making changes to global variables in functions
I'm trying to write a function that takes several objects with many different attributes and then changes their attributes. So what I wanted to happen in the simplified example below is for the function to change the attributes of the objects state1 and state2 that are passed to it. But because stateA and stateB are local, this isn't working. Are there any easy solutions? e.g., if I could

Restful Authentication and State Machine state transfer question
I''m adding some code to a project using restful_authentication and acts_as_statemachine In the create method for a user there is the following code generated by the restful_authentication template @user.regster! if user.valid? And this will save and the user record if it is valid. I understand that the statemachine will then change the state from passive to pending. It will guard

State machines and parsing texts
Hi, although my question is not just rails specific, I think it fits this discussion more than the ruby discussion. I found a state machine package very useful (http:// statemachine.rubyforge.org/). I do not know any alternatives for this. Do you have any tips which one could be an interesting alternative? I used the mentioned state machine for parsing of text, which although has structure, but

[libnbd PATCH 0/3] opt_list_meta_context
I'm posting this now, as I'm at the end of a workday and I got things working for manual experimentation. Still to do: - write interop tests for qemu-nbd and nbdkit (including my proposed patch addition of qemu-nbd -A to show qemu:allocation-depth) - figure out if we can make 'nbdinfo --map' use the new API to automatically select all contexts advertised by the server Eric Blake

[libnbd PATCH 0/3] Expose server block size constraints
Necessary when writing a client that wants to avoid unnecessary EINVAL errors from sending unaligned requests. At some point, we may want to add synchronous convenience API wrappers that do request splitting or read-modify-write to obey server constraints while still appearing to the library client as accepting any possible request. But such a wrapper should only be synchronous and not copied to

[libnbd PATCH 0/2] fix hangs against nbdkit 1.2
nbdkit 1.2 as a server waits for read() to see EOF, even after the client has sent NBD_CMD_DISC. That was fixed in mbdkit 1.4; and most modern NBD servers are smarter than this (they close() the write end of their traffic soon after NBD_CMD_DISC). But it's easy enough to revert nbdkit commit c70616f8 to get back to a server with the same behavior as the older nbdkit, at which point both

[PATCH libnbd PROPOSAL] Add APIs for listing exports from an NBD server.
Proposal for new APIs to list exports. The general shape of the API can probably best be seen from the examples/list-exports.c example. Rich.

[libnbd PATCH v2 00/13] Adding nbd_set_opt_mode to improve nbdinfo
Well, I'm not quite done (I still want to get nbdinfo to work on a single nbd connection for all cases when reading the heads of the file is not required), but I'm happy with patches 1-11, and 12-13 show where I'm headed for getting NBD_OPT_INFO to work. Posting now to see if some of the earlier patches are ready to commit while I continue working on the latter half. Eric Blake (13):

[libnbd PATCH v4 0/4] Saner reply header layout
This was v3 patch 2/22, reworked to address the confusion about how a structured reply header is read in two pieces before getting to the payload portion. I'm still working on rebasing the rest of my v3 series (patches 1, 3-22) from other comments given, but this seemed independent enough that it's worth posting now rather than holding it up for the rest of the series.

[PATCH libnbd 0/2] api: Add support for AF_VSOCK.
This is a series of patches to libnbd and nbdkit adding AF_VSOCK support. On the host side it allows you to start an nbdkit instance which listens on a virtio-vsock socket: $ ./nbdkit -fv --vsock memory 1G ... nbdkit: debug: bound to vsock 2:10809 On the guest side you can then use libnbd to connect to the server: $ ./run nbdsh -c 'h.connect_vsock(2, 10809)' -c

[libnbd PATCH] API: Add nbd_set_opt_mode to expose NEGOTIATING state
This is the bare minimum needed to allow the user to take control over the rest of option negotiating. This patch adds several new API: nbd_set_opt_mode() - called during Created to enable the new mode nbd_get_opt_mode() - query whether opt mode is enabled nbd_opt_go() - used in Negotiating state to attempt to use export nbd_opt_abort() - used in Negotiating state to skip Connected state

[libnbd PATCH v3 0/2] Implementing NBD_OPT_LIST
This is a subset of my v2 posting, but limited to just the NBD_OPT_LIST handling. The biggest change since v2 is the addition of added unit testing in all four language bindings (C, python, ocaml, golang). The tests require nbdkit built from git on PATH, and may not be entirely idiomatic, but I at least validated that they catch issues (for example, adding an exit statement near the end of the

[PATCH libnbd 0/5] info: --map: Coalesce adjacent extents of the same type.
This adds coalescing of adjacent extents of the same type, as mentioned by Eric Blake in the commit message here: https://github.com/libguestfs/libnbd/commit/46072f6611f80245846a445766da071e457b00cd The patch series is rather long because it detours through adding the <vector.h> library from nbdkit into libnbd and replacing ad hoc uses of realloc, char ** etc in various places. Rich.
