Minutes from discussion at ApacheCon Core Europe 2015
A useful discussion was had at ApacheCon today; here are my notes:
Present - Nick Burch, Dominik Stadler, David North. Shane Curcuru (ASF
director) was around and chipped in some useful suggestions.
Some discussion of making it easier to run the tests in-Eclipse; people
keep tripping over the "POI.testdata.path must be set" error. Dominik
has a patch for this which tries to find test-data in the cwd - which
Just Works out of Eclipse. ACTION: Dominik commit the patch.
Some discussion of knowing which tests to run before committing;
difficult to just run them out of Eclipse as the build process has some
hard-coded data about expected failures. David also mentioned it's
difficult to tell which ant target(s) to run to replicate the Jenkins
build. ACTION: David to sort out descriptions in build.xml so ant -p
gives useful and complete information.
Nick suggested David should manage a 3.14 beta1 release, as an exercise
to prove the release process is fully documented. ACTION: David to
arrange this.
Some discussion of where our code lives: are we happy with SVN or should
we migrate to Git?
Nick - enough bridging and mirroring mechanisms that working in Git with
the current setup and pushing back to SVN should be fine. Dominik: some
concern that differences in IDs make it impossible to clone from e.g.
the Github mirror and them push back direct to SVN. Nick - we should
talk to infra team, they may have a solution to this. ACTION: Dominik
talk to infra about how to work best with SVN via Git.
Some discussion of time it takes to run the tests. Timed "ant test"
(note: avoids integration tests) on David's laptop (i7 with an SSD) at 1
minute 17 seconds, which is good enough for now.
TestSignatureInfo appears to fail without internet access. ACTION: David
find out why and fix it.
Discussed whether to switch the build to Gradle from Ant. It's the way
the rest of the world is going, but no immediate rush. Removing some
knowledge/logic from the build first would be good. All agreed Maven is
too heavy/not suitable for POI.
Discussion of desirable new features. David: wanting to round out
FormulaParser support in XSSF. In particular, cross-workbook references
in formulae. Nick: it's 90% there. A bunch of tests in HSSF can be
promoted to joint tests if it's completed in XSSF. ACTION: David to try
and finish this. Noted there is some complexity to be discussed, e.g.
what text does getFormula give back, is it what's stored, what the user
sees in Excel - these will differ for cross-wb formulas.
Discussed what version of Java we should require. Current 1.6 is likely
to be where we stay for a while: end-users tend to be very conservative.
Discussed https://bz.apache.org/bugzilla/show_bug.cgi?id=58466
ACTION David: try swapping his impl for the speed-up, original was a
community patch so may not be perfect
Nick proposed we should have an ooxml-schemas-1.2 JAR containing visio,
security & main, rather than three separate artefacts. But keep the
existing lightweight one too. All agreed this made sense. ACTION:
Someone to implement this.
Nick: How should we address nobody reading the website. e.g s/overflow
and mailing list users never read the FAQ. No immediate ideas. ACTION:
all think about it. ACTION David - check out the StackOverflow tag for POI
Nick: CSS for JavaDocs might deserve a tweak when the new Apache logo &
its font guidelines are out - coming soon.
Discussed website and use of ancient version of Apache Forrest, now
discontinued. Not a major issue as just committers work on it. ACTION:
David read up on the Apache CMS and how other projects do websites, but
no change in POI for now.
David: are we happy with bugzilla? General consensus: Yes. JIRA is
painful for sysadmins and none of those present had a good word to say
about it. Dominik: Private tags are handy to organise bugs. Nick: I can
create public keywords if requested.
Javen O'Neal - decent number of patches coming in, we should offer to
mentor him to become a committer, any volunteers? Nick: I have a
half-written e-mail suggesting it. David: happy to do the mentoring as
the most recent addition to the team. ACTION: Nick send e-mail, David
follow up if Javen is interested.
Discussed web of trust - David: if I am to do a release, do I need to
sign it with my PGP key? Nick: yes, are you in the Apache web of trust?
ACTION: David pass keyslip to Nick so Nick can sign David's PGP key.
ACTION: all to trawl the website for out-of-date content.
ACTION: David to focus on formula docs + compatibility matrix images
alongside his work in this area.

The test is fine, I had a dodgy http_proxy environment variable set on
my laptop. No change needed.

FYI, I did a quick research on Git-SVN, there is documentation for how
to use the Git-SVN bridge at
https://wiki.apache.org/general/GitAtApache, sharing this Git-Repo
further while keeping the SVN-link is unfortunatly not possible due to
the way git-svn works, i.e. you always rebase onto the latest from
SVN, so the local changes are always "rebased" onto the SVN-data and
thus "pushing" to other Git repositories is not possible.

Currently, the only way to push files onto the main apache.org web servers
is via svn. Previously you could do it via ssh/scp, but that was removed
for various reasons (see the infra and infra-dev archives for full details
if you care!). Today, the only way is to commit to a suitable bit of svn,
which the web servers watch and fetch

I was thinking we should treat documentation artifacts like build
artifacts: only version control the source, host the artifacts on a regular
file server.
Consider moving documentation build artifacts to non-version-controlled web
server.
