tests: include detailed trace logs with --write-junit-xml upon failure The JUnit XML format lends itself to be presented in a powerful UI, where you can drill down to the information you are interested in very quickly. For test failures, this usually means that you want to see the detailed trace of the failing tests. With Travis CI, we passed the `--verbose-log` option to get those traces. However, that seems excessive, as we do not need/use the logs in almost all of those cases: only when a test fails do we have a way to include the trace. So let's do something different when using Azure DevOps: let's run all the tests with `--quiet` first, and only if a failure is encountered, try to trace the commands as they are executed. Of course, we cannot turn on `--verbose-log` after the fact. So let's just re-run the test with all the same options, adding `--verbose-log`. And then munging the output file into the JUnit XML on the fly. Note: there is an off chance that re-running the test in verbose mode "fixes" the failures (and this does happen from time to time!). That is a possibility we should be able to live with. Ideally, we would label this as "Passed upon rerun", and Azure Pipelines even know about that outcome, but it is not available when using the JUnit XML format for now: https://github.com/Microsoft/azure-pipelines-agent/blob/master/src/Agent.Worker/TestResults/JunitResultReader.cs Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.
Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.
Please read the file INSTALL for installation instructions.
Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.
See Documentation/gittutorial.txt to get started, then see Documentation/giteveryday.txt for a useful minimum set of commands, and Documentation/git-.txt for documentation of each command. If git has been correctly installed, then the tutorial can also be read with man gittutorial or git help tutorial, and the documentation of each command with man git-<commandname> or git help <commandname>.
CVS users may also want to read Documentation/gitcvs-migration.txt (man gitcvs-migration or git help cvs-migration if git is installed).
The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission). To subscribe to the list, send an email with just “subscribe git” in the body to majordomo@vger.kernel.org. The mailing list archives are available at https://public-inbox.org/git/, http://marc.info/?l=git and other archival sites.
Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.
The maintainer frequently sends the “What's cooking” reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.
The name “git” was given by Linus Torvalds when he wrote the very first version. He described the tool as “the stupid content tracker” and the name as (depending on your mood):
