Re: WebDav and CalDav in Pharo ?

by jonathan＠objectguild.com

Hi Udo, I hope you are well. Would like to hear more about the updates you mentioned back in November 2019 on your FileSystemNetwork library and WebDAV specifically. We are looking to work with WebDAV/CalDAV using your FileSystemNetwork library for a customer application. As a first step, we have migrated your SmalltalkHub project to a GitHub repo here:Â https://github.com/objectguild/FileSystemNetwork After some modifications to the code for Pharo 8, all unit tests are showing green (we're using a test server URL created usingÂ https://www.webdavserver.com) However, there seem to be some issues handling the actual (binary) file contents. I'm not familiar with the FileSystem classes and I'm having some trouble understanding the technical design, so I'm sure to have made mistakes. Are you willing (and able) to take a look and help out? Perhaps you can show me in the right direction :-) FYI, we have to work in Pharo 8 because of technical contraints. Hope to hear from you!

Re: ReStore and storing mixed dictionaries

by John Aspinall

Hi Offray, There isnât currently a formal way to do the automatic transformation you describe (it would be a nice enhancement though). What I have done in similar situations is to carry out the transformation in inst var accessors, e.g. userPictureURL ^userPictureURL ifNotNil: [ZnUrl fromString: userPictureURL] userPictureURL: aZnUrl userPictureURL := aZnUrl pathPrintString ânot sure if this is the correct conversion but you get the ideaâ You then define: #userPictureUrl as: String. This works because ReStore accesses instance variables directly via instVarAt:[put:], but obviously depends on your own code using accessors rather than direct references. Hope this helps.

Re: ReStore and storing mixed dictionaries

by Offray Vladimir Luna CÃ¡rdenas

Hi John, Thanks. With the improved error message I was able to pin the cause of error better. The issue was that I was declaring the user picture URL as a ZnURL instead of as a string in the reStoreDefinition, but I was not telling ReStore how to store ZnUrl objects. So I made the returning method to give me a string instead of a ZnUrl, which is kind of counterintuitive for the my model, but returned something that ReStore knew how to serialize. I wonder if there is a way, maybe using something like derived keys, to tell reStoreDefinition: execute this block instead of calling the current method to store the value in the database. So, the #profileImageUrl returns a ZnUrl object inside the image model, but is stored as a string in the database without adding more reStoreDefinition for particular objects (like a ZnUrl). Could be this possible in someway? Am I missing something? The objects storing is advancing now and hopefully we will have results soon to share, instead of troubleshooting (but we'll share both anyway ;-P).

Hi Konrad Sorry, but which version of Pharo are we talking about. I just tried with Pharo 10, which has no flatten method for arrays at all, somewhere along the version I believe the method was renamed to flattened. #(1 #(2 #(a b) 3) 4) flattened >>> #(1 2 #a #b 3 4) as one would expect. flatCollect: does not flatten the collection it is called on, but the result produced by the block #(1 3) flatCollect: [ :e | {e. e * 10} ] >>> #(1 10 3 30), and #(1 #(2 3 #(4 5)) 6) flatCollect: [ :e | {e. e * 10} ] >>> #(1 10 #(2 3 #(4 5)) #(20 30 #(40 50)) 6 60) I am not going to comment on naming of such core api methods - they tend to have a 40 year history of forgotten arguments and random âclean upsâ.

Intended behaviour of flatten and flatCollect:

by Konrad Hinsen

Hi everyone, I am getting surprising results trying to flatten nested arrays. So I read the docstrings. And now I understand even less how flatten and flatCollect are supposed to work. flatten says: "Recursively collect each non-collection element of the receiver and its descendant collections. Please note, this implementation assumes that strings are to be treated as objects rather than as collection." That suggests that #(1 2 3) flatten should yield #(1 2 3). But it raises an exception, trying to send do: to an integer. A quick look at the code shows that flatten is just flatCollect: [ :each | each ]. flatCollect: says: "Evaluate aBlock for each of the receiver's elements and answer the list of all resulting values flatten one level. Assumes that aBlock returns some kind of collection for each element. Equivalent to the lisp's mapcan" "Flatten one level" is different from flatten's "recursively". The assumption that aBlock returns a collection is also incompatible with what flatten is supposed to do (and explains my exception). I don't find the reference to a Lisp function very helpful. Assuming "Lisp" means "Common Lisp", this confirms the docstring of flatCollect:, this confirms the assumption of aBlock returning a collection, and that only one level of nesting is flattened. Since flatCollect does what it says, the problem seems to be in flatten. Either its docstring or its implementation are wrong. Or is it me misunderstanding something? Cheers, Konrad

Re: ReStore and storing mixed dictionaries

by John Aspinall

Hi Offray - could you try modifying SSWReStore>>createProxyForNewObject: as follows: ... table := self tableForClass: anObject class. "Add this ->â table isNil ifTrue: [ self error: 'cannot find table for ', anObject class name ]. id := table idDataField ifNotNil: [ :idDataField | idDataField accessor valueIn: anObject]. â¦ This should change the error message to show the class of object which doesnât have a valid table.

Re: ReStore and storing mixed dictionaries

Hi John, Effectively ReStore didn't was storing the table object for the Nitter class. But after following your advice, i'm now able to debug both the TwitterUser and the NitterUser and obtain the same result (which makes sense as the later is inherited from the former). I think that my error was related with the definition of the synchronized tables, as I was not includingÂ explicitly the NitterUser (as I thought it would suffice with the TwitterUser one). Now it looks like this: === ReStore connection: (SSWSQLite3Connection on: privateDatabase fullName); Â Â Â connect; Â Â Â addClasses: { Tweet. "TwitterUser." NitterUser }; Â Â Â synchronizeAllClasses. === Now I can get a non nil idDataField that has the same shape when #tableForClass: and "reStoreDefinition asTableIn: ReStore" are send to TwitterUser and NitterUser. Despite of that I still get the pre-commit error: "#idDataField was send to nil". Here is a screenshot of the trace of the error and the idDataFiled seems right (or at least equal to the same field inÂ the TwitterUser): https://i.imgur.com/F3UDC93.png For the moment, I'm planing to use an extra/temporal TwitterStoreHelper object that stores via ReStore/SQLite the objects I'm unable to store so far, but as dictionaries of key/value helper objects, where the value is just the STON serialization of the object (with the inconveniences of not being able to query it properly). For example, a 'profiles' dictionary in TwitterStoreHelper would have a Twitter/Nitter user id as a key and its Ston representation as a value.

Re: ReStore and storing mixed dictionaries

by John Aspinall

Hi Offray, Regarding the error, Iâm guessing that ReStore doesnât have a table object for your NitterUser class for some reason. Could you try: myReStore tableForClass: NitterUser â¦and check if this is returning nil? If so thereâs an issue with creating the table for the class; you could try stepping through NitterUser reStoreDefinition asTableIn: myReStore ...to get an idea of whatâs wrong. If this isnât the issue please let me know. Regarding the manual, Iâll send this to you by mail. Cheers.

Re: [ANN] Pharo 10 released!

by Norbert Hartl

Congratulations! Iâm happy that finally the image lost some of the deprecated things. Great work! I could migrate our product today to pharo10 in less than 90 minutes. While all the time went into docker, jenkins and all the infrastructure stuff. Only a single thing I needed to change because my code did not handle Deprecations. I hope we can keep the release cycle as short as this.

Re: ReStore and storing mixed dictionaries

by Offray Vladimir Luna CÃ¡rdenas

Thanks Jhon, it definitively helps. What I did was to extract some important metadata as slots of the Tweet object and made explicit the authorId, which allows me to trace tweets authorship: === Tweet>>class #reStoreDefinition ^ super reStoreDefinition Â Â Â defineAsID: #id; Â Â Â define: #text as: String; Â Â Â define: #created as: String; Â Â Â define: #authorId as: String; Â Â Â define: #timelines as: (Dictionary of: String -> String); yourself === Also I'm going to put in the radar the idea of storing STON strings for metadata residues. On a related matter, I'm still unable to store properly the NitterUser, which inherits from TwitterUserÂ into SQLite and always get a pre-commit error: "#idDataField was send to nil" when I ran "myNitterUser store". Here is my TwitterUser storing definition: === TwitterUser>>class #reStoreDefinition Â Â Â ^ super reStoreDefinition Â Â Â Â Â Â Â Â Â defineAsID: #id; Â Â Â Â Â Â Â Â Â define: #userName as: String; Â Â Â Â Â Â Â Â Â define: #profileImageUrl as: String; Â Â Â Â Â Â Â Â Â define: #profileBio as: String; Â Â Â Â Â Â Â Â Â "define: #createdAt as: String;" Â Â Â Â Â Â Â Â Â yourself. === What I'm missing? And more importantly: how can I debug the message, so I can asign the proper non nil object as receiver of #idDataField ? Finally (for now ;-) ), the ReStore manual has been and important learning resource. Are you the author? And if so, would you be so kind to upload the Word source code to the Documentation/ folder in the repository under a permissive license that allow at least some format changes? We would like to add some table of contents and translate it to other formats, as we have done before with other free/libre cultural works (see [1] [2]).

Re: [ANN] Pharo 10 released!

by Steffen MÃ¤rcker

Congratulations to the new release. That's quite an impressive amount of changes and cleanups. Will the stable version be available in the PharoLauncher soon? Cheers, Steffen Esteban Lorenzano schrieb am Dienstag, 5. April 2022 12:39:44 (+02:00): Dear Pharo users and dynamic language lovers: We have released Pharo version 10 ! Pharo is a pure object-oriented programming language and a powerful environment, focused on simplicity and immediate feedback. Pharo 10 was a short iteration where we focused mainly on stability and enhancement of the environment : Massive system cleanup gained speed removed dead code removed old/deprecated frameworks (Glamour, GTTools, Spec1) All Remaining tools written using the deprecated frameworks have been rewritten: Dependency Analyser, Critique Browser, and many other small utilities. Modularisation has made a leap, creating correct baselines (project descriptions) for many internal systems, making possible the work and deployment of minimal images. Removing support for the old Bytecode sets and embedded blocks simplified the compiler and language core. As a result, our image size has been reduced by 10% (from 66MB to 58MB) The VM has also improved in several areas: better async I/O support, socket handling, FFI ABI, Even being a short iteration, we have closed a massive amount of issues: around 600 issues and 700 pull requests. A more extended changelog can be found at https://github.com/pharo-project/pharo-changelogs/blob/master/Pharo100Chang…. While the technical improvements are significant, still the most impressive fact is that the new code that got in the main Pharo 10 image was contributed by more than 80 people. Pharo is more than code. It is an exciting project involving a great community.
