v1.4.0

c878f90

This release adds a new module input.zmmpcap to read compressed PCAPs using mmap(), changes how core.thread push/pop, removes signal blocking and squashes a few bugs.

For core.thread, the push()/pop() now uses double instead of int64_t to match the conversion table of LuaJIT and to support floating point numbers.

Packages are available at: https://dev.dns-oarc.net/packages/

Updates:

examples/dumpdns:
- Add support for reading PCAPs using mmpcap or zmmpcap
- Add support for reading PCAPs from stdin
zpcap: Add support for reading zlib/lzma compressed PCAPs

Fixes:

Fix #234: Remove signal blocking
Fix #233: floating point numbers not supported by dnsjit.core.thread push/pop
Fix a potential memory leak in trie
zpcap: Fix incorrect check if having enough to read

v1.3.0

03719c6

Release 1.3.0

This release adds core.object.dns:reset() to reset DNS objects so they can be reused correctly.

Example scripts have been updated to reflect this along with correctly setting includes_dnslen for TCP packets.

New example converter pcap2tcpdns added that can be used to create bin files for replaying with dnsperf -B.

v1.2.0

b340067

Release 1.2.0

This release adds development files and autotool examples for C/Lua modules or stand-alone tools for dnsjit.

Packages are available at: https://dev.dns-oarc.net/packages/

In examples/ you'll now also find:

modules/input-example
This input example is based on dnsjit.input.zero which was a testing modules during the early days of dnsjit.
It's a C module that generates empty objects for the receiver.
modules/filter-example:
This filter example is C module that counts the number of objects passed to it before sending it to the receiver.
modules/output-example:
This output example is based on dnsjit.output.null which was a testing modules during the early days of dnsjit.
It's a C module that will just discard objects it receives.
modules/lib-example:
This example Lua module takes two core_timespec_t C objects and gives the duration between them as a string.
stand-alone-tool:
This example is based on test_pcap_read.lua and test_throughput.lua which was previous located in examples/.
There are two installable Lua programs and shows how to depend on a dnsjit version, depend on specific dnsjit modules and how to run tests using make test.

All these examples can easily be copied and renamed to build and distribute your own dnsjit modules and tools, using autotool for configure, make and make install.

Development files will also be installed, or can be installed via dnsjit-dev/dnsjit-devel packages. All C headers have been prefixed with dnsjit/ (for example #include <dnsjit/version.h>).

Thanks to this new setup, the module output.dnssim has been moved out from dnsjit's repository and placed in DNS shotgun's: https://gitlab.nic.cz/knot/shotgun/-/tree/master/replay/dnssim
This will help CZ.NIC to maintain and release both the module and tool at the same time.

New modules:

Added input.zpcap, module for reading LZ4/ZSTD compressed PCAPs
Added core.loader, module for loading C modules using LuaJIT's ffi interface and package.cpath
Added core.file with core_file_exists(), a C function to check if a file exists

Other changes:

Add <dnsjit/version.h> for DNSJIT_MAJOR_VERSION, DNSJIT_MINOR_VERSION, DNSJIT_PATCH_VERSION
dnsjit: Remove version print on start
dnsjit.input.zero: Will require("example.input.zero") for backwards compatibility
dnsjit.output.null: Will require("example.output.null") for backwards compatibility
core/timespec: Add :max_init(), return a new object with maximum values set for seconds and nanoseconds.
output/pcap:
- Update open() man-page, indicate usage of pcap_dump_open()
- Add have_errors() to check for write errors during/after dumping
input.fpcap: Add fadvise_sequential() to advise sequential read of the file
examples/dumpdns.lua: Add support for dumping compressed PCAPs

Bugfixes:

lib/getopt: Fix short options, error if length is not 1
core/timespec: Fix typo in struct documentation

v1.1.0

d21f025

Release 1.1.0

This releases adds a new module for handling Base64 URLs and new calls for error handling and opening PCAPs using file descriptors, along with a bug fix in lib.getopt and other changes.

Packages are available at: https://dev.dns-oarc.net/packages/

The dnssim module has also gotten its own version and changelog, this is to prepare it for being moved outside of dnsjit's repository in the future.

New modules, calls, features:

New lib.base64url: Utility library to convert data to base64url format
core.log: New call Log.errstr(): Convert error number to its text representation
input.fpcap: New call Fpcap.openfp(): Open a PCAP file for processing using a file descriptor, for example io.stdin
output.dnssim: Support for DNS-over-HTTPS

Bug fixes:

lib.getopt: Fix bug where - and -- could not be used as arguments to options

Other changes:

Fix typo in configure help text
Add coverage
filter.ipsplit: Extend PRNG modulus to 2^31, new implementation is the same as glibc's rand()
lib.ip: Fix typo in documentation
output.dnssim:
- This module now has it's own changelog
- Updated to v20210129
- Depend on libhttp2 for dnssim DNS-over-HTTPS capabilities
output.pcap: Log libpcap error when failing to open
SUSE packages now depend on moonjit because of lack of LuaJIT support
