Dear all,
I've a question about the bug reports listed in bugs.eclipse.org.
Bugzilla's report "bug-count over eclipse version" shows that the number
of bugs for minor releases is much lower than the bug count for major
releases (e.g. version 3.0.2 compared to 3.0). Is a bug that is reported
for version 3.0, also a bug in version 3.0.2? Do bugs that are reported in
e.g. version 3.1 also belong to version 3.1.2?
Furthermore, I'm search for statistics about how many users are there for
different versions of Eclipse. Are there any such figures?
I apologies if this is the wrong place for posting this question. However,
if this is the wrong news-group maybe someone can give me a pointer where
I can get an answer to my question.
Thanks in advance.
Best regards,
Martin

Bugs have whatever version they were reported against. That's not an
automated feature, it just depends on the person reporting the bug. If you
report a bug, you say what version you're reporting it on. Probably a lot
of the time, people misreport, e.g. they report "3.2" when really they're
using 3.2.2.
Then, eventually the bug gets fixed and the committer sets the "target"
field to the earliest version they expect to see the fix in - for instance,
3.4M5. Again, this is a human process, with some ambiguity (e.g., maybe
they end up not tagging the files in time and the fix doesn't actually get
into the specified version, or maybe it gets in even sooner, or maybe it
gets back-ported to a maintenance release of an earlier version).
If a bug is reported on 3.1, it might also exist in 3.1.1 and 3.1.2, or it
might not - there is no way to know except by trying it yourself. The odds
are that the bug exists on every version between when it was reported and
when it was fixed ("target"), but that is not guaranteed.
Also, sometimes a temporary workaround will be committed to a maintenance
release, but the bug will be left open until a better fix can be committed
to a later version.

Thanks for clarifying this. If I understood that explanation correctly
this implies for me, that reports generated by bugs.eclipse.org may be
misinterpreted.
For example, consider the report [1] which shows the number of
open/unconfirmed/assigned bugs for every Eclipse version. Using the
above explanation, this means for me, that this graph should be a
stair-case like function instead of having a saw tooth like shape.
Am I right?
Thanks in advance.
Best regards
Martin

I must be misunderstanding the question, but if it's a bug in version X,
it remains a bug until the release in which it's fixed. I.e., if it's
reported in 3.1, and fixed in 3.3.2, then it's also a bug in 3.1.1,
3.1.2, 3.2, 3.2.1, 3.2.2, 3.3, and 3.3.1. I don't think there's any way
to capture this in bugzilla reports. Also, the version number field in
bugzilla is not very reliable - many users don't actually set this field
when they report bugs, and it assumes some default value.

It is interesting/dismaying to me that we see periodic questions of this
nature around here. Basically, someone wanting to data-mine Bugzilla. In
every case, it seems the person wanting to do so has overlooked the fact
that Bugzilla data is inherently unreliable (there is no QA of the data,
of course). It seems people really want to measure stuff that has no
meaningful measurement axis - I wonder if PhDs or $$$ are being given
for research that measures and analyzes inherently inaccurate and
unreliable data...
