Foswiki tip: How to hide web at the left pane

2012-12-06T00:11:28Z

Rename the web to hide it from left pane. Say the directory is ZAdminTest, rename the folder to zAdminTest

Access it using: http://host/foswiki/bin/view/Main/ZAdminTest/WebHome

I am not sure if this works on *nix system though..

Garbage Collection

Double definition of identifiers

Since the MinGW that comes with Perl 5.16.1 cpan installation is officially weird, I upgraded the Perl installation to use MinGW 4.6.2.

But this comes with it's own problem, today, I tried to install DB_File and I encounter this error during make process:

> dmake
C:\CPANTE~1\PERL51~1.1\site\lib\auto\MINGW-~1.2\bin\gcc.exe -c  -IC:\CPANTesters\archives\db-4.8.30-mingw32\include\db  -DNDEBUG -DWIN32 -D_CONSOLE -DNO_STRICT-DPERL_TEXTMODE_SCRIPTS -DUSE_SITECUSTOMIZE -DPERL_IMPLICIT_CONTEXT -DPERL_IMPLICIT_SYS -DUSE_PERLIO -D_USE_32BIT_TIME_T -DHASATTRIBUTE -fno-strict-aliasing -mms-bitfields -O2           -DVERSION=\"1.827\"   -DXS_VERSION=\"1.827\"  "-IC:\CPANTesters\Perl5.16.1\lib\CORE"  -D_NOT_CORE  -DmDB_Prefix_t=size_t -DmDB_Hash_t=u_int32_t version.c
In file included from C:\CPANTesters\archives\db-4.8.30-mingw32\include\db/db.h:30:0,
                 from version.c:30:
c:\cpante~1\perl51~1.1\site\lib\auto\mingw-~1.2\bin\../lib/gcc/mingw32/4.6.2/../../../../include/pthread.h:612:3: error: expected identifier before numeric constant
dmake.exe:  Error code 129, while making 'version.o'

This is the offending code on MinGW-4.6.2/include/pthread.h.

enum {
	PTHREAD_CREATE_JOINABLE       = 0,
	...
};

After a long winded troubleshooting session & research, I found that PTHREAD_CREATE_JOINABLE has already defined in Perl\lib\CORE\thread.h. Disabling the offending line in MinGW-4.6.2/include/pthread.h fixes the problem.

~~But I encounter a new dilemma, for future usage, should I disable PTHREAD_CREATE_JOINABLE definition at MinGW-4.6.2/include/pthread.h or Perl\lib\CORE\thread.h?~~

~~I am really tempted to edit Perl\lib\CORE\thread.h instead of MinGW 4.6.2 since I use MinGW to make other binaries.~~

~~Any suggestion?~~

Touching Perl\lib\CORE\thread.h will bork the test, need to edit MinGW-4.6.2/include/pthread.h instead before testing.

Skype is borking Foswiki on a stick

2012-09-23T06:13:22Z

Lately my foswiki on the stick has been throwing this error whenever I try launch it, looking into C:\xampp\apache\logs\error.log, this comes up:

(OS 10048)Only one usage of each socket address (protocol/network address/port) is normally permitted. : make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs

Skipping the long winded troubleshooting narrative, I remember that I just upgraded Skype to 5.10.0.116. After shutting down Skype, I am able to bring Foswiki up again.

It's interesting that Skype uses port 80 to do it's business.

Compiled db-4.8.30 for MinGW64

2012-09-21T00:02:09Z

Installing DB_File has been a pain, especially when binaries for db is no where to be found and instruction is rare. After spending a lot of time going through Google search result, I finally found this good instruction.

The binaries are available here.

Installing IO::All on Win32 (no Cygwin)

2011-06-05T22:43:12Z

IO:All 0.41 can be installed successfully on Win32 (no Cygwin), if the test fails and spews something like this:

# Failed test at t/file_spec.t line 28.
# got: '33'
# expected: '34'
# Looks like you failed 1 test of 27.
t/file_spec.t ........
Dubious, test returned 1 (wstat 256, 0x100)
Failed 1/27 subtests

The alternatives:

fix your %PATH% of more than one partition character (';')
fix t/file_spec.t
