overholt	open Valgrind bugs: https://bugs.eclipse.org/bugs/buglist.cgi?query_format=advanced&short_desc_type=allwordssubstr&short_desc=&classification=Technology&product=Linux+Tools&component=Valgrind&long_desc_type=allwordssubstr&long_desc=&bug_file_loc_type=allwordssubstr&bug_file_loc=&status_whiteboard_type=allwordssubstr&status_whiteboard=&keywords_type=allwords&keywords=&bug_status=UNCONFIRMED&bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED&emailtype1=substring&email1=&emailtype2=substring&email2=&bugidtype=include&bug_id=&votes=&chfieldfrom=&chfieldto=Now&chfieldvalue=&cmdtype=doit&order=Reuse+same+sort+as+last+time&field0-0-0=noop&type0-0-0=noop&value0-0-0=	03:02
overholt	project plan: http://www.eclipse.org/projects/project-plan.php?projectid=technology.linux-distros	03:02
overholt	we have very little in the way of text in the project plan	03:02
overholt	and I need to fix up the bug queries to make them reflect items planned	03:03
overholt	let's start with you, ksebasti	03:03
overholt	what do you plan to do for OProfile?	03:03
overholt	we should collect all items (even long-term ones) in bugzilla	03:03
overholt	then prioritize per milestone/release	03:04
overholt	so let's file some	03:04
ebaron	sounds good	03:04
overholt	and look at the open ones	03:04
ksebasti	well after the user guide im doing now (which i think is looking pretty good :D http://wiki.eclipse.org/Linux_Tools_Project/OProfile/User_Guide)	03:04
overholt	:)	03:04
overholt	and that's bug ~272039	03:04
KOS-MOS	Bug 272039 - https://bugs.eclipse.org/bugs/show_bug.cgi?id=272039 - Linux Tools / OProfile / unspecified - All / All - NEW / normal / - Assignee: ksebasti@redhat.com - Write OProfile plugin user documentation	03:04
ksebasti	i plan to start on ~265794	03:04
KOS-MOS	Bug 265794 - https://bugs.eclipse.org/bugs/show_bug.cgi?id=265794 - Linux Tools / OProfile / unspecified - PC / Linux - NEW / enhancement / - Assignee: ksebasti@redhat.com - OProfile: Start/Stop profiling manually or after given duration	03:04
overholt	okay	03:04
overholt	jjohnstn: akurtakov_: others who may be interested: we'd love to hear your thoughts on these things	03:05
overholt	crazy ideas welcome :)	03:05
ksebasti	because i can see it poking in many areas, and would make the plugin much more useful	03:05
overholt	ok	03:05
ksebasti	also add some tests to the launch plugin..	03:05
overholt	okay	03:05
overholt	we can file these bugs afterwards	03:06
overholt	let's just talk here	03:06
ksebasti	they were mysteriously absent :)	03:06
overholt	heh	03:06
overholt	what about the hot spot colourization?	03:06
ksebasti	indeed that could probably make it too	03:06
overholt	okay	03:06
ksebasti	because theres already some code in a branch that didnt make it for 0.2	03:07
ksebasti	but id rather have it at a lower priority than the start/stop feature	03:07
overholt	so for 0.3 OProfile we have: colourize hot spots, write documentation, and make the profiling manually controllable	03:07
overholt	so the latter two for sure	03:07
ksebasti	because its a nicety rather than a functionality thing	03:07
overholt	the first one maybe	03:07
overholt	okay with me	03:07
overholt	anyone else have an opinion?	03:07
ksebasti	oh the documentation should be done reasonably soon.. its already been a good chunk of days :p	03:07
overholt	ok	03:08
ebaron	looks good to me	03:08
jjohnstn	overholt: unfortunately I haven't played with the OProfile plugin to have any meaningful comments....I could review the user doc though	03:08
overholt	jjohnstn: that's cool. what about general profiling features you'd liek to see?	03:08
ksebasti	also ~273116 but thats just a small bug which im pretty sure is a 1-2 line fix	03:08
KOS-MOS	Bug 273116 - https://bugs.eclipse.org/bugs/show_bug.cgi?id=273116 - Linux Tools / OProfile / unspecified - PC / Linux - NEW / normal / - Assignee: ksebasti@redhat.com - vmlinux text box not repopulated	03:08
overholt	with gprof coming in, we'll have to think about how to make it as general as possible	03:08
overholt	ksebasti: ok, we'll leave that targetted at 0.3	03:09
overholt	anything else for OProfile in 0.3? Early July is the target release date for 0.3.	03:09
ksebasti	later in the cycle when policy kit 1 is out perhaps poke into ~265646	03:10
KOS-MOS	Bug 265646 - https://bugs.eclipse.org/bugs/show_bug.cgi?id=265646 - Linux Tools / OProfile / unspecified - PC / Linux - NEW / normal / - Assignee: ksebasti@redhat.com - Find better way to do non-root opcontrol invocation across distros	03:10
ksebasti	and at some point i'd like to clean up (in the most general sense :-) the opxml code for future maintainers	03:11
ksebasti	and see how much of it could perhaps be used from oprofile xml output	03:11
ksebasti	and otherwise poke upstream	03:11
ksebasti	whoo 0.3 is gonna be fun ;)	03:11
overholt	:)	03:11
overholt	so realistically we're looking at ~272039, ~273116, and ~265646	03:12
KOS-MOS	Bug 265646 - https://bugs.eclipse.org/bugs/show_bug.cgi?id=265646 - Linux Tools / OProfile / unspecified - PC / Linux - NEW / normal / - Assignee: ksebasti@redhat.com - Find better way to do non-root opcontrol invocation across distros	03:12
overholt	documentation, small vmlinux fix, and start/top daemon	03:12
rcjsuen	overholt: Punctuation bug still in place. ~272039 ~273116	03:12
KOS-MOS	Bug 272039 - https://bugs.eclipse.org/bugs/show_bug.cgi?id=272039 - Linux Tools / OProfile / unspecified - All / All - NEW / normal / - Assignee: ksebasti@redhat.com - Write OProfile plugin user documentation	03:12
KOS-MOS	Bug 273116 - https://bugs.eclipse.org/bugs/show_bug.cgi?id=273116 - Linux Tools / OProfile / unspecified - PC / Linux - NEW / normal / - Assignee: ksebasti@redhat.com - vmlinux text box not repopulated	03:12
overholt	rcjsuen: thanks	03:13
ksebasti	thats definitely doable	03:13
overholt	ksebasti: when the gprof contribution is cleared by legal we'll have to look at integrating that	03:13
overholt	okay, great	03:13
overholt	unless anyone else has thoughts about OProfile, we can move on to Valgrind	03:13
ksebasti	im inclined to add ~249181 because i expect the first 2 to not take very long	03:13
KOS-MOS	Bug 249181 - https://bugs.eclipse.org/bugs/show_bug.cgi?id=249181 - Linux Tools / OProfile / unspecified - PC / Linux - NEW / enhancement / - Assignee: ksebasti@redhat.com - Colourize hot spots in code	03:13
overholt	ksebasti: let's try to get it in but not put the milestone on. and let's leave it until the other things are done	03:14
ksebasti	overholt, righto	03:14
overholt	as usual, if people have bugs or RFEs or whatever, file away	03:14
overholt	thanks, ksebasti	03:14
overholt	ebaron: let's move on to Valgrind	03:14
overholt	ebaron: https://bugs.eclipse.org/bugs/buglist.cgi?query_format=advanced&short_desc_type=allwordssubstr&short_desc=&classification=Technology&product=Linux+Tools&component=Valgrind&long_desc_type=allwordssubstr&long_desc=&bug_file_loc_type=allwordssubstr&bug_file_loc=&status_whiteboard_type=allwordssubstr&status_whiteboard=&keywords_type=allwords&keywords=&bug_status=UNCONFIRMED&bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED&emailtype1=substring&email1=&emailtype2=substring&email2=&bugidtype=include&bug_id=&votes=&chfieldfrom=&chfieldto=Now&chfieldvalue=&cmdtype=doit&order=Reuse+same+sort+as+last+time&field0-0-0=noop&type0-0-0=noop&value0-0-0=	03:15
ebaron	overholt, thanks	03:15
ebaron	overholt, ~272198 should be resolved now	03:15
overholt	ebaron: all of those except "Investigate CDT Debug integration" have a target of 0.3.	03:15
KOS-MOS	Bug 272198 - https://bugs.eclipse.org/bugs/show_bug.cgi?id=272198 - Linux Tools / Valgrind / unspecified - All / All - NEW / normal / - Assignee: ebaron@redhat.com - Binary for test project does not always get built	03:15
overholt	ebaron: sweet!	03:15
overholt	ebaron: is cachegrind mostly done?	03:16
ebaron	overholt, yes	03:16
overholt	ebaron: what's up next?	03:16
ebaron	overholt, i was looking into birt charting, but that's more of a callgrind feature	03:16
ebaron	for call graphs and such	03:16
overholt	ok	03:16
ebaron	overholt, so long term, we'll have callgrind and helgrind support	03:16
overholt	okay	03:17
overholt	could one of them get into 0.3?	03:17
ebaron	overholt, i feel there are more pressing things to take care of	03:17
ebaron	overholt, ~272035	03:17
KOS-MOS	Bug 272035 - https://bugs.eclipse.org/bugs/show_bug.cgi?id=272035 - Linux Tools / Valgrind / unspecified - All / All - NEW / normal / - Assignee: ebaron@redhat.com - Guard against segfaults of inferior program	03:17
overholt	ebaron: okay	03:17
ebaron	overholt, this issue brought the limitations of valgrind's xml output to my attention	03:17
overholt	ebaron: alright	03:18
ebaron	i took a look at how other valgrind GUIs handle errors of this kind	03:18
overholt	yeah, that'd be interesting	03:18
overholt	so that + documentation	03:18
overholt	anything new in Valgrind 3.4.0 that we need to support?	03:18
ebaron	valgrind actually does have good signal handling, but this does not get reported with XML output	03:18
overholt	ah	03:18
ebaron	overholt, just a few new options	03:19
overholt	could that make 0.3? or is it a non-issue?	03:19
ebaron	overholt, i think moving away from xml output would be beneficial	03:19
overholt	ok	03:19
overholt	will it be as parseable	03:19
overholt	?	03:19
ebaron	overholt, yeah 3.4.0 options for sure can make it in, i've already implemented the code for version checking	03:20
overholt	sweet	03:20
ebaron	overholt, it is parseable	03:20
overholt	alright	03:20
ebaron	alleyoop is one example of a GUI that doesn't use the xml output	03:20
overholt	okay. I guess we should do some smoke testing with galileo stuff for 0.3, too	03:21
ebaron	valkyrie, the "official" GUI for valgrind does use xml, but doesn't report segfaults or other kinds of errors	03:21
overholt	ksebasti: that goes for you, too. we're running builds against galileo deps but doing some smoke tests would be good.	03:21
overholt	ebaron: ok	03:21
overholt	so we can target 0.4 for callgrind or helgrind (whichever comes first)?	03:21
ebaron	overholt, sure	03:21
ebaron	overholt, callgrind would come first	03:22
overholt	and 0.3 for Valgrind can kind of be some further robustification	03:22
overholt	+ docs + Valgrind 3.4.0 support	03:22
overholt	+ the fix for ~272198	03:22
KOS-MOS	Bug 272198 - https://bugs.eclipse.org/bugs/show_bug.cgi?id=272198 - Linux Tools / Valgrind / unspecified - All / All - NEW / normal / - Assignee: ebaron@redhat.com - Binary for test project does not always get built	03:22
overholt	that works for me	03:22
overholt	then 0.3's work is predictable and you will hopefully have time for 0.4-targeted features	03:22
ebaron	overholt, i think it's important since most people use memcheck, i want to ensure it works perfectly	03:22
overholt	agreed	03:23
overholt	I'm going to guess no one else have any opinions	03:23
jjohnstn	I don't	03:23
overholt	okay	03:23
overholt	s/have/has	03:23
overholt	I'll post this log somewhere and send the link to the mailing list	03:24
overholt	people may come out of the woodwork with bugs then	03:24
overholt	I'm sure we'll have bugs filed once 0.2 is out, too	03:24
***ksebasti thinks ebaron should add a remix feature to his plugin ;)		03:24
overholt	a remix feature?	03:24
ksebasti	virtual turntables and all!	03:24
ksebasti	</joke>	03:24
overholt	ah	03:24
overholt	for sure!	03:25
ebaron	:D	03:25
overholt	well, we're only 30 minutes into our hour. we could discuss some other sub-projects	03:25
overholt	jjohnstn: we should file some bugs for your work re-writing the autotools builder	03:25
jjohnstn	overholt: ok	03:25
overholt	akurtakov_: for 0.3 we'll try to ship eclipse-build in some form?	03:25
overholt	jjohnstn: any plans for ChangeLog or libhover in 0.3?	03:25
overholt	pmuldoon: I don't know if you're around, but Anithra has been approved as a committer and will likely start working directly in SVN soon	03:26
akurtakov_	overholt: do we require it to produce a working eclipse for the release	03:26
overholt	pmuldoon: we should look at integrating your editor with the rest of the SystemTapGUI stuff	03:26
overholt	akurtakov_: I wonder if that should be the demarcation point where we release it for the first time?	03:27
jjohnstn	overholt: I would like to push libhover C++ and newlib for 0.3...for changelog I would like to take a look at an annoying CTRL+ALT+P bug	03:27
overholt	jjohnstn: okay, sounds good	03:27
akurtakov_	overholt: well, before this point we actually have nothing :)	03:27
overholt	akurtakov_: do you anticipate that happening in the next 8 weeks?	03:27
akurtakov_	overholt: at least a partially working sdk yes	03:28
overholt	akurtakov_: okay, well let's aim for that	03:28
akurtakov_	overholt: i mean builds and starts but don't know what happens after that	03:28
akurtakov_	:)	03:28
overholt	I'll file bugs for all of this stuff	03:28
overholt	akurtakov_: sure :)	03:28
overholt	akurtakov_: any big plans for .spec editor?	03:28
overholt	people asked for ability to build RPMs when I presented at EclipseCon	03:29
overholt	we should ensure we have bugs filed so people can hop on if they're interested	03:29
overholt	I'll do a big triage	03:29
akurtakov_	overholt: using rpmbuild?	03:29
overholt	akurtakov_: yeah	03:29
overholt	on another distro-related note, I'd had a bit of time to look at running the SDK tests against an installed set of packages	03:29
akurtakov_	overholt: i should take a look at the old plugins whether there is smth about building	03:30
overholt	I'd love to see if we get similar results on another distro -- preferably non-RPM -- but that'll take some coercion I expect :)	03:30
overholt	akurtakov_: yeah, we should see if we can use any of that code	03:30
overholt	akurtakov_: perhaps target 0.4 with some rudimentary RPM building	03:30
overholt	not 0.3	03:30
overholt	if anyone notices, I'm being conservative with estimates here	03:30
overholt	I want our project to be predictable as much as possible	03:31
overholt	hopefully that will get us some more contributors	03:31
overholt	or at the very least adopters	03:31
overholt	the Ericsson guys are going to start work on their tracing stuff soon, I expect	03:31
overholt	they were talking about it at EclipseCon	03:32
akurtakov_	overholt: i still want to get a form based editor but eclipse-build is taking my time	03:32
jjohnstn	overholt: was there ever a feature opened to make the rpm spec editor a RCP application?	03:32
overholt	akurtakov_: yeah, a form-based editor would be cool	03:32
overholt	jjohnstn: no, but that' s a neat idea	03:32
overholt	I don't think the non-RPM-based distros are ready for something like stubby yet, but it would be neat. maybe after akurtakov_ & co. have eclipse-build out there, more distros will pick it up	03:33
overholt	then they'll be at the stage of packaging other plugins	03:33
overholt	I'm going to write a little bit of "getting started" text for people not familiar with Eclipse plugin installation	03:33
overholt	oh, and the gprof contribution is undergoing legal review	03:34
overholt	but that'll hopefully be finished soon	03:34
overholt	then Xavier & co. can work in SVN	03:34
overholt	maybe that can make 0.3, actually	03:35
akurtakov_	exherbo packaging file is quite similar in structure to spec file	03:35
overholt	I played around with it	03:35
overholt	akurtakov_: I'm not familiar with exherbo	03:35
akurtakov_	so stubby would fit for them nicely	03:35
overholt	that's good	03:35
overholt	the gprof plugin as it stands opens up gprof output files	03:35
overholt	I'd love to see a standard way of using various profiling "backends"	03:35
overholt	ksebasti: does post-processing analysis make sense for OProfile?	03:35
ksebasti	what sort of post processing?	03:36
overholt	ksebasti: like saving the output in a file or something and then opening it up with an Eclipse view	03:36
overholt	I guess I meant post-execution analysis	03:36
overholt	I guess that's what we do now	03:36
ksebasti	the sample files are generated by oprofile and already there	03:37
overholt	I guess gprof doesn't do that	03:37
overholt	we'll have to see where things overlap and where they differ	03:37
overholt	I don't really have anything else to talk about	03:37
overholt	our 0.2 release is scheduled for review on May 6th	03:38
overholt	the slides are done and so's the N&N thanks to everyone	03:38
overholt	our builds are now producing p2 repositories	03:38
overholt	updates-nightly gets updated automatically with these	03:38
overholt	you may notice there's no site.xml anymore	03:38
overholt	that's because p2 repositories use content.jar (which is basically just a zip of content.xml)	03:39
overholt	oh, and we're down to 0 warnings	03:39
jjohnstn	cool	03:39
overholt	thanks for the work there, jjohnstn	03:39
jjohnstn	np	03:39
overholt	Hudson on build.eclipse.org is accessible to all	03:39
overholt	you can use your committer username/password to log in	03:39
overholt	I think I set everyone to have the permission to start builds	03:39
overholt	they happen automatically every 6 hours	03:40
overholt	i think that's all I have to say	03:40
overholt	anyone else?	03:40
jjohnstn	not me	03:40
overholt	ebaron: ksebasti: akurtakov_: you all okay for 0.3? I'll file bugs and send some follow-up mail	03:41
ksebasti	all good	03:41
overholt	giddy-up	03:41
ebaron	overholt, sounds good, i'm sure things will come up, but that's a good start	03:41
akurtakov_	yep, 0.3 for me is get eclipse-build as much as possible ready :)	03:41
ksebasti	overholt, im filing some bugs i just thought of though :)	03:41
overholt	ksebasti: thanks	03:41
overholt	akurtakov_: great, looking forward to it!	03:41
overholt	alright, thanks for taking the time to talk, everyone. next time I'll bill it as a "project meeting" so others may be more interested in attending :)	03:42
