Package: boinc-manager
Version: 5.10.8-2
Severity: normal
Hi,
I was try to create a new account by following steps:
1) Open "Attach to project" dialog,
2) Select "[EMAIL PROTECTED]" and click "Next",
3) Input an E-mail and password and click "Next",
4) An error "missing or bad parameter: user_name" occurs.
I have used Wireshark to see what data boinc-manager sent, and here is a HTTP
request:
GET
/rosetta/create_account.php?email_addr=<...snip...>&passwd_hash=<...snip...>&user_name=
HTTP/1.1
User-Agent: BOINC client (i686-pc-linux-gnu 5.10.8)
Host: boinc.bakerlab.org
Accept: */*
Accept-Encoding: deflate, gzip
Content-Type: application/x-www-form-urlencoded
Note that the user_name parameter is empty.
I have looking for how to change the user_name parameter, but I can't find
anything.
There is no inputbox for the user_name in "Attach to project" dialog nor
Setting dialog in boinc-manager.
I have looked up the source code of boinc-manager and found following code:
boinc-5.10.8/clientgui/ProjectProcessingPage.cpp
ai->user_name = (const char*)::wxGetUserName().mb_str();
The function wxGetUserName is a function of wxwidgets.
According to the manual of wxwidgets, wxGetUserName returns "Full User Name".
http://www.wxwidgets.org/manuals/stable/wx_networkfunctions.html#wxgetusername
I have looked up source code of wxwidgets.
Here is a wxGetUserName defined in wxwidgets2.6-2.6.3.2.2/src/unix/utilsunx.cpp:
bool wxGetUserName(wxChar *buf, int sz)
{
struct passwd *who;
*buf = wxT('\0');
if ((who = getpwuid (getuid ())) != NULL)
{
// pw_gecos field in struct passwd is not standard
#ifdef HAVE_PW_GECOS
char *comma = strchr(who->pw_gecos, ',');
if (comma)
*comma = '\0'; // cut off non-name comment fields
wxStrncpy (buf, wxSafeConvertMB2WX(who->pw_gecos), sz - 1);
#else // !HAVE_PW_GECOS
wxStrncpy (buf, wxSafeConvertMB2WX(who->pw_name), sz - 1);
#endif // HAVE_PW_GECOS/!HAVE_PW_GECOS
return true;
}
return false;
}
Actually, this function retrieves 5th field (pw_gecos) in /etc/passwd entry for
the current user.
My 5th field in /etc/passwd was ",,,", it means empty because wxGetUserName will
cut off after first comma, so I changed it to "abc,,,".
And I tried to create a new account in boinc-manager.
As result, it succeeded with no error.
Here is a HTTP request sent in that situation:
GET
/rosetta/create_account.php?email_addr=<...snip...>&passwd_hash=<...snip...>&user_name=abc
HTTP/1.1
User-Agent: BOINC client (i686-pc-linux-gnu 5.10.8)
Host: boinc.bakerlab.org
Accept: */*
Accept-Encoding: deflate, gzip
Content-Type: application/x-www-form-urlencoded
Note that user_name parameter have "abc".
I know user_name parameter is taken from 5th field in /etc/passwd,
and if user_name parameter is empty, "missing or bad parameter: user_name"
error will occurs.
Since 5th field in /etc/passwd is optional, boinc-manager should not assumes it
is non-empty.
I have some idea to fix (or mitigate) this problem.
* Add inputbox for user_name to the "Attach to project" dialog and
use wxGetUserName() as its default value.
* Use other non-empty value if wxGetUserName() returns ""
