LibreOffice ecosystem interview: Caolán McNamara at Red Hat

LibreOffice is developed by a worldwide community, made up of volunteers, certified developers and companies in the wider ecosystem. Today we’re talking to Caolán McNamara, a long-time LibreOffice developer who works for Red Hat…

Tell us a bit about yourself!

I’m a Principal Engineer at Red Hat, Inc. on the Desktop Team since 2004! And I live on the west coast of Ireland.

What does Red Hat do in the LibreOffice ecosystem?

We try and do a lot of different things, from integration with the GNOME desktop, Calc and UNO work, and porting to architectures such as aarch64 and ppc64le, but I can highlight some of the efforts we make in detecting flaws close to when they get introduced into LibreOffice.

We maintain the regular crashtesting infrastructure, where we import and export 120,000+ documents and typically fix, or identify the triggering commit, any new import/export failures as they are discovered.

Similarly, we maintain the LibreOffice Coverity instance and work to keep the warnings to an effectively zero level in over six million lines of code, as part of that early detection of code flaw process.

In the same theme, we manage the LibreOffice OSS-Fuzz work and work to maintain the level of import related issues to a minimum, especially as a tool to detect potentially security related regressions before they are released, with over 1000 fixed to date.

We recently released LibreOffice 7.3 – what did you work on in that version?

The last user interface feature I did for 7.3 was a little rework of the calc autofilter dropdown, to add “popup on hover” of the color filter submenus and adding color names and some other tweaks, which itself was just an extension of Samuel Mehrbrodt’s (allotropia) more substantial LibreOffice 7.2 work to support color filtering in the autofilter.

Another feature we worked on that landed in upstream 7.3 was extension of the command line conversion of spreadsheets to comma separated value files to additionally support the optional export of each tab of a spreadsheet to a separate output CSV file.

Looking beyond this release, what else are you planning to do?

I’m working on GTK4 version of LibreOffice. It’s not finished by any means, but it’s mostly functional and making progress.

LibreOffice 7.3 Community is better than ever at interoperability

In addition to the majority of code commits being focused on interoperability with Microsoft’s proprietary file formats, there is a wealth of new features targeted at users migrating from Office, to simplify the transition

Berlin, February 2, 2022 – LibreOffice 7.3 Community, the new major release of the volunteer-supported free office suite for desktop productivity, is available from https://www.libreoffice.org/download. Based on the LibreOffice Technology platform for personal productivity on desktop, mobile and cloud, it provides a large number of improvements targeted at users migrating from Microsoft Office to LibreOffice, or exchanging documents between the two office suites.

There are three different kinds of interoperability improvements:

  • Development of new features, such as the new handling of change tracking in tables and when text is moved, which have a positive impact on interoperability with Microsoft Office documents.
  • Performance improvements when opening large DOCX and XLSX/XLSM files, improved rendering speed of some complex documents, and new rendering speed improvements when using the Skia back-end introduced with LibreOffice 7.1.
  • Improvements to import/export filters: DOC (greatly improved list/numbering import); DOCX (greatly improved list/numbering import; hyperlinks attached to shapes are now imported/exported; fix permission for editing; track change of paragraph style); XLSX (decreased row height for Office XLSX files; cell indent doesn’t increase on each save; fix permission for editing; better support of XLSX charts); and PPTX (fixed interactions and hyperlinks on images; fix the incorrect import/export of PPTX slide footers; fix hyperlinks on images and shapes; transparent shadow for tables).

In addition, LibreOffice’s Help has also been improved to support all users, with a particular attention for those switching from Microsoft Office: search results – which are now using FlexSearch instead of Fuzzysort for indexing – are focused on the user’s current module, while Help pages for Calc Functions have been reviewed for accuracy and completeness and linked to Calc Function wiki pages, while Help pages for the ScriptForge scripting library have been updated.

ScriptForge libraries, which make it easier to develop macros, have also been extended with various features: the addition of a new Chart service, to define charts stored in Calc sheets; a new PopupMenu service, to describe the menu to be displayed after a mouse event; an extensive option for Printer Management, with a list of fonts and printers; and a feature to export documents to PDF with full management of PDF options. The whole set of services is available with identical syntax and behavior for Python and Basic.

LibreOffice offers the highest level of compatibility in the office suite market segment, starting with native support for the OpenDocument Format (ODF) – beating proprietary formats in the areas of security and robustness – to superior support for DOCX, XLSX and PPTX files. In addition, LibreOffice provides filters for a large number of legacy document formats, to return ownership and control to users.

Microsoft files are still based on the proprietary format deprecated by ISO in 2008, and not on the ISO approved standard, so they hide a large amount of artificial complexity. This causes handling issues with LibreOffice, which defaults to a true open standard format (the OpenDocument Format).

LibreOffice 7.3 is available natively for Apple Silicon, a series of processors designed by Apple and based on the ARM architecture. The option has been added to the default ones available on the download page.

A video summarizing the top new features in LibreOffice 7.3 Community is available on YouTube: https://www.youtube.com/watch?v=Raw0LIxyoRU and PeerTube: https://peertube.opencloud.lu/w/iTavJYSS9YYvnW43anFLeC.

A description of all new features is available in the Release Notes [1]

Contributors to LibreOffice 7.3 Community

LibreOffice 7.3 Community’s new features have been developed by 147 contributors: 69% of code commits are from the 49 developers employed by three companies sitting in TDF’s Advisory Board – Collabora, Red Hat and allotropia – or other organizations (including The Document Foundation), and 31% are from 98 individual volunteers.

In addition, 641 volunteers have provided localizations in 155 languages. LibreOffice 7.3 Community is released in 120 different language versions, more than any other free or proprietary software, and as such can be used in the native language (L1) by over 5.4 billion people worldwide. In addition, over 2.3 billion people speak one of those 120 languages as their second language (L2).

LibreOffice for Enterprises

For enterprise-class deployments, TDF strongly recommends the LibreOffice Enterprise family of applications from ecosystem partners – for desktop, mobile and cloud – with a large number of dedicated value-added features. These include long-term support options, professional assistance, personalized developments and other benefits such as SLA (Service Level Agreements): https://www.libreoffice.org/download/libreoffice-in-business/.

Despite this recommendation, an increasing number of enterprises are using the version supported by volunteers, instead of the version optimized for their needs and supported by the different ecosystem companies.

Over time, this represents a problem for the sustainability of the LibreOffice project, because it slows down the evolution of the project. In fact, every line of code developed by ecosystem companies for their enterprise customers is shared with the community on the master code repository, and improves the LibreOffice Technology platform.

Products based on LibreOffice Technology are available for major desktop operating systems (Windows, macOS, Linux and Chrome OS), for mobile platforms (Android and iOS), and for the cloud. Slowing down the development of the platform is hurting users at every level, and the LibreOffice project may fall short of its expectations and possibilities.

Migrations to LibreOffice

The Document Foundation has developed a Migration Protocol to support enterprises moving from proprietary office suites to LibreOffice, which is based on the deployment of an LTS version from the LibreOffice Enterprise family, plus migration consultancy and training sourced from certified professionals who offer value-added solutions in line with proprietary offerings. Reference: https://www.libreoffice.org/get-help/professional-support/.

In fact, LibreOffice – thanks to its mature codebase, rich feature set, strong support for open standards, excellent compatibility and LTS options from certified partners – is the ideal solution for businesses that want to regain control of their data and free themselves from vendor lock-in.

Availability of LibreOffice 7.3 Community

LibreOffice 7.3 Community is immediately available from the following link: https://www.libreoffice.org/download/. Minimum requirements for proprietary operating systems are Microsoft Windows 7 SP1 and Apple macOS 10.12.

LibreOffice Technology-based products for Android and iOS are listed here: https://www.libreoffice.org/download/android-and-ios/, while for App Stores and ChromeOS are listed here: https://www.libreoffice.org/download/libreoffice-from-microsoft-and-mac-app-stores/

For users whose main objective is personal productivity, and therefore prefer a release that has undergone more testing and bug fixing over the new features, The Document Foundation maintains the LibreOffice 7.2 family, which includes some months of back-ported fixes. The current version is LibreOffice 7.2.5.

The Document Foundation does not provide technical support for users, although they can get it from volunteers on user mailing lists and the Ask LibreOffice website: https://ask.libreoffice.org
LibreOffice users, free software advocates and community members can support The Document Foundation with a donation at https://www.libreoffice.org/donate.

LibreOffice 7.3 is built with document conversion libraries from the Document Liberation Project: https://www.documentliberation.org

LibreOffice project and community recap: January 2022

Here’s our summary of updates, events and activities in the LibreOffice project in the last four weeks – click the links to learn more…

  • We started the month by announcing our plans for FOSDEM, which will take place online on February 5 – 6. The LibreOffice community will be present with many talks – join us!

  • Our awesome documentation community created a macOS version of the LibreOffice Writer Guide 7.2. This includes changes specific to the macOS version of the suite.

  • Meanwhile, we noticed that many OpenOffice users are receiving warning dialogs when opening files made in LibreOffice. This is because LibreOffice supports newer versions of OpenDocument Format, its native format, which aren’t available in OpenOffice. Click here to learn more.

Keep in touch – follow us on Twitter, Facebook and Mastodon. Like what we do? Support our community with a donation – or join us and help to make LibreOffice even better!

Bug bounties: finding and fixing security holes with European Commission funds

Free and open source software (FOSS) is about much more than driving costs down, in some cases even down to zero – it’s about giving control back to users, developers and even nations. With FOSS, everyone gains the freedom to study, improve and share the software – and to use it whenever and wherever they want, without being restricted by vendor lock-in strategies.

FOSS has been widely used amongst government bodies and public services, so thanks to the coordination of their recently formed Open Source Programme Office (OSPO), the European Commission has started a series of hackathon and “bug bounty” programmes to help selected projects find (and potentially fix) security issues.

The Commission’s OSPO has set aside €200,000 to reward developers and researchers who find critical security vulnerabilities in free software projects (such as LibreOffice and Mastodon).

Rewards go from €250 up to €5000 for security bug disclosures, with 20% added on top if the researchers provide also a fix for the bug.

This will surely help to further improve the security and reliability of FOSS tools, benefiting everyone from individual users to larger governmental and public bodies, and to make FOSS known to those that haven’t yet discovered how much it has to offer.

Paolo Vecchi, from The Document Foundation’s Board of Directors, which liaised with the European Commission’s OSPO, adds:

It is a real pleasure to see that the European Commission is following up their open source software strategy 2020-2023 with concrete actions. The creation of the OSPO, which is led by very knowledgeable and passionate people, was the first step required to then progress into other programmes, like this bug bounty, which will provide the needed support for an open source ecosystem that has become the foundation of all the platforms and software we use.

The Document Foundation and our community are grateful for the opportunity that has been provided with to make LibreOffice even more secure and ready to potentially become the preferred open source office suite also within European institutions.

We encourage all developers to head to the bug bounty page and help us to make open source even more secure for all.
