Potential bugs: * Possible incorrect results due to internal underflow, which can lead to a huge loss of accuracy while the error analysis doesn't take that into account. If the underflow occurs at the last function call (just before the MPFR_CAN_ROUND), the result should be correct (or MPFR gets into an infinite loop). TODO: check the code and the error analysis. * Possible bugs with huge precisions (> 2^30) and a 32-bit ABI, in particular undetected integer overflows. TODO: use the MPFR_ADD_PREC macro. * Possible bugs if the chosen exponent range does not allow to represent the range [1/16, 16]. * Possible infinite loop in some functions for particular cases: when the exact result is an exactly representable number or the middle of consecutive two such numbers. However for non-algebraic functions, it is believed that no such case exists, except the well-known cases like cos(0)=1, exp(0)=1, and so on, and the x^y function when y is an integer or y=1/2^k. * The mpfr_set_ld function may be quite slow if the long double type has an exponent of more than 15 bits. * mpfr_set_d may give wrong results on some non-IEEE architectures. * Error analysis for some functions may be incorrect (out-of-date due to modifications in the code?). * Possible use of non-portable feature (pre-C99) of the integer division with negative result. usr/share/doc/unzip/BUGS 0000644 00000011031 15145212666 0011060 0 ustar 00 Bogus bugs (not our fault!): --------------------------- By far THE BIGGEST source of bug reports to Info-ZIP/zip-bugs is the incorrect transfer of zipfiles (or of the UnZip executable itself). ALWAYS TRANSFER IN BINARY MODE! This includes ftp transfers and *both* ends of a Kermit connection ("set file type binary"). If your copy isn't exactly the same size as the original, you made a mistake. Another common source of errors such as "compression method 8 not sup- ported" is the existence of an old version of UnZip somewhere in your path. Make sure you're using the version you think you're using; give the full path explicitly if necessary. Executing "unzip" without any options will print a help screen, at the top of which is the UnZip version number and release date; and executing "unzip -v" without any zipfile or other options will give information about what compiler was used, the target operating system, any special UnZip options, and the date of compilation--only for version 5.11 and later, though! (Also, under Unix C shell and some Bourne shells, "which unzip" will print the path of the unzip you're actually using. Under OS/2 and MS-DOS, whch21gr.zip [on Simtel mirror sites] will do the same thing; in addi- tion, "which -a unzip" will show *all* copies of "unzip" in your path.) Bugs (real and/or imagined): --------------------------- - [OS/2 DLL] when trying to use the REXX function UzUnZipToStem to extract a file with `&' in its name, the DLL crashes (but UzUnZipToVar still works) [Daniel H, 961215] - UnZip has problems with archives bigger than 2GB; it may print "note: didn't find end-of-central-dir signature at end of central dir" (harmless) or may not be able to seek to member files [James Lemley 970107, Iris Spaniol 970206, ...] Fixed with Zip64 support in UnZip 6.0 - fix overwrite behavior: hidden/system problems?; etc. - 32-bit DOS UnZip still unable to set volume labels? - 32-bit DOS UnZip under OS/2 doesn't extract all wildcard zipfiles? [DOS box: unzip386 (ver 5.12) x:\32bit\unix\emx09a\*.zip, Hobbes 3/95] - 32-bit DOS UnZip under OS/2 doesn't set timestamp when overwriting files on HPFS partition? (go32 and pmode/w both; emx/rsx OK) [Eberhard Mattes 950726] - USE_FWRITE still causes occasional CRC errors when extracting on Pyramid? [Kevin Fritz 931102] - still NT/W95 bug with "unzip -v d:*.zip" not matching properly? [Steve S 940527] 980427: bug no longer exists, Opendir() must have been corrected by someone - when ^Z received in no-echo mode, echo is not restored (works OK if resume, however) - signal() handler disabled after first use with one of BSD/SysV? - MKS Korn shell: unzip assumes the MKS-style command-line environment options are relevant to it, but this is not the case if unzip was called by another program (e.g., from a .BAT file). A fix for this exists for Borland compilers but not for MSC, Watcom, djgpp, etc. - OS/2: for paths with one long component, the .LONGNAME EA may be saved for all components (waste of disk space): how to check?? - VMS: for extracting to other directories, only the VMS-style "-d [.foo]" format is accepted; "-d foo" should also be allowed. Long filenames are not automatically truncated to 39.39. - Novell Netware: Netware drives may clear the archive bit on extracted files under OS/2 and/or MS-DOS. UnZip always *tries* to set the archive bit, however. [pynq@uchicago, 940527] - DEC Ultrix: on long zipfiles, unzip will sometimes fail (bad CRC, not always reproducible); this is apparently due either to a hardware bug (cache mem) or OS bug (page faults?) [Igor, Jean-loup, bottom of BUGS.long] - funzip/more/decryption/no-echo bug: race condition(?) causes terminal to be "reset" to no-echo state - Macintosh (100200), Atari (020000) external file attributes not interpreted correctly (both unzip and zipinfo) - pkbug error: zipfile with incorrect csize and/or ucsize--check for end of compressed (csize) data in uncompression routines: unreduce.c: while (((outpos + outcnt) < ucsize) && (!zipeof)) { [James Birdsall, Mark, bottom of BUGS.long] - OS/2: directory EAs not restored if directory exists [Kai Uwe, KG27515@uark] (subsequent note: no way to determine which EAs are newer ==> cannot restore without user input) (update: as of UnZip 5.30, option -o forces restoring of directory EAs) - MS-DOS: Borland executables don't allow other than 80-column, 25/43/50-line screen modes (Borland bug) [Michael Stillwell] usr/share/doc/konwert-filters/en/BUGS 0000644 00000002415 15145400530 0013447 0 ustar 00 BUGS ---- `make uninstall' deletes the whole share/konwert and lib/konwert directories, even if there are some files there that are not ours. It's not easy to build the explicit list of files to be deleted. APPLE character in mac* charsets, and CH and ch characters in koi8cs are not preserved in conversion even when they are available. Also they don't respect the /1 option. Reason: they are not in Unicode. Hard links should be used when several files share the same body, differing their behaviour by their name. They are used in source files, but later they are not preserved by the installation. mkUTF8-ascii would be run once for generating both UTF8-ascii and UTF8-ascii1 if I knew how to specify one command making multiple targets in a Makefile. 512bold filter is not perfect. Some escape sequences may be emulated incorrectly. Additionally, colors changed in multiple steps or not used unnecessarily allocate some of the eight colors. fixtrsutf8 doesn't support `\-' ranges. -- __("< Marcin Kowalczyk * qrczak@knm.org.pl http://qrczak.home.ml.org/ \__/ GCS/M d- s+:-- a21 C+++>+++$ UL++>++++$ P+++ L++>++++$ E->++ ^^ W++ N+++ o?
