NumberParser and exponent
by Henrik Nergaard March 29, 2017

March 29, 2017

Hi, Apperently the number parser cannot parse '2E+2' correctly, is this a bug or a feature. ('2E+2' asNumber = '2e2' asNumber) Is there any reason to why parsing numbers with uppercase exponent letter is not allowed? (see NumberParser >> #exponentLetters) The parser has a method named #allowPlusSignInExponent sending self >> #allowPlusSign which just returns false. Is there any reason for not allowing the pluss sign / having it as true instead? (I guess it should at least be an ivar so it can be configured?). Best regards, Henrik

Crashes on snapshot with the new compactor
by Eliot Miranda March 29, 2017

March 29, 2017

Hi All, a number of people are being affected by crashes on snapshotting the image, the worst possible time for a crash. There is a bug in the new compactor that unfortunately bites when saving. The compactor is invoked as part of a full garbage collect after the garbage collector has feed unreachable objects. Normally the new compactor makes only a single pass through the heap, which may not move all the objects that are possible to move. (The amount of objects that can be moved in a single pass is limited by available free space.) But on snapshot the compactor makes as may passes as are necessary to slide all movable objects down as far as possible. Unfortunately there is a bug in this second pass. Fixing this bug is now my priority. I have an example image from Esteban Lorenzano to test. I am asking anyone else that can provide an image that reliably crashes when trying to save it to make the image and changes available to me for testing if possible. In the mean time one may be able to work around the problem by doing a full garbage collect before snapshot. This should do a GC with a single compaction pass which should not fail, and then make it much more likely that the GC during snapshot will do a single compaction pass, since fewer objects should be mobile after the single pass compaction in the explicit GC. To do this in Pharo I would put a full gc here: SessionManager>>snapshot: save andQuit: quit | isImageStarting snapshotResult | ChangesLog default logSnapshot: save andQuit: quit. >> SmalltalkImage current primitiveGarbageCollect. self currentSession stop: quit. "Image not usable from here until the session is restarted!" ... In Squeak I would put a full GC here: snapshot: save andQuit: quit withExitCode: exitCode embedded: embeddedFlag "Mark the changes file and close all files as part of #processShutdownList. If save is true, save the current state of this Smalltalk in the image file. If quit is true, then exit to the outer OS shell. If exitCode is not nil, then use it as exit code. The latter part of this method runs when resuming a previously saved image. This resume logic checks for a document file to process when starting up." | resuming msg | Object flushDependents. Object flushEvents. ... Smalltalk processShutDownList: quit. >> SmalltalkImage current primitiveGarbageCollect. Cursor write show. save ifTrue: [resuming := embeddedFlag ifTrue: [self snapshotEmbeddedPrimitive] ifFalse: [self snapshotPrimitive]] "<-- PC frozen here on image file" ifFalse: [resuming := false]. I do apologise for the bug. I hope it will be fixed within a few days. _,,,^..^,,,_ best, Eliot

Missing refresh after method definition
by Stephane Ducasse March 28, 2017

March 28, 2017

Hi I often defined method and let the system guess and propose the addition to new instance variables and (they are red) but once I created the instance variables they should not be red anymore. Now nautilus does not refresh the pane and I end up having a warning about a non defined instance which is not one. Did you see this glitch? Stef

from time to time I get a class definition instead of a method
by Stephane Ducasse March 28, 2017

March 28, 2017

Hi guys from time to time while coding I get a class definition instead of a method. may be because I do not select protocols and be nice with the system. But I did not change the way I'm aggressively eduting code. I have the impression that we broke something inside nautilus Stef

ZnCharacterEncoderTests>>#testByteEncoderFromUrl mystery
by Sven Van Caekenberghe March 28, 2017

March 28, 2017

So it seems that ZnCharacterEncoderTests>>#testByteEncoderFromUrl started failing on the CI infrastructure but it passes fine for normal users and used to behave well in the past. It gets a file from the internet and does some stuff with it, very simple. Any ideas ? Sven
