* SyncTarget now persists the remote timeline after pushing to it.
* Added SyncTarget.shutdown() to allow callers to signal the sync timer thread
to stop.
* Fixed a bug where a SyncTarget was added instanciated times.
* Added `edit` which uses the program in $EDITOR to allow the user to edit the
current timeline marker.
* Added `delete` to remove the current timeline marker from the timeline.
* Added support for using a named TTY device in order to use an interactive
program ($EDITOR in this case) to take over interaction with the user. There
is still a problem with this, in that a process by default only has access to
its controlling TTY device. This mean, for example, that redirecting the
subprocess input and output to the TTY will fail to work properly if the
timestamper CLI process is not part of the same process group as the process
owning the TTY the user is interacting with. This is the case when using
nailgun: the java process running TimeStamperCLI is not part of the same
process group as the user's client shell.
I think TTY device permissions may be alterable, and we can work around this
by changing the permissions for the current TTY in the launcher script that
invokes the nailgun client. Needs more investigation.
* Added package build target to create a zip of the CLI standalone installation.
* Added route back for PUT /ts_api/user/<username>
* Fixed typo in ``ts_api:put_user/2``.
* Fixed incorrect expected return from ``ts_ext_data:set_property/3``.
* Added missing assignment for ``ts_user.email`` in the appropriate
``ts_json:construct_record/3`` clause.
* Fixed model attribute assignment in ``ts.js``.
* Transformed the test database to match the new data model. Added
``ts_ext_data`` table and moved ``ts_user.ext_data`` values to it.
* Added D0022: cascade delete ``ts_ext_data`` when ``ts_entry`` record is
deleted.
* Completed refactor of ``ts_api`` functions to account for extended data:
* ``post_entry/3``
* ``put_entry/3``
* Created ``ts_entry:write/2`` to write extended data atomically with the entry.
* Fixed copy/paste bug in ``ts_ext_data:create_table/1``.
* Fixed implementation of ``ts_ext_data:set_property/3`` to be explicit about
taking a record, not a reference. It then extracts the reference and passes it
to the underlying implementation in ``ts_ext_data:do_set_property/3``.
* Refactored ``ts_ext_data:do_set_property/3`` to take a record *reference*, not
the record itself.
* Refactored the ``ts_ext_data:get_property/2`` and
``ts_ext_data:get_properties/1`` functions to return key value tuple pairs,
not ``ts_ext_data{}`` records.
* Refactored ``ts_json:ext_data_to_ejson{1,2}`` from a function that iterates
over a list of extended data properties and returns a transformed list to
``ts_json:ext_data_to_ejson/1``, a function that transforms one extended data
property. The iteration behavior is acheived using ``lists:map/2``.
* Refactored ``ts_json:ejson_to_ext_data{1,2}`` in a similar fashion to
``ts_json:ext_data_to_ejson{1,2}``.
* Fixed ``ts_json:construct_record/3`` to use ``ts_json:ejson_to_ext_data/1``.
------------------
* Created the extended data table. This is a more generic version of the
extended data field that was on ``ts_user``. Instead of arbitrary key-value
pairs going in a list on the user record we will have an additional table, a
one to many relationship between existing tables and the ``ts_ext_data``
table, each row being an extended value of the corresponding record.
* Added support to the ``timestamper:create_tables/1`` and
``timestamper_dev:create_table/1`` functions for the new ``ts_ext_data`` table.
Documentation
-------------
* Added some general docs about the DB layer code.
* Added two new issues, *D0020*: Entry exclusion filters and *D0021*: notes width.
API Changes
-----------
Necessitated by the change to the data model.
* Updated ``ts_api`` data-retrieval functions to use extended data:
* ``get_user_summary/2``
* ``list_timelines/2``
* ``list_entries/3``
* Updated ``ts_api:put_timeline/3`` to parse the extended data supplied by the
caller. *FIXME* it is not actually saving this data.
* TODO: Started updating ``ts_api:post_entry/3`` to handle extended data, need
to finish.
Database Layer
--------------
Changes necessitated by the change to the model.
* Added ``ts_common:do_set_ext_data/2`` which iterates through the extended data
key-value pairs calling ``ts_ext_data:set_property/3``. It does not provide a
transaction context.
* Split ``ts_common:new/1`` and ``ts_common:update/1`` functions into multiple
functions to prevent code-duplication:
* ``do_{new,update}`` contains the code that performs integrity checks and
the actual database write function. It does this assuming that it is being
called from within the context of an mnesia transaction (uses
``mnesia:read`` and ``mnesia:write``).
* ``{new,update}/1`` performs the same function as previously. The
implementation changed from using mnesia ``dirty_*`` calls to prociding a
transaction and calling ``do_{new,update}/1``.
* ``{new,update}/2`` expect the record to update/create and the extended
data to write atomically with the record. They provide a transaction
context, call ``do_{new,update}/1``, then call ``do_set_ext_data/2``.
* Similar to the refactoring of ``ts_common:{new,update}/1``,
``ts_entry:{new,update}/1`` have been refactored into multiple methods each to
support extended data properties:
* ``do_{new,update}/1`` perform the actual update assuming we have already
established an mnesia transaction.
* ``{new,update}/1`` behave the same as they used to, but now do so by
creating an mnesia transaction and calling ``do_{new,update}/1``.
* ``{new,update}/2`` create an mnesia transaction, call
``do_{new,update}/1``, and then call ``ts_common:do_set_ext_data/2``.
* Again similar to the refactoring of ``ts_common:{new,update}/1``,
``ts_user:{new,update}/1`` have been refactored into multiple methods each to
support extended data properties:
* ``do_{new,update}/1`` perform the actual update assuming we have already
established an mnesia transaction.
* ``{new,update}/1`` behave the same as they used to, but now do so by
creating an mnesia transaction and calling ``do_{new,update}/1``.
* ``{new,update}/2`` create an mnesia transaction, call
``do_{new,update}/1``, and then call ``ts_common:do_set_ext_data/2``.
* Created the ``ts_ext_data`` module as the interface to the extended data
properties introduced in the data model:
* ``create_table/1`` performs the same function as it does in the other db
layer modules, creates the table with the appropriate structure given the
more general table options desired (location, storage type, etc.).
* ``set_property/3`` takes a record, a property key, and a property value as
input and sets the property described by the property key on the record to
the given value, assuming this is a valid property for the record to have.
For example, currently the ``ts_user`` record can have an associated
property, ``last_timeline``, which represents the last timeline the user
was working with. Trying to pass this property with a ``ts_entry`` record
would result in an exception. This function uses
``ts_ext_data:do_set_property/3`` as its underlying implementation.
* ``get_property/2`` takes a record and a property key and returns the value
of that property for the given record, or ``not_set`` if the property has
not been set on that record. This method creates its own mnesia
transaction.
* ``get_properties/1`` takes a record and returns a list of key-value tuples
representing all of the extended data properties set for the given record.
This method creates its own mnesia transaction.
* ``do_set_property/3`` takes a record reference (not the whole record), a
a property key, and adds the property assignment to the ``ts_ext_data``
table. It creates its own mnesia transaction.
* Added ``new/2`` and ``update/2`` to the ``ts_timeline`` module to support
extended data properties. They delegate implementation to
``ts_common:{new,update}/2``.
JSON Encoding/Decoding
----------------------
Changes necessitated by the change to the data model.
The JSON objects now contain a potentially unlimited number of fields, as each
extended data property is encoded as a seperate field, and looks no different
from any of the required fields on the object. The intended explanation in API
documentation is that each object type (``user``, ``timeline``, or ``entry``)
now has both *required* fields that *MUST* be present in every message in either
direction and *optional* fields that may or may not be present in any
communication with the API. There should be a clear distinction between which
fields are required and which are optional. It might also be a good idea to
provide a suggested default for optional values when they are not present.
* Updated documentation about JSON record structures to reflect the fact that
there are now potentially many optional attributes in addition to the required
attributes for each record.
* ``record_to_ejson/1`` refactored to ``record_to_ejson/2`` which also takes
the extended data attributes and appends them as additional attributes to
the end of the record structure.
* Created ``ext_data_to_ejson/{1,2}`` to provide a mechanism for reformatting
extended data properties whose internal representations are not immediately
translatable into JSON. Currently only the ``entry_exclusions`` property,
which is a list of strings, needs to be treated this way (changing from
``[val, val]`` to ``{array, [val, val]}`` as needed by ``json:encode/1``.
``ext_data_to_ejson/1`` acts as a more user-friendly facade to
``ext_data_to_ejson/2``.
* Rewrote ``ejson_to_record/{2,3}`` and ``ejson_to_record_strict/{2,3}`` to
handle extended data. They now use a common method, ``construct_record/3`` to
create the actual record object and extended data key-value list.
``ejson_to_record_strict/{2,3}`` only differs in that it checks for the
presence of each required field of the record after the record is constructed.
The three-parameter versions of these functions also take in the intended
reference for the constructed record, replacing anything that is in the EJSON
body as the record reference (useful when the body does not have the record
ids). These methods now return a tuple: ``{Record, ExtData}`` instead of just
the record.
* Created ``construct_record/3`` takes a record and the EJSON fields from the
input object. The third parameter is an accumulator for the extended data
properties found when constructing the record. This method works by iterating
over the list of input fields. It recognizes any required fields and updates
the record being built with the value. Any fields it does not recognize it
assumes are extended data properties and adds to its list. When all input
fields have been visited it returns the record and list it has constructed.
* ``ejson_to_ext_data/{1,2}`` is the inverse of ``ext_data_to_ejson/{1,2}``.
*TODO*: this method is not actually being used by the ``ejson_to_record*``
methods.
* Added personal VIM ide extension.
* Implemented timeline selection (resolves D0007)
* Slightly restyled the new timeline button and timeline list menu.
* Resolved issues:
* #0006: Fix timeline menu UI.
* #0015: Create new timeline button in timeline menu.
* #0017: Implement timeline creation.
* Removed ts_api:post_timeline/3, corresponded to `POST` to
`/ts_api/timelines/<user-id>`, which makes no sense as there is no way to
auto-generate new timeline-ids.
* Changed ts_api:put_timeline/3 to use ts_timeline:write. This resolved#0017.
* Changed ts_api:put_entry/4 to use ts_entry:write.
* Implemented ts_entry:write/1 and ts_timeline:write/1. These functions are
simple passthroughs to mnesia:dirty_write/1.
* Added clarifing documentation for ts_json:record_to_ejson JSON formats.
* Renamed ts_json:ejson_to_record/2 to ts_json:ejson_to_record_strict/2 and
added ts_json:ejson_to_record/2 as a lax version of the same.
* Updated all ts_api functions to use updated ts_json methods.
* Fixed returned information in ts_api:put_timeline/3
* Added UI for new timeline button.
* Added client-side implementation of new timeline creation. There is a problem
on the server-side, PUT should support creating new items and updating
existing items.
- Switched from a global reset in www/css/ts-screen.scss to a selected
top-level elements reset to allow default formatting for user notes.
- Restructured the #entry-list and entry displays.
- Restructured notes div, now has a sub-div for text and a textarea
element for input.
- Added Showdown.js, a JavaScript Markdown library for formatting comments.
- Moved EntryView blur events to the View events map.
- Added images for expansion of notes.
- Added the ability to edit notes.
- Split EntryListView.addOne into renderOne and addOne so that renderOne
can be called with a new entry (fixes duration glitch)
Client Behaviour (ts.js)
========================
- Created EntryView.getViewModel: translates model data to view data,
specifically synthesizes the start time and duration from the timestamp.
- Added nextModel option to EntryView, needed for calculating the entry
duration.
- Created EntryView.formatStart: given the timestamp, return the start time,
in HH:MM format. Code is written for both 24hr and 12hr format, still need
to write a selector mechanism. For now, uses 12hr format.
- Created EntryView.formatDuration: Get the duration of the entry based on
this entry's timestamp and and the next entry's timestamp in a display-able
form. If nextModel is `null` or `undefined` it is assumed that `model`
is the most recent model and duration is calculated against the current time.
- Changed EntryView.render to use getViewModel.
- Added 'blur' listeners to the mark and timestamp input fields to close them
without persisting the changes.
- Created EntryView.update: Refresh the display based on the model using the
existing DOM elements.
- EntryView.save() now uses EntryView.update() instead of EntryView.render()
and no longer includes an implicit close()
- EntryView.close() has been split into seperate save() and close() functions,
to persist the changes and hide the input dialogs, respectively.
- EntryListView.addOne now passes the nextModel to EntryViews is creates.
- EntryListView.createNewEntryOnEnter() now clear the new intry input after
creating a new entry.
- EntryListView.render() now uses a for-structure to traverse the entry
collection and passes the nextModel (if there is one) to EntryListView.addOne.
Client UI (ts-screen.scss)
==========================
- Font size, family, and color adjusted on timeline and user input fields.
- Day seperator secondary header colors adjusted.
- Mark column width shortened, timestamp and duration columns widened.
- Styles added for notes UI
Client UI (index.yaws)
======================
- Markup changes needed for getViewModel chanes.
- Expanded day seperator.

Using atoms will not scale in the large. Also, using atoms as keys forced the
API to convert arbitrary end-user input to atoms, adding another potential
drain of the finite atom-space available.
- ts_api: url paths are now treated and matched as lists, not atoms.
Usernames and API calls all use lists now.
- ts_json: key items (username, timeline ids) are now expected to be lists,
not atoms.
- POST and PUT were being used counter to typical usage, POST updating existing
records and PUT creating new ones. Changed to PUT updating existing records
and POST creating records.
- Instead of returning Meta-Data (status) in the header and the body, we now
only return the content in the body, except in error when we return the error
message.
- JSON entries use the 'id' name for entity ids (instead of 'username',
'timeline_id', and 'entry_id')
Added 'default' make target to only compile.
Reset development configuration.
Commented out starts of tests.
Added sign-up GUI to login panel.
Moved application from /ts/ to /
- Changed ts_api:dispatch_user/3 to return information for the user currently,
authenticated if a valid session id is presented and no username is presented.
- Moved the generic styling of form > * elements to be specific to .bar > form.
- Added jQuery U 1.8.0.
- Created login dialog that will automatically load upon page load if the user
is not logged in.
- Added styling for jQuery UI login dialog.
- Implemented login functionality on the client page.
- Implemented functionality to load user and timeline records on the client
side.
Created timestamper module to start the application.
Added cookie-based authentication to ts_api.
Added utility methods to ts_api:
* make_json_400/1 and make_json_400/1
* make_json_401/1 and make_json_401/2
* parse_json_body/1 reads a JSON object from a HTTP request body.
Implemented ts_api_session module to manage api user sessions.
Fixed ts_entry:list* methods to be 0-indexed.
Removed the ts_json:ejson_to_record/1 implementation for ts_user records.
Decided that ts_user records are never trusted from the client,
manipulation of fields such as pwd, username will be restricted to
app pages.
Changed the password hashing algorithm. Now uses SHA1(pwd + 256bit salt).
Want to use bcrypt, investingating cross-platform bcrypt implementation.
Fixed yaws.conf config file.
Added Makefile, id_counter.erl, and yaws.conf.
Created ts_common module. Will contain common DB code. So far only list/3.
Created ts_timeline module. DB code for storing timeline entries.
Created ts_entry module, DB code for storing timelin entries.
