Unable to read source file
« on: July 20, 2018, 10:52:15 am »
Hello there,

I just installed Code::Blocks on OpenSuse Leap 42.3 for Windows Subsystem (Windows 10 installed -> OpenSuse Sub).
I'm using wxWidgets version 3.0.4 nostl.
When I try to open an existing project I get the following error in the terminal:

Quote
NativeParser::DoFullParsing(): AddProjectDefinedMacros failed!
NativeParser::DoFullParsing(): Adding cpp/c files to batch-parser
NativeParser::DoFullParsing(): Added 1 source file(s) for project 'test' to batch-parser...

SystemHeadersThread: Total number of paths: 8
Final encoding detected: Unicode 8 bit (UTF-8) (ID: 43)
Encoding conversion has failed (buffer is empty)!
Something seriously went wrong while converting file content to wxString!

The Project is called "test" and has one source file: main.c. In Code::Blocks main.c only shows an empty file.
I can write and save but closing and opening a file makes the content disappear.
I used cat /path/to/project/main.c, and it displays everything I have written so far.

What language do you use? What encoding is the file? Does it also happen if you save it as utf-8 file?

file: main.c: text/plain; charset=us-ascii
Language: C/C++
I can save anything i write, but trying to re-open or read a file causes the above error and only shows an empty file

What version of codeblocks are you using? Do you see the assert dialog?

I assume there may be a problem with access rights to files.

Read this https://www.computerhope.com/unix/uchmod.htm after

Run in console where are main.c and where are files C::B IDE files:
Code: [Select]
ls -l
and post result here

does i  happen with any text file or only with files you created with codeblocks?
what if you use some other encoding then utf8?
does the same problem arises with the windows exe of codeblocks on the same system, same file?

are the layout and project settings saved and restored correctly?
what if you rename the c file to txt file?
do you use some color scheme?
are you sure the file is displayed as empty, or is the text simply white on white? does the cursor move?

   Any, regardless of how the file was created.

   I tried Windows-1252 and default, no changes.

   No, the windows version can open any file without issue.

   I'm sorry, I don't know how to determine that.

   No changes.

   No, everything is set to default. (Didn't change anything yet)

   The file is empty -> pics: OpenSuse, Windows 10 (win10)

Could the problem be the BOM at the start of the UTF8 file?

   I'm sorry, I don't know how to determine that.
Edit the Project->Build options
close the project reopen it and look if the changes are there...


i am out of ideas.... The file encoding seems to be working, but the file reading is the problem... But it can read the XML documents, because otherwise you would not be able to open the project so file access is not the problem...
I have looked into the code and you fail in the
Code: [Select]
bool EncodingDetector::DetectEncoding(const wxByte* buffer, size_t size, bool convert_to_wxstring)function...
I am not quite sure what path the code goes...
Code: [Select]
if (cfgMgr->ReadInt(_T("/default_encoding/use_option"), 0) == 1)is false, because you are not getting
Quote
Warning: bypassing C::B's auto-detection!
so you go the mozilla detection route. There the first entry is
Code: [Select]
if (!buffer)
            return false;
so if buffer is a 0 pointer you will never continue, so the pointer is valid...

But later it fails in
Code: [Select]
bool EncodingDetector::ConvertToWxString(const wxByte* buffer, size_t size)with
Code: [Select]
if (!buffer || size == 0)so there is really something wrong here... More error logging would help. But in the end only debugging can solve this...

After looking future in the code i found this in
sdk\encodingdetector.cpp:137
Code: [Select]

bool EncodingDetector::DetectEncoding(const wxString& filename, bool convert_to_wxstring)
{
[....]
   size_t readBytes = file.Read((void*)buffer, size);
    bool result = false;
    if (readBytes > 0)
        result = DetectEncoding(buffer, size, convert_to_wxstring);
Shouldn't this be
Code: [Select]

   size_t readBytes = file.Read((void*)buffer, size);
    bool result = false;
    if (readBytes > 0)
        result = DetectEncoding(buffer, readBytes , convert_to_wxstring);
?

Anyway this does not explain why later the size is 0....

Run htop or top and find codeblocks in process list and create screenshot. Show which user is running codeblocks and path from where is running.

And look at the right to the folder /tmp in root directory.

ls -l /tmp
ls -l /where is codeblocks app

Try run codeblocks for root using sudo

https://en.opensuse.org/SDB:Administer_with_sudo

after run with sudo you can see in top process codeblocks running for root (not luiZiffer)

Ask bluehazzard mentioned the reason for the problem could be found only by making a debug and using a debugger.
My guess is that it is a combination of a cb and wx issue.
So you need to build both with debug information and do the stepping. :(

If you ask this question then there is a lot work ahead of you. We can not do anything because we do not have the problem, and also i have not the possibility to use windows with the linux subsystem... If you are motivated enough i will try to guide you trough the steps. Be aware this is A LOT WORK/Time, but you will also learn a lot!

I just installed Code::Blocks on OpenSuse Leap 42.3 for Windows Subsystem (Windows 10 installed -> OpenSuse Sub).
I'm using wxWidgets version 3.0.4 nostl.
First i would like to know how you installed all this... Compiled by yourself? Installed from repo?

Thank you all for helping, I managed to fix the issue. I removed everything and reinstalled wxWidgets this time with the version 2.8.12 and codeblocks from the subversion repo. And somehow it works now.
Thank you @BlueHazzard for being willing to invest so much time, sadly i don't have enough myself. (If you still want to know, I installed 3.0.4 via Opensuse download website, added the rpm, then zypper and yast; I got codeblocks from a tar file, installed it via /bootstrap, /configure, etc..
And I will probably sometime in the future work on my knowledge regarding linux).
@omlk it wasn't solved, it had the same issue.

Now it would be easy to help us ;)

1) Open the CodeBlocks_wx30-unix.cbp file
2) It probably will ask you about the global variable "cb_release_type" enter
Code: [Select]
-g in the base field...
3) If it did not ask about the "cb_release_type" global variable, then Settings->global variables..->Current variable->New->Name: cb_release_type->ok
3.1) proceed with step 2
4) Build->Rebuild. This will need some time...
5) Hit Alt+G and type "encodingdetector" and double click or enter the encodingdetector.cpp file
6) Git Ctrl+g and type "149" to go to line 149
7) Set a breakpoint to this line by klicking between the line number and line text until a red circle appears, or hit F5
8) Start the debugger with Debug->Start
9) A new Codeblocks (we will call it debugee from now on) will open. Open your faulty file in the debugee.
10) The codeblocks window from where you are debugging will pop up, or blink or whatever... It will display the line 149 with a yellow arrow
11) Open the watches with Debugg->Debugging windows->Watches
12) Now go back to the code and make a right click on "buffer"->Add watch
13) Now go back to the code and make a right click on "size"->Add watch
14) Now this two values will appear in the watches dialog. Please tell us the values
15) Now step trought the program and tell us what functions are called:
15.1) To step one line hit the F7 key. The yellow arrow will make a step. Please note us the path the yellow arrow makes until the end of this function....
16) If the yellow arrow is at line 247 you can abort the debugee by hiting the red button in the toolbars

In that case, they need to have wxWidgets 3.0 installed on the PC.

10) The codeblocks window from where you are debugging will pop up, or blink or whatever... It will display the line 149 with a yellow arrow
Sorry, but this doesn't happen. As in, it successfully builds and that's it. What do you mean with faulty file? (I assume you meant the project and clicked on test.cbp)
Also, I completely removed the former codeblocks to install the repo version, I still have the .tar.gz file though.

No, it doesn't. The window opened, i selected test.cbp, and it closed, that's it.
I'm using the WLS so I'm using Xming on windows. (Don't know if this is relevant)

Your debugger settings are wrong.
You've set gcc as debugger instead of the correct gdb.
(most of the time I ignore long posts)

You can fix this in Settings->Debugger->Default on the left side->Executable path-> point it to gdb

I figured out the reason.
I created two files. test has 616 bytes, which cannot be opened in c::b in Ubuntu (Windows subsystem), with the error described in the original post, and test2 has 617 bytes, which can be opened:
https://imgur.com/a/3eZv6kG
Notice the size on disk, test is 0 byte, while test2 is 4KB.
This happens if the file is so small that its contents and the filesystem bookkeeping fit in 1KB. To save disk space, NTFS keeps small files "resident", storing their contents right in the file record, so no cluster has to be allocated for it.
reference: https://superuser.com/questions/1030800/how-can-a-files-size-on-disk-be-0-bytes-when-theres-data-in-it

TL;DR: If the file is too small (<617B), it may not be found by c::b.

Anyone know how to report the bug?
