Although on special occasions and/or ceremonies the xoloitzcuintli was eaten by the olmecah, Toltecah –and later the Mexicah – it was during and after the Spanish monarchy’s sponsored invasion, when Spain’s genetic waste and their analogous symbiotic parasite rats infested Mexico-Tenochtitlan and devoured the xoloitzcuintzintin with such voracity the unique canine specimens were almost driven into extinction. Alarmed at the Spaniards’ rapacious craving for xoloitzcuintzintin meat, a number of xoloitzcuintli specimens either fled to or where surreptitiously taken to Mixtecapan –nowdays Oaxaca– defining a do-or-die inflection point to spare the xoloitzcuintli from total annihilation by the voracious alien Tzitzimimeh –embodied in the Spanish fanatical Christian terrorists. Conniving and co-opting military, logistic, and tactical support from jaundiced subjugated native ‘city-states’, Spanish scum gloated3 over their divide-and-conquer strategy to achieve ensuing destruction and pillage of the Mexicah’s highly sophisticated and cultured eponymous Altepetl (’city state’). Fact is, occupier Iberian State (IS) terrorist cliques even have appropriated ‘Mexican‘ – transliterated into their Spanish dialect by concatenating suffixes ‘-o‘ or ‘-a‘ for male or female, respectively – as their ‘ethnic‘ moniker thus besmirching the legitimate ancient and surviving Mexicah / Nahua ethnic genotype with current Iberian unabated corruption, lawlessness, plundering, and low intensity environmental, economic, cultural, and ethnic genocide, all of which had been gradually building up since 1521.
Hmmm, pardon my memory focus lapse, I meant to begin with…
Realizing that the PHP developer of pthreads has, using the proverbial expression, ‘thrown his puppy…er, baby, out with the bathwater‘5, I had second thoughts about writing this post. I mean, to build the latest PHP 7.3.9̶ 10 the ‘Debian way‘ for Metztli Reiser4 / Debian Buster BPs was the only topic I was gonna annotate as my reference post. Notwithstanding, online I read of people literally ‘twerking‘ with phpize to build pthreads support for their PHP ZTS build and I thought: the ‘Debian way‘ really simplifies the procedure. What I mean is, after we hack the Debian packaging for PHP into producing a KrakJoe6 pthreads extension, all we have to do is install relevant DEB package and…that’s it! to enable the much sought after feature. I am not an expert on Toltecayotl –much less pthreads – so we will recycle a couple small test ‘pthreaded‘ programs, execute them, and that –hopefully– will be a measure of our success
NOTE: PHP 7.3.11 Fixes CVE-2019-11043, thus upgraded resources in this post. All references to PHP 7.3.10 apply equally to PHP 7.3.11 –including the patches I create here. (10-27-2019)
Build PHP 7.3.10 the ‘Debian way’ on Metztli Reiser4 / Debian 10 Buster
We fetch PHP 7.3.10 and corresponding asc extension file to verify source integrity:
For our Debian Buster backports we will be using Debian Sid packaging for PHP 7.3.10-1; maintainer has caught up!
Subsequently, create build directory and untar PHP 7.3.10 and Debian packaging for 7.3.10-1 into the former untarred source:
For Debian 10 Buster we will be installing the same package names as in prior relevant blog post for Debian Stretch – thus satisfying our PHP 7.3.10 build requirements. Please review if you want to install the latest MariaDB available from MariaDB.org repositories, instead of Debian’s:
The list above is derived from debian/control file in Debian packaging for php7.3_7.3.10-1 on AMD64 and we only get a couple of ‘Notes‘:
Note, selecting ‘apache2-dev’ instead of ‘dh-apache2′
Note, selecting ‘libargon2-dev’ instead of ‘libargon2-0-dev’
We change directory to PHP 7.3.10 source, if we are not already there yet:
create a link to debian/patches:
and apply the patches with quilt:
all patches should apply flawlessly –as seen in the snapshot taken at the end of the quilt procedure:
NOTE: If we are leveraging Debian packaging for php7.3_7.3.10-1.debian.tar.xz to build upstream PHP 7.3.11, we need to upgrade the version; otherwise, the generated packages will have lower incorrect version. Thus we need to correct the debian/changelog with:
We may begin our PHP 7.3.10 build with the following directive:
From relevant man page, where X:= Number of jobs allowed to be run simultaneously, number of jobs matching the number of online processors if auto is specified (since dpkg 1.17.10), or unlimited number if jobs is not specified, equivalent to the make(1) option of the same name (since dpkg 1.14.7, long option since dpkg 1.18.8).
After thirty(30) to forty-five(45) minutes the Debian packaging for php7.3_7.3.10-1.1 build ends:
…and corresponding SHA256SUMs:
Build PHP 7.3.10 ZTS and pthreads the ‘Debian way’ on Metztli Reiser4
We go back a couple of directories – to our initial location where we downloaded relevant PHP resources – and create our build directory for PHP 7.3.10 ZTS and pthreads:
As before, we untar PHP 7.3.10 source into the above directory we have just created:
Listing PHP 7.3.10 source content:
we change into the PHP 7.3.10 source directory:
As I am intending to make a patch, I will initiate with git:
and make Ynic cecni, i.e., First, commit:
I list ext directory contents and change into it:
then clone krakjoe pthreads at that location:
By listing hidden git resources in newly cloned pthreads directory, I locate resource targets to remove:
and remove those:
then I locate php_pthreads.h which I will edit in-place subsequently using sed:
as I am going to operate on a line range, excluding 30 but including 51, where I will replace all < less than and > greater than operator symbols by double quotes:
We can see the before and after the sed operation differences on referenced lines:
fact is our build will halt if those modifications are not done.
I will now be creating a metztli-ext-pthreads.patch that I will subsequently integrate into Debian packaging for php7.3_7.3.10-1 at debian/patches/metztli/metztli-ext-pthreads.patch.
First I go back from current directory ext/ to PHP 7.3.10 source root directory:
and create an Ome, i.e., Second, commit for pthreads source addition:
and create my patch:
Modifying and simultaneously creating a ZTS and pthreads patch for Debian packaging for php7.3_7.3.10-1 itself.
Observing the image above, pthreads arguably was in the discipline of Toltecayotl, taught by the Toltecah masters –tlamemeh, i.e., carriers, of the xiuhcohuanahualli7 which enabled Tlalnepantla [’mesoamerica‘] civilization to flourish for many multiple millennia.
Picking up where I left off, I was inside source directory for PHP 7.3.10 with pthreads, and change one directory back:
I have Debian packaging php7.3_7.3.10-1.debian.tar.xz which when untarred will create a single debian directory were I will be modifying and/or adding resources so that it can hack out a PHP 7.3.10-1.1 ZTS with pthreads version of Debian packages.
Again, I will be creating a patch simultaneously as I modify and/or add resources:
First file we will be modifying in-place is control –remember we are inside the debian directory. At line number 316, we will be adding following directives specifying creation of a pthreads module:
IMPORTANT: You need to observe the debian formatting of control file and the lines immediately below the string text ‘Description’ should have a leading blank character. Observe the ensuing snapshot.
We will use sed to replace every string of the form php7.3 by php7.3-zts:
We can see the very first line instance modification in the partial side by side comparison snapshot:
Now, we will concatenate the pthreads LICENSE contents into existing debian copyright file, respecting its format, by inserting a blank line followed by the header: License: pthreads
then concatenate the LICENSE file, found in the phthreads directory we cloned and worked on previously:
Analyzing the result by opening our modified copyright file with xvi text editor we want to remove those extraneous characters represented as ‘^M‘ which were embedded in pthreads LICENSE. We will use sed and to specify the extraneous characters, I will input CTRLv followed by CTRLm
Please see raw concatenated copyright instance to our left and on the right the copyright file operated on by sed:
We continue by integrating our previously created patch metztli-ext-pthreads.patch into debian patches structure. First we list the contents of patches directory:
Then I create a metztli directory and copy metztli-ext-pthreads.patch into it:
finally I include a reference to my patch into the series file which is used by quilt patching utility.
Now I will create a rules.d/pthreads.mk configuration file using xvi text editor:
where the content below will be inserted:
We save our file and exit xvi
Finally, we are going to hack debian rules file to modify our cli php∙ini file by inserting the proper pthreads directive, CHINGON!
Thus I instantiate a variable, CHINGON, by assigning it the following string of characters to be interpreted by sed:
at line 937 insert ;Metztli IT added required cli directive: (php∙ini comments begin with leading ; semicolon);
then add new line which begins with extension=pthreads and end line with backslash followed by blank character
and use sed to insert $CHINGON value at line 527 in debian rules file (yes, sed will edit in-place but makes a rules.back -up:
And I verify modification in debian rules file by opening it with xvi and editing the inserted text by moving it away from the left edge and aligning, and matching format, with the existing debian code, as below:
I save modifications to debian rules file and exit xvi.
Subsequently, I replace only the very first occurrence of php7∙3 with php7∙3-zts in debian changelog:
and I am ready to make a patch against Debian packaging for php7.3_7.3.10-1 ZTS and pthreads:
Having created our Debian packaging for php7.3_7.3.10-1.x, we exit debian directory by going back to our initial directory location –where we downloaded our PHP resources ; our objective is to build actual PHP with ZTS and pthreads hack the ‘Debian way’, hence I create appropriately named directory:
Again, I untar PHP 7.3.10 source into our newly created directory:
and untar official debian packaging for php7.3_7.3.10-1 into the PHP 7.3.10 source directory:
I verify that debian directory was untarred at the target location and proceed to change into PHP source directory
I check for the existence of pthreads by listing ext/ directory contents… of course, pthreads is not there.
And test application of my ZTS and pthreads patch into debian packaging for php7.3_7.3.10-1:
and subsequently apply the patch:
I make a symbolic link to debian/patches directory:
and follow with a quilt operation to push…er, apply all patches listed in series file:
we notice that the last patch applied by quilt was our very first metztli-ext-pthreads.patch which adds pthreads source into ext/ directory. We may wish to verify ext/ for the existence of pthreads.
Although not strictly necessary, I do label my builds minimally as follows:
BUT: If we are leveraging Debian packaging for php7.3_7.3.10-1.debian.tar.xz to build upstream PHP 7.3.11 ZTS with pthreads, we need to upgrade the version; otherwise, the generated packages will have lower incorrect version. Thus I need to correct the debian/changelog with:
Both 93 and 94 generate a warning because metztli is not an official Debian distribution.
After I dismiss it a text editor opens debian/changelog file for my irreverent annotations. Subsequently, I save my modifications/additions, the editor closes changelog and I am returned to my shell.
The objective of a subset of our modifications was to enable ZTS build, accordingly I type:
I begin the build procedure, as before, with our tlilxochitl, i.e., ‘vanilla‘, PHP 7.3.10 build:
where X implies previous meaning, i.e., Number of jobs allowed to be run simultaneously, number of jobs matching the number of online processors if auto is specified (since dpkg 1.17.10), or unlimited number if jobs is not specified, equivalent to the make(1) option of the same name (since dpkg 1.14.7, long option since dpkg 1.18.8).
Likewise,after thirty(30) to fifty(50) minutes with 6 cores assigned, i.e., -j6, PHP 7.3.10 ZTS and pthreads build procedure ends, generating DEB packages the ‘Debian way’:
NOTE: this build is more recent than the one whose sample output I showed in the cover. Additionally, you need php-common from your favourite debian repository in addition to the first six(6) packages below to try out pthreaded programs.
Remember: pthreads v3 is restricted to operating in CLI only: I have spent many years trying to explain that threads in a web server just don’t make sense, after 1,111 commits to pthreads I have realised that, my advice is going unheeded. ~krakjoe
Although due diligence was exercised, what/whoever entity who decides or is inspired to follow the procedure(s) shown as proof-of-concept (PoC) and/or downloads Metztli Reiser4 for AMD64 -generated PHP 7.3.10/11 ZTS and pthreads does so willingly knowing that I and/or Metztli IT DO NOT OFFER ANY GUARANTEE OR EXTEND ANY WARRANTY ON THESE RESOURCES. Further, I and/or Metztli IT reserve the right to modify the post with corrections and/or additions and/or even delete it without advanced notice.
