7zip on ESXi through p7zip – redux

Posted by jpluimers on 2019/03/12

Steps to get it working on ESXi 6.x with p7zip 16.02:

  1. Copy the output of to a place where you can reach it through http (as wget on ESXi does not understand https)
  2. Follow the script below

mkdir -p /local/bin
cd /local bin
bzip2 -d p7zip_16.02_x86_linux_bin.tar.bz2
mv p7zip_16.02/bin/7z* .
chmod 755 7z 7za 7zra

Based on much longer steps involving Windows and an older version of p7zip: 7zip on ESXi through p7zip.

IDE Fix Pack 6.4 for Delphi 2009,XE-10.2 Tokyo and 6.4.1 for Delphi 2010 and 10.3 Rio

Posted by jpluimers on 2019/03/12

On my list of things to install soon IDE Fix Pack 6.4 and 6.4.1:

Technically, there is 6.4 that works in Delphi 10.3 Rio Update 1, but it is better to install 6.4.1 as it works with 10.3 and 10.3.1:

The dependencies file looks interesting for good uses list optimisation, given that you compile with all conditional define permutations:

There is a ton of changes, of which I like the bold ones most:


  • Fixed: Packages with duplicate units may not have caused a fatal compiler error.
  • Added: Support for Delphi 10.3 Rio
  • Added: performance optimizations for faster UI rendering (D10.3)
  • Added: Infinite loop detection in TDebugger.UpdateEventLog
  • Added: Fix for TStringList.IndexOfName bug (RSP-21633)
  • Added: Fix for access violation in the Welcomepage JScript9.dll binding
  • Added: TCustomListBox.ResetContent is skipped if the handle isn’t created yet
  • Added: More STRINGCHECKS-free RTL code (2009/2010)
  • Added: More DFM Streaming optimizations
  • Added: RTL and DFM streaming patches to remove STRINGCHECKS (2009/2010)
  • Added: Removed VclFixPack OutputDebugString calls (2009)
  • Added: FillChar uses Enhanced REP MOVSB/STOSB cpu feature if available for large sizes.
  • Added: Enabled CPU LOCK string assignment optimization for local variables
  • Added: -x-Oe (experimental optimizations) and -x-cgo compiler option extension
  • Added: CodeGen: Remove of some unnecessary push/pop operations
  • Added: Expression Evaluator allows array access to pointers even if the type wasn’t declared with {$POINTERMATH ON}
  • Added: Max number of constants in a function was increased from 64K to 16M (2009-XE3)
  • Added: New compiler option extensions: -x–compileonly, -x–reslist, -x–depfile, -x–unitstats
  • Added: More performance optimization for the DCC64 compiler
  • Added: TStringBuilder.SetLength optimization [RSP-19178] (XE+)
  • Added: TStrings.GetDelimitedText optimization
  • Improved: Slight faster TStringList.IndexOfName optimization for sorted string lists.


  • Fixed: patch contained a hard coded address causing the patch to fail if the DLL’s base address was relocated. (10.3 only)
  • Fixed: TCustomListBox.ResetContent patch crashed with an access violation. (2010 only)
