[Ubuntu-x-swat] [Bug 393503] [NEW] Performance-related changes made by Debian to libxcb 1.1
Public bug reported: Debian has recently made a 1.1-1.2 release of libxcb to stable. Since Hardy derived from the same version and is LTS, I thought these changes might be worth also applying to Hardy. The changelog for 1.1-1.2 reads: libxcb (1.1-1.2) stable; urgency=low * Non-maintainer upload to fix important performance issues (closes: #487635). * Fix some fd leaks in _xcb_open_*() * Increase libxcb buffer size to 16k from 4k * Disable Nagle on TCP socket -- Julien Cristau jcris...@debian.org Wed, 27 May 2009 20:06:47 +0200 If you do make an SRU containing these changes, please also ensure that the version in ia32-libs is updated. ** Affects: libxcb (Ubuntu) Importance: Undecided Assignee: Timo Aaltonen (tjaalton) Status: New -- Performance-related changes made by Debian to libxcb 1.1 https://bugs.launchpad.net/bugs/393503 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libxcb in ubuntu. ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

[Ubuntu-x-swat] [Bug 393509] [NEW] Applications that use libxcb 1.1 cannot open more than 1024 files
Public bug reported: Hi, We have some internal 32-bit applications that end up with a lot of files open. If they in turn call a program that links with libxcb, more often than not, that program segfaults. This has been determined to be because libxcb uses select() and the man page for select() says this: An fd_set is a fixed size buffer. Executing FD_CLR() or FD_SET() with a value of fd that is negative or is equal to or larger than FD_SETSIZE will result in undefined behavior. Moreover, POSIX requires fd to be a valid file descriptor. Later versions of libxcb address this by using poll() I'm attaching the patch that we are using internally against libxcb 1.1-1.1 If you make this SRU, please also ensure that the 32-bit version in ia32-libs gets updated. ** Affects: libxcb (Ubuntu) Importance: Undecided Status: New -- Applications that use libxcb 1.1 cannot open more than 1024 files https://bugs.launchpad.net/bugs/393509 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libxcb in ubuntu. ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
