I have a parent folder and inside that I have a few folders. For an automation, I want to take the latest of the two folders according to timestamp.
I have tried to take the latest folder by using timstampselector.
<timestampselector property="latest.modified">
<path>
<dirset dir="MyDirectoryPath">
<include name="*" />
</dirset>
</path>
</timestampselector>
Inside my parent folder, I have the following folders:
test (Last modified on 07/04/2019 10:30 AM)
check (Last modified on 08/04/2019 05:00 PM)
integrate (Last modified on 08/04/2019 12:30 PM)
slave (Last modified on 09/04/2019 05:00 PM)
Our script should take the latest two modified folders, which is in the above case it should be integrate & slave.
How can I achieve that?
Generally speaking, it's a good idea to stay away from ant-contrib whenever possible. This particular problem can be quickly solved with native Ant's resource collections:
<last count="2" id="latest.two.files">
<sort>
<date />
<fileset dir="MyDirectoryPath" />
</sort>
</last>
Full example target:
<target name="select-latest">
<delete dir="testdir" />
<mkdir dir="testdir" />
<touch file="testdir/test" datetime="07/04/2019 10:30 AM" />
<touch file="testdir/check" datetime="08/04/2019 05:00 PM" />
<touch file="testdir/integrate" datetime="08/04/2019 12:30 PM" />
<touch file="testdir/slave" datetime="09/04/2019 05:00 PM" />
<last count="2" id="latest.two.files">
<sort>
<date />
<fileset dir="testdir" />
</sort>
</last>
<echo message="${toString:latest.two.files}" />
</target>
The task you are using is part of Ant-Contrib rather than core Ant. The documentation says you can use the count attribute to say how many items you want to select. In your case, set it to two:
<timestampselector property="latest.modified" count="2">
<path>
<dirset dir="MyDirectoryPath">
<include name="*" />
</dirset>
</path>
</timestampselector>
This appeared to work fine for me: the property was set to a comma-separated list of two directories.
I'm using Habitat Sitecore. It comes with a bunch of foundation and feature projects. One of the feature projects is Sitecore.Feature.ActiveDirectory.
I'm trying to configure domains from patch files. It is outlined by Kam in this blog.
In the /App_config/Include/Feature/Feature.ActiveDirectory.config, I added the following:
<?xml version="1.0" encoding="utf-8"?>
<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/" xmlns:set="http://www.sitecore.net/xmlconfig/set/">
<sitecore>
<switchingProviders>
<membership>
<provider providerName="ad" storeFullNames="false" wildcard="*" domains="ad" />
</membership>
<roleManager>
<provider providerName="ad" storeFullNames="false" wildcard="*" domains="ad" />
</roleManager>
</switchingProviders>
<domainManager>
<domains>
<domain id="ad" type="Sitecore.Security.Domains.Domain, Sitecore.Kernel" patch:after="domain[#id='default']">
<param desc="name">$(id)</param>
<ensureAnonymousUser>false</ensureAnonymousUser>
<locallyManaged>false</locallyManaged>
<isDefault>false</isDefault>
</domain>
</domains>
</domainManager>
</sitecore>
</configuration>
However, I get the following Exception:
A domain specified in the Sitecore.Security.SwitchingRoleProvider provider/domain map could not be found. Domain name: ad
in
<add name="switcher" type="Sitecore.Security.SwitchingRoleProvider, Sitecore.Kernel" applicationName="sitecore" mappings="switchingProviders/roleManager" />
What am I doing wrong?
Domains must be added directly to to Domains.config, located in App_Config\Security. It is not able to be patched. Make it part of your build train.
At runtime (when I call roslaunch), I want to create a new subdirectory in a known directory, and pass that path to two different nodes as a rosparam.
How can I edit my .launch file to do this?
For example,I have the folder ~/datacapture. whenever I use roslaunch, I want to create a subdirectory based on the current time, (ie ~/datacacpture/20161129_1352/) and pass that into a few nodes using rosparams.
To further explain what I want to do, here is an example roslaunch file:
<launch>
<node
name="node_A"
pkg="pkg_A"
type="A"
output="screen"
>
<param name="dataDumpFolder" value="???" />
</node>
<node
name="node_B"
pkg="pkg_B"
type="B"
output="screen"
>
<param name="dataDumpFolder" value="???" />
</node>
</launch>
What i want it to look like is this:
<launch>
#1) create a new folder using current date.
#2) pass it's filepath into a variable. let's call the variable, NEW_FOLDER_FILE_PATH
<node
name="node_A"
pkg="pkg_A"
type="A"
output="screen"
>
<param name="dataDumpFolder" value="NEW_FOLDER_FILE_PATH" />
</node>
<node
name="node_B"
pkg="pkg_B"
type="B"
output="screen"
>
<param name="dataDumpFolder" value="NEW_FOLDER_FILE_PATH" />
</node>
</launch>
This is not possible in any generic way. It's also not a good idea as (a) roslaunch was not meant for this and (b) the error handling will be interesting.
If there is any way to not require a shared folder name, or if you could pre-determine it and pass it on to the launch file as argument, or if you could have a node that provides the filename (as service or via latched topic), this may be preferable.
That said, the best option to do this within roslaunch is to write a small shell script that creates the required folder and prints the name to stdout. This allows you to use <param name="dataDumpFolder" command="your script" />. You may need to remove some whitespace before using the value.
I have a WCF service I want to trace. I have set the next lines int the Web.Config file:
<system.diagnostics>
<sources>
<source name="System.ServiceModel"
switchValue="Critical, ActivityTracing"
propagateActivity="true">
<listeners>
<add name="traceListener"
type="System.Diagnostics.XmlWriterTraceListener"
initializeData= "C:\Logs\MyCriticalTraces.svclog" />
</listeners>
</source>
</sources>
</system.diagnostics>
As you can see I just want CRITICAL messages but the File is extremely large (40 Mb every 5 minutes). It keeps getting larger and larger in a few minutes.
If I look into the file I see many messages but none seem to be Critical.
I just want to trace the Critical errors, otherwise the file would be impossible to move or open.
Any idea about this?
Sorry, I just copied-pasted that tracing code from some forum without knowing what I was doing. Then I realized that the option switchValue was wrong. I mean, I don't need the ActivityTracing log. So the line
switchValue="Critical, ActivityTracing"
Should be:
switchValue="Critical"
So the result is this:
<system.diagnostics>
<sources>
<source name="System.ServiceModel"
switchValue="Critical"
propagateActivity="true">
<listeners>
<add name="traceListener"
type="System.Diagnostics.XmlWriterTraceListener"
initializeData= "C:\Logs\MyCriticalTraces.svclog" />
</listeners>
</source>
</sources>
</system.diagnostics>
I decided to use log4net as a logger for a new webservice project. Everything is working fine, but I get a lot of messages like the one below, for every log4net tag I am using in my web.config:
Could not find schema information for
the element 'log4net'...
Below are the relevant parts of my web.config:
<configSections>
<section name="log4net"
type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
</configSections>
<log4net>
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="C:\log.txt" />
<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="100KB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level: %message%newline" />
</layout>
</appender>
<logger name="TIMServerLog">
<level value="DEBUG" />
<appender-ref ref="RollingFileAppender" />
</logger>
</log4net>
Solved:
Copy every log4net specific tag to a separate xml-file. Make sure to use .xml as file extension.
Add the following line to AssemblyInfo.cs:
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "xmlFile.xml", Watch = true)]
nemo added:
Just a word of warning to anyone
follow the advice of the answers in
this thread. There is a possible
security risk by having the log4net
configuration in an xml off the root
of the web service, as it will be
accessible to anyone by default. Just
be advised if your configuration
contains sensitive data, you may want
to put it else where.
#wcm: I tried using a separate file. I added the following line to AssemblyInfo.cs
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)]
and put everything dealing with log4net in that file, but I still get the same messages.
You can bind in a schema to the log4net element. There are a few floating around, most do not fully provide for the various options available. I created the following xsd to provide as much verification as possible:
http://csharptest.net/downloads/schema/log4net.xsd
You can bind it into the xml easily by modifying the log4net element:
<log4net
xsi:noNamespaceSchemaLocation="http://csharptest.net/downloads/schema/log4net.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
I had a different take, and needed the following syntax:
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.xml", Watch = true)]
which differs from xsl's last post, but made a difference for me. Check out this blog post, it helped me out.

I believe you are seeing the message because Visual Studio doesn't know how to validate the log4net section of the config file. You should be able to fix this by copying the log4net XSD into C:\Program Files\Microsoft Visual Studio 8\XML\Schemas (or wherever your Visual Studio is installed). As an added bonus you should now get intellisense support for log4net
In Roger's answer, where he provided a schema, this worked very well for me except where a commenter mentioned
This XSD is complaining about the use of custom appenders. It only allows for an appender from the default set (defined as an enum) instead of simply making this a string field
I modified the original schema which had a xs:simpletype named log4netAppenderTypes and removed the enumerations. I instead restricted it to a basic .NET typing pattern (I say basic because it just supports typename only, or typename, assembly -- however someone can extend it.
Simply replace the log4netAppenderTypes definition with the following in the XSD:
<xs:simpleType name="log4netAppenderTypes">
<xs:restriction base="xs:string">
<xs:pattern value="[A-Za-z_]\w*(\.[A-Za-z_]\w*)+(\s*,\s*[A-Za-z_]\w*(\.[A-Za-z_]\w*)+)?"/>
</xs:restriction>
</xs:simpleType>
I'm passing this back on to the original author if he wants to include it in his official version. Until then you'd have to download and modify the xsd and reference it in a relative manner, for example:
<log4net
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="../../../Dependencies/log4net/log4net.xsd">
<!-- ... -->
</log4net>
Actually you don't need to stick to the .xml extension. You can specify any other extension in the ConfigFileExtension attribute:
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", ConfigFileExtension=".config", Watch = true)]
#steve_mtl: Changing the file extensions from .config to .xml solved the problem. Thank you.
#Wheelie: I couldn't try your suggestion, because I needed a solution which works with an unmodified Visual Studio installation.
To sum it up, here is how to solve the problem:
Copy every log4net specific tag to a separate xml-file. Make sure to use .xml as file extension.
Add the following line to AssemblyInfo.cs:
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "xmlFile.xml", Watch = true)]
For VS2008 just add the log4net.xsd file to your project; VS looks in the project folder as well as the installation directory that Wheelie mentioned.
Also, using a .config extension instead of .xml avoids the security issue since IIS doesn't serve *.config files by default.
Have you tried using a separate log4net.config file?
I got a test asp project to build by puting the xsd file in the visual studio schemas folder as described above (for me it is C:\Program Files\Microsoft Visual Studio 8\XML\Schemas) and then making my web.config look like this:

Without modifying your Visual Studio installation, and to take into account proper versioning/etc. amongst the rest of your team, add the .xsd file to your solution (as a 'Solution Item'), or if you only want it for a particular project, just embed it there.
I noticed it a bit late, but if you look into the examples log4net furnishes you can see them put all of the configuration data into an app.config, with one difference, the registration of configsection:
<!-- Register a section handler for the log4net section -->
<configSections>
<section name="log4net" type="System.Configuration.IgnoreSectionHandler" />
</configSections>
Could the definition it as type "System.Configuration.IgnoreSectionHandler" be the reason Visual Studio does not show any warning/error messages on the log4net stuff?
I followed Kit's answer https://stackoverflow.com/a/11780781/6139051 and it didn't worked for AppenderType values like "log4net.Appender.TraceAppender, log4net". The log4net.dll assembly has the AssemblyTitle of "log4net", i.e. the assembly name does not have a dot inside, that was why the regex in Kit's answer didn't work. I has to add the question mark after the third parenthetical group in the regexp, and after that it worked flawlessly.
The modified regex looks like the following:
<xs:pattern value="[A-Za-z_]\w*(\.[A-Za-z_]\w*)+(\s*,\s*[A-Za-z_]\w*(\.[A-Za-z_]\w*)?+)?"/>
