The crash no longer occurs in Synergy 1.4.5 Beta

With both client and the server upgraded to Synergy 1.4.5 Beta from Synergy’s download page, the crash no longer occurs.

Segfault after Super keypress on client, upon return to server

Avainsanat: Synergy, Unity

This is on Unity 2D and Bug #780803 is at least tangentially related. Synergyc is connected to server through an ssh tunnel (which I set up according to http://ur1.ca/7g6o9#), with client positioned left of the server.

Steps to reproduce:
1. Bring mouse cursor from server screen to client screen.
2. Press Super on server keyboard.
3. Bring mouse cursor back to server screen.

What happens:
Synergyc dies with a segfault:
segfault at 8b0a75c8 ip 0062fbf2 sp bff05108 error 4 in libstdc++.so.6.0.16[5d8000+d8000]

(Also, pressing Super at step 2 brings up launcher on server, not on client – that’s probably Bug #780803 manifesting on U2D.)

Meaning and function of ’Revert’ ambiguous (particularly wrt ”Download from:”)

Avainsanat: saavutettavuus

I’ve specified three different specific cases to demonstrate what I mean by the title, below. I could have filed three different bite-sized bugs, but all in all I believe they are part of the generic accessibility problem with the ’Revert’ button that could be fixed in one go. (If the developers think otherwise, I’ll be happy to split this into different reports.)

When you first run Software Sources, ’Revert’ is ghosted as it probably should, implying no changes have been made that could be reverted.

Issue #1:
Steps to reproduce:
When Download from: is pointing at main servers, change it to something else and ’Revert’ becomes active. Now click ’Revert’, and main servers are restored as Download from: site.

What happens:
’Revert’ stays active, implying there are still changes left to revert. Clicking it does nothing of course, as all changes have just been reverted.

What should happen:
’Revert’ should become ghosted once pressed after becoming active.

Issue #2:
Steps to reproduce:
Point Download from: to your local mirror (other than main servers). Close Software Sources. Start it again. ’Revert’ is now ghosted, implying there are again no changes to be reverted. Point Download from: to a third mirror, and ’Revert’ becomes active. Click ’Revert’.

What happens:
Download from: now points to main servers.

What should happen:
I’d expect it to point to my local mirror, which was the initial state opening the window.

Issue #3:
Perhaps ’Revert’ wrt the Download from: site means not reverting back to initial state of this SS session, but reverting back to the very initial state of pointing to main servers. But in that case, ’Revert’ should *not* be ghosted when Software Sources starts with Download from: pointing somewhere else, as it just did.

Python-gobject 3.0.3-2 here and I’m able to reproduce this

Python-gobject 3.0.3-2 here and I’m able to reproduce this. I haven’t got an exact recipe for it, but enough wiggling around in software sources (with the mirror and such) seems to bring it on. I *think* it happens only when I finally close the window and not before. I’ll keep looking for the exact steps, but I’m pretty confident this is still unfixed, as apport always points me to this report.

Thanks for the Google Music Manager application-specific password solution

@Roger: Thanks for the solution. On Ubuntu Precise, GMM 1.0.23.1334-r0 seems to use /usr/local/share/applications instead of /usr/share/applications for the desktop file (there’s also a copy in /opt/google/musicmanager/, but it’s apparently just used for installing the effective file into /usr/local/).

@Nuno: I’m not sure I see the point of encrypting the application-specific password, and then be prompted to enter the key for decrypting the password. Isn’t it more straightforward to just specify the application-specific password when GMM prompts you to? Actually, with the caveat that specifying the password on the commandline means exposing it to trusted users, isn’t having GMM prompt for it a *better* solution securitywise? I guess you do get the benefit of getting to specify your own password which can be as easily memorizable as you dare use though (the application-specific passwords are difficult). Instead of OpenSSL I’d probably use GNOME Keyring, as it gets unlocked during login without an extra prompt for another password. Then pick the key for GMM using gkeyring.

I’ve found an MP3 file that does the same

I’ve found an MP3 file that also exhibits this. Can’t link it for © reasons, but I’ve got it here for testing.

Inserting newlines

There was a topic about replacing br tags with newlines on Urban Giraffe, but it seems to have led nowhere, so I’m posting this here just so that I can find it when I again need it, and maybe of help to others too.

I modified the search_and_replace function on line 37 of models/search.php so that $this->replace is assigned a replaced string itself:

$this->replace = str_replace("\\n", '
', $replace);

This means I want to replace any occurences of ”\n”’s in my replacement string with actual newlines just prior to applying the replacement.

It’s an ad hoc solution which I’m reverting once I’m done with newlines. I’ve not explored any possible side effects this solution may have, so use with caution.

Edit: Forum ate my br.

Voisin periaatteessa käyttää tuon kilkkeen tarjoamaa tietoa blogatessani

Tuon lisäksi, mitä Riku sanoi, ainakin itse ajattelin, että voisin periaatteessa käyttää tuon kilkkeen tarjoamaa tietoa blogatessani siten, että jos linkittäisin liputettuihin sivustoihin, mainitsisin SOPAn siinä yhteydessä. Voisin siis levittää tietoa edelleen. Toisaalta voisin myös jättää linkittämättä, mikäli tarkoitus on vinkata kaupantekomahdollisuuksista kyseisen tahon kanssa (vaihtaa esimerkiksi iTunes-linkin jonkin toisen musiikkikaupan linkkiin). Ilman lisäosaa jokaisen linkin takaa löytyvän tahon SOPA-kantaa tuskin tulisi erikseen tarkistettua, lisäosan kanssa se selviäisi viimeistään samalla kun testaisin linkin toimivuutta.

Aika rajalliset käyttötarkoitukset siis nähdäkseni, mutta sinänsä varmaankin varsin hyödyllinen väline niissä jotka sillä on.

Currently I’m unable to bring up X entirely with the intel driver

I should note that currently I’m unable to bring up X entirely with the intel driver. Too bad I didn’t make a note of which upgrade this started with. With intel it now just freezes when login screen should appear, with just the cursor showing on a purple background. It’s such a tough lockup that REISUB from the keyboard won’t work, I have to power off to reset. Comparing logs might help determine if it’s the same issue on a grand scale or an unrelated one, but I don’t know how (or if) I can get useful logs from such lockups.
