Backporting

Timeline

• Immediate: patchset needed as soon as possible
• Next Minor Stable Release: patchset that needs to be verified in nightly before backport
• Eventually: patchset that needs to be verified in alpha before backport
• No Backport (preferred): patchset for the next major stable

(Optional) Justification

• Emergency security update: patchset fixes CVEs, 0-days, etc
• Censorship event: patchset enables censorship circumvention
• Critical bug-fix: patchset fixes a bug in core-functionality
• Consistency: patchset which would make development easier if it were in both the alpha and release branches; developer tools, build system changes, etc
• Sponsor required: patchset required for sponsor
• Other: please explain

Issue Tracking

• Link resolved issues with appropriate Release Prep issue for changelog generation

Change Description

I've created a script to create a dependency graph in the dot format.

I decided to group some dependencies together, so I added to each project (except for a few ones) a component information. Maybe we can discuss a few projects (e.g., node and cbindgen: they're toolchain, but used only by Firefox. Maybe nasm should be with them).

The script is set to ignore the dependency on some projects, notably:

• container-image
• binutils
• compiler
• go (at least until we have Namecoin dependencies instead of using go.mod/go.sum)

Also, the script ignores firefox-l10n because it isn't trivial to parse (but it's the only project, so not worth to implement a better parser only for it).

How Tested

Created this graph:
