Hi,

At commit 464a29d3d74e7d2f27042db6ab166bfdbe1f992e ('git branch --all

core-updates has this commit at this time), the following error occurs
when trying to build ant-bootstrap, which causes the 409 dependent
packages to fail, also:

It fails quite quickly, so you can easily get a copy failing locally if
you want to test it out.

bug#36685: ant-bootstrap fails on core-updates (409 dependents)

[Efraim Flashner]

Building with gcc-5 didn't make it suddenly start working, before anyone
goes down that path.

This error means that it couldn’t find the version.txt file.  This is
strange because it’s right there in src/main, but not in build/classes.
So I thought I could just fix this by copying files from src/main to
build/classes and the bootstrap build does in fact begin:

It’s possible we could get away with just adding these lines:

  cp {src/main,build/classes}/org/apache/tools/ant/antlib.xml
  cp {src/main,build/classes}/org/apache/tools/ant/version.txt

However, this doesn’t seem to help.  Yes, the bootstrap script no longer
aborts but it gets stuck compiling things.  I can’t get it to tell me
anything about the compilation progress, but strace shows me that it
keeps stat’ing for non-existent files like "/tmp/files16bfb86414e_b"
until the end of the day.

Judging by the name of the file I think this is ant’s
src/main/org/apache/tools/ant/taskdefs/compilers/DefaultCompilerAdapter.java
that creates them, which is used by Jikes.java.  We should see if
there’s a race somewhere or if perhaps “jikes” crashes and thus gets
executed over and over again.

The problem appears to be in GNU Classpath (classpath-bootstrap).  Its
“native/jni/java-io/java_io_VMFile.c” defines
“Java_java_io_VMFile_exists”, which returns “1” when a file exists.  It
does so by calling “cpio_isFileExists” which is defined in
“native/jni/native-lib/cpio.c”:

--8<---------------cut here---------------start------------->8---
int cpio_isFileExists (const char *filename)
{
  struct stat statbuf;

  if (stat(filename, &statbuf) < 0)
    {
      return errno;
    }

  return 0;
}
--8<---------------cut here---------------end--------------->8---

I have confirmed with printf debugging that there’s a mismatch between
what the Java side thinks and what the C side tells it.  On the C side
the temporary file is determined to not exist yet, but on the Java side
it is said to exist — this is in spite of the fact that the Java side
only converts the C side’s return value.

Here’s an example from the printf output:

    exists? /tmp/files16bfd145b82_1 : 2 -- 0;
    classpath trying to create: /tmp/files16bfd145b82_1 exists? true

The first line is from C, the 2 is ENOENT, and 0 is the return value.
The zero is taken to be a Java boolean, so it maps to false.  The second
line comes from Java.

It hangs in “while (VMFile.exists(file.path))”:

--8<---------------cut here---------------start------------->8---
    File file;
    if (!VMFile.IS_DOS_8_3)
      {
        do
          {
            long now = System.currentTimeMillis();
            if (now > last_tmp)
              {
                // The last temporary file was created more than 1 ms ago.
                last_tmp = now;
                n_created = 0;
              }
            else
              n_created++;

            String name = Long.toHexString(now);
            if (n_created > 0)
              name += '_'+Integer.toHexString(n_created);
            String filename = prefix + name + suffix;
            file = new File(directory, filename);
          }
        while (VMFile.exists(file.path));
      }
    else …
--8<---------------cut here---------------end--------------->8---

I have confirmed that this is the problem by replacing “while
(VMFile.exists(file.path))” with “while (false)”.  The build doesn’t
fully complete then either, but it gets past the compilation of the Ant
source files.  This clears JamVM and Jikes.

I’m attaching my embarrassing printf debugging patches.

Any ideas?

It doesn’t.

VMFile.exists always returns “true”, no matter what.  The C part is
fine, but the Java part is not, so I suspected the JVM to be at fault.

I managed to build ant-bootstrap successfully with this patch:

Note that the change to native/jni/java-io/java_io_VMFile.c is necessary
even though it just prints things and compares values.  So this might be
time-related or it could be other stateful behaviour.  Don’t know yet.

The changes in ant-bootstrap might not be needed.

Can someone confirm that this patch helps?

I suspected some misguided optimizations, so I built jamvm-1-bootstrap

Any ideas?

currently on bayfront on core-updates ant-bootstrap builds just fine on
i686-linux, where it fails on master. Another option could be to
bootstrap 32 bit -> 64 bit

No, that’s wrong.

To my eternal embarrassement but also great relief this substitution has
the effect of commenting the *following* line which frees up previously
claimed resources (a bunch of characters making up the file name).  The
other comments I tested must have ended on \n, so they did not have this
effect.

Thanks to Julien for pointing this out!

So!  Creating a memory leak lets us successfully build ant-bootstrap.
It does not, however, get us all the way through the Java bootstrap.
When configuring the first icedtea I get this error:

Illegal instruction?  This uses JamVM 2.0.0 as the JVM.  I’ll try to
figure out what instruction this is and where it comes from.

I confirm this path works.
I tested a modified version, where I took out the comment text. It also
works that way.
We might contact the classpath devs to get a proper fix, and maybe a new
release, they
were super responsive the last time.

I confirm this path works.
I tested a modified version, where I took out the comment text. It also
works that way.
We might contact the classpath devs to get a proper fix, and maybe a new
release, they
were super responsive the last time.

Yes.  It’s just commenting the *following* line (i.e. removal of the
call to “free”) that fixes it.

I don’t think the problem is with GNU Classpath.  Classpath devs are
welcome to look at this, of course, but we are not even using the latest
version at this point in the bootstrap.

I wonder what could have caused this problem in the first place.  The
bootstrap hasn’t changed.  Using the same compiler as before doesn’t fix
it, so it’s probably not the compiler either.  So what is it?

Good.  We need to figure out why – is it miscompilation?  Tuning to a
different CPU type…?

The build aborts early with “ERROR: FreeType version 2.2.1 or higher is
required.”  So I added this:

  (substitute* "patches/freetypeversion.patch"
   (("REQUIRED_FREETYPE_VERSION = 2.2.1")
    "REQUIRED_FREETYPE_VERSION = 2.10.1"))

and icedtea is being built now.

We may want to check where the use of glibc-2.28 and gcc-5 is really
needed and where we can do without.

Can you check the content of config.log? It should tell you what test
it runs to determine whether attr is present or not.

It’s pretty straight-forward: xattr.h is no longer provided by the attr
package.  sys/xattr.h from glibc should be used instead, so I’ve patched
it.

I fixed another problem in the icedtea 2 build and moved on.  Let’s see
how far I’ll get this time.  In the meantime it would be great to reach
consensus on whether we should shrug off the patch that introduces a
memory leak in GNU Classpath 0.93 as part of the bootstrap or if we
should spend more time trying to figure out how we can avoid it.

[-- Attachment #1: Type: text/plain, Size: 257 bytes --]

So, with the following change I was able to build all the way up to the
latest openjdk.  Should we use it despite the introduction of a memory
leak in a bootstrap JVM?  Can we make the patch smaller (fewer uses of
glibc 2.28 or gcc-5)?

What do you think?

Re: bug#36685: ant-bootstrap fails on core-updates (409 dependents)

[Ricardo Wurmus]

[-- Attachment #1: Type: text/plain, Size: 257 bytes --]

So, with the following change I was able to build all the way up to the
latest openjdk.  Should we use it despite the introduction of a memory
leak in a bootstrap JVM?  Can we make the patch smaller (fewer uses of
glibc 2.28 or gcc-5)?

What do you think?

This would be possible, but I consider it a last resort and would very
much like to avoid having to cross-build things.

We should decide soon, because core-updates is about to be merged
