: Artifacts are located here: http://s.apache.org/solrcene31rc0
Finally got a chance to look at 3.1 rc0.
my comments are below -- they are in the order i encountered them ...
stream of conciousness. Note that this was my first real chance to look
at the new packaging work folks have been doing to deal with the merged
dev tree (ie: the solr source only packaging, and how we include the
lucene jars in solr releases, etc...). I also have to confess being
woefully behind on reading hte dev list and jira, so forgive me if any of
this has already been discussed / dealt with...
The short summary, i'm a -1 for these RC0 packages....
I focused on the *.tgz files, assuming (for now) that the zip files are
consistent....
####
I started with apache-solr-3.1.0-src.tgz
The first thing that jumped out at me when i unpacked it was that the
directory structure i get was definitley not what i was expecting. As a
committer familiar with how the tree works, i understand what these
directories are, but i suspect this may confuse folks who have downloaded
solr in the past, and those that haven't are going to be double confused.
At a minimum the fact that there is no top level README.txt file seems
like a major oversight that we should definitely deal with.
It also seems like we should probably have a README.txt file in dev-tools
(may not be needed if a top level README.txt explains it, but it still
seems like a good idea)
looking in the "solr" directory, i look at it's README.txt file, and see
the section "Files Included In Apache Solr Distributions" it refers to a
lot of stuff that is not actaully included in the distribution (because
this is the *src* only distribution). it's one thing to assume people
downloading the *src* package will understand why the war nad jar aren't
in solr/dist/ but we also refer to a "docs" directory that doesn't exist
until they build it.
If we really want to ship a Solr src only package (which i think it's a
great idea) we need to figure out a way to rework/structure this
README.txt file to make sense for both cases (or ship two differnet ones
-- but that seems like a bad idea) ... we could start by moving the
"Instructions for Building Apache Solr from Source" up and rewording the
"Files Included" section ... but even before that i notice we refer to
docs/tutorial.html in the "Getting Started" section
looking only at the src release, i couldn't even find any documentation on
how to build the tutorial and other files -- again: since this is a src
only release, it may be ok to only include the "src" of the tutorial, but
we should at least mention somewhere how to build it.
After running "ant test" from the top level, and "ant example" in the solr
dir, i had a working example dir that seemed to be functioning fine, but i
still had no javadocs for solr. when i tried to run "ant javadoc-all" in
the solr directory, javadoc actaully failed with a DocletAbortException
stack trace because of a FileNotFoundException when trying to copy
./build/docs/api/prettify/stylesheet+prettify.css (i have a
./build/docs/api/prettify/ but it's empty ... not sure what target was
expected to populate it)
switching tracks, i looked at solr's CHANGES.txt I noticed a few small
things...
* under the "Versions of Major Components" we list "Apache Lucene trunk"
* below the 3.1 changes is a list of 1.4.0 changes -- but no 1.4.1
changes?
* we had discussed on the dev list that we should stop including changes
from older "major" versions (ie: 3.x CHANGES.txt would only list things
from 3.0 on) ... i thought i remembered people agreeing that was agood
idea, but maybe i was imaginging that.
As i mentioned -- most of the issues were really about documentation and
expectation setting for a "src" release. the README and ant task
descriptions we have were never really written with that idea in mind.
####
Next I looked at apache-solr-3.1.0.tgz
Other then the minor CHANGES.txt stuff mentioned above, this package made
much more sense when i first unpacked it. There is a top level
README.txt, and most things mentioned in the README.txt file seemed to
exist -- dist and docs. Looking at the tutorial, i noticed the first
glitch: it lists the Solr version as "3.0.0.2011.03.06.20.12.33" (which i
know means it wasn't regenerated with the forrest properties set by ant).
Other then that, the tutorial looks good, the example seems to work, and
the link from the tutorial to the javadocs works and i can browse them
just fine.
Then I realized there was no "src" directory. i'm not sure if this was
intentional (don't all of our releases need to include the source, even
the binary ones?) but at the very least we have a problem with the
README.txt which says the src should be there and that you should be able
to rebuild it with and (except that we also don't have a build.xml file
even if we had the source)
This binary distribution also seems to be more redundent then it needs to
be with the jars, everything in dist/ seems to be duplicated in dist/maven
-- again, maybe this was intentional, but if so why? ... if i wanted the
maven jars, wouldn't have just downloaded them from maven instead of
downloading the binary release? is there a value add to including them in
both directory structures?
(at this point i also discovered that there are "sources" jars in the
maven directory, so we are in fact including the source i nthe binary
releasees -- but if this is intentionally how we want to include them (and
the maven jars aren't a mistake) then we should note that in the
README.txt
The number of "lucene" jars included in the release is also odd -- they
are embedded in the solr.war obviously, but not included anywhere else.
so people wanting to do something like use apache-solr-core-3.1.0.jar to
embed solr in their app still need to get the lucene jars from a distinct
release ... except that there does seem to be 3 lucene jars included in
./contrib/analysis-extras/lucene-libs (i suspect this was a mistake in an
intentional exclusion of those jars)
###
Moving on to lucene-3.1.0-src.tar.gz
Similar README.txt problem as solr ... jars, wars, and javadocs are
mentioned that don't exist in the src release, and there is not verbage
mentioning that these files won't exist until you build them.
Similar question about CHANGES.txt still listing changes in old releases
... thought we wnated to prune those down.
In general, i'm wondering if there is really any value anymore in having
distinct src artifacts for "lucene-java" and solr ... my gut inclination
is that while it certainly makes sense to have distinct binary releases
(people using just the core library really don't care about hte baggage of
a fully solr release) for the source releases, we should just have a
single package containing a full checkout of hte top level build dir, so
people get all the source (and all the top level dev-tools) ... assuming
we have a top level README.txt that is about building *all* of the source,
then that would also help deal with some of hte other issues about the
individual solr/README.txt and lucene/README.txt files refering ot things
that aren't there until you build them. ... but agian, i assume there
was some discussion about this that i missed, and there is agood reason
for maintaining distinct src packages.
###
Lastly: lucene-3.1.0.tar.gz
Similar to my question about the solr binary release: aren't we required
to include source in all binary releases? in this case there aren't even
any maven jars in this packaging (which makes me doublely question the
maven jars in the solr package) which means we don't even have the source
in jar form.
if exclusion of the src is intentional here, then we should probably
exclude the BUILD.txt file as well.
one other thing that jumps out at me is that the README.txt refers to
contrib/demo/luceneweb.war but even in this release that doesn't exist,
just contrib/demo/lucene-demo-3.1.0.jar (and looking back at the source
release i think that's just blatently out of date -- it looks like the war
form of hte demo was completley removed from the build.xml)
this got me looking at docs/demo.html to see if it still refers to the
demo war (it doesn't) where i notice the "Setting your CLASSPATH"
instructions suggest that lucene-demo-{version}.jar will be found in the
main direcotry along with lucene-core-{version}.jar ... we should update
that to be contrib/demo/lucene-demo-{version}.jar
other then that -- things look good. jars all seem to be there, manifests
look good, and the demo runs correctly
####
What next from here?
I'd like to try and help fix some of this, but except for some of hte
really trivial stuff (version numbers in solr CHANGES.txt and tutorial;
demo war refs in lucene README) i'm not really sure how to proceed --
it really depends on the overall strategy of the "src" only packages (was
there a thread or jira on this? ... i really can't find any discussion
about it) to decide what to do about the README.txt files and other
documentation.
