Mac-PPC; ExternalCmd dialog not detecting end of process

[isights]

Running Autopano does generate a CP file, but it's saved in a temp folder in the invisible var folder. The file also has no extension. It seems to be a complete .pto file and adding the extension does make it work.

Hugin also hangs at this point with the text below in the window. Trying to close the window or click the cancel button get the dialog box that says:
Hugin Error
Failed to kill process XXXX, Error 3: no such process

I have to force quit Hugin at this point. Loading the .pto file does make the program load the images and the control points are there. It optimizes well, but then when I tell it to stitch. nothing happens.
If I load the .pto into Hugin 0.6.1 it stitches fine.

Setting to 0.7.0 as your hugin seems to be hanging.

Otherwise there are good reasons why you wouldn't want to open this temporary project file, so it is best created in the temp directory.

I see exactly the same behavior. It used to work in 0.6.1.

Reproducible with RC4 on G4 867MHz Leopard machine.

The temporary file etc is the normal behaviour. The problem is that Hugin is not detecting the end of autopano-sift process. I don't have problem on my Mac mini with Intel CPU. It may have something to do with slowness of the machine, or could be general problem with PPC version.

[info needed]
Please give your machine details; CPU and speed, and OS version.

It seems PPC binary is universally affected even with rosette on intel machine. Priority heightened as this is critical and also affects stitching.

The cause is most likely inside the wxMac code. 2 tasks needs be done:
- Work around; as the ExternalCmd dialogs have Timer running anyway, should be able too check if the process has stopped every second or so.
- Report to wxWidgets bug tracker; quote this tracker item. In src/hugin1/base_wx/MyExternalCmdExecDialog.cpp, probably EVT_END_PROCESS event is not properly dispatched on PPC.

I'm running Hugin on an iBook G4, 1.33ghz with OS 10.5.4. It's got 1.25gb RAM and 175Gb free on the boot drive.
Each of the new builds errors in the same way after finding the CP.

I have committed a quick workaround to the repository: revision 3398.

wxMac on PPC somehow fails to notify us back the end of asynchronously launched process and leaves zombie process. The work around forces ignore the SIGCHLD signal hence letting child process terminate without becoming zombie, and checks the validity of pid in the OnTimer method hence detecting the termination of that process.

Unfortunately the workaround has to assume the external process finished successfully in any case, and that could lead to very bad confusion. Anyhow, at least with correct setup external process on PPC works smoothly now.

Please verify and close the case.
