Hi, I am creating some graphs which I want to update into a database table. The procedure I am following is: 1. create the graphs as a png/jpeg file. 2. Read that file as a binary vector 3. sqlUpdate My code: pngfile <- file(<filename>, "rb") N <- 1e6 repeat{ pngfilecontents <- readBin(pngfile, what="raw", n=N) if(length(pngfilecontents) ==

There were various places in the library where we open coded making temporary filenames. This uses the utility function instead. --- lib/appliance-uefi.c | 4 +++- lib/command.c | 5 +++-- lib/drives.c | 4 +++- lib/inspect-icon.c | 12 +++++++++--- lib/launch-direct.c | 5 ++--- lib/launch-libvirt.c | 5 ++--- lib/launch-uml.c | 5 ++--- 7 files changed, 24

This patch series changes a small part of the library to use __attribute__((cleanup(...))) to automatically free memory when pointers go out of the current scope. In general terms this seems to be a small win although you do have to use it carefully. For functions where you can completely get rid of the "exit code paths", it can simplify things. For a good example, see the

Inspired by libvirt's virCommand* internal mini-library, this adds some internal APIs for running commands. The first patch contains the new APIs. The subsequent patches change various parts of the library over to use it. Rich.

I think this was asked recently but I can't find the item. Is it possible to find the colour at a point on a graphics page? I want to estimate the area of a complex shape by colouring it then random sampling from an enclosing box ...

Commits 3c27f3d91e1566854747bbe844186783fc84f3a8 and 1b6f0daa9ae7fcc94e389232d0c397816cda973d added an internal API for running commands asynchronously. It is only used by the copy-in and copy-out APIs. Unfortunately this made the command code very complex: it was almost impossible to redirect stderr to a file, and there were a lot of long-range dependencies through the file. It was also buggy:

This function returns -1 if things like fork(2) fail, so it is right to return an error here. If the PBMTEXT command fails then that's a NOT_FOUND case. --- lib/inspect-icon.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/lib/inspect-icon.c b/lib/inspect-icon.c index 533e9fb4b..0edd3d1b0 100644 --- a/lib/inspect-icon.c +++ b/lib/inspect-icon.c @@ -400,7 +400,7 @@

Hi, I am using TOMCAT 6.0.14 on Solaris 10 i86. I wrote a perl script which is running a cgi on tomcat, from there i am taking input value's and using the following way to create a graph using R and accessing that graph to attach it on webpage: .... .... my $to_run = "/usr/local/bin/R --vanilla --slave --args $selected_host $graph_start $graph_end < ..\/..\/..\/page\/R\/" .

...ray" and on screen I did not see colors. I put some of the eps files up here, so you can see what I mean: http://lark.cc.ku.edu/~pauljohn/R/epsfiles And if you don't have an eps viewer handy, I made png versions, since all browsers seem to show them. http://lark.cc.ku.edu/~pauljohn/R/pngfiles/ The docs indicate that the x11 device is being copied, but I rather think that a plot object that exists "behind" the x11 device is being saved.? I have since learned that I can put col=c("black") into the matplot command to make sure no colors are used, and that works the...

libguestfs has used double and triple underscores in identifiers. These aren't valid for global names in C++. (http://stackoverflow.com/a/228797) These large but completely mechanical patches change the illegal identifiers to legal ones. Rich.

The Wine development release 1.3.20 is now available. What's new in this release (see below for details): - Option to clip the mouse inside fullscreen windows. - Support for persistent HTTP connections. - Initial implementation of the XML writer. - Support for drawing rectangles in the DIB engine. - Volume control in MMDevAPI. - More MSVC runtime functions. - Various bug fixes.

Because of previous automated commits, such as changing 'guestfs___' -> 'guestfs_int_', several function calls no longer lined up with their parameters, and some lines were too long. The bulk of this commit was done using emacs batch mode and the technique described here: http://www.cslab.pepperdine.edu/warford/BatchIndentationEmacs.html The changes suggested by emacs were
