run command (alt+F2): results do not contain the exact match

[Paul]

Test case:
1. Open the run command dialog (Alt + F2)
2. Type in the search field: evolution
   -> When evolution is installed, the results should show the exact match first (evolution), and others later (like evolution-settings)

3. Clear the search field
4. Type in the search field: wine
   -> When wine is installed, the results should show the exact match first (wine) followed by other applications matching the query

===

when using the ´run command´ dialog (ALT + F2) search results are shown real time below. My expectation is that the exact match is also shown in the search results. In some cases the exact match will not be shown.
for example:
"evolutio" will yield the result "evolution" and "evolution-settings"
"evolution" will only yield the result "evolution-settings"
==> although evolution matches exactly the executable file the program is not listed in the results.

"wine" will show several matches starting with wine, but not wine it self. "win" would do.

But in other cases the exact match is displayed:
"gedit" will show the expected result.

My assumption is that the exact match is not shown if more than one match is available. If only one program matches the input, the program is displayed.

The problem here might be an "off-by-one" bug...

- alt+f2 and type "gvim", I get the results:

gvimdiff
gvimtutor

...whereas on the console command-line, typing "gvim"+TAB we have:

gvim <--- XXX: missing in unity
gvimdiff
gvimtutor

- alt+f2 and type "mumble" I get the results:

mumble-overlay

...whereas on the console command-line, typing "mumble"+TAB we have:

mumble <--- XXX: missing in unity
mumble-overlay

Attaching Screenshots of the bug

[Damiön la Bagh (kat-amsterdam)]

Here is the screenshot from the terminal showing that the application exists

[Damiön la Bagh (kat-amsterdam)]

Workaround is to type one less character and click the program with the mouse

so to open x3270
you would do

alt+F2
x327
Mouse left-click x3270 from the lens (RSI anyone?)

Same with "firefox" command. Highly irritating bug.

[Thibault D (thibdrev)]

same with evinc / evince

[David Murrell (david-murrell)]

Fixed with this patch, I think.

I'm not quite sure what the original reasoning was there, but I'm sure it made sense at the time :)

[rgrig (radugrigore)]

There is another comparison "!= search_string" above David's patch that makes it fail if someone types "/usr/bin/evince"

[Sebastien Bacher (seb128)]

bug #912768 is about the same issue, typing "mumble" leads to mumble not being listed

[Péter Trombitás (trombipeti)]

I think some solution/workaround would be to execute the search_string if it is a command, and if not, then execute the first match. I don't know vala so I don't know how/whether it could be done, but looking at the source code with all my python knowledge - that is not a lot:) - it seems possible.

[Péter Trombitás (trombipeti)]

Does this make any sense? I can't test it:P
in runner.vala:
around line 56:
    private Settings gp_settings;
+
+ private bool search_string_executable = false;
around line 246:
      /* complete again system executables */
      else
      {
        foreach (var exec_candidate in this.executables)
        {
          if (exec_candidate.has_prefix (search_string)) // this line is changed as in David's patch
+ {
+ if (exec_candidate != search_string)
+ {
+ executables_match.add (exec_candidate);
+ }
+ else
+ {
+ search_string_executable = true;
+ }
          }
        }
      }
and around line 272:
      // 1. enable launching the exact search string if no other result or if it's executable
      if ((executables_match.size == 0) && (dirs_match.size == 0) || search_string_executable == true))

I don't think that it's a duplicate, since this bug is coded in the
runner.vala file and we know how to get rid of it, but doing so would cause
other problems (if I get everything well:))

Sorry, that _is_ a duplicate, but the bugzilla gnome is not related IMHO.
