Wireshark · Wireshark-dev: Re: [Wireshark-dev] Wireshark PIDL generated dissectors

[Pascal Quantin <pascal.quantin@xxxxxxxxx>]

Hi,

there is also a small issue spotted by checkAPIs.pl script (found in tools folder) leading to a failure of the buildbot:
Error: the name for hf_frsrpc_frsrpc_FrsVerifyPromotionParent___ndr_guid_size ("frsrpc.frsrpc_FrsVerifyPromotionParent.__ndr_guid_size") has leading space in packet-dcerpc-frsrpc.c
Error: the name for hf_frsrpc_frsrpc_FrsStartPromotionParent___ndr_guid_size ("frsrpc.frsrpc_FrsStartPromotionParent.__ndr_guid_size") has leading space in packet-dcerpc-frsrpc.c

I fixed them manually in r53072 but you probably want to change the code generator so as to remove the prepended spaces.

Best regards,

Pascal.

PS: checkhf.pl script also found the following error:
Unused entry: epan/dissectors/packet-dcerpc-frsrpc.c, hf_frsrpc_frsrpc_CommPktChangeOrderCommand_file_name

Matthieu,

 

I committed 0010-frsrpc-Regenerate-frsrpc-due-to-changes-in-the-pidl-.patch and 0016-Regenerate-the-dnserver.patch with the necessary changes to get it to compile on Windows to r53067.  As the commit message mentions, I think the PIDL generator may need to be updated in order for dissectors to compile on Windows.

 

Michael

I may have slightly misspoke about the patch in bug 9301 causing the compile errors, but the patch in bug 9301 had the same compile errors on Windows as the generated dissectors.  I originally committed the patch in r52734 before realizing the compiler errors which I corrected in r52735 (with a simple cast).

Yes I saw your patch for the bug 9301. But in theory I could resubmit the two patches because the errors weren't in the patch but in the use it made of the funcion in bug 9301

I don't have access to a Linux box, but I suspect if you used Linux to generate the patch in bug 9301, you won't see this issue either with the generated dissectors. It appears the generated dissectors need extra casting to compile on Windows and I didn't just want to make the fix in the Wireshark source.

Also do you have some kind of buildfarm, I'm ok to build patches there before submissions.

Matthieu.

for how it was fixed.  Not sure if the PIDL compiler has to be changed for this 
one.
Can you tell me what were the compile errors on linux, it's seems just 
fine with just this patch on top of the recent svn trunk.

I just have warnings for dnsserver:
