Unable to import a read-only directory to a http: repository

[stephen white <st...@cs.adelaide.edu.au>]

Checking the existing issues shows a few of similar, but not the same,  
kind of problem... so here's another data point:

	-->	You are now talking on #svn-dev
	<spoob>	need to enter a bug report, but thought I'd check here first.
	<spoob>	we're creating 3500 subversion repositories for computer  
science, but have run into a very minor problem.
	<spoob>	it's not possible to import into subversion from a read-only  
directory (handout), because subversion insists on creating a temporary  
file in the read only area.
	<spoob>	eg:   svn import -m "initial import"  
/users/teaching/handout/test  
https://repos.cs.adelaide.edu.au/svn/student123
	<spoob>	will result in "unable to create tempfile.tmp"
	<spoob>	so, bug or not?
	<ringstrom>	which version of svn?
	<spoob>	1.1.1 and 1.1.3
	<ringstrom>	that sounds like a bug, but I can try it here on trunk  
just to be sure
	<ringstrom>	what is cwd, btw?
	<spoob>	ok, to invoke the bug, you should not have write access to the  
directory being imported
	<spoob>	cwd is the student home directory, which is not  
/users/teaching/handout
	<spoob>	so something like /users/students/a1234567
	<ringstrom>	ok, thanks. gimme a couple of minutes.
	<ringstrom>	thanks
	<ringstrom>	I can't reproduce the bug with trunk.
	<ringstrom>	let me check 1.1 too just to be sure I'm testing the same  
thing
	<ringstrom>	hmm, I can't reproduce it with 1.1.2 either
	<spoob>	Hm. OK, let me reproduce here.
	<spoob>	steve@hon15 handout $ ls -ld test_05_s1_assign1
	<spoob>	drwxr-sr-x  2 brad teaching 4096 Feb 14 16:34

	<spoob>	steve@hon15 handout $ touch a test_05_s1_assign1/
	<spoob>	touch: setting times of `test_05_s1_assign1/': Permission  
denied

	<spoob>	steve@hon15 steve $ svn import -m "initial"  
/users/teaching/handout/test_05_s1_assign1/  
https://repos.cs.adelaide.edu.au/svn/steve

	<spoob>	Adding          
/users/teaching/handout/test_05_s1_assign1/notes.txt
	<spoob>	svn: Can't open  
'/users/teaching/handout/test_05_s1_assign1/tempfile.tmp': Permission  
denied
	<spoob>	a factor that may be relevant is that /users/teaching is an  
NFS mount
	<ringstrom>	what if you run:
	<ringstrom>	mkdir i i/d ; chmod -R a-w i
	<ringstrom>	rm -rf repos ; svnadmin create repos
	<ringstrom>	svn import -m "" i file://`pwd`/repos
	<ringstrom>	?
	<ringstrom>	do it in a temp dir
	<ringstrom>	or any repos will be removed
	<ringstrom>	i.e. any dir or file named "repos" will be removed
	<spoob>	steve@hon15 tmp $ svn import -m "" i file://`pwd`/repos
	<spoob>	Adding         i/d
	<spoob>	Committed revision 1.
	*	ringstrom is obviously missing something
	<spoob>	relevant lines from an strace
	<spoob>	stat64("/users/teaching/handout/test_05_s1_assign1/notes.txt",  
{st_mode=S_IFREG|0644, st_size=102, ...}) = 0
	<spoob>	write(1, "Adding         /users/teaching/h"..., 68Adding        
   /users/teaching/handout/test_05_s1_assign1/notes.txt) = 68
	<spoob>	open("/users/teaching/handout/test_05_s1_assign1/ 
tempfile.tmp", O_RDWR|O_CREAT|O_EXCL, 0666) = -1 EACCES (Permission  
denied)
	<spoob>	stat64("/users/teaching/handout/test_05_s1_assign1/ 
tempfile.tmp", 0xbfffef3c) = -1 ENOENT (No such file or directory)
	<ringstrom>	it could be that it needs non-file:
	*	ringstrom tries again with http
	<spoob>	that sounds like a distinct possibility. if the repo is  
remote, it may need a local file and attempts to put it in the  
originating area.
	<ringstrom>	ok, got it
	<ringstrom>	trunk has the problem too
	<ringstrom>	please file an issue

Hope this helps.

Thanks,
     Steve.
