When analysing my code using valgrind (WSL) only output I get is list of problems found by it.
On the contrary in Clion documentation in valgrind section, images show that output (instruction pointer) can be directly interpreted into code line that has triggered it, as shown on the image below.
Whan do I need to do to toggle on this display mode or at least code line which triggered it, I am using CLion 2022.2.4?
I have already tried playing with diffrent flags but I was unable to toggle this view on.
This could be related to this bugzilla item (but not likely).
I tried it with CLion 2022.3.1 on FreeBSD 13.1. It was painful to get a project setup (clion didn't know where clangd or ninja were, and used a load of unrecognized clangd options).
After that no real problems.
I'm fairly certain none of the Valgrind devs uses WSL so the chances of this getting analyzed and fixed are very low.
I have two files main.raku and TestMod.rakumod in a directory C:\Users\suman.
TestMod.rakumod
unit module TestMod;
sub add($a, $b) is export {
$a + $b
}
main.raku
use lib $*PROGRAM.dirname;
use TestMod;
say add(8,9)
I want to call some functions in the TestMod module from main script file. When I run the script, I get this error
===SORRY!=== Error while compiling c:\Users\suman\main.raku
read from dirhandle failed: 123
at c:\Users\suman\main.raku:2

Rakudo specific information (installed from rakudo.org):
Welcome to Rakudo™ v2021.10.
Implementing the Raku® Programming Language v6.d.
Built on MoarVM version 2021.10.
This scenario however works in Linux. See MWE here.
Is it Windows specific issue/bug or am I missing something?
TL;DR A nanswer that might help you towards an answer.
What do I know?
Not a lot. I haven't used Windows for dev in years. I've not seen this error before.
I just decided to see what I could find. I found a couple things, read between the lines, and... ended up with this nanswer.
read from dirhandle failed: 123
A google for "read from dirhandle failed: 123" listed two matches for me.
One was this SO. I'm not sure that's especially helpful, though we are trying! 😊
The other match was:
githubmemoryhttps://githubmemory.com › ... · Translate this page ⋮
ohmycloud Profile - githubmemory
When I clicked it it did not include the error message I'd searched for.
But clicking the ⋮ showed an About this result popup, and a cache button at the bottom of that popup linked to an earlier version of the page that the search had matched. (This is a general trick to know about when a search result appears not to contain something you'd just searched for.)
And that page (which I can see with this URL; YMMV) contained this match:
when execute above script as Administrator, failed with read from dirhandle failed: 123
But it wasn't conclusive. Hmmm.
githubmemory.com is just a copy of GH. So I figured out it's a copy of this issue. And that is more conclusive. That is to say, the issue opener, ohmycloud, closes it with the conclusion:
It's actually a access deny error
Hmmm. Really?
Please consider investigating that angle, and perhaps editing your question to summarize your conclusions. But please read on first, because there are reasons to doubt it's an access error, as follows.
Windows System Error 123
My next research angle was determining exactly what the error code means.
I figured out the read from dirhandle failed: was from MoarVM, and that showed the error code was from GetLastError(), and I figured out that is from the Windows API, and I arrived at this reference entry:
The filename, directory name, or volume label syntax is incorrect.
Hmm. Why did ohmycloud talk about an access error?
We should probably try to investigate whether it is "just" invalid syntax rather than something else like an access error.
Please try the following, and consider whether it's worth pasting some of your results, at least one of them, into your question:
say $*PROGRAM.dirname.raku;
chdir $*PROGRAM.dirname;
say $*PROGRAM.dirname.IO.raku;
A last chance long odds dark horse?
While googling a tad more widely (dropping the 123) I found another match that might be of interest.
(It actually does have the same error, so I don't understand why it wasn't listed by the first google I tried, but whatever.)
It's this 2016 comment by nick cygx on the #moarvm channel
eventually dies with a SORRY: read from dirhandle failed: 123
This is also on Windows. One can tell that due to the error message but it's also confirmed later that same day on the IRC channel:
that "read from dirhandle failed" thing happens inside a windows ifdefed block
Afaict, cygx is saying they got the error message for the test case in the bug Class fails to smartmatch against role defined in module.
jnthn's response to this failure was:
That...makes no sense o.O
(Which is a pretty good summary of your SO.)
jnthn's said one other thing about cygx's error:
I've put off fixing up hyper/race for months already. :)
So, perhaps, or more lyrically as a last chance long shot dark horse, maybe there's some hyper/race related problem within MoarVM's guts that manifests on Windows in relation to module loading?
It would be helpful if you could try the "Minimal testcase" in the bug report. Do you get the 123 error?
If you do, then perhaps (even longer shot) it's worth someone trying to get in touch with cygx? Unfortunately the nick cygx last appeared on #moarvm in 2019. So I did a google for cygx raku. I found an 8 month old comment about Raku under that nick from 8 months ago. (Which I see I replied to ineptly. Sorry, cygx.)
#ugexe's comments
Their first comment is:
Pointing a use lib ... at [a directory containing] files your current user doesn't have access to isn't a good idea.
That suggests you would best make sure the directory you're pointing lib at is not a directory such as C:\Users\suman because, in the general case, that may include files your Rakudo compiler can't access. (Whether this is the case depends on your system setup and what files you have, but the simple solution is to make sure you only point lib at a directory dedicated to Raku code.)
Their last comment (below this answer) is a link to a gist with lines like this:
C:\Users\ugexe>raku --ll-exception -e "use lib '.'; use Test;"
read from dirhandle failed: 123
at SETTING::src/core.c/Rakudo/Internals.pm6:1345 (C:\Users\ugexe\.rakudobrew\moar-2021.10\install\share\perl6\runtime/CORE.c.setting.moarvm:next)
from SETTING::src/core.c/Rakudo/Internals.pm6:1374
.
.
.
I don't know how to interpret this gist, but I can see that their gist:
Shows them producing the same Windows System Error (123) with nothing but a use Test;;
Shows paths that, if passed to Windows, would presumably be syntactically invalid (C:\Users\ugexe\.rakudobrew\moar-2021.10\install\share\perl6\runtime/CORE.c.setting.moarvm:next). My guess is that they're not passed to Windows, but instead just constructed that way as part of displaying the error. But that is just a guess.
Moving .rakumod files to a separate folder within C:\Users\suman and importing with use lib "<separate folder>" from main script works.
In my case, when I move TestMod.rakumod to C:\Users\suman\rakulib and modify main script as follows:
use lib "rakulib";
use TestMod;
say add(8,9)
it works.
Also moving both files to Desktop also works.
But I find it weird! Because two python files similar to my question works fine without any issues even when both of them are in the folder C:\Users\suman.
file1.py
def add(a,b):
return a + b
file2.py
from file1 import add
print(add(8,9))
So I was expecting the same with raku. Unfortunately it's not the case.
read from dirhandle failed seems like access deny error as pointed by many rakoons. I am interested to know how can we fix this from within raku.
Acknowledgement: The ideas suggested by #jubilatious1 and #chenyf works. So I combine them here.
It's ok on my desktop:
raku .\main.raku
17
OS Version: Windows 11 professional(21H2)
Raku Version: 2021.10
Despite what I've said in my comment, it's entirely likely that dirname is behaving according to spec; only it's not in that spec to return a platform-specific name. So it would be interesting to investigate what $*PROGRAM.dirname returns. If it's a Linux-formatted path, that might be part of the problem.
This is raiph's answer points at: wrong syntax.
If that's the case, we need to get to the "right" syntax. That is why in the first version of this answer I pointed at using IO::Path::Win32 to create that syntax. Other option might be to simply put the directory name by hand. Finally, a bug can't be excluded.
It may be a problem with read permission: read from dirhandle failed
Move the module code into its own folder such as (for example) rakulib, one level down from your main (calling) script. Then call the module from the main script with:
Main Script: "Suman_main.p6":
use lib "rakulib";
use SumanTestMod;
say add(8,9);
Module Code: "SumanTestMod.pm6":
unit module SumanTestMod;
sub add ( $a, $b) is export {
$a + $b
}
[ Answer adapted from code found in Arne Sommer's "Beginning Raku" book, see: https://arnesom.github.io/ ]
I have a network path that contains hundred of thousands .wav files. When I do the following:
FileBuffer = Dir$("\\MEDIASERVER\*.wav", FileAttribute.Archive)
The line freezes forever. I have literally let it run a day, and it never returns with execution. I then decided to test the symptom with a dir command in DOS. Same symptom.
I then wondered if I would get the same symptom if I added a prefix to the search pattern narrowing my results. I did this in DOS:
DIR 0009*.wav
Worked like a charm. So, armed with this knowledge, I went back to my VB.NET project and applied a similar solution:
FileBuffer = Dir$("\\MEDIASERVER\0009*.wav", FileAttribute.Archive)
Doesn't get stuck, actually does the search. But I was surprised by the first result:
FileBuffer came back with the following value:
003925034541228334146804222014065036AM005020MIF.wav
This does not match the pattern I asked for. Can someone tell me what I am doing wrong? Is there a known bug with DIR$? Is there a way to achieve what I want without enumerating 100% of the files in the network share?
Additional Information if it's relevant:
Developement Machine: Windows 7 Pro, VS 2013 Pro
Network Server: Linux Centos 5.0 (I have the same issue with a network drive running Windows 7 Pro).
Thanks in advance.
Sorry for just posting the question, and already getting the answer. The question about whether or not it worked properly in DOS helped narrow my troubleshooting. I came across a couple of pages on the net stating that DIR will come back with unexpected results. They state that it's because of the 8.3 naming convention. I then decided to see if there was any other constraints I could add to my program. I changed the pattern to:
DIR \\MEDIASERVER\0009*MIF.wav
And now I am getting the expected results. This cannot be because of the 8.3 Naming convention though. It's something else, but at least I got this working.
Thanks for your time.
This actually originally generated from a problem I was having running SpookyJS, but managed to nail it down to a problem with the underlying CasperJS (and based on another stackoverflow question I was directed to, possibly even a PhantomJS problem).
We determined that the command CasperJS was failing on was:
casperjs C:\wwwroot\dra\node_modules\spooky\lib\bootstrap.js --spooky_lib=C:\wwwroot\dra\node_modules\spooky\lib\ --command=casperjs --port=8081 --transport=stdio
Which generates the following:
{"jsonrpc":"2.0","method":"emit","params":["error","CasperError: CasperJS couldn't find module C:\\wwwroot\\dra\\node_modules\\spooky\\lib\\bootstrap\\stdio-server",[{"file":"C:\\casperjs\\n1k0-casperjs-bc0da16\\batchbin\\..\\bin\\bootstrap.js","line":133,"function":"_require"},{"file":"C:\\wwwroot\\dra\\node_modules\\spooky\\lib\\bootstrap.js","line":34,"function":""}]]}
At first I thought the fact that it was generating double slashes was an issue, but I've since learned that that's simply the way it spits it out. It simply can't find the file. I've tried to reference the file a few different ways, but to no avail. And, yes, the file is most definitely there. It's looking for stdio-server.js which is exactly where it's looking for it. It's also not specific to this file. In the course of my testing, I commented out that line and it failed three lines later, in the same fashion, looking for a different file.
I'm using:
CasperJS 1.0.2
PhantomJS 1.9.0
I'm desperate to get this working (preferably today since I have to demo it to my boss), so if anyone has any input on this I'd be MOST appreciative!
Thank you.
You should be able to fix this by upgrading PhantomJS to 1.9.1
Here are links to the CasperJS issue and the PhantomJS issue regarding this problem.
Some months ago I installed Lazarus 0.9.28 + FPC 2.2.4 to work on a new project. Some time after it I ran into some bugs related with image loading on a TImage. After googling a bit I found some information pointing to the fact that the bugs I was facing were already solved in a later version of FPC (can't remember the link now).
So I decided to download and install a newer version. This was around January and the latest stable version was not released yet, so I choose to install the snapshot Lazarus 0.9.31-29128 + FPC 2.4.2-2011-01-20. I opened my project with the new IDE and compiled it.
Luckily the bugs I faced were gone, but I have run into an IDE (?) one. After the upgrade, when I am on the code tab of some of my forms I do not see the code formatted. Instead I only see plain text, like this:
But on some forms I see the code formatted correctly, like this:
Anyone has run into this before? If yes, could you solve it and how? Or can anyone tell me what the correct way to upgrade a Lazarus project between versions is?
It is more of a nuisance than a real problem but still I would like to solve it. Any help would be appreciated.
EDIT
I noticed that in the forms where the code shows correctly highlighted the LCLVersion in the .lfm file is 0.9.28.2, while in the forms where the code shows like plain text that property in the .lfm file is 0.9.31. Could have something to do with the problem? I tried changing the value but it did not change anything.
Thanks in advance and best regards
I don't know if this is actually causing your problem, but Lazarus keeps a set of settings in application local. ($user\AppData\Local\lazarus on my vista).
This config dir is not erased upon deinstallation, and the new installation will reuse this.
In case of strange problems, remove the config dir, and let the current installation generate a new one.
