Three passages claimed the code was not on master, which stopped being true at
the merge. The distinction worth keeping is which branch a reference points at:
item 20's file and line references still mean `item-20-message-rows` at 029a50e,
kept unmerged as the record of the presentation the user rejected, while master
carries the card list built on top of it.
|

Replaces the five-column grid with a single column of three-line cards. Item 53
recorded that the columns, not the cues drawn inside them, were what made the
list read as a table of records; item 20 had already shipped finished, tested
and green and been rejected on sight for exactly that reason.
A card is sender and date, subject with the flag, attachment and reply-count
marks, and tags, at one uniform height. Replies indent under a continuous spine
and show only the tags their thread does not carry. The account colour runs down
the card's left edge, replacing the chip that used to eat a third of every
subject line, with matching swatches in the account dropdown. Sorting newest or
oldest first is new and remembered.
Closes items 20, 51, 53 and 60.
The four defects that mattered were all found by rendering cards to an image and
looking at them, with the suite green through every one: a date clipped on unread
cards because bold is wider than the font the layout measured, an accent bar
painted in a colour identical to the background, an expander pill in a palette
role a theme had made equal to Base, and three separate faults from trusting
notmuch's reply depth to mean structure when it only means how notmuch happened
to thread the mail.
|
|
A reply in a thread with no usable In-Reply-To carries depth 0, because that is
how notmuch reports every message of such a thread. CardLayout read depth 0 as
"not nested", so those replies drew flush against their own thread with no
spine, while a nested thread's replies indented normally: the list showed two
different shapes for the same relationship, side by side.
A MESSAGE row is nested at least one level whatever depth it reports. Being a
child row IS the nesting; the depth only says how much further to go.
This is the third fault from the same root. The depth numbering was trusted to
mean structure when it only ever meant "how notmuch happened to thread this":
first it hid a flat thread's replies entirely, then it left the first message
unreachable, and now it drew the survivors without their indent.
|
|
Four faults from the first hand test, two of them behavioural.
An expander that opened onto nothing. setThreadMessages kept only nodes with
depth > 0, and notmuch_thread_get_toplevel_messages returns every message at
depth 0 when a thread carries no usable In-Reply-To, so a flat thread
contributed no children while its card still advertised the count. Measured in
the user's database: of 396 inbox threads three are flat, one of them nine
messages long, and every two-message thread of that kind was affected, which is
exactly why the fault looked like "the expander only works with more than one
reply". The rule is now position, not depth: every message except the first,
which is the root card itself. That is also the correct rule rather than a
workaround, since the row under the root is the second message however notmuch
chose to nest it.
The thread's first message was unreachable. Selecting a root card loaded the
whole thread, so the pane showed every message with only the last expanded, and
no row in the list offered the first one: the reply rows are messages two
onward. The root card now renders its own message, which is what the card
already claims to be. It keeps its thread id, unlike the message-row path, so
mark-read and the tag-change repaint still work; that is asserted, because
clearing it is the obvious way to write this and silently disables both. Before
the replies are loaded the model has no first message to name and the whole
thread stays the honest answer.
Dates ignored the locale. One hardcoded "yyyy-MM-dd hh:mm" produced a US-looking
format on an Italian desktop; QLocale::system() now formats it, and the width
reserved for the date comes from the same function so a longer locale cannot
clip.
The expander was a bare number on the card's own background. It is a pill now,
carrying "3 replies" (and "1 reply", singular), sized from the label actually
drawn and measured in both glyph states so it does not resize under the pointer
on click. Its fill is blended from Text toward Base rather than taken from
QPalette::Button, which is #2b2b2b against a Base of #2b2b2b on the user's
theme: byte identical, so the pill was invisible. A theme may make any two roles
equal; a blend is defined against the surface it sits on and cannot collide with
it. Checked by rendering both a dark and a light palette and looking.
|
|
Both found by rendering real cards to an image and looking at them, not by any
assertion. The suite was green through both.
The date lost the leading digit of its year on every UNREAD card. The layout
reserves the date's width from the font it is handed, which is the view's
regular font, while the delegate paints with the bold one the model supplies for
unread: 154px reserved against 170px needed. CardLayout now measures the date
bold whatever font it is given, so the reserved width cannot be narrower than
what is drawn. A few pixels are wasted on a read card, which is the cheap side of
the trade.
The accent bar was painted correctly and was invisible. Blending the account
colour 0.35 toward the palette's Base, as the plan specified, is a fraction OF
THE ACCOUNT COLOUR, so on a dark theme it produced (0.18, 0.22, 0.26) against a
Base of (0.169, 0.169, 0.169): the background. The blend is dropped entirely.
An account colour is already chosen to be a chip's fill carrying legible text,
so it is muted to begin with, and nothing is drawn on the bar that needs that
contrast. The spine keeps a blend, at 0.55, because it runs the full height of
every reply in an expansion and is a different problem from a 3px edge marker.
The bar is still faint at 3px on a dark theme, since the account colours are
chosen as chip fills. Whether kAccentWidth needs raising cannot be settled
without the user's own accounts, screen and theme; that is Task 10's open
question and it is left open.

The architecture section described ThreadListView as existing to paint a strip
across columns. That was true until this change and is now the opposite of true:
it survives only for the expander hit-test. Kept as one paragraph of history,
since it explains the file's shape, but no longer stated as current behaviour.
Two traps are recorded inverted rather than deleted, because the rule survived
its own reason changing. The reply indent is still asserted on where the TEXT
lands, but where visualRect lies has flipped: it used to report an indent the
text did not have, and now reports none while the text is indented. And Q_ENUM
is documented as insufficient for a queued Q_ARG, which cost a silently dropped
sort argument.
Item 60's recorded cause was wrong and is corrected in place. It was read off
master, where the row arithmetic really is current.row() + 1; the branch had
already fixed it a commit earlier with threadRowOf(). The entry stays, with the
correction, because the reasoning was sound and the tests it demanded now exist.
Items 20, 51 and 53 are marked built on the branch rather than done. Nothing is
merged and the user has not seen it, which is the whole point of Task 10.
|

Two entries, straight to notmuch. This adds a feature rather than replacing one:
the column header was decorative and nothing implemented click-to-sort, so
removing the header with the grid lost nothing.
Stored in uistate.conf, never in the hand-edited config, and range-guarded on
read: a stale file can hold anything, which is the lesson item 58 recorded.
SortOrder needed qRegisterMetaType despite carrying Q_ENUM. Q_ENUM gives the
enum a meta-object entry, not a metatype registered under the name invokeMethod
resolves, so the queued runQuery would have dropped its sort argument at runtime
and every query would have silently run newest-first. Nothing in the suite
exercises a real worker thread, so this was asserted directly rather than left
to a warning nobody would see. It is registered beside the type rather than in
MainWindow's constructor: a first attempt put it there and passed only because
the test that catches it never constructs a MainWindow.
The account dropdown's entries now carry their account's colour as a swatch,
which is what makes the accent bar on a card mean anything: a colour down a
card's edge says nothing until something maps it to a name. Raw colour here
rather than the blended line colour, since a swatch is a filled patch like a
chip rather than a thin line. Its test builds its own two-account config: reading
the environment's made it SKIP wherever no accounts are configured, which is a
test that asserts nothing while reporting success.
|
|
next_thread and prev_thread now walk with indexBelow/indexAbove, skipping
message rows, so they keep meaning thread-to-thread whatever is expanded.
Stepping message-to-message needs no code: QTreeView's own Up/Down walk VISIBLE
rows and already enter an expanded thread, and being the view's key handling
rather than a shortcut they stay inert when the message pane, a menu or an entry
bar has focus.
Item 60 turns out to have been fixed already, in 5487d58 on this branch, by
threadRowOf() walking up to the containing thread before doing the arithmetic.
The backlog entry was written against master, where that helper does not exist,
so it described a defect this branch had resolved a commit earlier. Verified by
writing both failing tests first and watching them pass: from the last reply of
an expanded thread, and from a thread root with its replies showing. They are
kept, because the property they assert is the one this change must not lose.
What the rewrite buys is that nothing is keyed on a row number any more, which
is the rule a deeper tree would break next.
Alt+Up/Down added alongside Ctrl+J/K. That required KeyMap::sequencesFor and a
move from setShortcut to setShortcuts, because the singular setter keeps only
the last binding and the second one was silently unreachable. Alt because
Shift+arrows is the built-in extend-selection that multi-row tagging depends on,
and because a bare arrow cannot be a window shortcut without breaking every text
field in the window, as Return already demonstrated. sequencesFor puts
sequenceFor's own choice first so the menus advertise an unchanged binding, and
sorts the tail, since QHash order is unspecified.
|
|
ThreadListView::paintEvent and its band arithmetic are deleted. The view existed
to paint a strip across five columns; with one column and one delegate painting
the whole card there is nothing to span, and the two faults that arithmetic kept
producing go with it: a deleted row cut in half, and every other row showing a
bare stripe.
What survives is the expander hit-test, because a delegate gets no click of its
own without an editor. It now asks CardDelegate for the rect rather than
recomputing it, so the drawn target and the clickable one cannot drift. The
siblingAtColumn(0) dance is gone: with one column, the index already is column 0.
Item 51 closes here rather than separately. A card is exactly viewport width, so
the view has no horizontal scroll range for a click to scroll into, and the test
asserts that directly.
Two rendering tests had to change how they measure, not merely which index they
name. The indent test asserted on visualRect, which now reports the SAME rect
for a thread and its reply by design, since setIndentation(0) leaves the indent
to CardLayout: it reads contentLeft off the layout instead. And the expander
test reported zero ink over a card the delegate paints 2183 pixels into, because
viewport()->render() returned a blank image, exactly as CLAUDE.md warns; it now
paints the delegate into an image directly and carries a guard proving the probe
can see ink before it reports finding none. Both were mutation-checked.
Two tests are deleted rather than ported. Both existed to prove the row-wide
strip spanned columns a delegate could not reach, which is a property of code
that no longer exists.
|
|
Replaces SubjectDelegate. The tag chips come home from the view: the strip was
painted there only because a delegate cannot paint outside its column and the
strip spanned all five, and with one column there is nothing to span.
RowStyleDelegate is inherited rather than dropped. Its job survives the
redesign: Qt resolves ForegroundRole into the palette's Text roles and prefers
those over HighlightedText, so the read/unread dimming would win on a selected
row and land as grey on the highlight. What it loses is the rest of its body,
which aligned cells against a text band and centred two marker columns; both
described a grid that no longer exists.
A reply's Re: prefix is stripped here. Every reply repeating the thread's
subject is the visual signature of a table of records, which is the thing item
53 is about.
The account chip becomes a bar down the card's left edge, and the reply spines
inherit its colour, so an expanded thread is bounded by one accent from its root
to its last reply without a second line in the gutter. Neither uses the raw
account colour: that colour is chosen to be a chip's fill with legible text on
top, and the same value as a thin line has to be followable down an expansion
without competing with the senders, so it is blended toward the palette's Base
by the weight threadLineColour() already uses. A reply resolves its THREAD's
colour by walking to the root, since AccountColourRole is empty on a message
row and a neutral spine under an accented root would break the continuous edge.
The build is red at this commit; the view and window still name the old
delegate.
|
|
Five columns answered through Qt::DisplayRole; one column cannot, and a card
needs every field at once, so each gets its own role. Qt::DisplayRole keeps
answering the subject, which is what keyboard search and accessibility read.
Three things change shape rather than moving. DateRole hands over the QDateTime
itself, since the card decides how much of a date it has room for and a
pre-formatted string takes that decision away from the delegate. The subject
loses its "(3)" message-count suffix, which the reply count on line 2 now
states. And the two per-column tooltips become one card-wide tooltip, because
the marks no longer have columns of their own to hover.
The build is red at this commit: the view and the delegates still name the
deleted Column enumerators and are rewritten in the commits that follow.
|
|
Split from the delegate deliberately. A delegate needs a live painter and an
exposed view, which is what makes delegate tests fragile: viewport()->render()
returns a blank image in several ordinary situations, and a probe reporting no
ink is likelier broken than the code it tests. Every geometric claim about a
card is made here, where a test is a function call.
Three lines at a uniform height, so setUniformRowHeights(true) survives. Indent
caps at depth 4 with qMin rather than a branch, so depth 5 and depth 50 land in
the same place. The date is measured before the sender, so a long sender elides
instead of painting over it.
Two traps handled that a first pass gets wrong. QRect::right() is inclusive, so
the right edge is carried as an exclusive one and everything sized from it lands
where the padding constant says rather than a pixel short. And QFont::pointSizeF
returns -1 for a font set in pixels, which qt6ct does, so smallFont branches on
which unit the font actually carries instead of silently returning the card's
own size.
|
|
Sorting was hardcoded NEWEST_FIRST. Two orders only: notmuch's other two are
MESSAGE_ID and UNSORTED, neither of which is an order a human wants, and sorting
by sender or subject would have to happen in the model after results arrive,
which fights the batching that makes a large query paint immediately.
loadThread keeps OLDEST_FIRST unconditionally: a thread reads chronologically
whichever way the list is sorted.
|
|
A reply card shows only these. The alternative, a reply's full tag set, was
rejected on measurement rather than taste: in the user's database 7 of 48691
messages carry unread and 75 carry flagged, both already drawn another way, and
every other tag is applied per thread and identical on all its messages. Full
sets would repeat the thread's chips down the whole expansion, which is the
striping the row-wide strip was built to avoid.
|
|
theImportantActionStillWritesTheFlaggedTag arrived from master, where the
thread list is a QTableView, onto a branch where item 20 made it a
QTreeView. findChild<QTableView*> returned null and the test failed on its
first QVERIFY, before reaching anything it was written to check.
Uses the branch's selectThreadRow helper, which is what every other test
here already calls: QTreeView has no selectRow of its own.
|
|
CLAUDE.md described a QTableView over a table model, which has not been true
since the view port. Updated with the traps the port produced, each of which
shipped a plausible-looking broken build before being caught:
- A tree numbers rows per parent, so nothing may be keyed on a row NUMBER.
- drawBranches runs before the row's cells, so an expander on a content
column is painted over by the delegate's background.
- setRootIsDecorated(false) removes the style's HIT AREA along with its
indicator, leaving a glyph that renders and does nothing.
- isExpanded and setExpanded are keyed on column 0.
- A reply's indent must beat the account chip's width, and visualRect
reports the indent correctly even when nothing is visibly indented.
- paintEvent runs after the cells, so a full-row fill erases their text.
Also the notmuch ownership rule, which is a double-free if undone: messages
reached through a thread are freed with it, so walkReplies holds them raw
against this file's own RAII convention.
Item 20 is marked built, not done, and item 53 records why. The user's verdict
on the finished result was that the table view does not fit the use, said with
every cue in and working. That is a design finding rather than a defect: the
item shipped exactly what its four decisions specified, and all four were the
user's own choices. Recording it as a defect would misattribute the cause;
recording nothing would leave the next session building on a rejected design.
Item 53 carries the cause verified in code rather than guessed. A message row
fills the same five columns as a thread row (threadlistmodel.cpp:275-283
mirroring :428-431), so replies land on the same rigid column boundaries as the
threads around them, and the eye reads columns before indentation or tint. The
reference the user gave has no column rules through its reply rows at all, and
that absence is the one thing three added cues cannot supply.
|
|
tagSelected resolved rows to threads with threadAt(index.row()), which is wrong
for a message row: a child's row number indexes its siblings, so acting on a
reply tagged whichever thread sat at that position in the list. It now routes
through ThreadListModel::scopeFor, and a message row's change is sent as message
ids down applyTags with its own MessageTagCommand for undo.
MessageTagCommand stores message ids where ThreadTagCommand stores thread ids,
and that difference is the point rather than an inconsistency: re-resolving the
thread on undo would restore tags across every sibling the action never touched.
sendMessageTagChange deliberately skips the optimistic model update.
applyTagChange is keyed by thread and would repaint the whole row as though
every message in it had changed, which for a one-message edit is a lie the user
watches correct itself on the next query. It keeps the two things that are NOT
optional: the edited-account set, resolved through the containing thread since
the account is a property of the thread, and holding the edit when a sync holds
notmuch's write lock, since the worker's read-write open blocks rather than
failing.
The scope is now stated before an action and after it, naming both the message
count and whether a whole thread went. This is what stands in for the
confirmation dialog CLAUDE.md rules out: undo is the safety net, and undo is
only usable if the user can tell that something larger than they meant has just
happened. Selecting a single message reports no count at all, since reading one
message is not a bulk action.
A mutation that routed message rows down the thread path SURVIVED the whole
suite: undo depth and status text are identical either way while every sibling
gets tagged. anActionOnAMessageRowTagsThatMessageNotTheThread exists because
that gap was found, and asserts on the ids actually sent.
anActionOnAThreadRowSaysItHitTheWholeThread reads the status bar BEFORE draining
the event loop. This binary has no worker, backlog item 36, so the queued write
reaches a database that has never heard of the thread and answers with
errorOccurred, which overwrites the status bar: draining first asserts on that
error and fails against correct code.
|
|
loadMessage queries by id: and returns one MessageRef, always matched, since the
user asked for that message by clicking its row and a stub would answer the
wrong question. An unknown id emits an empty vector rather than an error: a
stale row after a reindex is an ordinary race, not a failure worth the status
bar. The signal fires even when empty so the UI handler runs instead of waiting
for a reply that never comes.
The branch in onThreadSelected is placed BEFORE threadAt(), which is the whole
trap. threadAt takes a top-level row number and a child's row number indexes its
siblings, so handing a message row's number to it loads whichever thread happens
to sit at that position. Mutation-checked: with the branch disabled the test
reports thread 't1' for a reply belonging to 't2', a wrong answer plausible
enough to survive review.
m_currentMessageId and m_currentThreadId are mutually exclusive and each clears
the other, so a queued reply can tell which kind of selection it belongs to.
onMessageLoaded carries a third guard onThreadLoaded does not need: a reply
landing after the selection moved to a thread row would render one message where
the conversation belongs.
No mark-read timer for a message row in this pass. Marking one message of a
thread read is a per-message tag write and the pending-edit map is keyed by
thread; item 28 is the record of what happens when that count goes wrong.
|
|
Indentation alone still read as a table, which was the user's original
complaint about the whole item. Three cues now say the rows belong to the
thread above them: a spine down the left of the expanded block with a stub out
to each reply, a background tint, and text a size down and undimmed only when
unread.
Both colours are mixed from the palette rather than fixed, the same rule
readColour follows: a tint that reads as grouping on a light theme is invisible
or muddy on a dark one. The tint is deliberately near the threshold of noticing,
since it sits beside the deleted and spam fills, which carry real meaning and
must stay the loudest thing in the list.
The spine is accumulated across the visible reply rows and drawn once after the
loop. Drawn per row it left a gap at every row boundary and read as a column of
dashes rather than as the structure holding the block together.
Two bugs fixed here, both mine, both from the previous commit:
Clicking the expander did nothing. setRootIsDecorated(false), needed to stop
the style painting its own indicator under ours, also removed the style's hit
area, so the glyph rendered perfectly and was inert. ThreadListView handles the
press itself now, over the strip the delegate reserves, leaving the rest of the
subject cell to select the row.
Every click then expanded rather than toggling, because isExpanded and
setExpanded are keyed on column 0 and were being asked about the subject-column
index, which always answers false.
Visible, clickable and toggling are three separate properties and a test for
one passes against the other two being broken: the pixel test proved the
triangle was drawn while it could not be clicked, and the first click test
proved it opened while it could never close. The test now clicks twice and
asserts open then closed.
replyRowsKeepTheirTextUnderTheThreadLine covers the other trap. paintEvent runs
AFTER the cells, so the first version of the tint filled the whole reply row and
erased the sender and subject the delegate had just drawn: zero surviving text
pixels, a block of blank tinted rows. The fill and the stub stay in the band
below the text, where the tag strip lives on thread rows.
|
|
Both were reported from the running application after the previous commit
claimed them working, and the tests that passed could not see either fault.
The expander took four attempts, each of which looked right in code:
- QTreeView::drawBranches is the documented hook and does not work here. It
runs BEFORE the row's cells, so with the expander on a content column the
delegate's own background paints over it. A 60-pixel triangle survived as
8, indistinguishable from the theme's near-invisible dot.
- Sizing the glyph from the row rather than the branch rect put most of it
outside that rect.
- Moving it into SubjectDelegate but calling it from only the no-chip branch
left every real row without one, since every real row has an account chip
and takes the other branch.
It is now drawn by the delegate, which owns the cell and paints after the
background, from both branches, with setRootIsDecorated(false) so the style
does not draw its dot underneath.
The indent was 20px and invisible for a reason the geometry could not show: a
thread row draws an account chip before its subject and a reply row does not, so
a reply's text already starts about a chip's width LEFT of its thread's. The
indent has to beat that before any nesting reads at all, hence 72px.
The indent test asserted on visualRect, which was correctly indented the whole
time, and so passed against a build with no visible nesting. It now measures
where the TEXT lands, accounting for the chip, and fails at 20px. The new
expander test counts painted pixels of the glyph colour against a control row
with no replies, and fails when the call is dropped from either branch.
|
|
Replies are fetched on expansion rather than with the query: walking the reply
tree of every thread in a 10k-thread result would cost more than the query and
almost none of it would be looked at.
hasChildren is what makes that lazy loading work, and its absence would have
shipped the feature unreachable. rowCount is 0 until the worker has walked the
thread, so a view left to infer the expander from rowCount alone draws none, the
user can never expand, and the replies are never requested. It answers from the
summary's totalCount before loading and from the children afterwards, so a
thread whose count included duplicates stops offering an expander that opens
onto nothing.
onThreadTreeLoaded reads the thread id from the reply rather than remembering it
from the request. Two expansions can be in flight at once, and pairing them by
order would attach one thread's replies to the other.
|
|
The strip survived the port because every geometry call it needs exists on both
classes. What did not survive is anything keyed on a row NUMBER: a tree numbers
rows per parent, so row 0 exists once per expanded thread and the old flat 0..N
walk would paint the first thread's strip over every one of them. The walk now
goes by index, and the alternating colour follows visual position rather than
index.row() for the same reason.
QTableView::isRowSelected(int) has no QTreeView equivalent; isSelected on the
index replaces it. MainWindow loses verticalHeader and selectRow, so row height
comes from uniformRowHeights and three helpers replace the row arithmetic.
next_thread and prev_thread now resolve the containing thread first: in a tree
current.row() + 1 is the next SIBLING, which under an expanded thread is the
next reply, not the next thread.
Two test defects found by mutation and worth recording, since both produced a
green suite over a broken assertion:
The indent test asserted on column 0. A QTreeView indents only the column
holding the expander, verified against Qt 6.11: with setTreePosition(4), column
0 reports the same left edge for a thread and its reply while column 4 reports
420 against 440. It was failing against a correctly indented tree.
The strip test passed with the view's skip deleted, because the real model
already returns no pills for a child row, so the view's guard was never the
thing under test. It now runs against a stub model that hands pills to every
row, which leaves the view's skip as the only thing that can keep replies clean.
That rewrite then failed for a third reason: without the delegates MainWindow
installs, rows take the default height, the band is measured against
SubjectDelegate::rowHeightFor and overflows into the row below, and the thread's
own strip paints across the reply. Reads exactly like a missing skip and is not
one.
|
|
ActionScope is what an action is about to touch, resolved from the selection in
one place so no call site reinvents the mapping. A thread root contributes the
whole thread, a message row contributes one message, and messageCount is what
the status bar reports.
The count comes from totalCount, not from the loaded children. A thread that was
never expanded still has all of its messages, and counting only the rows that
happen to be on screen would understate what the action does: mutation-checked,
and the wrong version reports 1 message where 7 are about to be tagged.
A mixed selection is honoured as given rather than escalated to thread scope or
narrowed to message scope. Silently widening it would defeat the reason the
scope is shown at all.
|
|
setThreadMessages drops the depth-0 message: it is the thread's first message
and the root row already stands for it. Keeping it would show a thread of seven
as one root and seven children, contradicting the reply count the row
advertises. Calling again replaces rather than appends, so a thread reloaded
after a sync does not list its replies twice.
A message row reports its own sender and subject, not the thread's. That is the
mistake worth guarding: the thread's author summary usually contains the first
sender too, so reading it renders something plausible for the root's own reply
and wrong for every other one. Mutation-checked, and the wrong version returns
'Alice' where 'Bob' belongs.
Child rows carry no tag pills. The strip is a row-wide band of the thread's
tags; one under each reply would stripe the list and repeat identical tags down
the expansion.
|
|
A table cannot indent or expand, so message rows need a tree. This task changes
only the base class and the index plumbing: no children are produced yet, so the
30 pre-existing tests in test_threadlistmodel are the regression net proving a
thread row still behaves exactly as it did, and QAbstractItemModelTester checks
the index/parent round trip a hand-written assertion would miss.
Two things the table version could leave wrong and a tree cannot. columnCount
returned 0 for a valid parent, which would give message rows no columns and
render them blank. And rowCount now answers only for column 0, since a tree
takes one set of children per row and offering them under every column draws an
expander in each.
The model stays two levels deep even though replies carry a reply depth of their
own. The visual nesting past the first level comes from that depth, not from
further parent-child structure, so no index calculation has to recurse.
|
|
loadThread could not be extended to do this. It walks
notmuch_query_search_messages, and a message obtained that way returns NULL from
notmuch_message_get_replies (notmuch.h:1617-1628), so that walk cannot produce
reply depth at all. The tree comes from notmuch_thread_get_toplevel_messages
instead, and the pane keeps the flat list it wants.
walkReplies takes raw notmuch_message_t*, against this file's rule that every
handle is RAII-owned. Messages reached through a thread are freed with it
(notmuch.h:1637), so an NmMessage wrapper would destroy memory the thread frees
again. The NmThread in the caller is what keeps them alive.
Every message in the thread gets a node regardless of the query: the list is
where the reply count is read, and hiding unmatched replies would make that
count disagree with the rows under it.
Both tests mutation-checked. Flattening depth fails the depth assertion, and
skipping the thread walk fails it too, so neither passes against the two
mistakes the notmuch API invites.

A message row has to be drawn without opening the message, so it needs sender,
subject and date. MessageRef carries none of them: it exists for rendering a
thread into the pane and holds only id, path, tags and matched.
depth defaults to 0, the thread's first message, which the root row stands for
rather than a child row. threadId is carried so a batch of nodes names the
thread it belongs to without the caller tracking it alongside.
|
|
The item sat as 'open, unspecified' since 2026-08-04, recording only that the
user's mental model differed from what was built. Described now from three
screenshots plus four decisions: the left pane gains message rows, the root row
IS the thread's first message, replies indent by true reply depth, and action
scope follows the selected row kind.
No confirmation dialog, per this project's standing rule. The hazard the design
introduces is ambiguity rather than destruction, since deleted is a tag and
every mutation is invertible, so the scope is named in the status bar before and
after the action instead.
Sized L, the largest item in the backlog and the first to warrant a branch.
The plan records four API facts verified against the installed headers, each
contradicting the obvious approach: replies are unreachable from a query walk,
thread-derived messages must not be RAII-wrapped, QTreeView lacks
isRowSelected(int), and a tree numbers rows per parent.
|
|
The user asked to be able to abandon this cleanly. Task 0 now branches
`card-list` off a rebased copy rather than rebasing `item-20-message-rows` in
place, which would have destroyed the record of what the rejected presentation
looked like.
Nothing in the plan touches master, stated as a requirement rather than left to
convention, with the escape hatch written out: `git checkout master` is the
whole of the undo. Task 0 gains a step that verifies master and the original
branch are both where they started, since a rebase onto the wrong branch is
silent and every later task assumes master is the thing to fall back to.
Task 10 now ends by explicitly forbidding a merge. This design was reached by
rejecting a previous one that was finished, tested and green, so a passing suite
is not what decides it: the user looks at the cards. That is the one instruction
most likely to be lost between sessions, and it is the one that matters.
|
|
The plan left the account chip unspecified, because where it sits on a card was
never decided and inventing a place would have been a guess. The user's answer
replaces it rather than placing it: a coloured bar down the card's left edge,
the reply spines inheriting that colour, and matching swatches in the account
dropdown.
It is a net simplification. The chip ate a third of line 2 on every card to
repeat a name the user already knows, which is the table-of-records texture item
53 is about; the bar says the same thing in a few pixels and leaves line 2 to
the subject.
Three details that are easy to get wrong and are specified rather than left to
the implementer:
- The raw account colour is never drawn as a line. It is chosen to be a
chip's FILL, with text drawn on top in whatever stays legible against it. A
thin line on the pane's own background has a different job: followable down
a long expansion without competing with the senders beside it. The accent
blends toward QPalette::Base by the same 0.35 weight threadLineColour()
already uses, keeping the hue and dropping the shout. The dropdown swatch
does use the raw colour, being a filled patch rather than a line.
- A reply resolves its THREAD's colour by walking to the root.
AccountColourRole is empty on a message row, so a spine reading its own
index would fall back to the neutral line under an accented root and break
the continuous edge the design is built on.
- Reply cards carry no bar of their own. Two vertical lines a few pixels
apart in one gutter is what option B looked like, and the spine already
carries the accent.
colourFor() never failing is kept deliberately: an account with no colour= key
gets a stable colour derived from its tag name, so adding an account and
forgetting to colour it degrades to something usable rather than to nothing.
kAccentWidth ships at 3px as a starting value. Whether five accounts are
tellable apart at that width, on this user's screen and theme, is not decidable
from a mockup or a test, so Task 10 gains a step that settles it against real
cards, in both themes, with the guidance to widen the bar before touching the
user's own colour choices.
|
|
Eleven tasks against the card-list spec, TDD throughout, each with its own
mutation check.
Three decisions the plan makes that the spec did not:
- Task 0 rebases the branch first. item-20-message-rows is 15 commits behind
master and conflicts in eight files, one of which carries the item 55
splitter fix in the same file this plan rewrites heavily. Resolving that
while also building a feature would mean debugging a merge and a feature at
once, so it is its own task with its own verification step.
- CardLayout is a separate file from CardDelegate, holding all the geometry
and touching no painter or widget. That is a direct response to the
rendering-probe lessons in CLAUDE.md: a delegate test can be defeated by a
blank render, a pure function cannot.
- Tasks 2, 5 and 6 knowingly leave the build red between commits, since
removing a column across three files cannot be atomic without one enormous
commit. The plan says so at each one and warns against merging mid-plan.
Also recorded: the account chip is specified but has no task, because its
placement on a card was never specified and inventing one would be a guess.
|
|
Both items the spec left open are settled, and one of them turned out to be a
defect rather than the addition it was filed as.
Item 20 deferred "move between messages without returning to the list" as an
addition on top. It is a repair: next_thread and prev_thread are
selectRow(current.row() + 1), and a tree numbers rows per parent, so from the
last reply of an expanded thread row+1 names a sibling that does not exist and
the action silently does nothing. rowCount() with no argument counts top-level
threads, compounding it. Recorded as item 60, since it exists on the branch
whether or not the card list is built, and it is a fresh instance of the exact
rule that branch's own commit message states.
The user asked for arrow keys to skip within a thread and Shift+arrows to skip
between threads, scoped so the keys still work normally in the message pane,
menus and entry bars. Two findings changed the shape of that:
- Up/Down need no binding and no code. QTreeView's built-in navigation walks
VISIBLE rows, so it already steps into an expanded thread's replies, and
being the view's own key handling rather than a shortcut it is inert
whenever focus is elsewhere. The requested focus behaviour is automatic.
- Arrow keys must never become keymap actions. Every action is a QAction with
WindowShortcut, dispatched before the focused widget sees the key, and Qt
withholds only plain LETTERS from editable widgets. Return already proved
this by breaking the query bar and needing a per-widget ShortcutOverride
filter scoped to one widget and one key. Up as a window shortcut would break
the query bar, the tag dialog and the web view at once.
Shift+Up/Down was rejected for thread-jumping: it is the built-in
extend-selection that multi-row tagging and item 20's action scope depend on.
Alt+Up/Down instead, verified free across the whole keymap.
The way back to a whole thread after clicking a reply is the root card, which is
always visible above its replies. Escape is deliberately not overloaded, since
it already means clear-selection with clear-pane on Shift+Escape, and a third
meaning is the half-an-action problem item 50 exists to fix.
The remaining open item is only whether the message pane should change to match,
which stays out of scope: this spec is the left pane.
|
|
Item 53 recorded that message rows read as a table and left the approach
unspecified, with four directions ranging from spanning columns on reply rows to
abandoning message rows entirely. The user's answer is wider than all four: the
column grid is wrong for the WHOLE left pane, threads included.
Threads and replies both become cards in a single column, three lines each, at
one uniform height. Sender and date, then the subject with the flag, attachment
and reply-count marks inline, then the tag chips. Replies indent by depth with a
continuous spine, capped at depth 4.
Three decisions worth their reasoning, since each closed an option that looked
cheaper:
- Uniform height keeps setUniformRowHeights(true), which is the single
cheapest property of the design. A blank third line under untagged cards
buys constant sizeHint arithmetic everywhere else.
- Uncapped indent with a horizontally scrollable pane was asked for and
rejected: it reopens item 51 in a worse form. Cards are viewport width, so
the pane has no horizontal scroll range at all, and item 51 is resolved for
free rather than fought.
- A reply's line 3 shows only the tags its thread does not have. The full
per-message set was rejected on measurement, not taste: of 48691 messages in
the user's database, 7 carry unread and 75 carry flagged, and both are
already shown as the sender's weight and the mark on line 2. Everything else
is applied per thread and identical on every message in it, so full sets
would render blank on nearly every reply and identical chips on the rest.
The design is a net removal. ThreadListView::paintEvent, the tag strip's band
arithmetic, SubjectDelegate, RowStyleDelegate, the five Column enumerators and
the decorative header all go; one CardDelegate paints the whole card. That
retires the two bug classes CLAUDE.md documents for the strip, a deleted row cut
in half and every other row showing a bare stripe, both of which existed because
the strip spanned cells it did not own.
The column header was decorative, so a sort dropdown adds a feature rather than
replacing one. Two entries only, newest and oldest, passed to notmuch. Sorting
by sender or subject would have to happen in the model after results arrive,
which fights the batching that makes a 10k-thread query paint immediately.
Item 51 is marked resolved by 53 rather than left as separate work.
|
|
Both backlog entries stated a cause that measurement contradicted, and
both would have misled the next reader into fixing the wrong thing.
Item 55 blamed the thread view's size hint, computed as the sum of its
fixed column widths, and placed the fault on first run. The hint is
256px, not 886: a QTableView does not put its column sum in its size
hint, so that mechanism never applied. The trigger is the restore, in a
window narrower than the one the position was saved in.
Item 58 claimed the zoom range is unenforced and the first render
unusable. MessageView::clampZoom() has always enforced exactly the
README's 0.5 and 3.0; only the report was missing.
|
|
A splitter position is saved in pixels, so one saved in a wide window
does not fit a narrower one: QSplitter::restoreState() honours the first
pane's saved size verbatim and gives the second whatever is left. A real
1285/1252 split restored into a 1136px window left the message pane 29px
wide, a sliver of rendered mail beside a full-width thread list. The
wider the window ever was, the worse the next narrower session.
Fixed with a minimum width on the pane and setCollapsible(1, false),
which covers the restore and the equivalent drag. A restore-time repair
running from showEvent() was written first and deleted: with the floor
in place it was mutation-tested to be redundant, since the minimum width
constrains restoreState() as much as it constrains a drag.
The floor is 300px rather than a bare "visible" width, because it is
reached only when a position does not fit and should land somewhere mail
is readable; at 200 the placeholder's own text wraps every few words.
The test asserts against the pane's own minimumWidth() rather than a
repeated literal, with a guard on the floor itself so it cannot pass
against a lowered one.
Note for later work in test_mainwindow: the offscreen platform chooses
the window width itself and has been seen to choose differently between
two runs of the same binary (1181 and 779), and it ignores resize(),
setFixedWidth() and a resize of the splitter on a shown window. Any
assertion on a pane ratio, or on the second pane's pixels, is measuring
that choice rather than this code.
Backlog item 55, whose recorded cause blamed the thread view's size hint
and first-run layout. Measured, that hint is 256px, not the 886 the item
computed from the column widths, and a freshly built window splits
correctly; the entry has been corrected in place.
|
|
The documented 0.5 to 3.0 range was already enforced, by
MessageView::clampZoom(), so message_zoom = 500 rendered at 3.0 rather
than unusably. What was missing is the report: the key parses, so
nothing ever told the user that the value in their file is not the value
on screen.
Reported rather than clamped a second time. MessageView owns the bounds
and does the work; a copy of the range in Config would be free to drift
from the one that matters, so config.cpp reports against kMinZoom and
kMaxZoom directly. This is where it differs from toolbar_icon_size,
which has no widget-side enforcement to defer to.
Backlog item 58, whose recorded cause was wrong on this point and has
been corrected in place.

The repo reached v0.12.0 with fourteen tags and zero GitHub Releases,
because every release had stopped after commit, tag and push. The user
noticed and asked for the backfill, then asked that it not happen again.
Records the whole procedure rather than the missing step alone, since
nothing had written it down: changelog section, version bump, signed
tag, push to both remotes, then `gh release create` with the body taken
from that version's changelog section rather than composed fresh.
Also records that the version choice follows semver on the user-visible
surface pre-1.0, which is why 0.12.0 was minor rather than patch, and
that the stale SlackBuild version is deliberately not part of this.

One fix: Archive and Mark all read shipped 0.12.0 sharing an icon,
which the same release's toolbar change made visible by removing the
text labels that had been disambiguating them.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
|

Item 59, reported by the user against 0.12.0. Archive and Mark all read
both used `mail-mark-read`, so with the toolbar following a desktop set
to icon-only the two buttons were indistinguishable, despite doing
different things: archive removes `inbox` from the selection, mark all
read removes `unread` from the whole view.
Introduced by item 56 in the same session. `archive` had that name from
before, when only eight actions carried icons, and item 56 assigned it
to `mark_all_read` as well without checking the table for duplicates.
`mail-archive` is also the more accurate name, since `mail-mark-read`
describes read state rather than archiving.
The test asserts the class rather than the reported pair: a hand-written
table of twenty-four names has more plausible duplicates in it, so
noTwoActionsShareAnIcon compares every action against every other. It
compares cacheKey() rather than the theme name, because two different
names resolving to the same art are equally ambiguous on screen, and it
guards on every action having an icon first, since on a theme that
resolves nothing the comparison loop would never run and pass vacuously.
Mutation-checked with a different collision.
Item 56's own probe is what let this through: it verified every name
resolves to non-null art, which is true of two names resolving to the
same art. Resolving and being distinguishable are separate properties.
The replacement was picked by rendering both at 24px and comparing the
images.

Collects the per-account sync, the cron-sync indicator fix, and the
toolbar and icon work that had been sitting unreleased since 0.11.0.
A minor bump rather than a patch: two user-visible behaviours changed.
The Flag action is now called Important, and the toolbar follows the
desktop's own button style instead of always showing text beside icons.
Both are documented under Upgrading, along with the saved-query label
that a user may want to rename to match.

Follow-up to item 56. With the toolbar now following the desktop's
button style, an "icon only" desktop makes the icon the whole control,
and this style reports PM_ToolBarIconSize as 16px, which is a small
target for a button with no text beside it.
A [general] toolbar_icon_size key, 16 to 64, defaulting to 24 rather
than to the style's own metric. Setting it to 16 restores the theme's
value.
Clamped and reported, unlike message_zoom, which documents a 0.5 to 3.0
range in the README and enforces none of it. Both ends here break the
UI that would be used to fix them: too small is an invisible icon, too
large is a toolbar taller than the window.
The unenforced message_zoom range is recorded as item 58 rather than
fixed here, since it is a separate defect that predates this change.
Also documents in the README that saved-query button labels are the key
names from the user's own [queries] section, which is why the "Flagged"
button still read that way after the action was renamed: it is a user's
query name, not a string this code owns. The sample config now shows
`Important = tag:flagged` to teach the wording the UI uses.

Items 56 and 57, done together because both touch the action registry.
56. The complaint was inconsistency, not absence: eight of twenty-four
actions had themed icons, so two adjacent entries in one menu disagreed
and the toolbar laid out an empty slot for the other sixteen. The
themeIcons table now covers them all. The fifteen names added were
probed against a live icon theme first rather than taken from the
freedesktop spec on faith, and the existing null-icon guard still lets a
theme that lacks one fall back to text.
The second half of the note asked that buttons honour the desktop's
"Icon only" setting. They could not: the hardcoded setToolButtonStyle
overrode it whatever the user had chosen. It now reads
SH_ToolButtonStyle. Dropping the call entirely was tried and rejected,
since a bare QToolBar defaults to ToolButtonIconOnly rather than to the
platform hint, which ignores the setting just as thoroughly the other
way. This is a visible change: on a desktop set to "Icon only" the
toolbar now shows icons without text.
57. "Important" over "Starred", the user's pick; the Message menu
already has "Mark &spam", so "Starred" would have needed an accelerator
from inside the word. Changed the action text, its status tip, the undo
description and the star column's tooltip, which still read "Flagged".
The tag stays `flagged`. It is wire format that neomutt, the user's
saved queries and ThreadSummary::isFlagged() all read, and following the
label through to the tag would rewrite the mail store and desynchronise
every other tool over the same Maildir. The action name stays `flag`
too, since that is the key users write in [keys].
Four tests. everyActionCarriesAnIcon names every action missing one and
guards against passing on an empty list; it reported all sixteen before
the change. theImportantActionStillWritesTheFlaggedTag asserts on the
tag the model actually received, and mutating it to `important` fails
that test plus two pre-existing held-edit tests.
Also adds the changelog entry for the cron-sync indicator fix, which the
commit that made it omitted.

Two notes added since this morning's pass, both presentation.
56: icons are inconsistent across the interface. The mechanism is not
missing, it is partial: the themeIcons table covers eight actions and
about twenty others get nothing, so adjacent menu entries disagree. The
names are not the obstacle either, probed against this desktop's theme
and every name a full set would need resolves. The second half of the
note, that buttons should honour "Icon only", is a real override: the
hardcoded setToolButtonStyle defeats the desktop's own setting.
57: rename the Flag action to Important or Starred. Label only. The
notmuch tag stays `flagged`, since it is wire format that neomutt and
the user's saved queries also read. The star glyph already ships in the
list column. Recorded that "Important" can take a free accelerator while
"Starred" collides with Mark &spam.
The first draft of 56 claimed there were no icons at all, which was
wrong: it missed the table at mainwindow.cpp:902 by grepping for the
call site rather than reading the setup. Corrected before commit.

Item 54. A sync fired by the user's cron carries tag edits to the mail
store exactly as a local one does, but only onSyncFinished() cleared the
pending state, so the indicator kept reporting work that had already
shipped and the exit prompt asked to sync for it. Verified against a
real cron run: 31 changes, cleared with no manual sync.
The window cannot see an external run's exit status, and /proc/locks
carries no outcome. It does not need to: mailsync.sh already ends every
run with a "RUN END ... status=OK" banner in its log, which outlives the
process that wrote it. MailSync::lastRunOutcome() reads a bounded tail
of that file and takes the last completed marker, so no change to the
script and no optimistic guessing were needed.
Only a definite OK clears anything. A failed run, a missing or
unreadable log, and a State::Unknown lock reading all leave the count
alone: over-reporting costs a redundant sync, under-reporting costs the
user their edits.
m_editedAccounts is drained in the same place, before flushHeldEdits()
and matching the local path's ordering. Item 49 uses it to choose which
mbsync channels a run syncs, and a count that reached zero while the set
stayed full would look correct and still sync the wrong channels.
The log path comes from a new optional [sync] log key, defaulting to
where the script writes, so a test never reads the developer's own log.
Two notes on the verification, both recorded in the backlog:
- A timing probe endorsed a tail read that was not happening. The
first version of the huge-log test required the call under 100 ms
and passed with the seek deleted, because reading 10 MB is fast
either way. Replaced with an assertion on content.
- Every fixture was invented and the first batch had the wrong
timestamp format, since the script uses date -Iseconds. The tests
passed anyway, because the parser keys on the prefix and the status
token. One test now builds the banner the way the script does.
The before-flushHeldEdits ordering has no test: without a held lock the
flush is a no-op, so both orderings pass.

The backlog is downstream of the user's Obsidian notes and had drifted.
Three notes had no entry; two became items and one turned out to be a
question with an answer already in the tree.
54, a defect: edits applied before a cron sync still counted as pending.
The count is cleared only in the local sync-finished handler, so a run
the window did not start left the indicator claiming work that had
already shipped, and the exit prompt asked to sync for it. Adjacent to
item 49, whose account set goes stale the same way.
55: in a window narrower than the thread view's column widths there is
no space left for the splitter's stretch factor to distribute, so the
message pane collapses to nothing on first run.
The third note asked whether a build can skip the tests. It can:
QTMAILDIR_BUILD_TESTS=OFF, which the SlackBuild already passes.
Causes verified in the code rather than copied from the notes.

The work for item 20 lives on the branch item-20-message-rows, parked and not
merged while the user explores a layout other than the table. Without these
documents on master the session-start backlog read would miss item 53 entirely
and item 20 would still read as unspecified, so the next session would either
re-ask a question already answered or start designing against a rejected design.
Docs only. No code from the branch is merged here, and the entries say so in
three places: a note above the status table, item 20's own section, and a banner
on the plan document telling a future agent not to execute it again.
File and line references were checked against master rather than copied. Item
53's citation of the column-grid cause pointed at threadlistmodel.cpp:275-283,
which on master is unrelated font handling; it now names the branch and the
function instead of a line range that would send a reader to the wrong code.
CLAUDE.md and CHANGELOG.md were deliberately NOT brought across. Both describe a
QTreeView and features master does not have, and a CLAUDE.md that misdescribes
the architecture is worse than one that is merely out of date.
|

printf does, and the habit transfers silently. In generated CSS it is
quietly destructive: a percentage written %% reaches the browser malformed,
and a browser drops that one declaration and renders the rest, so the pane
still paints and nothing looks broken. The 0.11.0 placeholder lost its
mask, its glow and both radial gradients this way.
Records the review lesson alongside it, which generalizes further than the
rule: a geometry probe endorsed that layout because it measured only
properties carrying no percentage. A probe that cannot see the thing that
breaks reports success forever.

A sync ran mbsync -a regardless of what changed, so tagging mail in one
account fetched all of them. The account set was not a parameter anywhere
on the path: MailSync::start() took no arguments and the script hardcoded
-a, so nothing between a tag edit and mbsync carried which account changed.
Track which accounts have edits and pass their mbsync channels through to
the script, which now takes channel names and falls back to -a when given
none. An empty set means all accounts, per the request: a sync with nothing
pending is a fetch, and narrowing that to wherever the last edit landed
would quietly stop collecting mail everywhere else.
The channel is a new optional per-account key rather than the section key.
The two names genuinely diverge, because a QSettings section key may carry
dots that the channel does not, and mbsync treats an unknown channel as
fatal rather than skipping it, so key-as-channel would fail those accounts'
syncs outright rather than degrade. It defaults to the key, so accounts
whose two names already agree need no config change.
The edited-account set is deliberately not netted the way the pending-edit
map is: that map tracks the index, where a tag removed and re-added leaves
nothing outstanding, while this tracks the mail store, where both writes
have already renamed files that mbsync still has to propagate. It is also
snapshotted before flushHeldEdits(), which inserts into it synchronously
rather than on a queued reply, so a successful sync cannot clear accounts
whose edits it never carried.
Closes item 49.

The empty message pane now carries the application's own identity and the
counts worth knowing, and Escape finally does what it does everywhere else.
Collects the placeholder pane, the Maildir overview, the Escape change,
and the thread-list work that had been sitting unreleased since 0.10.0.
|
|
Nothing in the UI reported database-level facts: every query gave a
thread count for that query, and nothing said how much mail there is
overall. A dialog under Help now shows messages, threads and tags from
notmuch, plus the account list from config, since notmuch does not model
accounts at all.
A separate worker call rather than a reuse of requestCounts, which counts
threads to match the row count of a query. This counts messages, which is
what a user means by "how much mail is in here". The test pins 4 messages
in 3 threads against the fixture and fails if they are ever made equal,
so routing both through one count cannot pass unnoticed.
Every field starts at -1 and renders as "unknown" when notmuch could not
answer it. Printing 0 would say the Maildir is empty, and telling someone
their mail is gone is the worst way to report an index that failed to
open.
The dialog opens showing "Counting..." rather than blocking, since
counting every message is not free on a large database. That makes two
lifetimes matter: the reply can arrive after the dialog is closed, so the
label is a QPointer, and the dialog can be closed and reopened while a
count runs, so a generation counter drops the older answer. The test
drains DeferredDelete before firing the late reply, because close()
deletes through deleteLater and without that the dangling case is never
actually reached.
