Re: Patch : PGPASSFILE fix - Mailing list pgadmin-hackers

Alright , I'll revert to PGPASS check.
Existing function only creates folder containing file. With this case, whats expected ? Reading value in PGPASSFILE and
tryto create folder containing pgpass file (Assuming it's valid path)? Remember, it's environment variable. User can
specifyanything in there. Some garbage value as well. If we don't do any validation there, user will automatically see
errorwith complain about file ? 

thanks and regards,
Prasad

Ashesh,

Thanks for reviewing patch, 
Code I have removed in I think, was switch statement inside if condition, which doesn't make sense.
ie.
if (var == 2)
{
     switch (var)
          case 2:
             .....
             break;
}

that's why I removed it, because it's redundant.
Agree about redundancy, but you've also removed the code for checking the PGPASS check at the start of the function.
i.e.
@@ -762,35 +762,33 @@ void sysSettings::SetCanonicalLanguage(const wxLanguage &lang)
 //////////////////////////////////////////////////////////////////////////
 wxString sysSettings::GetConfigFile(configFileName cfgname)
 {
-   if (cfgname == PGPASS)
-   {
 
I am not agree with that.
 About creation of directory, I'm not sure if this validation is required. Existing code creates directory postgresql
(onlyon windows) according to
http://www.postgresql.org/docs/9.3/static/libpq-pgpass.html[http://www.postgresql.org/docs/9.3/static/libpq-pgpass.html]
,and it doesn't create file. I'm not sure whether this kind of validation is expected in this function. 
I think - it is.
Because - it could be used to save the updated password in the PGPASS file.

Hi Prasad,
 I see couple of issues with your patch.* Please generate the patch using 'git diff'.
  I could not apply your patch straight forwardly.
  I had to use the patch utility.
 * Please follow the coding style of pgAdmin.
  You can find it at
https://wiki.postgresql.org/wiki/PgAdmin_Internals#Coding_Style.*[https://wiki.postgresql.org/wiki/PgAdmin_Internals#Coding_Style.*]
Donot remove any of the existing code. 
  It has been kept there keeping in mind about future development extending support of the existing functionality.
  You've removed couple of lines in the sysSettings::GetConfigFile(...) function, which is not good.
 
In your code:* Checked only for PGPASSFILE environment variable.
* Need to check the existence of the file.
* Take required actions (if that file/parent directory does not exists).
    i.e. Create parent directory
