I'm trying to implement Lucene search in Sitecore. Using the default Sitecore.Search implementation, I should be able to get a reference to the index defined in my config file and call index.Rebuild.
I tried using the RebuildDatabaseCrawlers script from the AdvancedDatabaseCrawler, but everytime I call Rebuild, it fails.
The error I receive is:
Lock obtain timed out: SimpleFSLock#C:\sites\MySite\Data\indexes\__mysite\write.lock
I've tried changing permissions (including giving Everyone full perms), restarting databases and IIS, all to no avail. I've also tried stripping my search configuration section down to the bare minimum, with the same result.
Unfortunately I don't have any visibility into what the index.Rebuild() method does, as its inside the Sitecore.Search assembly.
The issue ended up being related to configuration.
Specifically, when trying to remove all superfluous Sitecore.Data.Indexing references from the configuration files after determining that i didn't need both Sitecore.Search and Sitecore.Data.Indexing, I had commented out the following line:
<configuration>
<appSettings>
<add key="Lucene.Net.FSDirectory.class" value="Sitecore.Data.Indexing.FSDirectory, Sitecore.Kernel"/>
</appSettings>
</configuration>
That needs to be there.
Try to adjust the permissions for c:\Temp for your app pool user, e.g. Network Service
You can also try to do the same for: c:\windows\microsoft.net\framework\{version}\Temporary ASP.NET Files

I am trying to publish as ASP.NET Core project with a hosting provider that supports ASP.NET Core. I am getting 500 Internal Server Error which I believe is very common. So I searched through the internet and various forums and then I checked the processPath="%LAUNCHER_PATH%" arguments="%LAUNCHER_ARGS%" in web.config and they look to be correctly converted with processPath="dotnet" and arguments=".\MyApplication.dll".
I also checked the connection string and it points to production DB server that's working. I confirmed the DB connection by changing the connection string to production DB and running project local. It works and I get the production DB access.
I also tried to get the error info by using the below in my Startup.cs (irrespective of env):
app.UseDeveloperExceptionPage();
app.UseDatabaseErrorPage();
app.UseBrowserLink();
I have also enabled stdoutLog in web.config, but I don't see that folder either:
stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout"
I also tried to change applicationUrl and launchUrl in launchSettings.json to my prod Url, but that didn't work as well.
So, the 500 Internal Server Error refuses to go away, and I still don't have a useful error message. The page just says:
Oops.
500 Internal Server Error
An error occurred while starting the application.
I would really appreciate if someone could help me here.
I have also enabled stdoutLog in web.config as but I don't see that folder either:
stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout"
There is one trick here - you must create both folders logs and stdout manually - then and only then IIS will create log file inside logs folder (not stdout as you could expect) - don't ask me why, because I don't know why ;)
Oops. 500 Internal Server Error An error occurred while starting the application.
Usually, means problems with a configuration in Startup.cs - the most common problems include an issue with DB itself, an issue with migrations (if you are using Code First approach), problems with appsettings.js, problems with Social Logins credentials (like missing SecretKey)...
Please refer to log file in .\logs\stdout - this is the quickest way to find details about the problem :)
app.UseDeveloperExceptionPage();
app.UseDatabaseErrorPage();
Those will work after your WebApp fully started, but not while starting the application.
in web.config file change modules="AspNetCoreModuleV2" to modules="AspNetCoreModule"

Thanks to Lukasz for his comments. I was able to see the log and it stated that "ClientId option must be provided". The problem was with the UserSecrets. Since secrets.json is only available in Development, there were no secrets found in Production. Once I had the secrets in my appSettings.json, it worked fine.
Moreover, To replicate this in Local environment, just go to Project properties and change the environment variable ASPNETCORE_ENVIRONMENT to 'Production' and run in local. This will replicate the 500 Internal Server Error in local and you'll get the error message.
Also, ensure that the ASP.NET Core Windows Server Hosting bundle is installed. THis creates a reverse proxy between IIS and the Kestral server.

I would like to add some more info to #Lukasz Makowej answer.
I found out the reason why to have to create the folder, in microsoft documentation it is said that:
stdoutLogFile - Optional string attribute.
".....Any folders provided in the path must exist in order for the module to create the log file...."
So you have to create it yourself :)
Check it out here:
https://learn.microsoft.com/en-us/aspnet/core/host-and-deploy/aspnet-core-module?view=aspnetcore-2.0
I also must said that in my case I had to validate that the web-site had the permissions to access to the "log" folder.
Make sure your web.config is good. I've been stomped more than once by a syntactically good web.config that referred to a module (Rewrite) that wasn't on the server. No error messages anywhere, other than the 500 response error.
Std log wasn't working for me, I had to uninstall all .ENT Core runtime / SDK versions from the server and my local to install the latest one and it worked after publishing everything again from scratch.
Another thing that helped was binding the IIS app to port 5000 without any dns so it actually showed me errors on http://localhost:5000
Encountered this issue yesterday, we also had no logging, no eventlog message whatsoever.
Then we checked the site's authentication settings via the IIS-manager to double-check the settings. And pop suddenly a popup with an error message 'Error on line XXXX'.
Turned out the configuration section was locked in the website's config at server-level.
So try unlocking the relevant IIS configuration settings at server level, as follows:
Open IIS Manager
Select the server in the Connections pane
Open Configuration Editor in the main pane
In the Sections drop down, select the section to unlock, e.g. system.webServer => security => authentication
Click Unlock Attribute in the right pane
Repeat for any other settings which you need to unlock
Restart IIS (optional) - Select the server in the Connections pane, click Restart in the Actions pane
In a typical SignalR view it includes...
<script src="/signalr/hubs"></script>
I'm trying to get my head around SignalR and want to look at the javascript within this folder. But I cant find it within my project.
Also, I understand this contains javascript that is generated customised for my hub class etc. Is this correct?
The /signalr/hubs file is dynamically created by the SignalR server when the app boots up. Since the SignalR server hangs off of the /signalr endpoint it then generates the /hubs ontop of it.
Here's how SignalR 2.0.2 generates the file at a high level: https://github.com/SignalR/SignalR/blob/2.0.2/src/Microsoft.AspNet.SignalR.Core/Hubs/DefaultJavaScriptProxyGenerator.cs .
And here's where it determines that the request is to /signalr/hubs (in 2.0.2) https://github.com/SignalR/SignalR/blob/2.0.2/src/Microsoft.AspNet.SignalR.Core/Hubs/HubDispatcher.cs#L235-L253
Finally to answer your last question, it absolutely does. This is why it's dynamically generated. If you'd ever like to get a physical file that represents the /signalr/hubs endpoint you can follow the instructions here: http://www.asp.net/signalr/overview/signalr-20/hubs-api/hubs-api-guide-javascript-client#manualproxy
Hope this helps!
You are correct. It's dynamically generated so that's why you can't see it in visual studio. Enable directory browsing in your web.config by adding
<system.webServer>
<directoryBrowse enabled="true"/>
</system.webServer>
You can then navigate to localhost/signalr/hubs to see the file contents.
This is a fresh install of Raven #2230, running on IIS8/Win8. When studio starts it offers to create new database, then browser pops up credentials window (401).
Web.config has add key="Raven/AnonymousAccess" value="All"/ set. Also tried add key="Raven/AnonymousUserAccessMode" value="All"/ as per documentation.
Anonymous Authentication on site is enabled, so is Windows Authentication.
Added Raven.Bundles.Authorization.dll to plugins folder (not sure if needed, but didn't make any difference).
Am I missing something ?
RavenDB as of today, is on version 2750 (stable). Upgrade and this issue should be fixed.
The way to do this is to set the AnonymousAccess setting in web.config to Admin:
<add key="Raven/AnonymousAccess" value="Admin"/>
You should change this back to All once you have created your database.
some of my web applications write to the disk on the web server. The paths change depending on location, prod and dev, etc. I used to store the paths in web.config under configuration / appSettings like:
<add key='PDFOutPutPath' value='C:\Temporary_Web_Files\PDFTempDocs\'/>
And then get them like this:
path = ConfigurationSettings.AppSettings('PDFOutPutPath')
Now in .Net 4, I get compile warnings about this being depreciated, so I found some instructions telling me to add a configuration file, move my values to it like so:
<configuration>
<appSetings>
<add key='PDFOutPutPath' value='C:\Temporary_Web_Files\PDFTempDocs\'/>
</appSettings>
</configuration>
and use configuration manager like so:
ConfigurationManager.AppSettings( 'PDFOutPutPath' )
However, this does not work. I'm not sure if I'm supposed to be using the configuration manager for this or not - If not, where do you put stuff like this? I have System.Configuration referenced, so this in not my issue.
So it appears the instructions you followed were a bit misleading.
You do not need a second file, you should delete the app.config file. You can place all of the configuration values in the web.config. Just make sure the config items are in the <appSetings> node. But you should continue to use the ConfigurationManager class within the code to access the values.
Ever since upgrading to Visual Studio 2010, I'm running into an issue where the first web request of any type (WebRequest, WebClient, etc.) hangs for about 20 seconds before completing. Subsequent calls work quickly. I've narrowed down the problem to a proxy issue.
If I manually disable proxy settings, I don't experience this delay:
Dim wrq As WebRequest = WebRequest.Create(Url)
wrq.Proxy = Nothing
What's strange is that there are no proxy settings enabled on this machine in Internet Options. What I'm wondering is if there is a way to disable proxy settings for my entire project in one shot without explicitly disabling as above for every web object.
The main reason I want to be able to do this is that I'm trying to use an API (http://code.google.com/p/google-api-for-dotnet/) which uses web requests, but does not provide any way to manually disable proxy settings.
I have found some information suggesting that I need to add some proxy information to the app.config file, but I get errors building my program if I make an edits to that file.
Can anyone point me in the right direction?
Brent - that's the correct solution : adding a defaultProxy element to your application's configuration file.
So for a website, it's the web.config. For an .exe application, it's .config.
And those settings are also correct :-
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.net>
<defaultProxy enabled="false" useDefaultCredentials="false">
<proxy/>
<bypasslist/>
<module/>
</defaultProxy>
</system.net>
</configuration>
Instead of turning off the proxy setting altogether you can try using the bypasslist to turn it off for the servers that you're having problems with.
See http://msdn.microsoft.com/en-us/library/kd3cf2ex.aspx for details and a sample.
If you're having problems changing the app.config I suggest posting the errors and possibly the app.config as well.
