Hi,
An easier option for the inefficient, yet very useful, svnmerge
script/program is to avoid using a paraphrase for the ssh public key
which is registered at Gna!. The insecure paraphrase is not the
password and not really that necessary. Key swapping has already
occurred by registering the key and hence the password is not asked
for.
Regards,
Edward

I have just tried to use svnmerge for the firdst time today and found it
fairly hellish because it asks for you passphrase over and over again.
However, I found this nice hack using expec
#!/usr/bin/expect --
#
# Wrap the svnmerge script, so we're only prompted for our password once.
#
# Written by Tilghman Lesher <repotools-mergetool@xxxxxxxxxxxxxxxx>
#
eval [ concat spawn /usr/bin/svnmerge.real [ lrange $argv 0 end ] ]
expect {
"Passphrase for" {
puts "ghere"
stty -echo
expect_user -re "(.*)\n"
stty echo
send "$expect_out(1,string)\r"
}
}
expect_after eof exit
while (1) {
expect {
"Passphrase for" {
send "$expect_out(1,string)\r"
}
}
}
which I modified as follows
#!/usr/bin/expect --
#
# Wrap the svnmerge script, so we're only prompted for our password once.
#
# Written by Tilghman Lesher <repotools-mergetool@xxxxxxxxxxxxxxxx>
#
set home $env(HOME)
set svn_merge_path [file join $home bin/svnmerge.py]
eval [ concat spawn $svn_merge_path [ lrange $argv 0 end ] ]
expect {
"*assphrase for" {
stty -echo
expect_user -re "(.*)\n"
stty echo
send "$expect_out(1,string)\r"
}
}
expect_after eof exit
while (1) {
expect
expect {
"*assphrase for" {
send "$expect_out(1,string)\r"
}
}
}
so
1. it now expects the real svnmerge.py to be in $HOME/bin
2. it had a capital P for passphrase which doesn't match all svn versions
3. I haven't managed to suppress all the extra printings of Enter
passphrase for key ... yest but should be able to
4, it will crash if it doesn't see a Enter passphrase at all:
expect: spawn id exp4 not open
while executing
"expect_after eof exit"
(file "/usr/jessy/garyt/bin/svnmerge" line 20)
/
