A public expression of gratitude to issue posters

Posted by Eitan Suez Thu, 01 Feb 2007 21:37:00 GMT

Many of us take somewhat of a leap of faith when we decide to open-source our work. With respect to JMatter, I took some time to make that step, not knowing how things would pan out.

One thing that indeed happens and happens quickly, is that [once a tool for reporting issues was made available] approximately 100 issues were reported, perhaps 200 or more if you count informal issues reported through the mailing list, over perhaps a period of 3-4 months.

Today I took some time to look at and resolve some outstanding defects/issues.

One thing that is obviously wonderful about sharing this framework is that many of you have put this framework through paces and have uncovered bugs (many of which I've fixed by now, though nothing is perfect, and time is different when dealing with open source projects).

In retrospect, there's absolutely no way that I could have by myself uncovered some of these bugs. Some are exhibited in very special circumstances. I marvel at the nuances, and often tell myself: "wow, I would have never thought to try that."

So, I would like to say publicly: thank you, all of you who took the time to report these issues. I know I sometimes take time to get to them (but hey, it's not like I'm getting paid for this). This framework is improving as a consequence of your active participation.

One important note: when I asked the community what issue manager they recommended, a number of you recommended trac, which I installed. Since then, trac has gone through some upheaval as a consequence of having no provisions (at the time) to prevent spam. The bug database was trashed and it took quite some time to get it cleaned up, and back up and running. Consequently, I am requiring that users obtain an account if they're going to log issues (I hate to have to do this but I feel like I don't have a choice). For those of you who do not wish to go through so much, I would still very much appreciate to hear about your issues through the jmatter mailing list.

bugman said 2 days later:

Well here's another one for you -

Latest release 02/02 - clicking a save several times

b/ right click on "Commands" icon

[java] No specific baseType so go with complexeobject..

Wasn't this supposed to be fixed?

b/ right click on "EOCommands" icon

c/ Select "EOCommands" from dropdown - (what is the point of this?)

d/ "Full Path" is mandatory yet you cannot enter any value for it.

a/ Right click on "Log" from classbar

b/ Select new - enter some data

c/ Select save

d/ Clicking on "Edit" quick enough several times will give you hibernate exceptions.

not a bug but just been using Contacts demo application for less than 15mins with about 100 log items - java.exe is using up more than 120mb of memory.

Rather excessive considering it's such a trival application - cannot imagine this framework scaling to bigger applications with 100s of users!

b/ Save two schedules with overlapping times

c/ Calendar only shows a single schedule on that block.

OK, had enough of this release, finding other people's bugs is not fun and i've only used this thing for the past 2 hours.

Until the next release... I'm out of here!!!

bugman, i don't know whether you're on the mailing list or what your email address is. i've read through your comments and jotted down my thoughts on each. if your'e interested, we can start a dialog off this blog? it sounds like you're really hating this framework. perhaps you should consider a competing product?

sincerely, eitan

Have you considered incorporating Cayenne (http://cayenne.apache.org/) for persistence in your product.

It has the ability to 'remote' objects,your swing app communicates via xml with the persistence layer in the application server using the same API as if persisting directly to the database.

This may impact scalability of applications developed with jMatter
