RE: svn corrupts binary files on import

Thanks to those that responded so quickly to my question.

I am concerned that the default setup is to mangle EOL characters.

I compiled svn from subversion-1.2.3-1.tar.gz using an RPM spec file
based on the one from David Summers. I used the cvs2svn utility to
construct the initial repository. That is it. The rest is a default SVN
setup, I did not add any "auto-props" that I know of.

Here is my ~/.subversion/config (relevant section):

[auto-props]
### The format of the entries is:
### file-name-pattern = propname[=value][;propname[=value]...]
### The file-name-pattern can contain wildcards (such as '*' and
### '?'). All entries which match will be applied to the file.
### Note that auto-props functionality must be enabled, which
### is typically done by setting the 'enable-auto-props' option.
# *.c = svn:eol-style=native
# *.cpp = svn:eol-style=native
# *.h = svn:eol-style=native
# *.dsp = svn:eol-style=CRLF
# *.dsw = svn:eol-style=CRLF
# *.sh = svn:eol-style=native;svn:executable
# *.txt = svn:eol-style=native
# *.png = svn:mime-type=image/png
# *.jpg = svn:mime-type=image/jpeg
# Makefile = svn:eol-style=native

I have no /etc/subversion, and I could not find anything relevant on the
server side. I would expect svn to leave my binaries alone by default,
but that is not the behavior I got. I have attached the spec file in
case there is something in there that did it which I do not understand.

How can I setup an auto-prop that turns off all mangling for binary
files? (Anything that svn puts (bin) next to on import). I will make
this the default so no one gets surprised.

I see in the manual 'svn:eol-style' property, but I don't see a setting
for "don't touch file".

Thank you for your help,
Federico

So you've got auto-props enabled in your client's config file, and
you've told Subversion to mangle line endings on all files. And
Subversion is doing so.

Don't Do That. :-) Instead, tell Subversion to mangle line endings
only on the file types whose line endings you actually want it to
mangle.
