       # JMAP Library Implementation

     

       2

       +

       This is an OCaml implementation of the JMAP (JSON Meta Application Protocol) as defined in RFC 8620.

     

       4

       +

       ## Design Philosophy

     

       6
       6
       +
       

     

       7
       7
       +
       The library uses **type-safe GADTs** to ensure compile-time correctness of JMAP method calls. Each method has a witness type that pairs argument and response types together.

     

       8
       8
       +

       ## Important: Testing Guidelines

     

       10
       10
       +
       

     

       11
       11
       +
       **NEVER build JSON directly in tests.** The whole point of this library is to provide a type-safe API that abstracts away JSON details.

     

       12
       12
       +
       

     

       13
       13
       +
       ### ❌ Bad - Building JSON manually:

     

       14
       14
       +
       ```ocaml

     

       15
       15
       +
       let request_json = `O [

     

       16
       16
       +
         ("using", `A [`String "urn:ietf:params:jmap:core"; `String "urn:ietf:params:jmap:mail"]);

     

       17
       17
       +
         ("methodCalls", `A [

     

       18
       18
       +
           `A [

     

       19
       19
       +
             `String "Email/query";

     

       20
       20
       +
             `O [("accountId", `String account_id); ("limit", `Float 10.)];

     

       21
       21
       +
             `String "c1"

     

       22
       22
       +
           ]

     

       23
       23
       +
         ])

     

       24
       24
       +
       ] in

     

       25
       25
       +
       let req = Jmap_core.Jmap_request.Parser.of_json request_json in

     

       26
       26
       +
       ```

     

       27
       27
       +
       

     

       28
       28
       +
       ### ✅ Good - Using the JMAP library API:

     

       29
       29
       +
       ```ocaml

     

       30
       30
       +
       (* Build query arguments *)

     

       31

       +
         ("limit", `Float 10.);

     

       34
       34
       +
         ("sort", `A [`O [("property", `String "receivedAt"); ("isAscending", `Bool false)]]);

     

       35
       35
       +
         ("calculateTotal", `Bool true);

     

       36
       36
       +
       ] in

     

       37
       37
       +
       

     

       38
       38
       +
       (* Create invocation using Echo witness for generic JSON *)

     

       39
       39
       +
       let invocation = Jmap_invocation.Invocation {

     

       40
       40
       +
         method_name = "Email/query";

         arguments = query_args;

         call_id = "c1";

     

       43
       43
       +
         witness = Jmap_invocation.Echo;

     

       44
       44
       +
       } in

     

       45
       45

       46

       (* Build request using constructors *)

     

       47

       +
       ### Jmap_request

     

       62
       62
       +
       Build JMAP requests using `Jmap_request.make`:

     

       63
       63
       +
       ```ocaml

     

       64
       64
       +
       val make :

     

       65
       65
       +
         ?created_ids:(Jmap_id.t * Jmap_id.t) list option ->

     

       66
       66
       +
         using:Jmap_capability.t list ->

     

       67
       67
       +
         Jmap_invocation.invocation_list ->

     

       68
       68
       +
         t

     

       69
       69
       +
       ```

     

       70
       70
       +
       

     

       71
       71
       +
       ### Jmap_invocation

     

       72
       72
       +
       Type-safe method invocations using GADT witnesses:

     

       73
       73
       +
       ```ocaml

     

       74
       74
       +
       type ('args, 'resp) method_witness =

     

       75
       75
       +
         | Echo : (Ezjsonm.value, Ezjsonm.value) method_witness

     

       76
       76
       +
         | Get : string -> ('a Get.request, 'a Get.response) method_witness

     

       77
       77
       +
         | Query : string -> ('f Query.request, Query.response) method_witness

     

       78
       78
       +
         (* ... other methods *)

     

       79
       79
       +
       ```

     

       80
       80
       +
       

     

       81
       81
       +
       For generic JSON methods, use the Echo witness. For typed methods, use the appropriate witness.

     

       82
       82
       +
       

     

       83
       83
       +
       ### Jmap_capability

     

       84
       84
       +
       Use predefined capability constants:

     

       85
       85
       +
       ```ocaml

     

       86
       86
       +
       let caps = [Jmap_capability.core; Jmap_capability.mail]

     

       87
       87
       +
       ```

     

       88
       88
       +
       

     

       89
       89
       +
       Or create from URN strings:

     

       90
       90
       +
       ```ocaml

     

       91
       91
       +
       let cap = Jmap_capability.of_string "urn:ietf:params:jmap:core"

     

       92
       92
       +
       ```

     

       93
       93
       +
       

     

       94
       94
       +
       ## Testing Against Real Servers

     

       95
       95
       +
       

     

       96
       96
       +
       See `jmap/test/test_fastmail.ml` for an example of connecting to a real JMAP server (Fastmail).

     

       97
       97
       +
       

     

       98
       98
       +
       The test:

     

       99
       99
       +
       1. Reads API token from `jmap/.api-key` (or other default locations)

     

       100
       100
       +
       2. Creates a connection with Bearer auth

     

       101
       101
       +
       3. Fetches the JMAP session

     

       102
       102
       +
       4. Builds and sends a query request using the library API

     

       103
       103
       +
       5. Parses the response

     

       104
       104
       +
       

     

       105
       105
       +
       ## Current Limitations

     

       106
       106
       +
       

     

       107
       107
       +
       - Full typed method support is partially implemented

     

       108
       108
       +
       - Some methods still use Echo witness with raw JSON arguments

     

       109
       109
       +
       - Response parsing extracts raw JSON rather than fully typed responses

     

       110
       110
       +
       

     

       111
       111
       +
       These will be improved as the library matures.

       ### ⚠️ Known Issue: TLS Connection Reuse

     

       13
       13
       +
       

     

       14
       14
       +
       **Problem**: The Requests library has a bug where making multiple HTTPS requests with the same Requests instance causes a TLS error on the second request:

     

       15
       15
       +
       ```

     

       16
       16
       +
       Fatal error: exception TLS failure: unexpected: application data

     

       17
       17
       +
       ```

     

       18
       18
       +
       

     

       19
       19
       +
       **Reproduction**: 

     

       20
       20
       +
       ```ocaml

     

       21
       21
       +
       let requests = Requests.create ~sw env in

     

       22
       22
       +
       let resp1 = Requests.get requests "https://api.fastmail.com/jmap/session" in

     

       23
       23
       +
       (* Drain body *)

     

       24
       24
       +
       let resp2 = Requests.get requests "https://api.fastmail.com/jmap/session" in

     

       25
       25
       +
       (* ^ Fails with TLS error *)

     

       26
       26
       +
       ```

     

       27
       27
       +
       

     

       28
       28
       +
       **Impact**: The first HTTP request (session fetch) works fine, but any subsequent requests fail.

     

       29
       29
       +
       

     

       30
       30
       +
       **Root Cause**: Issue in Requests library's connection pooling or TLS state management when reusing connections.

     

       31
       31
       +
       

     

       32
       32
       +
       **Workaround Options**:

     

       33
       33
       +
       1. Create a new Requests instance for each request (inefficient)

     

       34
       34
       +
       2. Fix the Requests library's TLS connection handling

     

       35
       35
       +
       3. Disable connection pooling if that option exists

     

       36
       36
       +
       

     

       37
       37
       +
       **Test Case**: `jmap/test/test_simple_https.ml` demonstrates the issue

     

       38
       38
       +

       ### test_fastmail.exe

     

       42
       42
       +
       - ✅ Session parsing works

     

       43
       43
       +
       - ✅ First HTTPS request succeeds

     

       44
       44
       +
       - ❌ Second HTTPS request fails with TLS error

     

       45
       45
       +
       - Status: **Blocked on Requests library bug**

     

       46

       +
       

     

       47
       47
       +
       ### What Works

     

       48
       48
       +
       - Eio integration ✅

     

       49
       49
       +
       - Session fetching and parsing ✅  

     

       50
       50
       +
       - Request building ✅

     

       51
       51
       +
       - JSON serialization/deserialization ✅

     

       52
       52
       +
       - API key loading ✅

     

       53
       53
       +
       - Authentication headers ✅

     

       54
       54
       +
       

     

       55
       55
       +
       ### What's Blocked

     

       56
       56
       +
       - Making JMAP API calls (requires multiple HTTPS requests)

     

       57
       57
       +
       - Email querying

     

       58
       58
       +
       - Full end-to-end testing

     

       59
       59
       +
       

     

       60
       60
       +
       ## Next Steps

     

       61
       61
       +
       

     

       62
       62
       +
       1. Fix TLS connection reuse in Requests library

     

       63
       63
       +
       2. Implement Response.Parser.of_json once requests work

     

       64
       64
       +
       3. Complete end-to-end test with email querying
