sneak 5cee2b28d0 check always warns about files the manifest does not list (closes #103)
check / check (push) Failing after 2s
Details 
check now always looks under the base directory for files the manifest
does not list, hidden files and directories included, and prints one
warning per file. The result still depends only on the listed files;
--no-extra-files turns each unlisted file into a failure, and --quiet
hides the warnings but not the failures. A directory that cannot be
listed is reported the same way, and the search goes on past it.

The manifest itself is left out by file identity, as gen and freshen
do; a symlink under the base is compared by what it points to. A base
directory named through a symlink is resolved before the search.

clawbot 400a2f8f63 Move FORMAT.md to docs/ and contrib/ to bin/, fix bash script style (closes #74)
check / check (push) Failing after 3s
Details 
FORMAT.md moves to docs/ and every reference follows; its two relative
links to mfer/mf.proto now point up one directory, its text is otherwise
unchanged. contrib/usage.sh moves to bin/, not docs/: it is a script you
run (it builds mfer, then generates and checks a manifest of the repo),
not reading material. Both scripts now use #!/usr/bin/env bash,
set -euo pipefail and a main function. bin/gitrev.sh still exits non-zero
outside a git checkout, so the Makefile still falls back to unknown.
.gitignore now ignores only the built bin/mfer rather than all of bin/,
which holds tracked scripts.

clawbot ba3d24ca42 End-to-end tests for freshen and fetch (closes #66)
check / check (push) Failing after 3s
Details 
The freshen tests built a fixture and never ran freshen. They now run
gen and freshen through the command entry point on a temp dir: an
unchanged tree leaves the manifest's entries as they were, and a
modified file (also one edited without changing its size), a new or a
deleted file gives a manifest that lists exactly the tree, with sizes,
hashes and mtimes from disk, on which check passes.

New fetch tests run the command against an httptest server: a nested
tree lands complete, a hash mismatch exits non-zero and leaves no file,
and a partly filled destination gets every listed file downloaded again
and replaced, while a file the manifest does not list is left alone.

clawbot 11041330a7 Move internal/log from apex/log to log/slog (closes #77)
check / check (push) Failing after 2s
Details 
internal/log now logs through log/slog. After Init, records go to a small
slog.Handler that prints the same lines as before; before Init they go to
slog.Default(). The helpers and their call sites are unchanged. With
NO_COLOR set on a terminal, log lines are no longer colored.

pterm is dropped: it only printed progress lines, which fmt now writes
directly, outside slog. apex/log, pterm and their indirect dependencies
leave go.mod; golang.org/x/term becomes direct.

simplelog is not imported: importing it replaces slog's default handler in
every program that imports package mfer. The logger stays process-global,
since injecting it would change package mfer's API.

Progress and log lines now share the logger's lock, so the check progress
test runs check ten times to catch a missing wait.

clawbot 5c7ef94799 Set go_package to the sneak.berlin/go/mfer module path (closes #79)
check / check (push) Failing after 1s
Details 
mf.proto named git.eeqj.de/sneak/mfer/mfer as its Go package, which
disagrees with the sneak.berlin/go/mfer module path go.mod declares.
go_package is now sneak.berlin/go/mfer/mfer, the import path of the
mfer/ package. mf.pb.go is regenerated with make generate, which
changes only the go_package bytes in its embedded descriptor, and
mf.proto.sha256 records the new mf.proto hash.

clawbot 82b9434444 fetch: client timeout, retry with backoff, url.JoinPath (closes #63)
check / check (push) Failing after 2s
Details 
fetch now makes every request through an http.Client with a time
limit, ten minutes by default and set with --timeout, which must be
greater than zero. A connection error, a timeout, or a 5xx or 429
response is retried, up to five tries in all, after a random wait
whose limit doubles from one second, or after the wait the server's
Retry-After asks for, up to one minute. Each try of a file starts a
new temp file, so a retry never keeps a partial file; the size and
hash checks are unchanged. Manifest and file URLs are built with
URL.JoinPath, so trailing slashes, query strings and names that need
escaping all work.

clawbot 6a2307a82b check waits for its progress output before the summary (closes #140)
check / check (push) Failing after 1s
Details 
With --progress, runCheck started the progress goroutine but waited
only for the results goroutine, so check could log its summary, or
return, before the last progress line was written and cleared. The
progress goroutine now signals a sync.WaitGroup when it finishes, and
runCheck waits on it as soon as Check returns, as generate does.

The new test sends stdout and stderr to one buffer and slows down
stdout writes, so without the wait the progress output lands after
the summary.

clawbot 4bf87d1ccf AddFileWithHash rejects hashes that are not multihashes (closes #129)
check / check (push) Failing after 2s
Details 
AddFileWithHash took any non-empty bytes as a hash, so the builder could
write a manifest that mfer refuses to load. It now decodes the hash with
go-multihash and also requires a digest of at least 32 bytes, the SHA-256
length the reader's decoding-cost limit assumes: a valid but shorter
multihash, such as an empty identity hash or SHA-1, still makes a
manifest of one-character paths too costly to load. When mfer freshen
meets such a hash in an existing manifest, its error names the manifest
entry and says to regenerate the manifest with mfer generate. Test
fixtures whose stand-in hashes were not valid multihashes now use a
SHA-256 multihash.

clawbot e412d20c20 Default the manifest to index.mf and keep it out of its own listing (closes #100)
check / check (push) Failing after 1s
Details 
mfer gen now writes index.mf instead of .index.mf, the name fetch
requests and the README calls the standard filename. Given a
directory, check, freshen, list and export look only for index.mf;
.index.mf is no longer recognized. Because index.mf is not hidden, gen
and freshen leave out of their own listing the manifest they write and
a temp file an interrupted run left beside it, matched by file
identity (os.SameFile) however the path is spelled. The scanner takes
these as a plain ExcludePaths list; manifestTempPath alone names the
temp file, for both writes, both skips and the tests.

clawbot 0501568203 Never regenerate mf.pb.go during checks; fail when it is stale (closes #71)
check / check (push) Failing after 1s
Details 
The test and format scripts regenerated mfer/mf.pb.go whenever
mfer/mf.proto looked newer by mtime, which a fresh checkout often causes,
so make check could rewrite a committed file and needed protoc. Nothing
regenerates it any more except make generate (script/generate), which
refuses to run unless protoc 33.4 and protoc-gen-go v1.36.11, the
versions that wrote the committed file, are on PATH, and records the
hash of mf.proto in mfer/mf.proto.sha256. A Go test compares that hash
with mf.proto and fails, naming make generate, when they differ. The
mtime rule, the unused protoc-gen-go v1.28.1 install rule, make clean's
deletion of mf.pb.go and the Dockerfile's touch workarounds are removed.

clawbot 0a9963002c NewChecker takes CheckerOptions instead of positional arguments (closes #78)
check / check (push) Failing after 1s
Details 
NewChecker now takes *CheckerOptions (ManifestPath, BasePath, Fs), named
like ScannerOptions. A nil Fs still means the OS filesystem, as before and
as in ScannerOptions; nil options or an empty path return an error naming
the missing path.

Audit of the other exported constructors in mfer: NewManifestFromFile took
a filesystem and a path positionally; it now takes
*ManifestFromFileOptions (Path, Fs) with the same nil and empty rules.
NewBuilder and NewScanner take no arguments, NewScannerWithOptions already
takes options, and NewManifestFromReader takes one reader, which the style
guide exempts; these are unchanged.

clawbot 76116005c8 Reject manifests whose file entries decode far larger than their bytes (closes #123)
check / check (push) Failing after 2s
Details 
Before decoding the manifest, the parser adds up what decoding sets
aside for each file entry, hash, timestamp and MIME type, however short
its encoding, and refuses the manifest once that passes 8 times the
decompressed size; manifests mfer writes come to at most about 7.15
times. Empty entries decoded to about 50 times their size: under 1 KB of
manifest allocated about 500 MB. Fields the decoder does not know are
dropped; kept, they took up to 5 times more. A test refuses entries
counted just over 8 times and loads them just under. The fuzz ceiling
rises from 16 to 20 times the input and decompressed data; seeds of
empty entries and of empty hashes fail it without the fix.

clawbot 7088857692 Count -v once and document -v -v for debug output (closes #125)
check / check (push) Failing after 2s
Details 
urfave/cli before v2.25.5 counted a flag given by its alias twice, so
one -v or --verbose already gave debug output. Bump it to v2.27.7,
which counts it once: one -v gives verbose output, two give debug.

The -v help text now says -v -v instead of -vv, which stays refused:
urfave/cli's option for combined short flags would let a flag that
takes a value read the next letter as its value.

-v and --verbose together stay refused: urfave/cli v2 refuses a flag
given under two of its names, and one flag with an alias keeps help and
parsing simple.

The bump changes some help output; generate and fetch now name their
arguments. Tests start each run at the default log level.
