Summary0022893: Debugger: Run Parameters --all is not passed to program
DescriptionThe attached fpcunit test program needs to be run with --all or -a to run all tests.

I set a breakpoint here:
procedure Ttestexport1.Setup;

  TestDataset := TSDFDataset.Create(nil);
... which should always hit.

Specifying --all in Run/Run Parameters/Command line Parameters however does not have any effect and the breakpoint is not hit. Debugging does work because breakpoints elsewhere work.
Specifying -a or "--all" does work.
Steps To ReproduceSee above; run attached program.

Not tested with FPC trunk.
Additional InformationOccurs on
Laz 1.0/FPC 2.6.0 x86, Windows
Laz trunk/FPC 2.6.1 x86, Windows
Laz trunk/FPC trunk x86, Windows

The following program run from the IDE and --all as command line parameters does not print anything on windows:

var i:integer;
  for i:=1 to Paramcount do

Seems to be a windows gdb problem. Debug output shows:

<-exec-arguments --all>

gdb 7.3

Versions for the original bug report:
Laz 1.0/FPC 2.6.0 x86, Windows: GDB 7.4
Laz trunk/FPC 2.6.1 x86, Windows: GDB 7.4
Laz trunk/FPC trunk x86, Windows: GDB 7.4

It works here. Win Vista 32 bit gdb 7.4 fpc 2.6.0

It stops at procedure Ttestexport1.Setup;

And in LPR adding the following code
  for i:=1 to Paramcount do

B:\tmp\dbg_app_args\testmultiline.exe -a

Please use the above to ensure if the argument is or is not passed.

Please supply a log as described

You may also try to quote the entire argument(s). "-a" (if multiple args, only one quote for all "-a -all")

It may be a gdb 64 bit issue. (though 7.5 may cause other problems. It currently fails some watches data)
Try updating

try "--all"

Didn't notice that the report specified x64. My test was on win xp 32. Tried also 7.2 which fails also.

> prints
> B:\tmp\dbg_app_args\testmultiline.exe -a
> -a
-a is mentioned in the report as working

> try "--all"
"--all" is mentioned in the report as working

Only --all fails. Looks as if --all is an undocumented parameter for -exec-arguments on gdb windows. This is confirmed by the following test:
1)start gdb from the command line with --interpreter=mi. Enter: -exec-arguments --all. Enter: show args. Returns: ~"Argument list to give program being debugged when it is started is \"\".\n"
2)start gdb. Enter: set args --all. Enter: show args. Result: Argument list to give program being debugged when it is started is "--all".

Do the same while replacing --all with for example --alll and the results are the same in both modes.

@Martin,Anton, thanks. Please read the bug report. As mentioned in the report, I tried -a and "--all" with success. The point is that --all doesn't work, it's not documented that it shouldn't etc. Please test with --all instead of -a or "--all"

The bug report was made on x64 Windows but with x86 FPC/Lazarus, as indicated e.g. in Additional Information. I've updated my profile to indicate I'm using the x86 compiler; hope that is clearer.

GetCommandLine function does not exist... (perhaps it does in Delphi)

Attached is the test program and the debug output, run with --all, Lazarus x86, SVN 38659, FPC 2.7.1 r22397

Martin forgot to say you need to add Windows to the uses clause.

Ok, indeed --all does not work.
Tested outside the IDE: DGB does remove it for some reason.

There in no documentation for GDB (not that I found). So this issue is currently not fixable.

Thanks, Martin. Mentioned it in; perhaps a note in the debugger wiki articles would help too?

I'm sure you have thought about an upstream bug report... but I know you're a busy man.
Happy with whatever status you want to assign to this bug...

Perhaps close this as unable to fix?
