Relative paths #76

HexenZ · 2018-07-27T09:44:17Z

Hi, I'm having an issue with vscode-bash-debug, maybe it's just a matter of misconfiguration but I don't know were to go and I'll appreciate help. Having the following scripts:

#file1.sh
#!/bin/bash

echo 'hello'

. ./file2.sh

#file2.sh
#!/bin/bash

echo 'world'

The debugger isn't able to debug file2.sh. But changing '. ./file2.sh' to '/absolute/path/file2.sh' works fine.

launch.json:

{
"version": "0.2.0",
"configurations": [
{
"type": "bashdb",
"request": "launch",
"name": "Bash-Debug (hardcoded script name)",
"cwd": "${workspaceFolder}",
"program": "${workspaceFolder}/file1.sh",
"showDebugOutput": true,
"trace": true,
"args": []
}
]
}

The text was updated successfully, but these errors were encountered:

HexenZ · 2018-08-20T12:30:42Z

Any help please? Still looking for a solution

rogalmic · 2018-08-20T18:03:58Z

Sorry for late response:

why there is space between dots?
. ./file2.sh
try :
source ./file2.sh
or
source ../file2.sh
depending the file location

HexenZ · 2018-08-21T06:22:32Z

Hi, thanks for answering. I'm really new to bash and I'm a bit lost with it. Anyway, the first "." of . ./file2.sh is similar to source (I don't know the difference and source ./file2.sh doesn't works neither). And I cannot replace because I have to maintain bash scripts of thousands lines that are using that "." not the example itself.

The thing is that . ./file2.sh actually works but the debugger won't stop at break points leading me to dismiss the tool for working until the problem is solved.

rogalmic · 2018-08-21T06:47:46Z

You are correct, dot works as well...

Which version of bashdb/bash do you have? (I successfully tried on 4.4.0-94 and also build 91 + bash 4.4.19)

You could try installing newest bashdb:
#67

HexenZ · 2018-08-21T07:03:57Z

I'm using

bash: GNU bash, versión 4.4.19(1)-release (x86_64-pc-linux-gnu)
bashdb: bashdb, release 4.4-0.94

We're using the same or am I wrong?

rogalmic · 2018-08-21T10:33:48Z

Yes, we are using the same - this is interesting ...

Are you able to provide some snapshots + exact reproduction steps. Screen record would be ok as well. Can there be some issues with accessing the "sourced" file?

HexenZ · 2018-08-21T12:39:42Z

The steps are:

Click 'Debug' -> 'Start Debugging'
Press F5 (Continue)
The script finishes and the result is printed:

As I allready said it stops at the first breakpoint placed at a1.sh line 3 (echo hello) but it doesn't at the second a2.sh line 3 (echo world).

I suppose that if there were problems accesing the file it wouldn't work with absolute path neither, maybe I'm wrong with that.

rogalmic · 2018-08-21T14:14:16Z

OK, so the reason is now obvious. When setting breakpoint source path when debugging, it does not accept paths with spaces nor slashes "-".

I am talking "load" and "break" commands from http://bashdb.sourceforge.net/bashdb.html.

Unfortunately wrapping path in " or ' or ` does not seem to help when i change code of extension... Need to investigate more...

Please use path without "-" to verify this finding.

Just to keep as evidence, the failing call in different flavours:

Issue reported:
https://sourceforge.net/p/bashdb/bugs/54/

HexenZ · 2018-08-22T07:34:29Z

I've changed the path name from "/home/adrian/test-shell" to "/home/adrian/testshell" and still having the same issue, it stops at the first break point but ignores the second.

There must be something else.

rogalmic · 2018-08-22T09:40:11Z

Please attach debug console output, when launch.json configuration has :
"showDebugOutput": true,

HexenZ · 2018-08-22T11:32:04Z

This is the console output:

Hmm, this is weird. Bashdb actually stops, and "continue" is sent by debugger:

Breakpoint 3 hit (1 times).

It stopped at breakpoint 3.

Can you see callstack when debugger stops and console shows:

->0 in file ./a2.sh' at line 3 ?

HexenZ · 2018-08-23T06:30:11Z

Yes, I've noticed that bashdb actually stops at the breakpoint and it seems that vs-code sends a "continue" instruction even if I'm running the option "Debug step by step".

Here's the callstack output:

->0 in file ./a2.sh' at line 3 (Unknown origin:3) ##1 source("./a2.sh") called from file /home/adrian/testshell/a1.sh' at line 5 (/home/adrian/testshell/a1.sh:5)

I'm wondering... could it be an error with using $0 internally?

I got these vars at the watch list:

$PWD=/home/adrian/testshell
$0=/usr/bin/bashdb

rogalmic · 2018-08-23T08:13:22Z

I am a bit confused, since continue can only be sent by vscode to extension, there is no other path for that.

So it seems that vscode calls the extension's callback containing "continue" by itself, without any user action?

Are you using mouse to click the debugger buttons or "F5"/"F10"/"F11" ?

HexenZ · 2018-08-23T09:36:08Z

I'm using F5 most of the time or the "play like" arrow:

Anyway, every time I'm testing, I try every button or F* key.

rogalmic · 2018-08-23T12:38:45Z

What is the platform/system and VS code version?

I mean everything looks ok from debug session point of view, so we need to look for problem higher in stack...

HexenZ · 2018-08-24T06:49:22Z

SO: Ubuntu 18.04.1 LTS
VScode: 1.26.1

If you need any other info let me know :)

rogalmic · 2018-08-24T10:19:07Z

I installed Ubuntu on VM, i think i am able to reproduce the problem:

Notice that the uppermost element in callstack is grayed out, which means that relative path './a2.sh' is not working in linux. Seems that vscode working dir is different on linux. I will try to find a solution, possibly try to recover full path.

Some changes that might help (updated):
bash-debug-0.2.2.vsix.zip

Please test via "install from vsix" option and give feedback:

rogalmic · 2018-08-26T11:09:45Z

Preparing for release, here is test version:
https://github.com/rogalmic/vscode-bash-debug/releases/download/untagged-eccd51e3096d87c7b498/bash-debug-0.2.2.vsix

HexenZ · 2018-08-27T06:23:08Z

Some changes that might help (updated):
bash-debug-0.2.2.vsix.zip

Please test via "install from vsix" option and give feedback:

Sorry for the late reply, I've been on a trip and had no time. The vsix is working like a miracle!

Really... really thank you a lot for all your help and patience rogalmic.

rogalmic · 2018-08-27T09:16:55Z

I should thank you for patience :). Anyway, now the changes are released.

For spaces to work in script path, bashdb upgrade will be needed, after it's next release (those scripts can also be updated manually with code fixes in /usr/share/bashdb/* ).
