples to include
  it.

  #1411

• Enhancement #1106: Make command to run litmus tests

  This updates adds an extra make command to run litmus tests via make. make litmus-test
  executes the tests.

  #1106
  #1543

• Enhancement #1502: Bump meshdirectory-web to v1.0.4

  Updated meshdirectory-web version to v.1.0.4 bringing multiple UX improvements in provider
  list and map.

  #1502
  sciencemesh/meshdirectory-web#2
  sciencemesh/meshdirectory-web#3

• Enhancement #1502: New MeshDirectory HTTP service UI frontend with project branding

  We replaced the temporary version of web frontend of the mesh directory http service with a new
  redesigned & branded one. Because the new version is a more complex Vue SPA that contains image,
  css and other assets, it is now served from a binary package distribution that was generated
  using the github.com/rakyll/statik package. The
  http.services.meshdirectory.static config option was obsoleted by this change.

  #1502

• Enhancement #1405: Quota querying and tree accounting

  The ocs api now returns the user quota for the users home storage. Furthermore, the ocis storage
  driver now reads the quota from the extended attributes of the user home or root node and
  implements tree size accounting. Finally, ocdav PROPFINDS now handle the
  DAV:quota-used-bytes and DAV:quote-available-bytes properties.

  #1405
  #1491

• Enhancement #1527: Add FindAcceptedUsers method to OCM Invite API

  #1527

• Enhancement #1149: Add CLI Commands for OCM invitation workflow

  This adds a couple of CLI commands, ocm-invite-generate and ocm-invite-forward to
  generate and forward ocm invitation tokens respectively.

  #1149

• Enhancement #1629: Implement checksums in the owncloud storage

  Implemented checksums in the owncloud storage driver.

  #1629

• Enhancement #1528: Port drone pipeline definition to starlark

  Having the pipeline definition as a starlark script instead of plain yaml greatly improves the
  flexibility and allows for removing lots of duplicated definitions.

Details

• Bugfix #1425: Align href URL encoding with oc10

  We now use the same percent encoding for URLs in WebDAV href properties as ownCloud 10.

  owncloud/ocis#1120
  owncloud/ocis#1296
  owncloud/ocis#1307
  #1425
  #1472

• Bugfix #1461: Fix public link webdav permissions

  We now correctly render oc:permissions on the root collection of a publicly shared folder
  when it has more than read permissions.

  #1461

• Bugfix #1457: Cloning of internal mesh data lost some values

  This update fixes a bug in Mentix that caused some (non-critical) values to be lost during data
  cloning that happens internally.

  #1457

• Bugfix #1429: Purge non-empty dirs from trash-bin

  This wasn't possible before if the directory was not empty

  #1429

• Bugfix #1408: Get error status from trash-bin response

  Previously the status code was gathered from the wrong response.

  #1408

• Enhancement #1451: Render additional share with in ocs sharing api

  Recipients can now be distinguished by their email, which is rendered as additional info in the
  ocs api for share and file owners as well as share recipients.

  owncloud/ocis#1190
  #1451

• Enhancement #1424: We categorized the list of expected failures

  We categorized all expected failures into File (Basic file management like up and download,
  move, copy, properties, trash, versions and chunking), Sync (Synchronization features
  like etag propagation, setting mtime and locking files), Share (File and sync features in a
  shared scenario), User management (User and group management features) and Other (API,
  search, favorites, config, capabilities, not existing endpoints, CORS and others). The
  Review and fix the tests that have sharing step to work with
  ocis reference has been removed, as we
  now have the sharing category

  owncloud/core#38006
  #1424

• Enhancement #1434: CERNBox REST driver for groupprovider service

  #1434

• Enhancement #1400: Checksum support

  We now support checksums on file uploads and PROPFIND results. On uploads, the ocdav service
  now forwards the OC-Checksum (and the similar TUS Upload-Checksum) header to the storage
  provider. We added an internal http status code that allows storage drivers to return checksum
  errors. On PROPFINDs, ocdav now renders the <oc:checksum> header in a bug compatible way for
  oc10 backward compatibility with existing clients. Finally, GET and HEAD requests now return
  the OC-Checksum header.

  owncloud/ocis#1291
  owncloud/ocis#1316
  #1400
  owncloud/core#38304

• Enhancement #1431: Update npm packages to fix vulnerabilities

  #1431

• Enhancement #1415: Indicate in EOS containers that TUS is not supported

  The OCDAV propfind response previously hardcoded the TUS headers due to which clients such as
  phoenix used the TUS protocol for uploads, which EOS doesn't support. Now we pass this property
  as an opaque entry in the containers metadata.

  #1415

• Enhancement #1402: Parse EOS sys ACLs to generate CS3 resource permissions

  #1402

• Enhancement #1477: Set quota when creating home directory in EOS

  #1477

• Enhancement #1416: Use updated etag of home directory even if it is cached

  We cache the home directory and shares folder etags as calculating these is an expensive
  process. But if these directories were updated after the previously calculated etag was
  cached, we can ignore this calculation and directly return the new one.

  #1416

• Enhancement #1478: Enhance error handling for grappa REST drivers

  #1478

• Enhancement #1453: Add functionality to share resources with groups

  #1453

• Enhancement #99: Add stubs and manager for groupprovider service

  Recently, there was a separation of concerns with regard to users and groups in CS3APIs. This PR
  adds the required stubs and drivers for the group manager.

  cs3org/cs3apis#99
  cs3org/cs3apis#102
  #1358

• Enhancement #1462: Hash public share passwords

  The share passwords were only base64 encoded. Added hashing using bcrypt with configurable
  hash cost.

  #1462

• Enhancement #1464: LDAP driver for the groupprovider service

  #1464

• Enhancement #1430: Capture non-deterministic behavior on storages

  As a developer creating/maintaining a storage driver I want to be able to validate the
  atomicity of all my storage driver operations. * Test for: Start 2 uploads, pause the first one,
  let the second one finish first, resume the first one at some point in time. Both uploads should
  finish. Needs to result in 2 versions, last finished is the most recent version. * Test for:
  Start 2 MKCOL requests with the same path, one needs to fail.

  #1430

• Enhancement #1456: Fetch user groups in OIDC and LDAP backend

  #1456

• Enhancement #1429: Add s3ng storage driver, storing blobs in a s3-compatible blobstore

  We added a new storage driver (s3ng) which stores the file metadata on a local filesystem
  (reusing the decomposed filesystem of the ocis driver) and the actual content as blobs in any
  s3-compatible blobstore.

  #1429

• Enhancement #1467: Align default location for xrdcopy binary

  #1467

• Bugfix #1401: Use the user in request for deciding the layout for non-home DAV requests

  For the incoming /dav/files/userID requests, we have different namespaces depending on
  whether the request is for the logged-in user's namespace or not. Since in the storage drivers,
  we specify the layout depending only on the user whose resources are to be accessed, this fails
  when a user wants to access another user's namespace when the storage provider depends on the
  logged in user's namespace. This PR fixes that.

  For example, consider the following case. The owncloud fs uses a layout {{substr 0 1
  .Id.OpaqueId}}/{{.Id.OpaqueId}}. The user einstein sends a request to access a resource
  shared with him, say /dav/files/marie/abcd, which should be allowed. However, based on the
  way we applied the layout, there's no way in which this can be translated to /m/marie/.

• Bugfix #1413: Re-include the '.git' dir in the Docker images to pass the version tag

  And git SHA to the release tool.

  #1413

• Bugfix #1399: Fix ocis trash-bin purge

  Fixes the empty trash-bin functionality for ocis-storage

  owncloud/product#254
  #1399

• Enhancement #1397: Bump the Copyright date to 2021

  #1397

• Enhancement #1398: Support site authorization status in Mentix

  This enhancement adds support for a site authorization status to Mentix. This way, sites
  registered via a web app can now be excluded until authorized manually by an administrator.

  Furthermore, Mentix now sets the scheme for Prometheus targets. This allows us to also support
  monitoring of sites that do not support the default HTTPS scheme.

  #1398

• Enhancement #1393: Allow setting favorites, mtime and a temporary etag

  We now let the ocis driver persist favorites, set temporary etags and the mtime as arbitrary
  metadata.

  owncloud/ocis#567
  #1394
  #1393

• Enhancement #1403: Support remote cloud gathering metrics

  The current metrics package can only gather metrics either from json files. With this feature,
  the metrics can be gathered polling the http endpoints exposed by the owncloud/nextcloud
  sciencemesh apps.

Details

• Bugfix #1385: Run changelog check only if there are changes in the code

  #1385

• Bugfix #1333: Delete sdk unit tests

  These depend on a remote server running reva and thus fail in case of version mismatches.

  #1333

• Bugfix #1342: Dav endpoint routing to home storage when request is remote.php/dav/files

  There was a regression in which we were not routing correctly to the right storage depending on
  the url.

  #1342

• Bugfix #1338: Fix fd leaks

  There were some left over open file descriptors on simple.go.

  #1338

• Bugfix #1343: Fix ocis move

  Use the old node id to build the target path for xattr updates.

  owncloud/ocis#975
  #1343

• Bugfix #551: Fix purging deleted files with the ocis storage

  The ocis storage could load the owner information of a deleted file. This caused the storage to
  not be able to purge deleted files.

  owncloud/ocis#551

• Bugfix #863: Fix dav api for trashbin

  The api was comparing the requested username to the userid.

  owncloud/ocis#863

• Bugfix #204: Fix the ocs share with me response

  The path of the files shared with me was incorrect.

  owncloud/product#204
  #1346

• Bugfix #1351: Fix xattr.Remove error check for macOS

  Previously, we checked the xattr.Remove error only for linux systems. Now macOS is checked
  also

  #1351

• Bugfix #1320: Do not panic on remote.php/dav/files/

  Currently requests to /remote.php/dav/files/ result in panics since we cannot longer strip
  the user + destination from the url. This fixes the server response code and adds an error body to
  the response.

  #1320

• Bugfix #1379: Make Jaeger agent usable

  Previously, you could not use tracing with jaeger agent because the tracing connector is
  always used instead of the tracing endpoint.

  This PR removes the defaults for collector and tracing endpoint.

  #1379

• Bugfix #1331: Fix capabilities response for multiple client versions

  #1331

• Bugfix #1281: When sharing via ocs look up user by username

  The ocs api returns usernames when listing share recipients, so the lookup when creating the
  share needs to search the usernames and not the userid.

  #1281

• Bugfix #1334: Handle removal of public shares by token or ID

  Previously different drivers handled removing public shares using different means, either
  the token or the ID. Now, both the drivers support both these methods.

  #1334

• Change #990: Replace the user uuid with the username in ocs share responses

  The ocs api should not send the users uuid. Replaced the uuid with the username.

  owncloud/ocis#990
  #1375

• Enhancement #1350: Add auth protocol based on user agent

  Previously, all available credential challenges are given to the client, for example, basic
  auth, bearer token, etc ... Different clients have different priorities to use one method or
  another, and before it was not possible to force a client to use one method without having a side
  effect on other clients.

  This PR adds the functionality to target a specific auth protocol based on the user agent HTTP
  header.

  #1350

• Enhancement #1362: Mark 'store-dev-release' CI step as failed on 4XX/5XX errors

  Prevent the errors while storing new 'daily' releases from going unnoticed on the CI.

  #1362

• Enhancement #1364: Remove expired Link on Get

  There is the scenario in which a public link has expired but ListPublicLink has not run,
  accessing a technically expired public share is still possible.

  #1364

• Enhancement #1340: Add cache to store UID to UserID mapping in EOS

  Previously, we used to send an RPC to the user provider service for every lookup of user IDs from
  the UID stored in EOS. This PR adds an in-memory lock-protected cache to store this mapping.

  #1340

• Enhancement #1154: Add support for the protobuf interface to eos metadata

  #1154

• Enhancement #1154: Merge-rebase from master 10/11/2020

  #1154

• Enhancement #1359: Add cache for calculated etags for home and shares directory

  Since we store the references in the shares directory instead of actual resources, we need to
  calculate the etag on every list/stat call. This is rather expensive so adding a cache would
  help to a great extent with regard to the performance.

  #1359

• Enhancement #1321: Add support for multiple data transfer protocols

  Previously, we had to configure which data transfer protocol to use in the dataprovider
  service. A previous PR added the functionality to redirect requests to different handlers
  based on the request method but that would lead to conflicts if multiple protocols don't
  support mutually exclusive sets of requests. This PR adds the functionality to have multiple
  such handlers simultaneously and the client can choose which protocol to use.

  #1321
  #1285

• Enhancement #1324: Log expected errors with debug level

  While trying to download a non existing file and reading a non existing attribute are
  technically an error they are to be expected and nothing an admin can or even should act upon.

  #1324

• Enhancement #1351: Map errtypes to status

  When mapping errtypes to grpc statuses we now also map bad request and not implemented /
  unsupported cases in the gateway storageprovider.

  #1351

• Enhancement #1347: Support property to enable health checking on a service

  This update introduces a new service property called ENABLE_HEALTH_CHECKS that must be
  explicitly set to true if a service should be checked for its health status. This allows us to
  only enable these checks for partner sites only, skipping vendor sites.

  #1347

• Enhancement #1332: Add import support to Mentix

  This update adds import support to Mentix, transforming it into a Mesh Entity Exchanger.
  To properly support vendor site management, a new connector that works on a local file has been
  added as well.

  #1332

• Enhancement #1371: Use self-hosted Drone CI

  Previously, we used the drone cloud to run the CI for the project. Due to unexpected and sudden
  stop of the service for the cs3org we decided to self-host it.

  #1371

• Enhancement #1354: Map bad request and unimplement to http status codes

  We now return a 400 bad request when a grpc call fails with an invalid argument status and a 501 not
  implemented when it fails with an unimplemented status. This prevents 500 errors when a user
  tries to add resources to the Share folder or a storage does not implement an action.

  #1354

• Enhancement #929: Include share types in ocs propfind responses

  Added the share types to the ocs propfind response when a resource has been shared.

Details

• Bugfix #1316: Fix listing shares for nonexisting path

  When trying to list shares for a not existing file or folder the ocs sharing implementation no
  longer responds with the wrong status code and broken xml.

  #1316

• Bugfix #1274: Let the gateway filter invalid references

  We now filter deleted and unshared entries from the response when listing the shares folder of a
  user.

  #1274

• Bugfix #1269: Handle more eos errors

  We now treat E2BIG, EACCES as a permission error, which occur, eg. when acl checks fail and
  return a permission denied error.

  #1269

• Bugfix #1297: Check the err and the response status code

  The publicfile handler needs to check the response status code to return proper not pound and
  permission errors in the webdav api.

  #1297

• Bugfix #1260: Fix file descriptor leak on ocdav put handler

  File descriptors on the ocdav service, especially on the put handler was leaking http
  connections. This PR addresses this.

  #1260

• Bugfix #1253: Upload file to storage provider after assembling chunks

  In the PUT handler for chunked uploads in ocdav, we store the individual chunks in temporary
  file but do not write the assembled file to storage. This PR fixes that.

  #1253

• Bugfix #1264: Fix etag propagation in ocis driver

  We now use a new synctime timestamp instead of trying to read the mtime to avoid race conditions
  when the stat request happens too quickly.

  owncloud/product#249
  #1264

• Bugfix #1255: Check current node when iterating over path segments

  When checking permissions we were always checking the leaf instead of using the current node
  while iterating over path segments.

  #1255

• Bugfix #1265: Stop setting propagation xattr on new files

  We no longer set the propagation flag on a file because it is only evaluated for folders anyway.

  #1265

• Bugfix #260: Filter share with me requests

  The OCS API now properly filters share with me requests by path and by share status (pending,
  accepted, rejected, all)

  https://github.com/owncloud/ocis-reva/issues/260
  https://github.com/owncloud/ocis-reva/issues/311
  #1301

• Bugfix #1317: Prevent nil pointer when listing shares

  We now handle cases where the grpc connection failed correctly by no longer trying to access the
  response status.

  #1317

• Bugfix #1259: Fix propfind response code on forbidden files

  When executing a propfind to a resource owned by another user the service would respond with a
  HTTP 403. In ownCloud 10 the response was HTTP 207. This change sets the response code to HTTP 207
  to stay backwards compatible.

  #1259

• Bugfix #1294: Fix error type in read node when file was not found

  The method ReadNode in the ocis storage didn't return the error type NotFound when a file was not
  found.

  #1294

• Bugfix #1258: Update share grants on share update

  When a share was updated the share information in the share manager was updated but the grants
  set by the storage provider were not.

  #1258

• Enhancement #1257: Add a test user to all sites

  For health monitoring of all mesh sites, we need a special user account that is present on every
  site. This PR adds such a user to each users-*.json file so that every site will have the same test
  user credentials.

  #1257

• Enhancement #1234: Resolve a WOPI bridge appProviderURL by extracting its redirect

  Applications served by the WOPI bridge (CodiMD for the time being) require an extra
  redirection as the WOPI bridge itself behaves like a user app. This change returns to the client
  the redirected URL from the WOPI bridge, which is the real application URL.

  #1234

• Enhancement #1239: Add logic for finding groups to user provider service

  To create shares with user groups, the functionality for searching for these based on a pattern
  is needed. This PR adds that.

  #1239

• Enhancement #1280: Add a Reva SDK

  A Reva SDK has been added to make working with a remote Reva instance much easier by offering a
  high-level API that hides all the underlying details of the CS3API.

  #1280

• Enhancement #1237: Setup of grpc transfer service and cli

  The grpc transfer service and cli for it.

  #1237

• Enhancement #1224: Add SQL driver for share manager

  This PR adds an SQL driver for the shares manager which expects a schema equivalent to the one
  used in production for CERNBox.

  #1224

• Enhancement #1285: Refactor the uploading files workflow from various clients

  Previously, we were implementing the tus client logic in the ocdav service, leading to
  restricting the whole of tus logic to the internal services. This PR refactors that workflow to
  accept incoming requests following the tus protocol while using simpler transmission
  internally.

  #1285
  #1314

• Enhancement #1233: Add support for custom CodiMD mimetype

  The new mimetype is associated with the .zmd file extension. The corresponding
  configuration is associated with the storageprovider.

  #1233
  #1284

• Enh #1225: Allow setting the owner when using the ocis driver
• Enh #1180: Introduce ocis driver treetime accounting
• Enh #1208: Calculate etags on-the-fly for shares directory and home folder

Details

• Bugfix #1140: Call the gateway stat method from appprovider

  The appprovider service used to directly pass the stat request to the storage provider
  bypassing the gateway, which resulted in errors while handling share children as they are
  resolved in the gateway path.

  #1140

• Bugfix #1170: Up and download of file shares

  The shared folder logic in the gateway storageprovider was not allowing file up and downloads
  for single file shares. We now check if the reference is actually a file to determine if up /
  download should be allowed.

  #1170

• Bugfix #1177: Fix ocis move

  When renaming a file we updating the name attribute on the wrong node, causing the path
  construction to use the wrong name. This fixes the litmus move_coll test.

  #1177

• Bugfix #1178: Fix litmus failing on ocis storage

  We now ignore the no data available error when removing a non existing metadata attribute,
  which is ok because we are trying to delete it anyway.

  #1178
  #1179

• Bugfix #237: Fix missing quotes on OCIS-Storage

  Etags have to be enclosed in quotes ". Return correct etags on OCIS-Storage.

  owncloud/product#237
  #1232

• Bugfix #1210: No longer swallow permissions errors in the gateway

  The gateway is no longer ignoring permissions errors. It will now check the status for
  rpc.Code_CODE_PERMISSION_DENIED codes and report them properly using
  status.NewPermissionDenied or status.NewInternal instead of reusing the original
  response status.

  #1210

• Bugfix #1183: Handle eos EPERM as permission denied

  We now treat EPERM errors, which occur, eg. when acl checks fail and return a permission denied
  error.

  #1183

• Bugfix #1206: No longer swallow permissions errors

  The storageprovider is no longer ignoring permissions errors. It will now report them
  properly using status.NewPermissionDenied(...) instead of status.NewInternal(...)

  #1206

• Bugfix #1207: No longer swallow permissions errors in ocdav

  The ocdav api is no longer ignoring permissions errors. It will now check the status for
  rpc.Code_CODE_PERMISSION_DENIED codes and report them properly using
  http.StatusForbidden instead of http.StatusInternalServerError

  #1207

• Bugfix #1161: Cache display names in ocs service

  The ocs list shares endpoint may need to fetch the displayname for multiple different users. We
  are now caching the lookup fo 60 seconds to save redundant RPCs to the users service.

  #1161

• Bugfix #1216: Add error handling for invalid references

  #1216
  #1218

• Enhancement #1205: Allow using the username when accessing the users home

  We now allow using the userid and the username when accessing the users home on the /dev/files
  endpoint.

  #1205

• Enhancement #1131: Use updated cato to display nested package config in parent docs

  Previously, in case of nested packages, we just had a link pointing to the child package. Now we
  copy the nested package's documentation to the parent itself to make it easier for devs.

  #1131

• Enhancement #1213: Check permissions in ocis driver

  We are now checking grant permissions in the ocis storage driver.

  #1213

• Enhancement #1202: Check permissions in owncloud driver

  We are now checking grant permissions in the owncloud storage driver.

  #1202

• Enhancement #1228: Add GRPC stubs for CreateSymlink method

  #1228

• Enhancement #1174: Add logic in EOS FS for maintaining same inode across file versions

  This PR adds the functionality to maintain the same inode across various versions of a file by
  returning the inode of the version folder which remains constant. It requires extra metadata
  operations so a flag is provided to disable it.

  #1174.

• Enhancement #1142: Functionality to map home directory to different storage providers

  We hardcode the home path for all users to /home. This forbids redirecting requests for
  different users to multiple storage providers. This PR provides the option to map the home
  directories of different users using user attributes.

  #1142

• Enhancement #1190: Add Blackbox Exporter support to Mentix

  This update extends Mentix to export a Prometheus SD file specific to the Blackbox Exporter
  which will be used for initial health monitoring. Usually, Prometheus requires its targets to
  only consist of the target's hostname; the BBE though expects a full URL here. This makes
  exporting two distinct files necessary.

  #1190

• Enhancement #1229: New gateway datatx service

  Represents the CS3 datatx module in the gateway.

  #1229

• Enhancement #1225: Allow setting the owner when using the ocis driver

  To support the metadata storage we allow setting the owner of the root node so that subsequent
  requests with that owner can be used to manage the storage.

  #1225

• Enhancement #1180: Introduce ocis driver treetime accounting

  We added tree time accounting to the ocis storage driver which is modeled after eos synctime
  accounting.
  It can be enabled using the new treetime_accounting option, which defaults to false The
  tmtime is stored in an extended attribute user.ocis.tmtime. The treetime accounting is
  enabled for nodes which have the user.ocis.propagation extended attribute set to "1".
  Currently, propagation is in sync.

  #1180

• Enhancement #1208: Calculate etags on-the-fly for shares directory and home folder

  We create references for accepted shares in the shares directory, but these aren't updated
  when the original resource is modified. This PR adds the functionality to generate the etag for
  the shares directory and correspondingly, the home directory, based on the actual resources
  which the references point to, enabling the sync functionality.

  #1208

v1.2.1

Changelog for reva 1.2.1 (2020-09-15)

The following sections list the changes in reva 1.2.1 relevant to
reva users. The changes are ordered by importance.

Summary

• Fix #1124: Do not swallow 'not found' errors in Stat
• Enh #1125: Rewire dav files to the home storage
• Enh #559: Introduce ocis storage driver
• Enh #1118: Metrics module can be configured to retrieve metrics data from file

Details

• Bugfix #1124: Do not swallow 'not found' errors in Stat

  Webdav needs to determine if a file exists to return 204 or 201 response codes. When stating a non
  existing resource the NOT_FOUND code was replaced with an INTERNAL error code. This PR passes
  on a NOT_FOUND status code in the gateway.

  #1124

• Enhancement #1125: Rewire dav files to the home storage

  If the user specified in the dav files URL matches the current one, rewire it to use the
  webDavHandler which is wired to the home storage.

  This fixes path mapping issues.

  #1125

• Enhancement #559: Introduce ocis storage driver

  We introduced a now storage driver ocis that deconstructs a filesystem and uses a node first
  approach to implement an efficient lookup of files by path as well as by file id.

  #559

• Enhancement #1118: Metrics module can be configured to retrieve metrics data from file

  • Export site metrics in Prometheus #698

• Enh #1094: Add logic for resolving storage references over webdav

Details

• Bugfix #1099: Do not restore recycle entry on purge

  This PR fixes a bug in the EOSFS driver that was restoring a deleted entry when asking for its
  permanent purge. EOS does not have the functionality to purge individual files, but the whole
