* the JMAP error handling was not working properly, fixed it and added
error definitions accordingly
* add operations to retrieve mailbox roles and mailboxes by role for
all accounts
* introduce a function 'mcid' to assemble method call IDs per account
instead of doing that inline in each function, in case the rules for
doing so change in the future
* move jmap.request() to jmap.Client.request() and pass the Session
and a Logger to introduce checking the number of methodCalls within a
request not exceeding the limit of the Session, as well as error
handling and logging there instead of in each caller
* a few bugfixes:
- add a few missing Send() calls in logs
- correct the response tag matching for
GetMailboxChangesForMultipleAccounts
- fix typo in Identity.ReplyTo json serialization rune
- fix response tag in pkg/jmap/testdata/mailboxes1.json after
changing them to be prefixed by the accountId
* implement correct Etag and If-None-Match handling, responding with
304 Not Modified if they match
* introduce SessionState and State string type aliases to ensure we are
using the correct fields for those, respectively
* extract the SessionState from the JMAP response bodies in the
groupware framework instead of having to do that in every single
groupware API
* use uint instead of int in some places to clarify that the values are
>= 0
* trace-log how long a Session was held in cache before being evicted
* add Trace-Id header handling: add to response when specified in
request, and implement a custom request logger to include it as a
field
* implement a more compact trace-logging of all the methods and URIs
that are served, to put them into a single log entry instead of
creating one log entry for every URI
* add a GET /accounts/{a}/boostrap URI that delivers the same as GET /
but also mailboxes for a given account, in case the UI remembers the
last used account identifier, to avoid an additional roundtrip
* streamline the use of simpleError()
* add logging of errors at the calling site
* add logging of evictions of Sessions from the cache
* change default Session cache TTL to 5min instead of 30sec
* ensure that all the jmap responses contain the SessionState
* implement missing errors that were marked as TODO
* moved common functions from pkg/jmap and pkg/services/groupware to
pkg/log and pkg/structs to commonalize them across both source trees
* implement error handling for SetError occurences
* Email: replace anonymous map[string]bool for mailbox rights with a
MailboxRights struct, as the keys are well-defined, which allows for
properly documenting them
* introduce ObjectType as an "enum"
* fix JSON marshalling and unmarshalling of EmailBodyStructure
* move the swagger documentation structs from groupware_api.go to
groupware_docs.go
* fix: change verb for /groupware/accounts/*/vacation from POST to PUT
* refactored the models to be strongly typed with structs and mapstruct
to decompose the dynamic parts of the JMAP payloads
* externalized large JSON strings for tests into .json files under
testdata/
* added a couple of fantasy Graph groupware APIs to explore further
options
* added k6 scripts to test those graph/me/messages APIs, with a setup
program to set up users in LDAP, fill their IMAP inbox, activate them
in Stalwart, cleaning things up, etc...
