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) == N) N <- 5 * N else break } close(pngfile) #There is a table df_DemandPatternMaster in the database with primary...

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 ...

v1 -> v2: - Remove the unnecessary calls to guestfs_int_lazy_make_tmpdir in the final patch. Rich.

Miscellaneous small cleanups in lib/ directory. Rich.

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:

...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 th...
