NSS error

[fernando]

I have code that runs on linux machine A (Ubuntu) but fails on linux machine B (Debian) with the following error,

[0912/111839:ERROR:nss_util.cc(714)] Error initializing NSS with a persistent database (sql:/home/XXX/.pki/nssdb): NSS error code: -8187

The only difference (besides the distribution) is that machine B has an NFS mounted home directory which (according to some bugs, http://code.google.com/p/chromium/issue ... ?id=158915) may be the issue.

I'm running this headless and am not concerned about profile information, etc. Is there any way to address this in my scenario?

Thanks.

Is your user temp directory on the NFS mount or are you specifying a CefSettings.cache_path value? Try specifying a value that's not on the NFS mount.

[fernando]

I set cache_path to something not NFS mounted. Core parts of main() follow,

CefMainArgs main_args(argc, argv);
CefRefPtr<Application> app(new Application);
CefExecuteProcess(main_args, app.get(), NULL);
CefSettings settings;
CefString(&settings.cache_path).FromASCII("/data/XXX/cache/");
CefInitialize(main_args, settings, app.get(), NULL);
CefRunMessageLoop();
CefShutdown();

and receive the same error,

[0912/142213:ERROR:nss_util.cc(714)] Error initializing NSS with a persistent database (sql:/home/XXX/.pki/nssdb): NSS error code: -8187

Which is still referring to my home directory, not the directory set in cache_path.

[magreenblatt]

Looks like the NSS code is hard-coded to use your home directory in nss_util.cc (which makes sense because it's storing user credential information).

[fernando]

You're right. It looks like chromium flag "--homedir" allows you to change the value of "base::DIR_HOME". Do you know if there's some way to pass this up through cef? Throwing that switch does not seem to respect the new path.

[magreenblatt]

The "homedir" switch appears to only be supported on ChromeOS. The implementation is here. We could do something similar in CefMainDelegate::PreSandboxStartup() but it's probably better just to set the HOME environment variable to something on the local disk before running the CEF-based application.
