f707783aba Remove old methods of triggering doc updates 
Remove the old pub/sub listener which is no longer used.

Also remove the DocsWithPendingUpdates set, which used to track
docs waiting to be updated. This was necessary incase messages were
missed on the pub/sub channel, so we knew which docs still had pending
updates. However, now we use the BLPOP queue, these updates just sit in
the queue until a consumer comes back to continue consuming them.

d27d2b90a2 Merge pull request #5 from sharelatex/utf16_fix 
Replace UTF-16 surrogate characters with 'replacement character'
 2015-06-12 10:18:34 +01:00
James Allen
a3847d21d5 Replace UTF-16 surrogate characters with 'replacement character' 
In Javascript, characters are 16-bits wide. It does not understand surrogates as characters.

From Wikipedia (http://en.wikipedia.org/wiki/Plane_(Unicode)#Basic_Multilingual_Plane):
"The High Surrogates (U+D800–U+DBFF) and Low Surrogate (U+DC00–U+DFFF) codes are reserved
for encoding non-BMP characters in UTF-16 by using a pair of 16-bit codes: one High Surrogate
and one Low Surrogate. A single surrogate code point will never be assigned a character.""

The main offender seems to be \uD835 as a stand alone character, which would be the first
16-bit character of a blackboard bold character (http://www.fileformat.info/info/unicode/char/1d400/index.htm).
Something must be going on client side that is screwing up the encoding and splitting the
two 16-bit characters so that \uD835 is standalone.

ffd10a8439 Don't send or get versioning info to/from web 
The version number is only used by the doc updater and so can be cleanly
encapsulated in a collection that only the doc updater knows about. The version
is already stored under docOps, so continue to tore it there.
