[libvirt] [PATCHv2 00/12] Switch from yajl to Jansson

Per the discussion here: https://www.redhat.com/archives/libvir-list/2017-November/msg00225.html Switch from using yajl to Jansson. v1: https://www.redhat.com/archives/libvir-list/2018-March/msg01781.html Patches 5-11 are meant to be squashed together before pushing, but are posted separately here in hope it will make reviewing them easier. Ján Tomko (12): virJSONValue: remove unused 'protect' property tests: replace references to yajl build: add --with-jansson build: undef WITH_JANSSON for SETUID_RPC_CLIENT Switch from yajl to Jansson FIXUP: Adjust test data for Jansson FIXUP: Remove functions using yajl FIXUP: make nss depend on Jansson instead of yajl FIXUP: compile and link with Jansson instead of yajl FIXUP: s/WITH_YAJL/WITH_JANSSON/ FIXUP: libvirt.spec: use jansson instead of yajl build: require Jansson if QEMU driver is enabled config-post.h | 1 + configure.ac | 3 + libvirt.spec.in | 4 +- m4/virt-driver-qemu.m4 | 8 +- m4/virt-jansson.m4 | 29 + m4/virt-nss.m4 | 4 +- m4/virt-yajl.m4 | 27 +- src/Makefile.am | 8 +- src/qemu/qemu_driver.c | 2 +- src/util/Makefile.inc.am | 4 +- src/util/virjson.c | 614 ++++++--------------- tests/Makefile.am | 12 +- tests/cputest.c | 16 +- tests/libxlxml2domconfigtest.c | 4 +- tests/qemuagenttest.c | 4 +- .../xml2json/file-backing_basic-aio_threads.json | 9 +- .../file-backing_basic-cache-directsync.json | 9 +- .../xml2json/file-backing_basic-cache-none.json | 9 +- .../xml2json/file-backing_basic-cache-unsafe.json | 9 +- .../file-backing_basic-cache-writeback.json | 9 +- .../file-backing_basic-cache-writethrough.json | 9 +- .../xml2json/file-backing_basic-detect.json | 9 +- .../xml2json/file-backing_basic-noopts.json | 9 +- .../xml2json/file-backing_basic-unmap-detect.json | 9 +- .../xml2json/file-backing_basic-unmap-ignore.json | 9 +- .../xml2json/file-backing_basic-unmap.json | 9 +- .../file-qcow2-backing-chain-encryption.json | 3 +- .../xml2json/file-qcow2-backing-chain-noopts.json | 27 +- .../file-qcow2-backing-chain-unterminated.json | 3 +- .../network-qcow2-backing-chain-cache-unsafe.json | 3 +- ...etwork-qcow2-backing-chain-encryption_auth.json | 3 +- tests/qemucapabilitiestest.c | 4 +- tests/qemucaps2xmltest.c | 4 +- tests/qemucommandutiltest.c | 4 +- tests/qemuhotplugtest.c | 4 +- tests/qemumigparamsdata/empty.json | 4 +- tests/qemumigparamsdata/unsupported.json | 4 +- tests/qemumigparamstest.c | 4 +- tests/qemumonitorjsontest.c | 4 +- tests/virmacmaptestdata/empty.json | 4 +- tests/virmocklibxl.c | 4 +- tests/virnetdaemontest.c | 2 +- tests/virstoragetest.c | 4 +- 43 files changed, 292 insertions(+), 632 deletions(-) create mode 100644 m4/virt-jansson.m4 -- 2.16.1

ACK, cool that we can get rid of it.

Yajl has not seen much activity upstream recently. Switch to using Jansson >= 2.7. All the platforms we target on https://libvirt.org/platforms.html have a version >= 2.7 listed on the sites below: https://repology.org/metapackage/jansson/versions https://build.opensuse.org/package/show/devel:libraries:c_c++/libjansson Implement virJSONValue{From,To}String using Jansson, delete the yajl code (and the related virJSONParser structure) and report an error if someone explicitly specifies --with-yajl. Also adjust the test data to account for Jansson's different whitespace usage for empty arrays and tune up the specfile to keep 'make rpm' working when bisecting.

Hmm, this could be simplified if you create JSON_LIBS/JSON_CFLAGS and refactor it prior to this patch and then just change the value used to fill those.

v1 used that approach because it (temporarily) allowed to choose between yajl and Jansson. I did not want to introduce a 1:1 alias to keep it simpler and take advantage of our m4 macros, which set the WITH_ _CFLAGS and _LIBS automatically. Hopefully this library will last us another 10 years and by then, libvirt will have been rewritten into #Go++ already. Jano

Fair enough. Keep it as in this patch then.

ACK to this bit.

So is the ordering of execution of these guaranteed? In other words, will 'with_najsson' be always resolved at this point? Also I agree with this check, but I'm not entirely persuaded by the rest of the patch. Maybe it can be split into two, since it does two separate things.
