-ijar: A tool for generating interface .jars from normal .jars
-=============================================================
-
-Alan Donovan, 26 May 2007.
-
-Rationale:
-
-  In order to improve the speed of compilation of Java programs in
-  Bazel, the output of build steps is cached.
-
-  This works very nicely for C++ compilation: a compilation unit
-  includes a .cc source file and typically dozens of header files.
-  Header files change relatively infrequently, so the need for a
-  rebuild is usually driven by a change in the .cc file.  Even after
-  syncing a slightly newer version of the tree and doing a rebuild,
-  many hits in the cache are still observed.
-
-  In Java, by contrast, a compilation unit involves a set of .java
-  source files, plus a set of .jar files containing already-compiled
-  JVM .class files.  Class files serve a dual purpose: from the JVM's
-  perspective, they are containers of executable code, but from the
-  compiler's perspective, they are interface definitions.  The problem
-  here is that .jar files are very much more sensitive to change than
-  C++ header files, so even a change that is insignificant to the
-  compiler (such as the addition of a print statement to a method in a
-  prerequisite class) will cause the jar to change, and any code that
-  depends on this jar's interface will be recompiled unnecessarily.
-
-  The purpose of ijar is to produce, from a .jar file, a much smaller,
-  simpler .jar file containing only the parts that are significant for
-  the purposes of compilation.  In other words, an interface .jar
-  file.  By changing ones compilation dependencies to be the interface
-  jar files, unnecessary recompilation is avoided when upstream
-  changes don't affect the interface.
-
-Details:
-
-  ijar is a tool that reads a .jar file and emits a .jar file
-  containing only the parts that are relevant to Java compilation.
-  For example, it throws away:
-
-  - Files whose name does not end in ".class".
-  - All executable method code.
-  - All private methods and fields.
-  - All constants and attributes except the minimal set necessary to
-    describe the class interface.
-  - All debugging information
-    (LineNumberTable, SourceFile, LocalVariableTables attributes).
-
-  It also sets to zero the file modification times in the index of the
-  .jar file.
-
-Implementation:
-
-  ijar is implemented in C++, and runs very quickly.  For example
-  (when optimized) it takes only 530ms to process a 42MB
-  .jar file containing 5878 classe, resulting in an interface .jar
-  file of only 11.4MB in size.  For more usual .jar sizes of a few
-  megabytes, a runtime of 50ms is typical.
-
-  The implementation strategy is to mmap both the input jar and the
-  newly-created _interface.jar, and to scan through the former and
-  emit the latter in a single pass. There are a couple of locations
-  where some kind of "backpatching" is required:
-
-  - in the .zip file format, for each file, the size field precedes
-    the data.  We emit a zero but note its location, generate and emit
-    the stripped classfile, then poke the correct size into the
-    location.
-
-  - for JVM .class files, the header (including the constant table)
-    precedes the body, but cannot be emitted before it because it's
-    not until we emit the body that we know which constants are
-    referenced and which are garbage.  So we emit the body into a
-    temporary buffer, then emit the header to the output jar, followed
-    by the contents of the temp buffer.
-
-  Also note that the zip file format has unnecessary duplication of
-  the index metadata: it has header+data for each file, then another
-  set of (similar) headers at the end.  Rather than save the metadata
-  explicitly in some datastructure, we just record the addresses of
-  the already-emitted zip metadata entries in the output file, and
-  then read from there as necessary.
-
-Notes:
-
-  This code has no dependency except on the STL and on zlib.
-
-  Almost all of the getX/putX/ReadX/WriteX functions in the code
-  advance their first argument pointer, which is passed by reference.
-
-  It's tempting to discard package-private classes and class members.
-  However, this would be incorrect because they are a necessary part
-  of the package interface, as a Java package is often compiled in
-  multiple stages.  For example: in Bazel, both java tests and java
-  code inhabit the same Java package but are compiled separately.
-
-Assumptions:
-
-  We assume that jar files are uncompressed v1.0 zip files (created
-  with 'jar c0f') with a zero general_purpose_bit_flag.
-
-  We assume that javap/javac don't need the correct CRC checksums in
-  the .jar file.
-
-  We assume that it's better simply to abort in the face of unknown
-  input than to risk leaving out something important from the output
-  (although in the case of annotations, it should be safe to ignore
-  ones we don't understand).
-
-TODO:
-  Maybe: ensure a canonical sort order is used for every list (jar
-  entries, class members, attributes, etc.)  This isn't essential
-  because we can assume the compiler is deterministic and the order in
-  the source files changes little.  Also, it would require two passes. :(
-
-  Maybe: delete dynamically-allocated memory.
-
-  Add (a lot) more tests.  Include a test of idempotency.
