initPatchTarget
public static SVNPatchTarget initPatchTarget(SVNPatch patch, java.io.File baseDir, int stripCount, SVNAdminArea wc) throws SVNException, java.io.IOException Attempt to initialize a patch TARGET structure for a target file described by PATCH. Use client context CTX to send notifiations and retrieve WC_CTX. STRIP_COUNT specifies the number of leading path components which should be stripped from target paths in the patch. Upon success, return the patch target structure. Else, return NULL.- Throws:
SVNException
java.io.IOException
-
detectFileEOL
private static java.lang.String detectFileEOL(java.io.RandomAccessFile file) throws java.io.IOException Detect the EOL marker used in file and return it. If it cannot be detected, return NULL. The file is searched starting at the current file cursor position. The first EOL marker found will be returnd. So if the file has inconsistent EOL markers, this won't be detected. Upon return, the original file cursor position is always preserved, even if an error is thrown.- Throws:
java.io.IOException
-
resolveTargetPath
private void resolveTargetPath(java.io.File pathFromPatchfile, java.io.File absWCPath, int stripCount, SVNAdminArea wc) throws SVNException, java.io.IOException Resolve the exact path for a patch TARGET at path PATH_FROM_PATCHFILE, which is the path of the target as it appeared in the patch file. Put a canonicalized version of PATH_FROM_PATCHFILE into TARGET->CANON_PATH_FROM_PATCHFILE. WC_CTX is a context for the working copy the patch is applied to. If possible, determine TARGET->WC_PATH, TARGET->ABS_PATH, TARGET->KIND, TARGET->ADDED, and TARGET->PARENT_DIR_EXISTS. Indicate in TARGET->SKIPPED whether the target should be skipped. STRIP_COUNT specifies the number of leading path components which should be stripped from target paths in the patch.- Throws:
SVNException
java.io.IOException
-
isChildPath
public static boolean isChildPath(java.io.File baseFile, java.io.File file) throws java.io.IOException - Throws:
java.io.IOException
-
getChildPath
private java.io.File getChildPath(java.io.File basePath, java.io.File childPath) throws java.io.IOException - Throws:
java.io.IOException
-
stripPath
public static java.io.File stripPath(java.io.File path, int stripCount) -
rejectHunk
Write the diff text of the hunk described by HI to the reject stream of TARGET, and mark TARGET as having had rejects.- Throws:
java.io.IOException
SVNException
-
applyHunk
Write the modified text of hunk described by HI to the patched stream of TARGET.- Throws:
SVNException
java.io.IOException
-
seekToLine
Seek to the specified LINE in TARGET. Mark any lines not read before in TARGET->LINES.- Throws:
SVNException
java.io.IOException
-
readLine
Read a *LINE from TARGET. If the line has not been read before mark the line in TARGET->LINES.- Throws:
SVNException
java.io.IOException
-
copyLinesToTarget
Copy lines to the patched stream until the specified LINE has been reached. Indicate in *EOF whether end-of-file was encountered while reading from the target. If LINE is zero, copy lines until end-of-file has been reached.- Throws:
java.io.IOException
SVNException
-
installPatchedTarget
public void installPatchedTarget(java.io.File absWCPath, boolean dryRun, SVNAdminArea wc) throws SVNException Install a patched TARGET into the working copy at ABS_WC_PATH. Use client context CTX to retrieve WC_CTX, and possibly doing notifications. If DRY_RUN is TRUE, don't modify the working copy.- Throws:
SVNException
-
decomposePath
public static java.lang.String[] decomposePath(java.io.File path) -
applyPatch
public static SVNPatchTarget applyPatch(SVNPatch patch, java.io.File absWCPath, int stripCount, SVNAdminArea wc) throws SVNException, java.io.IOException Apply a PATCH to a working copy at ABS_WC_PATH. STRIP_COUNT specifies the number of leading path components which should be stripped from target paths in the patch.- Throws:
SVNException
java.io.IOException
-
getHunkInfo
public SVNPatchHunkInfo getHunkInfo(SVNPatchHunk hunk, int fuzz) throws SVNException, java.io.IOException Determine the line at which a HUNK applies to the TARGET file, and return an appropriate hunk_info object in *HI, allocated from RESULT_POOL. Use fuzz factor FUZZ. Set HI->FUZZ to FUZZ. If no correct line can be determined, set HI->REJECTED to TRUE. When this function returns, neither TARGET->CURRENT_LINE nor the file offset in the target file will have changed.- Throws:
SVNException
java.io.IOException
-
scanForMatch
public int scanForMatch(SVNPatchHunk hunk, boolean matchFirst, int upperLine, int fuzz) throws SVNException, java.io.IOException Scan lines of TARGET for a match of the original text of HUNK, up to but not including the specified UPPER_LINE. Use fuzz factor FUZZ. If UPPER_LINE is zero scan until EOF occurs when reading from TARGET. Return the line at which HUNK was matched in *MATCHED_LINE. If the hunk did not match at all, set *MATCHED_LINE to zero. If the hunk matched multiple times, and MATCH_FIRST is TRUE, return the line number at which the first match occured in *MATCHED_LINE. If the hunk matched multiple times, and MATCH_FIRST is FALSE, return the line number at which the last match occured in *MATCHED_LINE.- Throws:
SVNException
java.io.IOException
-
matchHunk
Indicate in *MATCHED whether the original text of HUNK matches the patch TARGET at its current line. Lines within FUZZ lines of the start or end of HUNK will always match. When this function returns, neither TARGET->CURRENT_LINE nor the file offset in the target file will have changed. HUNK->ORIGINAL_TEXT will be reset.- Throws:
SVNException
java.io.IOException
-
tryWrite
private void tryWrite(java.io.OutputStream stream, java.lang.StringBuffer buffer) throws java.io.IOException Attempt to write LEN bytes of DATA to STREAM, the underlying file of which is at ABSPATH. Fail if not all bytes could be written to the stream.- Throws:
java.io.IOException
-
sendPatchNotification
Use client context CTX to send a suitable notification for a patch TARGET.- Throws:
SVNException
