Production release date¶
2014.08.22
New¶
- allow views to use their previous value as part of their recalc.
- views, in addition to vars, are now also returned by default HTTP handler.
- removed limit on number of concurrent vectors which can have
`g
attr. \c
– Console width, height now defaults to 100 1000, previously was 25 80;LINES
,COLUMNS
environment vars override it.- allow some messaging threads other than main.
- retain
`p
attr if both args to catenate have`p
attr, and parted info conforms - map single splayed files.
- appending a sorted vector to a sorted vector on disk now just appends to the file if the sort can be retained.
exec by a,b
orselect by a,b
now sets sort/part attr for those cols. Enhancement to that released on 2014.02.07, now multiple cols- Support automatic WebSockets compression according to (https://tools.ietf.org/html/draft-ietf-hybi-permessage-compression-17)
- added
dsave

and save; expectssym
as first col. rload
changed to map all singleton splayed tables; eliminates all the open, map, unmap, close overhead.- expanded mlim (number of mapped nested files) from 251 to 32767.
- Added WebSocket client functionality.
.z.ws
must be defined before opening a WebSocket - allow single escape
\
for\/
in char vector (to support JSON) - JSON [de]serialization is now part of
q.k
- uses two file descriptors per compressed file. This is a result of the change in design to accommodate decompressing a file from multiple threads
Not upwardly compatible¶
- views cannot be triggered for recalc from socket threads – signals
'threadview
. - view loop detection is no longer performed during view creation; now is during the view recalc.
var
,dev
,cov
,cor
andenlist
are now reserved words.`g
attr can be set on a vector in main thread only.
