As the title says, I'm trying to ftpsync changed tree to our dev web server. On committing I get this error:
post-commit hook failed (exit code 13)
with output: Cannot create syncfile
for time sync option at
/data/ftpsync/ftpsync.pl line 484.
I've tried looking at line 484 but Perl looks like a foreign language to me :)
What permissions do I need to set and where so that syncfile can be created?
It creates the file in the current directory, and as far as I can tell doesn't change directories before that point. The easiest thing to do would be to change directories to /tmp before starting the script (and specify a local directory in its args instead of using the default .).

I like to execute a command line programm as a DAM workflow. I tried to implement the ImageMagic example from here: Best Practices for Configuring ImageMagick:
I addded a new Workflow Model,
added "command line" from the "DAM Workflow" list.
In the Argument tab set Mime type to "image/jpeg" (even tried wihtout Mime type)
and in Commands: "C:\Program Files\ImageMagick-7.0.7-Q16\magick.exe" convert ${file} -flip ${file}-flipped.jpg (instead of magick convet ... because in another discussion using an absolute path instead of global name helped people Re: CommmandLineProcess : ImageMagick)
I then added a luncher. And uploaded an Image to the DAM.
In the workflow > instances overview, i see that the workflow was started, it's running and the command line job is set to active.
Unfortunantly this state is never chnaged and no new asset is generated via imageMagic.
I even tried replacing the command with something simple like "ren C:\test\foo.txt bar.txt" which renames a local file. The chnage never happend either.
My question is what am i doing wrong, and how can i debug / find the command outputs? in \crx-quickstart\logs i couldn't find any logs regarding CommandLineProcess.
Thanx
I have a Powershell script that executes as a pre-build call for a Xamarin mobile app. The script changes the package name to match the build type e.g. Debug, Release.
To enable different "flavours" of the app to be created, I have written a batch file to replace the config file of the app with one matching the requested build type.
When I build from within Visual Studio, the powershell script runs as I expect and changes what I expected. However when the batch file runs I get an error message appearing:
Here is the content of the batch file, this was my first attempt at writing a batch file to build a code project:
#ECHO OFF
set buildVer=%1
set path=XamarinTestApp\XamarinTestApp
set msBuildDir=%WINDIR%\Microsoft.NET\Framework\v4.0.30319
echo %buildVer%
IF "%buildVer%"=="Release" (
goto :releaseBuild)
IF "%buildVer%"=="Test" (
goto :testBuild)
IF "%buildVer%"=="Dev" (
goto :devBuild)
:releaseBuild
set buildType=Release
copy /-y %path%\app.Release.config %path%\app.Config
goto :builder
:testBuild
set buildType=Release
copy /-y %path%\app.Test.config %path%\app.Config
goto :builder
:devBuild
set buildType=Debug
copy /-y %path%\app.Debug.config %path%\app.Config
goto :builder
:builder
call %msBuildDir%\msbuild.exe
C:\Projects\%path%\XamarinTestApp.Droid\XamarinTestApp.Droid.csproj /property:Configuration=%buildType% /target:SignAndroidPackage /verbosity:diag
I'm looking for any advice on either the error message I am getting, or some advice on how to get configurable information into my app.
Thanks.
Do not use path as user-variable. It is predefined by the system to locate executables.
Change that name to mypath - almost anything other than path.
from the prompt, use the command
set
to see a partial list of the names of variables that are set by the system
I'm using this article as a source to get me half way there, but I cannot figure out how to run supervisor with a custom config file path.
When I want to run supervisor manually, I just do:
supervisord -c /home/test/_app/supervisord.conf
When I implemented the auto start up script, it runs the default supervisor config file which is located in /etc/ directory. I don't want to use that one because it separates it from the core project folder and makes it hard to maintain and keep track of.
Try this:
In /etc/rc.d/init.d/supervisord, add prog_opts variable like this:
prog_opts=" -c /home/test/_app/supervisord.conf"
prog_bin="${exec_prefix}/bin/supervisord"
Then in start() function, change the call to:
daemon $prog_bin --pidfile $PIDFILE -- $prog_opts
I was able to fix this issue by simply deleting the default supervisord.conf file and then making a sym link with that default location and my custom conf file path.
Is there a way to specify the current working directory for the system command executed by the function module SXPG_COMMAND_EXECUTE?
I do not see any parameter which would allow me to do that either by defining the command in transaction SM69 or on the list of IMPORTING parameters in SE37.
It looks like by default such commands are started in DIR_HOME which can be viewed by the transaction AL11. Do I have any control over that?
There isn't a way of doing it via `SM69' unfortunately. I think the only solution is to create a script and call that.
I was going to suggest wrapping the statements in a SM69 command defined as a call to sh with parameters of -c 'cd <dir> && /path/to/command' but unfortunately that doesn't work. According to note 401095 wildcards are not permitted. When I tested, && was translated into a single &, causing the command to fail.
Would be good if you access this information using FM FILE_GET_NAME_USING_PATH (export the script name for which you want to find the physical directory).
The recieving path can be used in SXPG_COMMAND_EXECUTE.
Because the external commands I called were actually .bat files I solved this by putting the following expression at the beginning of each and every one.
cd /d %~dp0
This Stackoverflow question helped a lot actually.
I wrote a little CDN server that rebuilds its registry pool when new pool-content-packages are installed into that registry pool.
Instead of having each pool-content-package call the init.d of the cdn-server, I'd like to use triggers. That way it would restart the server only once at the end of an installation run, after all packages were installed.
What have I to do to use triggers in my packages with debhelper support?
What you are looking for is dpkg-triggers.
One solution with use of debhelper to build the debian packages is this:
Step 1)
Create file debian/<serverPackageName>.triggers (replace <serverPackageName> with name of your server package).
Step 1a)
Define a trigger that watch the directory of your pool. The content of file would be:
interest /path/to/my/pool
Step 1b)
But you can also define a named trigger, which have to be fired explicit (see step 3).
content of file:
interest cdn-pool-changed
The name of the trigger cdn-pool-changed is free. You can take what ever you want.
Step 2)
Add handler for trigger to file debian/<serverPackageName>.postinst (replace <serverPackageName> with name of your server package).
Example:
#!/bin/sh
set -e
case "$1" in
configure)
;;
triggered)
#here is the handler
/etc/init.d/<serverPackageName> restart
;;
abort-upgrade|abort-remove|abort-deconfigure)
;;
*)
echo "postinst called with unknown argument \`$1'" >&2
exit 1
;;
esac
#DEBHELPER#
exit 0
Replace <serverPackageName> with name of your server package.
Step 3) (only for named triggers, step 1b) )
Add in every content package the file debian/<contentPackageName>.triggers (replace <contentPackageName> with names of your content packages).
content of file:
activate cdn-pool-changed
Use same name for trigger you defined in step 1.
More detailed Information
The best description for dpkg-triggers I could found is "How to use dpkg triggers". The corresponding git repository with examples you can get here:
git clone git://anonscm.debian.org/users/seanius/dpkg-triggers-example.git
I had a need and read and re-read the docs many times. I think that the process is not clearly explain or rather what goes where is not clearly explained. Here I hope to clarify the use of Debian package triggers.
Service with Configuration Directory
A service reading its settings in a specific directory can mark that directory as being of interest.
Say I create a new service which reads settings from /usr/share/my-service/config/...
That service gets two additions:
In its debian directory I add my-service.triggers
And here are the contents:
# my-service.triggers
interest /usr/share/my-service/config
This means if any other package installs or removes a file from that directory, the trigger enters its "needs to be run" state.
In its debian directory I also add my-service.postinst
And I have a script as follow to check whether the trigger happened and run a process as required:
# my-service.postinst
if [ "$1" = "triggered" ]
then
if [ "$2" = "/usr/share/my-service/config" ]
then
# this may or may not be what you need to do, but this is often
# how you handle a change in your service config files
#
systemctl restart my-service
fi
exit 0
fi
That's it.
Now packages adding extensions to your service can add their own configuration file(s) under /usr/share/my-service/config (or a directory under /etc/my-service/my-service.d/... or /var/lib/my-service/..., although that last one should be reserved for dynamic files, not files installed from a package) and dpkg automatically calls your postinst script with:
postinst triggered /usr/share/my-service/config
# where /usr/share/my-service/config is your <interest-path>
This call happens only once and after all the packages were installed, hence the advantage of having a trigger in the first place. This way each package does not need to know that it has to restart my-service and it does not happen more than once, which could cause all sorts of side effects (i.e. the service tries to listen on a TCP port and get error: address already in use).
IMPORTANT: keep in mind that the postinst should include a line with #DEBHELPER#.
So you do not have to do anything special in other packages. Only make sure to install the configuration files in the correct directory and dpkg picks up from there (i.e. in my example under /usr/share/my-service/config).
I have an extension to BIND9 called ipmgr which makes use of .ini files saved in a specific folder. It uses the files to generate DNS zones (way less errors that way! and it includes support for getting letsencrypt certificates and settings for dmarc/dkim). This package uses this case: a simple directory where configuration files get installed. Other packages do not need to do anything other than install files in the right place (/usr/share/ipmgr/zones, for this package).
Service without a Configuration Folder
In some (rare?) cases, you may need to trigger something in a service which is not driven by the installation of a new configuration file.
In this case, you can use an arbitrary name (it should include your package name to make sure it is unique since this name is global to the entire Debian/Ubuntu system).
To make this one work, you need three files, one of which is a trigger in the other packages.
State the Interest
As above, we have an interest. In this case, the interest is stated as a name on its own. The dpkg system distinguish between a name and a path because a name cannot include a slash (/) character. Names are limited to ASCII except control characters and spaces. I would suggest you stick to a-z, 0-9 and dashes (-).
# my-service.triggers
interest my-service-settings
This is useful if you cannot simply track a folder. For example, the settings could come from a network connection that a package offers once installed.
Listen for the Triggers
Again, as above, you need a postinst script in your Service Package. This captures the trigger and allows you to run a command. The script is the same, only you test for the name instead of the folder (note that you can have any number of triggers, so you could also have both: a folder as above and a special name as here).
# my-service.postinst
if [ "$1" = "triggered" ]
then
if [ "$2" = "my-service-settings" ]
then
# this may or may not what you need to do, but this is often
# how you handle a change in your service config files
#
systemctl restart my-service
fi
exit 0
fi
The Trigger
As mentioned above, we need a third file. An arbitrary name is not going to be triggered automatically by dpkg. It wouldn't know whether your other package needs to trigger something just like that (although it is fairly automated as it is already).
So in other packages, you create a trigger file which looks like this:
# other-package.triggers
activate my-service-settings
Now we recognize the name, it is the same as the interest stated above.
In other words, if the trigger needs to run for something other than just the installation of files in a given location, use a special name and add this triggers file with the activate keyword.
Other Features
I have not tested the other features of the dpkg-trigger(1) tool. There are other keywords support in the triggers files:
interest
interest-await
interest-noawait
activate
activate-await
activate-noawait
The deb-triggers manual page has additional information about those. I am not too sure what the await/noawait implies other than the trigger may happen at any time when nowait is used.
Automatic Trigger Added
The build system on Ubuntu (probably Debian too) automatically adds a triggers file with the following when your package includes a library:
$ cat triggers
# Triggers added by dh_makeshlibs/11.1.6ubuntu2
activate-noawait ldconfig
I suggest you exercise caution if your package includes libraries. If you have your own triggers file, I do not know whether this addition will still happen automatically.
This also shows us a special case where it wants to use the noawait. If I understand correctly, it has to run the ldconfig trigger ASAP so your commands will work as expected after the unpack. Otherwise ldd will not know anything about your newly installed library.
