Greetings,
Using NAnt to automate several Subversion tasks on
our repositories, I've run into an issue with <exec>
calling Subversion's svnadmin dump. I don't believe
it's a problem with svnadmin per se.
Here is the culprit:
<exec program="${svnadmin}"
failonerror="false"
output="${svnadmin-dump.output}"
resultproperty="svnadmin-dump.result">
<arg value="dump"/>
<arg value="${repos}"/>
</exec>
This does generate the dump file, however I have
to run Nant with -quiet (otherwise ALL the output
is shown!) and when I try to load the repository,
svnadmin complains:
"svn: Malformed dumpfile header"
Calling svnadmin dump from the commandline against
the same repository, and comparing this against the
dump file generated from NAnt, the NAnt dump is ~60%
bigger, missing some information at the top, and the
binary data is all out of whack. NAnt also takes at
least 5 times longer to generate the dump file.
I've hacked a workaround for it, by creating a dos
batch file (dump.bat) which itself calls svnadmin:
call %1 %2 %3 > %4
And then changing the <exec> call in NAnt to:
<exec program="dump.bat"
failonerror="false"
resultproperty="svnadmin-dump.result">
<arg value="${svnadmin}"/>
<arg value="dump"/>
<arg value="${repos}"/>
<arg value="${svnadmin-dump.output}"/>
</exec>
But this does seem like a bit of a kludge, something
weird (at least to me) is happening in NAnt, or in
way I'm using <exec>.
Run from latest CVS build of NAnt (Build 0.85.1859.0)
with the latest (stable) release of SVN (1.1.3)
peace,
si
