Obsolescense-based shelve only needs metadata stored in .hg/shelved and if feels that this metadata should be stored in a simplekeyvaluefile format for potential extensibility purposes. I want to avoid storing it in an unstructured text file where order of lines determines their semantical meanings (as now happens in .hg/shelvedstate. .hg/rebasestate and I suspect other state files as well). Not included in this series, I have ~30 commits, doubling test-shelve.t in size and testing almost every tested shelve usecase for obs-shelve. Here's the series for the curious now: http://pastebin.com/tGJKx0vM I would like to send it to the mailing list and get accepted as well, but: 1. it's big, so should I send like 6 patches a time or so? 2. instead of having a commit per test case, it more like a commit per some amount of copy-pasted code. I tried to keep it meaningful and named commits somewhat properly, but it is far from this list standards IMO. Any advice on how to get it in without turning it into a 100 commits and spending many days writing descriptions? 3. it makes test-shelve.t run for twice as long (and it is already a slow test). Newest test-shelve.r runs for ~1 minute.

"""save and restore changes to the working directory
|
|
|
|
The "hg shelve" command saves changes made to the working directory
|
|
and reverts those changes, resetting the working directory to a clean
|
|
state.
|
|
|
|
Later on, the "hg unshelve" command restores the changes saved by "hg
|
|
shelve". Changes can be restored even after updating to a different
|
|
parent, in which case Mercurial's merge machinery will resolve any
|
|
conflicts if necessary.
|
|
|
|
You can have more than one shelved change outstanding at a time; each
|
|
shelved change has a distinct name. For details, see the help for "hg
|
|
shelve".

If a shelved change is applied successfully, the bundle that

between your changes and the commits you are unshelving onto. If

this occurs, you must resolve the conflict, then use

``--continue`` to complete the unshelve operation. (The bundle
|
|
will not be moved until you successfully complete the unshelve.)
|

|

(Alternatively, you can use ``--abort`` to abandon an unshelve
|
|
that causes a conflict. This reverts the unshelved changes, and
|
|
leaves the bundle in place.)

|
|
If bare shelved change(when no files are specified, without interactive,

include and exclude option) was done on newly created branch it would

After a successful unshelve, the shelved changes are stored in a
|

backup directory. Only the N most recent backups are kept. N
|

defaults to 10 but can be overridden using the ``shelve.maxbackups``
|
|
configuration option.
|

.. container:: verbose
|

Timestamp in seconds is used to decide order of backups. More

than ``maxbackups`` backups are kept, if same timestamp

|
|
Shelving takes files that "hg status" reports as not clean, saves
|
|
the modifications to a bundle (a shelved change), and reverts the
|
|
files so that their state in the working directory becomes clean.
|
|
|
|
To restore these changes to the working directory, using "hg
|
|
unshelve"; this will work even if you switch to a different
|
|
commit.
|
|
|
|
When no files are specified, "hg shelve" saves all not-clean
|
|
files. If specific files or directories are named, only changes to
|
|
those files are shelved.
|
|
|
|
In bare shelve (when no files are specified, without interactive,
|
|
include and exclude option), shelving remembers information if the
|
|
working directory was on newly created branch, in other words working
|
|
directory was on different branch than its first parent. In this
|
|
situation unshelving restores branch information to the working directory.
|
|
|
|
Each shelved change has a name that makes it easier to find later.
|
|
The name of a shelved change defaults to being based on the active
|
|
bookmark, or if there is no active bookmark, the current named
|
|
branch. To specify a different name, use ``--name``.
|
|
|
|
To see a list of existing shelved changes, use the ``--list``
|
|
option. For each shelved change, this will print its name, age,
|
|
and description; use ``--patch`` or ``--stat`` for more details.
|
|
|
|
To delete specific shelved changes, use ``--delete``. To delete
|
|
all shelved changes, use ``--cleanup``.
