That distinction makes no sense. Non-special-const objects (including `String`) are always shown in pointer reference form. That `"0x007f8f3c8baf88"` is the content of a string but not the pointer, then it never appears with your patch. ---------------------------------------- Feature #11599: Dump entries of hash in ObjectSpace https://bugs.ruby-lang.org/issues/11599#change-54481 * Author: Yosi Attias * Status: Open * Priority: Normal * Assignee: ---------------------------------------- Hi, *This is my first c code contribution :)* I am helping developing heap-analyzer (github.com/tenderlove/heap-analyzer), and currently the dumps lacks of "type metadata" information, like: * Hash entries - the keys and value * Array items - the items of the array etc. In the included patch, I have changed the dump of hash to add entries of hash. For example, given the next hash: ~~~ruby hash = { int_key: 1, str_key: "This is my string", inner_hash: { b: 2 } } ~~~ The dump result (ObjectSpace.dump(hash)) will be: ~~~json { "address": "0x007fbc01110340", "type": "HASH", "class": "0x007fbc0109b400", "size": 3, "entries": [ { "is_key_address": false, "key": ":int_key", "is_value_address": false, "value": "1" }, { "is_key_address": false, "key": ":str_key", "is_value_address": true, "value": "0x007fbc01110390" }, { "is_key_address": false, "key": ":inner_hash", "is_value_address": true, "value": "0x007fbc01110368" } ], "references": [ "0x007fbc01110390", "0x007fbc01110368" ], "memsize": 232, "flags": { "wb_protected": true } } ~~~ As you can see, I have the "entries" array, where each entry contains: "is_key_address", "is_value_address" - if the key/value are special consts the inspected value will be printed in the "key"/"value" properties, other their address will be print. Hope you will accept the patch (and I can submit another one for arrays), Yosi. ---Files-------------------------------- objspace_dump_hash_entries.patch (4.8 KB) -- https://bugs.ruby-lang.org/
