mpbb was improved in January 2021 so that separate builds would be scheduled 
for any dependencies that had not yet been built:

https://github.com/macports/mpbb/commit/bb4a1f6089ee09fc20d00d3556311c3b0e7d2d99

Prior to that time, we would only schedule separate builds for the 
ports/subports that were modified in the commit (or were specified in the force 
build list) that had not already been built. Any unbuilt dependencies would be 
built coincidentally in the "install dependencies" step and uploaded in the 
"gather archives" step.

Do you have any clue or any alternative explanation why llvm-9.0 would
be missing on this list?
https://build.macports.org/builders/ports-10.6_x86_64-watcher/builds/9920

The port must have been built some time between 9907 and 9920:
https://build.macports.org/builders/ports-10.6_x86_64-watcher/builds/9907

The port grepcidr was built in
https://build.macports.org/builders/ports-10.6_x86_64-watcher/builds/9918
and the timestamp of the binary from 10.6_x86_64 is 2020-09-07 07:55

The timestamp of llvm-9.0 is 2020-09-07 07:56.

python38 was probably the first port built in portwatcher 9920.
Its timestamp is 2020-09-07 08:14.

Ports from 9919 are probably not distributable, so we don't have any
timestamps there.

I'm not aware of a bug in that script.

Don't do that.

That was just an example of one improvement that could be made. It's 
been discussed before on the mailing list that it would be nice if the 
status indicators also took into account whether binaries are available 
(and other information like known_fail).

To me it looks like it was broken for a very short period of time on
all systems from 10.6 to 10.9 (tons of ports were broken).
https://build.macports.org/builders/ports-10.6_x86_64-watcher/builds/9907

It must have been fixed some 30 hours later judging from the
timestamps. I see that Ryan scheduled a rebuild of many failed jobs in
https://build.macports.org/builders/ports-10.6_x86_64-watcher/builds/9920
including llvm-9.0, but llvm-9.0 is missing on that list of subports.

I suspect that's because llvm-9.0 must have been the default compiler
for one of the ports built somewhere inbetween those two portwatcher
jobs (logs for portbuilder are gone already, so we cannot investigate
those any longer), and it was built and uploaded successfully as part
of building another unrelated ports, but we most likely don't account
for a broken compiler (as a port dependency) being built explicitly in
a standalone portbuilder job.

(There are only 12 portwatcher jobs to investigate if we wanted to
find which port was that ;)

That probably counts as a bug in the Tcl script that returns the list
of subports to be built.

The fastest one would be by revbumping that port ;)

The whole logic for showing the port as green currently requires
having an entry of a successful port build in a database. But
apparently we never had such a build, and you cannot force build a
port that already exists on the package server either.

Sure, there's also a problem that Joshua pointed out that needs
addressing, but even that fix wouldn't solve this particular instance.

Mojca

(My feature request for the webapp would be to allow an explicit URL
to show older builds of a port. But it makes sense to deploy the new
site first.)

The status indicator isn't very sophisticated, it simply shows the 
success or failure of the last build it knows about for the port on that 
platform. If you click on the Build Information tab, you can see that 
indeed the last known build on 10.6 failed (due to dependencies 
failing). For whatever reason, the later build that obviously succeeded 
is not in the database.


There are a number of improvements to the display that have been 
suggested, e.g. 
, and I think 
some of them are implemented in the updated version of the web app 
which, last I heard, Arjun and Mojca are working to deploy.
