Unable to read source file

[LuiZiffer]

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:

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?

[LuiZiffer]

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

[oBFusCATed]

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

[BlueHazzard]

Language: C/C++

By language i mean your system language and encoding...
Settings in Settings->Editor->Encoding settings?

@oBFusCATed Is this what you meant? (Sry, I'm new to this)

Version: 17.12
Encoding when opening files: UTF-8
Encoding: as fallback encoding
Checked: If conversion fails using the settings above, try system locale settings

Language: (i hope this is what you want, as I wrote at the top, I'm new to this) OpenSuse - English, Windows - German
and encoding is UTF-8

Can you share a file that can not be opened ?

[LuiZiffer]

this is a simple hello world. The project can be opened, but when i open main.c the file appears empty.

[LuiZiffer]

After writing:

chmod 777 test/

I tried again with codeblocks but same result.

The requested output:

total 4
drwxrwxrwx 1 luiziffer users  512 Jul 20 09:33 bin
-rwxrwxrwx 1 luiziffer users  101 Jul 21 13:22 main.c
drwxrwxrwx 1 luiziffer users  512 Jul 20 09:33 obj

-rwxrwxrwx 1 luiziffer users  354 Jul 21 13:23 test.layout

[BlueHazzard]

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?

[BlueHazzard]

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?

[LuiZiffer]

does i  happen with any text file or only with files you created with codeblocks?

   Any, regardless of how the file was created.

what if you use some other encoding then utf8?

   I tried Windows-1252 and default, no changes.

does the same problem arises with the windows exe of codeblocks on the same system, same file?

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

are the layout and project settings saved and restored correctly?

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

what if you rename the c file to txt file?

   No changes.

do you use some color scheme?

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

are you sure the file is displayed as empty, or is the text simply white on white? does the cursor move?

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

[stahta01]

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

troubleshooting.txt contains the text "testing"

I tried:

vi troubleshooting.txt
:set nobomb
:wq

and,

sed -i $'1s/^\uFEFF//' troubleshooting.txt

without success

[BlueHazzard]

   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

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

 if (cfgMgr->ReadInt(_T("/default_encoding/use_option"), 0) == 1)

is false, because you are not getting

Warning: bypassing C::B's auto-detection!

so you go the mozilla detection route. There the first entry is

Code

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

bool EncodingDetector::ConvertToWxString(const wxByte* buffer, size_t size)

with

Code

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...
