Concurrent Modification of separate sections of my MediaWiki always result in conflicts - merge

I have set up a private mediawiki server for the purpose of documentation of a group project, everything is working nicely except for when two users attempt to edit the same article.
When using Wikipedia multiple users are able to edit separate sections of the same article without it causing merge conflicts, but for some reason I am experiencing merge conflicts on my mediawiki server under the same circumstances.
Product and Version:
MediaWiki - 1.18.1
PHP - 5.2.17 (apache2handler)
MySQL - 5.1.57
I have tried the usual search and you will find technique, but unfortunately I have not been able to find any reason for this to be happening. It is very frustrating to not be able to have concurrent modification on our articles.

Automatic resolution of simultaneous edits is done by shelling out to the GNU diff3 command; if it's not found at installation time (or if it's no longer callable) then all conflicts must be resolved manually, even if they're plainly separate sections.
Check your LocalSettings.php for a bit like this:
# Path to the GNU diff3 utility. Used for conflict resolution.
$wgDiff3 = "/usr/bin/diff3";
and make sure it's correct. If it is correct, check that there's no limitations on PHP shelling out to programs (safe mode etc).

How to transfer files with Tramp using scp or rsync

I've read the TRAMP manual and dozens of forums across the web but I couldn't find an answer to this question. I am trying to set up a link in org-mode that transfers a file from a remote server to my local machine (or vice-versa).
According to the manual I have to write something like
/scp:user#host:filepathonremotemachine
and that's it. No specification of where the file should be moved to, which is weird.
I've tried to do it this way and it simply opened the file (as if I was using ssh); tried other combinations also, without any luck.
There is a specific reason for why I am trying to do this with tramp and not a shell:command link. Any help is very welcome
UPDATE
Apparently TRAMP is less useful than what it promises. That leaves me with the shell:command link option. The problem then revolves around avoiding the openssh window that pops out. The closest solution I found was here and it resumes to setting up an ssh-agent. I am not very familiar with this procedure and I would prefer to use the authinfo.gpg authentication method. Do I have this option? Thanks.
Tramp itself offers just alternative implementations of native Emeacs functions. In this sense, it is dumb, as every library, because it doesn't know what the caller wants.
I'm not an org-mode specialist, but could you please show, which kind of link you have in mind? Without any remoteness, just a link which copies a file locally. Replacing local file names with remote ones will be easy then.
I assume, you need something like an external link, evaluating Lisp code. Like
elisp:(copy-file "/path/src" "/path/target")
The following works (for some definition of "works"):
* link to copy a file
[[shell:scp remote.host.com:/path/to/file /tmp][scp]]
But you must have arranged for passwordless login to the remote host beforehand (e.g. ssh-copy-id your public key to the remote): given that, there is no output in the org buffer, no openssh popup, just the standard question from org-mode asking if you really want to execute the shell command and the file is copied quietly to its destination.

TortoiseHg commit complains about non-ASCII characters in the message

The subject tells it all. In 2015, one of the modern VCS doesn't want to accept multilingual commit messages. Though my main development language is English, I need to be able to comment on non-English stuff happening in the software. (I wonder why a program would care to use anything but UTF-8 nowadays, but it's another story.) It says:
I've found several posts on the web, discussing similar issues, but somehow none of them covers exactly this, nor do I understand how to solve the problem. I have already tried setting the system variable
,
but TortoiseHg doesn't seem to notice the difference. On the other hand, I am not sure if I set it correctly.
You set HGENCODING as a system variable in Windows. That generally requires a restart to inherit the new environment in all processes. You may get away with closing and restarting TortoiseHg from the Windows Desktop as Explorer should get a notification that the variable changed and update its own environment.
I could reproduce the issue on my system, but once the variable is set correctly TortoiseHG committed just fine. Using HGENCODING=UTF-8 is a valid spelling for that encoding.

NetBeans: should nbactions.xml, nb-configuration.xml and catalog.xml go into source control?

This thread is very useful for finding out which files in Netbeans should go into source countrol, but it doesn't cover all files.
In particular I'm wondering whether the following files should go into source control. Here are my assumptions/guesses:
nb-configuration.xml - easiest - the file itself in the comment says it should go into source control.
nbactions.xml - from what I see this file stores information typical to running the application. I.e. JVM arguments etc. So I suppose it is a question of taste - if you want other developers to have a "suggested" Run configuration - include it. Otherwise - don't. Correct?
catalog.xml - not sure what this does (I GUESS it's used by the editor to find out xml schemas and such to enable syntax coloring, but it's just a guess). Anyway - I see that this file has system-specific information (path) - so it shouldn't go into source control.
Can anyone confirm the above?
Thanks,
Piotr
I never put my IDE configuration files in the repository, for several reasons:
other colleagues may want to use theirs;
other colleagues may want to use other IDEs (such as Eclipse) and seeing those files (or even have to exclude them from the checkout) could be annoying for them;
some of these files are generally not related to a single project, others automatically generated, so no need to store them in the source code of every project.
In order to exclude them, our first solution was the .svnignore, but it was still logically wrong to modify some shared content for the specific needs of a single user, so we decided to be more strict:
in my ~/.subversion/config I have:
[miscellany]
global-ignores = nbactions.xml nbproject
Hope this helps,
Marcello
In my Maven based projects I put nbactions.xml into source control. Just make sure to change absolute paths to relative ones.
I put nbactions.xml into source control BUT there is a caveat: it's internal format can change so if your developers, for any reason, use different versions of NetBeans you could have to remove it because sharing it becomes nasty.
Recently I upgraded from NetBeans 7.3.1 to 7.4 and the "Run" action was giving a strange error message. I solved the problem by deleting and regenerating nbactions.xml: the old one had a custom Maven goal for the "Run" and "Debug" actions; it was org.codehaus.mevenide:netbeans-deploy-plugin:1.2.4:deploy it was not visible in the IDE v7.3.1 (perhaps it has been generated by an even older version for internal usage) and was generating a class not found for org.openide.util.Lookup in v7.4. I'm documenting the problem here because I found the solution by myself after an unsuccessful search on the Net. I hope this can help someone else.

Hybrid version control & sync system?

Is anyone aware of a hybrid version control and synchronising system?
I'm currently a happy mercurial user, but my projects usually contain a mixture of files.
Most of these (code, documentation, ...) I want to be version-controlled. This is why I use mercurial.
However, on the rare occasion I have files that I would like to synchronise between my working copies, but not version control.
For example, I version control the code I write to do image processing. This code can produce a whole bunch of output images which I'd like to have synchronised so I don't have to remember to shuffle them around my various computers, but there's no point having these version controlled.
To clarify - I am aware of extension to mercurial such as bfiles and bigfiles, which are handy for my image example, but I was just wondering if anyone out there knows of alternative ways to handle this. I just want the one system that I can tell "version control all files except those ones, which should be synced but have no history".
cheers!
EDIT: I could do something like adding a hg marksync <filename> that added <filename> to a list of files to be synced, and then adding a hook to hg push/hg pull that would (say) run rsync (or whichever sync tool) in the background, but I wondered if there was a less hacky solution (I think bfiles/bigfiles do something along these lines anyway).
Version Control System (any) doesn't care about synchronization of
not versioned data
besides default pathes
If you want sync any files - use specially designed for this task tools: f.e. rsync
This code can produce a whole bunch of output images which I'd like to have synchronised
Is this DATA or part of your CODE?
If data: Keep out of your versioning system, just don't go there. If it is part of your code (like layout images) check it in. Those are the only ways which are the generally accepted.
A nice solution for the data would be syncing OR generating them. So you might add a step after deployment to a server: GenerateImages().
edit: In addition to the comment made by the thread starter:
If the images are data and you need to process them on a different system don't think about the version control for your code. It is unrelated. The steps which would make sense to me, in order of processing:
Start with updating your image code, check it in versioning. Then deploy (yes this is deployment) the updated code to the cruncher computer. Now code is done.
Then you have tasks which the number cruncher should handle. Like processing the images. So start that processing from either the cruncher itself (probably some queue happens there) or from a central dispatcher.
Then you have the results locally at the cruncher. Now something has to happen with that data, so that's also part of your software. Decide whether you want the cruncher to send them to some central storage, your workstation or another location. Let the software handle that. This is the most hard part as I read through your question. Many solutions are possible from just FTP/network transfers to specific storage solutions. Willing to help but need more info about the real issues, amounts, sizes etc. on these parts.
If the new updated version of the image processor makes the old generated images obsolete implement that also in your code, by for example attaching an attribute to the files generated, a seperate folder or another indication. That way you could request the cruncher after update to re-generate any obsolete files.

Diff/Compare Tool That Lets Me Write Comments On Differing Lines

I'm looking for a diff/compare tool that shows differing lines from two text files, and gives me a space to comment on those files. Ideally this application would have three panes, pane one would be file A, pane two would file B and pane three would be a comment I can enter to on why the files are different.
We're going to be using this diff tool to compare test and production environments. Sometimes it'll be justifiable that the two files are different but we need to have a space to explain why. I'd rather not write those comments in the files themselves.
I've used TortosieMerge, WinDiff and Beyond Compare. I like beyond compare the most because it lets me see the whole file, just the differing lines or the differing lines in context.
Tools that sit inside Visual Studio or eclipse are fine too.
It sounds to me like you might want to use a code review tool for this (even if you're not really performing code reviews). They record diffs in a database and allow comments on those diffs.
A couple free ones are:
CodeStriker - I've used this and it works pretty well, but required more tweaking and mucking around in Perl that I'd have liked (that was a while ago, though)
Review Board - never used this, but it sure looks nice. I'm trying to get it installed at my current place of work.
I would like to suggest a high-efficiency software CodeGen to you. It's not only include TextCompare tools, but another Codec/Database tools is supported as well.
