* Under pardes's placement a pane whose neighbour is in no column goes at a ↵Gabriel Schneider3 days
| | | | | | | | column's foot, not nowhere After Delcol took the last column's panes, pane/new under Placement made a scratch that no column held, since a scratch was placed only under the asking pane, which was gone; a look from it then unwrapped the missing parent in belowParent and panicked (the 9P monkey's crash-e1873f34). Both now fall back to the foot of the active column, else the last. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Writes held before the shell's clock is first seen no longer overflow its ↵Gabriel Schneider3 days
| | | | | | | | first step A 9P write served before a detached host's first pump holds its batch stamped at time 0, so nextWake said to wake at 20 ms while advance, seeing the clock for the first time, set stepped_ns days later and counted due - stepped_ns back past zero: an integer-overflow panic. It was what the 64 KiB msize trial hit in fs-test (restore detached space, the connection closing at the first write's clunk), a race any msize can lose. A batch's wake is now never before the next frame. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A class with non-ASCII runes matches them: [éa-z] is taken as (é|[a-z]), a ↵Gabriel Schneider3 days
| | | | | | | | range up to 256 runes spelled out mvzr's classes hold bytes, and it refused a multibyte member as a bad expression. Rewriting the class before compiling, as ^a|^b already is, needs no mvzr patch; runes that differ only in their last byte go as one alternative (\xc3[\xa0-\xbf] for [à-ÿ]) so a 256-rune range fits the 512-operation limit, which counts the pattern as rewritten. A wider range and [^é] are refused, naming why. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A write to addr, limit or mark asks for no frame, so its close is not held ↵Gabriel Schneider3 days
| | | | | | | | behind one Every write that changes a pane set needs_frame, an addr write too, so the editor drew a whole frame after each and the clunk that followed waited for the turn while it did: 0.5 ms (Debug) to 1.2 ms a clunk, what made addr and event write-back 4-10x acme's. An address, a limit and the mark flag are nothing drawn; their writes no longer ask for a frame. Clunk after an addr write: 0.518 -> 0.015 ms (Debug tty, fs.py client). Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A pane's ctl reads acme's fields in acme's order, the undo and redo flags ↵Gabriel Schneider3 days
| | | | | | | | included, then pardes's own Where plan9port's line has whether Undo and Redo have a step, pardes's had current, so a client reading acme's fields by position read a word for a flag. The two flags now follow the tab width, as in plan9port's winctlprint, and current|notcurrent and a REPL's id come after them. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A pane's ctl takes acme's ctl words, done by the files that replace themGabriel Schneider3 days
| | | | | | name, put, clean, dirty, del, delete, dot=addr, addr=dot, limit=addr, mark, nomark, show and cleartag were unknown control messages. Each is now done by the file or builtin that replaces it (name, Save, dirty, Del, a Del that does not ask, dot and addr and limit, mark, the tag), checked with the rest of the write before any runs; dump, dumpdir, font, menu and nomenu are refused, EINVAL, saying where pardes does it or that it has no such thing. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* acme's words run as pardes's or are refused, never as shell commands: Put savesGabriel Schneider3 days
| | | | | | Put, Get, Delete, Snarf, Cut, Paste, Zerox, Sort, Putall, Load, ID and Send written to exec or tagexec each ran as a shell command that exited 127, the write answering 0 -- a Put that looked like a save. Put now runs Save and Delete a Del that does not ask; the rest are refused, EINVAL, invalid: acme's X is not a pardes builtin (with where pardes does it, where it does), in exec and ctl alike. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A look that misses file:/re/ names the file and is logged as that file's pane'sGabriel Schneider3 days
| | | | | | A miss said only look: no match for regexp, against the pane the look came from. It now says look: <file>: no match for regexp, on the pane of the file it searched. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A refused Delcol changes nothing: no +Unsaved opens, no focus movesGabriel Schneider3 days
| | | | | | Delcol's refusal opened +Unsaved, placing a pane in the layout it was refusing to change. Its unsaved records and notice say which panes; the list pane is left to the refusals of the other words. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A tag write past the limit is refused whole, naming itGabriel Schneider3 days
| | | | | | A write to tag longer than the room left was cut and applied in part. It now changes nothing and fails ENOSPC, tag: over 4096 bytes; the docs give the limit. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A repeated log record is counted only when its whole text repeats, not just ↵Gabriel Schneider3 days
| | | | | | | | what was cut to fit (xN) compared records after msg and err cut long texts to fit, so two different long failures that agreed in their first 200-odd bytes were counted as one. The whole text of the newest counted record is now hashed, and a repeat needs it too. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Mini with no argument is wrong #args, EINVAL; Find, Grep and Mini say their ↵Gabriel Schneider3 days
| | | | | | | | names capitalised Mini needs a file but did not say so, so a bare Mini ran and failed EIO. It now requires its argument, refused wrong #args (EINVAL) as every such word is. Its failures, Find's and Grep's start with the builtin's own name (Mini:, Find:, Grep:), as the others' do. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A bad command inside an Edit block written whole is named, not the } after itGabriel Schneider3 days
| | | | | | A command in a { block that failed to parse ended the block there, so its } was taken as a control message of its own and the write failed unknown control message "}". A { block not yet closed now runs to its } whatever fails to parse in it, and the error names the command (Edit: unknown command z), as the line-by-line path does. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* pty/run takes one line a run, its answer read before the nextGabriel Schneider3 days
| | | | | | Two lines -- in one write, or as bash writes them, a line at a time on one open -- each ran, and the first's answer was lost under the second's. A write with more than one line, or a next line before the last answer is read, is now refused, EINVAL. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* pty/ctl exec on a command pane is refused: a command pane does not restartGabriel Schneider3 days
| | | | | | exec on a finished command pane ran its line again, silently, with no header, footer or records. It is now refused, EINVAL, invalid exec: a command pane does not restart. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A failure said while a 9P write waits on it posts no msg, only the write's errGabriel Schneider3 days
| | | | | | A failure the editor said as it performed a write's work (a Save's disk write, a shell, a language server) was posted as a msg and taken back out when the write's err was logged, which it cannot be once a log follower has read it: a follower saw both. Such a failure is now posted without a msg in the first place (fs.write_waits), and nothing is taken back. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* An open's writes in a row to one place go in as one edit: a 10 MB body write ↵Gabriel Schneider3 days
| | | | | | | | is linear Each body or data write copied and hashed the whole buffer, so a write the mount cut in 8 KB pieces was quadratic: 10 MB took 50 s and a 1 MB insert into 10 MB 11 s, holding the editor's turn. An open's appends to body, or inserts going on at data's address, are now held and put in as one splice (one copy, one undo step, one line-starts pass) before any other request, the close, or the editor's step once the writes pause 20 ms. fs.py-driven: 2 MB 2.19 -> 0.16 s, 10 MB 50.17 -> 0.78 s, 1 MB data into 10 MB 11.49 -> 0.26 s. A body-2m case (2 MB in 256 KB writes on one open) joins the perf gate: 84023 -> 15785 us; baselines re-recorded. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* An Edit x gives each of its searches the step budget, and a search that ↵Gabriel Schneider3 days
| | | | | | | | spends it says it took too much time The budget was the compiled pattern's, spent over every search an x made: Edit ,x/x+/c/z/ over 100k lines ran out and failed, blamed on backtracking. Each search now starts with the whole budget, and one that spends it says regular expression search took too much time, gave up. (Not "too long": 9ns reads those words as ENAMETOOLONG.) Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A pattern up to 512 characters compiles; a longer one is refused naming the ↵Gabriel Schneider3 days
| | | | | | | | limit mvzr's Regex holds 64 operations, so a pattern much past 64 bytes was refused as bad regular expression. pardes now compiles into mvzr's SizedRegex(512, 64), and a pattern that is too long (told apart from a malformed one by compiling it with room) says it is longer than mvzr's 512 operations. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A ctl or exec line with no newline runs with its write and fails it, unless ↵Gabriel Schneider3 days
| | | | | | | | it needs more A last line with no newline was held to the close, so printf bogus > ctl answered 0 and failed only in the log, Edit ,s/zzz/y/ too. A write shorter than its Twrite is the whole of what was written (acme takes each write whole): its tail runs then and a failure is the write's. It is held only when the parser says it needs more -- an open { block, an a/c/i text -- or when the write filled its Twrite and may go on (the listener tells the core the room, msize less its header). Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Every catch unreachable, orelse unreachable and syscall assert outside tests ↵Gabriel Schneider3 days
| | | | | | | | is a real refusal or says why it cannot fire A sweep for round 23's crash: a run's answer (pty/run) was bufPrint'd into 48 bytes with catch unreachable, so a foreground program's long name (macOS gives up to 32 bytes) panicked; it now cuts at the room, keeping its newline, in 96 bytes. The rest were numbers into buffers sized for them, a braille codepoint, pthread calls on the queue's own mutex, and pdf_view's resolved outline entries: each now carries a one-line comment saying why it cannot fire. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Delcol on the last column leaves the window, empty but for its workspace ↵Gabriel Schneider3 days
| | | | | | | | tag, as acme's does The last column's Delcol ended the session. The window now stays, with only the workspace tag; Newcol, and New (which makes the column it goes in), start it again. A word run with no pane at all runs with a stand-in that is no pane, the root ctl takes session words, and pane/new makes its scratch in the session's directory. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A name refused for a leading blank says a blank at its startGabriel Schneider3 days
| | | | | | Both ends said a blank at its end. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Not-found failures say it once, in plain words: grep: pattern not found, ↵Gabriel Schneider3 days
| | | | | | | | callers not found The ENOENT that 9ns reads from a failure's words came from a tacked-on suffix, grep: no match, not found, definition: nothing found, not found, no shell "x", not found. They now say it once: grep: pattern not found, find: name not found, Callers: callers not found, definition: not found, shell "x" not found (...). Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A Recent or Jumplist row for a file that shrank lands on its last line, the ↵Gabriel Schneider3 days
| | | | | | | | same by either route, and says so A +Recent row clamped silently and a Jumplist row missed (has no line N). Both are remembered places now: the look clamps to the file as it is, closed or open, and the message row says <file> has N lines now: at its last. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A new file, once saved, shows in /recent, openGabriel Schneider3 days
| | | | | | A pane named for a file not yet on disk is not kept in Recent (round 22), and its Save did not add it, so the file stayed out of /recent while open. A Save that puts a file on disk now records it. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A PDF that cannot be read fails its look with its path and whyGabriel Schneider3 days
| | | | | | A truncated PDF said only look: <error>, with no path, where an image that cannot be read names both. It now says look: <path>: not a PDF pardes can read: <why>. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A second line written to name is refused EINVAL, in one write or on the same ↵Gabriel Schneider3 days
| | | | | | | | open bash writes printf 'a\nb\n' a line at a time, so each line arrived as a whole name on the held open and renamed the pane twice. An open that has named its pane now refuses a further line, as a two-line write already was. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A buffer whose file was deleted on disk is dirty, and Del asks firstGabriel Schneider3 days
| | | | | | A file deleted under an open buffer left dirty 0 and let Del, Exit and the rest throw the only copy of its text away unasked. It now counts as dirty, as acme's does, and the refusals ask about it. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A listing freezes at its open, so a read in several chunks never splices two ↵Gabriel Schneider3 days
| | | | | | | | moments /index and the other listings were rendered afresh for each read, so a client reading one in chunks while panes changed got rows from two moments spliced together (the fs-test flake). /index, /layout, /recent, /commands, /status, /listeners and a ctl opened only to read now freeze at the open, as /screen does. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A Jumplist entry is (closed) only while no pane has its file openGabriel Schneider3 days
| | | | | | A closed file's entries stayed closed after the file was opened again another way (a look, Recent), so Jumplist said (closed) of an open file and a step onto it reopened it. They are now that pane's as soon as a pane shows the file. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* +Unsaved drops a pane once it has closedGabriel Schneider3 days
| | | | | | The list kept a pane's Modified row after the pane was closed (discarded), so it named text there was no longer anything to lose of. A pane's closing now takes its row out. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* After a failed address, one that goes from it (., +, -) says there is noneGabriel Schneider3 days
| | | | | | addr kept the old address under a failed one, and an address written relative to it went from that old one. Such an address now fails with no address: the last one written to addr failed, until one that stands alone is written. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Symbols, Diagnostics and every language server list share their directory's ↵Gabriel Schneider3 days
| | | | | | | | one +Search Only Find and Grep reused the directory's +Search; a language server's list made another pane of the same name each time. Every origin named +Search now shares it, but a plain word's search, which keeps a list a pattern for n/N to walk between. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A pattern with a newline and an anchor mvzr would misread is refused EINVAL, ↵Gabriel Schneider3 days
| | | | | | | | as the doc says Its words named no malformed input, so 9ns read the refusal as EIO, and Edit's failed EIO directly. It now says bad regular expression: ..., and Edit's failure with those words is EINVAL too. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* addr takes a row's range, L:C-L2:C2 or L:C-C2, so a Recent, +Search or ↵Gabriel Schneider3 days
| | | | | | | | Jumplist row pastes in The rows spell a range L:C-L2:C2 (inclusive), which addr read as L:C then back L2 lines. After an L:C, a - and a number is now that range, through its last character; the docs set both spellings side by side. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A look at a corrupt image fails with an err rather than open a blank paneGabriel Schneider3 days
| | | | | | An image stb_image could not read opened as an empty image pane, the look succeeding. The bytes' header is now checked at the look (stbi_info_from_memory), and one that is no image it reads fails the look, look: <path>: not an image pardes can read, making no pane. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A PDF's body reads the text layer of the page it showsGabriel Schneider3 days
| | | | | | The body of a PDF pane read as empty. It now reads MuPDF's text extraction of the page shown, the text search and n/N already use, read-only (a write is refused, as round 22's body refusal made it). Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Two opens writing one body are separate undo steps, however they interleaveGabriel Schneider3 days
| | | | | | The join mark a write left was the pane's, so another open's write joined the first open's step. Writing opens of body, data and xdata now get an open record, the mark names the open that set it, and another open's write starts its own step (the pane's one history: each turn the opens take is a step). Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Back or Forward over a closed file deleted since skips it and goes on, saying soGabriel Schneider3 days
| | | | | | A jumplist entry for a closed file no longer on disk tried to reopen it, failed as a look, and left the step stuck there. Its entries now go, the message row says <path>: deleted, skipped, and the same step is taken over what is left. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A name cut across writes on one open is one name, applied onceGabriel Schneider3 days
| | | | | | Each write to name was taken as a whole name, so a name a client wrote in two pieces renamed the pane twice, the first time to half a name. name's writes are now held per open, as exec's and ctl's lines are, until the newline or the close. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A clamped Recent range ends at a line's last character, never swallowing its ↵Gabriel Schneider3 days
| | | | | | | | newline A range past the end of a file that had shrunk was clamped to the empty line after its final newline and to one past a line's last character, so the selection took the newline in. Its ends now clamp to the last line and to its last character, as addr's L:C does. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A look miss said again is its err record counted, as any repeated err isGabriel Schneider3 days
| | | | | | Look's miss pushed its err record plain, so a script retrying one look filled the log with the same line, where other errs are counted (x2). Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A language server question that finds nothing, cannot be answered or has no ↵Gabriel Schneider3 days
| | | | | | | | room fails, and so does a write to an image's or PDF's body Callers or Callees with nothing found, Hover or Lspwhy with no room for its pane, and a question asked of no file's pane said nothing, the 9P write succeeding; a body write to an image or PDF pane went nowhere. A write that asks a language server now waits for its answer (turn.lsp_answers), and what fails there -- nothing found, no answer, a backend's @none why, a placement with no room (ENOSPC) -- fails the write and logs its err. No diagnostics is said, not failed. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A builtin or setting this build lacks is refused GUI-only, from an exec tooGabriel Schneider3 days
| | | | | | On a terminal, Fonts written to an exec was no builtin there, so it ran as a shell command and ended exit 127; ctl said unknown control message. Both now say Fonts is GUI-only, invalid here (a builtin another platform's build has, not in this build). Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Theme takes a name in any case, and a miss names its nearest themesGabriel Schneider3 days
| | | | | | Names were case-sensitive, and a miss listed only the first letter's themes that fitted 40 bytes, 4 of the many d ones. It now lists every theme sharing the first letter when they fit the 128 bytes an Rerror carries, else the nearest by a plain likeness score (shared prefix, the name inside, its letters in order). Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A Dump into a DumpDir that is no directory says so; the doc says a missing ↵Gabriel Schneider3 days
| | | | | | | | last directory is made DumpDir /dev/null said no such directory though it is there, and the doc claimed a missing DumpDir always fails, where its last component is made at the Dump. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Recent keeps only files on disk, and its cap never drops an open oneGabriel Schneider3 days
| | | | | | A renamed scratch never saved and a /virtual/ pane were recorded as recent files, and at 200 the oldest entry went even when that file was open. Opens, renames and closes now record a path only when it is a file on this host, and the cap drops the oldest closed entry. A name with a newline is not written to the kept list, where it would read back as two. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* get's refusal over unsaved text logs its unsaved record, as the other ↵Gabriel Schneider3 days
| | | | | | | | refusals do Exit, Restore, Del and Delcol log unsaved <serial> <name> before their err; get logged only the err. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* The panes present at boot are the log's first records, before what an init ↵Gabriel Schneider3 days
| | | | | | | | file said The boot announce ran after the init file, so its msg (ThemeSel: renamed to Themes) came before new 1. A msg or path record said while the log is still empty now announces the panes first. Co-Authored-By: Claude Opus 5.5 <[email protected]>
