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.

help: fix typo in log examples

ssl: on OS X, use a dummy cert to trick Python/OpenSSL to use system CA certs This will give PKI-secure behaviour out of the box, without any configuration. Setting web.cacerts to any value or empty will disable this trick. This dummy cert trick only works on OS X 10.6+, but 10.5 had Python 2.5 which didn't have certificate validation at all.

ssl: refactor sslkwargs - move things around a bit, preparing for next change

revert: special case 'hg revert --all' On large repos, hg revert --all can take over 13 seconds. This is mainly due to it walking the tree three times: once to find the list of files in the dirstate, once to find the list of files in the target, and once to compute the status from the dirstate to the target. This optimizes the hg revert --all case to only require the final status. This speeds it up to 1.3 seconds or so (with hgwatchman enabled). Further optimizations could be done for the -r NODE and pattern cases, but they are significantly more complex.

test-commandserver: make runcommand message bolder It seems ' runcommand' is difficult to distinguish from command output. '*** runcommand' is slightly better.

test-commandserver: rewrite manual substitution of output by (glob) match

test-commandserver: remove redundant banner output Since test output was inlined, "testing <func>" message should no longer be necessary.

test-commandserver: remove .py test which was ported to .t

test-commandserver: port test functions from .py to .t Though we have to duplicate import statements, .t test is still more handy than .py test which has cryptic .out file. This change allows to skip a part of test by #if conditional, which my next patch series depends on.

test-commandserver: add stub for .t test by copying .out with 2-space indent Currently test-commandserver.t only contains output, so it is skipped by #require false.

test-commandserver: split helper functions to new hgclient module This prepares for porting test-commandserver.py to .t test. Though command-server test needs many Python codes, .t test will be more readable than .py test thanks to inlined output.

heredoctest: do not append extra newline character to continuation line Trailing newline characters are kept in lines.

heredoctest: use the same dict for local/global contexts as in doctest In order to mimic module-level evaluation, globals and locals should be the same object, so doctest does not pass separate locals dict. https://docs.python.org/2.7/reference/simple_stmts.html#exec This fixes NameError in the following example: >>> import foo >>> def bar(): ... foo # must exist in globalvars

cmdserver: drop useless in_ attribute from channeledoutput The previous patch makes sure that in_ == out, so it's no longer needed to keep in_ for __getattr__. Also, it seems strange for channeledoutput to have in_ stream which is actually a writable file object.

cmdserver: get file attributes of 'e'-channel from stdout, not from stderr It seems wrong to get attributes from object different than the underlying file. In the following example, it doesn't make sense to flush stderr after writing to stdout: self.ferr.write(str(a)) if not getattr(self.ferr, 'closed', False): self.ferr.flush()

cmdserver: correct doc of channeledoutput in_ is only used as the source of file attributes.

commands: add debuglocks to report/clear lock state

test-convert-git.t: make copy detection deterministic Since both 'bar' and 'bar-copied' matched 'bar-copied2', Git's copy detection would sometimes result in 'bar' being the source for 'bar-copied2' and sometimes 'bar-copied'. Change bar in a separate commit so that that would no longer be the case.

revsetbenchmark: add a rebase-related revset to the benchmark list

revsetbenchmark: allow comments ('#' prefix) in the revset input

revsetbenchmark: make it clear that revsets may be read from stdin

tags: use full hash for formatter output as in log or annotate commands

tags: change field name of formatter output to be the same as log command Since -T option is not public yet, this won't break backward compatibility.

files: correct topic of formatter

revert: move targetsubs calculation down to its use A future patch will be reorganizing this section of the code into two paths, and targetsubs complicates this by existing in the middle of one path, but not the other. We fix that by moving it 200 lines down, to the only place it's used.
