Storage

  • Resolved an issue when attempting to migrate HDB data to Azure Blob Storage. Previously, this would fail with a signature error.

REST Server

4.0.2

Release Date

2023.03.16

Improvements

[NEW] Implementation of retries for generating new access tokens and increased default duration of token validity for object storage. There are now perpetual internal retries with exponential backoff for token refresh to prevent access loss, and configuration has been updated to increase KX_KURL_AWS_TOKEN_DURATION from a default of 900 seconds to 3600 seconds to reduce the frequency of requests.

For GCP/Azure and OAuth2 support, the session duration is not configurable on the client side, and must be configured in Google Cloud or Azure.

4.0.1

Release Date

2023.01.23

New features

[NEW] function .Q.ld exposes logic used by \l to group script lines for evaluation.

q).Q.ld read0`:funcs.q
1                   2                5                    6
"/ multi line func" "f:{\n  x+y\n }" "/ single line func" "g:{x*y}"

[NEW] -p cmd line option (or \p system command) can now listen on a port within a specified range e.g.

q)\p 80/85
q)\p
81

The range of ports is inclusive and tried in a random order. A service name can be used instead of a port number. The existing option of using 0W to choose a free ephemeral port can be more efficient (where suitable). Range can be used in place of port number, when using existing rules e.g. for hostname.

q)\p myhost:2000/2010
// or for multithreaded port
q)\p -2000/2010

[NEW] x) will try to load x.k_ if loading x.k fails

[FIX] The debugger could return incorrect line numbers for multi-line functions containing multi-line comments.

[FIX] Reading with 1: no longer strips quotes, e.g. ("abcd";"\"ef\"")~first each("**";4 4)1:"abcd\"ef\""

[FIX] Windows will now pick up versions of openssl prior to v3.
