Welcome to my domain. This is an open space where I, Jeffrey Riaboy, am keeping a compendium of my projects, thoughts, news, and miscellaneous ideas. I am a self taught programmer/computer nerd that works in C++ by choice, and too many other languages due to the facts of life. I have been programming virtually my whole life and working with computers since before I can remember. They are my passion, hobby, job, first love, and have served me well, though, been a constant pain in the anatomy. I hope you can find something of interest or use here, as that is the reason I spend my time creating and organizing this content. Enjoy. ^_^

Updated:09/27/16
  • DSQL v2.0.2.2
    • Added ability via DSQL->$StrictMode variable to update MySQL strict mode
    • Added DSQL->RawQuery() function which takes just a query, and does no modification on it. I found this required due to extremely slow times on building very large queries.
    • Added DSQL->EscapeString() function which escapes a string for use in a mysql query. It has an optional parameter that adds single quotes around the result.
    • Added DSQL::PrepareInsertList() function which takes an array of names, and turns it into the following string: ['a', 'b', 'c'] => “(`a`, `b`, `c`) VALUES (?, ?, ?)”
  • DWCF v1.1.1
    • Added previous variable lookup to GetVars.VarArray.SQLLookup via %THEVAR-$VARNAME%
Section: Projects > DWCF
Updated:09/15/16
DWCF v1.1 updates
  • Added functionality:
    • GetVars.VarArray.SQLLookup:
      • Additional string parameters that have %THEVAR% are replaced with the value being checked
      • If the first item is NULL, it will be removed, and the return will include full rows ("*") of the query result set
  • Updated functionality:
    • json_encode() In RetMsg() and CallByAction() now use JSON_UNESCAPED_UNICODE
    • GetVars.VarArray.IsOptional now only triggers if it is (boolean)true
    • Added additional description specification to GetVars.VarArray.SQLLookup which says it uses the additional parameters as values to fill in the SQL Query
  • LICENSE: Now applies to 1.x instead of 1.0.x

Ping Connectivity Monitor

The following is a simple bash script to ping a different domain once a second and log the output. By default, it pings #.castledragmire.com, where # is an incrementing number starting from 0.

The script is written for Cygwin (See the PING_COMMAND variable at the top) but is very easily adaptable to Linux.

The log output is: EPOCH_TIMESTAMP DOMAIN PING_OUTPUT


#This uses Window's native ping since the Cygwin ping is sorely lacking in options
#"-n 1"=Only runs once, "-w 3000"=Timeout after 3 seconds
#The grep strings are also directly tailored for Window's native ping
PING_COMMAND=$(
	echo 'C:/Windows/System32/PING.EXE -n 1 -w 3000 $DOMAIN |';
	echo 'grep -iP "^(Request timed out|Reply from|Ping request could not find)"';
)

i=0 #The subdomain counter
STARTTIME=`date +%s.%N` #This holds the timestamp of the end of the previous loop

#Infinite loop
while true
do
	#Get the domain to run. This requires a domain that has a wildcard as a primary subdomain
	DOMAIN="$i.castledragmire.com"

	#Output the time, domain name, and ping output
	echo `date +%s` "$DOMAIN" $(eval $PING_COMMAND)

	#If less than a second has passed, sleep up to 1 second
	ENDTIME=`date +%s.%N`
	SLEEPTIME=$(echo "1 - ($ENDTIME - $STARTTIME)" | bc)
	STARTTIME=$ENDTIME
	if [ $(echo "$SLEEPTIME>0" | bc) -eq 1 ]; then
		sleep $SLEEPTIME
		STARTTIME=$(echo "$STARTTIME + $SLEEPTIME" | bc)
	fi

	#Increment the subdomain counter
	let i+=1

Booting Windows from a GPT drive with EFI

It took me days to get a Windows 7 install back up when I lost a drive with the MBR record that booted to my GPT drive. The windows booting and install processes are just REALLY finicky and temperamental. One of my largest problems was that I couldn’t find certain required files online, so the only way to acquire them was to unhook all but 1 GPT partitioned drive from the computer and install Windows to it.

Here are the files needed to boot Windows 7 x64 from a GPT drive, assuming your mother board supports EFI. The first step is creating a system partition anywhere on the drive (you may have to shrink another partition) and extract these files to that partition. This blog post has good instructions on the entire process, however, instead of using bcdboot, I recommend using “bootrec /ScanOS” followed by “bootrec /RebuildBCD”. You MAY also need a “bootrec /FixMBR”.

These files were obtained from a Windows 7 x64 Ultimate install, so it should work if your install type matches. I expect it will work for any Windows version of an x64 install.

Compiling XDebug for PHP from source in Windows

I decided to try out the PHP IDE PHPStorm by jet brains (you know, the people that made android studio) again recently but ran into a few problems. I tried it a while back and I abandoned it because I was using the browser connect method instead of xdebug and it was a major PITA. This time around, I tried xdebug and everything works much smoother and easier. However, there is a major bug with it in which single line statements inside control statements could not be stopped on in the debugger (breakpoint or stepping). This has been a problem since 2012 and was marked until very recently as unfixable. I am honestly shocked this is not a thing more cited. Do people just not use that form of formatting anymore? I find it much cleaner. Example:

if(true)
  $a=1; //This line could never be reached
So all code like this had to be changed to the following for debugging.
if(true) {
  $a=1;
}

However, in a comment by one of the developers on 2016-12-11 (just 2 months ago) he said “This turned out to be a duplicate of 1165, for which I now have cooked up a fix, which will make it into 2.5.1.”. Unfortunately, there has not yet been a release of this version, so I was forced to a compile a copy myself on Windows. This turned out to also be a major PITA. I have documented the process here. Here is the version I compiled (7.1.2 threadsafe x86)

  • To compile a php extension, you also have to compile php itself. So first download both the source and zip files for your chosen version. I used the latest version, 7.1.2 VC14 x86 Thread Safe (2017-Feb-14 23:28:41) [7.1.2 source]. The source is needed for obvious reasons. The binary is needed so we can extract some dlls not included with the source. Extract the php source root directory files to “c:\php\src.
  • You also need to grab the xdebug source [github] via “git clone git://github.com/xdebug/xdebug.git”. I used commit #62ac284bf36f7521e78d2b21492ce2899f7cc4ff #379ab7ab68d28d0af8f637aa28c7e9fab921f27a, but it actually had a bug in it which I fixed in my fork. I sent a pull request so it should hopefully be integrated soon. Clone the git repo in “c:\php\src-extensions” (it will create the “xdebug” directory inside of it)
  • You will also need visual studio 14.0 (VS 2015) [direct download] installed.
  • Once visual studio is installed, you need to open “Developer Command Prompt for VS2015”. It can be found in your start menu under “Programs\Visual Studio 2015\Visual Studio Tools”.
  • Run the following commands to get php compiled:
    cd\php\src
    buildconf --add-modules-dir=..\src-extensions
    :: You may want some different flags for the below command
    configure "--enable-snapshot-build" "--enable-debug-pack" "--without-pdo-mssql" "--enable-com-dotnet=shared" "--with-mcrypt=static" "--without-analyzer"
    :: At this point we are going to actually build php to get the phpize.bat
    :: You may receive some warnings at the end that say something to the extent of
    :: “'-9' is not recognized as an internal or external command”. You can ignore these
    nmake snap
    :: This next command will “install” php to “c:\php”.
    nmake install
  • Next we get to compile xdebug. But it requirements bison, which can be downloaded here [Direct download]. Extract bin/bison.exe and bin/m4.exe to the VC/bin directory, most likely at “C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin”.

    For some reason, the first time I did this process I needed the following files also in VC/bin directory, all found at http://gnuwin32.sourceforge.net. However, during my second run to create this tutorial, I did not need them. iconv.exe, libcharset1.dll, libiconv2.dll, libintl3.dll, mspdb110.dll, regex2.dll. And the “share” folder from the bison zip file needed to be extracted to “C:\Program Files (x86)”.
  • Some file edits in the xdebug directory:
    • Add the following line to the top of configure.js: “PHP_SECURITY_FLAGS=true;
    • If you are using the commit I mentioned, Add the following to line 471 of xdebug_code_coverage.c “zend_op *base_address = &(opa->opcodes[0]);
    • Also edit line 9 of template.rc by changing it from “#include "main/php_version.h"” to “#include "../../src/main/php_version.h"
  • And now to actually compile xdebug
    cd ..\src-extensions\xdebug
    ..\..\SDK\phpize
    configure --with-xdebug
    nmake php_xdebug.dll
    copy Release_TS\php_xdebug.dll ..\..\ext
  • Your complete php install is now located in “c:\php”. But exclude the “src” and “src-extensions” folder. It still needs a few dlls that are found in the php zip file you downloaded earlier. Extract all the dlls from that root of that file to your root php folder, but do not overwrite anything that is already there. If you wanted to compile your own version of the apache dll, you can add one of “--enable-apache2handler, --enable-apache2-2handler, --enable-apache2-4handler” to the src/configure command.
  • For some really odd reason, my version of php would always give me the following error “Packets out of order. Expected 3 received 2. Packet size=22” when trying to connect to mysql (both pdo and mysqli go through mysqlnd). So I just ended up using the php files provided through the zip file, with my newly compiled xdebug dll.
  • Definitely have to mention that the following blog post was a big help to me in figuring this all out: http://blog.benoitblanchon.fr/build-php-extension-on-windows/
