1. About

This was a long weekend of in-depth Mercurial discussion, design, and coding. The sprint took place October 8th-10th 2010 at Google Chicago.

Sprints are open to all significant Mercurial contributors. See 1.5sprint for history.

3. What happened at the sprint?

Here's a mostly complete overview of features, discussions, bugs, patches, etc. that came up (from a posting to mercurial-devel by Brodie):

3.1. Big new features

• Online help in hg serve/hgweb (durin42)

• Parentdelta support (reduces repo size) (not yet enabled by default) (tonfa)

3.2. Unfinished business

• Greatly improved changeset discovery (speeds up push/pull) (tonfa)
• "Liquid HG" - a system for safely allowing mutable history (mpm)

• "Dead heads" support for marking changesets as abandoned (via pushkey) (mg, original email, patch queue)

• Better templater/templating language
• Revset support everywhere -r/--rev is used (mpm)
• "Black box" extension that records warnings, errors, etc. (nicdumz)
• Improved extension error messages (nicdumz)

• Test potential migration from Roundup to http://trac.edgewall.org/ for bug tracking (bmp, brodie)

• No prompts from "hg merge" (use hg resolve to handle merges at your own pace instead) (muggs)

• Automated PyPI upload through setup.py (tonfa, brodie)

• hg config --edit (brodie, kiilerix, mg)
• More consistent/reliable internal URL parsing (brodie, kiilerix)

• Fine-grained HGPLAIN (e.g., make stuff plain except i18n) (brodie)

3.3. Discussions

• Cleaning up and reorganizing the wiki
• Scaling hgweb (smarter etags, better caching)

• Improving Google Summer of Code (mpm, brodie, durin42, tonfa, nicdumz, mg)

• Improving extension debugging (extensions could provide homepage URLs, their own version numbers, and specify what versions of Mercurial they support)

• Better changeset signing support (support for more tools, commitsigs integration, pushkey-based changeset signing)

• Moving extdiff into core and making it use merge-tools settings

• Moving other extensions into core (progress, record, transplant, graphlog)

• Better auto-generated documentation (via Sphinx, epydoc, etc.)

• Adding more command examples in help

• Better documenting how --verbose/--quiet affects different commands

• Better documenting internal:* merge settings

• Specifying merge tools on the command line

• Improving the release process

• Improving subrepo support (should we use it ourselves? polib is a candidate)

3.4. Patches for bugs

• issue2364 - merge: handle no file parent in backwards merge (mpm)

• issue2373 - ui.paths: expand paths directly in fixconfig (tonfa)

• issue2427 - mq: handle deleting the same patch twice in one command (danchr)

• issue2191 - progress: make sure stderr has isatty before calling (durin42)

• issue2074 - windows: handle spaces in path to Python (bmp)

• issue2417 - import: don't strip '#' lines from patch descriptions (kiilerix)

• issue2376 - dispatch: properly handle relative path aliases used with -R (brodie)

• issue2361 - revset: lower precedence of minus infix (mpm)

• issue1564 - strip: add --keep flag to avoid modifying wc during strip (durin42)

3.5. Other interesting patches that made it in

• setup/hg: always load Mercurial from where it was installed. (10da5a1f25dd) (danchr)
• setup: user-friendly error message if Python headers are missing (6c0e1aee1b19) (nicdumz)

• pager: don't run pager if nothing is written to stdout/stderr (05077896ffe2) (brodie)

• pager: add global --pager=<auto/boolean> option (04f6de46bf3a) (brodie)
