Lasse Collin 389d418445 Add missing public domain notice to lzmadec_w32res.rc. 2010-10-09 12:57:25 +03:00
Lasse Collin 6389c773a4 Windows: Update common_w32res.rc. 2010-10-09 12:52:12 +03:00
Lasse Collin d3cd7abe85 Use LZMA_VERSION_STRING instead of PACKAGE_VERSION.
Those are the same thing, and the former makes it a bit
easier to build the code with other build systems, because
one doesn't need to update the version number into custom
config.h.

This change affects only lzmainfo. Other tools were already
using LZMA_VERSION_STRING.

Lasse Collin b1c7368f95 Build: Add options to disable individual command line tools. 2010-10-08 15:25:45 +03:00
Lasse Collin f9907503f8 Build: Remove the static/dynamic tricks.
Most distros want xz linked against shared liblzma, so
it doesn't help much to require --enable-dynamic for that.
Those who want to avoid PIC on x86-32 to get better
performance, can still do it e.g. by using --disable-shared
to compile xz and then another pass to compile shared liblzma.

Part of these static/dynamic tricks were needed for Windows
in the past. Nowadays we rely on GCC and binutils to do the
right thing with auto-import. If the Autotooled build system
needs to support some other toolchain on Windows in the future,
this may need some rethinking.

Thanks to Jonathan Nieder.

Lasse Collin 61ae593661 liblzma: Small fixes to comments in the API headers. 2010-10-02 11:38:20 +03:00
Lasse Collin 31575a449a Fix accomodate -> accommodate on the xz man page. 2010-09-28 01:17:14 +03:00
Lasse Collin cec0ddc8ec Major man page updates.
Lots of content was updated on the xz man page.

Technical improvements:
  - Start a new sentence on a new line.
  - Use fairly short lines.
  - Use constant-width font for examples (where supported).
  - Some minor cleanups.

Thanks to Jonathan Nieder for some language fixes.

Lasse Collin 075257ab04 Fix the preset -3e.
depth=0 was missing.

Lasse Collin a8760203f9 xz: Add a comment to translators about "literal context bits". 2010-09-10 14:09:33 +03:00
Lasse Collin bb0b1004f8 xz: Multiple fixes.
The code assumed that printing numbers with thousand separators
and decimal points would always produce only US-ASCII characters.
This was used for buffer sizes (with snprintf(), no overflows)
and aligning columns of the progress indicator and --list. That
assumption was wrong (e.g. LC_ALL=fi_FI.UTF-8 with glibc), so
multibyte character support was added in this commit. The old
way is used if the operating system doesn't have enough multibyte
support (e.g. lacks wcwidth()).

The sizes of buffers were increased to accomodate multibyte
characters. I don't know how big they should be exactly, but
they aren't used for anything critical, so it's not too bad.
If they still aren't big enough, I hopefully get a bug report.
snprintf() takes care of avoiding buffer overflows.

Some static buffers were replaced with buffers allocated on
stack. double_to_str() was removed. uint64_to_str() and
uint64_to_nicestr() now share the static buffer and test
for thousand separator support.

Integrity check names "None" and "Unknown-N" (2 <= N <= 15)
were marked to be translated. I had forgot these, plus they
wouldn't have worked correctly anyway before this commit,
because printing tables with multibyte strings didn't work.

Thanks to Marek Černocký for reporting the bug about
misaligned table columns in --list output.

Lasse Collin 41bc9956eb xz: Add a note to translators. 2010-09-07 12:31:40 +03:00
Lasse Collin 77a7746616 Fix use of N_() and ngettext().
I had somehow thought that N_() is usually used
as shorthand for ngettext().

This also fixes a missing \n from a call to ngettext().

Lasse Collin c46afd6edc xz: Use lzma_lzma_preset() to initialize the options structure. 2010-09-04 23:12:20 +03:00
Lasse Collin 8fd3ac046d Don't set lc=4 with --extreme.
This should reduce the cases where --extreme makes
compression worse. On the other hand, some other
files may now benefit slightly less from --extreme.

Lasse Collin 474bac0c33 xz: Minor improvements to --help and --long-help. 2010-09-04 22:10:32 +03:00

Lasse Collin b4b1cbcb53 Tweak the compression presets -0 .. -5.
"Extreme" mode might need some further tweaking still.
Docs were not updated yet.

Lasse Collin 77fe5954cd liblzma: Adjust default depth calculation for HC3 and HC4.
It was 8 + nice_len / 4, now it is 4 + nice_len / 4.
This allows faster settings at lower nice_len values,
even though it seems that I won't use automatic depth
calcuation with HC3 and HC4 in the presets.
2010-09-03 12:28:41 +03:00
Lasse Collin fce69059cf xz: Make --help two lines shorter.
At least for now, the --help option doesn't list any
options that take arguments, so "Mandatory arguments to..."
can be omitted.
2010-09-03 11:11:25 +03:00
Lasse Collin a848e47ced xz: Make setting a preset override a custom filter chain.
This is more logical behavior than ignoring preset level
options once a custom filter chain has been specified.

Lasse Collin b3ff7ba044 xz: Always warn if adjusting dictionary size due to memlimit. 2010-09-02 19:09:57 +03:00
Lasse Collin 792331bdee Disable the memory usage limiter by default.
For several people, the limiter causes bigger problems that
it solves, so it is better to have it disabled by default.
Those who want to have a limiter by default need to enable
it via the environment variable XZ_DEFAULTS.

Support for environment variable XZ_DEFAULTS was added. It is
parsed before XZ_OPT and technically identical with it. The
intended uses differ quite a bit though; see the man page.

The memory usage limit can now be set separately for
compression and decompression using --memlimit-compress and
--memlimit-decompress. To set both at once, -M or --memlimit
can be used. --memory was retained as a legacy alias for
--memlimit for backwards compatibility.

The semantics of --info-memory were changed in backwards
incompatible way. Compatibility wasn't meaningful due to
changes in the memory usage limiter functionality.

The memory usage limiter info is no longer shown at the
bottom of xz --long -help.

The memory usage limiter support for removed completely from xzdec.

xz's man page was updated to match the above changes. Various
unrelated fixes were also made to the man page.

Lasse Collin d8b41eedce Fix compiling with -Werror. 2010-06-02 23:13:55 +03:00
Lasse Collin b5fbab6123 Silence a bogus Valgrind warning.
When using -O2 with GCC, it liked to swap two comparisons
in one "if" statement. It's otherwise fine except that
the latter part, which is seemingly never executed, got
executed (nothing wrong with that) and then triggered
warning in Valgrind about conditional jump depending on
uninitialized variable. A few people find this annoying
so do things a bit differently to avoid the warning.

Lasse Collin e89d987056 Adjust SA_RESTART workaround.
I want to get a bug report if something else than
DJGPP lacks SA_RESTART.

Lasse Collin 44d70cb154 Take Cygwin into account in some #if lines.
This change is no-op, but good to have just in case
for the future.

Jonathan Nieder 01a414eaf4 Use my_min() instead of MIN() in src/xz/list.c

2010-05-27 13:30:48 +03:00
Lasse Collin 920a69a8d8 Rename MIN() and MAX() to my_min() and my_max().
This should avoid some minor portability issues.
