Introducing gowrap as a build-time tool to generate interface delegate
structs from templates:
* added as a 'make go-generate' target in services/graph,
* added as a build-time dependency in .bingo/
Introduce an LDAP client abstraction interface to be able to wrap the
go-ldap client API with metrics transparently (and possibly hooks and
such in the future), in order to use delegation patterns to measure the
time LDAP (client) operations take to finish, as well as to track their
results (success, failure, not-found).
Has two implementations that are generated using gowrap:
* a go-ldap adapter implementation that directly delegates to a go-ldap
connection
* a time measuring and metrics collecting implementation that delegates
to another LdapClient
The metrics collecting one is disabled by default, can be enabled with
GRAPH_LDAP_METRICS_DISABLE=false
It collects durations of outbound LDAP client operations into a histogram, as
well as the number of concurrent outbound LDAP operations in a gauge (via an
atomic int and a gauge function, as that performs best).
Add an HTTP middleware that measures how long Graph HTTP API requests
take, storing taken time into a histogram along with labels for
* method,
* path pattern (from the chi routes),
* Graph API version prefix,
* Graph API resource name,
* and the resulting status code.
It also tracks the number of concurrent inbound Graph API HTTP requests
using a gauge (also using an atomic int and a gauge function).
Disabled by default, can be enabled with
GRAPH_HTTP_METRICS_DISABLE=false
Add Backend and EducationBackend delegate implementations that measure
execution time on the level of the higher API call operations there
(CreateUser, DeleteUser, ..., CreateSchool, ...), generated using
gowrap.
Disabled by default, can be enabled with
GRAPH_IDENTITY_BACKEND_METRICS_DISABLE=false
Also added a small k6 script to produce some read-only load on the Graph
API, for a casual test of the metrics, as well as k6 in mise.toml.
Make an internal changes to how singular LDAP entry searches work in the LDAP
identity backends:
* check whether searches for a singular entry returns more than one
result, in which case a new error TooManyResults is returned, instead
of leaving that undetected, blindly taking the first result, and
potentially risking data inconsistencies
Improve the loggers in identity backends by adding attributes for their
request targets (Reva gateway address or LDAP URI, respectively).
Also add a "backend" attribute for all Graph API logs (set to "ldap" or
"cs3"), to help debug potential issues, and remove them from all the logger
debug calls at the beginning of each LDAP-related function as those should
really be part of the logger and set beforehand.
The LDAP identity backend logger also has two new attributes to help
debugging with logs:
* write (bool): whether write operations are enabled
* refint (bool): whether refint is enabled or not
Also adds a dedicated counter metric for user password change operations.
Minor campfire improvements:
* add a constructor func for the CS3 backend
* add a constructor func for the LDAP backend
* in the LDAP identity backend, in searchLDAPEntryByFilter (used by all
search/get public functions), errors that occur when performing LDAP
SEARCH operations were blindly mapped to a ItemNotFound error,
instead of being analyzed as it could be caused by a technical error
* in the requireadmin middleware, add debug logging to explain why a
request is denied
* when an LDAP password change fails because the user entry was not
found in LDAP, we now have a log message that tracks that
* feature: add beta drive listing endpoints to the graph api and hydrate them to contain the new grantedtoV2 property and use unified roles instead of the cs3 roles
* enhancement: make use of owner conditions for drive listing
* enhancement: provide GetDrivesV1Beta1 and GetAllDrivesV1Beta1 graph endpoint tests
* enhancement: add graph beta listPermissions endpoint
besides the new api endpoint it includes several utilities to simplify the graph api development.
* resolve drive and item id from the request path
* generic pointer and value utilities
* space root detection
* update GetDriveAndItemIDParam signature to return a error
* move errorcode package
* enhancement: add generic error code handling
* fix: rebase
