f578bede0c ci: add a no-python3 job reproducing the Debian buildd chroot
GitHub runners ship python3, so every make-check job exercised the
python3-present path and the local-server tests never skipped. The Debian
buildds build in a minimal chroot with no python3, where those tests must
SKIP (exit 77) -- and 28_local-pause failed there instead, FTBFS on every
arch for 3.49.10-1, invisible to CI.

Add a job that builds, removes python3, and runs make check, so the skip
path is exercised on every PR. Verified to fail on the pre-fix tree and pass
after.

45279d7357 tests: skip 28_local-pause when python3 is absent (Debian buildd)
The local-server tests all skip with exit 77 when python3 is missing, but
28_local-pause runs local-crawl.sh inside a command-substitution with output
redirected to /dev/null, swallowing that exit-77 skip signal. On a host with
no python3 (every Debian buildd) both crawls then run serverless, finish in
0s, and the test reports FAIL instead of SKIP, turning 3.49.10-1 red on all
architectures. Add the same python3 guard the other tests get via
local-crawl.sh, up front, so it skips cleanly.

cca83e5f4a Modernize HTML entity decoding to the WHATWG named character references (#444)
* Modernize HTML entity decoding to the WHATWG named character references

Regenerate htsentities.h from the WHATWG entities.json (2032 single-codepoint
names) instead of the 1998 HTML 4.0 set (252 names). The dispatch hash moves
from a 32-bit LCG to 64-bit FNV-1a; the generator now aborts on any (hash,len)
collision, so the hash-only switch stays correct without a runtime name compare.
Bump the consumer name-length cap from 10 to 31, the longest name
(CounterClockwiseContourIntegral), or long names would be rejected outright.
Multi-codepoint references (~93 obscure math entities) can't fit the
single-codepoint return and are skipped, left verbatim as before.

Also fix the dead ftp://ftp.unicode.org URLs in htsbasiccharsets.sh.

Closes #443

* entities: harden the generator collision guard and widen test coverage

Review follow-up. The switch keys on the hash alone, so check hash-alone
uniqueness among emitted names (a same-hash/different-len pair would otherwise
slip the old (hash,len) check and surface only as a cryptic duplicate-case
compile error). Also hash the ~93 skipped multi-codepoint names and abort if any
aliases an emitted hash, so "skipped means verbatim" is enforced rather than
assumed on future regens.

Add a runtime sweep of common HTML4 names (copy/reg/trade/mdash/ndash/alpha/beta)
to 01_engine-entities.test: a regression guard against accidental drops and a
generator-vs-consumer hash cross-check on names beyond the handful already
probed.

97f398e508 Release 3.49.10 (#442)
Bump the package version to 3.49.10 and curate the release notes.

VERSION_INFO goes 3:1:0 -> 3:2:0: the cycle only appended tail fields to the
installed options struct (--cookies-file, --pause, --strip-query, the -%u
split), no existing symbol or offset changed, so the soname stays .so.3.

history.txt gets the 3.49-10 block; debian/changelog gets 3.49.10-1 with the
Debian-specific items (DEP-5 copyright, chromium-first browser dep, minizip
embedded-library override). Standards-Version 4.7.0 -> 4.7.4: the intervening
Policy changes (usr-merge, /usr/games, Priority recommendation, -dev linker
scripts, non-free-firmware) need no package change.

a62f93a107 Strip the #fragment from a redirect Location before fetching (#204) (#441)
* Strip the #fragment from a redirect Location before fetching (#204)

A 302/30x Location is dereferenced, not displayed, so its #fragment is a
client-side anchor that must be dropped before the target is requested.
httrack kept it: the redirect followers copied r.location verbatim, so the
re-request carried `GET /page.html#frag` (strict servers answer 400) and the
mirror was saved under a fragment-polluted name. HTML links were already
stripped at parse time; only the two Location followers were not.

Drop the fragment in a small helper called at both follow sites, covering
the live and cached-redirect paths.

* test(#204): strict-server guard so a leaked fragment is a wire-level failure

The first cut of 29_local-redirect-fragment only checked the saved filename.
Python's urlsplit() drops the fragment before routing, so a `#` leaked into
the GET line still routed to the target and the crawl passed: the assertion
was a proxy, not the wire behavior the fix targets. Make the server strict
(400 on any `#` in the request-target, like the real servers in #204), so a
leaked fragment now logs an error and the target is never saved. Neutering the
fix makes the test fail with the exact "400 Bad Request" from the issue.

799ec88dc7 filters: fix escaped brackets inside *[...] character classes (#440)
* filters: decode escaped chars correctly inside *[...] classes

The escape branch in strjoker probed joker[i+2] instead of the current
char, so a backslash escape only worked as the first class member:
'*[\[\]]' (documented as "the [ or ] character") matched only ']', and
'*[a,\[]' dropped the 'a'. The loop also treated any ']' as the class
terminator, so an escaped ']' could never be a member.

Decode the escape first in the loop body: a backslash takes the next char
as the literal member (only that char, not also the backslash the old code
added), and an escaped ']' is consumed before the terminator check. So
'*[\[\]]' now matches both brackets, and escape precedes the range/size
checks ('\-' '\,' '\<' become literal members). The self-test previously
pinned the buggy output as expected; it now asserts the documented
behavior and fails against the old matcher.

Closes #148

* filters: fix a 1-byte over-read on a truncated range *[a-

The *[...] class parser's range arm does i += 3 unconditionally, so a
pattern ending in a dangling '-' (e.g. *[a-) read one byte past the NUL:
joker[i+2] is the NUL, i jumps to len+1, and the separator skip and loop
guard then read joker[len+1]. Guard the range arm on joker[i+2] != '\0'
so a truncated range falls through to the literal-member path instead of
overshooting.

The filter self-test now copies the pattern and string into exact-size
heap buffers so a sanitizer traps such over-reads; the pattern previously
came straight from argv (no redzone), which is why this stayed invisible.
A *[a- test case exercises it.

71af4a24f0 lang: add a translation guide and fix the English colon spacing (#439)
Document the lang/*.txt format and contribution flow in lang/README.md
(linked from CONTRIBUTING.md); the project had no written instructions for
translators. Also drop the stray space before the colon in the English
"Filters (refuse/accept links):" label so it matches the other labels. Only
the English.txt value is changed, not the msgid key, so existing
translations still resolve.

e17f4f12a0 Add --pause to space out file downloads by a random delay (#185) (#438)
A new --pause MIN[:MAX] (seconds, -%G) waits a random MIN..MAX between
files so a crawl looks less like a bot and is gentler on the server; a
single value is a fixed delay. Disabled by default.

It reuses the existing non-blocking launch gate
(back_pluggable_sockets_strict): rather than Sleep() -- which would freeze
the single select() pump and stall the other in-flight transfers -- the
gate just withholds new launches until the delay elapses, one file per
gap. The per-gap target is derived from the last-request timestamp so it
stays stable across the many gate evaluations within a gap yet rerolls on
each launch; sampling rand() per evaluation would instead bias the
realized delay toward MIN.

Two int fields appended at the httrackp tail (ABI-stable, no soname bump).
Covered by a pure-function self-test (range + spread, with teeth against
the min-bias bug) and a local-server crawl that asserts the pause slows a
multi-file mirror.

Closes #185

# Translating HTTrack
Interface strings live here, one `.txt` file per language. `English.txt` is the reference: every other file maps each English string to its translation.
## File format
Plain text, entries in consecutive pairs of lines:
```
<English string>
<translation>
```
The first line of a pair is the lookup key and must stay identical to the one in `English.txt`; translate only the second line. Missing entries fall back to the English text at runtime, so a partial translation works.
Preserve any `\r\n`, `\t` and `printf` placeholders (`%s`, `%d`, ...) in the translation.
A few `LANGUAGE_*` entries at the top describe the file itself:
| Key | Meaning |
| --- | --- |
| `LANGUAGE_NAME` | Name shown in the language picker, in its own language (`Deutsch`, not `German`) |
| `LANGUAGE_ISO` | ISO 639 code, with region if needed (`de`, `pt_BR`) |
| `LANGUAGE_CHARSET` | Encoding the file is saved in (`ISO-8859-1`, `windows-1251`, `UTF-8`, ...) |
| `LANGUAGE_AUTHOR` | Your name and contact |
| `LANGUAGE_WINDOWSID` | Windows locale name used by WinHTTrack (`German (Standard)`) |
Save the file in exactly its declared `LANGUAGE_CHARSET`; an editor that rewrites it as UTF-8 will corrupt the non-ASCII bytes.
## Adding or updating a language
1. Copy `English.txt` to `<Language>.txt`, or edit the existing file.
2. Translate each second line; leave the English keys untouched.
3. Fill in the `LANGUAGE_*` header for a new file.
4. Open a pull request, or attach the file to a GitHub issue.
When new strings land in `English.txt` they show up untranslated (as English) until a translator fills them in.
