From 3aa428e50b6e0497018943b998d8d3e95baad3be Mon Sep 17 00:00:00 2001 From: Ingo Schwarze Date: Wed, 20 Aug 2014 01:09:04 +0000 Subject: 1.12.4 release notes --- NEWS | 466 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 466 insertions(+) create mode 100644 NEWS diff --git a/NEWS b/NEWS new file mode 100644 index 00000000..f2dacd34 --- /dev/null +++ b/NEWS @@ -0,0 +1,466 @@ +$Id: NEWS,v 1.6.2.1 2014/08/20 01:09:04 schwarze Exp $ + +The 1.12 branch is only adequate for systems requiring makewhatis(8) +and apropos(1) support but lacking either SQLite3 or fts(3). +Otherwise, please migrate to the 1.13 branch. +See the INSTALL file for details. + +This file lists the most important changes in the mdocml.bsd.lv distribution. + +Changes in version 1.12.4, released on August 20, 2014 +The following bugfixes are not yet contained in 1.13.1: + + * In the mdoc(7) parser, a NULL pointer dereference was fixed for .Bl + macros having no type and none of -width, -offset, or -compact + * In the mdoc(7) parser, a NULL pointer dereference was fixed that could + be triggered by invalid macro sequences like .Bl -hang .It Bo .Sh. + * In the mdoc(7) parser, an assertion crash was fixed that could be + triggered by stray .It macros right after .El. + * In the man(7) parser, a memory leak was fixed that could be triggered + by certain macros occurring at invalid positions inside .RS and .UR. + * In all formatters, interpretation of scaling units was corrected. + * In the escape sequence formatter, an out-of-bounds buffer read access + was fixed that could be triggered by certain invalid escape sequences. + +Changes in version 1.13.1, released on August 10, 2014 +The following changes are also contained in 1.12.4: + + --- MAJOR NEW FEATURES --- + * The roff(7) parser now provides an almost complete implementation + of numerical expressions. + * Warning and error messages have been improved in many ways. + Almost all fatal errors were downgraded to normal errors and some + even to warnings. Almost all messages now mention the macro where + the issue is detected and many indicate the workaround employed. + The mandoc(1) manual now includes a list explaining all messages. + --- MINOR NEW FEATURES --- + * The roff(7) parser now supports the .ami (append to macro with + indirectly specified name), .as (append to user-defined + string), .dei (define macro with indirectly specified name), + .ll (line length), and .rr (remove register) requests. + * The roff(7) parser now supports string comparison and numerical + conditionals in the .if and .ie requests. + * The roff parser now fully supports the \B (validate numerical + expression) and partially supports the \w (measure text width) + escape sequences. + * The terminal formatter now supports the \: (optional line break) + escape sequence. + * The roff parser now supports expansion of user-defined strings + involving indirect references. + * The roff(7) parser now handles some pre-defined read-only + number registers that occur in the pod2man(1) preamble. + * For backward compatibility, the mdoc(7) parser and formatters + now support the obsolete macros .En, .Es, .Fr, and .Ot. + * The mdoc(7) formatter non partially supports .Bd -centered. + * tbl(7) now handles leading and trailing vertical lines. + * The build system now provides fallback versions of strcasestr(3) + and strsep(3) for systems lacking them. + * The mdoc(7) manual now explains how various standards + supported by the .St macro are related to each other. + --- BUGFIXES --- + * In the roff(7) parser, several bugs were fixed with respect + to closing conditional blocks on macro lines. + * Parsing of roff(7) identifiers and escape sequences was improved + in multiple respects. + * In the mdoc(7) parser, the handling of defective document + prologues was improved in multiple ways. + * The mdoc(7) parser no longer skips content before the first section + header, and it no longer deletes non-.% content from .Rs blocks. + * In the mdoc(7) parser, a crash was fixed related to weird .Sh headers. + * In the mdoc(7) parser, handling of .Sm with missing or invalid + arguments was corrected. + * In the mdoc(7) parser, trailing punctuation at the end of partial + implicit macros no longer triggers end-of-sentence spacing. + * In the terminal formatter, two crashes were fixed: one triggered by + excessive indentation and another by excessively long .Nm arguments. + * In the terminal formatter, a floating point rounding bug was + fixed that sometimes caused an off-by-one error in indentation. + * In the UTF-8 formatter, rendering of accents, breakable hyphens, + and non-breakable spaces was corrected. + * In the HTML formatter, encoding of special characters was + corrected in multiple respects. + * In the mdoc(7) formatter, rendering of .Ex and .Rv was + improved for various edge cases. + * In the mdoc(7) formatter, handling of empty .Bl -inset item + heads was improved. + * In the man(7) formatter, some bugs were fixed with respect + to same-line detection in the context of .TP and .nf macros, + and the indentation of .IP and .TP blocks was improved. + * The mandoc(3) library no longer prints to stderr. + --- THANKS TO --- + Abhinav Upadhyay (NetBSD), Andreas Voegele, Anthony Bentley (OpenBSD), + Christian Weisgerber (OpenBSD), Havard Eidnes (NetBSD), Jan Stary, + Jason McIntyre (OpenBSD), Jeremie Courreges-Anglas (OpenBSD), + Joerg Sonnenberger (NetBSD), Juan Francisco Cantero Hurtado (OpenBSD), + Marc Espie (OpenBSD), Matthias Scheler (NetBSD), Pascal Stumpf (OpenBSD), + Paul Onyschuk (Alpine Linux), Sebastien Marie, Steffen Nurpmeso, + Stuart Henderson (OpenBSD), Ted Unangst (OpenBSD), Theo de Raadt (OpenBSD), + Thomas Klausner (NetBSD), and Ulrich Spoerlein (FreeBSD) + for reporting bugs and missing features. + +Changes in version 1.12.3, released on December 31, 2013 + + * In the mdoc(7) SYNOPSIS, line breaks and hanging indentation + now work correctly for .Fo/.Fa/.Fc and .Fn blocks. + Thanks to Franco Fichtner for doing part of the work. + * The mdoc(7) .Bk macro got some addititonal bugfixes. + * In mdoc(7) macro arguments, double quotes can now be quoted + by doubling them, just like in man(7). + Thanks to Tsugutomo ENAMI for the patch. + * At the end of man(7) macro lines, end-of-sentence spacing + now works. Thanks to Franco Fichtner for the patch. + * For backward compatibility, the man(7) parser now supports the + man-ext .UR/.UE (uniform resource identifier) block macros. + * The man(7) parser now handles closing blocks that are not open + more gracefully. + * The man(7) parser now ignores blank lines right after .SH and .SS. + * In the man(7) formatter, reset indentation when leaving a block, + not just when entering the next one. + * The roff(7) .nr request now supports incrementing and decrementing + number registers and stops parsing the number right before the + first non-digit character. + * The roff(7) parser now supports the alternative escape sequence + syntax \C'uXXXX' for Unicode characters. + * The roff(7) parser now parses and ignores the .fam (font family) + and .hw (hyphenation points) requests and the \d and \u escape + sequences. + * The roff(7) manual got a new ESCAPE SEQUENCE REFERENCE. + +Changes in version 1.12.2, released on Oktober 5, 2013 + + * The mdoc(7) to man(7) converter, to be called as mandoc -Tman, + is now fully functional. + * The mandoc(1) utility now supports the -Ios (default operating system) + input option, and the -Tutf8 output mode now actually works. + * The mandocdb(8) utility no longer truncates existing databases when + starting to build new ones, but only replaces them when the build + actually succeeds. + * The man(7) parser now supports the PD macro (paragraph distance), + and (for GNU man-ext compatibility only) EX (example block) and EE + (example end). Plus several bugfixes regarding indentation, line + breaks, and vertical spacing, and regarding RS following TP. + * The roff(7) parser now supports the \f(BI (bold+italic) font escape, + the \z (zero cursor advance) escape and the cc (change control + character) and it (input line trap) requests. Plus bugfixes regarding + the \t (tab) escape, nested escape sequences, and conditional requests. + * In mdoc(7), several bugs were fixed related to UTF-8 output of quoting + enclosures, delimiter handling, list indentation and horizontal and + vertical spacing, formatting of the Lk, %U, and %C macros, plus some + bugfixes related to the handling of syntax errors like badly nested + font blocks, stray Ta macros outside column lists, unterminated It Xo + blocks, and non-text children of Nm blocks. + * In tbl(7), the width of horizontal spans and the vertical spacing + around tables was corrected, and in man(7) files, a crash was fixed + that was triggered by some particular unclosed T{ macros. + * For mandoc developers, we now provide a tbl(3) library manual and + gmdiff, a very small, very simplistic groff-versus-mandoc output + comparison tool. + * Provide this NEWS file. + +Changes in version 1.12.1, released on March 23, 2012 + + * Significant work on apropos(1) and mandocdb(8). These tools are now + much more robust. A whatis(1) implementation is now handled as an + apropos(1) mode. These tools are also able to minimally handle + pre-formatted pages, that is, those already formatted by another + utility such as GNU troff. + * The man.cgi(7) script is also now available for wider testing. + It interfaces with mandocdb(8) manuals cached by catman(8). + HTML output is generated on-the-fly by libmandoc or internal + methods to convert pre-formatted pages. + * The mailing list archive for the discuss and tech lists are being + hosted by Gmane at gmane.comp.tools.mdocml.user and + gmane.comp.tools.mdocml.devel, respectively. + +Changes in version 1.12.0, released on October 8, 2011 + + * This version features a new, work-in-progress mandoc(1) output mode: + -Tman. This mode allows a system maintainer to distribute man(7) + media for older systems that may not natively support mdoc(7), such + as old Solaris systems. + * The -Ofragment option was added to mandoc(1)'s -Thtml and -Txhtml modes. + * While adding features, an apropos(1) utility has been merged from the + mandoc-tools sandbox. This interfaces with mandocdb(8) for semantic + search of manual content. apropos(1) is different from the traditional + apropos primarily in allowing keyword search (such as for functions, + utilities, etc.) and regular expressions. Note that the calling + syntax for apropos is likely to change as it settles down. + * In documentation news, the mdoc(7) and man(7) manuals have been + made considerably more readable by adding MACRO OVERVIEW sections, by + moving the gory details of the LANGUAGE SYNTAX to the roff(7) manual, + and by moving the very technical MACRO SYNTAX sections down to the + bottom of the page. + * Furthermore, for tbl(7), the -Tascii mode horizontal spacing of tables + was rewritten completely. It is now compatible with groff(1), both + with and without frames and rulers. + * Nesting of indented blocks is now supported in man(7), and several + bugs were fixed regarding indentation and alignment. + * The page headers in mdoc(7) are now nicer for very long titles. + +Changes in version 1.11.7, released on September 2, 2011 + + * Added demandoc(1) utility for stripping away macros and escapes. + This replaces the historical deroff(1) utility. + * Also improved the mdoc(7) and man(7) manuals. + +Changes in version 1.11.6, released on August 16, 2011 + + * Handling of tr macro in roff(7) implemented. This makes Perl + documentation much more readable. Hyphenation is also now enabled in + man(7) format documents. Many other general improvements have been + implemented. + +Changes in version 1.11.5, released on July 24, 2011 + + * Significant eqn(7) improvements. mdocml can now parse arbitrary eqn + input (although few GNU extensions are accepted, nor is mixing + low-level roff with eqn). See the eqn(7) manual for details. + For the time being, equations are rendered as simple in-line text. + The equation parser satisfies the language specified in the + Second Edition User's Guide: + http://www.kohala.com/start/troff/v7man/eqn/eqn2e.ps + +Changes in version 1.11.4, released on July 12, 2011 + + * Bug-fixes and clean-ups across all systems, especially in mandocdb(8) + and the man(7) parser. This release was significantly assisted by + participants in OpenBSD's c2k11. Thanks! + +Changes in version 1.11.3, released on May 26, 2011 + + * Introduce locale-encoding of output with the -Tlocale output option and + Unicode escaped-character input. See mandoc(1) and mandoc_char(7), + respectively, for details. This allows for non-ASCII characters (e.g., + \[u5000]) to be rendered in the locale's encoding, if said environment + supports wide-character encoding (if it does not, -Tascii is used + instead). Locale support can be turned off at compile time by removing + -DUSE_WCHAR in the Makefile, in which case -Tlocale is always a synonym + for -Tascii. + * Furthermore, multibyte-encoded documents, such as those in UTF-8, may + be on-the-fly recoded into mandoc(1) input by using the newly-added + preconv(1) utility. Note: in the future, this feature may be + integrated into mandoc(1). + +Changes in version 1.11.2, released on May 12, 2011 + + * Corrected some installation issues in version 1.11.1. + * Further migration to libmandoc. + * Initial public release (this utility is very much under development) + of mandocdb(8). This utility produces keyword databases of manual + content, which features semantic querying of manual content. + +Changes in version 1.11.1, released on April 4, 2011 + + * The earlier libroff, libmdoc, and libman soup have been merged into + a single library, libmandoc, which manages all aspects of parsing + real manuals, from line-handling to tbl(7) parsing. + * As usual, many general fixes and improvements have also occurred. + In particular, a great deal of redundancy and superfluous code has + been removed with the merging of the backend libraries. + * see also the changes in 1.10.10 + +Changes in version 1.10.10, March 20, 2011, NOT released + + * Initial eqn(7) functionality is in place. For the time being, + this is limited to the recognition of equation blocks; + future version of mdocml will expand upon this framework. + +Changes in version 1.10.9, released on January 7, 2011 + + * Many back-end fixes have been implemented: argument handling (quoting), + man(7) improvements, error/warning classes, and many more. + * Initial tbl(7) functionality (see the "TS", "TE", and "T&" macros in + the roff(7) manual) has been merged from tbl.bsd.lv. Output is still + minimal, especially for -Thtml and -Txhtml, but manages to at least + display data. This means that mandoc(1) now has built-in support + for two troff preprocessors via libroff: soelim(1) and tbl(1). + +Changes in version 1.10.8, released on December 24, 2010 + + * Overhauled the -Thtml and -Txhtml output modes. They now display + readable output in arbitrary browsers, including text-based ones like + lynx(1). See HTML and XHTML manuals in the DOCUMENTATION section + for examples. Attention: available style-sheet classes have been + considerably changed! See the example.style.css file for details. + Lastly, libmdoc and libman have been cleaned up and reduced in size + and complexity. + * see also the changes in 1.10.7 + +Changes in version 1.10.7, December 6, 2010, NOT released + + Significant improvements merged from OpenBSD downstream, including: + * many new roff(7) components, + * in-line implementation of troff's soelim(1), + * broken-block handling, + * overhauled error classifications, and + * cleaned up handling of error conditions. + +Changes in version 1.10.6, released on September 27, 2010 + + * Calling conventions for mandoc(1) have changed: -W improved and -f + deprecated. + * Non-ASCII characters are also now uniformly discarded. + * Lots of documentation improvements. + * Many incremental fixes accomodating for groff's more interesting + productions. + * Lastly, pod2man(1) preambles are now fully accepted after some + considerable roff(7) and special character support. + +Changes in version 1.10.5, released on July 27, 2010 + + * Primarily a bug-fix and polish release, but including -Tpdf support + in mandoc(1) by way of "Summer of Code". Highlights: + * fix "Sm" and "Bd" handling + * fix end-of-sentence handling for embedded sentences + * polish man(7) documentation + * document all mdoc(7) macros + * polish mandoc(1) -Tps output + * lots of internal clean-ups in character escapes + * un-break literal contexts in man(7) documents + * improve -Thtml output for -man + * add mandoc(1) -Tpdf support + +Changes in version 1.10.4, released on July 12, 2010 + + * Lots of features developed during both "Summer of Code" and the + OpenBSD c2k10 hackathon: + * minimal "ds" roff(7) symbols are supported + * beautified SYNOPSIS section output + * acceptance of scope-block breakage in mdoc(7) + * clarify error message status + * many minor bug-fixes and formatting issues resolved + * see also changes in 1.10.3 + +Changes in version 1.10.3, June 29, 2010, NOT released + + * variable font-width and paper-size support in mandoc(1) -Tps output + * "Bk" mdoc(7) support + +Changes in version 1.10.2, released on June 19, 2010 + + * Small release featuring text-decoration in -Tps output, + a few minor relaxations of errors, and some optimisations. + +Changes in version 1.10.1, released on June 7, 2010 + + * This primarily focusses on the "Bl" and "It" macros described in + mdoc(7). Multi-line column support is now fully compatible with groff, + as are implicit list entries for columns. + * Removed manuals(7) in favour of http://manpages.bsd.lv. + * The way we handle the SYNOPSIS section (see the SYNOPSIS documentation + in MANUAL STRUCTURE) has also been considerably simplified compared + to groff's method. + * Furthermore, the -Owidth=width output option has been added to -Tascii, + see mandoc(1). + * Lastly, initial PostScript output has been added with the -Tps option + to mandoc(1). It's brutally simple at the moment: fixed-font, with no + font decorations. + +Changes in version 1.10.0, released on May 29, 2010 + + * Release consisting of the results from the m2k10 hackathon and up-merge + from OpenBSD. This requires a significant note of thanks to Ingo + Schwarze (OpenBSD) and Joerg Sonnenberger (NetBSD) for their hard work, + and again to Joerg for hosting m2k10. Highlights (mostly cribbed from + Ingo's m2k10 report) follow in no particular order: + * a libroff preprocessor in front of libmdoc and libman stripping out + roff(7) instructions; + * end-of-sentence (EOS) detection in free-form and macro lines; + * correct handling of tab-separated columnar lists in mdoc(7); + * improved main calling routines to optionally use mmap(3) for better + performance; + * cleaned up exiting when invoked as -Tlint or over multiple files + with -fign-errors; + * error and warning message handling re-written to be unified for + libroff, libmdoc, and libman; + * handling of badly-nested explicit-scoped macros; + * improved free-form text parsing in libman and libmdoc; + * significant GNU troff compatibility improvements in -Tascii, + largely in terms of spacing; + * a regression framework for making sure the many fragilities of GNU + troff aren't trampled in subsequent work; + * support for -Tascii breaking at hyphens encountered in free-form text; + * and many more minor fixes and improvements + +Changes in version 1.9.25, released on May 13, 2010 + + * Fixed handling of "\*(Ba" escape. + * Backed out -fno-ign-chars (pointless complexity). + * Fixed erroneous breaking of literal lines. + * Fixed SYNOPSIS breaking lines before non-initial macros. + * Changed default section ordering. + * Most importantly, the framework for end-of-sentence double-spacing is + in place, now implemented for the "end-of-sentence, end-of-line" rule. + * This is a stable roll-back point before the mandoc hackathon in Rostock! + +Changes in version 1.9.24, released on May 9, 2010 + + * Rolled back break-at-hyphen. + * -DUGLY is now the default (no feature splits!). + * Free-form text is not de-chunked any more: lines are passed + whole-sale into the front-end, including whitespace. + * Added mailing lists. + +Changes in version 1.9.23, released on April 7, 2010 + + * mdocml has been linked to the OpenBSD build. + * This version incorporates many small changes, mostly from patches + by OpenBSD, allowing crufty manuals to slip by with warnings instead + of erroring-out. + * Some subtle semantic issues, such as punctuation scope, have also + been fixed. + * Lastly, some issues with -Thtml have been fixed, which prompted an + update to the online manual pages style layout. + +Changes in version 1.9.22, released on March 31, 2010 + + * Adjusted merge of the significant work by Ingo Schwarze + in getting "Xo" blocks (block full implicit, e.g., "It" + for non-columnar lists) to work properly. This isn't + enabled by default: you must specify -DUGLY as a compiler + flag (see the Makefile for details). + +Changes in version 1.9.20, released on March 30, 2010 + + * More efforts to get roff instructions in man(7) documents under + control. Note that roff instructions embedded in line-scoped, + next-line macros (e.g. "B") are not supported. + * Leading punctuation for mdoc(7) macros, such as "Fl ( ( a", + are now correctly handled. + +Changes in version 1.9.18, released on March 27, 2010 + + * Many fixes (largely pertaining to scope) + and improvements (e.g., handling of apostrophe-control macros, + which fixes the strange "BR" seen in some macro output) + to handling roff instructions in man(7) documents. + +Changes in version 1.9.17, released on March 25, 2010 + + * Accept perlpod(1) standard preamble. + * Also accept (and discard) "de", "dei", "am", "ami", and "ig" + roff macro blocks. + +Changes in version 1.9.16, released on March 22, 2010 + + * Inspired by patches and bug reports by Ingo Schwarze, + allowed man(7) to accept non-printing elements to be nested + within next-line scopes, such as "br" within "B" or "TH", + which is valid roff. + * Longsoon architecture also noted and Makefile cleaned up. + +Changes in version 1.9.15, released on February 18, 2010 + + * Moved to our new BSD.lv home. + * XHTML is now an acceptable output mode for mandoc(1); + * "Xr" made more compatible with groff; + * "Vt" fixed when invoked in SYNOPSIS; + * "\\" escape removed; + * end-of-line white-space detected for all lines; + * subtle bug fixed in list display for some modes; + * compatibility layer checked in for compilation in diverse + UNIX systems; + * and column lengths handled correctly. + +For older releases, see the ChangeLog files +in http://mdocml.bsd.lv/snapshots/ . -- cgit v1.2.3-56-ge451
