If I remove Bitmap>>travelGuide (so that it inherits the default OrdinaryObjectTravelGuide instead of an empty travel guide) everything seems to work OK. This seems reasonable to me as a Bitmap's format is basically the same as an Array, which doesn't seem to require any special processing. I can add a simple test and submit a PR (in a few days time) if the change sounds OK to you.

Hi Alistair I will look when have a time. But you can try to write a test for bitmap serialization/materialization in TostSerializationTests (if I remember correctly the name). It will show if bitmap transport requires extra logic.

TelePharo / Seamless Bitmaps are all 0s

by Alistair Grant

Hi Denis, If I print: remotePharo evaluate: [ Array withAll: #(42 42 42) ] "==> #(42 42 42)" which is obviously correct, but: remotePharo evaluate: [ Bitmap withAll: #(42 42 42) ] gives me a bitmap with all zeroes (running it locally does the expected thing). I can see that the bitmap is being created correctly on the server, but by the time it gets back the values have been lost (all converted to 0s). If I change the Bitmap>>seamlessDefaultTransferStrategy for the Bitmap to #defaultByReference I can correctly access the values (just for debugging, by reference isn't practical for the real system). Any hints on where to look? Thanks again, Alistair

Re: [Pharo-users] Pharo download with wget

by Brainstorms

Which version of 'libcurl' do you have installed on your system? Due to some unfortunate history (involving naming), libcurl3 and libcurl4 cannot both reside on the same system. Try "locate libcurl.so". Does it show "libcurl.so.3" or "libcurl.so.4"? You may wish to upgrade to v4. Cheers, -Ted -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Hi Alistair. We forgot update telepharo baseline for fixed calypso version.

TelePharo breaks Calypso tabs

by Alistair Grant

Hi Dennis & Everyone, I'm just starting to play with TelePharo - it's really impressive. However loading either the server or client in Pharo 7 or Pharo 8 breaks Calypso so that I can no longer click on tabs to move between the Comment, Class Definition or methods. Is this a known issue? And is there a fix or workaround? In both Pharo 7 & 8 TelePharo was loaded with: Metacello new baseline: 'TelePharo'; repository: 'github://pharo-ide/TelePharo'; load: 'Server'. Metacello new baseline: 'TelePharo'; repository: 'github://pharo-ide/TelePharo'; load: 'Client'. in separate clean images downloaded 14 May 2019. OS: Ubuntu 16.04. Thanks! Alistair
