Bug ID: 46028 Summary: Provide separate debug/symbol info files (.pdb) for 32-bit and 64-bit Wine-Gecko 2.47+ package (unstripped 32-bit 'xul.dll' too large to be mapped) Product: Wine-gecko Version: unspecified Hardware: x86 OS: Linux Status: NEW Severity: normal Priority: P2 Component: wine-gecko-unknown Assignee: jacek@codeweavers.com Reporter: focht@gmx.net Distribution: ---

Hello folks,

while investigating some crashes in Gecko's xul.dll I came across the missing debug symbols again. Bug 36941 repeated.

https://wiki.winehq.org/Gecko#Debug_info

For the 32-bit part this is pointless as the unstripped 32-bit 'xul.dll' will be always be too large for mapping. Split out symbols via PDB is a must.

--- Comment #1 from Austin English austinenglish@gmail.com --- Last I tried this, I was blocked by wine pdb issues, because gecko needs at least msvc 2013, iirc.

At least these two come to mind: https://bugs.winehq.org/show_bug.cgi?id=37746 https://bugs.winehq.org/show_bug.cgi?id=38594

If we update our Gecko package, we could use that. The problem is that a number of interfaces we use in MSHTML (see nsifacei.idl file) were removed from upstream Gecko meantime, so updating is going to be hard.

Recently Firefox mingw builds were moved to clang-based toolchain. clang has support for .pdb files: https://bugzilla.mozilla.org/show_bug.cgi?id=1475562 https://bugzilla.mozilla.org/show_bug.cgi?id=1497645

The problem isn't generating the pdb. The problem was that wine's dbghelp/kernel32 couldn't work with newer pdb formats.

I wasn't able to find what version format clang uses, but if it's too new they won't work out of the box for us.

that's not really an issue for me. I rarely use builtin dbghelp for debugging due to various bugs/missing newer functionality. Only when using winedbg which rarely happens (winedbg is mostly unusable for application debugging).

Sorry, I was unclear.

There are 2 overall issues: 1) Bug 46028 (this one) - we don't provide .pdbs for users to use 2) Bug 38594 - if we do provide .pdbs, and they're in msvc 2013+ format, they're completely unusable with Wine's dbghelp.

In fairness, it's possible that clang's pdb's do work in wine, I haven't tested them. I'll make a note to test if I get time. From comment #5, it sounds like native dbghelp works with the 2013 (and presumably clang) pdbs, which may serve as a workaround.

--- Comment #7 from Anastasius Focht focht@gmx.net --- Hello folks,

is there a plan to provide the next Wine-Gecko release built with llvm-mingw? Last Wine-Gecko 2.47.1 release still provides only unstripped binaries:

http://dl.winehq.org/wine/wine-gecko/2.47.1/

Jacek commented recently about llvm-mingw status here: https://www.winehq.org/pipermail/wine-devel/2019-December/157038.html

There is another bug about general PDB support in Wine: bug 15489 ("Build should optionally produce .pdb file suitable for use with symbol server").

For me PDBs created llvm-mingw with would be perfectly fine. I have a local symbol store/server with Wine PDBs working. It needs native dbghelp (DIA SDK) + symsrv because I use native debuggers. Winedbg is just awful for most debugging tasks.

$ wine --version wine-5.0-rc3

--- Comment #8 from Jacek Caban jacek@codeweavers.com --- Yes, I hope to move Wine Gecko builds to llvm-mingw. However, the port requires quite a few fixes. Most of them are in newer upstream, see [1] for an overview. I expect it to require some non-trivial cherry-picks and fixes specific to the version we use. I hope to do that, but didn't get to that yet. Once the move to llvm-mingw is done, providing .pdb files should be easy.

This patch enables pdbs to be built. Currently it doesn't install them anywhere; I wasn't sure if they should go in the dlls directory or into their own directory.

I can confirm the provided tarballs containing PDB files for MinGW builds work for both, 32-bit and 64-bit Wine-Gecko.

Method 1: Extraction into WINEPREFIX (PDB live alongside the dlls).

It can be also run against a whole directory to validate all files.

I've tested with x64dbg and builtin 'iexplore.exe' as well. The Wine-Gecko symbols take some time to load because of the huge number but eventually show up.

Source level debugging obviously won't work with debuggers requiring native MS DIA/dbghelp due to Unix paths (general problem). But who needs source level debugging anyway.

In further future it might be feasible to distribute the PDB files for official Wine releases and its dependencies (Gecko, Mono) by using a symbol server/store (serve directory with a web server).

Setting up a symbol store is not very hard (https://gist.github.com/rmi1974/90f14258c622fe57a9b70f6cabe69d66). There even exist Python tools mimicking the symstore tools from Debugging Tools for Windows (https://pypi.org/project/symstore/).

Bit off-topic: I hope the conversion of the remaining Wine builtins to PE format can be finished before Wine 6.0 release. That would be awesome ;-)

New subject: [Bug 46028] Provide separate debug/symbol info files (.pdb) for 32-bit and 64-bit Wine-Gecko 2.47+ package (unstripped 32-bit 'xul.dll' too large to be mapped)

Hello Jacek,

I can confirm the provided tarballs containing PDB files for MinGW builds work for both, 32-bit and 64-bit Wine-Gecko.

Great, thanks for testing.

...

Method 1: Extraction into WINEPREFIX (PDB live alongside the dlls).

64-bit:

--- snip --- $ tar xJvf ~/.cache/wine/gecko/wine-gecko-2.47.2-x86_64-pdb.tar.xz \ --directory ~/.wine/drive_c/windows/system32/gecko/2.47.2/wine_gecko/ \ --wildcards '*.pdb' --strip=1

wine-gecko-2.47.2-x86_64/browsercomps.pdb wine-gecko-2.47.2-x86_64/xul.pdb wine-gecko-2.47.2-x86_64/mozavutil.pdb wine-gecko-2.47.2-x86_64/nss3.pdb wine-gecko-2.47.2-x86_64/clearkey.pdb wine-gecko-2.47.2-x86_64/plugin-container.pdb wine-gecko-2.47.2-x86_64/mozavcodec.pdb wine-gecko-2.47.2-x86_64/libGLESv2.pdb wine-gecko-2.47.2-x86_64/libEGL.pdb wine-gecko-2.47.2-x86_64/lgpllibs.pdb wine-gecko-2.47.2-x86_64/mozglue.pdb --- snip ---

If this usage pattern is common, then we can ship a tar containing only .pdb files so that there is no need to filter. The way I ended up doing it is a bit more convenient for using with shared build. You can just extract *-pdb.tar.xz files into /opt/wine/gecko/ and it should just work without creating copies in each prefix.

Agreed, it would be interesting.
