Mercurial allows for tying in keyring configuration for those of us who do not want to store passwords in plain-text in our
.hgrc files or constantly using SSH.
First install the Python keyring library by running
pip install keyring. After that is installed, checkout https://bitbucket.org/Mekk/mercurial_keyring/ and add to
$HOME/.hgrc the following:
mercurial_keyring = ~/path/to/mercurial_keyring/mercurial_keyring.py
Next up, configure your repositories, e.g. in the case of Bitbucket I use:
bitbucket.prefix = bitbucket.org/asmodai
bitbucket.username = asmodai
bitbucket.schemes = https
Mercurial keyring will automatically decide on the best keyring to use. On a FreeBSD system with no Gnome or other systems providing a keyring, if you do not specify a specific keyring, the system will use the file
~/.local/share/python_keyring/keyring_pass.cfg. This keyring file stores the passwords encoded in Base64 in plain-text. This is not quite what you would want from a security point of view. You can configure which backend store to use by editing
~/.local/share/python-keyring/keyringrc.cfg. To get a plain-text file with encrypted keys use the following configuration:
This will create the file
~/.local/share/python-keyring/crypted_pass.cfg after initializing the backend store with a password. Look at the documentation for keyring on what other configuration options are available.
Note: make sure the PyCrypto dependency is installed with the
_fastmath module. This in turn depends on the
If you have a Subversion repository setup with multiple top-level projects and their typical branches/tags/trunk setup and want to migrate these to individual Mercurial (Hg) repositories, you can do this with the convert extension.
First you need to enable convert in your
.hgrc by adding a section like the following:
Next, if needed, create a plain-text file, e.g. author-map.txt, containing SVN username to Hg author mappings, e.g.
asmodai=Jeroen Ruigrok van der Werven<firstname.lastname@example.org>.
Next run Hg as follows:
hg --authors author-map.txt --config convert.svn.branches=project/branches --config convert.svn.tags=project/tags --config convert.svn.trunk=project/trunk path/to/svn/repository path/to/destination/hg/repository
This will start a SVN to Hg conversion, picking up only the changes and commit messages applicable for the various paths you gave for the branches, tags, and trunk, effectively splitting off this project from the main SVN tree into its own Hg repository.
Do note that for large SVN repositories this might not be the most efficient conversion way forward. In that case converting once from SVN to Hg and then split off Hg into many Hg repositories might be faster. Will adjust this post when I write that up.
Just received my Android 4.0 UI stencil from UI Stencils. I love how it works, makes UI prototyping for Android much nicer when drawing out using pen and paper. I recommend it.
I was playing around with Eclipse and TestNG, the thing you need/want to do is, after you have installed testng via de Eclipse market place and restart Eclipse to go to the project build path.
So right click the project and select from the popup menu
Build Path » Configure Build Path...
In this window, make sure you have selected the
Libraries tab in the right-hand side of the window.
Add Library... and from the resulting window that pops up select TestNG (or JUnit).
When you select
Finish (depending whether you picked TestNG or JUnit), you will then see TestNG under the JRE System Library entry as another library entry. If you expand this you see the
testng.jar being included and pointing to the right jar file that’s in Eclipse’s plugins directory.
When you now press
OK you should see the imports getting resolved.
You will need to remove any external jar dependencies for TestNG or JUnit of course, because it’s double and will most likely lead to problems.
Now, when you go to
Run » Run Configurations... you see a
TestNG (JUnit) entry. When you select that entry and create a new configuration underneath it, it should already resolve everything you need (classes, packages, and so on).
Oh, do keep in mind that you will have to mark the
test folder as a source folder for it all to work. Right click the folder, select
Build Path » Use as Source Folder.
Having resolved recent SSL certificate issues with Mercurial/TortoiseHG, I now encountered a similar issue with the wildcard certificate for
*.google.com where getting a clone would result in a
"SSL: Server certificate verify failed" error.
One way around this issue is to add the fingerprint for this certificate to your configuration. Currently for
*.google.com this is
00:d5:88:35:29:b9:7f:03:92:60:c2:04:e4:b7:01:f0:07:53:15:a8 and one way to get this from a Unix command line is with
openssl s_client -connect code.google.com:443 < /dev/null 2> /dev/null | openssl x509 -in cert-code -fingerprint -noout -in /dev/stdin | tr "[:upper:]" "[:lower:]". This corresponds with Chrome’s certificate view’s thumbprint field, you just need to add colons.
Right click in Explorer, select
TortoiseHG » Global Settings and then click
Edit File and add the following:
code.google.com = 00:d5:88:35:29:b9:7f:03:92:60:c2:04:e4:b7:01:f0:07:53:15:a8
This should make Mercurial/TortoiseHG work, at least until the certificate expires and you need to update it with the latest fingerprint.
For my own development I use Mercurial and TortoiseHG for my version control system. I also use, at the moment, a CAcert certificate to use HTTPS with my repositories. I am not sure what changed when, but apparently the certificates now get verified. So this causes obvious problems trying to push or pull due to
"SSL: Server certificate verify failed" errors.
To make this work on a Windows 7 machine with TortoiseHG in stalled, first download the CAcert root PEM certificate and place it some permanent directory. Next open the TortoiseHG global settings (right click somewhere in Explorer and select
TortoiseHG » Global Settings). In the window that opens click the Edit File button. If it does not exist yet create a section similar to this:
cacerts = C:\path\to\cacert-root.pem
OK and any push and pull action with HTTPS URLs should work as they ought to.
After upgrading various ports on my FreeBSD system and days later a full world and kernel, a reboot showed me that unbound didn’t start. The system reported that:
error: reading root hints
/usr/local/etc/unbound/named.cache 88: Empty line was returned
It turns out that from ldns 1.6.13 to 1.6.14 there is an API change that caused problems for unbound. After upgrading ldns you also need to recompile unbound to pick up on these changes. If you do not, you will run into the problem above.
I am really impressed with pkgng. On the mebsd website there’s a handy explanation and tutorial that’s really worth reading to get up to speed.
If you try to use the PS Vita’s Near funcitonality over WiFi and get “Location data cannot be obtained” constantly, try to turn off the Vita completely (hold the power button at the top for a few seconds) and then turn it on again. This at least solved it for my PS Vita.
If, like me, you had a working FreeBSD system with amavisd-new and p0f set up, you might find that p0f suddenly stopped working at some point. The cause for this is that it tries to use pcap on the USB bus, which it cannot do. The solution is to put
hw.usb.no_pf=1 in your
