similar to: Proposed new libguestfs file APIS

These APIs provide handle-based read/write streaming and random access to files and block devices. --- daemon/.gitignore | 1 + daemon/Makefile.am | 1 + daemon/hfile.c | 196 +++++++++++++++++++++++++++++++++++++++++++++ daemon/m4/gnulib-cache.m4 | 3 +- po/POTFILES.in | 2 + regressions/Makefile.am | 1 + regressions/test-hfile.pl | 102

This patch changes pwrite such that it will never return a short write. This is a backwards compatible API change, as checking for short writes remains correct, but redundant. --- daemon/file.c | 20 +++++++++++++------- src/generator.ml | 6 ------ 2 files changed, 13 insertions(+), 13 deletions(-) diff --git a/daemon/file.c b/daemon/file.c index da899b6..9ce0783 100644 ---

Recently there was a question on using lme with large data sets. As an experiment I fit a linear mixed-effects model to a data set with about 350,000 observations on 6 predictors, a numerical response, and a single grouping factor. The timings shown below were on a 1.2 GHz Athlon with 1 GB of PC133 memory and 2 GB of swap. The operating system is Debian 3.0 GNU/Linux. The kernel is 2.4.14.

This follows (tails) a log file within a guest, rather like the regular 'tail -f' command. For example: virt-tail -d guest /var/log/messages --- .gitignore | 3 + bash/Makefile.am | 4 +- bash/virt-alignment-scan | 6 + cat/Makefile.am | 47 ++++- cat/tail.c | 498 +++++++++++++++++++++++++++++++++++++++++++++++ cat/test-docs.sh

Previously we had lots of types like String, Device, StringList, DeviceList, etc. where Device was just a String with magical properties (but only inside the daemon), and DeviceList was just a list of Device strings. Replace these with some simple top-level types: String StringList and move the magic into a subtype. The change is mechanical, for example: old

Done using a sequence of regular expressions like this: perl -pi.bak -e 's{C</}{F</}g' `git ls-files \*.pod` generator/actions.ml perl -pi.bak -e 's{C<C:\\}{F<C:\\}g' `git ls-files \*.pod` generator/actions.ml [etc] and then tediously checking every change by hand. --- align/virt-alignment-scan.pod | 8 +-
