revert: small refactoring in the way backup value are handled The current backup value may have two different values: 1. Do not try to do backup 2. Do backup if applicable We are about to move to: 1. Do not try to do backup 2. Do backup if applicable 3. Do backup in all cases So we change the current values to make room for the new one.

Added signature for changeset f768c888aaa6

Added tag 3.1.2 for changeset f768c888aaa6

parsers: fix Py2.4 argument parsing issue Since fa53d66b45a8, we were getting this strange message with Py2.4: TypeError: argument 1 must be impossible<bad format char>, not int ..because we were using the 'n' type specifier introduced in 2.5. It turns out that offset is actually a revision number index, which ought to be an int anyway. So we store it in an int, use the 'i' specifier, rely on Py_ParseTuple for range checking, and rename it to avoid type confusion.

diff: document the nobinary option Since 3fbef7ac26f0, we have a diff.nobinary option. This is handy, but the only way I found out about it was by looking at the release notes for 3.1, which is not something I normally do.

filelog: censored files compare against empty data, have 0 size To support "status" operations against working directories that are the children of censored revisions, filelog must define "cmp" and "size" for censored content.

filelog: raise CensoredNodeError when hash checks fail with censor metadata With this change, when a revlog revision hash does not match its content, and the content is empty with a special metadata key, the integrity failure is assumed to be intentionally caused to remove sensitive content from repository history. To allow different Mercurial functionality to handle this scenario differently a more specific exception is raised than "ordinary" hash failures. Alternatives to this approach include, but are not limited to: - Calling a hook when hashes mismatch to allow arbitrary tombstone validation. Cons: Irresponsibly easy to disable integrity checking altogether. - Returning empty revision data eagerly instead of raising, masking the error. Cons: Push/pull won't roundtrip the tombstone, so client repos are unusable. - Doing nothing differently at this layer. Callers must do their own detection of tombstoned data if they want to handle some hash checks and not others. - Impacts dozens of callsites, many of which don't have the revision data - Would probably be missing one or two callsites at any given time - Currently we throw a RevlogError, as do 12 other places in revlog.py. Callers would need to parse the exception message and/or ensure RevlogError is not thrown from any other part of their call tree.

error: add CensoredNodeError, will be thrown when content deliberately erased This change introduces the error plus a corresponding catch in dispatch, to provide localized error messages. The verb "censor" is used in this commit and all following to refer to erasing the content of a revlog revision (filelog, for now) without recalculating node IDs, leaving that revision invalid. Further work must be done to safely share such revision data with compliant clients. I find the analogy to censorship straightforward; for less politically charged options, consider "erase", "excise", "expunge", or "blackhole".

files: cache repo.dirstate For a large repo, 'hg files' goes from 2.27 seconds to 1.92.

files: only check for removed, not unknown or missing ctx.matches() doesn't return unknown files, and repo.dirstate[f] never returns '!' for an answer.

files: use ctx.matches instead of ctx.walk ctx.matches() is an optimized form of ctx.walk() when we don't care about the state of files on disk. For a large repo, 'hg files > /dev/null' drops from 3.7 seconds to 2.3.

files: actually filter out removed files 'hg files' makes an attempt to filter out removed files, but that doesn't work because repo.dirstate[f] returns lowercase 'r', not uppercase.

subrepo: remove superfluous newline from subrepo prompt

ui: show prompt choice if input is not a tty but is forced to be interactive The tests often set ui.interactive to control normally interactive prompts from stdin. That gave an output where it was non-obvious what prompts got which which response, and the output lacked the newline users would see after input. Instead, if the input not is a tty, write the selection and a newline.

help: basic support for showing only specified topic sections For instance, 'hg help config.files' will show only the Files section.

help: use OS containers for config file lists

help: support OS-specific help sections Containers of the form: .. container:: verbose.<os> are shown by default on the given OS (or with -v).

minirst: allow multiple container types for prune If we have a container of type x.y, then we can preserve it by keeping x or y.

config: don't read the same config file twice In some cases some config files would be read twice and shown twice in showconfig --debug.

templater: fix precedence of --style and --template options Since e3eb480a9391, --template option is ignored if --style is specified, which is wrong according to the doc of show_changeset(): Display format will be the first non-empty hit of: 1. option 'template' 2. option 'style' ...

shelve: avoid writing file that is never read from The contents of the .files file has not been used since 1d7a36ff2615 (shelve: use rebase instead of merge (issue4068), 2013-10-23), so stop writing it. Where we currently use the presence of the file as a check for a valid shelve name, switch to checking for the .patch file.

hgk: don't break on repositories with obsolete changesets Check the existence of a changeset before adding it to the list returned by debug-rev-list command.

test: protect the run-tests.py --json test behind an hghave rule We add a rules to detect availability of a json module and skip if json is not available.

hgweb: refresh hgweb.repo on phase change (issue4061) Make hgweb.refresh() also look at phaseroots file (in addition to 00changelog.i file) and reload the repo when os.stat returns different mtime or size than cached, signifying the file was modified. This way if user changes phase of a changeset (secret <-> draft), there's no need to restart hg serve to see the change.
