* refactor(vfile): give the checkout's vfile encoding one owner (#233) Checkin, stash and status each decoded fossil's vfile columns on their own: rid=0 for an add, origname==pathname on unrenamed rows, chnged merge codes. That is how #228 happened, and stash still had it wrong: it selected chnged=1 only, so files changed by a merge (chnged 2..9) were silently left out, and it stashed a rename as a plain edit. New package internal/vfile owns the encoding. Load reads a version's rows; Row answers what callers ask (IsAdded, IsRemoved, RenamedFrom, ContentChanged, PendingMerge); Classify gives the change type in fossil's order. checkout.FileChange is now an alias of vfile.Change, so the checkout API is unchanged. internal/checkout's status, Extract safety check and checkin read rows through it. The never-read vfileCommitEntry.changed field is gone. internal/stash selects changes with vfile.Classify against the checked- out version and refuses a pending merge or rename by name, since its save and revert paths restore files by current name against the committed version and would drop either. Its store-and-revert loop is split into stashRecord and revertStashedFile; removed and modified files share one revert path, keyed by row id. * fix(vfile): a pending merge is chnged 2-5 or mrid != rid (#233) PendingMerge counted every chnged above 1 as a merge, but 6 through 9 record a change to the executable or symlink bit; fossil leaves chnged=6 after a plain chmod +x. Stash then refused an ordinary permission change as "a pending merge". It also ignored mrid: an edit made on top of a merge drops chnged back to 1 while mrid still names the merged-in content, so the refusal could be bypassed and the merge half-dropped. Row now carries mrid; PendingMerge is chnged 2..5 or mrid != rid, and ModeChanged covers 6..9. Stash refuses a permission change with that reason, since its revert writes default permissions. Load reads a NULL rid as 0 and a NULL mrid as rid, the tolerance the checkin code had when it scanned rid into a NullInt64. * refactor(checkout): ask vfile.Row about merges in Extract's check (#233) Extract's safety check relaxed only rows with chnged == 1, decoding the column itself. It now asks the row (not a pending merge, not a mode change), keeping fossil's encoding in internal/vfile. Equivalent for every real row. nextChangedState's comment no longer calls the mode changes (6..9) merge states. |

fix(cli): add, rm, rename and revert call the library (#234) (#245)
* fix(cli): add, rm, rename and revert call the library (#234) These commands wrote the checkout's vfile with raw SQL, each with its own copy of rules the library already gets right, and ignored most Exec errors. rename recorded the new name but left the file under the old one, so the next commit failed on a "missing" tracked file. revert only cleared change flags over an edited file and restored nothing. add wrote a SHA1 mhash whatever the repo's hash policy. They now open the checkout through the library (openWorkingCheckout, which finds the repository from the checkout when -R is not given) and call Add, Remove, Rename and Revert, returning every error, including from closing. rename moves the file, like fossil mv --hard; revert restores committed content, like fossil revert. Two library gaps the CLI exposed are fixed where they live, matching fossil's revert: - Revert refreshes change flags from disk before choosing files, so an edit no scan has recorded yet is reverted instead of skipped. - Reverting a never-committed add un-manages it and leaves the file on disk. It used to delete the file, destroying the only copy; fossil prints UNMANAGE and keeps it. revertFile's restore path moves to restoreCommitted, bringing it under 70 lines. The merge, merge-resolve and conflicts commands are #244. * docs(changelog): note the CLI and Revert changes (#234) * fix(checkout,cli): revert and rename match fossil; find repo without -R (#234) Review of the CLI switch found the library and the new helper falling short of fossil: - Without -R, every command failed on a fresh fossil checkout: the repository lookup opened the checkout database read-only, which clashes with the WAL pragma on a database fossil left in delete journal mode, and hid the real error. It now opens it as the library does, reports the error, and resolves a relative repository path, as fossil open stores it, against the checkout's directory. - Rename moved the file onto an existing untracked file, destroying it. It now refuses, as fossil mv --hard does, before changing anything. - Revert skipped a file missing from disk (no change flag records it) while the CLI reported it reverted. A named file is now reverted whatever its flags say, and revert-all includes missing files. - Revert left merge state behind: restored rows kept mrid on the merged-in version and vmerge kept its row, so the next scan saw the file changed and the next commit recorded a merge parent. Restored rows now reset mrid and mhash, and revert-all clears vmerge, as fossil's revert does. Rename's vfile lookups move to renameRowID and revert-all's selection to needsRevert, keeping both functions under 70 lines. The re-add test now checks the vfile row itself, since fossil's own scan would hide a stray chnged=1. * fix(checkout): revert removes a file a merge added, as fossil does (#234) Revert decided between restore and un-manage by rid alone. A file a merge added has a non-zero rid (its merged-in artifact) but is not in the checked-out version, so revert restored it as if committed and left it tracked; the next commit then included it. Fossil looks the file up in the version's manifest and, when it is absent and rid is not 0, deletes the file and its row (its content lives on in the merged-in version). revertFile now takes the vfile row and the version's path set and does the same: a pending add is un-managed and kept on disk; a file the version lacks, under its name or its name before a pending rename, is removed; anything else gets its committed content back. Checking the pre-rename name keeps a renamed, edited file from being deleted. Rename's refusal message now fits a directory at the destination too. * fix(checkout): never remove a non-file when reverting a merge add (#234) removeMergeAdded deletes only a regular file at the merge-added path; anything else there, such as a directory the user made, is left alone. Revert's doc now says edits to reverted files are discarded: fossil saves an undo copy first, go-libfossil has no undo yet. check-in: de8f3ed302 user: [email protected] tags: trunk | |

* refactor(vfile): give the checkout's vfile encoding one owner (#233) Checkin, stash and status each decoded fossil's vfile columns on their own: rid=0 for an add, origname==pathname on unrenamed rows, chnged merge codes.

fix(checkout): classify changes in one place; report missing files (#232) (#241)
* fix(checkout): classify changes in one place; report missing files (#232) HasChanges, VisitChanges and Extract's safety check each decided what counts as a change: two SQL WHERE clauses and classifyChange, with an error path whose only job was catching their disagreement. They had already drifted once (HasChanges missed renames until #229). Now one reader, loadVFileRows, returns every row of a version and one classifier, classifyChange, judges it, in the order fossil's changes command uses: removed > missing > added > renamed > modified. A renamed file that is also edited stays "renamed", so callers that see only the change type do not lose the rename. The WHERE clauses and the malformed-row error are gone. VisitChanges with a scan now reports a tracked file that is gone from disk as ChangeMissing, which the public API already exposed as "missing" but nothing produced; such files were left out, or shown as added or modified. HasChanges sees a fossil add (rid=0, chnged=0) without a scan, since rid=0 now always means added (#231). * fix(checkout): treat a non-file at a tracked path as missing (#232) ScanChanges read each tracked path and failed the whole scan when a directory stood where a file belongs. Fossil's scan reports that path as NOT_A_FILE under its missing filter. The scan now stats first and treats anything that is not a regular file as missing, so Status reports it instead of erroring. loadVFileRows orders rows by pathname, as fossil's changes lists them. The changelog notes that checkouts written before #231 may hold rid=0 placeholder rows, which HasChanges now counts. check-in: ff9c1af49d user: [email protected] tags: trunk | |
