debugcommands: introduce debugrevlogindex (BC) `hg debugindex` was originally invented for displaying revlog index data and is highly tailored towards that. e.g. it accepts a --format option to display index data for a particular revlog version and displays things like offset and length. As we support non-revlog storage, it makes sense for `hg debugindex` to display generic index data and for there to exist storage-specific or storage-aware debug* commands for dumping non-generic index data. This commit effectively renames `hg debugindex` to `hg debugrevlogindex` and replaces `hg debugindex` with a version that is storage agnostic. Tests using --format have been updated to use `hg debugrevlogindex`. Output is backwards compatible. The replacement command uses the formatter, which means output can be templatized. At some point, we may want to tweak output (e.g. to add the revision size). But I don't feel like taking a bigger BC break at the moment. The renamed command/function had to be moved because check-code enforces alphabetical ordering of commands in this file. Differential Revision: https://phab.mercurial-scm.org/D4358

debugcommands: use openstorage() in debugdata (BC) Nothing we're doing here requires a revlog. So use openstorage(). .. bc:: `hg debugdata` no longer accepts the path to a revlog file. Differential Revision: https://phab.mercurial-scm.org/D4357

tests: use inline Python for revlog test `hg debugdata` will soon stop accepting the raw path to a revlog file. Adjust a test accordingly. The changed test is for a security bug. So this should be reviewed with scrutiny. Differential Revision: https://phab.mercurial-scm.org/D4356

debugcommands: use openstorage() in debugindexdot And add test coverage for changelog and manifests. Differential Revision: https://phab.mercurial-scm.org/D4355

cmdutil: return a revlog from openrevlog() and split function The filelog class is a wrapper around a revlog instance. I have plans to give manifests and the changelog a similar treatment. When filelog was ported away from revlog and when I started writing patches to do the same for manifests, I noticed that a lot of debug* and perf* commands were relying on low-level revlog APIs like start(), end(), deltaparent(), etc. For filelog, I added these to the interface, even though I didn't want to because they don't belong on a generic storage interface. For manifest (and eventually changelog), the pain is too much to bear. We need to cut the tight coupling. These debug* and perf* commands use cmdutil.openrevlog() to obtain a revlog instance. This commit effectively renames openrevlog() to openstorage(), adds an argument to ensure a revlog instance is returned, and introduces a replacement openrevlog() that calls openstorage() such that a revlog instance is returned. By doing things this way, we allow the debug* and perf* commands to still work on revlog-based repositories without having to expose low-level revlog APIs in the storage interfaces. The practical side-effect of this on the current code base is we return a revlog instance instead of a filelog. The manifest and changelog are not affected at this time. Some of filelog's storage APIs are different from revlog. For example, read() strips the optional header containing copy/rename metadata. This may impact some perf* commands. But I don't think the impact is worth worrying about. Upcoming commits will port existing consumers to openstorage(), where appropriate. This commit does cause some test regressions when using the simple store. These will be fixed as commands are ported to use storage APIs. .. api:: cmdutil.openrevlog() now returns a revlog instance or aborts Previously, it would return a storage object, which may not be a revlog instance. Use the new cmdutil.openstorage() API to return an object conforming to the storage interface of the thing you are accessing if you don't need a revlog instance.

merge: improve interactive one-changed one-deleted message (issue5550) I like the wording from the bug, so I figured I'd package it up in a change and see what people think. Differential Revision: https://phab.mercurial-scm.org/D4336

bookmark: add an --active flag to display the active bookmark There is currently no official simple way to retrieve the current bookmark. In particular for automation. We add a `--active` flag to the `hg bookmarks` command. When set, the command display the current bookmark name if any or return 1. For now, this flag is read-only. However sensible combinations exist with `--delete`, `--rename` and `--rev` and can be implemented later.

phase: use `_phase` revset instead of string interpolation The previous code was hackyer and assume all phases had an associated revset. The later might no longer be true once we introduce more internal phase.

phase: expose a `_phase(idx)` revset Internally phase related revset are calling the `_phase` function. We expose it as an internal revset. This is useful to refer to phase in revset doing debatable things around the phase name.

phase: handle phase with no command flag Before this changeset, all existing phases have a corresponding flag on the `hg phase` command. (eg: `hg phase --draft`). After this changeset, a phase can exists without having an associated flag. This is useful to introduce a new internal phase that we do not want to expose to user.

phase: explicitly exclude secret phase and above The comment explicitly mention the secret phase so we should as well use that in the code.

phase: use `trackedphases` in `_getphaserevsnative` Instead of manually listing secret and draft, simply use the `trackedphases` constant. The constant is already used by `_getphaserevsnative`.

lfs: add a progress bar when searching for blobs to upload The search itself can take an extreme amount of time if there are a lot of revisions involved.

i18n: merge i18n comments of translatable texts correctly Before this patch, i18n comments of translatable texts are lost at creation of hg.pot file, if: - same translatable text appears multiple times, - the 1st appearance does not have i18n comment, and - any of rest has it For example, previous patch for filemerge.py adds translatable texts with i18n comments, but these comments are lost, because: - automatically added texts in docstring of internal merge tools are picked up earlier than these translatable texts, because of location in filemerge.py - but docstring has no i18n comment This patch makes addentry() of posplit merge i18n comments of later translatable texts, in order to keep them at creation of hg.pot.
