[Cooker] Bug of /usr/lib/rpm/find-requires (rpm-build-4.0.4-5mdk) in finding scriptlist, caused by mdk patch
Bug of /usr/lib/rpm/find-requires (rpm-build-4.0.4-5mdk) in finding scriptlist, caused by mdk patch There's some bugs in /usr/lib/rpm/find-requires from rpm-build-4.0.4-5mdk. This bug is resulted from the patch, rpm-4.0.4-autoreq.patch.bz2, in rpm-build-4.0.4-5mdk.src.rpm. The following is the patch lines that cause this bug. # --- Grab the file manifest and classify files. filelist=`sed "s/['\"]/\\\&/g"` exelist=`echo $filelist | xargs -r file | egrep -v ":.* (commands|script) " | \ grep ":.*executable" | cut -d: -f1` -scriptlist=`echo $filelist | xargs -r file | \ +scriptlist=`echo $filelist | grep -v /usr/doc | grep -v /usr/share/doc | xargs -r file | \ egrep ":.* (commands|script) " | cut -d: -f1` liblist=`echo $filelist | xargs -r file | \ grep ":.*shared object" | cut -d : -f1` Now, first assume that the input from stdin is as follow. /usr/bin/some_script.pl /usr/doc/some_doc By the statement, filelist=`sed "s/['\"]/\\\&/g"`, the input lines passed via stdin will be turned into only one line and be kept in $filelist, $filelist == "/usr/bin/some_script.pl /usr/doc/some_doc". The bug will occur when this whole one line be grepped out by the statement, grep -v /usr/doc | grep -v /usr/share/doc, so that the /usr/bin/some_script.pl won't be detected as a script as it should be. One solution is to use the statement, xargs -r --max-args=1, to turn the $filelist into lines as follow. scriptlist=`echo $filelist | xargs -r --max-args=1 | grep -v /usr/doc | grep -v /usr/share/doc | xargs -r file | \ egrep ":.* (commands|script) " | cut -d: -f1` But from my experiment, the option, --max-args=1, will cause xargs to run very slow. Another faster solution is scriptlist=`echo " $filelist" | sed 's| /usr\(/share\)\?/doc[^ ]*||g' | xargs -r file | \ egrep ":.* (commands|script) " | cut -d: -f1` Note the leading space in " $filelist", which is important in detecting the beginning of each filename. >From my experiment, the second solution runs about 2.25 times faster than the first solution. But the first solution is less complex, and more elegant.
[Cooker] bug in php 4.0.6 about semaphores
Semaphores isn't released automatically. See http://bugs.php.net/bug.php?id=13490 This will cause some php applications to be unusable, especially, the applications that use the sem_acquire command, for example, horde/IMP ( http://www.horde.org/imp/ ). This bug doesn't occur in php 4.0.4 and php 4.1.x. As seen in, http://www.mandrakelinux.com/en/security/2002/MDKSA-2002-017.php?dis=8.0 , php in many Mandrake releases has been updated to 4.0.6, which has this bug. So, will Mandrake or Redhat plan to fix this bug by updating those old releases by php 4.1.x ? I have tried to put php 4.1.2 (from Mandrake 8.2) into my Mandrake 8.1 box, but there are many conflict dependencies that I can't resolve.
[Cooker] Bug in wget 1.5.3, the characters ";/?=&+" must retain their encoded/decoded status.
As per RFC1738 (http://www.w3.org/Addressing/rfc1738.txt, [Page 3]),
the characters ";", "/", "?", ":", "@", "=" and "&" should not be encoded
or decoded by wget, because they have a special meaning. Encoding or
decoding these characters may change the semantics of a URL.
For example, "http://abc.xyz/abc?def" and "http://abc.xyz/abc%3Fdef" are
not the same location. But when invoking the command
$ wget 'http://abc.xyz/abc%3Fdef'
, wget will change "%3F" to be "?" that will lead to the wrong location.
Also, the "+" character (not listed in RFC), should retain its
encoded/decoded status. Because it have the different meaning when
appear in a CGI query. For example,
"http://abc.xyz/abc.cgi?var1=a+b" means that var1 = "a b"
"http://abc.xyz/abc.cgi?var1=a%2Bb" means that var1 = "a+b"
The following is a patch for this bug to wget 1.5.3.

[Cooker] Re: sawmill is crashed by using gnumeric
There's some clue about this bug. If the following option of sawmill is set, then sawmill will not hang. 3.1 open gnomecc (Gnome Control Center) 3.2 select "Sawmill window manager"->"Placement" 3.3 change the "Method of selecting the position of a freshly-mapped transient window" option from "randomly" to be "best-fit", then click "OK" Also, the setting of "Method of selecting the position of a freshly-mapped window" (not transient window) option to be "randomly" will cause many application to crash sawmill. So, both options (normal and transient window) should not be set to "randomly", that will cause a serious bug.

[Cooker] sawmill is crashed by using gnumeric
Follow these step to regenerate this bug. 1. use Mandrake 7.1 2. create new user $ useradd test1 -p '' 3. login into gnome/sawmill desktop as user test1 4. open gnumeric application 5. select some texts from some X terminals to copy that texts into X clipboard 6. click menu Edit->Paste in gnumeric application 7. The X system will then hang. Sawmill will hang and eat 99% cpu time.
[Cooker] QPainter::drawImage Bug in Qt 1.44
Package: qt Version: 1.44-26mdk When I use the method, QPainter::drawImage(int x, int y, const QImage &, int sx=0, int sy=0, int sw, int sh); , the region of the QImage is incorrectly copied onto the paint device.
