Any Apache CouchDB user is free to test a source release, and in fact we encourage you to do so!
This might seem like a complex process, but that is only because it has been documented very thoroughly to make sure that we're all doing the same thing. Once you've done this a few times, the whole process becomes very easy to remember.
Setting Up
Remove any existing temporary directory:
Code Block |
---|
rm -rf /tmp/couchdb |
Obviously, don't run this command if you're already using this directory for something else.
The location isn't important, but this is a sensible default.
Create a new temporary directory to work in:
Code Block |
---|
mkdir /tmp/couchdb |
You can safely remove this directory and all of its contents when you're done.
Downloading the Release Candidate
You should have a copy of the vote email with links to the candidate files.
You should now create a another temporary directory:
Code Block |
---|
mkdir /tmp/couchdb/dist |
Change into it:
Code Block |
---|
cd /tmp/couchdb/dist |
And then download these files:
Code Block |
---|
wget https://dist.apache.org/repos/dist/dev/couchdb/source/VERSION/CANDIDATE/apache-couchdb-VERSION.tar.gz wget https://dist.apache.org/repos/dist/dev/couchdb/source/VERSION/CANDIDATE/apache-couchdb-VERSION.tar.gz.asc wget https://dist.apache.org/repos/dist/dev/couchdb/source/VERSION/CANDIDATE/apache-couchdb-VERSION.tar.gz.sha256 wget https://dist.apache.org/repos/dist/dev/couchdb/source/VERSION/CANDIDATE/apache-couchdb-VERSION.tar.gz.sha512 |
The appropriate commands should be in the email for you to copy and paste.
The VERSION and CANDIDATE bits will change between releases.
If you don't have wget installed, you can use curl -O which should do the same thing.
Verifying the Candidate
All release managers should have their keys in this file:
You will need to import the keys into your local keychain before you can continue:
Code Block |
---|
curl https://apache.org/dist/couchdb/KEYS | gpg --import - |
Info | ||
---|---|---|
| ||
If you don't have GPG installed, you will get this message:
Install GPG to continue. |
Once that is done, you can verify the release signature:
Code Block |
---|
gpg --verify apache-couchdb-*.tar.gz.asc |
Check for:
- "Good signature from" message.
- The release manager's name, email, and key.
If anything at all about this output look strange to you, please flag it up on the mailing list.
You must then check the SHA256 checksum of the release:
Code Block |
---|
sha256sum --check apache-couchdb-*.tar.gz.sha256 |
Check for an "OK" message.

If you're using macOS and you don't have
Afterwards, you may need to also do this:
|
You must then check the SHA512 checksum of the release:
Code Block |
---|
sha512sum --check apache-couchdb-*.tar.gz.sha512 |
Check for an "OK" message.
Checking the Candidate
Skip this section if you don't know anything about the build system.
You should have an ish file which contains the Git tree-ish used to build the release.
Create two new temporary directories:
Code Block |
---|
mkdir /tmp/couchdb/git mkdir /tmp/couchdb/tree |
Make a pristine copy from the tree-ish.
Code Block |
---|
git clone https://git-wip-us.apache.org/repos/asf/couchdb.git /tmp/couchdb/git cd /tmp/couchdb/git git archive --prefix=/tmp/couchdb/tree/ `cat /tmp/couchdb/dist/apache-couchdb-*.tar.gz.ish` | tar -Pxf - |
Change into your dist directory:
Code Block |
---|
cd /tmp/couchdb/dist |
Unpack the tarball:
Code Block |
---|
tar -xvzf apache-couchdb-*.tar.gz |
Compare the contents of the tarball to the release tag:
Code Block |
---|
diff -r apache-couchdb-VERSION ../tree |
Replace VERSION with the version you are testing.
Lines starting with "Only in ../tree" should be part of bootstrap mechanism or source control configuration.
Lines starting with "Only in apache-couchdb-VERSION" should be files produced by the bootstrap mechanism.
Nothing else should ever appear in this output.
If you have no idea what any of this means, you probably should have skipped this section!
Sample healthy output:
Code Block |
---|
Only in ../tree: .gitignore Only in apache-couchdb-1.2.0: INSTALL Only in apache-couchdb-1.2.0: Makefile.in Only in apache-couchdb-1.2.0: acinclude.m4 Only in ../tree: acinclude.m4.in Only in apache-couchdb-1.2.0: aclocal.m4 Only in apache-couchdb-1.2.0/bin: Makefile.in Only in ../tree: bootstrap Only in apache-couchdb-1.2.0: build-aux Only in apache-couchdb-1.2.0: config.h.in Only in apache-couchdb-1.2.0: configure Only in apache-couchdb-1.2.0/etc: Makefile.in [...] Only in apache-couchdb-1.2.0/etc/windows: Makefile.in Only in apache-couchdb-1.2.0/m4: ac_check_curl.m4 Only in ../tree/m4: ac_check_curl.m4.gz Only in apache-couchdb-1.2.0/m4: ac_check_icu.m4 Only in ../tree/m4: ac_check_icu.m4.gz Only in apache-couchdb-1.2.0/m4: libtool.m4 [...] Only in apache-couchdb-1.2.0/m4: lt~obsolete.m4 Only in apache-couchdb-1.2.0/share: Makefile.in [...] Only in apache-couchdb-1.2.0/var: Makefile.in |
These are the standard checks and are also performed by the release scripts.
However, assume that you cannot trust:
- The source code the archive was built from.
- The host operating system the archive was built on.
An attacker may have compromised either.
Accordingly, you should subject the release candidate to a number of your own tests.
Some ideas:
- Verify the contents of the generated files.
- Spot check a few of the "Only in apache-couchdb-VERSION" files.
- Prepare your own reference candidate and compare the files.
- Audit the types of file contained within the archive.
- Run a virus scanner on the archive.
This part of the process is left to your discretion.
Checking the Code
Change into your dist directory:
Code Block |
---|
cd /tmp/couchdb/dist |
Unpack the tarball (if you haven't already done so in the previous steps):
Code Block |
---|
tar -xvzf apache-couchdb-*.tar.gz |
Obviously, skip this step if you've already unpacked the tarball.
Change into the tarball directory:
Code Block |
---|
cd apache-couchdb-VERSION |
Replace VERSION with the version you are testing.
Configure CouchDB to install into your temporary directory:
Code Block |
---|
./configure -c |
Test the whole package:
Code Block |
---|
make check |
If you passed additional arguments to ./configure, you will need to pass them as an environment variable to make.
Do something like this:
Code Block |
---|
DISTCHECK_CONFIGURE_FLAGS="--additional-argument" make check |
This will take a while. You may want to grab a hot beverage.
If this is successful, it should output something like:
Code Block |
---|
====================================================== apache-couchdb-VERSION archives ready for distribution: apache-couchdb-VERSION.tar.gz ====================================================== |
If a test fails, you can run it again:
Code Block |
---|
$ ./test/etap/run test/etap/060-kt-merging.t |
Where 060-kt-merging is the name of the specific test you want to run.
If this step is failing consistently, you should see the Troubleshooting section below.
Install CouchDB into your temporary directory:
Code Block |
---|
make release |
Start CouchDB:
Code Block |
---|
/tmp/couchdb/dist/apache-couchdb-VERSION/rel/couchdb/bin/couchdb |
If you get the following error:
Code Block |
---|
Apache CouchDB 1.2.0 (LogLevel=info) is starting. Failure to start Mochiweb: eaddrinuse |
You already have a CouchDB server listening on the default port.
Edit your local.ini file:
Code Block |
---|
$EDITOR /tmp/couchdb/install/etc/couchdb/local.ini |
Look for this:
Code Block |
---|
[httpd] ;port = 5984 |
And change it to this:
Code Block |
---|
[httpd] port = 5985 |
Restart CouchDB.
CouchDB should now be running and listening for connections.
Visit:
If you had to change the port number in the previous step, you must update it here too.
Locate the "Verify Installation" link in the sidebar.
Verify your installation.
Wrapping it Up
If you manage to get all the way through this without a single error, the release is good. Please reply to the vote email with a summary of the steps you completed. If anything strange happens, or you run into any problems, please reply to the vote email with an outline of the steps you took, and the problems you noticed. In some cases, it might be due to a slight difference in test setup. If that is the case, please update this document to help future testers.
Troubleshooting
The test suite can be a little brittle at times.
This is most noticeable when you are running the distcheck target, as the test suite is run multiple times.
If you want to automatically run the distcheck target multiple times, there is a script for that.
Change into the temporary directory:
Code Block |
---|
cd /tmp/couchdb |
Grab a copy of the admin resources:
Code Block |
---|
git clone http://git-wip-us.apache.org/repos/asf/couchdb-admin.git |
Change into the dist directory:
Code Block |
---|
cd /tmp/couchdb/dist |
Run the script:
Code Block |
---|
../couchdb-admin/auto_distcheck.sh VERSION |
Replace VERSION with the version you are testing.
This script will run the distcheck target in a loop forever, or until the build succeeds — whichever comes first.
Make sure you understand and are comfortable with this before you run it.
