Some questions about solr source code
Dear Solr Developer,
I am a Chinese Software developer and I having been using solr for nearly
4years.First Thank u for your continuous effort on improving solr. Recently I
began to read the source code because I am very curious about how it works. But
I encountered many questions which I spend much time to thinkd about but
failed.I hope u can explain for me.I list the question below.I am using solr
6.6.0.Please parden me for my poor English.
1.In the method boolean handleVersions(ShardResponse srsp) of the class
org.apache.solr.update.PeerSync,I can not understand the variant 'boolean
completeList = otherVersions.size() < nUpdates; ',I think it is just the
opposite.Maybe I misunderstand the whole passage
2.Also in the class org.apache.solr.update.PeerSync,the method
'handleVersionsWithRanges'??I think there is a bug in line 555
while ((otherUpdatesIndex < otherVersions.size()) &&
(Math.abs(otherVersions.get(otherUpdatesIndex)) <
Math.abs(ourUpdates.get(ourUpdatesIndex {
x
}
otherUpdatesIndex are always < otherVersions.size(),because it starts with
otherVersions.size() -1 and it never get bigger,so there no point in checking
this.I think it should be replaced with 'otherUpdatesIndex >= 0'
I am not an expert of Solr.May be I misunderstand the whole class or method
so please tell me directly if I am wrong.
Please parden me again for my poor English.I am looking forward for your
replay. Thank u again for your great effort to develop and improve Solr.
Best Regards
Guohua Wu
Re: Navigating through Solr Source Code
Hello. Emir mentioned about starting from the feature/concept. If you haven't come across it yet then the slides and/or recording of Hoss's "Lifecycle of a Solr Search Request" talk may be of interest - http://home.apache.org/~hossman/ has links. Erick mentioned about getting a sense via unit tests. The HelloWorldSolrCloudTestCase could be a starting point for that - https://github.com/apache/lucene-solr/blob/releases/lucene-solr/7.3.1/solr/core/src/test/org/apache/solr/HelloWorldSolrCloudTestCase.java is a link to it.

As Erick has said, the rabbit hole is very deep.I've been looking into it for a few years now. There are parts of it that are a complete mystery.

The solr/webapp/web/WEB-INF/web.xml file in the source code checkout is what loads SolrDispatchFilter and a few other classes when Solr starts. Thanks, Shawn

Re: Navigating through Solr Source Code
Another useful trick is the class hierarchy displays most modern IDE's have available to get a sense of what class is where. And I second Emir's comment about picking some feature. _Nobody_ knows all the Solr code, and that's not even including Lucene. It's big, very big. So pick a feature you want to understand and/or improve and stick to that or you'll go nuts. And a great way to get a sense of how a feature works is to find the unit test that exercises it and just step through it in the debugger. And if there's no unit test, another great way to do things would be to _create_ a unit test. Or fix some of the BadApple tests, but those will be pretty hairy Best, Erick On Mon, May 21, 2018 at 7:18 AM, Emir Arnautović wrote: > Hi, > I would start from the feature/concept that I find documentation to be vague. > If you think that everything is like that, I would not start with code just > yet and would focus on understanding high level concepts first.

Re: Navigating through Solr Source Code
Hi, I would start from the feature/concept that I find documentation to be vague. If you think that everything is like that, I would not start with code just yet and would focus on understanding high level concepts first. Also, you need to figure out if some feature is Solr or Lucene and if it is Solr if cloud mode is involved or not. I would suggest that you start simple tog get familiar with Solr concepts. Set up local dev env, put some break point and start following it.

Navigating through Solr Source Code
Hi, As the documentation around Solr is limited, I am thinking to go through the source code and understand the various bits and pieces. However, I am a bit confused on where to start as I my developing skills are a bit limited. Any thoughts on how best to start / where to start looking into Solr source code? Thanks
Re: com.ibm.icu dependency errors when building solr source code
Running "ant eclipse" or "ant test" in verbose mode will provide you the exact lib in ivy2 cache which is corrupt. Delete that particular lib and run "ant" again. Also don't try to get out / exit "ant" commands via Ctrl+C or Ctrl+V while it is downloading the libraries to ivy2 folder.
Re: com.ibm.icu dependency errors when building solr source code
Sometimes I've seen something like this when the ivy cache is corrupt. It's a pain since it takes a while to re-download things, but you might try to remove that entire cache. On my mac it's 'rm -rf ~.ivy2/cache' Erick On Thu, Jun 22, 2017 at 3:39 AM, Susheel Kumar wrote: > Hello, > > Am i missing something or the source code is broken.

Re: Want to modify Solr Source Code
Hi, if you followed what is written in the link that Gora suggested, you should have a workspace without errors. Eclipse compiler allows for incremental builds, that is, all code is incrementally compiled as soon as you finish typing. So if you inserted those lines and you don't see any error then that means they have been successfully compiled.

Re: Want to modify Solr Source Code
Hi Anshum, The reason behind to edit source code is that I am using spell check component on solr. I have implemented it and it is working fine.. But something suggestion frequency goes vary. I have explain that it into this - http://stackoverflow.com/questions/28857915/original-frequency-is-not-matching-with-suggestion-frequency-in-solr. Please check it.. And now, I am thinking that if I will able to add hitcount instead of freq in suggestion then I will be helpful for my purpose.

Hi Nitin, Do you intend to browse the code? If you really want to modify the code, can you tell us about what exactly is it that you're trying to achieve? Can you clarify on how you want to test Solr? If so, do you plan on running the tests that Solr ships with or do you have your own tests?

Re: Want to modify Solr Source Code
Is your concern that you want to be able to modify source code just on your machine or that you can't for some reason install svn? If it's the former, even if you checkout using svn, you can't modify anything outside the machine as changes can be checked in only by the committers of the project. You will need to raise a JIRA for the changes to go back in as described by the wiki page. If the latter, try downloading the source code using the downloads section in https://lucene.apache.org/solr and choose the download which ends as -src.tgz, that has the source bundled as a single file.

Hi, I want to modify the solr source code. I don't have any idea where source code is available. I want to edit source code. How can I do ? Any help please...

The Lucene/Solr project is licensed under the Apache License, version 2.0. http://www.apache.org/licenses/LICENSE-2.0 http://www.apache.org/foundation/license-faq.html#WhatDoesItMEAN The generally accepted way to contribute a bugfix to the project is to find (or create) the appropriate issue in Jira, then attach your patch to it. Ideally you will check out the trunk branch from SVN and create your patch against that with the "svn diff" tool, but the stable branch (branch_4x currently) will do just as well. Just be sure there's enough info accompanying the patch for us to identify the exact branch/revision used to build it. http://wiki.apache.org/solr/HowToContribute There are other methods, like the mailing list, a pull request for the github mirror, etc... but Jira and a patch from SVN are the best way.

Solr source code
Hi, What is the process regarding modify Solr source code (legal part)? In addition, who should I update for this bug and fix so Solr team will consider using it. Thanks, Shay.
Re: How to edit / compile the SOLR source code
Jonathan: If you're working off trunk (and 3x), btw, there's a *great* addition especially if you use IntelliJ (I haven't personally worked with the Eclipse, there's a target for that too). Just get the source. Go to the top level (e.g. apache-trunk). Execute "ant idea". Open IntelliJ and point it at the directory via "open project". Go into project settings and set your compiler. Wait for Idea to finish indexing, etc. Run tests. Use ^N to find classes. Step through the code by debugging unit tests. Apart from the one trick of "opening project" on the folder rather than a cute little IntelliJ icon (select the root directory), the *only* thing you have to do is set your compiler. After having to spend *days* setting up the IDE on some projects this is a dream. Apart from getting the source and waiting for Idea to do its first-pass indexing, I can set up a new IDE instance in, maybe, 5 minutes. Sweet! And, BTW, the IntelliJ "community edition" is free and open-source now.

Re: How to edit / compile the SOLR source code
Hmm... sorry for the bad link... looks like somehow I inserted a bogus letter: "artiicles" instead of "articles" in the url. http://www.lucidimagination.com/developers/articles/setting-up-apache-solr-in-eclipse At any rate, are you using Ant to compile? Literally all you have to do is run the command "ant example" in the directory containing your build.xml file (it's the top-level directory), and everything will be recompiled and repackaged for you. If you are having trouble writing over old jar files, try running "ant clean" first, though I haven't had trouble with this in the past. Here's the full list of ant commands for the Solr project that you can run: usage: [echo] Welcome to the Solr project! [echo] Use 'ant example' to create a runnable example configuration. [echo] Use 'ant run-example' to create and run the example. [echo] And for developers: [echo] Use 'ant clean' to clean compiled files. [echo] Use 'ant compile' to compile the source code. [echo] Use 'ant dist' to build the project WAR and JAR files. [echo] Use 'ant generate-maven-artifacts' to generate maven artifacts. [echo] Use 'ant package' to generate zip, tgz, and maven artifacts for dist ribution. [echo] Use 'ant luke' to start luke. see: http://www.getopt.org/luke/ [echo] Use 'ant test' to run unit tests. After you run one of the build commands, check in the "dist" directory for your repackaged jars and war file. -Trey On Fri, Mar 12, 2010 at 8:33 PM, wrote: > Hi Trey, > > The below mentioned link doesn't work anymore but I figured out a way to > make the SOLR work in Eclipse. > > I also modified the solrqueryparser.java file and everything works fine in > Eclipse but I am not sure how to implement this change in the Jar file > (apache-solr-core-dev.jar).

Re: Need help in deploying the modified SOLR source code
do `ant clean dist` within the solr source and use the resulting war file, though in the future you might think about extending the built in parser and creating a parser plugin rather than modifying the actual sources see http://wiki.apache.org/solr/SolrPlugins#QParserPlugin for more info --joe On 03/12/2010 07:34 PM, JavaGuy84 wrote: Hi, I had made some changes to solrqueryparser.java using Eclipse and I am able to do a leading wildcard search using Jetty plugin (downloaded this plugin for eclipse)..

Re: How to edit / compile the SOLR source code
Eric, Thanks a lot for your reply. I was able to successfully hack the query parser and enabled the leading wild card search. As of today I hacked the code for this reason only, I am not sure how to make the leading wild card search to work without hacking the code and this type of search is the preferred type of search in our organization. I had previously searched all over the web to find out 'why' that feature was disabled as default but couldn't find any solid answer stating the reason. In one of the posting in nabble it was mentioned that it might take a performance hit if we enable the leading wild card search, can you please let me know your comments on that? But I am very much interested in contributing some new stuff to SOLR group so I consider this as a starting point..

Re: How to edit / compile the SOLR source code
See Trey's comment, but before you go there. What about SOLR's wildcard searching capabilities aren't working for you now? There are a couple of tricks for making leading wildcard searches work quickly, but this is a solved problem. Although whether the existing solutions work in your situation may be an open question... Or do you have to hack into the parser for other reasons?

Re: How to edit / compile the SOLR source code
Yep, as you've discovered, the import from ant build file doesn't work for the solr build.xml in eclipse. There is an excellent how-to for getting Solr up and running in Eclipse for debugging purposes here: http://www.lucidimagination.com/developers/artiicles/setting-up-apache-solr-in-eclipse Once you have the setup in place from the above tutorial, you can then go to any of the Solr Jar files and attach the source, which will allow you to debug into and modify the Solr code. If you need to step into any of the lucene code you'll have to pull it down separately, but you can attach the same way. The last step (after you've made your changes) is that you would just need to rebuild with Ant (run "ant" from the directory containing the build.xml file to see the build options for Solr). I think that just running "ant example" there should do the trick. -Trey On Thu, Mar 11, 2010 at 12:07 PM, JavaGuy84 wrote: > > Hi, > > Sorry for asking this very simple question but I am very new to SOLR and I > want to play with its source code. > > As a initial step I have a requirement to enable wildcard search (*text) in > SOLR.

How to edit / compile the SOLR source code
Hi, Sorry for asking this very simple question but I am very new to SOLR and I want to play with its source code. As a initial step I have a requirement to enable wildcard search (*text) in SOLR. I am trying to figure out a way to import the complete SOLR build to Eclipse and edit QueryParsing.java file but I am not able to import (I tried to import with ant project in Eclipse and selected the build.xml file and got an error stating javac is not present in the build.xml file). Can someone help me out with the initial steps on how to import / edit / compile / test the SOLR source? Thanks a lot for your help!!!
