Description

The goal of this project is to accomplish tasks that facilitate dgp's continued efforts to improve Tcl. The project will run for a minimum of 30 days and will continue as long as there is sufficient funding and available resources. The work queue will be curated directly or indirectly by dgp. Coordination and communication will occur primarily in the Tcl Chatroom.

Funding will be solicited from individuals and other entities with an interest in Tcl.

APN I'm all for this project but sadly, can only offer moral, not financial, support! Good luck with getting the backing.

Completed

Fix errors in async.test under valgrind: Valgrind slows things down enough that previous assumptions about time to completion are rendered false.

Reference counting for ItclMemberCode: Similar changes were already applied for ItclObject. The larger goal is to address performance issues mentioned issue 271 .

Added a gdb-test target to SampleExtension: For more convenient debugging.

Fix valgrind target in SampleExtension: TCLLIBPATH` was not being set so there was a risk of picking up a previously-installed shared object.

TIP 498 , Fix memory leak due to reference counting error

TIP 498 , Move refCount management of lookupNsPtr out of "resolve:/goto resolve" block

TIP 498 , Fix reference counting error in TclRenameCommand

TIP 498 , Fix memory leak in Tcl_DeleteNamespace

Deduplicate code in string comparison functions: Also avoid generating the string representation of pure lists and dictionaries when comparing with the empty string.

Fix memory leak in epoll: Cleanup the eventfd trigger file info created during initialization.

Waiting

trace: Improve error handling and resolve other known issues.
array: Redesign machinery to support array for and array searches

: c.f. http://core.tcl.tk/tcl/info/e87bcf819f03cea4

Tk: Modify to use interface of TIP 445 , or demonstrate deficiencies in that TIP.
info variable introspection gap :
aspect-string-match : complete the work started by aspect to streamline and deduplicate string matching routines.

Proposed

TDBC::ODBC: Revise to support systems with 32-bit SQLWCHAR. See the androwish fork .
TDBC::sqlite: Reduce memory consumption for large result sets
TDBC::sqlite: Resolve known issues regarding duplicate column names in results
TDBC: Move looping constructs down into C.
Deduplicate code in string matching functions. In the same area see ticket Exponential complexity for bad patterns instead of linear .

SYStems 2018-05-07: Can we add a Tcl/Tk modern IDE to that list :)

ak I believe that one is a step to far and big.

SYStems let's do it then :)

APN One performance enhancement I would like, if you are taking RFE's, is faster calls to commands implemented in C extensions. They are currently significantly slower than bytecoded commands.
