...only been insisting on the looser notion of a matching ._api_version, which doesn't help when we've forgotten to bump that macro when making incompatible API/ABI changes (see commit 6934d4c1). However, we can't use .version (it was documented as optional, so even though all our in-tree filters set it, a theoretical out-of-tree filter could use NULL; and it has changed offsets in the ABI during previous API changes, such as commit ee61d232). Thus, we have to bump the API version one final time; but now, our API guaarantees enough stable ABI to check the version string as part of our API...

...'m inclined to instead squash it into patch 1. This patch is written to apply after my NBD_CMD_CACHE work (since I touched the nocache filter); but can be rearranged if we think this series should go in first while that one undergoes any adjustments from review.

No need for filters to specify their model in two different ways; the callback alone is sufficient. Since all filters are in-tree, we can deal with the API/ABI change made here.

Similar to the existing fua, nozero and noextents filters, add a filter to make it easy to override the basic caching functionality, in part to facilitate timing tests of whether a plugin's cache implementation is worthwhile. A worthwhile test to add to the testsuite would connect the log filter both before and after the nocache filter, to prove how...

When using a filter that rounds up to alignment boundaries, the tail bytes of the plugin are difficult to access correctly. Rather than duplicating lots of code already in the truncate filter, it's easier to just make the other filters default to rounding down and add doc links on how to round up instead.

Hi, I'm a R newbie and want to accelerate the following pre-filtering step of a data set with more than 115,000 rows : #----------------- # Function to filter out constant data columns filter.const<-function(X, vectors=c('column', 'row'), tol=0){ realdata=c() filteredX<-matrix() if( vectors[1] == 'row' ){ for( row in (1:nrow(X)) ){ if(

...uninitialized data from the heap, or even leak it back out to the file system through the plugin or the NBD client. The quickest fix is to just always round down, and then do a better job of documenting how the user can round up as needed.

This is a second version of the limit filter. v1 was posted here: https://www.redhat.com/archives/libguestfs/2020-March/msg00015.html I didn't bother to repost the other three patches because they are the same. The difference is this version of the filter takes security more seriously. It shouldn't be possible for malicious clients to connect more than limit=N times to the plugin now,

This incomplete patch adds a new filter allowing more control over when nbdkit exits. You can now get nbdkit to exit gracefully on certain events, such as a file being created, a pipe held open by another process going away, or when another PID exits. There is also a script option to allow for completely custom events. It is untested at the moment, I'm posting it to get feedback on the
