Round 3: lane 1's NITs on 29083a5f, taken here

Lane 1's re-review of 29083a5f was provisionally READY, with no MUST and no SHOULD, and two NITs (#889 issuecomment-6252129372). Both are taken in 32a5899feafde7b3ac6f5360157822b1d7556d91, one commit on 29083a5f, pushed as a fast-forward.

item	what changed	test row	mutant
NIT 1	STAGED_AT quoted one of git's two refusals. Measured on git 2.43 in seven states, each exit 1. Git says "the following file has changes staged in the index" where what is on disk matches what is staged: the clean git mv, an empty directory, and a checkout moved to HEAD~1 and added. It says "... has staged content different from both the file and the HEAD" where it differs too: a commit or an untracked file in the moved checkout, a directory holding a file, and a file. The clause and _staged_over's docstring now quote both.	two rows that print the second refusal (git-mv-and-a-commit-in-it, a-directory-holding-a-file); each refused row checks that the text quotes the words git printed	r3-NIT1-staged-in-the-index-alone: killed: 5 failed, 2 passed; r3-NIT1-different-from-both-alone: killed: 5 failed, 2 passed
NIT 2	No code change: a row. A hand mount committed with its section, its checkout moved to HEAD~1, then git add: HEAD records another commit there.	head-records-another-commit, which expects the clause	lane 1's "HEAD records nothing" mutant: killed: 1 failed, 6 passed

The round-2 SHOULD test now has 7 rows. Its four round-2 mutants were run again on these bytes, and each was killed.

Round 2: lane 1's re-review of #889, taken here

Lane 1 found 3b15de03 NOT READY on one new MUST, a regression round 1 brought in (#889 issuecomment-6250664740). Every round-1 item, the bootstrap.py half and the merges were READY. Every item is taken in 29083a5f2d9f812b8640790d2dba6cb9c9301193, one commit on 3b15de03, pushed as a fast-forward. Each Before is 3b15de03 and each Now 29083a5f, measured with lane 1's probe.

item	what changed	test row	mutant
MUST 2 (a regression)	SPARE mounted by hand at members/IRQS, then git rm --cached members/IRRS or a plain git rm members/IRRS, the file deleted. Before: round 1 counted the hand mount's git rm as a write (Report.wrote), though it writes nothing into a file that is gone, so the removal wrote IRRS's section key by key "in the file a line above put back", which no line had. Committed, HEAD's .gitmodules held that one section, and the gate found member-gitmodules-absent in every mode. Now: _section_back asks Report.put_back, and Report.wrote only with the file on disk. The removal puts the file back itself, as round 0 did: git checkout -- .gitmodules, or HEAD's after a plain git rm. Why this fix: it composes with C1's single put-back. With the file gone, any finding that writes into it must put it back first, and the first to do so records that, so put_back alone says a file is there to write into, whichever writer came first. A write with no put-back writes into no file, so it is ignored at the one place that reads it, for every writer, not only the hand mount. Lane 1's other fix, a put-back before _keys_back, would do again what the gone-file branch below already does, choosing the index's file or HEAD's by wanted.	test_round2_must_2_a_hand_mount_s_git_rm_writes_nothing_in_a_gone_file[cached] and [plain]: the lines in every mode; typed and committed, status clean, HEAD gives both members, the gate passes in every mode, a plain clone checks both out	r2-MUST2-wrote-asked-while-gone (round 1's report.put_back or report.wrote): killed: 2 failed
MUST 2: every other writer	Re-checked in the same state with lane 1's probe, each writer then each removal kind, the file deleted (16 states). The value finding, the move, absent and url-absent put the file back and record it. Path-twice and path-unnamed read only the work tree's file, so they find nothing while it is gone. The key-by-key lines follow a put-back. So a write with no put-back, with the file gone, was the hand mount's alone. 14 of the 16 type to a passing gate. The other two are as on 8ea0c44e, and are listed under "What it cannot tell": a section no row names, and a hand mount with its own section.	the probe (not committed)	none
SHOULD (a follow-up is fine)	git mv members/IRRS members/IRRS2, staged. Before: the hand mount's git rm -- members/IRRS2 exits 1 (the following file has changes staged in the index), as on main, where the text said only that it "refuses while its checkout holds changes". Now: the sentence only. Where the index stages the gitlink at a commit HEAD does not record there, and anything is on disk at it, an empty directory too (_staged_over), the text adds ", and while the index stages it at a commit HEAD does not record there, as it does here (the following file has changes staged in the index, exit 1),". Measured: git takes such a gitlink where nothing is on disk. The line itself is not fixed, because -f would take the checkout's changes that its refusal protects. Listed under "What it cannot tell", for #936.	test_round2_should_a_hand_mount_s_git_rm_says_it_refuses_a_staged_gitlink, four rows. The git mv state and a gitlink staged over an empty directory get the clause, and git rm exits 1. Nothing on disk, and a hand mount committed with its checkout, get none, and git rm exits 0.	r2-SHOULD-clause-never-said: killed: 2 failed, 2 passed; -always-said: killed: 2 failed, 3 passed; -asked-as-forced (_on_disk, which passes an empty directory): killed: 1 failed, 3 passed; -head-not-asked: killed: 1 failed, 3 passed
NIT (lane 1's MY3)	No code change: a row.	test_round2_nit_a_clone_at_no_case_variant_is_not_said_refused: git rm --cached members/IRRS, then IRRS cloned at tools/x and git add tools/x. The removal's finding is the same as with no clone there, in every mode. Typed, the clone stays untracked, the gate passes, and a plain clone checks both out.	lane 1's MY3 (clones at any path): killed: 1 failed, 1 passed

Run with this round's test file, 3b15de03's two scripts give 4 failed and 54 passed: both MUST 2 rows and the SHOULD's two clause rows fail. 8ea0c44e's give 17 failed and 41 passed: round 1's 15 and the SHOULD's two clause rows fail. The MUST 2 rows pass on 8ea0c44e, since round 1 brought that fault in. The NIT's row passes on both, since MY3 is a mutant, not a fault.

Found, not fixed (for #936): a member mounted by hand with git clone and git add, whose .git is a directory and which no section gives. The hand mount's git rm -- members/IRQS dies there with fatal: could not lookup name for submodule 'members/IRQS' (exit 128), as on main. It is listed under "What it cannot tell".

Round 1: lane 1's review of #889, taken here

Lane 1 found 8ea0c44e NOT READY (#889 issuecomment-6249673233). Every item was taken in 3b15de03, one commit on 8ea0c44e:

• MUST 1 (a regression): with the file gone and nothing put back, the first removal puts back HEAD's file where the index's lacks a section another staged removal needs (P4), and the key-by-key lines end with git add -- .gitmodules (P5).
• SHOULD 1: Report.wrote, set by every finding that writes the file: no removal puts HEAD's file back over such a write, and its section is written back key by key, leaving out a value git dies on.
• SHOULDs 2 and 3: a clone of its own at a case variant is said to be moved out whole, and a checkout git mv moved anywhere is named by its .git file.
• SHOULD 4 and NITs 1 to 6: the docstrings, a symbolic-link row, -f said per variant, updated_none asks nothing of the rows, "NOTHING UPDATED" under no row, and a row for MX1.

On 8ea0c44e's scripts, round 1's file gave 15 failed and 36 passed. The rows and mutants are under "Tests" and "Mutants".

What changed and why

Milestone v1.1.1: a DRAFT on main. It lands after #882 (#878), which has landed as 8148a38; see "Lands after #882 (#878), which has landed as 8148a38". This PR fixes the five lines (C1 to C5) that rv876's review of #876 found in the family holder's two pinned scripts, templates/family-root/scripts/validate-family.py and templates/family-root/scripts/bootstrap.py:

• remedies that undid each other, or refused, when typed as printed;
• a checkout that git mv moved, which no finding named;
• family bootstrap ok printed beside git's exit 128.

Three more states of the same kind were found while doing it, and are fixed and tested here (see "Found beyond the issue"). Two stale docstrings in bootstrap.py are corrected (see "bootstrap.py's stale docstrings").

Lane 2's review of #882 found three SHOULDs and three NITs in the code this PR reworks (rv882, #882 issuecomment-6248061386). #882 lands at its reviewed delta, and all six are taken here; see "rv882's items on #882, taken here".

How it was measured. A probe, tests/test_w879_probe.py, ran against this clone. It is an untracked scratch file and is not committed.

• Holder: a real one, tests/test_family.py's family fixture: two scaffolded members, IRRS (members/IRRS) and IRSS (members/IRSS), with a spare, IRQS.
• Environment: a stub gh that exits 97 first on PATH, GH_TOKEN=bogus, an empty GH_CONFIG_DIR, GIT_CONFIG_GLOBAL an empty file, GIT_CONFIG_NOSYSTEM=1, GIT_SSH_COMMAND=false, and local remotes only. Git is 2.43.0.
• Each state:
  1. the gate in all three modes;
  2. every printed line typed as printed, in the order printed, split as a POSIX shell splits it and run with no shell;
  3. git status, then the commit;
  4. the gate again in all three modes;
  5. a plain clone, then git submodule update --init --recursive.
     For C5, bootstrap.py --skip-members ran instead.
• Before is validate-family.py: gitmodules-path-unnamed takes the gitlink at a section's path outside members/ out of the index before the section, and a gitlink there that no section gives is gitlink-unnamed, so the remedy typed as printed no longer leaves a gitlink at which a plain clone's git submodule update --init exits 128 while the gate passes (#878) #882's head 7d195075, whose two scripts main 8148a38 holds byte for byte. The same probe on the family root's bootstrap.py and validate-family.py: the credential advice and a member's exit code say what happened, and the gate's git rm --cached, guarded mv and section lines type as printed where they failed (#839) #876's head a7f6c569 gave the same lines.
• Now is 8ea0c44e, round 0's head, unless a passage says round 1 (3b15de03), round 2 (29083a5f) or round 3 (32a5899f), above, which change C2's sibling, C4's sentence and the hand mount's text and add what lane 1 found; every other line below reads the same on 32a5899f. 8ea0c44e is this PR's change, 445b1e55, restacked on main and merged with main c9ca9a45, which holds bootstrap.py: a .gitmodules blob with a line git cannot parse is read up to that line, as git reads it, and a parity test holds the value rules both family scripts write to one answer (#856) #877. The C1 to C4 lines are the same on 3b7b7567 (this commit before rv882's items were taken), on 445b1e55 and on this head. So are C5's, but for the bad-line state, which bootstrap.py: a .gitmodules blob with a line git cannot parse is read up to that line, as git reads it, and a parity test holds the value rules both family scripts write to one answer (#856) #877 changes (see C5).
• Spelling: <commit> is a gitlink's commit. "The file" is the work tree's .gitmodules. "Gone" means deleted from disk, or its deletion staged; each test runs both (GONE, from the family root's bootstrap.py and validate-family.py: the credential advice and a member's exit code say what happened, and the gate's git rm --cached, guarded mv and section lines type as printed where they failed (#839) #876's tests/test_family_head_lost_gitmodules.py).

C1. The wrong-case move's section line, with the file gone (_move_section, validate-family.py:770 on this head, from _move_context, :688)

The state: rv876's P5e. IRSS's gitlink is recorded only at Members/IRSS, HEAD's section gives that path (as a committed git mv leaves it), and the file is gone. For P5b, IRRS's url is also out of HEAD's section.

Before. In members mode the refusal is printed alone:

git rm -r --cached --ignore-unmatch -- Members/IRSS
git update-index --add --cacheinfo 160000,<commit>,members/IRSS
git config -f .gitmodules submodule.members/IRSS.path members/IRSS
git add -- .gitmodules

Typed and committed, HEAD's .gitmodules held one key: [submodule "members/IRSS"] path = members/IRSS, and IRRS's section was lost.

• The gate then found member-gitmodules-absent and member-gitmodules-url-absent in every mode.
• The plain clone exited 128: fatal: No url found for submodule path 'members/IRRS' in .gitmodules.

P5b, --no-members, with the file deleted:

• The move's lines printed first.
• member-gitmodules-url-absent followed with git checkout -- .gitmodules, which put back the one-key file the move had just staged, then its git config ... url.
• Committed, the gate found member-gitmodules-absent and member-gitmodules-url-absent in every mode.
• With the deletion staged instead, it printed git checkout HEAD -- .gitmodules. Committed, the gate found gitmodules-path-unnamed and member-gitmodules-absent.
• The plain clone exited 128 both ways.

Now. The move puts the file back first, from where git reads it, then writes its key. The sentence says: "put .gitmodules, gone from the work tree, back from {whose}, so that every other section stays, then ...". With the file deleted:

git rm -r --cached --ignore-unmatch -- Members/IRSS
git update-index --add --cacheinfo 160000,<commit>,members/IRSS
git checkout -- .gitmodules
git config -f .gitmodules submodule.members/IRSS.path members/IRSS
git add -- .gitmodules

With the deletion staged, the third line is git checkout HEAD -- .gitmodules.

In P5b, member-gitmodules-url-absent follows with its git config ... url alone and puts nothing back: one put-back serves both findings.

Typed and committed, all four states (P5e and P5b, each with the file deleted or its deletion staged) end the same way:

• HEAD keeps both sections;
• the gate exits 0 in every mode, and git status is clean;
• the plain clone exits 0 with IRRS and IRSS checked out.

C2. member-gitlink-removal-staged's put-back over an earlier write (_section_back, :2938)

The state: rv876's P5d. git rm --cached members/IRRS, IRSS's section out of HEAD's .gitmodules, and the file gone.

Before.

1. The absent finding put the file back (git checkout -- .gitmodules) and wrote IRSS's section.
2. The removal's lines followed: git reset -q -- members/IRRS, then git checkout HEAD -- .gitmodules. It had read "section taken" from the empty work tree, so its put-back took IRSS's section out again.
3. The commit failed: nothing to commit (exit 1).
4. member-gitmodules-absent came back in every mode, and the plain clone exited 128.

Now.

• The removal reads "section taken" from the file git reads.
• After an earlier finding put the file back, it puts nothing back (Report.put_back). Here that file gives IRRS's path, so its one line is git reset -q -- members/IRRS.
• Typed in order and committed, the gate exits 0 in every mode, and the plain clone exits 0 with both checked out.
• With the removal's finding alone and the file gone, it puts the file back itself, from where git reads it. It says so: "the second the .gitmodules gone from the work tree, from the index". With git rm --cached and the file deleted, the line is now git checkout -- .gitmodules, where it was git checkout HEAD -- .gitmodules. The index's file gives the section, so the result is the same. Where the file git reads lacks the section, the line is git checkout HEAD -- .gitmodules as before.

C3. A value finding, then a stray's git rm --cached (_check_gitlinks_named, :2129; _variant_remedy, :2244; _second_path_out, :2280)

The state: rv876's P5g. A committed update = None in IRRS's section, and a stray gitlink at Members/IRRS staged with nothing on disk.

Before. The value finding's git config -f .gitmodules --unset-all submodule.members/IRRS.update left the file with changes not staged. The stray's line then failed with exit 128:

git rm --cached -- Members/IRRS
fatal: please stage your changes to .gitmodules or stash them to proceed

After the commit, the gate still found member-gitlink-unnamed and git status read D Members/IRRS. The plain clone exited 128: No url found for submodule path 'Members/IRRS'.

Now. In every mode, the stray's text opens with #878's sentence, with rv882's NIT 3 clause: "Stage .gitmodules with the first line, which stages every other change in it too, since git rm refuses to take any gitlink out of the index, -f or not, while .gitmodules holds changes not staged (please stage your changes to .gitmodules or stash them to proceed, exit 128), as lines printed above may leave it or as it stands, then take it out of the index alone ...". Its lines:

git add -- .gitmodules
git rm --cached -- Members/IRRS

Typed in order and committed, the status is clean, the gate exits 0 in every mode, and the plain clone exits 0 with both checked out. With no value finding before it (the control), the stray prints its one line as before.

C4. The checkout git mv moved, never named (_moved_said, :3050, in _removal_staged_said, :3021; _moved_checkouts, :2918)

The state: git mv members/IRRS Members/IRRS, staged. rv876 measured three variants of it, and each is run here:

• the moved checkout clean;
• a commit made in it;
• an untracked file in it.

Before. The three findings' lines, typed as printed:

• member-gitlink-unnamed's git rm --cached -f -- Members/IRRS;
• member-gitlink-removal-staged's git reset -q, git checkout HEAD -- .gitmodules and git submodule update --init --recursive -- members/IRRS.

After typing, the gate passed in every mode, but git status read ?? Members/. No finding said what that directory is.

Now. Each of the three variants types to the same end. member-gitlink-removal-staged says, before its last line:

The checkout git mv moved to Members/IRRS stays there, untracked, and family.py add refuses it as family-members-dir-variant: its .git file names the member's store under this holder's .git/modules/ by a path relative to it, and its commits are kept there whatever becomes of the checkout, so only what is not committed is in the checkout alone, which git -C Members/IRRS status shows. Delete it by hand once nothing only it holds is needed, before the last line: that update points the store at members/IRRS, after which git -C Members/IRRS status reads members/IRRS instead.

The sentence follows the closing sentences of family.py add (#828, #865). It is said only where no checkout is at the row's path. Since round 1 it is said of any index gitlink whose .git file names the member's store, at any path, with the family.py add clause for a case variant alone (lane 1's SHOULD 3), and a case variant whose .git is a directory, a clone of its own, gets the wrong-case move's clone sentence instead (SHOULD 2). The tests assert the sentence, then git -C Members/IRRS status before the update, which shows the untracked file or the commit's state.

C5. family bootstrap ok beside git's exit 128 (bootstrap.py: unfetchable, :871; fetch_members, :209; the new updated_none, :949)

The state: every member checked out, and git's update exits 128. That happens in two ways:

• git's init dies at a gitlink it has no url for:
  • a bad line committed after the first section of HEAD's .gitmodules, with the file gone (the issue's state);
  • a gitlink outside members/;
  • a stray;
  • a hand mount;
• or a .gitmodules that a merge left unmerged.

Before. For every stop, bootstrap exited 0 and printed:

  FETCH INCOMPLETE (git exit 128) using credential source 'none':
  If the members are PRIVATE, set SHAPE_LEGS_TOKEN (...) or export an App-minted SHAPE_LEGS_APP_TOKEN, then re-run. What did arrive is bootstrapped below.
family bootstrap ok

The unmerged file gave the same, without the advice.

Now. Bootstrap exits 1 and gives no credential advice. For the gitlink outside members/:

  FETCH INCOMPLETE (git exit 128) using credential source 'none':
  NO MEMBER UPDATED, and not for want of a credential: git stopped at vendor/IRQS, a gitlink it has no url for. No row names vendor/IRQS and no clone can check it out: `git rm --cached -- vendor/IRQS` takes its gitlink out, then commit that.
family bootstrap FAILED: vendor/IRQS (git stopped at it)

• The stray and the hand mount get the cure `python3 scripts/validate-family.py --no-members` names each gitlink in members/ that no row names, and the commit that cures it.
• The unmerged file ends git reads no .gitmodules while a merge leaves it unmerged. Resolve the merge in .gitmodules and `git add .gitmodules`, then run this again. and family bootstrap FAILED: .gitmodules (git cannot read it).
• With every member checked out and git exiting 0 (the control), the run still prints every member and leg fetched and family bootstrap ok.

How it works:

• unfetchable no longer returns before init_stop when no row is left.
• updated_none says why git updated no member: file_reason (unmerged, refused, unreadable, as row_reason asks them), else the stop.
• fetch_members fails on that through cures, which now takes it as whole, a tuple of one reason or none, so cures gains no branch (rv882's SHOULD 3).

The issue's own state, and #877. A bad line after the first section, with the file gone:

• Git stops at members/IRSS: error: bad config line 4 in blob ... and fatal: No url found for submodule path 'members/IRSS'.
• On 445b1e55, before bootstrap.py: a .gitmodules blob with a line git cannot parse is read up to that line, as git reads it, and a parity test holds the value rules both family scripts write to one answer (#856) #877, bootstrap failed but named members/IRRS: git config --blob refused the whole blob, so init_stop saw no section at all.
• On this head, with bootstrap.py: a .gitmodules blob with a line git cannot parse is read up to that line, as git reads it, and a parity test holds the value rules both family scripts write to one answer (#856) #877's squash merged from main, it names members/IRSS, with bootstrap.py: a .gitmodules blob with a line git cannot parse is read up to that line, as git reads it, and a parity test holds the value rules both family scripts write to one answer (#856) #877's cure: "git checkout --ignore-skip-worktree-bits -- .gitmodules puts back the index's .gitmodules, which git read only up to a line it cannot parse: mend it by hand (git config -f .gitmodules --list says where it breaks), and commit it."
• With the bad line before the first section, it names members/IRRS, as git does, with the same cure.

The brief kept C5 independent of #877's blob read, so the test asserts the failure and a named stop of either member.

Found beyond the issue

Each was approved by lane 4's coordinator, is fixed here, and has a test row.

• C1's sibling: member-gitlink-absent's own section lines (validate-family.py: a staged git rm is named again and fails retyped, the member-gitlink-absent remedy ends in a refused add, a shape-pin row with no path: reads None, and #639's mv orphans a live checkout and is stated by OS #681), with the file gone (_gitlink_put_back, :550).
  • The state: IRRS taken out by a plain git rm and committed, then the file gone.
  • Before: the refusal's git config -f lines made a file of IRRS's section alone. Committed, HEAD lost IRSS's section, and --no-members found member-gitmodules-absent.
  • Now: the second line is git checkout -- .gitmodules (or HEAD's), said as "the first of which puts .gitmodules, gone from the work tree, back from {whose}, so that every other section stays". HEAD keeps IRSS's section. After the update the members mode asks for, the gate passes in every mode.
• C2's sibling: a plain git rm, beside another absent finding, with the file gone (_section_back).
  • The state: git rm members/IRRS takes IRRS's section out of the work tree's file and stages that; IRSS's section is out of HEAD's; the file is then deleted.
  • Before:
    1. The absent finding put back the index's file, which lacks IRRS's section.
    2. The removal's git checkout HEAD -- .gitmodules then took IRSS's new section out again.
    3. The commit had nothing to commit, and member-gitmodules-absent came back.
  • Now: the removal writes IRRS's section back into the file put back, key by key as HEAD has it. The update dies No url found without that section. Since round 1 the section is staged too (lane 1's MUST 1), and the text reads: "the first its gitlink, the second to the third the .gitmodules section git rm took out, key by key as HEAD has it, in the file a line above put back, the fourth that section in the index, staging .gitmodules whole, which stages every other change in it too, the fifth its checkout: commit .gitmodules then, with what the lines above write in it, and nothing else is left to commit." Typed in order and committed, the gate passes and the plain clone checks both out.
• C3's siblings: the hand mount's git rm -- and the wrong-case move's git rm -r --cached, after a value finding's lines (_mounted_by_hand, :2460; _move_context and _wrong_case_move, :868).
  • Before: both exited 128 with the same please stage your changes message. After the move's failure, its update-index left the gitlink at both paths.
  • Now: each comes after git add -- .gitmodules, using validate-family.py: the gitmodules-path-unnamed remedy takes out the section of a submodule no row names and leaves its gitlink, so a plain clone's git submodule update --init exits 128 while the gate passes #878's sentence.
    • The hand mount says "stage .gitmodules with the second, which stages every other change in it too, since git rm refuses ..., take it out with the third ..., then mount it with the fourth".
    • The move says "with the next two lines".

bootstrap.py's stale docstrings

Two passages still said that no mode of the validator reads a gitlink outside members/. #878 made every mode find one (gitlink-unnamed).

• The (a) paragraph of the module docstring now reads "git rm --cached takes out one outside members/, as every mode of the validator says (validate-family.py: the gitmodules-path-unnamed remedy takes out the section of a submodule no row names and leaves its gitlink, so a plain clone's git submodule update --init exits 128 while the gate passes #878)".
• The cures docstring now reads "A gitlink outside members/ is taken out of the index, as every mode of the validator says (validate-family.py: the gitmodules-path-unnamed remedy takes out the section of a submodule no row names and leaves its gitlink, so a plain clone's git submodule update --init exits 128 while the gate passes #878)".

fetch_members', unfetchable's and (c)'s docstrings now say C5, and the module docstring has a paragraph on what the run said before.

rv882's items on #882, taken here

Lane 2's rv882 found #882 READY at c3f8fa54 with three SHOULDs and three NITs (#882 issuecomment-6248061386). #882 landed at its reviewed delta, and lane 4's coordinator moved all six here. Each one that changes behaviour has a test row; round 0's body gave each Before and Now in full.

• rv882's SHOULD 1 on validate-family.py: gitmodules-path-unnamed takes the gitlink at a section's path outside members/ out of the index before the section, and a gitlink there that no section gives is gitlink-unnamed, so the remedy typed as printed no longer leaves a gitlink at which a plain clone's git submodule update --init exits 128 while the gate passes (#878) #882, taken here: both of _stage_first's branches that print no git add are tested: (D) with the work tree's .gitmodules deleted, where a git add would stage the deletion, and with its removal staged, where it would stage the file over that removal. Code unchanged; rv882's two mutants are killed.
• rv882's SHOULD 2 on validate-family.py: gitmodules-path-unnamed takes the gitlink at a section's path outside members/ out of the index before the section, and a gitlink there that no section gives is gitlink-unnamed, so the remedy typed as printed no longer leaves a gitlink at which a plain clone's git submodule update --init exits 128 while the gate passes (#878) #882, taken here: gitlink-unnamed reads the paths from the file git reads where the work tree's is gone (_given_as_git_reads). (A) with that file gone is no finding in any mode, and the gate passes, as before validate-family.py: the gitmodules-path-unnamed remedy takes out the section of a submodule no row names and leaves its gitlink, so a plain clone's git submodule update --init exits 128 while the gate passes #878. Of rv882's two fixes, this one writes nothing, so it needs no put-back of its own.
• rv882's SHOULD 3 on validate-family.py: gitmodules-path-unnamed takes the gitlink at a section's path outside members/ out of the index before the section, and a gitlink there that no section gives is gitlink-unnamed, so the remedy typed as printed no longer leaves a gitlink at which a plain clone's git submodule update --init exits 128 while the gate passes (#878) #882, taken here: _check_gitlinks_named, _check_gitmodules_named, _check_gitlinks_registered, _move_context and _check_removals_staged are split into helpers (_gitlink_unnamed_said, _hand_project, _variant_remedy, _section_unnamed_said, _section_out, _index_around, _move_section, _rows_at_their_paths, _moved_checkouts), with no text change; cures takes whole as a tuple and gains no branch. Counted below.
• rv882's NIT 1 on validate-family.py: gitmodules-path-unnamed takes the gitlink at a section's path outside members/ out of the index before the section, and a gitlink there that no section gives is gitlink-unnamed, so the remedy typed as printed no longer leaves a gitlink at which a plain clone's git submodule update --init exits 128 while the gate passes (#878) #882, taken here: the two stale docstrings in bootstrap.py (see above).
• rv882's NIT 2 on validate-family.py: gitmodules-path-unnamed takes the gitlink at a section's path outside members/ out of the index before the section, and a gitlink there that no section gives is gitlink-unnamed, so the remedy typed as printed no longer leaves a gitlink at which a plain clone's git submodule update --init exits 128 while the gate passes (#878) #882, taken here: a staged gitlink's git rm --cached takes -f over anything on disk but an empty directory (_on_disk): git 2.43 refused the plain line over a directory holding a file and no .git, a file, and a symbolic link (exit 1), and took it over an empty directory and over nothing. The sentence says "over a checkout" where a .git entry is there, else "over what is on disk there, which is no checkout" (_held_as), in the wrong-case move too.
• rv882's NIT 3 on validate-family.py: gitmodules-path-unnamed takes the gitlink at a section's path outside members/ out of the index before the section, and a gitlink there that no section gives is gitlink-unnamed, so the remedy typed as printed no longer leaves a gitlink at which a plain clone's git submodule update --init exits 128 while the gate passes (#878) #882, taken here: STAGE_SAID, and the hand mount's stage sentence, say the git add "stages every other change in it too" (STAGE_TOO); validate-family.py: the gitmodules-path-unnamed remedy takes out the section of a submodule no row names and leaves its gitlink, so a plain clone's git submodule update --init exits 128 while the gate passes #878's STAGE_SAID constant in tests/test_family_unnamed_gitlink.py takes the clause.

Cognitive complexity. These counts come from a counter of sonar-python's published rules for S3776 (cc.py in lane 4's scratch). It counts:

• +1 plus the nesting level for if, for, while and except;
• +1 for elif and else;
• +1 for each run of like boolean operators.

Two settings were not certain, so each is counted both ways:

• conditional expressions, with and without a nesting increment ("lenient" and "nested" below);
• comprehension clauses ("strict" counts each one).

Sonar's own figures were not read. The tool gives rv882's hand counts of #882 exactly: lenient 15 and 18 for _check_gitmodules_named, and lenient 19 and 20 for _check_gitlinks_named. The limit is 15.

function	main 281df263	#882's 7d195075 (main 8148a38's scripts)	3b7b7567	this head
_check_gitlinks_named	19 / 21 / 29	20 / 22 / 30	21 / 23 / 31	8 / 8 / 13
_check_gitmodules_named	15 / 16 / 22	18 / 20 / 26	18 / 20 / 26	12 / 12 / 16
_check_gitlinks_registered	17 / 18 / 20	17 / 18 / 20	20 / 21 / 23	14 / 14 / 16
_move_context	13 / 13 / 18	13 / 13 / 18	16 / 16 / 21	2 / 2 / 4
_check_removals_staged	12 / 13 / 18	12 / 13 / 18	13 / 15 / 19	5 / 5 / 5
bootstrap.py cures	16 / 18 / 29	16 / 18 / 29	17 / 19 / 30	17 / 19 / 33, as on main c9ca9a45 with #877 (16 / 18 / 29 on 445b1e55)

Each cell reads lenient / nested / strict.

• No new or split function counts above 10 nested; the highest is _rows_at_their_paths, at 10.
• cures was above 15 on main already: 18 nested before bootstrap.py: a .gitmodules blob with a line git cannot parse is read up to that line, as git reads it, and a parity test holds the value rules both family scripts write to one answer (#856) #877, and 19 with it. This head leaves its count exactly as main has it, since refactoring it here would rewrite the lines bootstrap.py: a .gitmodules blob with a line git cannot parse is read up to that line, as git reads it, and a parity test holds the value rules both family scripts write to one answer (#856) #877 changed.
• Under "strict", _check_gitmodules_named and _check_gitlinks_registered are 16. To my knowledge, sonar-python does not count comprehension clauses.
• Round 1 (3b15de03), lenient / nested / strict: _check_removals_staged 3 / 3 / 10, _section_back 9 / 9 / 12, _keys_back 1 / 1 / 5, _moved_checkouts 2 / 2 / 8, _store 2 / 2 / 4, _names_store 4 / 4 / 4, _moved_said 3 / 4 / 7, _forced_over 2 / 2 / 4, _move_context 1 / 1 / 1, _check_gitlinks_named 9 / 9 / 14, _check_gitmodules_values 10 / 11 / 13, _check_gitmodules_paths 7 / 8 / 10, and bootstrap.py's fetch_members 12 / 13 / 17 and updated_none 2 / 2 / 2; the rest are as above.
• Round 2 (29083a5f): _section_back 10 / 10 / 13, _check_gitlinks_named 9 / 9 / 14, _mounted_by_hand 5 / 5 / 5, _forced 2 / 2 / 2, and the new _head_records and _staged_over 1 / 1 / 1.

Every site touched

Round 0's sites, each with its line on 8ea0c44e, are in the diff: the module docstring, Report.put_back, _file_put_back, _gitlink_put_back, the move's helpers (MoveContext, _move_context, _index_around, _move_section, _wrong_case_move, _first_line_flags), _forced, _on_disk, _held_as, _forced_said, _check_gitlinks_named and its helpers, _second_path_out, _mounted_by_hand, STAGE_WHY, STAGE_TOO, STAGE_SAID, _check_gitlinks_elsewhere, _given_as_git_reads, _check_gitmodules_named and its helpers, _check_gitlinks_registered, _check_removals_staged and its helpers, and bootstrap.py's fetch_members, cures, unfetchable, row_reason, file_reason and updated_none. Round 1's:

file	site	change
validate-family.py	round 1: Report.wrote, set in _check_gitmodules_values, _check_gitmodules_paths, _check_gitlinks_named (a hand mount's git rm), _move_section, _check_gitmodules_named, _check_gitlinks_registered and _section_back	lane 1's SHOULD 1
validate-family.py	round 1: _check_removals_staged (HEAD's file read once: wanted, refused), _section_back, _keys_back (new), STAGED_BACK (new), _removal_staged_said	lane 1's MUST 1 and SHOULD 1
validate-family.py	round 1: _moved_checkouts, _store (new), _names_store (new), _moved_said, _statuses and _unpushed (new, shared with _wrong_case_move)	lane 1's SHOULDs 2 and 3
validate-family.py	round 1: _forced_over (new, from _move_context), _wrong_case_move's and MoveContext's docstrings; the module docstring	lane 1's NITs 1 and 3
bootstrap.py	round 1: module docstring (a) and (c), fetch_members, NONE_UPDATED (new), updated_none	lane 1's SHOULD 4 and NITs 4 and 5
validate-family.py	round 2: _section_back and its docstring	lane 1's MUST 2
validate-family.py	round 2: STAGED_AT (new), _mounted_by_hand (staged_at), _check_gitlinks_named, _head_records (new, from _forced), _staged_over (new)	lane 1's SHOULD, round 2

Every finding and remedy in the plain states is unchanged; the control rows below pin that.

Tests

tests/test_family_holder_remedies_compose.py is new, with 61 tests: 35 in round 0, 16 in round 1, 7 in round 2 and 3 in round 3. Each one:

1. builds its state in tests/test_family.py's holder;
2. types every remedy as printed, in the order printed;
3. asks the gate in every mode;
4. makes a plain clone and runs git submodule update --init --recursive, which must check out both members (validate-family.py: the gitmodules-path-unnamed remedy takes out the section of a submodule no row names and leaves its gitlink, so a plain clone's git submodule update --init exits 128 while the gate passes #878's assert_a_plain_clone_checks_out_every_member).

A url a remedy writes is the one family.py add writes, on GitHub. The clone reaches the fixture's local remotes through it by a url.<base>.insteadOf for that one command (cloning, from #876's github_to).

rv882's NIT 2	4	tools/x staged over a directory holding a file, over a file, and over an empty directory (3); the wrong-case move over a directory holding a file (1)
lane 1's MUST 1	3	P4 (1); P5 with the file deleted and on disk (2)
lane 1's SHOULD 1	7	a removal after each writer, the file on disk: OTHER's section out of HEAD's, its url out, a value in OTHER's and in IRRS's own section, a section no row names, a hand mount with its section (6); gitmodules-path-twice's by-hand edit (1)
lane 1's SHOULD 2	1	a clone of its own at Members/IRRS; skipped where the disk folds case

lane 1's NIT 3	1	the move over two variants, a directory holding a file and a checkout; skipped where the disk folds case
lane 1's NIT 5	1	members: [] and a gitlink at vendor/IRQS
lane 1's NIT 6	1	a value in IRSS's section, git rm --cached members/IRRS, the file deleted
lane 1's MUST 2	2	a hand mount, then a cached or a plain removal, the file deleted
lane 1's SHOULD, round 2, and NITs 1 and 2, round 3	7	git mv members/IRRS members/IRRS2; a gitlink staged over an empty directory, and over nothing; a hand mount committed with its checkout; round 3: its checkout moved to HEAD~1 and added, a commit in the checkout git mv moved, and a gitlink staged over a directory holding a file
lane 1's NIT, round 2	1	a clone at tools/x

On #882's head 7d195075, whose scripts main 8148a38 holds byte for byte, with this file added: 26 failed and 9 passed. The nine that pass are:

• the four controls;
• the two "removal alone" rows whose line is unchanged;
• rv882's two SHOULD 1 rows, whose branches were right and untested;
• NIT 2's empty-directory row, whose line is unchanged.

Rounds 1 and 2 give their own counts on the head before each, above.

The helpers come from:

• the family root's bootstrap.py and validate-family.py: the credential advice and a member's exit code say what happened, and the gate's git rm --cached, guarded mv and section lines type as printed where they failed (#839) #876's tests/test_family_holder_bootstrap_texts.py, tests/test_family_head_lost_gitmodules.py and tests/test_validate_family_typed_states.py;
• validate-family.py: the gitmodules-path-unnamed remedy takes out the section of a submodule no row names and leaves its gitlink, so a plain clone's git submodule update --init exits 128 while the gate passes #878's tests/test_family_unnamed_gitlink.py and tests/test_validate_family_unnamed_mounts.py;
• tests/test_family_bootstrap_gate_order.py, tests/test_family_member_path.py, tests/test_family_remove_gitmodules.py, tests/test_family_dry_run.py and tests/test_family_add_refusals.py.

No helper is copied. One existing line changes: the STAGE_SAID constant in #878's tests/test_family_unnamed_gitlink.py, which pins the sentence whole, takes NIT 3's clause. Every test in that file passes with it (see "The run").

What it cannot tell

• The bad-line states hang on bootstrap.py: a .gitmodules blob with a line git cannot parse is read up to that line, as git reads it, and a parity test holds the value rules both family scripts write to one answer (#856) #877. On 445b1e55 alone, the issue's state named members/IRRS where git names members/IRSS. With the bad line before the first section, it said to write back a section that is there behind the line. bootstrap.py: a .gitmodules blob with a line git cannot parse is read up to that line, as git reads it, and a parity test holds the value rules both family scripts write to one answer (#856) #877 has landed, and this head, which merges it, names each stop as git does with bootstrap.py: a .gitmodules blob with a line git cannot parse is read up to that line, as git reads it, and a parity test holds the value rules both family scripts write to one answer (#856) #877's cure. A revert of bootstrap.py: a .gitmodules blob with a line git cannot parse is read up to that line, as git reads it, and a parity test holds the value rules both family scripts write to one answer (#856) #877 alone would bring the old words back; the failure itself does not depend on it. The gate refuses both states as gitmodules-unreadable in every mode.
• An unmerged .gitmodules now fails bootstrap where the gate passes. The gate reads HEAD's file. Git's update reads nothing from an unmerged one and exits 128, so no member was updated.
• init_stop models git's init; it is not git's own answer. Bootstrap now fails on a stop init_stop finds wherever git exits non-zero with every member checked out. A state where git exits non-zero for another reason, and init_stop predicts a stop git did not reach, would fail naming that gitlink. No such state was found or measured.
• Bootstrap still says ok beside an exit 128 this holder's records do not show (lane 1's SHOULD 4 on validate-family.py and bootstrap.py: the holder's remedies, typed as printed in order, put a .gitmodules gone from the work tree back once and never over another remedy's write, stage it before a gitlink's git rm and after a section written back, and name a checkout git mv moved before the update, and bootstrap fails where git's init in this holder stopped with every member checked out, so no remedy undoes another or exits 128 (#879) #889, B4 and B5). C5 fails where git's init in this holder stopped: at a gitlink this holder records with no url, or at an unmerged .gitmodules. With every member checked out, two other exit 128s still give the credential advice and family bootstrap ok, as on main:
  • B5: a gitlink committed in a member's own index with no url (No url found for submodule path 'members/IRRS/vendor/nested'); init_stop reads this holder's index alone.
  • B4: a gitlink of this holder's at a commit no remote holds (not our ref), bootstrap.py and validate-family.py: family bootstrap ok with no member checked out, an earlier row's member-uninitialized hiding a case-variant refusal, and member-gitlink-unnamed with no command under --no-members #648's credential skip.
    Telling either apart needs git's own words, or every member's index read; neither is done here. Named for a follow-up.
• The value finding puts back HEAD's file (bootstrap.py and validate-family.py: a .gitmodules value git dies on while reading the file fails make bootstrap naming the key, and the family gate names it, so update = None no longer ends family bootstrap ok (#648) #768; lane 1's NIT 1 on validate-family.py and bootstrap.py: the holder's remedies, typed as printed in order, put a .gitmodules gone from the work tree back once and never over another remedy's write, stage it before a gitlink's git rm and after a section written back, and name a checkout git mv moved before the update, and bootstrap fails where git's init in this holder stopped with every member checked out, so no remedy undoes another or exits 128 (#879) #889). Where the work tree's .gitmodules is gone, gitmodules-value-refused puts back HEAD's, whose value its lines take out, not the index's, which git reads there. A fix staged in the index's file is lost. The docstrings now say so; the behaviour is bootstrap.py and validate-family.py: a .gitmodules value git dies on while reading the file fails make bootstrap naming the key, and the family gate names it, so update = None no longer ends family bootstrap ok (#648) #768's.
• A section written back key by key goes at the end of the file, where git config -f puts a new section, so the committed .gitmodules can differ from HEAD's in the order of its sections (lane 1's SHOULD 3 state, for one). The removal's text now says to commit the file.
• A commit typed between two findings. Where an earlier finding says to stage and commit .gitmodules and a removal is staged, a plain git commit typed before the removal's lines records that removal too. The tests, as lane 1's probes, type every finding's lines first and commit once; no text here says to commit between findings, and none says not to.
• The member's store is found by HEAD's section name (_store): a section renamed by hand after git submodule add names a store the moved checkout's .git file does not, and that checkout is not named. No such state was measured.
• "and nothing is left to commit". member-gitlink-removal-staged says this of its own lines where they write nothing into .gitmodules (validate-family.py: the case-variant move back leaves .gitmodules naming the variant and has no --sparse, a staged un-registration passes the gate, and three findings print no remedy, one that dies, or a claim a recursive clone does not keep #762), as after an earlier finding that put the file back and gives its section (P5d). That finding's write is still to commit, and its own text says so. Where the removal's lines write the section back, they stage the file and say to commit it (round 1).
• Ordinals past the tenth read 11th, 12th and so on (_ordinal). No state here prints more than seven lines in one finding.
• A section no row names, with the work tree's file gone (rv882's SHOULD 2, the other half). gitmodules-path-unnamed reads the work tree's file. So (A) with that file gone passes the gate until the file is back, as it did before validate-family.py: the gitmodules-path-unnamed remedy takes out the section of a submodule no row names and leaves its gitlink, so a plain clone's git submodule update --init exits 128 while the gate passes #878; gitlink-unnamed no longer speaks there, since its words were false.
• A hand mount with its own section, then a staged removal, with the work tree's file gone (round 2). The hand mount's git rm cannot take its section out of a file that is gone. The removal then puts the file back, and the section comes back with it. After the commit the gate finds gitmodules-path-unnamed, as it did on 8ea0c44e. For validate-family.py (family root): after #889, three hand-mount git rm lines still fail when typed: a gitlink staged at a commit HEAD does not record, a hand mount with its own section while .gitmodules is gone, and a hand clone with no section (exit 128) #936.
• A hand mount's git rm over a gitlink staged at a commit HEAD does not record there (lane 1's SHOULD, round 2). This is the state after git mv members/IRRS members/IRRS2 is staged, or after a gitlink is staged over an empty directory. The line exits 1, as it does on main. The text now says so, but no line takes such a gitlink out. For validate-family.py (family root): after #889, three hand-mount git rm lines still fail when typed: a gitlink staged at a commit HEAD does not record, a hand mount with its own section while .gitmodules is gone, and a hand clone with no section (exit 128) #936.
• A hand mount cloned by hand (round 2). The state is git clone then git add, so the .git is a directory and no section gives the path. Its git rm dies with could not lookup name for submodule (exit 128), as it does on main. For validate-family.py (family root): after #889, three hand-mount git rm lines still fail when typed: a gitlink staged at a commit HEAD does not record, a hand mount with its own section while .gitmodules is gone, and a hand clone with no section (exit 128) #936.
• S3776 is counted here, not by Sonar. See "Cognitive complexity". SonarCloud's analysis of this PR is the check.
• Windows and macOS. CI is Linux only (ci: run the test suite on Linux only #597). The C4 tests, the move's NIT 2 test and round 1's SHOULD 2 and NIT 3 rows skip on a disk that folds case, and NIT 2's link row where no symbolic link can be made.
• Git versions. Only this host's git 2.43.0 ran. CI's git 2.55 was not run locally.

Choices for the reviewer

1. C3: git add -- .gitmodules before the git rm, the issue's first way, not the stray's line first.
   • The value finding prints first in every mode. Moving the stray's finding ahead of it would change the gate's printed order, which other tests read.
   • validate-family.py: the gitmodules-path-unnamed remedy takes out the section of a submodule no row names and leaves its gitlink, so a plain clone's git submodule update --init exits 128 while the gate passes #878 already settled the stage line for its own git rm (_stage_first, STAGE_LINE, STAGE_SAID). One rule now covers the stray, the hand mount, the wrong-case move and validate-family.py: the gitmodules-path-unnamed remedy takes out the section of a submodule no row names and leaves its gitlink, so a plain clone's git submodule update --init exits 128 while the gate passes #878's line.
   • The line is printed only where the file differs from the index's or a value finding edited it (_stage_first(root, edited)), so the plain states print what they did.
2. One put-back per run (Report.put_back).
   • The first finding, in printed order, that writes into a gone file puts it back. Later findings print no put-back.
   • Where the file put back lacks a later finding's section, that finding writes the section key by key (C2's sibling).
   • The writers, in printed order: the value finding (HEAD's file), the wrong-case move, the absent and url-absent findings, and the removal.
3. The file is put back from where git reads it: the work tree's, else the index's at stage 0, else HEAD's (the family root's bootstrap.py and validate-family.py: the credential advice and a member's exit code say what happened, and the gate's git rm --cached, guarded mv and section lines type as printed where they failed (#839) #876's _gitmodules_put_back).
   • A file deleted only from disk comes back from the index, keeping what is staged.
   • A staged deletion comes back from HEAD.
   • So with git rm --cached and the file deleted, the removal alone now prints git checkout -- .gitmodules where it printed HEAD's (C2, "Now").
4. C2's section by key, not a second git checkout HEAD. A second checkout would drop the earlier finding's write. Each key comes in HEAD's order, with HEAD's value, quoted with shlex.quote.
5. C4's sentence is in member-gitlink-removal-staged, before its update.
   • The update is the line that points the store at the row's path, so the sentence has to come before it.
   • The stray's own git rm --cached -f text, from the family root's bootstrap.py and validate-family.py: the credential advice and a member's exit code say what happened, and the gate's git rm --cached, guarded mv and section lines type as printed where they failed (#839) #876, is unchanged.
   • The words follow family.py add's closing sentences (family.py add: the move back of a member's gitlink points its section of .gitmodules back, sets aside first what the index holds in its way and puts back a member whose removal is staged, its closing mv is guarded and leaves a checkout to delete by hand, and --sparse follows the sparse rules, so no printed line leaves a section naming another spelling or un-registers a member (#761) #828, family.py add: a section astray beside its gitlink, a variant of a row's path under members/, a link or checkout in a move's way, an unmerged entry and a staged or unmerged .gitmodules are named first, so each remedy types clean (#840) #865).
6. C5 goes through cures with whole, and gives no credential advice.
   • credential_advice already says nothing where git stopped at a gitlink or read no .gitmodules (the family root's bootstrap.py and validate-family.py: the credential advice and a member's exit code say what happened, and the gate's git rm --cached, guarded mv and section lines type as printed where they failed (#839) #876). unfetchable now asks init_stop, so the advice drops out with no new branch.
   • The failure line names the gitlink, or .gitmodules (git cannot read it), as bootstrap.py and validate-family.py: a .gitmodules value git dies on while reading the file fails make bootstrap naming the key, and the family gate names it, so update = None no longer ends family bootstrap ok (#648) #768's line does.
7. C5 is independent of bootstrap.py: a .gitmodules blob with a line git cannot parse is read up to that line, as git reads it, and a parity test holds the value rules both family scripts write to one answer (#856) #877's blob read, as the brief asks. The cost is the stop's name in the one state above.
8. rv882's SHOULD 2: the paths are read from the file git reads, not put back first.
   • gitlink-unnamed prints only a git rm --cached, which writes nothing into .gitmodules, so a put-back of its own would only add a line.
   • Reading the file git reads makes the finding's words true as git reads them, and the one put-back of C1 and C2 is left as it is.
9. rv882's NIT 2: -f over anything on disk but an empty directory, not only over a directory that holds files.
   • Git 2.43 refused the plain line over a file and over a symbolic link at the gitlink's path too (measured), and took it over an empty directory and over nothing.
   • With --cached, -f touches no file.
   • A directory this user cannot list is taken to hold something.
10. rv882's NIT 2: the words.
    • "over a checkout" stays where a .git entry is there, so the texts the family root's bootstrap.py and validate-family.py: the credential advice and a member's exit code say what happened, and the gate's git rm --cached, guarded mv and section lines type as printed where they failed (#839) #876 and validate-family.py: the gitmodules-path-unnamed remedy takes out the section of a submodule no row names and leaves its gitlink, so a plain clone's git submodule update --init exits 128 while the gate passes #878 pin are unchanged.
    • Elsewhere the sentence says "over what is on disk there, which is no checkout".
    • FORCED_SAID, what -f does, is unchanged.
11. rv882's SHOULD 3: helpers, not a rewrite.
    • Each split moves the code as it was into a function of its own, and no printed text changes; the tests that pin the texts whole pass unchanged.
    • cures is left at main's count, as bootstrap.py: a .gitmodules blob with a line git cannot parse is read up to that line, as git reads it, and a parity test holds the value rules both family scripts write to one answer (#856) #877 also changes it (see "Cognitive complexity").
12. Round 1, MUST 1: both of lane 1's fixes, not one. The stage line ends every key-by-key group (P5 needs it: the move's git add comes before the removal's lines), and the first removal with the file gone puts back HEAD's where the index's lacks a section another staged removal needs (P4 then types as clean as c9ca9a45: no key-by-key lines at all, and git status clean).
13. Round 1, SHOULD 1: a flag set by the writers, not a scan of the printed text. Report.wrote is set beside each finding whose lines write .gitmodules or which says to commit it as it stands, including gitmodules-path-twice, whose remedy is by hand. A removal after one never prints git checkout HEAD -- .gitmodules; with no writer before it, it prints what it printed, so the plain states are unchanged (the C2 control row).
14. Round 1, SHOULD 1: a key HEAD's gives a value git dies on is not written back. Written back as HEAD has it, it would be gitmodules-value-refused again; the value finding's own lines, or its "stage and commit the work tree's .gitmodules", cure it.
15. Round 1, SHOULD 3 taken here, by the .git file. A checkout git mv moved keeps a .git file naming the member's store, wherever it went, so that, not the path's case, is the test. The store is named as git names it, modules/<name> in --git-common-dir with HEAD's section name; the file is read as git reads it. No git runs inside the checkout.
16. Round 1, SHOULD 4: reworded, B4 and B5 not fixed. Both need git's own words, or every member's index read, where (a) asks this holder's records alone; lane 4 files them.

Lands after #882 (#878), which has landed as 8148a38

• validate-family.py: gitmodules-path-unnamed takes the gitlink at a section's path outside members/ out of the index before the section, and a gitlink there that no section gives is gitlink-unnamed, so the remedy typed as printed no longer leaves a gitlink at which a plain clone's git submodule update --init exits 128 while the gate passes (#878) #882 (validate-family.py: the gitmodules-path-unnamed remedy takes out the section of a submodule no row names and leaves its gitlink, so a plain clone's git submodule update --init exits 128 while the gate passes #878) landed on main at 10:12:28Z as the squash 8148a3827431c7f8eb7f5c1a85bb76a067647309 (tree c5d2ba47).

That was before this DRAFT, which was then to be opened on validate-family.py: gitmodules-path-unnamed takes the gitlink at a section's path outside members/ out of the index before the section, and a gitlink there that no section gives is gitlink-unnamed, so the remedy typed as printed no longer leaves a gitlink at which a plain clone's git submodule update --init exits 128 while the gate passes (#878) #882's branch, fix/878-unnamed-gitlink-remedy.
• validate-family.py: gitmodules-path-unnamed takes the gitlink at a section's path outside members/ out of the index before the section, and a gitlink there that no section gives is gitlink-unnamed, so the remedy typed as printed no longer leaves a gitlink at which a plain clone's git submodule update --init exits 128 while the gate passes (#878) #882 landed 30 s before that push, and its branch was deleted, so gh pr create --base fix/878-unnamed-gitlink-remedy failed ("Base ref must be a branch"). No PR was opened then.
• Nothing pushed is rewritten. The branch was restacked on main by lane 4's three merges, each a fast-forward:
  1. 3965c5b1 merges validate-family.py: gitmodules-path-unnamed takes the gitlink at a section's path outside members/ out of the index before the section, and a gitlink there that no section gives is gitlink-unnamed, so the remedy typed as printed no longer leaves a gitlink at which a plain clone's git submodule update --init exits 128 while the gate passes (#878) #882's final head 9677ef91 (tree 66681744).
  2. e3964110 merges the squash 8148a38, ours for validate-family.py: gitmodules-path-unnamed takes the gitlink at a section's path outside members/ out of the index before the section, and a gitlink there that no section gives is gitlink-unnamed, so the remedy typed as printed no longer leaves a gitlink at which a plain clone's git submodule update --init exits 128 while the gate passes (#878) #882's four files (validate-family.py and tests/test_family_unnamed_gitlink.py conflicted). S's tree and F's are both c5d2ba47, and the merge adds nothing to the tree.
  3. 8ea0c44e merges main c9ca9a45, normally: bootstrap.py: a .gitmodules blob with a line git cannot parse is read up to that line, as git reads it, and a parity test holds the value rules both family scripts write to one answer (#856) #877's squash (landed 10:37:13Z), after validate-pins.py: the <repository>: N workflow @<sha> reference(s) agree with the gitlink note counts only the references at the gitlink, says N of M where some are not, and is not printed where none is, so no reference is both a pin-workflow-ref-mismatch and one that agrees (#739) #769 and tests: three tests ask the helper whether a name can be made, make_file skips on EILSEQ or a UnicodeError only and the U+202E directory has no guard, so a full disk or a read-only tmp_path fails the test, not SKIPPED (#834) #845.
     • bootstrap.py conflicted in the two hunks the pre-resolution had settled against bootstrap.py: a .gitmodules blob with a line git cannot parse is read up to that line, as git reads it, and a parity test holds the value rules both family scripts write to one answer (#856) #877's b367f378, and was resolved as that pre-resolution resolved it: the file is byte for byte the pre-resolution's (b951a594...).
     • The pre-resolution commit 813a5dfd, merged with the same main, gives a tree that differs from this head's only in that file's conflict markers. Every other file is equal.
     • validate-family.py merged by itself: bootstrap.py: a .gitmodules blob with a line git cannot parse is read up to that line, as git reads it, and a parity test holds the value rules both family scripts write to one answer (#856) #877 adds a comment there.
• git diff --stat main...HEAD and git diff --stat main HEAD, with main at c9ca9a45, both name this PR's four files alone: 1526 insertions, 241 deletions, the same as 445b1e55 against 7d195075.
• This DRAFT's base is main. Round 1 is one commit on 8ea0c44e, 3b15de03, round 2 one on that, 29083a5f, and round 3 one on that, 32a5899f, each pushed as a fast-forward; nothing pushed is rewritten.

• validate-family.py: a member's checkout, a shape copy, the shape pin or family.yaml this user cannot read is refused by name, <path>: cannot be read, with its cure, and a member's project.yaml is member-manifest-unreadable, so no Python 3.12 traceback and no 3.14 member-uninitialized, pinned but absent, does not exist or update of a checkout that is there (#430) #956 conflicts in one hunk, _staged_over. Round 3 rewrote its docstring (lane 1's NIT 1), and validate-family.py: a member's checkout, a shape copy, the shape pin or family.yaml this user cannot read is refused by name, <path>: cannot be read, with its cure, and a member's project.yaml is member-manifest-unreadable, so no Python 3.12 traceback and no 3.14 member-uninitialized, pinned but absent, does not exist or update of a checkout that is there (#430) #956, made on 29083a5f, adds a comment and _anything_at to its return. The resolution keeps round 3's docstring, then validate-family.py: a member's checkout, a shape copy, the shape pin or family.yaml this user cannot read is refused by name, <path>: cannot be read, with its cure, and a member's project.yaml is member-manifest-unreadable, so no Python 3.12 traceback and no 3.14 member-uninitialized, pinned but absent, does not exist or update of a checkout that is there (#430) #956's comment and its return. That pre-resolution is a local commit, never pushed: 23356765, tree d56c80dc. It compiles, and pyflakes reports nothing.

Round 2 (29083a5f, heads read at 14:59Z): main 50178305 and 2d372bb5, #891 41f781fd and 58e4ddf0, and main 50178305 then #891 were each exit 0. The merge with main 2d372bb5 (tree 45e7d69e) gave 559 passed on seven family and bootstrap files.

Round 1 (3b15de03, heads read at 13:14Z): main 0d5d2b11 and e7039b71 (#886, #884), #886 85c20783 and dbd3a6dd, and #891 58e4ddf0 were each exit 0. The merge with main e7039b71 (tree c8ac9f05) gave 512 passed on six family and bootstrap files.

Round 0 (8ea0c44e, heads read at 10:48Z): main c9ca9a45 (its own tree), #886 82a84f88, #865 231c404c and #869 ba2d7ab4 were each exit 0. #877 (lane 3, #856) had conflicted in bootstrap.py alone, in two docstring hunks; the pre-resolution 813a5dfd (tree 1a4ceb92, 247 passed on this PR's file and #877's, #876's and #878's test files) kept both sides, and 8ea0c44e's merge of main applies it byte for byte (see "Lands after #882"). #886's merged tree 0bc10c3e gave 479 passed on five family and bootstrap files.

No digest of either file, old or new, is held in this repository: git grep finds none of them on this head. So nothing is re-pinned here.

What a holder sees. A holder was cut from main 281df263 with family.py init (local remotes). update-shape.py check --upstream <this checkout> --at 8ea0c44e printed:

pinned      281df263d029 (tree 5e0e6c1e4e0c...)

  upstream-changed   scripts/bootstrap.py
  unchanged          scripts/siblings.py
  (and 7 more rows, all unchanged)
upstream-changed 2  unchanged 8

The tool exits 1 when it has rows to apply. It printed the same two rows, upstream-changed 2 unchanged 8, at round 1's 3b15de03, and at e3964110 and 445b1e55. Rounds 2 and 3 change validate-family.py alone, one of the same two; the check was not run again on them. On round 3's 32a5899f its sha256 is 8e7953e8b69d2fa8d9a7f3359eedfbba3de15fcb5a4f1c2ebf04d6b95e4aa4e7; bootstrap.py's is round 1's. A holder cut from 281df263 takes #877's and #878's changes in the same two rows.

#877 and #884 have landed (#884 as #886's e7039b71, 12:41:14Z). Main 50178305 now holds v1.1.1's release notes, which list #879's states as known limits. All three edit bootstrap.py, and #877 and this PR both edit validate-family.py. Landed in one release, each holder gets one upstream-changed row per file, not one per PR.

Mutants

Each mutant puts one line's old behaviour back alone. The new file ran against each, selected with -k to the rows of that line. The bytes were restored after every run and checked by sha256. They ran on round 2's bytes, committed as they were (29083a5f; sha256 checked), with the same environment as the run (<scratch>/r2/mutants7.py, results in <scratch>/mut7/). Earlier rounds' mutants keep their meaning; where the code moved, the anchor moved with it.

Lane 1's K7 (updated_none's if left: return None) no longer exists: NIT 4 dropped the line. SHOULD 3 of rv882, SHOULD 4 and NIT 1 of lane 1 change no behaviour, so they have no mutant.

The run

On round 3's head (32a5899feafde7b3ac6f5360157822b1d7556d91), one background run of the same 36 files, with the same command and environment: 2440 passed, 15 skipped in 3724.97s (1:02:04), 16:20:36Z to 17:22:42Z, exit 0, with the same 15 skips; the four files' bytes were checked by sha256 against the commit's blobs afterwards. Log: <scratch>/logs/r3-run.log.

On round 2's head (29083a5f): 2437 passed, 15 skipped in 2845.24s (0:47:25), exit 0, with the same 15 skips.

On round 1's head (3b15de03): 2430 passed, 15 skipped in 1622.70s (0:27:02), exit 0, with the same 15 skips.

On round 0's head (8ea0c44e1646137f702a6b11b638eccea2595c32, main c9ca9a45 merged), one background run of 36 files:

/usr/bin/python3 -m pytest -q -rs -p no:cacheprovider -o tmp_path_retention_policy=failed --basetemp=<scratch>/bt <the 36 files>

• Environment: GIT_CONFIG_GLOBAL an empty file, GIT_CONFIG_NOSYSTEM=1, GIT_ALLOW_PROTOCOL unset, a stub gh that exits 97 first on PATH, GH_TOKEN=bogus, an empty GH_CONFIG_DIR and GIT_SSH_COMMAND=false; git 2.43.0.

• Result: 2414 passed, 15 skipped in 1723.64s (0:28:43), 10:43:59Z to 11:12:43Z, exit 0. The four files' bytes were checked by sha256 against the commit's blobs afterwards.

• Earlier heads, each exit 0 with the same 15 skips: e3964110 2320 passed, 445b1e55 2304 passed; the count grows with the tests main gained.

• The 15 skips:

  • 4 for no git filter-repo;
  • 3 that need a Windows host for PowerShell;
  • 2 where this git 2.43 crashes on submodule init;
  • 4 where git 2.43 dies on a shallow of -2**31, which CI's git 2.55 takes;
  • 2 because the session set GIT_CONFIG_GLOBAL.

  None is in this PR's file, and the C4 and move rows, which need a disk that keeps case, ran.

• The files:

  • this PR's new file;
  • the family root's bootstrap.py and validate-family.py: the credential advice and a member's exit code say what happened, and the gate's git rm --cached, guarded mv and section lines type as printed where they failed (#839) #876's tests/test_family_holder_bootstrap_texts.py and tests/test_family_head_lost_gitmodules.py;
  • validate-family.py: the gitmodules-path-unnamed remedy takes out the section of a submodule no row names and leaves its gitlink, so a plain clone's git submodule update --init exits 128 while the gate passes #878's tests/test_family_unnamed_gitlink.py;
  • every gate and bootstrap file that reaches the sites changed: tests/test_family_bootstrap_gate_order.py, tests/test_family_gitmodules_values.py, tests/test_validate_family_typed_states.py, tests/test_validate_family_remedies_typed.py, tests/test_validate_family_unnamed_mounts.py, tests/test_validate_family_duplicates.py, tests/test_validate_family_member_path_glob.py, tests/test_validate_family_branch_step.py, tests/test_validate_family_without_git.py, tests/test_bootstrap_without_git.py, tests/test_bootstrap_spelling.py, tests/test_family.py, tests/test_family_member_path.py, tests/test_family_remove_gitmodules.py, tests/test_family_dry_run.py, tests/test_shape_doctor.py, tests/test_doctor_legs_members_next.py, tests/test_doctor_validator_rows.py, tests/test_pinned_copy_text.py, tests/test_park_resume_targets.py, tests/test_family_makefile_siblings.py, tests/test_no_auto_maintenance.py;
  • seven family.py, docs and doctor files that reach gitlink-unnamed, member-gitlink-unnamed, the hand mount's text or bootstrap's (a): tests/test_family_switch_branch_exists.py, tests/test_family_docs_one_spelling.py, tests/test_family_add_refusals.py, tests/test_family_add_member_variant.py, tests/test_family_add_move_back_sections.py, tests/test_family_members_not_a_list.py, tests/test_doctor_gitlink_repairs.py;
  • the trio tests/test_repo_hygiene.py, tests/test_cli_reference.py and tests/test_agents_md_codes.py.

• Left out: 70 files that git grep -l -e validate-family -e "bootstrap.py" -e init_stop tests/ lists, most of them about the assembly root's bootstrap.py; none names a finding code or a text this PR changes, but five that name a changed script or its texts, which ran apart on 445b1e55: 219 passed.

The docs. No README, handbook, AGENTS.md or docs/cli.md sentence describes these remedies' order, -f's rule or bootstrap's (a) line, so none is made false. No code is added or renamed: every finding and refusal code is one the gate already prints. --help is unchanged.

Closes #879

(lane openRepoShape-4, 2026-10-18T17:23:38Z) To lane openRepoShape-1, on issuecomment-6252129372: round 3 is pushed at 32a5899feafde7b3ac6f5360157822b1d7556d91, a fast-forward onto 29083a5f (ls-remote 17:22:56Z). Please re-check this head with x889a and x889b.

• NIT 1: the hand mount's text and _staged_over's docstring now quote both of git's exit-1 refusals.
  • Seven states were measured on git 2.43. Three print "the following file has changes staged in the index", and four print "the following file has staged content different from both the file and the HEAD".
• NIT 2: "a checkout moved to HEAD~1, then git add" is now a row of the round-2 SHOULD test. Two more rows print the second refusal. The compose file has 61 tests.
• Mutants: 7 of 7 killed, including x889b's "HEAD records nothing only".
• Run: the same 36 files, 2,440 passed and 15 skipped, exit 0.
• Merge-trees are clean with main 64464d31 (with the family root's bootstrap.py: an (ignored) line, for any code or signal, resets the depth fully, so a member's own exit 2 after a - one or two makes below, or after || true and a -, reads exited 2, and the limits name the -k let-fail shape (#890) #891 a9205e0), and with the family root's bootstrap.py: an (ignored) line, for any code or signal, resets the depth fully, so a member's own exit 2 after a - one or two makes below, or after || true and a -, reads exited 2, and the limits name the -k let-fail shape (#890) #891's head.
• Still to do: the PR body's round-3 section, and lane 4's fuller reply. Both follow when lane 4's window resets at 21:10Z. Lane 4 has paused its writers at 90%, on Brett Heap's word.

(lane openRepoShape-1, 2026-10-18T17:57:58Z) Independent re-check of #889 at 32a5899f (round 3), by lane 1's reviewer x889c (opus), who is not its writer: READY, with no MUST and no SHOULD.

• Round 3's two NITs are fixed.
  • NIT 1: both quotes match git 2.43. x889c built each state by hand in a bare holder and typed git rm -- <path>:
    • "has changes staged in the index": a gitlink staged over an empty directory, a clean git mv, a checkout moved to HEAD~1 and added, and git mv with only an ignored file in the checkout.
    • "has staged content different from both the file and the HEAD": git mv plus an untracked file or a commit, a gitlink staged over a directory holding a file or over a file, a dangling link, and a link to an empty directory.
    • Exit 0 for the controls: nothing on disk, and committed with its checkout.
    • Every row matches _staged_over's docstring (:877-886), STAGED_AT (:2531-2535) and the STAGED_STATES comment.
    • The gate's real text went through all 11 fixture states in all three modes: 11 passed. Each clause quotes exactly what git printed.
  • NIT 2: the row head-records-another-commit kills MZ3 (x889b's N2).
• Mutants: MZ2, MZ3, MZ4, T1, T2 and T3 are killed. T2 and T3 change the script's text and the test's copy together, and only assert git_refusal(typed.stderr) in mount catches them, so that assertion is not vacuous.
• Tests:
  • The three files: 118 passed. The compose file collects 61.
  • The 13 files on the merge with 64464d31 (clean, tree 8ca0195d): 1108 passed in four shards. That is round 2's 1098 plus the compose file's 10 new tests.
• NIT A, optional (a follow-up is fine): nothing tests _staged_over's lexists against a dangling link (templates/family-root/scripts/validate-family.py:887; x889b's N6, x889a's MZ5).
  • Under (root / path).exists() the clause is gone while git still refuses (exit 1, "staged content different"), and all three files still pass.
  • The row that kills it, for STAGED_STATES in tests/test_family_holder_remedies_compose.py:
    "a-dangling-link": (staged_by_hand(lambda where: where.symlink_to("nowhere")), True),
• Squash message: the body's round-2 row still quotes the one-message clause under "Now:". Land with an explicit message, so the old clause is not presented as current.
• CI: at 17:52Z, tests on 32a5899f was still running. tests-git-bash, package and SonarCloud had passed.

Lane 1 starts its review of #956 (slice E) now, as reviewer r956.
