Exception handling bug; NameLookupFailure>defaultAction
by tim Rowledge 03 Jan '19

03 Jan '19

I was taking a swing at fixing the FileBrowser bug caused by the non-existence of st.cs.uiuc.edu wherein we get a very annoying loop of notifiers and a hard time trying to get out of them. Looking around the related code suggests we really want to clean up a lot of methods to do with serverdirectory, ftpurl etc. The error handling bug is quite simple to trigger for you pleasure and amusement (I'm past being amused by it and have gone around enough times that I think I can no longer see the wood for the trees) NetNameResolver addressForName: 'st.cs.uiuc.edu' timeout: 10. should do it for you. The problem is that we get to NameLookupFailure>defaultAction (because there is no other handler), which uses a UI to ask if the user wants to try again (sigh; raising a UI from a system error...) and if the option to retry is picked then it sends #restart to the handlerContext - which is not set. So far as I can see handlerContext only gets set by sending #privHandlerContext: which is only done just *after* the code that we just ran to get into trouble. With no set handlerContext we're also in trouble if we want to #pass, #return: or even just query #isNested. If we use a 'deliberate' handler it works as one might hope [NetNameResolver addressForName: 'st.cs.uiuc.edu' timeout: 10] on: NameLookupFailure do:[:ex| ex pass]. So, maybe an edge case that got over-optimised? Like I said, my brain is now useless for this and it needs another set of eyes. tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Strange OpCodes: FSRA: Forms Skip and Run-Away

usable FTP site that we can reasonably include as an example?
by tim Rowledge 02 Jan '19

02 Jan '19

The long-gone st.cs.uiuc.edu site used to be our example of how to add a remote directory but... long-gone. Can we enable anonymous ftp access to a directory on squeak.org as a replacement? files.squeak.org might appear appropriate but seems to be locked to only http access right now. tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim To define recursion, we must first define recursion.

David T. Lewis uploaded a new version of Chronology-Core to project The Trunk: http://source.squeak.org/trunk/Chronology-Core-dtl.16.mcz ==================== Summary ==================== Name: Chronology-Core-dtl.16 Author: dtl Time: 30 December 2018, 4:35:23.83548 pm UUID: 0dcd076c-b568-4d2a-bbec-2c747ce32f23 Ancestors: Chronology-Core-cmm.15 Bootstrap UTCDateAndTime, step 1 of 5 Add LXDateAndTime and LXTimeStamp as alternative implementations of DateAndTime an TimeStamp. DateAndTime uses instance variables 'seconds offset jdn nanos' and calculates its magnitude based on those varables in conjunction with the local TimeZone, The LXDateAndTime variation uses instance variables 'utcMicroseconds localOffsetSeconds'. It represents time magnitude as elapsed microseconds since the Posix epoch, with localOffsetSeconds representing local offset from UTC. The magnitude is used for comparison and duration calculations, and the local offset is used for displaying this magnitude in the context of a local time zone. The implementation ignores leap seconds, which are adjustments made to maintain earth rotational clock time in synchronization with elapsed seconds. LXDateAndTime class>>now uses #primitiveUtcWithOffset to obtain current time in UTC microseconds with current local offset in seconds. The primitive provides an atomic query for UTC time and local offset as measured by the OS platform. If primitiveUtcWithOffset is not available, the traditional implementation is used, which relies on a primitive for microseconds in the local time zone and derives UTC based on the TimeZone setting. Tests are provided to verify equivalence of the LXDateAndTime and DateAndTime hierarchies. LXDateAndTimeConversionTest tests conversion to and from LXDateAndTime. LXDateAndTimeTest, LXDateAndTimeEpochTest, and LXDateAndTimeLeapTest are variations on their corresponding DateAndTime tests. These tests are placed in the Kernel package because they are temporary tests that will be removed when LXDateAndTime replaces DateAndTime in a later update. =============== Diff against Chronology-Core-cmm.15 =============== Item was added: + ----- Method: Date class>>readYearMonthDayFrom: (in category 'squeak protocol') ----- + readYearMonthDayFrom: aStream + "Read Date information from the stream in any of the forms: + <day> <month> <year> (15 April 1982; 15-APR-82; 15.4.82; 15APR82) + <month> <day> <year> (April 15, 1982; 4/15/82) + <year>-<month>-<day> (1982-04-15) (ISO8601)" + | day month year parsedNumber prefix monthIndex | + aStream peek = $- + ifTrue: [prefix := -1] + ifFalse: [prefix := 1]. + [aStream peek isAlphaNumeric] + whileFalse: [aStream skip: 1]. + aStream peek isDigit + ifTrue: [ + parsedNumber := (Integer readFrom: aStream) * prefix. + (parsedNumber < 0 or: [parsedNumber > 31]) + ifTrue: [year := parsedNumber]]. + [aStream peek isAlphaNumeric] + whileFalse: [aStream skip: 1]. + aStream peek isLetter + ifTrue: ["MM-DD-YY or DD-MM-YY or YY-MM-DD" + month := WriteStream on: (String new: 10). + [aStream peek isLetter] + whileTrue: [month nextPut: aStream next]. + month := month contents. + [aStream peek isAlphaNumeric] + whileFalse: [aStream skip: 1]. + parsedNumber isNil + ifTrue: ["MM DD YY" + day := Integer readFrom: aStream] + ifFalse: [ + year isNil + ifTrue: ["DD MM YY" + day := parsedNumber]]] + ifFalse: ["MM-DD-YY or DD-MM-YY or YY-MM-DD" + year isNil + ifTrue: ["MM-DD-YY or DD-MM-YY" + parsedNumber > 12 + ifTrue: ["DD-MM-YY" + day := parsedNumber. + monthIndex := Integer readFrom: aStream. + "month := Month nameOfMonth: (Integer readFrom: aStream)"] + ifFalse: ["MM-DD-YY" + monthIndex := parsedNumber. + "month := Month nameOfMonth: parsedNumber." + day := Integer readFrom: aStream]] + ifFalse: ["YY-MM-DD" + monthIndex := Integer readFrom: aStream. + "month := Month nameOfMonth: (Integer readFrom: aStream)"]]. + [aStream peek isAlphaNumeric] + whileFalse: [aStream skip: 1]. + year isNil + ifTrue: [year := Integer readFrom: aStream] + ifFalse: [day := Integer readFrom: aStream]. + (year < 100 and: [year >= 0]) + ifTrue: [ + year < 69 + ifTrue: [ year := 2000 + year] + ifFalse: [year := 1900 + year]]. + + monthIndex ifNil: [monthIndex := Month indexOfMonth: month]. + ^ { year . monthIndex . day } + !
