* Integrated filesystem operation abstraction code into filesystem.cpp
* Modified filesystem unit tests to be more platform agnostic
* Added append mode for PlatformFile
* Minor bug fixes in filesystem operations
Some of the types in fileops tests were causing warnings to be thrown
during build, due to type mismatch. I've added a few local variables to
quiet these warnings.
* Implemented filesystem operations abstraction code
* Added filesystem operations abstraction unit tests
* Modified CMake configurations to support the building of the abstraction code and unit tests
Integrated process abstraction code into more locations
Defined new macros for abstracting across various platforms
Added GLOG_NO_ABBREVIATED_SEVERITIES for glog to support Windows
Fixed some minor CMake issues involving thrift
Updated gflags package; reflecting change in provision script
Preparing CMake config files for WIN32 support
When optimizing a table using query constraints an implementation should not add unneeded rows.
A user experience bug exists when selecting with an explicit non-existing pid/uid.
Boost property trees are level delimited using '.' characters.
An Apple property list may contain keys with '.' characters, so the plist conversion must use iterators and raw node appends.
1. Redhat-based distributions were not reporting their version correct.
2. The file read API assumed stat would return an accurate file size.
This has been replaced with an attempt to seek to the end of the file.
There are 3 new options that control how files are read:
--read_max: controls the maximum size, in bytes, for file reads. If a file is larger than `read_max` the read will fail.
--read_user_max: similar to `read_max` but applies additional limitations to user-controlled files.
--read_user_links: a boolean control to enable/disable following symlinks for user-controlled files.
Important highlights:
If files exceed the configured max, those reads will fail.
The `read_max` will override `read_user_max` if it is set lower.
A default integer value of `0` will disable the limitations.
The default `read_max` is set to 50M and the default `read_user_max` is 10M.
POSIX-globbing will allow event publishers/subscribers to post-check
results against glob-syntax, fnpath matching, and POSIX C-regex.
These checks are anecdotally speedy.
