Pike 7.6.94 alpha
by Peter Bortas ＠ Pike developers forum 14 Nov '06

14 Nov '06

Pike 7.6.94 alpha can be found at: http://pike.ida.liu.se/pub/pike/alpha/7.6.94/Pike-v7.6.94.tar.gz Alpha because this will not be the release. There is text for one item in CHANGES missing and I need to fix a longstanding bug in the Unix installer. Changes since Pike 7.6.86 ---------------------------------------------------------------------- Changes in Pike: o Added conversion from Gmp.mpz objects to Gmp.bignum when cast to int. o Added timeout to Image.PS. Now kills the ghostscript process if it hasn't returned after 30s. o Added GL 1.2 and 1.3 constants. o Added possibility to set offset and stride when creating textures from memory objects in GL. o Fixed CMYK calculation in Image.Image. o Added adjusted_cmyk to Image.Image and use it when decoding with Image.PS. o Now handles more eps images internally in Image.PS without spawning ghostscript. o Added Standards.IIM that handles IPTC IPTC Information Interchange Model data in JPEG or Postscript images created with PhotoShop. o Added support for little endian TIFFs. o Added support for TIFF to Image.Dims. o Changed HTTP.Query to close connections explicitly. o Improved Parser.XML.Validating. o More paranoid checks of image headers when using Image.AVS. o Fixes to make describe_value work as usual in the free pass of the gc, so that e.g. sprintf("%O",...) behave well when called from destroy(). o Fixed truncated field names in ODBC. o Fixed masking of file positions larger than 2 GiB on 64-bit. o Fixed low-level parsing of HTTP headers to not reorder the headers. o Fixed an inverted error test in Mysql.set_charset. o Added set_charset and get_charset proxy functions to Sql.Sql. o Changed Protocols.HTTP.Query async_close() to care about the value returned by ponder_answer(). Fixes requests to broken servers that don't send proper results. o Fixed bad free_string() in exit_bytecode(). o Fixed an off-by-one crash when drawing alpha boxes all the way to the bottom of the image. o FIXME_SPECIFY: "mast: Backported multiset fixes." Other: o Improved Valgrind support. o Now checks the return code from win32 VirtualProtect. This breaks assembler optimized builds on Windows. It never worked in the first place, but used to fail silently, so this is better. This has been fixed in 7.7 by using another heap manager, but it has not been decided if it should be be backported. o Adjusted array growth policy in array_insert to double the size instead of growing with approximately one eighth of the size. This to ensure O(1) time complexity and lessen fragmentation. (This affects ADT.Sequence._insert_element and ADT.CircularList._insert_element.) o Fixed support for UnixODBC. o Made IA32 machine code compatible with Darwin IA32 ABI. Enabled machine code for Darwin. Build fixes: o Support GNU Java (GCJ) o Did away with the use of the undocumented internal MS win32 CRT functions __loctotime_t and __dtoxmode. o Fixed typo that caused the configure script to search for lots of nonapplicable include dirs on windows. o Backported new INT_TYPE_{ADD,NEG}_OVERFLOW implementation from 7.7. The old one does not work with GCC 4.1. o Fixed problem where mysql_character_set_name exists in mysql.h but not in the lib for some old mysql clients.

embedding pike
by Martin Bähr 13 Nov '06

13 Nov '06

hi, during the conference it was mentioned that pike embedding support is not done yet because there are still namespace issues? what does it take to fix those? is it anything more than renaming all the functions (prefixing them with "pike_")? greetings, martin.

<if> inside <ul> in pike site?
by Martin Bähr 11 Nov '06

11 Nov '06

hi, does anyone have a clue why an <if> inside the <ul> block on /download/index.xml never shows? <if variable='var.winstable'>works as expected</if> <ul> <li><a href="/download/pub/pike/latest-stable/"> <b>Latest stable binary version</b> (&var.stable;)</a><br/> Binaries for the most recent release are made available as we manage to produce and quality control them. Usually made for at least Linux x86, Linux ppc and Solaris sparc. For more info, read the <a href="notes/&var.stable;.xml">release notes</a>.</li> <if variable='var.winstable'>this if seems never true</if> </ul> if that would work then the simple existance of /download/currentwinstable.txt could determine wether a seperate "windows" paragraph is visible or not greetings, martin.

bugs in master with -rt
by Tobias S. Josefowitz 11 Nov '06

11 Nov '06

In master.pike, namely in "string describe_backtrace(mixed trace, void|int linewidth)" it is assumed that if (arrayp(something)) { array a = [array]something; } is a safe operation. However, if Pike is started with -rt, this provides us with neat "describe_backtrace(): Soft cast failed. Expected array, got object(is 11)" errors. The object that pretends to be an array is a backtrace_frame, at least in the cases that occured to me. PS: I forgot my password for the bugcruncher, and can't create new accounts because of a mysterious "Could not create LysKOM identity"...

invalid struct * callable?
by H. William Welliver III 10 Nov '06

10 Nov '06

I'm working on my Objective C bridge, and I'm running into a problem that doesn't make a whole lot of sense to me. I have an object that I am calling f_index() on to see if a function exists in the object, and while f_index() is returning an svalue that says it has a function in it, the callable seems to be invalid, as accessing things in it causes a segfault. I think I'm adding refs as appropriate to the program and object that the function lives in. Do I need to do anything to the function itself (which is in an object derived from a pure pike class)? push_object(pobject); push_text(funname); f_index(2); free(funname); if(Pike_sp[-1].type == PIKE_T_FUNCTION) // jackpot! { fun = Pike_sp[-1].u.efun; printf("-> get_func_by_selector(%s)\n", fun->name->str); // we segfault here add_ref(fun); pop_stack(); return fun; } else return 0; It might also be worth noting that I'm creating instances of my class using the following: struct object * pobject; pobject = clone_object(prog, 0); add_ref(pobject); object_setInstanceVariable(obj, "pobject", pobject);

Experiences with 7.7
by Bill Welliver 09 Nov '06

09 Nov '06

I'm finally getting around to trying 7.7 with some of my modules, and I've got a few observations: 1. On my install at least, pike/include/pike/precompile.pike was installed without execute permissions. 2. I've tried to compile a few modules that have C language components, and there seems to be a problem with the makefile stubs: Linking Tree /usr/local/pike/7.7.30/include/pike/smartlink: line 188: -o: command not found Linking failed: /usr/local/pike/7.7.30/include/pike/smartlink -o module.so tree.o support.o rbtree.o splay.o /usr/lib/gcc/i686-apple-darwin8/4.0.1/libgcc.a -lc /usr/lib/gcc/i686-apple-darwin8/4.0.1/libgcc.a make[1]: *** [module.so] Error 1 make: *** [all] Error 2 Any thoughts?

Subversion repository
by Marcus Comstedt (ACROSS) (Hail Ilpalazzo!) ＠ Pike (-) developers forum 05 Nov '06

And if you don't have svn 1.4, you can use svn log -rhead:26702 program.c | tail as a kind of workaround. (Since the log starts at head, the path will match the desired object in this case.)

Subversion repository
by Marcus Comstedt (ACROSS) (Hail Ilpalazzo!) ＠ Pike (-) developers forum 05 Nov '06

05 Nov '06

I now have a rather complete conversion of the Pike repository to Subversion (some more copyfrom links could be added, but otherwise everything should be ok). It includes all checkins up to and including 2006-08-29, which when I'm writing this means "everything". The dump file is in pelix:/pike/home/marcus/pike_svn.dump.gz. My suggestion is that we create an accessible repository from this somewhere, to be able to work on tooling, and to check for glitches in the conversion. Once that is ready, I'll make a new conversion for the actual switch. Which means that everything checked into the temporary repository would be discarded. I have not converted projects/ or Pike/ulpc or Pike/extra_tests, as these are not branches of the main Pike development tree. Any opinions on whether to convert some or all of these, and in that case should they be in the same repository or a different one? Some statistics: Conversion: ----------- Number of revisions: 31738 Conversion script run rime: 15h 15mins (on pelix) Dump size (uncompressed): 1.7Gb Dump size (compressed): 384Mb Test import: ------------ Dump import time: 4h 24mins (on bhelliom) Reposiory size: 421Mb (with fsfs)

pre 7.2 lib/modules/SSL.pmod ,v files
by Marcus Comstedt (ACROSS) (Hail Ilpalazzo!) ＠ Pike (-) developers forum 03 Nov '06

03 Nov '06

In trying to convert the Pike CVS repositories to Subversion, I've come across something really odd. Looking at the ,v files in /pike/data/cvsroot/Pike/7.2/lib/modules/SSL.pmod, it seems that this module was created on 1997-03-13, and included in such tags as "pike_v0_5_release_47". Yet, there is no trace of this module under /pike/data/cvsroot/Pike/0.5 (or 0.6, or 7.0), under this name or any other as far as I can tell. Where are the missing ,v files? Did somebody miss some CVSROOT/modules magic when copying the repositories from RIS?

Re: c modules and function names
by Martin Stjernholm, Roxen IS ＠ Pike developers forum 16 Oct '06

I see, it's that kind of generic glue code. An alternative is to look at the Java module which solves the same (or at least a very similar) problem.
