[Back to not solved] Block notify refusing to execute script

As you can see, I've tried lots of configurations. Here's me running the command myself:-

Code:

[bitcoin@steam .bitcoin]$ /home/bitcoin/block.sh "000000000000000374a7b6359cc993d3638c72c14d8c7529fef7e6e7e545bffb"
[bitcoin@steam .bitcoin]$

As you can see, works fine:-

Code:

[bitcoin@steam ~]$ cat block.log
000000000000000374a7b6359cc993d3638c72c14d8c7529fef7e6e7e545bffb

The block.sh:-

Code:

[bitcoin@steam ~]$ cat block.sh
echo "$@" >> /home/bitcoin/block.log

Any help? I can't work out why it refuses to run.

EDIT:- Nor this:-

Code:

2013-12-25 22:53:32 runCommand error: system("/usr/bin/bash" "/home/bitcoin/block.sh" "00000000000000025efa4d291485de8c34136c3d0d6b2cfd487514b4f81c27c5") returned -1

Your block.sh isn't a valid executable. It needs to start with a #! line or be executed by a shell explicitly.

I tried specifically calling it via bash, didn't work. Added a hashbang to the start of the shell script, see if that works.

Code:

4 -rwx------ 1 bitcoin bitcoin 38 Dec 25 20:14 wallet.sh

I even went through with the time to compile a c++ app that simply called (As, from the log, this seems to be the function bitcoind calls):-

Code:

system("/home/bitcoin/block.sh thisisarandomhash");

And it worked fine, I also tried copying block.sh to /tmp/block.sh, and, giving it 777 perms:-

Code:

[bitcoin@steam .bitcoin]$ tail -f debug.log | grep block.sh

SE?
Any other errors popping up in /var/log/* ?
What is your walletnotify= line in your .conf?

I've tried a hell of a lot of wallet notifies so far, including, but not limited to:-

Code:

blocknotify=/tmp/block.sh

Code:

blocknotify="/tmp/block.sh"

Code:

blocknotify=/home/bitcoin/block.sh "%s"

Code:

blocknotify="/home/bitcoin/block.sh" "%s"

Code:

blocknotify="/home/bitcoin/block.sh" %s

Code:

blocknotify=/home/bitcoin/block.sh %s

Code:

blocknotify="/bin/bash" "/home/bitcoin/block.sh" "%s"

Code:

blocknotify="/bin/sh" "/home/bitcoin/block.sh" "%s"

Running:-

Code:

journalctl -f

and initiating bitcoind again resulted in nothing new being dumped to journalctl.

Well, I worked it out. Apparently there was an error else-where in my config that was fucking everything up. Woohoo, non-useful error messages are non-useful.

Code:

[bitcoin@steam ~]$ tail -f block.log

For later reference, if someone is googling this, the issue was that "wallet" and "alert" notify were _APPARENTLY_ formatted incorrectly (despite looking okay when viewing 'em), once deleting those two entries everything works.

This issue has popped back up, not changed anything. Great.

If you are specifying these parameters in the config file, don't use quotes, and do use an absolute path. Now that you've fixed the other issue!

Do not use an absolute path? Then, what's the current directory I'm in? The directory I run bitcoind from? $HOME/.bitcoin?

I have issues even if I just do:-

Code:

blocknotify=echo %s

Which, isn't absolute, nor does it contain quotes, so, same issue.

Whoops, well, I've also tried (Which was working till it randomly stopped, includes hashbang to /bin/sh):-

Code:

/home/bitcoin/block.sh %s

I'm unsure how how to use an absolute path of sh or something of the like without quotes, as, the space for the argument would break it:-

Code:

/bin/sh -c /home/bitcoin/block.sh<SpaceHereWouldBreakArgumentsBeingParsedToTheBashScript>%s

I'd need:-

Code:

/bin/sh -c "/home/bitcoin/block.sh %s"

EDIT:- This was the .conf that worked just fine, until, well, it randomly stopped working without me updating anything (System, .conf, bitcoin, .sh, anything!):-

Code:

rpcuser=no.
rpcpassword=no.
maxconnections=1000
checklevel=4
keypool=10000
rpcallowip=127.0.0.1
server=1
blocknotify=/home/bitcoin/block.sh %s
walletnotify=/home/bitcoin/wallet.sh %s
alertnotify=/home/bitcoin/alert.sh %s

I did, but, I had absolutely nothing to do with it, one day it just started working. Sorry.

[nicon]

Ok, wow...

So do you specify this in the conf file

Code:

blocknotify=/home/bitcoin/block.sh %s

and in the block.sh file:

Code:

#!/bin/sh
code goes here

not sure if I should use dh or bash and if I should call the .sh file direct or via blocknotify=/bin/sh /home/bitcoin/block.sh %s

How are you doing this?
