Python binding for NSS
project information
python-nss is a
python binding for nss (network security services) and nspr (netscape portable runtime).
...
python also provides an abstraction of common operating system services but because nss and nspr are tightly bound
python-nss exposes elements of nspr.
... design goals nss and nspr are c language api's which
python-nss "wraps" and exposes to
python programs.

Introduction to the server side - Learn web development
server-side code can be written in any number of programming languages — examples of popular server-side web languages include php,
python, ruby, c#, and nodejs(javascript).
... in contrast, you would almost never consider writing the server-side component of a web app without a framework — implementing a vital feature like an http server is really hard to do from scratch in say
python, but
python web frameworks like django provide one out of the box, along with other very useful tools.

Creating reftest-based unit tests
running reftest-based unit tests note: mach is a
python2 script.
... if your use
python3 as default you must edit the first line of mach.
Gmake vs. Pymake
for example, if using the default objdir, you might type in the root of your source tree: mkdir obj-i686-pc-mingw32; cd obj-i686-pc-mingw32;
python ../build/pymake/make.py -f ../client.mk.
... note that typing "
python build/pymake/make.py -f client.mk" does not trigger a relative configure.
Simple Sunbird build
# get the source hg clone http://hg.mozilla.org/comm-central/ cd comm-central
python client.py checkout # setup a basic .mozconfig file echo 'ac_add_options --enable-application=calendar' > .mozconfig # let's build sunbird...
...how to build again later in your comm-central directory, run these commands: # get the latest source
python client.py checkout then just re-run the "make -f client.mk" command above.
Eclipse CDT
one suggested configuration for building gdb is '--prefix="$home" --disable-debug --with-
python=/usr' (create an optimized build with support for
python (so that you can use
python to much better control when you break etc.), and install it in $home/bin).
... on mac, create a script called something like open-my-workspace.py, give it the following contents, replacing the bold paths as appropriate, and make it executable (chmod a+x open-my-workspace.py): #!/usr/bin/env
python import os, subprocess eclipse_app_path = "path/to/eclipse.app/contents/macos/eclipse" workspace_path = os.path.join(os.environ['home'], "home/relative/path/to/the/directory/of/the/workspace/you/want/to/open") subprocess.popen([eclipse_app_path, "-data", workspace_path]) # uncomment the following line to automatically close the terminal window # that opens if you run this script by double clicking...

Localizing with Mercurial
run the following commands in the command line to get the source en-us files for any combination of firefox, seamonkey, thunderbird: hg clone https://hg.mozilla.org/comm-central/ cd comm-central
python client.py checkout the first command will create a clone of the comm-central repository.
... to update your working copy of comm-central, go to your comm-central directory and run:
python client.py checkout this will both get new changesets from comm-central, mozilla-central and the other appropriate locations and apply those changes in your working copy.
Localization prerequisites
tools a recent posix shell
python 2.5 or newer.
...now continue the scheme for
python and perl, and try zip -h, too.
Investigating leaks using DMD heap scan mode
the command to invoke this looks like this:
python $heapgraph/find_roots.py $cclog $winaddr this may take a few seconds.
... after that is done, we can finally find out which objects (possibly) point to other objects, using the block_analyzer script:
python $srcdir/memory/replace/dmd/block_analyzer.py dmd-$pid.log.gz $leakaddr this will look through every block of memory in the log, and give some basic information about any block of memory that (possibly) contains a pointer to that object.

Running Parsemark
within js/src/tests, run
python parsemark.py -h to see help documentation.
...a typical run can be done like so: cd js/src/tests
python parsemark.py /path/to/baseline/js /path/to/parse-tests-dir/ -q > /tmp/baseline.json
python parsemark.py /path/to/current/js /path/to/parse-tests-dir/ -q > /tmp/current.json

compare-locales

Setting up an update server
an easy way to do this is with
python.
...this is the
python2 command:
python -m simplehttpserver 8000 or, this is the
python3 command:
python3 -m http.server 8000 if you aren't sure that you started the server correctly, try using a web browser to navigate to http://127.0.0.1:8000/update.xml and make sure that you get the xml file you created earlier.
Using the Mozilla symbol server
symchk: failed files = 4 symchk: passed + ignored files = 179 downloading symbols on linux / mac os x if you are on linux and running gdb 7.9 or newer, you can use this gdb
python script to automatically fetch symbols.
...if you want to reload symbols, you can try: nosharedlibrary sharedlibrary lib on older gdb and mac os x there is a
python script to download symbols from the mozilla symbol server for gdb, shark and other software that uses symbols.
Grammar and types - JavaScript
basics javascript borrows most of its syntax from java, c, and c++, but it has also been influenced by awk, perl, and
python.
...(this is similar to string interpolation features in perl,
python, and more.) optionally, a tag can be added to allow the string construction to be customized, avoiding injection attacks, or constructing higher-level data structures from string contents.

in the same way, if you want to say, program some 3d graphics, it is a lot easier to do it using an api written in a higher-level language such as javascript or
