Relying on `diff` for storing the pre-change content did not work out as it opens the file descriptors to soon and only reads the first block of pre-change file content until the remaining content is actually required. This obviously led to problems when tracking actually changing files.
|
|
This obviously leads to synchronizing syscalls that would otherwise happen in parallel. Luckily the goal of this library is to monitor file changes performed by single, user facing applications and as such it doesn't matter if some operations are slightly slower.
|
|
This ensures that the log file is actually accessable - there was a problem where e.g. `change rm test` did not create the log file correctly.
|
|
i.e. enable writing `change vim test` instead of `change "vim test"`.
|
|
|
|
`change` calls the given command wrapped in `libChangeLog` and prints the recorded change log afterwards.
|

Prevents the same file being tracked multiple times due to relative input paths.
|
|
While the file arguments remain fixed the actual `diff` application and its output style can be changed using the `CHANGE_LOG_DIFF_CMD` environment variable.
|
|
|
|
The library is designed to track the file changes performed by a single process, i.e. there is no need for explicitly stating when the process has exited. Furthermore this reduces the set of function interpositions to the ones handled by the `get_actual_function` method template.
|
|
|
|
The newly introduced `ChangeTracker` class is now keeping track of all tracked file in addition to spawning and managing a corresponding `diff` instance that enables printing pretty _patch-style_ change summaries to the logging target.
This commit introduces `boost-process` and `diff` as dependencies of this library.

|

The pointers to the actual function implementations are now fetched inside the `actual` namespace declared in the `actual_function.h` header.
Fixed source of _noreturn_ related warning during compilation by adding the appropriate flag. Sadly this means that we can not use `std::function` in this context as it doesn't seem to carry these _c-like_ flags.

The `CHANGE_LOG_TARGET` environment variable enables passing the path of an arbitrary target file to the preloaded library.
This may be used to e.g. print the log to a separate `cat` instance and is necessary for logging change events without altering the output of the wrapped process.

The goal is to implement a shared library to be loaded using `LD_PRELOAD` that tracks all file changes performed by a process.
This information is required to enable general purpose change logging inside a shell session. i.e. I want to be able to display diffs and before- / after-hashes of all changes performed by every single command without requiring every changed file to be known prior to execution.
