Epicea

Hi all,

I would like to ask your opinion on Epicea, a tool that logs code
changes you do in your Pharo image. In a few words, its comparable to
the traditional "change sorter + .changes file mechanism ":

- it's serializable to/from a textual format file, that you can file
in/file out.
- the changes are logged to file immediately after they are announced
by the system.
- there is a UI where you can browse/manipulate the changes

The main difference is that in .changes/.cs, the history is modelled
as a sequence of chunks (DoIt's or just strings) that the tools *try*
to parse in order to know what happened. In Epicea, the history
elements are reified. For example, EpMethodModification models a
method that was modified from an old state to a new state, so it
answers to #oldMethod with a RGMethod holding the source code and the
protocol as it was before the code change.

I have been working on it during last time, it has been used by
several users, and it's quite stable. The project is in a "work in
progress" state, but I think it can be useful.

To install it in latest Pharo4:

Gofer new
    smalltalkhubUser: #MartinDias project: #Epicea;
    configuration;
    load.

MultiByteFileStream #converter - what does it do?

 

Hi there,

I am still working my way through MultiByteFileStream tests, and have come across the messages #converter and #converter: .  I would like to be able to test these - could someone explain briefly how the converters are used in this class?

Many thanks,

Sheridan

14615 Change in Delay semantics when high priority timer event loop stopped


I'm looking for some community feedback on Case 14615. When the high 
priority Delay timer event loop is stopped, there are two basic choices:

1. Delays wait indefinitely, since their delaySemaphore is never 
signaled, and so for example, the UI locks up.

2. Delays are ignored, proceeding immediately. This would let the UI 
continue working, give you a chance to restart the timer event loop, or 
change the DelayScheduler algorithm on-the-fly (e.g. mutex, semaphore, 
spinlock).

The system currently does (1.).  This is impeding integration of
Case 14252 to change Delays from millisecond to microsecond clock, since 
as a Preload the Delay timer event loop is stopped to load the slice.

I'd like to change it to (2.), which can be done in a single line.

Your thoughts ?

showing all icons

Is there a way to show all available ThemeIcons? I think that I've seen something some time ago (maybe in Glamour?), but I can't find it now... so maybe just my imagination?

Yes, that is true.

I has been going fast for quite a while, but it seems to be accelerating.

OK! Let's see if we can unravel the mystery of the rest!

No I don't find any signal of activity for this (nor in the Windows task
manager to see if the Pharo.exe became zombie.

I'm running Windows 8.1, Pharo3.0 Latest update: #30862.

The path for Pharo is C:\Users\csrabak\Fuba\H\Pharo3.0 and this is its content:

FT2Plugin.dll

Pharo3.0.image

As you can see above, the path has no blanks in its entire pathname.

I cannot arrive at this point... is there any VM or image switch that could help in this case?

Trigger Jenkins from Fogbugz?

It seems the CI monkey polls Fogbugz for cases at 15 minute intervals. 
Now if I'm troubleshooting a submitted slice, it would be nice to have a 
quicker turnaround. Any chance Fogbugz could be configured for a "case 
resolved" event to trigger a the CI to poll Fogbugz...

http://www.fogcreek.com/fogbugz/docs/70/topics/plugins/URLTrigger.html

https://github.com/jenkinsci/fogbugz-plugin/blob/master/URLTRIGGER.rst

https://www.fogcreek.com/fogbugz/plugins/plugin.aspx?ixPlugin=5

This would help speed some development cases.

Hi,

there seems to be some weird clipping issue in Spec's tabs.
The issue is in Pharo4; Pharo3 works fine.
