Collect Time Travel traces quickly and easily with new command line recorder! Install anywhere (Windows 10 or later), record child processes, monitor process launch, then open in WinDbg. aka.ms/ttd/download. More details: learn.microsoft.com/en-us/windows-…

@GabrielLandau Once injected the IPC protocol should not write into the target process, but yes, we are not able to inject into PPL processes.

Thanks for the response. That sample uses ShellExecute to launch TTD.exe (which may launch TTDInject.exe). Neither can open our PPL process to perform the DLL injection. On top of that, there's the DLL signing requirements which block the DLLs from loading into PPL. We could work around both of these by ELAM-signing the TTD binaries and running them as AM-PPL, but then there's the concern about potential compromises of the PPL security model if the TTD IPC protocol allows arbitrary writes (or similar) into the target process.

Do you wish Time Travel Debugging was faster and more lightweight? Our latest version lets you decide exactly what you want recorded! Select modules to record or use the API for full control. Get your recording just the way you like it. Crusts optional. aka.ms/ttd

@GabrielLandau This will let you start and stop recording on yourself, without requiring injection. The link didn't work so search for WinDbg-Samples in github and look under the TTD folder.

@GabrielLandau The PPL subsystem doesn't offer a way for us to get in and record (kind of understandable given what PPL is). If you are building the code you want to record, the Live Recording API might work: WinDbg-Samples/TTD/LiveRecorderApiSample at master · microsoft/WinDbg-Samples

Have you ever wanted to open a TTD trace and analyze it for yourself, at the speed of .Calls()/.Memory() in WinDbg? Your wish has been granted! We have released an experimental version of our Replay API for you to use. See aka.ms/ttdsdk for documentation and samples.

Everything I need to know about VI I learned from a meme (forgot to configure the git editor and paid the price)

New WinDbg just dropped in the Microsoft Store! Faster downloads for large PDB files and console debuggers are part of the package! Note the architecture is part of the exe name. aka.ms/windbg.

Hey there - if you use windbg I would love to know if you have one of these tools installed as well (if more than one, choose the one you use most frequently)

@LundukeJournal Under what authority are they able to delete forks? Is there something in the license?

Open Source People are Fighting to Kill Open Source Projects A large portion of the people in "Open Source" -- including Red Hat -- have been moving, rather dramatically, away from some of the core ideals of "Open Source".

@timmisiak AFAIK it is still maintained by MS internal community

Anyone know if the MEX debugger extension is still being maintained?

If you update WinDbg today (1.2504.15001.0), you might notice another icon in the View tab of the ribbon, one called "Parallel Stacks". While incredibly useful in its own right, this isn't just a parallel stacks view. It's the introduction of graph visualization for extensions!

@gregthelaw Just get rid of the public keyword, that will make it safe ;)

Latest on memory safety: "The new US administration has removed everything from the White House web site and fired most of the CISA people who worked on memory safety." tbf, memory safety is pretty woke. hubs.ly/Q038Yn1h0

The latest TTD release includes some pretty cool changes; you can now 'break on registers' (!tt br) & navigate to the next module boundary (!tt bm) and more! 🔥 learn.microsoft.com/en-us/windows-…

@0vercl0k Thanks for the shout out - I am behind on sending out an announcement. We also fixed that .Heap() error you were seeing :)

@JamesMcNellis People escape either way 😉

Our team morale events when my teammates plan them: Escape rooms, VR experiences, laser tag. Our team morale events when I plan them: Dinner and a pilgrimage to see the San Francisco Symphony.

@lefticus Was the USB key plugged in when you rebooted?

#TIL that simply booting into Linux from a USB drive is enough to trigger the "enter your bitlocker key" prompt for Windows! Fortunately I had literally just 1 hr before backed up the key.

@JamesMcNellis Three months later: I should start writing the slides. 😄

@JamesMcNellis Cool! I am going to a performance at Tosca next week. 😉

I’m back in Karlsruhe this evening for Tosca. I won’t miss the surtitles tonight; I’m pretty sure I could sing most of it myself from memory (thankfully for everyone I don’t think that will be necessary.)

@lefticus How long are episodes in compiles? :)

Actual interaction I had awhile back: Them: I'd watch C++ Weekly, but I usually don't have enough time Me: Each episode is 5-10 minutes... Them: Oh! I just assumed they were like 30 minutes! Me: ... @cppweekly" target="_blank" rel="nofollow noopener">youtube.com/@cppweekly

@JamesMcNellis If it's anything like Star Wars Episode 9 I would go to the dinner 😊

@KensyAtMS Off by 1<<2 error

I have a hard choice to make… Next week I have a reservation at a Michelin restaurant I’ve been looking forward to, but I’ve just now learned there’s a Beethoven concert that night that I could get tickets to. Decisions, decisions.
