Jan Rysavy 8 Posted June 14, 2022 (edited) I would like to implement support for reading of JEDI .jdbg files: https://bitbucket.org/anders_melander/map2pdb/issues/2/parser-for-jdbg-files Does anyone know if .jdbg parser code exists? Otherwise I can probably write it based on TJclBinDebugGenerator.Create: https://github.com/andremussche/asmprofiler/blob/b785168f7caec8ff91d59d912dfb0e9e4519f803/Source/EXT/jcl/JclDebug.pas#L2358 Edit: nevermind, found .jdbg parser - TJclBinDebugScanner.

Mahdi Safsafi 225 Posted January 12, 2023 Excellent work ... Thanks ! I was using the tool with some map file and I got an AV error. I started investigating and I found a bug in the map parser : // debug.info.reader.map.pas (line 349): var SegmentID: Cardinal := HexToInt16(Reader.LineBuffer, n); The SegmentID should be read as a DECIMAL value and not as a HEX ! if the map file contains more than 9 segment, the next segment is emitted like (0010:xxxxx) but you're reading it like a hex (so its ID becomes 16 !) and then there is this line FSegments[ListIndex] := Result; // FSegments[10 .. ListIndex - 1] = nil => AV A simple fix : function DecToInt32(const s: string; var Offset: integer): integer; var P: PChar; begin Result := 0; P := PChar(s); while Ord(P^) in [$30 .. $39] do begin Result := (Result * 10) + (Ord(P^) - $30); Inc(P); Inc(Offset); end; end; // ... var SegmentID: Cardinal := DecToInt32(reader.LineBuffer, n); 3 Share this post Link to post

Anders Melander 1795 Posted January 12, 2023 Yup. That pretty much sums it up. Like everything else Atlassian touches it only gets worse with time. My plan is to switch everything to Gitlab at some time but other stuff keeps getting in the way. 1 Share this post Link to post

I need to get some real-life experience with it anyway because I also plan to switch the company from BitBucket to Gitlab at some point. Github is way too expensive for enterprise use. 8 minutes ago, Vincent Parrett said: for gitlab you have to apply for free hosting of open source. I've had a Gitlab account for quite some time. AFAIR I didn't need to "apply". I think I just checked a box somewhere. Edited January 12, 2023 by Anders Melander 1 Share this post Link to post

David Champion 48 Posted January 13, 2023 @Anders Melander I am using Code Commit for my latest project, during lock down I needed to swap out the On Premise version of BitBucket. It has the feature of locating the service at a particular data center and encrypting the source code at rest. It's worth a look if you haven't already. Then again I don't know what you are looking for. 1 Share this post Link to post
Stefan Glienke 2009 Posted January 13, 2023 GitLab is amazing and you can host on-premise - for some people including our company, this is important. 1 Share this post Link to post

Jan Rysavy 8 Posted May 21, 2023 Are any of you running MAP2PDB with the current version of Intel VTune 2023.1? Both AMD uProf and WinDBG correctly load my PDBs created by the latest version of MAP2PDB, but VTune only shows function addresses without symbolic names. Share this post Link to post
shineworld 73 Posted May 22, 2023 (edited) Incredible tool, congrats. I've tried to use it with Sydney 10.4.1 and VTune 2023.1.0.

Jan Rysavy 8 Posted May 22, 2023 I just want to add that I installed an older version of VTune 2022.4.1 and the function names are displayed correctly. The problem seems to be related to the new version VTune 2023.1. Share this post Link to post

Stefan Glienke 2009 Posted May 22, 2023 (edited) I just upgraded from 2023.0.0 where it worked to 2023.1.0 where it does not. What I noticed in the change log of VTune 2023.1.0 is this: Debug Support Support for Large PDB Files Starting with the 2023.1 version, on Windows* systems, you can resolve debug information from PDB files larger than 4GB. Could it be that the address bitness written by map2pdb is not correct now? In the collection log of VTune I can see this warning: Cannot locate debugging information for file `somepath\Tests.exe'. Cannot match the module with the symbol file `somepath\Tests.pdb'. Make sure to specify the correct path to the symbol file in the Binary/Symbol Search list of directories.

Please create an issue at the repository: https://bitbucket.org/anders_melander/map2pdb/issues/new The problem is most likely caused by msdia140.dll; The library VTune uses to read pdb files. You can try replacing the one that VTune installs with an older version. See: Share this post Link to post
