This patchset fixes some issues with Android GATT testing, a minor
issue with Android GATT exposed by the shim, and provides a
GAttrib shim using bt_att.
Passes all android/android-tester, unit/test-gattrib
Michael Janssen (4):
android/tester-gatt: DRY/bugfix search single PDUs
android/tester-gatt: deduplicate read-by-type PDUs
android/gatt: dummy callback for indications
GATT shim to src/shared bt_att

To convert it into the format expected by GAttrib, he copied "pdu" in to "buf" which is one byte larger. So, the code is technically correct if not very readable. Michael, please add a comment here to explain why this is OK. If you're checking "length", then maybe assign from "pdu[3]" instead of "buf" for consistency, and explain above why you're doing a memcpy to "buf + 1". >> + status = BT_ATT_ERROR_UNLIKELY; >> + else >> + status = buf[4]; >> } >> >> - cmd->sent = true; >> - >> - if (attrib->timeout_watch == 0) >> - attrib->timeout_watch = g_timeout_add_seconds(GATT_TIMEOUT, >> - disconnect_timeout, attrib); >> + if (cb->result_func) >> + cb->result_func(status, buf, length+1, cb->user_data); >> >> - return FALSE; >> + g_free(buf); >> } >> >> -static void destroy_sender(gpointer data) >> -{ >> - struct _GAttrib *attrib = data; >> >> - attrib->write_watch = 0; >> - g_attrib_unref(attrib); >> -} >> - >> -static void wake_up_sender(struct _GAttrib *attrib) >> -{ >> - if (attrib->write_watch > 0) >> - return; >> - >> - attrib = g_attrib_ref(attrib); >> - attrib->write_watch = g_io_add_watch_full(attrib->io, >> - G_PRIORITY_DEFAULT, G_IO_OUT, >> - can_write_data, attrib, destroy_sender); >> -} >> - >> -static bool match_event(struct event *evt, const uint8_t *pdu, gsize len) >> -{ >> - guint16 handle; >> - >> - if (is_request(pdu[0]) && evt->expected == GATTRIB_ALL_REQS) >> - return true; >> - >> - if (evt->expected == pdu[0] && evt->handle == GATTRIB_ALL_HANDLES) >> - return true; >> - >> - if (len < 3) >> - return false; >> - >> - handle = get_le16(&pdu[1]); >> - >> - if (evt->expected == pdu[0] && evt->handle == handle) >> - return true; >> - >> - return false; >> -} >> - >> -static gboolean received_data(GIOChannel *io, GIOCondition cond, gpointer >> data) +static void attrib_callback_notify(uint8_t opcode, const void *pdu, >> + uint16_t length, void *user_data) >> { >> - struct _GAttrib *attrib = data; >> - struct command *cmd = NULL; >> - GSList *l; >> - uint8_t buf[512], status; >> - gsize len; >> - GIOStatus iostat; >> - >> - if (attrib->stale) >> - return FALSE; >> - >> - if (cond & (G_IO_HUP | G_IO_ERR | G_IO_NVAL)) { >> - struct command *c; >> - >> - while ((c = g_queue_pop_head(attrib->requests))) { >> - if (c->func) >> - c->func(ATT_ECODE_IO, NULL, 0, c->user_data); >> - command_destroy(c); >> - } >> - >> - attrib->read_watch = 0; >> - >> - return FALSE; >> - } >> - >> - memset(buf, 0, sizeof(buf)); >> - >> - iostat = g_io_channel_read_chars(io, (char *) buf, sizeof(buf), >> - &len, NULL); >> - if (iostat != G_IO_STATUS_NORMAL) { >> - status = ATT_ECODE_IO; >> - goto done; >> - } >> - >> - for (l = attrib->events; l; l = l->next) { >> - struct event *evt = l->data; >> - >> - if (match_event(evt, buf, len)) >> - evt->func(buf, len, evt->user_data); >> - } >> - >> - if (!is_response(buf[0])) >> - return TRUE; >> - >> - if (attrib->timeout_watch > 0) { >> - g_source_remove(attrib->timeout_watch); >> - attrib->timeout_watch = 0; >> - } >> - >> - cmd = g_queue_pop_head(attrib->requests); >> - if (cmd == NULL) { >> - /* Keep the watch if we have events to report */ >> - return attrib->events != NULL; >> - } >> - >> - if (buf[0] == ATT_OP_ERROR) { >> - status = buf[4]; >> - goto done; >> - } >> - >> - if (cmd->expected != buf[0]) { >> - status = ATT_ECODE_IO; >> - goto done; >> - } >> - >> - status = 0; >> - >> -done: >> - if (!g_queue_is_empty(attrib->requests) || >> - !g_queue_is_empty(attrib->responses)) >> - wake_up_sender(attrib); >> - >> - if (cmd) { >> - if (cmd->func) >> - cmd->func(status, buf, len, cmd->user_data); >> - >> - command_destroy(cmd); >> - } >> + uint8_t *buf; >> + struct attrib_callbacks *cb = user_data; >> >> - return TRUE; >> -} >> + if (!cb) >> + return; >> >> -GAttrib *g_attrib_new(GIOChannel *io, guint16 mtu) >> -{ >> - struct _GAttrib *attrib; >> + if (cb->notify_func == NULL) > > Use ! for pointer checking.
