Issue

On Mac OS X Lion (64bits at least), we get random "Bus error 10" (or "Segmentation fault: 11") crashes if init:restart/0 is called and the crypto application is loaded. Why? XCode 4.1 ships an OpenSSL version that deprecates many functions used by OTP's crypto NIF (lib/crypto/c_src/crypto.c).

Example:

Your API does REST, but can it SLEEP?

SLEEP (Syncable Lightweight Event Emitting Persistence) is an emerging standard for distributed data sync using HTTP and JSON. A generalized version of CouchDB's much lauded built-in replication, SLEEP extends the REST architecture to define a way in which databases can offer syncable JSON APIs that foster open data innovation by allowing developers to replicate entire databases over the net.

---

SLEEP comes from the Apache CouchDB project which is now widely known for it's multi-master streaming HTTP + JSON replication. This is possible in part because of the CouchDB _changes feed, which is a particular API that lets you see if there have been any changes made to the database since last time you synchronized. CouchDB can efficiently implement the _changes feed because of one subtle difference between it and most other databases: it stores a history of all changes that happen to the database, including deletes.

If you synchronize data from a remote source and then the

Hi devs,

Over the last two years we've discussed improving our documentation, website, and wiki. We have discussed several designs ad mortem[1]…[5], and while the wiki has evolved substantially, not much else has changed.

This proposal summarises a consensus direction, and puts forward an approach that should allow us to improve docs in incremental stages with the usual peer review process for the actual patches/changes.

Conflict winners are chosen dynamically, every time a request for the document arrives. The revision tree is sort of like a git repository: most updates are based on a parent update. In general, you have a tree of changes, but usually it works out to a linear linked list.

Anyway, the winner is the version with the longest revision history. (That is arbitrary but deterministic, so two couches with the same revision trees will pick the same winner.)

couch_doc:to_doc_info_path does the main job: converting the revision tree into an array of paths from root to leaf. It returns this array sorted, with the longest path first. The diff here will print a log message every time the comparison function is called by lists:sort().

The execution path basically goes:

1. couch_http_db:db_doc_req()
2. couch_db:open_doc()

Punctuation: who cares?

Punctuation is a bikeshed. Put your semicolons, whitespace, and commas where you like them.
