David Steele 6e8a45f650 v2.53: Concurrent Backups
IMPORTANT NOTE: The log-level-stderr option default has been changed from warn to off. This makes it easier to capture errors when only redirecting stdout. To preserve the prior behavior set log-level-stderr=warn.

NOTE TO PACKAGERS: The lz4 library is now required by the meson build.

NOTE TO PACKAGERS: Compiler support for __builtin_clzl() and __builtin_bswap64() is now required by the meson build.

Bug Fixes:

* Fix SFTP renaming failure when file already exists. (Fixed by Reid Thompson. Reviewed by David Steele. Reported by ahmed112212.)

Features:

* Allow backups to run concurrently on different repositories. (Reviewed by Reid Thompson, Stefan Fercot.)
* Support IP-based SANs for TLS certificate validation. (Contributed by David Christensen. Reviewed by David Steele.)

Improvements:

* Default log-level-stderr option to off. (Reviewed by Greg Sabino Mullane, Stefan Fercot.)
* Allow alternative WAL segment sizes for PostgreSQL ≤ 10. (Contributed by Viktor Kurilko. Reviewed by David Steele.)
* Add hint to check SFTP authorization log. (Contributed by Vitalii Zurian. Reviewed by Reid Thompson, David Steele.)

Documentation Improvements:

* Clarify archive-push multi-repo behavior. (Reviewed by Stefan Fercot.)

pgBackRest
Building Documentation

General Builds

The pgBackRest documentation can output a variety of formats and target several platforms and PostgreSQL versions.

This will build all documentation with defaults:

./doc.pl

The user guide can be built for rhel and debian. This will build the HTML user guide for RHEL:

./doc.pl --out=html --include=user-guide --var=os-type=rhel

Documentation generation will build a cache of all executed statements and use the cache to build the documentation quickly if no executed statements have changed. This makes proofing text-only edits very fast, but sometimes it is useful to do a full build without using the cache:

./doc.pl --out=html --include=user-guide --var=os-type=rhel --no-cache

Each os-type has a default container image that will be used as a base for creating hosts but it may be useful to change the image.

./doc.pl --out=html --include=user-guide --var=os-type=debian --var=os-image=debian:9
./doc.pl --out=html --include=user-guide --var=os-type=rhel --var=os-image=centos:7

The following is a sample RHEL 7 configuration that can be used for building the documentation.

# Install docker
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
sudo yum install -y docker-ce
sudo systemctl start docker

# Install tools
sudo yum install -y git wget

# Install latex (for building PDF)
sudo yum install -y texlive texlive-titlesec texlive-sectsty texlive-framed texlive-epstopdf ghostscript

# Install Perl modules via CPAN that do not have packages
sudo yum install -y yum cpanminus
sudo yum groupinstall -y "Development Tools" "Development Libraries"
sudo cpanm install --force XML::Checker::Parser

# Add documentation test user
sudo groupadd test
sudo adduser -gtest -n testdoc
sudo usermod -aG docker testdoc

Building with Packages

A user-specified package can be used when building the documentation. Since the documentation exercises most pgBackRest functionality this is a great way to smoke-test packages.

The package must be located within the pgBackRest repo and the specified path should be relative to the repository base. test/package is a good default path to use.

Ubuntu 16.04:

./doc.pl --out=html --include=user-guide --no-cache --var=os-type=debian --var=os-image=ubuntu:16.04 --var=package=test/package/pgbackrest_2.08-0_amd64.deb

RHEL 7:

./doc.pl --out=html --include=user-guide --no-cache --var=os-type=rhel --var=os-image=centos:7 --var=package=test/package/pgbackrest-2.08-1.el7.x86_64.rpm

RHEL 8:

./doc.pl --out=html --include=user-guide --no-cache --var=os-type=rhel --var=os-image=centos:8 --var=package=test/package/pgbackrest-2.08-1.el8.x86_64.rpm

Packages can be built with test.pl using the following configuration on top of the configuration given for building the documentation.

# Install recent git
sudo yum remove -y git
sudo yum install -y https://centos7.iuscommunity.org/ius-release.rpm
sudo yum install -y git2u-all

# Install Perl modules
sudo yum install -y perl-ExtUtils-ParseXS perl-ExtUtils-Embed perl-ExtUtils-MakeMaker perl-YAML-LibYAML

# Install dev libraries
sudo yum install -y libxml2-devel openssl-devel

# Add test user with sudo privileges
sudo adduser -gtest -n test
sudo usermod -aG docker test
sudo chmod 750 /home/test

sudo echo 'test ALL=(ALL) NOPASSWD: ALL' > /etc/sudoers.d/pgbackrest

# Add pgbackrest user required by tests
sudo adduser -gtest -n pgbackrest
