After git clone and cd into sugar-build I get this error-Another osbuild instance is running on executing ./osbuild pull I searched the internet and found 2 such threads but the issue wasn't resolved. There's more than two such threads on sugar-devel at . Is this a bug that needs fixing? Yes, it's a bug in osbuild, please fix it. Hello James, I made the following changes in check_lock() def check_lock(): -try: -fcntl.lockf(get_lock_file(), fcntl.LOCK_EX | fcntl.LOCK_NB) -except IOError: -return False - -return True - + pid = os.getpid() + try: +fcntl.lockf(pid, fcntl.LOCK_EX | fcntl.LOCK_NB) + except IOError: + return False + try: + os.kill(pid(), 0) + except OSError: +return False +return True Ah, that's not what I meant. But I was wrong to suggest a redesign using getpid and kill, because my analysis of the code _today_ shows the underlying cause must be something other than locking. Let me explain. check_lock does try fcntl.lock, and if an exception IOError occurs, does return False. But inside the same try clause is a call to get_lock_file. Therefore any IOError inside get_lock_file will also cause check_lock to return False. A possible error is that the file could not be opened for write, e.g. because it is owned by someone else, or the protection mask (chmod) is wrong, or the directory does not exist, or the directory is protected. def check_lock(): lock_file = get_lock_file() try: fcntl.lockf(lock_file, fcntl.LOCK_EX | fcntl.LOCK_NB) except IOError: return False return True As a result of this change, any problem opening and writing to the file will be reported before the "another instance" error. Ah Got it! Thanks :) Like you said it's a permission error. I've posted it below - Traceback (most recent call last): File "./osbuild", line 504, in if not main(): File "./osbuild", line 467, in main if not check_lock(): File "./osbuild", line 406, in check_lock lock_file = get_lock_file() File "./osbuild", line 90, in get_lock_file lock_file = open(get_lock_file_path(), "w") IOError: [Errno 13] Permission denied: '/home/shraddha/git/sugar-build/.lock-host' Okay, that will certainly stop osbuild from working. so that when there is no process running false is returned. However it is not fixing the bug. And yeah when I try to delete the lock file, I get 'file or directory doesn't exist' That's not possible to explain given the data you sent. You said the print statement showed the file path as .../git/sugar-build/.lock-host Presumably ... is something like /home/username Does the .lock-host file still exist? Show me "stat .lock-host"? If the file exists, but you cannot delete it, then osbuild will fail to open it for write. stat: cannot stat ‘.lock-host’: No such file or directory This is what I get. It's confusing that although it's failing to write, stat says no such directory exists! Ye, that is strange. On the one hand the file exists and cannot be opened for write, yet now the file does not exist. Please check you are in the right directory when you use stat, or use stat with the same full path to the file (as reported by osbuild); stat /home/shraddha/git/sugar-build/.lock-host I'm trying not to presume any knowledge; if you only type "stat .lock-host", then the stat program will look for the file .lock-host in the current directory. You can see what the current directory is by typing "pwd". You can change the current directory using the "cd" command. stat: cannot stat ‘/home/shraddha/git/sugar-build/.lock-host’: No such file or directory I'm searching why this is happening. Meanwhile if anything strikes you do let me know Since the open does fail, and yet the file does not exist, the problem must be in creating the file. The most likely cause is owner or protection mask of the directory; the directory in which the file is to be created, so please check: stat /home/shraddha/git/sugar-build Example expected output; File: ‘/home/use/git/sugar-build’ Size: x Blocks: xx IO Block: directory Device: xxxh/d Inode: Links: xxx Access: (0755/drwxr-xr-x) Uid: ( 1000/ user) Gid: ( 1000/ user) Access: 2016-01-02 17:15:56.881528661 +1100 Modify: 2016-01-02 17:14:19.290923184 +1100 Change: 2016-0

You said the print statement showed the file path as .../git/sugar-build/.lock-host Presumably ... is something like /home/username Does the .lock-host file still exist? Show me "stat .lock-host"? If the file exists, but you cannot delete it, then osbuild will fail to open it for write. stat: cannot stat ‘.lock-host’: No such file or directory This is what I get. It's confusing that although it's failing to write, stat says no such directory exists! Kind Regards, Shraddha Sorry for the novice questions :( When you see me say something that doesn't match what you see, please be sure to tell me about it!

[Sugar-devel] MusicBlocks
I have worked a bit with Music Blocks and I feel that it is a really nice Activity but the problem is that there are just too many features and not enough documentation on them or the code properly structured. Even the code needs some nice comments form documentation so that the new developers as well as the users understand it properly. I suggest that the activity should go on a feature-freeze for some time and in the time it should be documented and structured. (is this the right place to be saying this?)
