Are we able to run pharo images in a read only environment?
Hi - I am trying to run a pharo image in lambda (as an experiment) - however I get an error from Pharo about not being able to write to the changes file? As I am just evaluating some code - Iâm not really coding, so donât need a changes file - is there a command line option to not require it? Also, am I running pharo the most efficient way - Iâm using eval on the command line and referencing a class with a class method - but is this the best way? Thanks, Tim "errorMessage": "Command failed: ./pharo Pharo.image eval \"Lambda processJSON: '{\"key3\":\"value3\",\"key2\":\"value2\",\"key1\":\"value1\"}'\"\n'Pharo cannot write to the changes file named /var/task/Pharo.changes.\n\nPlease check that you have write permission for this file.\n\nYou won''t be able to save this image correctly until you fix this.'\n\u001b[31mError: Can't find the requested origin\n\u001b[0mUnixResolver(PlatformResolver)>>cantFindOriginError\n[ self cantFindOriginError ] in UnixResolver(PlatformResolver)>>directoryFromEnvVariableNamed: in Block: [ self cantFindOriginError ]\nUnixResolver(PlatformResolver)>>directoryFromEnvVariableNamed:or:\nUnixResolver(PlatformResolver)>>directoryFromEnvVariableNamed:\nUnixResolver>>home\n[ self home / '.config' ] in UnixResolver>>preferences in Block: [ self home / '.config' ]\nUnixResolver(PlatformResolver)>>directoryFromEnvVariableNamed:or:\nUnixResolver>>preferences\nUnixResolver(FileSystemResolver)>>resolve:\nSystemResolver(FileSystemResolver)>>unknownOrigin:\nSystemResolver(FileSystemResolver)>>resolve:\nInteractiveResolver>>unknownOrigin:\n[ self unknownOrigin: origin ] in InteractiveResolver>>resolve: in Block: [ self unknownOrigin: origin ]\nIdentityDictionary(Dictionary)>>at:ifAbsent:\nInteractiveResolver>>resolve:\nFileLocator>>resolve\nFileLocator(AbstractFileReference)>>exists\nGlobalIdentifierStonPersistence(GlobalIdentifierPersistence)>>shouldCallPreviousPersistence\nGlobalIdentifierStonPersistence(GlobalIdentifierPersistence)>>ensure:\nGlobalIdentifier>>ensure\nGlobalIdentifier class>>initializeUniqueInstance\nGlobalIdentifier class>>uniqueInstance\nSystemSettingsPersistence class>>resumeSystemSettings\n[ :persistence | persistence resumeSystemSettings ] in PharoCommandLineHandler>>runPreferences in Block: [ :persistence | persistence resumeSystemSettings ...etc...\nBlockClosure>>cull:\nSystemDictionary(Dictionary)>>at:ifPresent:\nSmalltalkImage>>at:ifPresent:\nPharoCommandLineHandler>>runPreferences\nPharoCommandLineHandler>>activate\nPharoCommandLineHandler class(CommandLineHandler class)>>activateWith:\n\u001b[0m", "errorType": "Error", "stackTrace": [ "'Pharo cannot write to the changes file named /var/task/Pharo.changes.", "", "Please check that you have write permission for this file.", "", "You won''t be able to save this image correctly until you fix this.'", "\u001b[31mError: Can't find the requested origin", "\u001b[0mUnixResolver(PlatformResolver)>>cantFindOriginError", "[ self cantFindOriginError ] in UnixResolver(PlatformResolver)>>directoryFromEnvVariableNamed: in Block: [ self cantFindOriginError ]", "UnixResolver(PlatformResolver)>>directoryFromEnvVariableNamed:or:", "UnixResolver(PlatformResolver)>>directoryFromEnvVariableNamed:", "UnixResolver>>home", "[ self home / '.config' ] in UnixResolver>>preferences in Block: [ self home / '.config' ]", "UnixResolver(PlatformResolver)>>directoryFromEnvVariableNamed:or:", "UnixResolver>>preferences", "UnixResolver(FileSystemResolver)>>resolve:", "SystemResolver(FileSystemResolver)>>unknownOrigin:", "SystemResolver(FileSystemResolver)>>resolve:", "InteractiveResolver>>unknownOrigin:", "[ self unknownOrigin: origin ] in InteractiveResolver>>resolve: in Block: [ self unknownOrigin: origin ]", "IdentityDictionary(Dictionary)>>at:ifAbsent:", "InteractiveResolver>>resolve:", "FileLocator>>resolve", "FileLocator(AbstractFileReference)>>exists", "GlobalIdentifierStonPersistence(GlobalIdentifierPersistence)>>shouldCallPreviousPersistence", "GlobalIdentifierStonPersistence(GlobalIdentifierPersistence)>>ensure:", "GlobalIdentifier>>ensure", "GlobalIdentifier class>>initializeUniqueInstance", "GlobalIdentifier class>>uniqueInstance", "SystemSettingsPersistence class>>resumeSystemSettings", "[ :persistence | persistence resumeSystemSettings ] in PharoCommandLineHandler>>runPreferences in Block: [ :persistence | persistence resumeSystemSettings ...etc...", "BlockClosure>>cull:", "SystemDictionary(Dictionary)>>at:ifPresent:", "SmalltalkImage>>at:ifPresent:", "PharoCommandLineHandler>>runPreferences", "PharoCommandLineHandler>>activate", "PharoCommandLineHandler class(CommandLineHandler class)>>activateWith:", "\u001b[0m", "ChildProcess.exithandler (child_process.js:204:12)", "emitTwo (events.js:106:13)", "ChildProcess.emit (events.js:191:7)", "maybeClose (internal/child_process.js:886:16)", "Process.ChildProcess._handle.onexit (internal/child_process.js:226:5)" ] }

AFAIU the purpose of AWS Lambda is to have "fire and forget" kind of functions, mainly stateless consumers of single purpose functions, with "infinite" transparent scalability. Like for processing ads clicks/impressions, receiving data from lots of mobile/IoT devices, etc. Regards, Esteban A. Maringolo

Sven - was this a 32bit image from get.pharo.org/70-minimal?
It came from a link Pavel sent me for debugging purposes, he is the expert, I don't know if there are both 32 and 64 bit versions (or even if there is much difference, if any).

Hi - I am trying to run a pharo image in lambda (as an experiment) - however I get an error from Pharo about not being able to write to the changes file?
As I am just evaluating some code - Iâm not really coding, so donât need a changes file - is there a command line option to not require it?
Also, am I running pharo the most efficient way - Iâm using eval on the command line and referencing a class with a class method - but is this the best way?
Thanks,
Tim

Yes, there should (optionally) be some log with timing info explaining which startup actions are executed and how long each takes. Maybe the log could just be kept in memory in the image.

Hi Sven, I'm curious how you are running your image. I am following this tutorial - https://aws.amazon.com/blogs/compute/scripting-languages-for-aws-lambda-runn... And am running pharo like the GO example by exec'ing via node js. My aim was to write an Alexa service in pharo vs nodejs like I have been doing. I was assuming I can call pharo via the eval option and stringify the Jaon Alexa Paramus and return a result via Stdout... well in theory, and the work to make pharo play better in wider ecosystem. It should work, and it seems you did make it work... but how? Like you, I am wondering when I run it on an ec2 instance (non lambda), why it takes so long to load? It feels like it can be faster?

Hi Sven, I'm curious how you are running your image.
I am following this tutorial - https://aws.amazon.com/blogs/compute/scripting-languages-for-aws-lambda-runn... <https://aws.amazon.com/blogs/compute/scripting-languages-for-aws-lambda-runn...>
And am running pharo like the GO example by exec'ing via node js.
My aim was to write an Alexa service in pharo vs nodejs like I have been doing.
I was assuming I can call pharo via the eval option and stringify the Jaon Alexa Paramus and return a result via Stdout... well in theory, and the work to make pharo play better in wider ecosystem.
It should work, and it seems you did make it work... but how?
Like you, I am wondering when I run it on an ec2 instance (non lambda), why it takes so long to load? It feels like it can be faster?

Hi - I am trying to run a pharo image in lambda (as an experiment) - however I get an error from Pharo about not being able to write to the changes file?
As I am just evaluating some code - Iâm not really coding, so donât need a changes file - is there a command line option to not require it?
That is really strange, it should just work (it does for me using the zero config scripts).
I would try to use absolute (resolved) paths as much as possible.
Also, am I running pharo the most efficient way - Iâm using eval on the command line and referencing a class with a class method - but is this the best way?
Yes, that is ok.
Thanks,
Tim

The error about saving the changes file comes from the fact that at startup, Pharo tries to open Pharo.changes in read and write mode, which is impossible if you are in a read-only environment. I am working on deploying Pharo in read-only, and it's one of the main problems that shows up during my tests. -- View this message in context: http://forum.world.st/Are-we-able-to-run-pharo-images-in-a-read-only-environ...

Thanks Sven - I was going to search for that as I recall it being talked about. I will give it a go and report back on results with Lambda. Iâm not sure how sensitive it is to image sizes and trying to open that file - so it will be interesting. Tim

It looks like a simple lambda execution takes about 2700 to 2900ms
I guess it is more affordable to pay for 3 secs than for a whole minute with 95% idle time. However it seems to be a lot of time for the case of lambda use cases. Esteban A. Maringolo
