Re: Making rsync compile under Mac OS X 10.3.9 with extended attributes

[Vitorio Machado]

Well, it seems that we just use definitions from the system acl.h

I'm still studying the code to see if it needs other changes.

So putting the acl.h attached into /Developer/SDKs/MacOSX10.3.9.sdk/ usr/include/sys/ should correct first errors.

acl.h

This is a bit out of my league. I've done some applescript applications including backuplist+ which rsync 3 has improved a great deal. I was hoping to make it backwards compatible to 10.3X so it would be great if we can do something to improve the xattrs and or ACL's. If you saw my other post, I also found that OSX creation dates aren't saved either with the build I did on 10.3 even with the patch for that.... I have little experience with OBJ-C (though I use lots of "call method") or C etc.... so you would have to see if you can figure that out. Keep me informed. Anything I can do though , let me know. Thanks, Rob

Sorry, I've misread your mail.















Chin up, we can do it!

But don't give up, I think that if we correct the headers in 10.3, we have a chance to make it compile. We should look at the ACL and xattr code and see if there are only constant and variable definition on the system headers that are not found in 10.3 or if it's more deep lied to the 10.4 API. In this case it represents much more work, but we have the chance that the basic system layer (Darwin) of 10.4 is released open source... So maybe we could take some code from there to have our xattr on 10.3... So, if nobody have a better idea, I think we should proceed like this: 1) Look on ACL and xattr code to understand what code they expect from the system 2a) If it's just a definition stuff (variable declaration, constants, etc) we can try a workaround of the configure script or something to put another header for 10.3 systems giving all those stuff that aren't built-in in the system headers. This shouldn't represent a lot of work 2b) If xattr and ACL code expect to use system fonctions, it won't be so simple... We can try patching the 10.3 system with some code of Darwin 8 (system code of 10.4 OS) hoping not have to go too deep, but just getting 1 or 2 files from it. 3) compile rsync with xattr support successfully with our little hacking. I will start looking into the code to try to figure out xattr and acl dependencies on the system. But I don't have Mac OS 10.3 here, only 10.4. It will be impossible for me to make any test today.

Hi Vitorio,

Well, actually, it only compiles only with --disable-acl-support --disable-xattr-support. which kind of defeats the whole purpose since xattrs are out of the picture.

Interesting,

So patched rsync compiles with --disable-acl-support --enable- xattr-support. Can you give an output of rsync --version to see if it says that xattr is enabled on capabilities?

Hi Matt,

I tried

./configure --disable-acl-support --enable-xattr-support

and got

`XATTR_NOFOLLOW' undeclared (first use in this function)

so then

/configure --disable-acl-support --disable-xattr-support

which worked

then added patches

patch -p1 <patches/flags.diff
patch -p1 <patches/osx-create-time.diff
./configure --disable-acl-support --enable-xattr-support
make

OK this time. Then I tried some simple tests on OS10.3X

mypathto/rsync -a --fileflags testdir destdir  (no AX of course!)





Thanks Rob

It works and flags seem to work at least for locked files. Creation time was not saved though..... any thoughts on xattrs or creation dates? Quite a few people still ask me to make support scripts on OS 10.3.9. Acls probably not such an issue on OS 10.3 and earlier.
