A new entry in the annals of unfortunate software release dates:
On August 19, Valgrind 3.5.0 was released. It added support for Mac OS 10.5.
On August 28, Mac OS 10.6 was released.
Valgrind 3.5.0 does not support Mac OS 10.6.
If you try to install Valgrind on a machine running Mac OS 10.6, it will fail at configure-time. [...]

Valgrind 3.5.0 has been released! It’s the first release that supports Mac OS X. It also adds a number of other new features and a whole lot of bug-fixes. See the release notes for details. Many thanks to everyone who contributed to this release.

We’re now in the preparation phase for the 3.5.0 release of Valgrind, which will be the first release with Mac OS X support. We’ve absorbed some Mozilla culture in the Valgrind development process — we’re now using Bugzilla much more effectively. We have 17 open blockers (and 18 closed blockers), and 41 open “wanted” bugs [...]

It’s time for the June update on the progress of the Mac OS X port of Valgrind.
Progress has been good: the DARWIN branch has been merged to the trunk. With that having happened, we’re now in sight of an actual release (3.5.0) containing Mac OS X support. There’s some polishing and bug-fixing — both [...]

This morning I merged the DARWIN branch, which had been holding Valgrind’s support for Mac OS X, onto the trunk. The branch is now defunct, and Valgrind-on-Mac users should check out the trunk like so:
svn co svn://svn.valgrind.org/valgrind/trunk <dirname>
cd <dirname>
and then build it according to the instructions in the README file.
This is a good thing, [...]

It’s time for the May update on the progress of the Mac OS X port of Valgrind. In the last month, 133 commits have been made to the DARWIN branch by Julian Seward and myself.
Here are the current (as of r9898) values of the metrics I have been using as a means of tracking progress.
The [...]

Now that I’m working for Mozilla, one of my goals is to make Valgrind easier to use on big programs like Firefox. One feature of such programs is that often they create multiple processes. For example, when I invoke ‘firefox’ on my Linux box, I’m really running three programs. /usr/bin/firefox is a [...]

It’s time for the April update on the progress of the Mac OS X port of Valgrind. It’s been a quieter month because I was on vacation for over 3 weeks, and Julian Seward hasn’t had a great deal of time to work on the port either. Even still, in that time 77 commits have [...]

Another month has passed since I last wrote about my work on the Mac OS X port of Valgrind. In that time 126 commits have been made to the DARWIN branch (and a similar number to the trunk). I’ve done a lot of them, but Julian Seward has found some time to work on the [...]

Here’s what sounds like a simple question: in C, what’s the best way to convert a string representing an integer to an integer?
The good way
One way is to use the standard library function called strtol(). There are a number of similar functions, such as strtoll() (convert to a long long) and strtod (convert to a [...]
