GCIntegration - SpiderMonkey Redirect 1
this page is intended to explain the changes that are happening, with a focus on how they will affect gecko code that uses jsapi. at a high level, there are three issues to be aware of: interactions between the garbage collector and the cycle collector incremental garbage collection moving garbage collection the apis for gc/cc interaction and incremental gc are already in place. development of moving gc (both generational and compacting) is under way, but only in the javascript shell so far. we're still thinking about how the apis for moving gc should work. ...
...egistered in the cross-compartment wrapper map. now, on to the details... gc/cc interaction <to be done later.> incremental gc incremental gc divides gc marking into time slices. in between these slices, non-gc code is allowed to run. done naively, this technique can lead to reachable object not being marked. consider the following example. {{ svg{source: "http://people.mozilla.org/~wmccloskey/incremental1.svg", embedding: "iframe", height:"130"} }} assume object b is already marked, as in the leftmost frame, while objects a and c have not been marked yet. in the middle frame some code creates a pointer from b to c and destroys the pointer from a to c. in the last frame, a gets marked by the gc. the problem is that c is never marked even though it's reachable. this will likely lead to...
...gc. the problem is that c is never marked even though it's reachable. this will likely lead to a crash if c is accessed via b. write barriers all the schemes for preventing this sort of thing require write barriers. every time a pointer is updated, a small amount of code runs that may mark one of the objects involved in the update. this only happens if an incremental gc is in progress. spidermonkey uses a simple barrier commonly called a "snapshot at the beginning" barrier. the fundamental invariant that this barrier guarantees is that any object reachable when the incremental gc started will be marked. in addition, objects allocated during the incremental gc are marked unconditionally. at the end of the gc, any reachable object must have been newly allocated or else reachable at the beginn...

SpiderMonkey compartments
a compartment is a new concept with spidermonkey 1.8.5. compartments are used to create multiple javascript memory heaps, which avoids having one heap for all javascript objects. each compartment is a separate javascript heap. in previous versions of spidermonkey, the garbage collector would walk the entire heap of all javascript objects when garbage collection was needed. with compartments, garbage collection can run per compartment. this can result in significant performance improvements in some applications. an object in one compartment cannot touch an object in another compartment, except through a cross-compartment wrapper. compartment example the firefox browser embeds spidermonkey. in firefox 4 and above, compartments are used and all javascript objects that belong to a c...
...d to touch objects in the same compartment. this invariant is very useful for security purposes. the javascript engine enforces this requirement at a very low level. it means that a "google.com" object can never accidentally leak into an untrusted website such as "evil.com". only a special object type can cross the compartment boundaries. we call these objects cross-compartment wrappers. ...

Setting up CDT to work on SpiderMonkey
eclipse's cdt has some pretty decent features that make it an attractive environment to work in when you are interested in getting code hints, autocompletion, function, and field usage information and general ide goodness for c/c++. there is a guide for setting up cdt to work with the mozilla codebase, but it does not cover setting things up for just spidermonkey instead of the whole mozilla codebase. hence, here is a short-ish guide for doing just that. step 1 - preparing a spidermonkey build for cdt to index all code, spidermonkey has to be built with debug information. the full process of and requisites for doing so are described here. please follow those instructions up until the point of invoking configure. the initial build was in clang, so the modified build commands look like th...
...uch more detail for the entire mozilla codebase. luckily, improvements in cdt have reduced the basic process to manageable five steps: download and extract "eclipse ide for c/c++ developers" from the eclipse downloads page. start eclipse and create a workspace somewhere. select "new > makefile project with existing code" from the "file" menu. give the project a name that you like ("spidermonkey" has a nice ring to it) and use the "browser…" button to select your checkout's js/src folder for the "existing code location". choose the correct toolchain for your platform (i.e. macos x gcc on mac) and click "finish". at this point, the indexer starts running and already produces a pretty decent index of much of spidermonkey. still, there are a quite a few things that cdt does not pick up...
...tings" group tab, deactivate "use default build command". instead, change "build command" to read make -w (this is required because cdt needs detailed information about which directories make operates on, which using -w causes make to provide). change the "build location" to the build directory configured in step 1. for me, that means changing "build directory" to read ${workspace_loc:/spidermonkey/_dbg.obj}. under "behavior", make sure that "enable parallel build" is deactivated, as cdt’s indexer will freak out otherwise. remove "all" from "build (incremental build)". deactivate "clean" so that your builds do not take ages. if you want to use ccache: select "c/c++ general", then "preprocessor include patterns". under the "providers" group tab, select "cdt gcc build output parser" and...
...tring |(ccache) to the end of the "compiler command pattern" text input. start the build by selecting "build all" from the "project" menu. start the indexer by either: selecting "index > rebuild" from the project's context menu located in the project explorer window, or selecting "c/c++ index > rebuild" from the "project" menu. and that is pretty much it: large parts of spidermonkey should now be indexed. unfortunately, there are also large parts that are not properly indexed, leading to errors and warnings being shown for perfectly valid code, but i find that the parts that do work do so nicely enough to make it totally worth it. ...

Public-key cryptography - MDN Web Docs Glossary: Definitions of Web-related terms
public-key cryptography — or asymmetric cryptography — is a cryptographic system in which keys come in pairs. the transformation performed by one of the keys can only be undone with the other key. one key (the private key) is kept secret while the other is made public. when used for digital signatures, the private key is used to sign and the public key to verify. this means that anyone can verify a signature, but only the owner of the corresponding private key could have generated it. when used for encryption, the public key is used to encrypt and the private key is used to decrypt. this gives public-key encryption systems an advantage over symmetric encryption systems in that the encryption key can be made public. ...

... to the owner of the private key, but only the owner of the private key could decrypt it. however, they are typically much slower than symmetric algorithms and the size of message they can encrypt is proportional to the size of the key, so they do not scale well for long messages. as a result, it's common for an encryption system to use a symmetric algorithm to encrypt the message, then a public-key system to encrypt the symmetric key. this arrangement can confer the benefits of both systems. commonly used public-key cryptosystems are rsa (for both signing and encryption), dsa (for signing) and diffie-hellman (for key agreement). ...

NSS Key Log Format
key logs can be written by nss so that external programs can decrypt tls connections. wireshark 1.6.0 and above can use these log files to decrypt packets. you can tell wireshark where to find the key file via edit→preferences→protocols→ssl→(pre)-master-secret log filename. key logging is enabled by setting the environment variable sslkeylogfile to point to a file. note: starting with nss 3.24 (used by firefox 48 and 49 only), the sslkeylogfile approach is disabled by default for optimized builds using the makefile (those using gyp via build.sh are not affected). distributors can re-enable it at compile time though (using the nss_allow_sslkeylogfile=1 make variable) which is done for the official firefox binaries. (see bug 1188657.) notably, debian does not have this option e...

Keyword - MDN Web Docs Glossary: Definitions of Web-related terms
a keyword is a word or phrase that describes content. online keywords are used as queries for search engines or as words identifying content on websites. when you use a search engine, you use keywords to specify what you are looking for, and the search engine returns relevant webpages. for more accurate results, try more specific keywords, such as "blue mustang gto" instead of simply "mustang". webpages also use keywords in a meta tag (in the <head> section) to describe page content, so search engines can better identify and organize webpages. ...

Key - MDN Web Docs Glossary: Definitions of Web-related terms
a key is a piece of information used by a cipher for encryption and/or decryption. encrypted messages should remain secure even if everything about the cryptosystem, except for the key, is public knowledge. in symmetric-key cryptography, the same key is used for both encryption and decryption. in public-key cryptography, there exists a pair of related keys known as the public key and private key. the public key is freely available, whereas the private key is kept secret. the public key is able to encrypt messages that only the corresponding private key is able to decrypt, and vice versa. ...

Symmetric-key cryptography - MDN Web Docs Glossary: Definitions of Web-related terms
symmetric-key cryptography is a term used for cryptographic algorithms that use the same key for encryption and for decryption. the key is usually called a "symmetric key" or a "secret key". this is usually contrasted with public-key cryptography, in which keys are generated in pairs and the transformation made by one key can only be reversed using the other key. symmetric-key algorithms should be secure when used properly and are highly efficient, so they can be used to encrypt large amounts of data without having a negative effect on performance. most symmetric-key algorithms currently in use are block ciphers: this means that they encrypt data one block at a time. the size of each block is fixed and determined by the algorithm: for example aes uses 16-byte blocks. block ciphers ...

Accessible Toolkit Checklist

... toolkits, which each provide different challenges when implementing accessibility: native widget toolkits , like eclipse and wxwidgets, already have some accessibility built-in. these toolkits wrap the widgets implemented by the os with a consistent api for each platform. since the individual widgets predominately come from the operating system, they already implement standard keyboard commands and follow the operating system's visual theme. also, assistive technologies already understand native widgets so it is only necessary to implement microsoft active accessibility (msaa) api support for custom controls. however, be aware that the wrapping layer will introduce accessibility bugs, and thus you will need to test extensively and fill in the holes. you will also need to p...
