Welcome to the ncbi-vdb wiki!

ANNOUNCEMENTS:

February 10, 2022

NCBI’s SRA changed the source build system to use CMake in toolkit release 3.0.0. This change is an important step to improve developers’ productivity as it provides unified cross platform access to support multiple build systems. This change affects developers building NCBI SRA tools from source. Old makefiles and build systems will no longer be supported after we make this change.

This change also includes the structure of GitHub repositories, which underwent consolidation to provide an easier environment for building tools and libraries (NGS libs and dependencies are consolidated). Consolidation of NGS libraries and dependencies provides better usage scope isolation and makes building more straightforward.

Affected repositories

1. ncbi/ngs (https://github.com/ncbi/ngs)

   This repository will be frozen, and all the code moved to Github repository ncbi/sra-tools, under subdirectory ngs/. All future modifications
   will take place in sra-tools

2. ncbi/ncbi-vdb (https://github.com/ncbi/ncbi-vdb)

   This project’s build system will be based on CMake. The libraries supporting access to VDB data via NGS API will be moved to Github repository ncbi/sra-tools.

The projects to move are:

Old location (base URL: https://github.com/ncbi/ncbi-vdb)	New location (base URL: https://github.com/ncbi/sra-tools)
libs/ngs	ngs/ncbi/ngs
libs/ngs-c++	ngs/ncbi/ngs-c++
libs/ngs-jni	ngs/ncbi/ngs-jni
libs/ngs-py	ngs/ncbi/ngs-py
libs/vdb-sqlite	libs/vdb-sqlite
test/ngs-java	test/ngs-java
test/ngs-python	test/ngs-python

3. ncbi/sra-tools (https://github.com/ncbi/sra-tools)

   This project’s build system will be based on CMake. The project will acquire some new components:

   3a) NGS SDK (now under ngs/, formerly in Github repository ncbi/ngs)
   
   3b) NGS-related VDB access libraries and their dependents, formerly in Github repository ncbi/ncbi-vdb, as listed in the table above.
   

ATTENTION:

VDB has transitioned to all HTTPS access as of October 7, 2016 with release 2.8.0. It is critically important that you update all of your binaries and your configuration files.

This is in response to OMB memorandum M-15-13 issued on June 8, 2015, requiring all Federal HTTP servers to stop using (simple) HTTP and switch to HTTPS.

Please update your software as soon possible to give some time to ensure continued operation.

Proxy users take note - this complicates proxy usage somewhat. We will create a Wiki page dedicated to supported proxy configuration and firewall settings to help users during the conversion.
