Ultimately, the common thing in all of these different version control systems 
is the patch file, the file that says what lines are being added and what lines 
are being taken away.

As long as you get the patch file cleanly to your target audience in some form, 
you’re done. That could be by email, posting to a mailing list, etc.

The idea of a pull request is when someone puts a user experience around 
handling the patch file. Github is probably the best example of this, thought 
the idea has been copied by everyone else. The Apache SVN repos are all 
mirrored at Github, meaning that you could use the Github pull request workflow 
to propose changes to SVN repos. Here is an example of a pull request made to 
the subversion project:

https://github.com/apache/subversion/pull/23

Example is perfect.

The "svnmucc put db.sql file:///var/lib/svn/db/db.sql” worked.

The “— -“ also worked, I think this is a quirk of apr-util:

https://apr.apache.org/docs/apr/1.7/group__apr__getopt.html#ga80d6ff2213da4e25406b3f179fa13989

Ideally the return message of APR_BADARG needs to be updated to hint that a “—“ 
might be needed.

From reading the manual it looks perfect, but I’m having no luck:

[root@seawitch postgres]# cat db.sql | svnmucc put - 
file:///var/lib/svn/db/db.sql
svnmucc: invalid option: 
Type 'svnmucc --help' for usage.

Alas the error message mentions an invalid option, but doesn’t say which 
option, or why it is invalid.

Is there a write opposite to "svn cat"?

[Graham Leggett via users]

Hi all,

The “svn cat” command will read a file from a (in my case local file based) 
repository to stdout. Is there an equivalent to write into a repository from 
the svn command line?

First prize from stdin, second prize from a local file on disk.

“svn import” comes close, but cannot be run twice, as the second time the 
command is run you get the following error:

svn: E150002: Path 'file:///var/lib/svn/postgres/database.sql' already exists

I know that it is possible to autocommit via WebDAV, but this is a local repo.

In our regulated world that is an important feature.

Once the repos get too big we start new ones. In the meantime, there is no such 
thing as “we did fraud^H^H^H^H^H a delete to make space”.

From experience it becomes too big when the underlying disk gets full. As long 
as your underlying disks can handle it, it works fine.

I use SVN for versioned incremental backups of files in the 0.5GB range. I’ve 
seen reports of others checking in multi GB files as backups with no trouble.

Best thing to do is to physically try it. Make a copy of your repo, then try 
check things into it, and see where your issues are.

Re: svn client - how do I force IPv6?

Alas this is the info for the JVM and does not work in this case. Most Java 
communication libraries ignore the JVM parameters for their own 
implementations. This is true of SVNKit, which reports that it relies 
completely on the configuration of the native svn client.

https://svnkit.com/documentation.html

"Native Subversion configuration files are used by default.”

That had already been done:

Is the IPv6 behaviour of the svn client (not the SVNKit client) documented 
anywhere? The svn book returns no hits for ipv6, the man page redirects you to 
svn help [subcommand], which doesn’t appear to mention common arguments.

SVNKit claims to be bug-for-bug compatible with native svn, but without any 
concrete definition of the native client behaviour the behaviour diverges.

svn client - how do I force IPv6?

[Graham Leggett via users]

Hi all,

What setting option under the ~/.subversion directory will force the use of 
IPv6 on outbound connections?

The backstory is that I have some SVNKit code that is stubbornly insisting on 
using IPv4 and failing. The SVNKit docs say it gets its config from the native 
~/.subversion directory, but I can find no mention of IPv6 and the native svn 
client config. I am specifically talking about an svn client accessing an IPv6 
server over https, I am not using svnserve.
