Unable to create Subversion repository with compiled binaries(version 1.10.2) on AiX 7.2 machine

问题

We have compiled subversion 1.10.2 on AiX machine using the compile command :-

./configure CFLAGS="-I/temp1110/subversion/zlib" --without-berkeley-db --with-apr=/temp1110/subversion/apr --with-apr-util=/temp1110/subversion/apr-util --with-lz4=internal --with-utf8proc=internal --disable-nls

Whereas, after generating the required files using "make" command. We are unable to create a repository. After passing the command ./svnadmin create /temp1110/home/Repo_test", we get the error:

svnadmin: E000009: Can't write '/temp1110/home/Repo_test/db/current' atomically svnadmin: E000009: Can't flush file '/temp1110/home/Repo_test/db' to disk: Bad file number

Any idea how to resolve this?

回答1:

Well, you cannot solve this, this is a bug in subversion.

Or rather an AIX-specific problem: fsync(2) called on a directory returns errno=EBADF which makes subverions/libsvn_subr/io.c:svn_io_flush_to_disk sad.

This can be fixed with the following patch:
