Simultaneous rsyncs?

Hi,

What would happen if two people ran rsync on the same set of source 
files to the same destination machine?  Do we need some sort of 
queuing or interlock mechanism to prevent simultaneous rsyncs?

We have a script that uses rsync to distribute files from our AFS 
space here to the local disks of about twenty-five machines around 
the US and Europe.  There are about ten or fifteen people here who 
update the source directory and run the distribution script.

So, someone might update the source directory while someone else is 
already doing a distribution.  That's actually not so bad, since when 
the first person then does a distribution, things will again be in 
sync.

More problematical is when two or more distributions overlap.  What 
would happen in that case?

It takes about twenty or thirty minutes to distribute the files to 
all the machines on our list.  So, it's possible that the two rsyncs 
would be working on the same destination machine at the same time.

If we don't need some sort of queue or interlock, then do we need to 
run a third rsync after the overlapping pair have finished to make 
sure that everything's OK?

Thanks,

Marc

Re: battlefield 1942 help

Does anybody have any idea why people needing help with Electronic Arts 
games keep finding the rsync list?  I've seen five or six of these since 
I've been on the list, and it's *always* somebody with an EA game in 
particular...

Things that make you go "hmmmm."

install-strip issue

>From 2.6.2's Makefile:

install: all
	...
	${INSTALLCMD} ${STRIP} -m 755 rsync$(EXEEXT) ${DESTDIR}${bindir}
	...
install-strip:
	$(MAKE) STRIP='-s' install

This doesn't work (at least) on OpenBSD, because install(1) there
will use the value of the environment variable STRIP as the command
to run for stripping the executable.

Renaming the variable will take care of this.

I submitted a patch in Feb 2004 to add a --fixedcsum-seed option
(which only sets checksum_seed to 32761, the batch file value):

Re: battlefield 1942 help

Our email addresses are already there for anybody that subscribes to the 
list - and where would a bunch of clueless EA gameplayers *get* a link 
to the rsync list to try it?  And why always EA games in particular?

I know, I know, it's as utterly off-topic as requests for videogame 
support are to begin with.  But I can't help wondering how the heck 
those wires got crossed, and where. =)

Re: battlefield 1942 help

Heh... think people are googling, finding that, and "replying through 
the website" at somewhere that has a web form for posting to the list? 
Makes... sense... I guess.

Sigh.  I don't know how some people *survive*...

Anyone ever come up with a patch for the chroot fix against 2.5?
