reslog change log 2022-03-19 1. Added support for the xz compression. 2. Replaced Compress::Zlib with IO::Compress::Gzip and IO::Uncompress::Gunzip. 3. Replaced Compress::Bzip2 with IO::Compress::Bzip2 and IO::Uncompress::Bunzip2. 2020-02-06 version 3.17 1. Replaced the messy GNU-styled, multi-lingual documents with a single Markdown README.md. 2. Added the GitHub repository to the document, and removed the SourceForge website, my web page, and the SourceForge mailing list from the document. 3. Removed the document license, and my PGP key from the package. Removed the signature file from the repository. 4. Changed the license from GPLv3 to APLv2. 5. Various fixes to avoid JetBrains IDE problem detection. 2020-02-01 arclog is hosted on GitHub now. 2008-11-18 1. INSTALL and reslog.en.html: Fixed the grammar on installation with the CPAN or CPANPLUS shell, changed "install with the CPAN shell using" and "install with the CPANPLUS shell using" to "install it with the CPAN shell by running" and "install it with the CPANPLUS shell by running". 2. INSTALL* and reslog.*.html: Changed "Fedora/Red Hat" to "Red Hat/Fedora/CentOS". 2008-11-17 1. INSTALL and reslog.en.html: Fixed the grammar on required and optional module installation, changed "install using" and "install this using" to "install it by running". 2008-11-15 1. reslog.*.html: Fixed so that installation from source and with shells are joint into one sentence. 2008-11-12 1. INSTALL*, reslog.*.html: Updated information on optional Perl modules, to describe different installation commands for different operating systems. 2008-11-11 1. reslog: Fixed the _private::ProgressBar class so that it does not use() Term::ReadKey, but require() it at object initialization. This enables it to work when Term::ReadKey is missing. 2. reslog: Fixed the update() method of the _private::ProgressBar class, to accept a dynamic label. 2008-09-30 1. reslog: Update the update() method of the the _private::ProgressBar class too use the bracket characters instead of the pipe character for a better visual outlook. 2008-09-29 1. reslog: Use the _private::ProgressBar class in replace of the show_progress() function to display the progress bar. This makes the progress bar easier and more pretty. 2008-04-21 1. INSTALL and reslog.en.html: Fixed typo: "instalation" to "installation". 2007-12-05 1. reslog: Initialize the static variables within BEGIN {...} blocks for all _private::* classes. 2. NEWS: Added. The NEWS file is quite useful in addition to the Changes change log. 3. reslog.*.html: Refer to NEWS instead of Changes for release notes. 2007-12-04 version 3.16 Fixed a bug with empty files created with Compress::Bzip2. 1. Makefile.PL: Fixed to prevent importing symbols when checking optional prerequisites. 2. reslog: Fixed the check_type() method of the _private::LogFile class, so that empty files are checked with the file name suffix, too. This solve the issue that Compress::Bzip2 creates empty files which confuse further processing on file name suffix stripping. 2007-12-03 1. Build.PL: Fixed the comment. This file is "Build.PL", not "Makefile.PL". 2. Build.PL: Added "use warnings;". 2007-12-03 version 3.15 Build system fix. 1. Makefile.PL: Fixed the required Perl version from "use 5.006" to "use 5.008;". reslog requires Perl 5.8.0 to work. 2007-12-03 version 3.14 Documentation and test suite fixes. 1. reslog.zh-tw.html, reslog.zh-cn.html: Revised the Chinese text on "3-argument open()" so that it is more readable. 2. t/_helper.pm: Increased time zone range from -1200 to +1400 in the mkrandlog_normal() and mkrandlog_noip() subroutines. 3. t/_helper.pm: Version number increased to 0.05. 4. t/_helper.pm: Fixed time zone text generation in the mkrandlog_normal() and mkrandlog_noip() subroutines, using "%+05d" instead of "%+03d%02d" so that we will get a correct representation in time zones +0030 and -0030. 5. t/03-errors.t: Fixed the title of the "a same log file specified more than once" test. 6. reslog.*.html: Added ... to the description. 2007-12-03 version 3.13 1. t/03-errors.t: Added. 2. t/reslog.*.html: Revised. 3. t/_helper.pm: Fixed the way deal with time zone in the mkrndlog_normal() and mkrndlog_noip() subroutines, using gmtime($t + $tz) instead of calculating time zone offset with $tz + (timegm(localtime)-timelocal(localtime)). This is the easy and right way to do. 4. reslog.zh-tw.html, TODO.zh-tw, TODO.zh-cn: Changed '繁體中文' to '正體中文'. 2007-12-02 1. t/02-several.t: Added, to replace the t/04-hybrix.t. 2. t/04-hybrix.t: Removed 2007-12-01 1. reslog: Use "use 5.008" instead of "use 5.8.0", for compatibility with older Perl, and get ride of the warning of Perl 5.10. 2007-11-30 1. reslog, reslog.*.html: The default keep mode in the documentation is "restart", but it is actually running "delete" in the source code and in the test suite. The documentation is fixed to "delete" according to the actual program behavior. 2. t/_helper.pm: Renamed the mkrndlog() subroutine to mkrndlog_normal(). Renamed the mknoiprndlog() subroutine to mkrndlog_noip(). Added the mkrndlog_empty() subroutine. 3. reslog: Added check on whether the suffix to be appended is the same to the suffix to be trimmed. This cause the same file be overwritten as the resolved result. 4. t/01-exhaust.t: Combining t/01-plain.t, t/02-gzip.t, t/03-bzip2.t 2007-11-27 1. Makefile.PL, Build.PL: Clean-up old file found message. 2. Makefile.PL: Added message for optional prerequisites. 3. reslog.zh-tw.html, reslog.zh-cn.html: Tag the languages. 2007-11-26 1. t/_helper.pm, t/*.t: Updated the license to GPLv3. 2. README.zh-tw, README.zh-cn: File "Changes.zh-tw" and "Changes.zh-cn" no longer exists. Fixed as "Changes". 3. fdl.txt: Added. 4. MSWin32 and MS-Win32 is now written as MS-Windows in the documentation. 5. reslog: Reorder the debug message in the check_gzip() and check_bzip2() methods of the _private::IO class. 6. Makefile.PL, Build.PL: Fixed comment typo. ("any old files") 7. Build.PL: Added "recommends" and "build_requires". 2007-11-25 1. reslog.en.html, INSTALL: Fixed the typo "archieve" as "archive". 2. reslog: Fixed to return ref($GZIP_IO)->new instead of $GZIP_IO in the check_gzip() method, ref($BZIP2_IO)->new instead of $BZIP2_IO in the check_bzip2() method of the _private::IO class, so that a same I/O handler will not be returned to different log files. 2007-11-22 1. reslog: Fixed $SIG{__WARN__} to $SIG{"__WARN__"} in the parse_args() subroutine. 2007-11-20 1. t/_helper.pm: Added the randip() subroutine to provide random IP that has reliable reverse-lookup DNS. 2007-11-19 1. t/_helper.pm: Fixed the flist() subroutine to exclude non-files. 2. t/_helper.pm, t/*.t: Add the prsrvsrc() subroutine to preserve the source file for debugging. 3. t/_helper.pm, t/*.t: Add the cleanup() subroutine to clean-up the test directory after success or failure. 4. t/*.t: Removed the strange escaping of double-quotation character of reslog path. 2007-11-18 1. reslog: Move the TYPE_PLAIN, TYPE_GZIP and TYPE_BZIP2 constants from the _private::LogFile package to the main package, so that other packages can use it, too. 2. t/_helper.pm: Added the TYPE_PLAIN, TYPE_GZIP and TYPE_BZIP2 constants for easier use. 3. reslog: Clean up File::Spec::Functions references. 4. Makefile.PL and Build.PL: Changed the clean-up list from "t/log/*" to "t/log*". 2007-11-17 1. _helper.pm: Moved rel2abs() from a method of the _private::LogFile class to a utility subroutine of the main package. rel2abs() may be used elsewhere. 2007-11-15 1. UPGRADE, UPGRADE.zh-tw, UPGRADE.zh-cn: Removed the outdated file location change for version 3.02 or earlier. The file location has changed later. The old change is meaningless. 2. UPGRADE, UPGRADE.zh-tw, UPGRADE.zh-cn: Added "perl Build.PL" to the file location change instruction. 3. UPGRADE.zh-tw, UPGRADE.zh-cn: Added Chinese translation to the reason of the script name change. 4. t/_helper.pm: Update the style of mkrndlog() and mknoiprndlog(). Added more status, adjusting more possibility to HTTP/1.1 and status 200. Fixed the comment that host type 1 is IP and 0 is domain name. 5. t/_helper.pm: Added a random URL generator to mkrndlog() and mknoiprndlog(). 6. t/_helper.pm: Removed rmalldir() and mkcldir(), and replaced with mkpath() and rmtree() from File::Path. 2007-11-14 1. reslog: Moved the check_gzip() method and the check_bzip2() method from the _private::LogFile package to the _private::IO package, so that it can be used by other packages, and removed the $self variable. It is not used anyway. The 2 methods are called as static methods now. 2. reslog: Renamed the new_read() method as open_read(), the new_write() method as open_write(), the new_append() method as open_append(). Replaced the strange architect that start a new instance with $ioclass, with reusing the same $io object. 3. reslog: Renamed the new_read() method as open_read(), the new_write() method as open_write(), the new_append() method as open_append(). Replaced the strange architect that start a new instance with $ioclass, with reusing the same $io object. 4. reslog: Changed " -- " to " - " in comment. 5. reslog: Changed "Deal the ~ home directories under UNIX" to "Deal with the ~ user home directories under UNIX", "If start from user's home directory" to "If it starts from the user home directory". 6. reslog: Fixed the rel2abs() method so that it use getpwuid() instead of getlogin(), and respect the HOME environment variable for the current user. 7. reslog: Fixed parse_args() to treat "/dev/stdin" as STDIN on UNIX-like systems. 8. reslog: Fixed parse_args() and removed the duplicated short help on Getopt::Long::GetOptions errors. 9. reslog: Fixed show_progress() to reset the clean-up the start time when progress is finished. 2007-07-23 version 3.12 Fixed the error when there is no IP to be resolved. 1. reslog: Fixed the "division by zero" error when there is no IP to be resolved. 2. _helper.pm: Added subroutine mknoiprndlog($) to create random log files without any IP. 3. t/01-plain.t, t/02-gzip.t, t/03-bzip2.t: Added test 15 and 16 to test resolving empty log files. 2007-07-23 version 3.11 Fixed problem with systems without useithreads, fixed bug checking STDIN file type with the file program, moved files back to the Perl default installation directories, and added support for installation with Module::Build. 1. Build.PL: Added to support installation with Module::Build. 2007-07-22 1. reslog.en.html: Updated "Internet Protocol" as "internet protocol" in abbreviation title. 2. reslog: Fixed the new() method of the _private::LogFile::STDIN class, to run unlink0() after checking the file type, to fix the issue that file was removed before checking the file type with the file program 3. reslog: Fixed _private::Resolver::Threaded, to load threads in eval() and define share() when threading is not available, in order to work with systems that are not compiled with useithreads. 2007-07-22 version 3.10 Documentation fixes. 1. Removed pod2htmd.tmp, pod2htmi.tmp from distribution. 2007-07-21 1. reslog.html: HTML fixes for accessibility, correct HTML character references, HTML numeric references, author information and so on. 2. Changes: Version number 3.10 was updated as 3.09. I was planning to bounce the version to 3.10, but forgot this and tagged 3.09 everywhere. Well, then let it be 3.09 anyway. 2007-07-21 version 3.09 License updated to GPLv3, and various fixes. 1. INSTALL and reslog.html: Replace Term::Size with Term::ReadKey. 2. Changes.zh-tw and Changes.zh-cn: Removed. 3. License updated to GPLv3. 4. COPYING.zh-tw and COPYING.zh-cn: Removed since official translation of GPLv3 is not available yet. 5. Removed stupid "All rights reserved" from the copyright notice. It shouldn't appear from the beginning. 6. Makefile.PL: Rearranged the order, and added LICENSE and SIGN. 2006-06-12 1. reslog: new() method of _private::LogFile class now opens the log file and bounces there, instead of checking the log file first. This way we will return localed system error message. 2. reslog: new() method of _private::LogFile class now opens the log file in read-only mode when keep all. 2. reslog: check_type() method of _private::LogFile class now returns the type instead of setting $self->{"type"}, for code readability. 2006-06-11 1. reslog: new() method of _private::LogFile class now initialized STDIN with _private::LogFile::STDIN class, instead of bouncing. parse_args() subroutine does not initialize the files twice now. 2. reslog: Upper-case the error messages in _private::LogFile. 3. reslog: check_io() method of _private::LogFile class now returns the IO object instead of setting $self->{"io"}, for code readability. 4. reslog: Fixed _private::LogFile::STDIN::new() method that we passed an extra empty argument to tempfile(). 5. reslog: Fixed comment, use "handler" instead of "handle". 2006-06-08 1. reslog: Revised the code with my own coding standard. 2. reslog: Added "bundling" to Getopt::Long::Configure(). This might introduce option-processing incompatibility. 3. reslog: Replaced Term::Size and Win32::Console with Term::ReadKey. Term::ReadKey seems to be more recent and portable. 2006-05-28 1. INSTALL and reslog.html: Fixed the bzip2 website address. 2005-05-22 version 3.08 Documentation fixes. 1. The last update of the HTML documents are fixed. 2. Changes: English change log was gone. (Maybe lost when cut-and-paste?) A correct one is supplied. 2005-05-22 version 3.07 1. reslog: No more checks on the availability of STDIN and STDOUT, and no more dummy replacement created if not. It was originally to solve perl.cpan.testers 202971 when running with CPANPLUS under MSWin32, duplicating closed STDIN causes errors. But I was going the wrong way. I was testing STDIN/STDOUT/STDERR redirection in shell backticks. Whether CPANPLUS closes STDIN or not should be irrelevant. It may be a issue of the shell backticks itself. Anyhow I rewrote the testing executing method and it is solve. In fact, it's still not working when STDIN and STDOUT is unavailable. But IPC::Open3 won't work on that, too. It should be safe to be ignored. 2. t/_helper.pm: runcmd() was rewritten. It now run the command with pipe open instead of shell backticks. It's API is hence changed. 3. t/_helper.pm: frread() and frwrite() are added to do raw file read-write. 4. t/01-plain.t, t/02-gzip.t, t/03-bzip2.t, t/04-hybrix.t: Edited for the new runcmd() API. 5. t/_helper.pm: Unused subroutines cp() and rm() are removed. 6. t/01-plain.t, t/02-gzip.t, t/03-bzip2.t, t/04-hybrix.t: Added "use diagnostics;" to help debugging. 7. Successfully tested and run under Linux 2.4 i686, Linux 2.6 i686, Linux 2.4 AMD64, FreeBSD, Solaris, MacOSX Darwin, MSWin32 and cygwin. (Thanks to SourceForge compile farm for providing testing platforms.) 8. THANKS, THANKS.zh-tw, THANKS.zh-cn: Edited. 2005-05-19 1. reslog: Use stat() to check whether STDIN and STDOUT are available, instead of duplicate them and check if success directly. This avoids the problem on MacOSX Darwin where trying to duplicate unopened STDIN crashes directly instead of dies that can be caught by eval(). 2. t/01-plain.t, t/02-gzip.t, t/03-bzip2.t, t/04-hybrix.t: Add option -d -d -d for more debug information when failures occur. 2. t/_helper.pm: Prepend the command line to the STDERR result to ease debugging. 2005-05-18 Solaris fix. 1. The file executable on Solaris does not accept file content from STDIN. This is solved. The target file name is passed to the file executable. When reading from STDIN in this case, a named temporary file is created for this and deleted whenever possible. 2. t/01-plain.t, t/02-gzip.t, t/03-bzip2.t, t/04-hybrix.t: Use updir for composing the script name in the old way, but not popping splitdir(). $FindBin::Bin may return a directory ended with a slash which become an empty part in splitdir. (Fedora 3 on AMD64) 3. Tested on Sparc/Solaris, FreeBSD, Fedora 3 on AMD64. 4. t/01-plain.t, t/02-gzip.t, t/03-bzip2.t, t/04-hybrix.t: Setting wrong testing parameter. -t 1 should be -n 1. 5. reslog: Checks on whether flock() success or not are removed. In some specific situation flock() is simply not available. For example, MacOSX Darwin has flock() on local file systems, but not over NFS. It's not possible to detect and avoid all these situation. 2005-05-17 1. pgpkey.asc: Updated with the new identity with UTF-8 names. 2005-05-16 version 3.06 1. t/99-pod.t added to test the POD document with Test::Pod. 2. t/01-plain.t, t/02-gzip.t, t/03-bzip2.t: Added test for failures on existing temporary files. 3. t/_helper.pm: Added prevention of generating IP 127.0.0.1. 4. reslog: Added package _private::Filter and move _private::Resolver::parse_line() and _private::Resolver::replace_line() there, to allow easier implementing different log file formats. Like GeoIP, or maybe MS-Extended, in the future. 5. reslog: Fixed the POD document. Section of links L<...> should be section headings in the document, but not manpage sections. This is fixed. Web site URLs are added to the AUTHOR section. Mailing list URL is added to the BUGS section. 2005-05-15 Test suite fix. 1. t/02-gzip.t, t/03-bzip2.t: Tests that weren't skipped when gzip or bzip2 is not available is fixed. (perl.cpan.testers 205969) 2. t/01-plain.t, t/02-gzip2.t, t/03-bzip2.t, t/04-hybrix.t: $nofile replaced $hasfile. $nogzip replaced $hasgzip. $nobzip2 replaced $hasbzip2. Skipping reason supplied. 3. reslog: devnull is used instead of tempfile when STDIN or STDOUT is not available. 4. reslog: Not only STDIN, but all files are checked if they are specified more than once. 5. t/MyHelper.pm: Subroutines thisfile(), rmalldir(), mkcldir(), fwrite(), whereis(), ftype(), flist(), mkrndlog(), randword() are added. Subroutine readfile() is renamed as fread(). Prototype cplist() is corrected as cp(). Subroutine rm() is removed. 6. t/01-plain.t, t/02-gzip2.t, t/03-bzip2.t, t/04-hybrix.t: I joined subtests together and shrank the total number of tests. They should be one tests anyway. This way I can test more on the result. 7. t/MyHelper.pm: flist() is added so that I can test if the resulted files list is correct. Several subtests on whether a file exists are removed. 8. t/MyHelper.pm: ftype() is added so that I can test if the resulted file format is correct. 9. t/MyHelper.pm: mkrndlog() is added to generate random Apache access_log files. No more sample log files shipped anymore. The test result should be better, too, since the content of the test log files vary now. The content of the shipped samples are all the same in fact. 10. t/MyHelper.pm: Renamed to _helper.pm, to avoid CPAN namespace pollution. 2005-05-08 Bug fix. 1. STDIN and STDERR are checked for availability first, and create dummy ones if they are not available. This fixed the bugs that on MSWin32 when STDIN is not opened, redirecting unopened STDIN caused error. This is the situation running "make test" in CPANPLUS. (perl.cpan.testers 202971) 2005-05-08 version 3.04 1. Fixed a typo when loading File::MMagic that prevent itself from loading File::MMagic 2005-05-08 version 3.03 1. flock() policy is redesigned. Now all the file handles that are not opened to ordinary files are not locked. Lock is released when when file handle is accessed with a foreign program. Files handles are always locked when opened to ordinary files and accessed internally, even for anonymous temporary files. This simplified the locking problem. How foreign programs access file handles are not an issue anymore. 2. Makefile.PL: MY package is added. Makefile target "upgrade" is added to remove the old files. constants() and manifypods() methods are added to alter the default install location. Now we default to install to /sbin directory and as manpage section 8. That is what I want. 3. BUGS and TODO section of the embedded POD document updated. 2005-05-02 version 3.02 1. _private::Resolver and _private::Resolver::Threaded are added. Resolver is independent from the main program so that other log file filter can use the same code with least modification (GeoIP, for example). 2. Help text on temporary working file updated. 3. Unsupported file format error message was using $type, which should be $_. This is fixed. 4. Test 31-39 added to test --suffix and --trim-suffix. 5. Tested with cygwin. 6. Quotes added to the test suite to avoid problem when make test in directories whose names may contain spaces. 7. Required Perl version changed to 5.8.0. 5.7.2 is a development version. It's meaningless to require that. 2005-05-01 version 3.0102 1. check_magic(), check_gzip() and check_bzip2() now check the return value of eval() directly, instead of saving it in $ok and check that. 2. %CONF is introduced to save the configuration. 3. $THIS_FILE, $SHORTHELP and $VERBOSE are moved from "use vars qw(...)" to "our (...)", to ease program management. 4. DEFAULT_PROGBAR is introduced to handle the default display status of the progress bar. 2005-05-01 version 3.0101 Labours' Day! 1. Package name changed from ResLog to main, to avoid polluting the CPAN namespace. 2. Class names changed from ResLog::* to _private::*, to avoid polluting the CPAN namespace. 3. check_io() returns an I/O interface object instead of an I/O type constant, so that the I/O handler object can be generated from it directly. new_read(), new_write() and new_append() now returns an I/O handler object generated from the I/O interface object. 4. use_flock() is added to IO::* I/O handlers to see if flock() is to be used on I/O handlers, to replace run-time checks. Currently bzip2 on MSWin32 should not use flocks(). 5. The constants IO_* are removed. 6. whereis() now uses ExtUtils::MakeMaker MM->maybe_command() to find the executable. This is inspired from CPAN::FirstTime. 2005-04-26 1. Changes: File edited to widen line limit from 60 columns to 79 columns, to ease reading. 2005-04-26 version 3.01 Bug fix. 1. --suffix and --trim-suffix was not working. I mistakenly put $_[0] instead of $_[1] in the GetOptions() and this wasn't tested! ^^; This is fixed. 2. Correct a typo in the documentation ("rewrite" should be "rewrote"). 3. Fixed a mistake that Changes.zh-tw was not updated with Changes.zh-cn. 2005-04-26 version 3.00 1. README updated 2. HTML documentation updated. 3. Uploaded to CPAN. 4. HTML documents updated to conform to W3C Web Content Accessibility Guide 1.0 Triple-A now. 2005-04-26 version 2.9901 1. INSTALL rewritten. 2. UPGRADE added. 2005-04-25 1. Module::Signature SIGNATURE gpg signature file added. The external gpg signature file is no longer used. 2. Test suite added. 3. Many bugs fixed, thanks to the test suite. 2005-04-24 version 2.99 This is a new object-oriented version. I rewrote the whole script from an empty file. 1. Rewrite everything in object-oriented style. 2. ithread threading support is added. With threading it can check several IP at the same time, dramatically reducing the time cost. This requires Perl 5.7.2 ithread support. New option --num-threads is added for this. You can see the effect by running with -d -d. 3. Supports for running gzip executable, running Compress::Bzip2, running bzip2 executable are added. This is the benefit of object-oriented programming. Log entry read/write is now done through an uniformed I/O handler API. This eased the addition of new I/O handlers. 4. New option --trim-suffix is added to remove certain file name suffix before appending our suffix, so that reslog can line-up with other log file post-processors. 5. file utility can be used instead of File::MMagic if that is not available. 6. Term::Size is used to display the progress bar under UNIX. Under MSWin32 Win32::Console will be used instead. reslog can run without them, but you won't see the progress bar. 7. Instead of resolving line by line, reslog now collects all the IP found on all the source log files first, resolve those IP altogether, and replace the IP with the resolved domain name in the log entries at one time. 8. The script and project name changed from "reslog.pl" to "reslog". A dot "." in the project name is not valid everywhere, like SourceForge. "reslog" is enough for a script name under UNIX. MSWin32 users won't run it with explorer file association anyway, and there is a pl2bat to turn reslog to reslog.bat. 9. Installation method is changed from my own Install.PL to Perl's standard ExtUtils::MakeMaker. Utilizing standard is a good thing. Perl's ExtUtils::MakeMaker is more portable than GNU's autoconf. As a result, reslog is installed into /usr/bin instead of /usr/sbin under UNIX. Of course, reslog don't need installation at all. :p 10. Version number is changed from 3 digits (2.1.0) to 2 digits (3.00), according to the Perl module convention. 11. ChangeLog is renamed as Changes, as what ExtUtils::MakeMaker expects. 2003-01-04 1. File handler EOF read checks were fixed with defined(). 2002-11-13 1. Long statistic lines are split for easy reading. 2. open_src() was rewritten according to open_src() in arclog.pl, in order to use compression with gzip and bzip2 binary executables. 2002-11-12 1. RELEASE_NOTES was renamed as ChangeLog. 2. AUTHORS was added. 3. THANKS was added. 4. The option checking logic was rewritten. 5. Fixed several places where $WORKING_SRC was not locked when created with tempfile. 6. Fixed several places where spaces are between function name and its opening parenthesis, according to perlstyle(1). 7. Unnecessary parenthesis after slice and catfile were removed. 2002-10-28 1. Fixed a bug that $WORKING_RES was not locked when opened. But it is unlocked when closed. On some systems (like Linux) you can request unlock on a file handle that is not previous locked, but on some others (like MSWin32) requesting unlock on a file handle that is not previous locked will cause error. $WORKING_RES doesn't really need locking at all. It is an anonymous temporary file handle, that can be accessed by this same working process only. It has no risk of simultaneously writing without threading, and I'm not doing threading here. I just lock it for a consistent programming style. (Thanks to Chen-hsiu Huang for reporting this.) 2002-09-28 1. File::MMagic and file are now used to check the file type, in addition to the file name suffix, with a more preferred order. 2. check_file_type() was added to check the file types by either File::MMagic or file. 3. check_gzip() was added to check the gzip method to use. 4. check_bzip2() was added to check the bzip2 method to use. 2002-09-18 version 2.1.0dev2 SourceForge Memorial Release. It's my first time to apply a project from SourceForge. Mostly are corrections to the documentation. SourceForge's project page is added to the available download source here. 1. reslog.pl's official home page at Tavern IMACAT's was restored. 2. The previous version was renamed from 2.1.0-dev1 to 2.1.0dev1, in order to unify the version number theme. 3. The project space at SourceForge was applied. Package files are uploaded to SourceForge now. 4. Project virtual host at SourceForge was set up. 5. SourceForge was added into the documentation as an official website and download source. 6. Documentation were corrected. Too many places were corrected. Ignored. 7. HTML document was rewritten to accommodate XHTML 1.1 recommendation. 2002-08-31 version 2.1.0dev1 Rewrite after almost 1 year, to be run on the newly-released Perl 5.8.0. 1. File handles are now saved and passed in global named variables. This is the way it should be. The old way (initialize the file handles by duplicate the STDIN and assign them) was just not natural. It works in Perl 5.6.1, but not in Perl 5.8.0. The duplicated file handles are constants, which cannot be assigned new values. 2. Indents are changed from 1 tab to 4 columns, to accommodate the Perl style guide documented in perlstyle(1). This increases the code readability. 3. File operation error handlers are now using the low-precedence logical "or", instead of "||", which is recommended in perlop(1). Excessive parentheses in file operation functions are removed for this. 4. Traditional Chinese files are now named with suffix ".zh-tw" instead of ".b5". Simplified Chinese files are now named with suffix ".zh-cn" instead of ".gb". This is to accommodate RFC-3066, ISO 639:1988, ISO 3166-1 for language names. 5. PGP signatures of distribution files are added. 6. bzip2 distribution files are added. 2001-09-03 version 2.0.2 1. The bug that taking file handles as private variables and modified them, was fixed. 2001-09-01 version 2.0.1 1. The bug that resolved cache %NAMES was not global, was fixed. The resolved result can be pass between multiple files now. 2. A bug that a hyper reference in the English document was not specified as an absolute URL, was fixed. 2001-06-29 version 2.0.0 First public release. 1. Chinese and English standard header were added. 2. Getopt::Long was introduced to parse the arguments, in replace of my own argument-parsing routine. 3. File::Spec::Functions was introduced to handle the pathname. 4. Cwd was introduced to obtain the current working directory. 5. autoflush from IO::Handle was introduced, to autoflush STDOUT solely under debugging mode. 6. File::Temp was introduced to handle the temporary working file. Processing is done on temporary working files to reduce the time occupying the source and result files. 7. Compress::Zlib was used to read the compressed files. 8. rel2abs() was added to convert relative paths to absolute paths. 9. progress_bar() was added to display current status graphically. 10. res_log() was added to loop multiple files. 11. open_src() and save_res() to open source and save result. 12. POD documents was added. 13. Release notes was added. 14. Readme file was added. 15. GNU General Public License was added. 16. Installation guide was added. 17. Install.PL was added in the distribution. 2001-01-21 version 1.3.1 1. autoflush was modified to do only under debugging mode. 2. Simple header was changed standard header. 2001-01-07 version 1.3.0 1. [current/total] was added in the detailed processing messages. 2000-??-?? version 1.2.0 1. Custom parse_args() was added to parse the command line arguments. 2000-??-?? version 1.1.0 1. "--usetmp" was added to process temporary working files. 2. "--suffix" was added to alter the output suffix. 3. "--debug" was added to show detailed processing messages. 2000-12-22 version 1.0.0 First version.
