Hi all, I wanted to post a bit about some HTrace activity that's been going on lately. Some of this stuff is not as visible, because it's going on in other git repos, rather than in HTrace itself. But it's actually just as important, or even more important, than changes to the HTrace git repo it

Re: HTrace and Go

Hi Michael, It's great that you're looking at the project! The build requirements are in BUILDING.txt, which says "Requires go version 1.3.1 or 1.4." In practice, other versions of go will probably work, we just haven't tested them. If you are using any modern version of Linux, you should be ab

Re: February 2015 Report

Thanks for putting this together, Lewis! It looks good. The only thing I would change is that while the current text says "the community appears not to have developed much with regards to attracting new community members," we do have a new community member, Abraham Elmarek, who has been doing a l

HTrace build products in Maven Central?

Hi guys, I apologize in advance that there are probably some dumb questions here. I don't know much about packaging. What's the plan for pushing HTrace 3.1.0 build products to Maven Central (once 3.1.0 is accepted)? It seems like we have 3 options: 1. fatjar that includes all dependencies in sh

Re: Few general notes on using htrace, the cmd-line interface, and htraced

he build directory from the source directory. But we can move stuff around (and probably should...). Agree that it's a little weird to have src/build, should probably have just target/ and src/ instead. Colin > St.Ack > > > > > > On Mon, Jan 19, 2015 at 10:46 PM, Colin McCabe

Re: [VOTE] htrace-3.1.0, the seventh release candidate

I downloaded the sources and did a "mvn clean" and the build/ and pkg/ directories went away. I think we just need to re-generate the tarball after doing "mvn clean". I guess that means a new RC though. best, Colin On Tue, Jan 13, 2015 at 11:56 AM, Billie Rinaldi wrote: > Yes, -1. The binari

Re: [VOTE] htrace-3.1.0, the sixth release candidate

It looks like the issue is that we depend on git in our build process, in two places: * we inject the git hash into the htraced binary so that it can be queried * we use "git clean" as part of "mvn clean" Since our source tarball doesn't have a .git directory, these uses won't work. I guess our o

I verified the signature, untarred, ran mvn test with no problems. I did see that we are leaking a few jackson classes on to the CLASSPATH in htrace-core: jar tvf ./htrace-core/target/htrace-core-3.1.0.jar 2487 Wed Dec 31 14:29:18 PST 2014 org/apache/htrace/fasterxml/jackson/core/util/Mini
