MikolajKonarski 3 Active Tickets 6 Threadscope fails to read partially written file ThreadScope ThreadScope 0.2.0 None enhancement maintainer assigned 2011-10-09T05:06:05Z+0100 2013-04-12T14:49:01Z+0100 "If ghc compiled program was launched with option to write eventlog and then was interrupted by Ctrl-C then eventlog file will be partially written. Actual behaviour: Threadscope fails to read such file complaining ""There was a problem loading the eventlog"", ""too few bytes. Failed reading at byte position 4194995"" Expecting behaviour: threadscope displays an info box saying that file was damaged and only first XXXX bytes (YYY seconds) was recovered then it should work as if this file was finalized properly." pacak 3 Active Tickets 8 malloc: pointer being freed was not allocated ThreadScope ThreadScope 0.2.0 None defect new 2011-11-18T16:37:00Z+0000 2012-05-18T13:11:51Z+0100 "{{{ $ threadscope threadscope(57833,0x7fff7e0b3960) malloc: *** error for object 0x101837168: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug Abort trap: 6 }}} This is with * a 64 bit machine * running MacOS X 10.7 * with GHC 7.2.1 * threadscope 0.2.0 * gtk-0.12.1" kowey 4 Active Tickets 10 include spark sizes etc in ch8 test ThreadScope None enhancement new 2011-11-25T10:05:49Z+0000 2011-11-29T13:31:40Z+0000 This would make a good wont-fix, but I was thinking it would be nice if people could play with all the bells and whistles on the sample trace. kowey 3 Active Tickets 15 not enough space in left panel for trace expansion? ThreadScope None defect new 2011-11-30T15:06:42Z+0000 2011-12-09T12:10:28Z+0000 "Another possible wont-fix: To my screen, the left panel is wide enough to display a list of traces with checkboxes. If you expand any of the trace tree and then collapse it again, the checkboxes disappear, presumably because they are too far to the right. Only reporting this because it can be easy to expand the traces by accident if you just click on them, for example, and the checkboxes disappearing can be a little bit confusing." kowey 4 Active Tickets 16 Redesign the UI using the general visual communication principles ThreadScope None enhancement new 2011-12-05T12:14:17Z+0000 2011-12-21T12:56:25Z+0000 Long term. Gather feedback, look at how easy it is to describe the UI in tutorials, discuss the various ideas from kowey's emails (Nov 20, 2011, Dec 1, 2011) and TODO (all IRC discussions are summarized there), study literature on visual communication (eg. Tufte), look at other libraries and programs. Then reshuffle the panes, draw the graphs differently, etc. to increase usability and make TS easier to learn.

MikolajKonarski 4 Active Tickets 19 Improve usability, especially the UI, based on use cases ThreadScope None enhancement new 2011-12-21T13:09:08Z+0000 2011-12-21T13:09:08Z+0000 This ticket is not about UI improved using the universal principles of visual communication, but about improvements based on down-to-earth analysis or imagining of use cases, user stories, (imagined) experiences with alternative UI mock-ups. etc. In other words, this is the broader question, with research, modelling => personas + scenarios => framework => detailed design. MikolajKonarski 4 Active Tickets 24 Print big times using large time units to avoid too long labels ThreadScope None defect new 2012-03-24T18:35:41Z+0000 2012-03-24T18:35:41Z+0000 "On very large eventlogs, the labels of histogram bars overwrite each other, because the numbers (spark lengths) grow too big. Extend and use the function that prints time in different units to handle large time values with large time units, that is kiloseconds and megaseconds, or perhaps minutes, hours, days, weeks, etc. " MikolajKonarski 3 Active Tickets 26 ThreadScope shows garbled characters when using Unicode characters in user event ThreadScope None defect new 2012-04-16T06:23:44Z+0100 2012-10-29T19:58:55Z+0000 "Debug.Trace.traceEventIO output Unicode characters by UTF-8 String. * http://www.haskell.org/ghc/docs/7.4.1/html/libraries/base-4.5.0.0/Debug-Trace.html#v:traceEventIO ""ghc-events show"" can show output Unicode characters' user event correctly. {{{ import Debug.Trace main = do traceEventIO ""テスト"" putStrLn ""test"" }}} {{{ $ ghc -O2 -threaded -eventlog Test.hs [1 of 1] Compiling Main ( Test.hs, Test.o ) Linking Test.exe ... $ .\Test.exe +RTS -l ""test"" $ ghc-events show Test.eventlog > test.log }}} {{{ Event Types: (snip) Events: (snip) 1531003: cap 0: running thread 3 1594090: cap 0: テスト 1805086: cap 0: stopping thread 3 (making a foreign call) (snip) }}} But ThreadScope can't show Unicode characters' user event correctly.

I have to either zoom in or zoom out to see the new graphs. killy9999 3 Active Tickets 29 Enhance handling of large eventlogs ThreadScope None enhancement new 2012-11-12T10:24:02Z+0000 2012-11-12T10:24:02Z+0000 When I enable detailed spark logging via -lf flag I end up with huge eventlog files (130MB). Attempting to load these into ThreadScope practically kills my OS - memory runs out, swapping begins and I am forced to kill TS (which takes some time before the OS actually responds and kills the process). This makes -lf flag useless for my program and I think this might not be uncommon situation. It would be good if TS supported some sort of lazy loading of big eventlogs, so users could at least view parts of the log. killy9999
