I recently updated eclipse to the latest Oxygen version.
I don't really mind much if I am not using the latest version of each software, but whenever eclipse prompts me to update something, I go ahead and accept it as I trust it knows what it's doing. Since I have some plugins installed and since I've had eclipse for quite some time, I have a long list of software sites listed in my Install/Update preference pane.
Lately some of these sites seem to have stopped responding, so I removed them from the list. Upon clicking on help > check for updates however, they simply come back to the list.
Could someone explain to me why this keeps happening and why I am unable to control what eclipse is contacting?
An installed feature can contribute an Update Site if they want. Your best bet is to leave them there, but disabled.

I am trying to find and download the EclipseMercurial plugin for Spring Tools, but every place I look I can't seem to find a way to download it.
The market place won't work and seems like every updated link I find for it is gone now.
On the market page, a guy is saying that the current place for the plugin is here and the update site.
Is this one a working solution or buggy too ?
I have managed to download and install MercurialEclipse using the following link:
https://foss.heptapod.net/mercurial/mercurialeclipse-updatesite/-/raw/branch/default
In Eclipse do the following:
Window->Install New Software
Paste the given link in "Work with" section and hit enter
Select "MercurialEclipse Stable Releases" and hit next
Click agree to the terms and conditions, it might ask you if you really wanna install and just click "Install anyway"
I have had this problems for a couple of times but usually could solve it by an update. However, this fix does not work for me anymore.
Actually, two problems here:
The minor one: I have osX 10.8.3 and Eclipse Juno (M20130204-1200) installed. Since a good amount of time, it takes eclipse ~ 4-5 minutes to start up for the first time after the system start. Once it was closed and is re-opend again, it starts up quick. I think this problem came since apple started to mess around with the JRE? Does anybody also experienced this delay? Could it be that one of the installed plugins checks for updates and causes the delay?
The major one: after eclipse is fully up & running, I can not open .py files anymore. When I open my pydev project (btw. pydev 2.7.3), eclipse freezes and I need to kill the whole thing and restart. -> I can not use it for python coding anymore, which is my primary task...
Suggestions? Re-install eclipse maybe?
Thank you for suggestions,
El
Can't really comment on #1, but for #2, can you try attaching jvisualvm to see what's going on there? (and create a thread-dump and post it somewhere so that I can take a look at it).
I'd ask you to create a bug-report for that, but the new tracker is still not up (I hope I'm able to put it up right after the funding at http://igg.me/at/liclipse is finished).
The problem was resolved by following these steps. They essentially disable one

I'm using PyDev in Eclipse as my Python editor. It's fine in terms of feature set. Everything works fine except for one very annoying thing:
Code completion itself works fast. When I press Alt+Space, the window pops out almost instantly and all the options are there. The option at the top is selected. Then comes the trouble. The detailed description won't appear until about 5-10 seconds. All this time CPU is working at maximum load and the interface is not responding. All the processor is consumed by the Eclipse Java process (the spawned Python process seems idle). Then a yellow window pops up, and all it contains is just a Python code of a selected function/variable. All consecutive details are displayed instantly. The procedure repeats when I close the completion window (for example by accepting one of the options and asking for completion again). This drives me crazy.
I've tried so far:
creating a whole new workspace,
creating an Eclipse/PyDev project from scratch,
tweaking JVM to make sure it has loads of memory,
making sure the right JVM is chosen (the latest Oracle JVM available),
making sure Python process communicates freely with the Java instance (I read about possible problems with that, but it seems not to be the issue).
making sure all the installed plugins are up to date.
The version I use is Eclipse Helios, because the last time I checked certain extensions weren't yet ported to the latest one.
Has anyone observed a similar issue? Was anyone able to get around it? General ideas on how to debug it and file a sensible bug report possibly? Other things worth checking for.
Any workaround less drastic than turning completion off completly?
Thanks!
EDIT:
I've also noticed a problem with a similar popup window in HTML/CSS editor. It looked somewhat similar (a yellow window, with some text inside) and it also took ages to display. Don't really know if that is related, but could be.
EDIT(2):
Ok, No I've started with a fresh install of the newest Eclipse Indigo, without any additional plugins apart from PyDev and the issue remains. Seems like I'll have to look for a new IDE.
What version of Java are you using?
If you are on Windows 7, later versions of Java (I think 6+) will default to IPv6.
This is probably causing the problem as Python maybe wanting IPv4.
Anyway, since I had this problem I tried disabling
PyLint
Code Analysis
but it was still hanging.
Pal's answer about "ipv4 utilization" triggered my memory about another problem I had solved by "preferring" IPv4.
See http://docs.oracle.com/javase/1.4.2/docs/guide/net/ipv6_guide/
What you want to do is to edit your eclipse.ini and add "-Djava.net.preferIPv4Stack=true" in the vmargs section
-startup
plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar
...
-vmargs
-...
-Djava.net.preferIPv4Stack=true
...
I no longer get hangs.
Is there any chance you can provide the code that's making that happen (and add it to a bug report see: http://pydev.org/about.html for links)?
I use PyDev daily with some very large projects and don't have that problem, so, it may be some specific construct or scenario in your code -- or maybe you just haven't given Eclipse enough memory (which would make the garbage collector work much more), in which case, take a look at: What are the best JVM settings for Eclipse? (in specific, raise your -Xmx flag, although you can probably use the other tips there too).
If you can't provide a reproducible scenario, the other choice would be getting a profiler (i.e.: YourKit java profiler has a 15 days free which would help in this case), running that use-case in the profiler and passing a snapshot of what's happening in this situation (if that's the case, please open a bug report at pydev.org and I can help you there).
I got this from pydev.org FAQs and it works fine for me.
When I do a code-completion, PyDev hangs, what can I do?
PyDev does most of its things in the java side, but some information can only be gotten from the python side (mainly builtins), so, in order to get that info, PyDev creates a shell and communicates with it through sockets.
The main problems when that happens are:
There's a firewall blocking the communication to the shell
In Linux, some kernels do not allow ipv4 utilization, which may make PyDev fail.
To enable it, do: echo 0 > /proc/sys/net/ipv6/bindv6only
The timeout to connect is too smal.
It depends upon the "Timeout to connect to shell" in the code-completion preferences (window > preferences > PyDev > Code completion)
If nothing works, please report a bug (also, check if there is anything on the error log (window > show view > PDE Runtime > Error log) and on the eclipse '.log', which is located at the .metadata folder of the workspace location.
Today I tried to download EGit plug-in from eclipse.org, and waited an hour and nothing happened. I tried three more times, waited for three hours and stopped.
Then I tried to clone egit from the repository developers, but it began to clone at a rate of 5kbps.
Then I thought maybe something wrong with my Eclipse, and decided to download a new one. Eclipse main site opened with a super-slow speed (although bigger than 5kbps). I'm just afraid to download the installer at this speed.
Can anybody repoduce it? What should I do?
You're right, Eclipse updating can be horribly slow, regardless of connection speed.
From what I can tell, this is because it checks a whole bunch of slow servers looking for updates every time you try and install something. You can disable this behaviour in the "Install New Software" dialog by unchecking the "Contact all update sites" option. I find that things go an awful lot faster then.
I am exepriencing the same problem. I am developing a plug-in that depends on a feature on the eclipse site. The downloading of that feature takes sometimes up to 30 minutes, even though it is quite small.
This is probably based on eclipse servers which we can't influence. There are a couple bugs opened for this or similar issues. Feel free to comment on them to maybe get them fixed:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=331634
https://bugs.eclipse.org/bugs/show_bug.cgi?id=162101
https://bugs.eclipse.org/bugs/show_bug.cgi?id=189380
and so on .. there are a bunch of those.
Check your firewall. In my case disabling McAfee made it run smooth again.
I found some invalid links in Install/Update under Preferences, basically if you have any sort of invalid links which you may have added trusting in them to be update sites, it causes all downloads to be terribly slow. Go to Preferences>Install/Update and delete all your custom links that you added, you can specifically check the error log to tell you which links are invalid by running Update.
I asked a couple of coworkers about AnkhSVN and neither one of them was happy with it. One of them went as far as saying that AnkhSVN has messed up his devenv several times.
What's your experience with AnkhSVN? I really miss having an IDE integrated source control tool.
Older AnkhSVN (pre 2.0) was very crappy and I was only using it for shiny icons in the solution explorer. I relied on Tortoise for everything except reverts.
The newer Ankh is a complete rewrite (it is now using the Source Control API of the IDE) and looks & works much better. Still, I haven't forced it to any heavy lifting. Icons is enough for me.
The only gripe I have with 2.0 is the fact that it slaps its footprint to .sln files. I always revert them lest they cause problems for co-workers who do not have Ankh installed. I don't know if my fears are groundless or not.
addendum:
I have been using v2.1.7141 a bit more extensively for the last few weeks and here are the new things I have to add:
No ugly crashes that plagued v1.x. Yay!
For some reason, "Show Changes" (diff) windows are limited to only two. Meh.
Diff windows do not allow editing/reverting yet. Boo!
Updates, commits and browsing are MUCH faster than Tortoise. Yay!
All in all, I would not use it standalone, but once you start using it, it becomes an almost indispensable companion to Tortoise.
I always had stability issues with AnkhSVN. I couldn't switch everyone to Subversion where I work without an integrated solution.
Thank goodness for VisualSVN + TortoiseSVN.
VisualSVN isn't free, but it is cheap, and works a treat.
I tried version 1, and it was unreliable to say the least. I can't say anything about 2.0.
If you can afford it, the one I use, VisualSVN, is very good and uses TortoiseSVN for all its gui, except for the specialized things related to its VS integration.
#pilif: AnkhSVN maintains an in-memory state of the working copy, which is invalidated/updated by Visual Studio events (ie you edit/change a file) and AnkhSVN events (ie you commit/update/revert/etc)
Whenever the working copy is changed from outside Visual Studio (by editing with another tool, or by using another Subversion client), you will have to refresh AnkhSvn using the Refresh command we provide.
The other thing that happens when you delete a file in a project with TortoiseSvn for example, is that it remains listed in the project file, and you will have to remove it there seperately (and then commit the project file as well).
Copy/Pasting parts of my own Blogpost, as I switched from Ankh to VisualSVN:
Why did I switch? Because i was a bit unhappy with the overall stability of Ankh, since it has some problems actually tracking Solution changes. VisualSVN is “just” a TortoiseSVN Frontend, which means it leaves all the “heavy lifting” to a third-party tool that a) is installed on most Workstations anyway and b) that’s been tested and used by such a wide audience, it’s really rock-solid.
Now, AnkhSVN is certainly not a bad product, and the people behind it are serious about what they are doing, but having long-deleted files still in my SVN or getting the “Please Cleanup your solution” message get’s annoying after some time, but my biggest gripe is the property window. It’s nice that there is a nice window with Radio Buttons asking me which property I want to add. Unfortunately, there is no way to manually enter a property.
Edit: That was for AnkhSVN 1.x. In the meantime, it was updated to 2.x and much improved. I use it in production on a system where I don't have VisualSVN and it works extremely well now.
I had no problems with v1, but I was warned not to use it. I've been using v2 for a while, and I've had no problems with it. I still keep a backup of the repository though...
I started with AnkhSvn and then moved on to VisualSvn. I have my own gripes with VisualSvn but its far less trouble compared to Ankh. I'm yet to try the new version of Ankh which they say is a complete rewrite and had inputs from Microsoft dev team as well.
I've been using both the newest version of Ankh SVN and Tortoise on a project at home. I find them to both be very good with a caveat.
I've found that both SVN tools have at times failed to keep up with my file/folder renaming and moving resulting in it thinking that a perfectly good file needs to be deleted on the next commit. This is probably down to me misusing SVN in some way but TFS at work does not have this problem.
I tried AnkhSVN (1.0.3, just 4 months ago), and it did not work the way I wanted it to (i.e. needed to select things in the browser window instead of based on active file). I ended up making some macros that utilize TortoiseSVN that work much more like what I expected.
I've been very happy with using TortoiseSVN via explorer and my macros inside the IDE.
Earlier on (like 2 years ago when I last tried), AnkhSVN and Tortoise used in parallel with the same working copy caused some kind of working copy corruption where Ankh and Tortoise somehow lost track of the state the other tool left the working copy in.
It was as if one of the tools stored additional metadata not contained in the working copy and was reliant on that being correct.
The problems showed themselves by Ankh (or Tortoise) insisting on files being there which weren't, on files being changed which weren't and on files not being changed which were (and thus unable to commit).
Maybe this has been fixed since, but I thought I'd better warn you guys.
About a year ago me and a buddy used AnkhSVN for a project... several commits later while moving namespaces around, it broke the SVN repository. Broke as in, the last commit we did got corrupted, and we couldn't commit anymore.
After that we used TortoiseSVN and did the namespace moving manually, it just... worked. If you're only working on base class libraries you could always try using SharpDevelop instead (that integrates with TortoiseSVN).
I do hope they did fix AnkhSVN now though because IDE integrations always rock... when they work.

I've found that both SVN tools have at times failed to keep up with my file/folder renaming and moving resulting in it thinking that a perfectly good file needs to be deleted on the next commit.
A move or rename operation results in an delete and 'add with history' at subversion level.
TortoiseSvn shows this as:
originalFile deleted
newFile added (+)
