Mercurial: Changelog

setup: refactor the version string to a subset of tag+tagdist-hash+date Here is an array summarizing the mercurial version string: [A] [B] [C] [D] [1] clone tag clean => tag [2] clone hash clean => latesttag+latesttagdistance-hash [3] clone tag dirty => tag+date [4] clone hash dirty => latesttag+latesttagdistance-hash+date [5] archive tag clean => tag [6] archive hash clean => latesttag+latesttagdistance-hash Column [A]: Mercurial built from an hg *archive* or hg *clone* working directory Column [B]: revision built has a *tag* or else default to the SHA1 *hash* Column [C]: working tree *clean* or *dirty* Column [D]: Mercurial version string Over the previous version: - row [5] did return just the node hash, now it returns the tag - prepend the latest tag and the distance to it to rows [2][4][6] - append also the date to row [3]; previously, it was just the tag - the version string is with an empty string to avoid possible TypeError exceptions during string manipulations - factorize the function to run hg commands; remove the error message as it is no more specific to the function. This scheme enables to have first part of the version strings that can be compared, whether it has been built from a tagged or untagged revision. The second part of the version adds a hash for untagged revisions and today's date if the working tree has local modifications. As the version string does not contain spaces or special characters, it should not break script parsing the 'hg version' command and should be usable for use in file names. The new code also ensure that the version string has exactly the same version string, whether it has been built from an archive or from a clone.

archive: add branch and tag informations to the .hg_archival.txt file Up to this changeset, only the repo (first node) and current node hash were included. This adds also the named branch and tags. So the additional lines to .hg_archival.txt are branch: the named branch tag: the global tags of this revision, one per line in case of multiple tags latesttag: if the revision is untagged, the latest tag (most recent in ancestors), again one per line if this ancestor has multiple tags. latestagdistance: the longest distance (changesets) to this latest ancestor.

ui: only use "user@host" as username in noninteractive mode We regularly see people on IRC ask how they can correct commits they accidentally made without having configured a username. This change will make Mercurial abort when a commit is made without a username. If Mercurial is run without a TTY (from a cronjob or similar), a username is constructed as usual. Schematically the changes are as follows: With ui.askusername=False: old new interactive user@host abort noninteractive user@host user@host With ui.askusername=True: old new interactive prompt prompt noninteractive user@host user@host
