kandi X-RAY | introspectable Summary
Reflections, an access to program elements structure from themselves, although not recommended in applications are essential when creating frameworks. Java has somewhat complicated and verbose ways to do reflections, sometimes to the extremes. Introspectable comes to rescue. This library has few methods that eases common reflection tasks.

QUESTION
I am using Raspberry Pi as a BLE Peripheral and nRF Connect tool as BLE Client. In Raspberry Pi, I'm running Simple Agent Test Program, Advertisement Program and Gatt Server Program given in the Bluez Test Folder.
From the nRF Connect Tool, I, first bonded the devices and connected the devices. I have attached the dbus logs for the process.
- While bonding, the log shows the following
signal time=1595076323.849939 sender=:1.15 -> destination=(null destination) serial=863 path=/org/bluez/hci0/dev_04_C8_07_BC_23_7A; interface=org.freedesktop.DBus.Properties; member=PropertiesChanged
ANSWER
Answered 2020-Jul-19 at 05:40So, after many hours of trial and error, I have been able to reproduce the failure case and successful case consistently.
Failure Case:
- Boot up the Pi.
- Start the agent, advertisement and gatt server.
- Bond the device. Connect it.
- Try to read the encrypted characteristic. It fails.
Success Case:
- Boot up the Pi.
- Restart bluetooth service.
- Start the agent, advertisement and gatt server.
- Bond the device. Connect it.
- Try to read the encrypted characteristic. It succeeds.
So, for the time being, the workaround seems to be restarting the bluetooth service after boot up before starting the agents and advertisements.
Fixing the root cause: The solution to this problem is given in this Github link.
After much digging, I noticed that this problem is caused by the state the bluetooth chip is in at the time BlueZ is fired up (you can check the state with hciconfig hci0). If it's in "UP RUNNING" state or in "UP RUNNING PSCAN ISCAN" state, BlueZ complains with one or more of these:
Failed to set mode: Rejected (0x0b) Failed to set mode: Rejected (0x0b) Failed to set privacy: Rejected (0x0b)
But if it's in "DOWN" state, BlueZ starts with no issues. So, you first have to do hciconfig hci0 down before the bluetooth service starts up. But before you can use hciconfig, you also need to ensure the sys-subsystem-bluetooth-devices-hci0.device service has started!
Solution 1:
I ended up disabling the automatic boot sequence, and run this script instead:

As the documentation explains:
[...] This is accomplished by attaching a one or more classes derived from QDBusAbstractAdaptor to a normal QObject and then registering that QObject with registerObject().
Change the registerObject argument to the parent, and it will work:
QUESTION
I'm trying to solve a problem with my git history.
I have two branches, lets call them a and b, a is the source branch for my repository, and b was branched off it. Many merged pull requests (a mix of merge commits, and squashed commits) happen to a, and b is not rebased, neither are these PRs re-opened against b. In order to update b, I (naively) resort to cherry-picking the merge commits from a that are applicable to b.
Over time as the code is tested and approved in a, b is now equal to a, with an empty diff, but the history shows, (as expected) a divergence in commits. (b is seen as many commits ahead of a in Github).
I would like to eliminate this divergence, if I perform merge commits from either one into the other, I get a long string of commits with no changes (except in some cases on Github where it gets confused), which would pollute the history of either branch if allowed onto them.
e.g. git merge a from b or git merge b from a shows a long string of commits in the log. (Edit: this is with --no-ff).
If I perform a squash, I get a nice message listing those commits with no changes.
e.g. git merge a --squash from b or git merge b --squash from a requires git commit --allow-empty.
But that does not prevent the "this branch is ahead/behind" situation.
So my question is how do I produce a single commit (can be in either or both branches) to prevent the "ahead/behind" situation.
Edit: This is mainly for ease of tracing whats happened on Github, I know how git works and know how to do this by destroying the history of one or the other branches by force pushing, but I'm trying to preserve both in a way that is easily introspectable.
...ANSWER
Answered 2020-Feb-19 at 22:08The only real answer here is that you don't.
What Git has—what it stores—is a graph of commits. Each commit has its own unique hash ID, never to be used by any other commit in this or any other repository.1 Each commit also points (backwards) to its parent commit(s); this is what forms the graph.
That is, given a linear chain of commits, using uppercase letters to stand in for their actual big ugly hash IDs, we can draw them like this:

I asked this in a comment of a previous question but I think it is better to move it here as a new independent question.
I am trying to figure out how to translate this Python code to emit a dbus signal into Lua using lgi DBus:
...ANSWER
Answered 2019-Mar-11 at 17:02Heh, Google just lead me here while looking at https://github.com/pavouk/lgi/issues/220.
Somehow I feel like your code example cannot work as-is / is not some self-contained python code. Hence, I will go with the comment in the text:
Emit / Publish a signal that is a random integer every second
Lua code doing this (well, except for "random integer", unless you consider 42 to be random):
QUESTION
I am able to introspect a DBus node, and get some XML which includes information about the child nodes. However, this requires me to parse XML, and I'm trying to keep the application lightweight. What gdbus function can I use to simply get a list of child node object names?
Here is the code that fetches the XML.
...ANSWER
Answered 2019-Jan-09 at 21:39I think your best bet is to use the built-in XML parser. It's how the gdbus introspect command line tool is implemented.
Call the g_dbus_node_info_new_for_xml function to parse the XML. This give you back a GDBusNodeInfo, which you must free with g_dbus_node_info_unref(). The best example I can find of how to use it is here, which parses the XML, then loops through the nodes element of the struct that's returned.

QUESTION
I'm new to the accessibility stuff on Android. While going through the classes and documentation I came across TYPE_ACCESSIBILITY_OVERLAY inside the WindowManager class.
The documentation says (only the relevant text)
For example, if there is a full screen accessibility overlay that is touchable, the windows below it will be introspectable by an accessibility service even though they are covered by a touchable window.
So I set out to achieve just that, a full screen accessibility overlay and try to introspect the windows below it
Extended AccessibilityService and added my full screen overlay when onServiceConnected is called (the inspiration for adding overlay came from here)
ANSWER
Answered 2018-Jun-14 at 15:04What you seem to be missing is flagRetrieveInteractiveWindows on your configuration. These properties and window layout paremeters configuration should work, without requiring for you to disable canRequestTouchExplorationMode in order to get the events and having getWindows return the AccessibilityWindowInfo instances underneath yours:
QUESTION
I can't seem to access certain (most) of the properties of the BlueZ MediaPlayer1 interface using Python:
...ANSWER
Answered 2017-Dec-10 at 05:53Bluez only shows up application settings supported by the target in DBus Properties. In other words, properties that you see on DBus introspection are possible settings and properties that GetAll method returns are supported settings of the target device. Bluez which plays the controller role of AVRCP Bluetooth profile sends "List Player Application Settings (11)" command to the target device after connection establishment; Response to this command tells all the application settings that are supported by the target. So, controller (i.e., Raspberry Pi in your case) can only alter these settings on the target. See code in profile/avtcp.c in the bluez source for better understanding.
To validate, you can connect any other know AVRCP profile supported headset which has an option to change settings like "repeat" and see whether it works with your phone or not.
