Oh, but it's just that (ex outer) will pass the exception to an upper level outer "Evaluate the enclosing exception action and return to here instead of signal if it resumes (see #resumeUnchecked:)." | prevOuterContext | self isResumable ifTrue: [ prevOuterContext := outerContext. outerContext := thisContext contextTag ]. self pass.

Re: [Pharo-project] Squeaksource mirror

by Carla F. Griggio

Hey guys! Just a question about the mirror *chileno*: is it possible that it copies just the last commited versions of each project? Because I don't see all the packages of one of my projects, just the packages that have been updated recently, with a couple of versions each. Cheers!

Re: [Pharo-project] Exception logging

It's more tricky than that... Try this one that works: |file| [ file := StandardFileStream fileNamed: 'loglog.txt'. file nextPutAll: 'Start'. [ file nextPutAll: (Compiler evaluate: '55 + 88 poipuiu') asString] on: Error do: [:ex | file nextPutAll: 'failed']. ] ensure: [file close].

Looks like Compiler might use it's own error handler?

Re: [Pharo-project] reading *exactly* n bytes from socket

by Schwab,Wilhelm K

Stef, It's not so much fixes for FFI as it is filling gaps. We need a full set of signed and unsigned word, dword, float and double arrays. Toward that end, I have a sloppy set that appears to work. I recently discovered that I will have to explicitly assign endianness due to changes in Pharo since 1.1. One thing that really disappoints me about my fixed type arrays is that they all ultimately use byte array to hold the data; I can't pass my DWORDArray to a ulong*; I have to specify void* to get it to work. Likewise with DOUBLEArray and double*. There are also alignment questions that need attention.

To make things easier, I sent #upToEnd to my SocketStream, expecting to get all the data (and then read the lines later).

When I know that the next packet of data from the server is going to be 10'000 bytes I want to ask the socket for exactly 10'000 bytes of data (I don't care how long it takes). However, the comments in the Socket class suggest that the buffer might not be filled entirely when the message answers.

Try "ex signalerContext errorReportOn: file" instead of "ex outer errorReportOn: file". Dave

Stef. If I understand correctly, ex outer will do ""Evaluate the enclosing exception action and return to here instead of signal if it resumes (see #resumeUnchecked:)."" So what you have to do is to use #signalerContext. Example: |file| [ file := StandardFileStream fileNamed: 'loglog.txt'. file nextPutAll: 'Start'. [ file nextPutAll: (Compiler evaluate: '55 + 88 adas') asString] on: Error do: [:ex | ex signalerContext errorReportOn: file ]. ] ensure: [file close].
