Lion buildbot disconnected while building textmate2 @2.0.9395

​https://build.macports.org/builders/buildports-lion-x86_64/builds/9347/steps/compile/logs/stdio says:

remoteFailed: [Failure instance: Traceback (failure with no frames): <class 'twisted.internet.error.ConnectionLost'>: Connection to the other side was lost in a non-clean fashion.

Subsequent commits are building on the other two buildbots but not on the Lion buildbot.

Fixed.

It happened again, at exactly the same place building the same port textmate2 @2.0.9395 (step "[155/157]"). Has the Lion buildbot experienced a kernel panic or what is the symptom?

I tried building textmate2 on my Lion machine with Xcode 4.3.3 and got:

Error: On Mac OS X 10.7, textmate2 2.0.9395 requires Xcode 4.4 or later but you have Xcode 4.3.3.
Error: See http://guide.macports.org/chunked/installing.xcode.html for download links.
Error: org.macports.extract for port textmate2 returned: incompatible Xcode version

This is because of this line in the portfile:

minimum_xcodeversions   {11 4.4}

This was added in r98375 to fix #36443 because textmate2 requires the 10.8 SDK even on 10.7.

If I remove the minimum_xcodeversions line, I get:

/usr/bin/clang is too old to build this project.

Please see README.md for build instructions.

I remember that awhile ago the Lion buildbot was using Xcode 4.3.3. It seems it has been updated since then (maybe when it was converted from a standalone server to a virtual machine?) but perhaps the command line tools were not updated and are thus still at the version of Xcode 4.3.3? Bill, what does running clang -v on the Lion buildbot say? What about xcodebuild -version?

The port should probably use the compiler_blacklist_versions portgroup to blacklist old clangs that are known not to work, so that any users who have updated Xcode but not its command line tools (which is quite a common occurrence) do not run into problems, or at least encounter a friendlier or earlier error message.

I will also test on a Mountain Lion Mac that still has Xcode 4.5.2 and its Apple clang version 4.1 (tags/Apple/clang-421.11.66) (based on LLVM 3.1svn) but it will take some time to build boost first.

Replying to ryandesign@…:

I filed #38422 for the way that this failed to build.

[wsiegrist@…]

It panicked. The slave had been running Xcode 4.5.2. I updated the slaves, including Xcode 4.6.1. Let's see if it still reproduces.

[wsiegrist@…]

It reproduced. I'm working on a fix.

[wsiegrist@…]

The slave has been patched to not panic. Now it fails like #38422.
