From what is seen, it does indeed looks like amazon ses is sending emails with different message ids to each participant in the mailing list. Mailgun, on the other hand, was keeping the original message id in the email. > But at the same time, it's not impossible to switch back to mailgun, > if threading is partially disrupted, and we can't find a solution. Now that the source of the problem has been identified, i hope a solution can be found. Like Phil noted, mailgun is indeed very expensive. Best regards, Julien

Usually it's not the mailing list itself at fault, but due to the mail client used by the person posting -- or sometimes that they're replying to a digest rather than the original mail, so the context headers are lost (even if they edit it to look like it was a reply to a single post). I have noticed an apparent increase recently in the number of posts that appear "flat" or semi-flat (still showing as a reply, but to a grandparent post rather than the real parent post) -- but other recent threads still do appear normally nested, so I don't think it's a systemic issue. This is what I'm seeing -- note that the current thread appears semi-flat (even though most of these sibling messages were actually a reply chain), but the "replacing the ML with a forum" thread appears mostly normal. https://imgur.com/a/GfTS6ig

Amazon SES is a basic SMTP gateway service. It has fewer features and options than mailgun. Incoming and outgoing mail are handled differently. When emails are sent out from the mailman server, they are proxied through SES. Only verified identities may send mail. Notice the sender says "boost(a)lists.boost.org", since lists.boost.org is a verified domain that is working, otherwise it would be blocked. Incoming emails go directly to mailman, not through any intermediary. SES is not involved with incoming emails to the mail server. This is the same situation as before. - Are emails being sent out? Almost certainly all the emails are being sent as shown by the mail logs on the mail server, and on SES it says "0.01% bounce rate", which is very good. - Is threading working? checking lists.boost.org, messages are organized into threads. However, it may be that threading is only partially correct. If that is what you are reporting. There are only a few settings exposed in the gateway to be able to adjust. One of them which hasn't been added yet is "Custom MAIL FROM domain", that could be modified from the default of amazonses.com to "a subdomain of lists.boost.org". As an experiment, I will set that today, and observe if it helps. Mailgun has been in production for many years. It costs $500 per month to send smtp messages. It's a reasonable idea to try out another service that's only 5% of the cost. But at the same time, it's not impossible to switch back to mailgun, if threading is partially disrupted, and we can't find a solution.

Re: [boost] Boost CI Infrastructure

Vinnie Falco via Boost <boost(a)lists.boost.org> writes: > I guess what I'm trying to say here is that we care deeply about long > turnaround times on CI ("they suck) have been working on the problem. This email may give an impression that the CI suckage is an inherent problem that one just has to live with so I want to provide a different perspective. As part of the build2 project we have implemented our own CI infrastructure from the grounds up: from managing our own hardware, to VM-based CI job handling, to custom web interface for result viewing. This was based on concluding that all the existing off- the-shelf solutions are primarily focused on "web development" and will result in the subpar experience for large C/C++ projects (Boost, Qt, etc). Some key differences of our approach compared to the commonly used setups (e.g., GitHub Actions): 1. "Push CI" explicitly triggered during development as opposed to "pull CI" triggered on commit/PR/etc. This allows specifying the target configurations to build in, alternative project configurations, etc.[1] 2. Standard "CI script"[2] that is used by all the C/C++ projects instead of each projects doing their own thing. This "CI script" is written in C++ and has evolved to cover a fairly elaborate set of scenarios, including: 1. Testing of preparation of source distributions (to make sure there are no missing files, etc). 2. Testing of libraries as installed (to make sure no public headers were omitted during installation, etc). 3. Ability to test projects with build-time dependencies (e.g., source code generators, build system modules, etc) in cross- compiled environments. 3. Interactive CI support. The push CI can request an interactive session where the above "CI script" is stopped at one of the pre-defined breakpoints allowing the user to login into the machine via VNC or SSH and investigate the problem. 4. Large number of build configurations covering all the major platforms/compilers/versions[3] with a well-defined obsolescence policy. To give a sense of how this works in practice, here is my typical workflow: 1. Hack on some feature in a branch, build and test locally. 2. When need to test on other platforms, push the branch to remote and submit the CI request. Normally it's just: $ bdep ci The result is a URL with the interface like this: https://ci.stage.build2.org/@04e5ffb7-cf96-42f9-bc91-94d3ffe48de1 One nice touch is that it detects compiler warnings, as can be seen in this result: https://ci.stage.build2.org/@23da340d-cb4d-4105-8474-bb870e1a1380 (Drop the UUID from the above URL to see some other CI jobs.) 3. Say everything works fine except on Windows with an old MSVC version. If the fix is clear, I push it and re-CI but just on this specific configuration (this is both faster for me and saves resources for others): $ bdep ci --build-config windows_10-msvc_14.3 If the fix is not clear and I need to play with it or run the debugger, I can request an interactive CI session: $ bdep ci --interactive windows_10-msvc_14.3/error That `/error` part is a breakpoint, meaning that the CI job will execute the standard "CI script" until the first error (compile error, test failure, etc) and pause. 4. Once all is good I clean up my feature branch (squash commits, etc), rebase on master, CI one more time for good measure, and merge to master. When I push my changes to master, there can be a hook that submits a "verification" CI job.

I can see the threaded view is indeed broken in the mailman archive, for example see here: https://lists.boost.org/Archives/boost/2023/04/index.php You can see the initial post is not grouped with the following thread. I should also mention that I was not totally correct when I said I don't use threaded view when I read Boost ML. On my mobile email app that I forgot about, I do use threaded view, and I did notice that some messages were not grouped with the rest of the discussion. It didn't occur to me until now whether those messages were the initial ones in the discussion, but it may have been so.

And the mailing list will remain as-is, forever. This sounds like a pretty neat solution. I like the mailing list to participate in the communication, but I don't like to browse the ML archive to dig up old conversations. I think that's going to be easier with the forum. Hans
