I'm looking for the proper way to set the trace-id for a Span in Brave. Pre-Brave we had:
Span span = Span.builder().traceId(someLong).build();
What's the brave equivalent? I have the following, but it's obviously not correct, as there's no way to set the Span's context explicitly.
Span span = tracer.nextSpan().start();
span.context().toBuilder().traceId(someLong).build();
You can use the TraceContext Builder to set your own TraceId.
TraceContext traceContext = TraceContext.newBuilder().traceId(traceId).build();
Span span =
this.tracing.tracer()
.toSpan(traceContext)
.name("application.name"))
.start();
This is optional though; you could let the Tracer generate its own traceId when you create a new Span :-
this.tracing.tracer().nextSpan().name("application.name").start();
We can build up TraceContext first and then we can use this to create TraceContextOrSamplingFlags which can be then used to create Span as follws:
TraceContext traceContext = TraceContext.newBuilder()
.traceId(someTraceId)
.spanId(someSpanId)
.build();
Span span = tracer.nextSpan(TraceContextOrSamplingFlags.create(traceContext))
.name(someName).start();
You can do it like this brave.Span span = tracer.nextSpan().name("name").traceId(someLong).start();
Or more advance
brave.Span span = tracer.nextSpan().name("name").traceId(someLong);
try (SpanInScope ws = tracer.withSpanInScope(span.start())) {
// do sth
} finally {
span.finish();
}

With the ToolManager I can get the the current placement, the context and of course, the Site through the SiteService. But I want to get the current SitePage properties the user is currently accessing.
This doubt can be extended to the current Tool properties with a
little more emphasis considering that once I have the Tool I could not
find any methods covering the its properties.
I could get the tool properties and I'm using it (it is by instance) through Properties got with sitepage.getTool(TOOLID).getConfig(). To save a property, I'm using the ToolConfiguration approach and saving the data after editing with the ToolConfiguration.save() method. Is it the correct approach?
You can do this by getting the current tool session and then working your way backward from that. Here is a method that should do it.
public SitePage findCurrentPage() {
SitePage sp = null;
ToolSession ts = SessionManager.getCurrentToolSession();
if (ts != null) {
ToolConfiguration tool = SiteService.findTool(ts.getPlacementId());
if (tool != null) {
String sitePageId = tool.getPageId();
sp = s.getPage(sitePageId);
}
}
return sp;
}
Alternatively, you could use the current tool to work your way to it but I think this method is harder.
String toolId = toolManager.getCurrentTool().getId();
String context = toolManager.getCurrentPlacement().getContext();
Site s = siteService.getSite( context );
ToolConfiguration tc = s.getTool(toolId);
String sitePageId = tc.getPageId();
SitePage sp = s.getPage(sitePageId);
NOTE: I have not tested this code to make sure it works.
I am very comfortable with UIMA, but my new work require me to use GATE
So, I started learning GATE. My question is regarding how to calculate performance of my tagging engines (java based).
With UIMA, I generally dump all my system annotation into a xmi file and, then using a Java code compare that with a human annotated (gold standard) annotations to calculate Precision/Recall and F-score.
But, I am still struggling to find something similar with GATE.
After going through Gate Annotation-Diff and other info on that page, I can feel there has to be an easy way to do it in JAVA. But, I am not able to figure out how to do it using JAVA. Thought to put this question here, someone might have already figured this out.
How to store system annotation into a xmi or any format file programmatically.
How to create one time gold standard data (i.e. human annotated data) for performance calculation.
Let me know if you need more specific or details.
This code seems helpful in writing the annotations to a xml file.
http://gate.ac.uk/wiki/code-repository/src/sheffield/examples/BatchProcessApp.java
String docXMLString = null;
// if we want to just write out specific annotation types, we must
// extract the annotations into a Set
if(annotTypesToWrite != null) {
// Create a temporary Set to hold the annotations we wish to write out
Set annotationsToWrite = new HashSet();
// we only extract annotations from the default (unnamed) AnnotationSet
// in this example
AnnotationSet defaultAnnots = doc.getAnnotations();
Iterator annotTypesIt = annotTypesToWrite.iterator();
while(annotTypesIt.hasNext()) {
// extract all the annotations of each requested type and add them to
// the temporary set
AnnotationSet annotsOfThisType =
defaultAnnots.get((String)annotTypesIt.next());
if(annotsOfThisType != null) {
annotationsToWrite.addAll(annotsOfThisType);
}
}
// create the XML string using these annotations
docXMLString = doc.toXml(annotationsToWrite);
}
// otherwise, just write out the whole document as GateXML
else {
docXMLString = doc.toXml();
}
// Release the document, as it is no longer needed
Factory.deleteResource(doc);
// output the XML to <inputFile>.out.xml
String outputFileName = docFile.getName() + ".out.xml";
File outputFile = new File(docFile.getParentFile(), outputFileName);
// Write output files using the same encoding as the original
FileOutputStream fos = new FileOutputStream(outputFile);
BufferedOutputStream bos = new BufferedOutputStream(fos);
OutputStreamWriter out;
if(encoding == null) {
out = new OutputStreamWriter(bos);
}
else {
out = new OutputStreamWriter(bos, encoding);
}
out.write(docXMLString);
out.close();
System.out.println("done");
I have several urls:
/dave
/davina
/dave/chris
/davina/peter
I have entries for all of them in my routes, an example of this is:
routes.dave.route = /dave
routes.dave.defaults.module = default
routes.dave.defaults.controller = person
routes.rcp.defaults.action = index
routes.davina.route = /dave/chris
routes.davina.defaults.module = default
routes.davina.defaults.controller = person
routes.davina.defaults.action = index
I think you can see straight away that I have a duplication issue. Is there a way of combining multiple urls into a single route?
I have played around with using /:person but I also have other content aswell not going to person controller.
routes.person.route = /:personname
routes.person.defaults.module = default
routes.person.defaults.controller = person
routes.person.defaults.action = index
routes.person.reqs.personname = "^[a-zA-Z0-9]+$"
Urls such as /search?person=dave which goes off to the search controller is obviously being killed by the expression above.
Can I express the requirement as a list? "dave|davina|etc" or is there another magical zend method of doing this?
UPDATE:
I was playing around and came across this partial solution:
routes.person.route = /:personname
routes.person.defaults.module = default
routes.person.defaults.controller = person
routes.person.defaults.action = index
routes.person.reqs.personname = "(dave|davina)"
routes.person.route = /:person/:personname
routes.person.defaults.module = default
routes.person.defaults.controller = person
routes.person.defaults.action = index
routes.person.reqs.personname = "(chris|peter)"
I am going to run with this for the moment as is satisfies my requirements but I will leave this open(at least for a day) for anyone to offer there advice. The main issues is that both lists are going to grow, which will eventually cause an issue.
I think I may have the anwser for that.
In ZF, the routes are matched in reverse-order. So the last defined route, is the first matched.
In this case, you should define your /:person/:personname route, then define the others static routes like about page, contact page, etc.
If I understand Zend correctly, it should work. This do that in clear:
url=/about
match route "/about"
url=/david/parker
match route "/:person/:personname"
not "/about" or "/contact"
I would like to increase the MaxBufferSize, MaxBufferPoolSize, ReceivedMessageSize, along with the readerQuotas maxDepth="2147483646" maxStringContentLength="2147483646" maxArrayLength="2147483646" maxBytesPerRead="2147483646" maxNameTableCharCount="2147483646", It is my understanding that I must change these parameters in the registration process. But I see no examples anywhere on doing this.
I would appreciate any help on this matter.
Don't know if you found an answer to this or not but it would look something like this:
builder.Register(
container =>
new ChannelFactory<TService>(
new WSHttpBinding { TransactionFlow = supportTransactionFlow,
MaxReceivedMessageSize = 2147483646,
ReaderQuotas = {
MaxStringContentLength = 2147483646,
MaxDepth = 2147483646,
MaxArrayLength= 2147483646 }},
endpointAddress)).InstancePerDependency();
I am using the Fluent API to handle various configuration options for Logging using EntLib.
I am building up the loggingConfiguration section manually in code. It seems to work great except that the RollingFlatFileTraceListener doesn't actually Roll the file. It will respect the size limit and cap the amount of data it writes to the file appropriately, but it doesn't not actually create a new file and continue the logs.
I've tested it with a sample app and the app.config and it seems to work. So I'm guess that I am missing something although every config option that seems like it needs is there.
Here is the basics of the code (with hard-coded values to show a config that doesn't seem to be working):
//Create the config builder for the Fluent API
var configBuilder = new ConfigurationSourceBuilder();
//Start building the logging config section
var logginConfigurationSection = new LoggingSettings("loggingConfiguration", true, "General");
logginConfigurationSection.RevertImpersonation = false;
var _rollingFileListener = new RollingFlatFileTraceListenerData("Rolling Flat File Trace Listener", "C:\\tracelog.log", "----------------------", "",
10, "MM/dd/yyyy", RollFileExistsBehavior.Increment,
RollInterval.Day, TraceOptions.None,
"Text Formatter", SourceLevels.All);
_rollingFileListener.MaxArchivedFiles = 2;
//Add trace listener to current config
logginConfigurationSection.TraceListeners.Add(_rollingFileListener);
//Configure the category source section of config for flat file
var _rollingFileCategorySource = new TraceSourceData("General", SourceLevels.All);
//Must be named exactly the same as the flat file trace listener above.
_rollingFileCategorySource.TraceListeners.Add(new TraceListenerReferenceData("Rolling Flat File Trace Listener"));
//Add category source information to current config
logginConfigurationSection.TraceSources.Add(_rollingFileCategorySource);
//Add the loggingConfiguration section to the config.
configBuilder.AddSection("loggingConfiguration", logginConfigurationSection);
//Required code to update the EntLib Configuration with settings set above.
var configSource = new DictionaryConfigurationSource();
configBuilder.UpdateConfigurationWithReplace(configSource);
//Set the Enterprise Library Container for the inner workings of EntLib to use when logging
EnterpriseLibraryContainer.Current = EnterpriseLibraryContainer.CreateDefaultContainer(configSource);
Any help would be appreciated!
Your timestamp pattern is wrong. It should be yyy-mm-dd instead of MM/dd/yyyy. The ‘/’ character is not supported.
Also, you could accomplish your objective by using the fluent configuration interface much easier. Here's how:
ConfigurationSourceBuilder formatBuilder = new ConfigurationSourceBuilder();
ConfigurationSourceBuilder builder = new ConfigurationSourceBuilder();
builder.ConfigureLogging().LogToCategoryNamed("General").
SendTo.
RollingFile("Rolling Flat File Trace Listener")
.CleanUpArchivedFilesWhenMoreThan(2).WhenRollFileExists(RollFileExistsBehavior.Increment)
.WithTraceOptions(TraceOptions.None)
.RollEvery(RollInterval.Minute)
.RollAfterSize(10)
.UseTimeStampPattern("yyyy-MM-dd")
.ToFile("C:\\logs\\Trace.log")
.FormatWith(new FormatterBuilder().TextFormatterNamed("textFormatter"));
var configSource = new DictionaryConfigurationSource();
builder.UpdateConfigurationWithReplace(configSource);
EnterpriseLibraryContainer.Current = EnterpriseLibraryContainer.CreateDefaultContainer(configSource);
var writer = EnterpriseLibraryContainer.Current.GetInstance<LogWriter>();
DateTime stopWritingTime = DateTime.Now.AddMinutes(10);
while (DateTime.Now < stopWritingTime)
{
writer.Write("test", "General");
}
